Got a couple USB power bank cases. Not long after installed batteries, one is already no where to be found.

Got also three more charge doctors. At less than $2 each, I feel every USB charger in use should have one of these on.

And, ya, a Fluke863 for about $100 can be counted as a purchase of recent month. it had a few blank lines and needed to put some pressure on the ribbon connector to fix.

Not as flouty as the French stuff but I've just had a flatcake breakfast from my regular greasy spoon. They're normally a bit overbearing but this one took me an hour to eat and I don't think I'll need anythig else for days lol.

Not a purchase but apparently I'm recieving a box full of 4PDT relays later today...

On Friday, I received orders for 2 of my Generator Autostart ATS Control Panels.
Spent some time on Saturday, and most of this afternoon completing the board layout.

then this evening I Just spent over ZAR700 (about a tank of petrol) with ITEADSTUDIO
for 10 off 10x10cm Prototype PCB's
Most of the cost was for the DHL shipping.

I just couldn't wait 4 months for the standard shipping.

Now I have my fingers crossed that they will arrive in 2 weeks!

Today I scored a Fluke 87 V on Craigslist.

It is brand new, was sealed and never used!  Seller was asking $250, I offered $185 and picked it up!

The serial number is older, 11180329 so i guess it may have some of those issues I read about.  Anyone have thoughts on that?
I think this was a good price.  Here is a picture (It came with sealed box, matching serial #, etc, but I opened it):

Well that has kind of made my day, my scope was only sent yesterday by courier, it says it is out for delivery to me , never had hermes do anything that fast overnight !.

Being Hermes, they might chuck it over your fence yet or end up taking it back to the depot and using it as a football. I was thinking about shipping a data logger with accelerometer with them to see what the max G was...

I think performing taxidermy on the delivery driver and standing him outside as an eternal warning to others against being a total git is appropriate.

Still waiting for my pad boards from one after three weeks. It's got so bad I used stripboard the other day. Never again. Ordered some extras from Bitsbox.co.uk and got them next day.

Most recent purchases:
- 14 new mugs with print, for my "Daily Mug" habit at my part-time job. (I try to have a comedic/sarcastic/angry pre-printed mug with a different print every day I work there for as long a stretch as my budget can reach. Forcing me to shop creatively for bargains and trade mugs with other people, but I'm up to 43 different mugs now.)
- Clevo i7/GTX970 laptop with poop-loads of SSD, because reasons.
- High flexibility silicone/litz wire, which is going to be loaded onto a boat soon in the east, for my Company/Freelance stock.

Otherwise, mainly fruits, vegetables, milk and small amounts of bread and meats.

Delivery guy had a fit when i told him what it was in the box and he muttered about how it was heavy carrying it to the top of the flats.I offered him a Rich tea Biscuit which he refused with a look of disgust. now to bed for a bit as been up all night.

Perhaps having the guy drawn, quartered, and head set on a pike along with the damaged item with a "This is what you get when..." plaque on display might be a more effective deterrent.  :o  >:D

It has a hollow shaft so I can run a vacuum through it.

End up pulling out the canner for jams, beans, soups and potatoes so I do the pasta sauce at the same time. I love the fact that everything in the can is cooked so when I am feeling lazy I dont have to cook, just dump out the can and heat it up. I do alot of pressure cooked meals in a can with beans, meat, veggies and some nice gravy or sauce.

Must be the anchovies....... I do kind of like fish, especially a nice bit of butterfish, though you really need a second plate for the bone plates ( one nice slice will make 2 plates of bone plate for some reason) and the next morning you know all about it.

Currently I am going through a few cans of ready made sauce, appropriately called "Lord of the Ring", which has a nice mild taste, and it is nice and tasty. some people complain that it is too hot, but I quite like it, it goes down well with some steak or chops, or I stuff bell peppers with it and grill them over the coals.

Strange with the sauces, particularly the Bolognese (who doesn't like meat, onion, and carrots ? and maybe some wine  >:D).  :-// How do you make it if you don't mind sharing?
 

I'm with SeanB on it being the anchovies. Maybe go with a lighter species (and pick it clean of any bones during prep) or shift the meat entirely. Well seasoned chicken perhaps if there's no way they'd touch fish of any kind.

Try some nice Cape Snoek, nicely smoked and salted, grilled lightly over the coals, with apricot jam as a marinade. Then you can do the interesting thing called Bokkoms, salted dried small fish, best reserved for feeding the cat as a treat. Could never get the taste for pickled herring, it just is not me.

As to buying things, still waiting for them to make their way through the Byzantine maze that is SAPO.

I will saute onions, carrots and bell peppers w/  sea salt, pepper and unsalted butter.  For meat, it is the triumvirate-ground beef, pork and veal, sauteed and drained.  All goes in the pot and I add canned tomato sauce, canned crushed tomatoes, tomato paste and extra virgin olive oil.  I add the typical "Italian" seasonings-parsley, sage, basil, rosemary, thyme, marjoram,sea salt and fresh ground pepper.  I also add about a half a cup of a cheap Burgundy wine.  Nothing I could stand to drink but it works wonders for the flavor of the sauce.  I also add some grated Romano cheese.  I let the sauce simmer, covered, for 2-2.5 hours, no longer.  I can't give measurements, I don't cook like that.  If the house smells like when I was growing up then I know it is correct.  My wife actually tried to get me to produce a real recipe for my marinara.  I spent an exorbitant amount of time measuring, tasting, measuring more, writing everything down, etc, ad nauseum, and it was the worst pot of sauce I ever made, almost inedible. |O  She apologized for that.

When the first film came out I initially thought that everyone was raving about a S&M gay porno or something :-// Sitting through the film admittedly wasn't quite as horrible an experience as I'd imaging sitting through a S&M gay porno would be, but not that far off either.

Fish and chips from a stall at the fair (one of the things I miss from my time in the UK) followed by a chocolate kebab with marshmellow and chocolate sauce topping. Enough carbs to last the weekend.

Funny I have a craving for fish and chips, so I guess that's what I'll get tomorrow from the closest bar from home (5 minutes walk) There is also another place that is a 10 minute walk that has better fish and chips, but I rather go to the bar and have some Unibroue beer, maybe a couple of Maudites will do.

I love Chicago! I have over around 70 restaurants within 20 minutes walking distance from home!

Edit: And no! I don't count fast food places as restaurants :)

Down here we get Man vs Food and some other show that I forget the name of (with two aging ugly guys cruising from American restaurant to restaurant in a convertible) screened on TV. The so-called "fine American cuisine" that these guys drool over and enthusiastically celebrate beggars belief. Typical examples not yet erased from my memory are a plate sporting a kilo and a half of deep fried shit served with two or three ladles of "sloppy Joe" poured on top, a burger made with a Krispy Kreme glazed donut as a bun substitute, battered and deep fried chicken wings served on waffles, deep fried shit served with an extra serving of deep fried shit then some some chilli sauce and ketchup ladled over the top followed by half a pound of melted cheese. It's little wonder that Americans are so overtly religious; when premature death by coronary disease is imminent I guess it is comforting to have a backup plan in Jesus.

Took delivery of a HP 3611 in very nice condition, ordered the E3600A-100 Test Lead Kit.

Then, I ordered a NI myDAQ with LabView and MultiSim. 

I was originally looking at taking an older NI ELVIS (version 1) system, and somehow getting it to work with my system, but it doesn't seem worth it, its tied to older drivers, older OS, and not very supported.  A newer ELVIS II is like $3000!  But for ~$200 I couldn't say no to a myDAQ, the specs are really nice on it and the curriculum is online for free at ni.com.  I will likely add in the Circuits book which has been updated to follow along with this device!

Not so much a purchase, rather a rescue from the garbage believe it or not!

2x 24-port Cisco Catalyst 3750 v2 POE Switches complete with a set of stack cables and 4x 1Gbit multimode fibre GBIC modules. Both work perfectly, just erase the config and off they went.

The copper ports are only 10/100 but still more than adequate for most purposes (including HD video).

It's fairly common among big enterprise and Government departments. When they do a network refresh, especially if they've sat inside a protected network, rather than being erased and reused or sold, they just bin or shred them (literally). They don't care. The cost of disposal is factored into their budgets.

It pays to be friendly with IT guys :-)

Not just Big Enterprise and Govt.
We are fairly small by those standards and we simply destroy the equipment and bin it.
It costs too much to erase securely and then go to the trouble of selling, or even giving it away.
Desktops and Laptops are way more hassle than things like switching equipment, but we just do the lot.

No pictures yet sorry, need to clear out space for my corner for it first. After that i will consider posting in home-lab picture thread.. But its Hitachi V665 60MHz, 2 Ch.. Arrived this morning and had it run throw usual tests, passed all with flying colors. Had to buy probes separately, so had to calibrate those as well.. Not bad priced considering i live in Finland where everything is usually expensive. Old piece of gear, but still fully working.

FWIW, I found that Kleen Strip's SDX Denatured Alcohol is a cheaper alternative (~50/50 mix of ethanol & methanol; denaturing agent, MIBK, is also a solvent). Locally, it runs $15.98 per gallon in Home Depot.

After missing the first round of closures, my local "Shack" got put on the close list a couple of months ago.  I ponied up for one of their component cases but had to wait until it had emptied out before picking it up. They called me yesterday so I stopped by to get it .  That thing is heavy!  Definitely made to last.

While there, with everything 70-80% off, I couldn't help buy some uneeded things, including 2 of their "top of the line" multimeters.  6000 count true RMS and PC interface for $21 each (marked down from $70).  The last thing I need is another multimeter but for the price I couldn't resist.  One will probably end up as a Xmas present for my 9 year old son, but the other? --  I haven't decided yet.

$175 :-[  I hemmed and hawed about the price but I do think it is worth it. It is one of those lasts-a-lifetime pieces of gear - likely passed on to my kids.

Tell-tale signs?  Well, in the case of the store here a large sign appeared outside saying  "Store Closing".

I've been stopping by once a week or so since they announced it. Each week or so new signs show up on the windows -- 30-50% off then 40-60% and so on until now 70-80%.

I've picked up a few things along the way as the stock was whittled away.  The exact close day is top secret but the manager told me that they'll but a sign up that says "last 10 days" when the time comes.

I've got my eye on a few more things if prices drop more, I'd love to pick up a boat load of rechargable NiMH batteries. They've go a ton of them in stock but at 70% off their still a bit pricey.

The manager at my local Radio Shack says they will be open until the end of the month.  There isn't much left but a ton of batteries and headphones (mostly ear buds).  Oh, and HDMI cables.  A wall full of HDMI cables.  He also said that for their last 10 days they plan to have a bag sale.  Buy a bag for $10 and stuff it full of anything that fits.   I'm wondering what will be left and if I should stuff the bag with things for myself or things I can unload on eBay like cell phone cases and phone batteries.  I'm thinking I'll have to be there on the first day of the 10 days to get anything good.

With as many ear bud headphones as I have had go bad, the wire breaking at the plug, I should fill a bag for myself and quit spending time on re-soldering the plugs.

As for my purchases, last time I got a crappy clip on smartphone microscope that doesn't even work.  Shows an image about the size of a dime in the middle of my 5 inch phone screen.   Previous trip I picked up 4 rolls of kynar wire wrap wire and a tube of somewhat conductive ink for less than $10.

this thread should really come with a warning... Make sure you pay the rent and bills BEFORE you buy shiny new gadgets... I forgot them in the excitement. In fact the forum should have a warning of such and how addictive it is.  |O :-DD

Deathwish, I just got the same LA.  I haven't actually used it yet, but I installed the Saleae Logic software, ver 1.1.15 and the software reports it as a Saleae LA and it paired up immediately.  Win 7 Ultimate 32 bit also installed the driver without an issue.

Bought THIS (http://www.ebay.com/itm/291486811041?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649) a few days ago. It's on its way here now. Surprised me when my offer of $100 was accepted!   Can't wait to play with some high voltage (low energy) circuits... >:D

BTW - the same seller has another one - slightly less pristine looking - listed for $149...

Four 50W LEDs. One each R, G, B & Cool White.
I'm starting on my next 'microscope light' project. This one a bit more powerful than the last. http://everist.org/NobLog/20150510_Olympus_bhm.htm (http://everist.org/NobLog/20150510_Olympus_bhm.htm) That was 10W, this one will be 200 to 300W max, adjustable for normally lower output.

The aim is to get all the light from these mixed and steered down to a small diffuser aperture about 3mm diameter. Or less, maybe. I think it will be something unwise to look at when lit.
Lens coupling from the small aperture to the microscope.
Maybe I'll be adding 50W UV and IR LEDs too. Still looking for R & G 50W LEDs that are not pathetic in output compared to the Blue/White ones. Seems sad that R & G LEDs lag so much in efficiency.
Anyway, the idea is to have individual current drivers, for an adjustable spectral distribution.

Pics are the bare LEDs, then mounted on heatsinks with fans.

Oh, and I bought 200 ordinary 5mm Red-Green bicolor LEDs, for that 'magic LED ball' experiment. In the post.
See https://www.eevblog.com/forum/projects/magic-led-ball/ (https://www.eevblog.com/forum/projects/magic-led-ball/)

Edit: Correction. I take back that bit about the green having pathetic efficiency. Also that these would be eye hazards once concentrated to a near point. Powered up, the green is completely impossible to look at. I made the mistake of looking at it for a very brief instant just before leaving to drive to pick up a pizza (at night.) Mistake.

These were from ebay http://www.ebay.com.au/itm/111299756188 (http://www.ebay.com.au/itm/111299756188)
50W Color: Cool White    USD$2.99   AU$3.85
50W Color: Red           $3.13   4.03
50W Color: Green         $2.89   3.72
50W Color: Blue          $2.99   3.85

Operating: DC32-36V   1750mA

Red         620-625nm   500-550lm    <---
Green       520-525nm   500-550lm    <--- perhaps these '500 lm' are plain wrong?
Blue        450-460nm   2500-3000lm
Amber       585-590nm   2500-3000lm
Cool White  6000K-6500K 6000-7000lm
Warm White  3000K-3500K 6000-7000lm

It's interesting how much more sensitive eyes are to green than blue. On the same drive power, the green looks *much* brighter than the blue (going by reflections, not directly looking at it.) Yet the simple 'how close can I hold my fingertip' test says the blue is outputting easily twice the radiant energy. 'Ouchy' distance is about 2 cm for the blue, 1cm for the green.

I still find the idea of an LED you can't hold your finger next to amazing.
It's a relief to find these heatsink-fan units are adequate for 50W LEDs.  But only with fans going at full 12V. Dropped to 5V, they warm up fast.

Hmm... I'm starting to wonder if all of these actually have blue LEDs under the phosphor. When I put the Red, Green and White LEDs (unpowered) in the light from the Blue one, their cover materials all fluoresce brilliantly. The Red and Green ones are not just tinted covers over Red and Green LED chips.
Pics below don't capture the effect

I recently bought some 320x340 SPI 2.2" LCDs for something below 5€ which I wanted to use as default display for future projects.
Now I found some 2.4" displays with the same controller (ILI9341) and additional touchscreen (also kinda SPI) for slightly below 6€.
Couldn't resist.

Just scored a Panasonic Lumix DMC-SZ8 Camera from Officeworks for $40, they were clearing these out for $58 and the only one left locally was as new but missing the 240 to 5 volt USB charger so I took one that I had for my phone to the store and asked to test it first, worked a treat, happy as larry I was.

Basic auto focus point and click camera with 3 inch screen, looked bigger in the pictures, next time I will take more notice of the dimensions in the specs. Also it uses a proprietary 8 pin micro type USB connector for charging and data transfer, one manual said no charging through the port and other documentation indicated that USB charging through the supplied cable was fine, didn't risk it so checked before hand.

I despise proprietary connectors and hate conflicting documentation even more so.

A new drain pump for our Bosch Nexxt 300 series washer.  Damn washer broke down just before company came to visit.  A new pump was $75 shipped, 4 days to the door and was fairly simple to change out, outside of the traditional bloodletting along my arm from squeezing into a tight place to remove hoses.  After almost all the towels in the house were used up going to the beach, it took 2 full days to catch up on all the laundry.  I should have listened to SWMBO and used the local laundromat and get everything done at once. :palm:

As a side note, the Bosch Nexxt 300 series combo is the worst combo we have ever owned.  The washer has been finicky since day one and the dryer blows the temperature limiter once a year.  Luckily the part is cheap and easy to change after getting the 1/2 ton of screws out of the back.  Any setting other than regular dry results in the clothes smelling like they were burnt.  I wouldn't be surprised if we could smelt metal on the extra dry setting.  All this for only $1600 USD for the set.  When these finally die, we will get anything but Bosch.

Ended up bugging TopLoser for one, and he gave me a great deal - I felt so bad when I had to decline! Got an email notification from a local "ebay", someone selling a Philips/Fluke PM97 just down the road (3 minutes walk).  Went down immediately and here it is:

Actually I build a lot of stuff!  But After selling my old rigs, I wanted to get back on the air asap.  So this is what I did.  I plan to build some SDR's and QRP rigs, as well as some antennas.  One of the things I am building right now is a Go Box with solar controller, AGM battery, a panel, power buses, etc.

Time is a premium for me though, so I have to be careful about what I decide to take on.

I am also building a workbench for a lot of this stuff to live on, so wood, miter saw, ground bus bars, basic stuff, but takes time.

Well, went to the dentist today for a check up, and asked him if he had any old dental picks he was going to throw away.  So got an assortment of 5 dental picks, a set of tweezers and 2 special tools, plus a bit of mercury amalgam that was hiding inside, which had survived a good few autoclave cycles.

Bonus points if anyone can identify the 2 tools on the right, as I doubt many have seen them before. I don't know if I will use them as is, but they might come in useful.

Was chatting after the polish ( interesting that the burnishing tool is a plain disk of SRBP material used to abrade your tooth, used once and then thrown away) and when he upgrades the Xray he will call me........ now I have to find some scintillator film in the interim, to make up an imager using an old CCD camera or just a camera obscura with the sheet and a sacrificial cheapie camera I have around.

That was quick Robrenz......... They had the amalgam inside the springs. Took a while to get the one to move freelt, it was so full in the tip area. He rarely uses amalgam these days, as he has gone mostly to composite fillings and UV cure resin. Still has the amalgam equipment, but it is rarely used and only for some places. Next year he wants to replace my amalgam fillings, as they are aging, but still in very good condition.

One of those cheap-arse Chinese vacuum hold-down pivoting vices.

I'd never bought one before, due to my workbenches usually being wood-topped. Which are too rough and porous to hold a suction cap seal. But now my soldering desk has a mirror finish ceramic tile top, which works as well as glass with the suction cap.

Recently I looked these up on ebay-from-China, and found prices of Au$31 (free post), or Au$20+$12.50 postage. I'd intended to buy one the next time I ordered some stuff.
Yesterday I happened to be in Jaycar Bankstown, and their price for the exact same model is Au$29.95. Ha ha... I wonder what their import landed price was?

Anyway, it's one of those simple, cheap but never-quite-happened things I've wanted for most of my life.
They are cheap diecast, wouldn't do for any rough work, but are great for holding circuit boards while soldering. The jaws are steel, with V-grooves and rubber clip-on soft-jaws.

By the way, those tiles are 600mm square, hard vitreous stoneware ceramic, and come in 3-packs for about $12 a pack from Bunnings.  I happened to also have a few half width ones in a different color I'd found in a dumpster ages ago. Together they fit the table very well.

They are quite thermally conductive, so feel cold to the touch in cold weather. If that was a bench where I sat writing or using keyboard/mouse for long, it would be uncomfortable. But it's a workspace dedicated to soldering (and using microscopes.) So it doesn't seem to be a problem, since my hands don't rest on the bench much.
Also, the tiles are not fixed down. I could easily take them off temporarily if needed. There's a sheet of 3mm MDF underneath, to protect the table surface. The table is a sentimental heirloom - made by my grandfather.

I did have a coldness problem with a thick aluminum 'computer tray' in a rack. Using the mouse on that was quite unpleasant. But easily solved with a mousemat. When I get the cameras for microscopes sorted out, and have to use the mouse at the soldering desk a bit, I can add a mouse mat here too.

Re the suction cap leaking - wipe the surface and suction cap with a damp cloth first. On a glass-smooth surface it makes a perfect seal. I test-stuck that vice down yesterday and it's still solidly attached.

...They are quite thermally conductive, so feel cold to the touch in cold weather. If that was a bench where I sat writing or using keyboard/mouse for long, it would be uncomfortable...

Yes, I figured they might be a bit cold... I tend to "elbow rest" in my workspace, except while soldering of course...
Thanks for your feedback TerraHertz.

The cheap benchtop vice at Aldi are Workzone brand and jave been historically been on sale at $15 (only during Feb) until sold out. I preferred the suction cup version, and while they aren't perfect you can mount it on block of wood (for example) and put it anywhere on the table. It's also heavy enough to do smaller jobs without anchoring.

Or you can buy the exact same vice for twice the price if you choose the Proxxon labelled version: http://www.axminster.co.uk/proxxon-fms-75-precision-vice (http://www.axminster.co.uk/proxxon-fms-75-precision-vice)

for $3.32


I only needed about 5 of them. Now I need to figure out what to do with the rest. They are very useful little chips, especially for driving relays with a PIC micro...

I rarely get sick but have been suffering with the flu for almost a week now, really bad throbbing headaches, runny nose, watering eyes, sore throat and crook in the guts, probably  all the symptoms associated with scurvy or the plague with my luck.

I squeezed some lemons over the weekend and made some hot lemon drinks just with hot water and a bit of sugar, always worked in the past but just not doing the job on this one.
Went to the chemist and spent a fortune on lozenges, throat spray and medicated tablets but having little effect, I must say that I was tempted as the bottle shop was only a couple of doors down from the chemist and surely a bottle of bourbon couldn't make me feel any worse off, I refrained of course.

Anyway, since nothing else is working I figured the best way to get rid of the flu was to share it.

That reminds me of a funny thing, we were on a big factory job once and hadn't eaten all day so we decided to get a couple of pizza's delivered to the site, It was late at night and when I rang them I asked how long it would take before delivery, the person replied one hour and sixty minutes, I told them not to bother.

I know that we are off topic and we can go back and thin it out if required or asked, but last yesterday was the worst for the runny nose, all day long, two big boxes of tissues gone and dozens of handkerchiefs now contaminated, At one point I even considered going out into the workshop and getting the silicone gun, seems to work for the plumbers.

Years ago someone told me that to stop a runny nose you should snort some black pepper anyway silly me tried it in desperation once, sneezed and almost blew my head off, never again.

A few minor odds and ends:
 * 12V 12.5A power supply, for 'some stuff running in a cupboard'. The short leads were just so I could power it up. Still have to try it under full load for a while as a test.

 * A bag or 200 Red/Green LEDs. For that electrostatic 'sparkle ball' experiment.
 * Box of just under 1000 M3 CSK 8mm stainless steel screws. I'm lucky to live very near an industrial manufacturer and stockist of fasteners. Cheap and friendly. Premier Fasteners of Milperra.
 * Bag of 100 ziplock plastic bags, 250x170mm. I use these for storing all those little B5 size booklets and papers that come with so many electronic things. A bag for each item, keeps the manual, CD and my notes together, and the bags fit perfectly in those common small storage cubes, like at left. Now I won't run out again for a while.

Incidentally, about those 50W LEDs I bought recently, see: http://everist.org/NobLog/20150628_LED_lighting_mk3.htm (http://everist.org/NobLog/20150628_LED_lighting_mk3.htm)

When is a 'red LED' not a red LED? A: when it's one of those. Beware.

Got a parcel today from Toploser.......

The items I paid for, the Bourns pots and the peltier cooler units ( bare unsealed devices) plus some eztra packaging material in the carton to stop it rattling.

Cheaper than packing peanuts. so I got a few UV led units ( either UV or really royal blue, can't decide, so I will have to look at them further. Really nice die inside, with a gold top metal layer and gold bond wires as well, must pop one under the microscope), some IGBT devices ( nice!) and enough 0R1 SMD resistors to make a dummy load or hundred with.

Thanks Ian! I like your scrap packing material, a good mystery bonus there.

I have a T420s at home and the trackpad is perfectly fine.  Some coworkers at work have a T430, T530, and first get X1 carbon, all have decent trackpads.  I did get a T440 at work though with the unholy "clickpad" abomination they introduced last year...that thing is the worst pointing device I have ever used on a computer.  Apparently they received so many complaints that for 2015 they reverted the entire product line back to the traditional trackpad, so I don't expect any problems with this one.

Got a set of six 350 Farad 2.7V ultracapacitors to attach across the car battery to give the 5 litre V8 a bit more of a shove when starting, particularly on cold mornings. You can even start the car without a battery, just using the caps only, but a battery + cap combo is the ideal setup. Even if the battery is so cold, old or sad that the starter solenoid just chatters, one of these fitted will make it crank over like a new battery.

It will be used for general purpose everything.

My current "lab machine/server" will be moved to dedicated server-only duty, my current general purpose T420s will move to lab duty, and the X1 Carbon will take the place of the T420s.  It'll mostly be kicad, programming, general on-site equipment testing/debugging, etc.  The first thing I'm going to do when I get it is wipe it and install OpenSUSE Tumbleweed, then I'll probably stick Windows 10 in a VM for the tasks that still require Windows.

Unfortunately Lenovo just pushed the estimated ship date back 10 days to July 17, so who knows when it'll get here.  Hopefully it shows up before my trip to Peru in August, I could use it on that long flight.

Hi

I got the R6144 two weeks ago, seller said it was noisy and it is, the LT1021-7 is giving up the ghost, waiting for a replacement.

The 199 I got today, apparently powers up but not tested, but it didn't. One of the primary side coils on the main transformer was open, where the PCB pin meets the wire. Fixed that and now it just reads garbage. Probably sumpthing in the ADC.

Bonus the longest boge wire I have seen

Would these outlast the battery if permanently attached or would you have to keep them separate and only use when necessary?

Got a set of six 350 Farad 2.7V ultracapacitors to attach across the car battery to give the 5 litre V8 a bit more of a shove when starting, particularly on cold mornings. You can even start the car without a battery, just using the caps only, but a battery + cap combo is the ideal setup. Even if the battery is so cold, old or sad that the starter solenoid just chatters, one of these fitted will make it crank over like a new battery.
Interesting....
Can you show a picture of the other side with the balancing circuit?
How is the balancing solved for these Maxwell capacitors?
Where did you buy the unit of the PCB?
How did you interface the heavy cables to the PCB?

A box of NOS adjustable 15W power resistors.
1984 vintage, look nice...
And that's all they do, unfortunately.

Specced at 1.5Ohm, +-5% they actually read 5.1 Ohm.
Also, the tweaker does not really work - there is no contact most of the time even after cleaning the resistive wire of corrosion.
They seem to all have about the same wrong resistance, so either i understand the labelling wrong (1.5 Ohm resistor. How can it mean 5.1 Ohm? Did they print the digits in the wrong order?), or they have degraded over time.

Well, back to looking for a tweakable 0.41 Ohm sense resistor in the 5W range...

I'd expect them to last for many years provided you don't let them get way too hot. Keep them across the battery permanently. Have a search on YouTube.

If you scroll down there is a full schematic.  It looks like they have used a combination of light emitting and normal diodes to get something a little below the 2.7V max of each cap.

But I never owned an X1 Carbon
Will you be running it for engineering purposes?
May be you can share your experiences

It arrived today.  It feels very well built, small, and incredibly light.  First thing I did when I got it was backup the restore partition and then wipe the drive and install Linux, then install Windows 7 in a VM.  Everything is working out of the box, no hiccups.  The processor is nothing to write home about, Intel hasn't really improved processing power versus the standard notebook processors from 3 years ago, but what they have done is cut the power requirements of the processor in half and improved the graphics capabilities.  So same processing power as a few years ago, but better graphics and significantly lower power.  In addition to the improved battery life this gives, it also means the machine runs cool and quiet regardless of what you're doing on it.  It's spent the last 2 hours with the CPU running 100% (Windows updates) and you can hardly hear the fan and it's barely warm to the touch.

The PCIe x4 drive is SUPER fast  too, I got an average of 1.3 GB/s write and 1.1 GB/s read on a 50 GB dd dump, WHILE simultaneously installing a program on Linux, doing system updates on the Win 7 VM, and installing two programs on the Win 7 VM.

I'm happy with it, it should be a very nice machine for my uses.  I just wish they offered a 16 GB RAM option for it...

They have multiple warehouses, so if the order has to be filled from more than one, your order will show up in multiple packages (and don't always arrive on the same day). Ordering something not in stock can cause this as well.

FWIW, I ran into both situations. 8)

I bought an FDAI (Flight Director/Attitude Indicator), along with 2 Arduino Mega2560s and 4 Pro Minis (clones from Microcenter). SADLY... the only serial interface for the micros they had in stock was the FTDI version... (I did not like paying any kind of money for an FTDI product). The arduinos are my first foray into microcontrollers. Call me old school... I've had a preference for digital logic for years, but I need to build some new skills. I haven't programed since the Commodore 64 days, and HyperCard and HyperStudio on Mac.

I'll be using the FDAI, along with a variety of meters, displays, indicators, switches, buttons, and other controls to build a "Command Module" styled controller for Kerbal Space Program. The Ratheon chip has a 1974 date code. This puppy is five years older than I am!

Yep, a Fordson E1A New Major. AFAIK it has the original diesel engine (only 35ish hp) but I'm not an expert on these so could be wrong. After some more poking around last night, it turns out the broken/seized gearbox it had was just a stuck handbrake mechanism, happy smiles all round.

I might start on some re-wiring tonight. It's all mostly working but I think some new crimp terminals and some emery paper and switch cleaner will do it the world of good.

Not a purchase but I've just been given a box full of Amiga 600s and 1200s, 2 Atari STEs and a Falcon.

None of the Amigas were meant to be working but it turns out that all of the PSUs had died* and they work fine with the ones I have apart from 1 having a dodgy keyboard and another needing a floppy drive (already replaced lol). Apart from those two issues all of them are mint, in boxes, and have all the bundled disks, manuals, leads etc plus some extras. I'm going to be tight and swap the Falcon and one A1200 for some consoles and bundle in some games in a charity auction as 1) while the A1200 may be better for gaming than the Falcon neither are as well supported as their 16 bit antecedents for gaming and it's a gaming themed auction the machines are going to and 2) I don't have either but with them I only need a Mega ST to complete my ST/Amiga collection.


*I did inform the person who gave me them of that because they gave me them thinking I may be able to cannibalise them to get a couple of working systems, but seeing as most of them will be auctioned for charity they don't want them back.

If they are being auctioned to non-electronics people, you'd probably be best off replacing the electrolytics in the A600s and A1200s, they are usually leaking by now.

I've had a cursory look over and everything seems fine, but I will indeed have a proper look over them and replace anything I think needs it before the auction. I wouldn't be surprised if that's all that's wrong with the Amiga PSUs. I'll be swapping out the ST PSUs for already refurbished, tested, and known good units too. But honestly every single one of these machines except for what I'm guessing was the most used A1200* not only looked brand new but smelled it when opened too lol.

*Heavily upgraded, it was also the one with the faulty floppy drive. <--That's the one I'm keeping but may "downgrade" it a bit to make it more standard. That all depends on compatibility though.

Even more heavily upgraded than I thought. What I thought was just a 68040 accelerator card is a BlizzardPPC  with a socketed 60Mhz full 68060 and (like the base A1200) maxed out on RAM upgrades.

Not sure if I should feel guilty or chuffed. Will have to get in touch with who gave me them again. If they still have no problem will have to swap it out for the 68EC060 I've got laying about that I know for some reason just so happens to have a working MMU and FPU and put the full fat chip into something more suitable.

She only goes for my tweezers.  They are in a different drawer than the flush cutters.  If she ever grabs it and uses it to cut nails, I will give it to her and go pull out 1 of my 2 identical spares. :-+  The files are also buried in the top section of the toolbox under a bunch of other stuff.  She won't go through the effort of looking (I hope).  It has to be a quick snatch and grab.

Has the typical issues with radios this old - volume and tone pots noisy, and also the selectivity switch. The back-up battery needs to be replaced, and then the typical clean-up. But I'm pretty pleased with what I got.  :)

Nice score X.  It wasn't a purchase so doesn't actually qualify for the thread, but I did a radio trade with a fellow club member.  He is very involved with the National Traffic system and was using a Yeasu FT-1000MP for passing digital traffic, though the radio wasn't well suited for it and was always giving him issues.  I traded him a Kenwood TS-850S with the IF-232 interface for the Yeasu ad he threw in a Yeasu SP-8 speaker.  He kept the mike because he knew I was getting the better end of the deal and since I use headset/boom mics anyway, it didn't matter.  Dollar wise, we both spent about the same amount of money, but the Yeasu is a better radio.  It is way nice to have a radio with a second receiver, makes working split much easier.  I am still keeping my Kenwood TS-940SAT, I wouldn't trade that for anything (OK, maybe a Kenwood 990), but it might become my backup radio.

I haven't bought anything recently but I did trade my labor for an HP-5245L counter with VHF, and UHF converters. (http://i558.photobucket.com/albums/ss21/AF6LJ/Stuff/My%20Gear/IMG_0316_zpsxovvto7w.jpg) (http://s558.photobucket.com/user/AF6LJ/media/Stuff/My%20Gear/IMG_0316_zpsxovvto7w.jpg.html)
I like old gear, this is all discreet transistor diode logic, so when a decade counter goes bad you fix it.

Cool.  :)

I've been going through the service manual checks and adjustments for the R-2000 today. Most everything is pretty spot-on. It's working good and although it doesn't hold a candle to today's modern DSP receivers, it's still fun to tune the shortwave bands with, for a retro sort of adventure. I need to retrofit it with an LED next. The whole radio had but a single incandescent lamp, and it was for the S-meter. The LED conversion is child's play and will look good.

But if you like that one - wait till I show you what's arriving next off Eaby. Just stay tuned ...  :-/O

Agilent N1996A spectrum analyzer. Talk about good times, 100 kHz to 6 GHz with 10 Hz RBW and tracking gen 1 MHz through 6 GHz. Built in return loss bridge, cable fault analysis, modulation analysis, AM/FM demod and spectrograph(waterfall) display. The spectrum analyzer actually goes to < 9 kHz and the tracking gen still works at 100 kHz. So much fun to be had! I now know the length of every piece of coax in the shack, it even measured the jumpers that are under a foot in length. It will be fun to sweep some antennas in the 5 GHz range once I build some decent open/short/loads and get more adapters.

Keithley 2000 in perfect working condition calibrated 2 years ago, located 10km from me for 200 CHF (~200 USD/280AUD).
Sadly no printed manual, but Keythley manuals are available on their website. Pics when I get it on thursday.
Got it for 100 CHF/USD, because the soft keys were a bit hard to press and because the seller knows the university where I study.
Cleaned the key membrane, now the keys are like newa.
The case is a bit yellowish but this can be expected for a 1996 vintage instrument, can this be reverted? (bleach the case in a ultrasonic bath?)
The firmware is A06, I ordered some EPROMs to update (seriously, why are there UV-erasable EPROMs without window? I'm so tempted to just decap them).
Electrolytics look good, instrument was used every 2 years (for calibration) according to the owner. Should I replace them nonetheless?

Edit: I will replace the electrolytics with Panasonic FR and FC, as the nichicon inside are prone to leaking (same series and period as the big leaky mainboard caps epidemic).

Google for 'retrobrite'. Supposed to do the biz, though I haven't tried it myself. It seems the yellowing arises from the presence of brominated flame retardants in the plastics of that vintage, and is reversible.

The Yaesu is definitely a lot of radio.  It has about the fastest autotuner I have ever seen in a radio and it constantly retunes as I scan the bands.  It even has that newfangled DSP stuff in it :-DD.  I am still getting used to the receive audio.  It sounds much different than the Kenwood.  Not better or worse, just different.  I am still of the opinion that no ham radio gear has receive audio as good as the more vintage Kenwoods.  I love the audio out of my TS-940 and also enjoyed the audio out of the TS-850.  What's funny about the whole thing is my friend is a diehard Yaesu guy.  Everything he owns is Yaesu except for the Kenwood because it does what he needs better :-+ :-+

It is a good radio.
I am not that big of a fan when it comes to DSP, especially early DSP. I have an Icom IC-756 (non pro) and even with the noise reduction shut off when listening on SSB / CW / RTTY the fourth IF is all digital and the sound of the background noise is like someone dragging sand paper through one's ears. I have had the same experience listening to a K-3 it just seems to be something related to the technology. On the other hand I don't have the same problem with my Softrock SDR receiver.

Title: Re: What did you buy today? Post your latest purchase!
Post by: GreyWoolfe on July 25, 2015, 02:54:12 am
I am with you on the DSP.  It isn't turned on in the Yaesu and I probably won't.  I have listened to/used more modern DSP radios and I do find the sound somewhat unpleasant, tinny even.  I do have some mid and high range hearing loss in both ears so there are sounds that bother me more than my wife, who tends to look at me funny when I say something about it or I can't hardly hear them in the first place.  That is why I really like the Kenwood 940.  No DSP artifacts, no crap, just good clean audio.  The Yaesu is almost ready for prime time.  My headset adaptor is in, I just have to go to Radio Shack for a phono plug as that is how the PTT is done in the back of the radio.  Once the foot pedal is wired up, I can give the microphone back to my friend.  I have been using headset/boom mics for so long now, using a mic felt weird.

The newer gear does seem to have less of that harsh audio quality.
I have a friend who has an FTDX5000 and the noise reduction seems to work better than on my IC-756. Most likely the difference between a $2300 radio back in the late 90's and a $6000 radio that is still in production.

Next month the plan is to get one of these to improve reception here.
I have noise issues at this location and I think this will help.
 http://www.dxengineering.com/parts/pxl-rf-pro-1b (http://www.dxengineering.com/parts/pxl-rf-pro-1b)
I also have a Timewave ANC-4 which worked great until i moved my main antenna and the sense antenna was rendered useless.
Looking forward to knocking 12-18DB off my man made noise level.

Before I show what I bought today, a follow up on the Kenwood R-2000. The LED retrofit looks great, and the radio works really well. I'm very pleased with this retro find.

Now, what I got today is really nice. It's a Drake SSR-1, which uses a Wadley loop circuit to generate 1 MHz harmonics to cover all the shortwave bands in 1 MHz steps. This radio worked when turned on, and picked up WWV on 10 MHz with no problem with the built-in telescoping antenna. But what amazed me is the condition of this radio. Many radios this old (like the Kenwood) had bulbs that burned out by now - this radio has two bulbs and both are working. They could have been replaced but I'm not sure it's ever been opened.

You know the plastic protective covering that they put on aluminum? Well there was still some unpeeled parts behind a couple of knobs. When I took the cover off it just had that look of never having been mucked with. It has a battery holder too for D cells that is pristine. I wonder where this thing has been sitting all these years? I'm really excited about this find and I'll be taking it apart to do a very clean cosmetic makeover. One problen is that is smells a little of nicotine, but I can take care of that.

I'll post some pics in the ham radio thread.  :)

Nice SSR-1 The wadley synthesizer is not a loop there is no feedback.
It is however a very ingenious design. Even Wikipedia gets that wrong, which is no surprise.
I have repaired Drake SSR-1s before and I am a happy owner of a Yaesu FRG-7.

No feedback, just mixing and remixing of the high frequency first local oscillator.

Make sure that the wheels are in good condition, and when you modify it add a small length of chain
( if not present already) on the back non turning wheel so that 2 links can dangle on the ground to avoid static build up.

Depending on the trolley ( 2 basket only or the larger type with a steel mesh basket) you might want to make a top wooden cover, and cut a hole in the mesh for access when it is on.

Small trolleys you want to make the basket frame level, most are sloped and things will slide off.

No, I bought the trolleys I modified, from the local shelving supplier.........

I did make some trolleys for work, but they complained about the cost. They have outlasted the cheap ones though, those cheapies all were scrapped after breaking. The ones I made from angle iron, and which were hot dip galvanised, are all still in daily use.

It was a fun kit to build, I have the transceiver kit started but have been too busy to get back to it. (all boxed up and the printed manual in the book case). It works okay, the receiver does about a microvolt for 6DB SNNR, It is certainly usable. It wasn't a hard kit to build although, if your eyesight is worse than my eyesight (20/300) you might want to get someone to build it for you. :) A lot different than that Heath SB-301 I built back in 72.

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=163508;image)

That right there is more than 5 pounds of genuine new, used, shiny filthy knobs, folks!

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=163510;image)

After a bit of sorting, I had a sandwich bag of nasty cheap friction-fit knobs, a little pile of loose set screws and this expanse of vintage industrial design.

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=163512;image)

A number of them are pretty distinctive and I'm curious about their origin. I think I need to start a thread for help IDing them.

In the long run, I'll probably sell or give away most of them. I'd hoped there were a few silver anodized aluminum knobs in the lot that would be suitable replacements for some missing or sub-par knobs on my power designs PSUs, but no such luck.

Not with these no. I do know that the guy next door has told him that he is going to invite the local traveller community round one day for coffee and to see his lovely car park.

Well, I bought it last weekend, and it arrived yesterday.
That right there is more than 5 pounds of genuine new, used, shiny filthy knobs, folks!
After a bit of sorting, I had a sandwich bag of nasty cheap friction-fit knobs, a little pile of loose set screws and this expanse of vintage industrial design.

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=163512;image)

A number of them are pretty distinctive and I'm curious about their origin. I think I need to start a thread for help IDing them.

In the long run, I'll probably sell or give away most of them. I'd hoped there were a few silver anodized aluminum knobs in the lot that would be suitable replacements for some missing or sub-par knobs on my power designs PSUs, but no such luck.

Lot of vintage audio knobs there, I recognise a lot of Technics knobs in the pile.

I am not crazy about those scope meters, but for $45 I don't think anyone could pass that up, rather nice!  I didn't even think you could get one of those for 10x that.

How about free? I got a Fluke 123 handed to me a few months ago. I paid $65 for a new keyboard flex and $12 to get the battery pack rebuilt. It works great.

It's not a buy but a barter.  I was at the local surplus store and bartered a rather large amount of components and parts, including about a 1000 medium sized NOS rocker switches, that were given me into a Metcal MX500P-11, Talon tweezers and a stand for the tweezers.  Owner made it an even swap.  I am usually the one saying. "Why can't I ever get deals like that."  Now, I finally did.  Just tested it and it works fine business. :-+ :-+

NEW replacement iron: Easybraid Shp-1 (http://www.ebay.com/itm/New-Easybraid-Shp-1-Replaces-Metcal-Mx-Rm3E-Or-Mx-H1-Av-Mx500-Mx5000-/171874967486?hash=item28048bdfbe) (replaces Metcal MX-RM3E; this or MX-RM3E usually run ~$100 on the street). Good deal if you can grab one before the seller runs out.

Stands: MX-WS4 (discontinued), current WS1 (https://www.all-spec.com/products/WS1.html), or Thermaltronics SHH-5 (http://www.ebay.com/itm/NEW-Thermaltronics-SHH-5-replaces-Metcal-WS-1-Solder-Auto-Sleeper-Workstand-/351348500106?pt=LH_DefaultDomain_0&hash=item51ce00a68a) (new, either runs ~$65). Or if you've something laying around (i.e. metal coil type), you could figure out how to add a pair of magnets to enable the auto-setback/sleep feature.  :-/O I'd even see if the SHP-1/RM3E fits the Hakko 936's stand.   ;D

And then there's ye olde coffee cup...   :wtf:   >:D Hint, hint: $60 & a tip = you're off to the races (time to start a donation fund or crowd fund?).  :popcorn:

No, actually, this is a new store in New Smyrna Beach, the next town over from me called Planet Surplus.  Definitely reminds one of that particular store. :-DD  Doing some further checking, I found a problem with the second RF connector.  I am going to start a new thread in the repair section.  At least channel 1 works fine.

  After waiting at least a month on backorder, finally able to order one of these. Due Saturday.

 Simply a nice general purpose bluetooth serial link. It's ability to pass on a 'reset' DTR signal (actually it's just a general purpose digital output pin under PC user's COM channel control.

 Used with an arduino type board this output pin can force a reset condition on the micro allowing the bootloader to activate for wireless 'sketch' downloads. Now your mobile robot can have it's brain reloaded wirelessly on the run.

I wonder if Windows 10 upgrade will be compatible with? Hope for the best.

I haven't tested it for accuracy, but it seems to be pretty consistent between the two thermocouples. If you take them together they are generally less than +/-0.2 counts away from each other, generally about 0.1 count away.
I will post a quick teardown, along with the current consumption when I get home on the weekend.

Not sure if this is of interest, but I got one of these 3d printers:

Its actually pretty good, I had already built a 3d printer but it was a bit of a DIY nightmare to keep it running.
This one worked out of the box (took about 4 or 5 hours to put it together and will take another few hours to tidy up all of the cabling etc)

Of course as soon as I pushed the buy button I found this one which looks a little better made and is slightly cheaper. doh!

HP 5371A Frequency and Time Interval Analyzer w/ two 54003A from Fleabay for $200.00 + $49.74 Shipping.  I've got some FE5680 Rb Standards, a NTBW50AA GPSTM, and (recently thanks to the forum), a Lucent RFTG-u REF0, REF1 package. When I started, it was easy - the Rb was correct  :). But then I got a second Rb and suddenly I no longer knew what time it was  :-//. So I picked up the NTBW50 to resolve the issue....  well that just made things worse |O.  Probably what I need is another GPSDO to finally clear all this up  :palm:. When the recent thread on precision timing references popped up I scored the Lucent RTFG setup for $100 (Shortly after they jumped up to $200 then a little while later they dropped it to $150.00. Glad I scored it @ $100). I finally concluded that the more precision clocks I have the less certain I am about what the correct time is.  So, now I'm hoping that purchasing the 5371a will provide the ability to finally resolve my personal dilemma of what time is it :phew:.

New Megger UK 13A earth loop test lead for my Fluke multi function installation tester. 

The genuine Fluke test cable supplied with the meter for this are rubbish as there is no cord grip where the cable enters the 4mm banana plug so the wires shear off from the pins with day to day use. This time it was the N phase that broke away and was left sailing around in the breeze with exposed wire at the end. Conveniently much like toast landing butter side down the cables breaking off tends to happen when the test lead is connected to the mains. There not cheap cables and there is no way to easily check them for damage at the connectors. The only way is to check the conductivity of the cable when it is new then periodically check it against this result in the hope of noticing rising continuity as the wire strands starting to break in the connectors.   

So this time I found the Megger equivalent test lead "RS part number 255-623" which I have to say I already prefer. There appears to be a more secure fixing on the banana plugs and although on their web site it showed strait 4mm connectors it was supplied with right angle 4mm connectors which in use I find to be less cumbersome as they don't stick out so far getting caught on things. At £36 + 20% sales tax there still a relatively costly cable but cheeped than the last Fluke cable which was over £50.

HP 5371A Frequency and Time Interval Analyzer w/ two 54003A from Fleabay for $200.00 + $49.74 Shipping.  I've got some FE5680 Rb Standards, a NTBW50AA GPSTM, and (recently thanks to the forum), a Lucent RFTG-u REF0, REF1 package. When I started, it was easy - the Rb was correct  :). But then I got a second Rb and suddenly I no longer knew what time it was  :-//. So I picked up the NTBW50 to resolve the issue....  well that just made things worse |O.  Probably what I need is another GPSDO to finally clear all this up  :palm:. When the recent thread on precision timing references popped up I scored the Lucent RTFG setup for $100 (Shortly after they jumped up to $200 then a little while later they dropped it to $150.00. Glad I scored it @ $100). I finally concluded that the more precision clocks I have the less certain I am about what the correct time is.  So, now I'm hoping that purchasing the 5371a will provide the ability to finally resolve my personal dilemma of what time is it :phew:.

Special thanks to Ed Palmer for afflicting me with this nonsensical pursuit of determining when it's time to feed the cat aka Timenut  8). You Voltnuts stay the hell away from me  ;D.

Hi Marc,

I haven't been ignoring you. I haven't been following this thread so it's just plain luck that I saw your message.

You're more than welcome regarding the Time-Nuts infection.  Happy to oblige!   >:D

You really think that the 5371A will satisfy your growing lust for ever more precise measurement of time & frequency?  How quaint.  I remember back when my 5372A was the most sophisticated piece of equipment I had.  I couldn't believe that I would ever need (or be able to afford!) anything better.  Now I rarely turn the thing on.  After all, it has a resolution of only 150 ps!  Hardly worth mentioning.

I'm kidding, but only partially.  Time-Nuts is something of an addiction.  You're always pushing for a better source or better measurement capability.  It's fascinating to realize that you can make measurements at the parts-per-trillion range in your basement, attic, or garage.  Right now I'm doing a data run on a 10 MHz precision oscillator.  It looks like it's daily aging rate will be around 4e-11 per day, i.e. 0.0004 Hz per day.

Regarding your 5371A, you might consider picking up one or two 54002A modules.  They're 50 ohm which makes it an easy connection to most test equipment and oscillators.  Just be patient and don't pay a lot of money for them.  The only thing inside them is one little 5% resistor.  Also, notice that the 54003A modules have an input capacitance of only 10 pf.  Many scope probes can't compensate a value that low.  Finally, open up all your pods and check the soldering between the external contacts and the circuit board.  They tend to fail with age.

Ed

P.S.  I see that you chose an appropriate avatar!

That's a great idea.  I'm not sure it would be worth it though.  The PC only has a 10baseT networking card installed and I don't really want to sink any money into this unit.  I'm probably going to end up parting it out and giving the rest to the local technical college.  Amazingly, it still has the original ATX power supply inside and it's still in regulation.

My companies Hakko 808 motor died last week (we have two 808, both suffered the same fate) - we just received a FR-300 to replace it. I had to adjust my ghetto stand for the slight change in shape, happy it still works cause my bench space is currently limited so I can't have it lying down anywhere.

I also recently bought for myself the JBC DME, T245 and PA120

Bought: bluetooth RGB LED controller.
Given: Huawei Android phone.  (Has cracked glass, but works fine. Is why it was free. More free phones coming.)
Still in post: reel of RGB LED strip.

Objective: see if I can teach myself Android App development, including Bluetooth control. Also a redesign of the RGB board and firmware. First actual code & hardware project for a looooong time.

Why: Partly for my microscope illuminator project. http://everist.org/NobLog/20150628_LED_lighting_mk3.htm (http://everist.org/NobLog/20150628_LED_lighting_mk3.htm)
Partly because the Bluetooth controller module would be nicer if it was reimplemented for LiPo battery operation as well as plugpacks. This unit is designed for only running off a plugpack, and would run LiPos down to well below their damage threshold. Also the drive outputs assume current limiting resistors on the LEDs and appear to implement color control via mark-space, so an alternate current drive output would be nice. Especially for the higher power microscope lights.

When: No particular schedule. Though I'm guessing it won't be quick.

I went on a journey with the neighbour and we ended up going to a couple of local recycle centres, at the first one I picked up a Testra T800 corded phone with nice big buttons and a huge lcd display, virtually brand new in the box but when I got it home and after wiping it down with ipa I found that the handset speaker is a bit dodgy so it's in bits until the morning, everything else works fine and I haggled with the staff member but she was adamant and keen to see me part with some cash so I ended up giving her 10 bucks.

At the other centre I found a Teco FM50 VFD not in bad condition and wait for it..........4 bucks, so I will do a quick teardown and take some pictures in the morning and come back and post them here.

At the same place they were clearing out denim jeans, work pants and shorts, name brands such as Lee, Levis, King Gee and others so I loaded up and wait for it .........a dollar each.

Just received a nice Keithley 2000 in the post from Israel (no not the famous seller of insanely priced HAMAS calibrated scrap instruments  ;D). Seller sold it as spare parts / repairs as didn't know how to test. It's working near perfectly and has a nicer VFD than my Keithley 2015, no slightly dull segments at all. Better calibration too  :-+ (well its dated 2013 vs 2003 and DC is near as spot on with my Hao Qi Xin).

(http://i.imgur.com/pQ2MPkk.jpg?1)

I say working near perfectly as its only fault on self test is ACV error 402.2 which is documented in the repair manual.

Looking inside everything is nice and clean, no leaking caps or signs of repairs other than the Keithley green wire bodge on the MCU. One case screw had a seal over it that hadn't been touched either.

I bought it as a cheap scrap fixer upper but this is much better than I expected  :-+ Old firmware A06 will be upgraded soon.  :)

Go and keep a lookout for a nice Keithley. You can use it to recal your 3478A after the battery dies   :-+ (of course it would be more sensible to just replace the battery while keeping the VBAT supply powered by a PSU but that doesn't give you the excuse for an essential purchase does it ;) )

Plenty available on eBay from Japanese sellers (here (http://www.ebay.com/sch/i.html?_odkw=der+ee+de-5000&_sop=15&_mPrRngCbx=1&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xder+ee+de-5000+lcr.TRS0&_nkw=der+ee+de-5000+lcr&_sacat=0)).  :-+

I got a full kit for ~$165 shipped EMS (TL-21, TL-22, and TL-23 test fixtures/leads, AC/DC power adapter, and USB interface). The box even arrived in pristine condition, and others have posted similar reports. If you want just a bare meter, you can get one shipped for ~$93, and one with the 3 test fixtures for ~$121 (both shipped).

The Keysight OTOH, is $437 for the U1733C (bare meter) and $574 for the U1733P (kit). Datasheet (http://www.farnell.com/datasheets/1843842.pdf).

Similar specs & features at less than half the cost for the DE-5000, so definitely the value leader here.  ;D

If I buy something that cost about U$170, to my taxes, it would end up to about US$180 at my credit card bill(one tax called IOF) + US$102 import taxes + some US$20 fixed handling taxes for imports. That give me US$302 vs US$375.
I've bought here, in stock, with warranties easier...

Other country maybe I would went for a different option...

Plus, here, if I do not choose some courier (UPS, DHL or FEDEX or similar) the shipping took about 2 to 3 months to arrive in my house (customs delays), and a big chance that the package never reach to me... :(

Plenty available on eBay from Japanese sellers (here (http://www.ebay.com/sch/i.html?_odkw=der+ee+de-5000&_sop=15&_mPrRngCbx=1&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xder+ee+de-5000+lcr.TRS0&_nkw=der+ee+de-5000+lcr&_sacat=0)).  :-+

I got a full kit for ~$165 shipped EMS (TL-21, TL-22, and TL-23 test fixtures/leads, AC/DC power adapter, and USB interface). The box even arrived in pristine condition, and others have posted similar reports. If you want just a bare meter, you can get one shipped for ~$93, and one with the 3 test fixtures for ~$121 (both shipped).

The Keysight OTOH, is $437 for the U1733C (bare meter) and $574 for the U1733P (kit). Datasheet (http://www.farnell.com/datasheets/1843842.pdf).

Similar specs & features at less than half the cost for the DE-5000, so definitely the value leader here.  ;D
Thanks;
I'll give that some very serious thought.

Whaaaat? Your government is crazy??? 60% tax???

Yes, brazilian customs love to apply taxes on everything citizens import.

They also create an inspection point side by side the chinese customs to control, right on the starting point, all the packages going to Brazil  :o

I'm affraid that this is the next step of the portuguese customs as well... At least I could buy from EU without paying more taxes, but that's a shame.

Probably more, because I never remember all the tax... As I said, they will tax 6% on the buy, and then all the import taxes... All the taxes with the shipping include, and I forgot, after all this, I have to pay another that is 18% (over that final price with all the other taxes) more for the 'local' state. I is very crazy....

Not a purchase but I've just been given a box full of Amiga 600s and 1200s, 2 Atari STEs and a Falcon.

Just a little update, they raised just over £5k and the full auction raised over £35k. The proceeds will be used to buy toys, consoles and games for the 2 local large specialist children's wards and the local children's hospice :(

Not exactly purchases, since everything was free. Recently I had a quite a good day. I'd arranged with an old friend whose health is declining, to drive him from Manly up to Morriset to pick something up. On the way back, in Manly we came across an old Subaru abandoned in the street. Council 'abandoned car, will be removed' stickers, one smashed window, being used by locals as a junk dumping container, has been there for months, etc. Thing is, it's almost identical to my car - 1993 Subaru 4WD station wagon, that I like a lot. Except for the part where the engine needs reconditioning, but I can't afford it. Now extraordinary luck steps in. As I was standing next to the abandoned car, peering in a rear window (it was dusk, light fading) a young guy riding by on a pushbike noticed me. Stopped, and the first thing he said was "Hi, are you interested in that? Do you want the key?"

Ha ha ha... of course I said yes. Turned out it had been owned by a friend of theirs (flat just up the road) who'd been in Oz as a tourist, bought and used the car for a trip up the coast, then went back home overseas. Abandoning the car and leaving the key with his friends. Who weren't into car ownership, and let the rego lapse. So... it's mine now.
Turns out the engine is in great condition, may even have been recently reconditioned. It's identical to my car's engine, exact same class number, swapping is no problem. Even getting the car from Manly to Bankstown area the next day was easy and free. 1st pic is the two side by side (my old one closest.) Given how much I hate cars with engine management computers, and these Subarus were one of the last models ever made without, this is really excellent.

Second windfall: my friend has a long career as a designer of pentium system boards and related stuff. He feels he's unlikely to do any more of that, and is currently living in a small place. After the Morriset drive he gave me a stack of his old tech texts. See 2nd pic. Some of the ones on the left I already have. Anyway, if he does need them again he can get them back. Donating to the TerraHertz tech-archive is better than binning them.

Naturally, the one topic I need texts on atm (Bluetooth) is not among them.

Nice score, you have spares for all the expensive Subaru parts now.  With the books i doubt anybody is designing ISA bus parts nowdays, except for industrial use where they want to shoehorn a new CPU module into an old ISA backplane to control older plant. Just means a CPU will spend more time in an idle loop than the old 386/486 CPU used to do.

Yep. Starting with the rear hatch gas struts, which are near-new on this car. On mine they are original and completely stuffed. Which I have been coping with via a prop.   Also the great benefit of having two engine-gearbox sets, so being able to work on one while the car is running with the other. It was really tempting to swap both the engine and body, if you know what I mean. Like the axe and handle tale. But no...

Ha ha... I know they are mostly obsolete. The interest is historical only for almost all of them. "Windows programming" shudder. Encountering the horrors of windows programming was one of the reasons I quit software mostly, and concentrated on hardware & low level embedded.
I did some ISA cards long ago and one or two plain PCI cards. No PCI express or any other of the high speed differential pairs buses. Last ISA and PCI cards I did in pic. ISA card was in 2001, I forget when the PCI sound card was.
Gray blocks are to obscure company details. Not that I owe them any favors, but I'd like to reserve the right to insult that employer anonymously.

I will bet they simply took the Crystal audio drivers and did a simple change of name inside the inf files, and probably never updated the driver after that release....... Nice little meander on the clock line though, you must have needed those few extra ns of delay.

Both these boards were for use in equipment made by that company, in a highly red-tape regulated application that required all code to be submitted to a regulatory authority. Once approved, there was no way anything was going to get updated anyway. Just being allowed to submit binary blobs like driver files was a major battle.
The meander length was as recommended in the reference design from Crystal.
The only special thing about that audio card was the grunty output amplifier. We couldn't find any audio card with an amplifier included. For our application we needed it built in.

I once got a box big enough to for me to fit inside it, that had 48 smaller boxes in which each contained a piece of paper with a licence number on, that they had already pre-loaded on to the devices I'd ordered

Not cheap!? Wow! I make that £100 + all the import tax £20 + £13.50 parcelfarce fee!

It's cute, but its just the same thing as we all make from the ebay 10 pack of cheap click switches. My own, I used 1/4W resistors on the ranges except for the 10 and 1 ohm ranges, 1/2W still fit those switches and mean you can still use them with a realistic low voltage. Making it myself I also have the ability to pick the best 1% resistors to be within tolerance by 0.1% or more.

One thing though - out of the 10 switches I think maybe 2 or 3 seperate switch banks of decades are better - like a 9.999k bank, a 99.9k and a 9.99M - because all the lower decades become meaningless despite how accurate they are when the higher ohm decades have to be 0.0001% accurate to follow suit.

Also, 3 resistor boxes are better than 1  :-+

Regarding the people watching, perhaps:
Waiting on funds?
Undecided if they're going to buy at all?
Reminder of some sort (maybe in the form of an attached note)?
Waiting for more feedback for that particular seller?

Whatever the reason, placing it in their watched list makes it easier to find later.  :P

Back in the day,we used "Scope" brand "instant heat" irons.
They had a carbon element which contacted the tip when you pressed the control ring,so were normally cold.

To check if the iron was heating,it was common to hold it near your face so you could feel the heat.
On one occasion,I misjudged & touched the tip of my nose with the tip of the iron.

It really made my eyes water! ;D

Heat up time should be easy to measure, just use ya tongue like the battery test.

Back in the day,we used "Scope" brand "instant heat" irons.
They had a carbon element which contacted the tip when you pressed the control ring,so were normally cold.

To check if the iron was heating,it was common to hold it near your face so you could feel the heat.
On one occasion,I misjudged & touched the tip of my nose with the tip of the iron.

It really made my eyes water! ;D

Death, maybe I will try to test a battery and soldering iron tip with my tongue at the same time :-DD

I have also held soldering irons close to my face to feel if it is getting hot.  I did it recently when I bartered for my used Metcal with Talon tweezers-they got hot pretty quick.  Haven't burned my face yet but that is what Silvadene is for :-+.  They way I look at it is that the iron cauterizes the wound for you and those scars do fade unlike all the cut scars that still show on my hands.

I have been looking for a small bench power supply and stumbled upon these on eBay. 
I remember using them when I was in school.  Ah, the memories.
That does bring back memories.
Also used them in school.

Good score.

Another DS1054Z here.  £282 incl. VAT from Telonic, placed the order yesterday and it turned up at 9 this morning.

Took 5 minutes to apply the firmware hack, now it's a DS1104Z with all the options enabled... I'd quite like the carry bag for it (this scope saves me having to remove my other scopes from the bench shelf) - but not at £49.20 - anyone found a cheaper carry case?

You can have this one, but isn't much cheaper: http://www.ebay.com/itm/RIGOL-BORSA-per-la-serie-DS1000-DS1000-series-SOFT-CARRYING-CASE-/121740229128?hash=item1c58487a08 (http://www.ebay.com/itm/RIGOL-BORSA-per-la-serie-DS1000-DS1000-series-SOFT-CARRYING-CASE-/121740229128?hash=item1c58487a08)

Plus some other things, like screen protectors for the phone, some SMD practise boards for the Ham club ( next month start the fun of people trying to assemble them, I will have to do one myself just to have the sample board)and some LEd driver boards.

 I used to have a PDF but I seem to have misplaced that file. I felt I had to buy the book anyway and since it appearantly was on sale I had no excuse to to buy it. IMHO one of the better books on implementing circuits using microstriplines. Lot's of down to earth formulas.

That's the one they included for free back when I bought my DS1052E from them. It's well padded and seems sturdily constructed. Mine has a kind of vinyl lining instead of cloth which I don't like, but it's okay for the price ("free").

Good deal..
I don't use a touch screen or use it in tablet mode.
I may in the future since I want to pick up a tablet to put manuals for gear on.

Running Windows 10 on my 2-in-1 for a while, so far no big problems. Still, I do prefer Windows 7 Aero theme better than Windows 10 themes, and is therefore I won't install Windows 10 on my working computer in the short future. Speed wise, both are great and fast, but Windows 7 seems to be more responsive, while Windows 10 is claimed to be more efficient, despite I've never felt it.
I admit I miss Aeroglass.

Found this quality item in a local import bargain shop whilst picking up some other novelty gadgets, got it out to the car for further inspection and low and behold I found that it has a "take it apart" feature already incorporated as a bonus, it fell apart in my hand.

I then went home and plugged it into mains 240 volt and it worked, the lamps indicated power, I then turned off the mains and went to pull out the probes from the power point and the probe tip remained in the power point whist the probe cover separated exposing the damned user to the dodgy connection.

Will be heading back to the shop tomorrow to warn them to stop selling this shit before someone gets killed, keeping this one for evidence in case they refuse, I'm sure that the relevant authority will be keen to investigate not only this shop but others as well.

How much I hear you ask, 2 bucks and as many as you want.... :palm:

Keep Safe.

which are 1Kx64 content-addressable memories, they get used for database searches and in routers.

I don't really know what I'm going to use them for yet, but content-addressable RAM is a really cool idea so I'll think of something.
Also picked up a pile of FIFO ram, which will hopefully transform into some kind of inter-CPU comms thing.

Initially I thought it was coming in throughout the front end of the LNA, but now am pretty sure it is coming back up the receive line (from the transceiver receive port to the feed horn LNA). Despite the loss of magic smoke, when repaired,I am happy I  am still getting a noise figure of ~0.3dB gain of 35dB at 1296MHz.

I know this won't be very good but for £15 I couldn't resist, I mean who doesn't love Bakon?

Kidding aside though I'm going to test how it compares to a FX951 with the supplied tip and with a genuine T15 tip, I'll just be waiting on something to test the temps with. After that it's going to be modded to be part of a portalab lol.

Those are very nice and very cheap, the problem is that they don't have any DTR pin to program atmegas :(
I've come to the conclusion that chinese sellers simply put "arduino" on the description line now, just to get the views.

for less than $10, its a usb OTG micro sd card reader.  cool part is that the sd card inserts right INTO the usb connector.  quite a trick ;)

testing with 128gb card seems ok.  planned use is to transfer data from pc to phone (recent phones support on-the-go usb).

not expensive, not a big deal but cute and useful.

I bought 20 of these about two years ago and now have run out.  Use them for filters and little function generators and the like.  They solder up to the edge on a PCB or proto-board, at least the proto boards that I use, and are super convenient and compact.  Graduated to the big-boy package:

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=174749;image)

I buy these by the thousand for production, they work out at $0.20ea. I also use male versions for inline prototyping filters. I'm not sure how well they work beyond a couple of GHz but for the application I have them in they are fine.

I visited the new local surplus store today and grabbed 2 HP LP2275w 22" LCD monitors and 2 VGA to DVI adapters for $91 USD with tax.  One had minor scratches on the screen that aren't visible when the monitor is on. Both have no dead pixels and are nice and bright.   I had a 22" and a 19" LED monitor on this computer but the 19" has gone to the spares shelf and the 22" LED has replaced a 17" on my workbench.  It is nice to finally have matching sized monitors on this computer.

I just bought a brand new scope for $17. To be precise, it is a USB endoscope or inspection camera. I do not have a particular use for it yet, other than tried to look into my ear for the 1st time in my life. It may be a useful tool when some small parts dropped in some hard to reach places.

The cheaper ones goes for about $5 each on Ebay. I picked this one because it advertised for 1280x720 resolution, Android support and 5.5mm in diameter, though the captured image does not look like with a resolution of 1280x720 and as expected, the image quality is not that good. And also the Android part did not work for me. The imager is a GenesysLogic IC(?).

The 1st picture is the camera head.

The 2nd picture is a captured image by this camera. It was taken about 2" away from the paper. 2" is about the distance having the best focus.

a USB endoscope or inspection camera.

I found with the 10mm dia one I bought a while ago, a small lens from a CROM drive head can be blu-tak'd to the end, to make quite a workable improvised inspection microscope.

Though  I never did find any other use for it. Even with a stiff iron wire taped to the lead to allow bending to suit, it's not much good for building cavity inspections, threading cables through difficult spaces, etc, since the LED illumination and depth of view are too small. You see either nothing, or some inscrutable closeup of wood or gyprock.

The 8640B arrived today.  In addition to option 001 (audio oscillator), I was pleasantly surprised to find it also has options 002 - an internal doubler that extends the output range from 512 to 1024 MHz, and 003 - reverse power protection.  I haven't tried to power it on and begin troubleshooting yet, but my fingers are crossed that the no output issue that it was listed under winds up being a relatively minor thing.  I'm on the hunt for a hardcopy of the service manual now; hopefully one will turn up soon.

Something rare I've been hunting for literally years.
A General Radio GR900-LZ6 Coaxial Reference Air Line (6 cm)
I have a GR900 slotted line, and the set of reference air lines, but this one part was missing. Finally one turned up by itself.
It's in the post from USA to OZ, so will take a while.

US $60 plus about $20 postage total (via reshipper), so probably the most expensive very small piece of metal pipe I've ever bought.

I have one of these, and as a magnifier & lamp it is basically OK. I made my own mounting base for it, as the standard one got in the way of the cupboard next to my bench, and a trick I used was to wrap PTFE thread tape around the swivelly bit of the arm to increase the diameter to the point that it just made a firm fit into the base. Stops it swinging about in the breeze, but still easy to move.

A small but attitude altering addition to the workbench.

This $4 device takes the angst out of repeatedly opening and closing the jaws of a Panavise 201 or 203 jaw vice. Just snap it onto the vice wingnut, insert index finger and spin. Stand back and watch the smiles appear.

Best $4 I have spent to date!

A nice little DIN rail mounting power meter.  Took it apart before turning it on, and aside from the 3 internal IC's being the ground off top type ( one is obviously a PIC doing the math and display side, one is a jellybean quad opamp and the last os likely a cheap ADC, so no surprise there) it is not bad, input power being provided by a capacitive divider, and with voltage sensing using 2 series 100k 0.3W 1% metal film resistors.

All in all it does what it needs, and $25 with "free shipping" was not too bad.

Shown testing it's own power draw. 10VA, 3.2W and a really bad power factor. PF does not seem to have a magnitude, it reads the same irrespective of direction of current flow through the internal sense coil. Still, goes from 0-100A and should do the job.

Most of them were just yet more Fluke 25s. I've got loads in stock, but usually sell a couple a week so more is always good.

There are also half a dozen Solartron 7150 6.5 digit meters. I'm hoping that they work, but at least there is a decent manual available for them so should be a fun fix if they do have problems.

These have an inherent fault that means it isnt going to last long, the base spigot is a tube that has been cut half way through, bend it a bit and its game over as the lamp will flop on the ground.

I got the usual and very fine tequipment discount!  it is my first signal gen, but I am very pleased for the money so far.

:)  I have a feeling that Siglent's misstep will be forgiven when people see the value this unit has.  I think the SDG2042X could very well become the "DS1052E" of its time in terms of bang for the buck in siggens.

Why are there three lead jacks? But only two leads? Could it be they used a standard multimeter case, only changing the printing?

Cheaper to use an existing mould set ( no cost for tooling, and they only have to pay for a new screen for the printing) and the case already had all the cutouts aside from the one they had to make a jig to drill out the zero adjust knob. Jig would be a drill press and a wooden set of angles that they place the meter top in and bring the drill down. I made a similar one to do larger punch holes in some card backing boards, as the supplier made them 1mm too small, and the new posts we had were too tight a fit. We were not going to throw away 10k of boards, so took a cheap drill press and bought a 1/4in hole bit to drill them out. Took a week to do the lot in spare moments.

UA6013L. What a bizarre meter. Does it have some kind of servo inside to do the "auto range"?  :palm: The 3 probe jacks seem to be split between one that's 200mA fused and one with a max 35VDC? That variable REL feature looks handy  :palm:

I guess it may read high'ish capacitance, though no accuracy specifications so it could read any old rubbish.

I guess the backlight and reading hold are much sought after features, and the little header between to get round those pesky IEC1010 safety rated jack sockets.

That would be stray capacitance causing ghost voltages. The meter must be using this phantom power to try and turn the servo for its auto-ranging.

Yeah, it looks like Uyigao are using the same design for many of their meters:
UA6243L - Digital LCR meter
UA33 multimeter series (B, C, D) (interestingly, there's no A version on the Internet)

Looks like the hole is already on the rest of the meters as a power button... or a torch?  :wtf:

I bought a Uyigao temp gun recently (a few pages ago), the plastics are pretty nice, feels solid. Great device for USD 15 delivered.  :-+

I live IN scouseland and wouldn't have this, but a tear down and review is in order!  ;)

I'm guessing it is at least fast at measuring large capacitors in the mF range?

For a nice cheap excellent little meter with capacitance that actually does autorange go for a UT136B, and when you need another quick fix a week later get the UT136C so you have a temperature probe version too  :-+

Oh and you must have one of the Atmel 328 based "$20 LCR ESR transistor testers" by now? Open source - huge thread on here.

You aren't wrong, I bought one of those insanely cheap Baofeng VHF/UHF handies to see what all the ham fuss was all about. Not a sausage on the airwaves, though I did eventually find a distant repeater some old guy and his mates would appear on every odd sunday. They would discuss who had recently died and their/wifes latest ailments and then a bit of ham tech talk. Bit depressing really  :( I had to resist butting in because I don't have a licence. CB is also dead as a dodo. I was hoping with the no barrier to entry and everyone moving over to mobile phones and IM all the idiots of the 80's/90's would have left.

I upgraded to a 4 port VNA today.  This is the Agilent E5071B 4 port VNA with the touch screen and 1E5 reference oscillator options. I bought it at an online auction and it seems to work fine and it came with a 13.5GHz 4 port Ecal module (pictured) which is a huge bonus.

I'll be spending the next few evenings putting it through its paces to make sure it works OK before it replaces my trusty old HP8714 VNA...

It is a bit odd that it has both USB and floppy but it runs Windows 2000 as its OS and there are three USB ports on it and they have the same functionality as a typical Windows PC. So I use one USB port for the mouse, one for the Ecal unit and the other for a USB memory stick. It also supports PS2 type keyboard and mouse via dedicated sockets for each.

I think some of these VNAs have a removable HDD in place of the floppy allowing removable data storage (for improved security/privacy when it goes for calibration etc?)

We use a USB floppy drive replacement on our Juki pick and place machine and it has worked out great. For us the secret is to skip the custom usb stick format and use only a single image per flash drive instead of the 99 some allow. At that point it is plug and play - and only 1.44mb but that is plenty.

Last week took delivery of a Siglent SDS 1052DL DSO. Now before I hear the cries of “Cheep chit” and “You could have done better” let me explain a few things. I'm just getting back into the hobby after about 15 years of inactivity. I have zero experience with DSO's so I wanted to start “small” and see what they're all about. And I really don't need more than 2 channels and 50MHZ bandwidth (I can get out my big gun Tek 2465 if needed). My impressions?   

What I like: All the menus and figuring out what they do. My simple mind has been entertained all week. The EZ scope software and the interface to the PC (after figuring out that I needed to download and install NI-VISA to make it work). This stuff is pretty cool and I have a lot of catching up to do.

What I don't like: The somewhat noisy trace, even with no cable attached or signal applied. I guess it's a characteristic of the low end. But it's not a big distraction and I can live with it. Overall I'm pleased with my decision.

Sorry, thats Quartus Prime (Lite edition) - it used to be Quartus II (Web edition). You can't program most of the mid or any high tier FPGAs with the freebie, and compiling will only make use of a single CPU core to slow you down. Probably some more restrictions, like the NIOS II soft cpu is the limited version, but I can live with them and save $3000 per year  ;) :-DD

Hmm... I will be surprised if I can't use Quartus to program it. I mean it works with my little £5 EPM240 CPLD board with a clone USB Blaster ok...

Though I have been having problems in Windows 10 with that lately (BSOD's), but it works perfectly in Ubuntu 15.10. I'm guessing the Windows 10 stuff is because I am on dev insider builds + installed some crappy hack libusb stuff to try and get an Olimex JTAG working and it's FUBAR - I need to reinstall Win 10 I think, but Linux works perfectly with this stuff. I just groan at the 3 days of my life it takes to reinstall Windows and all the applications known to mankind...

I didn't buy anything today because the whole country seems to be shut. Normal Sundays in Germany are bad but today is 'Death Sunday' when we are supposed to think about dead people.

It all started early this year when I picked up a Rigol DSA815-TG Spectrum Analyzer so I could tune a duplexer for a repeater I'm working on. It's been non-stop since!

<snip equipment list for brevity>

I think I'm seriously finished for a while.... What the definition of a while is, I'm not sure... I may be suffering from equipmentprocurementitis.

GAS - Gear Acquisition Syndrome - a common malady among photographers, too.

I was doing well with staying off of evilBay for a few weeks, but this morning got a notice about a non-functional HP 3580A 5 Hz - 50 kHz Spectrum Analyzer (turns on, gives a trace, then goes blank - hopefully a power supply issue) that included the operating and service manual for a buy it now price that (especially considering the manual is included) seemed pretty good to me, so I jumped.

I should probably turn off those e-mail notifications, they're the debbil!!

(And I have no SWMBO to moderate my GAS either.  For the time being, I'm ok with that.  My credit card, however, is not as enamored with me)   >:D

I would argue that over time, Gear Acquisition Syndrome will cost me significantly less $$$ then if i had a SWMBO in the house :)

Besides, I like peace and quiet!

LOL - too late for that - SWMBO is gone, and cost a bundle in a home renovation/additions prior to her departure.  On the bright side, there is now more space to store the acquired toys.

This thread makes me appreciate how good I have it. I get to indulge in GAS without restriction as long as SWMBO can indulge in CASAS (clothes and shoe acquisition syndrome) - but she earns as much as I do.

That Keithley 2015 looks to be in pretty good nick! I've been on the hunt for one recently.

I don't know why I just bought an Advantest TR4171 sold as-is. I figure it'll have some educational value as I know absolutely nothing about spectrum analysers.
At the very least, I'll learn to stop buying heavy equipment from overseas, I ain't looking forward to the shipping bill...

I wonder if anyone knows anything about the TR4171, I can't find any manuals online.  :-\

Picked up a Shibasoku 725B distortion analyser! She's a little sick though, I think some of the relays are faulty but I guess it's to be expected after 22 years. This'll keep me busy for a while.

It's the unit on the top, the build quality is breathtaking, have a look at that wiring!

It shows 6% of full scale 0.003% = 0.00018% (~-115dB) THD+N for 2.6Vrms @ 2kHz // 30kHz BW. Considering that its residual is specced <-103dB THD+N, you can tell the engineers didn't pull any punches.

Bread and circuses. I am still waiting to hear from all my baby-mommas that camped outside Tequipment HQ for me... I hope they did well... I think all that xmas equipment I was expecting is going to be smashed to pieces and I won't hear of them until I see them on Jerry Springer or Jeremy Kyle USA.  :palm:

Now I am libertarian at heart, but the likes of the Walton family that fuck up local businesses and then rely on welfare recipients and also paying the bare minimum to their staff (who then rely on government subsidy) to engineer these spectacles for their own amusement and profit because the loss leaders are made up with the saps who are left behind makes me sick. Because they bought ASDA and they are bringing even more of this shit USA culture to the UK  :--

Even outside of the USA there was a Black Friday sale. Did not realise it, and went to do my normal shopping after work, and then found the line to go in, along with the crazy queues. In easy, 10 minutes doing the shopping ( no real reductions, but they had a massive pile of Coke going into trolleys as fast as they brought out the pallets. I did not buy any, just Coke Zero) and then a 40 minute wait in a line to pay for the shopping. The store normally closes at 6PM, but Friday they closed at 10. Suggested to the staff members I know that they needed some Monster energy drink to keep them going, seeing they were working a 15 hour shift.

Boy, I haven't seen anything like this before... If I was a Walmart shop clerk I certainly wouldn't show up without proper riot control gear on that particular day... Amazon started something similar here a few years ago, they call it "Cyber Monday" but it actually takes an entire week and the deals aren't really breathtaking, and, of course, it's an online retailer so you wouldn't risk your life and get stomped into the ground by buying something from them. I bought Adobe Photoshop Elements & Premiere Elements 14, together for ~50€, thought that to be a good price (not on Amazon).  :popcorn:

Honestly,this year is the first time I have heard of "Black Friday" in this context.

Black Friday always has meant any "Friday the Thirteenth".

It also had a specific meaning in Oz,due to the horrific fires  in Victoria in 1939.

Arrived in the post: a few ICs: ssc620 PWM, Low EMI, Auto Standby Low Power Off-line SMPS Primary Switcher. To fix my daughter's PC speaker amp.  Took a while in the post from Hong Kong.
And when it turned out that IC in the amp wasn't faulty after all (it sure had put on a good appearance of being utterly lifeless) a MBR20100CT dual schottky power diode from Jaycar, to replace both the output diodes. One of which was a dead short, and why hadn't I noticed that in the first place? Sigh.

Also: 4 liters each of Acetone and Iso Propyl Alcohol, plus a cable entry for an induction motor I'm restoring.

Technically I bought it a week ago, but it showed up today.  An old HP 1980B scope, sold as 'missing fuse, doesn't power up'.  A replacement fuse and fuseholder cap got it fired up, but there are definitely some issues to be addressed.  Most of the buttons seem unresponsive, and the display is a bit dim and doesn't focus well.  I'm betting on at least filter caps, and who knows what else.  On the good side, there are traces and text displayed.

And what is her language?

@Helix70: Nope, no luck. I tried 5 different bluetooth dongles and internal (laptop) bluetooth, but the Formsview software doesn't recognise any them as valid ports.

Bryce.

Bad luck. Oh well, worth a try!

Got my Fluke 287 today, works great. What a bargain. I ordered my ir3000 FC from RS and got it for 85 bucks AUD. Not bad! Will be here tomorrow.

A WIFI wireless switch named Sonoff from Indiegogo(http://)

Now that reminds me, we used to have wifi wars here, I named my wifi " Johns socks stink" and it went from there, some very interesting names came out.
You can do lots of things with wifi names...  :-DD

I wonder what would be the outcome if you named it something along the lines of " Rosies Pornographic wifi " or even " UK MI5 Secure server -Wales " ........ every wifi nut about would be trying to hack into it, which if you put it on its own server with a single web page that logged up the message "pervert" or such could be fun

Tried some soldering for the first time since I moved into my apartment last night. Let's just say I realized fume extraction was going to be mandatory after the first joint.

So I picked up a Hakko FA430-KIT1. (The kit includes the duct and hood) Little painful in the wallet, but I don't trust the little computer fans and charcoal filter stuff, and good health is worth it.

For serious soldering I'd recommend just venting to the outside through a window using dryer hose and something like a Weller WSA350. I have one setup where the filter and fan in the Weller hood have been removed, then a 4 inch dryer hose is attached to the back and connected to plexiglass with a 4 inch fan mounted to it. I can open the window, sit it in place and then close the window which holds it all in place. It is much nicer to have all of the fumes gone, not just filtered.

Nice one. I had this book some 25+ years ago as I recall. After building my own 6502 based computer system I wanted to build my own 68000 computer system but never got around to it. In fact I was going to use the 68008 to keep the bus size down. :)

I'm out on the left coast this week, and a visit to Apex Electronics up in Sun Valley led to three new additions to my nixie equipment collection - all HP:

The first is a 2402A integrating voltmeter. It has a few empty card slots; I'm hoping these are for options it lacks and not an indication that it's been cannibalized in the past as it is in pretty decent physical condition other than a layer of dust.  Searching online has thus far not revealed much information on it, and Artek doesn't list the manual, so it may require some patience on eBuy to find anything on it.

The second is a 5360A computing counter; it has a 5365A input module and a 5379A time interval plug in.  It too includes a lovely layer of dust.  I haven't yet opened it to peek inside.

The final thing is a 5325B universal counter; it's in the roughest physical shape of the three with some broken and/or mismatched knobs and is filthy dusty inside and out, but at a glance appears to be all there parts-wise.

I haven't yet tried to fire any of them up because of course they all take the old style oval AC power cords, and of course that's no something I carry with me. I'll try to rig up a suicide cord in the next few days and see if I can at least turn them on briefly.

Pictures will follow when I get a chance to take and post them.

You might want to ask for a rebuild kit instead of a new ratchet (current production is made in China).  ;)

Take apart, clean in kerosene, lubricate with some moly grease and put back together and, providing the little springs have not broken, it will do another 30 years.

I do the same with my Gedore ones, and they just carry on working.

I haven't tried to pull it apart yet.  As soon as I can find where I put it so it wouldn't get lost, I will see about taking it apart.  Once I find it I can use the part number on it to see if a rebuild kit is available as a plan B.  It has been a long time since I replaced anything Craftsman that I forgot everything is out of China now.

Once I get them put up, I'll have 18 linear feet of 11 inch deep shelves and 6 feet of 8 inch deep. That should be more than enough. Now I just have to figure out the lighting.

Well, the new place is not much different from the old. There's a link to a post with a photo in #709 above. It's not in a closet, so I'm missing the closet shelf it used to hang from (and a couple of walls). What I need is some kind of bar or rod that could extend from one of the shelves and hold the weight of the scope. Or I guess I could maybe hang it from the ceiling somehow, but that seems kind of kludgy. I really need it to hang though, because at that angle it doesn't stick out so far. If I just sit it on a shelf it hangs over the edge by about 3 inches. I'm inclined to just leave it stored in the closet, I really haven't used it much lately.

You could hang it from beneath lowest of the long shelves, on the right side as you had it before (i.e. between the middle and right most shelf brackets). I'd also recommend drilling through & countersink to be sure the hooks/eyes don't pull out.  ;)

@nanofrog , a 'dodgy brothers' video using webcam in the "shack" re U1282A

Pluses  Long Battery Life
           Good, accurate meter
           Tough as nails, dust/water ingress
           Keysight back-up pretty good
           Quick switch on time
           Quick continuity
           Features +++

Minuses   Big / Heavy
               Cables a bit stiff out of the box, ? may loosen up but it is pretty hot here today, 35C, so I doubt it
               LCD viewing angle  ( I still am a bit of an OLED fan)

Correction to the video, the U1282A read 10.001 (not 10.0001 as I said), the 3458A read 10.00050-something, of note the 5yo U1253B has not been re-calibrated   
       since new

A laptop style SATA-connected optical drive, for a Dell 1U rackmount server. Arrived yesterday.
And wouldn't you know it, the power connector is something so new no one I've asked has seen one before.
Does anyone know where I can find a mating plug? Or what it's called?
Pics: http://everist.org/NobLog/20151112_planning_vacuum.htm#dell (http://everist.org/NobLog/20151112_planning_vacuum.htm#dell)

On the rear the longer connector is the 7 pin SATA. The shorter one next to it is the power, in similar style, but has 6 pins, at a finer spacing, and the keying is a mirror image to SATA.

I just won a broken HP 6114A. For those who remember, I still need to get back to fixing my 6115A.

Is that the 6114 with the 10-turn pot, blurry photos and broken power switch? :-/O
I was bidding on one with a broken switch,and lost. This one appears to be more recent. It piwers on,gives some voltage, then shuts off.

When i was working on my 6115, i realized that it must have caught fire.

Surely the glass fuse holder will also take a BS1362 ceramic? Why even bother. I mean if you aren't working as a linesman and/or at the electricity substation? In which case you would have a Fluke anyway.

Started out wanting to get Tek AM 502 differential pre-amp for some power supply noise testing and for some home electrophysiology experiments.  Offer accepted yesterday on a  decent looking one on eBay (http://www.ebay.com/itm/Tektronix-AM-502-Differential-Amplifier-for-TM500-Mainframe-/262162214436?_trksid=p2047675.l2557&ssPageName=STRK%3AMEBIDX%3AIT&nma=true&si=UDlhYrU0NGlutqXZRBLvu6RpSfQ%253D&orig_cvip=true&rt=nc).

(http://i.ebayimg.com/images/g/vA0AAOSwnipWV3~B/s-l1600.jpg)


Next I needed a power chassis for it. The Tek TM 501s and 502s all seemed too pricey on eBay. For some reason the TM 503s are cheaper.  But the world of classic Tek modules is new to me and - if I was going to have a TM 503 - I would have to have some other modules for it....   So I stumbled upon this one (http://www.ebay.com/itm/TEKTRONIX-TM-503-POWER-MODULE-DD-501-DISPLAY-FG-502-GENERATOR-WIRES-PLUG-ADAPTER-/141503141182?_trksid=p2047675.l2557&ssPageName=STRK%3AMEBIDX%3AIT&nma=true&si=UDlhYrU0NGlutqXZRBLvu6RpSfQ%253D&orig_cvip=true&rt=nc).  Seemed like a great deal with 4 modules included and some cables and connectors to boot! Perhaps I'll sell the FG 501 and one of the DD 501s.

(http://i.ebayimg.com/images/g/eesAAOSwD0lUiLOm/s-l1600.jpg)

I don't really need the function generators and I'm not sure what I'll do with the DD 501s - but if my vintage equipment acquisitions were based on need or logic, my lab would be much emptier.... ::)

True, I'm not, and no, those holders won't take BS1362 without modification.
The stock glass fuse is 5x20mm, BS1362 is 6.3x25.4mm those dimensions are far enough apart that mangling the holders to fit will make them pretty useless.

On the other hand, 5x20mm ceramic fuses are available... easy answer strikes! I just want something that has a good shot of preventing major injury if/when I'm an idiot. I don't trust metallic discharge lamps (sorry, glass fuses) to do that.

And blame Maplin for the Uni-t purchase, needed a vaguely competent meter in a hurry, that was the best they had :( I'll add a fluke 101 to the toolkit sometime.

Some MG Chemicals 413B flux cleaner. Very effective, and despite advertised with plastic corrosive warning, it is compatible with all electronic grade plastic materials I have.
The downside: ether acetate at high concentration smells horribly, so I have to use it not on my work bench, but in a fume hood.

Hey, I bought a can of that stuff about 2 years ago "just in case" and I have never used it.  I use 99.9% isopropyl alcohol for the initial clean with an anti-static toothbrush and then a spray with MG Chemicals 4140.  That works great for me, though sometimes it takes two times thorough to get it perfect (I use Kester 44 which is moderately messy but flows great IMHO).  What does the 413B give you that the 4140 doesn't?  What sort of fluxes or situations do you find yourself using the heavy duty flux remover for?

BTW, 4140 spray is just drinking alcohol plus IPA, with propellant.

That's fine.  The way I use it is to scrub all the crap off with IPA which obviously leaves some IPA with dissolved crap standing on the PCB afterwards.  A couple of shots of the propellant based stuff sends that crap over the edge and then I dry it up with the compressed blaster can, check it out, and either pass it or do it again.  At least, that's how I do it.

More silicone insulated wires:

See for example: www.ebay.com/itm/201345474400 (http://www.ebay.com/itm/201345474400) but this seller has more Ebay items with many sizes and colors.

Silicone wire is very handy for making test wires or wiring which needs to be bend around tight corners. It is much more flexible than standard PVC insulated wiring. Even the 6AWG (16mm^2) stuff is extremely flexible!

128 KB with 4 chips, maybe combine them and make a 65,536 16 bit word buffer. I could serialize 4 fifos easily.

Interesting, I remember the Brompton was the folding bike of choice for city commuters (I assume you will be commuting in by train so need the folding carry design). I never knew mountain bike versions existed, but why?

Those fat knobbly tyres really drag, you are far better going for narrow slicks than typical mountain bike, and all the full suspension is a waste of energy too, though I think you have a hardtail and front forks so they a good for bumping over pavements when you have to go off road in the city.

Yes I have to experiment with tyres and the steering/seat stem length (6'2" tall). The front suspension has a lock out for pavement use. I live in a 3rd floor flat/apartment so needed a fold up to make it easier to carry up the stairs and easier to store indoors. Going to fit the Bionx as the battery and wheels can also be removed easily so the bike can be carried in stages if needed. My commute is 20 miles each way so the aim is to cut out public transport and save money. Can use the bus though as well if an emergency although it will take some experimentation and I'll have to fit it in a bag.

PS. Here are details of an All Wheel Drive (AWD) electric bike using the Paratrooper Pro on Endless Sphere (Just to keep on topic).

You know Raleigh re-released the Chopper recently. But Elf'n'Safety had to get in the way and banned the '70s gear shifter because they thought too many kids could get their knackers knackered so the Sturmey Archer handle bar gear shift would have to make do instead.

This is not a what I bought but what I wanted to buy while think about fun times. I love old vintage stuff. Yesterday I decided to take a ride to the Habitat for humanity store. This store used to be an ice skating rink many years ago when I was just a teen.  They only originally has the area where to concession stand was but mow have to whole building.  Not being able to go into the old ice rink part of the building I was pleased to see they now had it.

As I browsing around I kept seeing images in my mind of the place in my childhood. I could see the now boarded up and painted over window where you rented your skates, the area where the DJ booth used to be. A bit in a daydream I turned and saw something sitting on a shelf.

I went closer and found a B&K 1540 40MHz dual channel oscilloscope with one original probe. This scope looked brand new. Not a spot or scratch on it. No signs of wear what so ever. The only problem, was the $100 dollar price tag he had on it.

The manager of the store walked up and said, Hey, it works as good as it looks. What you think of the price? Being a lover of old scopes I told him it was way more than I would put into it. He sad he checked ebay and that was the price he came up with. I then offered him $50 bucks for it which was still more than I wanted to put in it. He said check back in 30 days. If not sold he let me have it for that.

Wow, that does look brand new.  I'll bet you'll get it for $50.

A couple of years ago my local Goodwill thrift store had a 60MHz BK scope for $9.99.  They apparently were not smart enough to have checked eBay prices.... It's in great shape (not brand new looking but still good) and works perfectly.  They also had a Bel-Merit "all in one" counter, function generator, DMM, power supply with it for sale at $9.99.  It also works fine.  Sometimes you get lucky.

It's in great shape (not brand new looking but still good) and works perfectly.  They also had a Bel-Merit "all in one" counter, function generator, DMM, power supply with it for sale at $9.99.  It also works fine.  Sometimes you get lucky.

Yes, it is a very beautiful piece of test gear. I am just amazed how well it has been kept.

Wow, very nice finds you got.
I found that the thrift store here is way cheaper than the Habitat store is. Like you said I do not think they search for prices. Plus at the good will store everything is given to them while at the H.f.H. store they purchase some items.

Really hope this scope is still there in 30 days.
Thanks for sharing your finds.

The sad thing is in 30 days it will be dirty and/or broken by all the bozos fiddling with it.
Maybe go back in a few days and ask him if he ever sees such a scope sell for $100 on ebay.
Or find some counterexamples of similar scopes listed much cheaper that do sell.

Agreed. I will be there every Friday to see what is going on with it. Think I will take your advice also and see if I can find any that has sold, print and take with me.

Seconded.  :-+ Excelta rebranded them and are easier to find this way IME (Tronex makes the Lazer Line products especially for Excelta now, which are also nice IME).

I'd also recommend looking at Swanstrom, Ideal-Tek, Erem, and Lindstrom (for the right price). There's also Schmitz (http://www.schmitz-zangen.de/shop.php?lang=engl), but these are purchased directly from Schmitz or through Amazon.de (they take PayPal). They also ODM for CK Tools, Bernstein, and NWS's ESD line w/ yellow & black grips. FWIW, their pliers are the best I've ever used, especially the teeth.  :-+

It's power on but nothing on the display. The prize of do this is if I can repair it. I hope it.

I've got the TR4172 here and I really like this analyser despite its age. I've been using this one since 1990 at work and I bought it from the company many years ago.

Interestingly, I see that your display unit is different to mine. It has a different layout for the buttons. I would have expected the top display unit to be the same in terms of the front panel design.

I'm not sure how much mine weighs. The manual says 50kg but I think it may be heavier than that.

I've been on the lookout for a TR4172, I can only find one or two decent looking listings per year but they are usually a bit pricey at $600-$800 which is too much after shipping. Lots of listings are also missing the interconnects, maybe I'll get lucky later in the year.  ^-^

I've seen the elusive TR4173 *once*, I think it goes to 5GHz but I have no idea how it performs.

The TR4171 cost $200 or so, it was cheap enough that even if I didn't particularly need it at the moment, it was a good buy purely for the educational value.
Title: Re: What did you buy today? Post your latest purchase!
Post by: G0HZU on January 15, 2016, 01:16:40 pm
Wow, I didn't know that the 5GHz TR4173 even existed! I just googled for it and there are a few images. The display unit is different again with respect to the button layout.

I used my TR4172 for several years at work when designing various RF up/down converters so I am a bit nostalgic about this old analyser. When it was new it was so expensive the company had to have it donated to us as part of a big project. These analysers were extremely expensive when new. Much more than the rival HP8568B.

I bought a second TR4172 a couple of years ago as a non runner for about £250. I managed to get it running for no extra cost although I really just wanted it as a spares donor. I've seen others for sale at similar prices so they are becoming available. However, my first TR4172 has needed several (low cost) repairs since I bought it from the company. Nothing major, but it has been apart a few times now. So if mine is a typical example, I expect that there could be a few cheap non runners available at very low prices in the future.

Another HP 6114A, this one has some obvious impact damage to the front (the ground pin is a big mangled) and is QUITE dirt covered. Got it for $55 shipped to my door. Figure at that price it is well worth it, even if it takes some rehab to get it back up and running. For me, I wanted a second to match my first (version with the 10-turn knob and the large power switch) so this was a decent price.

Missed out on one that was ACTUALLY in the freaking town I am living it. Damn thing was a NOS 6114A, someone else got it back when I was on winter break visiting family.

Yep that's it. Notice the damage by the jacks, the way the body is bent in. Also notice that the dial is at 10V despite the setting being at 3.8V if it is even on. Plus there is loads of fine dirt all over it. It hasn't had a will treated life it appears.

I wasn't about to pay what he was offering. The price was WAY too high. At most I would pay around $100 shipped for a fully working one, so I offered $50 and gave a bunch of reasons why it wasn't worth what he was asking. He returned with $55 about two minutes later, free shipping was the killer part here. So I of course accepted. Based on how it appears, it will need some definite work, I just hope there isn't any major impact damage on the inside.

But don't forget one thing: "CALIBRATION NOT REQUIRED"  :scared:

That could mean it is broken, but that could also mean that it was used in a section of the company where GMP did not apply. I have had some instruments that we never calibrate because we don't really care that they are in spec all that much. We are looking for yes/no type of answers which they can still give.

Farnell trade counter score  ;D I love Leeds

EA-PS 2042-10B (10A, 42V, 160W power supply) marked £95
GW Instek SFG-2004 signal generator (4MHz DDS - unfortunately not arbitrary but still pretty good) marked £150
BNC cable for above
plus original boxes, manuals and cables for the two instruments
& 50m reel of AWG22 (pink, yuck)

£160 including VAT for the lot. Couldn't get my wallet out any faster!

Never hurts to ask what they're willing to take to clear a lot of stuff all at once. They just want it gone!

Found a few deals at a local recycler:

Hakko 470 desoldering gun (genuine). The shop had two: one marked "fully working" at $200 (CDN) and another marked "vacuum does not work at all" for $50. I haggled on the latter and paid $30 (CDN = $20 USD). Got home, cleaned it up, turned on... heater works, pulled trigger... vacuum pump is running at least. Cleared the blockages in the tip and especially in the heater, and it works like a charm. The filters look practically new, soft and not hardened with flux residue. I had always wanted a proper desoldering tool, but the price put me off. Sometimes it pays to wait.

I also bought a few rolls of solder: SAC305 just because I didn't yet have any lead-free, Alpha Cleanline 7000 63/37, and Kester 245 in 62/36/2 (2% silver) in both 0.02" and 0.01". Most spools were nearly 1 lb. $5 each, even the silver ones. And I couldn't resist a 100 foot spool (or two) of solder wick for $5 each too, since a person could pay that much for a mere 5 feet at retail. I don't think I'll ever need to buy solder or wick again.

I also found a couple of interesting Tek probes in a box full of various probes and leads. I don't really need more probes, but these were Low-Z ones, Tek P6158, which are 3 GHz, 1.5 pF, 20x (1 kOhm) probes. I know it's easy to make Low-Z probes, but it isn't easy to compensate them for flat frequency response, and it sure isn't worth it when you can buy two literally brand new Tek P6158 for $5 each!  The only little problem is that they are missing the accessories, so no ground bayonet or springs. I happen to have some extra 3.5 mm Tek bayonets exactly like the ones that would come with these, and I think I can make up my own springs when/if I need them.

 Won me a Fluke 45 on eBay, after seeing a bunch go for way too much ($300USD +). This one I got for $150, and is guaranteed working, pictures show a nice bright display, and it comes with the power cord and probes. Who knows if they are the actual Fluke probes, but one can never have too many probes laying around. Pictures when I get it, shipping delayed one day by the Federal holiday in the US today, bummer.
 Guess I really need to get started on building my bench so I have a place to put this stuff.

 It's no so much as stacking as literally having no place to use this stuff. The 8012A is still packed up from moving, almost 2 years ago. My new Siglent 1102 is sitting on the floor. When I say I need to get starting on building a bench - it's not adding bench space, it's making a bench in the first place. I have a good idea of what I want to do, even drew it up, at least the base tables, in CAD. I need to take a weekend and just build the darn thing, then I can set u0 my equipment and actually start working on some projects.

And indeed, that 565 is a classic and absolutely art-like. I want to touch all those knobs and just fiddle, it's equipment porn at its finest. Perhaps a classic analog scope should be my next acquisition - though I do need a power supply or two.

Pre ordered an Intel RealSense Camera waiting for their upcoming Android support so I'm in no hurry until that is available.

http://click.intel.com/intel-realsense-developer-kit-r200.html (http://click.intel.com/intel-realsense-developer-kit-r200.html)

What is it? Laser IR time of flight with visual as well. It can digitize 3D up to 4 meters

Specifications

- Longer range** (up to 3-4 meters indoors, longer range outdoors)
- Depth/IR: 640x480 resolution at 60fps
- RGB: 1080p at 30fps - USB 3.0 required
- Developer Kit Dimensions: 130mm x 20mm x 7mm
- Supports Microsoft Windows* 8.1 (64-bit mode), Android* support coming soon.

More info:
https://software.intel.com/en-us/articles/realsense-r200-camera (https://software.intel.com/en-us/articles/realsense-r200-camera)

So pretty much a beefier Kinect with supporting SDK.

Post by: miguelvp on January 19, 2016, 08:01:02 am
Yes, it's not for thermal imaging, it's for 3D scanning computing time of flight of the NIR laser light pulse bouncing back to the NIR dual cameras.

Edit: adding picture:

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=194962;image)

Edit: and it's stereoscopic 3D scanning btw.

Edit again: the middle image is fake, has to be. I did modify plenty of cameras to filter out visible and only seeing NIR and that black shirt should be totally white.

It's more like the ZCam that Microsoft acquired 7 years ago to do their current kinect generation:

Not so much bought as arrived ..

A couple of months ago I saw there were an unusual number of a6302 current probes on ebay. They're usually a bit rare and expensive, more often you see the amplifier modules. I scored one of the cheapest ones at about £70 but had no amplifier .. and they'd suddenly become difficult to find. No doubt because of all the probes !

Then a few days ago I saw an am503/tm501, again about £70. To my surprise, nobody else bid .. and it arrived today. So finally I can test the probe .. and the combination works!  I've been slowly accumulating current probes recently, adding various AC and DC varieties but I've been after one of these good ones for a while. Very pleased (and relieved I haven't got two items to fix!).

You write on a real paper with real ink using a special electronics-filled ball pen that otherwise looks and feels ordinary. Each pen stroke gets recorded in internal memory for later transfer using Bluetooth LE. Just got it yesterday but I hope it to prove very handy for quick ideas, sketches, EEVbLog forum posts, etc. Think DaveCad on steroids :) Now, if only I could handwrite anymore...

Sounds like a score!.  I've had poor luck recently with my attempts to begin accumulating some Tek series 500 modules. On 2 of the 5 so far have been functional.

I saw this (http://www.ebay.com/itm/Tektronix-TM502A-AM503B-A6302-AM503S-Current-Probe-Amplifier-system-/111878312756?) TM502/AM503b/A6302 current probe combo today.  A good deal IF it is functional. I'm too gun shy now to take the risk.

It does say 'For parts or not working'.

But yes, definitely a newer and better deal than mine if you can get it working without too much trouble.

I did feel happier going for a 503 rather than an 503A or 503B - although they're not as nice, comments elsewhere on this board suggested they might be easier to repair (if necessary).

This model has 0.25V mode, which is lower than Vf of a silicon PN junction or even a schottky junction.

Trust me, this thing worths every penny if you work with lots of SMD parts.

PS. There are some minor firmware bugs that should not be there considering it is a $400 device, but no big deals at all.
Admittedly, this is only the slightly lower end "LCR Reader", not the ST5. Then again, the diode tester is not that useful anyway and this costs only half of the ST5 for only slightly lesser specs.

I got my Rigol DS1054Z today, and already used the online keygen, for the additional bandwidth, seems like a really nice little scope, with 4 channels. And so much faster to set up than the PC based scope I'm used to at work(automotive).
I also got a free Uni-T DMM with the Rigol, a small handy model, perfect for car fuse checking and such things.
And ordered some bnc to banana adapters, so I can use the original break out cables with my scope, and a hand full of BNC end plugs, to protect the unused ports from dirt.

Where did you get that bundle and for how much? Hope it is an online store  ;D

It's from here https://www.rigol-uk.co.uk/ (https://www.rigol-uk.co.uk/)
The adapters and such are from aliexpress.

That free DMM doesn't appear on the store  ??? Did they sent to you the gift without mentioning it on the store?

It sure does, remember to use their desktop version og the site. And look at the left buttom corner. Free DMM, it says its only for UK ordets, i got one anyways, and a UK power plug, and the EU one.

Oh I missed that  |O I'll check this out to see what's better: buy there or on the Batronix store.

I finally had enough of the cheap eBay LED magnifier lamp I'm using for my teardown and repair bench. So today I took advantage to Zoro's 20% off sale today to buy a Luxo 5 diopter LED magnifier (https://www.zoro.com/luxo-magnifier-light-675x45in-led-gry-225x-18945lg/i/G8487035/#) and a 4 diopter Luxo Stays add on lens. Also picked up a 1.2 mm chisel tip for my Hakko fx-951 as well.

FWIW, you'd do better to go for Probemaster 815x spring loaded probes (http://probemaster.com/dmm-multimeter-test-leads/spring-loaded-test-leads/) instead (they ship internationally), as they're better made and will last longer.

I say this, as the Fluke/Pomona spring loaded (pogo) probes have a bad habit of the wire breaking inside the insulation where they exit the probe body (no strain relief). Fair number of complaints about their build quality/reliability if you search the forum.

Here's a mini teardown of the Takeda Riken TR6110B DC Voltage Standard, they're known as Advantest now.

I don't know if they made any other dedicated DC standards, this might have been their only one apart from their general purpose DC sources/SMU's.

So it's only fitting then for the unit to be calibrated by its much younger sister (Advantest's best multimeter, the R6581), ahh it brings a tear to the eye....

Wow very interesting, it looks like a functional copy! Thanks for the tip. ^^

The 1mV control pot is damaged on mine, it doesn't seem to work at all except give a 1mV jump all at once, I think I should bypass it incase it is affecting stability. On first impressions it looks like it has a tempco of about 2ppm, on cold it reads 50 ppm low and it warms up in a couple of hours. It's short term stability is about 0.1ppm, though thermal emfs are a real pain for a 1V reference.

The temperature on the outer shell of the oven was about 40C.

I think just a simple LM399 surpasses it, let alone a LTZ1000. I have no use for a 1V reference and I much prefer a 10V one, I wonder if I can fit a 10V reference inside and substitute the 1.019V setting for it... :P

It was on Yahoo Auctions (basically Japanese eBay), and I paid JPY3100 or about USD26 or so.

Even if it didn't work at all, I *really* wanted to see inside it and I figure I could at least salvage the case or resistors for other projects. Those binding posts are still silky smooth to operate, I like it very much.

Literally the only info I have on it is that it is "2 ppm". I don't know what timeframe that is, probably 90 days?  :P

Thanks!  ^-^

They really do make great gear, especially for hobbyists because you can get some fantastic deals as they don't carry the name of Tektronix or HP/Agilent.

The R6581 cost a measly JPY50k or about USD420, no joke.

So basically the R6581 was Advantest's answer to the HP3458A, it also has 2 source artifact calibration and auto calibration. More importantly, the R6581 actually stores the auto cal constants in battery backed up memory, and I bet you can guess why it was sold for so cheap after 17 years of use. The meter was autoranging like a madman and it refused to show a reading because it lost its auto cal constants.

$10 later for a replacement battery and I'm still smiling...  ;) Maybe it is the deal of the century for volt-nuts.

It seems like you know to get Advantest equipment for a really low cost.
I have never seen the R6581 for under $ 3000

So, you probably got the R6161 really cheap as well.

Just want the case, transformer, meter, switches and binding posts.

Sorry for the late reply, I keep getting a "502 bad gateway" error when I try to get onto the current page of this thread.  There seem to be a few tricks to getting around it, though.... such as clicking directly on the page number from the "replies to your posts" page.


Is there really no teardown of a 2901 on the forum already?!   huh...
Well then, yeah, I sure will!!    All that I've done thus far is cleaned the case & face up a bit and poke around inside + test it out. Bad switch, few out of tolerance resistors in the 3.6V power supply rail, faulty 2ns circuit.... (the diode is good, THANK GOD!)  so I suppose a teardown/repair is in order!

That's some great info to have!  Thank you for offering, I will certainly take you up on that if the need arises.   From what I can tell thus far though, it appears the only real issue this 2901 has is the 3.6V rail being .5V low.  I already checked and the 10K's, 15K, and the precision resistors are all a good bit out of tolerance.  After that and possibly a few others off the rails into the timing circuits and it should be good to go again.

Wow!  That could have gotten ugly!  Good thing they listened and put the styrofoam there.  Did THEY put the holes in for the knobs, or did the knobs chew through during shipment?  Either way, from the photos it appears that it made it with controls undamaged, so that's good.

There wasn't much wiggle room towards the back or front of the scope in the packaging, so my guess is they pre-pressed the foam over the knobs.  I can't help but wonder if they would have bothered to do so had I not asked.

I just got one of my Kickstarter "rewards", an Nscope.  It is a small PC board that plugs into the end of a standard plug-in "breadboard"  It connects to your computer via USB and provides + and -5V to the breadboard power rails. It is a signal generator for a couple of channels, and a 4-channel oscilloscope. With open-source API so you can code your own interface, etc.  Pretty cool, IMHO.  I can't wait to play with it when I get home from work tomorrow.

An fleabay purchase marked as a HP5253B and doesn't power on. I got the 5245L as well and with one fuse later it lives!
Some work on those BNC, using robrenz's techniques, a bit of panel cleaning, one loose capacitor (the bakelite base cracked- don't make them like they used to) and hopefully it will look pretty good.

Just under $2k, came with a full set of auto compensating 500mhz passive probes, which look brand new. The scope was also as clean as in that picture, whoever owned it before me must have not used it very much.

I've been very pleased with it so far. The UI is a big improvement on my Rigol DS2072A. FFT is also pretty usable, there are a few unique features I haven't seen on other scopes as well, like 3 different interpolation modes, Z input for the XY mode.... and it boots in like 2-3 seconds, fastest booting scope I've used.

Dell M410HD replacement lamp assembly - $1 shipped

I don't have any application for the modem; I just want to see what its insides look like. The projector lamp was a total impulse buy but I'm thinking up some plans for a ridiculously bright (and hot) bench lamp.

New XR2206CP function generator IC. I blew my home made function generator up last night so am building a new one from scratch with all the kinks worked out of the original design and integrated sweep generator.

Perhaps interestingly the IC is the same price now as I paid for it in 1994. So it has actually got cheaper after all that time!

But there are much more dramatic examples than that. You can buy a whole PC with MS Windows on it for less than what a keyboard used to cost back at the beginning of the PC era (1984).

I have used one of those and they work quite well as long as there are no components along the edge as there is a slit in the black holders that the pcb sits in.
If there are components the tension from the springs will hold it to a certain degree as the springs are quite strong.

Yes, I have used mine (for which I apparently overpaid, thanks a lot, @gameru!)
The "overhang" is quite small ~2mm and I have not found it to be a problem yet.
As @azer said, the spring is properly strong enough to hold the board at whatever angle you wish.

The base pieces are steel, but the upright parts are plastic. But it seems beefy enough to survive years of hobby use.

When I bought it, the price was US$12.95 so I don't feel quite so bad.

The backplate is steel, and it has rubber feet. So it's stable and it provides somewhat of a heat shield for when I work with the rework hot air station. It will not work for you if you work on bigger boards but I had good luck with 10x6cm boards I've been assembling.

I just measured it, the clamp will extend to 7.5cm, there is really no limit to the other dimension as there is no obstruction that way. The only other issue I can see also is if you're working with boards that might have big components on both sides, since there is a rail in the back that could be an obstruction.

Most benches existed in real workshops,& could be constructed in any depth required.
In many cases Oscilloscopes had their own trolley & did not occupy bench space at all.

Bench depth was more due to the type of equipment commonly worked on.
Much of this was quite long,because it was designed to fit into 19" racks,which limited the width,so cases were longer to allow adequate internal space.

Home hobbyists were lucky to have an analog multimeter,so room on their benches was not a problem.

My bench is plenty big enough, but I don't like anything sitting on it. My shelves are 12" deep with about 1" gap at the rear. This counter is nearly as long as my Tek 2247A even though the front panel is less than 1/4 as large! With the handle removed it fits on the shelf barely, up against the wall in back and a slight overhang in front. Maybe they make brackets that are deeper so I could space one shelf a bit farther from the wall.

I guess I just lucked out!!  It started at $0.99 and there was only one other bidder who put $5.00 on it.  I put a $40.00 max bid on it before I left for work and fully expected to lose it.... but once I got home and checked on it....... POOF! Mine for $5.50!    ;D

It's apparent that the timebase plugin is in the wrong slot which may (or may not) be the reason for the wacked out display. I have all of the replacement knobs already lying around, too.  First things first though - it's going to get a thorough cleaning, visual check, capacitor check, and component reseating before I even attempt to power it on.

Here she be.....

I have a 561a tek scope with 2 plugins 1-2a63 dif.amp and 1-53/54d dif. amp.
that could be someones for free.
pick up only in east la county or north san diego county usa.
It has been sitting on a shelf for the last 30 years dusty but 30 years ago it had a trace.
I had thought about pulling the tubes and parting it out but if some one wants it come and get it.
PM me for details.

The pull tabs are gone  :scared:
Be careful taking those out. I did use needle pliers to unlock them but it is tricky to do.

Not too tricky but don't force them out.

I got one for $50 but that included also a 5110, they were in pretty bad shape both of them but a bargain nethertheless

Did you have to do anything other than clean them up?   I am already looking for some plugins - both working and also some extra cheap units for the mechanical parts.   If you have a thread for their repairs (if you did any) please link it in for me. 
Thanks for the heads up about the pull tabs... I will start looking into what the best way to remove and temporarily repair them are in case I don't have replacement pull tabs in time.

The mainframe was fine, I did get new plug ins and followed the calibration. So other than the cleaning, I didn't have to do a thing on the mainframe.

Only repair I did was on an amplifier plug-in for my 7603, due to physical damage.

cordless drill/screwdriver:

not something for building a house, but I hope it will be OK for small jobs in a city apartment.
didn't do much market research - the shop didn't have any Makita in stock so I went with this Bosch...

I bought this too, but with a hard case instead of a bag. I love it! Since then I added the hand held vac skin.

Well, it appears that I have just purchased a Tektronix 7854 mainframe for little over $100.  That in addition to the DS1054Z and new Hakko soldering station.

I suppose I will be selling my 7613 mainframe and one of my 485s. Or maybe a Tek 106 instead..

Escort EGC-2230 for about €100 delivered.

(http://www.stochasticgeometry.ie/wp-content/uploads/2016/02/2016-02-15-21.42.36a.jpg)

Didn't look too horrible, powered up okay, but the waveforms were all over the place - the 2MHz square wave looked like an ECG. So out with the screwdriver...

(http://www.stochasticgeometry.ie/wp-content/uploads/2016/02/2016-02-15-21.44.29a.jpg)

Lots of discretes, lots of solder joints to check, but hang on...

(http://www.stochasticgeometry.ie/wp-content/uploads/2016/02/2016-02-15-21.46.01a.jpg)

Well that don't look right! I guess the courier wasn't exactly gentle and shredded paper doesn't do as good a job as bubble-wrap. A quick soldering job later...

(http://www.stochasticgeometry.ie/wp-content/uploads/2016/02/2016-02-15-22.28.00a.jpg)

Square wave is still a bit janky, but I've not exactly used a terminated BNC connection and it's the upper part of the spec'd range on a 20-year-old generator...

(http://www.stochasticgeometry.ie/wp-content/uploads/2016/02/2016-02-15-22.27.53a.jpg)

Triangular isn't much better.

(http://www.stochasticgeometry.ie/wp-content/uploads/2016/02/2016-02-15-22.28.07a.jpg)

Though sine seems reasonable.

(http://www.stochasticgeometry.ie/wp-content/uploads/2016/02/2016-02-15-22.28.11a.jpg)

And to be fair, at lower amplitudes and slightly lower frequencies, everything's fine (and it does what I need for the current project quite handily).

The DC offset's kaput though - I turn it on at all and everything gets clipped horribly no matter the function selected.

I think I'll have to go over the board a bit more carefully and check for properly seated ICs, clean the switch contacts and that sort of thing.
Anyone happen to have a manual for the EGC-2230? I could only find the EGC-3230 online.

By coincidence, I got that sig gen's sibling, the EGC 3230, a couple of weeks ago (also known as the KENWOOD FG-273 according to google).  I thought mine was on the blink too but didn't really care - I was half looking forward to a fixer-upper given that the service manual is available for download and it only cost 31 UK beer-tokens inc postage.  Turned out I just needed to move the DUTY knob all the way down...  Not sure why that would affect the sinewave output, but it did.  Can't find a user manual - only the service manual for free - tho even I should be able to work it out...

These two bad boys! They came in original packaging, which was falling apart and was almost 30 years old. 10 bucks each on ebay, but they are smooth as hell. Stuck a knob on one, and turning it is a pleasure. 2x320 pF and they have a 100K pot at the ends (which measures 99.49K!). Great for building transmitters and receivers (SW).

I've been lusting for one for a long time. The best I have seen so far on eBay was about 210Eur shipped (to Austria)! Does anyone know of a good (i.e. cheaper) place to buy used testing equipment in the German speaking world (other than eBay of course)?

For quality tested equipment in Germany I'd recommend Helmut Singer. His prices aren't at the lower end of the scale, but you know what you are getting and he has a huge variety. If you happen to be in Aachen you can call by and check out the stock for yourself: http://www.helmut-singer.de/ (http://www.helmut-singer.de/)

I made a similar toy for my son when he was 2 (now almost 5). It has 3x 7-Seg displays and two buttons to go up or down a number on the display (simple PIC with a few passives), built into a clear plastic case that some Apple product came in. He still plays with it now, almost 3 years later and he even learnt to count from it.

Waiting for the package to arrive...

They will be a nice replacement for utterly shitty probes that came with DS1054Z and are completly destroyed after 6 months of use.

Yes, general consensus seems to be that the RP2200 probes are crap for any decent HF work..  I'm not 100% on what probes I will use with mine yet, but several people have said that after the DS1054Z is "upgraded", it's usable bandwidth is over 100Mhz.   I intend to pick up some 200Mhz or higher rated probes - I'd like to try and get ones that are also going to be compatible with my 7854, though, so more like 500Mhz+.

Anyone have a graph showing newer Tek probes for comparison? 
I have the following for older probes:

 And I finally have the last missing piece to finish my equipment needs - just won an Agilent E3610A power supply. Was listed at $85 plus shipping, I offered $75 and they took it. Comes from a test and calibration supplier (though they aren't calibrating it at this price - they do offer to calibrate it but did not supply a price for the service), and is guaranteed to be tested and working. Also they mention their packing methods - so I don't think there is much risk in having damage from shipping. Another plus, it comes from NJ (and I am in the eastern half of PA). This unit will suffice for now for my generally low current low voltage projects, though I'm sure in the future I'll want something a bit more high power, and maybe programmable (just because).

Comes from a test and calibration supplier (though they aren't calibrating it at this price - they do offer to calibrate it but did not supply a price for the service), and is guaranteed to be tested and working. Also they mention their packing methods - so I don't think there is much risk in having damage from shipping. Another plus, it comes from NJ (and I am in the eastern half of PA). This unit will suffice for now for my generally low current low voltage projects, though I'm sure in the future I'll want something a bit more high power, and maybe programmable (just because).

Great supply at a great price, you won't be sorry you bought it.

I just bought one of these for $70.00 shipped from amazon.
It is not some thing that I would use very often but looks like a handy tool to have on the bench.

Very nice kit. Just take note of how long does it take to be broken, because such a complete kit for that price shouldn't last long  :'(

It should be ok for me as I will not be using it much.
I don't except a great unit for that price, Although the reviews were good.

It seems an excellent unit. It must be perfect for someone like me who doesn't use the soldering iron a lot, but likes to make good soldering jobs. However you should always have a spare crappy one just in case that one fails right when you need it (damn Murphy!!!)

Asus RT-AC5300 - spider looking thing

Way too much for my network here at the house/shop/garage, except that the shop/garage are 200ft+ from the house.
Still running off a classic blue Linksys G router, using another Linksys G router (both DDWRT flashed) as an extender/repeater, and another blue Linksys B router (bone stock firmware) as a hub.
Only got 25Mx2M DSL here, but now I can put the backup server in one place rather than hauling the external drives around to all the PC's one a week.

It's not really a purchase, since I got it for free, but today I got in the mail from Microchip the MPLAB Express Evaluation Board.   They had some deal when they launched the online MPLAB Express development system where the first X number of people would get a free board.  I hit the link and signed up and looked around a bit, but the response page I got led me to believe I was too late and wasn't getting one of the free boards.  But it showed up today.  Will have to try it out when I have time.

Last time I programmed a PIC it was, I think, a 16C54 in a ceramic package that had to be erased with a UV eeprom eraser.   :)

I think this one will be a bit more convenient.

OK.  That makes sense! :)  Assuming their crystal is better than mine.  I wonder what they use for a reference in a fairly inexpensive frequency counter.

 Bunch of model train kits. Have to balance the electronic purchases.... Damn West Coast US people, set all the auctions to end past midnight Eastern time, I'm old and need to be in bed before then. So I just stuffed in my top price and hoped for the best. 3 out of 6 when I checked this morning. I guess I did OK. The ones I didn't win aren't particular rare items or anything I can't find any time. One of the winners I was very surprised at, since I checked (like always) if it's still in production and what I can get it for at my favorite shops - eBay is NOT always a bargain! Sure enough, it's available for purchase new, almost $64USD. There were no other bidders, so I got it for the opening $19.99 plus $8 shipping. A steal. And they say model railroading is an expensive hobby....

You would think that would be a bad move; setting the auction to end at say 6:00 PM PST would be wise. :)

One recommendation I have to someone looking for a counter is that for a bit more you can get a SDG2042X which has a very decent counter built in.  They even added min/max/avg features to it per my request.

I'm converting an abandoned pnp machine prototype to a CNC machine. For this project, I received this week:
- A set of steel blocks, machined to 0.xx um accuracy (for calibration): http://www.aliexpress.com/item/1-100mm-Block-gauge-set-38pcs-set-1-Grade/521114897.html (http://www.aliexpress.com/item/1-100mm-Block-gauge-set-38pcs-set-1-Grade/521114897.html)
- Cyclone dust collector http://www.aliexpress.com/item/Cyclone-Dust-Collector-Bagless-Never-Plug-Low-Energy-Consumption-High-Efficiency-Cyclone-Dust-Collector/32298080759.html (http://www.aliexpress.com/item/Cyclone-Dust-Collector-Bagless-Never-Plug-Low-Energy-Consumption-High-Efficiency-Cyclone-Dust-Collector/32298080759.html) and a barrel for it (from a local store).
- Laser RPM meter http://www.aliexpress.com/item/Freeshipping-Digital-Laser-Photo-Tachometer-Non-Contact-RPM-9852/640461991.html (http://www.aliexpress.com/item/Freeshipping-Digital-Laser-Photo-Tachometer-Non-Contact-RPM-9852/640461991.html)

Sometimes I'm amazed about the efficiency of the human race. The last item is a meter with a laser and an IC (or two, haven't looked inside): In other words, some parts are manufactured with nanometer tolerances; it is made of plastics (starting from black dirty stuff hundreds if not thousands feet below ground) and some metal (starting from the wall of a mountain). Still it got to me from China for less than 9€ and everyone involved in the process, mailman included, think the effort was worth the money!  :-+ for humans, also :-o.

Intel NUC6i5SYH, that will become my new main computer.
My old i7 920 based desktop is a bit too power hungry (150W idle) to run 24/7, and will become my gaming box from now on (which means it will only be running for an hour or two per month..).
The NUC has a much more reasonable power consumption at 19W idle.

I can also report that it works nicely with three high resolution monitors using both the HDMI port and an Displayport MST Hub.
Connected as follows:
NUC HDMI -> HDMI on left 2560x1440 monitor (in portrait mode)
NUC Displayport -> Displayport MST Hub -> Active Displayport to dual-link DVI adapter -> DVI on center 2560x1600 monitor
                                      |-> Active Displayport to dual-link DVI adapter -> DVI on right 2560x1440 monitor (in portrait mode)

Some USB 3.0 toys, for my 'camera on microscope' project.
Yesterday:
 - Touptek L3CMOS05100KPA 5MP c-mount USB 3 camera. http://www.touptek.com/product/showproduct.php?lang=en&id=70 (http://www.touptek.com/product/showproduct.php?lang=en&id=70)
   (also 3 different magnification microscope tube to c-mount adapters. Only one needed for this camera, the others for use with other things.  Plus a calibration slide - it has a tiny little ruler.)
TNT got that package from the factory in China on Monday, to my door on Wednesday. A day earlier than their own estimate. I'm impressed.

Today:
 -  A 5m USB 3.0 cable. (the one that came with the camera is only 1.8m.)
 - Three USB 3.0 PCIe cards. None of my PCs had USB3.0 ports, they will now.

Getting those things today was a lot more hassle than the items from China. First I drove from East Hills to the Auburn MSY store, expecting to buy them there. Common item, in their catalog...
Nope, they were out of stock. None till next week, not even sure about that. And no they can't check stock at their other stores. I got the address of the MSY shop in Ultimo, since I've never been there and had no idea where it is.
My car has no aircon, and it was already hot. Drove to the city on Parra Rd. Finding a parking spot wasn't too hard, but then finding the store...

Back in Auburn, the shop guy had read the address out to me off one of their own pricelists. The ones with tiny, tiny print.
He'd said "sixty eight slash fifty five A Jones St", which I wrote as 68/55A.  Wasn't sure what that actually meant, but thought it would be clear enough when I got there. In Ultimo, I walked the entire length of Jones St and there's no such address. Nor any sign of the store. Eventually asked in UTS, fellow showed me a google maps marker in a building at corner of Jones and Mary Ann St. Complete with street view of the shop front. Try again.
At that corner there's nothing like the streetview image. Seemed the only possible building was another of the the UTS buildings. Went in, no shop. Asked some people in a computer lab. Got directed to the park across the road.
Ah ha! The MSY shop front is in a kind of lane walkway facing the park. And the correct street number is 558, shop 68.
The shop front also bears no resemblance to the google street view image.

After all this drama I was expecting them to be out of stock too. But no, they had 3 left. I bought them all.
Then the M5 was choked, so I took the long way home. Those USB 3 boards took pretty much the whole day, and I'm buggered.

I just received A BK 3010 function gen.
Only problem it only outputs square wave (that part works fine) change on switching the mode switch.
sine and triangle  wave  makes no change. on both of my o scopes)
I have contacted the ebay seller no response yet.
Does any one have any ideas why?
BTW I am a o scope dummy.
I want to use this to make a hf gen to get the next door neighbors dog to quit barking.
Yes I am an evil person.

I plan to use a 16 khz. triangle wave turn on whenever the damm dog starts barking with a 60watt amp and a tweeter.
This dog is driving my wife and I crazy it starts at 7:30 am and does not stop.
I considered shooting it but that does not seem to be a good option.

The neighbor is trying to help but it is not working.
Short of shooting it does any one have any ideas

thanks for the link.
I did not see anything that I have not seen before.
60 watts @16khz. should do the job.
I tried the dog whistle app. It did not work to well until it was amplified.
The problem is my phone is needed for other uses like phone calls.
the amp with a sound activated switch will work well as soon as I am able to produce the 16khz triangle wave.

 My HP E3610A arrived today. Definitely a company that knows how to handle instruments - in addition to foam in place packing, they had 2 layers of cardboard wrapped around the unit itself, which was also wrapped in plastic and had a large piece of foam taped on the front (of the plastic packaging, not on the body of the unit itself) to protect the knobs and binding posts. Definitely used, but very clean - just a few paint chips on the heat sink. Also this has to be an older unit, since it is HP branded, not Agilent. Too bad most of the other stuff they list on ebay is microwave and high frequency RF splitters, attenuators, and the like. Now I gotta get my bench built. Hopefully this weekend - so my next purchase should be lumber and other building material.

The neighbor is trying to help but it is not working.
Short of shooting it does any one have any ideas

You're lucky it isn't during early hours of the morning, which some of the dogs around here do. One guy keeps a kennel of greyhounds, and those routinely have a collective fit around 4am for some reason. Not so much lately, thank god.

There was a thread on here a while ago along the lines of "Who does not love dogs?"
Full of people who have apparently never been forced to live with unbearable dog barking noise nuisance, or having their own pets torn to pieces by escaped vicious neighbor dogs (happened to me twice.)

Anyway... have you looked into your local government's noise nuisance regulations? I'd suggest starting to make full-day audio recordings of what you are suffering. Buy a little pocket MP3 player that also has a record ability (ideally to WAV, on a uSD card.) At the start and end of each recording speak the date and time into it, for the record. Put the recorder out in your yard, under rain and wind cover, and leave it alone so it's a fair representation of the situation. ie it wasn't you provoking the dog to bark. For the wind cover, I use a short (~150mm) length of 100mm dia PVC pipe, one end open and the other end covered with a bit of thin cloth. Lay it horizontally and just put the recorder in the middle. This stops most of the 'wind flutter' sound you get if you leave the recorder exposed. Most recorders these days can run for a day on a new AAA battery. Start the recordings before the dog gets going, so you have a record of the ambient noise level 'before' and to show the dog is just barking for no reason.

Accumulate a series of these recordings on your PC, to show it's a continual problem not a one off.
When you have a week or two, make a formal complaint to the council (or police, if you can trust them not to kill everyone in sight.) If you want to produce a visually clear document, get a sound file editing utility that can show waveform profiles. Dog barking shows up very prominently as a series of spikes. So you can include immediately comprehensible pics of how the barking goes on all the time during the day, how it clusters in bursts, etc.

If a complaint isn't likely to achieve anything, then maybe start playing back the barking records very loudly between midnight and dawn, for your neighbor's education.

Other than that, I could only suggest responses that are probably not legal. Shooting it isn't one of them. Not subtle enough. But ultimately, my experience with nuisance dogs is that the only real solution is for it to not be there anymore.
Peace and quiet in your own home is a fundamental right. Some exceptions now and then, like loud parties and dog barking for a good reason, fine. But continual stressful noise that is ruining your life - it's a form of assault.

Definitely a company that knows how to handle instruments

Sounds like they do know how to pack. Which seller was it? Always good to buy from those with some shipping skills.

 Seller was Alltest in New Jersey. Among other things they offer calibration services, maybe I should see how much they would charge to calibrate my Fluke 45, 8060, and 8012.  Thought he 8060 and 45 are well within specs compared to the calibrated standard I bought that does AC and DC V and I and has a series of precision resistors. I have them saved as favorite seller in case the have some other nice gear that I need - I still wouldn't mind a nice analog scope, and at some point I will need more than a single power supply and/or one that goes over 15 volts. But, next step is actually get this all set up on a bench so I can start having fun.

 Edit: their ebay name is express_test. Also they have another E3610A for the same $85 that mine was, on which they accepted my offer of $75.

I'm looking forward to it as well.  I've posted a few more random photos of it taken mainly out of boredom; they're in the gallery linked in my previous post.  I was able to download a PDF scan of the manual from Keysight; the quality isn't the greatest but it'll at least get me started.  Hopefully I'll be able to get an original somewhere on evilBay.

Like everything of that vintage that's HP related, the mechanical construction is first rate.  :-+

I'm debating trying to power it up, but would first need to scrounge a fuse and fuse holder insert as the original was pilfered at some point while it waited in purgatory at the surplus place. Perhaps tomorrow, after I've looked at the manual a bit more.

I've got a big pile of vintage fuse holder assemblies.   If you can specify some details about it, I may have what you need. I don't have any vintage HP gear so I'm not sure which ones they used. 
 It'll cost you an arm and a leg, though...   ;)   haha just kidding. Just reimburse me for shipping and it's yours. PM me if you're interested.

A2AT -

I very much appreciate the offer, though I doubt I'll need to take you up on it - it's just a bog standard panel mount fuse holder (visible halfway up the front panel just inboard of the right side handle) that someone liberated the bayonet cap from.  If the fuse cap from a replacement holder won't fit, then with two quick solder connections and one nut, the whole thing can be replaced.  It even appears to be relatively accessible!  I the mean time I'll try to borrow something from another instrument to test it.

BTW - I also snagged Tek 503 and 504 mainframes in the same trip, along with some big honkin' filter caps to replace those in an old rack mount 506 I have, too.  And so a new gear addiction is born....

Well, some good news, and some slightly not good news.  Some of the good news - the two missing boards (A9 and A23) are not needed for the meter to function.   :-+  The slightly not good news - they ARE needed to use it with the 2410B AC/Ohms Converter that I inadvertently bought on my last trip (thinking it went with the 2402A I picked up then), which was a large part of the impetus to hunt down and buy this.   |O  Hopefully I can either scrounge them somewhere, or, more likely, fabricate replacements.

Additional good news - I found and bought a copy of the operating and service manual on evilBay. And with a fuse holder cap borrowed from another piece of gear, it fired up without any immediately evident issues and the magic smoke remained inside.
(https://pmanning.smugmug.com/Electronics/HPDymec-2401C-Integrating/i-rj5jPkx/0/L/image-L.jpg)

A few minutes with a paper towel and some windex made the front panel considerably more presentable, too.  (Since the meter is basically a voltage controlled counter, it wasn't difficult to incorporate some frequency measurement capabilities into it, so they did so.  This is showing the counter's self test function - and its age - note the frequency readout is in kc, not kHz.  IIRC, the counter is good to about 300kHz or so - no great shakes, but I can't see complaining about functionality that was basically included for free...)
(https://pmanning.smugmug.com/Electronics/HPDymec-2401C-Integrating/i-RXxd7qZ/0/L/image-L.jpg)

I'll start a thread in test equipment or repair once I get it on the bench and begin to give it a proper going over.  The sample rate knob will be replaced with a proper HP knob at that time.

Hi Pat that looks lovely, I do love Nixie gear, it looks very similar in vintage to an HP 5245L I am in the process of trying to repair, I am not sure if you have seen the work of robrenz here on some old HP gear, he has done a lovely job. He also gives some good advice about cleaning knobs etc.

Good luck re the restoration.
Robert
Title: Re: What did you buy today? Post your latest purchase!
Post by: Cubdriver on March 09, 2016, 03:05:02 am
Yes, Robert - I've seen robrenz's work (incredible - when he's finished with them, the instruments look better than they did when they came off the assembly line!!) along with that sticky.  Both are helpful and inspirational, and I've spent a good bit of time looking through the posts.  IIRC robrenz is the one that prompted me to try the magic eraser sponges on things after seeing his results; they do truly work magic.  (They also need to be kept on a high shelf - my cats consider them prey and when I forget to hide them enjoy chewing them into little pieces of sponge that wind up scattered around on the floor. |O)  I can aspire to robrenz's level of refinishing, but likely won't get within spitting distance of it.

I like the old nixie stuff, too (obviously) - got started with it after a post a few years ago on the HP mailing list mentioning people cannibalizing 5245Ls for their display tubes as they were relatively inexpensive.  I looked on the bay and almost immediately stumbled on one for very little $$ and bought it (not planning to cannibalize it, rather more to save one from that possible fate at someone else's hands).  I decided it was a very cool old piece of equipment, and then began hunting others of similar vintage - attempting to kind of 'collect the whole set' for no logical reason other than they're interesting pieces of hardware.  This naturally led to the nixie meters as well, and here we are.

If only the damned things didn't weigh so damned much - they cost a fortune to ship, and are a bear to pack.  If/when I get the 2401C and 2410B fixed and talking to one another, I'll have a six digit bench meter than can measure AC & DC voltage, and resistance.  It will be 19" wide by 19" deep, roughly 15" tall, and weigh about 100 lbs total.   :-DD :-DD

I ain't right in the head, I tell ya!!

I wish you luck with your 5245L - it's a fine boat anchor!  What's going on with yours?

-Pat

Edit to correct typo - I bought a 5245L, not a 5243L.  D'oh!

Hi Pat, re 5245L the heater in the OCXO shorted, took out power PNP , signal PNP (both Ge), 4 diodes, one transformer AND COUNTING!!!!!! The build quality on this vintage gear is just such a delight; recently a Agilent 53230 counter of mine went intermittent on Ch1 (of course out of warranty) , the BNC is directly mounted on the only PCB card with bugger all other mechanical support so the PCB fractures, fortunately there is some pads nearby so an easy fix but Dave and Bill would be turning in their grave.
Title: Re: What did you buy today? Post your latest purchase!
Post by: Cubdriver on March 09, 2016, 09:18:53 am
Ouch!  Sounds like the shorted heater REALLY did the scorched earth thing and made certain that a lot of the magic smoke got out.  Hopefully you manage to get it sorted and nothing more has been taken out by the short.

I agree wholeheartedly - the build quality is wonderful.  This was definitely Cadillac/Mercedes/Rolls Royce/<insert favorite luxury brand here> gear in its day, and it shows in the construction.  It's well laid out, the manuals tell you how it works and how to troubleshoot it (a far cry from today when it seems you're lucky if you get a block diagram) and have component layout diagrams and schematics.  Heck, look at how much of it is still operational 30, 40 and 50+ years after it was manufactured.

It sounds like the random fault generator in your 53230 worked exactly as designed - do not break until the warranty period has expired. I'm glad to hear it was an easy mechanical fix, but as you imply, it shouldn't have happened, and wouldn't had a bit more care been used in the physical design to isolate the connector from the board.  Unfortunately it seems that the bean counters have taken over almost everywhere, and look to squeeze every bit of cost out of things, long term reliability be damned.  Yep, Dave & Bill are very likely acting like flywheels.  Ugh.

Here's wishing you success with the 5245L repair.

I went on a bit of a hunt around the local council recycle centers and picked up a few items of interest, I was specifically after another metal housing for a power supply project and came across a few of these units listed below, I grabbed one and at only ten bucks each couldn’t go wrong really considering that I also ended up with a few 10 x 38 10 Amp HRC fuses that went with the unit  ;) so now have some more spares for the multimeters.

The power supply itself measures H145mm x W230mm x D300mm overall and the toroidal transformer which I don’t really need is H80mm x D200mm and rated at 2000 watts, 8.33 Amp and is split into 120 + 120 Volt on the secondary, the label on the case says Peach Audio Balanced Power Supply and after a bit of research indications are that these are worth big bucks new but they might be just another one of those audio foolery type gadgets but that’s not for me to judge, the toroidial transformer is from Tortech Australia model 2000-2-120E and is dated 2001 but not listed on their site so it could be a custom job, anyway it all works as is and weighs a ton, I have put some links below for those interested.

 A followup on the E3610A. I got an email from the vendor saying they may have shipped some dodgy power cords. Indeed, the picture was of the one they included in my power supply. I'm not sure what the issue is - I did look over the cord and I don't see any obvious defects, although as a Wung Hung Lo brand I don't think I'd trust it up to the 10 amp rating printed on the cords. But the 3610 is fused at 2 amps, thus is must draw no more than 2 amps, so it's probably OK. I've already used the cord to power it up and check it out, didn't notice anything like maybe the plug blades being loose that they'd pull out or anything. However, in interests of safety, the vendor is mailing out free replacements to everyone affected. So another  :-+ for Alltest, for sending out both a notification email to all customers who might be affected and then supplying a free replacement. Perhaps I'll slice into the supposed defective one and see what the issue might be - perhaps it's aluminum or steel wire instead of copper inside.

If you buy in those quantities, you probably were a big spender.  Most vendors have a very serious low-quantity markup and if you do mail-order from a cheap vendor the postage will be several times more than that parts.  I have those parts, pretty sure I bought 20x or more of each when I got them and then I never have to buy them again.  In fact, just used a LM358 on a little absolute-value test circuit I just completed.  Turned out to be super accurate, considering it is using a 10 cent op-amp.

You're right. I think that cost £3 for perhaps £1 of parts. I could go for quantity but it's  accumulation then and then there is mental, storage and time cost added to it. For a one shot project, I don't mind paying through the nose.

Bought myself a Lenovo T410 Win 7 Pro 64-bit Core i5 M520 with 4GB RAM and 280GB HD. It is to replace my even older laptop (ASUS M51A 2gb RAM Win7 Pro 32-bit 250GB HD). Good for business, sucks for graphics/games (which is good because otherwise I would be easily be addicted to playing games), but only cost me $240 Canadian/AUS all-in (shipping/tax/etc.) or about $180 US.

Not a bad investment considering it does everything I need, seems fairly robust and appears to be better quality at this price range than the cheap garbage I can pick up at Walmart or Bestbuy for the same price range or even more. It has tons of ports on it, and came with a DisplayPort-2-HDMI dongle so I could hook it up to my TV.

Now to install some EE software on it...  :)

If the product depends on it then I wouldn't want to touch it with a two-metre stick. Especially considering that in most countries there's no requirement about where is live and where is neutral on the wall socket. I didn't even know they actually consider this when making these IEC cables.

@Circuitous, I have a 53230, channel A went intermittent (out of warranty of course) , the BNC s are mounted straight on to the PCB without much mechanical support, I found a crack in the PCB trace. an easy fix, if it happens to yours (hopefully not) - mine hadn't had a lot of use either! see reply 28 photo on https://www.eevblog.com/forum/testgear/comparing-two-hp-z3805a-gpsdo-10-mhz-frequencies-for-lab-use/25/. (https://www.eevblog.com/forum/testgear/comparing-two-hp-z3805a-gpsdo-10-mhz-frequencies-for-lab-use/25/.) Otherwise lovely Counter.

Congratulations
I have the 53230A and it works like perfectly.

If you want to analyze some measurements, try the free software: "Stability Analyzer 53230A" that can be downloaded from Matlab Central here:
http://www.mathworks.com/matlabcentral/fileexchange/31319-stability-analyzer-53230a (http://www.mathworks.com/matlabcentral/fileexchange/31319-stability-analyzer-53230a)
It probably works on your 53220A as well.

Technically, I bought it last week, and it arrived on Wednesday.  Finally got some pictures posted.  It's a 1967 HP 3460B Digital Voltmeter (my nixie collection continues to grow!).  It has a broken nixie in the 3rd slot from the right, but I have a spare squirreled away somewhere around.  An operation and service manual is enroute courtesy of the 'bay.  I expect I'll start a repair thread once I get going on it.  (The Dymec 2401C I posted a few weeks ago will have to wait for the time being; it's still in CA as I didn't get a chance to pack and ship it before returning from my trip last week.)

Meter as received:

Traded for an HP 3456A. Stuck buttons making the display read crazy. Before I started pressing buttons, the display looked normal, so there is hope that there isn't much wrong with this. I need to take apart the front panel to clean and repair all the switches. I'm suffering thorough the flu, so I don't feel like doing too much right now.

The 3456A is quite deep, so finding a place for it will be a challenge. However, it will be nice to have another 6.5 digit meter to compare with my 3457A which was recently calibrated.

There is also a link to a video and some other useful tips in that post.
I have pulled apart my 3456A to fix some non-detenting (but still working buttons) and found some of the metal strips floating around the inside and some missing, I have just bought some spring steel strip to try to repair, no luck so far with a bit of steel tape measure (too stiff) nor stiff plastic. I bought 0.05mm thick strip (the same thickness as the springs)

This was a decent deal, $36 + shipping for ~ $60 total.  It works okay, but has a possible slight zero offset and some sort of oil was spilled into it.

Didn't realize so many forum members were watching that one. Looks like it's in pretty good shape. Much better than the listing description sounded. Congrats on getting it at a good price. :clap:

Whilst it may be more sensible to buy a budget station to start with, life is a lot easier with good tools and if the budget is there then why not. It'll always have a decent resale value.

True and it's also true that I don't know how much budget he has reserved for this.
However, the first soldering jobs we all ever made were not very good for the soldering iron. We all did some wrong steps and if you have a cheap soldering iron for the first jobs you wont be much worried about the iron's tip condition.

When learning, it is great to have the opportunity to use quality tools. That way, you learn how to do the job properly. There is time to fight the tools later. In other words, a really great choice! I wish I would have the chance/sense to do that more often when getting into something new.

I'm with KJDS and JuKu.  The soldering iron is one piece of equipment you will probably use a lot.  Get the best you can.  I believe you will develop your soldering chops faster and better if you start off with good stuff.  I learned to solder on firesticks and did OK.  When I got my Hakko 936, my skill grew quickly using the better equipment.  Now I have a Hakko FX-951 and Metcal MX-500 and my skill is improving even more.  If he has the budget to get the JBC, then that's awesome and I certainly would encourage him to get it.

While I agree completely with you, as someone having a JBC in my private workshop, there are downsides.
1. The tips are _very_ expensive. They'll last a good long time if you take proper care of them though, something a beginner might not do.  (Proper temps, cleaning and re-silvering)
2. You'll need another iron as well for the very large stuff. Even though the JBC has excellent thermal overhead, they cannot get around the physics of having a small tip.
3. You get spoiled...  Soldering at work is no fun anymore. I spend as much time swearing over their irons than I actually do soldering.   Go figure.

It all depends on how deep the persons pockets are. I (like many) began with electronics as a kid and my first iron cost about €15 (which I had to save for), but if the person has the resources, then there's no reason why he shouldn't buy this iron. It would be worse if he had spent big on an iron that's known to be bad. At least he did the research before he bought.

Like many it seems, I started as a kid. But as I got older (and had access to those that knew far more than I), I ended up buying better tools and haven't looked back since.  >:D

If you can swing it without excess financial pain, as far as I'm concerned buy the good one right off the bat.  Buy once, cry once.  Otherwise you buy the cheap one now, and then some time later spend more $$ on the good one, thus kind of 'wasting' the money you initially spent on the cheaper one.

Obviously this doesn't apply if you can't afford the good one right away (thus my financial pain comment above); in that case the cheaper one is better than not having one at all.  That being said, I can't think of a time when I've regretted buying the good tool over the cheap one if I was able to afford it.

I can't think of a time when I've regretted buying the good tool over the cheap one if I was able to afford it.
It is never a mistake to buy the best tool for the job that you can afford. :-+

The only caveat I would apply to that is if you have a one-off job to do, then just get the cheap tool (but don't expect it to last long or do as good a job!) :-//

Of course, as with everything else in life, there are many competing factors involved and you will have to make compromises to one degree or another. :'(

 A Canon MF624Cw color laser multifunction device. GF needs a printer and scanner for work, and I refuse to ever buy another inkjet device because I am tired of wasting money on print cartridges that cost more then the printer and dry out before you've used half of the ink. Huge sale, too. List for $350, Best Buy is selling them for $200. At the reduced price, replacement toners do cost more than the printer, but if you let it sit and not print anything for a few weeks it will still work fine. Also has a 1W sleep mode, which is pretty cool.
 Windows 10, love it or leave it, but by the time I was done connecting the printer to my wireless router, it was ALREADY installed and ready to go in Windows 10.  Had to use the supplied DVD for Windows 7, it did not automatically detect the printer like Win 10.
 Only negative, it's honkin' HUGE. Was fun getting it home - my car is rather small (BMW 135). Box wouldn't fit in the trunk. Or in the back seat. So GF climbed in the back (the back seats are there strictly for insurance purposes and VERY small children) and put the printer on the passenger seat.

Oh, you're gonna like that!   :-+  One of the best purchases I made for working with SolidWorks - it's sweet to be able to just twist and turn to move & zoom your model on the screen.  Very intuitive.  Though it was perplexing the fist time something (a cat in my case) rested on it and moved the model 50 miles off screen.  I returned from lunch to a blank screen, no model anywhere in sight.   :-//  I finally noticed that the little triad in the corner was in a bizarre orientation and hit the 'center the model' button and POOF it reappeared. Took a while to figure out what was going on until I eventually noticed a feline snoozing on the blasted thing and realized it was moving the model down, down, down...

NO DUPLEX!!

I'm with you on the ridiculous ink costs which is why I buy the stuff in bulk. I gave up on the Epson Stylus' and now my latest MFP device a HP 8610 I only paid £80 for with cashback is excellent. It will scan documents to a network share over WiFi. Duplex is brilliant. Especially with the booklet printing modes.

I am only annoyed about it spending so much of its time phoning home to report ink usage and send the salesmen on to me for their ink plans. Feck that - I will hack those carts just like I did with the Epson...  :-DD

I also have a cheap B&W laser which I know and love, my trusty Samsung ML-2010. I'm using cheap bulk toner refills on that, but I have to admit for nice high resolution PCB boards it may be worth investing in a proper cartridge (or better toner).

I bought mine from a restaurant that was remodelling, got 6 for $10 each. Simple chairs, but I like them, just had to use a pack of chair feet ( not couch feet, otherwise I would have had a lot from a certain Aussie bloke ;) on it's way to me) to replace the worn out ones. They work well.

Still learning so cant tell for sure yet, but certainly helps navigating schematic sheets, easy zoom/scroll. I have a feeling it may be of more value to CAD software rather than Altium, but as you said price is ok, so why not.

Very nice container... Though the  12oz Aluminum container to the right has double the capacity, and is way cheaper! Just have to consume it's contents first!  :-DD

Frustratingly, I *didn't* buy this recently: http://www.gumtree.com.au/s-view-details.html?adId=1065132580 (http://www.gumtree.com.au/s-view-details.html?adId=1065132580)
Computer Moniter 19 inch LG Flatron (L1953H)

It's identical to the monitor I currently use on my main PC. Old, nothing special, got it for free. 1280x1024, which suits most of my uses well. But most importantly, you can remove the stand and use it like a picture frame - bottom edge on the desk. I like that, and with most monitors you can't.

When using photoshop I'd like to have a second screen for the tools panels. So I searched hoping to find a 2nd one the same. Found that. But $40 is too much. People throw these old 19 inch screen out on the street. I offered $20, and the seller accepted. As soon as I asked for their address to go pick it up (Blacktown, a long drive), they retracted their agreement and wanted $40 again. Then when I refused, they tried to bargain up to $30.

Phooey. I've been waiting for another one to turn up, so far no luck. If I wanted to pay significant money I'd just buy a nice new big screen.

I recheck that listing now and then. I doubt it's ever going to sell for $40. I guess that person has never searched gumtree for 'computer monitor, show cheapest first'.

This arrived today from our favorite auction site.  It's in very good physical condition (though a bit dusty inside), but has at least a few issues as it's flakey on some ranges.  The serial number says it's from late 1966, and it was made in Great Britain.

I have the manual on order from Artek and will dig into it once I get the link.

Bought a couple of days ago:  3 Barred Rock and 3 Rhode Island Red chicks. Now I've got to build a coop. Then I'll have some related electronics projects: Automatic dawn/dusk coop door opener, coop temp monitoring and control, and maybe an electric fence controller to keep the racoons and bobcats out. Will put a PV panel on the coop's roof and tie it into my current nearby shed solar PV system to power the coop.

3D Space Mouse for my Altium. Lovely finishing quality.

I have a SpaceNav around here someplace...I used to use it for gaming in Second Life. I'll have to explore using it for other stuff now!

I got a whole pile of little stuff today...Adafruit dropped a box on my porch! But the best was the simplest, a pack of 357A button cells I ordered from Amazon for an old pocket multimeter I dredged out of the basement.

The meter didn't work when I replaced the batteries, but instead of tossing it and getting a new one, I decided if I tried to fix it and failed, then I wasn't out anything but the time, so why not?  I had the tools right to hand seeing as I was at my brand-new workbench, so I hauled out the magnetic mat and the Phillips screwdriver, and had at it. A few gentle pries with a spudger, and carefully removing a Jesus-clip from the range switch knob, and I had the board out of the case.

I didn't see anything really obvious, but it HAD been in the damp basement for years, so I used a fiberglass contact cleaning brush and cleaned the battery contacts and the range switch pads and wipers. Then I reassembled it, put in the new cells again, and VOILA!

Working like a BOSS.

Yay! I win! And the new bench helped!

Agilent 6553A 0-35 volt 0-15 amp supply for $70.00 shipped - powers on, maybe works, maybe doesn't. I will only know for sure when it arrives.

Received the supply today. It was well packed and in pretty good condition. I powered it on and it works. The only issue was both rotary controls just barely worked. I opened them up and gave them a quick cleaning. They both work perfect now. I am putting together a Keysight order and will get a replacement front knob for the current adjust, they are in stock and are only a few bucks.

Nice one, Pat. It appears that I'm developing a case of the Nixies. Bought a dead HP 5216A a little while ago. Then, a partially working one showed up. Grabbed it too. The latter one (picture attached) is running, but has an intermittent gate. Both duly added to my growing renovation queue.

Be very careful - nixies are insidious little buggers, and they WILL multiply.  Before you realize it, you'll be surrounded by them.  You tell yourself you can quite them any time, but just try.  Something with neon numbers will appear in your e-bay feed (or someone here will post a new piece of cool old gear that you haven't seen before) and before you know it you'll be off on the hunt again, and Brown Santa will be delivering heavy boxes containing little glass vessels of noble gas to your door.  Some are round and button shaped, some are ovalish with flattened sides, some look like regular tubes and still others hang from above like bats in a cave.  All are cool.  And addictive!  (And will swell your renovation queue.  I have one of those, too...   ;D)

I've got 34901A, 34903A and 34908A.

I'm not planning any automated test by now, but it was almost a 'score', about US$ 650,00 (with today dollar value) shipped (which, for our contry is a very good value). With the 3 cards, in a mint condition. It has the warranty until mid-2018. Some relays (majority) was never switched, looking in the memory logs.
So I bought to use mainly as voltimeter for bench tests.

I have two 5221As in the queue, that's how I know about the bat tubes.  I didn't know about the 5216A till seeing yours.  I had an evilBay search programmed for the 3734A after seeing it and the 3735A in a mid/late 60s catalog, and when one popped up I made an offer and they accepted.

I almost bought a 5221A and its sibling the 5231A. The ones I usually see are the 5-digit model (and one listing was missing the hp nameplate). The ones with the 6th digit option seem kind of rare. I look forward to seeing your restoration of the 5221A.

The first one I got (last year some time) is a 6 digit one, but it has a bad tube.  I recently snagged a 4 digit one planning to cannibalize it to fix the first, then immediately thereafter (of course!!) found a replacement tube for the first one.  I haven't gotten a chance to do anything to it yet, though.  I know I took some photos of the 6 digit one when I was working on it before, but apparently never uploaded them.  I'll see if I can find them later and get them online.  It had been hacked upon, and had some terrible soldering inside.

Last week I updated my DMM to a Keysight U1253B with the O-LED display. I've used a Fluke of some description over the years since Fluke first appeared way back in the 1980s. My only reason was because that's what everyone else used... As I've aged the eyesight has too and my go to meter, a 179 Fluke, has become harder to read at silly angles propped on the work bench... Anyway, so impressed with the U1253B and the fact I use an iPad and iPhone I ordered the U1117A Bluetooth adapter above which will link the DMM data into various Apps...

If you're only going to use it with iThings over short distances, the cheaper, all-orange U1177A would do just fine. It's Bluetooth Class 2 while yours is Class 1 with more power output. You'd need accompanying Class 1 Bluetooth device on the other end to make use of that feature. And yes, I don't know what they were thinking with these two model numbers; good example of practical trolling, if you ask me.

I got a bit stalled repairing a Keithley 616, and I wanted an electrometer, so I got something even older, a Keithley 610B!  Fortunately a former owner re-capped it already.
I expect the tube-based frontend is not as stable as a fet input, but it seems to work well and in areas I can verify (voltage and resistance) it seems to be in spec.

The 5886 electrometer tubes operate on practically battery voltages!

Yihua 908B soldering pencil with fume extractor line to replace the original one that came with the station (also pictured). I got this new from an Australian company (of all places) for roughly $22 USD. I had planned to rig up some kind of home-made vac and filter system, then I saw this at my favorite local electronics recycler....

a Weller WFE-2P "Zero Smog" Fume Extractor. They had it listed at $50 and, as always, I negotiated and got it to CAD $20 (~$15 USD). Works perfectly. The filters look fine, and given the small amount I will use it, I don't even know if I will ever need to replace them. This unit retails at about $1000 USD and a new set of filters will run me about $60. Combined with the 908B iron, I can now solder with nearly zero fumes. I still do plan to make a DIY large area fume extractor.

One of my favorite activities is shopping at local industrial surplus store and hunting for cheap surplus high quality caps as they become rare day by day since most of them are now invaded by those crappy Chinese brands.  :'(

This time is quite unique at least to me, as I spotted quite rare Nippon Chemi Con GXE series caps which is rated at 125C, and others ordinary low impedance like KY and KZH series.

I finally unboxed the LED shop lights I bought from Home Depot that arrived last week. I'm pretty happy with them. They're only 3 feet long, not very heavy, and rated 3200 lumens at 42 watts. In reality the one fixture seemed considerably brighter than the two F40-T12 tubes in my kitchen ceiling light. The picture is pretty bad I know, but it was kind of hard to hold the light against the ceiling in one hand and the camera in the other while standing on a milk crate.

We can't see what your meter is measuring?  Ohms?  K Ohms?  uSiemens?  There is a convenient glare right where the display shows the units.
It seems likely that you are measuring residual leakage from whatever kind of silly "noise filter" or "surge protector" components that may be inside.

It is 135 K Ohms.
I open the socket strip to see what is inside.Because it has one way screws, had to drill holes in screw.
Then i saw the circuit and i understand how it works.I have soket strip from APC and Belkin and all show  OL when i try to measure resistance between phase and null

Because they are just wires, no electronics.

I don't know why you didn't just plug it into the wall socket initially. It either works or goes bang. In the 2nd case you get a warranty replacement. Now you've drilled out screws etc, even if it fails you have no chance of a replacement.

 Realize also, super simplifying, that at 240V, have 135K across it is about 1.8 milliamps. At 120V, it would be less than 1 ma. That's nothing.

One of the common ways to drive detection on model railroads so that you can determine if a track is occupied or not is to detect current flow through the rails. With more modern control systems where the voltage across the rails is constant, instead of the old variable sort of thing where the voltage controlled the speed, this is pretty easy. A powered unit (with a motor) or anything with lights, that's obvious, there is a load in place. But for freight cars - what do you do? The common option is to put a resistor across the wheels. Most circuits for detection can 'see' with a single 15K resistor, but for reliability (wheels and track get dirty, etc), a more common value is 4.7K per car. I put a 10K resistor on 2 axles of each of mine (most US railcars have at least 4 axles) so it's about 5K per car. Now multiply by several hundred such cars (on our club layout, I will never be able to have that many on my personal layout). Yes, it finally starts to become a somewhat significant value, but when each power supply can supply 5 amps, and you have 4 or 5 of these driving different sections, so only a fraction of the total number of cars is drawing from any given power supply, it's no big deal. With a nominal 4.7k resistance, and a typical voltage of 15V, worst case is about 3.2ma per car. However, less than ideal electrical connections between the wheels and the rails increases the effective resistance. Say somewhere closer to 10K, unless you scrub the wheels and track and press the car down hard. So now we're talking about 1.5ma per car. Even with more than 10x the voltage, this circuit in the power bar is drawing less current than a model train car fitted for detection.  You could stick an equivalent resistor in an outlet (don't do this.....) and it won't even get warm. On 240V, it's less than half a watt.

Those 545A's are pretty cool.  I found a manual for them online.  I am actually working on an 8 channel logic probe with the fast signal detection that the 545A has.  It will detect a pulse as quick as 35ns (and faster but not guaranteed) and report it as 10 Hz blinking like the 545A.

It even has bios of the lead engineer for each tool - including the ME who designed the cases for them.

How often do the lamps fail and need to be replaced? Mine hasn't failed yet but I do wonder what the lifetime is for the little internal lamp.

Hmm.  My 7T11 definitely has problems.  I'm going to have to dig into the manual for it.  I was able to get some plausible X-Y action with a pair of both of my 7S11 plugins (one with a lesser sampling head), unfortunately that's not so interesting to me.

The 7T11 has a lot of exciting stuff, including a buttload of reed relays.

I doubt you need to worry too much about it, if it's survived since the 80s it's probably got a lot of life left still left in it.

Anyway, I have a weird old industrial dekatron counter I need to do something with.  (Something made more for counting events and turning a load on or off).  The power supply (uses a Sola ferroresonant transformer!) seems to be functional and the tubes seem ok.  I am tempted to think about reengineering it to be a digital clock.  Presumably if I can make some decades roll over early and build a suitably old-fashioned 60hz to 1hz divider :)

A guy contacted me after seeing an ad I had in a ham radio buy/sales site. Bought these today for around 20 $

FACIT PE1501 hi-speed paper tape punch (1964 vintage)

Siemens T.send 61B paper tape reader (50's vintage)

The FACIT one was one of the first tape readers in use in Denmark!

At last! A TRG 105C Photodetector. Quote:
Quote
The TRG 105B Photodetector can directly measure the power of Q-switched laser outputs. To obtain a response from DC to 1.25Gc, the photodetecting photosensor element, the bias supply and the coaxial connector are part of one homogeneous microwave structure. Unit has a rise time faster the .3 nanosecond, output of up to 70 volts into a 125-ohm load, a DC bandwidth to 1.25Gc, and an Output impedance of 125 ohms.

That was from a listing way back in 2002, which I missed out on due to dithering. See first two pics. It was only $49, but while I was trying to make up my mind someone else bought it. I've never seen another one since.

Till this one came up. The next later model apparently. Bought it for $40. Last 3 pics. It's in the USA so it will take a while to get here via my reshipper. Fingers crossed it isn't broken, though I notice it's missing the front diffuser.
Ha ha, I offered $25, but on Saturday and I don't think the seller saw that yet. He did drop the price from 50 to 40. I'm really hoping he didn't see the offer and choose not to respond directly due to the thing sounding like broken glass rattling around inside or something. I couldn't take the suspense, and can afford $40.

I've also had no luck in all that time finding any data on it. Can anyone help with that?

I'd say i'm covered for powering high load stuff now.

The fan's aren't that bad, i even think lower noise than my HP 6632B's.
But i haven't applied any serious load on it yet ... Well i don't have anything that could load it seriously.

No teardown yet , i have warranty on it.

Assuming you're fairly constrained on budget but you did want to reasonably load that power supply for testing -- That's when it's time to look around for suitable resistive heating elements in everyday life.  If you were living in the US, I'd suggest a 120V, 15A portable heater.  Another possibility is the replacement heating elements for tank-type electric water heaters, if you have those in your area.  I noticed that they're various sizes and starting at about US $15 here.  They're meant to screw in the side of the tank, so you'd need to put it in a bucket of water or something :)  Obviously you can get a rough sense of the resistance from the voltage and wattage rating -- it will change some with temperature, but not as bad as an incadescent light bulb.

Just use 2 kettles in parallel, they will provide a pretty good test load. Put water in them, and turn on to test. They will not get to boiling for a long time as the heater is being underrun.

Oh good grief. I bought one of those exact ones at an auction several years ago. I ended up giving it away because it "didn't work" and I didn't have the time to look into it. I guess I can chalk that one up to user error/stupidity. In my own defence, I looked for a manual online and couldn't find one, so I didn't know any better.

You could be right.  The copyright date in the manual is 1983 so the user interface would have been designed a year or two before that.

I don't think that much, a bit more DC accuracy 0.025% (U1253b) vs 0.05% (U1273A/X),
I was left with the impression from photos that the 1273 was bigger but looking at the spec sheets they are v similar.
The 1253 has a rechargeable battery - only 8hrs or so of continuous use but I have the habit of switching off between measurements (mostly) so it hasn't worried me. The leads that come with the 1253 are nice and supple , not like the U1282 (which is quite a bit bigger/heavier also)

Yes, it's not that big. Furthermore, it's curved in the right way - fits really nice in your hand. Would call it sexy, even, if only it didn't just feel wrong ;) The batteries last much longer than 8 hours. Unfortunately it takes 4 x AAA (hate those) but rechargeables do work just fine.

It's a long story. Condensed version: There's a lovely spot in the bush near Sydney with 3 generations of family history.  Has a great swimming hole, that always (since at least 1900) had a large fine white sandy beach on one side. This is due to the way flood current flows - it goes down one side, hits a barrier, curves around and spreads out, dropping carried sand on the beach. Floods get about six to eight feet deep. Back around 2002 the area had a severe bushfire; surrounding hills up the entire valley were left with bare ground. Then in the next few years there were some severe floods - high rainfall plus the rapid runnoff. Result: three huge rocks washed down the river and wedged, just upstream from the swimming hole. In subsequent floods the result is the pool's current swirl is absent, replaced by a sharp jet that cuts across the back of the beach and is working on cutting a channel through the downstream barrier that forms the pool.  The beach is already mostly gone, and each flood cuts more away, including from the bank.

So, I'm removing the wedged boulders. Once they are gone the flow will be as before, and the beach will gradually rebuild, though it may take a long time. Decades? 100+years? Doesn't matter.

The largest boulder is the size of a big car. I wish I'd seen that flood, it must have been pretty spectacular.
Yesterday was my third rockbreaking trip there, the small and medium boulders are now gone, and I've started on the big one. Mostly working with rock-splitting wedges and small mallets, but that 14 lb sledge really makes a difference for stubborn bits.

I call it Molly. Like Thor's hammer Molnir, but the Aussie version. "Oh, you don't want to break? Have a little chat with Molly. She's very persuasive."

Please, no 'helpful' suggestions about explosives, jack hammers, crackamite, or anything else that can't be used in this location for multiple reasons, including legal and logistical. I've already been through all that on another forum. If I had a way to manually drill deep holes in the big rock at any decent speed, yes, crackamite or 'feathers and wedges', would save some time. But everything has to be carried in, and it's over an hour's walk, some off-track. First trip my pack was 30Kg, yesterday with the sledge and some other stuff it was 26Kg. And even with present methods around half the work is carting the rubble away and tidying up. The aim is to leave the site pristine, as if the recent boulders were never there.

I'm doing a time-lapse photo-series. After the rock-moving work is finished I'll post it.
Couple of pics below are the final stages with the medium-sized rock. It was already much smaller than its original size. Gives a good idea of the amount of work in cleanup too. All that rubble is now moved, though only to a temporary intermediate location. First priority was to get it out of the flood stream-path, otherwise it could get washed into the pool in a flood.

Just received some goodies for my new man-corner ;D
Two 120x60cm rubber ESD mats for on the bench.
Grounding box
Some grounding leads and a wrist strap
ESD safe brush and cans with IPA and contact spray
Solder fume extractor
PCB holder

The box of the fume extractor had me worried for a bit. I knew it was a cheap unit (about 50 EUR), but when the box needs to remind you that it's "100% high quality" you just know all bets are off and you just start praying the thing actually works. Surprisingly enough, it actually feels like a decent product for the money. The arm is mostly metal and feels like it should last at least a couple of years plus it has a decent reach. On the top of the fan you can attach one of two included pieces. One is an adapter that lets you attach a large air pipe/tube/thingy. The other one just redirects the air in one of four directions. The housing at the end of the arm is plastic and has an on/off switch. The fan itself has a metal housing and plastic blades and it simply runs directly on mains. It seems to displace a decent amount of air without being excessively loud. It's just a standard fan so it should be easy to replace it with something of higher quality. Although this one as QC PASS written on it, can't beat that  :P My only complaint about this unit is that they didn't route the wiring through the arm even though there are guides all over the arm for that.

The PCB holder is a piece of garbage. Lots of plastic and most of it is warped. At least it can hold a couple of small screwdrivers...

 Hmm, the fume extractor mounting on a swivel mount is interesting. I just have one that sits on the desktop. One the swivel, I would probably outfit the inside of the intake with a ring of high brightness LEDs and have it double as a lamp, since it would nearly always be pointed at the work area. Plus I'm already putting my monitor on a mount like that to free bench space.

Yeah, that's the first fume extractor I've seen on an arm like that. Pretty cool. I like your idea of adding lights to it to do double duty.

I have no clue who the manufacturer is for that fume extractor. It's made in China, but the labeling on the box and unit suggest it comes from the Czech Republic. Also found this: http://www.tipa.eu/cz/odsavac-pajecich-zplodin-zd-153a-antistaticke-provedeni/d-135395/ (http://www.tipa.eu/cz/odsavac-pajecich-zplodin-zd-153a-antistaticke-provedeni/d-135395/) The webshop I got my unit from must've imported it from there.

The idea of mounting some LEDs crossed my mind as well. There's plenty of room around the intake for some LEDs. Maybe those 12V LED COB's I have in my parts bin will fit  :popcorn:

I call it Molly. Like Thor's hammer Molnir, but the Aussie version. "Oh, you don't want to break? Have a little chat with Molly. She's very persuasive."

Funny enough today I gave the nice new handle on "Gentle Persuasion" it's second coat of clear varnish. Now to do a third coat next week, then it will be in service again. Did not put the wedge back in, but used epoxy instead to make the fit a near permanent one. The black is not paint, but a phosphoric acid etch I did on the rust, and the shine is the remaining varnish on the brush from the handle work. Will not last long in use, but still, gives it that "new look" and for the moment it looks nice. Should have ground off the edges a little, but they are minor, just showing that it has been used a little.

Now it will join the collection sharing a space with the 3 4lb hammers I have. Why 3, sometimes you need a small anvil, and often you need a backing to whale on something, and having 3 means the anvil can still be in place on the small stuff. Plus i had them at home one day and needed some percussive fitting, so went to the hardware 50m away and suddenly had 3.

A beefy mosfet from IXYS in sot-227. or minibloc body.

Secured it from esd by connecting all pins with copper wire to prevent it getting zapped by accident.

This should be "adequate" while in handling period before connecting to the real circuit, right ?

Those Ixys parts have pretty good on board protection already. Remember the operating environment and the general installer putting one in is often a very hostile place.

Reminds me of getting my first MOSFETS, which came in a TO18 package with a small copper wire wound around all the leads and the case for protection. I used a 3N199 (IIRC) as a logic gate to do some switching, running it off a 30V rail. Used some 4M7 1/16W resistors as gate voltage dividers and protection.

Was thinking of oiling it, but while I do have the oil, the varnish won out because of the quick application time and ease of use. Could not put the wedge in, the fit between the head and handle is too tight, I was using the head to put the handle on so the epoxy as a helper was perfect, plus filled the top nicely as well. As it is only used when I need either a portable anvil or to destroy something I think it will generally hold out.

Yes, good fittings and easy to use. Here however having exposed external brass fittings means they will go the first night into the scrap guys grasping hands, who will rip them off just for the brass. Same with aircons, you mount them at least 6m up or higher, and run the copper pipe inside the wall to stop it being stolen, and also put a massive steel frame around the unit so they cannot easily get it to rip the copper out.

Here the similar fittings are all plastic, and you even get all plastic fittings including taps that go with it.

These IXYS mosfets are very hard to kill.  That should be plenty adequate for protection.

If you don't mind my asking, what type is it and what to you plan to do with it?    I ask because I have about 80 IXFN200N07 and 17 IXFN106N20 mosfets that have been sitting in a box for many years.  The 106's were samples I think at a previous employer.  I got the 200N07's because that same previous employer thought that mixing batches decreased reliability of their motor controllers, which used 6 per controller, so whenever they found the date code about to switch with less than 6 left, they just set those remaining ones aside.  I nabbed them one day when they were cleaning the parts room.  I've thought about listing them on eBay or new Tindie Flea Market section, but never got to it.  When Digikey still sells the 200N07's for $26 each, I feel like I should do something with them or sell them, but they have been sitting for probably 15 years or more...

Got an old Associated Research Hypot Junior 2500 VAC hi-pot tester.  Totally not something I need, but it was being sold cheaper than I've expected to see such.

Verified that the leakage indicator turns on around 500 uA with a 1 M ohm resistor, turned on around 500V.
Then verified that USB chargers sold by Apple and Amazon test to 2500 VAC without leakage.  On the other hand, a cheap non-safety-certified wall-wart starts leaking at only 750 VAC.  We have a winner.  :clap:

Technically, yesterday, but better late than never.  Snagged some RF stuff at a swap meet - some SMA unions and r/a connectors, filters and attenuators, and a few BNC feedthrough terminators - three 50 ohm ones, and one 600 ohm.  Also got a pair of Tektronix generators - a type 106 square wave generator and a type 191 constant amplitude sig gen.  I was surprised to discover that both are hybrids with both tubes and transistors, and are from the mid 60s.  I'd have guessed they were mid 70s at the earliest.  Surprise, surprise...

It turned out to be a banner day for manuals - got a bunch at the swap meet and then more at the surplus place later.

Tektronix seemed to use GR-874 connectors for almost all 50 ohm stuff in the 1960s.  (and maybe the 70s, at least for stuff that was an old design.)  I have a nifty Tek amplitude calibrator, 067-0508-00.  One of the center conductor fingers was broken, and even though I have GR-BNC adapters, it's more useful to me with BNC, so I replaced it with a BNC by using some suitably sized washers jammed in the panel-mounting hardware for the GR connector.

Yeah, until I got these, I was unfamiliar with the GenRad style connectors.  A hermaphrodite RF connector - it's a very clever design.  I don't have any, and of course a few hours before buying the Tek pieces, I bought the other connectors, attenuators and whatnot from a guy at the swap meet.  In conversation, he mentioned having gotten a bunch of the GR connectors from a surplus place in San Diego that had closed.  If I'd known I'd be getting the Tek generators later in the day...  Oh well.  I figure I'll look into replacing them with either N or BNC jacks, as I can easily get adapters to whatever I need for those.

500 volt mosfets...

I've been thinking for a long time about taking four of my IXFN200N07's and screwing them to an old CPU heatsink and fan to make a 200 amp H bridge.  Thing is, I don't really need a 200 amp H bridge for anything right now.  :)  I still want to try it.

Building a dummy load would be a better project.  I suppose the IXFN106N20's would be better for that since they are 200V.  The 200N07's are only 70V.

£199 from Amazon. I tried shopping around and even using flubit for an attempt at discount but no chance. Originally given a one month lead, that passed and another month added on.

Clearly selling like hot cakes - they could charge a fair bit more if they wanted. I think FLIR have been taken by surprise with the sales of the android version.

Not a purchase, but a dumpster find: Acer H5360HD Projector. Looks like new and all the major bits work, just the remote is faulty. No it's not the batteries, it's not transmitting anything, which is an issue with this model because there no control buttons on the unit itself.
Not sure what I'll do with it when it's fixed though.

Most IR remotes that go faulty, the LED has lifted from its pads and just needs re-soldering. A quick test for IR remotes to determine if it is faulty rather than the receiver is your phones camera. If you see the LED lit up on the phones display when pressing a button the remote is most likely ok. I've had remotes with a permanently lit LED as a fail mode, but most often it is just extinguished.

Post by: McBryce on May 03, 2016, 10:30:21 am
Yes, I already did the phone camera trick. The IR LED doesn't flash. Inside is just the typical µP with a transistor / resistor to drive the IR LED. The LED looks well soldered, but I'll connect a scope later to see if the transistor is still doing its stuff. There's not a lot more that can go wrong really.

Just watch out - the main camera lens in an iPhone has an IR filter so this test will not work. The user-facing selfie lens will work okay though.

Do I really need another power supply?... Yes, yes I do.
Everybody needs another power supply.

There isn't such a thing as "Too many power supply".

It is the same thing to say, you have too many DMM....

That's like money: you can't have "too much money".

I say sometimes to my girlfriend that you can't have too much boobs or too much money. To my lab friends I say that you can't have too many lab tools!

That is very odd. So you have at least 20 oscilloscopes? Or are you an Imelda Marcos and we are talking 1000+ ?

* My dad was into it when I was young, which seems to have inspired an interest. Sadly, it seems I was also the reason he got out of it.  |O Cost at the times I've looked into it hasn't helped in my case either, though perhaps SDR will be what finally pulls me in.  :-//

I cold use that money for more food, or even just use it later on for gas to get a a job instead of school. I think that would be more efficient.

I wanted to make a scope clock for my desk at my new job.  I was originally going to build all the circuitry for a little old round electrostatic CRT, but then I got to looking at small, low-bandwidth scopes.

Got a good deal on one of these.  Aside from the dead NiCads (removed and leakage cleaned up) and unobtainable power cord, it works fine (uses only a couple watts at 12 volts!)

Now I just need a microcontroller and a couple 8 bit DACs driving it. :)

I built one with a PIC24FV16KM202 - they have dual 8 bit DACs and are buffered so that they that can be simultaneously written. You can buy a 5V Microstick with the part on it and an integrated programmer/debugger, part number DM240013-2

I also wrote an asteroids game for it.

Isn't he saying that he's got a photo of a scope? ;) That reminds me an online auction platform scam happening here few years ago where some crooks where "selling" people photos of a brand spanking new, latest and greatest smartphone model for the price of the actual hardware. The description was carefully worded in a way that it wasn't technically deceiving but when some poor overly-excited, anxious fellow wasn't paying enough attention, he was convinced that was the real deal and promptly handed the money.

Other time, I've seen ad addendum to an auction listing for a non-functional phone dummy, as the ones sometimes used on shop displays. He had to explain to the dumb bunch who was bidding like crazy one over another, quickly reaching the price of a real phone, what a freaking DUMMY means :-DD

If you don't zap yourself at least once on something with tubes, you're doing it wrong.

My first zap was off a tube radio chassis I paid 20p from a jumble sale for. I had no idea the chassis was live.

Well, the tube part of the FT-101 is the final tubes, so it's a bit higher voltage than an ordinary tube receiver.

Personally, I haven't really accidentally gotten myself with a serious high voltage jolt since I was a kid with a strobe-light kit that didn't have a bleeder on the main capacitor.  Everything else has been tiny tingles or zaps from harmless stuff -- the strongest in recent memory was the time I tested a good electric flyswatter on my knuckles!

Got two rather grungy General Radio 1454-A Kelvin-Varley dividers.  Both seem to be fully working.  One (bottom) that I did some cleaning of (including cleaning off the contacts gently with a contact cleaner that leaves poly phenyl ether lubricant behind -- some googling told me not to use silicone, but the original was just an ordinary grease) improved its functioning and accuracy.  I'm a little disappointed that I started to take some paint off, but it was already in pretty rough condition -- I'm not sure if products like Goof Off (or other xylene products) can be trusted now that CARB made them add acetone to it.

 A 5M reel of 5630 LEDs, power supply, mounting clips, and remote control to add some lighting to my bench. Experiments with the less bright RGB string I have now leads me to believe these will be PLENTY bright to light up the work area. Funny thing is the supplied power supply is not enough to light the entire 5M, if the current spec is to be believed. No worries, I will only be using about 2-2.5M worth. I'll buy or build another power supply for the string I want to put under the bench to light up the floor.

I bought a proper bench power supply. Dual tracking with a fixed 5 volt third output. It's exactly what I used to use at work. Seller was a liquidation auction seller. Sold it as is, but I saw from the pictures that the meters and LEDs didn't look wrong, so I took the eBay gamble, and for $70, I got a supply that tests perfectly in every way! Truth is, I have dual tracking supplies on my bench already... It's just the little 400mA peak current limit on my Tek 500 series modular kit is just not enough power. Last month, I hit that current limit four times... It just wasn't enough.

Hot air rework station. Nuf said. How I have lived without this baby is beyond me. I don't even care that it oozes Chinese cheapness...
"Must to keep the handle on the holder, Before to turn on the machine!" That sticker will NEVER come off. It gives me a laugh every time I see it!  :-DD

The soldering iron option cost me $8 more... I question the value of that $8  ::) The tip is crooked. Seriously at an angle. I thought it was broken... The heating element is just... not straight.  :palm: That said, it works. I'll save that cheap iron for times when I need to abuse an iron, like when I want to melt some plastic things together. Save my REAL Hakko irons for REAL soldering!

I also bought a new printer to replace my old HP from 2006. Now I have a good laser printer that has toner and doesn't streak. I'll give my old printer credit for lasting as long as it did. Still technically works, it's just low on color toner, and streaks sometimes. New printer was cheaper than toner for a printer that might still streak anyway.

Now I can print PC board patterns to transfer to copper clad board (for etching), as well as print meter scales and other stuff like that. Also, apparently these things are great for printing paper documents too! Who'da thunk it!  ;D

Mine was from the latest batch and it seems like the backlight whine has been resolved on my unit anyway. It's nice having a meter that takes common batteries, guilt-free backlight use with some eneloops wooohoooo!

Sure, the spacing is the same in both directions and all 4 terminals are connected with this short.
You have to use it for zero check and calibration for all sophisticated Agilent meters.

I wonder if there is something on that short PCB, like maybe the tracks are laid out in some fashion that requires the directional short with the indicated HI and LO positions? I can recall the Keithley version is laid out pretty much as a "H", maybe this one is more of a "U" IYSWIM?

I love the capabilities of 7000-series scopes, but I hate how cruddy some of the overly-complicated switch mechanisms have gotten with time.  My dream would be the mechanical aspects of a 500-series with the capabilities of a 7000-series.  But now that I have two 7000-series scopes, it's obvious I don't have any common sense.

Sounds like the high accelerating voltage is arcing-over and then recovering.
I would first check all around the CRT neck and where the high-voltage wire connects (if it is externally?) and make sure everything is really clean,
Dust, grime, etc collecting on the envelope of the tube (or around the high-voltage circuit) will create a path for high voltage to arc-over.

Yup, I'll second that. Arcing on the HT. It may just be damp dust, but check for cracks in the HT cable insulation too.

One seems to just work (didn't do a full performance check yet) and has a noisy fan.  The other as some self-calibration error on startup, a dead rotary encoder, a strangely loose front panel, and an even noisier fan.

At least EBM-Pabst generally still makes the fans that fit these era HP instruments.

Is that the pair of them that I saw on the 'bay a couple of times?  Fingers crossed that you get two working ones when you're finished.  They're surprisingly LONG, aren't they?

Maybe.  I sniped both of them on the same day, and still spent less than 2/3 of what I usually see them go for in total.  They're certainly no longer than my 5342A microwave frequency counter - the one that works best may get stacked on top of it.  It seems I'm acquiring quite a few transistor-era boat anchors.

Post by: Cubdriver on May 12, 2016, 10:34:04 pm
Ahh.  Not the ones I was thinking of, then, and perhaps it was even another instrument rather than the 3314a - somebody had a listing for a pair of them.  And boat anchors are a fine thing (IMO) to collect.  If you got both for less than 2/3 of what one ordinarily goes for, I'd say you made out well.

Hopefully I'll be able to fix the capacitor on my old 15"Macbook Pro (according to Louis Rossmann) and give it as a gift to my girlfriend.

I just received this in the mail.
It is a diamond tipped hole cutter drill bit that can be used to make isolated pads on a copper clad circuit board. It is usually used for drilling holes in glass, ceramic, etc.

This drill is 5/16" (8.1mm) outside diameter and 1/4" (6.3mm) inside diameter. It will create 1/4" pads. Other sizes are available if you want other size pads.
This drill is made by DiamondSure and can be found on eBay for about $15.

They don't look like a bad little unit for around $400AUD or $290US, available down here from Bunnings or Masters (don't go to Masters FFS), If you didn't already have a milling machine, pedestal or bench drill then these might be a valid option, the base table looks very nicely machined in another video and they are bit bigger than I thought they were.

Random Youtube video and there are plenty of others.

Not really something I bought, nor today. But I finally got around to testing the crate full of transformers I got from a colleague a few weeks ago: all 40 KGs of them, none of them have specs on them  :scared:
Some are crap, some are useful, one is scary: comes from a microwave oven (I guess) and has a 3.5V and a 2500V output, yikes.

Also visited that big Swedish furniture store. Got a new chair, a nice drawer that fits under the bench, and a load of clear plastic crates for all the other parts.

Yes, on multiple occasions  :-\ Still beats having to go shopping for clothes, visit twenty-something stores, only to end up back at the first store to finally buy something  |O Just picking my fights here; can't win'em all!

Anyway, back on topic. Got a bunch of MC4 connectors for my PV installation. I messed up while crimping one of the connectors and I can't get the damn thing to come apart. Still have quite a few meters of 4mm2 (11? AWG) cable left over, might be useful for some nice beefy test leads  :-+

I like the bar display on that bench meter. As nice as digital is, sometimes, you need a fast reacting visual reference to work by, and when you need it, rapidly changing numbers will NEVER do. I wish more meters offered that feature.

The 1970s era high speed photodetector finally arrived, after a longish sit at the US reshipper.  US40 on ebay, plus about Au$60 shipping to Oz. (It's heavy!)
Teardown pics here: http://everist.org/NobLog/20160519_1970s_hs_optical_det.htm (http://everist.org/NobLog/20160519_1970s_hs_optical_det.htm)

Still to check if it actually works.

Anyone know where I could obtain 5 to 20 meters of RG63 125 ohm coax cheaply? Initial googling only finds bulk suppliers.
Cables with GR connectors already fitted - even better.

Also, any suggestions for constructing an optical source that can generate pulses with rise and fall times of 0.5 nS or better?

I have a similar RS bench meter. Mine is the 22-175 version. They're pretty useful. I bought mine a long time ago and paid around $99 for it. It was a big upgrade for me at the time because all I had until then was a Radio Shack 43 range analog meter. The 22-175 had capacitance measuring which was really nice to have. It worked fine for years until I dropped one of the leads on a laser power supply board and 3000 volts zapped it. The capacitance measuring still works though, just nothing else :)

I've got a 22-175A myself.  I bought a box of stuff from a family selling granddad's stuff after he passed.  There was a bunch of other stuff in the box and it cost me $20. 2 sets of leads cam with it and after a cleaning of the battery contacts, it works just fine.

Yes, I agree that the listing price is more than fair but it only takes one or two bids to blow it out ridiculously, mind you if you look at overseas listings the price is in the ballpark but they are certainly not in this condition, I was also drooling in regards to the other stuff we didn't see, a bit of a tease really.

That cheap Keithley 2010 from Australia, which was a topic here some time ago:
https://www.eevblog.com/forum/buysellwanted/ebay-%28aus%29-keithley-2010/ (https://www.eevblog.com/forum/buysellwanted/ebay-%28aus%29-keithley-2010/)

Offered him even less, I think it was around 550 Aussie$ + 50A$ shipping, which equals to 420€, which is a slightly high price for a K2000 or K2015 here in EU. Works great and already like it, so perhaps I won't sell it soon :) 1000V range is slightly low though.
It has '98 Nichicon caps in it. Will probably change them before it gets ugly inside.

Also bought a MAHO MHC 700P vertical milling machine for about 4k€ delivered. Wanted a good milling machine for a long time, finally got one for a reasonable price. Machine is in quite good mechanical condition and has a very nice table.
Unfortunately the spindle slide (Maho calls it z-axis, would normally be the x-axis) doesn't work in the forward direction yet. Already found the schematics for the x/y/z axis motor controller. Will probably start by swapping motors of z and x or y axis, thereby I can see whether the problem is on the motor/relay/end switch assembly or in the electronics.


Also need to dump all EPROMs of the Haidenhain TNC-135 controller, when I'm done with the z-axis. It's quite old, and unfortunately somewhat limited in functionality (e.g. can't mill a circle), but it is good old 1980 technology, thereby should be relatively easy to keep in operation. Will probably start a repair thread, when done.

 Came home from my business trip to Las Vegas to find my EEVBlog Bryman DMM has arrived. Pretty quick to the eastern USA (Pennsylvania).

My newest meter. Everything else I have is early or late 80's vintage Fluke.

A reasonably stable if dangerous DC voltage source so I can check the HP 3457A which will be arriving soon against my HP 3478A and Racal-Dana 5001 on the 300V range:

(Yes, I break them into smaller strings when left unattended!)

It isn't a good 9V battery sting until you made some SC sparks  :popcorn:

High Voltage DC-DC Boost Converter 5V-12V Step up to 300V-1200V

also High Voltage DC-DC Boost Converter 3V-5V Step up to 200V-620V available.

I found it on eBay no problem.  Used "High Voltage DC-DC Boost Converter 5V-12V Step up to 300V-1200V" as the search criteria.  There are others, but I like the look of this seller:

http://www.ebay.com/itm/High-Voltage-DC-DC-Boost-Converter-5V-12V-Step-up-to-300V-1200V-Power-Module-/201472584304 (http://www.ebay.com/itm/High-Voltage-DC-DC-Boost-Converter-5V-12V-Step-up-to-300V-1200V-Power-Module-/201472584304)

I especially appreciate the inclusion (at no extra cost) of "self-healing insurance".   :)  For $3 more the seller will 3D-print you a case with a "full toxic configuration" (see near bottom of listing).  I don't think that word means what he thinks it means.  :)

The blue 1.4 version seems to have some useful lower voltage taps and "self healing insurance" is still there (resettable fuse?)   :)

No toxic case with this seller though!

It has a 300-1200V main output using a diode cap multiplier. But notice there are taps at 170V and 200V which should be good for Nixies. A 75V AC and 50V DC too.

My test equipment collection has grown yet again - I snagged a Tek 515A scope, and an ancient Triplett Model 1210 Tube Tester (more because it looks like it will be kinda cool cleaned up rather than for any practical purpose; it's from about 1936 or so).

Scope:
(https://photos.smugmug.com/Electronics/Tektronix-515A-15MHz/i-xSTdz9P/0/L/Tek%20515A%20front%20panel-L.jpg)

It has in interesting serial number (apologies for the blurry iPhone pics; I was too lazy to set up the good camera):
(https://photos.smugmug.com/Electronics/Tektronix-515A-15MHz/i-nR8S44T/0/L/Tek%20515A%20serial%20number-L.jpg)

Unfortunately for the scope, some miserable prick bastard opened it up and pilfered all of the dual triodes out of it,   |O |O so I'll need to come up with (9) 6DJ8s, a few 12AT/U7s and various others before I can test it.  I suppose I should be grateful that they didn't strip it bare, but it still peeves me as any calibration it may have had went away with those tubes.  I hope their speakers blow!   >:D 

There are a few more photos of the scope showing the dust & empty tube sockets along with a quick overview video at https://pmanning.smugmug.com/Electronics/Tektronix-515A-15MHz (https://pmanning.smugmug.com/Electronics/Tektronix-515A-15MHz)


The tube tester at about 80 years old is in rather rough cosmetic shape, but I think the panel will clean up nicely with some elbow grease and various cleaners/solvents.  The enclosure will need to be re-covered to make it presentable as a good bit of its outer skin is missing or peeling up.

I wonder if 'instigator' might not be a more appropriate term.  Finding cool stuff on here that others have has certainly prompted many an ebuy search and subsequent injury to my credit card in my case...  Martin and Robrenz (immediately off the top of my head; there are certainly others as well) manage to inspire the urge to collect and refurbish things.

@Cubdriver, Pat that Tektronix looks a beaut, the internals are easily fixed relative to the front panel (I think) . The front panel on that scope looks immaculate. Can't wait to see it in action.  :-+

I bought what I thought would be a 'donor only' unit for my other FT-101 but this unit I think is too good to hack to death, I have the tubes it is missing and found the knob missing on fleaBay (wasn't the same seller though!!!) This unit still has the protective plastic on the front panel - I think it will have to go.

Currently am battling my way through the HV section of my, new to me, Tek 453, definitely one dead HV diode (non-thermionic) and maybe more, so am getting a few spares in before I tackle it too much.

Watch out for those 453's - they don't breed but they are demonic. Mine had a bag full of things that had been sacrificed to it. Mostly FETs, tunnel diodes and "driftistors" as they ended up being called. Make sure it doesn't steal the organs from the insides of your other scopes in the night. The cat pissed in mine in the end and exorcised it permanently.

Nice score.  :-+ You must've done something right in a previous life.   ;D

It's an inert, fluorinated fluid used for vapor phase soldering (digits in the P/N is the boiling point).

There's an entire thread on it here (https://www.eevblog.com/forum/projects/vapour-phase-soldering/msg590795/#msg590795) if you're curious.  :)

My tweezers from Aliexpress finally arrived. A decent shipping time for such a complicated customs department as Brazil has. 9 bucks for the entire kit including shipping.

I can barely buy two tweezers with that much money on some Brazilian electronics online stores, 23 more electronics orders to arrive from Ali.

Spent some time on Saturday, and most of this afternoon completing the board layout.

then this evening I Just spent over ZAR700 (about a tank of petrol) with ITEADSTUDIO
for 10 off 10x10cm Prototype PCB's
Most of the cost was for the DHL shipping.

I just couldn't wait 4 months for the standard shipping.

Now I have my fingers crossed that they will arrive in 2 weeks!

I just bought this air compressor.

8 bar, 2L tank (no oil), 1100W, 1,5 hp, 195 l/min.
It is really loud, but useful when I need to remove dust from some old dirty, dusty and sometimes crusty boards, fans, computer cases.
I paid around 120 euros, it may be a lot, but now I don't need all tiny - and too expensive - air dusters (aerosol sprays).

It's not that expensive if you consider that a can of Air-duster will cost about €10, so 12 cans (a years worth in my world) costs the same. So after 12 months you're saving money.

I didn't have high expectations of course, but it's much worst then I thought... the software in particular. The actual frequency is half of what you choose, the menu system is really stupid, it's reaaaaaly slow, etc etc...
I wonder if anyone ever wrote better firmware for it? I tried to find it here in the forum with no success, but I didn't have many ideas on how to search for such thing.

My SMD rework station arrived ! :D
It used to be made by a company called Toyo here in Brazil but for some reason they transitioned to this new brand. Even when I bought it at the webstore it was still named as Toyo. It pretty much pairs up with Hakko from what I've read on Brazilian forums.

Just tried them on some SMD resistors and caps, they only got stuck due to some solder residue I believe. After it cooled down I picked them up several times and they always dropped down once I let it loose. For that little money, a good deal IMHO.

The resistive epoxy paint will slow the drain rate if you have a charge built up, and use the tweezers without strapping in first. BTW, that stuff comes in colors too. 8)

But so long as you resistively ground yourself first, any strictly metal object in your hands will be ESD compliant*.  ;D 

* Metal handled brushes, such as an acid brush, require a liquid on the bristles to complete the path to ground as it's not metal all the way to the business end (no conductive strands added to the animal hair as they do with the black plastic handled ESD brushes that aren't 100% synthetic fibers).

I recently did some math on how much modern computers cost, and the conclusion was kinda absurd.
Supposedly, i could get a computer than would be 0.75x as fast as my current $2000 rig from 2009 for just 0.02x the cost.
Naturally, i couldn't quite believe it and went looking for a catch.

Didn't find any, and ended up with 4 computers' worth of cheapest second hand components i could find, and some spare cash missing.
Ended up making a nice box for them, which triples the computing power i have at home.

Where did you get LGA1155 mini-ITX for $40 ($2000 * 0.02) with some sensible IvyBridge CPU?, RAM and so on?

I could believe that even an old SandyBridge (2011) could be almost as fast as a top machine from 2009. Unfortunately, not anymore. Moore's law grinds to a halt when it comes to CPUs so current top of the line Skylake is not massively faster than top of the line SandyBridge or IvyBridge? Skylake is likely to be more power efficient though.

I wouldn't expect much raw computing power from your setup. It is cluster like, IO severely limited by the gigabit ethernet (!= InfiniBand) and it is CPU only. Good for some specific workloads, distributed systems, but not real GFLOPs. If you want real performance the code needs the fastest possible access to data (caches, local SRAM, DDR memory worst case) and preferably a GPU. For example if you want to do deep learning training then there is not much point of having anything else than a couple of nVidia GTX980 or Titan.

The nice thing about second hand computer parts is that they work exactly as good, but cost a half to a third of the new one.

The new price came out to something about $80, the second hand price was between $30 and $50 per board (CPU, board, Fan, RAM)
I already had a bunch of PicoPSUs and DC-DC converters (the whole thing runs off a 24V bus i have) laying around, so that trims the cost as well.

CPUs are G1610, G2020, G2030, G1620 - low-end Celerons and Pentiums with 2 cores each and 2.6 to 3.0 GHz.
Core to core they are 1.5 times as fast as an i7 920 running at 2.6GHz, but the latter got 4 cores and HT, putting it ahead.

Depends on the task. Right now i do raytracing experiments on it, which needs about zero communications, and the speedup is 3.75x the i7 alone.
Another thing i tried is magnetic field computation, which is also a zero-communication task.

Naturally, such tasks can run a thousand times faster on a GPU, but the GPUs are somewhat awkward to program, have limits in complexity and data size, and don't come in small, low power consumption and low cost packages.

In the end, it's not intended to be something practical, but just a for fun experiment driven randomly.

A variety of local sources of the "garage sale" and "direct advertisement" kind.

Not always. You need to be careful with gaming hardware. If the mainboard of CPU was aggressively overclocked by the previous owner, it may not last as long as you expect.

Post by: McBryce on June 09, 2016, 01:58:40 pm
Actually that's a typo, I meant "mainboard or CPU".

Eitherway, my main worry is that many OCers raise the voltages to get the CPU to run stable at higher frequencies. This can cause all sorts of problems that only become obvious later. I've also seen CPUs that were brown on top because they had been running extremely hot for the majority of their life. How much life is left in a CPU after that?

Yes, most time Made in Japan means high quality, but also means you will never find their schematics  :)

Nice meter. It looks brand new, so I suppose no mini-teardown to look under the cover?  ;D

I'm looking on ebay for Keithley 580, but somehow these things go for crazy prices. This Hioki looks nice, but it is even more expensive :)

Why not? I will do the mini teardown.

BTW, this meter is not that expensive as you think, it took me 83,000JPY, cuz it had been listed as "for parts or repair"  ;D

You got a really good deal on this meter.
It has some amazing specs:

0.01 µ? to 1.200 G?. RS-232C, RS-232C Printer, USB, and GPIB interfaces.

Can perform resistance measurement with a 6.5-digit, 1,200,000-count display at a maximum resolution of 0.01 ??. It delivers more than enough capabilities to be used in applications requiring high-resolution resistance measurement, for example in testing inverter motor windings.

High-resistance materials such as conductive sheets and conductive rubber are often used in electronic components. The RM3545 can measure resistance values of up to 1,200 M?. It also delivers maximum accuracy of 0.006%, enabling researchers to test state-of-the-art current sensing resistors.

Auto-scanning and step scanning
When using the Multiplexer Unit Z3003 to perform scanning measurement, you can select either step scanning or auto scanning depending on the test conditions. Auto scanning is convenient when you require only an overall judgment result at the completion of scanning, while step scanning is convenient when you wish to generate judgments in real time using the instrument’s EXT I/O interface.


Congratulations.

Yes, the seller's has listed all his item as "for parts or repair", but this one he put "maybe new" in the title, and there were pictures shown it's new and working great  ;D

"for parts or repair" is the new "as is"

I've seen some other sellers do this as well. They just don't want to spend any time on the items and don't want them back, so they list everything "for parts".

You can find Service manuals for these online, they are a classic old meter especially with their 2.5kV ratings.
I've got a few of them including a later AVO 8 Mk 5 that has a 3kV range.  :scared:

I'm really happy I bought this meter. It's got so much more weight to it than my Simpsons. I've spent some time today cleaning it. The BR121 15V battery was dead measuring under 6V no load. I didn't want to spend close to what I paid for the meter for a new battery, so I bought 5x CR2032 3v batteries for $5 and made a small battery pack for the meter. Works perfectly. I didn't want to modify the meter so I just soldered it onto the battery tabs, easily reversible!

Yep those 15V batteries are ridiculously expensive.  :--

My fix was similar but with 5x LR44's and some copper tubing cut to make the same length as the 15V battery and all covered in shrink sleeve and it fits in the meters battery holder just perfect.  :-+

Not exactly today's purchase, however, a 7410 arrived which enabled me to bring this Racal 9835 back to life. I purchased the Racal a few weeks ago as a restoration project. It has obviously not been used for several years but the calibration is spot-on. Now that it works I can turn my attention to tarting it up. When the nixies are in the case there is a filter which gives a nice red glow.

(7410 = old school TTL chip, triple input nand - none of your modern low power rubbish :) )

Nice, I got one at a local hamfest for $10 but it didn't have the bag. It's OK for a basic meter.

Leather case is easy to restore provided it is not too badly cracked, using just a tub of Dubbin, or saddle soap if you want to keep the hard finish.Dubbin on the strap though will make it soft again and stop it cracking further.  You just use a thin layer on the surface and leave an hour or three then gently work it in with a clean cotton cloth.

Technically, I bought it two weeks ago and it got here last Friday, but it's taken me this long to get the pics uploaded and labeled.

More nixie goodness courtesy of everyone's favorite online wallet lightening site - an HP 405CR.  It's a three digit autoranging digital voltmeter; this particular one was made in late 1961 based on the date stamps and serial number:
(https://photos.smugmug.com/Electronics/HP-405CR-Digital-Voltmeter/i-FN5RStC/0/L/HP%20405CR%20front%20high%20oblique%20as%20received-L.jpg)

It was not well packed and sustained some shipping damage (the rack handle sitting atop the enclosure was attached when it initially went into the box, but a good hit along the way overwhelmed the screws and they failed in tension), but miraculously arrived relatively unscathed all things considered.  I plan to start a thread in the repair section in a few days once I get some time to start digging into it.  No, power hasn't been applied yet - need to check out the filter caps and rectifiers first.

It seems kind of bizarre to be working on a digital voltmeter that's full of vacuum tubes!

Additional pics and a quickie iphone video are in the gallery at:

Hi Pat,
That looks great! More Nixie envy. Such a pity some people don't pack at all well. So much can be lost but it doesn't look too bad from the photos.

I had to laugh recently, one of our real tube guys at our radio club, (you can say a tube part number to him and he can tell you about it! he worked for Phillips when they made electronic stuff in Adelaide  http://www.philipstorr.id.au (http://www.philipstorr.id.au)  )  was giving a presentation about restoring old radios, he is very brave and tackles ones with serious rust and as he liked to put it "the rulers of the universe" had visited, (he is a great fan of 'Hitchhikers' Guide to the Galaxy'    i.e. mice)

A quick look at my recently acquired HP 5221B has one Nixie (MSD) not working, not sure if it is the tube or the driver, not easy to get to, the tubes look v hard to source.

Don't forget to post the progress!

Thanks!  Yeah, got a bit of a queasy feeling when I picked up the box, felt the meter shifting around loosely inside and heard the clunk/rattle that the broken off handle and loose cuffs were making. Thankfully, it's nowhere near as bad as it sounded/I feared.  Good thing HP used to build them like tanks back in the day!  It's a crying shame that Keysight apparently no longer does, based on blueskull's recent experiences!  Ugh!

Well, the good news is that the tubes (on mine at least) are socketed, so it's easy enough to switch them for testing purposes. 

The bad news is that they're a bear to get to (as you've already apparently figured out); due to the way it's constructed you basically have to take one of the cast Al side frames off in order to remove display window - it slides out to the side.  If memory serves, it should then be possible to disengage the little plastic nubs that retain the main board and slide it out to the front enough to access the tubes.  (The top lid must be off as well.)

The worst news is that those funny little upside-down bat type nixies seem to be about as common as hen's teeth. Mine had a bad one as well - it would sometimes light off - and it took a few months of waiting before one turned up on ebuy.  I'll dig and find out what part number(s) I had in the ebuy search function - I think it goes by several different ones.  I should probably extract the counter from the pile and put the new tube in it before the replacement goes astray!  I have to wonder if something like your nixie resurrector would do any good for the weak tube I have - might be something to cobble together and try out.

I just realized I never posted the pics of 5221; I'd started labeling them and getting them ready back when you got your counter but then saw a bunny and went off chasing it before finishing.  <edit> Or maybe I DID put them up but managed not to see the gallery there.  D'oh!!  Here's the gallery link in case you didn't already look at them:  https://pmanning.smugmug.com/Electronics/HP-5221A-Electronic-Counter (https://pmanning.smugmug.com/Electronics/HP-5221A-Electronic-Counter)   I'll get them up later </edit>, and perhaps start a thread on the counter in the repair section.  I don't know how far into dismantling it you've gotten, but perhaps they'll help you a bit.

Yeah, Sphere had been my first hope too, but as you see it was a bust.  I was eventually able to get a replacement on the 'bay, but it took some patience.

Bummer that they're no longer easily available.

Technically, I bought it two weeks ago and it got here last Friday, but it's taken me this long to get the pics uploaded and labeled.

More nixie goodness courtesy of everyone's favorite online wallet lightening site - an HP 405CR.  It's a three digit autoranging digital voltmeter; this particular one was made in late 1961 based on the date stamps and serial number:
(https://photos.smugmug.com/Electronics/HP-405CR-Digital-Voltmeter/i-FN5RStC/0/L/HP%20405CR%20front%20high%20oblique%20as%20received-L.jpg)

It was not well packed and sustained some shipping damage (the rack handle sitting atop the enclosure was attached when it initially went into the box, but a good hit along the way overwhelmed the screws and they failed in tension), but miraculously arrived relatively unscathed all things considered.  I plan to start a thread in the repair section in a few days once I get some time to start digging into it.  No, power hasn't been applied yet - need to check out the filter caps and rectifiers first.

It seems kind of bizarre to be working on a digital voltmeter that's full of vacuum tubes!

Additional pics and a quickie iphone video are in the gallery at:

And now that it's way past time for bed (so much for some quick photo captioning!), it's time to crawl off to hit the sack for a while...

I recently got a 405 as well! I absolutely love it! Mine is the A version. It was in very rough shape when I got it. I did a very slow power up on a variac and all the electrolytic caps were OK! There was next to nothing on these beautiful meters online other than some HP literature.

Yes, I remember seeing the thread you started back when you got it, and just revisited it.  It cleaned up very nicely!!  I'm planning to attempt to re-form the caps before powering mine up and am hopeful - I've had reasonable success with HP caps thus far, as long as they aren't dried out completely (one in my 3439A meter) or don't have internal connections that have corroded open (one in a 3440A meter).  My fingers are crossed that these will come up and not require restuffing.

You're correct regarding the dearth of online info on the 405, though I have found an operating/service manual for the C/CR version in the HP archives website:

http://www.hparchive.com/Manuals/HP-405C-CR-Manual.pdf (http://www.hparchive.com/Manuals/HP-405C-CR-Manual.pdf)

I'm not sure how close this would be to your 'A' model, but if you haven't yet seen it it may be of some help.  Unfortunately, it doesn't have info on the decade counter/displays themselves, but treats them as black-box parts.  I haven't done any searching thus far trying to find info on the decade counters, so I have no idea what may or may not be out there.

Recent purchase from the local Goodwill thrift store.  Auto Stac 1500 VA voltage regulator - also works as 110/220 V step-up or step-down transformer.

I happened upon this and couldn't pass it up for only $10.  I don't need the voltage regulation but can use the 110-220 step up capability.  Also, I was curious how it works and wanted to open it up.

Hooked it up to my variac and it works well. By pushing the input up to 130V I can get the output up to about 230V for step-up use.

Yeah, exactly. Fun watching the servo work while I change the input voltage.

It's got one heavy hunk of toroidal copper.

I've heard of people using these in 3rd world countries with poor grid regulation.  Not sure how this came to end up in a US thrift store - especially with the Euro plugs.

People immigrate here from all over the place. If it's a CEE 7/16 Europlug, perhaps the prior owner lived in Cuba and needed the step-up for some 220V devices. The voltage regulation was probably handy as well.

That's a good question, but I'll bet the Euro plugs helped you to get such a great deal on it - they had NO idea what it might be.  Regardless, a cool piece of kit.

The Stabilac equivalent was common in a lot of remote area Radiocom stuff in West Oz,back in the 1960s.

TV  & Radio Broadcast Tx sites used their VERY big brothers to stabilise the 3 phase incoming.
They had a crank handle you stuck in the top .
To test if they were working,you cranked it a bit off the correct setting,& it would motor back to where it should be.

Electrolytic and ceramic caps kit, trimmer kit, test probes, transistors kit, zener diodes kit (not shown), Xilinx Spartan-6 FPGA development board (which I forgot to buy the JTAG-USB adapter for notebooks), Mastech Multimeter (posted a few weeks ago).

I'm quite happy with this new addition to my lab, even though I had to pay a sh... stupid load of taxes for somes items, but that's how Brazilian customs works.

I think if there were any question as to my sanity (or, more precisely, lack thereof), it's been definitively answered it today.  I've officially lost my mind.   :palm:

Just bought an HP 740B DC Standard/Differential Voltmeter (described as 'used, cosmetic damage, powers on') and then an HP 4270A Automatic Capacitance Bridge ('doesn't power up, no means to test') on evilBay today.  :o   Both from sellers I've dealt with before, so I'm reasonably confident that they'll be packed better than the poor 405CR was.

As usual, I'll post pics in a week or so when they arrive.  Now I have to head off to my NA (Nixies Anonymous) support group meeting...

I used a banggood coupon and got one of these plus an extra tip. For scale I put it next to some familiar objects in the last photo. My cheap Asus power adapter has a stiff, heavy cord that's a bit clunky, so I'm thinking of making something light and flexible from silicone wires when the 2.5mm plugs that I ordered come.

This works way better than my cheapo YiHua. It comes up to temp in under 10 sec with the power adapter I use, has configurable low temp standby and sleep timers, wakes from sleep when moved, etc.

Just because I'm lazy...

How much for that and where you bought it Sbampato12? I struggle with desoldering stuff, have been thinking about getting one of these. Is it good?

I've bought from a friend, used. I paid R$ 400,00. I didn't used yet. But I will before next week.

"Doctor does it get better?"


Robert

Damn you, Robert - you're probably going to wind up costing me MORE money!!   :scared:   :-DD

I've looked at the uTracer a few times after first seeing it a few years ago on audio forums I'm on, but I think at the time he didn't have a kit and I wasn't that ambitious.  This potentially changes things.  Keep me (us) posted on your progress and results - as a tube guy it's something that definitely piques my interest.

And no, it doesn't get any better - at least (in my experience) not so long as you continue reading forums like this, ARF, DIY Tube and DIY Audio, etc.  As soon as you clear one of your evilbuy search terms by getting whatever it is, someone posts something else that you look at and say "Cool!!  I want one of those!!" and you're off on the hunt once again.   |O  Having old HP catalogs on hand to thumb through is not helpful, either, as I find they inspire searching as well.    :palm:

Well....   :-[  Truth be told I actually usually only clear them when I go to add another and it tells me I can't because I have too many active searches.  At that point I'll go through and delete one or more of the ones for things I've gotten already, but that's about the only time the list gets any pruning.  The reminders that pop up are more likely to be only very briefly glanced at or sometimes outright ignored once I've gotten something I was on the hunt for, but they're still there...

This just came.
I used a banggood coupon and got one of these plus an extra tip. For scale I put it next to some familiar objects in the last photo. My cheap Asus power adapter has a stiff, heavy cord that's a bit clunky, so I'm thinking of making something light and flexible from silicone wires when the 2.5mm plugs that I ordered come.

This works way better than my cheapo YiHua. It comes up to temp in under 10 sec with the power adapter I use, has configurable low temp standby and sleep timers, wakes from sleep when moved, etc.

Is it good to solder small electronics and wires? I've seen a few time ago that iron but I was affraid that it wasn't that good and ended using my good old uncontrolled mains connected iron...
Small electronics and wires are no problem. The toughest I've asked of it so far is soldering 16awg into big fat banana plug/jacks for test leads. It handled that much better than my Yahua did.

How is that spacenavigator? Checked pricing and its only 100e, thinking to get one, using altium with touchpad is pain in the arse..

Still learning so cant tell for sure yet, but certainly helps navigating schematic sheets, easy zoom/scroll. I have a feeling it may be of more value to CAD software rather than Altium, but as you said price is ok, so why not.

The more i use it with Altium the more i like it. With time it becomes natural and intuitive. I use it in 3D and 2D modes, even to scroll/zoom in Acrobat PDF reader. I think it is a great tool for a hundred bucks.  :-+

I did make sure i have copies of the drivers for all platforms (PC/MAC/Linux), people seem to complain the manufacturer is known for making older drivers unavailable as they introduce new hardware.

Seems to work fine on all ranges I have tried. There is a hand written note on the bottom that it was reading 0.3% high on the 100 mv range, the note is dated 18 Sept, 1988. I had a quick peak inside, I see some chips dated 1973.
The meter is very clean inside and out. There is an "Environment Canada" asset tag on the back so we know who has always owned it. It was listed for $50.00, I offered 25, they countered with 35 and I countered back with my original 25(I know, rather cheeky of me) but I really only wanted it for fun. Now that I have it here I think it is probably worth a little more then I paid.

Well I have received a near instant decline when trying it before. I always add a note with my offer - in this case I said I could only justify the 25 because I was buying it purely for fun. I also said that if it wasn't enough I understood. I'm never trying to make anyone angry and I never mind if they don't accept. The offer was good for 48 hours and with a few hours left the seller accepted. I guess they had no other offers. It may have helped the item was located in Canada. A lot of American's seem to avoid auctions in Canada so every now and then I actually buy something in country.

It is looking like all ranges are giving stable readings that look to be correct but I haven't verified what % error it might have.

You handled it well. Once or twice I felt that a higher price really wasn't justified. I may give it a go in a similar, well-explained manner, if the situation ever arises again. Definitely don't want to annoy the seller during negotiations. Thanks for the pointers.

Sounds like a really good find you have there.

 on ebay.  Seller had it for "parts or not working", I took a chance and offered $88 (+$22 shipping).   It looks and works like new, even the calibration is near perfect.

Not sure if I would pay the $500+ street price, but I like it.  My only issues are that it powers up with the outputs on -- no good reason for that at all, and the 4mm jacks are just junk.  Output is exceptionally clean, virtually no overshot, fast current limit kick-in, nicely designed course/fine controls and totally silent operation, there's no stink'n fan!!!


[Clarification:  The 1739 boots up in the last (saved) state that you left it in.  If you turn the output off, wait 3 seconds (the stated time to save changes) then power off the unit it will boot back up with the output off.]

Post by: Cubdriver on July 01, 2016, 06:17:03 am
So the output on/off switch on the B&K is a 'soft' key rather than a switch that mechanically latches, or something that sets a condition that the supply remembers when turned off and back on again? That seems like a poorly thought out design.  (Seems you think the same.)  I wonder what the thought process behind that decision was...

Otherwise, nice looking supply.

I've been on a bit of the retro kick lately.  Picked these two up in trade for an early 2000's Sony amp that had sat on the shelf for about 10 years.  The Leader scope's power button was broken (at the switch itself, all the way in the back) and it was covered in solder splatter, both were quickly remedied and it looks/works great, just need to clean the knob contacts on Channel 2 and it'll be a flawless little 50Mhz 2 channel CRO. 

The power supply works somehow, but there's a HUGE burn and the remains of a resistor on one channel and the remains of an exploded diode on the other.  Had a close look and someone's jerry rigged it so that current limiting and voltage regulation work, but now the OC protection spikes it to negative voltages and the fine adjust knobs have some odd behavior.   Luckily, the original manual was included and it has a nice legible schematic.  Gonna restore the original circuitry and see how she does.  Looks to be a re-badged Lodestar 303d, dual tracking 0-30v 3a.

Exactly.  It nicely says "OFF" on both displays when the output is off, but powers up with the output's on.  If you hold in the ON/OFF button (briefly) while powering up it will startup in the OFF state.  I was thinking about embedding a little processor inside that will do just that.  If you hold in the ON/OFF for more than couple of seconds on power up it enters the calibration mode.  This allows you to calibrate the supply using just the front panel controls.   It also talks SCPI so that's another way to potentially solve this issue, by remotely controlling the ON/OFF setting.

Yeah, passively cooled linear supplies are the best. Since most of the gear in my lab is fanless, it makes the others seem really loud when I need to turn them on.

Regarding the output turning on by default, perhaps there's a setting to change that? Might even be only via SCPI.

Not sure how finding stuff lying around is in the spirit of the title of the thread but ok, if it makes you happy :)

Not giving you flak but some pros and cons:
Pros - atx psu cheap, various voltages, high current ouput
Cons - no current limiting, relativley noisey
Title: Re: What did you buy today? Post your latest purchase!
Post by: Falkra on July 03, 2016, 12:26:49 pm
And no programmable voltage. But for the price and modification effort, it is quite handy.  :D
If you need more current, get a server psu, those are not really expensive, and can deliver tons of Amps.

Cons - no current limiting, relativley noisey
And usually regulated on a single rail, which got me to stop using that kind of PSU for projects...

A few binding posts... I found in the back of a closet and I was bored...

I'm sure I'll get a little flack for it, but hey, it's a $5 power supply with 12v, 5v, and 3.3v rails and OC protection.  I'm sure I'll find a used for it from time to time.

Don't knock it. It certainly looks a little better put together than this

An industrial equipment elapsed hours meter on a PSU is fairly unique I imagine.

Was going to post this in repairs, but since I just got her and already posted a pic here I thought I'd update in this thread.

So after replacing 1 of the 4 2n3055's, replacing the toasted resistors (3), replacing all of the 104z ceramic caps (4), running some bodge wires to replace the traces that had blown off the pcb... SHE WORKS PERFECTLY!  (Except for the blown LEDs that indicate separate or tracking modes, but they were hot glued in and i can see the damn switch right below them!  I'll get to them eventually LOL).

All in all, about $7 in parts and this old girl is purring again!

Oh I guess I suppose I should give credit to another new addition as well... picked up a DER EE DE 5000 LCR, which I put to good use identifying all the dead components (well, the ones that weren't obviously toasted anyway).

Please do so, somebody may be very grateful in the future when they find your repair thread.
A few inside pics and a blow by blow commentary would be neat.

Well, after more than seven months of monitoring ebuy, I finally found and snagged a reasonably priced copy of the POH (Pilot's Operating Handbook, aka operating and service manual) for the HP 2402A integrating DVM that I snagged on my December trip to California.  Now I just need to get the meter boxed up and shipped home (it's sitting on a shelf out in the CA facility) on my next visit.

I was beginning to doubt I'd ever find one - IIRC I've seen perhaps one or two of the manuals listed for sale, but the sellers thought they were printed on gold leaf or something.  Unfortunately none of the usual suspects (BAMA, K04BB or Artek) have copies and it seems to be a relatively rare meter so there are probably not all that many copies floating around in the wild, so when one popped up for $20 OBO I jumped on it.  This one should be cool to play with - it's an interesting looking piece of kit with a lot of stuff crammed inside.

It's very clean and working well, last calibrated in 2009 (B13 version, build on 2007, 3 on cal counter), spot on my dmmcheck. But some wear display..  :-//

I buy a plastic bench kit, clean the item and Now I'm waiting for Tektronix to send one new display to me..  ;)
With bench kit, display, pomona test leads, and chinese kelvin leads... Total about 600 euro spent... not cheap, but.. Good item..

I'm looking for a Agilent 53131a in good shape, but in ebay they are too expensive for me.
Also looking for a cheap/for parts Agilent E4418B .. but not luck..

My ZUP20-10 has arrived. In good shape, with thick dust. This thing has been sitting new in box for 9 years.
Being NOS, it was sold to me at only half Digikey price. Still not a cheap PSU, but it should be quite reliable, as any other TDK PSUs, despite the fan is quite annoying.

9 years in storage? Unless they used top notch capacitors, I'd consider replacing them before you use it.

When I worked at Loral Corp that was one of things we had to make, I made my own and my mentor examined it and found it to be skillfully assembled. Next we put it on the network analyzer and it was deemed good enough.

I would recommend anybody who owns an SA or a selective volt meter to build one.
You know what is in it and know not to subject it to anything it cannot handle.

Hey Boffin, do you have a link to the CC/CV module vendor?

How does it perform? OK?

It looks like a nice way to upgrade that 3rd PSU on my bench.

Post by: boffin on July 10, 2016, 05:20:29 am
The module is DPS3003; about $20 on Aliexpress. 

up to 30v (with the right input), 3A.  I'm only feeding it about 14v, good enough for the digital stuff I do.  Previously I had mod'ded the the same PSU with a 7805 to give it just fixed 12v and 5v, but I found myself doing 3.3v stuff occasionally, and this is also nice having the meter on the front.  Accuracy isn't perfect, but +/-5% is good enough for me (I can hear Dave shuddering at that statement)

The only thing I don't really like is it's click through for each digits, I'd rather just have velocity sensitive.

Be careful if they are no name Chinese made, they can ruin your SA connectors. I'd not go for anything other than a known brand because of assurance of mechanical precision.

It is not connector bandwidth which is a problem but mechanical precision of the mating part, i.e. Depth, thickness and protrusion of the pin or socket. I too use RFSupplier but only and only for prototyping, with Chinese on Chinese connectors.
A good practice is to buy a brand set of saver connectors (male-female one piece adapters) and use them on the equipment to minimize risk of damage of front panel rf connectors.

No, these let through DC, however, my SA is a DSA815-TG which can supposedly take up to 50VDC on the inputs, (well above what I will be working with), so it shouldn't be an issue. However, I may build myself a DC block for future use.

Regarding "ruining the SA ports due to mechanical inaccuracy", they will be mounted via a not-so-cheap SMA to N-Type adapter, so they don't have a direct connection to the SA.

The tuning will be ADGBEADGBE, from 27.5Hz to 1661Hz (28th fret on high E string) without any pinch harmonics or trickery! Extended range? Yes :)

The neck is 31×27.5? fanned frets to help get the appropriate tension across the range.

Logic Pro 8, to replace my old Logic 8 that got stolen :( Along with some 3.3/5V FTDIs as I had everything in the same bag so didn't have any more of those either, and a couple of ESP8266 modules to play with stay up to date.

Now I've gotta learn how to use it.  :scared:

Great!  I've been looking at the Siglent for a few weeks.  I'm looking forward to your comments as you navigate the instrument.  My old 2710 circled the drain a few years ago and I have been wanting another SA.  From your previous posts you seem like just the guy for the job.
Good luck

Ha, I'll need it.

Been away for a few days so I've had little time to fiddle with it as yet, only just with an simple loop probe next to my cell phone....900 MHz for my cell provider and 2.4 GHz for the WiFi no problem.  :-+

Keep an eye on the https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/ (https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/) thread
There'll be no way I'll challenge rf-loop in technical understanding or ability with these "black magic" instruments.

BTW welcome to the forum FuzzyOnion.  :)

This may be an 'electronics only' section, not sure - but after a long specification process. My custom 10 string guitar build has started!
...
The tuning will be ADGBEADGBE, from 27.5Hz to 1661Hz (28th fret on high E string) without any pinch harmonics or trickery! Extended range? Yes :)

Do you play that instrument like a guitar or like a chapman stick?

Like an extended range guitar. Maybe a bass if it's appropriate :)

A local distributor in the country I currently am in (Switzerland).
The fancy ones are this: https://www.adafruit.com/product/2821 (https://www.adafruit.com/product/2821) , seemed the best I've seen yet for versatility/ease of playing with with the serial interface built in, the battery supply and lots of I/O.  The other one is the bog standard ESP-01.

I buy mine from fleabay - I have not had any bad modules yet. (More than 50 purchased over the last year.)
ESP-07 modules mostly. Less than USD3 each.
Plenty of resource material on ESP8266.net and ESP8266.com.
It is a great device. I am having a huge amount of success with this device.

If you want just to start in a few ESP8266 prototypes, search for D1 mini on ebay/aliexpress. That's a nice little board that has a USB/Serial IC on it and it's breadboard friendly.

ESP-07 from seller horizon_electronic
These are the ones I buy:

ESP-07s from seller flyfuntech2014
These are the ones I buy:
http://www.ebay.com/itm/282100185487?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT (http://www.ebay.com/itm/282100185487?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT)

I have started buying the ESP-07s because my application requires very low current (battery consumption) and it saves me desoldering the LEDs from the standard ESP-07 module.
The ESP-07s is also a smaller form factor, however external antenna only. My application requires external antenna anyhow, so not a problem.
The ESP-07s is about twice the price of ESP-07 though.

Note: The ESP-07 and ESP-07s are not breadboard friendly as they have a 2mm terminal pitch.
It is not difficult to solder solid wires on to it and spread them out to fit a breadboard if you need to.
I designed a small (simple) breakout board for my R&D purposes, but I see there are commonly available boards on fleabay now.

So, Sears screwed the pooch...again...
About a month ago, I posted here with a pic of my new mower, a Craftsman Pro series 5.5" turn radius 46" power steering hydrostatic machine.  Nice enough.  Bought a 2 stage snow thrower with it.  Guys behind the desk swore up and down it would fit.  Took it all home.  Guess what.  Snow thrower didn't fit.  Not a chance in hell.
Not only that but the deck wasn't level, one wheel wasn't tightened down, an oil drain plug was loose, fuel line cracked and broke on the third run.
Gave up, took that piece of crap back directly.

Went out a local mom-n-pop hardware store today and picked up another new mower.  Can't put a snow thrower on it, but the price was right, "Pop" came out and made sure it operated correctly.

(I did look like a drunken sailor until I got the hang of steering it while under way, though :-DD - best to hold one tiller bar steady and control direction by moving the other slightly back and forth as needed.  Move both only for gross turns, not for course maintenance.)

Fluke 87V for $140.

Did AutoHOLD + VDC and it shows firmware 3.00.  Not sure if that's an older one or what, but my phone didn't do anything weird to it.

Already used it quite a bit, and I really like it.

HP 8656b signal generator... for no reason other than "I didn't have one." 

Have to say,  a bit pissed off that the seller sent me a different one than pictured even thought the listing specifically stated item was the one pictured.  Despite that hiccup it's spot on and fully functional and only cost me $150.  Now I'm trying to decide about kicking up a fuss and getting my money back or just moan about misrepresenting the item in the feedback.  The issue is if I send it back I run the risk of yet another bait and switch and may end up with one not nearly this functional/decent of shape for so cheap.  Pretty sure the dude was just sour I won his nicest one for cheap so he sent me what he thought was "fair"...  man I hate ebay sometimes.

I'm very pleased with the bridge. The outside of the instrument is a little beat up (scratches, small dents, nothing spurring for a ex-military instrument). The case did protect the instrument. I did clean it a bit, but it really didn't need much! It also appears to be dead on as far as measuring capacitance goes. I didn't really try measuring anything else with it, as I only plan on using it for capacitance anyway. I did pay a little over $100CND for it with shipping and import duties, but for the condition it's in and especially in working condition, I think I did alright. I did take it out of its case, and every tube including the magic eye are RCA!

I think it can measures 43M times per second, and the resolution of  each time could be 25ps.  :D

If there aren't any serious issues with it, I'd probably opt to keep it and moan in the feedback. Although you're well within your right to push to get the unit that was pictured, the seller could still leave you short in many ways, including making you send back that one, then claiming the correct one is no longer available and cancel the transaction. I wouldn't take the risk nor go through the hassle. You got a great deal. Of course, if you're not happy with it, I'll go the extra mile to relieve you of the pain and suffering at that price! :-DD

Not a purchase but an unexpected find on a dumpster dive. A very rare opportunity (at least here in my country) to found something so valuable that would even cost a few thousands of peso for a brand new one. Its an Hioki 3256-50 Multimeter. Its was dead but turned out to be the only issue was the board wasn't held by one of the clip post that has been bent for a long time since the board popped out. A simple board cleaning, re installation and reinforcing the bent clip post with a piece of paper fixed the issue..now I feel great to have additional multimeter to play with. :-DMM

Electrically is a different story.  :-BROKE Upper DC volt ranges won't calibrate. AC volts is totally FUBAR. It's stuck on over range. Ohms is OK. Oh well.

Just some DRAM, to upgrade a couple of PCs. 8 x 1GB DDR2 2RX8 PC2-5300E 667MHz DIMM.
They are ECC, but far enough behind the size curve that they were quite cheap. Au$12.20 for 2.

The module is DPS3003; about $20 on Aliexpress. 

up to 30v (with the right input), 3A.  I'm only feeding it about 14v, good enough for the digital stuff I do.  Previously I had mod'ded the the same PSU with a 7805 to give it just fixed 12v and 5v, but I found myself doing 3.3v stuff occasionally, and this is also nice having the meter on the front.  Accuracy isn't perfect, but +/-5% is good enough for me (I can hear Dave shuddering at that statement)

The only thing I don't really like is it's click through for each digits, I'd rather just have velocity sensitive.

Just got an email from them, and they have a new module coming out.  Looks similar, but it has a separate regulator board w/ fan, and supposedly up to 5A (although I wouldn't run it at that).  If you're building yourself a small powersupply, this would work nicely.

I am now working on power over fiber based on multi-junction silicon PV cells (the wide band gap InGaAs/GaAs/Ge rubbish won't work).
Luckily I saved up for enough money to buy a fusion splicer, and I have access to a clean room (crude fab with silicon/SiC/GaN/GaAs capability).
After this power over fiber project I will probably move to fiber medium lasers, focusing on short wavelength, for direct power device firing.

Is this related to your power inverter project? That would be very cool.

No. It makes no sense to use fiber to drive a 600V device. It starts to making sense when the bus voltage goes beyond 10kV.
I'm now working on a 6.5kV SiC module, then it will be extrapolated to 10kV. We also have groups working on 12.47kV distribution level solid state xfmrs.
Since I am going to patent this, no more technical details will be revealed here.
I didn't continue the inverter project since it takes my time, and it does not contribute any new knowledge to the society.

sorry to contradict you here. Fiber optics do make sense below 10kV.  Fiber optics are used for example from 3.3kV and upwards in motor starters to fire the thyristors to isolate the HV from the control. Even in a 690V module with IGBTs it would make sense to use fiber optics if those modules were to be cascaded on top of each other, for example in  a CHB architecture to handle several kV.
6.5kV SiC modules are expensive and not every manufacturer offers them, whereas 1700V igbts....

x ray generators, by design, don't supply continuous power, just during the exposure time which is usually less than a second. 'mAs' is the time by current parameter, important in radiography.
Usually you have to "prepare" the exposure which charges some capacitors, and then that hv pulse is generated within the selected parameters.
Also, if you want the system to generate this voltage you'll probably have to fake a current, the filament current, which is a wound coil found inside the tube.
Lastly, dont open the HV tank, as it either will contain nasty oil or nastier Sulfur hexafluoride.

Was a bit of a joke, but the manual for this thing does state it's capable of exposures adjustable from 1 second to 99min and 59 seconds in 1 second increments... Again really have no experience in this type of gear, but certainly seems like a legit amount of power... Lol

Yea, I couldn't really believe it and had some doubts as to it's condition.  I'm pretty sure it had gone unseen by most of the punters as it was listed as a 33210a, hadn't a single mention of the option 001 upgrade (which was a pleasant surprise when I opened the box!), and only had a single picture of the unit from a distance. 

Forgive the super budget counter it's plugged into, but I've got a decent Philips PM6666 on the way (another pretty solid deal at $150) that just hasn't gotten here yet!  (a tiny bit off as my cheapo counter doesn't actually have a ref in!)

Try writing on black ESD reels. White (TiO2 based) inks do not usually come with fine tips and strong adhesion. Darker pens won't make readable result.
Put a white sticker on it first. Still quicker than a label  ^-^

I expect sellers offering IC's to comply with industry standard ESD protection and insist they do. You should too.
How else to you train these sellers to supply IC's at minimal risk of arriving damaged.

Message to seller:
I require all static sensitive devices to be supplied in anti static packaging.
Failure to do so will result in no return business from me and no referrals to my friends of your products.

I bought a control panel for a larger television video switcher (Grass Valley "Zodiac")

(http://i.ebayimg.com/images/g/PLoAAOSwqu9VAza5/s-l1600.jpg)

The top panel includes dozens of lighted pushbutton switches and lights displays and "T-bar" faders.
Underneath are a couple of power supply units (probably wired to be redundant for "hot-standby")
And some sort of a controller computer, complete with a 5-inch floppy drive(!)

(http://www.salesbaron.net/BTpics/MLZ1967.jpg)

Judging by the labeling on the buttons, it came out of KING-TV, channel 5 in Seattle (NBC)
Most likely still operational when replaced with newer HD, digital gear.

Not bad for $150 on Ebay.  But I had to drive from Portland up to Seattle to pick it up (it wasn't worth shipping because it is so heavy).  The traffic in Seattle is TERRIBLE! Bumper-to-bumper practically in EVERY direction! It took me 11 hours round trip from Hillsboro to Kenmore and back again.  I must admit the gadget probably wasn't worth 11 hours of driving through heavy traffic.   :-\

The panel I bought is just the user-interface control-surface.  The original Grass Valley switcher with that control panel probably cost well over US$100K  That Grass Valley Zodiac is a "3-bus" or "3 M/E" switcher.

For comparison, this is the control panel currently sold by Blackmagic Design (an Australian company famous in video production circles).  It controls their top-of-the-line "2M/E" switcher. 

(http://www.fullcompass.com/common/products/original/107175.jpg)

Just the control panel (without the actual video switcher) sells for US$15K

The original Grass Valley analog switcher unit probably took 10 or more rack-units for the actual electronics that do the video effects and switching. 

(http://www.mccom.tv/image/cache/data/Equipment/Grass%20Valley/Grass%20Valley%20Zodiak%20Switcher%20pic%202-640x480.JPG)

But using custom chips and modern technology, the modern BlackMagic 2M/E switcher fits into 4RU and includes audio mixing and camera control features in the firmware.  And sells for US$3800!  This is very disorienting to old-school video people.  ;)

I bought a control panel for a larger television video switcher (Grass Valley "Zodiac")

That looks very similar to the one that runs the death star in the original Star Wars: http://www.partsofsw.com/dscntrl.htm (http://www.partsofsw.com/dscntrl.htm)

Got a Hakko 937 from a guy on craigslist for $50, although it didn't come with the key card so I made one out of an old membership card.   Works great and it's easy and fast to change the temperature.

I got it because my Hakko FX-888D annoys the crap out of me.  It works great, but I can't ever manage to change the temperature without getting out the manual.  It's a real pain.

Why don't you just write using a velt pen? Once upon a time I started to put labels on SMD bins. I quickly realised that was not a very smart move because it took a lot of time & effort to create a label and writing is so much quicker.

Try writing on black ESD reels. White (TiO2 based) inks do not usually come with fine tips and strong adhesion. Darker pens won't make readable result.

I find the Gold or silver metallic Sharpies do a good job on black but only because I can't justify a label printer like that  ;D

I bought a Samsung SSD a few days ago. I checked tracking yesterday morning and saw that DHL had handed it off to USPS with an estimated delivery of today (Friday). I checked tracking again today and saw this:

Code: [Select]
Your item was returned to the sender on
August 12, 2016 at 10:46 am in City 2 (30 miles away)
because the addressee moved and left no forwarding address.

Date & Time      August 12, 2016 , 10:46 am
Status of Item   Moved, Left no Address
Location         City 2 (30 miles away)

Date & Time      August 12, 2016 , 4:29 am
Status of Item   Arrived at Post Office

Date & Time      August 12, 2016 , 3:14 am
Status of Item   Accepted at USPS Destination Facility
Location         City 1 (where I live)

Not sure what to make of that. Apparently it arrived at the local post office, but then was returned to sender from another post office 30 miles away a short while later. And I have not moved in the last 10 years.

edit:

It's now Saturday morning and magically, my package is "Out for Delivery".

Well, you are lucky with that AUD $1000 limit, we have only EUR22 here, and you'll need to clear customs in 99% of the cases regardless how small value was declared unless it was sent by post. $90  processing fee is completely nuts though, leaving it to courier company should be cheaper I guess.

I received a BK 1856D that I ordered from eBay ($175) a couple of days ago (seller was nice to ship quickly and priority instead of economy).

(http://home.earthlink.net/~alank2/bk1856d.jpg)

So far I am really pleased with it.  I calibrated its internal TCXO to my rubidium reference (RFTG) without any trouble.

It has the option of using the internal clock or an external one, and if you enable the external one, it will display 1 more digit.  I wish they had just displayed all digits even when the internal one is selected even if it bounces around though.  I may try to find out where it "tells" the microcontroller (Atmel AT89C52) which one is enabled and find a way to override it.  It does take a full 30 minutes for the internal TCXO to warm up just like the manual says.

The display shown in the picture is it using the Rb clock as an external clock and me feeding what my SDG2082X "calls" a 10 MHz signal into it.  It is rock solid and does not bounce around, the SDG2082X starts up cold around 0.1 ppm off and then warms up to 0.16-0.17 ppm off.  I am pretty impressed with the Siglent generator, it is one of my favorite toys.

I also tested a 26 MHz Pletronics OCXO I got off eBay and it bounces around much more than the SDG2082X in the final couple of digits.  Maybe it would do better if it was actually soldered into a pcb instead of just the old breadboard it is in.

Alan, glad to hear you're liking your 1856D. They don't show up often on eBay. I have one in my repair queue that, at first glance, appears to have an issue with its power supply. Good to know the TCXO is friendly to adjust.

The power supply doesn't have a whole lot to it, hopefully you will be able to fix it easily.

I thought I found the way to enable the extra digit - seems to be controlled by the CN6 connector on the main board.  It is shorted for "external" and open for "internal".  I tested the input/output clock jack to make sure it didn't act differently to see if the microcontroller would switch it somehow and the input/output looks the same on it whether CN6 is open or shorted.  I thought shorting it would enable the extra digit, but I'm not so sure it does.  The last digit seems to come up "0" a bunch, more than you would think it should.  Not always though, when I feed a signal from my AWG, I can alter it and have the last digit be non zero, but using its internal clock and monitoring my 10 MHz reference signal, it went from 60, to 70, to 80, for those last two digits and I wouldn't have expected that.  You would think if both the internal and external clocks are 10 MHz that it wouldn't matter but perhaps it does more than just turn on / turn off an extra digit...
Title: Re: What did you buy today? Post your latest purchase!
Post by: alank2 on August 13, 2016, 12:45:54 am
Well, maybe it works fine, the difference with the 60-70-80 seems to be when it is below 10 MHz, even with the external clock.  Perhaps the "CN6 short mod" is the way to enable an extra digit.  It doesn't bounce around even on the internal clock....

edit : it seems that whatever algorithm they use loses a digit when the first digits are 99999, other than that you do get an extra digit by shorting the 2 pins in the CN6.

edit2: I guess it really isn't losing anything.  In 10s mode, log10(10000000*10) is 8 digits and that is the best it can do.  log10(9999999*10) is 7.99999 digits.

The thing that triggered me is last Friday when I was preparing an important report PPT for TI, LO crashed several time, and that makes me to save multiple times per minute, fearing I will lose more data.
What's worse is, all LO instances share the same process, so if one crashes, all other instances crash at the same time. I believe implementing SLSJ or SEH won't be hard, but they simply does not want to do so.
Some commercial tools, on the other hand, have moderate data loss protection. For instance, Altium Designer will catch SEH violations (aka. SIGSEGV in POSIX), then pop up a window, and allow you to continue working.
I feel very happy and privileged that all my employers didn't mind me being a bit of computing greybeard and using LaTeX beamer package to make presentations.

Altium Designer is a Ferrari of design suites when it comes to data loss protection. AutoCAD will gladly leak all memory then just crash, or sometimes will generate a design file that results with crashing the program when trying to open. Solutions on Autodesk knowledge base are just ridiculous - "reinstall video driver", "reinstall .NET framework", "create new Windows user account", "use Autodesk Crash Dialog on Close Hotfix" and so on.

It is a tough challenge and this book clears up a lot of mystery for me. It also has me scouring eBay for more test equipment. The book was cheap. The resulting equipment purchases are not so cheap.

Picked up a 10G ohm 10kV voltage divider. It was bit of a gamble as Unilab is an educational equipment brand but opening it up revealed some decent quality Welwyn 2% resistors. I bought it because of the difficulty of finding 9G, 900M etc resistors.

Initial testing indicates that the ratios are actually pretty good and I will only be using it where I want to measure higher voltages with higher than 10M loading. The 1kV and 10kV terminals have additional insulation. The cable was connected across the 1M resistor but I've removed it and will either fit a more convenient one or just use the terminals.

Quiz: How many errors can you find in the front panel text?  ;D

10gohm is too much for "only" 10kv, I have bleeders used in the >100kv range at around 500Mohm... a problem with that impedance is that bandwidth gets reduced to a few Hzs and bandwidth here means that at higher freqencies the output gets higher not lower...

Anyway good buy for the strange resistors

I've gotten a few goodies recently,

A few textbooks I have bought are Fluke's Calibration : Philosophy in practice. The hardcover is in pretty average condition, but all the pages look to be really good.

Another textbook is Resistor Theory and Technology by Felix Zandman (Founder of Vishay)

I also purchased a nice looking set of Dana current shunts. They are a similar concept to the Agilent 34330A, but there are 6 of them in a wooden case. The resistances range from 0.1R through to 10K000

I will post some photos when they arrive, I cannot find much info on them other that this from the 1984/1985 instrument catalog

Sold my MSOX3104A, then bought an MSOX6004A. Net difference: $3.5k. Picked up in person. Driving 20+ hrs on I95 is not fun. And for the first time I know there are non-free interstates.

That sounds nuts, but a great way to spend $3.5k. I love my MSOX6004A! So easy to use, I don't even think about it. Well done.

Hello!

Finally I get my 53131a...
I wait for a Gerry OCXO and a Poland Prescaler...  :clap:

It works very well... Only.. the display is dim... 
I must test the DC-DC converter for 5.2V in filament and 43V for HI VOLTAGE.. Next week I will try it...
If not I cannot have the VFD... What a shame!!  :-//

The first obvious thing I see is Trace rotation needs adjusting. Simple enough, get yourself the Service manual and have a read.
As for Calibration, the first sanity check is using the Probe Cal terminal to check if the square wave it generates is ~1 KHz. They are rarely exactly 1 KHz but plenty close enough for a quick check. Best advice would be leave the scope alone unless you have good reason to doubt its accuracy. Think less of scopes as an ultimate measuring tool but more so of a way of displaying waveforms.

Nice scope!
I guess you know you don't have to wait till your probes arrive? For low frequency, audio, etc, you can just use any old wires, with whatever kind of BNC adapter you can find. Any bit of coax with a BNC on one end, any impedance, spliced at the other end to alligator clips. Even plain wires. In the audio to few hundred KHz range, short cable impedance effects can be ignored.
With unshielded wires you'll get a few (tens to hundreds) millivolts of mains hum pickup, but it's all part of the learning experience. Have fun!

Oh, and btw. That scope, like most, has a calibration output. It's the little clip point in the bottom-center of the controls area. You can just wire it directly to the channel BNC inputs for amplitude and sweep calibration, since it is a low fundamental frequency square wave. It's also used for probe edge compensation adjustment, once you get them.

To the best of my knowledge such counters were used to measure how long a system has been active (say a machine with a limited life time). There is no way to reset them I think. Another mechanism for this was this mercury based gadget:

It's been a few weeks past already, but I bought a Hakko FX-888D station plus a bunch of tips, all from TEquipment while in a trip to US. It cost about 40-50% of what it would have costed here in Brazil, even with the dollar being so strong against the Real (our currency, it's about 1:3.5 at the moment) - about 100 USD.

Oh boy, I know it's an "entry level" station but I'm in love with it. My trusty but crappy Toyo TS-900 (local brand, attached picture) served me well and is now enjoying a happy retirement.

Coming from a single 24" NEC, this should be a huge improvement.


No bezels in your view vs. a multiple monitor configuration is appealing to me.  8) It should improve productivity with ~ the size of 4 sheets of paper side-by-side (less switching between applications), and I'm hoping it will make viewing schematics easier as well.

They're expensive new (~$800), but the unit I have is a factory refurbished unit I got shipped for $463 (30 day no-hassle return policy & free return shipping + 1yr. manufacturer warranty). Just too nice a deal to pass up IMHO, as the risk seems low with the free return shipping.  >:D

Not cursing you, but most of the time, RMAed units are either with excessive dead pixels or with huge amount of IPS glow/backlight bleeding.
Perfect panels don't usually end up being returned.
Sadly, you're quite right in most cases.  :-\

But as it happens, these monitors have had issues with the user input 4-way pad + center button, and I suspect this is the more likely reason it was returned rather than the panel from what I've read of all of the Amazon & Newegg reviews (most common defect from what I read). This is ultimately what I'm gambling on. I need to test it of course, and I'll have to wait until Saturday to find out for sure as that's when my DP cable will show up (I guess I could use the HDMI->DP cable or HDMI cables I have, but they won't run at the full 60Hz refresh rate). Call me picky, but I've more than enough time to test it properly IMHO (shouldn't take long to figure it out IME). For disclosure, my NEC wasn't a NIB unit either, and it's been great (had it for 7 years). Perhaps mine was an exception.  :-//

The free return shipping is what ultimately caused me to give it a go, so worst case, I'll have to return it and either accept a replacement or wait for a refund to post to my CC account.  :box:

FWIW, I went to open the back and fish out the loose screw, but there's nary a screw to remove to get the rear cover off. Seems the back cover uses tabs & notches to hold it in place.  :-- Which makes me nervous, as it can't have any visible damage should I need to return it. I'll still give it a go I guess, but will have to be exceptionally cautious.

Heh. Maybe the screw is their 'anti-return' trap?  Either to make people open it, or to 'prove' they did open it even if they didn't.
Anyway, don't go prying at the edge join. That's not the way to do it, and WILL break off retaining tabs and leave marks.
There are some videos around of how to open LCD screen cases. Basically it boils down to getting your fingernails under the edge of the bezel where it meets the screen face, and twisting up and out. Once the edges are released, the corners become easier (not easy, just possible.)

Appreciate the tip.  :-+

There's a couple of slots on the bottom of the rear panel, which looks like it's an entry/access point. Figure it's similar to IR remote controls (fine tabs that run along the perimeter). FWIW I've found it best to use something thin to tuck in-between the plastic shells so they don't snap back together as it's pryed, and work my way around (i.e. using a nylon spudger + plastic strips cut from a margarine lid). I've some other tools that are very thin steel as well, should that become necessary (would rather not, as they'll definitely leave marks on the rear shell & bezel).

But I will certainly check out YouTube and Google it before proceeding (might get lucky and this model is one that's covered).  ;)

Just got my eBay $124 LeCroy 9370M that was listed for parts.

Pretty dirty, fixed the floppy disk belt, changed the backup CMOS battery.
The two missing knobs are just the shaft that is broken. The encoders work just fine. That should be an easy repair, even if the knobs don't quite match the rest it will be functional.
It has most of the options, but I hear that, apparently, LeCroy has released a way to program the PAL for the rest but I have not found it yet.

Anyone knowledgeable about these: suggestions are welcome :-+

This bad boy... Wavetek 145. 20MHz function/Pulse generator.

All analog. None of this DDS rubbish... No stair stepping no R2R crossovers...  >:D

(Also no accuracy, no stability )

Had a bad cap or two. I replaced about 14 electrolytics. Had a bad transistor, and a cold solder joint too. All fixed.

I picked up a HP 3478A from EBay for less than $90 with shipping. We have a fancy calibration machine at work (university) used for calibrating all the test equipment so I'll be able to check the calibration (though it had a 2003 calibration stick on it that does not mean someone has not screwed it up.)

Swap the battery first to make sure the good cal. lasts a few years longer.

Last weeks I've been on a scope buying spree, wanted 2 scopes but ended with 4, must say that I didn't spend much in all of them  :D

-Fluke 123. new, out of the box with all accesories, owner had it stored for many years
-HP 1740A. nice scope in nearly mint condition, a proper scope not like the Tek rubbish  >:D
-Hameg HM303-6. Bought for 10€ with a channel broken and the timebase gone bad. All fixed now
-HP 182C mainframe with 2 100Mhz channels. Pretty beat up, needs an in depth restoration, I suspect all electrolytic cap are goners. The screen is bigger than most modern scopes  ^-^, I like it because is rare

Well they do tend to last 15+ years, so I suppose you could excuse the lack of battery holder. The swap isn't that difficult anyway, just be careful that your iron isn't grounded and don't short anything in the process.

As Vgkid said this is a Fein tool, German made (www.fein.com (http://www.fein.com)). Not many tools can be found here in Canada made in the US, let alone in Germany. The tool is of incredible quality. It is an oscillating tool but you barely feel vibration. It also has soft start so it goes silky smooth as you turn it on. And it has power that is right, does not slow down as you cut into material. I would not say i use it often, but when you need to reach tight spots or make plunge cuts , it is incredibly useful.

Yes the Hilti set is very nice, love it. This is a 12V tools but very efficient energy-wise. Used the drill to mix mortar, make holes in ceramic tile with diamond saws, drive drywall screws, drill holes. Used the impact driver to fix squeeky floor and drove about a hundred 3" screws into the floor joists, and the battery still showed 25% charge left.

Yes... Out of the bunch the Milwaukee angle grinder perhaps is the most powerful tool that needs to be used with caution. If you lose control it can make a lot of damage. With the Makita diamond disk it cut ceramic tile like butter, and that was what i needed  :)

Keysight U1282A DMM - now do I sell my U1273A or not?
I was pleased to find the U1282A does have a full setup mode with quite a few options. Not sure it was documented when Dave did his tear down. Mine included rev 1 of the manual which makes no mention of it, of course the manual didn't cover dual measurements either. So I checked the Keysight website and they have a much improved updated version, there was also new firmware which was easy to install.
She is a big beast but the huge display is nice. With 800 hours of battery life I changed the auto power off from 15 minutes to 60 and disabled the auto off backlight - if I want the sucker on, I want the sucker on!

I've had no problems updating firmware in a Agilent/Keysight meter but I have read the ugly stories from those who have. I updated the firmware in my U1273A with a home brew IR interface I held up to the meter during the update. The U1282A includes the IR interface so it was even easier. I did use a Win7 machine which may have helped. Mine came with version 1.00 firmware(website says 1.02 was initial, lol) so updating was likely a good idea. I say go for it.

They're surely some of the cheapest drives you can get, but they'll be mirrored and I've had good luck with WD in the past (once they get past the first day or so).
Title: Re: What did you buy today? Post your latest purchase!
Post by: SeanB on September 11, 2016, 07:52:29 pm
First thing on new drives run a full SMART surface scan, and if any reallocated sectors show up, or there are any pending ones, then suspect it. Will take hours, but the nice thing is you can do it using a USB2 drive caddy, as all you are transferring is control data. then install in the machine, format to what you want ( preferably a full format, so if there is any infant mortality it will occur on a blank drive) then scan again and see if the reallocated sector is grown or pending is higher. If so it is an infant mortality drive, so time to RMA it for failing SMART.

Good drives should go their entire lives with no reallocation, or only a few. If you are in the tens on a new drive it is not healthy. I had a few WD and Seagate drives that were DOA or which died during the scan. Much easier to change when it is only formatted and mostly blank and has a bad day.

Both passed the Smartctl full test with no problems. One drive is in the machine now having badblocks run on it. It's been running over 20 hrs now and is into the third pass. That's what's on screen in the background. Everything is looking good so far.

I bought these Wiha cutters as new at a Hornbach store. Not a second hand shop. They are now at my grandmother's apartment. It is strange that these pliers are not listed on the manufacturer's website. http://www.wiha.com/en/produkte/pliers/diagonal-cutters.html (http://www.wiha.com/en/produkte/pliers/diagonal-cutters.html)
Do you think they are good and genuine? They seem to be hard and solid. I think that these pliers might have been stored for four years or so. Now they are probably discontinued.
Searching "wiha z 12 0 25 180" gives no results. Strange. But i think that they are OK.
EDIT: The pliers look very nice and new, but they were not packed anyway. No plastic blister or something.

Bought an AVOmeter 8 off ebay. With 5 minutes to go it only had one bid and stood at £10. So I put a little bid on it for a lark. Turned out the original bidder didn't want to go any higher.

I think that these pliers might have been stored for four years or so. Now they are probably discontinued.
I believe it is possible. I remember these pliers at Hornbach 6 years ago. I have them too and no problem whether it is genuine or not.

I bought these Wiha cutters as new at a Hornbach store. Not a second hand shop. They are now at my grandmother's apartment. It is strange that these pliers are not listed on the manufacturer's website. http://www.wiha.com/en/produkte/pliers/diagonal-cutters.html (http://www.wiha.com/en/produkte/pliers/diagonal-cutters.html)
Do you think they are good and genuine? They seem to be hard and solid. I think that these pliers might have been stored for four years or so. Now they are probably discontinued.
Searching "wiha z 12 0 25 180" gives no results. Strange. But i think that they are OK.

If you got them as a "one of" out of a bargain bin, then they may have originally come from one of the Wiha sets. They sometimes include tools that aren't sold seperately.

Because those devices display the measurements. One could say they have the sensors built in, accessible via probes.
No they don't display anything.  :)

Sorry, I only looked at the top of http://www.tek.com/tektronix-and-keithley-digital-multimeter/keithley-dmm7500-series-7%C2%BD-digit-graphical-sampling-multim (http://www.tek.com/tektronix-and-keithley-digital-multimeter/keithley-dmm7500-series-7%C2%BD-digit-graphical-sampling-multim) which has a photo of one meter in the series that happens to have a display.

Good old meters.
Just be aware if wishing to use the 2.5 or 3 kV ranges these meters have only use original leads for safety's sake.
I don't know of any other DMM leads that might be considered safe at those voltages. One Avo I got had some pirate leads that looked the same as AVO but the didn't have AVO markings on them and I wouldn't be brave enough to use them at elevated voltages.

I had bad luck with FreeNAS and didn't find it all that intuitive - Not sure if it was a limitation or user error but I also struggled to create a shared folder from a single drive - it kept wanting to add the single disk to the RAID array.

OMV is really good however.  :-+ :-+

I'm afraid it looks like user error Steve.
If you had an array already then you would have had to create a NEW volume using the single disk.
You can also use a single disk if you set it up as an ISCSI target/extent.
The you would see the entire disk in windows etc.
I agree that Freenas is NOT very intuitive.
It is awesome though.

The Avometer 8 mk2 arrived today in a pretty banged-up looking box. Though, one nicely stuffed with peanuts. The carry case is not in the best condition.There obviously has been some heavy stuff stacked on it and it smells of old garage. The probes area bit bent but they seem original.

I haven't taken it out and tried it yet.

Edit: Had a quick look inside the battery compartment and found the batteries have badly leaked. Urk.

I have five multimeters, including a Fluke 87-III, but all I had were cheap probes. I bought the Fluke used and it came with Radio Shack probes.

I few months ago I decided I should get some real Fluke probes. When they arrived, I replaced the probes in the 87-III, then went to put the old ones in my probe storage box. When I opened the box I saw in there a brand new, unopened package of Fluke TL75 probes. Apparently I already had the idea to buy some Fluke probes sometime before.  :palm:

I have no idea why I stored them instead of putting them to use. Well, at least now I have a back up set.

HP 5340A Frequency counter 10Hz-18GHz - there are two revs, this is the early one with Nixie tubes. It is very clean inside and out - and seems to work perfect to boot. HP really gilded the lily on this one, even the power supply board is gold plated. $81.00 plus shipping - I jumped on it. This one was made in 1977. I believe the 1986 price was $8600.00 USD.

Sure appears to work. I can only test the input to 8.4 GHz, at this frequency it counts just fine @ -35 dBm which is in spec. The seller had it listed for $85.00 buy it now and I was thinking of buying it when it sold. Then a few days the same seller relisted it but for $81.00 - this time I jumped on it right away. There isn't even any dust inside.

I guess it's good that I took that model number out of my 'followed searches' list, or I'd have tried to grab it.  Congrats on a good  score!

I don't have the manual handy right now, but I think that if it's counting at 8 GHz, it's likely good to go.

Could not resist  ::) . The condition is good and inside it looks untouched (except that somebody did remove the old battery at some point). I have two options - either restore it as is or install a modern circuitry to make it more useful (and perhaps expand the ranges down to 1uV FS).

You need to work on your nixie-fu!   :P  (and start looking for one for your collection!  >:D )

It was introduced in about 1972, at which point its list price was $5300.  In '77 it listed for $6300.  I'm not sure when they switched to 7 segment LEDs, probably not too long after his was built.  I have to wonder - in another 20-30 years, will people be searching for equipment with 7 segment LEDs the way our little group of nut cases seek out nixie gear?

And I just looked further into the HP catalogs - the first showing the 5340A with LEDs is '83; in 1982 it still shows and specs the nixies.  IIRC I think '82 was the last year for the 5245L, too.

Well, not long ago I got a Keithley 196 with big LED digits. I must say I quite like it. It doesn't have the glow of Panaplex, but it'll probably last a lot longer. So, perhaps when Nixie and Panaplex become too hard or troublesome to acquire, maybe there will be a "Post your LED equipment" thread.

I got a Honeywell 620B for about $30 on my last CA trip; it has big honkin' 7 segment LED digits too.  I don't have any readily available pics of it (took some, but haven't uploaded them) and it's still out there, but it's a cool old piece of hardware.  I also have a soft spot (in my skull, I'm beginning to think) for the early HP 'dot' LED displays like those in the early 3490A DMMs, and have a few instruments with them as well.

Not a purchase, but still an acquisition. Coming soon to a repair thread near you, a  G & E Bradley  CT471C multimeter. Nothing much by the standards of today of course, but it does have the distinction of coming with probes to allow AC measurements up to 1GHz. Sadly the meter is stuck, and it probably has other issues besides.

Totally agree, just compare an old multimeter probe with that of a fluke 123 scope, they probably cant figure how to embed the connectors deeper and deeper and put more plastic around them

I have three sets of probes lying around here that make that quite obvious. Well, four really. A set of old AVO ones with blades for the screw-on terminals, a set with banana plugs, a set with the plastic around the connector and another set that looks almost exactly the same but if you look at the connector you see that is has a plastic tip on the end of the connector.

New in package HP 11536A probe T for 15 bucks + shipping.
My 1152A active probes plug right in. Should be fun for comparing probes and such.

TDS744A, what a nice scope. It has however some attenuating ranges in CH1 (200mV to 1V) that don't work.
After I repair it and become acquainted with it maybe i'll upgrade it to 1ghz

Maybe you want to see how it looks in real life. I like the design in general. The text LCD is very useful. I do not need to remember some abbreviations, that are also too small! Please see the comparison between Sigma and Cateye.

FAQ:
Sigma sport 3000 will stay on my old bike and the mounting stuff is a bit damaged, but the unit itself works like it was new and it is built like a tank! Really impressive. I think it was manufactured in 1996.
Cateye Velo 8 has that crap abbreviations that I do not want to remember. I got it without the bike mounting stuff and sensor and these are as expensive as a new Sigma BC 8.12.

I've one of these on my bike. Be careful of the wire connections to the bottom of the "docking station". They're pretty badly soldered, open joints with no strain relief. If you catch anything in the cable they immediately break.

By docking station you mean the bike mounting stuff?
Yes, i think that Cateye might be more durable than Sigma. It is possible. But I love the LCD on Sigma Bc 8.12.

Yes, with "docking station" I meant that plastic ring on the handlebars that the display twists into. The wires going out from it are not exactly what you would call robust. I also chose the Sigma because of the BCD (Big Clear Display :) ).

I bought these Wiha cutters as new at a Hornbach store. Not a second hand shop. They are now at my grandmother's apartment. It is strange that these pliers are not listed on the manufacturer's website. http://www.wiha.com/en/produkte/pliers/diagonal-cutters.html (http://www.wiha.com/en/produkte/pliers/diagonal-cutters.html)
Do you think they are good and genuine? They seem to be hard and solid. I think that these pliers might have been stored for four years or so. Now they are probably discontinued.
Searching "wiha z 12 0 25 180" gives no results. Strange. But i think that they are OK.
EDIT: The pliers look very nice and new, but they were not packed anyway. No plastic blister or something.

I think that my pliers are very similar to Z 12 0 05 180

I got these. Mine broke on the second usage. A peach of metal splinter of the blade at the very tip. Send them back, got my money back and bought from another company. No idea if mine were just an outliner, I'm pretty satisfied with my other Wiha tool. For diagonal cutters I can recommend Knipex.

An Alphasmart Dana. Surprised me by having the original branded wallwart with it. The NiMH battery pack is dead and the contacts for it are badly corroded. So I'll probably mod it to take rechargeables in the battery compartment for alkalines.

A D-104 microphone $10.00
A Diglint Analog Discovery with parts pack, unopened I might add... $50.00 (the cute little USB scope, logic analyzer, and function generator is well worth that.
Last but not least a really clean looking HP-3312A Function Generator for $150.00

Bought the one last week, and used it today to finish off 1200 holes to clean them up and fix damage from use. Probably took a whole 1g of metal and gunk out in doing so.

The other I bought at the flea market for R30, just because it was so cheap and looks so nice. Yes it is cast brass, not pot metal, probably from around the 1940's, as I also bought 2 1947 commonwealth medallions as well with it.

I was not too happy with the articulated crocodile clamps in the Elenco lamp, so I was placing the board on the mat with some scotch tape to hold it.   I saw this one and decided to give it a try.  The first impression is good.    It is heavy, made out of 1/8" steel, with some rubber feet, it will not move around.   It has a black finish a bit shiny.   If it gets to bother me I will cover it with black electrician's tape or spray it with flat black paint.

A light sanding would do as well. And FWIW, it also helps with proper paint prep, should you go ahead and spray with a matte black finish or matte clear coat.  ;)
So you have options (inexpensive ones I might add), should the OTB shininess be an issue for you.  :-+

Picked up an HP 6215A 0-1600V, 5mA variable supply a few weeks ago in CA.  I've been watching the wallet draining auction site for one for about a year now, but all were going for north of $100 plus shipping and I'm too cheap to pay that.  Found a nice one at a surplus store and got it for $40.   :-+

Nice! I just bought a 10kV power supply, Fluke 410B, although delivery will take long.

Need it to power properly 1.8V logic gates, arduino and zigbee stuff.

You could always use a 3rd party photo depository such as imgur, postimage, or photobucket and post them that way. You don't even have to create an account.

Drove 2 hours to Virginia to buy a Honda EU2000i generator. Indeed very quiet and fuel efficient. Just went to Autoparts to get some fuel stabilizer and some more gas.
Hurricanes Matthew had created more damage to our city than expected. I was thinking what a shitty place Florida is the day before yesterday, and it soon became my turn. Karma.

Edit: typo.

I'm in the Daytona Beach area.  Thankfully, Matthew passed just off shore at low tide.  Lots of tree damage, only a few shingles off the house.  Back in 2005, when we had the 3 hurricanes pass by, we got a Polaris P6100 6.5KW generator at we got reimbursed for through FEMA.  Not quiet, fairly fuel efficient-about 8 gallons for a 24 hour period, but big enough to run the house w/o AC, hot water heater and stove.  We only had to refill the generator once and it ran out of fuel right after the power came back on.  Talk about timing.

I got one that had been out in the yard at Apex Surplus about six months ago.  It was in the weather for quite some time - I'd seen it over the course of several visits, and finally this past spring visiting not long after it had rained I decided to rescue it and give it a home.   It needs some TLC, and is flat out missing one of the filter caps (annoys me, because it's far easier to restuff a can if the can is PRESENT, and whoever removed it buggered up the mounting wafer).  Mine is from the 'grey' period, and will need some scrubbing and waxing to pretty it up once it reaches the bench, but other than that is not too bad physically.  There are definitely caps inside that are toast, though, especially after baking in the California sun for lord only knows how long.

I've been looking for a paper manual for it, but so far the very few I've seen have been far more $$ than I'm inclined to spend.  There is, however, an excellent scan on both Keysight's site and the HP Archive, on the off chance you need one and haven't stumbled upon it.  The photos are actually greyscale and the scope images are visible, rather than being the harsh, pixillated black and white blobs that show nothing that are usually in scans available on the web.

Hi Pat
From the photo is doesn't look like it has been left outside, why on earth would you leave something like that outside for goodness sake? Someone has no soul.
When I opened mine up and did the daughter board push in, a couple appeared to be missing, but a quick look through the manual, it is an excellent scan, showed me this is usual.
it is a rather unusual device with the very low frequency and phase ability (all possible with GPIB I am sure) but nothing as convenient as a simple knob!

Rob, the surplus place I bought it from is Apex Electronics; they're a bit north of Los Angeles, CA, and for all practical purposes in the desert.  They have a fairly large building (that's pretty much filled to the gills), and an open yard that's about 3x the size of the building with all manner of stuff scattered about in it - scrap metal, parts, instrumentation, demilled 2" rocket launcher pods, a few partial light plane fuselages, lord only knows what else...  As someone who lives in the northeast in the US, where we get four seasons and have frequent precipitation, it's a bit surreal for me to go somewhere where things like this are outside in the weather, but they very rarely get rain where they are, and never see snow or sleet.  Often the gear is at least somewhat protected from rain by being under some sort of cover, but I believe that the precip is so infrequent and so light when it does come that it causes little harm.  In this case, the 203A had been more or less in the open, in a steadily dwindling pile of stuff that I'd looked at over several visits.  The day I finally bought it, I found it sitting on a table in the open and standing on its back, face up IIRC.  It had rained the night before, as there were some puddles on the ground.  My guess is that it had recently been upended and the rain came at such an angle that it rinsed the bottom cover off but not the top.  The front panel was pretty clean.

Now the DUST, on the other hand...  I don't recall that I've posted this pic before, but I got the 5232A on the same trip as the 203A.  It was on an outdoor shelf, up on top and just beneath a makeshift roof made of corrugated metal.  I've no idea how long it had been out there, but couldn't tell for certain that it was grey till I cleaned it off!

From a Bing maps aerial view (though the stuff in the yard looks like great piles of trash, there are actually some cool things to be found if you dig and poke):

The little sheltered area Dave went into at about the 11 minute mark (where he commented about the medical equipment) is where I found the dusty 5232A posted above.  It was on the top shelf, just below the 'roof'.  And if anyone's interested, the crystal ball was still there as of a few weeks ago (and must have recently been excavated, as that visit was the first time I'd ever seen it).

It is definitely a fascinating place to wander around in, and you truly never know what you'll find.  Shipping for the big, heavy old stuff I like gets $$$, though...

Probably more important: The 4mm Banana plugs make a reliable, strong and stiff connection to the unit, I assume?

Nice 'little' DVM there, Rob!   :-+ :-+  An interesting little tidbit I recall reading on some one of the HP sites about the development of that instrument is that initially they were having overheating problems with it, but didn't want to have to add a cooling fan.  Someone working on it got the bright idea to add a gap between the rear edge of the chassis shelf and the rear panel.  This combined with a similar gap at the front allowed the natural convection currents that now took place inside the enclosure to adequately cool things, and no fan was needed.  It's interesting to me to find out why some of the seemingly odd things you see in various devices came to pass.

Enjoy the additional glowing orange numerals in your shack!   ;D

Hey Gyro, sorry  :-[
Thanks, it is working great. Going to take it to work and check it against calibrated 6.5digit multimeter.
No problems, I had a max figure to go upto and the price I paid was below that.
Like you, I missed out a couple of times on other voltage sources.  The worst was a Time Electronics 2003 for around £40, boy did I kick myself on that one  :(

Picked up a very nice Fluke 6080A (1050 MHz) signal generator for $100 + shipping.   Advertised on eBay as powers-up, but remaining condition generally unknown.  The seller currently (10/15/2016) has six more (make an offer).  Besides being a bit dirty on the outside, all that was wrong electrically with mine was that the previous "repairman" shifted an IDC connector over a pin on the back panel, which created a bit of havoc.  These Fluke units are a close replica of the very well respected HP 8642 series, both in terms of specs and knobology, and could be a steal if you get one with an easy fix.  (Note:  I have no connection whatsoever to the eBay seller)

Following the review on TRX Bench I've just sent the IBAN payment for this and its companion tracking generator. The last decent test equipment I bought was for my 50th birthday and that was a L O N G time ago. The nice thing is that it goes down to 1Hz so I can use the same device for my audio work as well.

A couple of stainless steel cooking pots. Big ones.
One or other of these is intended to be the tub part of a vapor phase cleaning system, for vacuum gear. Bought two because I haven't decided on the size yet. There's quite a bit more involved, so it's the start of a slow project.
They are probably too big for a vapor phase soldering system, given how much that fluid costs.

It took me ages to find these. Finally thought to try Sydney's Flemington markets on Sunday. Success!
Stall #830  There are even bigger ones, too big for my purpose.
Total paid: $125 cash.
 20L   $60  (was $65)
 30L   $65  (was $75)
Next size up is 60L I think.


The manufacturer is http://www.oudunco.com/ (http://www.oudunco.com/)  (in China, no surprise.)

http://www.oudunco.com/oudun/viewPro.asp?id=54 (http://www.oudunco.com/oudun/viewPro.asp?id=54)   Those pots
 product name:     Earl Continental Barrel
 Product Number:     ODDY01-0102
 Product Specifications:     37CM
 Contact: anhuang0768@hotmail.com

No idea what the manufacturer's price is. But I figured that even if they're far cheaper to buy direct, arranging shipping on large, easily squashed things like these would be such a pain and expensive, that it was better to just live with the market seller's price.

They are seam TIG-welded, and the bottom seems to be thicker than the sides. Quite nicely done.
I think I can do the rest of the construction without altering or welding to the base pot at all. Fingers crossed.
The base heater will be outside the pot.

Vapor phase cleaning system.  Interesting!!  Do keep us appraised of your progress!  We had a vapor degreaser back 25 years ago when I worked at National Semiconductor - it was a sweet piece of equipment.  Wish I had access to one now.  (Of course it used a chlorofluorocarbon solvent, so I'm sure it would be an empty tank these days...)

Quite neat. Didn't test it thoroughly, but looks stable and accurate. It doesn't seem to overshoot during startup.

The fan doesn't start unless the load wattage is over 4 Watts or so.

I think part of the problem is that you get so used to holding the damned thing vertically that it becomes natural.  That's one of my pet peeves as well, but several times I've found myself starting to record video in portrait too.  I typically realize pretty quickly, think 'ahh crap!' and then get to stop and restart in the correct orientation.  I wish when they played back video recorded in portrait mode that they'd simply letterbox it rather than having the blurred sides that are normally shown.  I find those to be very distracting as the movement keeps drawing my attention away from the main video to try to make sense of what's happening in the blur, despite knowing that it's simply a blurred version of what I'm watching in the center.

If that was just a problem with iPhone users... I just lost my mind when I see videos on youtube filme with phone vertically. Just can't deal with it.
It's very hard for me to understand why people seems to forget how TVs and monitors in general are used. The only justification I have for those who film vertically is they're using one of these:

I've been a user of SLR cameras since 1986 or so, both film and digital, and I take still photos both ways.  The normal way to photograph individuals is in portrait (groups typically in landscape, but it varies).  It depends on what you are shooting.

Photos are one thing, We change the aspect ratio to fit the composition.
And YES it's not just iPhone users...
Thankfully many smart, and feature phone makers put the shutter button in the correct place for a right handed person to orientate the phone and take a video.

I bought an additional pair of International Instruments 1251 Dual Edgewise analog meters for my Kerbal Space Program controller build. i previously had 4 GE 180 single edgewise meters, and 3 of the 1251 meters. Due to a minor issue where a meter and a steel support bar won't cooperate in occupying the same space (pesky laws of physics...  ::) ), I discovered that I didn't have quite as much room as I had originally hoped. I ditched the 4 single meters for 2 double meters. That clears the extra space needed, and all around makes life simple for me. Bonus points, i got them for half the going average price on ebay, and they are the backlit models on top of that! I've had to mod all my other meters to be backlit (Dremel, polycarbonate, and a hot air rework station to heat and shape the poly to create a new translucent scale). Nice to not have to do that with these!

Replaced the incandescent bulbs with "aqua" blue-green LEDs to mimic the feel of EL illumination. I just formed the leads into a spiral that would screw into the lamp sockets to take the photo. Eventually, I'll have a small segment of proto board with the aqua LEDs, but also some dim red and yellow LEDs as well. I want to edge the color a little tiny bit closer to white, while also leaving just enough red and yellow wavelength light in the mix to let a red and a yellow bar on the scales light up correctly. The scales will be modeled after similar meters used in the Apollo spacecraft.

I do occasionally work on cars, having two driving age offspring at home, I've been looking for a replacement for my 1980s KMart set of sockets (believe it or not, they weren't too bad).

I was wondering which brand would last me the rest of my wrenching days and started having a look and read about the Bahco sets and bought one - the S106 here in Australia.

Thanks, roffvald.

Some tubing to repair an oscilloscope.
Enough 0.5mm 2B pencil leads to last a lifetime.
A bunch of wire bootlace ferrules. Some of the tray separators had come loose in the mail, so I had an opportunity to roleplay Maxwell's Demon for half an hour. (I really would rather not have.)

Oh, and for lunch today, bought this morning: a long French baguette, philadelphia cream cheese, Tasmanian Camembert, and a $10 section of real Danish salami. And then a goanna ate it. Ha ha, really. Went on day walk with friend, when we got to the place we sat for a while chatting, packs open to have snacks. Then we went for a walk in the vicinity, and though I put my food back in my pack, I didn't secure the pack well. When we got back, my gear was strewn around, everything ripped open. It ate ALL the cream cheese, most of the camembert, all but a little section of the baguette, and all of another half loaf of bread. Only took a chunk out of the Danish, which makes me doubt the goanna's culinary taste, since that salami is delicious. Though he left me enough for a meal, so that's something.

While waiting for my laundry to be done, I went to the electronic store nearby and bought some things: Isopropyl Alcohol for cleaning, Ice Spray, Lan/USB/BNC cables, some transistors/diodes, two divider networks for multimeters with a tolerance of 0.5%(9M, 900k, 90k, 9k, 1k), three 10mOhm 1% Shunts from Isabellenhütte and this board with a hv transformer in a can, where I don't know what it is for.

Around 8:00 am, I received my hobbyking parcel I waited a long time foir, because after I ordered the parts the Lipo battery suddenly wasn't available anymore. I got a akku doctor, a Accucel 6 80W charger, the temp sensor for it, it battery itself, some lipo bags and XT-60 connectors. All this so I con solder something when I'm not at home or when I'm going back to my "home town", aka birth town. The charger is smaller and lighter then my Ultramat 16 and therefor good for traveling.

Edit:
I also bought a W530 along with a 512GB SSD and a 1TB WD Red to put in the ultrabay HDD caddy. Just some things to start university :D

HP 8091A 1 GHz rate gen with 8092A delay gen and two 8093A output modules. I don't really need it but it was $40.00 plus shipping. Kind of fun to generate square waves to 1 GHz, rise/fall times are under 300 ps at all frequencies according to the specs. Without a much higher frequency scope I can't verify.
It was sold as-is and needed a little TLC. The power supply bulb was dead, replaced it with an LED. The power switch was sticky - cleaned it. The main rate adjust 10 turn pot was broken, replaced that. The Delay module still needs some TLC, it works to delay the signal properly but the divide by 2 option does not work. Everything else seems to be just fine. I was quite surprised to find it has no fan in it, I didn't know HP made anything back in the day without at least one fan :)

My DSOX3014A modded to 500 MHz does a nice job displaying a 100 MHz square.

From local surplus store and also sort of electronics parts recycler, all used though, scored a 10 Amps Corcom EMI filter, and 3 RF flange mount 50 ohm resistors, all for just about 3 bucks.   :P

Careful of those filters, there are RIFA capacitors inside there, and they also have the same failure mode as the transparent versions, plus the ferrite filters inside can cremate themselves and short out.

Are the shrouded sockets an extra option? I though these E36100 series supplies had the ordinary screw-down binding posts.

Looking lovely, by the way. :D

Yep, they're a no-cost option if you can tolerate the four to six week order time.

I much prefer them over the screw-on binding posts since I have tons of cables with shrouded banana plugs on both ends.

So what I do is I just leave a set of cables permanently attached to the power supplies, then if I need to plug them into a breadboard I can do so with ease. Or if I need to connect them to bare wires or directly into any component I have alligator clips which can plug into the shrouded banana plugs.

With this arrangement I can always have the cables ready and easy to access for most of what I do.

How did they pass CSA and RU (Recognized UL parts) certifications?

When new, electrically, those filters worked as specified, and passed testing just fine.. They fail after some time, sometimes years.. Components deteriorate, and then they fail.. But unlike some other that just don't filter that good any more, these guys go in a blaze of glory, explosions and such...  Hence the infamy...

I don't think new ones do that anymore, for some years, but old ones were lemons.. So on old used equipment, preventive replacement is recommended...

Another step towards making decent test leads, *without* all the ridiculous excess safety frills and too-small wire gauge of commercial ones. The really nice wire I found a while ago, described here: https://www.eevblog.com/forum/testgear/new-leads-recommendation/msg981058/#msg981058 (https://www.eevblog.com/forum/testgear/new-leads-recommendation/msg981058/#msg981058)

I had a small packet of old simple, small  4mm bare banana plugs, but no way to get more of the same. Hadn't been having any success finding a bulk source of nice small 4mm banana plugs, until recently these turned up:
  https://www.aliexpress.com/item/IMC-Hot-4mm-Inside-Dia-Male-Female-Banana-Plug-Bullet-Replacement-10-Pairs/32339136046.html (https://www.aliexpress.com/item/IMC-Hot-4mm-Inside-Dia-Male-Female-Banana-Plug-Bullet-Replacement-10-Pairs/32339136046.html)

I had actually only wanted the plugs, but they come in M-F pairs. Which does mean you can make banana extension leads.
These are nice! They make a very firm contact, definitely not going to pull out accidentally. Also they wet with solder easily. I don't know if that gold-colored plating it actually gold, but it seems OK. And they are cheap.

Now, for probe bodies and right angle male banana plug bodies, a bit more than heatshrink tubing is needed.
Hmm, if only I had a 3D printer....

Oh wait, I do. Or will, when it arrives. Ordered this one yesterday:

Yep, many types and sizes. https://hobbyking.com/en_us/catalogsearch/result/?q=connectors (https://hobbyking.com/en_us/catalogsearch/result/?q=connectors)
They even have that exact one: https://hobbyking.com/en_us/4mm-gold-connectors-10-pairs-20pc.html (https://hobbyking.com/en_us/4mm-gold-connectors-10-pairs-20pc.html)

However that's the only 4mm one that is long enough to be banana jack compatible. Also Hobbyking are more expensive, and will charge postage (which I can't get their site to estimate for me, for some reason.)
So I'm happy getting them from Aliexpress for 22c/pair, free shipping.

Speaking of inline connectors, those Solar MC4 Connectors are cheap, waterproof and rated to 1000V. Ordered some of them too.

Here we go. Still in the middle of setting everything up as I'm only just winding down from my relocation.

But I've managed to quickly get these up and running just to make sure they work.

Voltage readback is pretty accurate with no load attached.

I did test current briefly with a load and while it isn't quite as accurate it's still within claimed spec.

They're pretty quiet for most part so I'm really pleased about that (especially with the units powered on but with their outputs off).

Zhaoxin in China is a shitty brand that only cellphone fixing technicians will use. No one in R&D uses that shit. So does Atten, also a shitty fixing technician's favorite brand.
It's not about who can copy the design -- anyone can, but building a knock off $500 PSU in tens of copies won't make money as quick as $100 PSU in thousands.
Good Chinese PSU brands are Rigol and Itech (BK Precision's OEM, owned by BK).
Yes I know, I didn't want to say nothing bad about China (as there are reputable brands, as you said), I was just saying that it wouldn't be too expensive to build a knock-off PSU of this Agilent (from what I remember it uses their typical topology known for years) one and it would be nice "medium price range" device, without paying "HP tax". Like Hakko knockoffs can give you nice bang per buck;)

Beautiful power supply:) I had a small heart attack when you started poking the knob with your little finger just near the unscrewed positive terminal with device set on 250V (considering you had bridged V- with GND on both channels).

Yeah I know, but that one was less obvious:) As you noticed, it's actually not that easy to electrocute oneself with DC unless your floor is wet and you're wearing Australian tactical footwear like Dave, but it's better safe than sorry.
And we better not spread questionable practices amongst people - if someone wants to touch live wires as a career, one goes to sparky school and gets proper licence, then one will do it every day installing 230V terminals to households, combined with working on heights with questionable quality devices you use to climb an electrical mains pole:))

I made a trip to Orange County (just south of Los Angeles) a few weeks ago for the 50th anniversary reunion of my high-school class. Alas the traffic in the basin is so bad that there was no practical way of driving up to Sun Valley to visit Apex.  I may plan another trip and fly into Hollywood-Burbank airport which is much more convenient to Apex.

I tried visiting one of the last electronics surplus stores in Orange County, but it was gone and is now a sleazy shop for cheap auto electronics (and tires and wheels).  So apparently there are no more electronics surplus shops in Orange County.  :-[

I swear the traffic seems worse on the weekend than it is during the week!  It stinks about all the surplus houses closing down.  Apparently I started traveling out here a decade or so too late for all the prime stuff.  Coworkers talk of the glory that was the TRW swap meet in Lawndale; these days it seems to be more computers and consumer electronics than anything else...  Don't get me wrong, I still go if a visit is timed right, and have come away with some fantastic bargains, but can only imagine how much financial trouble I'd have gotten in to had I been there ten or fifteen years ago!

Mental note - call ahead next time.  And based on my (admittedly limited) observations, no, LA doesn't ever not have traffic.  At least apparently not between about six AM and midnight or so, and certainly not when places like Apex are open!  Cool area to visit, but I wouldn't care to live there - too crowded for my tastes.

I look forward to reading about your frequency counter repairs.

Magnification is 7-45x. It is the same like this http://www.amscope.com/stereo-microscopes/7x-45x-trinocular-stereo-zoom-microscope-with-dual-halogen-lights.html (http://www.amscope.com/stereo-microscopes/7x-45x-trinocular-stereo-zoom-microscope-with-dual-halogen-lights.html)
Mechanics is absolutely ok. I think it's the same manufacturer also for amscope :)
No I didn't fount that at Beijing Rd therefore my colleague in Shanghai order it for me from taobao.

I'd suggest you checking out Mr. Carlson's video where he repairs an oscilloscope. You might not get the answer you're looking for but it will DEFINITELY shed some light on the issue. His knowledge as well as his videos are out of this world.

Got this resistance decade box from ebay :
(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=272276)

Another bargin (I really drive hard bargins  ;D )
Not quite what I was expecting, larger than I thought.
Quick test with dmm shows ranges ok but a little poor in terms of accuracy, then I noticed it says 5% on the front.

Inside, looks like lots of 5 or 10 watt wire wound resistors.

Not sure why I would need resistance box which is capable of dissipating power but hey it works.
Yes, each range is fused.

I think this "60 watt" writing on front panel could be a clue;)

It's a very nice device if you deal with power electronics - amplifiers, power supplies and so on, and so on, or for example tube gear. In most cases you don't need 0.1% accuracy, just something to plug in and dial-a-resistance instead of exchanging random power resistors you have in your bin.

Of course if you buy these things to turn dials and watch numbers on multimeter, then it's useless. But if you need to substitute real non-critical accuracy (i.e. everything that isn't part of for example differential amp) resistors during testing, it's better than most small units that would fry when you put an amp or so through them.

As far as I can tell, a variable load is pretty much what it is, unless you're tinkering with some new high-power circuit design.

Newegg had it on ebay for $80 just as I was pulling wire and expanding my network. Inside the case I found a 10 pin header giving convenient access to an rs232 serial console. Also I rooted it just for fun. :-+ Today I plan to secure it then swap it in in place of two 8 port switches that are full. I wanted managed switch for vlans and this has more features than I need, but I'm enjoying learning what all those other features are for.

its 220V AC . so this is No plug n play unit.  its part of a project.
not recommended for professional use IMO, but ok for the weekender.
all I need now is just to lose 25 volts from the Australian AC mains wall outlet.
and see that she's all grounded in reality.  :-//


my plan is to use 1000w microwave oven transformer as a step down transformer. add ground tabs and input fuse.
I plan to use a old computer ups power supply case for a box.   taping 0v and 240v  as input & tapping 0v and 220v as the output.

It's normal to design gear for 10% tolerance (or even 15% in older devices), so 250V is still in spec for 230V +- 10% :)

But not for stuff designed ( like many modern components) for a 220VAC supply, and which are often further optimised ( because this means less of that expensive CCA or copper wire is needed) for 200VAC operation. This applies to anything with either a heater or an induction motor in it driven off the mains.

I was mainly thinking about "electronic" devices:) Anyway if a device is meant to be used at 220VAC (i.e. for local China market), designed for 200VAC (for cost saving) and badge-engineered for 230VAC (to sell it in Europe/Australia) then I'm not sure I'd want to use such product anywhere.

Other side of the voltage conundrum is too low voltage. Few months ago I had some power grid failure locally and for few hours instead of 230V-230V-230V three phase supply there was around 80V-0V-0V. It killed all relays in my exterior lights setup as of course there was not enough current going through relay coils. I also learned this way that 1) I could make an awesome techno party with all the strobes going on from LED lights, 2)my computer's PSU can run on 80V (I didn't run any heavy tasks on it of course and checked if cable wasn't getting too hot, no problems whatsoever) ;) Next day I installed incandescent bulb in the toilet, trying to "read a magazine" with flashing lights was life-changing experience.

Looking forward to hear from you about the print quality on your unit. I've been thinking about buying one printer out of Aliexpress but just like you've said, there are so many out there. Thanks for sharing your initial thoughts though.

May I ask where you managed to get so many ESP32s from?
Title: Re: What did you buy today? Post your latest purchase!
Post by: ChristopherN on November 30, 2016, 11:57:21 am
Sure, I ordered the modules directly from Espressif Systems.

They shipped really fast using DHL Express. I had some customs trouble, but that was DHL's fault.

May I also ask you for the price per module? I have a client who desperately wants me to get some work done with one of those...

Just ordered a Maynuo M9710 DC Load with USB adapter cable. The price and capabilities will cover the two projects I need it for, then I may look at modding/improving it as a mini project. If it's possible, I may even look at expanding it to a 300W vresion. More feedback when it arrives.

The part number indicates its not ESP32 but ESP8266EX. The price is $4 on aliexpress.

ESP-WROOM-32 is a thing too, but it has more pins.

I have a M9803, which I think is the predecessor to that one. I've had it over 10 years and it's been a decent and useful bench meter. It's nice to have something that can sit up out of the way on a shelf and run without batteries and not turn itself off. I use it more than my Fluke 87-III

When you consider where China is now, reading about what it was like for most of the 20th century will blow your mind. How anyone could have remained sane through that period is beyond belief.

Got a Data Precision 245 multimeter. Unfortunately someone drove a screw into the common socket and that's stuck there now and the batteries died, leaving their flaked remains all over. And I can't get the thing out of the case. Pulled it a quarter of the way out and then it is stuck. Does anyone know where I can get a manual without having to pay more for the document than for the meter itself (or how much it differs from the 248, for which a manual is available far more conveniently)?

I've no experience with that particular gun, but can safely say that if you manage to get hot glue on you, be aware that it is VERY hot, will stay that way for an unpleasantly long time on your skin, and will burn the hell out of you.  Probably worse than solder, because solder can at least be flicked off and will go away and stop burning you.  Molten glue is, well, glue, and can NOT be easily flicked off.  It sticks to you like its name implies, and takes its damned sweet time cooling off while you hop around waving whatever appendage you've gotten it on in an effort to make it go away (it won't) while yowling in pain.

Trust me on this.  I was gluing reinforcements into shipping boxes once many years ago, and managed to get a blob of glue where it wasn't supposed to be.  In an unbelievably moronic moment of dopeassity, without thinking I reached into the box and WIPED IT AWAY!   :palm: :palm: :palm: :palm:  |O  The result was an unpleasant experience (though it would doubtless have been hysterical to anyone who happened to be there to see it; fortunately as a mild salve to my ego in my case I was alone) that taught me a good bit of respect for the hot melt glue gun and that which spews forth from it.

All that being said, they are very useful devices as long as you don't glue yourself.

followed me home from the swap meet at the radio museum today.  It turned 61 early last month!  His highness there was on it and 'scoping' things out less than a minute after I brought it in and put it on the cart.  It seems to be lab cat approved, at least as a perching spot.  Once it's running (I haven't tried to power it up; was told that it was turned on once and nothing seemed to happen, then popped when turned on a second time...) it will doubtless be a desirable piece of feline real estate for winter lounging seeing as it has 67(!!) tubes on the chassis and 5 more in the plug in.  Space heater!!  It's now in my long evaluate-and-repair queue.

I'll start another thread with photos of it in the 'repair' or 'test equipment' section at some point in the next few days.

Hi Pat, Looks nice,   :-+    and the scope too.

Edit;  when you are firing it up, watch out for felines and the 20kV supply is just behind the rear panel at the back right hand side. My 545 had buggered "low voltage" (150-500V) filter caps - found by in circuit ESR testing - the going pop sounds a bit similar.

Keithley Low Level Measurements for 2€ shipped. I know I can download 7th edition for free, but paper is more feasible for reading in public transport.

HP3478A for 125€ shipped from Italy. I received it in metal case what impressed me. It was entertaining to make a deal with Metaf SRL because after few emails with them I realized they want to make much more bigger deals than antique multimeter for few euros. :-DD

Rob, thanks for the tip.  My initial suspicion was that perhaps one of the filter caps in the low voltage power supply had moved on to the big junk box in the sky. (And yeah, that one always makes me chuckle, too, considering that there are likely people who work with micro controllers and the like exclusively and think that 12-15V is 'high voltage'.)   :-DD

Those will be my initial suspect when I get to poking and prodding the old beast.  I need to revisit your thread, too.

Fisher Scientific Stereo Master SCL-40L.

I've long wanted a stereo microscope for inspection of soldering work and other things. After a much needed thorough cleaning, it works very well. I took a lot of residue off the lenses and everywhere else, probably deposits from flux smoke. It does not have a continuous zoom like the nicer new ones, but it switchable between 2x and 4x (objective) and has 10x eyepieces, so it's 20x/40x. I'd prefer 10x/20x I think, so maybe I'll need to invest in some eyepieces. The bit missing from the bottom isn't necessary for inspecting PCBs. I am making an LED light ring for it that will do a much better job than the not-so-bright incandescent bulb it has.

This was a bargain at $20 CDN (~$14 USD) at a local electronics recycler.

If the foot is heavy enough, you can mount it the other way around so that you can inspect the PCBs on the flat table surface. The eye-pieces on these microscopes are also a standard size, so you can usually buy generic replacements.

Add a .5x barlow lens to make it 10-20x. It also doubles the working distance making it easier to solder boards under the microscope.

Bought a new multimeter during the recent Black Friday weekend. It arrived today. The Fluke 87v.

I first wanted the 87v last year not long after I got my first DMM, the Extech EX410 (which was an upgrade from a RadioShack 19-range analog multimeter). I told myself that if I still wanted the 87v after a 30-day waiting period then I'd get it. Couldn't get myself to buy the 87v after 30 days because the EX410 did everything I needed a DMM to do.

After more than 300 days I found myself still wanting the 87v, so I got it. The Fluke 87v is overkill for my needs and for my electronics experience level.

I don't expect to buy another multimeter for a very long time.

I will be interested in how you drive them, I've got a few myself and fancy chucking them in a universal WiFi IN-12 CCCP Nixie display much like Dave's new project  ;)

Of course fast reaction is what is not going to be the best when using Wifi, Bluetooth, etc. But as an indicator it would be a shame to not use such tubes in the same HV box.

I told myself that if I still wanted the 87v after a 30-day waiting period then I'd get it. Couldn't get myself to buy the 87v after 30 days because the EX410 did everything I needed a DMM to do.

After more than 300 days I found myself still wanting the 87v, so I got it. The Fluke 87v is overkill for my needs and for my electronics experience level.

I don't expect to buy another multimeter for a very long time.

May I ask you, was it a good a good Black Friday deal?

Yes, it was a good deal to me. The 7% Black Friday discount + TEquipment member discount + no sales tax + free shipping got me the 87v for $345.90, and I got a free multimeter case too.

I later found the 87v being sold new from an eBay seller for $329.99. I felt more comfortable having bought from TEquipment.net, which is a Fluke Authorized dealer.

Now who are you kidding! HiHi

Now seriously, that s a nice meter. Good size, reliable, accurate, tough. Won't regret that.

You know, I saw the following multimeter on amazon yesterday and thought to myself "I have to get one."

Do you find the display being somewhat dark? Mine is uncomfortably dark for Bench use and trying to figure out i looked in some youtube videos and they seemed indeed dark. How's yours?

My 87v's display is darker than the display on my Extech EX410. I didn't notice it until I read your comment and then compared the 87v to the EX410.

Attached is a picture of the 87v and the EX410 side-by-side for you.

12x IN-9 Nixie Bargraphs (yes I know there's only 10 in the picture). I intend building an audio graphic equalizer with them.

McBryce.
I will be interested in how you drive them, I've got a few myself and fancy chucking them in a universal WiFi IN-12 CCCP Nixie display much like Dave's new project  ;)

Of course fast reaction is what is not going to be the best when using Wifi, Bluetooth, etc. But as an indicator it would be a shame to not use such tubes in the same HV box.

I intend to just use a simple row of passive filters being fed into Op-amps driving current sink transistors. Nothing fancy. They should be fast enough to keep up with an audio signal.

I finally got a DE-5000 LCR bridge. Bought on ebay for $141 including EMS shipping from Japan to Poland and then +23% vat on arrival (why all offers on that gear are from Japan? Don't know). Still cheaper than buying it locally which costs upwards of 250€ with accessories.

I love this meter :D

I looked at the cross-section of this solder under my new-to-me stereo microscope (which I posted about here a few days ago). The 5 distinct flux cores are clearly visible, which is rather interesting. Intrigued, I look at several other solders, and all have one single core of flux. There is one exception: A 2.5 oz roll of Radio Shack 60/40 Rosin Core solder, which also has 5 distinct cores ... it must be that the OEM was Loctite/Multicore. Interesting. Now, don't necessarily go running out to buy this solder thinking you'll get Multicore solder, as my roll is ~20 years old now.

I've got smoke absorber unit today for my homelab. A long overdue piece of gear. I don't solder that much at home, but still, it's cheaper to pay once for the absorber, than pay later to doctors...

It's rather simple, large 255 sq.m/hr metal box with 120W fan and three-stage filter sandwich and some rubber seal gaskets. It's made by local Taiwan brand, likely these guys : site (http://ushop10028.hiwinner.tw/ec99/ushop10028/GoodsDescr.asp?category_id=95&parent_id=0&prod_id=AIRCARE101A).

I added three 'new' boatanchors to my collection-o-crap, further ensuring that my house will not blow away in a strong wind.  (They do, however, likely make it MORE likely to simply collapse...)

A pair of old HPs and a GenRad followed me home from the museum today.

First, an HP 202A Low Frequency Function Generator; this one has a pre-1960 serial number:
(https://photos.smugmug.com/Other/Miscellaneous/i-dsBFsfN/0/L/IMG_4489-L.jpg)

(https://photos.smugmug.com/Other/Miscellaneous/i-4mVHTv3/0/S/IMG_4490-S.jpg)


Second, an HP 650A Test Oscillator; this has a 1962 serial number:
(https://photos.smugmug.com/Other/Miscellaneous/i-LfhRtMz/0/L/IMG_4491-L.jpg)

(https://photos.smugmug.com/Other/Miscellaneous/i-WJkqPDZ/0/S/IMG_4492-S.jpg)

And lastly, a GenRad 1001-A Standard Signal Generator.  This one I've no idea as to the vintage of as my experience with GR is very limited, but from reading I've done, based on the meter shape it's fifties era production:
(https://photos.smugmug.com/Other/Miscellaneous/i-BXNHSNR/0/L/IMG_4493-L.jpg)

(https://photos.smugmug.com/Other/Miscellaneous/i-z8PnTsq/0/S/IMG_4494-S.jpg)

The HPs are definitely in need of some serious TLC (the frequency adjustment of the 202A is binding and the amplitude adjustment pot on the 650A turns all the way around and makes scraping noises that pots in my experience should not make), but everything on the GR seems to turn very smoothly and switch as it should.  Lord only knows when I'll get to them, but they're now in the queue...

Finally, after waiting for years, scored for $40 a used variable autotransformer or variac or slide regulator (named by the manucfacturer)  :-//.

It says made in Japan, not sure about it's quality, so dirty that I had to tear it down.

Rob-

The 650A uses the lamp stabilization in the first four ranges (x10 thru x10k); x100k & x1M use a separate oscillator without a lamp. 

The 202A doesn't have a lamp; its signal source is a bistable multivibrator circuit, the output of which it then integrates to get a triangle wave which is further folded, spindled and mutilated to obtain a sine wave.  It's distortion is only rated to be <1% on all but the highest range, which is spec'd at <2%.  I think its 'claim to fame' is mainly that it goes as low as 0.008 Hz (125 sec/cycle).  Its maximum output frequency is only 1.2kHz.

These should be fascinating to play around with.

Thanks.  :)

Pricing is similar to Hakko here in the US with a single segmented hose (i.e. FJ430 using the EEVBlog discount at TEquipment = $640.39). Primary difference being that the current Hakko model uses a plastic housing rather than metal. Better to wait for an older HJ3100 IMHO.  >:D

I believe the one i bought is just a transformer and the 200W limit comes from the amount of heat the casing can dissipate. I am not 100% certain of this so any input or experiences people might have are welcomed.

It says on the embroidery machine that it is 110V's and i imported it from USA. I have feeling it would work just as well with 230V's but it being expensive piece of a kit i dont wanna risk it.

60 small plastic lenses. For Au$6.96 total.
Search ebay.com.au: LED Light 23mm Convex Lens PMMA.
Listings all say 23mm dia, but the lens is actually 21mm diameter, with a small projecting rim.

Some of these are for a microscope LED-lighting project. Which has been stalled for a while since the only cheap lenses I could find were all much larger, for 50W LEDs. These ones suit the small 10W LEDs, and allow packing 4 of them on small fan-cooled heatsinks.

20161214 edit to add 2nd pic - a few more bits and pieces recently, for a future larger 3D printer (sort of) project. Just building up stock for now.
Does anyone know of a Sydney seller of the 20 and 40mm square T-slot extrusions? I can buy from overseas, but only in quite short cut lengths. For general pottering, it's better to buy in original lengths; 4 to 7 meters. But so far no luck.

And more. 3rd pic. Some charge-protection-converter modules for 18650 batteries.
In the post. Now I wait.

TP4056 Charge And Discharge Protection Module
Input voltage: DC5V
Charge cutoff voltage: 4.2V ±1%
Charge maximum output current: 1.2A
5 for $3.49

FC-96 1A 5V Lin-ion Charger and Protection Module
Charging cut-off voltage:4.2V ±1%
Battery over-discharge protection voltage: 2.5V
5 for $3.39

DD1205 1-6V to 5V buck boost DC DC converter
Input voltage DC 1 ~ 6V, output DC 5V(+-6%)
Long time maximum output current: 1000mA
Working frequency 1MHZ. Efficiency 60%-85%
2 for $4.49

Not exactly a purchase, but more like an exchange.

I've gave my Weller WD1 + WSP80 iron, in exchange to this Data Precision 8200.

The picture is just a rapid turn-on, to check things up (i've used my most recent cal multmeter), 2 digits less than the calibrator.

My Maynuo M9710 arrived last night. While unpacking it I noticed it rattled... not a good sign. I opened it up and found they'd given me a "bonus screw" inside. I checked everywhere and the screw hasn't fallen out of any heatsink / transformer / casing etc. On close inspection under the microscope it doesn't look like the screw has ever been used, so I'll assume it's a spare.
The build quality is absolutely top notch and there's no sign of fake / dodgy parts inside. Passes all selftests and works fine. Strangely, it came in a double box like Rigol does, but the outer box was an iTech 8511 box?

I'll be giving it a full test over the Christmas break.

Nice trade. i always wondered how those newer Wellers are.
I've the same setup with an additional iron (WMP) and WDH20T stand (connects to the WD1 to fully utilize the setback features; works with both irons).

Performance on both irons is excellent IME (good thermal recovery). For example, I can solder at 500F without being on the joint too long (assuming I'm not soldering over a ground plane).

And as you're in the US, you should give the Hakko FX-951 serious consideration (it uses cartridge tips, but they're not expensive; ~$11 for common profiles/shapes). Simply put, it's an amazing value as well as an excellent performer. Another benefit is the thickness of the plating on Hakko's tips is such that tips will last for a decade with simple care (keep it clean & tinned).

Between the two, I'd go for the Hakko. Unfortunately, it wasn't out yet when I bought what I'm currently using.

Another brand to consider would be Ersa if you're after a really good station that doesn't use cartridge tips (their tips are also very well made).

FWIW, I mention the tip thickness as Weller has had some QC issues with the LT series & ET series tips that are made in Bosnia or Mexico respectively. A quick check of the good vs. bad tips I've gotten, it's ~33% (i.e. the plating sloughs off or is cracked).  :wtf: Their tips made in the US, Germany, or Japan don't have these issues.

Bought one of these today...

Got an extra 0.4mm bent tip and negotiated a further $50 off and free shipping ;D.

These are terrific irons. They are an order of magnitude better than classic Hakkos, Wellers etc and the tips last a long, long time. We got one for work and "I was so impressed, I bought the company". No, rather I bought an iron for myself. Quality is remembered long after the price is forgotten.

These irons have a USB port for software updates etc. If the iron had Wifi, it could be advertised as the world's first true Wifi hotspot.

I've been using WD1 + WMP for almost a decade. I've changed more tips because needing different shapes than wear out.
Recently I've bought a second hand WR 3M, with hot air and a dessoldering irons too. Thats because I've made this exchange of my WD1.

Those things about weller tips made in Bosnia and Mexico, I've saw something like that too. Fortunatelly I always manage to find Germany and Japan made tips around here. I've never got any from US.

Apparently €10 gets you:
A Cirrus Logic CS8416 chip that costs roughly €7 in small quantities
All the connectors
A 5V power supply landfill item (granted, haven't opened it yet, but there's already something rattling inside)
A powdercoated folded steel case

And it works fine. Not even a tiny amount of noise. Only minor issue is that the output level seems a bit low, but not a big deal. Ok, the PCB is really crusty, all the holes for the connector support pins are too big and the power LED is probably a class 4 laser diode, but functionally it's fine and the case is actually quite nice.

I restored a very similar one of these a few years ago. Mine is a "Triumphator". Inside it will look something like this: http://modellsammlung.uni-goettingen.de/data/html/triumphator_files/triumphatorCN.jpg (http://modellsammlung.uni-goettingen.de/data/html/triumphator_files/triumphatorCN.jpg)
The mechanics were built to survive a nuclear invasion, so it's rare that anything actually breaks inside, they usually just need a good cleaning and some new oil.

Not really buy, but got for free. 1 APC 1000VA UPS, of course has a very dead and deceased battery pack. Ar well an Eaton evolution 200 series UPS, ditto on the battery pack side, so will dig up 2 12V SLA cells to test it ( got them free as well in a collection of dead cells, looks like they just took all and put in the dud pile, 6 were perfect out of the 20).

Next is a HP2055 printer, put in a CE505 cartridge ( use them a lot, so put in one destined for refill sometime, but still has 100 odd pages left in it) and powered it up, selected usage page and it has done 18k pages. free duplexing printer, and these are from experience good for 100k before needing a new fuser roller, which i actually have on hand for another in the "Awaiting me feeling like doing this long job" pile. Likely only replaced because they went for a networked version, this is the USB only one, but I have the HP bridge for this as well if needed.

You did rather well IMHO. In fact, a "you suck  :-+" is probably in order (~$25CAN/channel @100MHz/chan.).  :o  >:D

Granted, although a modern DSO has more features, you did well.  ;)

Guess which gets used the most?:-DD That said, I won't give up my Tek 2445B any time soon (call it whatever you want, but I wouldn't shine away from the term "nostalgic gear acquisition syndrome (aka NGAS)").  ;D The adverts of the time were more interesting to me than a Playboy or other pornographic magazine at the time.  :o

Yeah, I know... What a shame.  ::) It would definitely explain why I only have lab assistants though (aka cats) rather than actual kids.  :box: On the plus side, no alimony or child support, so it can't be all bad.  :-DD  :-DD  :-DD

Guess which gets used the most?:-DD That said, I won't give up my Tek 2445B any time soon (call it whatever you want, but I wouldn't shine away from the term "nostalgic gear acquisition syndrome (aka NGAS)").  ;D The adverts of the time were more interesting to me than a Playboy or other pornographic magazine at the time.  :o

Yeah, I know... What a shame.  ::) It would definitely explain why I only have lab assistants though (aka cats) rather than actual kids.  :box: On the plus side, no alimony or child support, so it can't be all bad.  :-DD  :-DD  :-DD

Yeah, huh?  I paid somewhere north of $100/channel for mine.  (Granted this was about 12 or so years ago, though.)

:-DD :-DD
I can relate.  Now if I could just get the damned lab 'assistants' (note quotation marks) to stay OFF the bench and racks, and that items thereon are NOT toys to be batted about, chewed upon, knocked on the floor and absconded with (or various combinations thereof... ::)), life would be easier still.  I'm still missing a full sized Soldapullt that is no doubt under or behind something in an obscure place in the house.  >:( >:(

 I got one of those cheap USB microscopes Dave mentioned in the $300 Electronic Lab video. It's actually neater than I thought it would be. Plenty of working space between the base and the lens and VERY bright LEDs (you can dim them). It will actually help work with small parts for modeling as well as soldering.

That is interesting! I was eyeballing an old HP power supply but this may do the job just as well. What is the maximum current? It says 17A on the spec sheet but you managed to draw over 50A from it  :o

It was ~900€ from Elisa-Saunalahti as one time payment, but as you probably know they also have the option for 12, 24 and 36months no interest down payment option.

Not Cheap because of it's size, but as I mentioned, I love it.

It's the PURE model so no 3rd party software clutter.

I see now that the HDD spec was wrong in my previous post. The SSD is only 128GB, not 256GB, but it's still big enough for the average user.

 Where's 50 amps? He has it set to 4 amps, 13 volts. In the second picture that's 54 WATTS, not 54 amps - little LED to the right of the display shows what it's displaying. Would be a neat trick getting 54 amps out of 17 amp rated power transistors.  ;D  I wonder if it can continuously do max volts/max current since that would be 20 watts over the rating of 1000 watts.

 Just got and put together one of those $20 ESR kits. Seems to work great although even after the self calibration it seems to read WAY low on capacitors. I don't have another capacitance meter to verify but I doubt the entire assortment of ceramic caps I bought is an order of magnitude or more lower valued than marked. Could be programmed wrong for the hardware, it's the kind with a socketed micro so I can easily check and reprogram it.

 Looks similar to my microscope except mine had a flexible gooseneck and a suction cup. The bad part is the suction cup doesn't stay stuck, even to the included base plate. Or the smooth finish of my bench shelves. After it fell off for the third time I hit on an ugly solution that allowed me to solder my ESR meter under it - I wedged the suction cup under my Fluke 45 on the first shelf. That put it somewhere around a foot above the work surface and I was still able to focus it in quite nicely, and when viewed full screen on my 27" display I had no problem seeing the joints to solder, once I got used to watching the monitor and not my hands moving in with the iron and solder, that took some getting used to. I need to find a better way to mount this but not permanently - maybe screw it to a small chunk of iron or steel.

Cheers, that's why I got the stand but I must confess I was tempted to get the goose neck and screw it to the bottom shelf of my Workbench.

Unfortunately, I'm not that familiar with that model. The only Keithley's I have so far are a 228A, a 196 and a 2700. If there isn't one already, maybe make a thread about it to see who else has one for more info, compare ROM contents, etc.

 Yeah I've been following that. Since it's one with a DIP ATMega328, I can pop it out and check the settings as mentioned in that thread. It appears my problem is similar to one of the latest posts over there, and would make some sense based on the values it returns (ie, how far they are off vs what would be wrong with the fuse settings for the clock speed).

They do a pretty good job, the *hard* part is actually the process in creating it.  I found I had to reprogram the HPGL generation so that it does 3~4 passes and also had to be done on a adhesive-tape backed mylar or poly sheet (I found 0.012" to be decent thickness as I recall).

I've written a few OpenSource tools to help with the job in Linux, not sure about Windows though.

I could have sworn I had a video of the cutter doing the process but cannot seem to find it on my YouTube channel at the moment, might have to create a new one and upload.

Yes. Swivel knife.

There are a selection of open source tools around these days to help out creating your stencil. I bought one a couple of years ago to dick around with, but I haven't actually done anything other than that yet. I think there are a couple of (old) threads around here talking about them.

Some stuff arrived. Sets of boards for an arduino 3D stepper-driver code development system (identical to the set in my 3D printer.) Also some LiIon battery charge management, over-discharge protection and DC-DC converters.

While testing the display unit, I realized something about the 3D printer boards. See the last 2 photos. The two board sets match each other, but... Can you spot it?

It's no big deal, unless you want to interchange other supposedly identical boards into the set in the printer. Like temporarily for testing the other boards.  Glad I'm well aware of this trap from past experience, so always check before plugging in and powering up.

Ultimately this mistake can be laid at the feet of whoever did the PCB layout of the LCD board. It didn't occur to them that people may want to use right angle IDC connectors, so they didn't get the pin orientation and silkscreen correct for such connectors. Or, someone soldered in the wrong version connectors...

$12 odd for 120 leads in total. Quality looks good, I was expecting crap,  but they seem fine.
I know you can get them cheaper but I prefer to buy from stock in Oz if I can.

Got them from here:   http://www.ebay.com.au/itm/181863972798 (http://www.ebay.com.au/itm/181863972798)

There was a card in the package for monsterelectronics.com.au so I guess he's got a little more than an ebay shop.

My slotted are even pre-etched S/N's, and they're still like new.   :-+ Someday I'll replace the Wiha's I've for the common sizes used for electronics. I just wish they offered more profiles for electronics series than they currently do.  :'(

Although not cheap, they're made well enough they're worth the $$$ they go for IME (of course, I've gotten mine from EU sellers, which are cheaper than US sources  >:D).

I haven't tried it out yet but it is very easy to mod. The top and bottom of the aluminium housing can be easily unscrewed and there's nothing more in there but the motor, the switch and the socket

Looks like several sellers of the same gadget on the US Ebay.  Generally under 10USD.
It seems unlikely to have much power with a motor of that diameter.

I would certainly replace that ugly flat-head screw on the collet with a proper grub screw.
It must really unbalance the rotation and make runout even worse than whatever you get from the sleeve bearing in the motor.

If you want to do more with it (well, as "more" as is possible) you probably want to get some additional collets to accomodate a range of drill sizes anyway.

It probably has so little torque that finger-tight is sufficient.   ;D
Or you could use a pair of needle-nose pliers if you wanted to get it really tight.

Yeah, but you still have to have fingers small enough to hold that bit with the ugly screw, otherwise you're just turning the motor.

I use a pair of slim over the counter ~ 2 diopter glasses in front of my real glasses but part way down my nose - almost like a pair of half moon glasses. It works quite well for the fine stuff - usually on the desk and in the lower segment of the visual field but still allows me to look up (and above the extra pair of glasses ) at the DMM/PSU etc but I am then just looking through my real glasses.
With 0603 I get out the microscope.

We once printed out a nice full-color composite die plot of an early Pentium at something like 1000x(?).  We had to clear out a large section of the cafeteria to lay all the strips of paper out and tape them together.  And even with a plot 30ft / 10m square, the transistors were maybe 1-2 pixels and indistinguishable.  And I believe that was even the "shrink" ("tick" of tick-tock) version of the product.

We don't use bond wires anymore. We use "flip-chip" or C4 (controlled collapse chip connection).  Way too many pins these days to use that last-century connection method.

20kg of components for €134. 23200 IC's, about 1700 THT and the rest SMD, and 38 x 500 or 1000 pcs. PRC201 series SMD resistors (Philips), 0R33-1M 1218 1W 5%. 7200 pcs. in 133 types from the 74HC series, 6200 pcs. in 127 types from the 74HCT series and 5600 pcs. in 92 types from the HEF4000 series. Also a bunch of tubes of jellybean stuff, tubes of machined sockets and some specialty stuff. All in all 481 different types of IC's, all in labeled tubes. I've only checked a few handfuls, mostly Maxim, on Mouser etc. and some sells for €8-10 a piece in small quantities.
Comes from a telecommunication provider that were once a national monopoly, I'm guessing the R&D department. Mid to late 90's but everything I've checked solders just fine.

Some of it I'll never find a use for but much of it is really useful to have in stock for repairs and prototypes. Besides, I find that checking datasheets for unknown stuff almost always gives you new ideas for things to build or try. :)

Nope, I'll first read out the cal memory via GPIB (when I get my hands on an appropriate converter) to back it up - for all I know the calibration RAM battery is near death - I'm a bit scared of getting a rather expensive paperweight. Maybe I won't even open it up. Will see.

So far as I can tell with my limited gear: The (DC) voltage is OK, 2 wire ohms are OK, but 4 wire ohms are giving a significantly different reading then they should be. Maybe it's just some particularly obscure setting, but it shouldn't be. Will investigate.

Anyways, the user interface so far is a pain in the ass, but I'm sure I'll get used to it.

Good buy!
Mine had an active memory error when I bought it (brought the price down to my range) but I was able to get out the cal data with a Prologix and KE5FX's program prior to cracking the case,  then desoldered the nvram,   used a tl866 programmer to suck it out as well.
Put in good sockets, replaced with new re-programmed nvram,  recapped the power supply,  quick general clean and replaced the EMI filter,  as per xdevs.
All went well.

I run a small side business as an audio engineer and I have a regular gig for a choir. I used to run an LX7 as a summing mixer and do FoH and monitors off of a Soundcraft Si Compact. Two fat multis to stage, two mixers. Now one mixer and two CAT5  :-+
I will get an etherface for recording and virtual sound check though :)

Hi Remi,

Here's some info.

GPD-3303S User Manual:
https://wiki.ntb.ch/infoportal/_media/labors/gpd-3303-manual.pdf (https://wiki.ntb.ch/infoportal/_media/labors/gpd-3303-manual.pdf)

GPD-3303S Service Manual:
http://www.eltest.hu/pdf/GPD3303SM.pdf (http://www.eltest.hu/pdf/GPD3303SM.pdf)

I just bought one of these new; $400.
The adjustable supplies (ch1, ch2) work good.
The 5V supply (ch3) works but has a 9.2V 50uS spike when the output is switched on (see image).
This occurs when unloaded and loaded.

I don't like this. I wonder how bad it is. Will it damage circuits it's powering? It's a very narrow pulse (low energy). Does anyone have an opinion on this?

My GW Instek GDM-8251A multimeter was just delivered today :)

This is from that huge blast of equipment from the ITT bankruptcy. If the chip numbers are actually date codes, it looks like it was made no earlier than 2010. And it was only $120! This is one of my newer instruments. Most are 20 or 30 years old.

Cool beans - several of us here have acquired these meters. Seems like a decent DMM on this bench. Check the firmware - if it's not v2.3 you can get the new version from GW Instek tech support, just send them an email and ask for it -

services@goodwill.com.tw

PS - but you will need a GDM-01 USB cal key and a serial cable to perform the firmware update.

My meter has the 2.30 firmware. I compared it's readings with my HP3478A meter. Calibration looks good. My GDM-8251A meter did not come with the cal key. I'm now debating whether to buy a cal key just in case I need it later. A few years from now they might be expensive or not available.  I doubt that there will be any more firmware updates for this meter. I might need the key to recalibrate it at some point in the future.

By TODAY's standards. But unless the banana plug handles have a live exposed grub screw hidden back there, surely they were rated for higher voltage back in their day.

Took advantage of the recent Zoro 25% off coupon and grabbed a few goodies: Some Knipex nippers, a Knipex coax stripper, and 5 Stanley mini pocket screwdrivers.

The coax stripper is awesome. Now I don't have to suck so much at stripping coax. For $1.52 each the screwdrivers are almost disposable. Good thing since my last 2 disappeared (in the hands of my young boys I suspect.. ::)).

Nothing, dammit.
Because I drove to a local factory/warehouse to buy some stainless steel M3 button-head screws, and they were closed. It's a public holiday (Australia Day) and I'd forgotten about that. Just got back empty handed.
Oh well, tomorrow.

Edit 'tomorrow' (Friday) to add:
Fn(K!
It's not a public holiday today (I think) but on second trip there, they are still closed. Long Christmas break?
I dunno. If they weren't just 10 minutes drive away I'd have phoned first. Definitely going to phone them on Monday before wasting another half hour.

I bought 21 years of Electronics Australia magazine. For only $5.50. I don't know which is sadder, that I threw them out 20 years ago and am now buying them back or that they were only $5.50.

Do you know how heavy 21 years of EA is? Bloody heavy is my answer.

I stopped of at a Jaycar store which was quite near the pickup. Did you know resistors are now pre-packaged like Tandy used to do it? I didn't. That can't be a good sign. Both that it is as it is and that I hadn't noticed.

That's a good deal.  I see people all the time trying to sell a single issue of some non-notable magazine with a non-notable cover story trying to get $5 or more out of it.  It pays because someone out there at some point may want it and I think listings are free these days if you have a store.  Some sellers have thousands and thousands of listings, many times on products they clearly don't even have in stock, they just drop ship it from another retailer.

Welcome to the club! My first ever DSO and so far the best. ;-) My initial thought when unboxing was "it's so small" and "reminds of cheap radio-cassette-decks" - but when I got it running, it was more like "this will suite my modest oscilloscope needs for the coming years, no doubt, I love it."

I needed a 3456A because my 3457A doesn't have beautiful 7-segment LED display.   :)

That's a beauty. Plus, how often do you get a device with sequential digits in the model number?

Maybe I should sell one of my 5.5 digit meters now :P

Nice, what on earth are the dip packages that are bolted to the mainboard?

Those are custom HP hybrid circuits, likely a combination of precision resistors and FET switches.  If you look at the frontend circuitry in the service manual you can get some idea about what they're doing.

Cheers, amazing that they are bolted down, must have had thermal expansion issues to go to such extremes.

That 3456 looks to be in beautiful shape!  It's interesting how they have that clump of TO-92 transistors that are on Teflon islands for isolation, and they're connected to several carbon composition resistors, some of which on mine at least are 10% tolerance.  LOL - I can't recall seeing 10% carbon comps in ages.

I'm not certain because the few pics I took for someone a year or so ago are from above and don't show it clearly, but I believe that the custom hybrids are little daughter cards, as at least one of them appears to have flying leads radiating from beneath it.  I think they're mounted on standoffs and the standoffs rather than any pins they might have are providing the mechanical mount.

-Pat

Edit to add - yours has the same 10% CCs at the top center of the board photo.

Actually, not today but over the last couple of weeks.  500 ft of 14 ga stranded THHN wire, 1,000 ft of black paracord, 100ft of 450 \$\Omega\$ ladder line and a bunch of 3 ft heavy duty bungee cords in preparation to making and putting up a full wave 80 Meter loop antenna.  A club member gave me a good sized piece of 1/2" acrylic and another donated the use of his bandsaw and drill press to make the center isolator.  It will be nice to get back on the HF bands again.  The radio looks so sad  :'(

I got a GW GUC-2020 universal counter a few days ago. $25 including shipping! Fully functional. good condition. Plastic case a little yellowed. I compared it against my GPSDO. After a long warmup, the calibration was surprisingly good. I didn't bother fiddling with the the oscillator trim cap.

If you don't have a frequency counter, you can't go wrong buying one of these! Last time I checked, there were more still available on Ebay for $25. Another big pile will be coming soon. Three more ITT schools will be auctioned off in february.

Do I really need this instrument? No! I have a HP5335A counter. I need this just as much as I need another multimeter  :) When I saw the $25 price I couldn't resist! I may just wait until the ITT equipment blast goes away. Re-sell it for a small profit.

Details:
This is NOT a precision counter. It doesn't have an external timebase input. It has only a crystal with no temperature compensation. Even worse, it has a really bad PCB layout. See the pics. The crystal is right next to a voltage regulator heat sink. Probably why it took about 30 minutes for it to stabilize and show a good 10 MHz reading. A hot heat sink right next to the crystal is not going to help the warmup time.

Finally, It's not the best frequency counter. If you don't need extremely precise frequency measurements it'll be a good choice. What other instrument can you buy for 25$ Maybe a crappy Chinese multimeter :)

There only precision (absolute, in current source for resistance measurement and relative to each other in voltage divider) resistors in these hybrids. No active parts in there, which makes it very service friendly :-)
BTW, if you press 6, store, N digits disp, you get another digit more. ;-)

Two GW Instek 8251 DMMs, Agilent 1252b (I was tempted to grab 2 as well) and 6 sets of probe master leads (to go with all the other DMMs I have). The US reshipper I use came in real handy for combining all these items so shipping was a fraction of what it would've been. All these come from recommendations here, so I guess I need to log in a lot less frequently  ;D

Interesting.  I hadn't studied the 3456A schematics as much as the 3457A sschematics yet.  I did figure out the digits displayed and NPLC early on.  The interface is very different from the 3457A that I have.

Rescued and old Roomba 560 from gumtree yesterday, lady said it just needed new batteries. Lol.

As I suspected it needed a full teardown and service plus a new battery, filters and brushes.

It had several dozen dust bunny colonies living inside and hair wrapped around everything that moved! I doubt it has ever been taken apart and cleaned before.

Oh and because it's an American unit I got a free 65w step-down transformer which is not half bad quality. I won't need it for the Roomba for long tho as these units only need the plug, mov, 47uF cap and time delay fuse replaced to run on 240v - I'll do the mod on the weekend.

The main reason for buying it is to clean my workshop / garage floor - I was using my spare Neato xv11, but it's far too good a bot to use in the garage. That and it's lidar keeps getting filthy with dust and needing a clean.

Did the main brush motor need any attention? I have a 560 where the brushes no longer turn, and it seems from Googling about these motors have a tendency to fail. I'm uncertain how much time to put into trying to fix it, so any hands on experience is welcome!

Yes it was full of dust bunnies too, after cleaning out the motor I put some Kapton tape over the vents.

If your motor isn't turning I'd take apart the CHM gearbox as it's prolly full of garbage and all bound up, the motor itself will prolly be fine after a service. The biggest flaw in the Roomba 5xx series is the lack of sealed bearing in the CHM which lets all manner of garbage in. Once you've cleaned it, re-lube it with clear or white lithium grease.

If your CHM is completely stuffed, you can buy the motor module for about $39 USD or the entire CHM for around $59 USD from eBay etc.

My (slightly crazy) idea is to fit the entire bathroom ceiling with these (without the supplied converter) and control (dim) them individually to create a lighting and ceiling solution for the bath room. The idea is still in it's brewing stage though and I have not decided yet to go through with it or not.

If you want a smarter bot for your house, grab a new Neato BotVac model with WiFi, no more random bouncing around a couple of rooms, they actually vacuum your whole house, every square inch.... Oh and they have lasers!  ;D

Roomba's are great for a single area and not much else imho. That said, they are great for workshops because there's so little to to go wrong with them and they are dam easy to maintain. 8)

Keysight (Agilent) 34411A
It is 10 years old but was never used. I had a peak inside and there isn't a spec of dust, the fan is also spotless.
Kudo's to Agilent for the type of sticker they put on the top of the unit. After 10 years it still peeled off just fine without leaving anything behind.
The calibration is spot on - I can't believe there has been pretty much no drift after 10 years.

Somewhere I'd gotten the impression that when HP removed the fan in later serial numbers of the 3456A, this was because they'd learned that it was best to not have a fan in a precision voltmeter, but I guess 15 years later they'd forgotten that.   :wtf:   Not really picking on this one in particular, just that I've been noticing that a lot of 5.5-7.5 digit multimeters of the past 15 years DO have fans, and that seemed dumb.  (Drafts near temperature sensitive parts, leaving dust particles on the sensitive analog board, etc.)

(Though I guess the 3458A has a fan, so I dunno what to think of that.  And I am a newbie in understanding the design of high resolution multimeters)

Yeah, thats when somebody returns 34410A on lend to my office I say "Meh, no, this is not the lab it belongs, try another door". I prefer my silent ancient 3478A instead.
Or shall I convict my boss to buy me 34401A (until they dry out) or Kei2000 ? ;D

34401A in my home lab is the best DMM ever for me I ever had.
If I were in situation when I dont have any DMM and I coudnt buy 34401A (or K2000) I would rather have no DMM.

Congratulations.
The 34411A is one of the best meters ever produced in this price class and the calibration usually does not drift much at all over the years. That is why you also can read out a useful 7th digit over the bus system.

$86 worth of stainless steel, to make a vent through the wall to outside. For an air extraction system for the lab.

I'd been putting it off, trying to work out some complicated way of going into the wall cavity then up to the eaves and out there. All to avoid cutting a hole through the outside brick wall.
Finally reached the 'f*ck it, cut the bricks' stage.

Unfortunately it seems to need a bit of tender love to get it back into full working order. Does anybody know where one can get a service manual for that device?

I had it half disassembled for a first look before I noticed I don't have the right tools at hand to continue, so I can only show a photo of the PCB backside.

Wera (and Wiha) tools are top notch. The similarities in their names comes from the German semi-tradition of forming company names from the founders name(s):

Wera = Werner Amtenbrink
Wiha = Willi Hahn

I'm less pleased with Wiha lately.  A lot of their stuff is made elsewhere and I certainly wasn't impressed with their diagonal cutters.   On the other hand, I love the quality of Wera screwdrivers, and Knipex pliers and cutters.

Oh, and to stay on topic, finally put this into place on the relevant area of my floor:

Not sure if it's any more durable than a cheap bench mat, but I don't use a chair there or anything that should tear it up quickly.  The resistance is in the right range, and I'll feel a lot less bad about forgetting my wrist strap. :)

I've not found the missing jaw to try anything.

I only closed them without gripping anything (was in the process of repairing my eye glass frames, and didn't want the serrated snipes to scar up the frames). And No, I wasn't using a Gorilla grip by a long shot.

As per Schmitz' offer, if I order another pair of pliers or cutters, they'll add a replacement 4221 HS 22 at no cost.  :-\

I've bought these LED strips intended to replace CCFL tubes in TFT panels. I might have a TFT conversion project coming up and finding the right CCFL backlight inverter for a specific TFT panel isn't always easy so these LED strips hopefully make life easier. They are cheap too at around US $5 including shipping from China.
The seller has them in various sizes and they can be cut to the right length: http://www.ebay.com/itm/361624462481 (http://www.ebay.com/itm/361624462481)

Actually upon disecting the pack a little I did find the telltale crystals (potassium carbonate formed from the potassium hydroxide electrolyte reacting with atmospheric CO2, I think) but it hadn't gotten any further.  I temporarily clip-leaded a 1000 uF into the circuit for filtering and it works!
It relies on the battery for filtering. 

Anyone know how to remove those turn counter dials?  I cannot see obvious fasteners and it seems to be needing some lubrication.

BTW, the pack may be from '77, but the inside of the case has a '71 date!

I'm pretty sure those knobs are the collet type.

Pry off the front cap, there will be a nut in there that locks the knob to the shaft.

Thanks.  I then was faced with a kind of snap ring (but not the kind that's easy to remove with snap ring pliers).  Got that off and with some more prying found the turns counter was glued (!) to the panel a bit.  As far as I can tell, the way I was supposed to remove it from the shaft was with a tiny (smaller than my smallest 0.05" driver) set screw via a hole in the bottom of the turns counter which I couldn't even get into easily with the guard binding post in the way.  So the gear that sits on the shaft itself is still on there :) 
Given that the ones to tens carry wasn't quite operating, it may be just as well that I need to replace the counter.

Edit: looking at McMaster-Carr, I see .035" and .028" Allen wrenches are available.  Hmm.

It's really nicely built, and frees up some much needed desk space. Was on sale for under C$50 from primecables

Should not be hard to mount one though, using 4 M5 Rivnuts through the appropriate hole pattern into the case. Would be a good idea though to put a inner brace plate though and make sure the screws you use do not foul the PCB inside.

Alternatively a simple angle bracket and small shelf on an arm would also serve.

Those labels look good. Are they easy to apply? I've tried a couple of the Brother P-Touch label printers and they are they're rather fiddly to get the backing removed from the label tape.
Title: Re: What did you buy today? Post your latest purchase!
Post by: SingedFingers on February 17, 2017, 06:45:20 pm
They are quite difficult for me because I have banana fingers. There is a slit lengthwise down the entire reel which makes it slightly easier.

Still miss programming Intermec printers in the late 1990s. Those were much more fun :)

Post by: Cubdriver on February 17, 2017, 08:01:05 pm
The Brother P-touch label maker I now have uses tape that's got the lengthwise slit on the back now, too.  Makes them much easier to apply - peel half and get it positioned, then peel the other part.  At my previous job we had one of the earlier p-touch printers with the non slit backing and they were definitely a bear to peel.

Difficult to remove or not, they're still a thousand times easier than the old Dymo labels made on the embosser.  Spin the dial, squeeze the handle, and without fail the next letter needed would be on the opposite side. Thkthkthkthkthk-click  Thkthkthkthkthkthkthkthk-click  Thkthkthkthkthkthk-click and then near the end you'd screw up and land on the wrong letter and need to start again.   |O  that and the natural curl of the tape made them want to pop off if not thoroughly stuck down to an immaculately clean surface.

Dymo tape, the best way to stick it down was to use solvent welding, or contact adhesive.  Otherwise after 10 years all that was there was a brittle adhesive imprint, with the label curled up below it.

Ahhh, the memories! Trying to get all the letters the same shade and/or evenly embossed would give you OCD if you didn't have it already.

They are quite difficult for me because I have banana fingers. There is a slit lengthwise down the entire reel which makes it slightly easier.
Agree with Dymo labels, I have same label writer... Sometimes I use exacto knife to grab the back paper. Dymo labels that I used in last 15 years, will turn slowly darker during longer period if eposed to warm temperature. I had few stickers on the laptop, color goes from white to brown :-)

I also do labeling of extension cords (using long piece of label around wire) with Dymo.

Still miss programming Intermec printers in the late 1990s. Those were much more fun :)

Thankfully the Epson label makers have this too.

I don't think it even took that long!  I have sets of drawers with the loose curved labels sitting in the recess on top of the drawer pull.  At least they didn't go too far astray.   :-DD

Those labels look good. Are they easy to apply? I've tried a couple of the Brother P-Touch label printers and they are they're rather fiddly to get the backing removed from the label tape.
Try with sharp SMD tweezers works..

Don't forget to label the labels.

Me too, even some of their 20v (seriously marketing dept, they are 18v!) lithium tools are pretty good for the home gamer like me,  You just need to buy at least 3 of the batteries so if you are working the tools really hard, you can swap in a fresh pack when the batteries temp protection kicks in.

But demagnetizers aren't designed for continuous operation.  Is there any use case for leaving a demagnetizer operating unattended?  I can't think of any.

Presumably that is like an ordinary transformer, except that it is made of just the "E" laminations and  it is open-ended at the "working end".

Well, mostly I meant I don't even really trust the cheap switch to keep things safe if it was left plugged in :)

It is indeed like a transformer but just the E laminations, open to the top of the case.  And I guess the LED indicator is one of the variety that has good reverse voltage tolerance.

You will probably like them.  I bought two of them off of Ebay last month and they work rather well so far.  They are larger and heavier than the modern ones.  The datasheet says they are 11.5 kg (25.3 lb) but they are built well.  No flimsy stuff in them.   I have mine set up stacked next to my 2 stacked GPD-3303S supplies.    The 3020's were only $44 delivered when I bought them and they were too good of a deal to pass up.  Now I think I have enough power supplies for a while.  What would be nice is if we could get a service manual or at least schematics for them.

Intel have been so Slack in recent years that the core 2 is as fast as a current i3 for most things.

No way. Core 2 Quad may stand a chance to compete modern i3. Dual core doesn't stand a chance.
According to Cinebench, a 35W i5-520M is as fast as a 90W Core 2 Quad Q6600.
Modern (6-th/7-th gen) 15W i3 processors are as fast as i5-520M.
So, a dual core Core 2 Duo will get ~0.5x the speed of a modern i3U.
You won't get nearly as fast experience as a modern i3 on a dual core Core 2 mobile.

FYI, in Cinebench R15, a Core 2 Duo T7200 (in your Macbook) scores ~120 points, while an i3-6100U scores ~244 points.
The Kaby Lake K series i3 is competitive with the older i5s in multithread benchmarks and completely blows them away in single thread benchmarks. That is before you overclock them 25% to 5 GHz on air cooling.

I don't have any brand name known high quality ones to compare with - but in my opinion these are good. Banana plugs which I tried with these fit "just right." Well worth their price.

I wanted to play with some microcontrollers. After some time in checking some, i decided myself for The cypress psoc.
Nice choice.
On my latest Mouser order, I added a couple of PSoC 4   (http://ca.mouser.com/search/ProductDetail.aspx?r=727-CY8CKIT-049-42XX) and PSoC 5LP  (http://ca.mouser.com/search/ProductDetail.aspx?r=727-CY8CKIT-059) dev kits. These seem to me to be a great value for such capable 32-bit MCUs. That PSoC 5LP dev kit costs less than the bare chip that is on the board, plus there is another PSoC 5 series chip on the USB programmer/debugger snap-off section. The board has two $15 PSoC 5 chips on it, and costs $10.  :-+  These are definitely not designed to turn a profit, but to turn people on to the chips instead. Works for me. Now if I could just find time in my busy life to crack open the boxes and build something.

My kit is a bit bigger, but i wanted to start with something i could maybe even use for a own board. So far the Toolkit looks nice but is quite huge. Let's see how i like it once i got more time  ;)

Probemaster 4902-1 250MHz oscilloscope probe.
BNC fits nice and snug on the 465B,  unlike the TP6100 CCPs.

I found a not terribly priced power supply for my HP 8648B with the stupid broken, undocumented, third-party power supply.  Will be nice to get that going again.  I have a much nicer 8644B, but you can never have too many signal generators!

I'm vaguely tempted to try fixing the old supply anyway though, I am more confident in my debugging of switching power supplies than I once was.

Can't say I regret that - it was much more expensive, but is much more bang per buck as well. Both literally, in "dissipated Watts per dollar" terms and feature-wise, also.

Yes, this exact model. I haven't loaded it with full 400W yet (something around 300W for few minutes) but I have no reason not to trust the specs. The downside is it's loud - even with the fans on idle.

well if you're going to have that kind of performance on your desk, it's going to show somehow! :-)  I also got the add on fan kit to push my little re:load a bit further, but haven't got around to installing that yet. I suspect the little fans on that won't be that audible even at full speed.

An organizer rail for wrench sockets , but going to use it to hang scope/meter probes. It has a  nice aluminum rail with sliding plastic sections which you can adjust to have needed gaps between them to store cables/probes of different diameters. Only 9 CAD bucks and will look nice in the shack too.

Edit: Fellow Ontarians can buy it from Sayal

Interesting.  That one only goes to 620 KHz. At least it doesn't look like you don't need to use "WECo" connectors which are vaguely like 1/4" phone plugs but not quite. 
At least you'll be well set up for VLF receiving. :)

Got a monitor upgrade on my homelab workstation. I was using dual/triple monitor setups for quite some years, starting from 20"+20" 4:3, then going 30" 3008WFP with two 20" 4:3 in pivot on the sides, and then Dell U3014 + 24" in pivot here in Taiwan.

Decided finally to gamble on 4K, but since pixel density is huge issue with 99.9% of Windows/CAD software on anything below 40", went with Philips BDM4350UC (http://www.philips.com.au/c-p/BDM4350UC_75/brilliance-4k-ultra-hd-lcd-display/specifications).

Might cook short review in electronics engineering point of view. There are many youtube unboxing/gaming/video related things, but nothing about engineering/CAD use which this beast sorta designed for. At first glance real estate on schematics/pcb layout view and pixel density is great. Attached few screenshots for teaser.

Going out now to buy a VESA mount for it, as default legs are useless.

Other of my design files with that many layers and BGA's are under NDA, and I can't show them  :). Here's my LTZ1000 reference showing outer layers. You don't have much benefit from 4K for this simple little board.

I got myself a Samsung SyncMaster 2443 BW monitor from my local surplus shop for the grand sum of $25 USD.  Granted, it didn't have a base but it didn't have a scratch or dead pixel and I had a universal base to put it on.  A definite upgrade for my workbench.  I am contemplating buying 2 more to replace the 2 22" monitors on my desk that, coincidentally,  I bought from the same place.  They are attached to a dual monitor mount but I have the bases for them.  They could be spares. :clap:

I got myself a Samsung SyncMaster 2443 BW monitor from my local surplus shop for the grand sum of $25 USD.  Granted, it didn't have a base but it didn't have a scratch or dead pixel and I had a universal base to put it on.  A definite upgrade for my workbench.  I am contemplating buying 2 more to replace the 2 22" monitors on my desk that, coincidentally,  I bought from the same place.  They are attached to a dual monitor mount but I have the bases for them.  They could be spares. :clap:

I've had two 2433BW that have served me well for many years. As far as I can see the only difference is that the 2443 has USB hub, matte screen and vertical mounting. Though not a high end display by modern standards but it sure was nice back then. €430 apiece I think.

Bought a bit of solder from my local Craigslist. It was cheap but appears genuine and works very well, unlike some cheap, worthless crap I bought from China.

Cool !

I have the SyncMaster BX2450 and it is a great screen.
Looked that one over but didn't have a stand so passed it up.

Good Move!

Stands can be gotten off of evilbay for $38.  Under $65 for a 24" monitor/stand.

Bunch of pipes and batteries.
The plumbing is for restoring a Varian 936-60 Helium Leak Detector (http://everist.org/NobLog/20170224_summer_vacuum_odyssey.htm#ideal (http://everist.org/NobLog/20170224_summer_vacuum_odyssey.htm#ideal)), and the batteries are for an EM Electronics N11 Nanovoltmeter. https://www.eevblog.com/forum/metrology/em-electronics-model-n11-dc-nanovoltmeter/ (https://www.eevblog.com/forum/metrology/em-electronics-model-n11-dc-nanovoltmeter/)

The He-Leak detector has been sitting in storage over 10 years. So there are a few things that need work. All the pneumatic piping had rotted, so is replaced (black nylon tubing.)  The copper and brass stuff is for a re-arranged oil-mist scrubber on the outlets of the two rotary vacuum pumps. Yes, as shown the pieces don't mate. They will after I machine and silver solder them

The N11... I've been trying to think of some way to replace the stupid 7-NiCad battery packs with something using 2 or 3 18650s and DC-DC converters. But it doesn't seem possible without altering other wiring in the unit, and I don't want to do that. Also, running a switcher inside a nanovoltmenter, seems like a good way to inject relatively huge noise into the signal. So I gave up.  I need the nanovoltmeter working again for something (that 10 or 20M ohm resistor check) and so will just rebuild the battery packs. Except I'm starting to think buying NiMH may have been a mistake. Seems they don't like being only ever trickle charged?

Nice, my late grandfather had a late 1890's master clock. It was sold when we had a yardsale many years later(I didn't know it was sold, or to who) for not enough money. I think it sold for about $100 :( .
Title: Re: What did you buy today? Post your latest purchase!
Post by: Gyro on March 08, 2017, 09:21:42 pm
That's sad, it must have sold for way lower than its true value (not to mention sentimental value), prices have risen steeply in recent years too. Far too many master clocks were simply torn off the wall and skipped when buildings were demolished, together with all their slaves.

I've wanted a Synchronome since I was 11 and first saw the one at my senior school. I'd more or less given up on getting one until I found this relative buy-now bargain, so I'm still grinning like a Cheshire cat (which coincidentally is where it came from  :)). Hard to believe that a pendulum clock can be that accurate, as near as I can judge, within <100ms since Saturday! Even the original guarantee of <2s per week is pretty amazing.

Not exactly today, but very recently. Philips/Fluke PM 9010/091 probes from german ebay from seller c_h_r. 25€/pc. Very bold quality. Better than chinese 10$ probes.
Look at the photos. There are also PM9001 which I bought years ago on fleamarket for 40€/pack. Also good quality.
This seller seems to have a lot of these. However he is out of office now. He has CLMT.de website, however temporary unavailable.

My mini-circuits order arrived!  ZX90-2-19-S+ (2x multiplier), VBFZ-3590-S+ (Bandpass), ZX05-83-S+ (mixer), to replicate the cheap approach to a tracking generator for my HP spectrum analyzer, as in http://www.kerrywong.com/2016/01/10/building-a-tracking-generator/ (http://www.kerrywong.com/2016/01/10/building-a-tracking-generator/)

Only difference is that with my HP 8562A, the LO starts at 3.9107 GHz, so I set the signal generator to 1.95535 GHz.

Pictured is a high pass filter I had lying around. (Yeah, I need to get GPIB going again)  Also that's not having subtracted the trace with the mixer output directly connected to the SA input, oops.

Your pulse generator has the advanced synchronome gravity oscillator drive. Make sure that your hipps are toggling :)

My GPSDO is slightly more accurate. My wife would be very unhappy if I decided to hang it on the living room wall.

Haha, absolutely, a detached gravity escapement. I do have a Hipp Toggle (a PO36) but way less accurate (too many contacts stealing power from the swing). I can't believe how stable the Synchronome is - I haven't touched it since the weekend and every day it's been audibly spot on compared to two radio controlled clocks. My Quartz watch has gained a second in that time!

Nice to know there are others with other strings to their collecting bows (don't get me started on laboratory balances :D)

I finally got one of these supplies at a decent price.  Was "for parts or repair" and I don't plan to power it up until at least having a look at the insides, 3000 V can fry things pretty fast.

Also planning to replace the MHV connectors with SHV if it's practical, as those are more obtainable and safer too.

Very nice!  It never occurred to me to swap in SHV connectors.  That's a good thought.  I've been half heartedly looking (without success) for MHV terminated leads for at least a year now and haven't stumbled across any that were reasonably priced and not trashed.

I'm quite confident that it is.  >:D
Although I'm a bit less worried about these than the high power stuff which was in a better position to spew its guts all over, I'm thinking about whether I want to just let it be, spend a lot on new capacitors, or give up on the project :)  Could definitely be looking at $120+ to spend on new capacitors for a $50 power supply.  Quite possibly worth it in the long run, everything about this (except the transformers) is fairly non-exotic discrete parts (if you include a 1N825 and a bunch of precision wirewound resistors as non-exotic) that is quite repairable.

My impression is that the lifespan of the PCB-filled paper capacitors is really quite good, but although the DE-5000 I have is decent, it's not equipped to test leakage at higher voltages like old time capacitor testers did.  And I know the non-oil-filled paper capacitors are problematic in just that way.

Where I work I recently removed an old master clock system. It used a carrier current system to set the slave clocks. The signal was coupled to the 480V building wiring through a bank of PCB filled caps. They had been in continuous operation for nearly 50 years. I tested a few of them and they were still good. It seems like the more hazardous it is, the better it performs :)

And that brings up a reason to keep them and another to replace them. The old caps that I removed filled up a 5 gallon plastic bucket.  Getting that bucket picked up by the hazmat recycler cost $200! If you choose to properly dispose of the old caps, it's going to cost you some $$$ The problem with keeping them is that if one pops, you'll have PCB oil all over your workbench!
Title: Re: What did you buy today? Post your latest purchase!
Post by: Cubdriver on March 12, 2017, 08:23:16 am
As far as the chlorinol filled cap, as far as I'd be concerned I'd say if it ain't broke, don't fix it.  Just leave it alone.  And I wouldn't be hugely fearful of the small amount in the cap.  Just don't go cutting it open and using the PCBs as massage oil, or mixing them with vinegar to put on your salad.  People lose their minds over things like this and asbestos and mercury.  Remember that dose is important.  If any of them were as deadly as you'd believe based on the over reactions they engender these days, you already have died simply from reading the label on the damned cap!.

Are PCBs somewhat dangerous?  Yes, they are.  Is it good that they're no longer being used?  Yes, it is.  Is it necessary to evacuate everyone within a ten mile radius and air drop in a hazmat team to remediate because you have a device with a sealed cap that might contain a few ounces?  I don't think so.

I'd be surprised if that cap wasn't fine (and if those caps were problematic, I'd expect to have seen some mention of it somewhere).  Find out what if anything ails the supply, fix it and enjoy using it.

Title: Re: What did you buy today? Post your latest purchase!
Post by: SeanB on March 12, 2017, 04:04:04 pm
Easy test if that cap is failing is to look at the seal between the terminal and the case. If glass, do not bother till it rusts apart, if it is rubber then beware of any liquid visible there as the rubber degrades.

There are still plenty of power transformers in use filled with PCB oil. Because the regular oil change equipment that takes the old oil out, filters and dewaters it is not cleaned between uses this means all of the transformers ( even brand new ones) will have some small volume of PCB oil contaminant in them, and older ones ( typical age is 60 years, simply because they do last so long in service) will never get all the oil in the paper insulation out ever. Then look at all the older PFC capacitors in use in utility switching yards, and still in use, full of PCB containing oil. Then look around for 40 year old wire, if it is oozing a green liquid that is also PCB based plasticiser in the PVC wire sheath, reacting slowly with the copper wire. I work with it daily, plenty of it around all over the world.

LOL - I apparently managed to either miss or forget that you'd gotten one!  (though with the lot of us buying stuff right and left, I can barely keep up with my purchases, nevermind everyone else's!)  It was listed as 'used', and described as 'tested for key functions', but who knows what exactly that means...  None of the photos show it lit up, so it's likely a pig in a poke.  Cosmetically the pics show it as a bit rough, but it has the feet and other than some scuffing and stickers it looks to be in decent shape.  No checkmark in the 'battery option' box on the rear panel sticker, so just a plain AC line powered meter AFAIK.  I'll know more when it arrives - who knows how badly this storm will bugger shipping up.

There are two Fluke 8375As on the shelf downstairs, too.   :-DD  I'm really going to be the MeterMeister if I ever get all of the damned things up and running!

Scored a NOS weapon grade keyboard from local computer warehouse for $10, the legendary buckling spring keyboard.

The seller let it go since he claimed its no longer can be used at today's laptop anymore  >:D, but at that price as it's "branded".  ::)

PS : Anyone know how to clean the heavily tarnished 5 pins of the DIN connector without destroying the plastic housing ? (photo attached)
I thought you could attach a different cable with ps2 connector (purple small din) that should still work with an adapter on usb. Have to search but i thought i still have such a keyboard somewhere.

I would probably go with a very lightly abrasive paste like Simchrome or Brasso or toothpaste perhaps inside a piece of just slightly larger insulation - placed over the pin (one at a time)  and spun by hand - then a really good clean with IPA.

And after that, I would verify the cleaning action by running a 4 wire milliOhms measurement across all pins of socket/plug connection. For this solder the leads from the DMM to the respective solder tabs on the plug, respectively socket. Then compare your measurement with the data sheet - which does not give any mOhms contact info.  :palm:  |O
Therefore some of my measurement results on an old and well stored 5 pin DIN connector:
Contact resistance after years of storage (slight oxidation is visible): 35 mOhm
Contact resistance after cleaning with "Kontakt 60" (a popular deoxit fluid in Germany): 7.6 mOhm.

There you go.

I have bought a lot of odd chips the past week:

* AT91SAM9260B-QU 180MHz ARM926EJ-S MPU in QFP-208
* MT48F32M16???? 64MB x16 PC-133 SDR SDRAM in TSOP-56
* K9F2G????? 256MB x8 SLC NAND in TSOP-48
* K9F4G????? 512MB x8 SLC NAND in TSOP-48
* V3s 1.2GHz ARMCortex-A7 MPU with built-in 64MB DDR2 SDRAM in QFP-128
* AXP203 system power management IC for V3s in QFN-48
* LM3671MF-1.8 1.8V synchronous buck converter in SOT23-5
* M80C88 16-bit MPU, along with the full IBM PC XT chipset, in DIP
* IS61C256AH-12 SRAM in TSOP-28, a lot of them
* SN74HC138 decoder in TSOP-16

So I basically bought parts for three SBC: an ARM926EJ-S one with 64MB RAM and 512MB NAND and 4MB NOR, a Cortex-A7 one with 64MB RAM and 16MB NOR, as well as an IBM PC XT clone with 1MB of fully static RAM

Damn, how did you know I measure those pins with 4 wires at sub miliohms resolution ?  >:D

C'mon, that thingy probably is now considered an antique, and also collector's item. Cleaning that darken DIN pins is for aesthetically reason, not technical at all. Those dark/black coating on the brass pins will just conduct fine when inserted into the DIN socket.

Makes sense in terms of prices. And IN18 prices are ridiculous. But when you buy IN12 which are cheap and available in large numbers, these nixies are made with so damm long life time. 100 000 hours no exception. USSR made them with insane lifetime margin.

That reminds me of my scavenger hunt last week on a fleamarket that is kept once a year and where leftovers are sold from a smt place business.
My score this year:

Panasonic SMD elco's:
330uF/16V
4u7/50V
10uF/50V
470uF/16V

TH Fujicon (is that a decent brand or should i scrap them?)
2200uF/63V

and some bags with RJ45's, Phoenix 8pin connectors, dc-dc converters,
8 pcs of AD734AN (no idea what to do with those, anyone have an idea?), DS1225, 7808s

Just to stock up for my projects the next 25 years  :-DD  if the elco's survive that long , I already have quite a collection from past years hunts.

Thanks. I just opened the clock and it comes with a built-in audio device :) After all this years I still remember the sound, my grandparents had such a clock, too (each full hour: dong - dong - dong...). Will add some solenoids.

Not that I'm aware of, but a lot of the 80s era HP gear that I have calls for one in the troubleshooting section, so I've had a search set up for quite some time.  This one showed up in what looked like decent condition for a low price relative to what most wanted for them, so I decided to grab it. May never really need it, but it's small and was inexpensive, so why not have it handy should the need arise?

Cool - thanks. 

I presently know nothing about signature analysis other than it being called out as a troubleshooting technique for the equipment I mentioned earlier.  I got the manual scan from Keysight, so the next step is to read it and try to retain what it says.  The analyzer is in good physical shape, and everything seems to be there (some that I previously saw and passed on looked like they'd been dragged a few miles down a gravel road), so this one must have been in a lab somewhere I suppose.

Funny enough, when i was doing electronics training they had a test system that would simulate faults on the board for you to trace. As they also gave you a simple scope, function generator, multimeter and assorted test leads, along with nearly a week to play with the system, I actually did manage to find all the simulatable faults they had ( there were 8 CO relay contacts to either short or open parts of the circuit) on there, and set up the system to use itself as a signature analyser, and consistently got a test score of perfect, and a time under resolution of the system ,being able to diagnose and enter the 10 simulated faults they tested you on, with the overall time being 0.0 minutes, as I was able to do each section under the 6 second resolution of the controller. Was a little disconcerting to the instructor, brand new test system, brand new training manuals and us being the first ones to use it. the test was supposed to be an hour long, as the instructors had taken around that time to do it.

They strongly discouraged us from turning the cabinets over, undoing the screws and looking inside, though of course as there were 30 students in the class, all around the room, and one instructor being harried by all and sundry, there was kind of lack of supervision. Z80, 32k of ROM, 2k  (6116) of RAM, UART and Z80 PIO, a ULN2003 relay driver, and 8 Omron relays were on the board, along with a RS422 interface to daisy chain it along, and each board had a jumper set for termination. A little bit of logic and a 74C922 keyboard encoder, and some 7 segment decoders and another uln2003 as led drivers for the multiplexed 4 digit 7 segment display, and for the red and green pass/fail LED's on the front panel.

Power supply was a transformer with 3 secondaries, providing +-15V rails for the analogue stuff on the test boards, 12V for the relays and DUT board as well and 5V for the DUT, all being 78/79 series regulators on a common heatsink, and another 7805 for the logic board ( wonder why that was, board ran pretty cool) alone.

They were somewhat surprised at the scores, next lot only saw the system on the test day, rest was theory and practical on breadboards.......

Received these little boards. They allow you to tap into 6P6C or 8P8C connections/lines easily, either to inject a signal or look at one.

I've already got a C-mount camera, but the adapter I bought from AmScope was completely baffling.
I thought this was the right one: https://www.amazon.com/gp/product/B005PONV98 (https://www.amazon.com/gp/product/B005PONV98)
Neither end fits in the 3rd tube for the camera (or the eyepiece holes, either).
And neither end fits a camera C-mount, either.   :-//
Title: Re: What did you buy today? Post your latest purchase!
Post by: Housedad on March 28, 2017, 04:58:52 am
Yeah, I nearly got caught on that, too.  It seems that that adapter has a threaded end that fits in the microscope head instead of the adjustable tube assembly that comes with it.  HOWEVER,  it only fits some of the models.  If you look at the Amscope website for that adapter, http://www.amscope.com/accessories/adapter/5x-c-mount-lens-adapter-for-microscope-video-cameras.html (http://www.amscope.com/accessories/adapter/5x-c-mount-lens-adapter-for-microscope-video-cameras.html)  you can read where it says " *Note: this will not fit the "TP" version of the SM series.*".  This includes all of the simul-focal heads and some others like mine.

The  SM-XXTP series scopes do NOT accept a threaded adapter.  They have a dovetail ring with setscrew that the original adjuster tube that comes with the scope just slips into and is held with the setscrew.  Once I realized the difference, I checked my scope and sure enough, it had the dovetail.  But mine is not a simul-focal or TP version, yet it has a dovetail setup.  It seems that only a few of the types of heads can take the adapter you linked to.  I was not able to find a adapter that would have a dovetail to just be mounted directly to the scope, so I ordered the adapter in the picture above that just slips into the adjuster tube the scope came with.   Not ideal, but it's all I can do. 

I wish Amscope would have made a page that would have made it more clear.   But, they did make a couple of vids on youtube that are handy and one that shows the screw in type adapter and you can see if yours is like that or not.

How to install a AD-C20 adapter (same adapter you have)  to a SM microcope.
https://www.youtube.com/watch?v=ZsQJZ0I-R0I (https://www.youtube.com/watch?v=ZsQJZ0I-R0I)

This one shows how to use, focus, and adjust a SM microscope head.  It shows how to set it up so that the image stays in focus through the eyepieces throughout the zoom range and how to use other controls on it.

Bought an Atten 858D+ and it arrived this afternoon - yay!

Got it for a good price (A$95/free postage after a 25% discount voucher from eBay - you beauty!). :)

It was from a local supplier - well the stock was held locally, but the seller was in Hong Kong, which meant I got it within 2 days.

Straight away I tested the earth connection - surprised to find the case was earthed all around - have the manufacturers lifted their game here?  :-//

One 'fault' is the Australian power cable provided does not have the obligatory insulation at the base of the live & neutral pins - I can live with that or I may change it as I have other cables lying around here somewhere.

Have yet to crack it open and inspect the innards for faults (after I revisit Dave's video and the relevant forum threads to remind myself of the possible faults before I fire it up - and as Dave says - Don't turn it on, take it apart!).

I also ordered a Multifunction Tester - TC1 but that will be 4-6 weeks wait until I get my hands on that (from China as if you hadn't guessed  :palm:).

I could have bought the 'no-frills', sans case, testers much cheaper but I liked the case and the colour screen is cute (but not necessary).  :-+

Edit: Bugger! - Forgot about an SMD testing pad  :palm:
Oh well, it will still be useful (perhaps the SMD pad is on the PCB but just isn't exposed through the case - ever hopeful!). :-//

It came with a pair of Kemmler silicone instrument cables and a pair of Hirschmann test tips.

Item 2: Fluke TL71 test leads, used

Mid '84 sounds about right given the 8401 code on the Intersil chip and the 419 (which *might* be a shortened date code) on the nearby RCA part.

Just give it some good time on a dim bulb tester, bit by bit increasing the wattage of the bulbs while watching for signs of things running amuck. Old ecaps have a worse reputation than they deserve. Those on the PSU might be worth testing but the others I'd leave alone until proven otherwise.

OK, I decided to be their Guinea pig.  I ordered the new Digilent Digital Discovery with a high speed header.    Hope it works like they say it does and no horrible bugs infesting it.  I guess I'm one of the first 100, as I got the header for free.  How new is it?  like 11 days since launch.
Since  I've never used a logic analyzer before, maybe you folks can help me review it in another thread.

This one features a Signetics CR999NC and a TI SN10091BP as the only DIP8's like LM358.
And there is a DIP14 MM74C00N from National Semiconductors.

The Signetics states »8415« and the NS »P8408« as additional markings. So 1984 seems to be somewhat logical :)

I don't even own a tube tester, but I'm realizing that I don't really need one if I'm willing to check tubes slowly.  Between a low voltage supply for heater, a 100V bench supply for plate, one DMM for plate current, another DMM (with a good uA range) for grid current as a check for gassy tubes (grid tied to cathode via the meter), I can reasonably check small tubes against one or two points on their datasheet curves.  At least I checked a known good 12AX7 and got what I expected.  I should probably also check with an ohmmeter for shorts to be complete, first.

I guess in a pentode/tetrode I could figure out screen voltage from the datasheet, but I guess for a first approximation I could just tie it to the plate.

Also, something I bought today (HP 411a), for not a lot more than sometimes how much the (included) old HP power cords seem to go for these days.  It has a synchronous-motor driven opto-mechanical chopper in back to modulate the chopper amplifiers 4 photoresistors!

Yeah, scrubbed it right off this morning with isopropanol on a kimwipe.  There are some scuffs on the paint on the outer case, but I don't mind.  Certainly in better condition than a lot of things I've paid a lot more for.  It clearly has some out-of-spec components, the bias adjust is cranked way over to get it zero-able.  Ironically though, this incadescent lamps and motor-driven interrupter may have a longer lifespan than later neon-lamp choppers.

https://www.youtube.com/watch?v=n0kixB-fFM8 (https://www.youtube.com/watch?v=n0kixB-fFM8)

At the end of the video you can see how it looks like inside. Very clean and neat, and built like a brick. It has no manufacturing year label or any other label, except what you can see on the front (it is in German, eBay says made in Germany, was sold from Hungary). I guess it was built before I was born and might still work when I'm long dead.

Do you think I can use this to determine the anode resistor for my Nixie project? They are running at 170 V and 5 mA, but the resistors in it look like they would even survive a short with these values (> 1 watt rating?). The case has a ground connection, which is a good idea for additional safety, and the resistors look pretty good isolated from anything. Would be easier than using a potentiometer, and I don't even have one with decent power loss rating.

Another good eBay deal, a Hitachi Oscilloscope V-202 20 MHz, condition like new, everything works, EUR 50, which actually arrived today: http://www.ebay.de/itm/292047473452 (http://www.ebay.de/itm/292047473452)

Good for me that the seller doesn't know anything about scopes, so the auction description and images were not favorable and I was lucky. I need this because of the nice X/Y mode. It has even an intensity input on the back for this. Modern digital scopes just can't do this very well. A quick test:

I suppose it depends on the clearances inside the decade box (between switch contacts, component leads, etc.).

Which microscope camera is it? Most likely you will find the software on the manufacturers site :)
Nowadays a lot of people do not even own a disk drive anymore and usually the software provided on disk is outdated anyway.

Other software should be usable as well. Most likely you just need the drivers and then you can capture via any webcam software.

Thanks for posting that. I wasn't aware of Icy. It looks good.

Back in the day (mid 80's to mid 90's), NIH Image on a Mac was the go-to microscopy/imaging software in the Biosciences. That evolved into Java based cross-platform ImageJ which is still in use I believe. But Icy looks amazing. It makes me realize how far things have come with microscopy image processing over the past 30 years. I feel old. :-\

Yes, Icy seems to be a true colossus :) Have not really played a lot with it myself, but a more in depth investigation is on the short list!

ImageJ (more precise: Fiji) is what I use occasionally to extract 3D geometry from Dicom scans. Currently I am struggeling with a high resolution micro-CT scan - post processing uses a sh!tload of RAM and CPU time...

Help, I'm not only cursed with TEA, I also have VIA (vintage iron addiction)  ;)

Just got this WWII vintage 15 inch shaper back into action. It's a late Swiss VonRoll "Original Schaerer" SH-400 Shaper/Schnellhobel/Schnellhobler. Bought it last summer on tutti.ch for a good price (13ct/kg  ;D), after some old toolmaker had died and the relatives didn't knew on how to use it and thus wanted to get rid of it ASAP (a somewhat familiar story  ;)).
(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=304741;image)

Since it had to be transported trough some doors and inside my van, I had to disassemble it as much as possible. Thereby it arrived more or less as a parts kit. Unfortunately stupidMe tipped over the main body casting during loading which cracked the clutch hinge. Fortunately I was able to repair it using an oxyacetylene torch and some silicon bronze (CuSi3Mn1).
Finally got everything back together this weekend and could make my first chips on that machine. Because it's nice to watch in action, I made a video of it:
https://www.youtube.com/watch?v=luVJUtchxT4 (https://www.youtube.com/watch?v=luVJUtchxT4)

Shaper was build sometimes around 1948, I believe, production of this kind of machine started around 1940, during WWII. It's in beautiful condition, has 6hp 3phase motor installed and weights around 1600kg/3200lb fully assembled (don't ask me how I got that transported inside my van ;D ;D ;D ;D). Other than that, it's rather compact and can remove metal like no other machine I have. Found some 1cm wide and 1.5mm thick chips inside the oil sump  :D. Also got tons of HSS tooling, the vice and a gear cutting fixture along with it. A great addition to my Maho, where the servo controller is still bitching (my next project, TCA280 replacement board Rev 3.0 :P)

Also scanned the 70year old manual, since it was heavily used and deteriorating. It's available here:

It's interesting how things work.  I decided to get back into electronics so I would have the test equipment to verify a moderately complicated VFD control panel I designed and built for the Bridgeport.  My heart is in the iron and steel.   Electronics study is a means to the end.

Finally made the leap to get an oscope, having learned on Tek in the military, but worked at HP had an affinity to Agilent.
But first I want to thank many people on here, I read a lot but never post, and I saw many positive comments on the 54622D video Dave did, and found a good deal.  Acquired the unit seen in the pic for $250 on ebay, including 1 probe and the associated logic analyzer cable.  It's flawless, no damage, and recently calibrated, so quite the score in my opinion.   I am excited to get back into some deeper design work and troubleshooting.

Cheers!

These old machines are just beautiful (if you have the space)! I own a small lathe and am desperately looking forward to getting an old Weiler, or Schaublin as soon as I can move into something bigger :) These things tend to be so much more affordable as soon as heavy moving equipment is mandatory.

For today, I could not help but give in to my gear acquisition syndrome once more.
This NOS Voltcraft 6010 was too good of a deal to pass! That is the model my dad still uses today and it is the same age as me - little nostalgia here...

Here is an article (German!) on the 6010 (http://www.meilensteine-der-elektronik.de/meilensteine-einer-erfolgsgeschichte-a-521815/).
Curious enough, the following model from 1984 (model 7905) looks almost identical to the Fluke 8020B that was also built from 1984 onward and I wonder if there is a connection between Fluke and the Conrad Electronic label / brand Voltcraft.

If you are interested I will do a tear down as soon as the beauty arrives.

Yes, I still have an identical one, marked BTC. The display is still in good shape despite kicking around in the boot of the car at times but a bit drifty. Definitely oriental in origin, ICL7106 based.

A new multimeter, some small clips, better leads for the multimeter (The ones that meter comes with are questionably loose with mine), extra fuses (RS doesn't sell the 12A 250V fuses :o) and jumper leads. This isn't the last time I'm going back, but I'm burned out right now ;).
The new leads aren't what I would call substantial, but I trust them to stay in the meter, compared to the ones it came with. That has to be the only downfall with the 2200087 meter, if mine just isn't bad luck.

More at the budget end, I just got a couple of 7 decade resistors and a 5 decade capacitor from Gerry Sweeney (http://gerrysweeney.com/seven-decade-programmable-resistor-a-low-cost-solution/). Affordable and arrived pretty promptly, after seeing them mentioned here. They look just like the pictures on his website :)

(http://gerrysweeney.com/wp-content/uploads/wppa/124.jpg?ver=1)

They're not for anything very specific, they'll just go in the bin of "better than a pot" solutions for those times when I'm playing with multiple parameters at the same time (too much time spent trying to get noise, power consumption and usually frequency all in the right zone).

Also, I got my second 24V submersible water pump yesterday. I ordered a 10A/12V solar regulator from "ledsolar" (http://www.ebay.com.au/itm/10A-LCD-Solar-Panel-Battery-Charge-Controller-12V-24V-PV-Temperature-Regulator-) on eBay but the delivery turned out to be a pump. So I sent it back. "ledsolar" re-shipped the correct item from their local warehouse... which turned out to be another water pump. I have cancelled and asked for a refund. Now I'll order a not-quite-as-good regulator in the hope that it will actually be a regulator...

Yes, it's in good shape. There's a few issues to fix inside - apparently most of these buddys suffer from their age. Apart from noisy pots, this one has occasional flickering on horizontal, looks like output stage or power supply, not yet investigated.

Purchased a $22 HDMI switcher with picture-in-picture. It came with a power brick and an IR remote.

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=305668;image)

Pretty amazing, considering that these used to be > $1000 not that long ago...

Taking a look inside, it's based around a Silicon Image (now Lattice) SiI9687A, with a small STM8S00 SK6T6C MCU, and some discretes, connectors & two VRs.

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=305670;image)

The specs for the device say full 4K HDMI, but the chip specifications only support 4K at 4:2:0. Not too bad.

The MCU communicates via I2C. The 9687A comes with "pre-programmed HDCP keys and Key Selection Vector (KSV) stored in the on-chip non-volatile memory”, according to the data sheet. Has quite a few features that can be controlled over I2C, but the "Programmer's Reference" isn't as easy to find... Of course, the basic functions could easily be sniffed off the bus.

HDMI is such a ground loop disaster. I’ve actually seen someone draw an arc off the shield when plugging in an HDMI connector.

It's amazing that they actually can make a profit off this for $22. Take a look at the mis-alignment of this SMT transistor. Wonder what their rework percentage is fresh off the line...

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=305672;image)

No EMI gasket on the metal enclosure, so I’ll bet this doesn’t pass Part 15.

Can’t say that I’m anywhere near as impressed with the power brick that came with the HDMI switcher:

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=305674;image)

Got to love that PCB-trace “fuse”. At least they have a fairly wide isolation between AC/HVDC/LVDC. Looks like they’re taking line AC & putting it through a bridge rectifier. At 240V in, they’re dealing with almost 350 volts DC on this PCB! At least the cap immediately after the bridge rectifier is rated for 400V.

Looking inside these cheap power bricks always makes me nervous.

Bought (yesterday sorry) 10PCS IC GAL22V10D DIP-24 LATTICE GAL22V10D-15LP. From China and hopefully they are the real deal (ahum).

Bought it last week; it arrived today.  Yet another boat anchor that I need like a hole in the head, but I didn't have one yet, have been watching for a year or more, it's interesting and it has glowing orange numbers.  And the seller packed it perfectly - easily the best e-bay packing job ever - immobilized in the box with ethafoam blocks that were glued in place.  I had to open the top, flip it upside down and wiggle/lift the box off of it - there was no way I was lifting it out without someone else holding the box down.

May I present (drumroll.........)

the HP 312A Wave Analyzer/Selective Voltmeter (it went by both names during its lifetime):
(https://photos.smugmug.com/Electronics/HP-312A-Wave-Analyzer/i-NGDBf4h/0/XL/HP%20312A%20Wave%20Analyzer%2002-XL.jpg)
(and yes, it took a few minutes of playing with the fine frequency adjustment to get it to read 12.34567 MHz)

And the shipping box:

The impressions left in the foam by the side castings are visible, as are those left by the feet (all five of which were present)on the bottom blocks.  The loose cardboard with the flat blocks on it was placed atop the instrument to space it away from the box top.  The flaps were also spot glued with hot melt to add rigidity to the box.  Best evilBay packing job ever!

Neat!

Just stumbled upon the operation and service manual from 1971 hosted by Keysight (http://literature.cdn.keysight.com/litweb/pdf/00312-90004.pdf?id=1866650) - scan quality is aweful, but I guess its better than to have no service manual at all ;)
Also the HP site has some vintage articles on this:

Yep, a beautiful bit of test gear there cubdriver!  :-+

In addition to my test gear score, while in Portland I visited a closing Radio Shack and picked up a few things to fill out the parts drawers. Even at 60% off,  the passive compoments and most ICs where overpriced - but I did pick up some bridge rectifiers, knobs, IC sockets, and binding posts for cheap.

I also stopped at a Fry's to check on their Keysight closeout deals. I ended up picking up a U1177A module for $29 to connect up my eBay U1252b to my iOS devices.

The radio & communications museum had a swap meet today, but I didn't wind up buying much because I spent most of the morning taking the Technician and General Ham license tests - managed to pass both, too, so will soon be joining the ranks of the radiators here on the board.  (Just what I need, right?  ANOTHER pastime that presents impetus and opportunities to obtain even more boatanchory equipment!!)

Anyway, the vendors were mostly cleared out by the time I finished, so all I actually bought was a B&K 520B Transistor Tester (complete with pilot's operating handbook) from the museum.

I then saved two things from the dumpster (for one I literally dumpster dove as it had already been tossed - we have one guy there who's inclined to toss anything that isn't nailed down, and when gear on the swap meet table doesn't sell, he's ruthless.  I rescue more of it than I probably should...)

The first, simply fished from the trash can prior to its walking the green mile is a Robinair temperature tester.  I think it's a piece of HVAC test gear; it has three temperature sensors and a meter that can be switched to read each of them.  Could be interesting to use for measuring inlet and outlet temps of instrumentation or my heating system.

It was of course immediately subjected to a rigorous inspection by the QA department.

(https://photos.smugmug.com/Electronics/Misc-test-equipment/i-Kmf3rjX/0/M/Robinair%20Temp%20Tester%2002-M.jpg)

The second was an old, ratty looking GenRad 1231B Amplifier/Null Detector.  This one was already in the dumpster, but I figured even if it's beyond repair, it could be parted out and has some good knobs, a meter movement and other things.  (Yeah, I know, I'm pathetic.)

And lastly, I've been meaning to try playing with some surface mount stuff, and a chance to get a soldering iron that should serve that purpose nicely presented itself, so I grabbed that as well.  (We decided to call it an 'accessory' to the transistor tester and include it in what I paid for that.)

Thanks!  You should go for it - it wasn't as difficult as I feared it would be.  I went to the museum Ham Club meeting last month and met one of the guys who is very active in trying to draw new people into the hobby.  (Several of the regulars at the museum have been after me for a few years to get a license.)  He corralled me after the meeting to encourage me, and the following week left a copy of the ARRL's Technician License Manual for me.  After reading that, I got my hands on the General and Extra License Manuals and had gotten most of the way through the General when I found out they would be doing an exam session at the swap meet.  I spent a few hours Friday night taking practice exams for the Tech and General until I was passing them consistently.  Most of the difficulty for me at least was memorizing the operating rules and that sort of thing - the electronics part I pretty much had down.

Get your hands on those manuals and study them for a while, and with the background you seem to have I bet you can pass the exam(s) without too much difficulty.  The extra is going to take some more work, but I hope to take a crack at that some time in the summer.

Yeah, that's the tough part, operating rules and the specifics related to them. The electronics usually goes fine on the practice tests I've done. I'll get there in time.

A laser cutter. Broken, of course.

It's only one of those fabulously awful K40 machines, but is at least shiny and unused : the original buyer had plugged it in and it went Bang. So it was half price and had the additional benefit of a fault to fix.

The seller was quite correct : the only visible problem was a black mark on the PSU pcb where the fuse had terminated with extreme prejudice. Magic smoke was left all around. It turned out to be a short-circuit bridge rectifier and was replaced with a similar part from a faulty wall-wart power supply. I think it took longer to locate a part and some suitable fuses than diagnose the problem.

A few hours later, it's running and charring things. Now I can spend happy hours fitting all the features that the cost-reduction engineer took off.

Friggin lazers!!!

Very nice! Beware to not run the machine unattended, there will be a fire you did not anticipate. That is more or less guaranteed (at least all the people I know owning a lasercutter have to deal with that from time to time).
Also, arrange for proper venting for the sake of your own health :)

Most of the difficulty for me at least was memorizing the operating rules and that sort of thing - the electronics part I pretty much had down.

Get your hands on those manuals and study them for a while, and with the background you seem to have I bet you can pass the exam(s) without too much difficulty.  The extra is going to take some more work, but I hope to take a crack at that some time in the summer.

Yeah, that's the tough part, operating rules and the specifics related to them. The electronics usually goes fine on the practice tests I've done. I'll get there in time.

Good luck on the extra exam.

The radio & communications museum had a swap meet today, but I didn't wind up buying much because I spent most of the morning taking the Technician and General Ham license tests - managed to pass both, too, so will soon be joining the ranks of the radiators here on the board.

Congrats, Pat! That's been on my bucket list for quite some time.


Thanks!  You should go for it - it wasn't as difficult as I feared it would be.  I went to the museum Ham Club meeting last month and met one of the guys who is very active in trying to draw new people into the hobby.  (Several of the regulars at the museum have been after me for a few years to get a license.)  He corralled me after the meeting to encourage me, and the following week left a copy of the ARRL's Technician License Manual for me.  After reading that, I got my hands on the General and Extra License Manuals and had gotten most of the way through the General when I found out they would be doing an exam session at the swap meet.  I spent a few hours Friday night taking practice exams for the Tech and General until I was passing them consistently.  Most of the difficulty for me at least was memorizing the operating rules and that sort of thing - the electronics part I pretty much had down.

Get your hands on those manuals and study them for a while, and with the background you seem to have I bet you can pass the exam(s) without too much difficulty.  The extra is going to take some more work, but I hope to take a crack at that some time in the summer.

Your homebrew gear doesn't have to meet that spec.
Besides over here the FCC is ineffective in enforcing their regulations.
I am not talking about the CB mess I am talking about it taking over fifteen years to get a jammer into court.. Add to that no real teeth in our emission rules when it comes to radiation from switchers and such.

Everything lately seems to be parts to have fun repairing old stuff:

I bought a Sams Photofact for an early-1960s Emerson 925B FM-only table radio that I'm doing some cleanup and restoration of.  Also some capacitors and an inline fuseholder from Digikey.

(Also reading through Elements of Radio Servicing, second edition https://archive.org/details/in.ernet.dli.2015.40748 (https://archive.org/details/in.ernet.dli.2015.40748) so I have a better idea of how you do the alignment on this stuff.)

I just ordered a few ESP32 modules from eBay for less than EUR 6 for my WiFi ePaper project (https://hackaday.io/project/20466-wifi-epaper). The old ESP8266 module is at its limits with about 40 kB usable RAM for this display, and I'm thinking about using a bigger display. The ESP32 module has 520 kB RAM and a powerful CPU, enough to run FreeType on it to render TrueType fonts on the system itself, and maybe even something like Cairo (https://en.wikipedia.org/wiki/Cairo_(graphics)), which would allow interesting new applications for it.

Been a few days already, but M3D mini 3D printer.

Really liked the compact and hyper light design and the internal spool, and the cheap price for a ready to use printer made me jump in.
I've had a K8200 for 3 years but was never happy with it, hugely bulky and would need so many upgrades to actually give a decent result that I've given up on it and decided 6 months ago to replace it with the Robo R2... but that's a kickstarter, and it's of course been delayed from the original January target. Came across the $250 M3D 2 weeks ago, actually available to ship same day so I took the plunge knowing it would still be a nice to have supplement once the R2 comes to print 2 things at a time or to carry around since it's just 1kg and literally fits in a bag (18x18x18cm - could actually be printed in one piece inside the Robo / K8200 /other 20x20 printer :P)

No need to say that everything I've printed so far has been WAY better out of the box than anything I ever got out of the K8200 despite the countless tweaking hours. Very neat little machine, super happy.

DPS5015 PSU module and an aluminum case.
I'll add banana connectors and a Dell laptop power jack to the input side. Output will have banana only.
I'll also test a battery pack inside the case. A switch can connect the battery pack to the input or output.
When the battery pack is connected to the input it is a portable PSU.
When connected to the output you can charge the battery pack with the PSU charging function.

Ordered from the states. I took one of the "cosmetic defect" units (and couldn't really find the defect...), so my white one that normally comes at a $25 premium  ($325) only cost me $249. With 3 filament spools and some spare buildtak sheets that came to $400 shipped.

It works so well I've been eating through filament a bit faster than expected (and it turns out you do need to replace those print sheets fairly often) so I'll have to place an order again...

Bought a 12V/10A brick power supply from eBay. Something rattled inside so I had to open it! Inside I found something funny, a second IEC connector. The output side is similar, the original wires chopped off and new ones soldered to the underside (almost shorted!). I guess the power supply is refurbished from something else. The caps are Rubycons though!  ;D

What would you connect it to? The casing is completely made of plastic and the original PSU obviously isn't earth referenced.

It's a PCB mounted socket (otherwise why would they have needed to add the second socket at all?), so it does have wires. That could be just some random bridge.

The earth pin of the outer connector is indeed not connected to the inner brick. The metal casing of the brick is earthed, and a quick continuity test from the output ground to mains earth shows a connection. I haven't tested it for noise but the output voltage is stable from 0 to 7 A. I don't know how the missing earth connection will affect the circuit but I'll connect it when I replace the connectors.

I got a 1T 10% resistor from ebay.  It checks out on the GR 1862B and the Keithley 610B, though with the latter, my measurement setup leaves a lot to be desired -- slow to settle down and if I get within a couple feet of it it upsets the reading significantly!

I ordered some time ago some serious HP "Iron" in an old 8662A - she is a very heavy unit with a plastic power switch down low and quite prominent , I needn't have worried - it was one of the best boxing for transport I have ever received.
Bubble wrapped, taped, foam peanuts with block polystyrene  around and then double boxed with more polystyrene and peanuts in between the boxes!
Amazing job from "e-liquidators" eBay seller  :-+. (no - association other than happy customer)
Here she is with about half the peanuts removed.

Nice packing job they did.  I wish all vendors would care as much.   Amazon is notorious for not giving a damn.  I ordered a ARB on board air compressor for $500 bucks from them a couple of years ago and they sent it in the retail box.  No packing, no nothing. Not even tape on it and this thing was around 30lbs.     The box arrived, and nothing else.  They sent another, and it arrived with a ripped up box and no wiring, papers, or any thing else.   So, they sent another and it arrived smashed.  Then I complained loud enough that they finally put it in a shipping box and it arrived fine.    $1500 dollars of destroyed waste.    Go figure.

First make sure it is fully isolated and modify it if it isn't.  Then use it for the occasional repair of computer power supplies, and anything else that I like to repair.  I have 4 shelf tube type AM radios that I inherited that act rather funky and I would like to get them working decently.  There is also a old tube hi-fi (cabinet type) that my father in law is giving me. It is in beautiful shape and I would like to make sure it works well, sell it, and give him the proceeds.  He's well retired and needs the money  more than we do.  IF I have to do any diagnostics on those units with power applied, it will be worth it as long as I remember to keep one hand in my pocket.  I can't afford a differential probe right now so it is the best I can do.

Haven't worked on a tube set in decades but I'm reading and brushing up on it.

I bought some dead batteries from 1986 or earlier (that's when Energizer was no longer owned by Union Carbide).  No leaks! Also a Simpson 255 that they were inside of -- may need slight calibration and exterior cleaning but is otherwise fine.

Title: Re: What did you buy today? Post your latest purchase!
Post by: Housedad on April 22, 2017, 05:59:45 pm
I drool for a Simpson meter.   Nice find and thank God those batteries did not leak.    Before those Energizers, almost everyone's batteries ended up leaking if left to discharge, both carbon and alkaline types.  Newer electrolytes and superior seals put Energizers on the map. In the 60's, 70's, and 80's, Radio Shack used to give customers a card for the "battery of the month club" that you could get punched each month and get free the crappiest carbon battery they could make.  I swear I think they gave them away knowing that the batteries would leak quickly and destroy whatever they were in and the customer would have to come back and buy another.   

Again, NICE find on the meter.

Cost me $20 because it's a 255 instead of the 260 that everyone knows.  For my purposes it lacks the higher DC current range, but otherwise is just as good.

Post by: Housedad on April 26, 2017, 02:31:53 pm
The medical aspect of the isolator is in the coil itself and that the housing and outlets meet requirements for devices in patient rooms.  The medical coil has additional isolation for capacitance and resistance to reduce leakage currents to levels specified by the NEC for medical grade devices. Not a huge difference, but still a difference.  The only advantage that I can see for us using a medical grade on our bench is that the units are usually of high quality in excellent condition, and hospitals routinely upgrade, putting all their old equipment on the market at affordable prices.

4030 Chinese CNC with 1.5kW spindle and 4th axis.

Been wanting to get into this for years, now is the time :)

VERY envious.
You must post up some pics and video.

Was it expensive?

That looks like a nice CNC machine.

I see some similar models advertised on ebay as being 4 axis and was wondering how that would work. Does it allow you to go back in time to fix mistakes?

Post by: plazma on April 28, 2017, 04:33:00 pm
It's axis. Not dimensions. Normally there are x, y and z axis. You can also add rotating holders (more axis) so you can machine more complex parts.

Just bought a manual from Artek (the scans I found freely available are horrible) for the HP 3312A function generator.  I got it recently cheap in not-quite-working condition because I wanted something I can use for sweeping old radio IFs.  I decided to avoid an antique electromechanically (60hz) swept signal generator :)
Although I suspect that most of the problem is dirty switches.


My HP 8644B is a wonderful signal generator but sucks for sweeping typical IF bandwidths.  (Slow, and the phase-continuous sweep ranges are too narrow in some cases.  The phase-discontinuous sweeping is useless with the typical XY scope setup.)

Hah. Here's a 4th axis:

$1500 shipping included... so definitely no.

Chose that one because:
- It's a 4030 with 1500W spindle, pretty rare - normally you've got to go to 6040 to have the big spindle, the standard for 4030s is 800W. Wanted the big one to have some margin and be able to do metal machining and have torque at low speeds for larger mills, but 6040 is way too big for my already overcrowded place and I wouldn't envision much use for the extra area for my stuff.
- It's USB, had no will to fiddle with finding the right PC/OS combo to drive a parallel port
- It's got a (supposedly waterproof...) closed circuit cooling/lubrication cycle and a 6cm tall removeable "skirt" (not pictured) that encloses the bed somewhat and should hopefully help control the mess a bit.

Drawbacks so far:
- Got instructions for the parallel port version, had to figure out how to get the communication working. Wasn't too complicated to get the basics working but I'm still missing the secondary IOs (end point switches, tool probe, emergency stop button). Messaged the seller to get data and will see if I get a response before I start delving into it.
- USB boards apparently have limited IOs so the end point switches of all axes are ORed together. Not sure if it's really a drawback - they don't actually matter that much in the first place, you've got to check your ranges are free of holders and stuff anyway.
- Spindle is manual control only. From the very quick look I had in the control box it's likely that computer control can be added with just a bit of wiring.
- Can't get my hand controller (purchased separately elsewhere) to work yet

Used a Dremel 3mm mill for the "Test", all I could find in a shop on the spot (machine arrived so quickly my sets of mills aren't there yet  :scared: ). There were a few engraving V-tips with the machine so the PCB is done with that.

Anyway an actual something in an afternoon is pretty satisfying already  :-+

Ha ha, yeah.  Blasted the piss out of the switches with isopropanol spray and worked them a lot and it seems to be working great.  Only really need to fix up the SYM CAL switch which seems to get stuck no matter what.

dexters_lab obviously subscribes to the "bait" theory of equipment acquisition, as do I.  In brief, if you want something but can't find it, start collecting all of the parts, documents, etc. that you will need to repair and/or operate it.  Now, somewhere out there, there is a broken electron microscope that "knows" that dexters_lab has the parts to fix it.  It will find its way to him.

That's a good one, and often true, oddly enough. I'll add it to the TEA Glossary (https://www.eevblog.com/forum/chat/test-equipment-anonymous-(tea)-group-therapy-thread/).

It wouldn't have happened if you hadn't laid out the chum line.  Also, in two months, when you're using it and the unobtainium component fails, you will have a spare and the document on how to replace it.

Not to mention the fact, that if you ever do get it working, you'll have at least 8 spares for 90% of the parts, that you were forced to buy to get some hard to find parts.

I gave up doing that years ago. It's always cheaper to wait for a complete device.

I got a RPLIDAR from seeeeeeeeeeeeeeeeeeeeeeeeeeeeeedstudio or whatever it's called (well, actually 2 because their 2 price is way better than the 1 price and I can sell one on..)

Here you can see it trying to make sense of my extremely messy office... 180-240 deg is the corner of the room with the door. 240-300 is my ridiculously messy workbench with a collection of crap on it... 300-0 is blocked by packaging from the LIDAR sitting on my laptop, and a rack full of stuff at a really oblique angle. 0-30 is the wall behind my computer desk... 30-120 is a whole pile of crap on my computer desk, and an open cupboard... And 120-180 is me. It tracks my body movement quite well, and I can see each of my arms when I lift them up through its plane of vision. Looks like it'll be very useful for a movement tracking idea I have.

And a photo of it on the desk..


Also from the photo you can see I bought a bus pirate 3.6 while I was at it.

And I got my CY8CKIT-059 from Element14 too..

Amongst lots of other foodies I've bought over the last few months, I just paid for a nice looking EDC AC voltage standard. 6 decades, 10mv, 100mv, 1v and 1000v ranges. I've got a few EDC DC voltage standards, so I'm looking forward to getting this one into the rack.

The model is AC1000DB, but I couldn't find much info on them when I had a quick google at lunch time.

Other goodies I've recently purchased are some Leeds and northrup resistors, ESI SR1 resistors, and a kikusui Insulation Tester.

i am kinda the other way around... i know there are parts in it that can be used elsewhere and i'll get to make a teardown video while we're taking it to bits

the real kicker is the company i got it from scrapped the other half, which was the control & display console before they realised it went with the actual microscope  :palm:

Random eBay purchase arrived today. The description was pretty meaningless and from the photos it was obviously home-made (or at least an one-off custom job) but it also has a calibration tag and the seller regularly sells surplus college lab equipment. It was cheap enough, so I let my curiosity get the better of me.
So when I got it out it greeted me with a worrying rattling.

Opened it and found what you see attached. A Maplin GA28F MOSFET amp (seems to be a a later one, judging by the use of Exicons an a power supply that looks to be a rushed replacement. I don't think anyone though long about it, the way it was mounted.

Still no idea what it was actually used for.

Unfortunately it's still in LIF format, so not easy to copy. It's on the list to get an old DOS box up and running, as I also need to copy and archive a bunch of HP 70000 LIF disks I have kicking around.

I will guess it was meant to be a servo amplifier, used to drive some laboratory experiment. Mosfet output gives reasonable performance ( at least somewhat in the sink side, not so much on the source side) with 22V rails, and was probably used to drive some loads like transducers and such that needed a little more grunt than a 741 could give.

Real brass, or plates steel which is a lot more likely in cheap hinges.  Nylon hinges likely used as they are cheap, and a drop in part for the older types of recessed hinges.

My Keithley 2700 from TheSteve just showed up!

I'm very happy to have a good workhorse meter with decent resolution of my very own.

I can't recommend TheSteve highly enough for his part in the purchase. very easy to deal with and a great guy.

OK, Found two tantulum 22uF 25V capacitors that smoked like a cigarette burning.

Old tantalum caps will do all sorts of "fun" things.  I restore "vintage" computers.  I've seen them explode like firecrackers, leaving nothing but minuscule lengths of their leads sticking out of the circuit board.  I also once watched in fascination while one put on a show like a miniature volcano, finishing by blowing little smoke rings.

The old tantalum manganese dioxide caps where well known for their spectacular failure modes, many a device has been destroyed by a failed tantalum! Just think back to hire much fun burning magnesium was in high school and it's easy to appreciate why putting manganese dioxide in a cap was such a bad idea.

The new tantalum polymer caps solved those problems tho and made tantalum caps as safe as aluminum polymer caps.

Couple days ago - a TM501 w/PG501 pulse generator. Needs some work but we'll see what we will see. I also plan to post some screen shots from my scope from choice test points in the PG501 if I get it working. This for people to use in the future, in case they have a non-working unit. I am also going to do the same for the other repair item/thread still open - the FG501A.

Nice!  I've always thought of getting one of the 8000-series meters (more likely one with autoranging) because I love nice little bench meters that are easy to read, but truth be told, I have enough multimeters (7 working, one to fix at last count, I think.)

One can never have enough multimeters. This one will join a Fluke 87, 8021B, 8010A plus a Tek 2465 DMS w/DMM option and a Heath V-5 VTVM.  Oops...almost forgot....a Mastech MS8040 DMM too.

I bought one of these. It's a Purelink CSW300 HDMI transmitter/receiver, but it will most likely be going back in a few days. The product claims "up to 100m" transmission. Reality: It works up to 9m, at 11m with one brick wall it wasn't even able to pair with the trasnsmitter  :palm: Engineering need to talk more with marketing.

It is, but my test managed only 9m with line of sight! What planet were they on where they managed 100m? If it "only" managed 50m I would have been ok with that, but to not even manage 10% of their claim?

Picked up an Icom PW-1 1kW linear amplifier at a ham swap on the weekend. 1.8 - 54 MHz, 35 watts drive for 1000 watts out. It uses 8 MRF150 FETs. Just ran it through its paces into a dummy load and it is all good. First contact on the air was to Slovenia on 20 meters.

Also ran into Mr Carlson - he would have been more impressed if the linear was tube based :)

Was the best swap I've been too in quite some time - depending on what you're looking for of course. I didn't run across any Nixie tubes but did find some nice looking chassis mount K connectors, and many other quality connectors, even some low thermal EMF stuff. There were many deals on HF rigs which isn't too common.
I've had great weather many weekends so far this year, maybe it is sunnier in Langley :)
Mr Carlson was pretty funny, he was sitting behind a table working the crowd the entire time, no shortage of people wanting to say hi to him. I threatened a picture but he hid his face.

See https://www.amazon.co.uk/Bosch-PLL-Laser-Spirit-Level/dp/B000W3BOBO (https://www.amazon.co.uk/Bosch-PLL-Laser-Spirit-Level/dp/B000W3BOBO) for some details in English

You align it  as normal using a bubble and two lines but it projects a red laser beam out the pointed end that gives you a 5m long spirit level. This was an impulse buy but it makes things like cable trunking along a wall dead easy. Takes two AAA cells and comes with a steel plate that can be used to secure it to a wall using the built in magnet.

Bonus: The cats love chasing the beam along the floor

Price: About 20 Euro depending on where you buy it.

My latest purchase is a Picoscope DS2407B!

They don't get the love around here so much because they are a bit pricy compared to the many good performing desktop scopes available these days (Rigol, etc.), but last year I was looking for something I could throw in my laptop bag easily and didn't have to worry about hauling a desktop scope around.  I bought the 2 channel version of this one (DS2207B) last year because I figured two channels meant more portable, less probes, etc.  My theory was that it would shine mostly for its portability compared to a desktop scope, but I found that it is so easy to use I prefer to use it instead of my desktop scopes!  Given that and that I often would like a 3rd or 4th channel, I decided to pickup the 4 channel version.  One thing I like is that the bandwidth is much better than the 70 MHz specification.  I've measured 2ns rise/fall times on its channels.

BTW, the "color" coded channels are my addition with color laser printed stickers.  Pico should have done that from the factory though...

Well I didn't buy it but I am paying for it with a sore back...
Rescued from the Dumpster....
3KV power supply.....
As posted over on the QRZ Forums....

An acquaintance of Pat's (WA6MHZ) showed up at the Radio Hospital one day while I was there.
We engaged in some RF related conversation, really smart guy, he said the same about me Blush.....
He had this and was going to send it to E-Waste....

Supposedly this is a power supply from a transmitter built by Northern Radio Co.
I picked it up yesterday from the back of Pat's Flex..
I still feel it... That is one heavy sucker...

Yes I will check the bleeders before powering up...
Note the caps which are oil filled... Something is missing......
The socket is control and metering. There is something down in the lower right corner that makes me a bit nervous..... I wonder who's idea that was?

Reasonably nice iron, it is a choke input filter and the choke is in the negative side of the power supply.
You can see the metering circuits in the upper left hand corner.
The bride rectifier is hard to see in this photo but it is there.

You are right Sue, that bridge could do with around 5mm of ceramic thermal pad between it and the heatsink, or a 2mm hard anodised thermal pad, which will ithstand that voltage no problem.

Caps probably are PCB filled though, so do not drool too much on them.

I plan on pulling one and seeing if the numbers are behind the brackets.
I'll pull out the bridge and see what value they are if there are no numbers on the caps...
While I am at it I'll check the choke also.
I am not too thrilled with the AGC type fuse in the HV DC out...
If that fuse lets go it can explode from the high temperature arc.

That does look like a mighty heavy beast!!  I was wondering where the rectifiers were at first, too, til the later photo.  Is that a 7109 date code I see on the bridge?  It does look awfully small.   :o

And if the caps have PCBs, it'll still be ok to drool on them - just don't lick 'em!

I think that is the date code on the bridge. that makes it somewhere around the first few days in March.

As for PCBs As I remember they were banned in the us in 1972.
The caps would be okay as long as they are not sweating, and as long as any of the escaped oil was not heated. When PCBs become vapors they are especially dangerous, as bad as drinking them.

It's currently Hunchback from circa 1983.  The controls need some work and the general condition is a bit poor and rusty but it does appear to function.  It's a Z80 motherboard.

I don't think the table style video games were all that common, at least not in the area I lived. I only remember playing on one. It was sometime in the mid 80s and I don't recall the name of the club, but I'm certain it was some kind of tank vs tank game played from a top down view.

Not today, but I wanted to introduce my Dad to the wonderful world of Metcal/Thermaltronics so I got him some tips/handpiece/stand new and bought a couple old Metcal RFG-30 used (one as a backup for the one I already use myself) on eBay, since that part doesn't seem to get worn out at the same rate as the handpieces.  So far I've recapped the electrolytics in one (the ESR didn't seem that great, one was bulging too), and replaced the incandescent pilot light which is always dead with a resistor + orange LED.

As for the one I bought for myself, I think I am going to find one of the slow-fading rainbow LEDs I have around to use as the pilot light.

That is a recorder that records an HD video (+16 channels of audio) from an SDI* video bitstream.
I use it with my video switchers and 6-8 cameras for live event recording and live-streaming.

These things are very popular for "iso recorders" on big TV productions.  They run a recorder like this on each camera to capture everything in case the "live-switch" mix missed something or there was a better shot that the director didn't call.  They are also popular for "video-walls" where you have a big array of TV screens and a video recording created for each position in the array.  They are easily synced together with an ordinary 75 \$\Omega\$ BNC cable daisy-chained from one recorder to the next.  Then you can start-stop all the machines and play back the videos in perfect sync (with time-code embedded in the recordings).  They can be controlled over Ethernet, and can even be powered by PoE.

Just to be fair - it is not recording 6gbps to SD cards - it is seriously compressing that data into a MUCH smaller payload with a ProRes codec. Still an excellent box at a great price - just not defying the laws of physics quite yet.  :-+

Yes, of course. It offers the user's choice of these codecs for compressing the video...

I remember BlackMagic from a few years ago when they introduced a m43 "film" camera for peanuts.. just went to their website, wow. It's amazing how much stuff they have now. In like 4-5 years it's amazing to see how far they've come. Their products are great for the price.

I am very lucky!  I had to buy it instantly, at that price.  That's not much of a problem, I don't think.  It might have been off of power for awhile, but that will just take some time to settle out.  I can cal it at my lab, once I feel it is sufficiently stable!

I tried to do 1/16 of the job today, and it is really exhausting, especially the tinning part of litz wires. So I ordered a tin pot, a solder bar and a bottle of liquid flux.

Why is the wire so expensive, pure quantity of copper? Hopefully can post pics when its done.

I finally found the 64MB SPI NOR Flash chip: S25FL512. Now my V3s board can have a full Linux installation without SD cards. (Only one of the two SDIO interfaces are connected to the microSD card, the other goes to an SDIO Wi-Fi interface)

Having to assemble a 1.7mH, 200A inductor assembly made of totally $4750 of toroidal magnetic cores and $1000 of litz wires.
I tried to do 1/16 of the job today, and it is really exhausting, especially the tinning part of litz wires. So I ordered a tin pot, a solder bar and a bottle of liquid flux.

Why is the wire so expensive, pure quantity of copper? Hopefully can post pics when its done.

No. Just typical litz wire, the only thing that makes it expensive is I need 1200ft of them, and by them, I mean 460 strands of AWG36 magnet wires bundled in a nylon sleeve.
There is also cost for insulation. My litz wire doesn't come with additional insulation, so I have to cover them with heat shrink tubing, which is very labor intensive and skill demanding.
Finally, to take high voltage, inductor core must be taped with hand cut Mylar strips and finished sub assemblies (I have 8 sub assemblies to form a large inductor) are held in place with double layer of 1/32'' rubber sheets, then cooling fans are installed.
So at the end of the day, it is nothing but a normal inductor, just this one costs $10k to build, which is not exactly expensive considering this is at the core of an 800kW converter.

That's some interesting gig you got there...

Bought a "360eye WIFI Wireless IP Camera 720P HD".

Ordered it on eBay for 18 Euro. Took over a month to arrive and it turns out to be a complete waste of time and money. A complete junk. Silly me, thinking a 18 Euro IP CAM would actually work:

1) It only connects to iPhone or Adroid phones. My mistake, should have read the description with more attention.
2) To set it up it will create a WIFI AP. Using this AP, no way you will connect from internet.
3) You can configure it to use your AP instead. No info on which port (5050 - found out through port scanner) to open on router for external access.
4) No control on network settings, ports, etc. All very obscure.
5) No power adapter included, requires USB 2A source - not easy to find, luckly I had one from Raspberry Pi.
6) Connection intermittent - after one successfull connection, it needs to be rebooted.
7) PC software works 1 out of 10 reboots.
8) SD Card reader fails to se SD card

This is the kind of device you feel like literally throwing out of the window. What a piece of junk! What a frustration, constrant reboots, no connection, then it connects, then it lags, then it doesn't connect anymore...

But, hey, 18 Euro - what the heck. The good purchses make up for it.

Cheers,
vma

Picked up a couple of 'some assembly required' units.

First is an HP 6002A power supply.  50V, 10A, 200W with GPIB.  No output.  $40 plus shipping.

But wait!  When I look at the back.......

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=318978;image)

Those two grey switches on the right.  Not sure about the one on the right, but the one on the left sure looks like it's pushed in.  No!  Seriously?

Second unit is an HP 5065A Rubidium Standard.  Top & bottom covers missing.  Some companies do this to 'destroy' equipment before they dispose of it.   >:(  Boo!  Hiss!   :box:  Kill all the lawyers - and bean counters!!   :rant:

In the world of Rb Standards, these things are the gold standard.  A few weeks ago, one sold untested for $1500.  I got this one for $123.   :wtf:  :-+

Lots of fun coming up!

Does the 5065A work? I have top and bottom covers that would likely fit, not sure I'm ready to part with them yet though.
edit - well they looks like they would fit but they don't have the required vent holes, so never mind...

Oh, right!  Dangle them in front of me and then snatch them away!  Thanks a bunch, Steve!  ;)  :-DD

I don't know if it works or not - it's still on the way.  I'll be a bit surprised if it does work right away.  In the pictures, I see a few missing screws on the bottom and a couple of disconnected wires.  I also noticed what looks like a misconfigured thumbwheel switch on the module that's missing the screws and the wires so, who knows?  Wouldn't that be a hoot!  Throwing out a gem like a 5065A because of a thumbwheel switch setting!

That's half the fun with this stuff!

But then they equip it with rackmount ears and don't say anything about allowing ventilation space above or below.  It draws between 49 and 72 watts depending on options.  There's no fan so cooling is strictly convection.   :-//

Well, for the first month or two I doubt that covers will be my biggest concern.   :)

Seems to be built to a schematic that Elektor published a few years back. Well made and was cheaper than making up the PCB myself. Ignore the 5-15V supply statement in the picture, it uses a 78L05A regulator which has a dropout voltage of 2V, so it actually works from 8V upwards. I intend bypassing the regulator completely and powering it directly from the USB ports of my scope/analyser.

A Terasic DE0-Standard FPGA board featuring Altera Intel FPGA SoC with dual core Cortex-A9 and 110k LE of fabric and a few 3.125G SERDES, though the board doesn't break out any SERDES pins, so effectively this is a board without SERDES.
Got the board for free from Terasic, in return I have to provide them a demo application with all code available under MIT license.

That's strange, Intel is using ARM cores?

Nice that you got it for free, what demo application do they want, and where can I apply? I guess a blinking LED is not enough? :)

A reel of Alpha-Fry 60/40 solder. Regretted immediately after received it. Doesn't work well with my flux pen, and doesn't work well on its own flux. I guess I will just keep using SAC305.

A bunch of these incandescent 7 segment displays, to finish my minitron-clock, and synchro differentials for experimenting.
A already received 6 of the displays a few weeks ago, one was bad (lower intensity and higher current than the others, maybe due to internal gas residues), and I broke one while starting to build the clock, so I ordered some more.

Picked up a couple of 'some assembly required' units.

First is an HP 6002A power supply.  50V, 10A, 200W with GPIB.  No output.  $40 plus shipping.

But wait!  When I look at the back.......

Those two grey switches on the right.  Not sure about the one on the right, but the one on the left sure looks like it's pushed in.  No!  Seriously?

Second unit is an HP 5065A Rubidium Standard.  Top & bottom covers missing.  Some companies do this to 'destroy' equipment before they dispose of it.   >:(  Boo!  Hiss!   :box:  Kill all the lawyers - and bean counters!!   :rant:

In the world of Rb Standards, these things are the gold standard.  A few weeks ago, one sold untested for $1500.  I got this one for $123.   :wtf:  :-+

Lots of fun coming up!

Ed

Well, that was wasn't nearly as much fun as I expected!

I repaired the power supply by plugging in the internal connector that came loose.   ::)

I repaired the Rb Standard by cleaning up the carnage from 5 or 6 leaky Tantalum capacitors and undoing the damage caused by the previous tech.   :palm:

This took 3 years to find. A General Radio 900-TUA tuner. Sister unit to a 900-TUB and 900-LB slotted line I have.
It's on its way, still has some international hurdles to pass. Hope I didn't jinx things by mentioning it before holding it in my hands.

Looks like it's missing the paper manual, so that's one more hunting item.

It's being shipped to me, but I just bought a B&K Precision 1511 power supply for super cheap.  :) 

Sadly, I didn't pay attention to the specs - only 10mA max output on the high voltage side, which limits its usefulness. At least the low voltage portion has decent power.

0-20VDC, 5A 0-80VDC, 10mA 0-500VDC, 10mA

Simple and to the point!

Operation:
Plug model 1511 into AC outlet. Turn power switch on.  Select desired voltage, use
control knobs to adjust output.

A reel of Alpha-Fry 60/40 solder. Regretted immediately after received it. Doesn't work well with my flux pen, and doesn't work well on its own flux. I guess I will just keep using SAC305.
Pad wetting performance is absolutely horrible (compared with MG Chemicals 4900 SAC305 I used before), even on gold pads.
The only reason I bought this one is because I need to solder some fairly heavy joints tinned with leaded solder pot, and I don't want to contaminate old solder with lead free solder.
I guess I will have to live with this, but hopefully after this project, I won't have to touch leaded solder anymore.
Don't want to derail the thread, but seriously, try Kester 44 (either 60/40 or 63/37). This stuff wets like nothing else. The flux is compatible with any rosin based flux pen (I use a Kester 186 pen when necessary, usually when drag soldering). I have several different solders on my bench, and the only reason I reach for anything else is because I don't want to 'waste' my Kester 44! PM me your address and I'll mail you a sample.

I've been using something similar for ages but without the arms etc, however it was only 2x and I found that not strong enough for SMD work. Then a mate showed me a nice much larger 5x unit on eBay for $42 shipped, so I just ordered it. Should make a huge difference.

TiN, that pile of PCBs on Volume 2 does look familiar.  ;D

For a decade or two, I have had a couple of the old, vintage Luxo lamps with the circular fluorescent lamp and the big 6 inch 150mm glass magnifying lens. From the Tektronix "Country Store" (surplus sales outlet). Pretty nice, but not portable at all.

But I just bought this gadget from Amazon.  Pretty nice.  I'm getting another one for my tool kit.

I got a Nicolet Sigma 30 oscilloscope.

That's a neat looking oscilloscope. Apparently those were made for high resolution measurements in physical and biological type applications. The fact that they made a version with "an enhanced magnetically shielded RF enclosure built to withstand extreme electrical and magnetic fields" may have something to do with the unusual placement of the inputs. I does kind of remind me of some kind of medical device.

I'd say you scored.  :-+

I don't see how it can work right with the spigots on the side.  :-//

Does the screen have a 3D view mode, with the traces arranged in perspective like they actually were coming from the BNCs?

I'd say so too.  ;D . It can do 100uV/div and the measurements and analysis menus smokes everything I've seen in previous scopes. Got it with new probes and only paid for a couple of ADCs  ^-^

I know what you mean. I had a decent Nikon stereo microscope, my father in law borrowed it a few years ago, and really liked it, and now I'm too embarrassed to ask for it back, besides I took his daughter, seems like a more than fair exchange... I guess I'll  look on eBay for a microscope...     ;)

Well, Keysight offers the really nice 6000X scopes for up to 6 GHz
I have the scope but unfortunately no 6 GHz probe

How much did you have to pay for the 7 GHz probe?

A 'universal' 100 watt power supply, as pictured below.  It has a bunch of selectable voltages, up to 24 volts.  I'm using it as an expedient way to power the 365nm UV LEDs in a UV exposure box I'm building.  I've stuck a 3D image of the box down there as well.

But I have to admit, I'm rethinking my whole approach to making PCBs after looking at what CNC machines can do.  Less fuss, less bother, much better results.  I've built a few 3D printers, so it should be relatively straightforward to throw a light duty CNC machine together.  Or just buy one; there are several on AliExpress around the $300 bracket.

That's really quite irrational. You should give some more attention to the causes of your response.
Here's an image to help with that. An assortment of surgical and dental implements, a large proportion of which were from hard-working environments.
Their history would have included countless cycles of use then sterilization. Followed by lying in damp, mildewed and rotting old boxes in an abandoned basement for maybe two decades before recovery.

But they are high quality stainless steel, and so there is nothing wrong with them at all.

Like small pliers they can be used for a multitude of things:
Hot handling.
General small plier duties.
Small fishing hook removal.
Holding needles firmly when stitching something tough together.

Here if the complete manual:

Immediately after use: Wash the equipment with soap, rinse the equipment under running water until clean. Do not reuse for the day.
At the end of the day: Boil the used equipment in water using a pressure cooker at 105 degrees Celsius for one hour. Allow the equipment to cool during the night wrapped in a few layers of clean tissue paper. (In hospital they used sterilized cloth for this, tissue paper is a good home replacement.) The tissue paper should be disposed of after use.
The second day: Submerge the boiled equipment in a strong bleach entirely for 24 hours.
The third day: Rinse the bleach off the equipment using distilled water. Store in a box covered in tissue paper. (ditto for the sterilized cloth above)
Immediately before use: Dip the end of the tool to be used in 75% ethanol.

Locking hemostats, my favourite tool.  :)
Never seen so many.  :scared:
wondering in what capacity do you use locking hemostats for in electronic applications? I have some, but rarely use 'em, occasionally as a heatsink for soldering a sensitive TH part.

Mine mostly get used for plugging in replacement sensor boards on equipment I service.  My fingers can't get in the space where the cable is, so I hold the wires just behind the connector and reach in the limited space to plug the board up.  No, I don't squeeze tightly, I don't want to go through the annoying process of replacing the cable due to damaged wires.

After trying in vain to solder some wires on a car outside on a windy day with my Portasol Gas Iron I decided it's time to try some other solutions. All of my other irons have bulky stations connected to them and are wired down behind my bench, making them difficult to move. I've read and watched some reviews about this iron and it seems to be more than just a gadget. We'll see when it arrives...

My family still sterilize our cutlery once every two or three months. The same boil-bleach cycle. We are even adding a little of vinegar into the bleach to make it stronger.

The cutlery in my family is mostly made of stainless steel and tempered glass, so they can withstand the hot and then highly oxidizing/slightly corrosive environment.

I live in a much larger world than just electronics......believe it or not.  ;)

Like small pliers they can be used for a multitude of things:
Hot handling.
General small plier duties.
Small fishing hook removal.
Holding needles firmly when stitching something tough together.
And so on.

I see. ;)

Title: Fujitsu FCT344AU NiMH Charger
Post by: rdl on June 14, 2017, 09:19:23 pm
My Maha C808M has apparently decided to take itself out of service (and a couple of batteries with it in the process). Until I can see if it's fixable, I ordered a couple of new chargers and I figured I might as well get some batteries at the same time. The first purchase arrived today, only $22 from Newegg with 4 low self discharge NiMH AAs and shipping included. Took two whole days to get here.

The bleach used in my house is based on sodium perchlorate. The added acetic acid promotes the production of perchlorate acid molecules, which is highly oxidative and cuts through bacteria easily.

Seriously the CSSD (central sterilisation supply dept) of all hospitals surgeries etc has serious cleaning and sterilisation protocols including proof of attainment of correct time at temperature. Auditing and accreditation are undertaken at regular intervals.
I could not replicate this at home.
Re cutlery there is good evidence that cleaning with hot soapy water and drying is adequate.
Probably the biggest issue is a lot of people don't wash their hands - figures re public toilets are around only 30% wash.
Also remember that there is increasing evidence that a bit of dirt is good!

Then I would also not think about the fact that sterility with 100% certainty does not exist. Typically, we prove a high SAL (sterility assurance level) of 10-6 (1 chance/million something remains non sterile), but if you are paranoid, there is still a remaining chance...

There are bacteria that will happily live in 130C water ( under pressure) at the bottom of the ocean, and others that are quite comfortable at sub zero temperatures all the time, and if you look at the assorted Tardigrades, that can survive being frozen, boiled, irradiated with enough radiation to kill all other life, exposed to vacuum for years in space, and come back to life, even after you have taken them, dried them out, stuck them down with a drop of superglue to a metal plate, sputtered a gold contrast coat onto them and then placed in a SEM to image them at high resolution.

The ant almost made it all the way through, it at least was still trying to break free when the gold sputtering was applied, as evidenced by the cracks in the coat in scanning.

The second charger I ordered arrived yesterday. This one is a bit more capable than the Fujitsu I posted previously. The Fujitsu appears to work fine except sometimes seems to get confused when older batteries are loaded. Note how this one advertises "Fire Retardant Materials" and "Worldwide Insurance". Inspires confidence, does it not?

What have arrived in the mail is two entirely different categories of items: microcontrollers, and games. Those are all just chips though...

The microcontrollers are the STC 8051-compatible ones from three different lines: the STC90C516RD+ (a 12T/6T core,) STC12C5A62S2 (a 1T core with AT89C51 pinout) and STC8A8K64S4A12 (a 1T core with a different pinout, prerelease chip.)

The games are Pokemon X (middle) and Pokemon White Version 2 (right,) both Japanese region copies. I imported these games (and the console) since those games never saw a native release. The game on the left is Pokemon Sun which I have cleared back in February.

Nice, a Yamaha NP-32. I have a Yamaha P-85. Maybe buy your son a sustain foot pedal, too, they are cheap but very useful.

I guess the USB port uses a standard MIDI protocol? Then you could use a piano synthesizer on PC or laptop, which makes it sound like a real grand piano. I can recommend Pianoteq (https://www.pianoteq.com) (they have a free trial), with which I have played this:

Your playing is vastly superior to mine but the patches sound a bit off to me, I can't quite place my finger on it but it just sounds "electronic", but not in a good way. I really should dust off my M-Audio Axiom 25 and hook it up to my Roland MT-32 again (it's piano is rubbish too but LAS synth is amazing fun in general).

Thanks. The video is 7 years old, I think Pianoteq was very new back then, maybe it is better now, or maybe I tweaked too many parameters :) I remember turning down the noise of the sustain pedal, which is synthesized as well, and other parameters.

I think the best piano sound, besides using a real grand piano, are generated by Kurzweil pianos. IIRC they use a combination of lots of real samples and synthesis.

It's amazing  to me that piano is still one of the most difficult instruments to synthesize well even after more than 30 years of effort.

I bought a piano sample library in 2008 or so, it was 80GB for 4 piano's and sounded amazing although the hardware was the limitation. This should now with more cores not be a problem anymore.
The HW only piano I am still interested in but I don't want to spent that money is the Roland V-piano, that is a synthesis only machine that sounded really good.
But a real grand piano can for a real pianist never be replaced too many variables if only that two speakers can never replace 100s of strings.

I've had trouble cutting PCB material with a band saw.  They work great on the old phenolic board.
The FR4 is very harsh and with a fresh band-saw blade I've actually seen piles of sparks flowing out under the board as it is cut.

A band saw is very handy for all sorts of other jobs especially if you can drop the speed low enough to cut ally.


One day I'd like to buy one of those small combination bender / roller / guillotine machines for cutting boards.

I just wish the Tektronix 575 curve tracer was in the lot to go with the 175

I had an issue recently where I needed to check the earth leakage current on piece of machinery that the leakage supposedly started to increase the longer it operated, whilst google searching I saw a recommendation for a Chauvin Arnoux C173 current clamp that had switchable ranges from 1000A down to 1A with 1mA resolution on the lowest range. I thought Ok that with my scopemeter would be perfect to log the trend over time. A quick ebay search for a C173 found nothing but knowing AEMC are Chauvin Arnoux in disguise I had a look at their offerings and saw the SR759 was the same thing. I found a seller offering one in the US and got it for the opening bid $89, with ebay Global shipping it was all up $170 aus dollars so I'm pretty happy, this photo is the sellers photo and whilst the box is a bit tatty the clamp has never been used.
It arrived to day and it looks exactly the same as the sellers photo, it has never been used, I checked it out on a piece of equipment that I had tested last week with a borrowed Hioki 3283 and it is giving the same readings so it seems to be still in spec as well.

PSoC is a piece of shit without proprietary IDE. You need the IDE and hence Windows.
KitProg connects to main board with not only the 5 pins. There are hidden traces for UART. Breaking off the board you will lose the UART.
I have noticed that and it is damn annoying. I have grabbed an evaluation copy of Windows 10 and thrown it into an instance of VirtualBox.

Yeah.  Re cutting PCBs with a bandsaw:

You're right.

I think I could have got a cleaner cut if I'd got a rabid beaver high on crystal meth, stuck my finger up his ass and let him gnaw away at the PCB.  Jesus.  Forget about a clean cut; it looked like the results of a fragmentary grenade.

So, I figured I'd return the saw.  But I'd thrown away some of the packaging, so I gave Canadian Tire a quick call to determine if it would be a problem.

"Yeah, I need to return a band saw..."

"Complete, sealed, never been opened?" she cut me off.

"Uhh, well, I did actually open it -"

"Sorry, no returns once the package is opened.  ThankYouForCallingCanadianTireGoodbye!"  Click.

So, that's the return policy at Canadian Tire.  Essentially, they don't have one.

So, I own a bandsaw.

Which acts like a rabid beaver, high on crystal meth.

Sigh.  I have to go wash my finger now.

The type of blade you are using will have a major effect on the results. What's the TPI of the blade you're using at the moment? There are carbon blades with up to 24TPI which should give better results. I'd try one of those (after you've washed your finger) before I gave up on the saw completely.

Brilliant!

The most expensive single component I have ever purchased - a Vishay VHP101 10K 0.005% resistor.

I've purchased one or two FPGAs that come out more expensive that that, but barely.

Does that resistor really have a ZERO TC?  Can you check it over temperature with your VM?  That property is what is being paid for, not the 0.005%.  You can play with pairs of resistors until you find a combination that is 0.005% within 10K without a problem, the issue is that with cheap resistors it will no longer be there once the temperature changes a few degrees.  That TC is the amazing part.

The TC is not really 0 - but it it should be quite low. I believe the resistors are made from different substrates/compounds in series. One increases resistance with temperature, the other decreases with temperature. The idea being they cancel each other out.
I haven't done any extensive testing yet. I need to mount it in a box with low EMF binding posts etc. Then some crude testing can begin.
I have always wanted one, my (terrible) justification was that I was already ordering from Digikey and needed to spend more money to get free overnight shipping. So in my mind I saved 8 bucks on the price of the resistor, lol.

Hey, DTJ, McBryce - you were right.  Sigh.  Perhaps I will find other uses for the bandsaw.  Or it might just wind up as another tool in my tool museum, right beside my squid stretcher and my female polar bear mounter.   The last might seem a bit odd, but let me tell you: if you ever need to mount a female polar bear, you'd damn well better have the right tool.

Gary M - you know, I keep hearing from everyone that PCBs are so cheap now.  But the cheapest I've found - for a 2.5 X 3.8 inch board with silk screen and solder mask is $61 USD - about $82 CAD + shipping, which will probably bring it up to around $100.  They do 3 boards for that price, but I don't think I need 3 boards.  I just need one board.  So I'm effectively paying $100 for a tiny little board.

I dunno.  It is true that I must have taken a vow of poverty in my youth, which accounts for my living under a bridge.  (But it's a very nice bridge).  But $100 doesn't seem cheap to me.  If you know of a cheaper way to get boards, please let me know.

Hey, Bendba - one of the joys of this saw is that it takes a 62 inch X 1/4 inch blade, which is a very unusual size.  I did find a listing on Amazon.ca for 5 diamond blades for about $248 CAD with shipping.  But I don't want to gamble that much.  I can also get a 24 tooth blade for about $31 with shipping, which still strikes me as pricey.

Hey, Djos, thanks for the shout out.  Don't worry too much about women not enjoying my humor;  they've never enjoyed it when I've inflicted it on them in person, either.  One young lady even got a court order, prohibiting me from calling her.  The judge looked at her and said, "Is he making threats?"

"No," she replied.  "He's telling jokes."

The judge looked at me.  "Tell me a joke."

"Well," I said, "Two gay judges walk into a bar..."

"I've heard enough.  The order is granted."  Bang went the gavel.

So, you know.  There's a ton of women, and at least one gay judge, that don't like my humor.

Hey, BU508A - I really like the look of that saw.  They don't have a sales rep in Canada; the nearest one is North Carolina, which is roughly 4,000 miles away.  I did a search on Amazon, and couldn't find anything similar; same with lee valley tools.  I'll keep looking.

Hey, Gyro - I think this one, available locally (from a store with an actual return policy) might be similar to what you're using:

https://www.princessauto.com/en/detail/7-in-portable-wet-cutting-tile-saw-with-3-bonus-blades/A-p8237489e (https://www.princessauto.com/en/detail/7-in-portable-wet-cutting-tile-saw-with-3-bonus-blades/A-p8237489e)

It's even on sale.  $70 CAD, with 3 diamond blades.

The one question I have - how do you keep the work space dry?  Or do you not use the water at all?

Thanks everyone, for all your great comments and suggestions.  I really appreciate it.

Best, Charlie

How wide is the blade slot in the table insert ?
For minimising underside breakout you want the slot in the insert to be as narrow as possible....maybe make a better one up out of some ply or acrylic sheet ?

Hi, tautech - yeah, it occurred to me that I could slide a sacrificial board under the pcb, and let it splinter instead of the pcb.  I think that might help.  But truthfully, I think that the bandsaw was a bad idea to begin with.  I need to find a better solution.  Still, I do think that a narrower blade gap would help minimize breakout.  Thanks - Charlie

As always, you folks are an incredible source of knowledge and wisdom.  I genuinely appreciate the help.

Blueskull, thank you for the offer!  That's wild, that someone on the board would live exactly there.  I'm still hurting from having spent $150 on a saw I won't be using, so I don't think I'm going to buy anything new.  Instead, I think I'm going to work at using the tools I already have.  But i appreciate the offer, and if my circumstances change, I'll drop you a line.  Thanks again.

MatthewEverett, cleaningOut - I'll check out pcbshopper and dirtypcbs.  After spending all this cash and effort on equipment and supplies to make pcbs, if it turns out that I can buy them just as cheaply...  well, sigh.

The blade gap on the bandsaw is large, around a quarter inch.  But... hey!  I own a 3D printer!  Exactly the kind of job it's really good at doing.

Something else I'm thinking about is making a guide to fit on the base of the dremel workstation, putting a milling bit in the dremel and using that to cut pcbs.  I would think it should yield a decent cut.  Another project for the 3D printer.

So last Thursday I visited a couple friends of mine on their acreage.  They're both getting on in age, he's had a heart attack and a quad bypass, and now uses a walker for anything outside their home.  So they want to sell the acreage and buy a condo in Victoria, B.C. where they'll live out the remainder of their lives.

So, they're in 'dispose of all this junk' mode.  His wife had a hewlett packard 2000 series laptop and an officejet 8500A multi-function printer, wasn't using them...

They drove home in my back seat.

The laptop isn't anything special; core i3 architecture from several years ago, 500Gb drive, 4Gb ram, 15" screen.  But it's a good 'surf the web' machine, and having an extra computer available never hurt anyone.

Similarly, the officejet 8500A wouldn't be my choice of printers; I hate inkjets.  And, the power brick that runs it had somehow gone missing.  But it does have a scanner/copier function with an automatic document feeder, it will print on both sides of a sheet of paper, and it connects via wifi.  So I found a cheap Chinese power supply on Amazon, complete with the funky HP patented plug.  While I was there, I ordered some ink cartridges.  The power supply showed up yesterday, the ink today... and after a ridiculous amount of ink spent cleaning the heads, it's up and working.  Got the latest firmware installed on it, so hopefully it will behave itself.

The officejet might prove useful in making transparencies for making pcbs; people complain that the laser printers put out too thin an image, that the blacks are grey rather than black.  Possibly the inkjet will do a better job.

Oh, and the other thing I purchased was a Wen rotary tool kit.  Got the tool, a flexible extension, a bunch of missc. bits and fittings, all in a tidy black plastic case... cost me a grand total of $28.  At that price, heck.  You can't have too many rotary tools.

Take care, all - Charlie

google prayer counter & see for yourself.  :o  seriously they used for that! 

cheap electronic event counters are going to go to sleep in just 12 minutes.
with a blank lcd screen. however its the dead count that is needed to wake it up.
so if the counter is 101 when it gos to sleep. it will sill be 101, when its wake it up. not 102,
even though the count button was pressed, making this event counters not suitable for count cycle lengths greater 10 minutes between counts. also with disassembly the lcd screen module with its conductive rubber strip will separate from the pcb without the case to hold it in place.
so if your considering hacking this cheap event counters take note.

It finally arrived, from Ukraine.
Two "new old stock" (indeed new, the plastic was still sealed) 30W pulsed IR diodes. Tested and with original datasheet, with matching number.

Datasheet says they are minimum 30W light output at a 40° cone. And then, test data says one tested 133.3W and the other 96.1W. Sweet!

Just gotta work out a driver and how to colimate and then focus them. And see what that can engrave/cut

Edit:

If I translated it right, it takes 100+-30 ns pulses at max 8 to 11A and max 500+-50Hz
I guess I'm not driving it with a pair of coin cells and a small resistor  :-DD

Post by: Bendba on June 28, 2017, 04:45:55 am
No, they are not for high average power (that would be too good, for $20
Maximum duty cycle is 0.5%

I didn't really buy them for cutting or engraving, really, I just want to try to see what they are capable of.

I want to try to make a long distance line of sight data transceiver, just for the fun of it.

Laser diodes follow up.

Well, I've either been ripped off or I'm missing something.
I went to measure the village do voltage drop of the diodes, they both appear as a dead short, no voltage drop and no resistance on the ohm meter.

Any idea of what I'm missing? Or did I just received two duds? That'd be surprising, it's from a usually very good seller.

Swift keyboard to its finest.

High power LEDs and LDs can be damaged VERY easily by ESD. After decades of being non ideally stored, it's not that surprised to see them being killed.
Modern ones are more resilient, such as the one I showed in my video, but there's a 30 years technology gap.

Yes, that's what happens when you forget to check messages before sending them.

That's a bugger, I've been as careful as one could be while opening the package because I was expecting them to be sensitive to ESD's
They even had a piece of cardboard protecting the pins from being in contact with the plastic.

Is it likely that they were dead before arriving here? They were fairly well packaged in the factory container and the original little plastic had was still sealed.

Just to confirm, sounds stupid to ask but, semiconductors showing a dead short, it's unequivocally and irrevocably dead, isn't it?

Yeah, that's about a 9.3 on the WreckedEr scale.  My sympathies.  Hopefully the reseller will make good.  From your obvious knowledge of the product, it's difficult to imagine you did anything wrong.  So either they sent you dead units - their fault - or they packaged them improperly, so as to render them susceptible to damage during shipping.  Again, their fault.

Reminds me of my bandsaw purchase.  Spend a chunk of change, think you've got a real solution, and then - oops.  Hope yours is more returnable than my bandsaw was.

On the purchase end of things - an FM radio kit I ordered a couple of months ago showed up.  Think it was around $9 USD from banggood.  Digital display, chrome antenna - what's not to love?

The seller is sending me some new ones tomorrow, he is going to test them before sending this time.

That little radio looks like the $15 one at the Chinese shop down town. But you'll probably do a better job at soldering and mounting it

Oh, we can hope!  I buy these kits mostly to hone my soldering experience.  But I'm way, way down at the beginner level.  But... I guess we all start there.

Glad the retailer is shipping you two new units.  Hope things work out!

Russian laser diodes follow up:

The seller tested a few of his stock parts and they all measure the same. He then done some researches (in Russian) and it turns out that particular one has a current transformer integrated in the casing.
He sent me a link to a forum in Russian, still trying to work out through the translation.

Has anyone ever heard of that, a current transformer in a diode casing?

My concern is an unobtanium custom IC that's in the signal path.  It seems to be a part that gets zapped if too much power gets fed into the input.  I have one with a bad one; got a (hopefully) good replacement on a spare board but it hasn't made it to the front of the queue to find out.

i bit the nearly literal bullet and spent $100 (with $50 for shipping) on a nixie tube version of the HP 5340A, with what appears to be every bell and whistle available for it.                                                                                 

Congrats! I was wondering who snagged it.

You were watching it as well? I practically saw it go up and had to wait for a torturous couple of days to get funds available.

I thought I have a chance of getting a genuine 256GB card for $64 (comparison: a 200GB card on Amazon sells at $75, so as a used card, $64 for 256GB isn't ridiculously cheap at all).

time to try out the wire cutters on the fake SDcard.

Don't cut it up just yet. Try run a diagnose program on it and find out 1) how much capacity it really has and 2) how fast it really goes.

FWIW, I've bought a bunch of stuff regarding my bench that I haven't mentioned thus far. For example, I purchased a few pieces of bench gear (bench DMM + 3ch. PSU from ITT tech), as well as the latest Amscope Trinocular Microscope (i.e. 3.5 - 90X). And a couple of hand tools as well.

The older I get, it seems the less patience I have :palm:  Which PSU did you get?  I got the GPC-3020 and the GDM-8251A plus a GOS-6112 scope.  Did you buy early on when the prices were low a gear aplenty?  I got the PSU for $65 shipped and the meter and scope for about $90 shipped.

PSU = GPC-3020

They were cheap enough I couldn't pass on them; $59 shipped for the PSU, and $90 + $13.30 shipping for the DMM.  >:D

(Sorry to ask)

How do you like them? 

I have some questions.. Is the fan on the PSU noisy?

>PSU = GPC-3020
>Bench DMM = GDM-8251A

The price is really attractive..

I like the idea of a bench DMM because I like to just leave my DMM on while I'm doing electronics, and the need to keep remembering to turn it off when something else comes up is kind of annoying. (need to get a system going for using rechargeables without screwing them up.)

Also measuring very low resistances and being able to adjust the threshold for the continuity detector is an attractive feature.

I don't like that it seems that the GDM-8251A doesn't have a capacitance or inductance feature.

But it does allow 4 wire measurement (nice)

Yes, the fan is noisy on the 3020.  It doesn't bother me, however, i can always turn up the music.  Lots of other fans, including a ceiling fan so it is what i is.  I don't worry about the 8251A's lack of capacitance or inductance.  I have a Der Dee DE-5000 for that.  Part of what I ordered in is a set of cheap inexpensive Kelvin clips and banana jacks to make up a set of probes for 4 wire just to have them.  I may never use them but I will have them.  You won't forget to shut off the meter.  The display is very bright.  I notice anything left on at the end of the day when I turn off the office lights and the meter brightness absolutely stands out.  I haven't bothered to see if there is a brightness adjustment, I like it where it is at.

Well, this followed me home today. Got for free from the printer tech company I deal with, as they were going to throw it out as scrap. did not get the stand it was on, they were going to use that for the new printer the customer traded this old clunker in on. Probably works too, seeing as it still is full of ink and solvent as well.

Well, what is it? Some kind of production line label printer? What does the print head look like?
And I'm not complaining, but wrong thread? "Free". Maybe better in 'saved from the dump' thread?

My favorite coffee making method is very simple and cleanup is a breeze. It is the so called "French Press" method. It was invented by a company "Chambord" I think.. I was taught this by a former girlfriend who is now a successful restauranteur, many years ago. It involves a straight glass beaker with a mesh plunger and you end up with just two sublimely delicious cups of coffee that have a bit of chewy grit in them. And your grounds in the bottom of the beaker. Then you rinse it off. Done. The coffee is really good. As good or better than expresso and much less trouble. Also, no need to buy filters, ever. Just keep it clean. Definitely worth trying. The french presses are now mass produced and quite cheap. So no reason not to try it if you drink coffee.

This is the one I have.

https://www.bodum.com/us/en/1928-16us4 (https://www.bodum.com/us/en/1928-16us4)

There are cheaper ones which work just as well.

The parts are replaceable, so save them if you break the beaker. I am on my third one.

Don't know why it is so good, but they really make a spectacular cup of coffee.

Well, a couple of days ago anyway. A nice cheap ebay find, a 6 decade thumbwheel variable resistor assembly. Unboxed and in a rather nasty green front panel but with decent quality Contraves Swiss made switches. The main resistors are 2% metal film 0.5W, I've swapped the carbon film ones on the Megohm decade to 1% metal film too.

I've boxed it today and it's taken its place as 'big brother' to my tiny home made 3 decade substitution box (I think they look rather sweet together). Not the highest accuracy of course but handy for substitute and measure applications.

Well, it is an older continuous jet inkjet, designed for printing whatever is selected in the memory onto the substrate moving past under it. Either has an encoder giving line speed, or will simply have a preset width and assumes the line is moving. Will have a trigger input, some status outputs and such, but I have none of that, just the printer. Yes, probably does work, but as the cost of the consumables is not cheap, i likely will be parting it out.

Yes it will be messy, looking to go buy at least 20l of methylated spirits and a sacrificial roll of plastic to do this on, along with a whole big batch of newspapers to soak up the spills, plus wear old clothes and a lot of latex disposable gloves.

I am now the proud owner of an ultra cheap DS3231 precision RTC module purchased off of ebay.

If it is the genuine article its an incredible deal.

The chip is marked

DS3231SN
1030A3
24088  (or 240BB)

and the PCB is marked "DS3231 for Pi" I forget what I paid but it was under $2 with free shipping. It took a long time to get here.

Update: Out of two super cheap RTCs received, only one seems to work properly. Now I need to find some way of testing its accuracy faster. RTCs are strange in that they seem to only keep time to the integer second externally. Which complicates the matter of measuring the accuracy it seems to me. Not the best situation..

Now I'm about to Google and see if I can find an easy way to test it. Based on the price, it may be counterfeit or a "retread",. But, who knows. We'll see.

Smartphone holder for 1 EUR from China. See enclosed pic.
How on earth can they do this at this price which included shipping?
Anyway the spring inside is pretty stiff so that it holds the smartphone
really well. 8) :-+
And an adaptor 3/8-in. Whitworth 1/4-in (out of the studio junkbox)
to mount the smartphone on top of a common microphone stand.

And why I need it? To take many pics of stuff to be flogged on ebay.
Having the camera on a stand saves a lot of time and improves pic quality. :-+

My wife scored one of these from her work for me (she hates coffee, but luckily loves me. ;D ) - it produces amazing coffee and is very simple to use. French presses are easier but I found they went through a lot more coffee. The little Expresso machine has 2 different inserts depending on whether you are making 1 cup or 2 so you never use more coffee than you need.  8)

Ooww. How did that happen? Can you return them? If you don't use any analog video gear, you'd be better to have no 75 ohm leads at all. Getting them mixed is a perpetual pain.

I have a similar problem, only it didn't cost me anything. Boxes and boxes of very nice BNC patch leads, all lengths.  But they are from a shut-down TV studio, and all 75 ohm. My 50 ohm BNC lead stock is quite meager.

I wasn't paying attention,  they were cheap and they work for now. They were bought to make testing a frequency counter i bought (and am working on) easier, I'll get the proper ones at hamfest.
They were 2 bucks a cable and had i noticed before i got them i might have tried to return them.

Agilent 53147A - 20 GHz frequency counter, power meter and 50 volt DVM. I needed a power meter, figured it was a nice option as it also has the frequency counter. My signal gen only goes to 8.4 GHz.

Actually i believe in his case it is a DVM, meaning digital voltmeter. DMM implies it can measure voltage and ohms, perhaps but not always current as well.

Telecom industry I am sure - the DVM meter spec gives that away. There are three versions- 53147A, 53148A and 53149A - they are the same but max frequency counter spec is 20, 26.4 and 46 GHz respectively. They are of a very similar design to the 53150A, 53151A and 53152A frequency counters. They have the same counter ranges but don't have the dedicated power meter or DVM. The power meter is interesting in that it only supports the older HP/Agilent heads - mainly the 848x series. They can often be had for a great deal though. Mine came with a slew of very nice cables and adapters. It was clearly used by someone who worked on microwave gear as well as some cable TV services as there were also a few 75 ohm cables/adapters.

How much money do you have to spend roughly to make reliable good measurements on flashlights?
Sphere ?
Sensor?
Software?
What else?

Very nice! I wanted an integrating sphere for years while I was collecting flashlights. With the advent of high power LED's finding really bright flashlights isn't as tough as it once was.

The sphere was surprisingly affordable at $650 from lisungroup.com but freight and import costs pretty much double the price. If you get the CCD spectroradiometer with the sphere it's about $2000 extra. I use a spectrophotometer meant for display calibration and measurements, which is about $1000. You also need something to calibrate the numbers from the sphere, calibration lamp was $75.

Software is mostly free (ArgyllCMS, HCFR) or fairly cheap (Babelcolor CT&A). For illuminance measurements you need a lux meter, but my spectrophotometer has a lux measurement built in so I use that. The bottleneck of most cheap lux meters is the cheap color filters so their numbers depend on the spectrum of the light.

edit:
If you don't care for absolute numbers and just want to know how the output changes relative to time, there's this great Android app called ceilingbounce (https://github.com/zakwilson/ceilingbounce) to create runtimes graphs. It uses the ambient light sensor of the phone. Since the sensors are usually very linear, it works great.

For approximating color temperature, there's also several options for smartphones. I thought this (https://play.google.com/store/apps/details?id=cassiopeia.camera&hl=fi) was quite accurate (http://budgetlightforum.com/node/45051).

Well, on Sunday night (July 9th) I ordered a short 44 terminal extender card to use in troubleshooting my HP 5340A counter.  While searching on the 'bay, I also found two others that could prove useful, and ordered those as well.  I'm in Connecticut.  One shipped from California, one from Illinois, and one from just outside of Philadelphia, PA.  All are coming via USPS.  (Anyone care to guess where this is going?  ::) )

Two arrived in the mail today.  The ones from IL and CA.  The one I actually need is the one coming from Pennsylvania - geographically the closest origin point.  Its tracking info shows that it left Doylestown, PA and made it to Philly on the 11th.  And apparently disappeared into a black hole, as there have been no further progress updates.   |O |O

I should have known that the one from the far side of the country would make its 2500 mile journey in less time than the one that was only coming about 150 miles as the crow flies.   ???

Nevermind the crummy tracking, I just had a package from Hong Kong that showed up in Los Angeles, then went to Portland, Oregon before someone realized that the address was wrong. I live in San Diego, just 100 miles south of LA, and they had to send it ~950 miles north just so an actual person at a post office could look at it and go "Oh, that's not right."

Thankfully, someone did do that, and the package is now sitting in a post office about 5 miles away from my house, and will presumably be delivered tomorrow. That is, unless their computer system decides to send it out of state again.  :palm:

Edit: Or worse yet, they give up and send it back. I've had that happen before as well, albeit not all the way back overseas.

An international "post / Zip code" like the telephone prefixes would solve that.

Still there's something seriously wrong with the USPS parcel scanning systems if they get Austria & Australia mixed up.

I work for Aussie Post (IT Major Incident and Problem Manager) and the parcel sortation systems are gigantic (http://www.heraldsun.com.au/leader/news/a-behindthescenes-look-at-australia-posts-expanded-parcel-centre-in-sunshine-west/news-story/5a8528cce991470762068eb56aedd077) and run very advanced SCADA control systems. Our 2 biggest sortation systems can happily process 25,000 parcels per hour if we have enough staff and parcels to feed them. The four scanners are 6 axis "tunnel scanners" and the whole system is very cool to watch in action. They are worth at least 9 figures each and they are just the two big ones in Melbourne & Sydney.

So yeah I'd be shocked if USPS isn't using something similar but on an even larger scale.

Garage sale to the rescue.  A nice spool of 22ga hookup wire (red/black/white), for FIFTY CENTS

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=332526;image)
I need a metric reference for the size of the spool.

MFHS&F - I like that!   :-DD  Right up there with SWMBO (She Who Must Be Obeyed, though I figure most here already know that one).

I currently have neither an MFHS&F nor a SWMBO.  This is a mixed blessing, in that it permits me to poke about on evilBay without hindrance or restraint.  This unchecked ability (along with my highly advanced, perhaps likely terminal case of TEA) has resulted in my putting in offers on a little Data Precision 245, and another somewhat less little HP 3450B.

Both were accepted.  Within like 20 minutes of making them.    :o

I'll put it through its paces when it arrives, first thing, as you say, is to terminate or ground couple the inputs and check. That plus enabling the 200MHz bandwidth limit.

Not sure it's got peak detect, it has "glitch trigger" modes for capturing infrequent short glitches or pulses.

My truck might need a chiropractor. I should be right, I'll have some proper lifting gears.

I think it would weigh about 5 tones. Sources vary widely from 3.5 to 7 tones. I'll probably make a trip to the local weighbridge on the way home to know exactly how much.

Bought it for $500 but the final cost will probably be double by the time I get it home.

One Plus 5. My Sony Xperia is becoming very slow and sluggish, despite being just half year old. The Android 7 upgrade totally ruined it, and there's no way back. After using 4 Xperia phones in a row, each with their big issues, I guess I will never buy another Xperia.

You should get one of those: https://en.m.wikipedia.org/wiki/Nokia_3310#/media/File%3ANokia_3310_grey_all_sides.jpg
I use to have one. Not often it would get sluggish or crash.

I personally gave up on finding good phone/computer/tv... by the time you walk out of the store, the hardware is superseded and the software updates eat up 80% of the device's capacity. And then, within months (2 years of you are lucky) the software isn't supported by anyone anymore.  |O

To be honest I don't need 1GHz either, but then I also don't have all that much need for serial decode and  what need I do have is probably adequately met by a cheap USB logic analyser and a copy of sigrok.

I thought the price very reasonable actually - it was half what the vendor originally wanted and 25-40% of what similar 'scopes fetch on eBay. I just have to hope my hunch about the trace noise is correct.

I wanted 4 channels as frequently two is limiting and I wanted 200MHz - see the thread in Repair about the PM3394 digitiser board where I needed to chase a 10-20ns logic pulse - that's going to be very difficult to see on a 100Mhz scope. I considered new 'scopes but 4 channels at 200MHz is well out of the bargain basement and prices are heading into mid 4 figure sums eg £2252 inc VAT for a Rigol DS4024E which I cannot justify for hobby work so less than a quarter of that for the LeCroy seems pretty fair.

Traces look normal enough. The inputs are wide open, so they might quiet down with something connected.
The LCD appears uneven and darker at the top. This is common for these scopes and their DDA and SDA variants. The culprit is a little reflector foil installed behind the backlight CFL tube. With age, it curls and partially obstructs the tube. The bottom of the screen is less affected because of increased light diffusion further from the tube. Refer to this video (https://www.youtube.com/watch?v=8GDGXgQOh5M) for a fix of a similar model. I have yet to do this to my WavePro 960, whose display is much worse off than yours.

I think I looked at that Wavepro 950 a couple of times as well but IIRC the price was slightly high for my taste and I'm not sure whether it has enough processing power to do the math functions at reasonable speeds.

It was definitely a bit steep when first listed - even with the current dire state of the pound it would have been over 1100€ in the Netherlands, the auction didn't go that high fortunately :)

It's hard to know what stuff like this is worth - it doesn't look as though the 950 comes up all that much on ebay but for comparison there are a couple listed with BiN prices ranging from $1400 to $4500.

I think the top end of that is fantasy but a pair of DDA-260's (which are based on the 960) sold for $2200 each. They are a better 'scope as, apart from a 2GHz front end, they have the full 64M of acquisition memory so taking that into account $1400 for a 950 is not completely unreasonable.

This one could have been a bargain for someone though: http://www.ebay.com/itm/LeCroy-WavePro-950-Oscilloscope-4-Ch-1-GHz-with-manuals-needs-repair-/272668492826 (http://www.ebay.com/itm/LeCroy-WavePro-950-Oscilloscope-4-Ch-1-GHz-with-manuals-needs-repair-/272668492826).

The main reason I can think for channel 1 and 4 not working is that the 'scope has been set in 2 channel 8Gs/s mode  :-+

Quote
and I'm not sure whether it has enough processing power to do the math functions at reasonable speeds.
It seems common of the 'scopes of this era and, perhaps more so, of the 1990's that things were pushed a bit on processor power front. I suppose the argument is that it is better to have a slow FFT (or whatever) than no FFT.

So you think, young Grasshopper! :-DD  I had one for quite awhile.  Quite the pain in the keester.  Sucked poorly at removing solder, but did a real good job of burning me a few times.  Used it until I could afford better.  SWMBO asked, a couple of years ago, what I wanted for Christmas.  Santa brought me a ZD-985 desoldering pump.  Lots of funny looks from her, but, in my defense, she did ask.  When I threw mine in the trash, I cut the cord off of it so no one would try to use it.

Well, the beast arrived this morning so I've just had a 1st look.

My initial thought was "wow that's big". My second though was "No, it's ******* enormous". On paper it's only a bit larger than the 9354 but in real life it seems to dwarf it. The fans are a bit loud as well - my 9354 is whisper quiet in comparison but I did change the fan on that. I believe that there are louder 'scopes but this does make its presence felt in no uncertain terms.

However I'm not at all sure changing the fans on the 950 would be a good idea - LeCroy ADC's are notoriously good at frying themselves without adequate airflow and this beast looks like it needs good airflow

Traces look normal enough. The inputs are wide open, so they might quiet down with something connected.
They are pretty noisy to be honest - the flat top of a square wave is a thick band about 0.2 divisions high at something like 1ms/div.

Grounding the input does not change things. Turning on the bandwidth limiter tames it especially the 20MHz limit (a bit unworkable for day to day use) but does not remove it completely, choosing a faster timebase makes it less noticeable. Both of these observations suggest that it is high frequency noise in the ADC input.

Using some averaging in the maths package removes it completely.

Is it too noisy, or unusually noisy?

Taking the latter point first - no, I don't think so. At least there are any number of photos of these 'scopes on the 'net (or the DDA260 variant) which show similar trace thickness. To be honest it is probably only slightly worse than the 9354, but it is visually much more prominent and I wonder whether this is in part due to the display technology and the slightly higher resolution of the 9354 display - 810 x 696pixels compared with 640x480.

Is it too noisy? Umm, yes it might be. Some things will help such as the BW limit and making sure it stays in 4Gs/s mode rather than switching automatically to 16Gs/s mode with only one channel (that makes it noisier) and I need to give the manual a thorough read (think I'll re-watch Dave's video on the subject as well) but I do find myself wondering whether I can actually live wit this as a day-to-day 'scope.

The LCD appears uneven and darker at the top. This is common for these scopes and their DDA and SDA variants. The culprit is a little reflector foil installed behind the backlight CFL tube. With age, it curls and partially obstructs the tube. The bottom of the screen is less affected because of increased light diffusion further from the tube.
It's not bad - maybe a little dimming in the top left corner but not enough to make me want to take it apart.

That video you linked was a bit frustrating because he did not show the appearance of the display before he took it out of the 'scope.

New displays still seem to be available around the $100 +/- $25 mark.

Photos in due course if I have time.

So you think, young Grasshopper! :-DD  I had one for quite awhile.  Quite the pain in the keester.  Sucked poorly at removing solder, but did a real good job of burning me a few times.  Used it until I could afford better.  SWMBO asked, a couple of years ago, what I wanted for Christmas.  Santa brought me a ZD-985 desoldering pump.  Lots of funny looks from her, but, in my defense, she did ask.  When I threw mine in the trash, I cut the cord off of it so no one would try to use it.

+1 for something like the ZD-985 I have the "duratool" equivalent and it is a lifesaver for getting stuff off a board.

Yeah, as I said above I needed to watch some of Dave's videos again - I knew he had covered this but could not quite put my finger on the details. In fact having watched about half of EEVblog #601 I realised I hadn't taken account of the much longer trace memory in this 'scope than my 9354.

Bingo - the acquisition was set to 100k points - a quick play with the 'scope confirms that bringing it down to something more reasonable reduces much of the noise, as expected.

At similar settings the trace noise is not that different from the MDO3104 in Dave's video.

It underlines the fact that you are going to do better on ebay if you understand what you are selling :)

My thoughts also, I'd have thought .9 mm is quite thick even for 1 mm through hole (i normally use .56 mm). That said, I could see it being useful for soldering physical mounting holes for connectors.

The size is slightly large, but I'd be OK with it. I'm more concerned about the wetting of solder joints. I wouldn't want to have to use lots of additional flux to get a good bond.

It solders just fine, this is good old 60/40 lead solder  :)
Its a bit smokey for my liking (thats the flux), lucky hay fever is supressing my sense of smell.
I scored a soldering fan earlier, for when I need it.

I do mostly through hole stuff at home so the .9mm is ok.

I will be on the look out for some more finer solder.

Im a cheap skate so I always love a bargin  ;)

I'm the same way, especially with cars. Unfortunately, my wife is the exact opposite with cars. Soon as a car needs any repairs over $500, she starts thinking we need a new one. And it's not just with her car, but my daily driver as well. Then we always hash out the same old argument about ongoing repair costs for an older car vs going back to having a car payment. I can't stand having a car payment. I'll take an old jalopy that I'm constantly having to fix over having a car payment any day.

Ask her ( if you dare) if you should trade her in for a new model as soon as any bill for anything she wants comes to over $500. No need to buy a new car while the old one still does the job, and does so for less per month than payments for a new car, which in any case is not an asset but a liability, and which is best bought as a year or three old one ( with service history) at a good discount.

I tottaly agree with you.

We should care a car as much as it can do the job it was intended to. I had a car in my family for 20 years. When the car reach its 15 years my fathers bought a new one and gave the old one to me. I only got a new one (a few weeks ago) when the repairs costs allways over 150€ (a new exaust pipe, a new clutch, a new MAF sensor, a new EGR valve, etc etc etc) and a couple of days in the repair shop. I have no conditions to be half a week without a car, so I really needed another one.

Unfortunatly I'm not like this with tools and gadgets. When it starts to fail I buy a new one and then fix the old :-/O  ;D

I made the last payment on my truck in 2008. They had been about $275 a month. Since then, repairs and maintenance have totaled almost $1700, or about $16 per month. Of course, I don't drive much so that helps, but any vehicle that's paid off is far cheaper to own than a new one. You would have to be needing a serious major repair every year (motor, trans, etc.) before a new vehicle makes sense.

This is what I try to explain to my wife, but even though she has a business logistics degree and is no slouch at math, she's not swayed by the "do the math" argument. Instead, she insists that once a car starts needing "major" repairs (which as I said in her mind is anything over $500 or so), it's all downhill from there and the car just becomes a money pit. She's always afraid that we're going to throw $500 or $1000 at it, then next month something else is going to break, etc, and that therefore you shouldn't throw any money at it whatsoever. Of course, this all excludes regular maintenance things like brake repairs. If we have to spend $800 to fix the brakes because the calipers are shot, she doesn't think anything of it, but if the fuel pump goes bad after 140k miles, she thinks it's an indication that the whole car is shot. I tell her parts are parts, and none of them last forever, and what's the difference between a brake caliper and a fuel pump in that regard? Neither of those things needing to be replaced means that the whole car is shot. But it's all lost on her. I really think it just comes down to fear of the unknown for her. The difference between brake calipers and a fuel pump, in her mind, is that she has a basic understanding of how brakes work, and what a bad brake caliper does or doesn't imply about the health of the rest of the car. But a fuel pump is a mystery to her. In her mind, the fuel pump is an "engine" part (even though on most cars these days it's located in the fuel tank), and if an "engine" part is going bad, what else is going on with the engine that just hasn't hit us yet? Oh, crap, dump it!

The problem is that sometimes you need a crystal ball to know what to do.

I drive an '06 Celica - it had an "expensive patch" in 2015 having blown a hole in the power steering fluid cooler, the clutch finally gave out and needed replacing and the following service saw new disks and pads all round as well as new rubber on all four corners. I think it cost me £2k that year.

But it's settled down and hasn't needed anything major since then so, while I would love an new motor I can't really justify the expense and am happy to keep the Toyota running. It helps that they are generally recognised as a reliable marque.

The "family" car, however, was an '05 Saab. As this was from an era when Saab built to a specification not a price (and went bankrupt as a consequence) you would think it ought to be OK. Unfortunately it had started to become unreliable, breaking the main drive belt more than once and I suspect our mechanic had not quite got to the bottom of why. As the belt drives the power steering pump failure left my wife without power steering rather suddenly and she does not have the physical strength to handle the car without - so it all got a bit frightening.

Just before Xmas 2015 it blew the turbo. I got that fixed as we were due to travel in it and I did not want to be forced to buy a new motor in a hurry but decided that enough was enough. Just before we picked up the replacement and on the day I was going to list the Saab on ebay it threw its belt again as well as half the sump contents onto the road.

That car felt like it was going to be a) a serious money pit and b) unreliable which is a bigger problem when you need to use it every day.

Had I had a working crystal ball I might well have sold it after the first broken drive belt.

Yes, I know, had I held faith etc etc. I'm not buying it :)

Just to be clear, this is not at all the point I was making, nor one I ever would make. My wife's default position about a car that's starting to need repairs is to immediately assume it's a money pit. But that doesn't mean my default position is to assume it's all fine and dandy, or have "faith" in it just needing this one part and then everything will be perfect.

Rather, I think your examples clearly demonstrate that neither thing can be logically concluded early on when the car is just starting to need repairs. But if it's just the one thing, for now, and the car has otherwise been reliable, even a few $500 repairs need not be cause for alarm. Instead, you just keep an eye on it, and watch out for red flags. In the case of your Saab, the repeated belt failures were a huge red flag (barring you or your mechanic being able to identify a root cause such as a bad pulley or some such thing).

Bottom line, there's a risk associated with either course of action. If you rush to the conclusion that the car is junk and immediately sell it, the risk is that you're potentially giving up a perfectly good car that just needs a few repairs. On the other hand, if you assume the car is good (like homeowners who insist their dump of a house has "good bones") and keep throwing money at it for expensive repairs, and it might actually end up being a money pit. The only sensible thing to do is keep your wits about you and take it one repair at a time. Reason it out, weigh the evidence, do the math, consider the best and worst case scenarios and try to arrive at an educated guess as to where your car falls in between those lines. And then the next time something breaks, do it all over again.

In my most recent case, I had a Ford Explorer with about 140k miles on it that had been amazingly reliable. I never had to do anything to it other than the regular service intervals, and the occasional expensive brake job. The engine was remarkably strong given how many miles it had on it, and how hard I drove it. Then the fuel pump went out and started intermittently leaving me stranded. I did some basic electrical troubleshooting to rule out things like a short or open wire, or a bad ground point, and everything pointed back to the fuel pump itself. It would have cost me around $400 to do the job myself, or $800 to have the mechanic fix it. I have all the tools necessary to do the job, the only thing that I was a little wary about was dealing with proper and safe removal of the fuel tank. But I always err on the side of being overly cautious, and I was confident I could get it off safely. By my wife wasn't having it. To her, as I said, a bad fuel pump meant the engine was going bad, and she was convinced that this was just the beginning of a cascade of failures. To me, it was a fuel pump with 140k miles on it that was probably only engineered to last 100k miles, and in fact I had found numerous threads on various forums about Ford Explorer fuel pumps going out, with nearly identical symptoms. There were even step by step repair guides, videos on YouTube, etc specifically dealing with replacing the fuel pump on Ford Explorers.

As an aside, evidently a lot of people just cut a hole from inside the passenger compartment in order to get access to the fuel pump without having to drop the tank. Way too scary for me to attempt. I'm sure I'd be that one guy who blew himself up by accidentally cutting into the fuel tank with an angle grinder.

But hey, let's get this thread back on topic. Today I received the much talked about UNI-T 210E in the mail.

In fairness, I've had my eye on this for quite a while now, long before I discovered EEVBLOG. Oddly enough, this actually dovetails with the car repair tangent, since I was first drawn to the 210E back when I was troubleshooting a battery drain on the previously mentioned Ford Explorer. I was looking for an affordable DC current clamp so I could monitor current draw with the car off, but without having to put my poor ol' Radio Shack DMM in series in order to measure it.

Hopefully, I won't need it to diagnose any car electric woes any time soon, but I'd love to be able to take quick current measurements on the bench just as a sanity check, without the hassle of putting a meter in series.

;) saw almost exactly that side profile today, on a nice 1980's vintage Toyota hatchback, which, despite living in the corrosion capital of the planet, still was in reasonable condition body wise. I guess Subie and Toyota both shopped for the plastic parts and body panel dies for those models at Toyoda to make the models for various markets. Here the locally made models all had panels pressed at Rowen ( later Metal Pressings Inc now just Toyota Press plant) using local steel and mostly imported dies.

Yes, I was trying (badly I suspect) to make the same point. You can't tell (and I agree one repair does not automatically mean a money pit will open up) but you make a judgement - in the case of the Saab it was after the turbo blew and that decision seems to have been justified when it suffered another potentially expensive failure only 5 months later.

The "held the faith" comment was not really directed at your earlier post - it was just in case someone tried to suggest "one more fix and it would have been OK"

Cars generally are money pits though. However I can't say I'm in favour of the current fad for avoiding maintenance costs by continually leasing vehicles. Yes you get a new toy every three years but they keep bleeding you dry for it.

Debt makes the money that makes the world go round after all.

Yes, I know, had I held faith etc etc.

Just to be clear, this is not at all the point I was making, nor one I ever would make. My wife's default position about a car that's starting to need repairs is to immediately assume it's a money pit. But that doesn't mean my default position is to assume it's all fine and dandy, or have "faith" in it just needing this one part and then everything will be perfect.

I have a '98 ford explorer, still on blocks, the transmission or something went out. I was stubborn and wanted to fix it, long story short a few grand in i had a new transmission and it did the same. I kept working until one day a block i had a bottle jack on broke and sent 500 pounds of metal screaming for my head, it stopped so close to my face that you couldn't have fit a piece of paper between me and it. I stopped working on it that day because it was made very clear to me it was either the truck or my life (metaphorically speaking), though kept it on blocks because i am stubborn. 

My point, if you can say this ramble has one, is that some vehicles are just going to drag you down with them.

Bought a cheap synthesizer module rack (Doepfer A-100 LC1 (https://www.thomann.de/gb/doepfer_a_100_lc1_low_cost_case.htm)). Painted it with acrylic blue, now it looks professional  :)

(http://i.imgur.com/cQjrNcc.jpg)

Using it in combination with breadboards works surprisingly good:

They can't do this just for the color, I would need to build a scope with it, and which looks the same :P

But now that I think about it, wouldn't it be nice to build your own rack of lab instruments, or is this already done? So far I've seen only synthesizer modules for this Eurorack (https://en.wikipedia.org/wiki/Doepfer_A-100) type system. And in the audio world this format is often used, so you can add and mix modules from different vendors without problems. All share the same power supply on the back (+/-12V and 5V) and are available in standardized widths, with 1 HP the width granularity (5.08 mm = 1/5") and 128.5 mm height (5"). I bought a few blank front plates as well for DIY modules, they cost only a few Euros, depending on the width (you can see a few mounted, in the video).

I know there is the 19" rack format for professional lab gear, but this needs really a lot of space for some small hobby lab. And a 19" case is more expensive than just a small front plate with a PCB mounted on the back and a common power supply for all modules.

Sounds like you are describing the Tektronix TM500/TM5000 line, introduced in the early seventies. Hameg had (has?) the less ambitious HM8000 line. They had edge connectors that carried AC and DC power rails and some optional unused pins for interconnections between modules. They had power supplies, pulse/sine/function generators, DMMs, frequency counters, even oscilloscopes and some specialized gear like differential and current probe amplifiers. The motivation behind that was that transformers were expensive, and so were displays.

This way you could have say a function generator without a display, and if the user needed an accurate frequency read-out, they would add a frequency counter plug-in that would be internally connected to the function generator. If you wanted an accurate level read-out, you could add a DMM plugin to do the same. Ultimately these instruments required much more R&D than stand-alone because the power, EMC, thermal and size constraints they had to work against. Especially when cheap LCDs removed the cost advantage of sharing displays. Usability was also compromised due to the much more limited front panel real-estate.

Another application was building custom systems. You could use a function generator to drive the VCO input on another generator to sweep. This way you could generate complicated signals. These days, you just add another sweep generator inside the function generator, or use an arbitrary waveform generator. If you want a power supply that can output arbitrary waveforms, you just add an arbitrary waveform generator inside the power supply. Tektronix sold the TM5000 lines to Tegam in the late eighties, who put it on life support for a number of years before killing it.

These days, when you can find cheap AC-DC and DC-DC power supplies, and LCDs can be bought for a few $, I do not see the advantage. If you want something that looks nice together, build instruments in matching cases that stack well together, like you see on many half-rack Agilent/Keysight and Keithley instruments.

Post by: FrankBuss on July 24, 2017, 04:55:12 pm
Right, probably it doesn't make sense these days anymore, and half-rack size looks good. I wonder how long these audio modules are available anymore, until everyone uses a PC for it.

No, there's a Sims Metal recycling depot nearby. I could take the bits myself (once my car is registered again), but it's simpler to ask a guy who lives round the corner and does scrap metal collection as a kind of retirement hobby, to come take it away. I have about a trailer load of scrap steel for him to take. He's coming Wed morning. The yard will look a lot better after that. The other half of that old car is cut into easily liftable sections.

The wheely bin mostly gets used for all the plastic panels scrap, from disassembling photocopiers, TVs and the like.

A bit of excitement today, bought this

(https://image.ibb.co/mQOUkQ/20.jpg)

It'll be a couple of weeks before I can pick it up but I'm looking forward to it.

I am EXTREMELY envious. Currently I need to machine an aluminum disk 306mm dia and 45 mm thick, 200mm dia hole in the middle, and some large radial holes through it. My lathe has only about 115mm (4.5") radius throw, so cannot do this piece. Still looking for a solution (other than paying a local fabrication shop to do it.)

I also envy that you have the spare space to set that monster up. Even if I found a big lathe for free, housing it would be near impossible.  Hmm... I suppose another sheet metal 'garden shed' would be required.

How did your move go? (Oh wait, two weeks, not yet huh?)

I think you're on the oz east coast (?). Join up and poke around the CNC and other metalworking forums on that site.
I've seen a few guys there trading jobs / skills and even just doing jobs just for the love of it.

$500 - yes, I read that. I meant if _I_ found one for free. Which is the kind of thing that does happen.
Can't wait to see your lathe-mobile. You mean _into_ the truck? Pretty solid ramps required. And a winch.

And from there found: https://www.machines4u.com.au/search/Lathe/?page=2 (https://www.machines4u.com.au/search/Lathe/?page=2)
Have a look through. There are multiple instances of relatively modern, large CNC lathes listed for $1.
Too bad all the ones I've found so far are way too big and heavy for me. I suppose that's why the token price, among other things.

Yeah, they do. The course fees went stupidly high as of last year (my daughter encountered that.) Would now probably be cheaper to buy one's own good lathe. Plus at my age, don't have the time to spare.

Sorry, my misunderstanding.

I actually meant on, not in, the truck. Ramps won't be a problem, I have a pair of tractor ramps able to handle 6 tonnes.
Of course, winch for backup and safety but I'm expecting the electric drivetrain to be sufficient.

Cheap, accessible and decent condition don't often come together for used lathes unfortunately.

I got tired of my cheap digital calipers, so I went to the shop and emptied my wallet. Mitutoyo digital calipers. I hope this thing doesn't consume batteries like no tomorrow and doesn't constantly lose it's reference point. To be fair, for a $15 Shenzhen Special it worked quite well for several years.

One weird thing, this Mitutoyo can't measure in freedom units :o What the hell Mitutoyo. For this money you really couldn't put a button on there?

on a known test block, i would regularly get a more accurate reading using manual verniers over other apprentices using digital ones.
admittedly, that was apprentices.

When i have had to use them, the  Mitutoyo ones were generally the best. battery wise, i think we got a good couple years out of them used once a week or so

Those manual (without clock) ones are difficult for me to use, my eyes don't cooperate. I basically see those small lines double unless I look at them at a funny angle (astigmatism, but not really enough to make proper glasses).

Many people make the false assumption that a digital readout is dead exact. It's just wrong. I've seen several digital calipers with 0.001mm resolution displays... Just nonsense. I highly doubt the measurement system does better than 0.01mm. At this point you really need a micrometer if you want a digital readout.

As with any measuring equipment, resolution is not the same as accuracy, and extra resolution without extra accuracy can be useful in some situations.

For me the only advantage of digital readout is easier relative measurements without mental arithmetic (bonus points if you use fractional inches). So I am quite happy with the traditional vernier calipers.

Another thing to be careful of with those cheap digital calipers: Some of them don't turn off completely. Turning them off is only turning off the display, so the batteries die pretty quickly whether you are using it or not. To test this, turn off the calipers and then press the "change units" button. Then turn it back on. If the units have changed, the calipers is only switching off the display. I have two cheap digital calipers with different brand names that do this. A real pain, because you have to remove the batteries when it's not in use.

€130.

If you really want to go crazy, they also sell an IP67 rated model for almost €400.

When buying tools I usually get a cheap one first, just to see how often I use it. When I use it often enough and it breaks I'll get the better ones.

My cheapie does the same. I pulled the battery out every time, but it wears the battery contacts out. Had to clean and bend them several times, that just gets old after a while. I've seen someone who modded a tiny slide switch in the case, that might be worth a try.

You got the Mitutoyo 500-181-30 which is a fixed metric digital caliper. If you want a similar model that can switch between millimeters and inches you'd need the 500-196-30 which also features a handy thumb roller.

Battery life of these Mitutoyo calipers is great. Expect several years.

I just picked up one of these the other day. It's no Mitutoyo, but it's good enough for the women I go out with. I don't need to measure anything down to the thousandths, so this is fine for my needs. I just got tired of reading my old analog calipers. I especially hated having to use a calculator to convert back to the nearest 1/32" or 1/64". This one has a fraction mode, which is really nice. But yeah, if I ever find myself needing better precision, I'll get a Mitutoyo.

just got in this.  non-fixed stereo USB webcam

for a 3D Split Screen PC type video microscope project.  :-\
it turns out that this stereo stereoscopy headed webcam is just two USB webcams with a common USB port.
to mix two webcam images I will need software. that is not provided.  :(  but it is 1280 x 960 High definition x 2 .  :-+

non-fixed must be the video synchronization . not the image senior pcb heads  :palm:
USB webcam is by www.keyetoncctv.com (http://www.keyetoncctv.com)  this link maybe buggy  behind the red curtain

Said to have released the magic smoke. We'll see, going to pick it up in the afternoon.

Nice score and not to expensive.  :o (assuming its a easy fix...)

Well, it indeed smelled like a campfire when I picked it up. After spending an hour with screwdrivers, eyes and nose I found the culprit hiding behind some screening: the only freaking tantalum in the whole instrument!  :palm:

One weird thing, this Mitutoyo can't measure in freedom units :o What the hell Mitutoyo. For this money you really couldn't put a button on there?
This is the case with the European Version of the Mitutoyo calipers. If you want the switchable Mitutoyo, you need to buy the USA version.

My absolute favorite caliper is made by MAHR in Germany
This is the model 16 EWRi
It connects via wireless USB adapter to the PC and adds the measurements nicely to Excel.
The numbers are huge and is very well built.
It is a pleasure to work with this caliper.
And of course, it is switchable in the units.

(https://www.eevblog.com/forum/chat/show-your-favorite-and-mostly-used-benchtop-psu/?action=dlattach;attach=335852)
Actually arrived Wednesday, I haven't yet had a chance to open it up, but the controls seem smooth and the cosmetic condition is excellent. I'm planning on re-capping it before applying power to it. This should become my main supply for any dual rail circuits.

That one's a beauty, ManuelMcLure. Some of us on the forum have ended up with a varied collection of Power Designs supplies. Don't be surprised if some more find their way onto your bench. They seem to like company. ;D

Also, since they're linear supplies, you may find that the caps are in better condition than you'd think for their age. You may want to test them before replacing if you like the look of the vintage cans (or restuff).

Yeah, I must say that the aesthetics of the front panel were a big part of my decision to buy that supply. I mean, how could I say no to those puppy-dog meters?

Thanks for the tip. Being a beginner, I don't have a capacitor leakage tester, but I can at least make sure they aren't physically leaking. Hopefully they're good, because I can imagine replacement caps are not going to be cheap.

Gambled $20 for something I don't even need ....  :palm: , an used TDK-Lambda HWS1500-36 1500 Watt rated PSU. It has a dent on top of the case, tested on site, powered on, output voltage measured with DMM is on spot, but no load testing. Hope I win this gamble, wish me luck.

It has two beefy connectors (comparison with TO-220 body), the biggest connectors I had ever own.  :o

But now that I think about it, wouldn't it be nice to build your own rack of lab instruments, or is this already done? So far I've seen only synthesizer modules for this Eurorack (https://en.wikipedia.org/wiki/Doepfer_A-100) type system. And in the audio world this format is often used, so you can add and mix modules from different vendors without problems. All share the same power supply on the back (+/-12V and 5V) and are available in standardized widths, with 1 HP the width granularity (5.08 mm = 1/5") and 128.5 mm height (5"). I bought a few blank front plates as well for DIY modules, they cost only a few Euros, depending on the width (you can see a few mounted, in the video).

Even if it doesn't make sense commercially, I just started with it. Now I have already another +12/-12/+5V fixed voltage power supply  :)

In its natural habitat:

Don't know where I bought the banana jacks, was in my parts bin, but the blank panel was this (https://www.schneidersladen.de/en/doepfer-blindplatte-4te-20mm.html). So you can basically build a half decent looking DIY Eurorack module for EUR 3, if you have all the other parts for it. I've seen even panels made with PCB boards, which is a nice idea, because they are so cheap these days, you can add some nice looking silkscreen, and you don't have to do the drills yourself.

Just a remark to the "Wow, not bad, only 4.8 mV off".
Thats 4.8 mV off to the volatge shown on the PSU meter, but does not tell anything regarding the real accuracy in my opinion.

Another thing to be careful of with those cheap digital calipers: Some of them don't turn off completely. Turning them off is only turning off the display, so the batteries die pretty quickly whether you are using it or not. To test this, turn off the calipers and then press the "change units" button. Then turn it back on. If the units have changed, the calipers is only switching off the display. I have two cheap digital calipers with different brand names that do this. A real pain, because you have to remove the batteries when it's not in use.

McBryce.

My cheapo digital calipers passed this test, but I noticed that it will turn on when I move the slider.  Looks like the battery is staying out when not in use!

I wonder if in another ten or fifteen years there will be people searching for equipment with 7 segment LED displays with the same zeal that more than a few of us here have for nixies...  LOL  - now might be the time to start buying examples of it in order to beat the rush!

I found this dusty beast last year at Apex, and of course being old and unusual it followed me home.  The digits are over an inch tall, and the electronics are all discrete parts- nary an IC in sight.

That is a nice multimeter, though with your comment about 7 segment displays being as hot as nixies in a decade; does that mean we should just starting buying up nearly everything? Great excuse to give in to TEA or GAS.

Finally broke down and ordered one of these Smart Tweezers with Bluetooth. Hoping it will be handy to verify parts during prototyping and pick-and-place setup.

Seems to be much more convenient than an LCR with leads and (theoretically) can go down to <1pf capacitance.

The C readout is good for even sub-pF, but the L readout can't go reliably down to even 100nH.
Also, prepare for the buggy firmware. UI can get stuck when being charged, settings can get lost, and buttons don't always respond.
And what did the manufacturer say about these issues when you contacted them......you did didn't you ?

I was a bit concerned that I might wind up bidding against someone here, but as I'd seen no mention of it on the forum decided to take a crack at it and sniped with a relatively low bid.  I was hoping that because the guy is a noob (feedback in the teens IIRC) that some might be dissuaded from bidding, reducing the potential (fa-dum-bum - it's a voltmeter, get it?  ;) ) competition. 
(Yeah, I know, that was horrible.   :palm: )

Finally broke down and ordered one of these Smart Tweezers with Bluetooth. Hoping it will be handy to verify parts during prototyping and pick-and-place setup.

Seems to be much more convenient than an LCR with leads and (theoretically) can go down to <1pf capacitance.
Hi
What does the Bluetooth connection give you and where ar these from?
Thanks
Neil

The BT connection allows a PC or phone to display and record the measurements. They also provide a LabView driver.

I suspect that having the info on a large PC screen will make it easier. I got is from one of the eBay sellers (hoping I don't get ripped off). Fingers crossed.

That's your German law, that is why your speedcameras take pictures from the front of the car.
Almost all other countries incl. other european countries take the pictures from the back and use the license plate to id the carowner not the driver, and you as carowner get the ticket.
BTW If you get caught red handed here in the Netherlands as foreigner you have to pay the policeman cash at the stoplocation or your car gets impounded.

I finally went to pick up that lot I got on eBay:

http://www.ebay.com.au/itm/263014645608 (http://www.ebay.com.au/itm/263014645608)

Well worth the money. I'll put up a photo gallery soon enough. The highlights are probably the Keithley bench DMM, two preset counters (nixie tube display), two programmable oscillators, an LCR bridge, and the 16 channel HP logic analyzer.

Cannot live ..... without ...... TV

I know the feeling. One morning a couple of years ago I was playing a game and the TV started making buzzing noises, then there was a loud pop and everything went dead except the power LED. It was almost certainly a bad cap in the power supply, but the TV was 7 years old and only 37" at 1360x768, so I took a shower, got in the truck and headed to Walmart. Less than 2 hours later I was back to playing my game on a new 42" 1080p LED Sanyo TV. Funny thing is, to this day it has never been used to watch "TV".

I just ordered a really cheap X-Y table, which appears to be a (Shenzhen) LiYang 6300. (their cheapest)

http://www.usbearth.cn/product/60645441688-219344457/Miniature_precision_LY6300_multifunction_Milling_Machine_Bench_drill_Vise_Fixture_worktable_X_Y_axis_adjustment_Coordinate_table.html (http://www.usbearth.cn/product/60645441688-219344457/Miniature_precision_LY6300_multifunction_Milling_Machine_Bench_drill_Vise_Fixture_worktable_X_Y_axis_adjustment_Coordinate_table.html)

I'm likely going to need to get some new clamps for it, the "clamps" it comes with look really low quality (but a relatively cheap upgrade) 

Some images below. Its aluminum, not steel.

It looks a lot like the Proxxon.

Since they look so similar, I wouldnt be surprised if LiYang was the OEM for Proxonn's x-y table, if so the exact match to the proxxon (have no idea if thats the case)  would likely be one of the nicer 63xx models)

This is their ultra cheapie so likely its not built to the same degree of care.

There are a lot of US vendors for this product (under a lot of different names) and the reviews seem mixed, but generally positive.

I'm on a really tight budget right now and just can't afford to spend more.

This will help me do the #1 thing I want to do- make it easier to drill via holes in straight lines at not too imprecise intervals in PCBs and drill holes in cases for my misc. devices in the right spots.

Any ability to "drill sideways" will be gravy.

I'm not really expecting to be able to do that with such an inexpensive device.

---

So this arrived and it has a few issues.. the handles for this model are solid aluminum and dont swivel, which makes it harder to crank. And the back cover over the gears is a pronlem, its binding..


Little mill has potential, though.

But this one is going back..not as pictured.  I may buy the upgrade model, if its built stronger.  It fits my drill perfectly.

And a rare sighting of a glass CRT TV still in use. Yay CRTs! I like them too. The last of the actually maintainable video displays

 :(
Sadly that CRT TV died today  :--

Looks like the vertical scan is not working, just get a bright horizontal line across the screen.

Looking at getting new LCD flatscreen. If anybody in uk want the old tv, let me know

Too bad, you aren't local to me, I would give you a perfectly good working RCA 27" CRT TV.  :-+ 
Another note, I didn't buy it but my son gave me a cheap Dynex 32" LCD TV.  He was going to put it out because the sound stopped working and just replaced it.  I was going to crack it open but I decided to use it as a monitor on my workbench.  The space I lose is worth it for my tired old eyes, I had a 22" monitor.  No need to worry about lack of sound.

No, it  is not but still a nice piece a gear. I'll see if it still works when I get back home.

Another nice piece of history is the Tektronix 175 current adapter for the 575 curve tracer. Unfortunately, the curve tracer wasn't there. I hope to find one I can afford one day.

Yep, I was thinking the same things. The reason we didn't collide was that it was being shipped via USPS, which would have cost about double the price of the meter (it's not even leaving the country! :palm:). USPS is usually not the way to go for anything bigger than will fit in a flat-rate box.

I have no idea why I bid on this. No one else did, so now it's mine. According to the paperwork that was included, it left the factory in 1980 and it's rather crusty but does work. The battery pack was starting to corrode, but nothing else was damaged, so I just removed it. It has a really nice manual with full schematics, block diagrams, timing logic flow charts, etc.

May be you can show us the inside.

It reminds me of a small counter from Philips but that one needed mains power.

I must be closer to him, then, as the shipping for me was a bit less than $14.  That is definitely something I consider, though, and on something like this will figure it's worth $XX to me, so my max bid will be $XX-shipping.  IIRC I decided my limit on this one was about $45, so I'm happy with the outcome.  It left Pittsburgh two days ago, and is currently enroute and in limbo as far as USPS tracking is concerned.

The TV was an epic fail.  Neither Hospice thrift or Habitat for Humanity thrift stores wanted it, they only take flat screen TVs :wtf:.  Fine, it's on the curb.  We have scavengers going through the sub division regularly so it will be gone quickly.

Yep.  If only the things we buy could get to us as fast as the resulting credit card bills seem to!  Though at the same time, it's amazing how much our expectations have increased.  I remember ordering things back in the late 70s as a kid - fill out the order form, get a parent to write a check for you, mail it off and wait.  And wait..  And wait...  Typically at least two weeks, as I recall.  Seeing a UPS truck on the road in a residential area was a rarity.  These days, NOT seeing one is almost unheard of.  Along with two flavors of FedEx, too.  And as for two weeks, now it's more like "What do you mean it's going to take FIVE DAYS to get here?!?!??!"    :rant: :rant: :rant: :rant:  "I want it NOW!!!"

Well, it arrived today, and is complete and in decent physical condition, with both feet and the tilting bail.  And, as shown in the listing, it does power up.  Unfortunately, it does NOT display any measurement when volts are fed to its input jacks.  If the input polarity is reversed, the '+' indicator goes out, but the '-' does not light...  Time to dig out the manual and attempt to shoot some trouble...

*: This regulation gives me big trouble even till now. My Alipay account is connected to my mom's card since at the time I first shopped online I was 17, so I have to use my mom's card. Now, since my Taobao account uses my name, and my Alipay account uses my mom's name, I can't pass real name verification, so I can't sell things on Taobao. Taobao doesn't allow Alipay rebinding, so my Taobao account will be stuck at this condition forever. Now, I can start a fresh new account, but then I lose all transaction records (I have a perfect credit and transaction record), and the perks (such as instant refund, higher trust level and other perks) it provides me. What's funny is after moved to US, and my Alipay has been associated with my Wells Fargo card (as well as a Chinese card, both under my name), it still shows my mom's name on account owner section, and I still can't pass real name verification.

daaaaamn.... well, that's one way to stop account farming and reputation transfer!

Probably a good idea for you to start a 2nd account and use it for small things just to build it up, till it's eventually good enough to jump over to.

*: This is not a good thing, IMHO. Nowadays Chinese consumers scam sellers very often. Usually someone will threat to leave a negative feedback in order to get partial or even full refund, or someone will buy silicon lottery kind of things (overclockable CPUs, LCDs, etc.) and bin the best and return the rest, which is unfair to other buyers as well as the seller. Recently there is a trend that people buying high end GPUs in bulk, mining for 7 days, and return them, so they make 7 days worth of free mining income, and then order another batch.

If there's any possible means of running a scam, someone will discover it and try it. If it turns out to be successful, then you'll get a million copycats doing it.  :(

It's a shame to see that kind of "activities" growing.
Portuguese people also like to scam ebay/AliExpress sellers saying that the items never arrived or "finding" some deffects to get the money back an keeping the items (stuff under 50$ isn't worth returning and sellers usually give partial or full refund without asking for the item). And then I see some guys questioning about the limitation that some sellers have when selling stuff to Portugal...
Even Italian guys are refusing to sell stuff to us  |O

I wonder why we cannot use a standard sigrok-compatible logic analyzer for USB? I vaguely remember trying to, a few years ago but I don't remember succeeding.

So it must not have been possible.

For starters, most cheap logic analyzers do not support differential signals, so you would need a transceiver to convert the levels. Secondly, few Logic analyzers would have the sampling rate and depth to sample USB 2.0 high-speed. Even the Intronix Logic Port can only do 500 MS/s, which is too slow for a 480 MHz signal. Does Sigrok support any logic analyzers that go above 1 GS/s? Plus as far as I know Sigrok only has protocol decoders for low level USB protocols at low and full speed.

A Fluke 8842A:

(http://i.imgur.com/7MAyzxL.jpg)

I needed a good 5 digits multimeter for my 0.1% precision sum circuits I'm going to build (and probably sell) for Euroracks, so the last EEVblog video was just in time. No need to spend thousands of euros for a modern instrument, if this has the same or better spec.

Unfortunately, as Dave promised, because of his video, probably it was double the usual price (EUR 275), but it has the optional AC measurement unit, and the GPIB module as well, which will be very useful in combination with the Raspberry Pi Voltnuts platform (https://www.eevblog.com/forum/metrology/raspberry-pi23-logging-platform-for-voltnuts/) later for creating characteristics curves, or automatic calibration with a simple Python script (for a +/-10V bipolar multichannel fast 16 bit ADC/DAC module I plan build). And it was calibrated, so I think the price is fair. Tested with a DMMCheck r3 from voltagestandard.com (http://www.voltagestandard.com). The Fluke is probably more accurate than the voltage tester.

The case looks a bit brownish, but that's ok, same as with my vintage C64 computers. Maybe I'll use some retro-bright for it, too :)

Guy, next time you are going to grip thread in the chuck, grab a trio of thin aluminium strips and make some soft jaws out of them, which grip very well and do not mar the work at all. Sorry, do not have that 40mm vacuum hose, and yes it is bleeding expensive, especially as I had to buy a 30m roll of the 2 sizes I needed, so have been simply replacing the sections as they get dirty instead of cleaning them. If you want to cry order the food safe version of that hose, with the same PVC wall but with stainless steel 308 wire as the reinforcement member. That stuff is expensive, makes Watson Marlow Marprene tubing look cheap by comparison for the same diameter pipe.

I got a "True Position" telecom surplus GPSDO card and (after some initial frustration due to my not realizing how much GPSs have improved in the last ten years, in terms of dealing with non-optimal antenna placements) its working well.

It should provide me with a 10 MHz frequency standard to use in other devices, as well as a high quality 1 pps timing pulse which I can use for a great many timing-related things.

Now I am working on a controller (http://www.packratvhf.com/A%20Packrat%20GPS%20Receiver%20Project.pdf) and also need to figure out a good way to make that time and frequency data available to more than one other device without degrading it.

I look forward to having a second NTP server, for example, that uses it's 1pps, to compare to my other server that uses a tiny GPS as its source of timing data.

I can use a slightly modified video distribution amplifier for the 10 MHz - the 1PPS I have to look into, so I can preserve its fast rise time. Its a good way to learn about an interesting area.

Yeah, I know. But I needed make a bunch of those things, and will be needing to make more later. Plus needed to be able to remove from the chuck and put back, still centered. Fiddling with loose soft-jaws didn't appeal, plus crap repeatability. I like my thread-grabber collet thingy better.

I can live with it. Amusingly it isn't even really 'vacuum hose', just hose that doesn't crush under vacuum. Because it has a smell (PVC smell) which means it outgasses some bunch of complex volatiles. Fortunately where it will be used, this doesn't matter. It's only for the big rapid-roughing pump, and has a bellows valve between the hose and the chamber. That will only open for a few seconds during pump-down, and if I get the timing right the volatiles won't backflow into the chamber.
Bought this because I didn't want to even find out how much 1.5 m of 45mm dia stainless concertina hose would cost. Also it's nice to be able to visually verify the pump oil hasn't sucked back up into the hose due to some goof, like the air inlet valve not opening.

Bet most of the small 4v electrolytics on those boards have either leaked or gone almost open circuit though. Sony could never make those capacitors reliable, and they always are a ticking time bomb on Sony equipment.

Mhm... I bought one 41420 year ago, which has self-test error and large offset on both V and I, but works. And by seeing bunch of other 41420As with listed price, couldn't let it pass.
However now I have more modules than slots available in my 4142B. It will be renamed into "unshippables" once all assembled. Even with aluminum chassis/shields it will weight over 40kg. I don't know how I will move once my rent is out  :-//  :scared:

I know the problem - in the recent months I scored Fluke 5440B (repair in progress, some DIY required), 5200A (seems OK) and Wavetek 4600 (repaired) and combined it is around 65kg. These things are beasts, but it was orders of magnitude cheaper than something like Fluke 5700A. I don't want to buy Fluke 5205A for 1000V AC range, as it is another 55kg, so I'm thinking about using Kepco OPS-2000B, 2000V opamp to do the 10x or 100x gain from 5200A.

For far too long now i have not had a decent high current, current-limiting selectable,  variable voltage 230V/115V source at my workbench in my workshop. I see more and more sad SMPS that the owner is desperate to have working again and you have gotta be so careful as we all know....

So i started my next project with this monster (for me) isolation transformer; Specs: 7.5A @ 230Vac or 15A @ 115V....

Next item will be the variac. I'll probably build the whole thing open frame but covered with a 1/2" thick panel of clear acrylic just in case... and use four 60W 'vintage' E27 clear glass tungsten filament bulbs as the current limiting devices... so the thing looks like something out of 1930s Hollywood mad scientist's set.

I stopped using the built-in TV sound when I started using them as computer monitors instead of TVs.

Older CRT TVs did seem to sound better than newer flat screen types though.

Of course, in older CRT tvs they had quite a bit of room, so they could fit proper speakers. Modern TVs, read as flat screen TVs, are not only much smaller but much flatter so the speakers they fit in there have to be smaller leading to a degradation in sound quality. That degradation in sound quality also has to do somewhat with acoustics of the panel and the general quality of the TVs.
I have taken apart a Samsung flat screen TV for fun and inside were what looked like cheap speakers, looks can be deceiving though when it comes to audio never trust how something looks.

HP 3326 dual oscillator - 13MHz can be either different phase or frequency.

Are you sure it's not a kit? It immediately reminded me of:

(http://home.hccnet.nl/piet.blaas/groot/ee20-c3-boven.jpg)

Hi,

I was given that kit, I believe that it was the EE20, probably around 1968. I wonder how many people on the forum were influenced by these kits. I seem to remember two kits, a base kit and an expansion kit.

I also had a Philips radio kit. This kit didn't use the springs, it had a grid of nuts an bolts molded into the bottom of the case.

That piece of wood sitting on top of your amp is going to cook it in very short order. I have my Yamaha amp sitting on an open shelf with excellent ventilation and it still gets very very warm.

It looks like it's two strips of wood at the front and back feet, rather than a full panel covering all the holes, so he should be ok.

HP 3326 dual oscillator - 13MHz can be either different phase or frequency.  A mere lightweight at 26kg of vintage iron, well mostly aluminium. Arrived from USA - one cracked foot. Works fine - bit of age softened plastic inside.
I am also a bit of a LED display fan.(The 'cool'  display tech of my youth).

What a beauty!
It must have cost a bit to get it shipped from the US.

It does indeed reminds of those kits.
My first electronic kit was this one, when I was something like 8

A 7S12 in a rather unusual configuration: S-2 Sampling head and S-52 pulse generator head.
Was sold as untested, didn't work and caused the scope mainframes supply to shut down. Simple fix: replace failed (shorted) cap.

DC Offset pot appears to not work, not yet investigated further. Otherwise fine.
Now I've got another problem: I don't have a GR-874 to something useful adaptor.

Probably a clone, because it didn't cost the usual > EUR 500, but just EUR 107,98 (http://cgi.ebay.de/322089434058). But after some work, it is running now with my Raspberry Pi and Python scripts, to communicate with my Fluke 8842A:

Also, since GPIB is not an open standard, no one can implement it without internal document. Prologix one has only limited implementation and is not yet bug free, and that's the known best unauthorized GPIB implementation.

GPIB is a standard, see here (https://en.wikipedia.org/wiki/IEEE-488). Of course, it costs like EUR 600 to buy the part 1 and part 2 standard documents from the IEC webstore, if you can't find them somewhere on the internet for free, but hardly a problem, if you plan to develop and sell a high cost device.

There are also cheap projects based on the Arduino for a GPIB adapter:

http://www.rudiswiki.de/wiki/GPIBtoUSB_Nano3 (http://www.rudiswiki.de/wiki/GPIBtoUSB_Nano3)

Of course, impossible to use it up to 8 Mbytes/s and maybe it lacks a lot of the standard, but might be sufficient to send some commands and read a voltage from a multimeter with low update rate. I would have bought this, because I don't need fast speed, but I need it for projects I plan to sell and for this I need just something that works and is proven. Don't want to waste time thinking about if the Arduino script is wrong or the voltage of my circuit is wrong :)

Only $5 including FedEx shipping. Looks like it actually came from Digikey (Thief River Falls). If I had paid for the shipping, I would probably be filing a claim against FedEx, the worst shipping company I have ever seen.

I knew it was coming and checked tracking late in the day. It showed it had been delivered, but I was home all day and knew it hadn't. I finally found it at the apartment office. Apparently since it was "no signature required" the driver just left it there instead of going another 500 feet and up a flight of steps to actually deliver it to my door.

Not a purchase, but I ran off on a rescue mission last night to save an old broken synthesiser...

Going to get it from the back of the station wagon in the cold light of morning, I wonder if I've made a terrible mistake. This thing is ridiculously huge. Quite possibly occupies as much volume as every other keyboard I own, combined.

And yes, that's an 88 note full size hammer action keyboard looking lost inside the outline of this complete monster.

I have not used it much so far, but I like it. Although I get a strange feeling that the 101 is of higher quality. Probably because of the smoother knob action.
Perhaps a teardown is in order to clear any suspicions of shenanigans

You can read about it in the May 1966 HP Journal (http://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1966-05.pdf).

I did a video of a partial repair and use fo the unit as well

These are nice, compact probes. Unscrewing the plastic cover can be useful for low inductance connections with minimal loop area. You can see them being used in some Mike's electric stuff and Bob Pease videos.

Think before you connect two (or three) triax connectors together. Connecting two driven guards together will not work well. Triax connections are not as standardized and plug and play as BNC.

Anyways:

Some rubber tips for my vacuum on my hakko hot air rework station

4 new tips for my hakko desoldering iron, 1.6 .8 .6 2.3

cleaning brushes for said tips

30 New tips for my hakko 907. Yes I'm going overboard but I just couldn't stop adding those damn T18's to my cart. Every chisel tip, most of the CF tips, a few normal bezel tips, a knife tip, some very pointy tips, plus some other misc tips.

Dual solder holder

Tip cleaner

Some liquid flux.

Hope I can order them soon because I'm excited to use them.. especially the rubber bits for my HAR vacuum.

OK, step away from the tip selection!!!  You don't need every chisel tip!  .8, 1.6, 2.4 and 3.2 mm will cover everything you need.  The straight pointy tips, lose them.  The curved pointy tips are good for smd.

Pomona makes good ones.  I have several of each of the BNC jack to banana plugs and the banana/binding post to BNC plug.  I also have one or two dual to lead assemblies, but only because they came with various evilBay purchases - those I haven't been that inclined to use.

The BNC/banana adapters see a lot of use, however.

As for the purpose, well, seems like a good way to get acquainted with GNU Radio and SDR beyond being a user. And if I had time I'd like to play with the FPGA as well, but, being realistic, it won't happen.

Turns out that it's much more than they said at the beginning. Someone has found out that you can enable two processor cores and you can actually extend the tuning range.

looks nice and compact, what did you pay for it?
and more importantly, is it worth it?

I got it from here: https://www.aliexpress.com/item/STM32-OLED-T12-A-T12-Soldering-Station-Oled-Digital-Portable-Soldering-Station-Automatic-Dormancy-Soldering-Iron/32823360298.html (https://www.aliexpress.com/item/STM32-OLED-T12-A-T12-Soldering-Station-Oled-Digital-Portable-Soldering-Station-Automatic-Dormancy-Soldering-Iron/32823360298.html)

It seems to be nice and it does get hot and will melt solder but i did not do a lot of testing.

Today I received my FG-100 DDS Function Generator. Taking Dave's advice, I took it apart before I turned it on. In the reviews Rubicon caps are supposedly used. In mine there are labels on the capacitors I can actually believe. One of the posts the screen is mounted on is not present. The teardown also revealed another cute detail: the silkscreen near the power button actually says ROWER, instead of POWER. Looking at photo's online, other boards actually got this right. Other labels also seem misspelled, different or absent. That surprises me, because it means someone either copied the model quite convincingly, save a few details. The screws that hold the case together actually came pre-stripped. Not too surprising, except for the fact that they were stripped in the wrong direction, so in the loosening direction rather than the fastening, and one screw has differently shaped head. To me, this suggests the screws may have been reused. I happened to have some hex socket bolts that are the same size and roughly the same length, so I replaced the lot. Even though this might all sound fairy negative, the construction is actually decent and feels pretty solid. The board looks soldered properly and clean. It feels and looks more solid than other cheap Chinese tools I have bought.

(https://gloimg.gbtcdn.com/gb/pdm-product-pic/Electronic/2017/04/28/goods-img/1502220433143223937.jpg)

Of course, none of that matters much. What counts is how the thing works. Unfortunately, my oscilloscope is on the fritz, but a quick check with my DMM shows the frequency being 1 Hz off consistently. That is good enough for my purposes.

It certainly isn't the most capable or impressive signal generator on the market, but it will do. For now, I'd rather spend my money on other tools. Until I grow the need for a more competent generator, this is actually a very neat and cheap little tool.

I got my metcal mx500 station yesterday, got it from ebay.

It came with a stand, a new handpiece, 3 used but working tips, and 2 new tips.
I also got the DS1 desoldering tool, a spool of good leaded kester solder and 100f spool of solderwick, which is also good quality it seems.
A pretty good deal i think.


What i love about the station is that its built like a tank; the amount of tips avaliable is very nice(sttc026 is awesome); tip to grip distance is very short aswell, even shorter than weller WMP handpiece, which i really like.

Also tested the DS1 desoldering gun at work, after giving it a proper clean. That thing just blew my mind.
Now i just need to get some kind of pressurized air supply at home, so i can use it. I was thinking about a high pressure bottle of air, that i could refill after emptying it, should work well in theory, since im not going to use it very often.

http://i.imgur.com/JE1gDVT.jpg (http://i.imgur.com/JE1gDVT.jpg)

The desoldering tool is still at work, i started making a holder for the gun since it didnt come with one, and i cant even use it at home anyway.
Also made a removable brass wool cover for the iron holder, should have probably made the hole a bit bigger ;D

I'd definitely say project boxes as neodymium magnets of that size are very heavy (the bin would be notably sagging at best).

Definitely project boxes, if those were magnets they would be covered with every bit of ferrous swarf from the area, plus the meter would be stuck to them as well, because of the steel parts in the batteries, the screws and other steel parts in there like the buzzer and the leads of the components.

There are visible seams on those two metal things, which leads me to conclude that they are project boxes.
If they were neodymium magnets;
They would be so heavy they would break the shelf.
They would bind together.
Every metal object in a radius would be attached to them.
There would be no seams.

That kit looks really interesting.  I've wanted to do their TI Precision Labs - Op Amp course for a while since I heard the Art Kay interview on the Amp Hour.  The board is $200 so it will be a little while.

I bought my Mac solely for OSX development, but I also want to have a backup Windows machine in case of a power loss or for mobile working.

fair enough!
it's a shame mac are so anal about VM-ing their OS.
I'd consider buying mac os to run in a VM if it were available...

I guess the other option is have a mac mini for the apple dev stuff? I know a few who did that, but depends on if you want to do iOS dev on the go?

Altium should work fine on a media centre PC. I did it a few years ago as a stop gap measure and it wasn't as bad as I was expecting.... It's not doing massive game style rendering even for its 3d view, or doing lots of crazy background realtime stuff... just needs basic screen drawing capabilities most of the time, and enough RAM to hold off too much swapfile usage (but again AD files are relatively small anyway)  then you just wait a bit longer when it performs the DRC or runs the outjob. :-)

When I took the dive into Mac land a few years ago for OS X and IOS development, I initially tried to use Fusion to do all my Windows stuff thinking it'd not be so bad. I gave up after a couple of days. One of the benefits of Fusion in those days was that it'd run you Bootcamp partition as a VM, thus saving having to have multiple copies of Windows. The problem was that it broke the copy protection in several software packages, many of which were dependent on a constant MAC address. Each time I flipped between runnng Windows natively in Bootcamp and then back as a VM, the MAC address changed, the software phones home, and things like backups and compilers stopped working.

For work, as well as the meaty dual Xeon desktop I built, for my laptop which is a 2012 Mac book pro retina, I now run 99% in native Windows as a large bootcamp partition, and only go into OS X sparingly when I have to test or develop something for OS X, or need to access the App store or provision something.

As a Windows PC, the various Macs I've purchased haven't been half bad. I gritted my teeth when I bought that MBPr, but I don't regret it as it's aged well, and I'd have to pay >$2.5k to get a marginally better performing unit for my needs.

Along the way I learned that there's no way reasonably to do IOS and OS X development without a proper Mac. Hackintoshes are also too much pain, you're fighting to get it working all the time, and bits of it frequently don't work unless you have exactly the right hardware.

Unless I needed to do OS X or IOS development now, nowadays I can no longer recommend most Macs as unlike those I purchased a few short years ago, they are not upgradeable which I find staggeringly bad from a company that bangs on about its green credentials.

From what I found on the net, looks to be a linear array type of probe. It's indicated as used for small and vascular stuff. The regular abdominal probe is the curved one. Thank the gods I didn't get the  "endo-cavity" probe.  :phew: That would have been awkward to test and play around with.

Well not today but recent, took me a bit to sort through the hamfest stuff but here goes.
Fluke 8050A pristine condition original everything complete with fresh nicads, sharp lcd, manual, test leads and rf probe.

Keithley 177 missing handle otherwise nice condition and very accurate.

Hickok 209A very clean with non butchered internals. Needs a full restoration, wax caps and the test leads and power cord are trashed.

BK precision 801, measures very accurately in MHz though nothing at all when set to kHz. It was cheap and now it is a project.

Pyramid PS-26K which as promised will put out alot of current BUT the meter does not show that if set to 15V and connected to 1 ohm load, not even its maximum rated current out 15A instead of 25, it drops the voltage to 11 volts. The panel meter does not appear to be reading the voltage and the specifications are bunk, if nothing else i can toy with it and make it better.

LG 1920x1080 24" monitor working for 10 bucks with the only catch being that it has been repaired by hobbyist before me. This makes the 5th monitor on my desktop, third HD one.

A small army footlocker, think milk crate, half full of old panel meters including some really nice ones not just generic this or that but purpose built. Those are always the prettiest.

4, 1-50 ohm 225W variable resistors.

1, 50 ohm 200W fixed resistor.

A literal shoe box full of wall warts.

4 large miscellaneous boxes bought for one item but have many useful items in them.

And when i got home from hamfest i spent what was left of my money on a very big bag of parts.  Misc. from ebay but from futerlec,
100, 74F00 because they were cheapest; 200, 14 pin IC sockets; 200, 16 pin IC sockets; 25, CD4029 counters; rest is also misc.

For those among you who might find it funny.  I got the display cord for the new monitor on ebay the day before they realized someone had botched a listing and that they were giving them away for free.

Can't wait to build this thing :D

EDIT: It's mainly for my band, but having access to som IEM and wireless mics always comes in handy when I do work as a live audio engineer too.

I bought 10 of these:

The seller even put together a qty 10 auction for me which is still up.

They look like the 3M with gold plating.  My only gripe is that they didn't come with the aluminum back to stick them all to.

Taking after FrankBuss's lead in this post here: https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase)!/msg1283454/#msg1283454

I decided to follow suit and buy a similar adaptor off eBay too. It arrived all ok, and I just tested it out with my HP 8924C using the supplied Agilent Interactive IO software, and it works as expected. I can query it and get a valid response. I also tested it on my HP 8901B modulation analyzer and it worked perfectly too - I must admit it was kinda neat interfacing to a piece of equipment designed and first manufactured in the 1970's, using a USB interface running on a relatively modern computer!

Next step is to get it all working with linux-gpib (like FrankBuss did) and using the Python bindings, write some code to automate some test procedures that I occasionally do.

...and also added to the cache of RF test gear is a few attenuators.

First up is a Weinschel branded unit that was purchased off eBay, it requires a heatsink to mount to (which I have but am yet to hook it up) when swept on a VNA it tested well and truly within spec. It fluctuated by about 0.7db over the entire 0-4GHz range. Comes with decent quality N female connectors as well (Mmmm, gold plated Beryllium. Yum.)

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=347148)


Next in the list is another Weinschel unit, this time it comes encapsulated in a heatsink, so it will work fine as is - again its a 20db unit, and it swept within about 0.9db from DC-4GHz as well!

..and because the ones rated at 100 watts heated up a little too quickly for my application, I splashed out on a 200 watt rated "BECEN" branded Chinese made unit as well. This one sits in from of my HP 8924C and 8901B to protect it from 100+ watt transmitters when they're being tuned/aligned. I prefer the external units as opposed to modifying my 8924C for Option 060 - especially considering the internal heatsink is about the size of a pack of cigarettes and can only handle 100 watts for 10 seconds or so!

Both of these also swept from 50 kilohertz to 4GHz and were within 0.7db!

Older 100W 30db eBay/Chinese unit:-

Nice, is this using the VISA framework? Then you might be able to use it from Windows and Python with something like this (https://github.com/python-ivi/python-ivi). But using it from a small Linux system like the Raspberry Pi has the advantage that you can do long measurements or build test jigs, without the need to run a PC all the time.

I see no reason why you could not run the same Python program with PyVISA-py on an SBC like a Raspberry Pi or BBB. PyVISA-py supports linux-gpib bindings in addition to more modern interfaces like USBTMC and VXI-11.

Something I have after for a while now, a Heathkit V-7AU valve voltmeter. Cant believe how hard it is to come across a good one of these. This one internally is like new and externally is just dirty but a good clean will restore it back to as near mint as it is possible to get. needing calibration and a small problem with the zero adjust top sort out as it is too touchy and breathing on it will cause needle to shoot halfway across the scale.

Luckily I have a couple of Pi Zeros lying around - the older non-wireless type - so I can dedicate one to the task, kinda like giving the instrument a dedicated interface.

I don't think the 8924C supports VISA, but I'm not really sure what VISA is and how it works. Modern test equipment certainly has come such a long way, with VISA, LXI, Ethernet and USB all included these days.

In any case I can just send the raw ASCII GPIB commands to the unit and request a response, so that's a start.

What does the VISA framework add?

Also, since I have two instruments with GPIB, I am tossing up whether or not to buy a second USB-GPIB adaptor or use a cable to put both devices on the one bus...

Decisions, decisions!
Title: Re: What did you buy today? Post your latest purchase!
Post by: FrankBuss on September 02, 2017, 11:13:22 pm
VISA is a specification for controlling instruments: https://en.wikipedia.org/wiki/Virtual_Instrument_Software_Architecture
I remember when I tried to use my SPD3303D power supply on Windows, I had to install the NI VISA libraries to use it. It specifies GPIB access as well, so could be possible that the Agilent drivers implements this API as well. But if you have a Raspberry Pi, better use this. Together with the ideas of the voltnuts platform, it is easy to implement custom measurement solutions with a web interface.
Title: Re: What did you buy today? Post your latest purchase!
Post by: alm on September 03, 2017, 07:41:12 am
The idea of VISA is that it abstracts  the physical interface to an instrument. You can switch between an RS-232, GPIB, USB or LAN connection by only changing the connection string, as opposed to calling different functions to read and write to it, or to trigger it. There are Python bindings (https://github.com/pyvisa/pyvisa) and even a pure Python backend (https://github.com/pyvisa/pyvisa-py) that you can use on any Linux platform and probably even Windows without installing the NI stuff.

The voltnuts platform seems to aim for as much device-specific code as possible, so I guess there is no place for such abstractions there.

No, it only as to support one of the interfaces (e.g. GPIB or RS-232) that your VISA implementation supports. The instrument can not tell if you called ibwrt (raw GPIB) or viWrite (VISA).

I have one and they work very well and there's lots of available nozzles for then. They are aren't as nice to use as an expensive unit due to the weight of the hand piece, but for occasional use it's great value for money.

Remember having a few of these in a workshop years ago and thinking they were great little instruments. Mint condition, and accuracy is reasonable.

Trends - like seeing a capacitor charge/discharge, without having to take note of a lot of numbers ... plus voltages (or currents, for that matter) changing too fast for a DMM to give meaningful readings.

.. Or for general sanity checks and small fluctuations or poor testlead connection, also parasitic mains voltages (low Z) can be double checked with these, many good uses. I would also claim that the ones (edit. just noticed that MICRONTA do have FET frontend. ...nice. :)  ) with amplified front end are great tools for getting general understanding of electricity, more so than scope and DMM. In the limits of the bandwidth of course.  Plus passive analog meter is great tool to get understanding of the measurement error world.

Also for precision biasing the analog needle is much much more expressive than what the flickering numbers are in the DMM display.

Unfortunately for a client, not for the workshop.  :(

Nice unit. I'd have hoped for more than one fan though. Not counting the tiny PSU fan of course which won't help much if the main fan fails. Unfortunately nowhere to mount a second one so not much to be done about it.  Would also have liked a dust filter. They supply a rather pointless front cover, and it would have cost no more to put a foam sheet in it. Makes a real difference to the state of the insides after a couple of years onsite.

I know. It's running for a while now. WiFi performance and coverage is really good.
I played around with the other for a bit, and had a few scenarios running pretty quickly:
- Dual radio WiFi bridge 5 GHz uplink, 2.4 Ghz Access-point.
- Selective VPN gateway, only a few selected clients will use the VPN as gateway, not all of them.
- Equal bandwidth sharing using queues.
Todo:
- Site-to-Site VPN, to use the same WAN IP and network in second house. (for server and iptv)
- Layer 2 Wireless bridge, for isp proprietary iptv boxes.

Unlimited possibilities! 10/10 would recommend. (if you know your OSI)

The device can measure the dose equivalent rate of gamma and beta particles in µSv/h. There are two measuring periods to select from (27-29 seconds and 270-280 seconds). The longer period is for more accurate readings. Besides the measuring mode there is also a surveillance mode with configurable alert threshold.

Since I did not find any information on the device here on the forums, expect tear down pictures and some more in-depth information coming soon :)

Edit: I posted the name in cyrillic unicode, but the forum software can not handle that - very disappointing. Did recognize the lack of supported chars before (accents et.al.). meh  :-//

Got this HP 3562A DSA from a university as "surplus"  in unknown condition.
had a bit of a rough shipment but, its built like a brick shit house and survived with only a slight dent..
1 lithium battery and one tantalum cap later its up and running.

looking at the chip date codes, it looks to be  about 28 years old and looks like no ones been inside it before.
here it is doing a noise floor test on a mic preamp.

Tin,
You are going to repair it, right?
At least, that's the idea...

MasterTech
Mhm, voltnut's approval was not wasted :) Now get two LTZs in those boys and off you go...

nctnico
3245A's are hidden gem of the voltnuttery. Mine saved me during tests/calibration checks many times. With LTZ pimp-up it's also very stable mid-term DCV source (<1ppm over 24hours easy). High AC resolution makes it handy for many of AC checks.
1:10 amp only sweetens the candy, however MasterTech got dual-channel versions instead.
Here's (https://xdevs.com/sl935_6221_DMT1/) quick example how 3245A can help to get lower noise resistance measurement together with 3458A, measuring 10Kohm. 3458A red line is regular direct connected 10Kohm, about 3 times noisier.

Hi,
Today I found a rare connector:

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=349560;image)

It came on a short length of PTFE cable.

I found the datasheet here:

http://www.milestek.com/descriptions/productspecs/10-06030-231.pdf (http://www.milestek.com/descriptions/productspecs/10-06030-231.pdf)

These are hard to find, because there are very few of them and also because they look like common BNC connectors from a distance.

They are used on SMU and semiconductor parameter analyzers.

Isn't that a triax connector? For very low noise measurements. Like the one Dave has on his Atto Amps vid, w/ the Keithley 617 Electrometer.

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=349562;image)

It is very similar. Just to add to the rarity of these connectors, there are several variations. The one on the Keithley 617 has two lugs, like a BNC. The HP 4155B has three lugs on the triax connector.

Re the 'triax' connector, I thought the 2 lug was the older version and less common (often old Keithley - Fluke gear) , the 3 lug is the more common version now. In another post, an eevblog postee gives this connector its proper name I think 'TRB' , but it is also commonly called by the name of a common manufacturer as well, I think 'Trompeter'.
Fitting one is a long drawn out exercise - especially as you don't want to get finger grease and other impurities in the joint.

You are correct.
If you look for the keywords Trompeter, TRB and TRIAX they are easier to find but still expensive.
I have now a small collection of 2 and 3 lug cables and connectors.
Only my older Keithley 614 takes the 2 lug version.
The Keithley 2450 SMU and many modern electrometers like the Keysight B2987A take the 3 log version TRIAX connectors.

>A grimey lathe I bought a couple years back cleaned up real well with White Spirits, amazing how much better it was than other solvents.

It will clean up OK. All rust is light surface, nothing serious. Everything nice and tight, almost no play. The only real bummer is that removable section of the bed, which is goneski. Has never been sighted. But if needed I can make a replacement.
What I can't make, is the GIANT faceplate that comes with it. One of several different size face plates included, plus extra 3-jaw chuck and some other stuff.
I bought it for the huge faceplate, which I need for a specific machining project.

>What's the make TH ?

Ha ha... Damn, I was looking at the manufacturer's plate today, but didn't take pics (because I'd already decided I love it) and now I've forgotten. A well known old Australian brand, I just can't think of it right now. Not Hafco, not Sheraton.

It was listed for $1300, I got it for $500.  Had hoped for $300 considering the bad presentation, but 'the poor widow', etc. Not sure if I'm an arsehole or a sucker.

Btw, in the past I found White Spirits are a nasty nerve poison, when absorbed through skin. Kerosene is much safer.

So, what was the price? Can't work it out from the listing. Looks like a nice machine.
There are a bunch of large CNC lathes listed in Sydney for $1. The "PLEASE take it away!" price. I didn't take one of those because a) too big, can't transport and haven't enough space, b) Learning curve/time, and can't be sure I could get one working. Just need to do one simple (but large) thing. Asap.

Still might buy one someday, if only to play with. First need to solve the space issue.
Title: Re: What did you buy today? Post your latest purchase!

About 500USD or 450€.
Space is getting smaller at my home too, but it's a rather tiny machine and I couldn't resist at that price and distance (about 30km from where I live). It should also fit trough a 95cm door (perhaps have to remove x-axis or servo for that), so I can put it inside rooms where larger machines don't fit in. Here's a picture with human for reference:

Cool, that's much smaller than I thought from the listing pics. Very cute. About Au$620.
In what way is it broken and are you going to do a repair thread on it?
Do you have any source links of information on those?
Wonder if they exist in Oz? A CNC mill is fairly high up on my want list, but I'd assumed they'd be too expensive.

Perhaps I'll do a repair thread, if it's an interesting failure. But if I'm lucky, it's only a couple of dried capacitors and/or dead batteries.

Here's the repair thread for my Maho 700, that I bought about a year ago.

https://www.mikrocontroller.net/topic/410520?goto=new#new (https://www.mikrocontroller.net/topic/410520?goto=new#new)
Almost took me a year to fix everything. Reverse engineered/redesigned in discrete parts a now obsolete and thereby expensive TCA280 and wrote an assembler for Siemens S5-010 SPS language because an EPROM had leaked in the PLC. Fortunately the source code for the PLC was included in the machine manual (good old times :) ) and I found the opcodes in the internet, so I was able to write (more like hack, my programming skills are horrible) an assember myself.

Cool, it looks a nice size machine and seems to have quite a few accessories included looking at the pic.
Missing the gap bed is normally no big deal unless the gap is huge and the carriage can't reach over it. It's only an issue when turning something mounted on the faceplate where you need to get closer to the headstock.

Things that are easy to overlook and leave behind are:
Chuck keys
Tailstock chuck (and key), dead and live centres, tooling and steadies. I see the tool post on a shelf and there should be the key for that too.

A unit of that size and condition costs to get home and clean up and as you didn't have any competition others also thought it was too dear @ 1300. Take real care shifting it, they're top heavy and real heavy. My guess for that unit will be ~1 tonne but surprisingly easy to move once it's on pipe rollers.

White Spirits is just low octane petrol......without all the nasty muck added to boost octane.
Tiger Moth planes and early tractors and cars ran on it.
It doesn't stir up the skin on your hands like modern petrols does.

To be entirely fair wood shavings as a rust preventative may not work however it does make sense in that the wood shavings soak up water to a limited degree. The problem with that logic comes when you consider that wood simply cannot soak up all of the water even if it did then you just have wet wood shavings sitting on metal and as you said with no oil it is highly ineffective.
Title: Re: What did you buy today? Post your latest purchase!
Post by: TerraHertz on September 11, 2017, 04:01:47 am
The problem with dry wood shavings on oiled steel, is they soak up the oil. Leaving the metal unprotected - and in contact with wood, that tends to attract moisture too. As well as being a bit acidic sometimes.

I'll have more pics tomorrow, hopefully. Arranged to pick up all the accessories then, lighten the machine where possible, measure for transport, etc. And if I can remember this time, will be able to tell the brand and model number, instead of looking like a fool.
And btw, I've already been told to NOT remove the headstock.

Tautech thanks for those links. I should send that guy pics of my old Sheraton model A lathe, since it seems to be a pretty early one, and he asks for them.

I'll have more pics tomorrow, hopefully. Arranged to pick up all the accessories then, lighten the machine where possible, measure for transport, etc. And if I can remember this time, will be able to tell the brand and model number, instead of looking like a fool.
And btw, I've already been told to NOT remove the headstock.

Tautech thanks for those links. I should send that guy pics of my old Sheraton model A lathe, since it seems to be a pretty early one, and he asks for them.

I knew that about wood shavings though, in my opinion, it is definitely interesting to hear both sides even if one side is in error. That being why i said anything about the subject of wood shavings on metal to begin with.

Leave the tailstock and carriage on too and secure them at the far end of the bed as it helps balance.  ;)
Yep, send Tony an email, he's fanatical about this sort of gear and when I sent pics of my Harrison 12 he hadn't seen one optioned like it.  ;D
I lifted mine onto a tandem trailer, slung under a forklift....yes under as there's no risk of it toppling over and at home had a tractor with a loader that could lift it and maneuver it into the shed where just a short travel on rollers had it into position.  :phew:
Good luck, hope it goes without incident.

There are a bunch of large CNC lathes listed in Sydney for $1. The "PLEASE take it away!" price.

I had to look.  Wasn't hard to find - but the sizes were an order of magnitude greater than the space I have available.  Not small ... and certainly overkill for anything I could ever imagine.


Yeah ... Big.

Finally today my new lenses for my Leica A60S stereomicroscope arrived  :-+

I have this microscope for over four years now and I love it except one thing: the minimum zoom is 5x which results in a field of view of around 46 mm and the height to the table was okish with aprox. 10cm.
The main issue that I faced was that when I started to solder, I often had to look away from the microscope in order to move the tip in the aproximate area.
So the actually minimum zoom was just too large for my personal taste.
Now there was no solution till I stumbled upon this shop:

1) Leica A60 Objective Lens Adapter
https://www.engraver.com/leica-a60-objective-lens-adapter/ (https://www.engraver.com/leica-a60-objective-lens-adapter/)

2) Leica 0.63 Objective Lens 10446319
https://www.engraver.com/leica-0-63-objective-lens/ (https://www.engraver.com/leica-0-63-objective-lens/)

I ordered directly from Leica which made it more expensive but that is also where the microscope came from but at first they did not know this even existed   ;D
In the brochures of the A60 it is also not mentioned.

Anyway today they arrived and now I have a field of view in the minimum zoom of a stunning 77mm (around 3x) and the height to the table to the ledlight is now 14 cm.
I am very happy with the result, this makes smd soldering way easier and TH soldering also an option (my eyesight is deteriorating at age so this is an extra bonus).

Only negative is the price (1/5th of the price of the microscope) and the max zoom has ofcourse decreased proportionately from 30x (4,6mm FOV) to 18x (12,6mm FOV).
The latter is not a big problem, if really needed I can always unscrew the adapter+lens and have my original settings back in a minute.

Today I brought this HP3466A bench meter on Ebay, it was a bit scruffy and had a broken handle, no test leads or manual and the seller said that they had powered it up and it lit up but could not test it further. I made an offer way below his asking price and was somewhat surprised when he accepted it.

I got it home and switched it on plugged in some meter leads and the "b" segment of the last digit was not working, so off came the lid and there was another surprise waiting for me, it actually had the battery option fitted and a quick voltage measurement showed that it a small charge in it so was hopefully working and only wanted charging? I cleaned up the contacts that I could see with switch cleaner, undid and remade any plug and socket connections and powered it up, yep, "b" segment was working.

I ran through some spot checks on known currents, resistances and voltages and I had another surprise, it was in calibration. I glued the handle back together again and left it to set, cleaned up the meter and removed a ton of old calibration stickers, the newest one was 2002 and left the battery on charge. Later I refitted the handle and disconnected the line and the meter was running on battery power, so now not only did I have yet another bench meter but also another DMM portable meter. so it really was a great bargain for me  :-+

I was wondering: do people here actually make it a habit to buy old equipment for multiple thousands of dollars? Or are those just the numbers attached to eBay listings that do not get snapped up, with the actual prices being much more benign? I understand that it's a serious hobby or even lifestyle for some, but even then the cost seems prohibitive for most.
Title: Re: What did you buy today? Post your latest purchase!
Post by: bitseeker on September 12, 2017, 09:43:45 pm
Well, it depends. If the thing isn't worth the asking price, then it's going to sit on eBay. There's no shortage of such opportunistic listings. So, they aren't an indication of what people actually pay for equipment.

Personally, thousands of dollars for a piece of old equipment is outside my budget and risk tolerance level.

Definitely.  :-+

Check the Completed Listings box on the left-hand side to see the actual selling prices.  ;) Of course, there are the occasional idiots that buy at some ridiculously high price. Do note some have been repaired/restored & calibrated by the seller, which will go for more (they usually offer an actual warranty as well).

It also depends on the item, asking price, usual price,  known issues / faults etc. I paid multiple thousand type sums for an "As is" 3458, with the RAM warning. It went well, ultimately saving me  several thousand dollars - but the risk was not small. The history of the dealer, photos, and the type of instrument also come into the equation.
I am not good at microprocessors, especially 1980s types - so I avoid items in which that could be a significant issue.

Note that for sold listings with Buy It Now and Best Offer enabled, eBay's displayed price (at least on the US site) is the BIN price. The actual amount paid may have been less.

Yeah, the 3458 is what prompted me to ask the question. I can't really imagine that many people being prepared to shell out more than 3000 dollars on second hand equipment, no matter how good the specifications may be, especially if I take any WAF into consideration. Yet it seems to be fairly common here. Sure, this would be the one place for it to be common, but still. Of course, a multimeter is just a start and at that rate, your garage will be stuffed with gear worth more that your house in no time.

I *generally* tend to limit evilBay purchases to under $200, with most falling in the sub $125 shipped range.  Occasionally I'll go over that, into the 5-600 range, but only for rather rare and/or very desirable (IMO) things.  I've found that patience is definitely a virtue on the 'bay.

Well, what I didn't buy today, is that lathe I mentioned. Dammit.

Despite having paid a $200 deposit, having a signed agreement of sale and price, and the remainder of the cash in my pocket while trying to arrange a meeting to pay him and start collecting the gear, today the seller back-slid.
I can only assume he decided to accept a higher offer. It's now showing as 'sold'. Though he lied about it to my face, and made feeble excuses.
He did return the deposit, but arranged the meeting to do that on false pretext.

Thanks for the sympathy everyone.
It was a bad day. First the lathe-guy arranges for me to go there, supposedly to pick up the accessories, then surprises me by handing back the deposit then driving off with nothing sensible to say for himself. So, no lathe.
Then my son leaves for overseas again (Panama), this time likely for a long while. He's set himself up as an Amazon seller, doing well, and decided he likes the traveling life. Then while driving him to the airport, while stopped on the M5 due to slow traffic, a semi-trailer rolls gently but irresistibly into the back of our car. Driver distracted, took foot off brake. Minimal damage, but a nuisance.

Oh well. At least in anticipation of the lathe I'd moved a lot of accidentally accumulated junk out of my 'forge shed' to make space for it. So it's now feasible to get that whole stalled building project back on track. And yes, there will be other lathes. Though I rather suspect I'll be lucky to find another with a set of faceplates of all sizes up to huge. That I can afford.

There's no 'deadline' as such. Just a vacuum system project that was stalled for years due to lack of some required (very expensive if bought) parts, that I now have. So now I'm eager to proceed.

Measures a 1degree phase difference & gives credible voltage readings as a bonus. Well pleased EXCEPT I am supposed to be making space not buying interesting but relatively pointless toys. If only I had a bigger workshop!

I got a Testo 830-T2 (https://www.testo.com/en/testo-830-t2/p/0560-8312) IR thermometer today.
It has 12:1 optics with dual laser indicator for the measurement area and K-Type probes can directly be connected at the bottom of the "pistol grip".
It has some weight to it that does inspire confidence to be decently built for the price, the housing is only ABS and the display + back-light are not be considered top notch though.

The device can be set to sound an alarm if the measured temperature leaves a defined threshold. Also, the emissivity (https://en.wikipedia.org/wiki/Emissivity) [epsilon] can be pre-selected from 0.10 to 1.00 in 0.01 increments in IR mode.
Update rate is 0.5 seconds, so it can be used for slow sweep scanning.

That is how human perception and psychology works :)
There are a lot of scientific studies that try to find out how we perceive values like "quality" and what way these are connected to something like muscle memory and learning (for example estimating the density of things by touch).

That's OK. At least two bench meters is a good thing to have. The curved "bar" graph is interesting. I haven't seen that before. Otherwise, it looks like the innards of a handheld living in a bench enclosure. When you get it, have a look inside to see if that's what they did.

Haha 2 bench meters?, make that 4 now, along with 4 handheld digitals, 4 analogs and a valve voltmeter to boot. I'll certainly look inside it when I get it, I always take a peek inside to see if anyone has been playing around inside before.

I don't think it is a handheld stuffed into a bench case, but it could be. What attracted me to it was the MIN/MAX feature, could be useful if checking a suspect power supply for fluctuations etc., it certainly isn't upto the standards of my Philips PM 2521 or the HP 3466A, the latter even has gold plated tracks on the PCB and looks mint inside. Only issue is the the lead acid battery has seen better days so I have sourced a suitable replacement and just need to extend the leads to it and provide some extra insulation  around the negative terminal to prevent it shorting on the metalwork bracketry that holds it in place as the terminal arrangements are different to the original.

@ Bendba
Because it is my current potato mill!  ;D

Apart that being said by AF6LJ (which is totally true) i need that instrument for a redundant power supply (or-ing) that i am designing and the evaluation's board manufacturer of the IC that i am testing states in the datasheet that i need a current probe for proper-full testing.Who am i to say no?  :D

The funny thing is that i purchased the 6302 probe from another ebay user and the TM501 PSU from another ebay user.A lot of reading to be made because the PSU dates from 1985 or so and even though the seller listed the PSU as working,i think that the electrolytic capacitors might have another opinion.A new adventure just hit the bench.

I hope that it is a solder burn but I really have my doubts, I would not expect a soldering iron if it came into contact with the plastic button to leave the plastic as clean and shiny as it is or to cause burn marks on the fascia like that, especially over the top of an apparently untouched button. It bears the resemblance of a building that has had flames / extreme heat escaping from the top of window frames and scorching the building fabric above the windows.

I know, I need help but I just bought another 2nd hand bench meter on Ebay, is was a Buy it Now or offer, so I made an offer and again I was surprisingly accepted. I figured that the price I offered, the leads that came with it would cost that much on their own to buy so was worthwhile gamble.

That's OK. At least two bench meters is a good thing to have. The curved "bar" graph is interesting. I haven't seen that before. Otherwise, it looks like the innards of a handheld living in a bench enclosure. When you get it, have a look inside to see if that's what they did.
You hit the nail right on the head here. It does however seem to be well made, it has 2 x 600v Bussman quick blow HRC fuses fitted. It has 6 AA cells and a mains power unit and surprisingly the AA cells are not rechargeable. Checked the manual and its correct, so the units simply has a AC mains detection sensor and in the event of no line supply being present, switches over to Alkaline cells, an opportunity lost.  I'll take a few pics and post here later of the internals       
Title: Re: What did you buy today? Post your latest purchase!
Post by: bitseeker on September 18, 2017, 05:56:12 pm
Yeah, nothing wrong with having innards from a handheld. It may be more robust as a result. The backup battery power certainly is a benefit derived from its handheld roots. Although having the batteries be rechargeable would have been better, that'd require more development work. Could be a fun project, though.

Regarding photos, if this meter hasn't been covered on the forums before, start a thread for it for others who may be interested, already have one, or need to fix one.

Post by: Specmaster on September 18, 2017, 07:35:23 pm
My HP 3466A meter has battery backup which performs in the same fashion and the switch over on both is seamless but the HP does employ a sealed lead acid battery so has a built in charger as part of the auto changeover circuit. I just have replaced the battery in that as it only lasted 10 minutes on batteries. I couldn't find a direct replacement battery of 6V 2.5Ah so I used a 2.8Ah one, slightly smaller in dimensions so needed some packing to keep it in the retaining bracket and battery leads had to be extended. It now lasts for about 8 full hours, nice.

I'll open a thread in the Test Gear section and post the photos of the Isotech there.

In the meantime, I purchased today these two radios, HMV Diplomat, superior sound to a Hacker, and also a Vega Selena 215 radio.

An EPS-301 Electrophoresis PSU.  5 - 300V out at 10 - 400mA (80W max), with constant voltage / constant current and 1V/1mA settability.

Unlike the rest of the range and most other electrophoresis PSUs it has a fully floating output, rather that being symetrical around ground. It also has no ground leakage or zero load detection, so it should work just fine as a HV bench supply.  I doubt I'll be needing the timer function but that can be turned off. From the limited voltage ranges on the mains input selector, it is linear rather than SMPS.

From the images it appears to power up and display ok so hopefully it will work on arrival, or be easily fixable. Worst case the seller has a very good returns policy.

All for the sum of £26 including postage, no other bids.  :)

voltmeters seem to be a little addictive to me, I was a little undetermined in which board to place my first post.

The TEA board (I'm reading regularly) could have been the right board as well -because I also own a HP 3325B, a Philips PM 6680 and a PM 6685 Counter together with GPSDO, Rubidium Oscillator and several OXCOs (time-nuttery ahead?  :palm: )
I decided against the TEA board because I've already sold a classic & cool testgear without really regretting it (ok, because a HP 3456A succeeded it  ;D ) :

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=353567)

Perhaps I am not completely lost to TEA..    :scared:

Ok back ontopic:
I received my third classic HP 3456A a few days ago and its completely functional though not cleaned up yet.
It's of the last generation with rubber keys. I like those "newest" of the 3456A's most because no service notes apply to them.  :-+
I got it for 75US$ plus 96US$ shipping and ca. 30US$ customs. Not a real score for those living in the US, but over here in germany these machines are quite rare and the last version with rubber keys is also rare in the us:

By the way:
Does anybody know anything about HP 3456A's with a blue front?:

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=353571)

This was my first HP 3456A and it's one of the 2512A... generation the last one with classic keys.

Cheap gadget - batteries not included :-)

Edit: I just calmed down after laughing at this thing. They have BENT the Zif socket lever such that when the socket is open ready to insert a chip - the lever is in the way and it's really difficult to get the chip into the socket! LOL! I'm sure it's _supposed_ to be this way because when the socket is locked it needs the bend as even with the cut-out in the case there would not be room for the lever to lock otherwise. You've got to be kidding me!

Picked up an Agilent 53181A with Option 010 (HS Oven) for relatively cheap on Fleabay. Excellent condition and fully working, bumpers included but no handbook. The VFD is bright and evenly lit. I've heard there are Clones of the 3GHz Option 030 available somewhere. Can anyone point me to the user/site where I can get one? I'd like to add the 2nd channel (at a reasonable price).

Not getting married.

Or no longer being married.  SWMBO met someone at work that she liked better and punched out a few years ago.  Thankfully no kids were involved, and the cats don't need college funds.

It will certainly cut it - might leave one of the pieces a bit bent though! I use the old 'score both sides with a box cutter and snap' method.

I ordered a "YSUMA01-341A" CH341A USBtoi2c/spi/uart dongle. 
I am on Linux so I figure this will be a learning experience. It was quite cheap considering all the hardware represented by those protocols but I will be surprised if I can do much with it because it seems fairly sparse in software support.

There is a Linux kernel driver for it now, though. Other dev boards to do similar things are much more expensive.

--UPDATE: I've found a bunch more software on github..as well as a 6 MB archive of software for it in an Amazon comment post.

I'm not sure about that exact board, but I have connected other CH341 based boards to SuSE Linux and they were immediately recognised and ready to go. I don't remember having to pop the hood and start compiling/installing manually.

A tip from someone who has done this mod a few times before: Don't put too much pressure on the difuser when you let the LOCA set. If the difuser is not perfectly flat (due to the metal frame around the LCD) it will start peeling away from the screen after a few days and the result is less than optimal.

I want to use it with a 14-bit DAC (AD7535BQ) to build a precise constant current source based on the design of Dr. Frank's DIY constant current source. If it is working well, I'll do a small batch of another five units.

I'd agree - they're handy things! Good for not scratching my desk, and it's nice and soft for working with delicate items. Easy to wash when it gets dirty, and seems fairly heat resistant.

Anyone think this used power supply was worth $20? It's a piece of Radio Shack history, if that makes a difference. The store I stopped in today is days from closing forever, so they're selling EVERYTHING. They had a whole table of equipment that they actually used for repairing electronics! I don't even know what some of the stuff was, and everything besides the power supply was $100 or more. Assuming it works I think I did ok.  I like the volt range switch much better than the cheapie I got on eBay a few months back.(https://uploads.tapatalk-cdn.com/20170926/e690e82e13b69f13d008da4d991ef4d0.jpg)

$20 is good if it's working well. It's a bit different than the typical clone that you see all over the usual places. The voltage "range" switch looks like it's a combination of a set of fixed voltages (bypasses the coarse and fine voltage knobs) for convenience and a variable setting (0-15V) that enables the coarse and fine voltage knobs. An interesting feature variation to this style of supply.

I want to get a little more use out of it before I post any kind of report. But it works, it doesn't smell (that was my main worry)  and its been useful. And it was really a good deal for what I paid for it. ($45)

I had some DealExtreme credits, so for shits and giggles I ordered some LED ceiling lights. I wanted to replace our halogen bulbs, but I couldn't find any modules with the same hole size, except these ones on DealExtreme (http://www.dx.com/p/youoklight-3w-warm-white-led-downlight-ceiling-lamps-ac85-265v-6pcs-469459).

(https://i.imgur.com/oGNcf8M.jpg)
Yep, looks like a good amount of propaganda on the box. They actually look quite nice. It's all (paper thin) aluminium. They weigh almost nothing, the entire package (6 units) is 360 gram according to DX.


(https://i.imgur.com/e7b7BVx.jpg)
Pinnacle of engineering, this separate LED driver. Notice the fake screw heads. Literally no attempt was made to hold the wires or the circuit board in place. I know where these modules will go, and it won't be my ceiling.


(https://i.imgur.com/CvrZuEL.jpg)
Dark Energy. Interesting name for an incendiary device.


(https://i.imgur.com/LKP6NBQ.jpg)
Chip is a BP9021a (http://www.bpsemi.com/uploads/file/20161124171900_815.pdf). Interesting to see how little external components it needs. Note the fusible trace on the mains live.


(https://i.imgur.com/65FEYqm.jpg)
The LED board itself, just 6x 0.5W emitters. The housing works reasonably well as a heatsink.


Those drivers are obviously landfill material, but the rest looks ok. If the LEDs turn out to be shit it should be easy enough to wire a new emitter in.

I looked on eBay too. They all seem to be Chinese cheapies. The one at Rat Shack may be of higher quality. I didn't get to stop there today like I wanted to. I was gonna show them the eBay listings that were $75 brand new and offer them $40. Sadly that store will likely be gone long before I'm in that area again.

Nice! Just got 6 old broken in some way PCs for free. I can start getting some desoldering practice.

I'm estimating that there are several hundred electrolytic caps. Considering I still haven't ordered any cap, I'm going to save them. Might be useful when I play with my first circuits.

As a rule of thumb, how many millijoules can I short with a screwdriver without damaging the caps?
I know that all these caps are most likely already completely discharged, and I even make sure with my multimeter, but i'm wondering about the general case.

General case,don't use a screwdriver use a resistor.

Bought a Feeltech FY6600S function generator since I wanted to play around with some ultrasonic disc transducers (which are still slowly making their way here from China). From a Chinese Ebay seller selling it from a Frankfurt warehouse for a really decent price, which since customs in my country is a bit of a bitch clinched it. Haven't done much with it yet, but I know someone asked for a pic from the inside in another thread so for the moment here seems as good a place as any.

Numbers erased from the ICs, but the DACs are likely overclocked DAC904s and the buffers I guess OPA690s (since that's what they use on Chinese DAC904 modules). Probably going to glue in a 15 Euro isolation transformer from Conrad.

I want it bad!  They do need to decide on a consistent style though.  I am not a fan of the keypad - not that I have used one to know.  But looking at their new loads, they have gone for a more conventional pad, so maybe they will do the same when they come to the next PSU version??  I still want it though!!

Anyone think this used power supply was worth $20? It's a piece of Radio Shack history, if that makes a difference. The store I stopped in today is days from closing forever, so they're selling EVERYTHING. They had a whole table of equipment that they actually used for repairing electronics! I don't even know what some of the stuff was, and everything besides the power supply was $100 or more. Assuming it works I think I did ok.  I like the volt range switch much better than the cheapie I got on eBay a few months back.(https://uploads.tapatalk-cdn.com/20170926/e690e82e13b69f13d008da4d991ef4d0.jpg)

The corner bumps on the front aren't even big enough, the banana plugs bump the wall first. They should have used the isolated banana plugs, and provide a bag of these.

OK but they are limited to 2A at 15v, I find the 5A at 30vdc versions are better though but cost about double the price. Many of the better old transistor radios need 18v to power them. Never had the need to use anywhere near 5A yet but the increased headroom is nice, runs cooler and means if it has a fan, it will be quieter in operation and that is a real bonus.

I bought a Astrolux S1. Its a really nice flashlight. The videos I saw about it didnt lie. Since I discovered minerals as a new hobby, next year I want to go in the mountains with a collectors licence and hopefully find some and I tought a good flashlight might come in handy.
I also got myself some decent USB to Micro USB cables that can carry more current. My old cables had quite some voltage drop.

What is the best thing to do on ebay when a package that was being shipped to you (alleged to be a Uni-T UT210E)

is delivered to the wrong address and likely was part of a scam? How to handle it? Ive sent a message to the seller telling them the package went to the wrong address and tried to figure out how to bring in ebay customer service but it appears that even though it was delivered to the wrong address they seem to want me to wait until the date I am supposed to receive it by.. which isnt acceptable. The seller seems to have gotten a few other complaints of a similar nature recently.

About all you can do is keep contacting the seller via Ebay and also keep contacting Ebay via their dispute channel. That way after the due delivery date has been and gone, they cannot claim that it is too late to raise a claim because the email trail is there to prove that you flagged it up earlier and that they told you to wait.

Keep copies of the emails to and fro as well, just as insurance should you need it.

Personally I've found my powered vacuum desoldering station cleans up Pads (SMD & TH) far better than wick ever could. I just add a little fresh solder and then vacuum it up - this leaves the pad with a super flat and shiny tinned surface which is ready for a new component.

Dark Energy. Interesting name for an incendiary device.

Ran into these inside some LED lighting just a few days ago... Needless to say, they didn't end up on my ceiling either!

The controller was just left hanging loose inside the light fixture, surrounded with pointy metal pieces just waiting to puncture the thin tape it was wrapped with. That and the far too thin wire for mains AC at 15 amps.

It's a shame since the light fixture itself is quite nice.

I bought a DHT22 temperature and humidity sensor. They are a bit more expensive than the DHT sensors (about EUR 3 on eBay compared to EUR 1, and $9.95 at Adafruit  :o), but the datasheet claims 0.5°C and 2% RH accuracy. I'm using it with this (http://arduino.cc/playground/Main/DHTLib) library. Glued on the inside of my formicarium:

I like how they also routed the mains next to the solder pads for the output. I wonder how many come shipped with the wires soldered to the wrong pad.  :-BROKE

I do have some braid left (excellent stuff made by M G Chemicals) but I'm getting through it way too fast and it's fairly expensive to buy. If all I need braid for in future is wiping pads off then that's fine.

Bit worried that the new version of the 474A+ is not as good as the original, now has a single ended 12V DC pump (the old one was dual and 250v AC), and the pump current passes through the gun back to the pump itself. Also some other neat features are missing. Oh well, it can be modded apparently.

The wiring is the mains fuse, instead of that expensive fuse, or the even more expensive fusible resistor, they instead combined all 3 into the connection wire. high resistance as inrush limiting, plus the wire is a fuse at the same time.

@Frankbuss, hope you put in some sanity checking on the controller, as the corrosive gases the ants give off will fail that sensor quite quickly, and hopefully the failure will not result in cooking the inhabitants to death as well. Here ants do not need any sort of control for them to be happy, they will do it quite well by themselves, and the larger ones will build impressive mounds as well in doing so, and then you get to the largest social insects around, termites.

The nest covers the heating mat about 10% at one side where the sensor is and if it gets to cold or too hot, I change the position over the heating mat manually, but it is quite stable at the moment. I don't think they will harm the sensors (they are only little 2 mm ants and I closed the bigger holes in the sensor with hot glue), but maybe a good idea to add another encapsulated IC sensor for the temperature for redundancy. Usually this species lives in South Africa, so they need some heat here in cold Europe. Without it they would die fast, no worries about invasive species, in case they manage to escape.

Next would be a regulator circuit for the mains powered heating mat. This would be interesting, because I've never done mains switching before. Will post schematics etc. in another thread before powering it up to avoid electrocuting me or the ants. Or maybe I do it the easy way and just hack the remote of a cheap RF controlled mains switch.

Well, they do love lectronics, as the large number of nests i have removed from gate motors attests to, and they secrete formic acid as a part of living, thus corrode copper traces away. The largest supplier of gate automation, Centurion, had to make all the sensors in the gates ant proof, which meant fitting them in nearly fully sealed boxes, with only the connector pins showing, and also make the electronics more or less ant unfriendly. Generally opening any gate motor here you will find a lot of white insecticide powder all over the inside, and lots of dead ants as well. Ants, geckos and battery thieves are the most common cause of gate failure aside from brute force to break in.

Think I do not need an ant farm, there are at least a dozen within 20m of me at the moment outdoors, the ones indoors kind of did not like the yummy meals I gave them, in the nice green diner it came in. just have to sprinkle more borax around, summer and cockroach main season is all about to happen, and I want to keep the big ones out of sight unless they are on their backs and kicking. Mosquito season as well, and I am the type that they love, need to buy more citronella oil for the lamp.

Sounds like fun :) In Germany ants are not that often. Found once some in the woods: https://goo.gl/photos/Xd2BzshRVVme1f9L8

but they were on the list of endangered species (they are probably Formica polyctena), so I couldn't take some for my ant farm, and they need winter rest as well, which would be boring.

I wanted to start a formicarium, but I read that you have to either find an ant queen, which is difficult (especially since my biology is worse than my electronics), or buy one which is no fun.

I wished there was something in between in terms of difficulty, like finding some really big ant and convincing her she was destined to be the queen or something.

Your profile says you live in Antarctica. I guess it is difficult to find ants there. Maybe Sean could send you some, but would require very good packaging for a shipment from South Africa to Antarctica and I'm not sure about customs :-DD

In case you live somewhere different in the world with higher population, usually there are local ant keeper groups and you might get a queen for free or little money and tips how to keep them.

I am glad the ants have finally left my home.
They can find the kitchen from any extreme small cavity available and then one day you see a procession, a traffic jam of ants going both ways to something they can eat, often opening paper bags and or plastick bags to get to it. Then under the backdoor they dug through the concrete and cement an opening to inside the house under the doorstep where they started to lay their eggs, but unfortunately also all my hometheater wiring was there  :scared:
Three years ago i built three meters extra livingroom and outside poored concrete to lay the terrace stones in,  now they are gone at least they now moved just outside the terrace. That is ok for me. I can not believe they are endangered since they survived since the dinosaurs, I think they will outlive humans as a species.

Here just wait for the spring rains, and there will be queens a plenty, along with the males. Though the more numerous are the termites, where the number of queens and males is in the millions per square kilometer, and where you can have the entire windscreen splattered with the remains in a short drive. The dogs love this snack fest, along with just about every other predator and every bird as well. The birds get so full they cannot fly easily. If you have fish you do not need to buy them food for that day or two, just from the ones that fly indoors, and if it is a pond they will stop eating eventually when they are totally sated.

Only indirectly electronics related but I just bought a Husqvarna 562xp chainsaw with a 24" bar.  My trusty Stihl 250 is just not up to the task of bucking out some of the larger trees down on my property.

I almost bought the next model down - the "555" - which has a nice electronics meme model number - but in the end decided to put up another $100 and get a professional saw.

I've been hesitant to buy one of these newer saws with electronically tuned carbs. The Husky "Autotune" and Stihl "M-tronic" systems have been out for a few years now. The long term reliability of electronics is a virbrating, sawdust, dirt, oil and gas exposed saw is suspect IMO. We'll see.

It would be nice if they made the Autotune software available and usable for non-dealers to use the diagnostics and and do firmware updates etc... >:(

Would love to hear if anyone has done any tinkering with these.  I'm sure someone on this forum has the skills to hack into the electronics on these.

I used to turn spanners on saws for a living some decades ago. That local dealer is still in existence and I have good relations with the son where we discuss the new features quite often over a beer.  :) We were the 2nd largest Husky dealer in NZ. Been a little time since we had a good chat so I'll get onto finding the latest stuff on them. TBH I haven't heard anything bad about them but the industry's changed heaps in the last decade or two where there are many less crosscutters now as most felling is done with feller/bunchers and processor machines these days. Even on bloody steep country where they are secured by rope to anchors at the top of the steep faces.  :scared:

Thanks tautech. Any inside info would be welcome.

Here in the Pacific NW of the US.  Chainsaws still dominate for felling trees - even the large logging operations.

But the majority of saws are in use by people putting up firewood.  For me it means bucking the downed trees on my property do I can then split the rounds for firewood.

There's quite a bit online about the new electronically controlled chainsaw carb systems. They've been out for a few years now and I think most of the bugs have been worked out.  For me it's just a matter of wanting that "end user control" and ability to fix my own tools if needed.  There's a Husky dealer in town here but if they ever go belly up I'll have no way to install firmware on a new carb if needed (replacement carbs come without firmware installed).

Yeah I cut ~10m3/year so I get to use my saws (all Husky) a bit and do some problem tree work on the side  ;) when I've got time. Mine range from 53 to 120cc plus a 88cc unit for each of my boys.....all old school manual carb units. Keeping them all going is like riding a bike...once learnt, never forgotten.  :phew:

I'd love one of the new one handled pro units for up-tree work but I'm not sure how much longer I want to do that monkey business rather than let the young and fit guys do it.

PS. The biggest I ever felled was ~7 foot through and nearly all my 36" 3120XP can handle. We (boys and I) spent days blocking it up.

FWIW, I find MG Chemicals to be really good stuff.  :-+ Specifically, their 835 RA liquid formulation (50% solids according to its specs.).  ;)

That said, despite it's available in small quantities (i.e. 100ml bottles +), MG Chemicals' 835 (RA) isn't my favorite. t's readily available in small quantities and it works  very well IME.  My favorites are from Kester, but past disposable pens, which are exceptionally expensive  for the amount/volume, it's quite expensive. Specifically, Kester's smallest size past disposable pens = 1 gal. (and goes up quickly from there; 1 gal. bottles/jugs to drums in short order). Regarding  RA = 1544, RMA = 186 or 186-18 (latter = lower solids @ 18%, which is easier to clean).

In terms of paste/gel, I'm partial to Kester RF-741 (http://www.kester.com/products/product/rf741-rework-flux) (comes in 30g syringe tubes; just need a plunger or dispensing gun to use it).

Do note this is from a US/CAN perspective (pricing & availability).

It is good, I use it but it does leave a nasty sticky residue that really takes a lot of cleaning with IPA unless someone knows a better way of cleaning it up. I know it says "No clean" but it doesnt look nice if you leave it behind afterwards and just attracts dust etc to stick to it which cannot be a good thing can it.

Agreed. I would make the effort to remove any residue regardless even if only for aesthetic reasons.

I do have an issue with these syringe applicators, not too easy to control the flow. I'll have to make/buy some sort of dispensing device which offers more precision. Do you know if this stuff reacts with any metals or seal materials directly? I could use stainless steel to make a reservoir and perhaps Viton or PTFE seals in a pump mechanism. There must be a commercial applicator but I'm guessing it would be a prohibitive price for hobby use..

I don't know about that, it is dispensed via a stainless steel tube so that is OK. The label states serious eye injury will result from getting in your eyes and also suggests that it is corrosive on skin. I suppose that once soldered with, the corrosive element is used up or neutralised by the reaction of heat and solder? I notice that a lot of the Youtube content creators use a flux that is almost liquid, this one is a paste.

The MSDS for the 8341 flux paste only lists a couple of glycol ethers which are not very aggressive solvents. It's notable that they don't use any alcohol, but that may be part of the reason it's a paste and not a thin, runny liquid.

Hi group,

I didn't buy it today, but I got it last week. I obtained a Rode & Schwartz FSH3 Hand Held Spectrum Analyzer from eBay.

The datasheet can be found here:

https://cdn.rohde-schwarz.com/pws/dl_downloads/dl_common_library/dl_brochures_and_datasheets/pdf_1/FSH_dat_en.pdf (https://cdn.rohde-schwarz.com/pws/dl_downloads/dl_common_library/dl_brochures_and_datasheets/pdf_1/FSH_dat_en.pdf)

There are three models of the FSH3.

The .03 has the preamplifier
The .13 has the tracking generator
The .23 has both the generator and tracking generator.

There is a teardown and repair video (The Signal Path) of another unit here:

https://www.youtube.com/watch?v=qD05ZFVplE0 (https://www.youtube.com/watch?v=qD05ZFVplE0)

I had bought another FSH3.23 and attempted repair. The repair is documented here:

https://www.eevblog.com/forum/testgear/repair-rohde-shwarz-fsh3-portable-spectrum-analyzer/ (https://www.eevblog.com/forum/testgear/repair-rohde-shwarz-fsh3-portable-spectrum-analyzer/)

I had limited success with the repair.

1) fixed the 30V power supply, as documented in the thread.
2) I fixed the RF module, this is not documented. But it was a 3.3 Ohm resistor that was open circuit which prevent -5V from getting to the ADC driver.
3) The main board had an issue that the contrast adjustment was broken
4) The LCD module was damaged.
5) The LCD module is khs057qv1cr-g01. The one in the unit has 22 pin connector. I did find some displays with the same part number but they had a 16 pin connector.

I was trolling eBay for a couple of years before a suitable unit showed up.


Here is a picture from the eBay listing:

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=356673;image)

And some detailed pictures:

(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=356677;image)

One of the previous owners must have damaged the screen. They cut the center out of the screen and replaced just the center.  :D

I asked R&S for the prices on some parts. I got $360.00 USD for the plastic window and $1150.00 for the LCD module  :palm: These are approximate conversions from Canadian dollars.

I took the RF section and the case from the from the first unit that I bought and used the main board and display from the eBay unit.
I now have a very nice unit.

This morning I received my most expensive package, everything is custom except the solder paste.

The membrane keypad - did you get just one made? Was it expensive?

I've got another project that needs a membrane keypad here - but they are so expensive to get made in the UK.
I'm interested in some more information too.

I would be surprised if its 200RMB, thats about $40. Unless of course the factory already had that style and the only custom part was the screen printing.

I did some custom membranes from China, two buttons and two LEDs, most of the cost was NRE:
- Tooling $312 USD
- Membranes $207 for 300pc
- Shipping $80

Rated as waterproof and had adhesive backing + reinforced carbon connections. Without the LEDs, price could probably be halved.

no idea if it will work, no idea if it's even useful but there's  meter with a kilowatt range, theres a *huge* transformer (the whole weighs 66KG) and I figure there's a lot of fun in tearing it down which I may record and post on Youtube along with a teardown of the Bruker NMR amplifier I bought a while ago.

This piano looks painful to play. But at least it is a good idea that you can change the scale to major or minor, so that you don't accidentally touch the black keys, as with the chromatic scale setting. But I guess it is often used with scale off, like a theremin?

I'm very jealous!

I have bought items from this ebayer before, all good stuff but unfortunately they seem to have put a default postage of £40 on most of their items recently, even the small package items - otherwise I would have grabbed a few more items for stripping down.

It's fairly easy to use it in chromatic mode with reasonable accuracy, and I feel like I would be able to record most things in a couple of takes, especially if I practice a bit - today is the first day I'm playing with it and I'm already getting the hang of it.

It's also very fun to use it with the scale off, but not like a theremin - I feel like I can't really control that, - more like a piano, again with the thumbs, and then you can do vibrato like you would on a guitar or a violin, just by pressing your thumb.

But this thing is meant to be modded! First thing would be adding a CV input for the pitch. I have a 88key controller I will use instead of the actual keyboard.

Would be interesting to see a teardown of it. Maybe start another thread for it. I guess it uses capacitive sensing elements?

Recently I saw this instrument:

I think they are using resistive sensing elements. And the Korg is surprisingly cheap compared to this Kickstarter project. Usually anything that is called "analog" from Korg costs an arm and a leg :)

There isn't much to teardown. It's a single PCB with some pots, and there's even an official schematic for it: http://www.korg.com/download/global/monotron_duo_schematic/monotron_DUO_sch.pdf (http://www.korg.com/download/global/monotron_duo_schematic/monotron_DUO_sch.pdf)

https://www.youtube.com/watch?v=KX-IOYVBwUg (https://www.youtube.com/watch?v=KX-IOYVBwUg)

I'm not sure if I can take the ribbon keyboard apart, but maybe this can can shed some light on how it works... if I press on the lowest and highest point, it seems to kind of do an average pitch, but it's closer to the lowest note.
Title: Re: What did you buy today? Post your latest purchase!
Post by: FrankBuss on October 05, 2017, 05:59:51 pm
Interesting circuit, very simple and cheap with LM324 and 7414. And the keyboard is just one ribbon potentiometer according to the schematic diagram. Something like this:

https://www.sparkfun.com/products/8681 (https://www.sparkfun.com/products/8681)

Could be difficult to add a CV input for the frequency with exact 1 V per octave, if the MSP430 microcontroller does some correction to the control voltage. Or maybe they managed to build the analog part in a way that the microcontroller can just output a linear or exponential control voltage without feedback? Otherwise it would be difficult to correct for different master pitch settings, because this is not going into the MSP430. I wonder why they didn't do more in software, would be much simpler with less parts.

This is my first analog synth, so I'm also going to have to make my own midi to CV, probably with an arduino uno I have laying around from ages ago... if it still works. I can compensate for whatever (as soon as I actually can understand the circuit).
Title: Re: What did you buy today? Post your latest purchase!
Post by: FrankBuss on October 05, 2017, 06:14:11 pm
The most elegant modification would be to add MIDI input and implement your own firmware for the MSP430. My Beatstep Pro uses 3.5mm stereo jacks for MIDI, and then external cable adapters with the standard DIN connector, which can be bought for other gear as well, in case there is not much room for a normal DIN connector input.

I actually had a fun idea for a new project (and I can incorporate a couple of my projects, including one I already posted about here), and I think it will be helpful to have a working analog audio circuit around.

This time I'm going to post a project thread after I actually make something, though :P

Will give it a lick of black paint on the cover, will be almost as good as new then.  :-+

Yep.
I have "only" an analog scope without storage capabilities nor readout. Albeit a little old fashioned a 3437A would be a nice addon.  ;D
If I find a decent modern digital scope at an affordable price (has to be one with a "digital phosphor"-feature, I don't want to get behind the display capabilities of an analog scope) before bargaining a 3437A I will most likely not look for one any further.. -If TEA doesn't get me to get one anyway.  |O

It is only rated to 500 MHz but could be used well above that.

The last two swap meets I have gone to yielded this Atlas 350XL and yesterday the Atlas 350PS
The Atlas 350XL needs some work, low RX sens, and very little TX power out. This is good news because what is most likely wrong is common to both RX and TX, that means the 200W PA is good. The 350XL is clean inside but missing one shield. (I'll worry about that later).

The power supply was cheap enough, and was clean on the outside, the inside looks like it was store in a chicken coop...

This pair is a project for next year, there is already too many projects in the cue for this year... Another HP-8569, A Tek 2440, and my Motorola Micom 2ET HF radio.

Spotted an auction that had a "non-working" Tektronix 576 curve tracer as part of a lot of gear.  Threw in a bid of $125 thinking it couldn't be too hard to fix and won.  The curve tracer came with two adapters, the basic transistor and basic FET.  What was wrong?  Misadjustment of every knob on it, from focus and brightness on through positioning and a horrible combination of load resistor, step current and so on.  So after setting that right I have a nice curve tracer for way below market.

And then everything else, which included a repairable PCB router, 50A and 75A variable power supplies (both at 10 V), a Fluke 37 and 8840A multimeters, a Tektronix CDM250 multimeter, a slightly sick Tektronix 465B oscilloscope, several DAQs and several other odds and ends. 

Well worth the chance taken.

Rémi and URI, what are you using (or going to use) the 3437A for? A companion to an analog scope? I got some stuff a while ago that included that model, but I'm curious what some modern use cases would be for it.

No, the slots of the 34970 are empty. I'm not sure about the 3437A, I will read the manual and see how I can integrate it to my setup.

I thought of that too, but there is not enough space for a standard 7-segment display.
I also contacted Fluke to see it they may have left some of these displays and how much one would cost.

If I were doing it I would clone the entire PCB and just change the display area to accomodate the new components. Then I'd transfer the other existing components to the new PCB.

A three phase, 415V, 30kVA UPS, for $1.  Most of the batteries are removed, but it will be an interesting teardown when I get my hands on it.

This is a side effect of going down to Albury, for inspection of that huge machinery auction. Still not sure if I'll win a CNC lathe, but we'll see. I'm much less enthusiastic about that since discovering while talking with people there, that the machines on offer are less versatile than I'd thought. The factory bought machines only for specific manufacturing tasks, so they are very minimally optioned and tooled up. It was an interesting day though.

I took lots of photos, but not one of them comes anywhere near capturing the vastness of that place. I walked around in it all day, and still was alternately getting lost and finding things I'd not seen before.
The one inside view below is just a tiny corner, as marked on the building map.

Also, I think the past management were strange. There's a grid of isles throughout the factory, and on them the floor is painted with a glass-smooth paint. With oil everywhere, from the machines, and water (many roof leaks) it's literally the most slippery workspace walking surface I've ever encountered. Greased ball bearings on glass, in many places.

Also amazingly there is NO marking of any grid system. At first I thought I must be just not seeing it somehow, but no. Even the people that used to work there thought it was nuts. Not on the isle floor, or the columns, or the ceiling. Nothing.

During inspection the auction company handed out an A4-sized map of the building. Which made the details very tiny. They'd hand written their own grid refs along the diagram sides. But in several months of preparation for the auction and inspection, no one thought to write those numbers on the floor of the isles (near-white smooth paint) in felt pen or something. Result - the minute you walk a few modules away from an outer wall, then turn around a few times, you are lost again.

Which just made it more fun.

Turns out the place was shut down almost four years ago. All the machines have been sitting dead since then.

Just want to mention that the CNC lathes sale has 4 hours to go, and as soon as it ends all the online photos will vanish. If you haven't scrolled through the 4 pages of heavy machinery porn, I'd suggest doing so now. Have a box of tissues handy.

Also, some of the machines are still sitting at under $10, some even no bids. If you wanted a few tons of computerized behemoth, take a look. Be aware there's still the "removal fee" which is a few thousand dollars, plus freight costs. So don't bid casually. Oh, and registration to bid takes a while, verifications via SMS, etc.

URL: http://tigerassetgroup.com/sales/dsi1/ (http://tigerassetgroup.com/sales/dsi1/)
Scroll down to and click on "SALE 2. Closes 12pm (AEDT) 12th October. 85+ CNC Lathes"
Not saying which one I want, but it's well on it's way to a thousand dollars and will likely go over. (Plus $2200 removal fee.) Most of the appealing ones are already bid to several thousand, out of my range.

Not fussed, as I found out these don't actually have some of the machining capabilities I need. So now it's mostly just 'learning CNC', aka boy toy purchase, aka get this AND a big old manual lathe. Which I really shouldn't.

Edit: Btw to navigate that Pickles listing, choose sort by: lot number. And use "< Back to results" to return to where you were in the listing. Browser 'back' takes you back to page 1.

Edit 2. A few more traps for CNC nubies have come to light. Talking with an Okuma rep:
  Q: With a machine that has no tool position calibrator arm, can that arm be retrofitted?
  A: Basically no. The software in each machine is custom to that machine. So if there's no arm,
     the software won't have that facility. After adding the arm, would also have to ask Okuma for
     a new software build. Software comes on floppy disks, several disks per set. Very high cost.
     Code is not human-readable script, just binary blob.

  Q: So that applies to gantry loader integration too? You really can't just remove a gantry and tell
     the machine to ignore the absense?
  A: Correct. A customer recently had that situation. Bought a machine with a gantry loader, and
     wanted to run the machine without it. Cost of new software was $7.5K.

  Q: What is the code held in?
  A: Flash memory. There's also battery backed memory for machine state, etc.

Oh, and I'd previously been told that full schematics are available. But people at the factory (and from looking at actual manuals) say that is not correct. There are cabinet wiring diagrams, but no PCB schematics available. So a fault in something like a spindle variable frequency drive, costs several thousand for repair by manufacturer, or replacement.

Edit 3:
Final prices for the five Okuma Spaceturn LB250T CNC lathes.
All with additional $2200 removal fee, plus auctioneer's percentage, plus buyer's transport cost. That guy in WA...

149   E.H. Winthrop WA           $3,550
150   V.V. Matraville NSW        $5,050
151   E.H. Winthrop WA           $4,450
152   S.T. dandenong south VIC   $3,050  (I bid, my max $1350 for this machine with a major flaw.)
153   P.M. dandenong south VIC   $2,800  (Was going to bid on this. It looks bad, but only superficial. It went over my limit quickly.)

I think a lot of the larger machines didn't sell. According to people at the site on Monday, there will be a second auction of the dregs.

Since I have to go down there again to fetch the big UPS, I thought I'd buy something fun. Lot 605, a freestanding cubicle containing a small assembly line. Cubicle made of nice T-slot section, lots of pneumatics, controllers, two huge pneumatic actuator cylinders, etc. Would have been cool.
Unfortunately there's sometimes that one stubborn guy who won't accept being outbid. (Not me!) Combined with the Pickles deadline extension by 9 minutes every time someone bids, it makes for a frustrating waste of time.
After sitting there incremental bidding for about 20 minutes I quit when the value for money died.

Well, it's all good. Means I have more money free still to buy a big old lathe that can actually do what I want. And very amusingly... (story for later)

That auction cost me a grand total of $2.16. And I got a huge 3phase UPS, that I've been seeking for ages.

Now I need to shake this cold I have.


Edit #4. I'm informed by email from Pickles that both things I bid on but didn't win (Lot 152  the CNC LB250T lathe with no tool position calibration arm, and Lot 605 Assembly machine cubicle) were 'passed in' and "may be listed again in the near future."

Ha ha ha! So, they set themselves greedy, hidden price targets, and probably a lot of things failed to reach them. Presumably I only received notifications for lots I had bid on. I wonder what proportion of sales failed?
 >:D I hope most of them. Reality 2x4.

Figured it would be useful with my vacuum system with electrical feed-through to read the film resistance. Flashing a burst of a set metal could be useful. So I'll try to coat a slide and flash it with a pulsed laser.

Long term if I manage to follow though with a home made SEM it will be useful with a gold target. I only need a 2.25" diameter thin film of whatever metal to deposit to act as a target since this is is a DC type system, I think.

Go to post here, my vacuum system is in that thread page (start from top):

Some solar panels, 32x270W Trina Honey ( 8kW or so), and a three phase inverter Fronius Symo 7.0-3-M, getting 3.7kW at switch on at 430PM so reasonably happy so far.

An antique 22GHz analog spectrum analyser (Ailtech model 707, whatever that brand is) I would show pictures but she's not pretty, it's extrememly crusty, missing its bottom plate, and the knobs are well worn including a huge gauge around the main tuning knob from decades of careless fingers. It's supposed to be working and calibrated, but unfortunately its missing some weird old power connector so I can't power it up untill I find a way to connect mains. I did however get the manual, service info, and contact info of the original calibrator who was present at the sale. ;D

EDIT: did I mention it was only $50... ;D :P

BTW, screw Arrow. Octoparts reported it has the lowest price on the Winbond part, but its price and stock info are not stable, and over just a few days span, thousands of stock have vanished and now I'm looking at 4000 MOQ and 14 weeks lead time.
I thought SPI flash is common commodity and I can get them from anywhere, but I was wrong. SO8 package ones are everywhere, but UDFN8 2*3 chips are quite rare to find even from authorized distributors let along in the wild.
blueskull, really? Arrow is a large corporate distributor that deals with high volume customers all the time, stock is *extremely* volatile. Also, in my experience dealing with certain manufacturers' lack of planning or sometimes simply bad luck, stock is particularly unstable especially for high density packaging used in high volume designs, where tens of thousands of units can be swooped from the market in a mouse click in a time of desperation.

Some 500 pcs of 2Mbit dual read SPI flash chips from Freelancer Electronics (over stock, I'm a cheap person...). Was going to order some Winbond dual read SPI flash chips, but they ran out of stock and new back order MOQ is 4000 pcs...
I posted another thread in MCU subforum asking if I can replace them with Aldesto QSPI chips, but since I hard tied WP and HOLD to VCC, I decided not to take the risk of latching up the chip in case it accidentally goes into QSPI mode.

Also ordered is a batch of very special PCB from WellPCB, the special part it that it has copper pads on the very edge of the board, and hence the PCB manufacturer will have to prolong the pads, cut the PCB and shave excess copper and FR4 to make it the perfect size. It also features 0.1mm track/spacing and 0.2mm drill/0.1mm annular ring as well as panelization with a mix of routing and v scoring (and some other advanced features, such as high Tg, ENIG and 0.4mm thickness for 4 layers). Let's see how they handle this design.

I'm excited to see how it turns out if I pack 3 tiny BGAs, a UQFN, a UDFN, a crystal, 2 0.4mm pitch connectors and 39 passives on one side of a 12mm*12mm PCB.

What I didn't mention is that my apparent frugal approach is mostly dictated by the money I've been haemorrhaging the past two weeks on other purchases, with a few more on the horizon currently being negotiated ;D

I genuinely started looking into my moving plans more seriously again because of all the stuff I bought and the room that's inevitably going to need to set up. I don't think I can actually properly set it up until I've actually moved.

Because of other interest in CNC machines, a small update on my Deckel FP2-NC milling machine adventure. Some good and some ugly news.

Good: Machine arrived in good shape (big truck with little machine on it ;) ) and I got the electronics fixed, had to replace a blown transistor on the NPP90 board, initially suspected bad EPROMs, but was a visible blown transistor in the end.

Bad news: Some nasty galling/fretting/cold welding on the X-slide, wear/bad adjustment in the X-axis ballscrew trust bearings and a crapped out hydraulics pump. The galled X-ways are certainly the worst, not sure what to do about it, I'll probably ask the guys at practicalmachinist for advice (have a thread going there, too). Just in case anyone else buys such a machine, please inspect the X and Z ways before buying. Bellows on the X-axis are simply snapped on (same mechanism as in snap fasteners), so they are easy to pry off with a screwdriver for inspection.

I think the monkey operator splashed coolant behind the table, which flushed the lubrication and and started corrosion on the ways. Add some chips and the lack of lubrication and you get nasty galling like that.

Thrust bearings are easy to inspect by placing a dial indicator on the spindle face and moving the axis side to side. (you need an indicator with a long tip, couldn't fit my 1/1000mm indicator in the hole). X-thrust bearing has 4/100mm play/wear in my case.

Vertical spindle also suffered from monkey operator which made a million small dings while changing tools (and crashed it at least once, judging from the galling/cold welding ring at the edge). Found an hour counter in the top of the electrical cabinet a few days ago, 12000h only. So the monkey operators did quite some mayhem during that time, I've seen some machines with much more hours that were in better condition  :(.

yeah  - though if he's building them himself and prepared to spend the time, probably not a problem.. most of the vias in pads are for parts with accessible pins like the jellybean parts - so could be reworked... I'd be most worried about that xtal pad on this side. (assume other side doesn't have these on the QFN pads... that could get interesting)

To jump to a proper production run you could always cap the vias. it's not like the boards are made with cheap and simple process anyway. ;-)

Come one, don't be so picky!   ;)
I once bought a A3 capable film laminating device from a merchant based in germany that had a metal case without any transformer or galvanic isolation and without any PE-connection at all but had a fake CE-sign on it!  :palm:

I demanded the CE-declaration of conformity from the seller and cc'ed that to official control also.
Soon after that I noticed the seller took it out his range of products on offer. But he never informed me about the fact that he never should have sold this device to me neither did he offer me to return that death trap and to pay back my money.  :wtf:

So I kept it (and didn't dump it) because it's basically working really well but had to rework the design regarding electrical safety fundamentally to not getting struck with the first fault occuring.  8)

You have to be very careful with cheap devices from china with a AC power inlet on it. You get what you pay for. Mostly crap.  :scared:

Will it be worth the 211,- Euros? I hope so, it's in reasonable shape with feet on it.

After uncounted Kernel updates on my Linux desktop (which means I have to reinstall and reconfigure the GPIB driver subsystem each time) I wanted to have a separate, stable machine to connect my USB to GPIB adapters to and to run the scripts for steering and reading over GPIB.
Finally I gave a raspberry pi 3 a go and ordered one with the necessary accessories for starting with it.
As this path has already been walked down by many before I think I will succeed in one way or another.  :)

Some of the people selling on eBay are a bit nuts in their shipping (and regular prices).  Knowing what it costs me to ship heavy stuff cross country (and realizing that a box and packing materials aren't free), seeing a $50+ cost to ship something big and heavy is perfectly understandable.  When I see those crazy shipping charges for a tiny power supply or the like, my thought is 'good luck with that!'.

High shipping charges are effectively a visible reserve price for the item. Don't let it ruffle your feathers. The label "shipping" is a misnomer, especially since the seller has to pay fees on it as well as the closing price.

Yeah, it's pretty common to see shipping costs as part of the price. Some smart ass even offered a nice piece of equipment for 49 dollars, only to add another 150 in shipping. Some poor sod might just fall for it.

In this case, shipping was fairly reasonable, considering the distance and maybe some additional charges for packaging materials and time spent. It seems to be an actual shop, so they need to factor those costs in. However, all the prices were at least 150% of what they should be. As far as I could tell, it was just a regular chassis fan and a regular 3,5 mm jack cable. Sure, they were from recognized brands, but not rare or desirable in any way I could tell. All the other stuff was equally optimistically priced.

They weren't realistic when responding to offers either, so it was probably for the best to run into the three offer maximum. I never knew there was a thing, so I'm glad to find out now, rather than when I really do want the object.

Buyer beware, remember that if you want to return it for a refund, you will only get the actual price, postage is refundable so this could be a new scam, seller sells something that they know is likely to be returned because its not quite as described, you pay return postage and they refund the actual price (less postage) you loose out, then gain time and time again when other people also want to return it. They also get into Ebays good books because they seem to be ideal sellers because you pay, you return, they pay you the original selling price and so it goes on.

However, if you make a return under eBay Buyer Protection in the US (I don't know if it's different elsewhere), you get a full refund including shipping, and the seller has to pay the return shipping if they want the item back. I haven't purchased from anyone who has tried to get around these guarantees, but I wouldn't be surprised that some get away with shorting buyers.

Hard negotiating over ebay's make-an-offer function and per personal message led to an offer of 80,-€ being accepted.  :)

It will add good to my Chinese 30V/5A switching power supply (that has the same form factor) being versatile and quiet (no fans and low regulation noise).  :-+

In view of all this crappy and even dangerous mains powered equipment
around from dubious sources as well as a very serious incident involving a
construction light injuring a friend of mine, I have bought a Peaktech 2695
Insulation Tester also to ensure the safety of any mains powered items
I have repaired or built.

The 2695 comes in a nice carrying case and with a factory calibration certificate
with an attached Test Report. Calibrator is a Fluke 9100. Also included:
two probes, a brief manual, incidentally with no pic covering battery replacement,
a carrying strap and two large croc clips.

The Schuko adapter cord shown in the pic is not included.
Cobbled it together myself. Already did a lot of testing and found two
brand new CE marked mains cords (can’t remember the equipment
they came with) with an insulation resistance below 1 MegOhm.
The problem was found within the moulded IEC plug and not in the cable.
This alone has made this investment worthwhile.

OK, this time for sure...
An old lathe. Big enough to do some parts I need to make. No 'sale fell through' this time. It's at my place already, though the space for it isn't quite ready.

My 'buying a lathe' story is updated, here: http://everist.org/NobLog/20171004_buying_lathe.htm#macson (http://everist.org/NobLog/20171004_buying_lathe.htm#macson)

It's older than I am. Circa 1947 I think.

There's a single phase motor (roughly) fitted, but the original 3-phase motor, mounts and controls came with it. The big motor needs cleaning up, hopefully the windings are still OK. If it can be restored I'll use it, then add a variable frequency drive. The old controls are really only of historical interest. Cloth-insulated wiring...

Bought a couple of these cheap 8-digit frequency counters. They came without instructions (as usual) and strange things happen when you press the buttons :-) I'll figure it out eventually. Powered with 12v DC and fed with a 10MHz sine (1v p-p) from my Siglent SDG1025 (which I fitted with an upgraded TCXO) the output reads 10.000.000.51 on my Racal-Dana 1998 (fitted with an OCXO). On the first example I tried I got a readout of 10.000.015Hz, but the second was closer with 10.000.001Hz. There are no less than 4 trimmers on the tiny PCB so I assume it's possible to callibrate them somehow.

Edit: Left eveything to warm up for an hour and now example 2 is reading pretty much blob on @ 20MHz...

Yep, they never have any instructions, but they are pretty accurate , especially when you factor in the price, :popcorn:

I found a 'manual' online and it covers all the options. The trimpot closest to the xtal is used to adjust the readout (as expected) but it only managed to compensate for half the error at minimum (so the one that read 10.000.015 now reads 10.000.007 for a 10MHz input). So in terms of accuracy that's a fail compared to the other unit I bought with it. It draws ~100mA at mid-brightness setting and gets what I would call 'warm' - but I can keep my finger on it (the 7805) no problem. However, I'm machining a compact alloy case to hold these two and there's not going to be much free space inside, so I cemented heatsinks onto the 7805 regulators and now they run 'barely warm (technical description :-) ). I expect the alloy case itself will conduct any excess heat away that may build up inside. I think. Cost/Performance-wise these counters have to be a bargain though.

In great contrast to the frugal nature of the post above me i made a decision and purchased an oscillosope. There MIGHT be an argument it was a unilateral decision and unwise but any such argument can be wholly dismissed as blasphemy.
http://preview.tinyurl.com/tektronix7704A (http://preview.tinyurl.com/tektronix7704A)

Fully loaded Tektronix 7704A with 7B53A, 7A18, 7A26 & 7BA85 and a video showing traces on the screen.
Shipping was bloody murder but it is in proper contrast to the price it went for, i won uncontested.

Following up my last impulsive decision i made another, a lot of 4 Tektronix probes. 2 with read out; 1 with hook, readout,  ground clip and 1x/10x option.
So really at used Tektronix probe prices, just one nice probe with 3 free ones.  :-DD

and finally the one great one...

Nearly completed the enclosure, rather tricky to get the hole spacings correct - electronic PCBs are not an exact science it seems and unlike engineered bits dimensions can vary :-)  So it was tricky transferring relative positions to a chunk of metal. Anyway, the basic thing is done - I'll make some nice captive button caps and when the BNC panel plugs eventually turn up they will go on the LH side. I'll install a power switch on the front and a 2.5mm DC input jack on the back. In one of the pics you can just see the heatsinks I installed.

These arrived from Elecrow last night.  They are my first design (reverse engineer) using KiCad.  I'm generally pleased with how they turned out, for a "first cut".  I'll let people guess what they are for a day and then put up a picture of the other sides which will give it away.  A couple of hints: they are designed to "live" in a Pomona 3301 enclosure, the originals were marketed in 1975.

They all sit in the one enclosure? Was wondering if that was a DB9 to the outside world or a board to board connection.. hm

Also delivered today, some nice BNC plugs and a cheap Chinese Pickit clone. Be interesting to see if it works...

It works, and its better than the official version as they are thoughtful enough to include a programming cable.
Mike did a review of the ~$200 ICD4, and it doesn't have a 5 pin header cable either :palm: .




I can't communicate with this one :(   DeviceManager (Win7-64) sees the device and lists it as a Pickit3 but there is no driver. The genuine Pickit 3 lists as an HID device (from what I;ve read) so Windows provides its in-built driver. MPLab doesn't see it, neither does mikroC Pro, so it's pretty useless at the moment. Did a web search but found nothing..

The 9-pin connection on the rightmost board is a DB-9 to an S-100 interface card (the outside world).  The 9-pin pads on the other boards are board to board.  All three boards act as a single unit.  I'll give you another hint.  There is a threaded hole in the enclosure as well, .625 inch, 32TPI.

Check this site under "Using The PICkit 3 Clone With The MPLAB X IDE": http://www.sinistercircuits.com/pickit3_clone01.php (http://www.sinistercircuits.com/pickit3_clone01.php)
Or maybe some hints here, about holding the button before plugging it in: https://forum.allaboutcircuits.com/threads/pickit-3-issue.120312/ (https://forum.allaboutcircuits.com/threads/pickit-3-issue.120312/)

It could have an older FW on it.

Also try another USB cable just to rule that out, although it shouldn't be the problem as it is showing up in device manager.

Thanks for the links, but nothing described quite fits the issue I have here. Any device like this requires a driver through which a program will communicate with it and this Pickit3 doesn't have one installed, so as far as any running program is concerned my Pickit3 simply doesn't exist. Yes, it's listed in DeviceManager but that's all I'll get without a driver. Maybe I can force load a driver of some sort...

This is interesting for me because I recently ordered the same module, except in green.

You look like you machined that case out of solid metal!?

 Anyway, i am sure your device is going to look just great. Nice!

Nearly completed the enclosure, rather tricky to get the hole spacings correct - electronic PCBs are not an exact science it seems and unlike engineered bits dimensions can vary :-)  So it was tricky transferring relative positions to a chunk of metal. Anyway, the basic thing is done - I'll make some nice captive button caps and when the BNC panel plugs eventually turn up they will go on the LH side. I'll install a power switch on the front and a 2.5mm DC input jack on the back. In one of the pics you can just see the heatsinks I installed.

Yes mine are also green :)  They offer an excessively bright display though and only need to be set to brightness level '3' (out of 8 ), but I've also ordered some dark green acetate (L124 "Dark Green") to go over the front to improve readability and that only has 30% transmission so I may need to increase brightness a little.

It's not solid metal but alloy box-section, which I have a lot of :) . It's a lot cheaper than buying discrete project boxes and you can make a lot of small boxes from one 3M length! However I should have machined off the front face _first_ then cut out the holes but like an idiot I did it the other way around and the narrow strip between the two displays really didn't like being fly-cut because there was little support remaining and it chattered. Oh well.

An Agilent 34401a, to go with the voltage reference and lead set I got earlier :-)

In pristine condition, supposedly coming from a cleanroom. The only drawback is the display; by the looks of it it spent its days in 5 digit mode, as the 6th digit is the most clear (and the least worn). Well, a new display is always a possibility; for now I am quite happy with this meter.

For anyone who was curious, here's the other side of those boards.  I never realized how hard it is to take a clear picture of a circuit board.  (If you can't make it out, the text at the top of the three boards reads "CROMEMCO ACC-1", "CROMEMCO ACC-2" and "CROMEMCO ACC-3")

I finished the job on the frequency counter enclosure, and in the end I installed a couple of Nemo sockets because I have quite a few lying around (and patch cables + Nemo>BNC adapters). Out of curiosity I trawled ebay for the cost of these connectors and nearly fell out my chair!

I turned up some captive button caps from stainless rod, whilest on the back is the 2.5mm DC jack socket, a toggle switch, and two holes which line up with the trim pots for callibration. Four 3M sticky feet and the job's done :-)

Very nice and neat job, when I did mine I used a piece of coloured acetate in front of the display to hid the unused digits. Why two counters in the same case, plus the other frequency counter?

Not that your boxes look bad or anything, they actually are quite well done, but just for future reference it's sometimes possible to mount boards from the back side of the box, resulting in a little bit cleaner look. It is a little more trouble getting it all to align correctly though.

I guess if the display were not flush with the face it would then be possible, but not with the LED displays the way they are (the PCB assembly with stand-offs would be deeper than the inside dimension allows). I had intended to use c'sunk screws but the LH stand-offs are so close to the display there isn't really enough room to have a countersunk hole deep enough to sink the head flush. Hence the use of button-head screws. All sorts of ways to do this job though :)

If screws need to be at the front of the panel, there are many ways to make it a design feature. The screws in this case look pretty good. I would even go further and make a "safety bar" type design from threaded u-shaped rods, like the handles used on 19in Audio gear.

Somehow lost the picture in my previous post.

This is sort of what I was suggesting. I used regular 4-40 standoffs, just went in from the back.  There was enough clearance on top of the board for the display to still mount flush with the inside of the lid. There wasn't much I could do about the screws holding the lid on though.

Oh nice job, and quite do-able if you have a lid, my box is just solid rectangular alloy section though - no lid - and the PCB assembly(s) need to be slid into position from the end.

In fact, by the time I have made a cover to hold the dark-green gel contrast enhancer (using something akin to a picture frame to hold it in place) you probably won't see the screws anyway. I haven't planned this out exactly (like I should).

It was a couple of bucks and a drive through Los Angeles. It fails at the ROM check so far which prevents any further testing. Cosmetically it looks great, the power supplies are all working well. There is no evidence of bodged repair attempts. I have some new EEPROMs on the way and another forum member pointed out a site where someone is hosting images of the ROM. Pretty cool.

Started a thread for this repair.

Rob - are you sure that fits the 5245L?  That's the plug in that came in the 5360A computing counter I got a few years back (the source of the wire-wrapped backplane photo), and I could have sworn that one of the options for the 5360A was an adapter frame to let it utilize the slightly smaller 5245 series of plug ins...

I fear you might need to buy another counter to use that!   ;)  (It's all good, though - the 5360A sports nixies.)

Yeah, that was definitely worth a roll of the dice.  I just looked at your other thread, great news that the necessary images are out there.  I've never used a burner; should really get one and learn, and also get some of the needed chips to have on hand before they become unobtanium.

Mine came with 'free' shipping from the 'bay, and was packed relative to the shipping cost so the chassis got a bit buggered up in transit.  Built like a tank, though - it still works.  The only other real bother is that it was missing the knob, which seems to be a somewhat odd size.  It currently has an ugly generic black knob.

Good luck with the repair and I'll be watching the other thread with my fingers crossed looking for updates.

That depends. There are units (CIS) that have a very narrow focus, others can do 2...3 cm focus range, they make good scans of populated PCBs.

No, it doesn't seem to need a continuous internet connection luckily. As far as tracking is concerned, it's not gathering any more than the web interface does.

These are unpopulated boards, they'll scan cleanly on any flatbed scanner.

And as capt bullshot said, CCD flatbed scanners have significant depth of field. (That's what I've got.) CIS scanners do not, and sadly they're the most common in all-in-ones. Still work for unpopulated PCBs.

Wow. For PCB shots, I usually use an 800lm flashlight, F8.0 and short shutter (1/500~1/160) with ISO100.
Well, I only shoot small PCBs, never bigger than 10cm*10cm, so 800lm serves me very well.
I almost never use a ring light, they never play well with reflective solder resist.

I don't use PCBs much, i do if i am going for more than a one off but every prototype or one off is perfboard with 38 AWG wire.

I often mistake my hair for it  :-DD

Where do you get these 10,000 lumen bulbs?
I have a Cree 100 watt equivalent bulb that's rated 1100 lumens. Are you sure you haven't misplaced a decimal point?

My LED shoplights from Home Depot are only 3400 lumens which is pretty bright considering they're only 3 ft. long.

Okay, that explains it. For some reason I though you were talking about standard Edison base LED bulbs. I guess there must be some reason you need that much light in that small size, otherwise LED makes more sense.

It is not size that matters, it is the cost. LEDs are cheaper to run but at my desired brightness their not only highway robbery their murder.
I like such a high brightness for a number of reasons, the size of the wires i work with being the largest motivation.

After the fiasco with the cheap Chinese case marking my 87V, I've bought a Fluke C100 case. Supposedly it's compatible with the 87V, but it's sloshing around there in a way I'm not comfortable with. Images on the internet show it fitting more snugly in the smaller pocket when you remove the boot, but I don't want to take the boot off all the time. Leaving it off isn't an option due to the stand being integrated.

Good thing I got the case fairly cheaply. Guess I'm looking for case #3 now  ::)

Is that actually Xiaomi or Wiha? It sounds like slapping a few brands with a good reputation on a box, especially considering the provenance. I could very well be wrong, though.

Regardless, it's a good looking set.

I ordered two 20mm plates of acrylic glass today to be used as the support for the console above my bench where all my boatanchors reside on.

Something has to be done:  :o
(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=365540;image)

Don't worry, it's still safe because it still deformes/swings elastically, so it won't break all at once.  8)

It's so much out of the horizontal position because the support (the near triangular plate underneath the console) has rotated around the middle of its three mounting screws. And that was possible because the drilling holes are a bit larger than the screws diameter.
I plan to use the plates as a support that sits on the bench surface so that the 40mmx40mm Aluminium posts don't have to bear all the weight alone. I'll substitute the 40mmx40mm (2mm thickness) Aluminium posts with steel ones of the same size but 3mm thickness also.

If I take into consideration that nearly my whole test equipment is sitting up there it's no wonder it turned that way:
Three HP linear system power supplies (2x6643A,1x6632B), two HP 3488A, two HP 3456A voltmeters, one HP 3457A Multimeter, one Knick Calibrator (full width), one HP LCR Meter, three Fluke counters, two Philips Multimeters (PM2534/2535), one classic Tube Oscilloscope and a HP3437 System Voltmeter, my GPIB Cable stock plus the unavoidable junk everyone collects at his lab bench..   ;D

I just picked up from my local surplus store an HP 3466A bench DMM for the princely sum of $30 USD.  It had been sitting for a couple of weeks and I found out why.  The test leads I brought and the test leads they had there were loose in the jacks.  I was able to test the meter by squeezing the leads in the jacks together a little.  I also replaced the plugs on the set of leads I am going to use with a set of plugs from Frankie's eBay store.  You can see how clean the meter is, I just touched the bezel with IPA where the price tag was.  The  meter works fine on \$\Omega\$ and DCV but there is odd behavior on ACV.  When I press the button for ACV the indicator goes to \$\Omega\$ instead of V, which it does when I press DCV.  I am very leery of trying to measure ACV  There is nothing in the manual that I could find indicating whether or not this happens.  If anyone has this meter, does your meter do the same?  It isn't a big deal.  It will be used for working on company equipment where I will use DCV and \$\Omega\$ settings, no ACV.

I have this same model of meter in my collection and the answer is no, it does not do this and neither should it. Does the correct LED light up on DCV, it should be either mV or V depending on if the meter is in auto or a manual range has been selected.

However I think that this more likely down to dirty switch contacts or a bad connection inside somewhere.

Yes, it does and works fine on DCV.  I had it open but I am not sure where to spray with contact cleaner to actually get into the switch.  I will have to have another look at some point.  As I said, it won't ever see ACV so not a big deal if it doesn't get sorted.  I will also try working the switches to see if that helps.  I also didn't take it completely apart to look for bad solder joints.  That might also be on tap, then I can check the switch with a meter.  That is a project for another day.

Do you like the meter?  Regardless, I think I got an good price on it and it will serve my purposes for sure.

Yes I do like the meter a lot, its not my goto meter for everyday use however that duty tends to fall to my Iso-Tech IDM-203. Has yours got the battery option or is it just a plain 3466?
The meter itself is very easy to strip down and gives you complete access to the switches. There is a service manual on line that you can download for free, just google it.

I use it really when I need some extra accuracy or when I'm doing a worth while project that will take a bit of time to do, I also have a Fluke 8505A that gives me 6.5 digit accuracy but that is a beast of meter that takes up about 5 times the space on the bench that the 3466A does so it does not get used that often. :popcorn:

Yes, it's rather expensive compared to something made of wood. I chose it anyway because I wanted my bench to be lighted from the light coming in through the window. Imagine the supports (50cm wide and 63cm high) would be made of wood (something not transparent) my bench would always have to be lightened artificially -even with full daylight outside.

I hope 20mm acrylic glass is stable and capable of bearing the load, otherwise it would be an expensive failure.  :palm:
But since whole cabins of elevators are made of acrylic glass I'm confident it'll cope..   :)
The acrylic glass will be attached to and held by a 40mmx40mm (3mm thick wall) steel post. So it won't be bearing the whole weight on its own.

I did download the owner/service manual.  It does have the battery option.  There is no battery in it and it wasn't connected when I peeked inside.  I plan on getting back into it and try to clean the switches but, unfortunately, other things come first, like finding time to change the brakes on my van.  Work got in the way last week as I worked 60 hours including a chunk of the weekend.

I think it will do just fine but it might be an idea to try and brace the edges of the top shelf with some steel strips or angle iron back to the main vertical support because you say that you're going to be reusing the triangular plates that are there now, on the bottom? If you could get some steel strips to make a sort of triangular frame, it would benefit and help prevent your kit crashing to the bench or the floor if the glass should fail. The strips would not block any light in real terms either.

I think it will do just fine but it might be an idea to try and brace the edges of the top shelf with some steel strips or angle iron back to the main vertical support because you say that you're going to be reusing the triangular plates that are there now, on the bottom? If you could get some steel strips to make a sort of triangular frame, it would benefit and help prevent your kit crashing to the bench or the floor if the glass should fail. The strips would not block any light in real terms either.

No, I won't be reusing the triangular plates. I will exchange the triangular plates with rectangular plates of 20mm acrylic glass that will rest upon the surface of the bench table and will go up to where the console sits now in one piece. So the upper horizontal edge of the acrylic glass plates will be in the identical position as the one of the triangular plates. By the way these are made only of 19mm MDF.

Oh well if their only MDF, I think the acrylic glass will just fine as they will be sitting on the bench top and attached to the top shelf at the edges and hopefully also at the centre support.

One problem of acrylic is that it tends to shatter, rather than gradually yield. Though thicker sheets may me better behaved.

Yep. I have already taken into account that acrylic glass tends to be easily damageable by notching effects.
In consequence I will use the whole cross section area of the plate and will also put a flat aluminium profile on top to even possible stress points.
For the screws that hold the plate to the post I'll use washers to minimize stress concentration.

I'm near the end of my night shift and went on Ebay.  That's a dangerous combination.

Just bought a 3kva variac.  Total impulse purchase.

https://www.ebay.ca/itm/3-KVA-Variac-variable-autotransformer-120-volts-input-0-140-volts-output/311990280782?hash=item48a411e24e:g:HjUAAOSwyjBW7f-e (https://www.ebay.ca/itm/3-KVA-Variac-variable-autotransformer-120-volts-input-0-140-volts-output/311990280782?hash=item48a411e24e:g:HjUAAOSwyjBW7f-e)

It will come in handy though as I've been meaning to mess with SMPS builds, so at least I can dial the voltage up a bit at a time instead of applying full 120 to my contraptions. :P

Finally got these boatanchors home! Purchased a year ago for the whopping sum of £10 - wait technically I bought it year ago, but I only got them today - that still counts right ;)?

Racal Dana 5002 w/manual -- Free
Fluke 6160A - blown power supply -- Free with 1 Hernia
Wavetech 178 w/manual -- £10

Not a bad haul as long as you can get people to carry them for you!

Anybody know where I can get a copy of the service manual for the Fluke? Google isn't yielding to my powers today for some reason ;)

The peak temperature isn't the problem with tempered glass, how fast the temperature changes is what can make it fail. If the glass is pre-warmed it wouldn't be a problem, but if the glass is cold and gets a sudden blast of a few hundred degrees, it will probably rain glass in your lab. Is the glass laminated?

I received a bag of wirewound ceramic resistors today, so I can do some more high powered tinkering and maybe use them as quick and dirty load stand-ins. I did a few spot checks and most are close enough for comfort. These aren't meant to be precision resistors anyway. There are one or two outliers that don't correspond with their supposed value at all, so I guess those got mislabelled.

Glass can also be unpredictable. Just a minor surface scratch can significantly weaken the sheet as a whole.

Today is a public holiday here in Germany to commemorate protestant reformation initiated by Martin Luther 500 years ago.

Also a good opportunity to pimp my lab bench with a new antistatic mat:

(http://www.elme.it/images/foto/157KITnuovo_g.jpg)

It's a complete set. The mat is made of silicone that hopefully will lie totally flat on my bench.
That's something my current mat never did neither is it heat proof.  :--
It shows that with many solder marks burned deeply in its surface. 

Time to say goodbye!

Also ordered a relay to improve my cheap desoldering station (get the trigger switch out of the way of the vac pumps current) and several fans for pimping some old test gear to make lab life less noisy and so a little more acoustically convenient.  :)

Ah, not a buy but in preparation to fit the relay into the desoldering station. I opened it up and took the chance to also change the mains power switching from one pole to two pole. I feel better with that.
No prob since it is built with only one pole of the power switch used..  :palm:

Haha that I think was a step to far seeing as the bit you hold in your hand is 24V and now all that you seem to have done is introduce another point of failure. It just now takes any pole of the switch to fail and you're stuffed, whereas before if the pole went O/C, you could simply swap the connections over to the unused pole and bingo, back in business again :-//.

Ah, built in spare parts?  :-DD
I've never seen such a switch failing electrically but mechanically (lost latching function). I've got enough spare parts in stock to replace that switch. But I think I will never have to touch them considering the only 80W of the unit..   :popcorn:

But seriously this SP or DP switch debate has been going on for years and the only real advantage of a DP system is as protection against wrongly wired mains distribution systems which should not happen if the person doing the installation is a fully qualified person. This came about because switched socket outlets, if wired incorrectly would still be leaving the live or the hot wire wire directly connected to the plugged in equipment when the socket switch was switched off. Certain manufacturers used this "scare" technique to scare people who could write specifications that dictate new installations must incorporate these devices in order to win business away from more established market leaders who did not have such sockets within their product portfolios.

There is no real benefit in a properly installed system, equipment plugged in, if it is made of metal, the metal casing must be earthed and back at the source the neutral and earth are bonded together so even with the neutral switched off via the DP switch, your still leaving the earth connected which in a wrongly wired system is still connected to a potentially dangerous supply?

But in the case of the desoldering station, the heating element in the handgun is running at 24v, a safe voltage so why bother with DP on the unit itself?

Note that a lot of German wall sockets are reversible. There is no "wired incorrectly", either way is correct, though many will be wired a certain way regardless.

Yes I know, but I think the same is also true of the USA, but in the case of 3 pin plugs which have to be used in order to connect the earth cable, then these plugs are not reversible so surely 2 pin plugs are only to be fitted to double insulated loads, such as electric razors and hair dryers etc??

There's an earth pin on both sides, on both the plug and the socket end. This ensures an Earth connection is always made. This socket is also compatible with double insulated two pin devices, which utilize none of the earth plugs.

Argh, now I see why some people see the need for DP switches, that just cannot happen with the UK style of socket as the pins are arranged in a triangular shape that prevents the live pin being connected to the neutral on the socket so only a SP switch is really required on UK products, seems to me be the safest system around, especially when the first connection and the last connection to be made and broken is the earth.

The latter isn't precluded by this plug style. The earth being broken the last works exactly the same. It's also somewhat redundant, as you have two contacts.

Again, there isn't really a live pin as such with a schuko socket. You could argue that a system with always the same live pin is more predictable, but the problem is that not all sockets are wired correctly, causing potentially dangerous situation because fuses or switches will not be behaving as expected. The Schuko plug eliminates any uncertainty by declaring both pins potentially live, thus also eliminating the risks associated with erroneously wired sockets.

One advantage of the UK plug seems to be the built in fuse, though that does of course require knowledge of what actually is the live side. The safety shutters are also a distinct benefit, although it should be noted some variants of the Schuko also have these. Of course, both designs seem to do their job fairly well, with mishaps being rare and typically caused by other issues.

While I agree the UK plug seems to be the safest around - I think it is because of the bulk of the contact pins.  Our AU plug is angled to prevent Phase and Neutral being interchanged, even if the plug has no earth.  We still treat all P-N wiring as potentially at medium voltage regardless.  :-)

The Schuko plug eliminates any uncertainty by declaring both pins potentially live, thus also eliminating the risks associated with erroneously wired sockets.

That's it. And that can lead to unwanted/dangerous situations using equipment one being unaware of it missing basic safety  requirements.
About two years ago I had fun with a switchable multiple socket outlet for connecting my test equipment to the mains.
I used its switch for cutting off mains due to energy costs: A counter and a function generator had OCXOs and drew current all the time even switched off with their on/off switch.
One day (I was in another room) all of a sudden mains power was cut off due to fuse tripping. A 16A automatic fuse had tripped.  ???
When I went to the fuse box I came along the door of the room with my bench in it and I noticed a very strange, burnt smell. I opened the door and the whole room was filled with white smoke that burnt my eyes!  :o

What had happened? The switch of the switchable multiple socket outlet was only SP. (And I hadn't thought of and therefore hadn't checked it  :palm:)
The function generator had a 'famous for inevitably failing' Schaeffer EMI mains filter socket built in.
In the way the Schuko plug of that the switchable multiple socket outlet was plugged its SP switch had opened neutral leaving the phase and protective earth connected.

That very day the EMI filters time had come. So it decided to fail between mains and protective earth blowing out as much magic smoke as it could. As this started slowly with increasing current it must have taken several minutes before the 16A automatic fuse tripped.
I was lucky it didn't start to burn seriously!  :phew:
The cleaning of that mess (I still use my HP 3325B, btw  :)) took me uncounted hours of literally stripping it down to the last screw.

That switchable multiple socket outlet went to the garbage and was replaced with one of good quality that I checked positively to have a DP switch in it.
That incident brought me to check for DP mains switches in equipment connected to mains in my household regularly.

Back to the desoldering station: It contains a switching power supply that has semiconductors and capacitors on the hot side in a metal housing connected to protective earth. Using DP switching is simply safe(r) using the Schuko mains plug system. But I'm  :horse:  :popcorn:

Safety shutters are built in every Schuko outlet sold in germany for years now. Older Schuko outlets came without safety shutters and there are still many around. That's the reason why safety shutters for retrofitting Schuko outlets are still being sold in numbers: Everytime a child is born the parents become aware of the possible dangers of playing around at mains outlets without safety shutters.   ;)

I agree in that instance, but if the wiring standards / regulations were improved to prevent plugs being inserted incorrectly such as the UK system, then a SP switch in the live side is all that is required. Had that been the case then your HP 3325B would not have blown its filter caps either because switching the switch off on the multiple socket outlet. :popcorn:

Same in Australia, although we go two steps further:

1/ It's physically impossible to insert a non-earthed Plug in "the wrong way" as the active and neutral pins are angled
2/ We have Power switches on all power points - it's been mandatory since forever

16A across mains and ground? There the hell is the GFCI?
You must be lucky since without a GFCI, a leakage path to ground plus a faulty ground connection means instant death when you touch anything grounded on that table.

Ground connections at my bench had been checked manually.  :)
Only the mains circuit of the bathroom is RCD protected in the fuse box of my flat.
Meanwhile my bench has a local RCD protecting 8 mains outlets there I'm using for powering my test gear.  And each pair of those eight mains outlets is protected by an 10A automatic fuse. :)

It's said to make sure if a plug was accidentally pulled out by kicking, there's a (marginally) higher chance for the Australian plug to have ground pin break last, after L and N pins.
If a Chinese plug was yanked out by a kick, due to the downward angle, ground will break first, then followed by power pins.
If the plug was partially yanked out, there's a chance that the appliance will still work, but without ground pin, which is a safety risk.
Finally, Australia is on the south hemisphere, where things are inverted than us living in the north.

All pretty slim rationales really.

They seem to do the job fairly well. Don't forget that a mind blowing number of people is working with 230V on a daily basis with no or minimal training and that people getting hurt is incredibly rare. That's a testament to the effectiveness of either.

All of this reinventing the power plug seems to me to be, both overkill and all to do about next to nothing. Granted it does keep engineers and designers employed, but in the end does it really serve a tangible purpose??

The US un-grounded plug has been with us (here in the states) since the beginning of electrification of homes and businesses. The polarized plug was an improvement, after that the three wire plug was the logical end of that evolution.

Limiting the exposed contact aria, could be an improvement except for the design of the socket contacts which wipe the sides of the plug prongs providing a self cleaning action.

There comes a point when reinventing the plug just drives up the cost of an appliance.

One plus with the Chinese plug with ground on top, that prevents any thin conductive object or wire falling from above from potentially bridging the two conductors and starting a fire.

As its likely to make contact with the ground first.

So it was you who outbid me on this before I could make another bid, the auction finished  :palm:
I did wonder if the winner was a member or not, now I know  :-+


Oops - Sorry  ;)   I didn't own a bench DMM and was in the market for something to tide me over. I lost out on the last 3 or 4 I bid on recently so was pleased to get this one. I doubt it will be the last one I buy though and will upgrade when I find something better (at reasonable cost).

Caused me to re-organise my tiny bench area yet again to to make room for it. I don't like stacking stuff so high but I have no option.

Haha, you'll be buying a few more then to catch me up, currently I have 6 bench meters.  :-DD TBH I never expected to win that one seeing as I put a maximum cheeky bid of £60 on because it is still currently being sold new for £261 from CPC and I was somewhat surprised to see that it went for so little. I expect that you had bid far higher for it than what you won it for, so fair play to you, you really grabbed a bargain there. :clap:

Looking at your stack there, you have some lovely kit already, I'm envious of that stack  :popcorn:

I was really looking for a 34401A and missed out by £10 last week :(  I only need 1 accurate bench DMM for times when I need a reference and apart from that I make do with the hand-helds for most other work. There are some stupid asking prices around, look at the stuff from top_quality_tools on ebay (they want something like £350 for that TTi DMM IIRC...!) So working out what is actually good buying price is tricky. I bid £70 for that one.

I would like an analog 'scope to replace the 465B I had that exploded a few years ago, and keep looking at the HP54520A. Not sure how good they are.
Title: Re: What did you buy today? Post your latest purchase!
Post by: Specmaster on November 01, 2017, 08:52:51 pm
Yes I agree, must be nuts to £350 for something that normally sells £261 or less from RS when they have in stock. I don't think that will be available much longer now, they have newer models with LCD screens now.

Wow that's a big jump up you're looking at in scopes from 100Mhz to 500Mhz, do you really need that speed?

I've just restored a lovely HP 1740A and now working on another 100Mhz scope that looks like it just came from the factory almost, a Goldstar OS - 9100D.

Not “a lot”. All. Germany’s Schuko outlet is always reversible.

Yes I know, but I think the same is also true of the USA, but in the case of 3 pin plugs which have to be used in order to connect the earth cable, then these plugs are not reversible so surely 2 pin plugs are only to be fitted to double insulated loads, such as electric razors and hair dryers etc??
Definitely not true of the USA. USA has strict requirements for wiring, because it’s normal for ground and neutral to be bonded. USA also commonly uses polarized ungrounded plugs.

Note that the NEMA standards in North America also specify that ground should be on top (or if the outlet is mounted sideways, with neutral up) for precisely this reason. Seems to be often ignored, though, since people are kind of accustomed to the surprised smiley face orientation.

Of course, if NEMA would just finally require sleeved pins, like UK, Europlug, AUS, etc already do, that particular risk would be substantially mitigated, as well as reducing the risk of accidental contact when unplugging a plug.

The ground pin is up for commercial installations, while it's on the bottom for residential installations (surprised smiley as you call it).

I've actually had that happen to me.
To do some job ( I forget what it was now), we used lengths of piano wire.
As they were hard to store, they ended up on the shelf at the rear of the workbench.
One day, one fell down, just as suggested, except that it only landed on the Active pin, so there was no fire,but the end of the piano wire touched my arm.

My reaction was to jerk my arm away, which, as the wire was so light & springy, broke the connection.

This can't happen with more modern versions of these plugs, as they are insulated for the first cm or so.

Source?

We are talking about ordinary household/office sockets here, not industrial outlets. There might be some ancient obsolete sockets in some really old installations, but even upon searching, I haven't been able to find any kind of regular outlet available in Germany now that isn't a Schuko. (For high-power applications, the industrial CEE outlets seem to be used.)

This page seems to agree with me: it says "We went to the effort to depict all the plugs and matching sockets that are common in Germany".

For that price they can't be Cree ir it is a bad batch or surplus. Look at feet of the led there should be a marking. Anyway if they work and keep on working you can make some nice streetlantern with them  :)

It's a mat of an Italian company, ELME (http://www.elme.it).
You can find it on their web page presented in different languages, e.g. auf deutsch (http://www.elme.it/tab_articoli_de.asp?tip=375) or in english (http://www.elme.it/tab_articoli.asp?tip=375).

I ordered mine from TME Electronic Components (https://www.tme.eu/de/).
They also provide a swiss version of their web site (https://www.tme.eu/ch/).  :)
Search for "157kit" on their web site and as the result you'll get the different ELME ESD mats they offer.

The cable is for my Hameg CRO to replace some of the cables that have over the time broken terminations enough times to make the cables too short to reach. I was assured that the new cable was the the correct one and the same as the old one (the short piece) but its slightly narrower and also nowhere near as stiff so the conductor core is smaller and may not be gripped in the push fit sockets  :scared:

Vielen Dank, URI! I’ll take a look. The website just says they’re “rubber” without saying “silicone”, but I need another ESD mat anyway. (I have one now covering 1/3 of my desk/bench, but I’d like to expand the ESD-safe area.)

I’m also really interested in a cushioned ESD floor mat like their RLX-AST, but tme.eu doesn’t carry it. (The modern laminate floor in my apartment is taking damage from falling tools, parts, etc. so I really need floor protection, but I also want it cushioned, for foot comfort. It’s an adjustable desk, used standing more often than not.) I’ve asked the manufacturer if they can guide me to a distributor for it.

Silicone antistatic mat? Where’d you find that? Can you share a link?

Sure:  ;)
It's a mat of an Italian company, ELME (http://www.elme.it).

The German description says "Synthesekautschuk", english: "Synthetic rubber". That's a term for a material class with many members including "Silikonkautschuk" (silicone rubber). Since ELME ESD mats are specified to withstand temperatures up to 440°C I don't think it's a synthetic rubber with characteristics like natural rubber but indeed something like silicone rubber.

Thanks for the clarification. I’m curious as to what it is when you get yours. I’m reasonably sure that synthetic rubbers exist that handle high temperatures (they’re regularly used in automobile engines, for example), so since they don’t expressly say “silicone”, I’d be very surprised if that’s what it is. That said, regardless of material, 440C is better than my current mat, which goes to something under 300 I think.

FWIW, rubber ESD mats are made of nitrile rubber rather than silicone rubber *.

* Both nitrile and silicone can be made conductive by filling it with carbon, but you don't want a conductive surface for testing powered devices. And silicone on it's own isn't dissipative.

Hmmm. I'm not a chemist and I see your point, but as far as I wiki'ed that, nitrile rubber isn't 440°C heat proof. So it must be something else. I'm almost sure that it's PVC-free and that's what counts most for me because I suspect my old mat to be made of PVC or something related. In fact it isn't solder-proof and it stinks awfully chemically (nut burnt like rubber) when it gets hot (..solder iron..).

Same here. For some reason the 'HI' terminals went OK, while the 'LO' terminals gave me problems (both the front and the back connectors!). They refused to go all the way into the meter (34401A). AFAICS it did not hamper the measurement but I didn't like it all the same so I removed ~8mm from the black plastic tube on both black connectors. That resolved the issue; they now go in both easy and all the way.

There is a reason that they were under 13 euros including shipping, they do their part, I do mine :-)

I found that the genuine, €30+ Keysight leads that I got for this meter the other week also do not go in very easy; I have to hold the instrument while plugging them in. Maybe my meter was never used with leads  ;D

This is not a buy but an early Christmas stocking stuffer from a fellow EEVBlogger.  I won't name the blogger, they can do that if so inclined.  I have a couple pair of Vetus tweezers that were the nicest I have and some crappy Harbor Freight tweezers that I will be happy to get rid of.  These are of Duratool manufacture and very nice.  I actually grabbed and removed a single arm hair with the curved tweezers, something I simply can't do with the crappy ones I just tossed.  Once again, I want the blogger to know that I appreciate the gift very much and am grateful for the kindness that came my way.  I am usually the one giving.  It is nice to be on the receiving end once in a while.

I recently bought some kelvin clips also and although they have gold plated banana plugs, the plugs swivel which seems to defeat the purpose of using banana plugs- large amount of self-wiping surface area for contact. I am thinking I should perhaps solder them so they can't swivel?

Paid 50p at the Kempton Park radio rally...  Now I have to find a use for it.

The rotator seems to have three wires...  Any clues?

(I wonder if the hand is radioactive?)  Seems to be Bakerlite or similar.

I'm thinking the A,B,C wires are windings around a common rotor... each 120 degrees apart.... so I need to generate three voltages to make it point in some direction...

It is a regular synchro receiver, google it, you will find information to make it work. Digits on the dial might be radiactive, yes, you will  need some geiger or dosimeter to check.

Red yellow and blue connect to the indicator, and you apply 24VAC ( probably 50Hz, though this could also be a 100Hz or 400 Hz indicator, limit the current and start with 6VAC as test and a 100R series resistor) to the black wires, and as you rotate the centre it will move the pointer on the indicator to follow it. Simple resolver remote indicator there, the Ac is exciting a coil in the head and the 3 coils are transmitting a 3 phace voltage with a magnitude and amplitude for the indicator that follows the phase of the excitation coil.

Show pics of the back of the indicator, and any manufacturers plate there, that is a really old Smiths instrument, probably made around 1964.

My 3kva variac came in the other day.  I posted about this already, but here's an actual pic of it:

(http://gal.redsquirrel.me/thumbs/lrg-4147-dsc_2779.jpg) (http://gal.redsquirrel.me/images/other/random/dsc_2779.jpg)
 
I want to start playing with mains powered PSU design so figured this is a good way to rev the voltage up slowly during testing phase, and overall just to give me a source of variable AC or DC (if I rectify it) power.

I also recently ordered a 1500kva 120v to 480v transformer to go with it.  I did not need 480v and that's getting into seriously dangerous territory if I'm not careful with that thing, but I wanted it for the isolation.

Received some HV caps from HFO (Poland) so managed to finish re-capping my old PSU. Voltage rails seem to be within tollerance now so I'm giving the old girl a face-lift with a new alloy front together with 4mm banana sockets (they replace the 2mm sockets that were on the plastic cover - seen lying on the bench). I installed a voltmeter to monitor the output but to have one for each rail would take up too much space so instead there's a rotary switch to flip from one to another. I don't really need to monitor them all the time anyway. There's no current limit on this PSU but I have several others that do, this is a plain vanilla voltage supply.

I don't really have a way to measure that (clamp meter is probably too slow to pickup anything) but it does do a nice "tick" if I plug it in while it's on.  ;D  I was trying to see if it causes the lights to dim, but could not notice anything, but I heard a UPS in the other room go on and off lol.  It may possibly have some kind of inrush current limiting too.

Well wheres all the new purchases from Kempton Park Radio Rally today then?

There were plenty of people buying things... I saw someone walk off smiling with a very crusty oscilloscope.  There was a stand with some interesting old stuff but the stall holder seemed to have high expectations of prices so wasn't selling much.  I also saw a lot of people buying heat shrink tubing!  And the Rigol-UK man said he had sold a few 1054Zs.  (I *maybe* intend to buy a DMR handheld to tinker with... but will use ebay.) Oh and I looked for a 6N7 but couldn't find one. (I was told that they were being bought up at high prices by the cryogenically frozen cable crowd).

I shared a table at Kempton Park on Sunday with a friend of mine.  The rally was quite busy with more test equipment than usual on offer. Prices ranged from reasonable to eye wateringly expensive stuff. I was offering my surplus test gear as usual & sold everything I brought except a Solartron 7060 DMM.  I do mean every piece of proper test kit that I brought along.

Most people there seemed intent on buying IF prices were sensible. I guess my pricing was which is why stuff sold.

My plan was to sell & not buy anything but I failed miserably. I bought a few of the Schaffner filters used on the Solartron instruments for £2-50 ea. These are always failing & really expensive new. I also bought 3 large boxes of assorted ICs. My guess is ~500 tubes - most part used - but still a potentially useful collection. Apart from test gear I also collect semiconductors an the basis that these will be very useful one day to repair something.  The car was almost as full coming home as when I left. At least ICs are easier to store.

I hope that this is not inappropriate but I had it listed at £40. It has all the options fitted & is working but not calibrated. My guess is it was last calibrated a very long time ago. These are still nice to use with a decent LED display. I am keeping one for my spare DMM stock. If you are interested then drop me a message & we may be able to do a deal.

Precisely; ARM "DSP" extensions are really a toy. Actually, you don't even need to use assembly in certain architectures (I am familiar with TI's C6000 DSPs), although actual microprocessor-based DSP applications are a dying breed...

If you don't mind me asking, how much was the Time Electronics 5075?

They look like a decent meter and seem to fly under the radar of people because they're not a "big brand" I've used one of their resistor decade boxes and process calibrators (well volts / mA source) before. The process calibrator was simple but worked and seemed to work quite well.

Mine was £350 all together. I've only used it for a few hours so far and have no idea how it compares to other meters on the market. I mainly bought it because I wanted something better than 6.5 digits and I trust the Time Electronics brand. I have a bunch of their stuff and each one is absolutely bomb proof.

All I need is a decent GPIB adapter and my volt-nut journey shall begin!

If you don't mind me asking, how much was the Time Electronics 5075?

They look like a decent meter and seem to fly under the radar of people because they're not a "big brand" I've used one of their resistor decade boxes and process calibrators (well volts / mA source) before. The process calibrator was simple but worked and seemed to work quite well.

This endoscope: https://www.amazon.co.uk/dp/B01LYNHJQO/ref=pe_3187911_185740111_TE_item (https://www.amazon.co.uk/dp/B01LYNHJQO/ref=pe_3187911_185740111_TE_item)  which was on offer for just £5.09 on Amazon's 'Today's Deals'. Can't quite think what I'll do with it but at for a fiver I thought why not? Now you can all tell me where I can stick it :)

I bought something similar a few years ago, and they are very useful for 'non-bore' things too. Like PCB examination.
Tip: dissect a few old CDROM drives. A small lens from those can be stuck on the end of the borescope camera with blutak or sticky tape, for extra magnification. It's really quite impressive, for the price.

I was browsing the wares at my favourite local surplus/recycled electronics shop when I spotted a familiar shape. Checked it out. Tag said "USB Speaker $10". I knew better. Offered $5 and walked out of there with a Spyder 3 Elite colorimeter. Sadly the OEM software is licenseware and the original CD with key is long gone. Fortunately there are some decent free alternatives (HCFR Colormeter, DisplayCAL). I'm calibrating my main monitor with DisplayCAL as I write this.

Nice catch! It would have been somewhat hilarious if someone did happen to buy it as a USB speaker, only to return it because it doesn't work.

In my message from october 30th I covered the need for reworking my bench console using acrylic glass:
https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/msg1336492/#msg1336492 (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/msg1336492/#msg1336492)

I took all your comments to heart and recently received my order of 4,4m heavy, item-compatible aluminium system profile 40mmx80mm cut into several pieces for building my new bench console support.

"Heavy system profile" means that there's (necessarily) only the slots not being filled with aluminium:
(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=368748;image)
That results in a weight of 4,5kg per meter. The package containing the profiles was 20kg and the postman had to carry it upstairs to the first floor..   >:D

I also ordered some mounting materials and did a partial test mount in the corridor:
(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=368750;image)

The dirt on the carpet is due to cleaning up..  :)  -cutting and flattening cardbox packages of items received in the last 4 weeks. I already have put them in the paper bin outside so it looks clean and civilised again.  :)

I have to wait some more weeks to rebuild my bench console because of my arm (broken 6 weeks ago) isn't capable of being used for heavy loads already. But I'm working on it.  :)

I bought an Aneng AN8002 from eBay a few days ago as a result of an EEVBlog video.  My initial reaction was it a very nice multimeter for the money.  However, mine arrived defective, not too surprising given the low price and origin.  The defect was that mV range failed to zero.  Instead, it continually increments with no probes attached.  The other ranges and functions seem OK but I did not do much additional checking as I immediately requested a return for exchange from the vendor.  The vendor insisted that I send pictures or a video so they could evaluate the problem!  All that for a $17.00 meter!  I did take a video of me turning on the meter and switching thru V, mV, Ohms and Hz.  I am waiting to hear their response. 

I am awaiting delivery of a Bryman TM235.   Other equipment includes an isolation transformer, an old Staco Variac (about .7kVA), a Tek TDS 210 digital scope, another old analog Tek scope (4Ch, 150MHz), an HP 5316A counter, a couple of power supplies (Universal model 6050A, a GW Instek GPC-3020), an LCR meter (M4070), an Agilent U1731B LCR Meter, ($40 at a hamfest), a Blue ESR Meter (kit), and a bunch of dud Ham radios to be repaired (oldies but goodies) and miscellaneous dud scopes the I'd like to get running after I finish my lab and restock my brain.  I also have a few old multimeters that Dave would have no respect for and I am glad I watched his reviews.  Otherwise, I am sure I would have blown myself up at some point.

I am an (semi) retired old timer on a limited budget trying to assemble a usable test equipment lab on a shoestring budget.

My intention is to be able to do repairs on old equipment that I can resell.  I am pretty well versed on old technology but am interested in getting up to speed on SMD and other new technology as far as I can wrap my old brain around.  I recently obtained an Amateur Extra ticket (after a 40 year lapse).  My background was in engineering (mostly mechanical) and for the last 25 years, a PC computer programmer/developer, mostly self-taught (BS - Physics).  I did quite a bit of homebrewing analog ham radio equipment prior to going off to college, which few current hams are interested in.  I should have gone into EE or computers but that wasn't where my ambitions lay (unfortunately).

Three small enclosures, bought from China https://www.ebay.co.uk/itm/100x100x50mm-Aluminum-PCB-Instrument-Box-Enclosure-Case-Electronic-Project-DIY/263189846364?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 (https://www.ebay.co.uk/itm/100x100x50mm-Aluminum-PCB-Instrument-Box-Enclosure-Case-Electronic-Project-DIY/263189846364?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649)

Cheap at only £5.75 each, and surprisingly well made. I needed just one for the DC Power unit (shown) but I bought two extra. It was a tight fit but I wanted the smallest possible enclosure, and the aluminium case acts as a heatsink. Tested it for 2 hours @ 35w and it didn't even get warm. I made a thicker (1/4") endplate because I needed to cut a very large aperture for the power unit and the thicker plate offered better support.

Only issue was that the seller seemed to think a plastic bag was the only protection necessary when posting, as a result the corner of one got slightly bent.

Got a Racal Dana/Thurlby Thandar supply to burn in voltage references, because the DP832 is wy to loud to let it run over night and I needed a second supply anyway.
And I also bought a bunch of parts and I got wood screws instead of 47uF 16V :D I immidiately wrote them and got as a response that they will send me the caps free of charge.

You have floating high impedance inputs in your most sensitive range, this is not a valid measurement situation, one should not expect it to read zero (especially in the most sensitive range) when you are not making a valid measurement which would produce zero.

Some meters are less susceptible than others to displaying these effects, the 800x range isn't one of them.  Not that it really matters, because, as above, it's not a valid measurement.

If it didn't zero (measuring volts) when you touch the probes together you would have a problem.

Even when shorting the leads together you can sometimes get a very low reading as the leads themselves will act as aerials and will pick up stray signals from nearby mains cables etc and  my 6.5 digit meter will often display around 7mV and maybe more, with the leads shorted if I move them closer to an cable carrying mains voltages and these voltages have to zeroed out on the meter so it will ignore that amount when actually using the mV range.

Thats not a bug, its a feature..

All my good meters as well as my scope in the lower ranges do that too. Those voltages are actually present at the inputs.

One interesting phenomenon is the fact that LEDs generate microscopic voltages when light shines on them. (A colored LED will be most sensitive at the same frequency range it emits) I don't know if the Aneng would be sensitive enough to detect that but it may be. Give it a shot!

Thanks, I hadn't considered that as I never had a meter with a mV scale.  Just today, my friend who is a solid state fabrication technician suggested the same thing. The range does zero out so I guess the meter is OK.

VA015MX500, variable 15 VDC 5A
TD15-250, OP AMP dual +/-15VDC 2.5A
B15G100, 15 VDC, 1A
B9G100, 9VDC, 1A

They all work and have low ripple.  Not sure what I will do with them but I do have a project that the OP AMP dual power supply will work great for.

Are you suggesting that the local furniture store that's had 'Lost our lease, huge sale' signs up for the last ten years is lying?!!

I don't even think you'd be allowed to do that around here. It's not even a subtle lie either.

Although, they might be referring to a lease on another property or their previous store, in which case it would technically be true if they also had a huge sale. The very fact that they would continually have a huge sale makes it impossible to establish whether they ever actually had a sale to begin with.

Sadly there are a lot of shops that are always having a sale, one in particular is a bathroom store, part of a large chain of bathroom stores and right opposite a large police station and they have had a permanent sale of one sort or another ever since they opened and thats been about 6 years now and they seem to get away with it.

I don't think having a continuous "sale" would be prohibited, though they're obviously being a bit creative with the truth there, but saying that you lost your lease when that's not the case could be seen as false advertising. Though this might obviously vary wildly between jurisdictions and countries.

Saying you're having a sale, with prices actually being the same as before when you didn't have a sale is actually prohibited in a lot of places, but I guess the grey area is when you're never not having a sale.

This eBay Global Shipping Program is killing me. If things were to shipped normally, you would be able to recover the VAT paid when importing the goods. However, under the terms and conditions of the Global Shipping Program you're only allowed to participate as an individual, therefore making it impossible to recover any VAT. That vastly increases the price of many objects. I guess it's some clever accounting trick which makes eBay money somehow, but it's driving me nuts.

I'm also seeing a few HP listings with everything in order, except the title being something like "HP Printer Cartridges model no something something". The rest seems to check out, and shouldn't provide the seller an escape if he ships you a few printer cartridges, but I'm not sure. Is this some sort of known scam?

I figured that maybe they'd misplaced (lost) the paper detailing the lease terms - in a very pedantic sense such a thing could be considered 'losing your lease'.  Regardless, I don't shop at such places.  More furniture = less room for other acquisitions.   ;D

Actually I was just screening the small ads for some cheap probes and I was curious as to what the specs of the old scope were. The pictures were all a little out of focus but since the probe connector read »Tek« and it was more or less around the corner from where I live, I thought: Why not check it out!

The scope itself is funny. It weighs next to nothing, has a small 6cm / 5cm screen and is only 183 x 85 x 200 mm / 7.2 x 3.3 x 7.9 inch in overall dimensions.
The tube needs some minor adjustments and the device will most likely be modded into a vector display or serve as a movie prop in the future.
On the other hand I would offer to donate it to someone in need of a very basic one channel scope.

A random slab of metal I have laying around, used a piece of tungsten for a while but people kept saying it'll shatter so stopped using it. Think I might get some hardened tooling steel at some point. For the softer non-stick action I also have a 2 cm diameter teflon rod on my desk at work, been meaning to install a handle on it.

Why do you want something hard? That's more likely to shatter. Having something that isn't too hard also saves the copper head.

A lot of metals will actually work harden sooner or later anyway.

Well, the piece of tungsten was actually previously used as a sort of press platen.

But it really depends on what you're hammering away at, for softer things I always put scrap MDF or aluminium underneath, but if it's really to shape something there's no point in having a soft surface underneath, it'll just sink into the surface of your anvil. The "hard means super brittle" thing is pretty much wrong, it really depends on the quality of the material and its exact crystalline structure. There are tooling steel alloys that will happily take brutal impacts all days and still flex under load without instantly breaking when asked to. For example, the striking surface on a blacksmith anvil is actually hardened steel, the regular cast iron would shatter, mild steel would deform, but put a slab of hardened steel with the right hardness in there and you're set for life.  :D  Things aren't always as straight cut as most people seem to believe.

Sure, I'm obviously simplifying matters for the sake of the discusison. However, thinking about what you use to interface with what is a good idea. Considering you have a copper hammer, you don't seem too interested in super sharp shaping capabilties, and it might be a good idea to pick something more foregiving to make it a bit easier on the tool. If you start beating on hardened steel with that, the tool will show it.

Also, pressing and hammering aren't quite the same thing when looking at the stresses :) I don't think I said hard means super brittle, but there certainly is a correlation between hardness and how brittle something is. A lot of material science is aimed at hardening materials without making them too brittle. It can be done, but isn't what most materials like to do naturally.
Title: Re: What did you buy today? Post your latest purchase!
Post by: HalFET on November 14, 2017, 09:20:07 pm
Well, first of all I don't actually intend to use this hammer to smash things to bits, for that a good old steel hammer is still the best choice, if you're in a non-explosive/flammable atmosphere at least. But for softer things I use aluminium scraps or MDF as stated before, but even with aluminium you got to be careful which alloy you use, some are pretty damn hard. Additionally the entire point of a copper hammer is that it's softer than the material you're hitting.

And about press platen, actually you absolutely do not want brittle things for those. Otherwise you might end up with some interesting problems when you run into non-flat press books.

No phones, no laptops, no point-and-shoots, and no HiFi players/amps.
Sony still makes some very decent headphones, business oriented products and is still the world's No. 1 optical storage media manufacturer and No. 1 high end camera sensor manufacturer.
I'm totally fine with my two Sony mirrorless cameras, and some business gears (IC recorders, commercial projector, etc.).

I don't want to jinx it, but I hope this eInk paper will not fail me.

Whats wrong with their amps? I like mine, have had it for 3 years.

Heavily overpriced amplifiers and DACs with ambiguous specifications.
Their players are basically just joke. The S-MASTER is just 1 bit sigma delta, developed to save power (no opamps anymore).
For whatever reason, Sony decides to market DSD/S-master direct play technology, which is basically dumping DSD stream to RC filter then to headphone directly.
And the worst thing is that the audiophile market actually agrees with it. Don't know how much money they spent on bribing HiFi editors, though.
I have a couple S-master players, and I have to say they did a great job. It's hard to build a pure digital amplifier with such high audible background noise. They must have violated all design rules.
They do have some non-S-master devices, such as PHA series headphone amp+DAC combo, and they are some of the best specced devices, just the price is quite bloated, at $999 in US.
And I highly doubt if they have any knowledge in system engineering. PHA3 runs HOT, even hot to touch, it burns. Only Sony will sell hot to touch consumer, portable, supposedly pocketable gears.
Oh, they know that. They have a high temp sensor that will inhibit battery charging to prevent a fire -- supposedly it has happened somewhere in their R&D process. And they didn't reduce its power consumption.

They have some really good headphones, and that's it.

On my amplifier, which is a receiver to be specific, i've never noticed noise on the headphones. I have 5 amps (and or receivers); Onkyo, Pioneer, Sherwood, Sony and a semi vintage BSR of all the BSR is my favorite, though the Sony is my second favorite.

I bought a Sony receiver once. If you turned the volume up past 40% the "protection" circuit would kick in and shut off the audio. I just put up with that because I lived in an apartment and didn't really need to be playing it loud anyway. After a couple of years it developed a habit of latching the volume control motor when you pressed "up" on the remote. You would have to quickly walk over and turn it down manually. Coincidentally, the "protection" circuit stopped working at the same time. This resulted in blowing a fairly expensive speaker. I ordered a different amp to replace it and when it arrived, the Sony went back in its box and into storage where it remains to this day.

I once came across a top-of-the-range Sony FM tuner, being used as an off-air monitor at a BBC studio. It was intermittently distorting. It turned out to be a design flaw - the OPAMP driving the final audio output was biased only by the leakage through the electrolytic capacitor on its input, so its DC operating voltage was prone to wander, sometimes provoking clipping.

We checked the circuit diagram, and this was obviously how it was 'designed'. There were DC voltages marked at key points, and sure enough, the voltage at the left & right channel OPAMP inputs was several volts different.

And nobody noticed, and nobody checked it. I wonder if it was ever tested over its specified operating temperature range?

I'm more into headphone gears, so here amps mean HPAs.
Just check out their spec. No THD, no SNR, no nothing, just beautiful marketing BS.
Check out this one: https://www.sony.com/electronics/audio-components/ta-zh1es/specifications#features (https://www.sony.com/electronics/audio-components/ta-zh1es/specifications#features)

Specs only say power output @1% THD. That's rubbish.

So would SNR capture the level of hiss with no input? I bought some Kanto amp/speakers and they were completely unusable due to hiss. Now I'm not surprised they don't state SNR in the specs.

Swapped them out for an Alientek D8 and its far superior (quoted SNR of 100dB, classD but MAX9722 for headphones). Some hiss is still present, but the amp is much smarter and will shut the output off as soon as no input or 0 volume is present. So hiss is not noticeable (wonder if sony figured that out). I can't really grasp why you'd use classD for headphones, unless you are conserving battery.

The one in the middle is some ~24awg thin ones, probably 15m or more in length. The bottom one is cat5 something...most likely for ethernet. They are all for $5.  8)

- and a vintage (1953, it's what I get on the date code) General Electric 7-2584a dual band pocket receiver for 2 bucks :D It was quite dusty when I saw it and I had to do a bit of cleaning.

It is a GE 7-2584 that can be found in several eBay listings. The date code may well be 29-March-1985 but given one of the photographs on the internet says it is "Made in China", that puts it well into the 1990s or early 2000s.

The first transistor radio, the Regency TR-1 (https://en.wikipedia.org/wiki/Transistor_radio#Regency_TR-1.C2.A0.E2.80.94_the_first_transistor_radio), was released in 1954.

Okay, thanks for the info. Yeah, it's probably really made in the late 80's as cdev said. Anyway, it was a really good bargain.

I was after a Rb standard to feed 10MHz into my Racal 1998, Siglent 1025, and Tek scope, but I spotted a slightly beaten-up (but still functional) Racal 2202R so bought that instead.
It has two 10MHz outputs on the rear, and two additional unpopulated (blank plugged) outputs. Anyone aware what is required to get those extra outputs functional?

I will build a kind of shelf frame made of wood to mount them into because I don't want to drill a large number of holes into the wall to fasten every depot individually.  I only rent the flat I'm living in.  :)

I think what you're seeing and thinking is wasted space is actually the side of the cabinet(s).  We have one of those at work - it's a lazy susan with the cabinets stacked on top, offset so that they meet side to back.  The blue wall to the right (by the open drawers) is the side of the back facing cabinets, and the blue wall in the center is the left side of the  right facing cabinets with the open drawers.  I hope this makes the arrangement clear - it would have been much easier to see if the picture had been taken from a slightly higher angle to make the top visible.

It's a pretty cool storage idea, but I shudder to think of the mess if it ever got knocked over.  The one at work seems a bit top heavy and tipsy to me.

I'm referring to the center. By stacking them together this way, you're bound to have a void. Obviously, the turning radius on the outside also cannot be used for other things, not without losing the turning capabilities at least.

I'm not saying they can't be useful or practical, but the limited space here has trained me to seek out inefficiencies in storage designs ;D

Ahh, gotcha.  Yes, there is a 6 or 7" square void in the middle of the one at work.  I suppose one could rig up something to store lengths of heat shrink or something similar in there...

Oh, could be 70's, possibly.  But, NO WAY 1953!  It would have to have TUBES in it to come from that year.  And, I'd love to see how they packed the tubes and batteries in that little thing.

I'm not really sure, it just says in the yellowish sticker paper in the battery compartment: "DATE CODE: 5329"
It is a GE 7-2584 that can be found in several eBay listings. The date code may well be 29-March-1985 but given one of the photographs on the internet says it is "Made in China", that puts it well into the 1990s or early 2000s.

Yeah, transistor radios started to pop up in Oz around 1955, & by the late '50s were everywhere.

They were pretty much all Japanese though.
The first Australian made transistor radios were not pocket radios, but just about the size of the smallest valve portables.
They had room for big batteries, so were a bit cheaper to run than the really tiny ones, but all the "trendies" of the time the time wanted  pocket " transistors".

I'd date the first dual wave transistor radios to about 1961 .

I just received a used LakeShore 120CS current source in excellent condition.  While made for use with temperature sensors for handling liquid helium and nitrogen, its selectable current source outputs of 1, 3, 10, 30, 100, 300 uA and 1, 3, 10, 30, 100 mA make it useful in test equipment analysis and other electronic purposes.  It can apply up to 11 volts output to achieve those currents.  After I calibrated it I measured its typical accuracy as being 0.03% or less.  Its detailed specifications are attached.

A picture of its circuit board is attached along with front and rear panel pictures.  The IC's in it include:

   LM336BZ2.5  2.5V 20 PPM/C voltage reference
   AD820AN  Precision R-R FET input op amp
   TLC374CN  Quad analog comparator
   LT1010CT  +/-150mA output buffer amp
   7815CT & 7915CT  +/-15V regulators

It includes some 0.02% resistors for the different ranges.

I'm happy with the purchase!

I found these Knipex precision wire strippers for around half the usual going rate on eBay, ordered one (smaller 12 12 02 model) because I was getting frustrated at manually stripping PTFE wire since the normal $20 jobbies from Jaycar/Bunnings wasn't cutting it....literally.  :P

No affiliation with the seller. Don't forget to use code "P5OZZIE" for 5% off eBay Australia, hope this helps a fellow Aussie out there.

eBay auction: #263328629991

Anyone have any experience with these models? The replacement blades look pretty expensive, maybe I should buy another spare set from this seller...

That's a precision stripper, very nice. Except the plastic limit part will be damaged or loose quickly.
You never need new blades, unless you abuse them.

I found these Knipex precision wire strippers for around half the usual going rate on eBay, ordered one (smaller 12 12 02 model) because I was getting frustrated at manually stripping PTFE wire since the normal $20 jobbies from Jaycar/Bunnings wasn't cutting it....literally.  :P

No affiliation with the seller. Don't forget to use code "P5OZZIE" for 5% off eBay Australia, hope this helps a fellow Aussie out there.

eBay auction: #263328629991

Anyone have any experience with these models? The replacement blades look pretty expensive, maybe I should buy another spare set from this seller...

This is what I really want, just placed an order.  :-+

An Airedale Terrier puppy, called Griffin. photo from the breeder - in the silly 'stance'. The little fellow handled the interstate flight well - when we picked him up - he looked like he had been asleep for the one hour flight.

Airedales are great dogs (in general) - they don't shed hair, have a good temperament - even with children, and me!
But any loved animal - cat - dog - is a great thing for your life, they give so much back. :)

Got two sets of decade resistor boxes (https://www.ostron.de/Prueftechnik-Spezialmesstechnik/DekadenWiderstaende-Widerstandsdekaden-VEB-Messapparatewerk-Schlotheim.html) today :)
The resistors are made from "Aurotan 43" wire (Manganin wire) and the casing are made from gray Bakelite.

They are in pretty good shape for 1960s gear.

Here are two photos with the 0.1 ohms box at x1 and x10 measured with a Fluke 79 in 40 ohms mode and zeroed leads.

Received a Racal 2202R today and after preparing space to accommodate it found it's longer than expected. Doh! I thought it had the same dimensions as the 1998  :palm:   Oh well, more re-adjustments required.

This is the Rb version and it provides a 10MHz reference output which I will use to sync the 1998, SDG1025, and the Tek scope so they play together nicely. That's the plan anyway. In this photo the gear has been powered up for 30min, the SDG1025 is using its internal reference (an upgraded TCXO).

Edit: Ok, fully warmed up now I should think after 3 hours. The SDG1025 is using the external 10MHz reference provided by the 2202, it is outputting 20MHz back to the 2202 (which reads 20 MHz exactly - hardly surprising), the 1998 reads a little under @ 19.999,999,7MHz (using its internal OCXO), while the cheap Chinese 8-digit counter is reading 20.000,001 MHz (amazingly accurate for an £8 counter).

How's that DM3058 working out for you? I'm really on the fence about buying one. It seems to do everything I need right now, but doesn't quite have the "want" factor.

I'm a bit concerned about longer term stability too, considering some of the stories.

I don't have anything more accurate to compare it to, but it works fine as a general pupose bench DMM. I had watched a few vids of the DM3068 thinking they were basically the same meter but the '68 having the extra digit resolution. Wrong. The '68 has many more functions than the 3058 in terms of math functions and display, and also speed. It's much faster than the TTi 1604 I have though.

That's a bit disheartening, to be honest. I think I watched every video out there, but most are on the DM3068. I guess you had the same problems. Can you elaborate on some of the differences, maybe the ones you consider most disappointing?

I will attempt a review at some point, but things like the sampling speed - on the '68 you can enter the interval numerically while on the '58 you get three options of fast, medium and slow.. The graphing capabilities are reduced, although the '58 will show a histogram (bargraph) I don't believe it will show the real-time line graphs seen in the '68 demo videos.

edit: and now you just made me go look at it more closely I see the LCD is having issues... a dark patch has appeared on the RH side that wasn't there before... See pic..

I guess that seals the deal, then. With the weirdly densely packed bench multimeter market being what it is, and no real obvious good and cheap models near the bottom, I'm considering springing for something fancy of a name brand. Those are not that much more expensive than their oriental competitors. If you compare that to something like oscilloscopes, the relative difference is much more profound.

I seem to have a thing for AC transformers lately, picked this up at the post office today (it was funny to see their reaction when they picked up that heavy box.  :-DD ).  Ebay purchase:

(http://gal.redsquirrel.me/thumbs/lrg-4170-img_20171120_2037016.jpg) (http://gal.redsquirrel.me/images/other/random/img_20171120_2037016.jpg)

1500va and steps up to 480 depending on winding config.  It's to provide isolation when working on mains stuff, figured I'd go all out in case I decide to get into high power SMPSes and I can actually do a high load test if I want to.  What I want to do is combine this with the variac I bought earlier and build a big AC power supply. Probably in a 4U rackmount form factor and make it look retro with some panel meters and stuff.  To control the variac I'd probably look at playing with a stepper motor and belt drive or something.  I would probably rarely go much higher than 120v but the extra voltage would be available if I decide to go photonicinduction on something.  >:D 

This transformer has a nice hum to it too. When hooked up to the variac the hum intensifies as I bring the voltage up.  I can play with that knob all day.  :P

Yep, those cheap chinese counters are very impressive, mine is equally as close to the frequency displayed on my main proper frequency counter, just not as sensitive though.

I go a broken CityEL/MiniEL from an auction, i did only pay about 600 USD for it. I only had to replace one microswitch to get it to drive again. I need some new lifepo4 cells because one of the old cells does have a to high internal resistance, i can't drive up the hill in front of my house because the voltage drops below the cutoff voltage of 2.5V on that cell and the BMS shuts everything down, which is not too funny on steep road  :-[

Love the CityEl, right up my alley, unfortunately I bet the NZ Transport Authority would not remotely be interested in allowing something like that on the road here, I don't think even Renault got any Twizy road legal (they had a couple of demonstrator models for carpark/track drives but that was it).  I have to make do with my Daihatsu Midget II as the most obscure micro vehicle I could find, still it does come in handy, not many single seaters you can use to move house or take a load to the dump.

Post by: Urs42 on November 22, 2017, 02:26:10 pm
The CityEl is street legal here, it is classified as motorcycle but you need a car dirvers license to drive it. The good thing is that nobody at the motor vehicle inspection station knows how a such exotic vheicle should look, and i guess that they do not know much about electric vehicles.

They will only look for stuff like brakes and lights...

Yes. People tend to think of Ikea as selling crappy furniture, but that's because they only buy the cheapest stuff. Some of their slightly more expensive stuff is quite nice and good value for money. You can spend a lot more and end up with a lot worse.

A ferrule crimper and ferrules are something I still have yet to get, though I'm moving closer.  I've recently dealt with stranded wire and euro-style terminal strips a few times around the house, and wished I had something to constrain the loose strands...  *contemplates opening Mouser, DK, Amazon & McMaster Carr sites...*

I recently got a UT210E also. It's nice to have the NCV which beeps to show voltages in proximity in a sort of graduated manner.. That as well as the 1ma clamp current measuring capacity are very nice to have and both seem to me they will help make the hobby safer. In the past with my UT61E for example, which doesnt have NCV I don't just start probing everything when I open up a device and apply power but with the UT210E I have been - as its so easy to just scan around with its tip and its good..You just say, okay, there are voltages here and here and here, that I should know about. Thats just really good as no thinking or examining the layout or schematic whatsoever is required to do that,

On the way is an Aneng AN8009 to go with my AN8008, the -9 being a back up in case I leave the -8 behind on a service call and someone keeps it.  I also bought a Canon 75-300mm F4-5.6 telephoto lens and a new camera bag for SWMBO's EOS Rebel T3 for Christmas.  I gave her 3 suggestions for Christmas and  birthday, a Yamaha headset/boom mic for ham radio use, a Quick 957DW and a Brother 1200 x 1200 dpi laser printer.  I am hoping for the Quick and the printer.

Bought a pair of 34401A mainboards for "parts". They are missing the front/rear switches. Not sure why I bought them but at 25 dollars each I figured they could be useful down the road.
The two 1000V relays are already worth more.
Definitely worth the price for the parts.
Every once in a while a broken 34401A shows up on the market and it is good to have donor parts around.

Yeah, those should come in handy for a quick repair. Looks like the right one might be of the newer generation than the left.

You should have asked for the Quick 861DW instead.  :o  >:D

The primary reason is the 861DW has a 1kW output vs. 580W for the 957. Makes a big difference getting things soldered/desoldered without cooking the board IME (lower dwell time). It also uses a cartridge type of heating element + nicer nozzles IMHO (NK series). There's a lot more precision to the handle portion of the 861.

At least they've upgraded the 957 with a brushless DC motor. The Quick Review: Quick 957 Analog Rework Station (https://www.eevblog.com/forum/reviews/quick-review-quick-957-analog-rework-station/25/) thread and the 861DW review by Louis Rossman (there's still photos in the forum as well).

https://www.youtube.com/watch?v=ChujyTV-HME (https://www.youtube.com/watch?v=ChujyTV-HME)

Downside of course, is the 861 more expensive (Louis Rossman's selling it for $271, and Production Automation Corp/Prime Distributing are offering it for $275). Not sure on shipping, but it'll likely be close.

As I'm sure you recall, I do have one of these. So if you've any specific questions, just ask.  ;D

Unfortunately, I come last on the Christmas list.  The 4 grandkids come first, the 3 children and their spouses 2nd and I come 3rd.  At least I rank above the dogs  ^-^.  They just get stocking stuffers.  With cash flow being limited for the list, I am trying not to push things too far.  Besides, I am sure that the 957 is way better than the Yihua 858D that I currently have.  The 957 is $81.99 without tips at Newark/Element 14 and I have tips that I bought for the 858D that should fit.  She actually mentioned the printer herself, that's an upgrade that both of us will use and be a tax write off as a business expense for her.

Understandable.

FWIW, I usually ask for cash and add what's needed to get the item I'm after (my family's clueless in regard to anything T&M related). The only electronics they're interested in are HDTV's and gaming consoles.

I have tried the cash route in the past but she doesn't like it, she says too impersonal.  She gives the kids cash, she won't do it with me.  I simply put bookmarks for what I want on her computer.  She has given me many funny looks and a couple of 'really?'s but I get what I ask for.  She doesn't understand either but that's OK.

Looks like an oilless direct drive diaphragm compressor, so likely around carrier-flight-deck-during-launch noise levels if previous experience with the breed is any indication.  Still, pressluft is handy and if it's only fired up occasionally it should be tolerable.

Yeah, it's loud.  It's also slow - only 1/3 HP - draws about 175 watts.     I think I'll keep it pressured up and see how often it needs to cycle to keep the tank full - would not want to have to wait for it to fill and listen to the loud whine when I need air.   One advantage of the low power is that I can run it off a cheap 12V inverter for car use.

I ordered some pilot's operating handbooks for a few of my things.  Have one coming for the Fluke 8400A, the NLS meter I recently got, the Honeywell 620 from a year or two ago and a Triplett 8035 that's been in the queue for probably two years now (it's a little three digit meter with 7 segment VFD tubes).

That'll last till the first time it needs to refill at three in the morning! :-DD 

I have a Makita MAC700 (an oil type reciprocating compressor); it's really quiet for a compressor.  I was using it to run a small flooring nailer for some work I'm doing on the house, and forgot to shut it off once.  It came to life in the dead quiet of the night about a day later when I was sound asleep,  :o  and I nearly levitated into the ceiling when it did so.  Making sure that it's turned off is now part of the done-with-work checklist.

Just something to keep in mind...   :D

Glad to see I'm not the only one to do something like that.  I left my HF compressor on in the garage, which is the opposite wall of the master bath/closet.  Same thing, went off in the middle of the night.  Boy, was SWMBO hacked.  Once was enough, I double check now.

My personal favorite for small, very quiet, cheap, compressed air.....just purchased 3 of these. $135 each. Now I have a total of 4 of them. The first one has quite a few running hours and still going strong all day, every day. Literally, 7 days/week cycling around 20-30 times per day for around 3 years. Not bad for $135 and being quiet all along.

I can't say that it really has, I just picked it up years ago.  In the early/mid 90s I worked for a company that was based in Liechtenstein (Bal-Tec, spun off from Balzers), and between manuals printed in German, English and French and the fact that we usually got manuals for new instruments in German months before we got anything in English (there's a funny story with one of those and an early translation program, but that's a tale for another time...), I learned to puzzle some bits and pieces of German out.  That's one of several that have stayed with me.

I found these Knipex precision wire strippers for around half the usual going rate on eBay, ordered one (smaller 12 12 02 model) because I was getting frustrated at manually stripping PTFE wire since the normal $20 jobbies from Jaycar/Bunnings wasn't cutting it....literally.  :P

No affiliation with the seller. Don't forget to use code "P5OZZIE" for 5% off eBay Australia, hope this helps a fellow Aussie out there.

eBay auction: #263328629991

Anyone have any experience with these models? The replacement blades look pretty expensive, maybe I should buy another spare set from this seller...

Thank you for sharing this information, I got mine today, together with a free multi-purpose tool (what do you guys call it in English?)

Yeah - fortunately my lab is in a basement utility room that is pretty well sound isolated from the rest of the house. With the compressor running you can only hear it in the unoccupied room directly above it  - and even there it is not too noticeable.

rx8pilot - those California Air Tool compressors look nice.  If it turns out the cheap Harbor Freight compressor is needing to run too much while I'm in the lab - I may relegate it to bicycles and occasional car tire use in our second garage and pick of one of those California Air Tool compressors.  At 1 hp - it must fill that 2 gal tank quickly!

I think the 1hp rating may be generous....but it does fill the 2gal quickly. I have a 7gal, 5.5gal, and 2 of the 2gal - all with the same pumps.

Fast internet.  :phew:

Yes I've known what I've been missing for some time with only 1.7Mb/s max at some ungodly hour.  :--
20-100 Kb/s at peak times has been a PITA for too long on ADSL 1.  ::)

Point-point 5GHz microwave from a new ISP here in NZ.....Bluedoor.
https://bluedoor.nz/bluedoor-wireless/

Now they've not a lot of microwave sites but they're expanding their coverage so give them a yell to see if they can help you. Mine connects to their elevated site near Riverhead (NW Auckland) ~10 Km away.

Got the 30Mb/s plan and 10Mb/s up that will suit our needs just fine.
NO DATA CAP.......yeah ha.  :clap:
Might now get around to watching a few more of Dave's vids.  :)

Good grief I thought you already had much faster services than that? I'm with Virgin and I get the UKs fastest service, 300Mb/s download and 12Mb/s upload with no capping. Problem is though you can only use that speed of the server you connect to is capable of it and many are not.

Many in the cities here do but go 20 minutes out like we are and it's pot luck based on what services pass your gate.
The politics of copper charges have affected the rollout of better services and while we've been patient for years the pressure from 'er indoor's was getting too much to hold out much longer.  :horse:

Yep, Vodafone did a similar dirty trick on us a few years back.

Sir
Your plan 10Gbs/month is less than our now minimum package, please accept the new 80Gb package @ an additional $15/month.

Shit our service was so bad, same as it's been until today  :clap: that we could never use 10Gb let alone 80.

making sure you have the Internet speeds you need to save time
and do more of what you love. That's why we've increased
your speed from 25 Mbps to 60 Mbps at no extra cost to you.

So, go ahead – simply restart your modem to enjoy
your new speed.

What they fail to mention is that monthly rates have increased by well over 50% in the last year or so.
Yep, Vodafone did a similar dirty trick on us a few years back.

Sir
Your plan 10Gbs/month is less than our now minimum package, please accept the new 80Gb package @ an additional $15/month.

Shit our service was so bad, same as it's been until today  :clap: that we could never use 10Gb let alone 80.
One of their fooking NZ directors got his arse handed to him by email, I tell you that for sure !
What was the result, a dead connection?

No but for the last few years we would've been better off with another ISP.

He passed me on  ::) to NZ Chorus whom are responsible and own much of the telecoms infrastructure and also own the HW that gives us data. Trouble was they had a NZ Commerce Commission joint ISP complaint laid against them for their copper access charges for the ISP's. When Chorus lost a good hunk of their profit from having to reduce their charges they sat on their hands and wouldn't rollout the infrastructure improvements needed to keep pace with technology. Can't say I blame them.
Shit all has changed for those of us that live rurally other than newcomers that see a need and get their arse into gear to give us what we need, want and expect.
Go Bluedoor go.  :clap:

Now these guys offer some pretty good packages for NZ with speeds to 256 Mb/s (unadvertised) which BTW I spotted when they were setting the HW up.

With the compressed air remember that the first thing to do is be ruthless about leaks, as those are a straight pouring of money away in both power used to compress air and in reduced compressor life. Ant leaks should be eliminated as much as possible, and if you can install shut off valves every tap off, as they are cheap ( for a simple 1/4 turn stainless steel ball valve, which has a pretty good life as well) and reliable.

Remember as well the tanks need to be pressure tested every few years ( depends on where you live, a pressure test generally is also a requirement for your insurer as well), plus you do need to either have an auto drain valve, or a regular regime of draining the tank every day or when you use it.

Our internet got faster then cheaper here.  We were at 50 Mbs, then the minimum speed went to 60 Mbs without an increase.  It then went to 100 Mbs without an increase.  However, when we ditched the cable tv part of the bill and just kept phone and internet, the per cost of the individual service for internet went from $77 a month to $66 a month.  So when your cable company says you will save money if you bundle more services, they lie.  At least in my case.  For those curious, we had Brighthouse and it recently became Spectrum.  I will give them credit, even in the evenings, I never drop below 100 Mbs and can get anywhere from 102-110 Mbs consistantly and I have seen it has high at 117 Mbs.

Three years ago I was paying $45 a month for the 25 Mbps service, now it's over $80. It's partly my fault for not calling and negotiating a better rate every year when they increase the rates. That's pretty much how Comcast operates. At least this year they increased the speed along with the monthly charge.

Until now, Comcast has had no competition around here, but AT&T has recently completed installing their U-verse in this apartment complex and supposedly there's some kind of deal between them and the apartment management where we can get a good rate. So I'll either be switching or using that to beat Comcast down to something more reasonable.

It came in a fancy box, with a 5 g and 10 g reference weight as well (the 5 g reference shows 4.999 g and the 10 g reference shows 9.995 g). Needs 2 AAA batteries. I think it is very good quality for the price, I can recommend it if you need such a scale:

I could have just as easily posted this in the TEA thread but will do so here.  I was at the local candy store and grabbed a couple of computers, sans hard drives, with Pentium D processors and 4 Gb of ram for 2 for $10.  I plan to put a hard drive in one and dip my toes in the pool that is Linux and see what I can learn.  Not sure yet what to do with the other.  The steal of the day was an HP 3312A function generator for $35.  It needed a fuse and, as you can see, has 2 buttons broken.  The power button presses fine with a small screwdriver and I can use a fingernail to depress the other.  Now I have to do some Google Fu to see if I can find replacement buttons, or maybe someone here has a parts mule that they might be willing to sell me a couple?  ;D

Yes, I meant the concept of switching HV with a string of semiconductors.  Cause I doubt youll be able to equalize all the gate voltages with that HV and steep pulse

If you mean someone standing by the main breaker, say so!!

This was standard practice with anything reasonably "hot", but most transmitters, for instance, do have
quite a lot of personnel protection built in.

Thousands of people in Transmitter sites, over decades, worked safely with high voltage equipment by the application of simple safe working rules.
In my own experience, nobody I worked with suffered severe Electric shocks causing injury..
Two people died in aircraft crashes, & two others in falls.

The "Aiieee! The sky is falling!" approach is counterproductive.
Working with high voltages is much less dangerous than the construction industry

Certainly. A WatchHuman TimerR is quite effective in preventing accidents and keeping each other in check. You are absolutely correct in saying that, with proper procedure, equipment and techinques, high voltage is very safe.

Do they still use padlocks on breakers and doors?

I bought a few things at a large local auction here in the UK and took delivery today. It was an auction for a factory closedown and there were lots of Thurlby PSUs on offer. I got a nearly new PL330D dual programmable supply (32V 3A dual with RS-232 and GPIB) really cheaply, also a Keithley 2000 bench meter and a TTi LD300 load.

https://uk.rs-online.com/web/p/electronic-loads/0535632/

There must have been over a hundred Thurlby PSUs and there were so many they were being sold in lots of 6 or 9 at low prices. But there were a few programmable ones sold separately and I got lucky. I was tempted to buy 20 or 30 more PSUs and sell them on ebay but I don't want the hassle.

Bought this 1:5 video distribution amplifier for £2.99 thinking it might be useful for distributing a 10MHz reference from my Racal Rb counter. Well I wasn't going to be losing much if it didn't work  :)  It's basically 50 Ohm but it came with three 75 Ohm terminators as well. Seems to work OK if I put a 10MHz signal through it from my function generator..

The standard for video is 75 Ohms, but the mismatch won't be much of a problem.

Yes I know - and I guess the reason why it came with these adapters...

Bought a milligram weighting scale:

It came in a fancy box, with a 5 g and 10 g reference weight as well (the 5 g reference shows 4.999 g and the 10 g reference shows 9.995 g). Needs 2 AAA batteries. I think it is very good quality for the price, I can recommend it if you need such a scale:

http://cgi.ebay.de/132225160852 (http://cgi.ebay.de/132225160852)

Does it allow you to use those weights to recalibrate the scale? Also what is it like at the corners rather than the centre? I have 2 scales which are an order of magnitude less sensitive. One of them is great no matter where your load is on its bed, the other gives +/- 2 counts predictably. I obtained the 2x 50g weights separately and used them to recal using the zero and 100g adjustments

But for the price it looks great.

Though sadly this is considered drug paraphernalia by some authorities.

Nope - it doesn't show until it's been powered up for an hour or two. If I select inverse display it doesn't show at all. Must be a heat thing I guess..

I obtained the 2x 50g weights separately and used them to recal using the zero and 100g adjustments

The manual doesn't say anything about calibration. 10 g now shows 10.018 when the weight is in the center, and 10.022 when it is over the cylinder at the side which goes into the case. Should be no problem, because the plastic cover can be placed upside down in the center. But looks like +/-0.2% error, because last time it showed 9.995 g, maybe depending on temperature (it is a bit colder here now)? But tricky to measure. Before I cleaned the reference weight of fingerprints with a paper towel, it was 3 mg more, maybe I should use some solvent, and then not touching the weights with bare fingers.

The LED weight is the same, which means the error is relative. Still good for the price, I don't need it very accurate, but was just interested in weighting parts.

The IPK and its copies change weight due to external influences and tarnishing all the time, which is a problem. They will address these issues by eliminating the IPK as the definition of the kilogram and defining it based on constants instead.

Technically the IPK itself never changes weight, because it is the definition of weight. It's copies do, as they change relative to the IPK.

Frank, how is the Bitcoin miner you built in 2014 or so doing?

I lost interest in the project, because it would never generate any substantial money with the high hash rates at the moment. Would be still fun to do it when I have some more time and feel like I want to finish it.

Resistance decade box - bigger than I thought it would be.

Also, I orderd 1 ltr of MG Chemicals Rosin Flux a couple weeks ago, it got delivered somewhere else (not where Amazon said it was) and I claimed against them for the loss and was refunded. A neighbour brought it round today - took her time! Still, can't complain - I guess it was free in the end..

I looked at a similar one with different colours, but it went for stupid money.

Since missing out on the previous affordable one, I've been seeing opportunities to use one all over the shop  ::)

Today I have purchased my second soldering station after reading about others peoples experiences with different brands etc, and it seems that Metcal is one of the ones to get if possible. The price of them makes it a no-nbo for me but apparently there is one that offers 75% of the performance at a fraction of the price that gets favourable responses so here we go, with a UK plug of course.

I've just been checking this one out and it appears to be accurate across its range. Not sure why there is a 'callibration' sticker on it though - what is there to adjust?

I've seen some stupid prices for these things new - like over £600!

I bought a few things at a large local auction here in the UK and took delivery today. It was an auction for a factory closedown and there were lots of Thurlby PSUs on offer. I got a nearly new PL330D dual programmable supply (32V 3A dual with RS-232 and GPIB) really cheaply, also a Keithley 2000 bench meter and a TTi LD300 load.

https://uk.rs-online.com/web/p/electronic-loads/0535632/

There must have been over a hundred Thurlby PSUs and there were so many they were being sold in lots of 6 or 9 at low prices. But there were a few programmable ones sold separately and I got lucky. I was tempted to buy 20 or 30 more PSUs and sell them on ebay but I don't want the hassle.

So you can expect to see lots and lots of Thurlby dual PSUs appearing on UK ebay in the coming weeks... :)
Hi G0HZU What sort of prices were they going for so we know what to bid the ebay bods ?  :-+

Calibration is not the same as adjusting! Watch the recent Keysight calibration laboratory videos. Clients will do a lot to avoid adjusting their equipment. Knowing the error and tracking it over time is much more valuable.

Although I did change out the handle for a push-in style that brings the tip closer to your fingers (metcal style handle), for precision work.
When you first power it on with the new tip, the temperature readings will go crazy, after some minutes it should settle down.

That will be dead handy for tracking hot spots like shorts on PCB's and parts getting excessively hot. I use a cheap Lidl variant for that and its quite effective in that role.

Looks like Raytek are now part of Fluke (Fluke Process Instruments) and indeed the recommended replacement is now a Fluke branded device. Also, this model is the MX4+ which was top of the range at the time. Going to have some fun playing with it :)

They shipped mine with epacket (few weeks) so hopefully you will get yours quickly as well.

Handle was recommended in another T12 thread, but did require modifications, as I did not realize that some stations are 4 or 5 pins.
So the following had to be done:
- Buy handle: https://www.aliexpress.com/item/Professional-t12-welding-handle-oled-digital-welding-station-modified-handle-FX-9501-handle-silicone-wire-handle/32774926734.html (https://www.aliexpress.com/item/Professional-t12-welding-handle-oled-digital-welding-station-modified-handle-FX-9501-handle-silicone-wire-handle/32774926734.html) The FM2028 handle should work too but would require replacing the connector on it (probably easier than what I've done).
- Change 4 pin circular connector on station for a 5 pin GX12 (https://www.aliexpress.com/item/OOTDTY-Aviation-Plug-Male-Female-Wire-Panel-Metal-Connector-12mm-2-3-4-5-6-Pin/32825541738.html), re-used existing 4-pin jst connector inside.
- Moved one side of spring connection from earth to gnd inside the handle (for sleep detection).
- Connected the last pin (from the NTC temperature sense in the handle), to the board with a jumper wire. This step isn't necessary.

The handle it comes with should still be a good improvement though.

I think i may have gone slightly excessive over this last month,
2, Fluke 8400As in the hope of one working unit.
1, Heathkit ID-22 in perfect cosmetic condition.
2, R9 280X GPUs to exchange for a 580x from a friend.
1, chineseium transistor tester / LCR meter (surprisingly not awful)
The Doors L.A. Women LP.
About 120 dollars worth of general electronic parts for repair or experimentation, capacitors mostly. 

Thats a single month when i have gone completely off the rails.  :-DD
At least the GPUs didn't come out of the main budget.

I love auctions!

Wanted a scope for very long time!  Bought a Hantek 6022B few months ago, very disappointed.  (didn't use on Windows computer, may work better there).

Ultimately, my project had 240 VAC and didn't want to plug my Mac into that circuit!

So, from auction this week :

BK-2542 100Mhz scope with 1G/s sample rate and 4k storage points and usb plug.  Not bad.
TDS-340B With floppy disk, communication port, also 100Mhz but with only 1K points storage and 500M/s sample rate.
HP5240A counter

All calibrated in 2015!

I'd promised wife I'd get rid of one of these scopes but I kinda want to hold on to both of them.  Hmm could I trigger one from the other and effectively get a 4 channels.  Will try!

Finally went ahead and bought a 3D printer, the Cetus 3D Mk.2 to be exact.

Really surprised how easy it is to get pretty good prints, after watching a couple of videos about 3D printers I expected a lot more tinkering  :-/O
I have already printed a couple of my own designs and I have to say it's a great feeling to be able to build complete prototypes in one day, including etching, drilling and soldering PCBs whilst printing whatever enclosures or mechanics I need.
It's been running pretty much 24/7 since I got it yesterday.

This should be the type of paint recommended by others, for light blocking led's in scale models. I am guessing that this is a more goo like black paint.

Getting old and lazy. I bought a 355mm cut-off/chop saw to save myself some tedious hand hack-sawing. Built a rack for my 500-series Tektronix oscilloscopes. The lower two positions will carry my pair of 545Bs, the third from the bottom my 575 curve tracer, the fourth my 551 and the very top rung will carry the 551's power supply unit. For now the frame is brushed down in a phosphoric acid based rust converter. I'll let that dry over night and give the frame a couple of coats of gloss black "Rust Guard" epoxy enamel tomorrow morning.

Nice. But are you sure those little castor wheels are up to it?
You might find it worthwhile to add screw-down pad feet at the corners, to take the weight off the castors when it's left in one place for a while. Otherwise the castor wheels develop flat spots due to plastic deformation.

Also, I orderd 1 ltr of MG Chemicals Rosin Flux a couple weeks ago, it got delivered somewhere else (not where Amazon said it was) and I claimed against them for the loss and was refunded. A neighbour brought it round today - took her time! Still, can't complain - I guess it was free in the end..

I actually experimented with stability when determining the width of the outriggers for the castor wheels. The rack unloaded is easy to tip, though it may not look it perhaps, when loaded it is in fact rock stable. There is a lot of weight bearing down on the center line (most of it coming from the pair of 545Bs at the bottom) and to topple the rack you'd have to leverage that weight over the fulcrum point of the outer castor wheels. Not easy and you'd never do it by accident.

Almost gave myself a hernia loading it this evening. Lots of ventilation here and all of the side panels are easily accessible/removable for routine calibration. Hmm, I was getting nice and toasty sitting on the chair next to this equipment rack just now.

Those Amazon $10/4-pack DC/DC modules are actually quite efficient -- they run very cold, not even warm to touch, while stepping down 19V to 12V, ~1.5A, without any thermal solution, wrapped in electrical tape.

It would be the EMC they're spewing out into the computer case that would worry me more than thermal issues.

Bad news. My previous RX 560 purchase was proven to be wrong. My old R9 nano is not faulty, and the fault was a WiFi card shipped with my motherboard. 15% restocking fee down the drain.

Lesson learned: never buy cheap motherboards from AsRock. I knew $200 for an X99 mobo with WiFi and USB3.1 can't be good, but anyway. It's indeed very stupid to put a $200 mobo in a multi-thousand-dollar dream setup.

Arrived today is a Mediasonic external HDD raid box which I'm using in my NAS setup. I no longer want my HDDs to be in my main computer chassis, so I need to find a place to plug them into.

I did 2 modifications on the enclosure, first by adding a DC/DC module in fan cable to step down the noise, then by adding another DC/DC module to convert 19V to 12V, so I can tap power from my Intel NUC power brick to power my HDD enclosure. The NUC PSU is a 65W unit, and the NUC will never suck more than 25W from it.

Those Amazon $10/4-pack DC/DC modules are actually quite efficient -- they run very cold, not even warm to touch, while stepping down 19V to 12V, ~1.5A, without any thermal solution, wrapped in electrical tape.
I've had a few motherboards from Asrock in the past and they've been OK.

Hakko 633-01 Soldering iron holder

Being a newbie to soldering, I am confused as I find so called "brass" products for cleaning soldering irons, but then later down the page I see the same product being described as "gold" "color" "steel". Looking for a tumbled brass ball, I am having difficulty finding it on eBay. Update: Ok, I finally found a sales listing that at least clearly promises brass, and not steel.

Lesson learned: never buy cheap motherboards from AsRock. I knew $200 for an X99 mobo with WiFi and USB3.1 can't be good, but anyway. It's indeed very stupid to put a $200 mobo in a multi-thousand-dollar dream setup.

Arrived today is a Mediasonic external HDD raid box which I'm using in my NAS setup. I no longer want my HDDs to be in my main computer chassis, so I need to find a place to plug them into.

I did 2 modifications on the enclosure, first by adding a DC/DC module in fan cable to step down the noise, then by adding another DC/DC module to convert 19V to 12V, so I can tap power from my Intel NUC power brick to power my HDD enclosure. The NUC PSU is a 65W unit, and the NUC will never suck more than 25W from it.

Those Amazon $10/4-pack DC/DC modules are actually quite efficient -- they run very cold, not even warm to touch, while stepping down 19V to 12V, ~1.5A, without any thermal solution, wrapped in electrical tape.
Expensive motherboards aren't any better. I've seen people having huge issues with Asus, Gigabyte, Intel and other motherboards. If you get a bad hand, you get a bad hand.

A lot of people seem to be using Asrock motherboards with few issues, so YMMV.

An adjustable isolation transformer. Seems to consist mainly of two regular transformers and a toroid variable transformer. I haven't figured out how they make this work, though. Anyone knows? The beast weights 25 kg, BTW.

The two regular transformers are probably back-to-back to end up with 1:1 turn ratio. I'm not sure why they didn't just do that with a single 1:1 transformer. Perhaps to be able to change the input voltage and/or range.

The auto-transformer (a.k.a., Variac) provides the adjustable output voltage. The front panel knob appears to be attached to the auto-transformer shaft, but it could also go to a pot or rotary encoder and use a servo or similar mechanism to enable electronic control.

Kerry Wong did a video on a voltage stabilizer that used a servo-controlled auto-transformer to control the output.

The knob is physically connected to the shaft, adjusting the position of the roller tap. There's no servo in this device.

It could also be that transformer 1 is a step down transformer feeding a small low voltage variac which then feeds into a low voltage primary on transformer 2 which is a step transformer. This way round I think that they will require a far smaller physical size of variac to help keep the overall size of the unit down?

If anything, at a lower voltage you'd probably need a bigger, heavier variac - remember, as voltage goes down, current goes up for a given power.

OK. That works fine and is certainly simpler having the knob just turn the variac. With the digital displays, I just couldn't tell how far they went with digital-ness.

Being new to soldering, and having to wait for stuff to arrive in the mail, I decided to get four more soldering tips in addition to the one that came with the soldering station I also ordered somewhere on eBay:

As I understand it, the flat ones will transfer more heat over to a flat surface. And I will have to guess that the thin and curved one is for soldering tiny spots that maybe are hard to get at.

Edit: Unsurprisingly, I have a lot to learn about soldering. :)

Actually it is for drag soldering, granted you are correct in that I doubt it is used by many, metcal has similar called a drag hoof. I see most people preffering gullwing or mini hoof with dimples. I use wedges of various sizes for all around general soldering.

I don't know what it's intended for, but I'm using a knife tip like that on my Ersa iTool for connectors and larger straight edges. Has a lot of heat delivery capacity.

Mine has just a flat bevel, not the hollowed out type used for drag soldering. It's more like a chisel tip with only one side flattened. On my other cheap soldering iron I use a regular chisel tip that's a little larger.

But I've also used just a standard round tip, works too. I think it is a bit like art or crafting: a good artist can do anything even with a ballpoint pen, but if you have no talent or practice, you can use the most expensive tools, but achieve nothing.

Bought another USB>3-1/2" floppy drive (well, two actually..). Trying to hack my Tek 3014B only to find the drive I already owned had decided it would no longer read/write a floppy drive. They were cheap, and I needed to get above £20 to get free postage so I just ordered two. I have a pile of PC floppy drives but no way of interfacing them - and the cheap USB option was just easier anyway. So now I can give the hack a try - but first I need to drop back a version of firmware.

Certainly listed as for soldering.
Haako even have a link in the above page to show examples of usage but not how I use them for when they outshine all other tips......SMD passive rework.
No need to fire up hot air to remove SMD passives when you have one of these, simply bridge both pads and wipe the component off when the solder has melted.

Bought (and hopefully receive next week through the xmas package buildup) a B&K 9104 power supply. Needed something that could get to at least 60V at 3A. The 9104 is 0-84V 0-10A (any combo that is 320W max). It's a switcher, so not 'quiet' but not a 30kg boat anchor either :). I need it for testing a higher voltage/power LED driver prototype and a bit of rms/p-p noise on the input is a non-issue.

cheers,

Whatever the stuff is that you're smoking or chewing on, its pretty good stuff because you're seeing a lot more than I am when I look at both the photo of and the real chair in the flesh and I certainly cannot detect any hint of a 4 point harness on it anywhere.  :-DD

The only difference between this chair and a normal office managers chair (ignoring the colour and stripes) is the fact it has higher backrest and the top is shaped rather than going straight and flat from side to side. As a 6ft 4" tall person, I find the extra support for my head welcome. The holes are there for other reasons one of these could be the addition of a adjustable lumber cushion as the one in the attached photo shows and also additional support for natural curvature of your neck when sitting right back in the chair, also shown in the attached photo. I did not buy it as gaming, nor a racing chair but as it was advertised as, and is being as, an office chair.

I wonder if this makes any sense: I bought some used PCB's with automotive i.MX6D chips on it for $15, and took the chips (along with the Micron 4Gb DDR3L SDRAM and Micron 16GB eMMC chips, et al) off the board. The seller was using those as development units for some kind of auto infotainment system and since the products delivered they no longer need to keep that amount of development units. I am having a reballing kit coming soon

Should I resell the reballed chips, or just keep them for myself? The exact part numbers are:


Also, does anyone know how to program Renesas µPD78F1824? Those also came off the same board.

I take my words back. They can't allow both drives to spin up simultaneously. One has to spin up first before the other one. So I bodged another power module to solve this. This time a very beefy one. I found a 200W Vicor Mini Gen2 in my crap bin. It would be better if I have a smaller 1/8 or 1/16 brick module, but I don't. All of my smaller modules are 48V input modules, only the half brick one is 24V input model. After sitting in my crap bin for more than 8 years, I finally found a use for it.
This calls for a 555 timer!

The SoC is $45 new, I don't think you can even fetch $15 on second hand market.
The eMMC and RAM combined may get you $5 if you are extremely lucky.
The GPS, if there's a datasheet, maybe $5.
Others are trash.
I got 14x the RAM chip and 7x of the SoC, eMMC, GPS and everything else in the $15 grab bag of boards. Everything is Industrial or Automotive grade or better. I took four off the boards and three still mounted.

If you can get hold onto a copy of BSP package, selling the board will fetch much more money.
I don't have the BSP. I know that the seller has but he cannot release it to me, even with NDA. So I am kind of on my own here.

Since those powerful chips are so damn cheap, maybe I can practice BGA routing and soldering with them? Maybe I can get a board made for about $50, and if it works, I can create my own BSP. I know for a fact that NXP mainlined the drivers for this chip, so it is very likely I can get stock Ubuntu or Debian armhf running on it.

1. You can, but not with $50 PCB. You need at least 4-mil process for 4-layer, or preferably 6-layer, unless you want to use plugged micro vias.
It would be much cheaper than buying the 4 chips alone anyway. So still worth it.
Quote from: blueskull on December 15, 2017, 10:11:53 am
2. Routing dual 16-bit DDR is gonna be a great fun. When you bifurcate any high speed signal, things get rather nasty rather quickly.
Or can I just stick a laptop memory module onto it? That would be plain point to point connection from the chip to the RAM slot connector.
Quote from: blueskull on December 15, 2017, 10:11:53 am
3. Don't use mainline kernel and u-boot. Use NXP's own one. They have an official BSP if you just want to boot the chip, and a community one if you want to customize it. You will need basics on Yocto.
I don't plan to use Yocto at all. Maybe I will need the kernel if it is the latest version, but I definitely plan to spend zero time on compiling the userland at all and just grab Debian or Ubuntu armhf. In fact the whole point of preferring mainline kernel over NXP's is because of Debian.
Quote from: blueskull on December 15, 2017, 10:11:53 am
4. Prepare at least 16GB of RAM. Yocto for iMX6 fails to compile with 8GB if you don't have swap. It's one of the small things that have wasted me 2 days.
I have an idling server with 128GB RAM and 32 processor threads. Compiling the kernel should be a breeze.
Quote from: blueskull on December 15, 2017, 10:11:53 am
5. Yocto is not very popular in China, expect to ask no one and read a lot of materials in English. Prepare to buy books from abroad. Packt has a few books, one of them is specifically written for fsl-community-bsp (the BSP you will be using), the book is called "Embedded Linux Projects Using Yocto Project Cookbooks".
First off, I am not planning on using Yocto in the first place. Second, I would rather not read Chinese documentations anyway since a lot of the writers of those provide no insight on what is going on anyway.

In fact, for the software, instead of u-boot directly launching Linux kernel, I might place a TiernoCore based UEFI in there so it can launch Linux, Darwin (the underlying UNIX part of macOS and iOS) and Windows.

It was from a seller with a single unit sold as used with a few other items (not a reseller or anything.) Found them while I was searching for 11730A cable. 100% feedback and enough responses for me to trust them.  I have received one of those $250 USD (with that sweet $50 shipping surcharge) ones that was sold as-is, and it seems to work on my cursory inspection (readings are ball park, but I haven't had anytime to really examine it deeply). This one was not much more, and I am able to return it since it was sold as used.  Going to use this new unit to compare with the other, and possibly use the cheaper one as parts for the newer one if I find it's not performing properly.

So.. on Friday I placed an order on eBay for a $19 black sheep leather jacket with free shipping (free shipping from USA of all places), and so.. now eBay today sent me a message claiming that the sellers account had been abused by some unauthorized access or something like that, and that the listing was in error. Paypal have my money listed as "pending transaction" but there is NO WAY to stop it. I have now had to send Paypal a written message, in the hopes of them canceling my pending payment. I was given an email address to try contact the seller, and so I did use that option, but I can't help but wonder if maybe the seller's email address itself is compromised. I wonder if perhaps the seller just typed in the wrong details in his sales ad. Though, looking at the sellers activity, there had been no activity for his sales in months, until just recently.

Moral of the story: If it is too good to be true, it probably is. :|

Damnit, it was a really nice looking leather jacket. :| And apparently some 300 other ppl as well also thought that.

Scored an old school Eastern European P4085 resistor standard (1 GOhm, 10 GOhm, 100 GOhm and 1000 GOhm) on ebay. Actually, it's a resistor "imitator", as from 10 GOhm onwards the measurement reading on the meter is generated through a voltage divider. Given that it was built in 1982 it still seems to be pretty accurate.

1 Tohm at 200 V ought to give 200 pA, but I see 20 pA on the Keithley. How come?
Title: Re: What did you buy today? Post your latest purchase!
Post by: Twoflower on December 17, 2017, 02:05:49 pm
I think looking at the display: "R > LIMIT" gives a hint ;-) Also "Limit: 999.9GOhm" another.

Also The measurement has been finished. So the Megohmmetre does not apply the 200V any more.

And another edit: Be careful. The nominal voltage is 100V not 200V.
Title: Re: What did you buy today? Post your latest purchase!
Post by: TX-RX on December 17, 2017, 02:09:43 pm
The Keithley 487 is just used as an external voltage source for the megaohm meter. Otherwise there is no input connected so it's just showing some random reading that can be disregarded.

Moreover, the limit 999.9 GOhm does not have any effect on the reading. It is just an arbitrary threshold value in order to categorize resistors as "good" or "bad".

I see that there is this handy "U" bit there in that case. :) I had to file down a flat screwdriver to make my own at one point. Unless I remember it wrong, I think recall using that "U" tip to unscrew my water boiler which used to have this annoying sound emitter inside that made a loud annoying beep every time the water boiler was started, and when it turned itself off. So, following a guide on youtube, I very carefully yanked out this sound emitter from the printed circuit board. I had ofc at that point concluded to myself, if only naively, that doing this would not lead to a safety issue re. the electronics itself.

FWIW, those I needed for a couple VW's were typically more expensive than the average IME (couple of late 80's models).

Out of curiosity, what did the sensor cost if you don't mind?

BTW, if you're not aware, you may only need to clean the DPF if that's the actual source of the problem. Far less expensive than replacement.  :-+

Thanks re the TDI forum link, the DPF pressure sensor cost AUS $100 - fitting another ~$100 - you have to take the air box out to get to it.
I have had a 'flush', several 'regenerations' so far. A good look over other parts of the car - intake system etc.
The OBD gives a pressure fault, the original manufacturers DPF (Merc) part is about $3,000.
I travel quite a bit to the country - most weeks I will do about 200-300km at ~100km/hr so its not the usual driving style problem. To be fair the car has done ~160,000km in 6 yrs - so to be honest it is probably just 'buggered'. There is a local AUS guy who makes some equivalent DPFs - I haven't heard back from them if they do my model. :blah:

I love the sheer build quality of this meter, it is my first Fluke hand held meter and I doubt it will be my last if this is a typical example of the brand. My Bside meter is also very rugged and feels like a brick but it is no match for sheer weight and toughness of the Fluke.

I'll be passing over to my son so he can do the white infill on the "O" on the handle for me as he did on the Bside to aid the correct selection of the function to try and prevent shoving 200V into the Ohms section directly opposite on the rotary switch.

Today I received this Fluke 25, complete with its hard carry case, manual and leads, hopefully I'll be able to get a case from a Fluke 27 an swap cases over to bring the extra 2 functions into play as well. Never really quite appreciated just how large this meter is in reality, I thought my Bside was big but this dwarfs it apart from the display.  :-+

They are quite brick like, aren't they?  You've gotta love a bludgeoning tool that can also measure resistance, current and voltage!

I have a Fluke 27 F/M.  Besides  bludgeoning tool, it is great for bicep curls.

Finally got my Aneng 8008 today ... my goodness that thing is tiny!!!

But I'm super happy with it, I plugged in a spare set of Brymen 235 leads I bought especially for it (gold plated tips make all the difference imo) and boy does it latch fast! makes it superb for doing continuity testing and for mucking about in my study - It allows me to leave my larger Brymen and Victor DMM's in the workshop.  8)

I did the same thing and I like it enough that I got an 8009 on Black Friday for $19.99 s a spare for work.  Waiting for it to show up.  Just need another set or 2 of the Brymen leads that Frankie sells.

I never knew that the 27/FM was produced in the same form factor as the 25/27. The only ones I have seen have been yellow and I'm pretty sure they also had the bumper around them as well. What actually id the difference between the 27 and the 27/FM?

I think the difference is the FM is a true RMS meter.  If I am wrong, please correct me.
EDIT:  The grey cased FM meters are true RMS, the yellow cased aren't.

Post by: Cubdriver on December 19, 2017, 05:29:17 pm
My understanding (which could be mistaken) is that the grey cased 27/FM measures true RMS AC.  I think the yellow one is not true RMS.

Well that made me check on the Fluke site, and it does indeed show the 27/FM is the same as the 25/27 but in Yellow and there is no mention of True RMS anywhere that I could see on the specification or in the write up speel. In fact the spec as far as I could see is the same as the 25/27 but with the addition of the Min/Max and REL button.

Thanks re the TDI forum link, the DPF pressure sensor cost AUS $100 - fitting another ~$100 - you have to take the air box out to get to it.
I have had a 'flush', several 'regenerations' so far. A good look over other parts of the car - intake system etc.
The OBD gives a pressure fault, the original manufacturers DPF (Merc) part is about $3,000.
I travel quite a bit to the country - most weeks I will do about 200-300km at ~100km/hr so its not the usual driving style problem. To be fair the car has done ~160,000km in 6 yrs - so to be honest it is probably just 'buggered'. There is a local AUS guy who makes some equivalent DPFs - I haven't heard back from them if they do my model. :blah:
Hopefully it's just a clogged pressure sensor then. IIRC, you may even be able to clean this out as well.

Oh, as per cost of the DPF, they go for ~$1300 here (VW P/N; not aware of any aftermarket at this time), so it sounds like importing one would be a less expensive alternative.  ;)

It was designed specifically for the military. The meter itself does have true RMS, unlike it's civilian counterpart. But it also included an HV probe (6kV?), and a custom case to fit it all IIRC (DMM, HV probe, standard probes, spare battery).

That refers to the 27 model, not the 27/FM then, so does that also extend to the 25? The one I have does indeed have the custom case but not the HV probe, the back of the meter also carries a MSHA label (Mine Safety and Health Administration and also states United States Department of Labor but does not mention military apart from an embossing in the moulding at the top.

This embossing states "Meets MIL-STD-810C, method 511.1 procedure 1 explosive atmosphere test"

I just bought another HP 3466A multimeter off of evilbay.  Listed as parts/not working but shown connected to a power supply having an accurate reading.  The seller says the display LEDs don't match the function.  My first one was like that and contact cleaner and vigorous button pushing fixed that.

Ordered a week ago and Fedex delivered today (across the country). BK9104 that was on sale with an additional price drop that brought it from $495 list to $388.

0-84V and 0-10A (any combo valid as long as total output power is no more than 320W). Now I can test a new LED driver design that runs about 150W output and needs to operate from nominal 48V (44V - 60V input).

New power supply will supplement my Rigol DP1116A (0-16V 0-10A, 0-32V 0-5A).

cheers,
george.

If I understand you correctly, the answer is No in regard to the 27 v. 27/FM. The 27/FM was the military variant (it's NSN or NATO Stock Number is on a silver sticker on the back of the enclosure). So it wasn't just for the US DoD, but available to all NATO member nations (if you're not aware of these). Since some 27's use the same grey enclosure as the 27/FM, the easiest way to sort this out is by the printing on the LCD cover. So if it's missing 27/FM, then it's a civilian model. Regardless if it's in a grey or yellow enclosure.

Internally, U2 is a DIP package marked with Fluke RMS on the main board, while the civilian models don't have it. If repair is necessary, it's all PTH construction save U1.

Of the 8025A, 8025B, 25, 27, 27/FM (military variant), the 27/FM is the only version that has the Fluke RMS chip in it (it's the only SMD part in it BTW). As per the HV probe, it is 6kV peak model (P/N = 80K-6 (http://en-us.fluke.com/products/all-accessories/fluke-80k-6.html) High Voltage Probe).

The 25 series are all MSHA rated as they were purpose built for that environment. More recent versions used EX after the general P/N, such as the 87V-EX (http://en-us.fluke.com/products/digital-multimeters/fluke-87v-ex-digital-multimeter.html). They also used red for the boot color in order to easily differentiate it was designed for explosive environments. The current intrinsically safe model is the 28 II Ex (http://en-us.fluke.com/products/digital-multimeters/fluke-28-ii-ex-digital-multimeter.html).

Colors can vary depending on when it was produced (i.e. green, grey, yellow and when they were implemented).

Couple of sources that provide more information:Hope this helps.  :)

I find this statement from the article quite disingenuous, given that I am pretty sure nobody did studies on iris scanning technology leading to cataract - IR exposure maybe, but without more qualifiers (intensity and duration of the exposure, number of years) that is quite an empty claim.

I don't intend to discredit folks that feel strange things when exposed to direct eye exposure to IR beams - the variations of the human body among the population are extreme and can't be "bucketed" into saying technology such and such is "100% safe".

I suspect the issue with Samsung's tech is that the light is focused directly into the iris, Apple's tech illuminates the entire face with 30,000 IR dots instead.

Iris recognition might look cool in the movies, but I think shining focused ir light into the iris a hundred times a day is not such a great idea.

But sunlight is 52% infrared at the earth’s surface. If anyone were that sensitive to IR, they’d feel like they were on fire in daylight — in the shade, never mind direct sunlight. Or anywhere near an incandescent lamp, or any kind of fire.

Nice!

It looks like ex-Kenwood power supply and the brand changed to Texio when Kenwood T&M division was acquired by GW-instek.

Many of them are still used in Japanese assembly lines.

It is a popular power supply because it has very low ripple noise.
If I remember correctly these models were physically heavy:)

Actually IR exposure has been studied, and as you concluded no link to cataract or retina issues (UV does hurt retina).
IR light and IR cameras are widely used in many ophthalmic devices (almost all imaging diagnostics and surgical lasers that require eye tracking). Simply the bast way to have enough light on the eye without bothering the patient or changing the pupil size and affecting eye tracking performance.

Yes, it is only slightly more than half the size of the E3631A (138x124x380 vs 213x133x348), but it is even heavier than the E3631A (9 kg vs 8 kg).

I picked up an HP 5061B Cesium Beam Frequency Standard.  The person I bought if from is the recognized expert with HP rubidium standards.  He sent me the Allan Deviation plot for the 5061B demonstrating almost a factor of magnitude than a standard 5061B which he ran on his Hydrogen Maser.  I've been into frequency-nuttery lately having picked up 6 Rubidium standards and splitting my Lucent GPSDO into two.

He also gave me a backup Cesium tube and a matched driver board along with it.  Needless to say it wasn't cheap but I consider it a great deal compared to those I see on eBay.  It's also it excellent external condition.

I have to find a better counter now, something like an SR620 or PM6681.  A local nut and I are going to run some three-hat experiments on our Cs standards as he has two to my one.

Anyway, I'll load a picture or two along the way.

Like an idiot I thought the 3014B (now a 3054B :) ) had a reference IN for its timebase - it doesn't. There's also a phase difference between the distribution amp's two banks of 4 outputs (1-4 and 5-8), but it won't make any difference for what I do (I think).

That's odd that all the outputs aren't driven simultaneously. Well, as long as you're not timing things at critical resolution between banks, should be alright.

Antioxidants will protect them. That's a symptom I think of low glutathione. You should supplement with antioxidants like n-acetyl cysteine.  BTW, UV is much worse than IR.

Tek 455. 

Belonged to a co-worker, who had it from his (old old) job working for DEC.  (c/w Digital Equipment Corp Canada stickers).  Price was right "Hey, it's taking up room in my basement, do you want it or should I just throw it out?"

Now the big question is:
I'm actually leaning toward the latter of the three because I the Phillips is a tiny bit smaller, and the Tek came from a smokers' household and has a slight smokiness to it. (and no, 50 vs 35MHz, and the additional trigger options aren't really something I need)

Now the big question is:
  • Keep it (along with my Philips PM3216)
  • Keep the Tek 455, give away the Phillips
  • Keep the Phillips and give away the Tek

Personally I'd keep them both and the smell of the smoke is mainly going to be in the document pouch which can be removed and thrown away, or you can treat with something like Febreze to get rid of the odour. There will a little on the 465, but can be given a good wash and clean up and I'd spray a little Febreze inside as well.

I got an Hitachi scope from a house that smoked, and no one in my house smokes but since I did that with the Hitachi I have not had a single mention about the smell of smoke, it has gone completely.

Feeltech FY3224s 24MHz function generator.

Only took 3 weeks to come from HK to UK even with all the Christmas stuff. I didn't expect to see it till after the new year so....score!  :-+
I had a quick play around hooking it up to my DSO scope earlier today and found it to be much more usable than the XR2206 DIY kit i have now and it seems to have had the live BNC jacks problem sorted that I've seen the ones reviewed on YouTube have. It came with a 3 pin UK plug as requested but still only a 2 pin figure of 8 connection into the machine itself. I'll fix that in time though.
I'll have a proper look over it after Christmas. I'm still very new in to electronics so looking forward to that.

Hardline is flexible waveguide. Think of it as coaxial cable on steroids. Typically used for connecting high-power transmitters to antennas, etc.  I have seen it as big as 4 inches (100mm) diameter for high-power broadcast transmitters.  I believe it goes up to 6 inches.

The power amplifier is essentially a "booster transmitter"  You can take the RF output from a "regular" transmitter (perhaps up to 100W) and it will boost it up to perhaps 1000s of watts.  That is how most broadcast transmitters work.  There is a small "transmitter" (commonly called an "exciter") which actually produces and modulates the carrier. A couple of modern UHF TV stations I work with have a transmitter (exciter) in a 1RU chassis.  But then the output of the "transmitter" is fed into one (or many) power amplifiers which simply take that RF and boost it up to the final transmitting power.

Post by: AF6LJ on December 26, 2017, 09:41:08 pm
Richard has it right.
The amplifier with 150W in will put out 2000W.

The hardline besides being used for high power also has much lower loss than regular coaxial cable. If you are serious about operating on the VHF and above amateur bands hardline is the preferred transmission line.  However.....
Connectors cost in the neighborhood of $70.00 US and up.

So I just bought a few Xilinx CPLD, two Spartan-II FPGAs, and a few Microsemi ProASIC3 FPGAs, trying to break myself out of the Intel dependency on programmable logic. Although finding ways to program them can be a bit challenging. (Hopefully my recent confidence in STM32 USB programming would help.) Also for my i.MX233 project I might downgrade the EPM240 display bus demultiplexing CPLD down to a XC9500XL which is smaller yet still have enough I/O pins.

Yep, its been opened and not put back correctly thats a fact. Lets hope that its ok. Lets us all know if its alright when you get it please.

For sure. I plan to film the unboxing as evidence in case I need to return it. Id still be out shipping each way, but I am/was desperate. I later noticed this item was the only one listed by this seller that had the yellow background as well, but the feedback looks legit enough. Hopefully I can run it into town for a cal and its good to go...

[SOLVED: The soldering tip was not mounted properly into the holder] I just got this el cheapo digital soldering station in the mail today, but I haven't figured out how to start using it. Whatever value is set with the round knob, after a few seconds, the display flips to "005" and the soldering tip is cold and never ever heat up.

Either this unit is not functioning (the insides sort of look ok on a first glace, I mean the soldering station isn't empty inside or anything), or I don't know how to start using this. The round button/knob can be both rotated and pressed. I suppose there is some kind of energy saving feature that is at play, but it seems to be working too well.

I don't feel good about posting low quality stuff here on this forum, but it is what it is as they say. I thought a digital soldering station would be an upgrade to the plain soldering iron I think I have stashed away some place.

Btw, I opened this unit before ever using it. I am not qualified for testing electronic equipment, but at least I wanted to look inside to see if there was an effort made to ground the unit and the chassis. It sort of looks to me that this has been done, but I am thinking that the grounding wires are a bit thin. Also, not easily seen, there is a plastic sheet covering the top side of the unit. There is no isolation at the bottom though. The PCB is fastened to the bottom side of the chassis with strips onto four self adhesive sockets in plastic, one at each corner.

I would say that it is almost certainly faulty, shame the pictures are so small, I can't identify the model or anything else about it.

I have just purchased a similar one made by Quicko and sold by AliExpress and I'm very pleased and happy with its performance and it too was cheap when compared to some of the better known brand names.

Problem solved! :) My soldering station is now working as expected! A brief moment after the unit is powered on, the display now show the temperature rising quickly.

So.. I had a closer look at how I had fastened the soldering tip/rod into the holder, and apparently I had mounted the soldering tip/rod wrong! So, apparently, with the soldering tip not properly seated into the holder, the soldering station idled in some off state.

I made the mistake of simply pushing the soldering tip into the holder, thinking I could just insert it and then fasten the locking screw. This was a mistake (!) The proper way to mount a solder tip/rod, is to REMOVE the cap and locking screw, then re-screw those two pieces on AFTER having inserted the soldering tip/rod into the holder.

Electrical service is another matter and I will have to make accommodations for that.
My SB-220 runs fine on 120V for sideband use but the Henry wants 240. :)

I was convinced autism isn't hereditary, but your remark made me check and it seems I was wrong there. It does seem to be quite a complicated subject, though.

Speaking from first hand experience, autism works in very odd ways. They say i'm aspergers and as a result my intelligence is off the charts, Einstein had a lower IQ, but my brain works in such a convoluted way that i can't fully USE the intelligence. At least not in any normal capacity.

FWIW, something like that would have been a Godsend to me as I don't hear words, but music (syllables = notes to me); so I have to figure out the pattern in regard to the context of the discussion/conversation.

That said, it's not a hindrance as it made me relatively OK at pattern recognition.

For disclosure, I try and look at the world from an opportunistic POV. Though quite difficult to pull off, it's much nicer than being a pessimist.

I think there are a few organisations that try to match employers with people with autism. The idea is that autistic people can do things others can't. Rather than looking at the limitations, the idea is to capitalize on the differences. If you see the world differently, that difference can be an edge that others don't have. Quality control and spotting things that don't fit the pattern would be a archetypal example and something some people with autism do very well, while other people struggle to do it consistently.

That seems to be a great idea. Rather than hoping people will have pity on someone with autism, it makes what people are an asset to the company. It's like the guy who invented post-its. At first he thought he invented a terrible glue, until he realized that the drawback could actually be a quality and figured out how to apply it with success.

Btw iirc these days aspergers is not a separate diagnoses, it's another part of the autism spectrum.

Yes one big spectrum, just like colors and thinking about it in those terms imagine apsergers as a shade.
Really its about like Pluto, its not a planet because they say it's not and have an almost obsessive need to fit everything into perfectly neat descriptions. Even that which is highly resistant to definitions.

 ;D Two fine swords.


I predict the plain & simple one will become your favorite.  Moveable parts down around the pointy end are annoying.
After you decide you like the Pentel, I recommend buying a carton full. Such a good thing; they are bound to stop making them.

Here is where I bought a pile of the 0.5mm 2B leads:
  https://www.aliexpress.com/item/5-pcs-lot-2B-2H-HB-0-5-0-7mm-long-size-Lead-automatically-lead-extra/32719945919.html (https://www.aliexpress.com/item/5-pcs-lot-2B-2H-HB-0-5-0-7mm-long-size-Lead-automatically-lead-extra/32719945919.html)
US$1.29 for 5 packs. 18 leads per pack.

Those are unusually long; too long to fit in standard pencils. But it's easy to bulk-snap them in half, which gives about the right length. Put several leads side by side on a sheet of flat paper on a hard flat surface. Press the center with a steel ruler edge. They all snap cleanly. Doing a whole pack at once gives you leads for a year.


Edit to add: My recent comical fail purchase - an LED worklight on a stand, from the local Bunnings hardware store.
The light looks great, the stand works well and has wide-spreading tripod legs for stability. Being LED it won't break any lamp filament if it falls over or is bumped while on. Unlike halogen worklights.
But... when I finally needed to use it, guess what?
You know those LED torches that have several modes, that you must cycle through all the modes with the single button? Where one of the modes is 'emergency blinker', which one never wants and is so annoying to have to cycle through?
Or the type where you cycle through modes by doing rapid power off-on switches, except sometimes the torch forgets the last mode and you get a random one? Also annoying.

Anyway, I turn this light on, and it has an emergency  blink mode. It has ONE mode - blink. I can't find any way to get it into 'just work you f*cking thing' mode. There's only one control - power on-off. Rapid power cycling via that button or the mains plug make no difference, though ONCE it came up in normal-on mode. Cannot repeat that. There is no mention in the 'manual-ha-ha' of any modes, or blinking.

Trying to decide whether to disassemble it out of curiosity (maybe there is a PCB with some mode selection solder pads?), or just take it back for refund/replacement. It was $89, so not a trivial thing to void the waranty.

Sorry, photo is just a still. Would need to make a video to show the blinking.

I also purchased today some more parts to make up another T12 soldering station thats slightly different to the other one to see which is better. To keep it subjective I have the same case and power supply but this time a different control module and the same handle but the system is 5 core while the Quicko one I already have is a 4 core. 5 cores seems to be more the industry norm so I thought I'd check it out, like meters, never have to many irons  :-DD

If anyone is interested I'll posts the photos of the parts I ordered later.

Cheap-ass air compressor. Wanted a light, small footprint compressor for my lab. Tired of hauling my 6 gallon pancake compressor from my garage shop. $40 at Harbor Freight.   We'll see how it holds up...


My personal favorite for small, very quiet, cheap, compressed air.....just purchased 3 of these. $135 each. Now I have a total of 4 of them. The first one has quite a few running hours and still going strong all day, every day. Literally, 7 days/week cycling around 20-30 times per day for around 3 years. Not bad for $135 and being quiet all along.

Yeah, the HF compressor turned out to be too loud for the lab. It’s now relegated to tire inflation duty in our second garage.

I picked up one of those California Air Tools compressors from Zoro at 25% off and damn that thing is quiet- and fast! Perfect for the lab. Thanks for the recommendation rx8pilot!

Cool. So while we're talking about obscurity, some small things I've bought recently.

* An old, old ISA bus IEEE-488 controller card. HP 3643-E2073-66501. Nothing special except that it is the exact model used in a known-working setup of the same HP 5973 mass selective detector as I have. See http://everist.org/NobLog/20170224_summer_vacuum_odyssey.htm#msd (http://everist.org/NobLog/20170224_summer_vacuum_odyssey.htm#msd)
My MSD is in unknown functional condition, but it appears to be complete. Now all I need before I can even start evaluating it, is the software package. Anyone have a copy of HP ChemStation  G1701BA Version B.01.00 ?

* A rare old cardboard slide calculator. Bell Telephone Labs 'Resonance Computer'. I collect such old cardboard slides, have a few now. The aim is to put them free online for historical interest and as working animated tools, via scanning and Javascript.

* A General Radio 900-TUA RF microwave tuner.  My second one, because it was cheap, and it's possible to need two. And shiny!

This showed up a couple of days ago. Like many of my ebay purchases, I have no idea why I bought it. It came with a board to turn it into a headphone amp, which I may or may not ever build.

What the hell? Dual valves, built using VFD construction? This exists?
Actually yes it does...
Not the first time I have seen these.
Most of the advancements made in vacuum tube design that occurred during the fifties though the seventies have gone unnoticed. Aerospace, and the nuclear arms race pushed this technology until the transistor and integrated circuit were ready for prime time. Even still vacuum tubes didn't leave aerospace entirely. (as far as I know)

Hey Sue, please don't think I'm putting valves down. I *like* vacuum electron devices. Just hadn't seen an amplifying valve done using VFD construction. I wonder if those are light sensitive at all?

Recently I got myself a vintage ESI RV622A voltage divider. Interestingly, it was apparently owned by NASA before, so I hope it does not beam me into a parallel universe when pressing the wrong button. When supplying 10 V (10.000062 V according to my DMM) and dialing in .123456 it provides an output voltage of 1.234324 V. This represents a deviation of about 0.02% - not bad for such an old device. However, I had to treat the switching contacts with a lot of  DeoxIT D5 before...

Happy New Year to everyone!

I have a RV632 from when they were still known as Electro Measurements Inc.

Apart from taking a known voltage and giving a ratio output, what would the practical or realistic uses of these be?

I have a few EDC 10v references that I can dial up what voltage I want, so would that RV632 redundant? Are they more useful for people who only have a fixed voltage and allow them to get any voltage below that point?

The RV632 has a input impeadance of either 5k or 10k ohm, so it isn’t going to be of much use with higher voltages or voltages that suffer from loading.

My Christmas presents to myself was the very cheapest CNC engraver / router I could purchase from ebay for £125.  This is a self assembly kit and I just fancied doing a quick and easy build to help fight the Christmas holiday boredom. I definitely class this machine as a toy although I am hoping with a bit of tinkering that I can get it to mill out PCBs. On that note does anyone know if FR1 or 2 copper clad board is still available as not found any on eBay etc.

The CNC I bought was called the 3018 Woodpecker CNC but they go by lots of different names etc.

I would definitely recommend buying this machine for the fun of building it and it’s low cost. It’s probably worth more than the sum of its parts etc.  I’m hoping to purchase a larger milling machine  when the sales come up later in the year and planning on doing a CNC conversion and think one of these little machines is a good learning tool etc.  I been using Fusion 360 for a little while now and look forward to trying out some of its CAM features soon.

You are certainly right that these days there are more convenient ways to generate accurate voltages, mostly I bought it because of the vintage aspect. However, I am considering to use it for occasional ADC and bridge circuit testing. It might be useful in situations when the reference voltage is unstable (e.g. drift) and all that matters are relative proportions.

Anyway, I turn this light on, and it has an emergency  blink mode. It has ONE mode - blink. I can't find any way to get it into 'just work you f*cking thing' mode. There's only one control - power on-off. Rapid power cycling via that button or the mains plug make no difference, though ONCE it came up in normal-on mode. Cannot repeat that. There is no mention in the 'manual-ha-ha' of any modes, or blinking.


Gosh... why on earth would anyone want blink mode on a work light? And undocumented? without a specific way to make it do what every user will expect to use it for? I can't see bunnings buyers would want something like this in the store either... based on what you've described, if this is the proper functioning of the unit, I'd expect that every single one they sell will end up a return.

So yeah - I'd expect  the power supply in the unit is faulty and it's oscillating..

Assuming the bunnings isn't a long haul from your place, I'd just take it back... then if the one they swap has the same problem, take that back and swap for something else which is actually fit for purpose (good old Australian Consumer Law!)

I did. So now we'll never know why it was blinking.
No, there should not be any such mode in a work light. But I suspect they may have used some LED regulator IC that was intended for torches. And somehow it had blink mode enabled. It did _once_ turn on in non-blink mode. Or, as you say, possibly a power supply fault.
Made them plug in the replacement light in the store, to check it. Didn't want to have to make another trip.

Those results seem WAY off what they should be. Squinting at the picture of your DMM7510 the reason is obvious - you are measuring using 10M\$\Omega\$ input impedance!

Try measuring again with >10G\$\Omega\$ High Z.  ;)

 Another present - one of those cheapo capacitor meters. Put ti all together, curious how they didn't use a socket for the ATMega48 micro but, oh well. Fired it up - worked perfectly. Then I see the small piece of foam, hmm, what is this from? Oh look, a socket for the micro!  |O Oh well, parts inventory just went up by one for 28 pin SPDIP sockets.

Arrived today. Power Designs Model 5005R. 20VDC up to 500mA. A quick test was very promising for eBay score, for just $23 shipped.

Finally sat down to play with this unit and unfortunately the output jumps straight from 0.4V up to about 10V and it has a few more issues. So, I will get to open it up and poke around. Also, the Keithley 2000 arrives tomorrow. Ill try to get both units into one short video clip for anyone interested.

I guess they were trying to sieze the opportunity of screen rendered text, and have a way to make web pages break away from being static, like a piece of paper... I guess they do that, and allow simple access to make it happen for the web developer.... but cripes that was tacky...

I've bought myself one of these (extremely overpriced in their time) office lamps and had a light-gasm  :-*  ;D.
Of course after I removed the years of caked dust and grime, but holly God of light, my tired old eyes said thank you so much !!!
I definitely recommend it and the seller in Frankfurt a.M seem to have more for a very acceptable price (PM if you want the Kleinanzeigen link).Mannheim is in between two rivers, and from middle of autumn to middle of spring it's Gotham City cloudy, I thought my eyes are gone bad, but really the natural light is miserable bad and the table lamp was not cutting it anymore, I'm so happy now with 4 x 55W daylight goodness.

Is it fluo or led? 4x55W is a lot of Lumen  8)
I have now 35W led office fixture dimmable 4000K over my desk which is more then enough.
I wish in the future to make it tunable white since I wake up under the light so if i sit at my desk in the late evening i notice that my sleep is gone.

It's fluo, this why they show cheap now, the office buildings are kicking them out and use the LED ones, otherwise they are crazy expensive but build to last.
The lamps can be switched on in pairs of two: 2 or 4 at a time.

Tens of years starring in a CRT reduced my retinal sensitivity :(, but if one has good eyes it's ultra simple to put instead 4 x 15W lamps, I will still stay with 4 lamps to have a better spread.
A new lamp is in between 2.50-3.50 EUR and it really feels like sunny in the shack  ^-^

I have my fingers crossed I didn't just piss away $275. Seller states just needs a cal. Pictures show its been opened but I am hoping it was just in a rack. I'll know within a few days."

It arrived! The aluminum plate on the bottom is a bent/wrapped and that is my guess as to why the tabs on the top-front of the case were sticking out. Otherwise, I am very pleasantly surprised that it passed the 'built-in self test' and I have no found any issues with it, yet. I will try to get some video for anyone interested. So far it seems I have picked a jewel out of the rough.

When I opened it up, everything looks  original and I cannot see any immediate signs of repairs or part-swaps. The PCB dates to 1994 and most of the chips are mid-late 95 with a few stamped '96. While it is still to early to say, I hope I get to shout "Winner-winner, chicken dinner".

My next project calls for a 100uA analog panel meter. So i start out looking locally at the hobby shop and well their stock is at zero and their catalog offering was small, hard to read  "One-Hung-Low Brand, so pretty much rubbish...

So i trawled for probably an hour through Ebay and found a few, almost all from China, some Korean and and some from yaiwan. I found a couple but they were small scale, oval in Bakelite, very old and more at home in someone's museum collection...

I next turned to the local sources again namely via the self styled online auction company known as Trade Me and had a search. Instantly up came a nice not too 'old-school' 80mm square AWA unit.... i guess there's an old adage... always check locally before wasting time looking for something you may not ever find!

A far as I can figure she is some kind of bantam Leghorn.

I like the switchable wheel too,  where I first had free run on all the time, I have moved away from it lately - only turn it on when I really want to navigate huge documents like microcontroller datasheets and the like, and end up turning it off pretty soon after that -  in a lot of websites it seems to be a bit uncontrollable, and the page drifts...

Have you installed the Logitech drivers for it ?
I use a Trackman corded mouse and if you want its full functionality you need install the correct drivers.

Ebay score!  Both in great condition (needed a little elbow grease), perfect working order.  $70 for both.

Unfortunately my workshop PC monitor doesn't have HDMI input so it will have to use USB for display (which reduces the real-time display resolution). It does have the little 5" built-in screen but I can't see me getting on with that for long - not with my eyesight :)

Not so much to do with the color of the plumage.  You can tell the color of the eggs the chicken will lay by the color of the earlobes.  My wife likes the colored eggs so we have Easter Eggers, Ameraucanas, Marans and others.  I like the crazy hair so we also have Silver Laced Polish (named Beaker after the Muppets Show), Silkie Bantam, Gold Laced Wyandotte, Plymouth Rock and a  Frizzle (named Fajita).

Out of 17 birds, we only have two nesting boxes, they all tend to lay in the same box.  Sometimes a girl will get broody and want to lay on the eggs, then we have to put her in chicken jail for a few days to break her.

Well I bought a bottle of red wine and that’s how it started and not for the first time. I always fancied having a delta style 3D printer but don’t like the look of those nasty long rubber drive belts. So decided to go down the ball screw route and  yes and I do know about the problems accelerating ball screws but I’m going to be bloody minded and have ago anyway. So have three 750mm long ball screws and three big nema 23 stepper motors and 4 amp drivers boards on the way from eBay.  It will probably shake itself apart but it is going to be a giggle anyway and I fancy doing some construction this year.   I have gone into this project blind without any real research or understanding but that’s  half the fun.  I will keep you posted regarding impending failure.

That "CAL" button is not so... it is simply a plastic blob covering a hole in the front panel. Is it possible to calibrate the temperature in this thing?
Not a single word of calibration in the included "chingris" leaflet.

Remove the "plastic blob" and stick a small screwdriver through the hole. Tweak the trimmer potentiometer until the displayed temperature is correct.

Before you start tweaking you have to decide at what distance from the nozzle the temperature should be measured.
Depending on what distance the manufacturer used, and the distance you use, the display can be correct or way off.

You should open it and verify that the mains cord is actually attached correctly, since that seems to have been an issue on some variants of these things. (At least yours doesn’t have the fun suicide connector like mine! :P)

The images look a bit blurry, like if it was scaled from a lower resolution, and the white colored areas are bleeding. But still good for the price. With the motor you could do focus stacking with it.

The bleeding is from lens effect, and the camera doesn't have built in lens correction, not even dead pixel mapping. It basically captures data straight from sensor, doing minimal white balance processing and zooming and dumps it to HDMI.

The lens set is also crap, what do you expect from a lens set came for free from a $350 microscope?

It can't be controlled by computer, it has a USB port for a mouse, and that's how I can control it. Scripted focus stepping is not possible, but if I really want, I can manually step them and save each frame to TF card, it has a TF slot.

I think, I would go for one of these:

3x ATTinyy85
5x 3.3V regulators
5x 20MHz xtals

I always wonder if people packing the orders assume these things are going together and smile to themselves thinking the orderer has made a mistake.

In fact the xtals and tiny's are to go together but the 3.3 regs are for powering ESP8266s.

These are my reasons:

- most likely I'd buy the one with 1x - 70x magnifying because of the working distance:
            (quote from TSP) AM73115MTF – USB 3.0 with Dino-Lite’s longest working distance
            at 1X – 70X magnification. Capable of 20X at 10.5” working distance and 70X at 4.5” working distance.

- you can inspect "hidden" places, which cannot be seen directly
- easy change of viewing angle
- easy to transport (I am in the repair team of a so-called "Repair Bar", which is 40km far away from my home.)

I think farnell, rs, cpc have partially automated order systems.  It looks like some of the parts, jelly bean stuff off reels, have been individually bagged and labelled using pick and pack machines.  They also charge reeling fees for bulk orders that don't amount to a full reel etc.

Actually my last RS order they started using paper bags for some of the components, obviously inline with the current anti-plastic waste initiative.  But then in the same order where I ordered 10 5V regulators, they came (TO-20) individually in 10 anti-static bags.

That said I got an order from CPC where everything looked like it was pick&packed in individual pink antistatic bags, but there were handwritten order numbers on each individual one!

It's probably cheaper to buy antistatic bags in bulk than to stock two kinds of bag for each size. It also eliminates the possibility of a packer accidentally using a non-ESD bag for an ESD-sensitive product. It’s not as though antistatic bags are particularly expensive.

Some of them use the pink antistatic tube, the component goes in, an iron seals and terminates the tube ready for the next component.  Neat idea.

LOL Yes, I have yet to receive an empty one, but I can see that happening. 

On packaging fails.... I got 10 8 pin DIL sockets and 10 28 pin DIL sockets from RS.  The 28 pin ones where neatly pushed into foam, 5 a side.  The 8 pin ones where stuffed into a bit of bubble wrap which exploded on opening sending DIL sockets all over the place, took me about 5 minutes to track them all down!

The Keithley 2000 arrived from 'express_auctions' and after a quick once over under the hood, I powered it up, and found out a bought a great parts unit. :palm:

Fails all built-in self tests and is, more than likely, beyond economical repair but I might try anyway. If I get to play with it, I will be back with loads of "help me please" questions...

I am not knocking the company, who posted clear pics and listed it as "not working," I just wish they'd give us the entire story. (The BIT:Auto takes 30 secs and gives potential buyers loads of useful info).

A right mish mash today.

{
   * 3x 3.3V regulators L87L03's I think.
   * 5x ATTiny85's
   * 5x 20Mhz xtals
} ATTiny85 stock pile

{
  * 10x Shoctky diodes that look like they drank the "Enlarge" bottle
  * 1x100uH inductor
  * 2x LM2576-T
} Buck converter stuff.

* 1x Bidirection 5V/3.3V multi channel logic level converter.

and... finally.

1x I have absolutely no idea.  It's most like a sensor board of some kind, looks like humidity air pressure or temperature, but I'll have to read my ebay history to find out.

EDIT:  BMP280 Air pressure sensor.  Which is a bit tough as the one that showed up a month ago (ordered at the same time) does pressure, humidity, temperature and is already in operation.

Personally, I'd be inclined to raise a claim, granted its not working, but they failed to tell you that it failed the start up diagnostic test, you could of been under the impression that it had a broken power supply or similar. You might get to keep it and get a full refund if you go through Ebay.

You are right, you probably could get that out of Ebay.  Which seems somewhat shady to me.  Trying to get something for nothing is wrong whichever side of the transaction you are on.   You are assuming that the selling party had the device open and looked under the main board as you did.  May or may not be true.  My personal experience is that ignorance and incompetence are far more common than malfeasance.

Another approach would be to go to the seller directly.  Who might refund the price upon return shipment, or possibly even pay for the return.  Or what might be the fairest resolution - return of the purchase price upon proof of destruction of the merchandise.

Most sellers value their reputation on Ebay and many will go beyond their stated policies to avoid negative ratings.

Is this the one that you got? https://www.ebay.com/itm/Keithley-2000-Multimeter-6-5-Digits-For-Parts-Or-Repair-/302345829802? (https://www.ebay.com/itm/Keithley-2000-Multimeter-6-5-Digits-For-Parts-Or-Repair-/302345829802?)

If yes, then you may or may not have a case as they went to great lengths to provide plenty of clear photos and to be honest I don't think that I'd have gone for it unless I already had one that I was looking for parts for and even then it would have to a real bargain price.

Having said all of that however, you say that it reports a fail on self test which it does automatically on power up is that correct? If so, can you get it to go past the fail screen because they clearly show it reading mVAC in which case you may have some merit in claiming.

If you press a claim it might be wise to do so with the seller direct first and then go to Ebay if they refuse to assist you, but I think it would all depend on if this is the one in the listing and if you can get out of the power up display?

Looks to me like it failed the first time because it did not see the 4 wire test correctly, but the second time when you put the adaptor in and then connected with the probes it did see it and did so on the next time you repeated that sequence.

I did however notice that the 1st time you measured your line volts it read 124v and the second time it read 125v. I also notice that the display is extremely faded, more noticeable when you first power it up though so thats going to be an issue in the future.

Just to be clear, I am not complaining about the unit, I expected a non working meter. I was surprised to find that it had been tested and the results were “intentionally” left out. The seller replied immediately and offered me a full refund. The very well written reply stated they do occasionally test units and post all the results, but for some reason, this one didn’t get processed correctly. Given their quick and detailed reply, I’ll do business with them again...especially if this unit works, as I still need a parts meter  :-DD

Having spent the best years of my life in the military, I believe deeply in honor and integrity and live my life based on those values. I would never attempt to get cash from eBay and have them eat the loss...that’s shameful behavior.

About the video: I noticed the same things about the line voltage and other oddities after rewatching the video...maybe I’ll get lucky, but should have fun trying. I’ll get the other 2000 back on the bench and see what I can find

If I recall correctly, Express has experienced techs who fix test equipment. They have at least two eBay accounts: Express Test and Express Auctions. The former is for the good stuff (tested, repaired, etc.) and the latter is for everything else (untested, couldn't fix, BER, etc.).

If I didn't recall correctly, corrections are much appreciated.

Just also to make it clear, given the evidence of the video and also my comments a couple of posts ago, then I really don't think you have any basis for a claim anyway. I was labouring in the first instance under the impression that the self test was the first thing that it did automatically upon switch on like so many meters do. I have a Phillips meter which does a self test first, but the Keithly clearly does not, so their photograph is not in anyway misleading. If anything, they have gone above and beyond to try and photograph all the problems that they could detect to ensure that they are being fair with the buyer.

Are sure that it is their tag? I can't see anything that suggests that to be the case, it might be that the meter was sent for repair to an repair agent and they reported that it was BER so the original owner just left it for scrap and then it wound up being put up sale on ebay?
Title: Re: What did you buy today? Post your latest purchase!

Nope, I'm not sure, which is why I said that I assumed it was based on tags I've seen before in their listings. Totally circumstantial and potentially errant. ^-^

$175 seems a lot for that scruffy meter especially as it isn't working or even complete. I bought a tired but working Keithley 2000 meter a few weeks ago for a small fraction of that price at an auction. I wanted the handle and feet off it for my K2015 and it seemed like a worthwhile gamble if it meant I got a working K2000 as well. I think the handle/feet kit is/was about £40 delivered from Keithley and I didn't pay much more than that for the K2000 with the handle/feet. But the meter is yellowed and grimy and the display is quite dim on it. But it does seem to work fine. The handle/feet seem unmarked on it so I think these were fitted to the K2000 fairly recently. But they are now on my K2015 and it really does make the meter nicer to move around and use.

I'm not sure what I'll do with it in the long term but I have been using it as a logger via GPIB quite a bit. So I'm probably going to keep it as a spare. It really does need a new display, in the images below the display looks OK but it's a bit dimmer than this in daylight. I just gave it a quick clean for the images below and ran some T Cut over the casing. It had a user name crudely painted on the top cover with a large paintbrush and this fortunately came off easily with the T Cut. All the front buttons had a halo of dirt around them from years of dirty fingers. I'm guessing the person who painted their name on it didn't wash their hands much. it actually looks quite good now and some of the yellow has gone from the bezel since I cleaned it.

Inside it looks brand new with not a spec of dust inside. I checked it for leaky caps on the day I got it home. It looks quite good now but has a few cosmetic issues. It is only a year out of an expensive UKAS calibration and seems to work OK. It's within a couple of LSDs of my K2015 on the voltage ranges but that was just a quick casual check across a few voltages. However this thing is old, it is probably 20 years old. It's also a lot lighter than my K2015 when I pick it up. This was a nice surprise as I don't like the heavy feel of the K2015.

Looking closely, it's still a bit grimy in the image below if you look at some of the buttons as they still have a faint film of dirt on them. But they were absolutely filthy before I cleaned it and it was hard to even read the button logos.

That display pretty normal to me, I've certainly seen far worse and I'd be happy with a display like that on my bench. Even LED's are hard to read in daylight if there's a hint of sunlight hitting my bench, its almost goodbye LED's, then the only displays I can ready quickly and easily are the LCD's.

The meter looks pretty clean and presentable as well, good job done with clean by the sounds of it.

There are a few threads here with info on cosmetically restoring 2000/2001 meters.
You can disassemble the front panel rather easily. The rubber keypad can be simply washed in soap and water. You can also safely use IPA, I've never damaged the lettering.
The yellowing can be reversed using a technique popularized by guys restoring old computer and game consoles. Google "diy retrobright". All you need is strong hair peroxide (I use a "30 Vol" gel type from a salon supply store) and sunlight. With the right type of peroxide, it can be finished in less than 30 minutes.  Be very careful of the silkscreening on the transparent lens of the display, it is easily damaged. The peroxide/moisture will soften it and it can then rub off easily (until clean and dry again). On most of my Keithleys I found it was easy to remove the lens from the frame to avoid any issue due to the de-yellowing process.
You will also find info in these forums about rejuvenating VFD displays. One technique involves running the filament "hot" briefly to try to remove surface crud which otherwise reduces electron emission. Another involves simply increasing the filament operating current slightly for more emission. Both techniques have some success stories.

@macboy, I would have loved to have this info last night. I ended up using the 'brute force method' and wet sanding the surface. Of course this removed the menu options so I'll have to print new labels after refinishing the front bezel, making this a resto-mod. Thank you for the post and I will check the other threads for future restorations.

All yellow.  :palm:
In the case of Wiha, the yellow signifies ESD compliant (non-ESD versions = red caps). For disclosure, most of my screwdrivers are Wiha.

Personally, I think they should have at least printed a driver type symbol on the cap. Other brands do this, so it can't be that hard or expensive to do so.  :-//

I second that.
I have spent thousands on Wiha over the years. Almost all of my screwdrivers are Wiha.
The lack of identification on the top cap is my only complaint.

Yellow fits all  :)

I have the system 4 esd set and they have coloured coded bits which is only interesting for pozidriv vs phillips.

FWIW, I've the System 4 ESD Drive-Loc kit (I love the ability to set the blade depth  >:D). I also own a System 6 Drive-Loc kit I assembled (predominantly security bits). Aside from the larger bits, the handle I have is a non-ESD compliant version (again, red instead of yellow like the ).

Both of these also use color coded blade tips (downside is the enamel wears off rather quickly IME). It's very handy for Pozidrive v. Philips, as well as narrowing down hex sizes (i.e. SAE v. Metric).

In the end though, I find it's still more trial and error to get the right size.

That is pretty much the only thing that goes bad on these great LaserJets.
They just last forever.

Where did you buy the roller kit?
Was it original HP?

Good choice IMHO.  :-+

Brother laser printers are cheaper to operate IME (I've an MFC-9450CDN), and I've never seen any of their cartridges chipped. ;D So easily refilled, further decreasing operating costs (reset the gear position & install a new plug after filling it).

That is the way things are going. I got a $90 Brother WiFi laser printer about 6 years ago and have since spend $20 on toner recharges for the original cartridge. Nothing else. I have probably done 8000 pages. When the drum dies, I will just get a new printer.

Yep.  The ink, where they make their money is more expensive than a new printer.  But the toner cartridge shipped with the machine is small to get you back to the store soon.  I bought a cheap Brother laser printer for about CDN$80 with the intention of using it ONLY for the purpose of making home-brew pcbs.  At the rate I do boards (1-3 / year) I calculate that the starter cartridge will last me the rest of my life.  5 years on and so far so good.

Bought a DPS5015 with USB/Bluetooth, info provided is not great so it's not obvious how the BT device connects and I assume you have to choose between USB and BT? - there being only one connector (that being said, there is no separate cable for the BT PCB and the USB one doesn't look like it fits). No driver/software either.

Also recieved the new Brother laser printer, entirely unexpected as it was due to be delivered on Thursday. Very lucky I was actually in the house to answer the door today. Anyway, something else to play with :)

I also have 2 Canon photo inkjets and a Brother all-in-one inkjet (plus heaven knows how many other unused inkjets stored in various cupboards!). I'm off-loading the bulk of the kids schoolwork printing needs onto this laser, it might be cheaper to feed (certainly quicker). Just got to train them NOT to hit print half a dozen times just because the printer doesn't respond instantly...  :rant:

Received the Kyocera P3050dn laser printer I ordered Jan. 10th 2018 (Wednesday last week) in the evening.
I chose and paid for "Premiumversand" -guaranteed delivery (most likely the next day after shipping)..

Next sign of life: Thursday, 11.01.18 16:19: shipping label registered at DHL.
Friday: Waiting, nothing happens.
Saturday: Waiting. nothing.. -no, wait: Saturday, 13.01.18 10:40: Package registered at DHL the first time.  :wtf:
Skipping Sunday; Monday (today):  Monday, 15.01.18 11:59 Package finally delivered.

Great! Only slightly late. (*irony*)

Unboxing, installing according to manual, first print.
Printer is producing a smeared printout.  :palm:
Going through every step of the manual to get a sharp, smooth printout: Shaking up the toner, different Cleaning steps. Nothing helps. Calling the Kyocera customer support, result: printer is actually DOD (defective on delivery). :palm:

Ok, getting back to amazon, got a return address label.
Monday, 15.01.2018, 19:06: Printer shipped back to amazon. Replacement will be delivered. When? Nobody knows but amazon.  :palm:

This day was completely useless. Spent seven hours of my flextime wage record for nothing.  :rant:

Sometimes you loose, sometimes the others win..   :-DD

For me, the other printer is an Epson Workforce all in one.  I have a company provided HP color laser and a UPS thermal printer for company use.  The Brother responds much more quickly than the old one but the 1440 wasn't a network printer.  That was connected by an HP JetDirect EX Plus print server.  It also prints almost twice as fast so that is awesome.  I keep telling myself that I don't want desktop lasers because they are such a bear to work on but the price I paid put it on par with an HP Laserjet 4000TN I was looking at with adding on a duplexer and the HL-1440 has been absolutely reliable-not even a paper jam.  My wants were 1200 x 1200 dpi and a duplexer.  I get that with the Epson but it will be cheaper to feed the Brother as I don't often need to print in color.

Gonna do some tiny part CNC, particularly copper alloy and aluminum alloy.

Spindle is rated at 50W 10,000rpm, so as long as you are doing engraving or micro machining with 1/8" bit or smaller it should be OK.
Get extra bits and delrin or similar to practice on.

Testing the DPS5015 with USB coms module. I guess the basic thing works but I find if I get much over 55w output the controler resets and the USB connection is dropped (not sure which happens first, whether the dropped connection resets the controler or simply the controler resets and thus the USB connection is gone..). With a 30v/3A input it should be good for 90w or so, can't get near that without it dropping out. Need to do more testing to figure out what is going on. Output voltages seem to be accurate though, I ask for 5V and that's what I get :)

Edit: It may be seeing the two power resistors (effectively 0.5 Ohm) as a dead short which I guess could be upsetting it...

Saw this locally, snag it cause its damn cheap about $10  :palm:, and was not expecting too much from this price level. But after played with it for about 30 mins, actually its quite decent. And also as the twistable 2 shapes (gun vs straight) is pretty handy too.

Next is to tear it down as according to manual it uses 3 NiCd cells (3.6 V) inside, wonder if can be modded to fit in a high current discharge 18650 Li-Ion cell with cell protector & charger, as the handle volume is more than enough to fit it in.

Followed the 4 year old video and in 10-12 minutes including desoldering the old lens in my 44 degree shack. Quick check with some shaky hand held snaps on low res and all looks great  :-+

Working distance seems around the 150mm range and maybe 20x25mm or a bit larger area.

Thanks, but that is exactly what I need. I had a strong suspicion the photograph was wrong all along, as the Rigol cal procedure calls for the multi-cable setup and not for a board - which you are right: the DS6000-DK is the demo board (which I don't need).

I sent a PM to the resident TEquipment account around here to let them know about the problem. Hopefully they read private messages.

I finally received my stackable silicone banana leads. Against my better judgement I ordered them from far away lands. They seem okay. The resistance is very low, which indicates they didn't skimp too much on the materials. They are a bit tighter than I'd like them to be, but using them a few times helps. One plug crapped out almost right away, so the judge is out on the quality. Might have been a dud, or the durability isn't that great.

I'm yet to have a go at them with the soldering iron to see how the silicone holds up.

Yesterday I got some LM2576T-5 G's from RS Components.  The order was for LM2576T-5 G, the stock number was for LM2576T-5 G, the antistatic bag the parts where in said LM2576T-5 G, but the components where small surface mount 3 pin devices that look like linear regulators and most definately not TO-220-5 devices.

Obviously I will return them, but as the anti-static bag has the correct stock number and part name, I'm worried I will just receive the same wrong part back again.

I've also now found that 2 of my 5 ATTiny85s from RS are DOA and might need HV fusing... or are totally dead.  Not really worth returning at £1 each though.

Well, the two LM2576's I got from a British seller, which are probably from China and not much cheaper behave awfully like linear regualtors.  Voltage drops from 5V to 4.45V when you pull 0.5amps through them.  When RS hopefully sort the order out I intend to straight swap the component and see what happens.

I hit the mother lode at the thrift store today. Nearly 20 NES, SNES and Atari games for roughly $25. Some are in rough shape, but having daily drivers is more fun than prestine collector's items.

I'm debating going back for the Atari 2600 and two more games. Not as cheap as the rest, but it'd be a neat console to add to the collection, even though it's not part of my childhood like the rest. No TV connector or power, though.

That is marginal even for the ultra-low cost.

For reference - I got 4" vises recently, they were over $1,000 USD each. Very good quality.
The ripoff version from China is about $250 through US distribution. Quality is marginal.

Is everything CNC related all THIS expensive?

Good quality stuff is. Brands like Sandvik Coromant or Seco make the best tools. And when you see the work it takes to make end-mills for example, from steel manufacture to thermal hardening, you'll realize that it is not that expensive.

This is a nice catalogue of everything cnc related, although you'll only need the smallish stuff for your cnc, they are well known in Europe not sure if they deliver in the US.

I've had many machine vices and I would suggest buying one with the moveable jaw on a (adjustable) dovetail slide. The blue one pictured is a 6" jaw width vice made by Bison. The smaller 4" is a no-name vice that always suffered from jaw 'lift' - you tighten it up and the moveable jaw lifts a few thou (that is what you want to avoid).

The type of vice to avoid is anything that looks like the green one on the second image - horrible thing that wouldn't grip anything. Looked OK and was well made, but the design is just poo.

The meter came with a padded soft case,thermocouple and test leads that look like the ones Dave supplies with his BM235.
I have no idea if this is the norm when you buy a BM896S.
The actual supplier was Welectron in Germany.
I get the impression that Welectron are a pretty good supplier.

Well, asides looking at the paypal notifications on the phone this morning and groaning, it didn't go that badly.

I bought a DPH5005 boost/buck PSU and case for £50.  It started when I decided I could run my bench on solar power, but my only DC input PSU is a buck coverter and won't produce 12V from a 12V input.  The beer got to thinking and... we'll see what it's like and how much smoke it releases in a few weeks.

I bought the DPS5015 with comms, then realised I need a higher rated input for it so bought one of these: http://www.ebay.co.uk/itm/192325585960 (http://www.ebay.co.uk/itm/192325585960)  -but there's no way it's going to supply 800w for longer than a millisecond before it turns to glowing slag...

Video the load test.

My take on this is a bit "belt and braces".  I don't need a 50V power supply.  I might need 24V tops.  But if I buy a cheap 24V power supply I might need to run it at 100% rating and be disappointed when it doesn't meet it's specs or go kapoof in a white cloud trying. 

So I buy a larger supply than I need, so it runs gently.

I have the DPS5020.  I have not attempted to pull 1000W through it and nor do I intend to, EVER.  I have pulled 20A through it for a few minutes, but got a bit scared and backed it off.  Scared for the PSU and the LiPo it was charging.  4C charge is a bit too dodgy for me, though a lot of people do it in the field.

I went for a 48V 10A LED lighting brick for the DPS.  If you can live with lower voltage LCD Monitors and TVs are now going "external" DC bricks with some impressive ratings.  My monitor has a 24V 8A brick for example.  Gotta be some on the second hand market already.

I got this rather lovely microscope delivered this morning. I'd been looking at getting another to replace my first foray into microscope which was an Andonstar A1 which was reasonable but suffered from too much free play and a breeze would blow of focal point, so I started to think about the Andonstar V160 which featured a more robust design of up stand pillar to help remove the free play.

No, I got mine from AliExpress, it will take stills VGA, 2M and 5M but the 5M on the microscope itself takes an absolute age to process and save but that might be a function of the SD card, I'll have get a class 10 and try it. You can also plug it into the computer and with some suitable software via the live image on the monitor. The software (not supplied) will take snapshots, the following are taken on the computer with the lens about 9cm away from the PCB.

Tomorrow I'll take some snaps on the SD card and compare /post them here.

It's an RCA Model 143, introduced in 1934.  The cabinet is a bit rough (understatement of the year there..), and it will need to be recapped, but I think it's a pretty cool looking Art Deco-ish piece, and has some nice potential.  All I need to do is learn to veneer, and fabricate the missing cabinet trim bits.   :-DD

Lab Cat, of course, was keen to get going on it immediately.

No, not impressive for that price.

I have to say, I was impressed with my recent purchase of this 2 1/2 " precision toolmakers vise. They can be had for $60 on eBay.  Appears to be good quality tool grade steel and square. Smooth with no significant slop or backlash.   Not high end for sure but for the money  :-+

I bought a new project for my 'spare' time from the antique radio museum where I volunteer.

Pat, that radio is beautiful as is, can't wait to see it nice and fixed up.

Yeah, I thought it was pretty cool looking, so I made a donation and it followed me home.  Have no fear though - its place in line is somewhere BEHIND the long suffering HP 5340A.   ;)

Now for some shots taken from the microscope screen direct to SD card in 2M size.

Pretty impressive piece of kit, its weakness is the lighting, needs a ring light to take advantage of its abilities with out suffering from reflected light entering the lens and spoiling the image.

Anyone know of a ring LED light that will fit onto a 33mm dia barrel?

Produces clear images, and I think you're right about the lighting being an issue - more because of reflections than anything else. I've already decided to add a polarising filter to the end of mine, I've got a 38mm dia one lying around somewhere to try. With that fitted it should be possible to knock down the worst of the blown highlights which are inevitable with a bright light source and shiny pins etc.

Awww..  Those baby vise grips are sooo cute!  If you feed them, will the get bigger?   :-*

Seriously, I don't think I've EVER seen them that small!  Very cool.

I've bought them at Hornbach (building centre in Germany https://www.hornbach.de/ (https://www.hornbach.de/) ) for EUR 2,50 each incl. VAT
This is the vice grip: https://www.hornbach.de/shop/Mini-Gripzange-110-mm/8397016/artikel.html (https://www.hornbach.de/shop/Mini-Gripzange-110-mm/8397016/artikel.html) and the quality
convinced me nearly immediatly (heavy and solid construction) so I bought three of them.

Another eBay gamble. This time from "jollyg00d" (i believe those are zero's not O's). Seller was super friendly and gave me what I think was a great deal. Powers up and looks promising.

I doubt that Fluke 335A is that much of a gamble. I think you have already won with that 7 digit Fluke resistive divider.

Even if it has been damaged, the important bits will probably be fine.

20 ppm absolute accuracy and 2ppm/C maximum temperature coefficient - it is just stunning what Fluke was able to do in the 1960's.

Specmaster,"Anyone know of a ring LED light that will fit onto a 33mm dia barrel?"

I have an entire bin of miscellaneous medium and small LED's and will try to find a couple suitable parts for you tomorrow. Not sure Ill have a 33mm ring, but I know I have some small strip lights that use double-sided -3M tape. I think they are 65x25x5mm and would stick to the frame on each side of the light. Each strip holds 3- 5.5mm LED's and use 12VDC.

(How do I get this stuff: There is an Amazon return "rummage" store in town and I visit it once every couple weeks and grab all the high power LEDs and various projects. I am amazed at what I find there. Anyway, an entire basket of goodies is $5, so if I find anything that will work for you, you may have it).

I couldn't resist. The first time I saw the Tagarno Dave was using, I wanted one. And today I got one, a FHD Trend (https://www.tagarno.com/digital-microscope-tagarno/tagarno-fhd-trend). Live view on a TFT display, and at the same time streaming over an USB3 connection to my Linux system, works without problems, maybe just sometimes it freezes for a short time over USB, but not on the TFT. Need a better computer now, or experimenting with other recording software or settings. First test recording with VLC:

Post by: FrankBuss on January 22, 2018, 01:29:32 pm
I ordered it with the standard +4 lens. The FHD Trend was EUR 4032 and the control box again EUR 614. Worth the money for the microscope, it is very stable, heavy metal construction, and you don't get the 24 cm working distance between the camera and the surface with cheap microscopes and with this quality. Dave would say it oozes quality.

Not sure about the control box. Sure, it looks and feels nice, but I think it is overpriced for just a few knobs. But the design in combination with the software is well thought out, it is easy to use, selecting presets, zooming etc., fun to use. Well, I guess if you want a Mercedes, you have to pay for a Mercedes.

Ok a bit (3x) over my budget I must say. I did in the past buy a stereo Leica microscope for electronics that was around EUR2500 which for a Leica I think is pretty good. That this apparatus is more expensive surprises me. Then when I wanted another start zoom option (5x was too much) and had to buy two small lenses and had to pay EUR 500 for those two lenses I also had a bit of uhhhhhhhhhh. I guess the same with your control box, but in the end it all comes down to the user experience and I have no doubt that you will enjoy it very much.  :-+

I have one of theirs as well, its only a novelty really but it does work as long as your working on audio equipment its fine, and allows you to trace a signal through without quickly and easily, just don't expect too much from it mine has a very noisy floor.

I don't have high expectations of it.  At the moment I'm not probing anything, as probing involves:

going upstairs, getting the laptop, unplugging it, bring it down to the lab, clearing bench space, plugging it in, wiring up the Owon DSO

So typically the chain of events is:

"I should probe that....  Ach sod that."

Those earlier images were just frame grabs off the video, a photo is actually 12MP and more detailed. You can compare the two below (The photo is second image, although I had to reduce it to 30% of original size to post so perhaps not a fair comparison).

Maybe not as sharp but it would be tough for me to justify paying more! £220 for the lot in my case :)

Plenty of room to work underneath the camera as you can see..

I have yet to try the HDMI connection on the desk PC, it would be worthwhile to use it if only because of the increased resolution available via HDMI but sadly my workshop PC monitor doesn't have an HDMI input. I've got a [standard] HDMI > DVI adapter cable but of course the Adonstar uses mini HDMI connector :(

Also, I tried a normal polariser and also circular polariser filter - made no difference at all. That came as a surprise TBH, I would have expected some of the reflections to be reduced? Of course I tried rotating the filters whilst watching!

That's impressive, a massive improvement on my Andonstar scope, it could only manage at best 3.5", but my new one can do 6" which is enough to get and solder with ease once I've mastered the art of soldering etc while looking at the monitor. Yours has a far greater field of view I post a of picture of mine at 6" working height which is still a giant leap forwards for me, not a match for yours though but then it did only cost me £46 so I can't complain, it will be a great aid to me when working with SMD stuff. Strange though, still photos seem to loose the aspect ratio, on screen as a live feed its perfect.

How about latency via built-in screen? If it's reasonable for soldering, the lack of stereo vision might be OK, especially considering the price.

I would like to know that also.
I am just about to pull the trigger on a model ADSM301.
Web says 30fps @ 600lux.
Appears to be nearly the same spec as the 302, except:
Fixed LCD angle.
Smaller working distance.
30mm shorter base.
~USD96 cheaper.

Latency is very usable either way - you're getting 30fps which is not going to win prizes (fast movement will cause tearing) but for normal work it's fine. I just had to repair daughter's fine gold chain so I used this microscope, worked perfectly for this fiddly job.

Ah. Just realised I can get even lower magnification/wider field by moving the camera upwards in its bracket, that gives me about 9" clearance under the lens.
That's impressive, a massive improvement on my Andonstar scope, it could only manage at best 3.5", but my new one can do 6" which is enough to get and solder with ease once I've mastered the art of soldering etc while looking at the monitor. Yours has a far greater field of view I post a of picture of mine at 6" working height which is still a giant leap forwards for me, not a match for yours though but then it did only cost me £46 so I can't complain, it will be a great aid to me when working with SMD stuff. Strange though, still photos seem to loose the aspect ratio, on screen as a live feed its perfect.


I was going to buy the same model as yours, last minute decision after watching a YouTube vid made me change my mind :) Your's will certainly do the job though. Software for mine needs a lot of work - it's version 1.0 :)  You can easily change aspect ratio of saved images but maybe there's a setting somewhere (ini file?) you can change.

I can't change the aspect ration, I'm afraid thats something that I think I'm stuck with as the device didn't come with any software, its all programmed into the unit. If you use on its own monitor and press the snapshot button, you can see the distortion on playback. If I run the microscope on the PC using the software that came with my Andonstar A1 and use the Ctrl L button sequence the aspect is correct, here is a couple of shots of the same PCB one using the Andonstar software (small untouched photo) and using the microscope as a standalone item and saved to SD card, large photo also untouched. If only the PC captured image was as large the one saved to SD card but I suspect has everything to do with the fact that the A1 microscope only has 2MP image file while the new microscope is supposed to be 3.6MP.

Latency is very usable either way - you're getting 30fps which is not going to win prizes (fast movement will cause tearing)

Frame rate has nothing to do with tearing.  Tearing is caused by not redrawing the framebuffer in sync with the v-sync pulse and/or not using double buffering and attempting to draw the active frame direct while it's being output.

I use my Tagarno for soldering, too. It is so much less hurting my back to look at the monitor than leaned over my old stereo microscope. Was a bit unusual at first to look at the monitor, but now I can do it faster than with my old microscope, just soldered another prototype of my Bloxorz cartridge. I guess 60 Hz, no visible lag and no tearing helps.

What lens would you use for that then to say achieve a magnification factor of 400X and also the tripod or camera mount would be getting in the way surely?

I used to have a wooden frame over the table (ideally, you'd mount it on the wall, on something like a wall TV mount to avoid any vibrations), about 1m above, a 55-200mm lens and macro extension rings.

Only thing I was lacking was decent lighting, LED's were still pretty expensive at the time and incandescent was too how for dissecting flowers.

If I can get my hands on the macro rings, I'll sit some footage tomorrow and post it.

Edit: I didn't get 400x magnification with that lens mounted that high but that's only a matter of distance and focal length.

Edit, again: one good trick to get good magnification is to mount a lens backwards.

I've got three Canon DSLR's and I don't think you could mount a lens backwards because of the Canons mounting system and besides you need the connections between the lens elements for the focusing motor etc for the camera to function?

Reverse Mounting is quite common for macro photography on a budget, so yes, it can be done.

Mostly people use older lenses with the manual aperture ring and you need a adapter from your camera mount to whatever mm your filter thread is, then you use the camera in manual mode.

I see, thats a interesting article as well, however, I still would not dream of using a DSLR in such a fashion. the whole point of a microscope is that you can adjust them with ease to suit the job in hand and might mean that one minute it is showing a good depth of view the next you want to zoom real close to inspect something that maybe suspect or really small on a PCB so it needs to be easy to adjust.

So you need:

Reversing rings
Macro rings
Some sort of homemade wall mounting.... etc, etc...
And then spend most of your time fiddling with settings every time you change the situation?

And that's somehow a better solution than buying a purpose built microscope??

Had to buy a replacement video card for my main desktop PC today as it had died - very gracefully, the display simply faded off like a normal power save mode then wouldn't come on again. I spent the next hour trying to figure out what was wrong, rebooting, plugging and unplugging stuff, eventually I logged in remotely from another PC and confirmed it's running fine otherwise but just no display. Device manager still thinks it has a functioning Nvidia 580 (otherwise it wouldn't have booted) but both monitors it feeds show nothing. Very strange. Anyway, a new 1060 will be delivered tomorrow as a replacement and then I can look at the old card. Clueless as to where the problem might be..

Most video cards have multiple output modes, and often multiple outputs, did you try the others?

For example, mine can output to an HDMI monitor if I use a Mini Display Port adapter.

I think the card has mini-HDMI (or whatever, didn't look too closely) output in addition to the two DVI sockets, but I don't have a suitable HDMI cable anyway. There was no drama when it stopped working - no pops, bangs or magic smoke released. Whatever has gone wrong is affecting both DVI outputs. It has been running 24/7/365 for about 3 years though - apart from down times for servicing of course.

I just received this (fake) Hakko FG-100 soldering iron tip thermometer. It arrived in just 11 days which is amazingly fast compared to other purchases I've made in ebay so far.

I've opened it up as per Dave's famous motto and it's the typical fake circuit without the trimmers or jumper to switch fom ºC to ºF (this one is in ºC). The make quality is not top notch, a bit on the cheap side but not that bad whatsoever. In the back of the PCB there are some unpopulated marks for a couple of thru-hole lytics, paralelling C3 & C7 SMD capacitors and a trimmer (VR1 - 1K).

The sensors blister clearly states: "contents 10pcs." but only includes 5  :)  To be fair, the original ebay ad (https://www.ebay.com/itm/0-700-Hakko-FG-100-Soldering-Iron-Tip-Thermometer-Tester-5pc-Temperature-Sensor/111306749619?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649) clearly indicated 5 sensors, not 10.

It seems to work well although I have not a means to compare the temperature reading (yet... awaiting  ::)) . Goes up to 400ºC with my old trusty JBC iron.

Have you noticed how hard it is to judge the scale of things from pictures and youtube videos?

I remember being surprised when I got my first 18650 cells at just how much bigger than AA's they actually were, but I'd seen dozens of youtube videos of people handling them.

Tuesday night I got a surprise when I opened the DSO112A scope.  It's absolutely TINY!  I'd watched several reviews of people handling them, but it never looked just that small.  It will literally it in the palm of my hand with virtually no overlap.

Will do, it states that the inside diameter is 60mm and with those long screws it might just clamp onto the barrel of mine which is 34mm, failing that I should be able to source some longer screws, at least thats the plan. 8)

This arrived today, although I already have a few ways to measure everything that this using more expensive equipment, I still like these cheap Chinese testers for quick tests they are actually more accurate then a lot of people give them credit for.

Here is the actual value using far more accurate meter but as you will see its not that bad.

So all things considered I don't think there are that bad after all?

What is the "Vloss" reding for capacitors?
Vloss is the percentage of volts that has been lost in the capacitor since the tester first charged it. A low value % is good as even a new one will have have lost some voltage as nothing is ever 100% perfect. As electrolytic's age, they dry out and the amount of drying out can be seen by the Vloss figure, the higher the value, the nearer a capacitor is to expiring so therefore it is wise to replace a capacitor that has significant Vloss and it is also very likely to have a high ESR reading as well.

But that should depend on the capacitance, right?
Yes it does, ESR also depends on the capacitance value as well and both will be affected by the capacitor drying out as it ages and or is exposed to high levels of heat for extended periods.

Yesterday I ordered a couple pairs of 1m 14AWG silicone stackable banana leads (https://www.ebay.com/itm/172002582714 (https://www.ebay.com/itm/172002582714)) and this morning I ordered an Aneng AN8009 to back up my main handheld DMM - an HP (none of this Agilent/Keysight junk) 974A (with ProbeMaster leads). I'll keep the 974A for when I need to work on high energy stuff, but the AN8009 has several features that the 974A doesn't. I could get the thermocouple probe for the 974A but it would cost me almost 3 times what the AN8009 cost!

I have been on the hunt to find a broken piece of HP test gear to get the pushbutton caps to replace the broken ones on my HP 3312 Function Generator.  I was at the local surplus store and found an HP 5314A frequency counter that they hadn't looked at or priced yet.  After an inquiry, the owner said he would look at it and let me know a price but it would take a day or two.  I was getting ready to leave and saw he had it powered up and after saying he still didn't know if it worked, I could have it for $20.  I bring it home and make the mistake of hooking it up to a function generator for kicks.  Of course it works.  Now I have 2 pieces of gear that need the button caps. |O  The surplus store has 2 HP pulse generators that look good at $40 each, but I am afraid to bring one home and find out it woks also.  I hope to find something cheeeeeep at the Orlando Hamcation next month.

None that I'm aware of, there does exist many tables for various ESR values v Capacitance value but each manufacturer appears to have different values, these can be found if you google for them. The ESR is most critical value, it can effectively kill a piece of equipment if this value is high enough, particularly on power rails, instead of offering any AC ripple a route to ground, it shuts that route off and the AC gets into places where you don't want it to with dire consequences.

3D print replacements? Or consolidate the original caps to one of the counters and get new ones (which likely won't be tapered like the HP ones, but still fit on the switch shafts) for the other.

 :-DD That is the problem with quality gear - they actually survive the passing of time. I am on the same boat and I always promise myself to sell them before I get too attached. Obviously that does not happen...

US is a paradise for such gear, especially the local ads.

Those kind of pushbuttons are common, maybe an industry standard, and with a little digging you may be able to find some caps that will fit the plungers and work as a replacement. I seem to remember seeing some that were trapezoidal shaped when looking to fix my E3610A power supply. Or if you replace all of them, maybe regular rectangular types would look okay. Painting will probably be necessary for a color match though, all I could find was red and black.

Replacement caps on the bottom unit.

Sometimes those stores have insane prices.  I don't recall the details now, but I remember going to one such store in Los Alamos years ago, around 2003 and they had total junk the the prices were insane.  There wasn't anything remotely useful or in decent condition at any price, not even worth haggling.

I have tried looking by part numbers and there hasn't been any love on that.  I was figuring a cheap piece of BER gear would do the trick.  Not everything at the surplus store is working but everything I have bought has been or just needed some basic maintenance.  As far as 3D printing as bitseeker suggests, I don't know anyone with a 3D printer.  I could care less about color matching.  Anyway, I can still  engage the buttons with broken caps.  Patience will be my reward.  Besides, the Orlando Hamcation hamfest is next month.  I might be able to find something there.

Here is the data sheet for the C&K F series pushbutton switches. I think most switch manufacturers make a version of this type. Page 6 has the caps. A little measuring and you may find one that works. That's what I did. Mouser stocks some of these and they don't cost much (under a dollar).

It looks like I can get replacements for the 5314A that should fit but the caps for the 3312A are smaller than what that is available.  I have a starting point.

Totally non electronics, but I went shopping this morning, and the store had roses on reduction, 50% off. Did a little talking with the store manager and got all 19 for even lower, $1.50 each instead of $6 regular price.  Been doing a little gardening now, and the rain this evening will so the watering as well for a number of them. Only thing wrong with them is the blooms are all finished, and they are due for rotation 4 Feb for new stock. They can flower now for me and the neighbours to enjoy instead. 7 pots left to do tomorrow, after I get the spade out, as I planted the rest by hand into beds or other pots.

A mechanical ventilation unit, as the old one broke down this morning. Something with the motor that halted when in 'slow' mode. The motor - controller unit is easily replaceable. It takes 30 seconds to separate it from the plastic unit that holds the tubing. However, the replacement part is not in stock, which I can understand, but is also €6,- more expensive than a completely new unit  :--  Something is really off in the state of Denmark....

Anyways, I bought the complete unit. Which sucks big time. And that is exactly what I want it to do  :D

These folks don't seem to be very sensible. I was bidding a more realistic price for a unreasonably expensive counter a while back and got shot down. A few weeks later they discounted the counter, but increased the shipping to an unrealistic number, basically ending up at the same price. I really don't like it when they try to pull the wool over your eyes that way. Since, the price of the counter has been steadily dropping, and after a few months it's now approaching what I initially offered for it.

I can't feel sorry for them. They wanted it all and ended up with nothing. As you say, it's generally old junk for top dollar anyway and their MO isn't how I like to do business.

A week or so ago I finally got up a multi band antenna - so it was worthwhile getting out an old boat anchor I scored a while back, a Yaesu FT 101. The last weekend I have spent trying to get it in order.
The lower sideband oscillator isn't oscillating.  |O
I have desoldered and checked the transistor, the resistors and capacitors - found one slightly lifted pad - frustratingly it works for a while then goes silent. I have 'cheated' and bought another "Modulator board" PB 1184 - the one closest to the main dial. I will prob have a go at fixing the board again when I don't feel like hitting it with something hard and heavy. >:(

I ordered one of the Hakko fx888d soldering irons today. The Mrs is getting me it for my B/day!
I have been looking at getting 1 for a wee while now wondering if there will be a noticeable difference between that and the Katsu 852d I have now, the small blue 1 not the bigger black one.
I have found the Katsu to be "ok" but I never had any other station to compare it to so am curious. I had one of those dirt cheap plug in ones at first but that was diabolical so couldn't be considered something to compare to!

It was soooo REALLY BAD!!  |O
I think I would have struggled to burn my finger with that thing never mind solder anything, it came with lead free solder too but I didn't know any better then so was really struggling beyond belief to solder anything!
I guess i'll find out soon enough if the proper Hakko is any better!  :)
I'll just use the Katsu as a second iron now and for the hot air it has.
I have heard people saying "the proper brand names are so much better" but then again I've also heard others say "the clones are fine too" so we'll see.
I'll post if I find any great difference when I get it in a day or 2.  :)

A week or so ago I finally got up a multi band antenna - so it was worthwhile getting out an old boat anchor I scored a while back, a Yaesu FT 101. The last weekend I have spent trying to get it in order.
The lower sideband oscillator isn't oscillating.  |O
I have desoldered and checked the transistor, the resistors and capacitors - found one slightly lifted pad - frustratingly it works for a while then goes silent. I have 'cheated' and bought another "Modulator board" PB 1184 - the one closest to the main dial. I will prob have a go at fixing the board again when I don't feel like hitting it with something hard and heavy. >:(
Heat related ?
Some freeze spray and a hot air gun might help you zero in on it.

Lock the hammer away to resist the temptation to use it.  :scared:

No need to buy expensive freeze spray, just use a can of compressed air held upside down, has the same effect but much cheaper.

Some years back I happened to be in the right place at the right time and scored a couple of boxes of 12 aerosols, gave one to a electronics mate and have hardly used any of the one I kept, but if I ever need it...............  :phew:

I would agree re the 'top tips' but the hardest part is indexing it.
I tried the heat technique but the components (through hole) are literally touching each other, it didn't start it back up.
I think i will replace the lot in 2 stages, 1st resistors, transistor and caps, then the crystal!    Bah humbug!

Yep, I got one of those as well, only slight problem with it is that the stand could a couple of inches higher as at full height, the field of view is still very narrow compared to other microscopes on the market. Otherwise, it is extremely good value for money.

can add your own DIY baseplate see the two screws at the base , or swivel the upright 180 degrees for more field of view, to the side of the baseplate that can be placed on a book or other item.  posted this, so others can get a better look, at the stand. 

Update-
the battery powered DVR microscope has a better optical system for focus range then the other cheap USB units I have.
this DVR microscope go's from close up of just 3mm across, focusing at distance of 3cm. wayout to 5cm across, focusing at 30cm to 40cm distances.
making it the best cheap microscope for electronics work IMO.

I actually had one of those arrive yesterday. Needs nearly full height for the Lifecam/DIYHK lense so I will be adding a block before I finally mount it on my soldering setup. Only mod needed for the cam was some longer 5mm screws.

I have some better lights on my soldering stand which will help the image too also need to get away from the Microsoft stock software.

Old HP8654A signal generator.   A bit worse for wear and storage.  Inside has some corrosion due to storage conditions and 3 of the front panel knobs were cracked.   So I opened her up and cleaned with alcohol.  Used some DeOxit on the switch contacts and 3D printed some slip-over knobs.  She is working very well with the full range of 10MHz to 520MHz and a bit more on each end to boot.  Not bad for $50 plus another $27 for domestic shipping here in Philippines.

Nice pictures of your B unit.   Mine lacks the hinged top mounted PCB.   I don't know what the other differences are.   Your's looks like it was taken care of much better than mine.  I suspect mine spent some time in an unairconditioned humid space here in philippines before I bought it.   Thankfully the oscillator appears to be a sealed unit just like yours.

Thanks.
Mine came from a customer that had a # of them in an equipment room where they 'lived' until needed for lab tuition needs. AFAICS the modulation functions in my 'B' aren't working but that's not what I got it for which is mainly for checking -3dB BW of scopes. Unless I get terribly bored it's probably going to stay that way.

The Cavity oscillator is where most of the 'magic' happens and as that's working OK I'm not planning to go anywhere near it.  :scared:

Not as impressive as your microscopes and antique CROs,

I just bought enough LED spot light bulbs to replace all 20 around my house.  Dropping the lighting from an average 100W per room to 10W per room.

Also going to replace the uplighter in my man-cave with a DC 12V 3W LED spot bulb which will run off the solar power.

Also contemplating replacing the 400W floodlight bulb in the living room uplighter with an LED variant.

Estimate total spend £60.  If I could be bothered I could work out the ROI on that, I expect it will be quite short.

Every little counts.

Clueless as to where the problem might be..

If it is running Windows 10 check if the drivers have been updated.  If so, it should let you roll back to the previous version.  Until next time they update. ..

It's Win7-64 but there is no output at all - no BIOS boot up display so nothing to do with the OS..

Replacement video card finally arrived today (GTX 1060) and is installed - works great. Nothing visibly wrong with the original on cursory examination but there's definitely no output from it, so looks like it goes in the bin :(

That's the problem with a lot of the newer stuff these days and graphics cards are a prime example, they contain heaps of the very smallest SMD parts which make for a difficult repairs and with many parts not being marked or colour coded and the lack of service manuals makes it almost impossible to identify what value a part should be, even IC's many manufacturers will wipe the marking so that they chip cant be identified.

I ended up buying a knife online and the time was right as I finally figured out what kind of knife I wanted, and then after much, much, much searching and researching I ordered a dual grit 400/2000 sharpening stone (made in Germany), and then I watched a video showing how one might want to prepare the same type of sharpening stone by flattening it and chamfering the edges.. so I ordered 100 and 400 grit silicone carbide (powder) to get to grind the sharpening stone against a piece of glass, to prepare the stone.. Well, I had fun.

The head doesnt look as wide as a rattlesnake's head is.

But its my understanding that all snakes can still bite. (even if they are not venomous)

This one looks kind of cute, though. He looks like he's wondering if he's scaring you with his rattlesnake act.

As somebody who has stared down a real (and big) rattlesnake in a battle to the death,  ;) I feel qualified to make that statement. LOL.

So presumably you escorted your guest outdoors?

How cold is it outdoors, is it freezing? if the weather is abnormally cold, he likely came in to get warm.

Ive seen fairly large snakes in my back yard too. (Not far from NYC) As big as that one. Never seen a rattlesnake here though. They are here but not so easy to find. Not like in California. (where you see them all the time in some areas)

Also we have colorful salamanders, including endangered blue ones. They all are very pretty.

Its surprising how much wild life there is around here. Ive often seen large male deer with large antlers.
Almost like elk. 

Also turkeys, foxes, and it's my understanding we also have the occasional bobcat although Ive never seen one.

A mountain lion was also found dead along a road in Connecticut in 2011, but it was determined that it had literally walked its way across the country from the Black Hills area of South Dakota by its DNA.

Yep, they are really good aren't they? Don't forget to make the changes to the earthing at the very least as the case on mine was not earthed. I know have 2 of these and and I made sure that the case was earthed on them both, I also modified the connections from the power in socket to the PCB as I didn't trust the way they were connected.

My Fluke 27's arrived today and the CAT3 one was giving strange readings but a though cleaning inside and out I'm pleased to say that all readings are within a single count now so I'm happy with that.

I was rather hoping that one was buggered beyond repair so that I could transfer the innards of my 25 to a 27 case, so I'm still on the hunt for fucked 27 with a good case if anyone has one or knows of one going please think of me?

Here's some gratuitous before and after shots.

Cubdriver, thanks, I've never had a Fluke before the 25 and always wondered what all the fuss was about. Having watched Dave tear one down and a few other YouTubers tear them down I was impressed with their apparent build quality so I decided to try one, that was a dangerous thing to do,  :palm: I became hooked on their ruggedness and they feel just like you have house brick in your hand you just know they will take whatever punishment you throw their way. They may be old and only have 4 digits and update twice a second, but thats adequate for my needs. I think that the MAX/MIN is a very useful feature for long time monitoring of power rails for instance along with the fact that unlike modern meters, they only switch off when you tell them to or the battery dies, perfect for those long time soak and measurement test.  :-+

That is definitely a nice feature.  I've lost track of how many times I've found myself cursing my 77II when it decided to take a nap while I was using it to monitor something. I think you'll also be pleasantly surprised at how long the battery lasts, even without auto shutoff.  They seem to go on operating forever.

Just received a Quicko T12 OLED soldering station, 9501 handle and 5 assorted T12 tips from Ali (https://es.aliexpress.com/item/QUICKO-STC-T12-OLED-Digital-Soldering-Station-T12-9501-handle-soldering-tips-108W-big-power-lead/32837320948.html?spm=a219c.10010108.1000016.1.57d0e6d4WiR5mk&isOrigTitle=true). It is surpisingly small and so are all the tip points. I think I'm buying more tips with more sensible tip sizes, i.e.: bigger!

This thing works very well, very quick warm up and easy handling.
Yep, they are really good aren't they? Don't forget to make the changes to the earthing at the very least as the case on mine was not earthed. I know have 2 of these and and I made sure that the case was earthed on them both, I also modified the connections from the power in socket to the PCB as I didn't trust the way they were connected.
Yes, that's definitely in my to-do list.

I got a 1.6mm chisel tip for my Hakko 888.  8)

It's £17.50 to get a genuine one!! I can get 10 for a fiver or whatever from Fleabay but they are crappy copies and they are total guff! 
Proto-PIC was doing the genuine Hakko's for £12 and it's only about 20 mins from me so super fast delivery but they seem to have stopped for some reason! They only have the conical ones in stock now and I have 1 of them which seems to be a good all round size. I have the 0.8mm and 2,4mm chisel tips but sods law dictates that the size in between would be a better all rounder!

I just got the Hakko 888-D a couple of days ago and thought after my first quick try out there wasn't too much difference between the genuine Hakko and the copy Katsu 852-D I have been using up till now.
I had a proper days soldering on the 888 today and there is a big difference when you are really working the iron or getting in about heat sinks and stuff like that. The genuine Hakko really comes into it's own when you work it hard. The Katsu is ok for light work if you take your time and it has the hot air too, so it will make a good second iron to have on the bench.

FWIW I know that the Fluke 87V disables auto power off when in min-max mode. I think the Keysights do, too.

One Plus 5. My Sony Xperia is becoming very slow and sluggish, despite being just half year old. The Android 7 upgrade totally ruined it, and there's no way back. After using 4 Xperia phones in a row, each with their big issues, I guess I will never buy another Xperia.
I am sorry to hear that , and i never understand why people like to upgrade their phones.Although I know what the benefits of a phone upgrade are, but it doesn't mean that any users can upgrade their phones.if so that , you can buy Samsung S8 ,It has a good phone performance,

Hmm should be nice responsive, my Samsung phone is and it's nearly 2 years old and has just down the Android upgrade. Check your storage I expect its getting full, mine still has the Samsung crapware and its a J5 not an expensive model. Check in your settings for a maintenance tab, click on it let it run, finds all kind of things and sorts it out for you.

My HTC did the Android 8 update this week too. Now all the icons are round and symbols look crap if they were meant to be displayed in a square. What is it with round icons now? Youtube did it too, so you are forced to shrink or redesign your icon to something circular. Check out mikeselectricstuff on youtube as a classic example of messing things up by forcing roundness.

The 87V has a power on option to disable auto power off. That's very useful. Min/max is a another useful feature indeed, just like the autohold feature. It seems the 27 has all of these features too. Even though the Fluke feature set is sparse compared to some of the competition, it seems quite well chosen.

These folks don't seem to be very sensible. I was bidding a more realistic price for a unreasonably expensive counter a while back and got shot down. A few weeks later they discounted the counter, but increased the shipping to an unrealistic number, basically ending up at the same price. I really don't like it when they try to pull the wool over your eyes that way. Since, the price of the counter has been steadily dropping, and after a few months it's now approaching what I initially offered for it.

I can't feel sorry for them. They wanted it all and ended up with nothing. As you say, it's generally old junk for top dollar anyway and their MO isn't how I like to do business.
The idiots are at it again. They relisted the counter at a discount, but the "original price" is suddenly higher than it actually was for months. Horrible business ethics.

Bought a cheap 9710 Maynuo electronic load. Chose this one thinking I would just use a standard USB>Serial convertor... er, wrong! Why would they use a TTL level connection (with a DB9 connector that you could plug a null-modem cable into and blow it up) is beyond me. Oh well, even after buying the correct convertor cable it was still cheaper than the 9711 at the prices I can see. Oh, and the 'UK plug' was anything but.

Yep, but they do sell in the end and they have reasonable good feedback ratings, perhaps we should open an Ebay shop in France, seems to be plenty of people willing to be parted from their cash for items that we would consider worthy of boot sale or just binning over here.

But it’s not necessary to disable auto power off for min-max on the 87V, as I said already. Page 13 of the manual (http://media.fluke.com/documents/80v_____umeng0200.pdf#page21) says:

Automatic Power-Off
The Meter automatically turns off if you do not turn the rotary switch or press a button for 30 minutes. If MIN MAX Recording is enabled, the Meter will not power off. To disable automatic power-off, refer to Table 4.

According to someone who bought directly from Maynuo and was told this, the 9710 is built down to a price for the internal market. Due to not having to send the thing halfway back across the world, providing warranty isn't as much of a hassle as it would be for international customers. They can thereforetake more liberties with the components they pick.

Of course, that could just be a nice story to get westeners to pay more for the same device. I don't know. The story might help you if you end up running into trouble with the device.

I hope I didn't ruin the purchase too much  :-\ I don't doubt it's still a nice device to have.

Not too worried TBH, although I find it difficult to believe they would go to the trouble of having separate assembly lines. If specific for the China market a front panel in English seems a bit odd. Anyway, whilst not exactly a consumable it's not a huge financial investment.

I will make the checks as outlined in the post above - thanks Blueskull :)

Didn't like those big binding posts much (for general use, I know they're higher rated than most 4mm banana plugs), So I made an adapter out of 3mm copper plate. Can now use either 4mm banana plugs or the standard binding posts.

I purchased a Maynuo 9710 about a year ago.
Took it apart and checked all the usual safety suspects.
Nothing bad found and the build quality was pretty good I thought.
I have used it a fair bit and it has performed well.
As a precaution I never leave it unattended when loading more than a 10 watt test.

A number of members round here have been purchasing Andonstar digital microscopes lately.
My turn...
If I spend long work spells in front of my Olympus SD30 I get a sore back and neck from continuously leaning in to it.
I thought the video display style might eliminate some of that strain.
We shall see - I have a number of SMD boards to make up this weekend.
Frame rate is perfectly acceptable for soldering and there is plenty of space between the stand plate and the lens.
Apologies in advance for the closeup shot - it is of the actual LCD display.

1.5v=827nm, this board is for an IR camera to see it. It's designed for skynet.
I don't know about skynet, its being sold as a 5v step down to 1.5v adaptor which it seems to be doing as I'm 1.8v out open circuit but you could be right about the LED as I confirm it is not visible with the naked eye but neither can my phone camera which does detect infra red pulses from remote controls.

My bet is it was designed as a general purpose board, and the LED was put in when they made trhe 5V to 3V3 version, which would light almost every LED at good enough brightness with 3V3 on the output.

Myself today got an AVO8 meter, in good working order, in the original Samsonite case, with the original leads, and one croc clip end and 2 pointy ended gripper tips. Actually tested it as working, and used it as well, though the probes were more used as a set of connecting leads in an impromptu bit of lamp testing.

Now will open it up to see if the batteries are in there and leaking.

Swap meet day at the radio museum.  A pile-o-stuff that I need like a hole in my head.  I gave them $10 for the Atwater Kent battery eliminator, $5 for the Simpson signal generator and the Hickock and Motorola control panel were bound for the dumpster and will likely be parted out.  (I have another of the Hickocks at home awaiting restoration.)

bought a quick 861dw hot air station at eleshop.nl .
as reviewed and advertised by Louis Rossmann...
so far very happy with it, this thing deserves its name : "quick" !

Quick cleanup of the AVO and looked in the battery compartment. the 15v battery ( eveready) is not leaking, but did not check the actual voltage, will save it for later when checking the meter a little better, but it probably is reasonable on most ranges in any case, or about as good as most analogue meters of it's vintage. Case cleaned up nicely with some application of Teak oil, but I will need to restitch a corner a bit, and missing the carry strap. Low resistance ranges are done by the big D cell battery, and the one in there is a Duracell unit, made in USA Bethel CT, that had an expiry date of March 2004. Just started leaking a bit, the negative terminal is discoloured, and the battery contacts have a slight green blue film to be cleaned off them. Battery still works, 1.526V open circuit, and still capable of delivering over 4A into a test load. Going to it's new home now, and after it has been filed in the round file it will relocate to a nice final resting place.

Didn't like those big binding posts much (for general use, I know they're higher rated than most 4mm banana plugs), So I made an adapter out of 3mm copper plate. Can now use either 4mm banana plugs or the standard binding posts.

Nice adapter, Chris. Dave showed a PCB-based adapter that someone made for that purpose. I like your solid copper plates quite a bit more! :-+

the first result from google was eleshop.fr, which redirected me to eleshop.nl...
in fact it's eleshop.eu !
The french sellers don't seems to like recent devices, they only sell well known brands like weller or jbc or velleman.
I could also buy it from Louis directly, but the hassle of taxes and duties made me run away from this solution...

Bought a cheap 9710 Maynuo electronic load. Chose this one thinking I would just use a standard USB>Serial convertor... er, wrong! Why would they use a TTL level connection (with a DB9 connector that you could plug a null-modem cable into and blow it up) is beyond me. Oh well, even after buying the correct convertor cable it was still cheaper than the 9711 at the prices I can see. Oh, and the 'UK plug' was anything but.
As far as I understood, the Maynuo 9710 is meant for the internal Chinese market. Aren't you worried about its durability?

Hm. I didn't know that - bought it in the UK not from China. I'll open it up and see if there are any obvious faults. It didn't explode when I powered it up...

I bought a Maynuo 9710 about a year ago. I've compared it to a 9711 from a friend and they are identical. We could find no difference in the soldering quality, parts used or performance. I have used it extensively over the year because I had several PSU / DC/DC converter projects and it has served me very well. I'm glad I didn't spend the extra money for a 9711.

Getting a working power sensor cheaply is the hard part in my opinion. They get killed from excessive power, are beyond economical repair if the sensor is blown, and many are offered untested, as-is, making buying them a gamble.

Yes, I know.

I hope that the HP 8482A Power Sensor sold as "Tested and working condition, pulled from working environment" I just bought on *bay for ~130EUR (after some negotiating with the seller) +35EUR shipping + customs ( :'( how much..?) will proof being a good buy. *fingers crossed*

A 11730A Power Sensor cable (50EUR incl. shipping) will be shipped tomorrow.

Power Meters seem to be like lathes:
The machine itself may have a given price but the tools and accessories will easily multiply that.  :palm:   :popcorn:

Tested the AVO 15V battery, and it is dead, shuffled off this mortal coil, gone to meet it's maker Ever Ready. Replacement will be easy, going to strip the case off carefully, then remove the stack of waxed prismatic carbon cells inside there, and grab 5 Cr 2025 coin cells as a replacement, fitting them into some shrink sleeve and using a pair of contacts each end to go to the original terminals. Then will make up a new box to suit and put the stack in there. Now to go get a pack of those expensive D cells, or get a pack of C cells ( a lot cheaper) and make up some adaptors to make them fit in place of a D cell, or order some AA to D adaptors on fleabay.

Sean, in my AVO 8 Mk 5, I made a stack of LR44 button cells and added a bit of copper tube to match the 15V cell length and then held it all together with some heatshrink.
Over here we can get a card of 10 of LR44 for $2.

I have no idea how big your hands are, I don't know any thing about ring size, but I know you are definitely right! because my hands are so small, even smaller than most chinese women's hands.  :-[

Now I have to buy the polariser that fits the led lights and sensor.
Do you know the diameter of the threads in the camera (assuming C-mount)?

I ask, as there's a stable supply of Japanese made polarized filters on eBay for certain sizes. 38mm fits Amscope and similar brands for example (used to attach Barlow lenses and filters beneath the objectives on binocular and trinocular models).
I will use a simplier way :

Original Thaler Corp VRE305 Voltage reference.   I bought it from a seller in Israel for $35 shipping included.   This is opposed to $75 for the new APEX VRE305 from Digikey. 

My APEX chip is drifting well out of specification...about +100uV since Jan 2nd of this year.  Previously the IC had been in an aging fixture for 5 months.  During that 5 months it also drifted up...roughly +300uV.   The specification is 6ppm per 1000 hours...it's pretty close to 1000hrs from Jan2 to now and 6ppm is 30uV.   A factor of 3 high.   5 months would be 3600 hours or 22ppm or 110uV...again about a factor of three high.   This is actually my 2nd APEX VRE305.  The first one was replaced by APEX because its output voltage was a factor of 2 out of specification from the get-go.  APEX was responsive to my complaint and sent the replacement FedEx to my home in Philippines.   They only required that I mail them the old chip for testing.   

I have heard that the original Thalar chips met their specifications, so I will test this one for a few months and we shall see what happens.

Got myself a Tefifon and a Tefi cartridge because I saw Techmoans video about it and it was cheap. Plus since I'm into tube radios it fits quite nice into the scheme of things, because one way to use the Tefifon was to plug it into your radio. I'm not going to do that. Because of GIS reasons.... Those are the people in Austria that make you pay if you have a device that can receive a radio or TV signal. So I will solder two rca plugs onto the output and plug them into my amp.
The Tefifon is atm with a friend, to whom I send it, because the seller shipped only inside Germany. Thanks to IRFP460  for letting me ship the stuff to you and then bring it to me  ;D Along with other stuff :D
I also got myself some glass beakers for chemistry stuff.

Four HDSP-6508, 8 digit, 16 segment bubble LED displays.

Seven segments bubble LED displays are fairly common but alphanumeric display aren't. Two years ago, I missed out on a nice lot on eBay. Not this time.

I probably paid too much for them but I got them in the collection this time (well, almost, I'm still waiting for the parcel to get here)

A few things for a regulated-temp, vacuum hold-down hotplate I'm making. Hopefully to be able to non-destructively disassemble an iPad Mini 3 and other such glued-together devices. Most of the hotplate bits are salvaged stuff I had lying around, like the setpoint controller, timer. heating base plate, SSR, buttons, etc. But for the construction, assorted mechanical stuff:

* Sheet of 6mm thick aluminum. An offcut.
* Two sheets of silicon bonded mica. One 5mm thick, the other 3mm. Also offcuts.  I only needed a little of this, but think it's bound to be useful for other things. Expensive stuff - that's $120 worth in the photo. Biggest problem is how to cut it. Like mica washers it delaminates very easily.
* Tube of high-temp (300 C) silicone sealant.
* Bunch of stainless steel M4 & M5 screws, mostly button head hex.
* An M4 taper tap, to replace the one I ground the end off to make an absolute bottoming tap, for blind threaded holes in the 6mm aluminum sheet.

I just ordered five 0.2m GPIB-cables from overseas (US). Special feature: The connector at one of each cable has a 90° cable outlet.

And yes: GPIB isn't dead. In my opinion and for my test equipment that's awfully true.    :)

Ah, the Triax Cable I ordered in October last year was delivered to me finally.
The Triax connectors I ordered from mouser around the same time are still not delivered because I ordered the together with special LEMO connectors that are announced to be available around April 2018.   :palm:

A HP 11708 A 50 MHZ precision Reference attenuator.
Makes the 140 Euros for the 8484A Power Sensor (Option 003 -no attenuator -euphemism..) -that I thought were a good price- look not so cheap: The attenuator is 2/3 what I paid for the sensor.
Still little money compared to prices for new ones. But still real money...

Now waiting for delivery. *groar*   :popcorn:

BTW: HP 437B Power Meter and 8484A Power Sensor I recently acquired are working fine. I could verify the attenuator of my HP 3335A Synthesizer is working within its specs as far as the Power Sensor can measure (-65dBm; 3335A goes down to -86dBm).   :-+

Today because I 'need' an accurate Frequency standard to cal the 40+ year old crusty counters I own  :palm:

As it is fairly new teardown will be done to see what is actually inside the box.

Thanks, as I've been salivating for this particular 189 for years  :'(, and had been waiting to get a decent one with decent price.

At least to my self, this 189 is almost an ideal handheld DMM. I own 87V and 287, and it has instantaneous boot time and really hate 28x booting time, with an ultra sharp LCD segment display not like 28x dot matrix rubbish, size wise is equivalent to 87V's size which I personally prefer, and full of useful features for electronics activities, that made the 87V features look crude as its more suitable as an electrician DMM. And its AA cells powered too.  :clap:

Have you looked at the Tektronix 11302?
This was the last hurrah of analog scopes and outperforms the 2467B on several fronts.
It has the bright-eye screen like the 2467B, but takes plug-ins.
The frequency counter that is integrated is reason enough to keep it around as it shows on the waveform what is actually being counted.

Always claiming "we called but you weren't home" - No notification left at the address... The delivery address is an office with 700+ employees and the delivery dates were normal weekdays! DPD failed on the last 2 parcels, sending them back without bringing them to a pickup point. Hermes is kind of ok, but manage to not deliver occassionaly. It's got to the situation, that I will not order from ebay sellers that use GLS or DPD.

One day later DPD happened to successfully deliver a packet to a neighbour of mine.   :clap:

It's so annoying waiting for Test Equipment to be shipped and even more annoying when it doesn't show up.  :'(

So you'll have to wait for new messages about things I bought 'til they hopefully show up..

In Germany it has got to a stage where DHL is the only half trustable delivery service. GLS have failed to deliver the last 14 parcels to me (over 24 months)! Always claiming "we called but you weren't home" - No notification left at the address... The delivery address is an office with 700+ employees and the delivery dates were normal weekdays! DPD failed on the last 2 parcels, sending them back without bringing them to a pickup point. Hermes is kind of ok, but manage to not deliver occassionaly. It's got to the situation, that I will not order from ebay sellers that use GLS or DPD.

How the hell do places like that stay in business?!?  That sounds like unbelievably atrocious service.

Sadly that happens very often here in the UK.

Retractable 4.5m, Cat 6 cable assembly.
Retrieved from recycling... network connector was dangling off, re-terminated and all good. Nice metal Molex connector that was a breeze to re-terminate.

Destined for the workbench... if I can find a spot to mount it.

Some RF attenuators and a DC block...which lol...is rated from DC to 6Ghz.   You'd think it would block DC and low frequencies right!   Attenuators are all 20dB, 50W, 10W and 5W.  It's on my To Do list to eventually post spectrum analyzer data on a variety of attenuators, both US bought and Ebay sourced.

Hermes: Delivery on the last mile for an international packet from the US:
The driver has marked the packet is delivered to me (not a neighbour!) at a date/time neither me nor my wife were at home.   :wtf:

In my opinion that's only because they're cheap enough and for the companies shipping with these this might cost less than sending with DHL or UPS (quite reliable from my experience) overall.
But only if you do not take customer satisfaction into account.   :(
I'm quite pissed off with Hermes but I have no choice when I'm ordering something from ebay that's shipped by ebay over Erlanger, US.  :palm:
And as we found out in the TEA-Thread: The US have a very big and tempting market for used Test Equipment in comparison to Europe or Australia/New Zealand.  |O

By making contracts with the postal services of other countries. So if someone sends me something from the UK with Royal Mail, GLS have a contract to lose it once it gets to Germany. In the case of GLS, I've complained every time, I've been told that the driver was on his last warning, that the driver would be disciplined, etc etc. I even set up a CCTV camera to see if the van even passed the house (it didn't), yet they claimed that he tried to deliver it and we weren't home and no notification was left.

Useless wasters.

Damn.  I'll never bitch about UPS SmartPost or FedEx SurePost again - they may take an extra day or three, but it typically gets here.  DHL is the one I dread here in the US - at a past job they used to routinely deliver our packages to a different company with a different name at a different address (about a mile up and across the road from our facility) and I'd have to go retrieve them.  Some Amazon sellers use them for books; my 'Art of Electronics' took about a month to get to me in CT from Chicago, which is about halfway across the country.  I suspect that they taped it to the back of a tortoise to make the trek.

Here in the Philippines they don't even attempt to deliver.   All packages are held at the main city post office where you have to collect them.  You might get a postcard or text message if they are feeling like it... telling you to come pick up your package.  Usually I don't get one...I just come every week and check. 
If you don't manage to pick it up within a month, it can be destroyed if they want.   Oh...and you have to pay the equivalent of about 1 Euro for each package, no matter what size on top of whatever postage was originally paid.   If you package is worth more than about $200US you have to pay duty as well...15% usually but can be more.  For some cheap Ebay items this doubles the cost.   
Add to all of this transportation cost of a trip into the worst traffic part of town.   Fed Ex on the other hand here is excellent, just expensive.   You have to pay an extra $11US for each box on top of what the shipper originally paid, plus duty of applicable.   That why we call it the Fee-lippines.

That is very likely another reason if not the main reason.  :rant:

DPD is solved now: A neighbour handed the package to me because he found it in his post box. It was a padded letter.
Roughly 40 minutes later a DPD-driver rang at my door to find out about my complaint personally.
He was apparently glad I could give him notice that I had received the package short before, finally.
When I signed his notice that I had received the package I checked the archived signature that was left when the package was delivered originally: It was a unreadable scratch of two or three characters and clearly not my signature.   :wtf:  :--

Ok, that's what DPD should have delivered correctly:

A 0,5m N-connector (m) to BNC (m) low loss Highflexx 7 cable.
My HP 437B measures -0,03dBm@50MHz: within/slightly better than the specs.   :-+

Hermes: No reaction to my complaint besides the ticket notification since Wednesday. Oh boy..

Few used low resistance shunt resistors dismantled from a big factory machines, made by PCN Corporation, Japan. Just heard this company, is it reputable ?

One 1K Ohm (30 Watt), two 10 miliOhm (30 Watt) and two 1 miliOhm (bigger ones 50 Watt), with 0.1% tolerance and TCR of 30 to 50 ppm/K. (PDF Spec (http://www.pcn.co.jp/PCN_PDF_E/e-pcrh.pdf)). All have the extra sense wires with teflon coating.

Put a TO-220 body for size comparison, biggest resistors in physical I have, an impulse purchase cause they have nice 1K, 0.01 and 0.001 numbers.  :palm:

That is massive for 30W, the ali "100W" resistors I bought look to be about 1/4 of that size. Wonder why they didn't just run the sense wires out one side though, maybe it would get too hot in the middle.

Yep, was shocked when the 1st time I hold them, as I bought online and the seller didn't provide the size as a clue. On weight, the big one is almost 1 Kg (900 gr). Have to admit by quick glance, they look like those crude dummy load resistor.

Actually the TCR are specified max out only at 100 C, which is way-way too low compared to ordinary big wattage dummy resistor which sometimes can withstand way higher temp.

The biggest one, in the datasheet, its specified max wattage on free air without mounted to heat sink chassis is only rated for 20 Watt.  ::)

Another photo attached below for a clue compared to TO220 on how huge this things are.  ???

You're probably right, maybe for maintaining the TCR at 30 ppm/K too I guess.

Just kidding, may be because of Japanese love perfection so much, that the two Kelvin sensing wires must be "symmetrically" installed too.  :-DD

To keep temp rise down - big thermal mass, increased surface/heatsink contact area.

Or just for current carrying capacity - 1milliohm at 50 W = 223A

I guess so, maybe adding in a Titan V and populate all RAM slots. A few Intel 900P for storing movies and a 40Gbps QSFP+ NIC are absolutely necessary.
:)

That would be quite some system.

Being slightly more sensible I covered some of the rationale in my post bemoaning the lack of great choice in 8-bay NAS cases in the market at present. The reason for the system upgrade is I'm running ot of disk space on the existing box. The reason for the overkill CPU (for a NAS) is that I'm trying to consolidate boxes so it will be my go-to PC as well as running a media server, holding the DVD and Blu-ray collection (still have more than 70% to go and the existing box is filling fast), transcoding to h.265, some video editing and hosting email/imap.

I got the "K" because I'll probably want/need to undervolt it if possible - at least initially. Air cooling is always going to be compromised in this case - liquid cooling might just be possible but it will be very tight and I'm got going there in the first instance.

I know it's not exactly best practice to use a server as a production PC but I've had a server/work PC split for the past 5 years and it hasn't turned out to work all that well. Most of the time if I want to quickly check a web page I'll just turn the monitor on and flick the KVM to the server as it's faster than booting the "big" PC, even given the fact that it has an SSD. Also it's running out of disk as well and I figured it was better to kill two birds with one stone.

Fortunately I don't play PC games so the one thing I don't need to try to squeeze in is that Titan V

Yeah they should easy do that with ~200% overload for a short duration. I wouldn't trust that they'll meet original tempco specs later though without some checks.

Thanks, as I expected, since as datasheet stated its capable of maintaining the +/- 0.1% tolerance up to twice the watt rating, and up to 5 seconds. Also up to 150C for 2 hours at the same tolerance.

5 seconds is more than what I need, as I just want to take a scope single shot during the motor cranking up and starts the engine, that should be way under 5 seconds right ? Did I miss anything ?

That's a pretty good spec IMO.
Don't know what I was thinking and changed previous comment down to 100% (double the rating).

If it not a diesel that have a higher draw you should be good to go.

This Hermes story is becoming strange..

My wife and I were having lunch when the door bell rang.
I walked to the door immediately and found a big cardbox package right on our door step. Our flat is on the ground floor, so I can check the door of the house easily: there was nobody at all, the door was closed. The person who put the package there and rang must have been really rushing out of the house. I walked back in and opened a window to look if there was somebody hurrying down the street but again: nobody at all.   :o

The cardbox package is the missing Hermes package. It seemed untouched and after I opened it I still had this impression: It was nicely packed and it didn't look like beeing inspected be someone else before.   :-+

No surprise, Hermes still hasn't answered my complaint yet.
They told me I could use the email with the complaints ticket notice to reply to them if the package should get to me.   :-DD
But I won't do them this favour: I *!Q#X?&!* do want to know to whom the package was delivered originally..!   :rant:

After all a happy end:
I now have an Agilent 6063B 0-10A,3-240V 250W DC Electronic Load in nearly mint condition to be used.   :-+

By the way: According to its serial number it's my newest piece of Test Equipment besides my Fluke 85 III, 87 V and other miscellaneous hand held Multimeters.

Here is a pic of the front and back panel to give you an impression:
(https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=395977;image)
Only some sticker residue right the LCD that will easily be removed.

It was offered on *bay as "the 120V-Version".
I guess that's why I had not much competition on that auction and won it for 167EUR.  :)

And it was indeed the 120V version. -But it's easily convertible to 220V/240V by switches inside -what I did.    ;)

With this price and the shipping costs plus customs (~ half of the price) the over all price is quite a bargain for me: I also considered to buy a Maynuo or Itech and their 300W-Versions go for more..

On the other hand, the 6063B is unquestionable solid and reliable.
I tested it using two HP 6643A Power Supplies for giving 240 Watts to it and it blew that power right out of its back vents for over two hours without a moan.   :-+

With its Transient feature I'm now able to do things I wasn't able to test without it. Very handy.  :-+

Happy.  Addiction satisfied once again  :)

I now have an Agilent 6063B 0-10A,3-240V 250W DC Electronic Load in nearly mint condition to be used.   :-+

Glad it finally arrived. It really does look like new.

Quote
It was offered on *bay as "the 120V-Version".
I guess that's why I had not much competition on that auction and won it for 167EUR.  :)

And it was indeed the 120V version. -But it's easily convertible to 220V/240V by switches inside -what I did.    ;)

That's a great deal! I guess lots of people don't read the manual prior to purchase. That's a good thing. :-DD

Happy.  Addiction satisfied once again  :)

That seems like massive overkill for a home NAS. I guess maybe if you also use it for other things it makes sense.
Overkill is fun  >:D

Nice looking case.  :-+
Nice looking, yes.

It's cramped - my fault for liking lots of CPU and disk in a small box, there are no individual hdd activity LEDs which is a pain, the front surface is matt, almost rubbery and it looks like it will be a finger print magnet and not all that robust against scratches, cable management is somewhat non-existent, thermals are going to be "interesting" and it has an odd extra USB connection going up to the front panel - when I looked there is what I suspect is an RGB LED and an empty 8-pin DIP socket which I suppose is intended to contain some sort of interface between the two - I've had a quick look and can't see anything standard so i suspect it needs a microcontroller there.

But I wanted small and it meets that criterion - the other problems mostly flow from that choice so I'm not complaining as such. If I can get everything squeezed in I'll be happy.

A NAS has been on my list for a while.  I have 8 SATA drives in my PC and an external and most of it is not shared.  The plan is to move to a NAS for everything except OS and Games which will go onto SSDs.

The downside is NASes are either weedy, plagued with nonsense software or really expensive.

Building my own is a nice idea.  I tried a Raspberry PI.  It just can't cut it under heavy interactive load like browsing video thumbnails on a smart tv would just lock it up with 12 fileserver threads hitting it simultaneously..

So I understand the want for some power too :)  An i7 ... a little overkill though.

A Pi is probably a bit underpowered for that - makes a nice enough email server though.

I was only half joking about the i9 - I did actually consider it briefly before deciding that it wasn't going to fly, but there actually are mini-itx X299 chipset motherboards  :scared:

I actually quite like the existing set-up - an i7-3770T in a Morex Venus 669 case with the original 5.25" bays filled with an Icy-Dock 3x 3.5" caddy and the original 3.5" bay taking a 2x 2.5" caddy. Works well, not too cramped inside, temperatures absolutely fine. I just can't get more disks into it.

I am certain URI outbid me for the 6063  |O I too was shocked noone else was bidding on the unit so I thought I was going to steal it at $150...nice ctach mate, Im kicking myself!

Bits and bobs to make a dim bulb tester and an LG FG-7002C (putting all the fun back in) function gen for hundred quid were today's purchases. 2 MHz is plenty for me at the moment. I have an old TTi one that will go a little higher but it has no sweep. The LG also has CMOS/TTL output. That's my excuse and I'm sticking to it.

Caddock has a line of 0.1 and even 0.01% abs accuracy but they are still just 5ppm and cost at least $20 each, so I think this lot was a good buy. They are getting increasingly harder to find as well.

I may just keep two or three of each and relist the rest to recoup some of the investment. I don't really have a plan for them, but wanted a variety for experiments. I am currently rebuilding the Scullcom/Barbouri Millivolt Meter so I will get to play with various dividers and see how they behave.

LOL - perfect timing - I just powered the 8662A up tonight after changing a cap on the display board.  I still need to actually connect it and see if it does anything, but for the moment no more smoke came out, so that seems a positive sign...  (I think hope the extreme right one is supposed to be out except in certain conditions, but am not completely sure at this point.  Need to dig into the manual.)

Oh!!  Yes - Something like a frosted NE-2 installed lengthwise into a holder so you're viewing the top of the lamp.  I just looked, and apparently I've never taken a good photo of one of them.  D'oh!!  Just popped off a few with the iPhone:

Lit through the filter with a flashlight:

And actually powered up and lit :

Yeah, the MD1000 is really just a box of disks, PSU's and a couple of SAS expanders - no "intelligence" as such.

Actually someone I knew built a NAS from something similar - in this case http://www.supermicro.com/products/chassis/4u/847/SC847E16-R1K28LPB (http://www.supermicro.com/products/chassis/4u/847/SC847E16-R1K28LPB) - apparently the fans sound like a jet taking off.

I've finished for not - everything squeezed in and cables tied off neatly and an OS installed. My final view on the case it that it's OK, a bit pricy but OK - it does, in fact, have per disk activity LEDs - I didn't notice the tiny light guides in the disk caddies.

So there are just two outstanding issues:

1) The Toshiba N300 8TB drives, I realise that there are a few comments on Amazon to the effect that these drives are, or can be, noisy but I thought "no modern HDD is that loud". Completely wrong - these emit an irritating deep clicking noise on head movement. It was especially irritating when ext4 was doing its lazy table/journal initialisation - after a few minutes I just wanted it to stop. I see now why one reviewer said he dreaded turning his PC on, it was like listening to someone incessantly grinding their teeth. It's a bit better now the initialisation is done but I think that they are going to have to go back.

2) Thermals Undervolting wasn't stable, although there were some oddities which I need to look at. Keeping the lid on thermally needed a massive underclock. Sadly I think that the NH-L9i is not up to an 8700k. To be fair noctua say the cooler won't work with an 8700K citing a max TDP of 65W (but confusingly they do claim it is OK with 91W TDP Skylake CPUs).

Hence a re-think might be called for. The NH-L9i is probably the best, indeed almost the only, cooler for its 37mm height and so if it can't cut it I'm not sure what will (suggestions welcome). In another case I'd possibly try a higher airflow fan on the same heatsink but here isn't room. Liquid cooling probably isn't an option - even if you could get a block on the CPU it would not be possible to install a radiator (even outside the case which I thought might be possible).

Even in its current hamstrung configuration the 8700K is an impressive CPU. It is doing a software h.265 encode more than twice as fast as my mildly OC'd 4770K does and would be more than 3x as fast at stock clock speeds. More impressively the hardware encode (which I can't do on the Haswell chip) is managing 127fps which is about 25x faster than the earlier chip could do in software.

Ultimately I'm going to have to admit defeat, I think, on the idea of putting an 8700K in such a small box and probably move the 3770T motherboard into the U-Nas case. I think that will work well as the NAS server CPU and will be a really good match to the case. I just need to find the 8700K and its motherboard a new home so really I just need to buy a mid sized case (of which there are loads of nice ones without breaking the bank) and an ATX PSU (ditto).

That's neat. First time I saw a closeup of one of those dot LED digits. Didn't know there was a little controller on each one.
Very neat but overly complicated and expensive to make. :popcorn:

Yep, which is why it's great to get gear that already has them.
Unobtainable as spares though I expect?

This weekend I have been spending on all kinds of things most of them are either directly or indirectly electronic related items, here the directly related items:

Shit loads of 1% metal film resistors for stock, to many values to list, fume extractor/filter, AC power meter, Car USB charger, PCB holder and some heat shrink tubing.

 
 

I have that PCB holder...very handy! A decent size too, i'm sure you'll like yours too  :)

The raised board holder for bigger boards work nicely. Part of the reason I arranged my DIYHK camera stand was to get under it.

I bought some replacement/spare fuses for my HP 5314A counter and 2 sets of the Pomona 122505A/506A retractable sheath banana plugs for my Brymen test leads.  I was going to try a set of the Probemaster 8000 series but I figured that since I was already paying for shipping on the fuses, I would get the plugs.

Actually, still being made by Broadcom/Avago.  Close to $40/each from Mouser, though, and no lead time shown.

That's the case for the ones in the 8662A, and also those in the 8673C that I know of, but not all of the dot displays are individual digits with controllers on each.  Those on the 5300A measurement system display unit, and the 34740A display units (again, that I currently know of) are simply multi-digit multiplexed dot displays, with each digit split into left and right halves, and driven by logic that is external to the LED display itself.

I am so broke all I could afford was a few more holes and some 1/4 BSP threads  :-DD

Might spin the camera base around to move it back on the mat a little but the cranked Swiss cheesed base and threads works a treat focal distance about 10mm below the surface :-+

I have a couple of vintage 555 timers for PWM and a few high power LED's for a little more lighting but version 2.01 is sorted for use.

Part 1 of the Great Amazon Drok £3.99-for-anything sale :)  5 x DPS5015, 15A motor controller, and a Tesla lighter. Also bought one case for a DPS5015 and a mini 3-jaw chuck (the latter 'cos the minimum size for my miller's main 16mm Albrecht chuck is 3mm and I got fed up with having to swap the chuck out for a smaller one when I want to drill/tap 3mm threaded holes).

Part 2 should arrive tomorrow..

My previously mentioned laser engraver has just died. I tried to strip out the control board and replace with my own, and the screw just won't loosen (tried WD40, tapping with hammer and plain brute force). The screws were hidden so it was impossible to un-tighten them without completely disassemble the entire thing, and the nuts were just too shitty that they strip easily before the screw can be loosen. I ended up sawing the PCB apart in hope to remove the screw by wiggling the corners of the cut PCB. The power saw jammed, with the blade hitting the PCB and the guard hitting the acrylic case, and completely shattered the acrylic wall.

So, think twice before buying another $129 laser engraver, at least if you want to modify it.

My next plan: build one from ground up with CNC aluminum parts and NEMA17 motors.

lol...I just ordered one here in philippines which looks like your's from the photos but was even cheaper...roughly $100.   It has yet to arrive.  I don't expect much...If it can engrave some text on plastic and wood I'll be happy.   If if can reproduce line art 1/2 decent that would be great.

Calm down. There will be another one and it might go for less because the ones that outbid you before don't want/need another.   ^-^

Of course, even the LED head, tail cap and the body are replaceable, like shorter body with different sized smaller LiIon cell. 18650 based flashlights with replaceable battery have been available for years.

This BLF A6 is community designed at Budget Light Forum, and sold exclusively by Banggood, and its on discounted price for 27 bucks. Just google for "BLF A6" for more info.

Its micro controller driven, and has different brightness setup and also memory function (the level you want when powered on), rather than have scroll thru different brightness sequence. It has battery level indicator too which I like, and etc misc features, all of these are accessible through the single tail clicky button. Even the firmware is upgradeable  ::), but I'm not interested, already feel content with current features.

URI, sorry man, guess everyone can tell, I am still steaming about that one. My apologies. Right after that loss, I found a badass BK 8614 and the guy wanted $1,000. I talked to him and all seemed well and the auction ended while I was saving my change to buy it. When he relisted it, the rpice soared to 1,550 and I couldnt get it. I blew my shot at getting it for $1,000 (well I didnt have the cash on the spot) and I am steaming about that one too...I need help!

Anyway, the Caddock thin film TF020R lot arrived today. I have ( ) qty of each the following values: (9)1k, (10)5k, (10)9k, (10)16k, (10)18k, (9)20k, (10)22k, (10)24k, (10)25k, (18)100k, (10)200k, (9)500k

Here are a few pics of a 1K (the first set I opened) on each range of the DMM. I have not calibrated the K2000 since I replaced the caps, I just reset it to factory specs and it looks pretty damn good. The 100K range shows 4-zero's but the lower range may be off a bit. Ill go through each range and use the most accurate resistors (and my GenRad decade box) with my 335A to generate precise CC as well...fun stuff ahead. Ill upload some video when I get a chance to run them a bunch of them.

I will gladly share a few sets of these with the members here. Just let me know and we can set it up.

edit 2-22-2018: I re-listed 6 lots today. Put it up for $100 OBO. ALL forum users, I will accept $20 per set, just send the bid. One of each expect the 100K, put (2)100K

I bought the NewScope LCD replacement kit for my Tek784D recently and installed it today.   Took most of the day, not because of the kit really, but because some idiot working on this unit before me stripped out a couple of screws and left one of them broke off.  Getting them out and re-tapped took quite awhile.  The kit is pretty nice and very well packed.   No instructions included in the box but a pretty decent illustrated manual is on their website.  A few steps were missing but nothing major.  With the floppy drive replaced with one of those USB units the old girl should be with me for awhile longer.   The only downside is the price...$350.   I paid about $450 for the scope last June which is a deal here in Philippines if you can find one at all.

I bought it quite awhile ago on Ebay...but here is a new listing of the same item   https://www.ebay.com/itm/Slim-Floppy-drive-Emulator-Tektronix-Oscilloscopes-1-44mb-26-FFC-1mm-Pitch/291291990998?epid=1254493285&hash=item43d25b0bd6:g:Zr8AAOSwopRYd0oS (https://www.ebay.com/itm/Slim-Floppy-drive-Emulator-Tektronix-Oscilloscopes-1-44mb-26-FFC-1mm-Pitch/291291990998?epid=1254493285&hash=item43d25b0bd6:g:Zr8AAOSwopRYd0oS)

Operation is not like the PC emulators, so be aware of that.  There is only one floppy image stored on the USB stick and you don't have to format it special.   The instructions are typical badly translated but once you get how it works it's reliable and fairly easy to use.  Cost is $95 plus shipping.   I know the slim pc emulators are much cheaper but they don't work.  I bought one first and gave up trying to make it work.   I suspect that you could buy a slimline PC emulator and mod it, but I don't have the patience to bother.

You can return it now. The 1500mW rating is not honest. The laser diode in the laser module has a CC driver at 175mA, so for a blue laser at 4V, 40% efficiency, that translates to 0.28W of optical power.

I just did a test on the module, and I was very disappointed. Reported to Amazon, requested them to delist that item and its ilks OEMed by the same company (NeJe).

I didn't order from Amazon, they don't ship to Philippines.  I ordered from a site here in Philippines called Lazada.  Return might be possible if the unit is defective, but they aren't as nice about returns here as Amazon.

Ha Ha! I have a 12 pack of the lithium AA's coming probably tomorrow! If it chews through them what I deem "too quick" then it's gone! As soon as my lithium are delivered i'll change them out, I suspect the ones in it just now will be normal AA's. They will only be put back in if it leaves/sells!  :)
I've heard it chews them like no tomorrow and also heard people who've had theirs 2 years or more and still on the 1st set of batteries too. I think a lot depends whether the supercap is ok or not as far as batteries goes. A pot luck thing! We'll see...

I have the Brymen 867s which I really like as a meter, the 289 was more because I "wanted/needed" it.....ya know "wanted/needed" or the world would end? LOL  :-DMM

If I end up not "really liking" the 289 i'll get rid. The 867s gives me all the features and accuracy etc i'll ever need.

I've had a quick go on the 289 and think i'll end up "really liking" it anyways......WHAHAHAHAHA!!!   >:D

  With the floppy drive replaced with one of those USB units the old girl should be with me for awhile longer.
Do you have a link for that USB unit? My TDS744 may need that.
I bought it quite awhile ago on Ebay...but here is a new listing of the same item   https://www.ebay.com/itm/Slim-Floppy-drive-Emulator-Tektronix-Oscilloscopes-1-44mb-26-FFC-1mm-Pitch/291291990998?epid=1254493285&hash=item43d25b0bd6:g:Zr8AAOSwopRYd0oS (https://www.ebay.com/itm/Slim-Floppy-drive-Emulator-Tektronix-Oscilloscopes-1-44mb-26-FFC-1mm-Pitch/291291990998?epid=1254493285&hash=item43d25b0bd6:g:Zr8AAOSwopRYd0oS)

Operation is not like the PC emulators, so be aware of that.  There is only one floppy image stored on the USB stick and you don't have to format it special.   The instructions are typical badly translated but once you get how it works it's reliable and fairly easy to use.  Cost is $95 plus shipping.   I know the slim pc emulators are much cheaper but they don't work.  I bought one first and gave up trying to make it work.   I suspect that you could buy a slimline PC emulator and mod it, but I don't have the patience to bother.

The Gotek emulators would likely work just fine if you ran the HxC firmware (STM32) on them instead of the garbage that comes pre-loaded on them.

http://hxc2001.com (http://hxc2001.com)

The Gotek has a standard 34pin header connector, but the Tek scopes used the "laptop" solution: 26way FPC cable, so you'd have to make an adapter to connect it.

Sometimes you find something exotic, out of the ordinary or just intreaging and can't stop buying it.

I used them about a month or so ago for a Hakko fx-888 from them but through Ebay. It was cheap but they had plenty good feedback so I took the gamble. It's a genuine Hakko and was delivered on time etc so I would say all good. They are a genuine UK Hakko distributer after some fishing around.

I hope you have the same trip with them, I think you'll be good!  :-+

Sorry never read the post properly. Glad it went good for you and the solder seems ok.  :)

Knipex tools are very nice. I have a wire stripper from Knipex: https://www.eevblog.com/forum/projects/wire-strippers/ (https://www.eevblog.com/forum/projects/wire-strippers/)
I know, you can use a side cutter for wire stripping, but with this Knipex tool it is much more fun, faster and cleaner (no indents in the metal core etc.).

An FY6600 Signal Generator

I got fed up trying to use a £3.99 Chinese sig gen kit and my PC audio to test op amps.

Figured a dual channel sig gen would be a wise idea.

I assume there aren't any major "gotcha's" with this unit?

Did you find any issues while installing the new firmware? Did you follow a YT tutorial or just know how to do it without the help?

I haven't used the Knipex ones yet, but had used the Adel type at my old job.  The Rat Shack ones I have are this style:
(https://photos.smugmug.com/Electronics/Misc-test-equipment/i-4GX2jNR/0/87fe2241/O/2018022410454249-IMG_0359.jpg)

And I was never crazy about the ergonomics of them.  The way the handles curve makes your grip more inclined to slide towards the narrow part where you have less leverage to squeeze them closed, making it more difficult and uncomfortable to use them.  And the orientation means that if you hold them cutter up so you can see what you're cutting, the widest part of the handles (where you have most mechanical advantage) is at your smallest, weakest finger, and the strongest part of your hand is where it does the least good leverage-wise. 

The Adels are the opposite - the part you squeeze falls naturally between the web of your thumb and your index finger - the strongest part of your grip.  A slight downside to them is that they have a little spring loaded clamping cap on the cutter that helps to hold the material being cut against the anvil, and this requires a slightly larger hole to start the cut, but unless you're trying to make a really tiny opening, this isn't an issue.

Yes I have owned both styles of nibblers, and IMHO, the Adel is clearly superior both in design and in construction to the generic chrome thing, at least the ones that I had/have.  I have not used the Knipex style.

Thanks for the explanation! Ironically, the nature of my repetitive strain injury weakens my index finger, such that my rat shack ones (precisely the ones you showed) forcing me to squeeze with the other fingers is probably better for me!

As for the minimum hole size: even bigger? Yeesh! I find the 1/4” minimum annoying already! :p

After 6 leaking Procell batteries killed my F289, I've never used a single Duracell. To be precisely, not a single alkaline except some Energizers in cheaper devices.
All my devices that worth something that I don't want to lose, I use Energizer Alkaline Ultimate now. Energizer claims they will never leak.
They claim if the alkaline leaks, they cover your loss. If the lithium leaks, that's impossible. That should mean something.

Same here got a bunch of duracell AA/AAAs killing lots of things in last year they just died in low power devices within 6months that usually run for 3-5 years, and all cells had exp date like 2020+..

Edit: after this happened now I remove all cells from all DMMs, etc if Im not planing to use them for some time, and switched to eneloops/lithiums where possible

I recall there was a sizable thread here about leaking batteries. Although people have varying experiences with this or that brand, in aggregate it doesn't matter. Alkalines have a risk of leaking. If you value the device, don't use alkaline batteries.

Yes, some manufacturers claim theirs don't leak and provide warranties to cover the loss from leakage (I've used them before when those "guaranteed not to leak" promises failed), but you'll have to go through the time and hassle of the claim process.

Of course, if you're not going to use a device for an extended period of time, take the batteries out regardless of the type. Even if they aren't prone to leaking, at least you can use those batteries elsewhere in the meantime.

there is a video lag on the usb models, they are slowed down by the usb link.
there is almost no lag on the models with an integrated screen.
the $45 has a bad stand, I found the same but with the stand of the $189 one (without the leds), it's far better for some $60
then I bought the andonstar 302 model, and it's far far better crisp picture. and no lag at all.
I did not try an external hdmi monitor, but it seems there is also no lag witht hem.

The HDMI output is appealing, does it give more realtime update?
The first one does 30fps @ 1080P (no lag; it directly feeds a monitor). The second one linked only does 30fps @ 640x480, and is only over USB (which will introduce lag). That said, either could work for inspection purposes, where fps or lag isn't critical IMHO as there's no motion involved.

If you mean to work under it, keep in mind it's not intuitive as there's no depth perception as is with a stereo microscope.

FWIW, there's currently a Nikon SMZ-1 Stereo Zoom Microscope (https://www.ebay.co.uk/itm/Nikon-SMZ-1-stereo-zoom-microscope-pod/323076993912?hash=item4b38e3b378:g:coQAAOSwkvFacItK) listed on eBay for 99GBP (+ 35GBP shipping). It's lenses will give 7x - 30x magnification. Add a 0.5x Barlow (https://www.ebay.co.uk/itm/Nikon-SMZ-1-stereo-zoom-microscope-pod/323076993912?hash=item4b38e3b378:g:coQAAOSwkvFacItK) (14.50GBP shipped), and you're right where you'd want to be for soldering beneath it. Worst case, you might need to unscrew the Barlow for inspection if 15x isn't enough. The working height is 181mm with 0.5x Barlow (found a 4pg. instruction guide).

It needs a stand, but it's one heck of a deal from what I can tell. Example (http://www.ebay.co.uk/itm/76-85mm-Ring-25mm-Heavy-Duty-Microscope-Head-Arm-Boom-Support-Stereo-Table-Stand/311586631978?hash=item488c02b12a:m:m8lKuLE9Ewby30xlByo-ecg).

You could also elect to go for another version of the $45 model mentioned in the video and as also reviewed by Defpom, the version as sold here https://www.aliexpress.com/item/Portable-600X-3-6MP-Digital-Microscope-4-3-LCD-Electronic-HD-Video-Microscopes-USB-Endoscope-Magnifier/32828884857.html?spm=a2g0s.9042311.0.0.nN4XqI (https://www.aliexpress.com/item/Portable-600X-3-6MP-Digital-Microscope-4-3-LCD-Electronic-HD-Video-Microscopes-USB-Endoscope-Magnifier/32828884857.html?spm=a2g0s.9042311.0.0.nN4XqI)

I have the little Addonstar USB model as per first link on this page and also the one from Aliexpress, both have their good points but overall the more expensive of the two is by far the best. The weakest link on them both is the built in lighting, being so close to the lens, you get a lot glare and reflections on the screen.

On the video, he does not mention that the $45 one can be used on the computer via the USB lead if you have the required software as it is not supplied with it for some strange reason?

I use it with the software supplied by Addonstar for the USB microscope and its not too bad really and there is very little lag, certainly not enough to worry about.  I have sourced a ring light to fit the Aliexpress and the it will fit the $45 one as well, you'll need to find longer screws to grip the scope or use a couple of layers of insulting tape around the barrel of the lens to enable the screws to bite like this one here https://www.ebay.co.uk/itm/60LED-Adjustable-Ring-Light-Illuminator-Lamp-for-Stereo-Zoom-Microscope/282715024608?hash=item41d320ece0:m:mtDwubI8WZBsgNZvmzrw1og (https://www.ebay.co.uk/itm/60LED-Adjustable-Ring-Light-Illuminator-Lamp-for-Stereo-Zoom-Microscope/282715024608?hash=item41d320ece0:m:mtDwubI8WZBsgNZvmzrw1og) the screws are longer then the others I have seen and will just about clamp onto the body of the scope.

Now how long should I procrastinate before hitting BUY.
Title: Re: What did you buy today? Post your latest purchase!
Post by: ChrisLX200 on February 25, 2018, 09:44:56 am
I can recommend the Adonstar 302 for its 8" of working clearance beneath the lens. Image quality is good and yes, HDMI output is available. Latency is low so quite usable for manipulating small objects and soldering of course.

Yesterday I received an additional LED ring light which I'll fit (based on Specmaster's review of the thing - it produces excellent even/flat illumination). Can be bought cheaply off Ebay etc.

Paulca, I'd second good lighting.  :-+

FWIW, I've a ring light as well as from both sides (helps identifying IC's when hitting it with light at an angle IME). I use 5000K (12 o'clock/noon) lighting to be the best as it doesn't have a blueish shade to it. Nor is it on the yellowish side as is the case with warmer light, such as that from a halogen on the order of 2700K or so.

Yet another used precision shunt resistor, after prev. batch (here (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/msg1428327/#msg1428327)), got tempted again  :palm:, cause this time its M4 version, with nickel plated solid brass rod terminals for the Kelvin sensing connections instead of finicky wires like prev ones. Got these just the fractions of the list price, a brand new one is >$200 a pop.  :o

As with resistance at 0.01 Ohm with following specifications :
- Accuracy : 0.1% (B grade)
- Tempco : 50 ppm/K (at 0 up to 100 C)
- Rating : 50 Watt with heat sink / 20 Watt on free air

I'm installing an IEC 320 power inlet connector in place of a formerly fixed AC mains cable on a piece of gear, and since my 30+ year old POS Rat Shack nibbler is nowhere to be found I decided to bite the bullet and buy some real nibblers.  Brown Santa just dropped these two off, courtesy of Amazon:

I still have an Adeltool nibbler that would be about 40 years old. Still works perfectly. It is exactly the same as the one you bought. As well as metal, they are fabulous at nibbling away at PCB material. Very clean cut with very little deformation.  :-+

I don't doubt it - the one I'd used at my previous job looked old at the time, and that was 20 years ago now.

    Just made my first purchase on Ebay for a while now, its been a bit chaotic since Christmas.

    ..did you get the carrying case it has to be stored and transported in with it..?  >:D
    Nice young timer DMM. Is it a Schlumber solarton brand?
    You will clean it up, will you?  :)
    I'll do my very best to clean it up of course, I can't stand having equipment defaced with scribble all over it. I'm hoping that it will clean up OK, the labels won't be a problem at all.
    The most important part for me is the fascia as the meter will be part of a stack so if the case doesn't come up as clean as I'd like, it won't be that much of a problem. 

    Yes it is a Schlumber solarton meter, never had one of these before so I thought I ought to try one, not too many around these days.

    The term Copper is the common usage name in Australia at least. Named after the normal Copper liner. Outsides of Brick Cast Iron or Concrete were common with a fire box under them in a lot of cases. Still in use in the early 60's. These days I have several liners with pot plants in them and one cast Iron outer as a stand.

    Tektronix TLA5202, "for parts or not working; screen flashes on boot, external monitor works.".... $150.

    Fix: Change bios primary boot device from AGP (external video card) to PCI (internal LCD).

    Yay.

    *EDIT*: This appears to have the 2M memory option... now time to disassemble, back up the factory drive, and then see what fun I can have with this. The unit itself has one damaged BNC connector on the front ("External signal out"); it appears functional, just looks like someone bent part of the outer ring and then snipped the bent part off with shears so they could fit a BNC on it again. Hoping this will help me troubleshoot the Valhalla 2701C I've been working on. :)... although I'm going to have a hard time resisting trying to upgrade this 5202 first.

    ... 120GB SSD, 4GB of memory ordered for this, replaced the CMOS battery which was flatter than a pancake. Unit appears to be in very good shape; some of the torx were tight enough that I wonder if it's ever been opened. BIOS log suggests it was used from 04 through 08, once in 2012, and then idle/flat battery. Wonder if the thing got tossed to the side because the CMOS battery went dead and the BIOS defaults to AGP output instead of the internal PCI/LCD screen!

    *EDIT2*: This was too easy... So, I'm currently reformatting the factory drive, without a backup, and installing windowsXP to try to get the latest TLA software on this one. Wheeee.

    I just spent $80 on digikey.  :o

    23 dollars of capacitors for the HP 3456A, expensive 10,000 hour types. Some rated at 105c.
    23 dollars of capacitors for the Fluke 8300A, expensive because the design dictates axial. Anything else won't fit.
     5 dollars of capacitors for miscellaneous reasons.
     7 dollars of logic chips for a project
     6 dollar c-14 receptacle for an experiment
    12 dollar test lead set
    and the banana plug receptacles needed to retrofit my Hickoks.

    Also a power supply board from ebay to try and fix my tv, oh how the money flies..... ::)

    Electronics inside are actually an N9923A. It is an extreme mod but it was done by Agilent engineers many years ago, it is a one off that escaped from the Agilent tombs. And it is far from finished with respect to hardware and software.

    Yes that's the one that sees most use, it really is a brilliant tool. Be careful with lead free solder as it tends to form small beads of solder and unless you hold the trigger on and suck air as you remove the gun from the joint, it can block the nozzle.

    A stack of silicone cable, among other things, from the HobbyKing warehouse sale. Some of it at ridiculous prices and free shipping over $50 here in Aus
    Was 3m for $11 a good deal ? Didnt think so, so skipped when my friends were ordering RC parts.

    Turnigy High Quality 10AWG Silicone Wire 9m (Black) for $3.02
    Turnigy High Quality 20AWG Silicone Wire 15m (Black)  150000148-0   A$0.79

    I happened to be on the HK website looking for wire, of all things, when the sale started (a few hours before it was announced) and there seemed to be quite a few anomalies in pricing (way too low). My order(s) are on the way now as order fulfilled.. then there was this...

    Big Power Mini Metal 8 In 1 Kit (W/O Power Supply)  672000001-0   A$29.02
    https://hobbyking.com/en_us/big-power-mini-metal-8-in-1-kit-w-o-power-supply.html (https://hobbyking.com/en_us/big-power-mini-metal-8-in-1-kit-w-o-power-supply.html)  ;D

    Which I couldn't walk away from. As usual with HK it's all a bit hit and miss, especially when the world catches on that there's a sale and the website goes into limp mode.

    Take good care about a unique peace of equipment like this. I'd be happy to give sanctuary to lone soles like these one-offs.  ;D

    I'll do my best - it is a delicate beast. The back cover is unusual and wants to crack from just a dirty look. It is like the plastic has rapidly aged.

    Bought two HP 8640 signal generators. Don't really need them but they are boatanchors, they have a cavity resonator not a rubbis digital PLL, and I've read good things about them (good sine purity and level goes down to -145dbm)

    Fuse was blown. Now gets power bit no display. Should be a fun project. Typo in the photos, its the 8500A, not the 8005A....haha
    I just finished doing a hardware cal on my Fluke 8505.  Lots of interactive pots to adjust.  Particularly in the A/D linearity adjustment.  Final result was pretty good however.   Just takes time, patience and adjusting the procedures to fit the cal equipment you have on hand.

    Pile of these PCN Corp. precision shunt resistors that I gathered thru 3 separate purchases recently -> (1st (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/msg1428327/#msg1428327)) (2nd (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/msg1436254/#msg1436254)).
    Definitely can't afford these if they are new, as this pile alone (7 resistors) may cost > US$ 1000. (List Price (http://www.pcn.co.jp/eshop/product04.htm#RHF250M4))  :o

    The latest 3rd batch purchase of this used PCN resistor, hopefully this is the last, as I kept telling my self to restraint, yet, I failed caused by a damn single "Q" character suffix printed at the resistor.  :palm:

    - Resistance : 0.01 Ohm
    - Accuracy : 0.02% ("Q" Grade) -> (Datasheet (http://www.pcn.co.jp/PCN_PDF_E/e-pcrh.pdf))
    - Tempco : 50 ppm/K (at 0 up to 100 C)

    I bought a 2nd hand IR thermometer today on Ebay. Looks decent enough condition and spec etc but i'll have to wait a few days till it gets delivered before I can be sure. I've been looking to get 1 for a while now but just never got round to it.

    I was leaning towards 1 of the Fluke 62 MAX ones that get a good write up but I saw this 1 and liked the look of it so took a punt on it. We'll see soon enough if I was right to take the chance or if I should have stuck with a good old Fluke branded 1.  :)

    The one I ordered is Model No--EBRO TFI 550.

    I brought mine from Lidls for around £9 I think and although I don't use it much, it has been very good at locating overheating components due to short circuits etc. Well worth getting and unlike a thermal camera, the laser dot pinpoints the problem item visually for you.

    ... yesterday I bought a 465B.   :-DD

    Now I should probably sell my two 468's and the 465 that I'm almost done restoring (pending a few out of tolerance resistors in the vert amp circuit that I missed on my first parts order..). 

    I think I have an addiction... and lack restraint.

    All the stuff I ordered last month for my new CNC machine are starting to arrive from all over the world.
    The cables are special series from Lapp and Igus, designed for use in energy chains, able to survive over 5 million bends.
    In the end all components will have been sent from 10 different countries from three continents, quite a change from how we did things 15 years ago  8)

    My " Duble USB Output Power Adapter 12V To 5V 3A 15W DC DC Converter Module Connector " arrived today to give me a permanent USB feed from my power chair. It really was spelt "Duble" in the advert  :-DD
    I use a XLR plug into a car fag lighter USB port just now which works fine. It's a "Dubel" too! :) Powers my laptop or puffer or extra lights if I need them. Handy as hell!
    I want a more permanent fitting though so this should do the job...."should"!  8)

    My " Fluke 80BK-A Type-K thermocouple " also arrived this morning. I thought it would be a real crap cheapy job as it only cost 8 quid! It matches my EX505 to the exact number. The temperature is the only reading that is accurate on my EX505! I won't need it for anything scientific so as long as it's near enough it'll do me  :)

    Happy days!  :D

    It is going to be a portal mill with 0.95 meters by 0.6 meters workspace (total framesize 1.2 x 0.95 meters).
    The design has been made as opensource design by cnczone.nl and it uses quality parts like Hiwin guided rails and carriages, Isel spindles etc. Total cost of all the parts is around 6500 euros  :o
    It is designed for woodmilling but this design is sturdy enough to mill aluminium , iron can be done also but then care has to be taken about speed and feed, it is not actually designed for steel.
    I have a cheap german made cnc mill but it is just toy compared to this thing although it also costs 3500 but that is incl labor, profit etc.

    This is seriously making me sad and angry at the same time.

    What you witness here is the cluster f*ck of three EMG TR-0463 function generators that I bought from the small ads a couple of days ago. That is exactly how they were packaged and delivered to me - I just cut open the box.

    WTF? How? Why?

    Need to do some proper inspection, but already found some smashed knobs and stuff.

    I can sympathise with your suffering, I bought a bench meter from an interstate Ebay seller last year and specifically asked during our correspondence if he could pack the meter properly, the moron went mad with the bubble wrap but then went completely nuts with tightly wrapped packing tape thus defeating the cushioning effect of the bubble wrap. It was then placed in a post pack which is just a plastic bag with an address label and the thing arrived all smashed up on the corners, some people really are dick heads.

    Hi,

    I think I got a 'shockingly' good deal at a local antique market:

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=401123;image)

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=401125;image)

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=401129;image)

    I estimate that the machine was made between 1854 and 1864.
    Not bad since Faraday discovered induction in 1831.

    The instruction read:

    "Connect two metallic cords or wires with the sockets in the ends of the Box, and apply handles connected with the other ends of the metallic cords or wires to any part of the person through which is desirable to pass the current of Electricity. Then turn the crank, regulating the strength of the current by the speed, and by the knob at the end of the box : it being desirable to increase the strength to that degree most agreeable to the patient. It is less unpleasant to the patient if wet sponges are placed in the ends of the handles and these applied to the skin, as they prevent the prickling sensation. The sponges should never be put inside the Box while wet as they rust the machinery. In applying it for the Toothache, Tic-Doloreaux or Neuralgia, the operator takes one Handle and places fingers or sponge over the part affected, while the patient hold the other Handle. In applying it to the foot place one of the Handles in the Water with the foot, and hold the other in the hand, or apply it to any other part of the person. The Bearings and Spring must be oiled occasionally".


    I have been unable test it because the drive belt needs to be replaced.
    The labels indicates that it was distributed by Harvey, Reynolds and Co. 10 Briggate, Leeds.
    Harvey, Reynolds and Co. became Reynolds an Branson, a supplier to many school science laboratories until they closed in 1972. Probably familiar to some UK members.

    From the company history:

    https://en.wikipedia.org/wiki/Reynolds_and_Branson (https://en.wikipedia.org/wiki/Reynolds_and_Branson)


    I visited Reynolds & Branson when I was about 10 or 11 years old.

    Here is a link to one on YouTube (not mine):

    That's getting close to what ready made or built solutions would cost. Is there any particular reason to go for this option?
    A machine with these exact parts and specifications complete ready built by a commercial company would sell probably for around 12k€ easy (cheap labour).
    The assembly work alone including the electronics cabinet is two manweeks, the parts are also 6,5k€ include profit and shipping and you are probably close to the 15k€.

    Yes there are ready build machines costing 6k€ , I myself purchased a 4k€ machine ten years ago but those are in comparison a totally different category.
    They are not as rigid, they don't have closed loop steppers, no vfd spindle, no professional controls, no hardend german quality iron spindles/ballbearings with precision machining and no high quality linear guides. If you test them on accuracy and repeatability you are in a different league.
    In short they are skimping on every part. It might look the same for a layman but it sure is not the same  ;)

    So if you want a short overview of where the costs are coming from:

    Aluminium profiles:                                           €700
    Machined and anodised aluminium parts:          €1000
    Hiwin guiderails and blocks for X,Y,Z axis:          €800
    Isel axis 2x X ,Y,Z  + ballscrew mounts            €1000
    Small mechanical parts t-nuts, bolts                  €100
    Closed loop steppers and drivers 4 sets             €750
    Motor couplings holders                                     €50
    Bearings for the axis                                        €150
    Electronic parts, powersupplies etc                    €400
    Motor cables energy chains                               €250
    Rittal metal enclosure 60x40cm                         €100
    CNC software and IP controller board EdingCNC  €400
    Iron table stand custom welded                        €250
    T bar aluminium plate 800x600mm                   €420
    1,5kW Spindle + VFD                                       €300   +
                                                                  ----------------
                                                                          6600.-

    Now I could have saved €500 by machining the aluminium parts my self, but for the rest I would not know where to get lower prices for the same quality.
    Some non critical parts like the stepper motors are already low cost Leadshine drivers. The 1,5kW spindle is also Chinese since a German quality one costs over €2000.- upto €4500.-
    So it is actually also for some parts cheap, I will upgrade later on, for the mechanical part that has to be 100% from the start, but for instance the spindle can be upgraded later on.

    That really sucks!! Someone recently did the same to me with a Tek 475A...  I should have known better than to buy from a pawn shop xBay seller... I specifically asked for extra packing foam in the front and rear of the scope, so what does he do???  He folds down the handle and STUFFS a bunch of packing PAPER between the instrument controls and the handle, drops it in a box, and loosely fills it with packing peanuts.... that's definitely not the first and wont be the last time I see a horrid packing job.

    I've often wondered how many head-scratchers we would see if a thread along the lines of "Horrid packaging jobs - let's see 'em!" were to be started..

    A machine with these exact parts and specifications complete ready built by a commercial company would sell probably for around 12k€ easy (cheap labour).
    The assembly work alone including the electronics cabinet is two manweeks, the parts are also 6,5k€ include profit and shipping and you are probably close to the 15k€.

    Yes there are ready build machines costing 6k€ , I myself purchased a 4k€ machine ten years ago but those are in comparison a totally different category.
    They are not as rigid, they don't have closed loop steppers, no vfd spindle, no professional controls, no hardend german quality iron spindles/ballbearings with precision machining and no high quality linear guides. If you test them on accuracy and repeatability you are in a different league.
    In short they are skimping on every part. It might look the same for a layman but it sure is not the same  ;)

    So if you want a short overview of where the costs are coming from:

    Aluminium profiles:                                           €700
    Machined and anodised aluminium parts:          €1000
    Hiwin guiderails and blocks for X,Y,Z axis:          €800
    Isel axis 2x X ,Y,Z  + ballscrew mounts            €1000
    Small mechanical parts t-nuts, bolts                  €100
    Closed loop steppers and drivers 4 sets             €750
    Motor couplings holders                                     €50
    Bearings for the axis                                        €150
    Electronic parts, powersupplies etc                    €400
    Motor cables energy chains                               €250
    Rittal metal enclosure 60x40cm                         €100
    CNC software and IP controller board EdingCNC  €400
    Iron table stand custom welded                        €250
    T bar aluminium plate 800x600mm                   €420
    1,5kW Spindle + VFD                                       €300   +
                                                                  ----------------
                                                                          6600.-

    Now I could have saved €500 by machining the aluminium parts my self, but for the rest I would not know where to get lower prices for the same quality.
    Some non critical parts like the stepper motors are already low cost Leadshine drivers. The 1,5kW spindle is also Chinese since a German quality one costs over €2000.- upto €4500.-
    So it is actually also for some parts cheap, I will upgrade later on, for the mechanical part that has to be 100% from the start, but for instance the spindle can be upgraded later on.
    Closed loop steppers are servos, right?

    Do you have a link to any plans or examples? This all sounds fairly interesting.

    Yes but historically they preserved the name servo for high voltage AC motors if I am not mistaken, but yes they are 3 phase stepper motors with an 1000ppr encoder built in for the feedback loop.

    I recently bought a defective HP 6114A. Nice repair game awaited.   ;)

    Also bought an HP 8484A power sensor 100pW -10µW for 105€ incl. shipping. Auction time was only two days and the subject had misspellings in it -I hope I had luck and was the only one who accidentally stepped over it (I placed the only (minimum) bid).
    I already have an 8484A power sensor I got for a good price -but it's the older model that "only" goes down to 300pW.   :palm:   :-DD

    I'm curious if it's intact and working properly -if not I'll go for refund because the seller sold it as "used but fully functional" and claimed he's not taking it back..  >:D

    Oh, I bought a BILLY bookcase together with two OXBERG panel/glass doors from that Swedish company selling funnily named furniture.    ;)

    The lower half will be storage room and the upper half showcase for a part of my safety/railway signalling relay collection (yes, there's another addiction  :palm:)
    Moving my relay collection gives me room in my desk drawers of my bench that I need urgently -I'm rearranging my bench currently because it was built to weak to house all my Test Equipment and also because I was running out of space.
    This solution has my wife's acceptance.   :-+ :-+   :popcorn:

    Better safe than sorry.

    I got a new main filter and a bunch of pre filters for my "new" bargain metcal solder fume extractor...

    I figured having an extractor with the filter either backwards, or flipped the right way after being run backwards for some unknown amount of time is kind of missing the point of having a device that sucks fumes out of the air.. and while it certainly bumps up the price of my bargain, I know that
    1) it's working right for sure
    2) the age of the filters in it.

    We had to dump the set we had at work in the '90s (Read: divert to a worthy cause - me) as they were not compliant with the electrical standards here in Queensland, not sure about the rest of Australia.

    These are very useful devices for quick testing, I use mine at least once a week, are you keeping the British 13A fuse in yours? Mines been 'hacked' to take a standard 3AG fuse.

    Only just ordered. Most likely drop the fuse to either 3 or 5A. Anything more serious is worthy of a covered screw block. Compliance wise I reckon these are fairly idiot proof unless you poke screwdrivers inside it with the lid up  :-/O

    Cheap RF power meter board.   $22 including shipping.  Checked it out using the spectrum analyzer and within 0.5dB.   At first I thought it was reading slightly high but then I realized it was also adding up the harmonics from the source.  I added a low-pass filter and now the SA and Power meter agree within 0.5dB.   This model only goes up to 600Mhz but I have another model on order for the higher frequencies.   Not bad for the $$.   I 3D printed the white plastic to give the bare board some protection.   

    Specs:  0.1 to 600MHz, -75 to +16dBm.  Provision to add external attenuation to the readout.  A calibration feature I have not yet tried.  Powered by +6-12 VDC.

    I've often wondered how many head-scratchers we would see if a thread along the lines of "Horrid packaging jobs - let's see 'em!" were to be started..


    That's a good idea. I've received a few packaging fails too. Some people seem to be just incredibly incompetent, or totally slack. It's very unfortunate when a 'packing challenged scum' sends some rare, delicate, heavy and expensive gear through the post.

    A thread of examples could be quite useful. Name names, shame the bastards. After a while the thread could be quite useful for looking up sellers to see if they are mentioned. Also to direct sellers to, if you think they are possibly 'packing naive', so they can see what happens when they don't do it right. Could also post pics of particularly good packing as demonstrations of how to do it right.

    frozenfrogz , would you like to start a new thread? Since you are the one currently hurting.

    I can add a few. For eg: http://everist.org/NobLog/20160429_first_of_the_last.htm (http://everist.org/NobLog/20160429_first_of_the_last.htm) and http://everist.org/NobLog/20130215_The_Q_meter.htm (http://everist.org/NobLog/20130215_The_Q_meter.htm)

    What would be a good title for a perma-thread? Something expressive, but which isn't insulting to a seller sent to read it.
    Packing failures and successes - Lessons learnt  maybe. Suggestions?

    Cool, I pulled mine apart to see if there was an easy way to get more rpm out of the fan, unfortunately it's a basic 240 vac motor with just an on off switch so I might see if I can find a higher cfm fan and retro fit it to boost performance.

    Went to buy C, bought D,E,F,G.
    A few tools, from an old machinist clearing out his garage on gumtree. Dammit, I could have spent ten times what I did, if I had it to spare.

    All the cutting bits are tapered drills. Not something I _really_ need, just cool. And would be pretty hard to buy if I ever do need some.
    Mainly I wanted the proper machinist's vice, and ratcheting thick cable cutter. The sheet of gasket material was thrown in free.
    The reel is hardened fine stainless steel wire, used for wire cutting (like water jet cutting.) Not that I have a wire cutting machine, but I'm pretty sure that will be useful.
    The bags of crimp terminals are some special silver-nickel alloy, that's good up to around 400 deg C.

    $190 all up. What I went there for, was a 3-jaw lathe chuck. He didn't have a suitable one.

    Edit: Yes, I already cleaned the surface rust off the vice.

    The companies that maintained the machines usually scrapped the PCBs after the game was no longer popular or too old to be interesting. I did some work for one of these companies and they had an entire hall full of these boards stacked head-high. I think I still have some of them that I took for parts (mainly for the EPROMs as they sometimes contained 20+ socketed EPROMs).

    McBryce.

    Edit: Forgot to mention: I just scored a "defect" Flir One V2 for Android. Description said "it sometimes works" and the owner thinks that wobbling the USB connector gave results. Are/were these known to have dodgy joints around that area? Is there anything else I should be looking for? Either way, I got it for absolute peanuts, so even if I don't get it working, I won't be all that worried.

    Solder wire 62/36/2 Tin/Lead/Ag ISO 29454 1.1.1 rosin-fluxed, roughly 0.4mm
    Pomona croc clip breakout.
    Filter for 60mm fan for 66311B and while I'm at is for my PC, printer and switch
    Enamel wire in various sizes which took me ages to work out with the weird American units.

    Doubt I'll be using Digikey again in a hurry.

    Cool hope it works out. Where did you get these vintage boards? I know a lot of arcade machines were stripped for the parts or rebuild the cabinet for mame clones. I just don't know where the parts ended up.
    At vast expense on EBAY.  They are collectable up until the point they are not-repairable due to lack of custom parts.  Some custom chips have modern CPLD replacements but most are unobtainium.

    What I went there for, was a 3-jaw lathe chuck. He didn't have a suitable one.

    Have you seen the chucks Hare & Forbes sell. Quality seems reasonable for the price.

    Yep! I've bought enough from them that I get their catalog in the mail. They have a sale on Thur 15th - Sat 17th of March btw.

    But I'm looking for a 3-jaw that fits my recently bought big OLD Macson lathe. Has an unusual chuck mounting. The 3-jaw that came with it has a crack in one of the jaws. I can make an adapter to some other chuck, but haven't really seriously started looking for an original replacement yet. Just happened to see a gumtree listing, and the guy was nearby.

    I'm making a magnetic/flexible build-plate for my 3D printer so I bought some thin spring steel sheet (0.8mm) and will use some neomydium magnets embedded in the alloy heated bed platform. Problem was - what to use to glue the magnets in place? After searching around I bought the stuff shown below: Permatex Supra Grey. Good for 260degC so certainly suitable for 110degC (max) of the heated bed.

    Also received some 2ft lengths of Nylon rod (6mm and 8mm dia) to make a remote push-switch for my PSU.

    Nice!

    I had an Atari Portfolio back in the day (as used in T2), it was fantastic for getting past STD/ISD dial lockout's on the dumb PABX's most companies had in the 90's as it had a built in tone-dialer. This let you bypass systems that limited the length of the phone number you could dial. I also used to write code on it in the text editor for assignments when I was bored at work (computer and Hifi sales).

    a Desoldering gun. (plus more anti-static matting, some contact cleaning spray, freeze spray, etc etc... damn you Mektronics!)

    I really wanted a Metcal/Thermaltronics unit to go with my soldering station, because the idea of owning an air powered tool was exciting. But sensibleness prevailed and I bought something that doesn't need a compressor under my desk, and can work independently of my main soldering iron.

    So I got the Den-on SC7000Z and the matching stand.

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=402227;image)

    Initial thoughts:

    The stand kind of sucks. the handle of the gun rests on the table, and it sits really untidily, with the power cable not easy to tuck out of the way... And the heated metal parts are clear enough of the desk if you just rest the gun on its side anyway... I probably wouldn't have spent the extra $50 on it if I'd seen it in action.

    The gun is pretty hefty, but seems quite well balanced. I reckon I could do a lot of desoldering with this if I needed to.

    Can't you just give the stand a bend backwards to get the gun to clear the desk?

    the strip of metal where the iron holder connects to the base is relatively thin.
    I expect that if I bent it up it'd end up back down on the bench soon enough.

    But still, I guess I'll try it, if I don't decide to just return it.
    At the moment it's returnable in as-supplied condition with box and plastic. And the gun could do with a second tip with a bigger opening. (comes supplied with just a 1.0mm opening tip)

    Very happy with the actual SC7000Z itself though (which is the main thing)  - I had a quick go desoldering a few TH parts this afternoon. It made pretty short work of some heavy looking solder joints

    Congrats!

    I bought one of the cheapo 24V/80W clones some time ago and do not know how I could live without one for such long time :)

    A desoldering gun is such an essential time and trouble saver!

    I had the same but one more flagship, the Sharp PC1600 with floppy-drive and 4 color A4 size Plotter
    It also had RS232 at the time and I had interfaced it to instruments.
    But that was real $$$ at the time.

    It is a nice soldering station but one of the 2 units had its heating element burned out after short usage for no reason... I have to replace it now. Do you know where I can buy one? I got the whole station for 18$ on discount!

    Well I might have some good news for you, if you are not afraid of splicing. It is of course a generic element, but that specific type is common as dirt in china.  It is the, "A1322 Heating Element", i am guessing based off the handle. No guarantees of course, i may be wrong, but i had a handle very similar.

    Personally, I'd spend a fraction more and get some 220 in 24 out T12 soldering units, spares are really plentiful and cheap. They are the best soldering experience I've ever had, really fast heat up time and fully controllable Banggood and Aliexpress  sell them.

    After a few years of reliable power delivery and ease of use, I went ahead for my second Korad KA3005P unit.

    I guess the lesson learned is to either buy two of these or get a triple-output PS. Even though I have two other low-range power supplies, I kept myself finding the need for a second lab-graded PS during some experiments.

    Ever ordered something and completely forgotten about it? This DPS5015 arrived today which I'd ordered just before Chinese New Year..

    Also thirty 608 bearings to go into stock - less 8 to be used to make a couple of 3D Printer filament rollers (the base is the red thing to the right). That's printed with PET-G, good stuff to print with albeit it's a bit stringy requiring some clean up. A little more flexible than ABS but much tougher and less likely to crack/snap. Another big advantage - it doesn't warp like ABS!

    Regarding stringing while printing PETG:

    I found, that PETG can be printed nicely at lower temperatures than specified. Depending on the part and how quick I am printing, I usually go for 205°C as a starting point. Gives me very nice results, even with high extrusion rates on the UMO+.
    IPETG from dasfilament.de that is - can not say a lot about other manufacturers.

    That's interesting, and worth an experiment. I start the first layer @ 240 then drop to 230 for the remainder. I've tried with/without the nozzle cooler enabled too and the stringing is worse with the cooler on, although the result is much more 'blobby' without (which is actually more difficult to clean up). A quick exposure to a cigarette light flame quickly removes the fine strings but does nothing for the blobs which need to be manually cut off.

    Well I might have some good news for you, if you are not afraid of splicing. It is of course a generic element, but that specific type is common as dirt in china.  It is the, "A1322 Heating Element", i am guessing based off the handle. No guarantees of course, i may be wrong, but i had a handle very similar.

    Is this the one: https://www.banggood.com/5pcs-24V-50W-A1322-Soldering-Station-Replacement-Heating-Element-Ceramic-Heater-p-1094025.html (https://www.banggood.com/5pcs-24V-50W-A1322-Soldering-Station-Replacement-Heating-Element-Ceramic-Heater-p-1094025.html) ??

    and Banggood has this:

    https://www.banggood.com/110V220V-Heating-Element-for-YIHUA-908-Electric-Iron-Thermostat-Soldering-Station-p-1117931.html (https://www.banggood.com/110V220V-Heating-Element-for-YIHUA-908-Electric-Iron-Thermostat-Soldering-Station-p-1117931.html)

    Personally, I'd spend a fraction more and get some 220 in 24 out T12 soldering units, spares are really plentiful and cheap. They are the best soldering experience I've ever had, really fast heat up time and fully controllable Banggood and Aliexpress  sell them.

    My luck was bad on the one that stopped working, because I am using the other one and it is perfect. I liked it because of small size and so on.. will get others too in the future.

    This is the one you mean: https://www.banggood.com/DSK-Digital-Soldering-Station-Kit-Soldering-Iron-Station-Temperature-Controller-p-1055574.html (https://www.banggood.com/DSK-Digital-Soldering-Station-Kit-Soldering-Iron-Station-Temperature-Controller-p-1055574.html)

    it is 50$ without the base so it is not as you explained, I expect the whole one to be 60$ at least. Cannot compete 18$.

    this one was my first choice: https://www.banggood.com/110V-220V-Inverter-Frequency-Change-Electric-936-Power-Soldering-Station-Iron-p-1093556.html[/url
     (https://www.banggood.com/110V-220V-Inverter-Frequency-Change-Electric-936-Power-Soldering-Station-Iron-p-1093556.html)

    Either should work, give or take some improvisation.

    I would wait till I had the iron and can take a look at the element. It is probably either the A1321 or A1322 but they are different. The temperature elements has different resistances. The A1321 is almost 50 ohms and the A1322 is something like 12 ohms. The wire length for the power and sense leads are different to the extent that you couldn't out a A1321 element in a A1322 iron or visa-versa without extending wires.

    Well, it was technically purchased on Friday, but it arrived today.  I believe I saw this on someone's bench picture on the 'Show us your workbench' thread about a month ago, and, being tired of hanging my pliers on the edge of a cardboard box on top of my wire equipment rack, decided to buy one.  I think it will make for much neater tool storage:

    A few weeks ago I bought an STM32f746g-disco development board.
     If you add on a small daughter board with a small synthesiser (SI5351A) along with two mixer IC (SA612), using the board layout and software very Kindly shared freely by EU1KY;  for a total of about AUD$110 you can make a 450MHz  S11 Antenna VNA! As Dave would say BEAUDY MATE  :-+
    It can measure R + j
                           Time Domain Reflectometry
                           Scan a reasonable span ie multiple 10s of MHz
                           Calculate a solution for 50 Ohm system
                           Act as a weak 2-20mV signal generator

    But I had to take it apart to find the pinout of the connector, I can't read chinese colors.

    To my surprise, I did not expect it to work with a magnet.

    There is a magnet bond to the shaft, when the shaft rotates, the magnetic field commutates, and the sensor IC detects the position by the H field.

    Yes, I deduced all that from the photo.  Which is why I asked about external fields. Presumably the housing is steel or mu-metal and provides some magnetic shielding. But it can't be 100%.

    Mine was 6 days ago but it should have been today when a heap of new stock arrived.
    I joined the 20+ scopes club  :) well just for a few days.........  :(

    Happy birthday, djos and tautech.

    Tautech, you should take a pic with those 20+ scopes to keep for posterity. ;D

    Thanks bitseeker but they're going out the door that fast it's doing my head in.  :scared:
    Somewhere in this thread there's a pic I posted of a dozen or so destined for a classroom set.
    Next order that'll be bigger still might be worth taking a snap of, but they're pretty boring all in boxes.  ::)

    All sounds like great fun but the gloss wears off when you need to unbox every one, ensure it boots, check and maybe update FW version, then Self Cal and check probes, compensate, assign to channel (fit color rings) and check 10x, 1x switch.
    Yep all this latest lot need all that ^  each !!
    More than four at a time is just tooooooo hard !

    Gotta shoot off soon to deliver some and collect a demo unit.........

    Yep, they look good, including the batteries. Nice catch.

    One of my pending projects is to make a replacement quick-connect card since my 228 didn't come with one. I've located just about everything I need except the cable retainer clamp that they use.

    Alternatively, I was thinking about potentially extended the PCB a bit and put either a Phoenix connector or banana jacks, instead of the screw terminals.

    Wait, what? So, if there's some external magnetic field, the angle data this thing gives will be wrong?
    And how linear is it?
    We can make digital compass chips, so why not use those with a magnet hovering directly above?
    I don't know about the linearity, I should check this. Any idea how?

    It would be way cheaper to get 5" floppy drive and scrap it for stepper motor and a schmitt trigger and you have the best encoder (expept optical ones but they cost an arm). Main problem is finding 5" floppy drives....

    Have you seen what a 5.25" FDD goes for these days? They start @ ~$50 + shipping.

    The 360kb drives in-particular are getting very expensive as the 1.2MB HD drives dont work too well with DD media (basically renders DSDD disks useless when put back in DD drives).

    Post by: bitseeker on March 13, 2018, 11:30:17 pm
    Yeah, HD drives are fine for reading DD disks and writing to DD disks to be read by HD drives, but not for writing to DD disks that are to be read by DD drives. Something I haven't tried is bulk erasing the disks and then writing them with an HD drive.

    One of my units is missing the PCB insert as well. I swapped it over when I did the power up test to see if the output was functional. I am going to lay one out in EasyEda tomorrow and get them ordered ASAP. Because of their size, I will get 10 of them made in a single lot, so your more than welcome to one/two.

    I don't know about the linearity, I should check this. Any idea how?

    Linearity: Hmm. It's serial data out, so you can't just look at signal edge timing like: Put a flywheel on the shaft, drive from small motor via loose belt. Check signal timing.
    Maybe: attach a long arm to the shaft, set it up with a large sheet of paper marked with the radial divisions. Or just a big protractor. Display the updating angle output, move the arm on the paper/protractor to see if the digital angle matches the actual angle, and where the resolution boundaries are.
    You'd hope it wouldn't change with orientation of the unit relative to Earth's weak magnetic field.

    The same setup to check for sensitivity to stronger external field. See whether the value boundaries (or even the direct value) change when you wave a magnet around near the unit.

    Edit: Wow, you really have to be careful with the part number.

    I think so, as is with any closing down sale, you have to see what is going in person, remember what the Woolworths closing down sale was like.

    I spoke with one of the poor salesman and he said they get deliveries almost daily, everything from the warehouse is going to be brought to the shops.

    I can feel a shopping trip coming on then. I remember when Tempo closed down, they had some good bargains on the last few days, problem is that you can get carried away and buy things that never get used, simply because it was a bargain [emoji50]

    My HP 6114 precision power supply arrived today.   :)

    I told the seller to pad the device thick and sturdy to all sides -and he did!   :-+
    The outer cardbox was damaged on one side (I could put my hand in..) but the padding and some extra cardboxes saved it from also being damaged.

    The 6114A has one flaw: It doesn't put out the voltage dialed in even though the voltage and current regulation seem to be working basically. And it has 50mV ripple on the output.
    I put it on my repair queue and will start with it right away.   :-/O

    Looks good so far, all the way down to the silkscreened lethal voltage warning. Just the remaining bottom traces and then good to go. You mentioned you're going to have them made by JLC. I've been seeing them mentioned a lot lately. Looking forward to seeing their output.

    Have you located a similar enough strain-relief clamp? I scoured Digi-Key and Mouser for a while, but didn't succeed, yet.

    Bought a couple more spools of PETG 3D printer filament, one was a standard 1Kg size (blue) the other a 2.5Kg spool (black) which offered a big saving compared to a 1Kg spool. I should have expected it but the physical size of the heavy spool took me a little by surprise! There was no way it would have been mountable on the printer had I not modified it to use external spools, the spool rollers I made sit on a shelf above the printer.

    Home made spool rollers

    One big spool of filament
    (https://farm1.staticflickr.com/789/40780319852_34f8411a01_b.jpg) (https://flic.kr/p/258BNjY)



    Edit: A cool idea I just had - one of the problems with many filaments is they are hygroscopic and need to be kept dry, they are transported in a plastic bag with dessicant inside. Of course, as soon as you take the spool out the bag it will start to deteriorate unless you take steps to prevent it (construct a dry box for example). With the spool rollers I figured I could just put the roller inside a large sealable bag, with dessicant, and the filament then pokes out through a tiny hole. It can be used this way and will stay dry. Seems to work fine!

    Yes, all links for normal operation are there.
    I must admit, I thought of a fault like that in the beginning, too.  :-/O
    But it wasn't: there are the original HP ones all in place. 

    I found the (main) fault yesterday evening after my post:
    It's a completely dead (one could think of Monty Pythons dead parrot here..  ;)) electrolytic capacitor in one of two rails for the control board A2.

    The Quick 861DE. Almost the same unit as the Quick 861DW that Rossmann and Dave tested, but with more power, 1200W vs 1000W. It also delivers 200 L/min vs 120 L/min for the DW version. And, on top of that, it's slightly cheaper. Got it for 235 pounds UK ex VAT and ex shipping from kaisertech.co.uk.

    The Quick 861DE.

    That’s the one I have been drooling over for quite some time. One day it will replace my Aoyue int906C. One day...

    I just ordered a brand new Pi 3 B+ and a case, from RS, to replace my WorkShop Pi Computer - it should be a nice upgrade from my old Model B v1.2.

    Bought a Magnum 2005 soldering station.

    Also bought an Uni-t UT61E last month.
    Both items probably won't rate that well against the more popular models, but both are a huge upgrade from what I had and I'm very happy with both.

    Will now save for a Micro soldering iron for my soldering station, hot air station and I hope to get a variable power supply as well.

    First of all I will have to buy some sort of scope. Due to Diabetes my eyesight is pretty bad. (https://uploads.tapatalk-cdn.com/20180316/ec17cbac86c3fbda71fe16a2ad2659e3.jpg)(https://uploads.tapatalk-cdn.com/20180316/446a4d018180ee04489b702963a26046.jpg)

    So, I opened up my new Quick 861DE and to my surprise it looks quite different from the 861DW that Dave reviewed. For instance, it has a different blower (since it's 200 L/min instead of 120, that's to be expected), but the main transformer isn't there, replaced by a smaller one on the main board. Also, the EMI filter on the back panel is absent. The main board says "856D-Powerdrive v2.8 2015-06-22", while the 861DW in Dave's video says "861D-MotorDrive V1.5 20150731", so the 861DW Dave had is a more recent revision than the 861DE I have.

    Now, the 856 is a different unit from Quick, you can see it here (click on 856 on one of the buttons on top):

    http://quick-global.com/2-lead-free-rework-2.html (http://quick-global.com/2-lead-free-rework-2.html)

    Checking the specs there, it seems the 861DE is a 856 in the case of the 861DW. Interesting.

    All the boards in my unit are completely different from the boards you can see in Dave's video of the 861DW. See 12:04 point in: https://www.eevblog.com/2018/02/20/eevblog-1058-quick-861dw-hot-air-rework-station-review/ (https://www.eevblog.com/2018/02/20/eevblog-1058-quick-861dw-hot-air-rework-station-review/)

    BTW, about that EMI filter missing, I didn't notice any flickering of the lights, but I don't have any fluorescents either.

    Picked up a nice and rather compact isolation transformer. The previous owner had upgraded it from 300VA to 500VA with the biggest Ring Transformer I've ever seen. My old isolation transformer only managed 200VA and was struggling in some circumstances, so it was time to upgrade. Unfortunately, like most modern Isolation transformers, the Earth wire is connected through, making it not fully isolated, but that will be modified as soon as I have time. Never heard of the maker Renesse, nor could I find anything online about the device.

    The Ring Transformer basically fills the entire case 180x180x100mm. There's probably bigger Transformers, but I don't usually deal with parts like this. I'll post a picture later.

    Don't know where did you get that WD Red, but just to say, there is a way to get WD Red cheaper, very cheap.
    You see, WD is a high tech company selling products to recover their R&D cost, with a huge profit margin, and usually their internal driver customers are either server farms or companies, and they are willing to pay the price.
    However, their external driver market is basically dominated by personal buyers, and they don't like to pay for IP.
    Therefore, WD and Seagate both sell external drives cheaper than the internal drive inside the enclosure to secure this market.

    As a result, you can buy WD Mybook or WD Easystor and strip out the internal drive.
    There are 3 possible internal drives, being WD White, WD Red 128MB and WD Red 256MB.
    You have to take a bet, the WD White is either rejected WD Red or overstock, so if you get that one, you lose the bet.
    Some WD White drives also require you to modify SATA 22P cable since they put a trap to prevent you from using the drives as internal drives.
    The WD Red 128 (AKA WD Thailand) and WD 256 (AKA WD China) are both genuine WD Red, but with TLER disabled.
    There is also a 4th possibility, HGST Helium, but that's rare, just like winning a lottery.

    Don't buy WD 2.5'' external drives, they have USB circuity on HDD PCB and no SATA exposed to external.
    Don't buy any external Seagate drives, 2.5'' or 3.5'', they use SMR drives (Seagate Archive) internally.

    I got my WD red drive from Amazon UK for £49.99, could have got a normal internal one for £35 but I did not know that the red drives will not hang if something fails to load, it will rely on the remain drives to load the data and move on. The other drives are normal internal ones and they do apparently hang in such an event and it is so annoying especially when the information is duplicated on the remaining 3 drives grr. Seriously thinking about installing 500Gb drives and going back to having just 4 separate drives instead of a raid array, then I could back them up to the 1TB plugged into a caddy on the desktop, more storage capacity and less frustration hopefully.

    I've never used these, but they're certainly interesting based on cost alone.  ;)

    Guess I should break down and buy a set as they're rather inexpensive from the pricing I've seen (currently only use a couple of solder suckers and desolder wick).

    You remove the main volume of solder from the joint using your preferred method, then you heat the joint again and push the metal tube of the tool over the pin, seperating the pin from the copper trace in the hole. It doesn't do the entire de-solder, it's just a method to free the component pin inside the hole.

    I used something like those in the old days to open up the holes on the pcbs.
    First cut off the component, heat the left wire, pull wires out.
    Now a lot of those holes would still be closed with tin.
    You heat the pad with the tin and insert the appropriate size pin, let cool down, pull out pin and done.

    Unsoldering tubes, remembering the old times when using syringe needles.
    Aha. Desoldering needles. Googling for unsoldering tubes does not provide EE soldering, but plumbing soldering.

    I have a license of Second Copy. It is a convenient and configurable package that automates regular file copies, even performs data verification. However, I use it for my Outlook mailbox + working files and, if it finds a locked or temporary file, it spins forever chasing its own tail and requiring a terminate via Task Manager. This happens even if the option to "attempt to copy files in use" is disabled. I still use it but it clearly requires some babysitting.

    I use Veeam Agent for Windows. It is free, mature and very stable. (and won't trip over an in-use file because it uses volume shadow copy)

    Single file restore through to full bare metal restore.

    At work, we have been using its big brother Veeam Backup and Replication.
    We have been using it for 6 years - Backup, replication and restore testing - flawless, it has never let us down.
    The Veeam Agent uses the same underlying technology.

    I am not associated with Veeam, just a very happy user.
    Thanks for the tip; I will give it a try.

    In the post today I received a Makita DHP 481Z brushless. Body only was around £135 delivered.
    I'm wondering if it's even worth folk putting their old drills in for service and if I should fix up my BDF451 and BHP451 as loaners / hackspace drills.

    When I've done the urgent jobs I bought it for - like fixing the shed roof that blew off - I'd sure like to get scope probes on it to see the comms between the battery and drill.

    You remove the main volume of solder from the joint using your preferred method, then you heat the joint again and push the metal tube of the tool over the pin, seperating the pin from the copper trace in the hole. It doesn't do the entire de-solder, it's just a method to free the component pin inside the hole.

    Yep. They're also handy for clearing stubborn plated through holes such as those on large traces in power supplies with tons of solder on them. Just push the solder out of the way instead of wasting lots of wick.

    I cannot see where you are referring to a 30 day trial.
    Their cloud repository support comes with a 30 day trial, but you don't need that if you are backing up to local NAS or removable drive.
    The registration is not an issue, just use a disposable email address.
    I registered using my real email address and they only send me marketing hype a couple of times a year at most.
    Entirely up to you.

    Removing the pin often isn't the hard part.  Getting rid of the solder plug in the hole is.  I used to use a dupont breadboard wire, heat the pad, push it through.  That was until I lifted pad off a board.  Got away with it as I could use another pin for the job, but... I have now moved to the heavy guns and a 1mm drill bit!  Not sure which is worse.

    I might try these solder tube needles things to see if it helps.

    I just use a powered desoldering station that sucks away the solder, so far not had any issues at all with that.

    Well I have to admit that I have not yet installed it or even read up about it, still trying to rebuilt the new drive in my NAS from the remaining 3 drives which does not seem to be going to well so I might just wipe the lot and start again.

    Some concentrated sproing.

    Thanks to don.r, for shipping me these very deadly and US-government restricted (not!) lengths of 0.002", blue tempered spring steel. That McMaster Carr had refused to ship overseas.
    So now finally I can attempt cutting some for replacing lost old-style HP button springs. I did end up with enough original HP springs, thanks to some kind donations. But there's still the mystery of how to actually make those things, for future HP gear missing the button springs.

    Once again, if anyone knows what the spring material actually used by HP was, please share. It was 0.002" thick, felt about as springy as this, did not deform when bent, but was silver-shiny color. It didn't rust. and I have a feeling this stuff will, but that remains to be seen.

    Second picture is not something I bought, but rather a paper-wasps nest that bought it. Bug sprayed at night, after I had three stings over the last couple of weeks from these guys. You just walk anywhere within a few meters of their nest, and they attack. Will follow you quite a distance. There were maybe 50 wasps sleeping on the nest, but most of them fell in long grass.

    I had to buy a 1TB drive for mr crashed NAS and I got myself a near mint AVO 1001 for a mere fraction of the hard drive cost  :popcorn:

    Don't know where did you get that WD Red, but just to say, there is a way to get WD Red cheaper, very cheap.
    You see, WD is a high tech company selling products to recover their R&D cost, with a huge profit margin, and usually their internal driver customers are either server farms or companies, and they are willing to pay the price.
    However, their external driver market is basically dominated by personal buyers, and they don't like to pay for IP.
    Therefore, WD and Seagate both sell external drives cheaper than the internal drive inside the enclosure to secure this market.

    As a result, you can buy WD Mybook or WD Easystor and strip out the internal drive.
    There are 3 possible internal drives, being WD White, WD Red 128MB and WD Red 256MB.
    You have to take a bet, the WD White is either rejected WD Red or overstock, so if you get that one, you lose the bet.
    Some WD White drives also require you to modify SATA 22P cable since they put a trap to prevent you from using the drives as internal drives.
    The WD Red 128 (AKA WD Thailand) and WD 256 (AKA WD China) are both genuine WD Red, but with TLER disabled.
    There is also a 4th possibility, HGST Helium, but that's rare, just like winning a lottery.

    Don't buy WD 2.5'' external drives, they have USB circuity on HDD PCB and no SATA exposed to external.
    Don't buy any external Seagate drives, 2.5'' or 3.5'', they use SMR drives (Seagate Archive) internally.

    I got my WD red drive from Amazon UK for £49.99, could have got a normal internal one for £35 but I did not know that the red drives will not hang if something fails to load, it will rely on the remain drives to load the data and move on. The other drives are normal internal ones and they do apparently hang in such an event and it is so annoying especially when the information is duplicated on the remaining 3 drives grr. Seriously thinking about installing 500Gb drives and going back to having just 4 separate drives instead of a raid array, then I could back them up to the 1TB plugged into a caddy on the desktop, more storage capacity and less frustration hopefully.

    If you don't have data that changes 'quickly' run the drives seperate and run snapraid. It's a snapshot parity. Then if a drive dies you can restore from parity but you also have individual drives that are still readable/removable... Then if you really need drive pooling use drivepool by snapbit.

    This is my current setup and works great I can add any size disk i want as long as my parity drive is as big or bigger. The whole thing is automated nightly via a python script called snapraid runner which will send me an email nightly on the raid status.

    I also run backblaze cloud backup to mirror all my important stuff  (pictures, home movies, etc) to cloud storage

    Picked up a nice and rather compact isolation transformer. The previous owner had upgraded it from 300VA to 500VA with the biggest Ring Transformer I've ever seen. My old isolation transformer only managed 200VA and was struggling in some circumstances, so it was time to upgrade. Unfortunately, like most modern Isolation transformers, the Earth wire is connected through, making it not fully isolated, but that will be modified as soon as I have time. Never heard of the maker Renesse, nor could I find anything online about the device.

    @Kripton2035: It took a few days, but here's what the isolation transformer looks like inside. The 9V battery is for size reference.

    Went to the scrap yard today, to drop off some old lead acid batteries. Came back with a nice box of 100A 250V SPST bistable relays, with 15V coils. Interesting in that they also have a built in current shunt, and flying leads for the coil and shunt. Waiting for them to dry out a little though.

    Yep, I'm quite happy with it. I think I primarily bought the 2.2kOhm/100W resistors and the 100 relays and the rest of the parts are bonus material.   :)   :-+

    I can/could use two different parts for my 6114A repair (https://www.eevblog.com/forum/repair/hp-6114a-repair-(fault-regulation-seems-to-work-voltage-low-output-ripple)/msg1461808/#msg1461808 (https://www.eevblog.com/forum/repair/hp-6114a-repair-(fault-regulation-seems-to-work-voltage-low-output-ripple)/msg1461808/#msg1461808)):
    First the yellow 1µF/450V~ axial foil caps, second the black EPCOS 470µF/100V~ electrolytic caps.

    Oh the classic bigclive deathadpter

    As Clive says.... Just a wee heads up that i've seen someone actually plug into one of those exact same adapters in a rush too do a job...

    Using an Aussy/NZ 3-pin mains plug and that adapter already occupying a live outlet, the plug can then be made to fit diagonally across into only 2 of the 3 adapter insert-able pin-sockets.  It's easy for the Earth pin (that connects to equipment frame) to enter the Line (Phase) 230Vac and either of the other pins onto either the Phase or Neutral. That makes the whatever equipment connected become LIVE to chassis so that could make for a large bang and all the critical smoke come out... The breaker should pop though but the damage will have happened.

    I repair TV ENG news cameras. I have seen two cameras so far powered up this way while using their clip-in adapter for Mains rather than batteries. The Mains pack destroyed and camera suffered some nasty damage, all because of these particular mains adapters.... Be doubly careful using them!

    Gave up on the idea of building my WiFi streaming audio DAC with ESP32-PICO-D4 since I don't want to waste money on FCC15C certification (it will be a product, so I better get the legal things right). Instead, I chose to use pre-certified modules to save some dollars on that, and only do an FCC15B certification (I still need to certify this thing since it has a USB port and is hence a computer peripheral).
    Hi
    I'm also interested in these ESP32 modules with the external antenna connection.
    Where did you get these from?

    It will take a particular idiot to do that. I've seen this kind of "universal" sockets being used by so many hotels, airports and flights, and I've never actually heard of an idiot forcing a type I plug into it the wrong way.

    I can't think of a single reason why a person would force a blade into a socket knowing the other one or two are floating connected to nowhere.

    And while I've never seen any adapters with finger guards, I've seen many fixed universal sockets with finger guards (except those in flight ones), and the only way you can expose the L/N holes is you plug in L and N simultaneously. Plugging into L or N alone will not allow the finger guard to open.

    That being said, I've seen a couple incidents involving this shit, including melting down, cracking and from the picture posted I can safely say this POS has no glass fiber in its plastic, and the plastic looks like it's made with a lot of recycled contents with little to no virgin plastic bead. The metal parts look like nickel plated or worse, just plain iron. The contact doesn't look like beryllium-phosphorous-copper alloy to me at all. There is a reason they put a "FOR EXPORT ONLY" sticker because it would be illegal to sell that POS in China.

    @JohnMc, don't use adapters. Buy some IEC cables with type I plug instead. If Aussie cables are too expensive, get Chinese ones, they are basically identical (both Type I) with the only exception being the Aussie version has very slightly thinner blade copper with a plastic coating and the Chinese version has exposed copper blades. Big brands like Volex and Longwell make top quality Chinese plug IEC cables and they are available for ~$2 each. For those Type A wall warts, you do need to find an adapter-based solution.

    Or... get one of your local power boards with 4-6 sockets on it, cut off the wall plug and wire in an in-line IEC socket, then all you have to do is buy an IEC lead when you get here.

    Finally, a decent meter :) Just as well the seller packed it really well because the box had a 4" hole in it - box handed to me on the doorstep with the hole underneath so I wouldn't spot it... Thankfully the meter survived though.

    Yes, Deathdaptor. Was chuckling to myself as I bought it.  Only going to use it for my phone and maybe my laptop if I take it with me for a couple of days.

    Actually was thinking of doing a IEC power bar the other day. The UPS we got for the office came with a almost full world set of IEC cables.

    Finding a good power bar/board in Thailand can be a challenge.
     Just a couple of the faults I have seen - Universal sockets that also take finger tips.  :palm:
                                                             - Ungrounded type plugs or sockets
                                                             - Grounded type plugs and sockets but only two strand wire.  :palm:
                                                             - 0.5mmsq wire  :palm:

    Snap. Ordered the same thing from HK yesterday (different seller though). Be real interested to hear your experiences with it.

    What software you intending to use with it?

    Not decided yet but I think I'll start with some Python scripts and my 34401A meter.
    I'm not experienced in this kind of stuff, so I need to play around a bit with it.

    Later, some other meters will follow, e.g. a DMM 7510, Prema 6040 S etc.
    The 8357B will arrive end of April, in the meantime I'll look for some GPIB cables. :-)

    What Weller are you coming from?  I ordered the ADS200 - been using a WES51 for a long time.

    Yup same here! That thing is like a tank and just keeps on going.  We got hakkos/weller at work, they are nice too. Our main tech has a full hakko setup and its pretty nice

    Finally, a decent meter :) Just as well the seller packed it really well because the box had a 4" hole in it - box handed to me on the doorstep with the hole underneath so I wouldn't spot it... Thankfully the meter survived though.

    Can I ask how much you paid?
    I’m in the market for a new meter too.

    Tossing up between an old keithley or a new(ish) Agilent, but the prices are a bit painful for the home lab!

    Ps: nice workspace!

    I paid £360, which is probably about the going rate for these in good condition.

    Edit: A cool idea I just had - one of the problems with many filaments is they are hygroscopic and need to be kept dry, they are transported in a plastic bag with dessicant inside. Of course, as soon as you take the spool out the bag it will start to deteriorate unless you take steps to prevent it (construct a dry box for example). With the spool rollers I figured I could just put the roller inside a large sealable bag, with dessicant, and the filament then pokes out through a tiny hole. It can be used this way and will stay dry. Seems to work fine!

    I can't recommend those small sachets, you can't see when they are saturated and you need a larger amount to actually get the moisture out of there properly. Search for "Silicagel Orange", that stuff changes color from orange to green, depending on the amount of water it sucked up. I ordered 1 kg for 15 euros from Amazon. Then order a few hygrometers from china, should be 1 euro per piece. Put them in the bag and measure the amount of moisture semi exact.

    I ordered a bunch of 250g spools as well recently, bronze, copper, alu, carbon, wood and one plain ABS. Can't say i have ever used something else than PLA.

    You're right, and I do have a 1Kg jar of the indicating gel (Blue>Pink stuff). I guess I need to print a small tray with perforated lid to fit underneath between the rollers. You can rejuvenate silica gel in a kitchen oven when it gets saturated, not sure about the stuff in these satchets though.

    Last spool I bought (and using right now) is 2.5Kg of PETG (https://www.amazon.co.uk/gp/product/B06XKY3RRN/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 (https://www.amazon.co.uk/gp/product/B06XKY3RRN/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1)) - it's huge so I'll have to find a larger bag :) It's the best stuff I ever printed with and will never go back to PLA or ABS - other than to use up existing stocks. Not all PETG is good, two other brands I tried previously were not as good even though they were twice the price.

    Packed up some stuff that was sold, so the 300x300x700 high unit was slightly changed after packing to 450x450x900 in a cardboard box, cushioned with plenty of extra cardboard as padding, bubble wrap ball on all sides well taped together, extra cardboard padding top and bottom and then an outer box to cover it all. Might get there unscathed, but every side has a fragile sticker on it.  Added around 5kg to the mass with all that.

    Courier was supposed to collect between 2PM and 4PM, but of course never showed up at that time, and when I left nearly at 5PM still no show.

    Company that made the equipment was UK based, went belly up around a year ago, so no longer really around to support them, but there are spares available still, or you just machine them out of appropriate materials. Has a mains filter in it, dating from 1988, but not made by Schaffner, instead a Bulgin one, made using separate toroids per line and non RIFA capacitors, so still perfect after all this time.

    Just picked up a used Siglent SDG2042X because of the great thread here.  I waffled over the purchase for a while.  I'm ashamed to admit I ordered it, cancelled it, then ordered it again.  :palm:

    The only issue is that I already have an almost new SDG1032X.  I told the wife that I would sell the 1032...

    Computers are starting to catch up to the TE.  I have almost as many PCs as I have multimeters. |O  CEA (computer equipment anonymous) for the next thread, maybe?  Just keeping them out of the landfill. ;D

    Yep, mine has that dual zone air con as well, surround sound from 8 speakers when in cinema or TV mode from its built in DVD or TV Tuner and a host of other bits and bobs that I never had on previous models.

    Limousine like space inside with loads of leg room for 4 x 6ft 4inch tall people even has foot rests in the rear and electrically heated seats all round with cooled seats for the driver and front passenger alike, lovely car.

    I finally got around to buying a decent Knipex automatic wire stripper, just got sick of using various manual strippers with varying results and consistency.

    Finally, a decent meter :) Just as well the seller packed it really well because the box had a 4" hole in it - box handed to me on the doorstep with the hole underneath so I wouldn't spot it... Thankfully the meter survived though.


    Chris
    Can I ask how much you paid?
    I’m in the market for a new meter too.

    Tossing up between an old keithley or a new(ish) Agilent, but the prices are a bit painful for the home lab!

    Ps: nice workspace!

    I paid £360, which is probably about the going rate for these in good condition.

    Yeah, that’s about the going rate I’m seeing too ;)

    On expectation of delivery of 5 Raspberry Pi's (from TopLoser on here) I bought a load of extra stuff - small keyboard & mouse, L298N driver boards, and too many other small bits to mention. Also 3D printing some pi cases and a tracked robot I will be making.

    (https://farm1.staticflickr.com/804/41165276782_6fa73fab9f_b.jpg) (https://flic.kr/p/25HCNBq)

    ...and the printer working on robot bits (apparently slow because it's currently on the outer shells which are done at reduced speed). Two 3Kg PETG spools loaded (black and white) onto my home-made spool rollers.

    Some crimpy sockets (BNC, N, SMA)  for RG174 and a crimping tool, along with a strange BNC socket for with screws. Also some protectors for RG174.

    Btw, does anybody know if there are different dies available for this model of crimping tool ?

    Can you remove the dies from the tool in just a sliding movement or clicking then probably yes.
    If it is stuck as it looks like then probably not.

    Yes, they slide and are hold in place by a screw, please observe the picture, if anybody know the model or specifier, if any,  will be very glad to know.

    Faster response - up tp 1k smaples/sec. I didn't reckon on the distance it sticks out the back though, a bit inconvenient.

    I know this is the where the electronics porn watchers hang out so I thought I'd share a bit of Andonstar magic.  All should be linkable to the full 12Mpixel originals.

    Symmetry.

    Remember, power LEDs can do interesting things is you let them:

    I got away with this... the chip shifted during reflow!  (The bridged pins are actually meant to be (they are linked through the pads with no solder mask):
    (http://i.imgur.com/FeA41QY.jpg) (https://imgur.com/FeA41QY)

    Another shift.  Lesson learnt, the board MUST be level when it reflows, I was holding the board in pliers at an angle.

    Nice pics, but you would benefit from fitting a light ring to the microscope body if possible, to remove the uneven lighting, which model of microscope is it that you have?

    The Andonstar M201.

    I like the uneven light for photos, but the little stalk LEDs can be a bit annoying when working under it, moving the board around etc.

    I might consider an LED ring light.

    This was the second of this board.  "Flow" rather than "Reflow", but both worked first time.  I know I probably should have reflowed and realigned the PCM chip, but I got lazy and didn't want to stress it.  I tested each pin with a multi-meter and plugged it into the PC USB port.  Worked straight away like the first one.

    Hot air with an 898D clone.  Seems to work quite well, but anything plastic or that sinks heat I tend to do with the iron, like jack/dc sockets, SMD electrolytics etc.  I found the plastic would sometimes melt before it flowed properly.  For the SMD jacks I spread paste on the pins but then touched the iron to them instead.

    My auction win arrived today :)

    Vision Mantis Elite V2 with x15 optics.
    I ordered a x4 so I should be set for both SMD soldering and inspection in the future. Loving it so far! Very crisp image and I am astonished at how well the LED lighting works. Brightness is very even and just right.
    The x15 optics has some minor scratches on the bottom side, but this does not seem to affect the image. As you can see it came complete with the anti-reflection hood (very handy with a window near by).
    We’ll see how the multi-purpose arm plays along, should be good with lower magnification - the short focal area of the 15x is a bit more picky, but maybe I just need to tweak the spring settings of the arm a little.

    I also got a very cheap little G600 scope, but after seeing the toys you and Paulca aquired, it is not even worth calling it a microscope.

    I bought one of these Orico drive docks last month and just got around to checking it out. It seems to work fine, not bad for $22 (shipping included). I also got a Rosewill external 2.5" drive enclosure for $9.99 at the same time. No problems there either.

    The G600 isn’t half bad as a soldering aid :) Considering bang for the buck it is very useful IMO. I would choose that over any USB microscope hands down. There is nothing worse than having to solder with screen lag from low data rate over USB.

    Yeah, at the moment it is sufficient for me. Due to Diabetes my eyesight is pretty poor and it helps a lot with regards to the smaller stuff. I haven't soldered anything really small with it yet. I'm waiting for a small practice board with some smd components, but that will only arrive in another two months or so.

    Out of curiosity: Are you printing tracks from flex filament or interlinked solid parts? I remember having both options on some LEGO models back in the day and I always loved the look and feel from the interlinking ones. From the sturdiness and printability side I guess flex filament is the sane option but it is not as cool :)

    Arrived today and punished a bit. 180W DC load. Has some limitations but suck per buck is great. I also got its baby 35w brother which is a good bench toy.

    Big one has no remote sense so I broke out the 10AWG gold test leads  8) 0.15V drop at 15A including connections will be fine for most jobs. 84 degrees was the most it got to so it could be pushed toward 200w I guess.

    Snap of typical test leads against the heavy ones. Nearly 2v drop at 15A on them.

    If those smaller leads are 18ga I'm not surprised as they are rated at 7A maximum capacity.

    Nothing on the outside of my standard test leads but I am sure the molded plugs won't be helping either. I wouldn't push them beyond 5A on most of my bench stuff. I have a bunch of shorter test/charge 10-12 AWG leads from Model Aircraft use.

    I would have preferred to jump into a better quality load with more bells and whistles but this one for brute force with some extra meters doing the readings will do me for now.

    Rhinotools a great way to spend money that you don't really need to  :)

    What does the box joint feel like on the Fujiya's?

    I bought some Engineer NS04 micro nippers a while back (looks like they are no longer on their site :( ) and also the Fujiya long nose pliers https://rhinotools.com.au/product/long-nose-pliers-2/ and was a bit disappointed with the joints on the Fujiyas compared to the Engineers, they were very stiff and took about half an hour of constant opening and closing and some oil to get them to open with the spring. In hindsight I should have sent them back.

    Hehe, not wrong!

    The joint on the Fujiya's feels very snug but the friction levels isn't excessive, it works exactly as it should.

    Sounds like your pliers might have been defective.

    First decent hand tools I ever bought were Klien pliers.  I have tortured them and the blades will still cut a single strand of hair.  That's the 8" pliers!  They will also cut a motorbike steal 2mm clutch cable in on simple CLICK.  Also have needle/tweezers point pliers from them that are so pointy you could stab yourself with them.  I have tortured those too, bending things, prying things etc.  The point still meet accurately enough to pull a single hair out of your head.

    The 8" pliers however are about £100 retail.

    They do a set of flush side cutters for £10, which will probably be what I replace my chinesium cutters with after I chipped the point cutting something I shouldn't have been (the hard plastic cover off a 5mm spade connector).

    That cutter is for snipping parts from plastic sprues, ie model building. http://www.fujiya-kk.com/en/products/12/ (http://www.fujiya-kk.com/en/products/12/)

    True, however they are awesome for snipping through hole leads and the cut is very high quality.

    My Metcal heavy-duty low cost tips from a French guy arrived (one is not like the others   ;) ), plus a strange lamp from Grundig (it's just some label now, like Polaroid) that has some extensible and flexible neck and a magnet in the behind (for picking up droped screws/parts).

    Got some new toys during my easter holiday:

    edit: I changed the ram battery in the HP3457A and modded a backlight. I also calibrated it.
    The Fluke 25 had broken input protection but now it works fine again.
    And last but not least a Tefifon. Its a type of record on a tape player. Basically a record put on a plastic tape in a endlesss loop. The cartridges a calles Tefis. I modded the Tefifon, because it had no fuse, no earth connection and I wanted all cables to be pluggable and a preamp inside it.

    Thanks to IRFP460 for letting my send the stuff to him, so I could save on shipping  and for helping my with modding the Tefifon case.

    1 strange thing that has happened since I got it is...I was stripping heat sinks from a board a couple days ago and the gun was just fitting over the large solder pins with very little to spare. I go yesterday to strip the rest of the stuff off and the damn thing won't fit over the pins any more! It's the same pins, same heat sinks, same boards and same everything....AARRGGHHH!!  :)

    Haha, it turned out to be nothing other some solder that had coated the internal bore of the tip and hardened, passing the cleaning rod though it a couple of times cured it perfectly. I'd be a bit concerned if the tips didn't last really, they aren't that cheap for mine.  :popcorn:

    Well knock me over with a feather, you're right they are super cheap and I might have to take a few of those off their hands. Thanks for the offer of assistance if they don't ship to the UK, but I don't think thats going a to be a problem as the site understands I'm in the UK and adjusts the prices over to GBP so it all looks good, nice one.  :-+

    That arm is to hold thru-pin parts in place when you flip the board over to solder the pins, it doesn’t really provide any meaningful thermal Absorption.

    Right, I used this to solder the DIP socket and MIDI connectors when I sold my C64 Kerberos MIDI cartridge:

    (http://www.frank-buss.de/kerberos/orientations.jpg)

    because additional cost for through-hole assembly is costly when you produce it in Germany. But I guess it is resistant to high temperature, because it doesn't melt or smoke, even if you solder pin headers, which is really nice with this frame, because no burnt finger nails anymore, especially when you try to solder one pin :)

    Nice.

    I generally use electrical tape to hold TH components in place when the PCB is upside down, however it has issues like softening. I might try kapton tape in future.

    The #6 oil ring sheared off and gouged the cylinder wall, so the "old" aluminum block with it's 55K miles is the new garage wall ornament... the fresh build is going back into the '01 F body Camaro, or at least that's the plan at the moment.  My buddy has been tossing around the idea of converting it to carb and sticking it in a Miata or S2000 body, but I don't see that happening right away.  It'll more than likely stay in the F-body, which will get a new stall converter (yes.. it's an automatic... E40D) and Ford 8.8" or 9" rear end swap in the near future.   

    We're curious to see whether the car is going to want to lurch forward at idle with the 112 LSA camshaft and Wilwood ABS delete since the new stall converter isn't happening until later. Other than replacing some fuel injector connectors, the only electronics related work I've done on that car is to pull the ABS indicator LED from the instrument cluster!! We're running a mail order tune on it until we can secure some dyno time after break-in...  Do any of the LS gearheads reading this have any recommendations for US based mail order tunes??

    I can't wait though... to top off the greatness, we're painting it burnt copper and leaving the LS6 intake OEM black.. It's gonna be sexxxxxxxy!!

    Heading over to the garage now to install the camshaft, timing set, oil pump, and heads!!

    Thanks for this - I've been looking at getting one of these for a while but didn't know if it would bypass customs/VAT etc as much from China does. I'll have a rethink as that is a significant charge. Did you get it from Japan?

    Cheers

    Yes Japan buddy.

    I remember when I was looking at getting 1 and researching them I read/or heard(can't remember) that the ones sold from China weren't as good as the ones from Japan. I can't remember the reason but I for sure was swayed to the Japanese sellers. I'll try and find where i heard that and let you know.
    I also did the kelvin clips upgrade and would recommend that too if for no other reason than the longer leads are so much more usable. The guy on YouTube who first did the video of the upgrade did it for more accuracy too but i don't need that kind of precision myself.
    I would recommend getting 1!

    Good luck however you decide to go...

    The croc clips that come with the meter are decent quality too so I will probably join them up with some decent leads so they won't go to waste. I have just not long made a set of croc clips up that I would have used them for but i'll just need to make another set now  :D
    The tip broke of one of said probes so I just cut both the probes off and used the leads with a pair of croc clips I had and it ended up being a decent set of clips. Very handy  8)

    C'mon!
    It's from HP.   >:D   :popcorn:
    And it's a 500MHz Scope with 2GSa/s -so it's actually a 200MHz to 300MHz Scope compared to today's standard. Ok, with an 500MHz analog front end.
    I remember 4-Channel Philips 200MHz scopes with 200MSa/s that where (and occasionally are) offered for weird prices of modern 200MHz scopes..  :palm:

    BTW, offered was a model without any option!

    Reality check:
    The last one sold on *ebay went for EUR 430,00 in Germany.
    But prices of sold ones in the US start at  US $232,50 for a unit with extra storage, FFT and HPIB option and end at US $675,75.

    That is for sure a "240V-110V building site transformer" for plumbers and electricians and folks like that to work from. In the UK all powered hand tools and things like that have to be 110V on the sites.

    Sure, the traditional tear-down before power-up and the "before" and "after" pictures of the treated tubes will be in this thread. Stay tuned for the news.
    Actually I've read that some guy used some improvised method and "only" got 1000 hrs !!! of good brightness from his almost fully dead SA tube (he let the SA run continuously for like a month an a half) ,  I would say that if one gets another 1000 hours of operation of his device, it should be good.
    Let's see how this professional thingie, that was ridiculously expensive some while ago, will behave, the arcade games people are quite happy with it.

    It is definitely 240V to 240V (ie one to one)

    It is in the style of a building site isolation transformer.
    Yes, they are normally 110V outputbut this one is not.
    110V normally has a Yellow socket. I think blue and red sockets mean 240V or 3phase 440V

    Not sure why this one has the 16A 2P+E socket on it. Yes, I was after one with a UK 3 pin mains socket but I got this one for £40

    I had been watching ebay for ages for one  :D

    After two unsuccessful orders I finally got the 4x optics for my eBay snipe.
    Company one sent an invoice with a ridiculous price, almost twice as much as advertised on their site, company two took the money and was not able to fulfill the order, though the optics were shown as stocked in the web shop. After not hearing from them for over a week I called and they said: well, we can not get that from our vendor - they are going to refund.

    Finally, Distrelec was able to supply me with the long awaited MEO-004 - very fast shipping and the price was OK, compared to what some other resellers are asking.
    In general I think that Vision Engineering gear is a bit too much on the pricey side. After all, the 4x optics is only a single lens in a very simple aluminium mount. For a little under 200 € that is not exactly a bargain. Sadly I could not find the 4x as used item.

    Well I've been busy on Ebay this week which seems to have picked up again, the last few weeks since Christmas it has been shit and out of the dozen or so items purchased these 2 are by far the best and most interesting items. I have been after a decent AM/FM RF signal generator, one that actually has proper FM modulation and sweep function beside the AM modulation for ages now and fingers crossed I've found one, time will tell when it arrives but it was listed as working.

    The HP3478A was also listed as working and sure enough it is working and appears to be still in calibration so that was a real bargain.

    Fluke 742A-10K

    Born 02-Nov-99
    Nominal value = 10.000024 kohms
    Alpha = 0.030
    beta = -0.015

    Looks not too bad on a 3458A with an unknown last cal date.

    Ahhh, you grabbed it, I was too slow.
    I looked at it and before I could hit the buy now button, it was gone, LOL.
    Nice catch, now you can calibrate your 3458A by yourself for the resistance.

    FWIW, based on manufacturer P/N's on Jameco's site, they're from Wisher, which makes decent products.  :)

    Two months ago, when I bought a Raspberry Pi at an online shop in Australia, I bought two breadboards by the way. After I received them, I did some simple tests and found that they were completely useless garbage. So I went to Amazon and bought some Jameo's.

    I have attached two pictures, you can see the difference between them!

    I'd guess the crappy one is steel rather than phosphor bronze in the Jameco/Wisher.

    Well, if it has to be steel, 5160* would be a better choice IMHO (HRC of 63 & can handle a lot of cycles). But for what it costs, you might as well use phosphor bronze.  :-DD

    I bought one of those Jameco breadboards years ago. When I saw the color, I asked them if it was defective and was told that was the color they were supposed to be. Maybe it's supposed to be easier on the eyes or something, but I personally dislike the color yellow so I never bought any more.

    Some of those jumpers in the 2nd row don't look like they are fully inserted to me. If so then thats certainly going to add to the resistance measured.

    I have a smattering of various breadboards from China, plus a good 3M one.

    Most of them have negligible contact resistance, but I found one or two Chinese ones that have something like 2 ohms resistance on a single contact row. That said, it’s often just a particular contact row that’s problematic. So a series resistance test as in these pics here might really just be showing a few failed rows, while most rows are actually just fine. This, in turn, could be due to poor manufacturing, or due to the cheap contacts being damaged by inserting oversize leads (like a TO-220 without twisting the legs). Quality breadboards are more resilient to such abuse, but not immune to it.

    One can never have enough 34401A's and they are easy to find in broken state.

    And they are fun to repair, since all schematics are around.
    The first one has somehow a broken display, like it is completely dead.
    However, it works perfectly over GPIB.

    Hummh HV, if they are so easy to find in broken state, could you share one place where one can easily find them in broken state, 'cause fleabay and kleinanzeigen for sure aren't one of these places  :-//.

    Or maybe if there is so easy to get, you can divest yourself of one, for science you know  ;), I always wanted to make a display simulator, but my displays are working OK  :'(.

    Fluke 80E 10kV divider with 1:1000 and 1:10000 outputs.
    Accuracy of 0.01% and north of 28ºC this derates at only 2ppm/C , even so at a 10kV input, which at 10Mohms amounts to 10W. Resistors are wirewound not metal film so there must be a lot of good resistive wire inside

    After a long time looking for a decent AM/FM RF signal generator and buying a few lame ducks, it seems that I have final found a good one, British made as well, well build and heavy.

    Cleaned it up, opened it up and checked for anything obvious that was wrong/broken, powered it up and hey presto, not only does it work on all wavebands but its pretty much bang on frequency with 3 bands being spot with the dial indication and the 2 highest bands being 11Mhz out. Coupled with a decent British made frequency counter, I'm calling this one a home run.

Hell, this thing has not one screening tin/box inside covering the oscillator section but two of them. Its built like battleship, and inside is a work of art.

    Yes, I have a TF1370A, waiting for me to tackle it.. there was some interesting flash-over evidence inside, as well as a decapitated SQ valve and a completely incinerated PTC thermistor. That thing would anchor a Dutch barge. I got it when my camera was on the blink and haven't gotten round to taking any photos, so I looked for an example pic and found a photo from the original listing.... I recognized the yellowed type-written note about switching transients due to crappy caps. It's much, much cleaner now and I will take a couple of snaps later on, another fine example of British engineering.

    Yes they are nice but that Marconi one is just so huge, it had to go as far as I was concerned as it just so heavy to have up stairs which is where my lab/bench is located in the boxroom ( they called it 4th bedroom, 1.6m x 3.3m a bedroom  :-//  :-DD

    It seems both Marconi and Advance were used by the British Military as well so they must be of a very standard to be used by them.

    Yes, we're a navigation marker for the Mach Loop, I think. They line up with one end of the lake and then swing around the mountain at the far end. Because it's low level you don't get to see them for long, and it's too cloudy today - as it often is. My nephew has found a spot you can drive to and watch the jets down in a valley from above. Some of the on-board videos are amazing; the skill of those pilots! I've also seen, only on video unfortunately, an AC130 taking on the Mach Loop. Seeing that monster at low level standing on its wingtips would be a sight to see.

    Perhaps one day my son and I might make the journey down to get some photos in the loop. We often go to RAF Lakenheath where they fly F15's and almost daily they fly through the Loop, come back, refuel, change crews and take off and do it all over again. When you see them in the loop on video they are pretty large beasts as well. I did manage to photo the Vulcan from above at Beechy Head a couple of years ago on its last flight at the Eastbourne airshow, awesome beast that was too, there's a couple of my photos here on the forum of that too.

The cafe has also meant that I might have to get myself a Fluke DMM to keep track of the fridge and freezer temps with a bit more accuracy than they have managed so far.... that's my excuse and I'm sticking to it.

    I got myself a 2nd HP3466A and it appears to be within calibration as shown against my other one and connected to my voltage reference module. Sadly though, because of poor packing the handle is in 2 parts but I did get a partial refund to offset it. Time to break out the superglue I think and see if it will stick this type of plastic.

    Thanks for that but I doubt it as the plastic looks to be of the oily type so I suspect that it needs something like the Gel type of superglue. I can but keep trying till I find something does work.

    You could drill it and pin it. The trick is to get the two halves to line up, but with half an inch hole in either side and snug fitting brass or ally tube and thin cyanocrylate will make it strong enough to use to carry it with. If you can get hold of PC-80 vinyl superglue (150 Kg per sq.cm) you'd be able to hang off it. The first version would do fine for sitting on the stack, though.

    E2A: If you're left with any gaps where shards of plastic have gone, fill the area with thin or gel cyano and then sprinkle baking soda over the joint. Wherever the baking soda mixes with the glue it will cure instantly, leaving a rock hard, sandable, paintable surface.

    It's not just me that does this! http://www.instructables.com/id/Baking-Soda-Reinforcing-Glue-Repair/ (http://www.instructables.com/id/Baking-Soda-Reinforcing-Glue-Repair/)

    I repaired the filter capacitor box on my 2467B (yes, I snapped off the little lug in the middle), but I drilled it, pinned it, and filled the gaps with SG/BS and it's strong enough to use as normal, I've had the top on and off a few times since just to make sure. That is the same type of plastic or similar. Solvent glues didn't touch it.

    I've just remembered that when I got my first 3466A, it too had a broken handle and it was photographed and displayed on Ebay with it so I knew it was broken and in the same location as well strangely enough. I managed to repair that one to the position where today I can carry it about with impunity if I wanted to and I used Loctite Gel power flex glue for that so I've just tried it again and now I just need to leave it along for a few hours to see if it works again.

    Nice one!  :-+

    It sounds as though HP should have had a metal rod going through the handle anyway. All plastics tend to get brittle as they age. I think the Loctite glue is quite similar to the PC-80. I'm not sure what Loctite add for the flexibility but that is what the vinyl is there for in the PC-80, it makes a big difference to the shear strength, superglue's only real drawback.

    Don't laugh, but if you happen to give yourself a cut that needs stitching you can patch yourself up with superglue a treat. I believe the cyanoacrylate formula was developed as a field-dressing during the Vietnam War. I can't stand car travel, the vibrations are agonizing to me, so I've often resorted to superglue after doing something stupid rather than have an hour of torture in the car, followed by 8 hours of torture sitting in A&E.

    Yes I think you are right, I remember reading that before about it being developed by military doctors for battlefield situations in a bid to save lives as many were being lost before they could get them to a hospital for surgery.

    Can't expect too much from the plastics after 34 years but it is a testament to the overall design of the meter that it still reads within its specification of 0.03% on DC voltage and the rest of the meter still seems to be pretty good to me. When my HP3478A comes back being calibrated, I'll using that as a transfer reference to set up my other meters including the 3466A as they all have manual adjustments unlike the 3478A.

    Sorry to hear about your problem with vibrations so I can imagine the agony a car journey would inflict on you especially with the potholes our roads are riddles with these days.

    I was told we'd have hover cars by now, when I was a kid. I feel so cheated!  :-DD

    I can totally forgive HP for plastic issues. Complaining about the trim on such superbly engineered devices seems churlish in the extreme, especially as we must be well outside their expected length of service. The fact that you can buy a meter with a cal sticker that expired ten times it's renewal period ago and you can still have a reasonable expectation that it will be in spec is incredible really.

Its the rage to go small with everything these days apart from TV screens.

    I just had a look online as I thought they were some cheap no-name company and somebody tossing them because either they broke or got water damaged or maybe speakers were blown. But no... they sound in good nick and loud and clear as heck! The towers were wrapped up in Saran-wrap like material to protect them, the woofer not. And it just rained hear briefly a few hours before, not sure if they were outside or not then. There are a few scratches on the faux-wooden veneer/laminate but superficial and one of the speaker covers has a little wear at the fabric near one of the edges.

    They were definitely on the curb next to the large black bag garbage, recycling blue boxes and green organic bins and today is definitely garbage day on my street. I'm sure I didn't just steal them.... Why would the towers be wrapped in that clear film? Were they in storage and they just wanted to clear space because they got news ones a while back? Seems odd somebody would toss them but I guess if somebody is buying audio systems they will pick up a new array of home surround speakers and these would be redundant and perhaps not match the decor and with only 3 speakers (and they are a bit heavy and large) I assume if they bought something new it would have a bunch of small ones everywhere mounted to walls and such and have like at least 5 or 7 around the room from all directions. That's one explanation I can come up with.

    And yes they are definitely better than what I have now, which are a pair of also curb-thrown speakers which I picked up with an amp/tuner/double cassette. Of course the cassette decks were done long ago (belts dried up) and I nevertheless bothered to replace them. But I use the AUX in to plug an iPod or computer or phone, and I get a nice crystal digital tuner to pick up local stations... and it has a cheap equalizer with maybe 5 or 6 sliders. Anyways the speaker that came with that were pretty good but I only noticed last week (after Dave's speaker tear down) that my own had one with a blown tweeter. Of course I never noticed because the other speaker still had a good tweeter and they are set up so I couldn't really notice it unless I moved the balance fully over and jacked up the highs on the equalizer sliders. So talk about timing... what a coincidence that I see Dave'a video, which makes me poke around my own speakers, which I then discover one tweeter is fried and then poof out of nowhere these new speakers! I really need a new amp/tuner though... maybe someone will toss something better. LOL!

    One day someone will have a bonanza when I start dumping my stuff too because running out of space and the wife making me clean everything out! Only temporary possession, that's the truth! My dumpster garbage finds likely been around the block a few times!

    Maybe they hoped they could be of more use to someone else, and wrapped them up so they stood a better chance? Free-cycling.

    Btw, the third speaker is a center channel, not a woofer. Normally is used only with TV/home theater setups that have multi-channel surround (it is the odd speaker in 5.1, 3.1, 7.1, not the .1 speaker). They tend to be somewhat lacking in bass, as they are mainly intended for dialogue reproduction.

    I need to confess..

    Some days ago I acquired an almost NOS Vision Engineering TS-4 that is now sitting on my new bench. I already posted about it of course ;)
    However, the guy that sold me the microscope had a deadly question to ask:

    Are you interested in parts?  :-//

    Well... what kind of parts?

    All kind of... I don’t know.

    And then he dragged a huge box of IC tubes from a shelf and some cardboard boxes full of SMD parts, connectors and other goodness.

    SCNR!

    There are a lot of EPROMs, CPLDs, 74XX, ADCs, DACs - you name it.
    I already started cataloging the parts, but it is still a long way to fill the database...

    Thanks! I'm not very familiar with home theatre audio. The only experience I have ever had was my parents old Mitsubishi amp/tuner/phono with a turntable attachment and a couple of basic speakers (early 1980's mid-grade consumer stuff). They still have it by the way! I remember after powering it on a few minutes sometimes you would hear a loud pop and then no more sound for a while (the limiter relay or something clicked to protect the speakers?) then eventually popped on again and you could play sound again.

    So I haven't attached the CC100 yet, not sure how... I only have left and right speaker connectors on the back of my tuner/amp. It's that Hitachi HRD-MD03 attached in the photos which I hooked up to a pair of Kenwood LSK-500W's also shown in photos (also garbage curb day from a few years back). That was my only audio component system until acquiring the JM Labs.

    Did some more research, apparently the JM Lab Chorus 715's and CC100 are quite "old". The company changed names to Focal and you can still find Chorus speakers under that new company somewhere. The older brochure found here shows what seems to be the original branding: https://www.canadianhifi.com/sites/default/files/product/749/manuals/JM%20Lab%20Chorus%20Series%20Speakers%20Brochure.pdf (https://www.canadianhifi.com/sites/default/files/product/749/manuals/JM%20Lab%20Chorus%20Series%20Speakers%20Brochure.pdf). Made in France. I attached a photo showing serial number, not sure if there is a date code in there as I saw online reviews in the 2003-2008 range. Back then a pair would go for maybe $800 and the centre speaker another $300, and most reviews were pleased with the sound for what they considered a "cheaper" audiophile set of speakers. They also commented they were heavy. They are made in France to all of us French forum members. I would expect well made speakers treated well to last... the materials don't dry up into dust and degrade as fast as before... I don't see why if these speakers are at least 10-15 years old that they can't last equally that long again. By no means are these "vintage" (except maybe the look is not modern).

    I've ruined a couple of pairs of standard cutters by cutting hard wire and I seriously doubt the accuracy of the hardness ratings of those. These new ones are not exactly bullet-proof either, carbide is easily chipped through misuse. I was impressed by their proper box-joint design but less than happy about the finish on the ground edges, they do work though. I had contemplated returning them but I guess I'll live with it. There isn't a huge choice and I wasn't impressed by the many 'dental' carbide cutters on the market.

    Picked up some used but still relatively fresh solar panels from a guy on ebay. I was able to pick them up during my lunch break at work for essentially free shipping.

    230W panels for $120 each and when I was there he had an extra so I got a 4th panel for $110. This will bring my total theoretical power capacity to 1.6KW for a total cost of $670 (not including mounting hardware, wire, etc)

    In this case I can not blame Engineer for a poor tool. I was being really stupid // careless while working on my Rhodes piano. I had to cut one winding off of a tuning spring (that slips onto the tines) and just grabbed the next tool at hand.
    Maybe I can regrind it since "only" the front part got molested.
    At 18 - 30 € it is not the most expensive tool ever, but I really liked it and replacement orders take quite some time since all sellers seem to ship directly from Japan. I have some of their tools and would recommend each of them any time!

    Dropped a couple of hundred $$ and made an approximately 7 hour round trip up to New Hamster to get a bunch of boatanchors from a ham who was looking to make some space.  Among the haul are a couple of signal generators, two 8443A tracking generator/counters and a 5245L mainframe (my DVM plug in will have a permanent home).  There are a few assorted manuals, too; didn't look to see exactly what for though.

    I have an 'over the shoulder' pic, but everything is still in the Jeep as it started pouring when I got home, and though it has since stopped I don't feel like going outside and schlepping everything in now that it's after midnight.

    I have this one (http://schmitz-zangen.de/artikel-tungstencarbidesidecutter-3437HS22-2-engl.html) and I can really recommend it.
    Not the cheapest, though.

    Scored this bad boy on fleabay today for $240 + ~$10 gas money to pick it up.

    (https://i.imgur.com/WmLkOiG.jpg)

    Does not seem too much out of spec, but I don't have anything accurate to test it with. Waiting for ad588 based voltage reference in the mail.

    I will look for a good set of leads for it.

    Also while the screen is bright enough there seems to be an issue with the driver leaking current into some segments, you can see random dots and 4w symbol appear in the photo when they shouldn't. Mine is I think the old version with 34401-66502 front panel.
    Anyone knows where I can get a replacement? If only new version of front panel is obtainable, are there instructions on how to update firmware (if that is even an option)?

    I bought an Agilent 8110A some days ago:

    (https://i.ebayimg.com/images/g/meQAAOSw2fRaqxX0/s-l1600.jpg)
    (Photo linked from ebay)

    It's my second 8110A. My first (a HP 8110A) one came so badly beaten up through transport that I got full refund for it.
    According to the description it's fully functional -meaning that it's not really a bargain using it for parts..  :palm:
    Actually I just need the front panel with the display to fully repair my unit. Or in other combinations: making one good out of two.

    This one has also chips on the front and dents in the metal parts but the mounting points of the front panel are all intact and the display seems to be much better than the one of my HP 8110A.  :-+

    The display is bright and doesn't show much burn-in wear-out:
    (https://i.ebayimg.com/images/g/pykAAOSwygtaqxYF/s-l1600.jpg)
    (Photo linked from ebay)

    The chips might be repairable with some heat and glue.
    I hope, I'll receive this one mechanically undamaged.   :scared:

    May sell the second unit after repairing the first one to reduce over-all cost for this repair...

    Dropped a couple of hundred $$ and made an approximately 7 hour round trip up to New Hamster to get a bunch of boatanchors from a ham who was looking to make some space.  Among the haul are a couple of signal generators, two 8443A tracking generator/counters and a 5245L mainframe (my DVM plug in will have a permanent home).  There are a few assorted manuals, too; didn't look to see exactly what for though.

    I have an 'over the shoulder' pic, but everything is still in the Jeep as it started pouring when I got home, and though it has since stopped I don't feel like going outside and schlepping everything in now that it's after midnight.

    New main board off ebay for my Wanhao Duplicator 4S 3D-printer. I was replacing one of the internal fans a few days ago because it had gone noisy and noticed the power socket (top-right) had burned up - lucky find because I had no idea! I'm guessing the plug/socket went high resistance and heated up. Also, the USB port has died for some reason, whether related I have no idea. The USB port is not essential because I mostly print from SD card but it's nice to have to monitor progress on the PC. I'll see if the old board is repairable when I take it out.

    Still cheaper than the CK Tools branded version @ 78.99GBP on Farnell though (T3787DF 115 (http://uk.farnell.com/ck-tools/t3787df-115/cutter-tungsten-carbide/dp/1465985?st=erem%20tungsten%20carbide)).  >:D

    * FWIW, I picked up a used pair of these in good functional shape for ~$15 shipped (cosmetics were fixed with a bit of steel wool).  :o My oval pair is a Swanstrom M509 (https://www.jensentools.com/swanstrom-m509-medical-device-esd-safe-medium-short-nose-diagonal-cutter-semi-flush-4-75-long/p/476-597) I snagged for ~$10 shipped IIRC.

    The banana sockets on the 3721A are for voltage sensing. I think the input for the load itself is the same on the Maynuo. Or does that lack the holes?

    Correct - no holes! Needed to add a couple of adapters made from 3mm copper.

    There's a version of the ubiquitous German halftrack of WW2 called the LWS, or Lichtes Wehrmacht Schlepper. I think that was mainly used for schlepping.  :D

    My 2465B was really clean. the only potential issue I could see were some green pins on the SMD electros on A5 and (of course) the Rifas on A2 have evidence of crazing. Goddam crazy Rifa, all rolled and ready to smoke. Despite the likelihood of sending smoke signals across Snowdonia I think I will fire her up.

    Yeah, I've seen those dots before and it's the driver. You'll need the same version as a replacement, either from a donor DMM of the same vintage or a replacement panel/driver chip. Upgrading just the firmware in order to use a newer front panel/IC isn't possible that I'm aware of.

    There was a "light" version also, but it would be: Leichter Wehrmachtschlepper.

    German has variations on the word light (might want to call it nuances ;) ).

    «leicht» meaning light as in not heavy (-> a light meal)
    «licht» meaning light as in not dense (-> light hair growth)
    «Licht» meaning light as in illumination (-> light bulb)

    On the etymology of «Schlepper»

    The oldest source I could find on short notice tells me that "sleppa" is an old Norse word for honing / sanding. In the 12th/13th century (maybe earlier) «schleppen» carried over to the German linguistic usage for the act of sanding sth. (what later evolved into «schleifen») and the act of towing something heavy, thus "sanding the floor".
    One of the first nouns utilizing the new term was «Schleppe» -> chapel train, that long cloth/rag on a brides dress.
    So «Schlepper» means "the one doing the «Schlepperei»". :D

    That concludes my captain smarty-pants post of the day.

    Interesting how the word attached to a sanding method that fell out of use while the word didn't. The British Navy sanded the wooden decks of their ships with big blocks of stone called bears right into the 19th Century, though they had such heavy crews that they didn't need to tow it along the decks, which is how I'm guessing it got to be applied to towing something heavy. They had the sailors push smaller ones back and forth instead, I think (they didn't think many of the little details that I find so interesting worth writing down).

    in my case they are bass and treble controls, unforunatly i purchase the spline type instead of the D type, the knobs are 5 times the cost of the pot's so i will reorder them with some other bits on tuesday (bank holiday monday in the uk)

    That being said, here are some better pics of the gear now that I've schlepped it into the house.  There are several duplicates, in all but one case the second unit is a parts mule and not complete.  The counter side of both of the HP 8443A counter/tracking generators seem to be at least functional, though one is much more accurate.

    Yup! My effing memory is hopeless!  :-DD Lichtes/schwere.... there was a little schlepper, the Lorraine, that's it!  :palm:

    There was a "light" version also, but it would be: Leichter Wehrmachtschlepper.

    German has variations on the word light (might want to call it nuances ;) ).

    «leicht» meaning light as in not heavy (-> a light meal)
    «licht» meaning light as in not dense (-> light hair growth)
    «Licht» meaning light as in illumination (-> light bulb)

    On the etymology of «Schlepper»

    The oldest source I could find on short notice tells me that "sleppa" is an old Norse word for honing / sanding. In the 12th/13th century (maybe earlier) «schleppen» carried over to the German linguistic usage for the act of sanding sth. (what later evolved into «schleifen») and the act of towing something heavy, thus "sanding the floor".
    One of the first nouns utilizing the new term was «Schleppe» -> chapel train, that long cloth/rag on a brides dress.
    So «Schlepper» means "the one doing the «Schlepperei»". :D

    That concludes my captain smarty-pants post of the day.

    AWESOME!!  :-+ :-+ ;D

    Bearing bad news - «Etwas belastendes mitschleppen».
    In Finnish, the equivalent is pahanilmanlintu, or "bird of a bad weather".  They used to call bad news jobinpostia, "post from Job", a reference to the old testament in the bible.

    Closer to topic, Finnish still uses kuningas for King. The root for king is hypothesized to be kuningaz in proto-Germanic languages. The word that icorresponds to "boss" in Finnish is "pomo", from the Russian помощник (pomóšnik), which actually translates to assistant or helper. (Finnish is neither Germanic or Slavic language, by the way; these are both loan words.)

    Languages evolve weird, and I do not think linguists and etymologists have any kind of firm grasp on exactly how, yet. The twists and turns (especially single loan words) depend so much on the instant cultural situation (the context attached to the words at the moment of adoption?), and even individuals.

    I didn't buy anything today, too poor; but, I've noticed that ordering stuff from eBay (from China/Hong Kong to Finland, northern Europe) is much faster and very reliable using the "standard SpeedPak" shipping method. Thus far, less than ten orders though, they've all arrived within two weeks or so, with working tracking numbers, for a $2 - $2.50 shipping cost.

    I am, however, saving up to an Analog Discovery 2.  Cannot afford a good oscilloscope, but the AD2 should cover my actual needs quite well.

    P.S. While hardware looks pretty normal, but documentation not so decent. Just a bunch of files with schematics, citation of which FPGA pins connected to what, Verilog and VHDL examples, plus some descriptions in bad (even for me) English ("CLK50M ,from FPGA E1 input, you can use PLL get other frequency, for example 10M 25M 100M 200M etc. Have other don.t solder(PIN_M2), you can use a 5X7 volume Crystal oscillator solder on." and so on).

    A small indoor PTZ IP camera. If you're in the market for one I can recommend this: https://www.amazon.co.uk/gp/product/B075V3DFZP/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 (https://www.amazon.co.uk/gp/product/B075V3DFZP/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1) . Very handy for keeping an eye out for the delivery man (amongst other things!). It works well enough pointing through a window, but at night the IR light reflects from the glass so that needs be switched off. A sample still image taken just now taken through my 'office' window on a sunny May morning :)

    If this is not your house in the image, it is possible that you are not allowed to record it. Even still images might be a problem, which is the reason why Google street view has the possibility to blur images of a house, if the owner complains. But a video is even worse.

    Laws differ per country. You probably are not allowed to publish the footage or use it commercially or whatever but for private usage  :-//
    In our country you can register your camera with it's view with the police, if something happened they can ask for the footage so they might have a better chance of solving the crime. Only in severe situations ofcourse.
    In big cities there are many cameras now and in a tv show last year they showed a crime where streetrobbers stole a purse and drove off on a scooter.
    They could trace the streetrobbers throughout the city to the appartment building where they went in, they left their scooter outside.
    Police arrived and kicked the scooter so its alarm went off, out came one of the streetrobbers and he was arrested.
    Everybody is complaining about privacy but if these kind of crimes become obsolete because the criminals have no way to escape justice I think that is good.

    The laws in the UK are much less restrictive than in Germany. As long as you have informed your neighbours, had no complaints from them and done your best to restrict the coverage to your own property then you are good to go. You'd never get away with that in Germany.

    In our country the police told me a couple of weeks ago, during a house-to-house after a burglary down the street, that I could also leave them the connection details (IP address, userids, passwords) of my cameras so they could take a look whenever the need arises. Only with my permission of course. I was flabbergasted. And now I do wonder how many people actually give out these details.

    Sad thing that we so easily give up our (and other people's) freedom and privacy, because we're scared shitless for no good reason.

    Agreed  that is why I said 'record'

    Strangely enough the local police were not to concerned about my CCTV facing on to the public street opposite, when a major gangland double shooting and murder occurred just up the road. Indeed, they spotted it and asked me if I could provide recordings in a 2 hour window of the getaway car. They asked any householder in the area who had CCTV to provide what they could.

    I was more than happy to provide, despite knowing it was 2 hours of useless boring video, but they were looking for a particular vehicle and if even 3 frames in those hours of recording would help, they would help. I feel sorry for the plod who had to sit through hours and hours of this stuff.

    Another time the Police Complaints Commission turned up and asked me if I could provide any CCTV of the HMO (house of multiple occupation) opposite that had someone accusing the police of interfering with their violence and drug taking. Sadly my recordings only last 2 or 3 weeks and then get overwritten. I couldn't provide in that instance as the event was 2 months prior. But I do remember the incident and the arsehole going off on one.

    I also have a door-spy camera which is invaluable to totally ignore all the uninvited chuggers and salespeople that knock at least twice a day.

    ChrisLX200 has a very nice view compared to mine it has to be said.

    But even without CCTV we have curtain twitchers everywhere.

    I got one of the Xaomi Wiha screwdriver sets from Banggood and it came today.  Very nice value for the money.  There is a surprising amount of weight to the set.  I have other sets that are similar but don't have near the heft as this one.  I like the spring latch holding the tray in the case and the case will easily fit in the pocket.  The other nice feature is that the bit holder slots are magnetized.  No worries about having to re magnetize after a time.  The handle is narrow but it does feel good in hand.  The 'spinner' at the top spins very freely but is very smooth without any wobble to it.  I must admit that I got a bit of a tingle as I was fondling and playing with it when I got it out of the package.  I would love to have the big, ridiculously expensive 50 piece set but noe I can say that I have a set of Wiha screwdrivers ;D

    Arrived this afternoon - replacement stock of 4mm binding posts from China, and a pair of Schmitz carbide cutters from Germany. The cutters appear to be well finished - far more impressed by that than the finish on the Knipex cutters I received a few days ago. Whatever, both will do their job regardless of polish and fine grinding :)  These Schmitz cutters are smaller and more suitable for intricate PCB work, they are obviously going to be more delicate due to the narrow tips so must be treated with consideration. Photos taken with iPhone+DIY macro lens :)

    -25 DS1E-M-12DC relays, to repair a TDS684 (and a few others)

    - LED driver, because the IP rating on the orignal was a bad joke

    - 100V MOV, because I used a footprint for a 30V MOV going "yeah, I'll modify the P/N as soon as I get to the BOM". Cue fireworks.

    - Tube of LM324's because 'student proof' is another bad joke

    Nope. From Yiddish, actually.

    I thought both Middle High German and Yiddish had the word "s(c)hleppen" , it just goes to show how mixed we all are. Languages reflect migration and trade. Rather interestingly it isn't used much in my state.

    Philips pm5651 studio vits generator
    Panasonic HHSA500 D/A converter
    Shibasoku AS953b tv sound signal generator
    Astro VG828 digital video generator
    Philips PM5680 if generator
    And what looks like a home-built power supply....apparently actually made by Philips

    rigol DG1022Z. My first bit of rigol gear.

    not a bad little function generator. Did its thing I needed it for with no hassles.  the only thing that would have been nice would be a BNC to alligator clip lead in the package.. that would have been more useful than the bnc to bnc it came with.

    I wonder if the constant banner ad that's recently been up the top of the forum here is what swayed me?

    Another TI-68 for my little collection ;)
    This is the first model with the metal bezel and screws. The LCD had issues but after giving the flex connector some love (and 150°C), it looks like fresh from the factory.
    Paid 10,50€ for it and couldn't be any happier.

    I wouldn't call myself a collector. I just tend to fall in love with some calculators with alphanumeric display for some reason. Also bought an HP 42S recently but the display has very bad contrast.
    Anyway, the TI-68 is notorious for having issues with the flex connector and going over the PCB connection with a soldering iron at ~150°C tends to cure it without melting the connector.
    Worked for this one for sure. The display was barely readable with several columns and rows missing before:

    Cypress FX2/LP mini eval board (https://sigrok.org/wiki/Lcsoft_Mini_Board) (link is to Sigrok wiki page). For USB high speed transfer experiments: perhaps I could cobble together a 1 Msps 8-16 bit ADC with a differential front-end for measuring unipolar signals up to 12 volts (15 volts) or so. Would be quite useful for measuring supply glitches on SBCs, as I lack proper test equipment. The ADC would use the measurement ground, isolated from the FX2 using e.g. Si86xx digital isolators, so technically the ADC does not even need to have differential inputs. The FX2 itself uses USB host power and ground. Power for the ADC and its analog front end (voltage divider and buffer opamp, or an inamp with sub-unity gain) would be from a battery, to avoid the noise from an isolated DC-DC converter.

    Again, missing or weak columns/rows of the TI-68's display are usually caused by the flex connector and can be cured with a soldering iron at ~150°C.
    The display actually has a quite good contrast .. specifically for a matrix display of that period. The displays of e.g. the HP 42S and the TI 85 are barely readable in low light situations and/or under certain angles no matter what contrast setting you use and so you find yourself tweaking the settings all the time.

    I think I might have one of those TI-68 calculators. Seems like the display was badly discolored, but I haven't seen it in years.
    Again, missing or weak columns/rows of the TI-68's display are usually caused by the flex connector and can be cured with a soldering iron at ~150°C.
    The display actually has a quite good contrast .. specifically for a matrix display of that period. The displays of e.g. the HP 42S and the TI 85 are barely readable in low light situations and/or under certain angles no matter what contrast setting you use and so you find yourself tweaking the settings all the time.

    My screen is still in perfect working order ... still running off batteries from College too!  :o

    I actually got this last week, but one of the digits didn't light up. It took me until yesterday to get around to fixing it. I just wanted a basic calculator to keep by the living room computer with a display I could see in subdued light.


    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=436094;image)
    Yep, that's the big problem with LCD screens, hence my main calculator has LEDS nice, red glow and easy on the eyes.

    I forgot to add this photo of my TI-68 to my earlier post. The digits all work fine but there's a strange brownish discoloration across the bottom of the display. Whatever it is must be in or behind the clear plastic because it won't clean off.

    Based on the surface bubbling, Looks like the original thin plastic film is still on the display and needs to be removed.

    Edit, mine has a very faint brown tint too but none of the bubbling yours has.

    Yeah, it does look that way in the photo, but it's just dirt and grime accumulated in the corners. I checked carefully. I started to take it apart for more cleaning then changed my mind. I got all the screws out (apparently mine is the "rare" first version, later ones had no screws) and popped open the two bottom tabs and it still didn't want to come apart. So I just stopped before I caused any damage. It's been in storage for nearly 10 years so I obviously don't need it to look nice. That it still works is good enough.

    I was in the same boat: on the upper side above the display, the case just didn't want to come apart and it was a actually more of a pain in the you-know-what than with the later snap-fit case.
    At some point I just didn't care and pushed a little further and it just snapped apart without any damage. Did I mention all the keys fell out while I fiddled with that case construction?
    Again, in the snap-fit design of the later versions, the keys can't fall out since the PCB is held by heat-stamped pins - which of course that means that cleaning the keyboard isn't easily possible.

    oooh! I need an isolation transformer for my soon to come LISN.
    how much did these ones cost?

    I was looking at local prices, and it seems, watt for watt, it's actually cheaper to buy two 240/110 step down units and put them back to back than buy one proper 240V isolation transformer....

    300W unit was about 100 euros.
    1000W unit was about 200 euros.
    Both transformers are medical grade with shielding between primary and secondary. Also very low leakage from primary to secondary. Heavy stuff. The big one is 20kg so shipping was not so cheap.

    I get so angry at stupid sellers on ebay. Last weekend I buy a couple of memory modules to upgrade this old computer. Paid on Sunday, it was supposed to mail out the next day and should have arrived on Thursday.

    They didn't mail the package until Thursday.

    It showed up today. Two bare sticks of RAM wrapped in a layer of paper stuck to a piece of cardboard with two inch wide cellophane tape mailed in an envelope lined with plastic bubbles. So much for antistatic packaging.  |O

    They were cheap though, so I guess I'll keep them and see if they work.

    A friend bought a i7 processor (or similar, can’t remember which one) from someone on eBay. It was in a ziplock bag inside an envelope.

    When it went through the automated sorting system at the post distribution Centre it made lots of dents in the bag and envelope. They contacted the seller who thought he had done nothing wrong packaging it that way...

    They had lots of motherboards, processors and other computer parts for sale and the description sounded like someone with a clue wrote it, so it’s not some Neanderthal ripping computers apart.

    Be careful. I had two nice step-down transformers with my cash out (US$15 each) at the register recently but was  reminded that they might be auto-transformers. A quick meter check saved me some bucks.

    From other's experiences I suspect that most transformers marketed specifically for mains conversion are auto-transformers to reduce cost. Anyone know?

    Wow, the AP letter sortation machines move at insane speeds, and if you put something like a usb stick in a normal envelope it will literally rip it out of the envelope and shred it! if you want to send small items as a letter, it needs to go into something like a PM0 or PB1 bag which wont be destroyed by the sortation machines.

    It's a miracle you got it!

    Sometimes you need to set the device up for remote commands or just set it up. Many modern devices are very lenient, but older units can be more finicky about what they expect in what order.

    I got my answer from Astronics, (they bought the Ascor line from Gigatronics) with the following information for my apparently older version of this series.
    The interface is VERY easy. The GPIB commands simply set some parallel port bits for the relay drivers.
    I'll copy it here in case someone else needs this info:

    Programming Notes:
    ------------------

    A care has to be taken when a switch is connected or disconnected
    that shares a port number with another switch.  When switches share
    a port, programming one switch to connect or disconnect may also
    disconnect the other switch or switches on the same port.

    For instance, if you have a switch attached to J4 is in Pos 1 and want
    to also close a switch attached to J3 to Pos 2, you will issue the
    following SCPI command:
    SOURCE:DATA:PORT1 33

         32 for J3 Pos 2 on port 1
       +  1 for J4 Pos 1 on port 1
       ----
         33 program value

    Similarly if you want to just open J3 Pos 2 but keep the connection
    to J4 Pos 1, issue the following SCPI command:
    SOURCE:DATA:PORT1 1

          0 for J3 All Open
       +  1 for J4 Pos 1 on port 1
       ----
          1 program value


    Not all switch positions are available for a particular switch.
    For 1x4 switches use positions 1 through 4 only.

    A few weeks ago I bought a couple of monitor mounts. One for the desk, one for the wall. I haven't opened the wall mount yet, but tonight I set up the desk mount. This one, assuming it holds up (and I can't imagine how it could break), I can recommend:

    https://www.amazon.com/WALI-Single-Monitor-Adjustable-Capacity/dp/B018MT6ZEK/ (https://www.amazon.com/WALI-Single-Monitor-Adjustable-Capacity/dp/B018MT6ZEK/)

    I didn't use the entire clamp mount, only the upper part of the bracket part, which I bolted to the side of the desk through some drilled holes, but that clamp assembly is made from steel that's over 4mm thick. The only plastic I found was some bushings (I think they're plastic), wiring clips, and a few decorative parts. The design is well thought out and everything you need is included. They even include clips for storing the hex tools provided to assemble and adjust it. It's very, very solid and well worth the price, I think. The only adjustment of any difficulty is rotation, but the monitor bracket slides on and off easily, so it shouldn't be too bad if it ever needs to be changed.

    an old fluke nettool device ... these are from 2000-2001 and around.
    nice for checking cable length, and cable wiring.
    they seems to check also some basic features of the network (dhcp, protocols, ) but it seems mine is very weak at this.
    it is only made for 10/100bT networks, but I thought it could still work on gigabit switches.

    if anyone has this device, can you please test your's on a gigabit switch to see if it detects something or not ?
    the auto sensing of cables on modern switches must be mistaking the device. I would like to know. TIA.

    I got some of this delivered today.
    I've tried a few of the colours and it seems like it's all good wire, especially for the price of it! I use it for breadboards and it is much better than the pre-cut "jumper wires" I've gotten from elsewhere! The other stuff is more PVC wire coating than "wire", a couple of strands at most! This stuff is much better and a decent single strand! I would highly recommend it for anyone who does a lot of bread-boarding stuff!

    A couple of metal spudgers! (TE-03, "PRofessional".)

    I wanted to open one or two LED lamps, to see if I can reuse the Al-backed LED board in my floor/reading lamp conversion project. Without a spudger, I completely destroyed the first one in frustration, ripping the plastic bits (with various tools) into tiny little bits. Looked more like a rabid weasel on speed had had a chew at it... Pity. The lens assembly was nice, but now I have no way of positioning it correctly.

    Oh, and if CopperCone can't think of a use for a coppery cone, he should change his name! Where is he?

    On topic, a poorly HP3455A turned up today. Thanks to one of the members here I'm pretty sure where the problem is, so will soon be dismantling and displaying the innards for all to see. I'm going to need a bigger bench first, though. It's ma-hoo-ssive.

    Lamp Bases? Are they actually copper? Think of the cleaning before buying  ;)


    I don't think they are solid copper, but it appears they are at least copper coated (hence the "coppery" description). They are metal.

    They probably are copper, they've been  formed by spinning and there's only a few metals you can do that with... https://duckduckgo.com/?q=spinning+copper&ia=videos (https://duckduckgo.com/?q=spinning+copper&ia=videos)

    I see your sucky screwdriver and raise you three pliers that suck. Arrived today.

    Actually, suction pliers. For pulling on things like tablet/phone glued-on screen glass.
    $2 each.
    https://www.aliexpress.com/item/2017-Newest-Plastic-Strong-Suction-Cup-Clamp-Cellphone-LCD-Screen-Removal-Opening-Pliers-Repair-Tool-For/32814187852.html (https://www.aliexpress.com/item/2017-Newest-Plastic-Strong-Suction-Cup-Clamp-Cellphone-LCD-Screen-Removal-Opening-Pliers-Repair-Tool-For/32814187852.html)

    Edit to add:
    Actually the suction pads are rather nice in themselves. They have M4 x 8mm long steel screw mounts and are molded of a good tough clear plastic (PVC?) with very smooth front face. So they work very well, and could be used for all kinds of things. I hope I can find somewhere to buy these by themselves.
    Also the pliers have the suction pads on swivel mounts, so you can use them to grab onto a flat surface.

    PS @Free_WiFi  you know you can edit posts, right?

    Dropped by HALTED to see if they put any new stuff out on the Dollar Cart. I stopped to look at something near the door and John says "I got what you want!"

    He puts two boxes/crates on the counter that were ready to go to The Cart.

    FIRST DIBS!

    Thirty-one items today. I forget what they cost.

    10x AT91SAM7S256 Atmel/μChip ARM7 256KB Flash, 64KB RAM, QFN-64 (thanks Screaming Circuits)
    5x AT91SAM7X256 Atmel/μChip ARM7 256KB Flash, 64KB RAM, QFP-100

    22x ULN2803ADWG4 50V, 500mA Darlington Transistor Arrays (x8), SOICW-18.
    About 10 items are inductors, mostly of the power type
    45x PCF8563T/F4.118 More RTCs, I2C, SOIC-8.
    13x MAX3421EEHJ+ USB Peripheral/Host Controller with SPI Interface, TQFP-32. Sorta' like an FT232 with an SPI interface instead of a UART. I like these.

    10x CAT9534 (PCA9534 clone) 8-bit I2C and SMBus I/O Port with Interrupt, TSSOP-16.
    10x PCA9535D 16-bit I2C-bus and SMBus, low power I/O port with interrupt, SOICW-24.
    Because you can never have too much I/O.

    Ow, that's painful. A lot of storage space you just killed, a majority of missing values, and three different sizes so it doesn't help you standardize on one size in projects. Plus some values have multiple reels.
    Still, it's better than my couple of big boxes of mini-MELF resistors in reels, mostly non-standard values.
    Now you'll wonder if you should buy more reels, to fill in the missing table cells.

    Maybe you could just de-reel all of them into one tub, and use the resulting 'sand' as cat litter? Or practical joke props. What's it like to discover your bed is full of surface mount resistors?

    Speaking of forks-spades, does anyboy know of a reasonably good crimping tool for them that doesen't cost more than the instrument and the forks together, like the Swiss beauty recommended in Metrology forum that's for rich people ;) ?

    Interesting about forks-spades.
    When I was young, "spade" normally referred to the "fork" type in Australia, but over time "spade" has come to mean the automotive type connectors with the flat rectangular tongue to fit into a matching female connector

    Thanks for sharing.

    I will give this Chem Wik stuff a try and see how I go. If it's not reliable i'll give your stuff a try.
    In fact I will order a roll anyways on the strength of a recommendation. Which 1 do you use? I see it prices from around £5 right up to £20?
    I am still trying different ones trying to find 1 to stick with. As you'll know it's handy stuff for a quick couple of joints that need de-soldered or whatever. The Chinese stuff is a complete hit or miss even using a decent flux with it. I suppose you get what you pay for the same as everything else.

    1.5 and 2.5mm for testing purposes the small rolls are fine, 10m is £13 ish from rapid electronics (also listed in there ebay shop)

    Flow a bit of fresh solder into the joint then wick it away, a dab of a flux pen on smd's helps with the wicking under the chip

    Cool, thanks for the tip too. I'll order some up and see how I go with it. Hopefully I'll find one that works good for me from the couple I am going to try out.

    It's the Chem Wik one I have now so that may be good enough. I have heard others saying it is ok too, that's what made me pick that particular brand to try. We'll see. I'll message back here once I've used it.

    Just bought a 2nd hand HP N40L MicroServer from Gumtree as spare parts for my N36L which suffered a power supply failure yesterday. It also came with 8GB of ram so my M36L got a ram upgrade as well as a new PSU.  :-+

    it required a full teardown and significant dust removal on the workbench 1st! I also tore down the PSU and cleaned it plus lubed the fan to ensure it doesnt die too (fan fail is what killed the original).

    but now my server is back up and running!

    I've already had to order a Noctua NF-A4x10 40mm fan (https://noctua.at/en/nf-a4x10-flx) to replace it tho because the OEM fan is insanely loud, the old N36L fan was never this noisy (my server lives in my study)!  :palm:

    Those are surprisingly capable and useful little computers. I have two, an N54L running FreeNAS and an N36L with WHS (which spends most of it time turned off these days). I haven't had any trouble with the '54 but the power supply fan in the '36 developed a very loud whine after a few years. I've kept it quiet by oiling it every year or so. I bought a replacement fan last time, but as long as oiling continues to work I'll save the fan.

    They sure are! Mine was running WHS2011 but recently got a Samsung EVO 850 120GB SSD System drive which I installed 2012 Essentials on - I was surprised to find the network performance of 2012 is radically improved over WHS with regular transfer speeds well above 100 MB/s from my Raid5 Array (P410 controller w/ 512MB BBWC & 4x 3TB WD Red HDD's). Mines Primarily a File Server with a few light duty apps installed (SABNZBD, Sonarr, Radarr, PVO Integration service).

    My other Server is a Core 2 Quad Q9550 powered SFF PC running ubuntu hosting my Plex Media Server.

    bsudbrink is right! It is called »Feuerzange« - a utensil for preparing »Feuerzangenbowle«

    »Feuerzangenbowle« is usually prepared in autumn / winter, when it is cold, wet and dark outside.

    You take a pot, fill it with a dry red wine, season it with sliced oranges and lemon, cinnamon sticks, star anise and cloves, then warm it up on the stove (do not cook!).

    The most important part: Invite a lot of friends!

    Finally, when everyone is gathered around, take your »Feuerzange«, put it over the pot, place a »Zuckerhut« (sugar loaf, lit. "sugar hat") on top, pour some rum - at least 54% alc. (100° proof and above) and light the rum on fire. 80% rum will give you the best result in regard to caramelization of the sugar!
    While the sugar slowly caramelizes and melts away, keep on pouring rum with a scoop if necessary, enjoy watching the flames and have a splendid time anticipating the finalization of the »Bowle« together with your friends.

    When the sugar has completely melted away, fill into cups and pass it to your friends.

    Fun fact: The »Zuckerhut« has been the defacto standard for trading sugar from medieval times up until the 19th / early 20th century.

    I was in Germany (Kaiserslautern) many many years ago (cold war era) at Christmas time.  Our hosts did this using a grate (almost exactly like an eight inch cooling fan finger guard) over the bowl and the cone standing up.  Later we went to a pub and there they did it with the cone on its side.

    At the cost of a new set of cosmetics or a new handbag? :-DD

    Believe it or not, no.  She is always finding things on Swip-Swop that she thinks I might like and shows them to me.  This was the first time that it was something I actually and a want/need for and was interested in.  Then there was the time she bought me a band saw from a local garage sale.  I ended up giving that to my son for a small woodworking side business he was putting together and had more use for it than me.  He lives about an hour away so I have access to it if necessary.  She never asks for anything but I make sure her wants get taken care of also.  She is also simple to please.  A bag of Chester's hot fries goes a long way :-DD

    Christmas time is fun.  When she asks, I give her a list of things I want.  After saying, what the hell is that, and that, and THAT!  And shaking her head, she now has a list.  She does the same for me but at least I know what it is she wants.  The facial expressions are pure gold.

    1.) ESD mat
    Why? Due to clever ventilation of my basement lab the general humidity level is dropping
    in summer from over 85% relative to around 55 % relative, thus necessitating a this ESD mat.
    By clever ventilation I mean: open all basement windows when the absolute humidity
    outside is lower than the absolute humidity inside.

    2.) RJ45 Clips
    Why? When encountering in the field any cables with broken off clips, I always replace
    these cables immediately for reliability reasons. However, sometimes I do not have the
    right cable length at hand. I then fit these RJ45 cable clips and later on replace the thusly
    repaired cable the next time I turn up at the site since utmost reliability is very important to me.
    Refitting a RJ45 plug on a patch cable in the field is too difficult. I sometimes refit RJ45 plugs
    in the lab for use by myself. Even so, I find industrially made cables with RJ45 plugs
    significantly more reliable.

    Only indirectly electronics related but I just bought a Husqvarna 562xp chainsaw with a 24" bar.  My trusty Stihl 250 is just not up to the task of bucking out some of the larger trees down on my property.

    I almost bought the next model down - the "555" - which has a nice electronics meme model number - but in the end decided to put up another $100 and get a professional saw.

    I've been hesitant to buy one of these newer saws with electronically tuned carbs. The Husky "Autotune" and Stihl "M-tronic" systems have been out for a few years now. The long term reliability of electronics is a virbrating, sawdust, dirt, oil and gas exposed saw is suspect IMO. We'll see.

    It would be nice if they made the Autotune software available and usable for non-dealers to use the diagnostics and and do firmware updates etc... >:(

    Would love to hear if anyone has done any tinkering with these.  I'm sure someone on this forum has the skills to hack into the electronics on these.

    Snap !

    Well guess what, my youngest just bought the same model today. His 288 packed up and TBH for what he mostly does a bit smaller saw will be better. Now I can get my 359 back !  :)

    How's your one going ?
    Oh and yes I haven't forgotten our discussion about these but haven't seen the guy as we're both pretty busy. He bought it from my friend and got strict instruction to use best oils at NOT lean rates and ensure the air filter is kept clean. Not doing so bluffs the carb into leaning out the mix at the risk of seizing the saw.  :rant:
    So this ol' fella needs to get up to speed on these Autotune saws.  :scared:

    Great so far. The real test will come later this summer when i buck out several winter downed trees on my property.

    Thanks for the videos. I ‘d seen the longer one when I was researching the saw. The electronics geek side of me would love to get a hold of that software for tinkering and future repairs, but the old school two-stroke mechanic side of me just wishes for a simple, no electronics, traditionally aspirated and easy to repair/rebuild saw.

    Just got my hands on some old LMT gear (german manufacturer). One is a  Current meter, apparently for some photodiode heads (which I don't have) and a "colormeter".
    The units feel kind of like they were made in a barn somewhere,  held together with some screws and some prayers. But they lasted this long, so...

    The current meter version I have goes to 10e-11 (at least that's what the specs say) but I have yet to measure something. Cap leakage tests, anyone?  :popcorn:

    Yeah I know, me too.
    AFAIK all the bigger saws still have carby's.
    They are this way to meet various antipollution requirements all over the world as that 'newish' air scavenge system to the muffler needs a lean exhaust gasses to do the after burn in the muffler.
    But a chainsaw that needs to be 'green',  ::) they cut down trees FFS !  :palm:

    I got these delivered today!

    I decided to give the Diamond sharpener a go as opposed to the usual whetstone.

    I also decided to give the Chem Wik a try as i have been using the 5 rolls for £3 stuff from China with mixed results! I will report the success or failure of both products later today!

    So I have used the Diamond sharpener to tidy up and sharpen a few of my different knives now and I am well impressed!
    I found it was awesome for sharpening smaller lightweight blades that I use around my bench and the house that weren't in too bad shape before I started. They more or less just needed the edge already on them tidied and sharpened up a little. I think it is fine for removing small burrs and dents on smaller blades but if you were talking about axe's and proper 12" outdoor knives you'd need a bigger more substantial sharpener.
    The biggest hobby blade I sharpened was a 6" lock back that was in ok shape before I started and it is now razor sharp again. I also re-edged and sharpened my swiss-army knife with both a 1-1/2" and a 2-1/2" blades on it which are both also razor sharp again and I have a small 2-1/2" utility type blade which is sharpened to perfection again.
    All of these were in ok shape before I started.
    I gave one of the 12" kitchen knives a quick going over but this also was in great shape before I started so it is hard to say if I improved it any.

    Verdict.
               
    Ideal for smaller blades that are not to bent out of shape or bigger blades that only need a couple of passes to re-sharpen. It does do what it's supposed to do with very little effort. It's quite impressive when you see it working as it's very lightweight and it is steel blades it's sharpening.
    For just a few quid you can't go wrong!

    I would recommend this item to have in your drawer or bag if you use small knives at all.

    Cool! I have the same phone (bought it used though). Only thing that I do not like about it: The main camera module stopped working.

    Purchased yesterday.
    Cat S60 smartphone with Flir thermal camera - NZD 1099
    It will not be used as a phone, just a thermal camera in the workshop with the ability to email the images.
    First image taken is of my little girl...

    Cool! I have the same phone (bought it used though). Only thing that I do not like about it: The main camera module stopped working.

    Despite the connector is a USB-A, they are passive adapters that do not work on the vast majority of PS/2 peripherals - only if the peripheral itself has internal circuitry that performs the dual USB/PS/2 protocol.

    At any rate, the machines I have still feature the PS/2 ports.

    Yes, PS/2 is a serial port; however, it is different than TIA/EIA-232-F in voltage levels and data communications. To convert between the two, some circuit is required.

    Isn't it the other way around? The USB driver/chipset in the PC has to support the legacy PS/2 protocol. The PS/2 mice I've used with these adapters were all designed well before USB was around. In the other direction (forcing a USB mouse into PS/2 mode) requires the USB mouse to support PS/2 mode.

    Yes, $10. Yes, I picked it up. And yes, it is the real thing, not just a picture.

    Of course I'll have to do a separate thread about it, with heaps of photo, and pictures once it's set up and working.

    Oh! And this polysomnograph, nearly forgot about it with the excitement of the microscope. Unfortunately without a chart recorder. But all the manuals for all the different amplifiers.

    I don't recall seeing a PC whose USB ports would recognize a PS/2 peripheral via this passive adapter, but I couldn't possibly know all the systems.

    What I remember is the transitional period when the "hybrid" mouse would be fitted with a PS/2 connector so it could be used with older PCs as well - after all, the new models of mice would need to be useful in a broad range of systems, especially in the early days where BIOS did not support USB peripherals.

    My "half knowledge" comes from a project I did a few years back to allow PS/2 and PS/2 compatible USB mice to connect to an 8-bit computer joystick port (For the Amstrad CPC range). If basic USB mice are connected to it they are recognised and configured to PS/2 mode. This was done by sending a series of commands to force the mouse into PS/2 mode during initialisation.

    On the PC side, my old PC (WinXP) had a PS/2 mouse connected via one of those adapters to the USB port and worked fine for many years with several different mice.

    Here's a picture (prototype) of the CPC device I designed. There were two versions, one with a PS/2 socket, the other (below) with a USB socket.

    There are probably all sorts of other uses to put those units to. The EMG for recording muscle twitches must be a pretty sensitive amplifier, and then you have airflow sensors and piezo ones to detect chest-wall movement. The amplifiers should all be isolated, too. Nice find! I bet some of the interiors are worth a looky.

    I mentioned this somewhere around here; I really liked Logitech's trackball marble but I started to develop fatigue on my thumb muscles and had to stop using it. Minesweeper on Windows 3.11 was one of the reasons for this.

    I remember you saying so.
    Isn't a marble the one with the ball in the middle ?
    I looked at those and immediately thought they would cause RSI whereas the ones with the ball on the side where it can only be used with your thumb and the ergonomic shape allows you to 'rest' your arm when your hand is planted on it. We really like these and would replace them in an instant should they ever stop working.
    A buddy I convinced to get the wireless Trackball can't believe he got used to it so quickly and it was the perfect solution for using a mouse on the armrest of his recliner where he uses his 48" PnP TV as a monitor too.

    Both of mine are RS-232 over a PS/2 connector.

    My current main board has PS/2 connectors for keyboard and mouse, but I also have the right USB adapters as well.

    I've had that kind of trackball mouse before and also the torpedo type with the ball on top. Beautifully made and feels nice to touch. I got because desk space was tight for conventional mouse, but found them pigs to work with so went back to to standard mouse again.

    A scanning electron microscope, complete with what appears to be complete schematics, for $10.
    Yes, $10. Yes, I picked it up. And yes, it is the real thing, not just a picture.

    Of course I'll have to do a separate thread about it, with heaps of photo, and pictures once it's set up and working.

    Woah! :o Looking forward to that thread.

    What will be the first thing you "scan" in it?

    Dug up a box of 25 Hirose connectors I got on eBay about 10 years ago.

    The connectors retail for $45 or so at Element 14, but I found 25 of them for about $50 for the lot.

    Finally got around to soldering one up to my prototype last night.

    Strictly it was brought yesterday in an on-line auction from what was, prior to Philips pulling out of the UK, a fully functioning research lab so it should be ok and calibrated but time will tell on that one when I get the OK to drive to Cambridge and pick it from the lab.

    If your tight for room even make a Perspex jacket to go over the unit with the soft plastic case. You can either glue or screw the edges together. Either way it really doesn't cost much ££'s and is VERY strong! Also if your neat with your cuts etc you can make a clear see through jacket for it so you can see the internals or a colour to suit the rest of the unit. You'll get the Perspex from any craft shop or places like that.

    Chances are that it will perfect when I go and collect it, it was after all in a working high class lab, its just me possibly over reacting after discovering to my shock that such big piece of equipment in a plastic shell unlike all of my other CRO's which are in nice metal cases and strong as fuck. I just never expected that something as big and old as that would be in plastic enclosure whereas all the more modern scopes are similar on size to a ghetto blaster and plastic is perfectly suited to that size, but the 3390B is 391 x 147 x 551mm, its even bigger than my HP1740A and that weighs a bloody ton.

    The oldest source I could find on short notice tells me that "sleppa" is an old Norse word for honing / sanding. In the 12th/13th century (maybe earlier) «schleppen» carried over to the German linguistic usage for the act of sanding sth. (what later evolved into «schleifen») and the act of towing something heavy, thus "sanding the floor".

    Interesting how the word attached to a sanding method that fell out of use while the word didn't.
    Well, Danish has "slibe" and "slæbe"...

    I may be mistaken, but I believe that the 'not calibrated - display only' sticker isn't meant to indicate that the meter is out of calibration, but rather is there in place of a normal 'calibrated on/calibration required on XX date' label normally used to track cal history to note that it's being used in a non critical application and that periodic calibration is not needed.  That lets the folks who go around a facility rounding up instruments when the calibration company makes its visits know that instruments so marked don't need to be looked at and can stay where they are.

    Yep. I've got a Fluke meter of the same line, an 8842A - who knows when it was last officially calibrated and who cares.  It's fast, stable  and dead on accurate based on comparison to my DMM check and semi recently calibrated HP 3478A.

    Well I didn't know that what's the sticker meant, I thought it was a warning that it  had been checked and found to be needing calibration. Good job the seller didn't know that then, in fact they didn't know anything about it apart from what they had been sold for on Ebay and they quoted me 150 to 300 USD. I found one that sold as working for only 60USD and told the seller that unlike theirs, it was photographed working. As they couldn't power it up to prove it was OK, I offered a price for spares or repair and was accepted.

    As I wasn't in need of another, already have sufficient so I was fully prepared to walk away from the deal if they said no. [emoji41]

    In our lab (and several others I've worked in), "not colibrated, indicator only" doesn't mean it's out of calibration. We have devices that get regular calibration, but don't want the expense of calibrating all instruments. However, the "non-calibrated" devices are checked against calibrated ones on a regular basis to make sure that they are within range, the only difference with the "non-calibrated" devices is that there is no verifiable calibration paper-trail.

    Post by: CatalinaWOW on June 11, 2018, 03:42:03 pm
    I agree that the not calibrated sticker only means that the unit is not on the normal calibration schedule.  I have worked at places where it also means that the only time it will be checked against other instruments is if the readings are so whacky that the person using it can't believe what they are seeing.

    So if you are buying, a sticker like this should be interpreted as "probably not terribly wrong".

    When I first read that, I thought it referred to Donald Trump's position on meeting with Kim Jong Un

    President Donald Trump says he's "totally prepared to walk away" if his meeting with North Korean leader Kim Jong Un is not productive.

    I get to collect my Fluke 3390B tomorrow so I'll be posting some pics of it later, my first foray into the world of digital scopes apart from a DSO138 which many consider a toy but is really a pretty useful but basic digital scope with a stupidly low band width but good for checking if clock pulses etc are there and does provide rudimentary cursors and automatic measurements etc, especially handy as a floating scope.

    It can be wired as a single pole, triple throw switch, like the ones with the rotating knob, but with a lever.
    Quite useful back in the days, when you wanted to avoid additional electronics to emulate this behaviour with the more common ON-OFF-ON switch.

    Common is middle pin of upper switch. Connect left pin of upper switch to middle of lower.
    Pole 1 is left pin of lower switch,
    Pole 2 is right pin of lower switch,
    Pole 3 is right pin of uppser switch

    Arrived today. Both pass self test without problems but 33220A have some problems with rotary encoder. Seems that im not only one who have those: http://www.dasarodesigns.com/projects/cleaning-the-encoders-in-agilent-33220a-function-generators/ (http://www.dasarodesigns.com/projects/cleaning-the-encoders-in-agilent-33220a-function-generators/)

    320€ totally posted to home. Not bad.
    Wow, that's a great price. Just a 34401A can cost a lot more than both of these.
    i agree, it was good deal.

    Funny was that i was she was selling Agilent Power Supply that i bought from her for 120€. Well, there was a mistake and she didn't know that there was multiple different units and she had picture from wrong unit. Did see that before shipping and did say that actually she was selling 34401A and do i still want it for 120€. For sure i agreed. And then i asked if she has some more and there was still this 33220A that i agreed to buy for 200€

    Really impressed with this seller of COB LEDs. They have some unique designs, its mostly car oriented (12V rating) but they have lower voltage as well.
    For 12V its about 9-11V across the LEDs depending on color, then the 3V ones are 1.9-2V or so. For the 12V I just used a resistor, for the 3V would need a small current regulated dc-dc ideally.

    Don't get the triangular red/yellow LEDs yet, they appear to be rejects as one or two LEDs are not lit (still works OK though, as they are in parallel).

    In the auction where I won that Fluke 3390B, there was also a Keithley 220 and 230 and I almost went for them but decided against because of their size and once I calibrated my meters etc, they would be gathering dust.

    Analog Discovery 2! (Digilent Inc. documentation (https://reference.digilentinc.com/reference/instrumentation/analog-discovery-2/start))

    I was saving up to a benchtop oscilloscope, but realized I could not afford that and differential probes.  I want to do differential measurements, to characterize power supplies I can use with SBCs like Odroid HC1 that require a well-regulated 5V supply.  (They're very finicky, and if you use a spinning-disk HDD, they also require quite a lot of current.) The 100 Msps definitely suffices for me for now, as does the ±25V analog and ±5V digital signal range.  I'm also working on some microcontroller projects, including one scientific one, interfacing to pressure and PT100 temperature sensors in an experiment. I've needed tools to examine e.g. power rail noise, since the sensors are quite sensitive; I'm hoping the AD2 will help.

    Well, keep your eyes peeled for companies pulling out the UK because of the forthcoming Brexit, thats how I got this one. Philips are pulling out of UK and moving into Europe and just getting auction houses to clear out their old premises. This came from a working Lab and they had about 6 of these, mixed between 100MHz and 200MHz, the others were 4 channels which I prefered TBH but they rapidly rose to dizzy prices. This little 2 channel chappy started off low in the pre auction bids and I was a little worried if everyone else had been to site and knew something I didn't. I however went for it and it went for a low price + buyers premium and VAT. However, as it turns out I had nothing to worry about, its fine.

    It isn't differential input but the BNC adapter (https://store.digilentinc.com/bnc-adapter-board-for-the-analog-discovery/) for the Analog Discovery is a useful addition. Increases bandwidth for the scope + signal generator functions and lets you use regular scope probes. The digital I/O lines are passed straight through. I'd recommend getting some jumpers with the long tabs though as the 0/50 Ohm impedance selection jumpers on the adapter are a bit annoying to pull out.

    A new radiator for my car, and an oil change.

    the poor thing totally blew up while coming up a hill on the way home on Tuesday night.. radiator had ruptured and the first I saw of it was the engine acting weird, and a few extra noises, then I saw the temperature was way up, and when I looked back in the rear view mirror a whole bunch of white "smoke" following me up the hill... when I stopped the car and opened the bonnet, it was like a cartoon car breakdown. thick steam pouring up into the sky.

    Anyway... after arranging to get it towed to my mechanic, the mechanic said he expected the engine was dead, and since this is my crappy little cheap runabout, that would mean goodbye, and back to the 2nd-hand runabout lottery to find a replacement. I was a bit sad about that as this car has actually been a great little reliable machine.

    So I'm really happy to hear that somehow the engine survived its cooking, and my daggy little 1999 corolla hatch can keep pottering up and down the hill between my house and office for a while yet.

    Yup, you got a score there for sure!

    Any of the things I have had any interest in at the auctions ends up going for too much £££'s. I'll just keep watching like you say though and i'm sure 1 will turn out in my favour sometime.
    That's the thing with the actions, you get the item itself for a decent price but when you add auction fees and taxes then shipping it can get to eye watering numbers quite fast!
    It's hard to stop when you start bidding up. I always think …. right..... when it gets to X amount i'll give out but always end up going over at least a little bit.

    Thanks I will, I agree, the jumps in price are small in this type of auction and when you reach your limit and a another bid arrives you nearly always go on another couple of bids. Reality is different when add in the fees, they become bigger steps than you thought.

    Shipping on this auction wasn't an option, collection was mandatory and by appointment so that I think limits the prices a bit.

    Something will turn up in the end, I was just lucky 1st time around and that's unusual for me.

    I do not give in to the temptation of 'just one more bid'  It even surprises SWMBO at my self control.  I buy the occasional diecast car off of evilBay for my collection and I have lost a bid for pennies because I do set a hard limit so I don't get caught up in the 'just one more bid' syndrome and end up paying more than what it is worth.  On TME, I look for stuff with a make offer button.  If my offer is accepted, great.  If the counter offer is acceptable, great.  Otherwise, I walk away to buy another day.

    Thats great and amazing self control, but sometimes I have been waiting for so long to find something and I mean a long time, that I really don't want to wait that long again if there is a slight chance that a small tweak to my bid could win it. In other words, I don't have your self control, I get a bit impatient and just go for it until it gets to a point beyond which I just don't go. Hmm thinking about it, I do have your control then, just that I set myself an ideal figure that I want to pay and a maximum if pushed.

    It isn't differential input but the BNC adapter (https://store.digilentinc.com/bnc-adapter-board-for-the-analog-discovery/) for the Analog Discovery is a useful addition.
    For now, I'll start by cobbling together a 2+2 4mm banana jack panel I can connect to the Analog Discovery 2, and use the two differential channels using cheap probes. I really only need sub-MHz bandwidth for now (for investigating power rail noise and glitches in various projects that have stalled due to lack of test and measurement equipment!), but I definitely need the differential probes.

    (A 16x2 (8x4) panel with standard separation between each pair would be even nicer; you would then get every pin on a banana jack. At a standard 0.75" grid, it'd be about 7" by 4"; might make a nice cover for the AD2.. Or maybe I could do a fanout from a short 34-pin ribbon cable?)

    If I was using a say Rigol DS1054z without true differential probes, just using two separate channels and display math to measure the voltage drop of a 0.01Ohm resistor at 5V, I would not get even one-ampere resolution (because 1A drops 0.01V over a 0.01Ohm resistor, and the scope resolution is at best 5V/256 ≃ 0.02V, 0.04V at ±5V range). What I would like to do, however, is measure and record the voltage drop over that resistor, and the 5V voltage itself, at say 100 kS/s to 1 MS/s continuously at maybe 0.05V and 10mA resolution, to see how each supply copes with different loads, as well as whether there are problematic glitches. And if glitches do occur, whether added bulk capacitance or a pi filter (on SBC input) fixes it.  I can do that with a Teensy 3.2 using my own circuit, but I didn't have anything to compare against and verify my circuit.

    If one of my ~$10 DC-DC modules with an inhibit pin can provide max. 6A at 5V continuously without glitches (as the current demand is quite variable, 1A to up to 6A in short spikes), I can finish my Odroid-HC1 microcontroller carrier project: a Teensy 3.2 microcontroller that can be used for serial console, external display controller (either a cheap small TFT or OLED, for status information), external GPIO (the HC1 has none!) for a couple of buttons etc., monitoring the current and voltage supplied, as well as turn the Odroid-HC1 (or C1+ or XU4) off and on at desired intervals, keeping just the microcontroller always powered on.

    It is amazing how hard some problems are, when you don't have good test and measurement tools!

    That's the thing with the actions, you get the item itself for a decent price but when you add auction fees and taxes then shipping it can get to eye watering numbers quite fast!
    It's hard to stop when you start bidding up. I always think …. right..... when it gets to X amount i'll give out but always end up going over at least a little bit.
    Enjoy your new toy!  ;D

    I do not give in to the temptation of 'just one more bid'  It even surprises SWMBO at my self control.  I buy the occasional diecast car off of evilBay for my collection and I have lost a bid for pennies because I do set a hard limit so I don't get caught up in the 'just one more bid' syndrome and end up paying more than what it is worth.  On TME, I look for stuff with a make offer button.  If my offer is accepted, great.  If the counter offer is acceptable, great.  Otherwise, I walk away to buy another day.
    Thats great and amazing self control, but sometimes I have been waiting for so long to find something and I mean a long time, that I really don't want to wait that long again if there is a slight chance that a small tweak to my bid could win it. In other words, I don't have your self control, I get a bit impatient and just go for it until it gets to a point beyond which I just don't go. Hmm thinking about it, I do have your control then, just that I set myself an ideal figure that I want to pay and a maximum if pushed.

    In my youth, I was the buzzard in the picture that said, patience my @ss, I'm gonna kill something.  Now that I am a greybeard, I am like the old bull.  When the young bull says lets run down and screw us a cow, the old bull says, let's walk down and screw them all.  :-DD

    This NAD 310 arrived yesterday. It is intended to be a back up for the amplifier in my living room computer/TV setup, but here it is in my small bedroom system to test it out. I had a Sherwood receiver in this system before, so I had to take the Denon tuner out of storage for testing. I may leave it this way for now.

    Replaced my 'Nicad' generation Hitachi cordless drill with a Makita Drill Driver (and angle grinder coming in a promo). For Aussies - watch the Bunnings version it includes a lower spec driver! $649 btw

    Why did I wait so long  :palm: Awesome amount of power now what to screw or drill first.

    Think that is about the pre EOFY Tax time $ spent  >:D

    5Ah pack is huge capacity, surprised it came with that.

    I used to have one of those Rat Shack equalizers back in the 80s.  Eventually it lost a channel, and while I poked and prodded at it a bit, I never really dug into it, and it eventually got tossed during a cleaning binge.  Shame I didn't keep it; I'd certainly be able to fix it these days.

    I bought mine used sometime around 1990 for $20 from a guy that worked in the local video rental shop. I have to confess, I've never used it as an equalizer. I just connect to the inputs so I can have the bouncing light display.

    I've thrown away lots of stuff I probably should have kept, but since I live in an apartment there's limits because of available space. Even now I have two big A/V receivers from the 80s and at least two DVD players out in the balcony closet. How they have survived the last few clean outs I have no idea.

It's a replacement for what the seller couldn't find, the AD7796 16-bit delta-sigma ADC for bridges and sensors (123 Hz max update rate) which would have been more immediately useful. Oh well.

    Of course, I had to add a couple more items for free shipping. This was one of them (also on sale):

    The other was a pair of socks.

    In finland you can find this kind of rag mats from allmost all the houses. i think we have maybe 10-15 of those (we also have that wood thing that you use for making those). Really traditional at Finland.

    Yeah my Ma was right into handcrafts and had a couple of weaving looms on which she made all sorts of mats, rugs and cloth. Rag mats had string warp and are very tough wearing. I have no idea where she got her inspiration from to start making them.

    I brought a USB hard drive caddy to house the 2TB drive I extracted a Sky + box which I had intended to use as in internal drive but Windows 10 does not like there but I works perfectly as a USB drive, so thats what's it going to be once the caddy arrives.

    A Tytera DM-380 DMR handheld transceiver for some mucking around with DMR (Digital Mobile Radio) - Amateur radio stuff - have a SharkRF openSpot UHF to ethernet 'dongle', with a bit of luck (and a  Wifi - ethernet gizmo) - should be able to get it to get my Tyt MD380 to link "UHF-Ethernet- WiFI - 4G - Internet" to other Amateur radio DMR 'reflectors'. There are several hundred I believe - ONCE I get it all lined up.  :scared:
    Have managed so far to get the HH transceiver to talk to my computer - you need to do this to start to program some of the 1000 channels.
    Some good resources on HamRadioWorkbench podcast and Adafruit to name a few - Thanks. :-+

    The Minimus 7 speakers just weren't doing the job with the NAD amp. They have their place, but as main speakers the bass is lacking. After a little looking around I ran across these Dayton Audio B652 speakers. I ordered a pair and they arrived this morning. I wasn't expecting too much, but all things considered, they are pretty impressive. I can honestly say they are the best $30 pair of speakers I've ever heard. I'd be happy at 4 times the price.

    At 70Hz, thats still not much in the way of bass is it, so what was you using before for these to be sounding so much better?

    Minimus 7 speakers from Radio Shack. The difference comes mostly from 6.5 inch vs. 4 inch "woofers". Believe me, there's a world of difference. If 70Hz is the spec on the Dayton speakers, then they are definitely not overstating the speakers performance.

    Yes, that increase in driver size would make it sound much better, spec and manual is attached.

    I have a set of the Minimus 7's for over 20 years and love them.  This, however, is certainly tempting enough just for the price itself.  Hard to believe that they are $30 USD for a pair with $7 shipping.

    I probably have a similar ammount of E361xAs, as you can never have enough DMMs, PSUs and oscilloscopes (and to a lesser degree all other test gear ;D). These E361xAs are great little PSUs and I quite often had situations where I needed  like -15V, -5V, +5V, +15V, +30V and +150V  to test some gear, so I used like 8 E361xAs to power it, (+150V from 3x E3617A in series)

    Killing some noise in my equipment. While Noctua fans are overpriced and always have had a ... unique ... color scheme.. They sure do run quiet and move a lot of air while doing so.


    Post-op report:

    Well, the new 80mm fan perfectly in my HP 54600B. It moves more air, while being so quiet I literally can't hear it. With the original fan, the HP was one of the loudest things in my room...

    But not THE loudest. That prize goes to my Tektronix PS280 power supply. This thing sounds like a 747. It uses a 60x60x20mm fan. I replaced it with a 60x60x25mm fan, and it does fit, if you remove the mounting bracket, and flip it around, giving you exactly 5mm more room, which is needed since the original fan sits flush against the outside case.

    Also needed to trim down the bracket mounting screws... No problem there.

    Old fan was hard-wired into the PCB. So I cut the original wires at the fan, tinned, attached a 2 wide header, tidied it up, and bam, pluggable fan header. New Noctua fan fit great.


    Upgrade successful! I can now hear myself think with all these instruments turned on...

    SPD3303X-E   Programmable Power Supply

    My former gear was over 20 years ago (20MHz CRT scope, 10MHz signal generator, PSU with analog display etc.). What a change  ;)

    (And no, I'm not in a GAS mood. I'm just renewing my stuff, trying to get good gear that will last me for a few decades if possible, and saving space).

    Thats a nice piece of kit you have there, the newest piece of major kit I have is a 20 years old combiscope and to compliment that I have other new kit that was sub £60 cost like LCR meters, voltage references, counters, pulse generators, USB microscopes, multimeters, function generators and bench power supplies.

    Now I'm asking me, how to operate that device because the documentation is a little bit confusing for me. And is it possible to take the DB9 <-> USB FTDI converter? I have already one here so i wouldn't need to buy one.

    It's quite easy to calibrate a 3478A once you have it working. Just need a voltage ref 1/3rd of the full scale on each dc range, a known dc current, some 0.1% resistors and follow the steps in the service manual.

    No.  The DB9 is TTL.  Do a search here for this.  Isolated USB adapters are available or you can make one.

    Now I'm asking me, how to operate that device because the documentation is a little bit confusing for me. And is it possible to take the DB9 <-> USB FTDI converter? I have already one here so i wouldn't need to buy one.

    No.  The DB9 is TTL.  Do a search here for this.  Isolated USB adapters are available or you can make one.

    Yes, i already saw the instructions for that, but that is too much fiddling, printing a board, get SMD components. Maybe there is some china-made adapters?

    Yeah, I have the benefit of living a train ride from Akihabara, so most of my kit is repaired surplus stuff from junk stores.
    My latest junk purchase is a $35 HP3478A that only needs a few things to make it fully functional.
    It's quite easy to calibrate a 3478A once you have it working. Just need a voltage ref 1/3rd of the full scale on each dc range, a known dc current, some 0.1% resistors and follow the steps in the service manual.

    From mobile device so predictive text might have struck again [emoji83]

    Yeah, I'll have to look into that. The calibration is still 'valid' in that the backup battery is still holding the RAM (I have a new battery to replace the old one with) and seems pretty spot on still, but it might be a fun project to recalibrate it.

    Thats the thing about 3478A's as long as the ram retains the data, they seem to be spot on, even years after the last documented calibration. :-+

    I bought the adapter directly from Maynuo, but at the same time as I bought the M9710, so they gave me a good price. You can buy it seperately for about €40. The nice case and the fact that it's from the OEM makes it worth more than some generic Chinese copy that wouldn't be much cheaper. https://www.ebay.de/itm/M133-USB-R232-Cable-for-MAYNUO-M9712-M9812-M9710-series/112442420163 (https://www.ebay.de/itm/M133-USB-R232-Cable-for-MAYNUO-M9712-M9812-M9710-series/112442420163)

    I don't think I've ever read the manual. If you have any experience using any other programmable loads, the M9710 is quite intuitive and easy to use without further information.

    You have the right idea...  A couple more hints:

    It's a device.  A peripheral, not an entire system.
    In common use through the 1970s, fell out of favor in the early 1980s.
    Some models could be converted to 50 cycle operation with a completely mechanical modification.

    Yes, it's an 8 inch floppy unit (2 drives).  glarsson wins 50 gray beard points.  For those interested, the vast majority of 8 inch floppy drives used +5 for the logic, +24 for the head stepper motor and AC wall current for the spindle motor.  The spindle motor uses a belt to drive the actual spindle pulley/flywheel.  In the case of Shugart drives, the spindle motor was 110/220 and the spindle pulley could be replaced for 50 or 60 cycle operation.

    The unit I'm repairing got heavy use as I prepared for my VCF East exhibit this year.  The AC cooling fan failed but I didn't notice until it was too late.  Fortunately, only the PS seemed to suffer for the lack of cooling.  At present, rather than repair the large heavy linear power supply, I'm replacing it with a switcher.  I use this drive in a number of exhibits and demonstrations each year, so the light little switcher will make it easier to move around.  I'm sure I will diagnose and repair the linear PS at some point.  The dead fan, on the other hand, is already pitched.

    A stainless Bialetti "two cup" coffee maker. The aluminium version that served me for many, many years has become a bit tired and I had run out of rubber seals that also needed replacing, so I thought I'd treat myself to a stainless version. Though I'm not entirely sure about the link between aluminium foodware and degenerative brain diseases some people insist exists, eliminating it from the kitchen won't hurt.

    I hadn't expected it to be actually much quicker than the old version. If you use water from the kettle that just boiled, as is advisable with these things, coffee almost immediately starts flowing from the spout after putting it on the stove. The old one would take a few minutes to get there. The tight manufacturing tolerances even lead to minor issues. The metal on metal seal the filter makes is tight enough to build pressure, so just putting in hot water and the filter means water coming up through the filter due to the vapour emitted. Letting the boiled water cool sightly longer fixes that. After trying different combinations of the amount of water used and turning the stove up and down, it seems that the coffee is now on par with what the other machine makes. The result does seem a bit more consistent, though the difference may also be due to the age of the old machine. The "two cup" moniker is a bit optimistic, though maybe I need to experiment with adding even more water. Those are proper Italian cups too, not huge buckets of sewage. So far it seems to be a worthy successor.

    Had four of these Shugart drives a long time ago. Used opto isolated triacs to shut down the spindle motors after a timeout. Also used my own drivers with acceleration and deceleration  tables for the head stepper. Could step them much faster that way and they sounded way cooler (tock-wee-iiiii-eeew-tock instead of tock-tock-tock-tock...).

    That's a neat idea.  I guess you tied into the head load control line?  You could interrupt the AC at the cable without hacking up the control board.

    You're talking software, right?  The controller side determines the step rate.  I would think that you might have to tune that on a drive by drive basis.

    Re Icom 7610, I don't know where it is made, but the build is quite different from the 7300.
    Had my 1st contact on 7MHz sideband - about 2000km away (vk4**) the noise reduction unit is really good.
    I have usually been psk31 on 14MHz, but FT8 has killed that, I miss the fact that with FT8 mode it is very impersonal, but it gets through all the SMPSU hash. One of the local hams is pushing morse so I will take a brave pill, and have a go. Some of the morse transceivers are just so elegantly simple and so effective - it's hard to resist.
    No doubt the device is better than me!

    It has a 3-pin DIN in a 180° DIN5 arrangement and a blower with what look like TRRS contacts on the output tube. The cable is coiled and the housing is all metal. I’ve never seen one like it but could it be from a hot air station?

    The TRRS contacts remind me of JBC style soldering iron tips so I hope no one is trying to do the same thing with hot air by building the heating elements into nozzles! It doesn’t make sense where nothing contacts it to directly sink heat.

    either a vape device, a detector of some type ?  ::)
    A vape of some kind was my first thought too but the cable tying it to something else doesn't make sense for that kind of portable device. It’s definitely got a blower of some kind in there.

    It has a 3-pin DIN in a 180° DIN5 arrangement and a blower with what look like TRRS contacts on the output tube. The cable is coiled and the housing is all metal. I’ve never seen one like it but could it be from a hot air station?

    The TRRS contacts remind me of JBC style soldering iron tips so I hope no one is trying to do the same thing with hot air by building the heating elements into nozzles! It doesn’t make sense where nothing contacts it to directly sink heat.

    So... anyone recognize this?

    A $10 digital tachometer.

    This tachometer works good. And, it's only $10.

    I need to check the governor speed of my lawn mower engine. I decided to test the tachometer and verify it's accuracy.

    First was the shaft speed of a four pole induction motor. 1780 RPM. That's reasonable. I then connected an LED to my waveform synthesizer and set it for 12345 RPM (205.75 Hz). You can see from the picture that it's right on.  My mower engine max speed is 3600 RPM. This tachometer should have no problem with that.

    A Tektronix 422 'mini' oscilloscope. SN 101234
    Bought for the princely sum of six carbon rods. WW2 searchlight carbon rods, so actually rather precious. They went to a good home.

    Now I need:
     * The front panel grounding post knurled nut, missing.
     * Two black knobs for the vertical beam position pots. (someone had replaced them with non-original knobs.)
     * CRT protection plastic sheet. Missing.
     * The internal battery metalwork frame. Missing.  But I can make a replacement.
     * Service manual. Original print, not pdf.
     * Maybe the power cord, which has a very odd AC + DC 6 pin connector to the scope. But I think I will replace that with an IEC
       for mains, and a separate connector for DC power.

    Plus get it going. Reported to be "Used to work, didn't last time he tried it."

    Edit: The Cal-out point is at -2V DC. Looking at the schematics (from tek-wiki) that strongly suggests the -12V rail is dead, but the main switching reg is OK. Good.

    I tore down two Logitech USB webcams, and found out you can make "eyeballs" out of them, as the board is about 10-12mm behind the lens.  Of course, the resolution wasn't too good. However, IVPort Dual V2 (http://www.ivmech.com/magaza/en/development-modules-c-4/ivport-dual-v2-raspberry-pi-camera-module-v2-multiplexer-p-109) and two 8Mpix camera modules, sounds even better.

    A HP 4192A LF impedance analyser, been after one of these for a while.
    Pretty much Gods own automatic impedance bridge for work in the audio to lowish RF region IMHO (5Hz - 13MHz, by which point the VNA is starting to look like a reasonable weapon).

    There are more modern instruments (For proper Agilent money!), but for work a long way from 50 ohms (Where the VNA rules), these are pretty nice, especially if you hook up the GPIB so you can produce pretty plots in software.

    Downside is that these things are not exactly compact, and weigh a ton, but they are proper no messing instruments.

    Now just hope the thing powers up when it gets here....

    Yea, but all the old HP kit was that way, the modern version is a lot more $ then I paid for it, and apart from integrating a LCD and plotting it does essentially nothing new.

    Way I see it, this thing is not any more butch then my network analyser (of similar vintage).

    GPIB and some python should make the thing useful for plotting caps and inductors a long way from 50 ohms (For which the VNA is a better weapon once you reach RF frequencies, but this thing goes down to 5Hz).

    I will probably dig out a few traceable passives and use them to do a check that the thing is reasonably close, if it is, then fine, if not well I have a service manual, and old HP is generally really serviceable, failing everything else it goes back on EBay as a 'parts only' job where I got it from.

    This is not intended for metrology, but as a working tool for winding RF inductors and such (And maybe doing G-B plots of sonar transducers), so if it is within a few percent, that is good enough.

    Short, open and measure something known in the range that I am interested in, not calibration, but reasonable verification, far more important most of the time.

    First job, as always, is dig any RIFA class X or Y caps out of there.....

    Geez, I tried looking at Amazon with no luck, but their search is kind of useless at times. Or maybe they really didn't have black when I looked, it was months ago. Harbor Freight only had house brand, which looks like that flimsy folded metal construction. Too bad cause there's a store 20 miles away. I'm torn now because I found this at Newark a few weeks back. Not as many outlets, but check the price and it's extruded aluminum.

    I’ve got a couple of them in my lab. It’s true they aren’t super heavy duty construction but I wouldn’t call it flimsy. They do have a beefy cord and are ETL certified. I find they’re more than adequate for mounting to a wall or bench and plugging TE into - and at $20 -the price is right.

    Looking at the newark one, it seems I got screwed.  While I picked the Amazon one because of its high density (16 plugs -> 2ft long) as I will only be plugging cords into it, it's really not worth 40 bucks.  >:(

    Yes, you're right. I only said flimsy because I had one similar get severely bent by UPS. If you can walk in a store and buy one that would be no problem, and they're plenty sturdy enough to hang on a wall and plug stuff into.

    Keysight U1620A 2 channel 200 MHz handheld scope. I bought it as having a broken channel 2 but it works perfect. Added a pair of Tektronix THP0301 300 MHz probes.
    With both channels is works nicely to 240 MHz before any aliasing, with a single channel its 3 dB point is 360 MHz - not bad at all.

    Would be nice to have more history on this guy. The earlier handheld Agilent scopes were made in Korea by Escort I do believe. This scope is made in Malaysia and runs WinCE 5.0. It has the typical stainless steel torx screws and the boards internally are Agilent branded. It also uses the same lithium battery packs as the Keysight FieldFox line of handheld RF analyzers. The GUI is very responsive but the software feels like it could be further optimized.
    I don't have the proper power adapter which is 15 VDC @ 4amp. It uses what I am calling a 2.5mm "safety" barrel plug - does anyone know where to source one, I have plenty of power adapters and would be happy to just change the end.

    Attached are a few pics looking at a 1 MHz 1 Vpp signal from an AWG, don't try probing like this at home kids!

    40W 300x200 Chinese Laser Cutter/Engraver with adjustable bed and a few more extras than the really cheap evilbay ones.

    Linky and price? I've been promising myself a laser cutter for a couple of years now and have a bit of spare cash

    This one. Voleren has been around a good while on Alibaba. Most likely you will get in touch with Ronny whose English is really good. Freight you will need to sort out depending on surface or air. I had mine shipped Air to avoid port fees etc.

    Will do. It already has a bunch of the 'upgrades' that purchasers of the cheap blue Chinese one seem to do or have to do when people buy them. To have these done as stock is worth the extra $ IMO.

    Is that equal to the so called K40 laser cutter/engravers?
    I am also interested in purchasing one, but then already shipped from Germany so to evade the import duties and taxes, it would cost around €350.-

    WTF! check the specs on that Brymen BM867s, its not an cheapo meter at all, it's made by the same company who makes the EEVblog meter and the original EEVblog meter was just a rebadged Brymen.

    I think it will sit alongside my other meters, Flukes, 25(s), 27(s) and 8840A, HP 3466A(s), Philips PM 2521, Solartron 7045, Kyoritsu 1400, TMK700, AVO Mk8 and many others both analogue and digital.

    There are varying degrees of voltnuttery, those meters such as you mention simply will not fit in my small lab, I've recently sold on my Fluke 8505A for that reason. To have meters such as the 3458A requires very deep pockets  :palm: which is something most pensioners I know don't have, but if I could afford to, I'd have those meters in a heartbeat, and a bigger house to setup a bigger lab  :-+

    On paper the Laser itself is the same power but the rest of it is quite different. Optics, Nozzle, Slides & Bed are better than the K40. I looked at adding a few improvements for a K40 to bring it closer to this spec and buying this one made a lot more sense.

    Our beloved Australian Government 'in theory' has just added to ALL imports 10%GST regardless of price while it used to be over $1k only along with duty from that point. So we have gone from 'sensible' to STUPID in the last 2 weeks.

    It's one of the few handhelds that can claim 5 1/2 digits on some of its ranges and gives most handhelds a run for their money in other areas too. You don't need exotic and eye-wateringly expensive gear to make it interesting for the voltage inclined folk. Sure a 3458A would be a looker in the lab, but when it comes to poking mains or a board I'm not quite familiar with I'd be more comfortable with this one.

    Nice purchase Specmaster. I've been eyeing its bigger brother regularly, but really don't need yet another handheld. That's no excuse, but knowing it'd go at the expense of other needed equipment is.

    Thank you, I looked at its bigger brother (same physical size) and decided that I'm extremely unlikely to come across any VF drives nor have a need for 2 temperature inputs. I don't recall any other differences in the meter apart from very slightly improved accuracy from 0.05% to 0.03%.

    TBH until bd139 got one, I never really looked at Brymen, then it clicked into place that Dave Jones's first meter was a rebadged one and his latest one is also based on and indeed built by Brymen. There is no way that he would do that if they were not of a reliable  quality, with a high precision standard. While they may not be of same build quality as my venerable Fluke 25's and 27's performance wise they are a match and unless I plan to use them in the middle of war zone will be perfectly adequate for the job.

    I'm other news I'm invited to take part in an online survey by RS on Monday which is all about their calibration dept and service. Bearing in mind the issues I had with my 3478A and how I had to calibrate it myself, should be quite interesting. [emoji106]

    If you are referring to the BM235 and the 121GW respectively, the latter is designed and built by UEi, not Brymen.

    The first line was meant as a joke. Clearly that part wasn't interpreted as intended, so my apologies.  :-[

    As per Brymen, they're decent handhelds that offer a lot of value over more well known brands IME (I own a BM857 which = BM867's older brother). But if I need more resolution than 50k count units can provide (I consider the 500,000 button as liar mode  :o  ;D), I go to my bench meter (GW Instek GDM-8251A (https://www.gwinstek.com/en-US/products/Discontinued_Products/Discontinued_Meters_LCR/GDM-8251A) I got cheap when all the ITT surplus flooded eBay).

    For the record, my experience in volt-nuttery comes from aerospace, so that's probably not helping matters much.

    I can certainly understand the issues of finding the physical space for boat anchors. But the smaller format 5.5 or 6.5 digit bench models would seem to be a reasonable compromise.

    Even on costs, if something suitable shows up on the used market (I know it's tougher in the UK).

    Haha, apology accepted, I did wonder if you was joking as most people would accept that meter as being decent. When you decide not to use liar mode,  how much is it out by when you switch to your 8251A meter? I don't actually do anything that demands that much accuracy, TBH, most domestic radio and audio gear tends to have voltage references expressed in 0.1v steps so even a 3.5 digit meter is perfectly suitable for my needs. That said of course its just like a car, its always nice to have more power on tap in case you need it at some point.

    Aerospace I can imagine might need the extra accuracy and yes, I often look at the items on offer in the USA on Ebay and many times I've gone to click on the BIN button then I remember to check the shipping costs which are often considerably higher then the item in the first place and I back down.  :wtf:

    UEi definitely have a UK presence, I think they're represented in the UK (not exclusively) by Kane and May and badged for British Gas, so I'm pretty sure they'd meet the CAT ratings on the front.

    I have a DM393, nice little meter, bit slow, true RMS, seems accurate enough.

    The BM867 is definitely a decent meter IMHO. It may not have every bell and whistle as it's bigger brother has (BM869 for those that aren't familiar), but the quality and value offered is astounding. I'd actually rank Brymen's value the best I'm aware of for handhelds.

    My major handhelds include a Uni-T UT139C (6k count), Brymen BM857 (50k count), Agilent  U1252B (50k count), and a Fluke 27/FM (https://www.ebay.co.uk/itm/Fluke-27-FM-DMM-Digital-Multimeter/142769818682?epid=1301587929&hash=item213dbe8c3a:g:VpIAAOSw3iBbNlh4) (great whopping 3.2k counts, but built like a tank and is easily fixed as long as you don't blow the IC). There's the bench meter of course, and a few DT-830 freebies (they make great road DMM's and panel meters).

    As per more power, I truly get it, but it's from the lazy POV. Meaning I'd rather use a 50k count meter where a 6k count meter would do in order to take advantage of significant digits so I don't have to do any math.  >:D Toss in the fact I like my toys, this fact doesn't improve my purchasing habits either (within reason, as I'm not that far gone ATM).  :-DD

    In regard to absolute accuracy, do keep in mind none of my meters are calibrated at this point (those that were have expired). That said however, comparing them using an inexpensive voltage reference, they're all well within spec last I checked.  :-+

    In regard to US ebay sellers, I do see decent prices incl. shipping for UK/EU buyers at times, so it's worth setting up notifications IMHO.  ;) The link for the Fluke 27/FM would be one example. Just requires more patience than those of us in the US (and a 230V capable PSU that at most, only requires a different fuse for bench gear).

    Worst case, if there is something specific you're after, posting a WTB thread could direct you to the right item at the right price (i.e. someone might be in the know of the right company close-out & auction house handling it). Certainly doesn't hurt to make such a thread at any rate.   :-+

    I'm a sucker for meters, if there's one thing that could be an impulse buy its multimeters of either digital or analogue and my collection (which I'm thinning down a little to avoid to many duplicates) is as follows;

    Handheld DMM's
    1 x Proster VC97  2k
    2 x Bside ADM08A 6k
    1 x Robin OM840 20k
    11 x Fluke 25 3.2k
    2 x Fluke 27 3.2k
    1 x Brymen BM867s 50k & 500k

    Bench DMM's
    1 x Philips PM2521 20k
    1 x Solartron 7045 20k
    2 x HP 3466A 20k
    1 x HP3478A 200k
    1 x Fluke 8840A 200k

    Analogue meters
    1 x Avo Mk8
    1 x Avo 1001
    1 x TMK 700
    1 x TMK 500
    1 x Kyoritsu 1400
    1 x Robin 2608
    1 x Robin 1502

    1 x Heathkit MM-1U
    1 x Heathkit V-7AU

    There may be in the garage a couple of real cheap and nasty give away DMM's as well.

    I agree those Fluke 25 and 27 meters really are built like a tank and the BM867 has a similar feel to it, although I know that the plastics are not of the same quality but the bumper gives it a great feeling of solidity.

    The Fluke 8840A is lacking the AC option unfortunately which I already have a thread in the WTB thread for this along with a replacement VFD as mine is quite dim as I suspect that it has been sat in a lab somewhere switched on for the duration of the working day at least.

    I think the only extra functions that the BM867 has over the 867 is the function for the variable frequency drives and temperature, neither of which bothers me so I saved myself a huge wedge in getting the 867.

    I don't yet have anything above 5.5 digits but I just know that its only a matter of time on that front  :-DD

    There may be in the garage a couple of real cheap and nasty give away DMM's as well.

    I agree those Fluke 25 and 27 meters really are built like a tank and the BM867 has a similar feel to it, although I know that the plastics are not of the same quality but the bumper gives it a great feeling of solidity.

    The Fluke 8840A is lacking the AC option unfortunately which I already have a thread in the WTB thread for this along with a replacement VFD as mine is quite dim as I suspect that it has been sat in a lab somewhere switched on for the duration of the working day at least.

    I think the only extra functions that the BM867 has over the 867 is the function for the variable frequency drives and temperature, neither of which bothers me so I saved myself a huge wedge in getting the 867.

    I don't yet have anything above 5.5 digits but I just know that its only a matter of time on that front  :-DD
    You are closer to 6.5d than you think; the 3478A is 300k counts (303100 to be precise).

    I have two and I absolutely love them! I suspect these meters go for such low price because of their LCD - otherwise it is an excellent piece of gear.

    I just ordered a mini 50mm cut-off saw so I can cut down 64 pin receptacles to 62 pins seeing as the 62 pin receptacles are now as easy to find as Unicorn poo!  |O

    They are pretty affordable, only $115 aussie pesos delivered from a local seller. I'd guess they are cheaper stateside.

    I'm a sucker for meters, if there's one thing that could be an impulse buy its multimeters of either digital or analogue and my collection (which I'm thinning down a little to avoid to many duplicates) is as follows;

    Handheld DMM's
    1 x Proster VC97  2k
    2 x Bside ADM08A 6k
    1 x Robin OM840 20k
    11 x Fluke 25 3.2k

    There may be in the garage a couple of real cheap and nasty give away DMM's as well.
    Holly crap, you've quite a collection there.  :o  ;D

    FWIW, the only analog meters I have these days are attached to a couple of PSU's I own (PD TP343B & GW Instek GPC-3020).

    FWIW, I've seen threads/info regarding VFD rejuvenation, so that may truly be worth a look IMHO.

    Sorry I don't have more details on this, but I've not needed to do this thus far.

    Exactly.

    Not a huge difference in features as a general rule, but a notable price difference to get the extras that come standard in the BM869 (think there are differences in data logging capabilities as well).

    Certainly seems you're more than bitten by the bug that imparts gear acquisition syndrome though, so you might want to figure out if you need an anti-fungal or antibiotic to deal with it.  :o  :-DD

    Regarding a decent 5.5 digit DMM, I'm sure something suitable will come up for the right price on eBay (US or other locations).

    Yeah, I'm aware of those details that it looks fishy, I guess I'm going to fully test it like forming and leakage test at 30 Volt, this will take sometimes.

    Meanwhile briefly tested capacitance using Fluke 287 are about 75.000 uF (75 mF).  ::)  :-//

    Completely within tolerance. It's rated as -10% to +50%.  Sounds promising.

    I think the main issues with counterfeits would be reliability, which are not really testable with a small handful of parts in a low amount of time. For example, will the electrolytic leak out in a few years....

    I got a Knipex 12 42 195 wire stripper. It seems to work well so far and gives good results. It is rated for 7-32 AWG, but I find that for my cheap 30 awg 'bodge wire', it has a tendency just to cut the conductor instead of strip it. Larger wires strip just fine.

    The only thing I wish was different with mine is the diode test, I wish it had a bit more kick! Mine pushes 3V give or take a tiny bit. my older fluke 177 pushes 7V+ which is awesome and my 289 does around 5v which is decent and bearable! Other than that I find it an awesome beasty and very quick.

    I like it a lot but it only pushes out 2.94v on diode test which is low, my 3466A does 4.66v, Flukes 25 and 27 give 2.48v, my cheap Bside ADM08A is 3.22V, Proster VC97 only has 1.52V, Robin OM840 2.79V and lastly Philips PM2521 3.55V.

    I find the backlight to be a bit flaky on the left side of the screen to a bit strange considering the rest of the performance is (apart form diode test) is right up there with meters many classes above it.

    Yeah, I don't get it either. Most of the time my order gets split up like that. It's kind of crazy, but I figured their logistics must be optimized for very large orders, not small ones like we make. Beats me.

    Just some extra tools:

    - an adjustable torque wrench for SMA connectors. Claimed to be adjusted to 1 Nm, tested with an torque indicator and they did a good job.
    - a crimp tool for terminal connectors.

    And this Keysight scope actually uses a LeCroy ADC!

    Wow, do you have a picture? That is an interesting curiosity, as I thought LeCroy makes their own ADCs (and sample memory ICs, MAMs, as well).

    From this picture I only see e2v ADC, but e2v is rather unrelated. They got acquired by Teledyne last year, but it is the only thing they have in common with LeCroy I'd guess.

    Much less delicate than microphones and scopes, but still electrical-related. Two socket drives, the 'small' one 36mm , and a 48mm extended length impact socket. Both 3/4" inch square drive. The 48 mm one I promptly cut in half with an angle grinder, because I need to 'extend' it quite a lot more. It will have a length of steel tube welded between the two parts.

    These are for disassembling the big old 3-phase motor that came with my recently bought large lathe. I can't start on refurbishing the lathe yet, but I do have space to do the motor. It was made in the early 1950s, and looks like something out of a 1920s Amazing Stories (early SciFi) magazine illustration.

    The shaft nuts that need removing are of course imperial sized, but I refuse to buy imperial wrenches. The metric ones fit well enough.

    Do you mean cut a lip in the faces on a lathe, to center the extension tube accurately? And chamfer the weld seams? I will be doing that. Just haven't found/bought a suitable bit of tube yet, so don't know dimensions.
    Alignment will be by clamping the parts in a bit of L section.

    In the motor, the windings/pole piece seems to be fixed in the frame solely by heat-expanding the frame onto it. I think I need to separate them for a few reasons, so heating the frame up (without wrecking the old windings) will be a bit nail-biting.

    Edit to add: The plate says the motor is Y-wound, and there is no Neutral. Any one know if this is a problem for variable frequency drives?

    Yeah, pretty much exactly that. Some ordinary 2" black steam tube or the bit thinner wall galv water pipe should do the job. Either is just over 2" ID with 2" indicating nominal ID not OD.

    Wanting to sandblast the frame. Also access to punch out the pins securing the brass plaque, from the inside.
    Still weighing the pros and cons. Needing to heat the entire frame circumference evenly, to avoid risk of cracking the cast iron, being one issue. Doing it fast enough to not significantly heat the pole piece and aged winding insulation, another.

    Rust is not the problem, it's the thick multiple coats of paint flaking off, same as on the lathe. With plenty of concave nooks, so forget flapper wheels. Plus wanting to get a painted finish on the motor consistent with the lathe. The lathe paint-removal will be a big job and WILL involve sand blasting. So, the motor too.
    I took the motor frame to a motor rewinding place today, and asked advice about separating the frame and field assembly. Their opinion: forget it. Much harder than you'd expect. Better to sand blast with the windings in place, but protected with something.

    Then driving home I found a roll of old thick carpet on the kerb, so that's my first choice of a protective layer.
    That leaves the problem of getting the nameplate pins out. I think that won't be too hard.

    I think I would forget about sandblasting the motor as being to risky. Leave the brass plate in situ and just some good old fashioned paint stripper. Much safer and possibly less cost as well.

    You're right with the "HF" chopping (they use frequencies in the 4kHz to 16kHz range), but there's no filter inside. They output the raw PWM square wave and use the motor as the filter. Sine wave filters are optional, you'll have to supply them.

    Heh heh, do you think I'd point a sandblaster at a lathe, without first protecting all the precision surfaces?
    Yes, the roll of carpet will be useful.

    Those pins - nameplate fasteners are virtually always hammer-in pins. Very hard steel, with spiral flutes that cut into the base metal. The pin heads are deliberately featureless domes, to make them impossible to grip. The best way to get them out is with a pin punch from the other side, if the holes go all the way through.
    Turns out the holes on this motor frame don't go all the way through, so that left the fallback methods:
    1. Grind small flats on opposite sides of the head, to give something for vicegrips to grab. Then pulling and turning at the same time, they unscrew. But this way the pins lose their original appearance.
    2. If you want to not damage the pins, so they can be reused: Cold chisel with a sharp cutting edge. Put the edge where the pin head rests on the plaque, tap sharply with hammer. Trying not to dink the soft brass plaque, while working round the head of the pin. The idea is to loosen the pin in the hole, and also work it out a tiny bit. That tiny bit gives vicegrips a lip to grab, and then you can twist the pin out.

    Anyway, they're out now. See pic. Very minimal damage to the plaques. One pin head was already partly sheared off, I think from when it was initially hammered in. I got the stub out, fortunately.

    More like a groove, to position the tube. I'll run a bolt through the middle of the set to keep them tight, while it's in the pipe welder thingy (a rough improvisation from a while back.) The steel of the impact socket really doesn't like machining with a silversteel cutting bit. Have to dig out some tungsten bits.

    Nope. With really old things I like to maintain historical accuracy. In another 60 years or so, the next person refurbishing this lathe may wish to put in newfangled brass screws.

    What I'm really torn about, is whether to use boring gray paint (per 1950s original) or something a little more cheerful. I think the latter.

    I was surprised actually. To do anything with the impact socket parts I'd half expected to have to use grinding in the lathe. Something I prefer to avoid, since the grit gets into the ways.
    But actually they are not extremely hard. Silversteel bits do cut it. Just with a high wear rate, and only shallow cuts.
    Maybe I'll still do the grooves with a plain cutting bit. They can be very shallow.

    What I'm really torn about, is whether to use boring gray paint (per 1950s original) or something a little more cheerful. I think the latter.

    Yeah I wondered how you'd get on turning impact sockets.  :scared:

    I was surprised actually. To do anything with the impact socket parts I'd half expected to have to use grinding in the lathe. Something I prefer to avoid, since the grit gets into the ways.
    But actually they are not extremely hard. Silversteel bits do cut it. Just with a high wear rate, and only shallow cuts.
    Maybe I'll still do the grooves with a plain cutting bit. They can be very shallow.


    I guess if it is still in the original paint, you know it  :popcorn:has probably never been rebuilt.
    Motor rewinders used to have a fetish for slathering everything with blue Hammertex paint.

    You have a problem with blue hammertex paint?

    (Pic is the last motor I prettied up, from an old vacuum pump. I happen to have a box full of tins of hammertone blue paint. A freebie. No, I'm not using it on the lathe.)

    good old fashioned paint stripper.

    The key words are 'old fashioned'.  The modern stuff here is useless.  I bought a large can of Nitromors in Homebase (Bunnings before they offloaded it) a few months ago.  It was useless, did not even touch the surface of the 1960s metal paint on aluminium parts.
    I ended up sending the parts off the be professionally striped.   
    According to the striper they changed the formula about 15 years ago, removing the 'good stuff'.  It certainly did not smell as strong as I remember.

    Oh. Good point. Never having used a VFD before, I had assumed they'd all (mostly?) use HF chopping with a filter, for reasonably sine-like outputs. Are there any like that?
    Nope, they all put ~400 V square waves into the motor, with pretty sharp edges.  Most 230/460 V motors handle this pretty well.  If the motor was specifically wound with insulation only good for 230 V or so, that could be a problem.

    You can add series inductors on the motor side of the VFD to round off the sharp edges.

    As an old Oz motor, it will have been desired for 240v Phase to Neutral (415 Phase to Phase).
    The insulation may be quite a lot better than that, as they were probably also sold in WA, which for many years had a 250/440v system.

    I actually used black hammered finish on my bench & shelving frame (steel).  :o :-DD

    It can be had under the Rust-Oleum (https://www.rustoleum.com/find-a-product/results/?x={117DC9B8-66CB-428A-ACEE-641E738E7BBA}&t={4F364F0B-F7CB-4FAD-9D04-070C6CA6EB71}&a=cbg&category=Finishes&value=Hammered) label here (Hammerite isn't available in NA).

    Perhaps it should be relabeled as TerraHertz brand though, as I suspect there'd be added value (suspect he's the type to paint the item as a bonus). Toss in his favorite food & fuzzy logic generating beverage, and it'd make for a nice day in the shop. Paint or not.  ;D

    "Hammerite" appears to be the UK/EU brand name while in NA, it was called "Hammertone"
    The generic name (at least according to Wikipedia) is "hammer paint"
    As @nanofrog observed, Rustoleum is selling this paint in several colors, although not that lovely pastel green color shown by @TerraHertz

    It almost looks like "no-see-um green"

    The good thing I noticed if you clamp it on your ESD mat you don't need the extra cable, it just conducts enough through the mat, at least with my mat I measure a bit more than 1Mohms to earth (mat had 1Mohms to earth).

    Looks awesome!

    (FYI, that’s called a “vise” in English. A “helping hands” are the dinky things with alligator clips, e.g. for holding wires. And clamps are the freestanding things you use to e.g. clamp together two pieces of wood while they glue; that is, a clamp is put onto the workpiece, whereas a vise holds the workpiece.)

    What is the use case for an ESD vise*? I would think it’s not convenient for holding PCBs.

    *Other than the Panavise vises designed specifically as PCB holders.

    Depends if you have 4mm or more room on a side of the pcb, that is enough to hold it steady while soldering, drilling, cleaning, scrubbing, removing solderlacquer etc.
    Also I use it for everything else you normally would use those helpless helping hands for: holding wires, connectors, etc.

    Then it has some extra functionality not found in helping hands:
     - Pressure close flatband headers, you know the connectors on flatband you parallel have to apply pressure to.
     - clamp your plastick or alu box (if smaller than the clamping distance or else you have to clamp on one of the sides) for drilling holes or perform other mechanical operations.

    There is a special pcb holder from Bernstein if you need it, but I don't. When I work under the stereomicroscope I use a flat vise.
    This is my second Bernstein, it is one of the tools I could not work without. If it is in your way you unscrew two turns and it is loose (4 seconds) and can be put anywhere, to mount same procedure.

    Of course. But I needed a reliable 12 V power supply too. Initially I thought the
    12 V supply  from the vehicle was intermittent. Hence the need for a reliable 12 V supply voltage
    The fault cause finally found after some head scratching was an intermittent ground connection on the trailer.
    A plastic retainer in the light assy. was found to be broken (platicizer hardening over time)
    causing an intermittent ground connection. :palm: Fixed by running a long screw through the light assy.

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=485123;image)


    This one was advertised as non working. I only bought it because I wanted the front door to repair an N36L that I already have. Hopefully whatever is wrong with it is a simple fix. If the motherboard is good, I can think of a few things I could do with it.

    Nice, I've also got a pimped out N36L and an N40L I bought for parts.  :-+

    Yeah, once in a while that works in my favor.  The pick-up only on stuff I'm interested in is more typically out in the silicon valley.  The Boston area is still about a three hour trek with traffic, but not undoable.

    And those definitely need to be packed carefully if you plan to ship them - the CRTs are apparently easily decapitated - the guy told me this one (or one of the others he had) had to be replaced due to breakage enroute when he got it.  I suppose that the connector pins for the deflection plates being fed radially through the tube neck cause a stress concentrations in that area, and with the tube held at the front and rear, any bad flexing of the cabinet could mean death to the tube...  *snap*  *hiss*   :-BROKE :palm:

    I still need to bring them inside, but am currently battling with the damned window air conditioner, who's condensate drain got plugged.  Luckily I happened to go upstairs and notice the puddle under the window before it got too big, but there will be some drywall repair involved.  I'm taking a break from putting it back together after cleaning out all the schmutz.   |O

    Paid £280 which is no steal for sure but I felt a fair price.
    It was my Mrs who bought it for me so it never actually cost me a penny, probably cost me double down the road though if past payback on "gifts" from the Mrs are anything to go on! Ya know how that 1 goes?? 

    I had bid £200 on it earlier in the evening myself but there were a couple of other bids on it so the Mrs asked if i really wanted it. I said "yes i wouldn't mind it" so she hit the B.I.N button for me and called it a surprise pressie for me.

    NICE ONE  :D

    It'll probably clean up well with just warm soapy water and a very gentle scrub.
    If you pull the knobs you can clean them in a basin but watch not to get any water inside the front panel with them off.

    Had a quick look at the specs for the 1002 and it mirrors the 210 until you get to the automatic measurements and the screen brightness, the 1002 offers slightly more in both areas but will run slightly hotter because it consumes another 10W. was it really worth the redesign or is the circuitry significantly better and more reliable as a result I wonder? :-//

    Because the old scopes that they were using prior may have been analogues and they just made the decision to swap over to DSO's at the end of their planned life and that just coincided with the release of the 1002 model? :-//

    This is more of a "what did I find in the lab today"?

    Amphonel 132360 (901-10106 seems identical) is a SMA plug rated at 500 connections where the nut does not turn with respect to the pin. This damages the female connector, right? Why would they sell such a thing?

    (What I actually bought today is a rod of stainless steel that I'll try to machine into a replacement gage pin for a N-type Maury gage kit I got from eBay.)(https://uploads.tapatalk-cdn.com/20180803/f774ea4866199f8f2896e3a741413c33.jpg)

    I see some of a similar style used here to plug the non-connected port on a wifi router. You would only screw it on once and then never touch it again. Its probably a few cents cheaper to build.

    The fully kitted out Aeron stool, with the full height, and all the adjustments comes in around $1,400 delivered.

    Some places will sell for a little less than others, but then charge more for shipping, some have free shipping.  It takes about 3 weeks from ordering to delivery.  In my case, it was due to ship 4 weeks after ordering, but actually arrived at about 3 weeks.

    Description:
    Aeron Stool - Bar Height, Tilt Limiter with Seat Angle Adjustment, Fully Adjustable Arms, Standard Armpads, Adjustable PostureFit SL Support, Graphite, Graphite Chassis & Foot Ring / Graphite Base, 2.5-inch Hard Floor or Carpet Roll-Away Resistant Casters with Quiet Roll Technology, Black, 8Z Pellicle Graphite

    That reminds me of when NASA closed their Carnarvon tracking station.
    Serendipitously, Radio Australia was looking for a new site to replace the badly damaged Cox Peninsula
    Station following Cyclone Tracy, & took over the building & surrounding property.

    NASA took most of their stuff away, but Telecom Australia, who operated the Radio stations for RA managed to score several of the very nice chairs, which had pride of place in their control room.

    There were a number of unused offices, which looked like their previous occupants had just walked away one day.
    There were comments about various missions written with chinagraph pencils on some of the glass partitions.
    Really quite eerie!

    Sometimes it's fun to get stuff just for the chance to see what it's like and how it works, especially if you get it at a really good price. Then, put it on eBay. It's like a free eval. ;D

    Amen to that, I do it often but there is a often a very long pause between getting it and going on Ebay which is normally prompted by the imminent arrival of something else evaluate  :-DD

    Needed something for TEA since my last acquisition dates back to may this year, so
    I bought my second HP 6114A precision power supply on the bay.   :)

    My bid was the second and last one. Wish the other bidder never had bid -cost me $10 plus over the starting price.

    Price was $45 but don't ask for the shipping rate from the US over to Europe.    |O

    Nevertheless, it's newer than my first on (still in repair) and seems to work fine.   :-+

    Ah, so you got that one. (I had to say it. Forum members are starting to expect it. :-DD)

    It's a nice one, too. If it's any consolation, the seller wanted $66 just for domestic shipping, which is a bit much. Hopefully, the international shipping wasn't excessive compared to the norm (which, I know, isn't cheap to begin with).

    And, no, I wasn't the one who made you pay $10 over the starting price. ;)

    Or me, but seriously those US prices at times are do darned attractive. Many times I have almost hit the BIN button but been back to reality by those shipping and duty costs, many times doubling or tripling the cost.

    For the express purpose of experimentation, a MiNi70 MOSFET HF PA kit from China, interestingly the eBay listing shows IRF520 devices but the MOSFETs supplied have had the numbers ground off.

    All the SMD parts are already soldered, looks like they've done a decent job of it but I'll have it under the magnifier this evening.

    No, I've no idea who Bobbi2 is either

    That's interesting, same board but it uses a 'proper' RF MOSFET salvaged from cellphone gear, I think an MRF9120.

    I might have my fun with the IRF switching FETs (I'll try a few other types as well) and then see if I can find an MRF9120 to play with.

    And, perhaps, I've got a few MRF175s that might fit as well.

    You hit the point, specmaster.
    If shipping+customs would be in the region of intra-Europe shipping rates my TEA would definitely be worse.   :scared:

    Regarding this second 6114A I searched my ebay history for 6114As being sold in European countries before hitting the button.
    Result was: Even with that shipping rate plus customs it's less than the 6114As sold in Europe.
    How could I resist..?   :)

    Absolutely not an “only in America” thing! Insurance is big business everywhere. But you’ve never seen people who insure as much as the Swiss. Some years ago, it made the headlines when an insurance company here began offering insurance against winning at golf, because the custom for that particular type of win is to buy a round for the whole clubhouse, and with Swiss drink prices, that could be quite expensive!  :-DD

    That would be far cheaper to make sure that you didn't win a round of golf and thats easy enough to do instead of insuring against it.

    BB830 breadboards

    Interesting. Julian Ilett has a video comparing MB-102s with similar (he calls) "fake" versions.
    https://www.youtube.com/watch?v=VerbEZtACwQ (https://www.youtube.com/watch?v=VerbEZtACwQ)

    He compares the clips to show how poorly they open up on the fakes. The fakes are easily distinguished by the uppercase lettering and oddly placed numbering starting from "0."

    I have bought a small pile of MB-102s for about US$2 from ali, selecting only those with the lowercase lettering and they all have nicely shaped clips.

    So, I'm wondering which kind of MB-102s you have been frustrated with?

    Your BB830s have the uppercase lettering but proper numbering so they are something else.

    I wish somebody would make those pre-cut jumper wires with all the lengths in a box the same color. When every length is a different color, color coding becomes hopeless.


    edit:

    I just checked the mailbox and there was a package inside from Alice. $20 worth of cheap toys. I was too lazy to take a picture, so here is a collage made from the "shipped" notification email.

    Gladly because I had some trouble getting them. My first order never arrived (ali was very good with a refund) and I cancelled my second attempt because the seller was taking days just to ship (again, no real problem but by then I've waited pretty long.)

    Thirds a charm arriving in 18 days. So I'm happy with this seller.

    I just got the same kit from Banggood but for $2 more, came pretty quick, too.  I like the strippers, they don't put a crimp in the insulation like the other cheap strippers I was using.  I haven't tried the crimpers yet.  If they work as good as the strippers, it was money well spent.

    I bought a Sony Watchman FD-10A. It's a 2 inch diagonal black and white portable TV that has a CRT. The CRT is unique in that it is flat and bends the electron beam 90 degrees to make it hit the screen (similar to the CRT pictured, but smaller). It is an analog TV and can no longer receive TV broadcasts because all the analog stations have gone off the air. I hooked it's antenna up to the TV output of an old VCR and it still works good (see picture).

    It was manufactured in 1988 and cost about $220 back then. I bought it brand new in the box for $35 from ebay. It's 30 years old, perfect condition, and still works! :-+

    Edit: the beam does not bend 90 degrees.

    Nice ideas and sorry for the confusion! My wife's using the nursing light function every night and is very happy with it. The next step is to get a PCB made in China and to implement a basic user interface for setup. I want it to be usable for people without having to program / flashing anything.

    Those flat CRT's are cool. I have a 4 inch one from an old video intercom (they were used before LCD so the unit could lay flat on the wall).

    Today, I picked up an old analogue Tek scope from Akihabara as I was wandering around. Something to poke at once I finish restoring the two nixie frequency meters/counters I got recently too.

    Annoying yeah, but if that is the price then it's a 100MHz Tek 'scope for about 25 Euros. I'd put up with the inconvenience of having to clean and polish it for that price.

    Its not just the salesdroids.

    Back in the early 1970s a prof in my uni department ordered an HP35 calculator, the first scientific pocket calculator.
    Upon arrival, the receiving/inventory people applied one of those thick aluminum property tags identifying it as property of the school.
    Alas, the most convenient place to put this (unremovable) thick tag was directly across the bubble LED readout along the top.
    Of course, this completely ruined the functionality of the calculator since you couldn't see the readout.
    I don't remember whether they got the bean counters to replace the calculator they ruined.   :palm:   :palm:   :palm:

    Anyways I got one from these guys "Notebookspares" on Ebay who made it a very easy process considering I have never changed one out before.
    1 email and they told me where to get the code from mine so I would order the proper screen 1st time. The screen came in a couple of days and is now working great in said laptop! A very easy process!  8)

    I'll see what to do with the Hewlett Packard 4260A LCR Bridge when it's on my bench.
    It was offered as "For parts" although a test with a resistor was successful according to the sellers description.

    For ~40€ plus 30€ shipping and ~14€ customs and fees the overall cost are not too bad if I could sell the device for a reasonable price...with other feet.   >:D
    And actually I really should sell it because I already have a modern HP 4263A LCR Meter...    :-DD

    My second 6114A comes with feet so now I have two 6114A with original feet.   :-+

    You know how you can drop something and it's more a "light" drop with not much of a thud when it lands,,,, or on the other hand it can be a "HEAVY" drop and a REAL THUD THUMP WHACK!! when it lands?

    Found another toy in Akihabara.

    Will be handy for testing audio amps after a little TLC. Works well after I replaced the fuse. :D
    Looks like it has an ovenised crystal (is that what it's called?) or something, there's a little styrofoam block on something in what looked to be an oscillator section when I took a quick peek inside.

    There is still a lot if you know where to look. :)
    You want to head a street or two back from the main road, heading away from the electric town exit from Akihabara station..

    I recently found two nixie tube based frequency counters. I'll post pics once they are all reassembled from their restorations.


    [edit] Another recent acquisition, yet again from Akihabara. I think I might eventually make a clock, or even grab some tubes and see if I can display video, old school style.

    Last time I was there I browsed Keisokuki-Land which is quite close to the station, across the main street and heading for the river. Good shop to browse, but no drop-dead bargains. I'm also limited to what I can fit in my case on the way home. There are a few smaller "junk component" shops around that area too, but the sprawling "component fruit markets" of the past all seem to have disappeared.

    It has detail maps from 2007, so my street doesn’t exist :D
    But I have used Garmin’s MapSource program with their hiking GPS units, and should be able to get it together.
    The open maps usually don’t have routing info, so the unit wouldn’t speak.
    I was able, at the time, to load open source maps into MapSource so that both could be loaded o the unit, which I’d love to try with a topographic map.

    It’s a serial port, and a data card (prior to SD cards), so I’ll have to rig a makeshift serial cable.

    it was 2nd hand. 
    the factory test/packing sheet that it came with says 1998! so, it's 20 years old.

    It came from a company that had been using it to do their own electronics manufacturing, but offshored recently.
    one of the two parts platters it came with still had components in it from the work they last used it for!

    There are still companies selling new versions of it (or at least still list them in their catalogue)

    Greetings, I’m relatively new here, but Ive been an avid follower/lurker of the Channel and the forum... Guess this thread gets to pop my post-cherry

    I just happened upon this thread, the morning after I made my FIRST scope purchase. Never had a fair/decent/reasonably-fully-functional one before. I currently have use a Sainsmart DDS120 and it’s pretty awful. Recently started a project and found out I need gooder one. Scoped (no pun intended) out the GW Instek 1000-series, the Tek 1000 series, and the highly regarded Rigol 1000-series. And alas, I decided on the Rigol DS1054Z— too bad it won’t ship until Monday. For now let’s settle for the invoice, shall we  8)

    Also decided to finally upgrade the insulated-with-cheap-ass-pvc test leads that Came with my Fluke 179 DMM. Hooray for silicone, hooray for buying genuine!

    There are still companies selling new versions of it (or at least still list them in their catalogue)
    the fritsch one looks ridiculously similar to my 20 year old unit.
    Yes I know but it is ridiculously priced either  :)
    For that money I build my own semi manual P&P, a project I hope to start after my CNC machine is finished.

    I just pulled the trigger on this HP3468A bench/portable meter and recently I purchased this Fluke 8840A which arrived this week and I'm very happy with it, despite being 30 years it is still within calibration and good condition throughout. I'm hoping that the 3468A will be the same and will compliment my 3478A nicely.

    AC and DC TIG, enough amps, and 9 presets available to store your settings for different metals.
    watched some videos on youtube from guys explaining it was a good device. (most of them in german ...)
    I did not want a plasma cutter with it because plasma is with compressed air, and TIG is with argon
    so you have to switch the gas each time you go from cut to TIG. I will buy a separate plasma cutter (and a MIG may be) later.
    and the price was quite nice 700 EUR with a foot pedal, less 100 EUR of ebay gift, total 600 EUR.

    I have that, too, it’s great!! Plus the same from Mueller — it’s even softer (but also several times more expensive due to the much finer stranding).

    I’m curious, when you get around to opening it, whether you find the two colors to be equally soft. I remember that with mine, one color is a tad softer than the other, though I don’t remember which is which at the moment.

    Both seem equal to me. Perhaps an age difference in the stock you received?  :-//

    As per Mueller's wire (413 strands), it's close to what Probemaster is using (440 strands).  :-+ And all of my Probemaster leads I've purchased are notably more flexible than the Pomona 6733. ;D

    Mouser is selling the 18AWG Mueller wire by the foot (1 - 99ft @ $1.38 per) instead of either 10ft or 25ft lengths, so I may have to break down and pick some up. For HV/industrial use though, the inner white layer of the Pomona 6733 would certainly be useful IMHO to let the user know if the wire is no longer meeting spec.

    Nice telescope. What model is it and that mount do you use? And how did you photograph the moon? Once I tried the moon with my Canon EOS 6D, but just a telephoto lens and a tripod, which was sufficient, but for longer exposure time I guess I need a motor powered mount, aligned to the polar star.

    Stacking sounds like a good idea. Does the camera do it? I guess I don't need a motorized mount, if I stack images, if the software can align them.

    The camera may have some stacking functionality but it's much better to use dedicated software. I use AutoStakkert for stacking (https://www.autostakkert.com/ (https://www.autostakkert.com/)) and Registax (https://www.astronomie.be/registax/ (https://www.astronomie.be/registax/)) for wavelet processing. There are plenty of tutorials out there, Google is your friend.

    For that money I build my own semi manual P&P, a project I hope to start after my CNC machine is finished.

    yeah if I hadn't been offered the one I was, I would have gone with something like this to start:
    https://www.tindie.com/products/Abacomtech/ezpick-manual-pick-and-place-machine/ (https://www.tindie.com/products/Abacomtech/ezpick-manual-pick-and-place-machine/)
    It's not much, but it keeps the vacuum tool more or less vertical and steadies your hand for placing. so it's the basics. Plus it generally keeps itself out of the way of the board.

    Then add a few manual reel feeders like this:
    https://www.ebay.com.au/itm/1-set-5-way-SMT-SMD-resistor-capacitor-reel-Feeder-for-DIY-Prototype-Pick-Place/281172131862 (https://www.ebay.com.au/itm/1-set-5-way-SMT-SMD-resistor-capacitor-reel-Feeder-for-DIY-Prototype-Pick-Place/281172131862)

    And some kind of lazy susan I can plop small parts boxes onto.
    https://www.ikea.com/au/en/catalog/products/40176460/ (https://www.ikea.com/au/en/catalog/products/40176460/)

    And that was basically my best alternative to what I got.


    I think there's definitely room in the market right now for a simple and limited but still decent quality manual PnP (with $ and attention spent in the important areas like smoothness and ease of movement, and a simple easy component management system) that a good number of people would buy. even if it was the same price as the cheaper auto ones. Sometimes you just want a reasonable number of parts with relatively easy access, and a nice stable tool to manipulate them into place.

    Imagine this, but with an auto rotating parts carousel instead of just 10 feeders. I think that would be well worth the $ they ask, if it's well built and reliable.

    On the pure DIY side, there's some projects online you could combine to make something very cool. though a lot of the DIY designs that do proper X-Y rails seem to have physical design that surrounds the PCB more than I'd like...  still they are out there and documented so shouldn't be too hard to duplicate.
    Also there's this, which looks great - an SMT parts sucker with pressurised blow-off for dropping the parts precisely.

    There's a video on youtube where someone adapted his CNC to be a PNP, with button and slider control of the axis movements and buttons for pickup and drop.
    I think the problem with that, as well as many of the existing DIY machines (and the cheaper commercial ones) is that the PnP head can't move that far, and there's often also limitations to external access around the edges of the movement due to construction.... As a result, they can't access enough different parts.

    If you have to make piles of parts on or around the PCB so you can then pick and place them onto footprints, I think the machine is very limited and is going to still have a lot of the fiddlyness of a full manual setup.

    A carousel is annoying in some ways because you need to load compartments up with parts, and you lose orientation like you get from a reel or tube... but once they are in there, it gives you the ability to reach a lot of parts while only taking up a relatively small amount of space inside the range of the PnP head.

    The modern Fritsch unit has an option you can buy called the Paternoster, which looks amazing.. would be very cool to DIY.. it's basically a desk-sized automated parts library. you have a bunch of boxes in it that are full of parts, and each row as 12(?) parts boxes in it, and it has lots of rows, so can store many hundreds of different parts... you can set things to bring up each row as you need it.

    Agree, I find the DIY solutions with the strips stuck somewhere a big mess and nice for one off but unhandable for small series (keep on sticking).

    It takes up so much unused space in the middle, it looks great but not that space sufficient and there are limited amount of parts to be placed. You probably want one carousel per project but then what do these cost a piece  :scared:

    Wow, wow, wow. Any idea what the price is ?
    503 parts, let me think, resistors in the E12 range in three package sizes is only 216 boxes, that leaves 300 boxes for capacitors, jellybean parts and small ic's.
    That is enough for me and most hobbieists  :)  Or put a second one besides it  :-DD
    The challenge for DIY is the lid mechanism.
    You can really tell the difference between the good ones and the bad ones (from Ebay are some really bad).
    The lids tend to snap off after a dozen times or get kind of stuck.
    If you make the mechanism smooth you don't even need the lids on each box.

    In my thirties I used to go the Tandy shop in Tottenham High Road and drawl over those TRS models they had on display in the window. In those days as a young parent etc, I just could not afford a computer of any kind. A few years later I did get my first by using all of my money I got given to me for birthday and christmas presents and then I could only afford a pocket computer, little more than a calculator, a Sharp PC1211 which ironically was also badged as a Tandy TRS80, pictures attached. I still have the PC1211 somewhere and it works and looks much better than both of those in the photos  :-DD

    In my thirties I used to go the Tandy shop in Tottenham High Road and drawl over those TRS models they had on display in the window. In those days as a young parent etc, I just could not afford a computer of any kind. A few years later I did get my first by using all of my money I got given to me for birthday and christmas presents and then I could only afford a pocket computer, little more than a calculator, a Sharp PC1211 which ironically was also badged as a Tandy TRS80, pictures attached. I still have the PC1211 somewhere and it works and looks much better than both of those in the photos  :-DD
    Nice that you have one; I remember drooling over their pocket computers PC-1211 and PC-1500 back in the 1980s. Living in Brazil, we never had anything like the TRS80 Model 100 there - only the Brazilian clones of the TRS-80 Models I and III (DGT-100 and Prológica CP500).

    Ordered a Pressmaster crimper for insulated terminals from ebay, link here (https://www.ebay.com.au/itm/PRESSMASTER-KSA-0760-CRIMPER-INSULATED-0-5-6MMSQ/253823559420?epid=7014209068&hash=item3b191026fc:g:RXsAAOSwSKtacaIG). (no affiliation with seller)

    It's in Australia, $43 which is a bargain as that tool usually goes for $170 or so brand new from RS.

    Anyone know if it'll work okay with the TE Connectivity/AMP PIDG insulated terminals? (specifically the common Faston-type for IEC socket wiring and such, I could always just get the normal non-PIDG type terminals)

    I thiiiink it'll be fine since it's only the adhesive lined heatshrink terminals that need a special tool as to not damage the heatshrink, can anyone confirm?

    You basically stole it for that price.  :o  ;D

    As per working with the TE Connectivity/AMP PIDG terminals, it'll do them quite well.  :-+ Or any other decent vinyl or nylon insulated terminal for that matter (Pressmaster is a truly top quality tool, and ODM for a multitude of terminal manufacturers). It'll even do the heatshrink terminals quite well also, but will deform the heatshrink portion of the terminals (would do for hobbyist use, but wouldn't pass inspection when it matters).

    Same here. The frame alone would be well worth having at that price, and other dies are available to make a really nice dedicated crimper.

    FWIW, I've one of their MCT frames (http://www.pressmaster.se/product/mct_frame) that take interchangeable dies (I've multiple dies for it). For insulated terminals, I use a Panduit CT-1550 (https://www.panduit.com/en/products/wire-termination/crimpers-cutters-strippers-accessories/crimping-tools-pumps-accessories/ct1550.html) (rebranded Wezag CK100 (https://www.wezag.de/index.php/en/products/tool-series/crimp-hand-tools/ck-100) with a custom die set for Panduit).

    I got it for much lower than web price since I have a friend who works for Lenovo, and he got me an employee voucher.

    I would like to have a friend at Lenovo like you. Why not a P51? With the P52 out the price is even better now.

    Nanofrog, if you use your workstation to build code (like I do and probably blueskull as well), the multiple cores help a great deal by the -j option of make/gmake. Also, several technical applications use multiple cores (Altium is one of them) and, even if an application does not use this capability, it still helps by having them offloaded to other cores.

    Been keeping an eye out for a used Cleverscope for quite a while, and picked up a base-model CS320A last week. I ordered the isolated sig gen for it, which should be here next week. It will be used mostly for FRA stuff. I'm especially interested to compare it to the transformer-coupled measurements I've been making.

    I bought a HP 4338B millohmmeter from a seller in Great Britain.

    Watched it for quiet a while being offered on evilbay without being sold and being re-listed over several months.
    A few days ago I negotiated the starting price of the auction with the seller and after all I was the only bidder for the price we agreed on.  :-+

    Had to hurry a bit before GB exits the EU to get it without having to pay customs fees..   >:D

    BTW: I'd like to see the Brits not leaving the EU, but that's only my point of view. Don't want to discuss politics here.

    They're from an ebay shop, areyourshop-003. Electrically the cables and adaptes look OK on the 1502C TDR. Mechanically, the BNC plugs leave some room for enhancement. When plugging or unplugging them, they often don't move easily. SMA connectors are good enough for me, not as nice as the real good ones.

    I picked a few things up from Banggood.  Another Wiha screwdriver set to put in my toolbag in my company van.  I really like this set and I bought the second set on sale for $17, which was quite nice.  The wire strippers work much better than the cheap crap I had, I haven't yet tried the crimpers--again, better quality than what I had and they are ratcheting.  I haven't yet tried the deburring tool but have wanted one and finally, a cheap stripped screw removal set.  If it works half way decently, I might spring for a better, locally sourced set.

    Got the Pressmaster crimper today, thanks @nanofrog I wouldn't have known to search for Pressmaster if you hadn't mentioned it in an old post when giving advice on crimp tools.

    I still have trouble crimping AWG 22 wire to a red terminal (AWG22-18), but the specs mention 0.75mm^2 minimum even though it also says AWG22-10, go figure.  :P (it's only for DIY hobby stuff so I just fold over the wire if I have to)

    It works BEAUTIFULLY with AWG 18 wire on red terminals though, I'm very happy with it especially because I practically stole the damn thing. For any Aussies out there you can find still it on eBay if you search 'pressmaster' but the price went up to approx 50 dollarydoos shipped.

    The bottom corner has a non slip pad so you can press it against the desk and it won't budge, very useful if you have girly hands like me and you can kind of focus on positioning the wire and terminal instead of worrying about squeezing it hard enough.

    Now I'll be on the lookout for used crimpers from this day on in case I find an old AMP one for cheap to slowly build the collection.  ^-^

    Just remember those contacts in there are not rated for continuous operation at 10A, and also they are not fail safe when disconnecting into a high current. They tend to weld together under heavy load, so best used in conjunction with a sensitive 16A AC1 rated contactor. Those at least will, when paired with the appropriate overload, provide good protection. Hope you also got some LED power on indicators to go with them.

    Yep, get that screen replaced. I assume you got the HDR model?

    Correct.

    Very nice, there seems to be some question on if it really is HDR on the Lenovo forums. It seems to depend on your definition of "HDR".
    I was sad they stopped shipping OLED models so I'm sticking with my Yoga X1 gen II - I can't give up the screen.

    I think I should share my experience with you. Since I returned a Samsung monitor with thousands of dead points 10 years ago, I have never encountered the same trouble.  :-DD

    Did you mean a deal line or some tab/cog/tcon issues? If a panel itself has that many bad pixels, I wonder how on earth it did pass QC?

    Thousands of dead points. I was told that it was because of the sealing problem at the time of manufacture.  :palm:

    Just remember those contacts in there are not rated for continuous operation at 10A, and also they are not fail safe when disconnecting into a high current. Hope you also got some LED power on indicators to go with them.

    It's for a 450W 220VAC Max load, it should be safe. I did not know that thow... sometime I am lucky. Thanks I appreciate the advise!
    Yes I have LED for it!

    I actually thought the teflon was inside the floppy cover, not on the disk itself, to reduce spinning friction.

    It was always much less painful on Amiga's and even less so again on Mac's - Amiga's used the Shugart "Disk Change" signal to recognize a new disk and Mac's had a motorised Floppy Drive insert/eject mechanism.

    A Sharp CE-140P colour dot printer with an included Sharp PC-1350 computer.
    To bad about the leakage ob the screen (The dark brown colour is just the camera angle), but I already have the newer PC-1360 computer, so it's not so bad.

    Also on the way is the serial communications cable, so I'll be able to write software on the convenience of my PC then transfer it over to the Sharp.


    Now to find paper rolls and ink.........

    Almost like a plotter that works in raster like an inkjet. Really weird and interesting. I might have to do a teardown video.


    Also, the serial cable turned up today too! Fun for the whole weekend! :D

    Just looked at some Youtube videos and the service manual, that's pretty wild! It's basically a 4-pin (1 per color) dot-matrix printer, but instead of the needles hitting a ribbon, they sit in a tube of ink, which they transfer directly. (Actually the same exact principle by which tattoo guns transfer ink to the needles!)

    You can easily record the programs these days to the Audio input of the PC.
    No need for a cassette tape anymore.

    Interestingly, all my stored programs of old cassette tapes from the 80s
    could not load anymore. But I had them all digitally on an old floppy as well.

    The PC1350 and PC1360 were amazing machines in the day and still are today.
    I even liked the PC1350 more than the PC1600, because of its slim factor.

    These days I have several PC1350 laying around and being used all the time.
    Once in a while you can find them cheap on ebay and may find one broken with
    a good display and replace yours.

    What about McMaster-Carr?  (Obviously not for this one, but maybe something to consider in the future if you haven't already?)  They're quick, and I've always found their shipping charges reasonable if not downright cheap.

    I think I just found a DigiKey for mechanical parts! Thanks!!!

    You're most welcome.  I almost didn't mention them as I figured most everyone already knew, and I have heard some complain that they're too expensive. I use them all the time both for work and personal stuff.  And yes, that's a very apt analogy - they are pretty much the Digi Key or Mouser for everything else besides electronic parts.

    Metal stock is more limited than McMaster-Carr, but Grainger and Zoro can be good places for those types of products as well (tooling, fasteners, ...).

    Grainger owns Zoro, which offer discounts from time to time (can be quite decent). Shipping is reasonable too IME. It's easier to find what you're looking for on Grainger's site, then port the P/N to Zoro. They even sell on eBay, so you can use PayPal should you choose.

    My X1C6 repair has arrived today, and my bet was right -- it didn't fix the dead pixels.
    The legally blinded technicians failed to even spot the dead pixels, and they released the panel and shipped the machine with the same panel back.

    New depot service order placed and escalated. Let's see.
    I'm now thinking to return the entire unit and order a similar unit with FHD monitor instead.

    When can PC manufacturers get the quality to MacBook level :palm:.

    Good luck!

    The worst is when they have 'zones' of allowable dead pixels on the screen.. ANY dead pixel drives me insane. I've been lucky that my panels are all clear, but then again, I ain't going to push my luck by examining toooo closely. :D

    Ordered two 8" by 8" by 1/2" plates, one 8" by 8" by 3/4" plate, and one 8" by 8" by 0.09" plate. Both 7075-T651.

    Why 7075? I always buy leftovers from toolingplates, prices vary from €3-€5 per kg.
    example 5080 1" thick 42x21cm (aprox 16x8") 7kg+ Price: €25.-  :)
    i don't know where you live but it is worth while looking for some scrap dealer, hardware left over hoarder and such.
    I only buy new when I need one very large piece, does not happen often.

    Just got myself a new toy. (Pic from the listing). A Sony Vaio VPCP11AKJ

    Should be easier to use this in the data center rather than lugging a full laptop around.
    The bigger screen should be easier to squint at than my phone too.


    I gotta stop buying so much stuff. :D

    Why 7075?

    Half of the order was for a custom tool, and that's because the original bed of my CNC was made of 7075, so I figure I can use the same material.
    The other half was for cases of one of my inventions.

    Both are prototyped with cheap 6061, so I have little risk of ruining $320.
    Personal funds or is this you're research?

    I ask, as even $320 can be very dear to a starving student that's covering it from their own funds. But whilst it might not be peanuts to a research grant, it'd be more tolerable at least.

    If you're unwilling or unable to answer, I'll understand. It's just that your situation as I understand it brings back some memories for me (funding issues + politics were bad enough I quit after completing my MSc).

    FWIW, good on you for putting any funding issues and/or any other obstacles aside/beating them down in order to acquire your Ph.D..  :-+ I just didn't have any more fight left in me.  :-[

    I once had a Vaio Z Flip 2015 bought at Akihabara 99 back in 2015. It had a very bright and vibrant screen, but the workmanship was horrible.
    Bad installation resulted in high edge/corner stress that caused the screen to bleed light and fade, it also caused the touch screen to mistrigger due to the presumably pinched touch screen flex cable.

    Because of communication problems (at that time I was around JLPT N3 level, I could speak Japanese in a a casual environment, but not with technical terms, and the store employee that handled Vaio product line couldn't speak English AT ALL), I didn't manage to return the machine.

    I ended up disabling touch screen from Device Manager and used it as a conventional laptop for 2 years before the fading and back light bleeding got so bad that it looked like Sadako was going to climb out of the screen at any moment.

    That was the last Vaio I've ever bought. 200k Yen down the drain. I should have known Sony ditched the brand for a reason.

    Yeah, they dropped the ball a bit. Story of Sony almost all round in the 2000's....
    I would never buy one new, but the second hand market has hopefully weeded out the duds, so I'm crossing fingers for a good one.

    @Terraoperative @Gamalot

    My X1C6 repair has arrived today, and my bet was right -- it didn't fix the dead pixels.
    The legally blinded technicians failed to even spot the dead pixels, and they released the panel and shipped the machine with the same panel back.

    New depot service order placed and escalated. Let's see.
    I'm now thinking to return the entire unit and order a similar unit with FHD monitor instead.

    When can PC manufacturers get the quality to MacBook level :palm:.

    Good luck!

    The worst is when they have 'zones' of allowable dead pixels on the screen.. ANY dead pixel drives me insane. I've been lucky that my panels are all clear, but then again, I ain't going to push my luck by examining toooo closely. :D
    As a lifelong Mac user, it’s been years since dead pixels have even been on my brain’s radar. Last time I ever dealt with them was in my PowerBook G3 from 2000. It had some screen issue (I think it was dead pixels, but honestly it’s been so long I can’t be sure any more), so I called them up, they sent a mailer, and less than a week later I got it back with a new LCD in it, which works to this day.

    Anyhow, I vaguely remember that even when Apple did have allowable dead pixel policies, they tended to be very generous about fixing them even if the policy requirements weren’t met, since at the time (before the iPod and then iPhone really bolstered the company’s income), their core users were graphic designers, photographers, and videographers, and Apple respected them deeply, including their (understandable!) sensitivity to dead pixels and other screen defects.

    But I haven’t seen a dead pixel on a Mac since then, nor frankly on any other LCD gadget I’ve used (whether my own or someone else’s, regardless of brand), so I kinda assumed that the LCD makers had simply managed to improve their processes to the point that dead pixels just aren’t an issue any more. The rapid move to 4K also supported this suspicion, since for most people, a 4K TV adds no value at all, and 1/4 the resolution (1080p) means a far, far lower chance of dead pixels, and thus fewer dud panels, and thus higher yield, and thus lower cost.

    So, out of genuine curiosity (not snark), is dead pixels something that people still run into in PC laptops?!?

    I use an Eizo brand monitor, no dead pixels. I've never seen dead pixels on an Eizo panel so far actually.
    On my Dell Precision laptop, I have a 15" 4K panel, no dead pixels I can see there either (maybe they are just too small for my eyes... :D )

    P.S. Speaking of that PowerBook, a few weeks ago I dug it out and reinstalled SimCity 2000 to show that game to my 11 year old nephew. (Yes, he liked it and we had fun!)

    But man, playing around with that system, you realize how much things have changed under the hood without us noticing! It’s crazy how incompatible those systems have become with the modern Internet. On Mac OS 9, it’s now nearly impossible to use the web, even to download from vintage software archives, because they all use HTTPS, and modern HTTPS uses encryption standards that didn’t exist then, so they literally cannot connect. Even the last Mac OS X (10.4) that runs on that system can’t download anything, the Safari (and IE 5) in it can’t connect, for the same reason. There’s a special version of Firefox for PPC Macs that can connect. That works great for the vintage software archives, but trying to browse the modern web shows you just how batshit crazy insanely CPU intensive modern websites are. (And that special Firefox doesn’t work with modern ad/tracker blocker extensions, so the 400MHz CPU has to take the full brunt of the dozens of pieces of JavaScript bullshit on most sites.)

    So then, OK, I’ll download on my modern Mac and copy things over... well, can’t do it via LAN, again, no mutual protocols (in a default OS config on each end). OK, well, I’ve got a USB floppy drive! Nope, Mac OS X shed the ability to write to Mac-formatted floppies over 10 years ago. What does work is external hard disks (the PowerBook has USB 1.1 and FireWire 400, the modern MacBook has USB 3 and Thunderbolt, and my Mac Pro has USB 3 and FireWire 400/800) and Zip.

    Which brings me to my “what’s your latest purchase”: I scored a USB Zip 250 drive. (Has the PCMCIA adapter card, too, but that’s PC-only and unneeded on my USB-capable PowerBook anyway.) Since I have an internal Zip 100 module for the PowerBook, and my original SCSI Zip 100 drive, too, Zip 100 is the only format I have that all of my computers can read and write! Most of my computers have optical drives, but not my oldest vintage Mac (external CD—ROM drive got disposed of ages ago :( ), and the optical drives in the remaining vintage computers are starting to fail, having trouble with marginal discs of any kind, be they burned or stamped.

    On the bright side, maybe I’ve just been good about storage, but I have yet to encounter a single failed floppy or Zip disk, and my old CD-R data archives also seem to be flawlessly preserved. (It’s all been migrated to HDD with separate backups, but still!)

    I’ve also been assembling a “new” hifi system from what’s basically Sony’s last real lines of pure audio gear, all QS series from around 2000ish. So far, I’ve snagged a tape deck (TC-KB920, the last deck they ever made. Sadly I damaged some of the electronics while trying to repair a failed potentiometer, so I still need to do repairs on it. I picked up a cheap donor deck with a dead transport and damaged housing but intact electronics as a source for unobtanium ICs so I should be good), an MDS-JB930 MiniDisc deck (Sony’s penultimate MiniDisc deck), and a CDP-XB930 CD player (Sony’s last pure CD player in the 900 series — all the later ones were SACD, and don’t support Control AII bus for system automation). The last two I got lucky on and got for a song, about $90 each, far less than they’re selling for, and they’re in absolutely mint condition! :D I also bought (and still need to pick up) a CDP-XB740 CD player, which is truly Sony’s last pure CD player, but which should support CD-RW playback, too. I got it for a whopping $40! No idea why nobody bid it up more, got lucky I guess!

    So I still need to get the tape deck fixed, as well as pick up a matching receiver or amp. Modern amps have at best one tape input/output, so it has to be a matching late-90’s model that has two, one for tape and one for MiniDisc. And of course another set of speakers. Most likely, the XB740 will end up connected to the home cinema, while the rest will become a stereo for the bedroom, where I currently must use the Mac Pro for music playback. (Speakers are good, but the Mac Pro pumps out a lot of heat, so using it just as a music player is silly.)

    I also got a portable HiMD recorder and a tape Walkman a bit better than my old one (I replaced the belts in both). I still love MiniDisc; those damned magneto-optical discs are just indestructible!

    Heh, yeah! I mean, think about a 4K phone display at 700ppi or something; even at half-arm’s length, a single pixel is not visible to the naked eye. Dead pixels are probably absolutely invisible to the naked eye (whereas hot pixels probably still stand out on a black background).

    For sure. I think on desktop displays, dead pixels are truly a thing of the past. Same on TVs. At least it is on a name-brand product, which uses only top-grade panels. I suppose that lower-tier brands that use lower-grade panels might have a higher risk, but I still don’t recall seeing a dead pixel on them in ages, either!!!

    My two years old work laptop Dell Precision 5500 has a 4k screen and no dead pixels, as well as a much more recent Viewsonic 27'' 4k display. Perhaps this may be a brand issue.

    My wife got a Samsung Galaxy S8 that had a couple of dead pixels and they replaced the phone without any questions.

    I was a MiniDisc guy back in its day. I still have a MZ-N1 portable recorder in great condition, but I sold my deck many years ago. The N1 managed 50+ hours of battery life. Try that on an iPod.

    The STR-DA4ES (or DA7ES) receiver may be suitable for your system. Two tape (in/out) loops plus two more video loops, so plenty of analog line-outputs for recording purposes. It has Control-A1II and Control-S jacks, and supports two-way remotes. It also has two multi-channel audio inputs (5.1 and 7.1) and 7.1 pre-amp outputs. It's becoming harder to find those these days. One downside is the use of SAP15N (and -P) transistors for amplifier output devices. These have a built in emitter resistor as well as temperature-compensated biasing circuitry, and they are no longer made. That makes repairs more difficult if ever necessary.

    the late 90's early - 2000's a lot of Sony's items had proprietary leads, cables, memory and psu's, the less said about the pc attempts the better

    Got an issue though; the thing is massive!  I can get away with a lot, using the dining table for this and that, but my better half will show she has a limit if i tried the unthinkable.  Couldn't not buy it though, so i need to store it, until i can work something out, or we get a bigger place.  Any reason if wrapped nicely, that this shouldn't be ok in a normally insulated and boarded loft?  The UK winters are a bit of a concern, but is there much to worry about - the thing is a tank!

    This weekend I came across an electronic heaven storage place. The guy cleared old electronics departments when the buildings were abandoned in the 80s and 90s.
    He told me he just had to drive a big truck and they put everything in it, nothing was to be left.
    He didn't have to pay anything, the alternative for the company was to pay a lot of money to a recycling firm to clean out the building. Good old times.
    He sold most of it in the years that went by on fleamarkets and the sorts and actually he has no clue what is left in all the stored boxes. The majority is radio HF oriented which I do not find interesting.
    The small parts like connectors, switches, relays etc. he has decently ordered for the fleamarket and asks a decent price for them.

    I came there and asked for some specific items but never found them  :)
    I spent four hours feeling like Indiana Jones in the big warehouse looking in all the boxes and coming home with much more than I had anticipated, caught at home by SWMBO which was less pleasant  ;)
    Here is a picture of some of the stuff I bought, 4 different Weidmuller clamps in 100pcs/box.
    Funny thing is I just ordered the thin plastick end isolators, and for the 20 pieces I paid more than 2 boxes of clamps.
    Better used one of the clamps and removed its conductors  ;D

    In a spur of the moment decision I purchased all these faulty meters, I guess if I can make 2/3 good ones out of them I will break even and hopefully learn something along the way. I also have 2 X metrix mx67 testers which I purchased separately that I hope to make at least 1 good one from (I'm waiting on a transistor). It's a steep enough learning curve I've repaired dim displays and broken input sockets before but never down to component level (on multimeters). I've spent a bit of time researching online and I've an idea where to start but I won't be able to get my hands on them until at least the end of the month.

    I have a couple of good meters, programmable power supply, Metcal soldering station and IPA ready to go so I'm not short of the correct gear, maybe just a bit of knowhow [emoji1](https://uploads.tapatalk-cdn.com/20180911/f11766f51744356498f0544781b11657.jpg)(https://uploads.tapatalk-cdn.com/20180911/53b4baca780773033a61a454fc9c5319.jpg)

    Anybody suggest a simple IP camera viewer SW for W10 and Chrome ?
    These any good ?

    Wow that screen looks nice and colorful for something with a floppy drive in it

    Hmmm, it's modern tho, so what's the slot thing ?


    I ordered 30values x 10pcs of 1/2W Zener diodes. I like to have stuff on hand, which reminds me I need NTC thermistors.

    Bought some parts that I fetched from customs today -after paying customs fee:
    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=521735;image)

    2x multimeter fuse 440mA
    2x multimeter fuse 11A
    10x precision resistor 100 Ohm 0.1% 10ppm
    25x Vishay PTF56 resistor 5.315k Ohm 0.1% 5ppm 0.125W
    5000x 100 Ohm 1% SMD-1206 resistors (1x full reel)
    16000x 10k Ohm 1% SMD-1206 resistors (4x full reel of 4000)

    Bought from *bay seller n2cbu -am fully satisfied and like his motto: "From my basement to yours: If you don t need it, I HAVE IT!!!"   :)

    Some other items that arrived lately:
    Some y-adapter power supply cords one plug to three IEC connectors.
    I have to solve the problem having occupied 18 of 18 power outlets left for the lower three shelves of my workbench with even more Test Equipment needing power.    :palm:

    Some cables and jacks for network and telephone. The Telekom will terminate my telephone/internet access contract because they're dismissing their ISDN-network (no spare parts available, obsolescence..) so I need to switch to VDSL (50MBit download rate with VoIP). The old crappy inhouse cabling of my flat is ok for ISDN (telephone) and 6MBit ADSL but not for modern VDSL. Consequence: I've got to get new inhouse cabling and new internet access router.   :-\

    Kontaktchemie KONTAKT LR, PLASTIK 70, ISOPROPANOL KONTAKT IPA and IPA 70% and 99,9% (plus distilled water)- different cleaning fluids for cleaning my somewhat crusty 4338B.

    I was a MiniDisc guy back in its day. I still have a MZ-N1 portable recorder in great condition, but I sold my deck many years ago. The N1 managed 50+ hours of battery life. Try that on an iPod.
    I KNOW!!! Sony's efforts at long battery life (didn't they brand it "Stamina" or something) were amazingly successful. I remember one cassette Walkman they made in the 90s that could run 37h off a single AA alkaline. When the original iPod came out in 2001 with its 10h of playback on a charge, I remember thinking "Man, if only Apple could leverage Sony's power management expertise!". Or, like, let Apple design the enclosure and the software, and let Sony design the hardware innards.

    And there is precedent for that: Apple's first battery-powered Mac was the awesomely quirky Mac Portable, which was a luggable whose weight was the same as a Mac SE desktop (just with a sealed lead-acid battery responsible for the weight instead of the CRT). Apple's first round of actual laptops was the 100 series (https://en.wikipedia.org/wiki/PowerBook_100_series). It comprised the PowerBook 140 and 170, which Apple designed entirely in-house, but also the smaller PowerBook 100, which was actually built by Sony, who was given the Mac Portable schematics and asked to make it little! (Though it was released at the same time, the PowerBook 100 was actually designed later than the bigger models, so its aesthetic is somewhat closer to later PowerBook models, like the Duo series.)


    Of course, in the intervening 15+ years, Apple has improved its power management dramatically. But it's clear that the iPhone series was what really gave them the push they needed to invest in this.

    The STR-DA4ES (or DA7ES) receiver may be suitable for your system. Two tape (in/out) loops plus two more video loops, so plenty of analog line-outputs for recording purposes. It has Control-A1II and Control-S jacks, and supports two-way remotes. It also has two multi-channel audio inputs (5.1 and 7.1) and 7.1 pre-amp outputs. It's becoming harder to find those these days. One downside is the use of SAP15N (and -P) transistors for amplifier output devices. These have a built in emitter resistor as well as temperature-compensated biasing circuitry, and they are no longer made. That makes repairs more difficult if ever necessary.
    Cool, thanks for the info, I'll keep an eye out!!!

    Ha, thanks!
    I repainted the silver panel surround as it was a but ratty, and the iso-alcohol started stripping the paint..
    That and the capacitor replacement kind of snowballed a bit. :D

    The actual case has a few scuffs, but I'm not prepared to strip that back and repaint it just yet. ;D

    Can you show a bit more about the use? I thought a micromanipulator was something to interact with samples under a microscope... clearly that is not the only application?

    Using a micromanipulator under a microscope is one way to use it, but you can also do more stuff that involves manipulating (lifting, re-arranging stuff, pick and place stuff, spot cleaning) there are a lot more ways to use it instead of picking up components, actually you can:
    1. rotate the components while placing and any properly sized object while placing it.
    2. pick up tiny screws and object rather than components. Cellphones screws are ok, cellphone cameras are ok.
    3. you can also use hot air + this to rearrange items if something goes wrong and the margin of error is certanly better than using a tweezer.
    4. pick and place, assemble things (provided they are not too hevy, but a cellphone tiny motor is picked up easly if the vacuum is good and the cup is correct.
    5. you can pick up adhesive tape with special cups. The tiniest cup is less than 1mm ( I'm planning to buy it)
    6. it is handy. and for handy I mean, really handy compared to a tweezer: you don't screw around with tiny objects and thus the chance to lose them on the floor  is decreased because It has continous vacuum, and you won't lose your object once it is picked up. Definitely not true with pick-up pens.
    7. you can also suck up stuff such as pools of flux, but I don't reccomand it. Sucking up solder is discuraged due to clogging issues.

    If you are good enought you can also pick your nose with it!  :)

    The pictures of it are taken in such a way that the damage cant be seen

    Hopefully its repairable (heat and a bit of persuasion), if not I will part it out

    Mind you...  we BOTH regularly get frivolous things on Ebay etc, when ever we want  ;D

    I get my cheap Electronics kits/fun-stuff, and she gets her 'arty-farty' stuff !!!
    It never ceases to amaze me how I can buy some Electronic wizardry that used to cost
    say $50 in parts, for say $4.95, and free shipping from China !! ???... It's crazy...

    MY money is hers, and visa versa, so buying 'presents' looses meaning...
    So although something 'personal' was given for her recent birthday, that is minor.
    It's how you wake up that day, and express your love. You make her feel special...
    It's somewhere new & exciting that you take her, before sunset champagnes.

    I bought this a few weeks back, but I got the replacement transistor I needed to fix it today.
    It's a 'Digipet-60' nixie tube display frequency meter. Designed primarily for ham radio use.

    By talking nicely to Advantest support (They used to be called Takeda Riken way back when), I found a Japanese guy who is a self proclaimed 'denshi otaku' (electronics geek) in the company who went above and beyond to find their very last copy of the manual, including the schematic, and scanned it for me. :)

    It got the usual replacement caps, clean of all the things, and deoxit on the switches etc. Works quite well now.

    Yeah, was doing some HV testing of PCB coupons under vacuum last week, and doing so in a pressure range that led me to distrust the the el-cheapo bourden tube gauge I had (things seemed to be arcing too much - suspect actual pressure was much lower than indicated pressure), but one much too high for the TC gauge I have, so I ordered the Baratron.  Happened to see the HP dual supply for about $50 plus shipping, so I snagged that, too.  Convenient as the Baratron wants +/-15 V.   :-+ (Any justification is good justification, right?  ;D )
    (Truth be told I have another coming, too - made offers on both, and both were accepted.   :palm:  :-DD )

    And as for the 6515A, I don't care to piss it off.  I figure I've appeased it - dropped something like $35 to buy a pair of good MHV connectors to make leads for it - it had best be satisfied, if it knows what's good for it!  >:(

    And of course the threaded KF-16 adapter ordered from Amazon to get the Baratron plumbed into the kluge was shipped via DHL, and took a side trip from L.A. up to Washington State on its way to the northeast, so it *might* be here tomorrow.  DHL is teh suxors in my experience.  :rant:

    I got some big chips today:
    * AM1808
    * TMS320C6748
    * XC6SLX16-2FTG256C

    All of which in BGA packages. I have a free sample of UniIC DDR3 too

    (P.s. I wonder how profitable is it now to start a cryptocurrency mine on my spare FPGA dev board, based on EP4CE6F17C8N)

    I picked up another cool thing from Akihabara today... I just can't resist buying more stuff, even when I am 'behind schedule' on my restorations by multiple bits of gear....
    Just gotta find a user and/or service manual for it now.... Then I'll know how to calibrate and test the thing to find what's wrong with it. :D

    (The store also had a big ol' DC programmable load for about 50 bucks too, but it's a bit big for anything but a dedicated trip to grab it... I kinda want it pretty bad though.)

    He is moving his business, and it popped up in the move, unused for a while. Big move, in physical terms he moved 20m, but this has taken him nearly 3 months so far, as he still has to keep on running his manufacturing side with no disruption in the orders being delivered to his big customers. Nice machinery there, a lot of it PLC and specialist, and he is definitely passionate about having it working to the best it can do.

    My present frequency counter is an HP 5384A that only goes to 225MHz.

    Picked up this Systron Donner 6054B from the hamfest. It handles 20Hz to 18GHz with 1Hz resolution, oven stabilised oscillator and GPIB interface.
    Also included was a second unit without the covers as a "spare".
    A few repairs later both units now meet specifications from the user and service manuals from ArtekManuals and checked against a GPS disciplined Trimble.

    Quote from: lygte-info.dk on the Power Cube
    I am not that impressed with the power cube concept, I do not like wires in all directions.
    I am even less impressed with the usb output, it has a lot of noise, fixed Apple coding and only power enough for one (high current) device at a time.
    The usb output is safe and works acceptable, but gets fairly hot when fully loaded.

    I like the tests and the teardown.

    I brought some Anker usb chargers some years ago as I know what went inside and what to expect from the review and no problems with them so far.

    https://lygte-info.dk/review/Review%20Charger%20SkyRC%20MC3000%20UK.html

    I wanted a Lithium round cell charger for years but I didn't know which one to trust and didn't want an alien faced charger that tells me nothing about the battery's voltage and condition. Most lack discharge and cycle.

    Yes that is what her technician told her that it was an M.2 but not that it is a variant.

    I even ordered the wrong boards for all the different types available such as m key and b key and had to cancel them later that night after I looked at a picture of the A1370 motherboard.

    I did keep an M.2 NGFF b key and mSata and it has a controller "Asmedia ASW1542 <writing rubbed off>" on it whereas the Airbook 20101/2011 SSD adaptor just has a regulator and some capacitors on it that plugs straight into the sata port. I ordered the other Apple 2012 variants just incase someone else brings me another one and they stop selling them. I have seen little m and b key interposer boards to fit standard SSDs in the Macbook Air or Retina from Amazon but I read that the they don't always work.

    Yup I can also say they are well made. Tough as hell wee things!
    I ended up getting another half dozen of the other different ones too when I ordered them. It's amazing how often I use them! I can remember thinking "more junk from late night Ebay trawling" when they were delivered! How wrong was I?

    These are I believe NOS tektronix probes and arrived all factory fresh and sealed with the tektronix labels everywhere but aged looking. But warning has been noted and I was never intending to probe voltages anywhere near that rating but maybe the odd poking around and power supply rails etc upto 600V and as such will probably never get used in earnest but I felt at that price I'd better grab them just incase I ever needed to work on power supplies at that kind of potential.

    Nice, you can DIY the battery packs from a few D cells (I think), some tape and copper foil. I have made two packs this way.
    They still die quickly because the scope does not have any charging circuitry.

    The THS scopes run fine without the battery pack. So keep the packs outside to save them from being overcharged if you don't need them. NiMH doesn't like the continous charging the THS does. NiCd is more tolerant to this.

    I would advise that you keep the batteries out of the units, my 720's LCD polariser failed within a week of last use, the NiCd battery died at the same time - I can only guess that it was the battery out-gassing that attacked the screen.
    Or a terrible coincident.

    Going to have to attempt a polariser replacement once I get my hands on some polariser film.

    Sadly, there doesn't seem to be a service manual available for these generators and they are a bit fiddly to take apart and work on. One piece of advice I would give you is don't run it with the covers off for very long unless you blow it with a cooling fan. The thermal management of these generators is dodgy at best and I think part of the reason mine had parts removed and damaged from the main RF board was because the repairer let it overheat with the covers removed. So it developed more problems the longer it was left running. It went away with one fault and came back with unrelated parts missing and parts damaged and it had a string of problems because of this. My guess is that the repairer just gave up on it but they left a real mess inside and didn't even put it back together properly. I think it is designed to suck in cool air at the grill at the front and draw it over the RF section and then the warm air is blown out of the back. So without the covers it will overheat. This assumes the fan on mine is the right way round!

    Nice to hear! The reviews are quite good for it too. I won't push it anywhere near it's limits so it should fly all day long with my use. It's "marmite" looks are quite nice I think.

    It's always good when someone can give you real world info because they have actually used the thing in question themselves. I did dither and sway a bit and nearly bought the Predator 300 and also the 15" Omen too. Once I settled on the Omen machine I then knew I would be spewing if i'd got the 15" and not the 17" as there was only £100 difference between them.

    I'll report back once I've had a chance to properly use it  :)

    So again a find from visiting my favorite metal scrapyard.
    This time I encountered a metal dumpster full of Assembleon feeders.
    Upon asking how much they would cost a piece, the man said €2,50 per kg :-DD

    Unfortunately many of them were already looted, motors were ripped off  >:(
    I ended up with 15 pieces for €100.- , many more good ones around but hey I could not carry more of them with me.
    Now I have to find schematics for them or reverse engineer them.
    If anyone has some schematics please pb me : Assembleon Type:  PA 2655

    Sorry for the lousy picture from the scrapyard,  I still have a Nokia stupidphone from 2005 or so  :)

    I’ve been looking for a new backpack for a while. My 12-13 year old crumpler laptop bag is getting on a bit and recently I’ve been needing tools on the go more and more. I looked at lots of varieties of tool backpacks / technician bags to get one I wanted but they seem to be seriously heavy duty for people using them 10 hours a day on building sites, through to not useful for anything.

    I finally bought a fluke pack30 and while it’s a pretty big bag, it feels like it could be a bit better laid out.

    The side “wings” would be more useful if they were wider (deeper) to put things in, but they are only quite thin. The main section is meant to open all the way looking at the press photos, but it fees like you have to force it to open that far which makes me cautious of the durability in the long term.

    Being in Australia the 12 month warranty from fluke doesn’t mean jack with consumer laws (a $300 backpack will be seen that it should last longer than 12 months and will be covered by consumer protection).

    Vacuum 2 stage pump with mist eliminator, Alcatel 2012. Not exactly portable

    Since Alcatel didn't exist for years now, that has to be second hand.  I have one like that (bit bigger, Alcatel 2033) so I'll mention a caution, just in case you didn't know.
    First time you try running it, do it outside.  Because those oil mist filters use a cartridge that can become oil saturated, then air can't go through it. To prevent the pump from blowing itself up with overpressure, the mist filter has a spring on the cartridge, so it pops up and lets air go around it if it's blocked. Result: when I turned mine on to test the motor rotation (3 phase) the pump filled up the room with oil fog in about 2 seconds flat before I could turn it off. Oil last used in a university chem lab environment. I ran for the door holding my breath.

    I couldn't find a source for replacement filters, so did a bad thing - soaked it in solvent, dried it, resoaked, etc. After this treatment it works, but of course will forever back-stream solvent into the pump. For my use, that doesn't matter. Hopefully.

    Post by: PartialDischarge on October 14, 2018, 10:31:44 am
    Thanks TerraHertz, mine comes from a chem lab too and it seems pretty unused aside from the dust from being stored probably years aside. The filter seems mostly dry, anyway I will probably build in the lathe a coarse carbon filter to put on top of it. The oil is clean but a bit dark, so I bought a mineral one (sunoco iso68) to replace it. Will use it to pot electronic circuits.

I know there's a lot more stuff inside it compared to my last laptop but "gee whizz"!
    Happy with it so far but i'll let you know if I find anything that bugs me other that it's fat azz!  :)

    Yeah, they're a beast of a machine in weight. We were seeing around 3.2 GB/S from the SSD, be interesting to see how yours compares as I think it's slightly newer...

    Today AliExpress sent me a small pile of wrong parts. (After about 300 orders I'm pretty happy.)

    Arrived in the post yesterday, this fine Data Precision 3500 multimeter! It has a 5½ digit Panaplex display. Seems to work OK. There's an edge connector on the back to connect to a the DMM's internal signals, allowing for external control and readout. Date codes show that is was built in 1974 or so.

    Interesting; I haven't opened my 102 yet, but this looks quite similar to the RAM modules of my original TRS 80 Model 100.

    My 102 seems to be fully equipped with RAM (it says 29xxx Bytes free), but the original Model 100 has only three out of four memory slots.

    I have the 17” nvidia 1070, 7700hq CPU, 1tb ssd, 16gb ram, 4K gsync display with the big battery. Really nice for working anywhere even though it’s about two years old now. If you didn’t get both HD filled but it was an option you can buy the cable and bracket and install another yourself. It is pretty handy having a few TB HD space sometimes. Also if it goes on sale soon you can usually get them to give you the difference too. Nice laptops though and they seem to hold up well over time.

    These were indeed more for the Model200 which could hold 72kRAM, I believe it used bankswitching.
    I gave mine away 8 years ago, sometimes I still regret that, it was a very nice piece of hardware.

    The Model 100 and the Tandy 102 go up to 32kB and the 8080 has 16 address lines - certainly some memory bank switching would be needed to get the full 72kB.

    Good luck. My 102 has been working flawlessly, but my Model 100 (I got a few years ago) has a very intermittent issue where, from time to time, it refuses to turn on for many retries, only to magically turn on again with absolutely no apparent reason. Any memory contents are completely wiped when this happens.

    I have tried many things to make it reliable again, to no avail. I need to bring it back to my desk and try different approaches.

    New toy day!

    Got a Yokogawa/HP 4276A LCZ meter for just under 10000yen delivered (about a hundred bucks).
    Cleaned up nice for the photo (also I replaced the strips of wood it had foam taped to the bottom for feet with proper HP ones), and if I can track down the required obsolete semiconductors and transistors, I reckon I might be able to build the Option 001 DC Bias Board Assembly. The full schematics, BOM and board layout are in the service manual which is awesome.
    It also needs a new 2.4V NiCd battery and maybe a card edge connector due to the usual leakage and corrosion, and a replacement fan, but it apparently works according to the seller.......

    Too bad the front terminal addon options are so stupidly expensive... I might have to put the 3D printer to work to rig up a terminal slot thingo for quick testing.


    I also got a fistful of capacitors from Digikey today to replace the old ones in my 8903B Audio Analyzer too.
    Surprisingly almost all the caps are tantalum throughout, with only the main bulk smoothing caps and a couple others (which I think are bulk smoothing/decoupling too probably) being aluminium electrolytic.

    Marantz (Superscope) CD-330 Professional Cassette Recorder.

    Blue is weird. In many ways it’s actually a terrible color for displays, especially pure (monochromatic) blue, like most blue LEDs, since that’s the lowest-contrast primary color, as our eyes are the least sensitive to it. That’s why blue LED displays are so annoying. But VFD blue is not monochromatic, it’s usually closer to teal, so it contains a lot of green and a bit of red, too. So it can be excellent.

    Human eyes are most sensitive to green and it is the last colour you lose in an accident such as a chemical into the eyes. I was told that is why emergency showers / eye wash stations on industrial sites have green lights above them.

    Green is the color we're most sensitive to, I've read. If you want to read a ton of research on the relative merits of different color LED displays I highly recommend going to PubMed and plugging in terms like "blue LED" and you'll find a bunch of stuff. What I found to be the most interesting is that some colors are apparently good for your health, while others are demonstrably not. What you said, tooki, has the ring of truth to it to me. (bright) blue LEDs literally hurt my eyes, while VFD light, and also green ones, totally different. Its relaxing. Also, the green ones seem to last longer. I have a night light that has a bunch of green LEDs in it thats been running pretty much continuously for years and it doesn't appear to have gotten any dimmer at all. Which is pretty amazing.

    The blue colour of emergency vehicle lighting is somehow related to the little fuss our countries had nearly 80 years ago...

    In Germany, the blue light was introduced in 1933. In order to meet the requirements of air-raid protection (blackout), the police vehicles were then specified to be equipped with blue light, since blue light has the highest scatter in the atmosphere and was therefore not visible to bombers at high altitudes.
    In the same year, the fire brigades were equipped with the blue light, too.
    The introduction of the flashing light or the rotating beacon instead of a calm glowing light was only in the 1950s.

    Much more important today: The blue colour is not used in any other traffic sign or lighting.
    Therefor very easy and fast recognizable.

    Just FYI, I think you mean “traffic signals”, aka “traffic lights” (Ampeln), and those never use blue. Signs are the printed things (Strassenschilder), and those most certainly are routinely made in blue.

    Sure. I apologize. My "dumb" fault.  :palm:  |O |O |O
    I stand to be corrected. It is all about traffic lights and lighting in traffic, of course.
    Every traffic sign regarding the destination of highways (Autobahnen) is blue with white lettering on it, for example. Some other "normal" traffic signs, too.

    But I asume: That´s enough OT...

    The lights here in Japan are green (well, to me anyway :) ), but they call it blue.

    I'll point out a random green light or green thing to my (Japanese) wife and friends and they'll say it's midori (green), I point to the same colour green traffic light and they'll say aoi (blue). However, the Japanese word for blue also encompasses a lot of what we would call green too.
    The use of midori as green as a separate colour instead as a shade of blue only really became common post WWII. Ancient Japanese had no distinction between blue and green at all.

    I think the lights were bluer in times past, but they are definitely green now with the LED's being used these days, I guess the name just stuck.

    I haven't seen the blue traffic lights in many years to be honest. There used to be a lot more of them. Since they swapped to LEDs I think they are all green (at least where I tend to be between Tokyo and Nagoya), but the older ones were definitely blue as can be seen in the picture I attached. I think there are also parts of China where blue is still used.

    They are also still "sideways", as far as Europeans would be concerned.

    It’s true, I’ve never been to Japan. (Sadly! I wish to change this.) But traffic light colors are determined by international accord, and it’s red/yellow/green. That it’s often a bluish green (as it was in many US traffic lights, too, until LED came along) doesn’t change that it’s still green.

    I think I have a reason to why Japanese traffic lights are blueish.

    Here's my hypothesis: Maybe when incandescent lights were used,  blue lenses were used so that with the yellow incandescence it would make 'green'. Then when they retrofitted LED bulbs, be it green or white, the different colors would appear. Giving the blue-greenish tint or the blue tint. Not to be confused to the newer and modern installs where the whole light is just an array of green, yellow, or red LEDs. 

    I have seen city maintenance taking one apart and the incandescent bulbs painted in the specific color even thought the lens had a color to it. It was off so I couldn't see if it was green or blue.

    Way back when, I had a short term contract building the green arrows for traffic lights, They used round tapered prisms around 75mm tall, with a cap pressed on the back to accept a fibre optic harness - The fibre optics are mounted in resin with a halogen bulb clipped into a housing the later ones had simple cob led setup to replace the bulb, iirc the led boards where £350 each at the time

    I don’t think LED retrofits were ever put behind the lenses of old fixtures. (Nor does it make any sense to use white LEDs, wasting tons of energy as heat, when native green exists. And since native green LEDs are essentially monochromatic, their color won’t be changed by a filter.

    But I do believe you’re right as to them choosing turquoise filters to try and appear more neutral green with incandescent bulbs.

    Yep, thats because I got them primarily to replace defective switches on the front panels of audio gear such as TEAC DAB/FM/AM/CD receivers and other similar things in their range that all use these switches. I recently had to replace all 11 of these on a front of one receiver because it would not switch on and that is because every single of those switches was open circuit. Fitted new switches and it sprung to life again and has been saved from becoming landfill. :popcorn:

    I bought two electronic screwdrivers today. :)
    Both are made in Japan by Shirakawa Densei Co., Ltd. (since 2000: Shirakawa Nitto Kohki Co., Ltd.)

    #1 is a Delvo DLV7331-CKF  0.3 - 1.2 Nm with DLC1212-GF power supply
    #2 is a Delvo DLV7540-MKE 1.2 - 2.7 Nm with DLC4510-JE power supply

    I also ordered a Fein 90801012008 zero gravity mini balancer (0,5 - 1,5 kg). This one should play nicely with the ca. 650g of the DLV7540. Before getting a second one, I want to try it with the DLV7331 (350g), but I guess another option is needed.

    They are still very useful instruments. I bought a 8842A with the -09 true RMS AC option, and the -05 IEEE-488 option, which both work fine, and calibrated some years before. I especially like the very high input impedance for voltage measurement (> 10 Gigohm). How much did you pay for it? I got mine for EUR 281.50.

    A bit off topic, but does anyone remember when there was a big fuss about luminescent sign material?
    The idea was that it was printable, just like normal stuff, but if it had a DC voltage aplied to it, would glow.
    Manifold uses were forecast for this "wonder material" ----the problem was that all the jobs suggested were
    very effectively done by reflective signs, which require no power supply.

    By the way, do any other countries other than the UK use illuminated "keep left" & "one way" signs?

    Japan uses some illuminated signage. Mainly LED based or backlit plastic like a shop sign.

    The stuff you are referring to is EL panel, like EL wire. It is mostly used for back lighting small displays and other niche applications.

    The backlit ones are the ones I remember in the UK.
    Of course, my visit there was many decades ago, so they may have changed over to LED ones.

    Yep, that's the one!
    There was an article in "Electronics Australia", back in the day, proposing multiple uses for it in street signs & so on.
    I though at the time it was all nonsense, considering all the reflective signs already in use.

    There was also a project by Studio Roosegaard and Hejmans in 2012, where they developed some night glowing paint that charges over the daytime and glows for about 8 hours.

    Sure. I apologize. My "dumb" fault.  :palm:  |O |O |O
    I stand to be corrected. It is all about traffic lights and lighting in traffic, of course.
    Every traffic sign regarding the destination of highways (Autobahnen) is blue with white lettering on it, for example. Some other "normal" traffic signs, too.

    But I asume: That´s enough OT...
    Spain has LED versions of regular signs, like when entering tunnels. Those are blue and white. I linked it below, as it's a large image.

    Beautifull, how much are those new and what did you pay for them if I may ask ?

    SRP is something like: DLV7331-CKE 440€, PSU DLC-1213A-GGB 210€, DLV7540-MKE 525€, PSU DLC-4511-GGB 250€ (prices + VAT, from weidinger.eu) but I paid 135€ inkl. VAT plus shipping! :box:

    There are currently two units of (I guess) DLV7331, one is missing the torque selection wheel including PSUs on eBay Kleinanzeigen for 150€ asking price. If you are interested, I could negotiate for you.
    These pop up on eBay and small ads quite frequently for decent prices though. I had to research quite a bit to get an overview on all the models (which is of course part of the fun in hunting down lab stuff).
    Both units I bought take standard  1/4’’ hex bits, while others may need special halve-round driver bits (there seems to be a standard among Delvo and HIOS devices for that).

    A Fluke 8840A bench multimeter including the AC-09 option off ebay. Supposedly working, otherwise condition unknown … Looking forward to the shipment!

    They are still very useful instruments. I bought a 8842A with the -09 true RMS AC option, and the -05 IEEE-488 option, which both work fine, and calibrated some years before. I especially like the very high input impedance for voltage measurement (> 10 Gigohm). How much did you pay for it? I got mine for EUR 281.50.

    I got it for €157 shipped, after some negotiation. A real bargain if it works (he had no ways of testing it but was able to show me pictures of at least the display showing some figures …), then again I might have to shell out for spares and/or calibration. Cross my fingers …

    And yay, the high impedance, 4-wire-measuring and general good quality of this thingy sucked me in.  8)

    Just received a very nice email from Fluke Germany, they still service and calibrate it, only the ISO 17025 accredited calibration/adjustment amounts up to a whopping €442,68 (incl. 19% VAT and shipping). So I might go for trying to calibrate it myself as a first step.

    I forgot to mention above I also bought a Voltcraft MS-1500 lux meter, because my eyes aren’t what they were and I plan for changing the lighting on my bench. I know some architects that use it and they say it’s pretty exact. Measures up to 40,000 lx (or 4,000 fc).

    I’ve got the same one and like it a lot. :)
    For me it comes in handy when designing lamp prototypes and from what I read it is not too bad in terms of reliable data (as you pointed out). I just need ball-park figures though.

    A "Card Phone", not to be confused with "Phone Card" which I collected in my youth... 

    Quite a neat little phone, has a battery disconnect switch too, thought it might be handy to leave in the glovebox with a pre-paid long-expiry sim in it.

    (https://i.imgur.com/BmgrReU.jpg)

    Thought about leaving it my wallet, but sitting on a lithium-ion battery probably not a good idea, although the case does seem fairly robust.  It's about 5mm thick 85mm tall and 50mm wide.

    Spare blades for this razor cutter. The interesting part is the cutter, itself. Great for all sorts of electronic uses... I particularly like them for separating plastic "tree" parts... Header pin strips, etc. Clean separations, perfect, every time. Mine are the smaller of the two sizes of the Craftsman brand. Old Model 37300.

    About $150 shipped from ebay, a bit cheaper if you are in the US probably.

    https://www.ebay.com/itm/273516247147 (https://www.ebay.com/itm/273516247147)

    Still a bit expensive, but they cost what they cost.. No way I'd pay the $400-odd some sellers ask for...
    It's cheaper than a new Rigol anyway, plus the Tek scope is rated to 300V Cat I/Cat II and 150v Cat III, the Rigol is 300V CAT I, 100V CAT II.

    Some 50W LEDs in this nice format I hadn't seen before at this power.
      https://www.ebay.com/itm/50W-High-Power-COB-LED-Lamp-beads-White-Red-Green-Blue-with-60-degree-Lens/232590344184 (https://www.ebay.com/itm/50W-High-Power-COB-LED-Lamp-beads-White-Red-Green-Blue-with-60-degree-Lens/232590344184)

    Unfortunately there doesn't seem to be a reflector and external lens set suitable for these yet. Hopefully soon.

    The lens dome on these appears spherical, is 22mm dia, and made of fairly rigid silicone.
    All the lenses are clear, with the color-shifting phosphors in a thin layer over the LEDs. So of course the LED chip array is quite visible when running. At low power anyway, I don't expect looking at it directly at 50W would be possible without filters.
    I haven't run them at full power yet.

    Much like the 50W square LEDs, I bet the red ones can't actually take 50W and will burn the phosphor if you try.

    Yes, if you're into SMD and/of lots of testing of discretes, get some proper Smart Tweezers.
    I've had a pair of ST3 for years and they get more use than my DMM.

    these aneng probes are really bad quality when you hold them. you don't know what you're measuring. but they are cheap. your choice...
    the tweezers that are with the deree de5000 are of really much better quality.

    Hmm, it also exhibits another unwanted behavior if strict observance of the instructions aren't followed. It will if applied to liberally become like solder mask and nothing will stick. From that it's a very fine line to the point where the user/operator looses total control for a number hours. [emoji1787]

    Four Huber Suhner Minibend-12 precision SMA cables. Rated to 24 GHz but I tested them to 26.5 and they look good. So nice to have flexible test cables that also perform quite well and don't stress the connectors at all. I believe Shahriar uses a variation of these in several Signal Path videos.

    Nothing like "cable or connector porn"!
    I want an sma depth guide/guage, I have the 'medium' strength sma torque wrench.
    One of my bits of crazy gear is a noise source - it actually comes with a 3.5mm connector (a posh sma really) - first thing was to put a really good adapter on it - so I didn't muck it up!

    I feel so ghetto.  My favorite tasty beverage is a shot of Grey Goose out of the freezer.  A very rare shot between the diabetes and minor cirrhosis of  the liver(not due to alcohol).  That means you can't have my liver.  Even with fava beans. :popcorn:  I also enjoy an occasional beer, not the 'murican piss water called beer, more of some of the local microbrews.  Oh, and the even more occasional Sake with sushi.  I am definitely a light weight.  I stopped the self abuse in my 20's before I could tip over into alcoholism.

    Freshly delivered from eBay: a power supply, a diode, and a 6.5 digit KVD. Unfortunately, I can't find any information on the model, "PPM  412", with 1V and 10 V ranges, built in 1981. The board has points labeled 100V and 1000V, so I figure there were other higher voltage models. The left shield contains the zener reference (it appears to be ovenized), while the right has the upper ranges of the KVD (with dozens of trim-pots). The output Cliff-brand binding posts were broken in transit (will be replaced with parts on hand, but eventually some Pomona 3770). Once I get it working, I'll post more photos.

    It does indeed fit well. Perhaps I shall do that with my K2700.

    Also of note is that bumper will fit on the HP 3468B and 3478A DMMs. I think it may fit the E361xA power supplies you have there.

    I just needed a few funny sizes capacitors for a repair project so went over and got them from the new Altronics store at Airport West which I had mentioned a while back in another thread. They are going to organise and post me out a trade card which works out to be a substantial discount off their regular prices, they even gave me the capacitors at the lower price which was pretty good really considering I haven't dealt with them for quite a while. They also had a very nice looking illuminated magnifier on special which I didn't get and now regret, I might have to go back later on this week for one. I have no affiliation with Altronics whatsoever and am just a regular trade customer.

    The "bulbs" are Nixie tubes. They need around 170VDC to illuminate. Not for absolute beginners, but also not what most would consider very high voltage.

    Agree with McBryce, they can be quite dangerous so you need to learn how to work with high voltage DC.

    One of Dave's videos is about Nixie tubes and well worth a watch.

    You can also get VFD 'tubes' which are a bit friendlier to work with.

    Yeah!
    You might say $&@#%€£¥¥#####&&&@@@!!!, if you touch it, but it is normally not capable of enough current to do you any real damage.
    I don't know why people are so scared of a bit of DC HT---back in the day, we wouldn't have learnt anything if we had that attitude.

    Just don't put your fingers in the wrong places---- after all, you wouldn't put your fingers in front of a jigsaw, or touch a soldering iron tip "just to see what happens!"

    It seems to me that people tend to be far too risk-averse these days.  I'm not advocating for wanton idiocy, but with a bit of knowledge and care, working on things with 170+ V rails carries little risk.  I started playing with old tube-type black and white TV sets at about eleven years old; they typically had B+ rails that were in the 300V neighborhood, along with 15-19kV CRT second anode supplies.  My knowledge about such things at that point came entirely from reading; no one in my family was into electronics.  (My father had a ham license and had done some shortwave stuff before I was born, but had no station or gear by the time I came along.)

    I also remember old project books in the library in middle school that likely dated from the late 50s - early 60s (this was in the late 70s) that were all transformer powered vacuum tube projects.  Too many people today seem to think that anything over 12V is high voltage...

    I bought one of those Kogan DC pedestal (https://www.kogan.com/au/buy/kogan-premium-dc-motor-pedestal-fan/) fans. I like how it has a very low minimum speed setting compared to the $10 cheapies I have from Bunnings.

    At the lowest speed it only draws a couple of watts for a gentle breeze which is perfect for sleeping. The $10 fan draws 30W/36W/40W for low/med/high, so it might pay for itself if it lasts >10 years ahahah.

    I already have a GPS-disciplined DS3231 TCXO on a Raspberry Pi set up to be my Stratum 1 NTP server inside my home network, and I have set up all my local computers (including the authentication server) to use that as the clock source. Usually I use GPS PPS as the synchronization pulse, but when GPS is flaky it switches to the DS3231.

    Also for non-believers of the unique piece of technology this is, here is it measuring a 50Mhz sine amplitude, put out 500mVrms, measured 520mVrms

    I have a pile of 2FA kit for use with various contracts I work on, it's quite common.
    Can those be wiped and reused? YubiKey can be wiped of its contents and repurposed.

    I suspect not by the end user, there must be a way to get your 'secret' onto them and they must be registered somehow as they can be revoked but the back end is not something I have access to.

    I have torn one down after it had been revoked but other than a set of programming contacts there's nothing that looks as convenient as the Yubi

    Depending on what technology they used, it might be reprogrammable. At least (if you can find the documentations and if it is Flash reprogrammable) it can be wiped of all data and programming and you can build your own crypto code into it.

    Unfortunately no, the standard in bench dmms is high impedance below 10 or 30V, like 10G, and then 10Meg and up to 1000V only, for the 3478A, 34401A, 3458A, etc...  I'd prefer to have a higher flat input R and up to a bit more voltage like 1500 or 2000V.
    4.5 or 5.5 digits mean nothing when just probing causes a 30% change in the signal. I understand that oscilloscopes need to keep input Z low, but never got why the standard for DMMs is only 10M, when compensation is not needed.

    Actually quite clever, do not design the electronics with expensive high accuracy components, just adjust the readout meter.
    Could be something we can re-use in this century as well if we make "intelligent" meters.
    It just has to display the correct value for the incorrect internal output.

    A case of the right place at the right time... Bunnings Warehouse (Hardware retailer here in Aus) had a clearance rack of light bulbs, huge haul of LED bulbs for family everything $2 a piece  e.g. Pack of 3 x  10.5W LED bulbs for $2
    Looks like it was to make room for new releases of the same product  :-//.

    The stock supply was all devastated within a few hours, apparently some electrician came in and offered to buy whatever was left...

    BTW it is really hard (impossible?) to find LED bulbs rated for enclosed light fittings.

    LED's don't give out much heat in the first place, so it is likely they don't need a specific rating for enclosed fittings.

    Err.. LED lighting gives out plenty of heat, that is the main killer of LEDs, insufficient cooling, be it passive or active.  It's unlikely to cause a fire, but putting most leds in an enclosed space will almost certainly dramatically hasten it's failure.

    LEDs are more efficient than other forms of lighting, and I can run faster than a one legged man in an ice storm... neither is anything to brag about.

    Well done, I replaced mine and brought extras when they were about $3-4 which was about 50% off or so. But a 3 pack for $2 that is a score. The new ones I saw were warm/white switchable but waste of money and more things to go wrong.

    I've noticed no failures so far since I've had these. If you want you stretch your $2 you can always choose to repair as well :D.

    Congrats, blueskull. The PM300 is a nifty meter - its only issue for me is the absence of some sort of tilting bail. I am always having to find something to keep in at an angle.

    I went for a walk at around midday today and ended up at the local weekend trash and treasure market so I went in for a bit of a look around. I stumbled across one seller who had a few used multimeters all layed out for display on a table and I was astonished to find that the LCD display on every meter had turned purple.   :o ::)

    One of the multimeters he had was a Fluke 116 in pretty good condition except for the damaged screen so I asked him what he wanted for it, he said eighty bucks and went on to say they are worth a few hundred, I laughed out loud and said "not like that they're not, you need to keep anything with an LCD out of the sun".   :P 8)

    With that he promptly moved everything with a screen into the shade but it was all too little too late, he then said the meter still works, I laughed again and told him that the meter was now stuffed and needed a new LCD which would probably exceed the meters value, some people really have no idea how to care for stuff.   :-BROKE :(

    Ordered 30x 9 pole Male Sub-d headers from China. Today 30x 9 pole FEMALE sub-d headers turned up.  :palm:

    First time I've been disappointed that 30 Females turned up at my door.

    McBryce.

    They identify as male and you've assumed their gender, I can't even...


    Tell that to the mating connectors that seem to identify to the gender they were assigned!

    I went for a walk at around midday today and ended up at the local weekend trash and treasure market so I went in for a bit of a look around. I stumbled across one seller who had a few used multimeters all layed out for display on a table and I was astonished to find that the LCD display on every meter had turned purple.   :o ::)

    One of the multimeters he had was a Fluke 116 in pretty good condition except for the damaged screen so I asked him what he wanted for it, he said eighty bucks and went on to say they are worth a few hundred, I laughed out loud and said "not like that they're not, you need to keep anything with an LCD out of the sun".   :P 8)

    With that he promptly moved everything with a screen into the shade but it was all too little too late, he then said the meter still works, I laughed again and told him that the meter was now stuffed and needed a new LCD which would probably exceed the meters value, some people really have no idea how to care for stuff.   :-BROKE :(
    Do LCD displays get damaged that quickly, though?

    I wouldn't have thought so either but it was a pretty hot and humid day here on Sunday at around 28 celsius with no cloud cover at all and no telling how long they had been exposed to direct sunlight, based on his asking prices I suspect he has probably had them for quite some time.     

    I got the impression from the seller that the problem had only just occurred as he appeared to be unaware of the damaged screens until I brought it to his attention, another seller also had a few meters but he had them situated under a large umbrella so they were mostly in the shade.

    While I admittedly don't know much about the phenomenon, I'd guess that it takes more than a sunny afternoon to damage a meter screen of reasonable quality. Otherwise we'd probably see many more damaged meters around, as people work outside with them too. Maybe he bought an already damaged batch?

    He had a variety of different meters most of which were used so it wasn't a batch thing and he probably just bought them all in a bundled lot from an auction house. I have seen other meters with this problem before and as part of my work we regularly use meters outdoors in direct sunlight but never for any extended period. We might have to sacrifice a meter for science or ask Joe if he has a spare blown one hanging around which he could put to the test.

    In every case that I have experienced the LCD recovers when it cools back to some reasonable temperature.  Wouldn't want to bet a high dollar meter on it, but have watched it happen a lot of times when I lived in Arizona.

    Mmm Space the unending battle  :palm: I think this one and my baby router are moving out of my main shed/workshop and into a tiny (3x3m) studio type of building further down the garden. It is fully lined and waterproof and only houses some 'stuff' at present so a dedicated space for chips, shavings and dust makes sense.

    Good deal if it has most of that capacity. Also shipping for $40 is reasonable considering the weight of the thing (60lb?) and hazardous materials.

    Local Homebase is closing down, so picked a reasonably decent mains drill for £13, and a high security mortice lock  for £6.50 (Normally £35)  Fancied a vertical router (wood, not electrons!) for £26 but not sure I'd use it. Although I have seen some people use them to make PCBs.

    I found some sockets on Ebay to go around and under my desk for £20 each.

    I got four of them and I am going to screw them under my desk.

    I ordered some 5m cords and the glands are the right size and it is easy to swap over.
    https://www.ebay.co.uk/itm/Replacement-power-tool-cable-flex-cord-1-5mm-3-core-rubber-H07RN-F-13A-plug/162595271463 (https://www.ebay.co.uk/itm/Replacement-power-tool-cable-flex-cord-1-5mm-3-core-rubber-H07RN-F-13A-plug/162595271463)

    I got some Amp baskets with the long brackets to go under the sockets and surround the desk.
    https://ampwire.co.uk/product/under-desk-cable-trays/ (https://ampwire.co.uk/product/under-desk-cable-trays/)

    They seem overpriced and cost more on Amazon.
    I couldn't find them selling elsewhere cheaper.
    I spent hours looking but they seem to be what I am looking for.

    Also got some brown 52mm fencing brackets to mount some large network switches under the desk.

    The amount of wires in bedroom are making me sick so I expect this to help.

    Don't 'assume' dimensions from photos ASK before hiring a truck one size to small (and with no tailgate lifter) then driving it several hours each way :palm: Gantry wasn't to bad to drop off the rails and the seller was more than helpful. Unfortunately the Bed and rails now have to come off the table too so it will go through a door.

    My old Creek 4330 is starting to act up and I'm probably going to have to take it out of service for maintenance. As slow as I am to work on stuff that may  take a while so I needed a replacement. The NAD 310 I bought a while back was going to take care of that, but I found a few things I didn't like about it, So I went looking for something else.

    This is what I ended up with. Pretty nice. No complaints so far.

    Due to budget constraints (again) yesterday and today I spent buying what I thought was a very exotic, rare and valuable space to allow building an enclosure for the CNC to go into. Time to get the shoehorn out again  |O

    Yes there is a problem on the other side of the printer enclosure......

    Can't you just move those storage boxes?

    I see there is a compressed air jet to clear dust away from the router bit. But don't see any vacuum dust collection system. Is there one? Because you are going to wish there was, after everything in that room (and any connected rooms) gets covered in fine router wood dust. I've been though that painful learning experience myself.

    I got one of these wee fellows yesterday!
    I have the older mains powered 1 but the cable always seems to be just too short or knocks things over as I try to get into awkward bits or whatever and the re-chargeable one just seems like the best option for me.
    I got the 7.8v one which is the 2nd one up but it has plenty grunt and the battery lasts fine and also has a quick 1hr charge time. If I find myself running out of battery too often i'll get another 1 as a spare to switch out when needed.
    You can get the 10v or even 12v which will really last i feel but the are a bit more ££'s obviosly. I feel the 1 i went with will suit me needs fine  :)

    Yesterday I received a 2KVA (8A) Variac.

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=584399;image)

    It is already heavily modified as of today!  ::)

    Nice!  :-+

    Works very well, the transformer wire is the correct section for 8A (220V) and arrived with no faults unlike some other samples I've read somewhere.

    I've added an output 8A slo-blo fuse, a "Phase OK" warning light and both input and output SCHUKOs for ease of use but keeping the IN/OUT original terminals for versatility.

    I also made a couple of security internal modifications: isolated the central tap in the coil as for me it was too exposed into the frame. Also protected with heat-shrinkable sleeve the big central lever axis because the wiper cable is wrapped around it and, providing it is heavily knurled, I was afraid it will eventually bite the wire isolation and short-circuit to ground.

    The digital voltmeter panel accuracy is adjustable by a trimmer but it was already quite precise.

    So far so good.

    6115A, $37USD from evilBay, mid 80s vintage. It had many of the reported issues, buzzing film cap across the transformer, bad contacts setting the voltage, very dirty PCB, oil oozing out of the clear plastic cable tubes, broken binding parts, and a bad electrolytic capacitor. Even still, it mostly worked when delivered.

    I wouldn't call my work a restoration, but more of a refurbishment. The film cap now is a X2-rated R463N410050N2M, one ceramic became a RDER72J473K3K1H03B, three relatively tiny 100ZLH470MEFC16X31 replaced three top-side caps (of which one failed, EEU-EB2C221 was the fourth cap you see (higher voltage than the manual specified, but lower than the part it replaced), and a 250BXC4.7MEFC8X11.5 across the output terminals.

    I used binding posts that were lying around the house (ugly mismatched ground lug), and sprayed G5 deoxit onto the four voltage decade switches.

    Should I add an EMI line filler? Maybe? Otherwise only outstanding issues are that the milivolt pot doesn't work so well, a missing screw on the back panel, and a lack of feet (3D printing, maybe?).(https://uploads.tapatalk-cdn.com/20181130/ca4158ed745690573a9ccaa530fd1907.jpg)(https://uploads.tapatalk-cdn.com/20181130/39ad0d6c61c46194a0273e3a6d32e717.jpg)

    Today I ordered a new 1TB SSD and a GW Instek MFG-2260M function generator. A new (better) function generator has been on my wish list for a long time. The SSD is to re-install my PC which is a job I'm not looking forward to at all but nowadays 32bit versions of software seem to become rare so it is time to switch.

    Naturally without any manual AND the red/black wires for the power and anemic signal connector inverted !!!
    But it turns on, the blue digits are to die for ;) AND it even measures my scope 1KHz calibration taps (soon I'll even start the generator to see how far does it go, but after I'll rework the input).

    Playing with the front buttons I've got selection from:

    Channel A/B ?!?!?
    Digital filter On/Off
    A number to set:
    IF xxxxxxxx

    Pressing and holding both at power up, displays the firmware version: 2015.11.something

    If somebody has already a manual for it, I will appreciate it.

    I don't know how you would do that buddy. Maybe one of the more experienced guys can tell you how to do that? I have no idea about doing this.
    You could even make a brand new thread asking how to do it, that'll get more exposure I would think too? I'm sure someone here will be able to keep you right on doing it.

    I find myself using it so much it might as well almost be permanently attached to me as I move around the house these days. (trying to catch up on lots of projects over the cold weather months) Of course measuring current without wire removal is just so very useful but also its NCV setting is too. I find myself using it to scan all sorts of devices. Some low voltage devices, like the PS2 keyboard I am typing on, inexplicably turn out to have high voltages present somewhere.  Will need to take it apart at some point to figure out why.

    I got one of those, very happy with it but the decimal point stays in place at each 3rd digit to indicate thousands is annoying. I use it now when I need to use 2 counters only because of it.

    Someone else has posted the link to the manual so I won't bother but will add that these little meters are damn good value for money, they're pretty accurate and have a bunch of features like selectable IF offset (via the 6 pin header on the rear) which makes them useful for building in to radio projects, the ones I've had do generate a bit of RF noise so you need to pay attention to power supply filtering and they can benefit from shielding.

    You will enjoy it buddy but I would recommend doing the 4 wire conversion on the leads. There are a couple videos on YouTube for how to do it. It's easy, even I managed to do it. If you need the links for the videos just post and I will find them for you.

    Yet, another used Siemens beefy inductor, 2 bucks, as I can't bear the thought of the recycler going to salvage the copper inside, so here we go.

    Measured details : DCR = 0.04 Ohm , inductance = 502uH@100Hz and 460uH@100KHz.

    Yep, still don't have any idea what to do with it.  :palm:

    Smaller one -> primary 2x115V, secondary with 2 windings : 15V@0.5A and 9V@1.5A
    Bigger one -> primary 2x115V, secondary with 3 windings : 10V@8.3A, 22V@2.7A and 24V@2.7A

    What a weird secondary voltage windings at the big one that is made in USA.  :-//

    Nice cables! What do you use them for? I haven't seen the connector on the ends of them before.

    The connectors are on the ends are either SMA or 3.5mm precision connectors. They are used for RF work. The cables themselves are built to a guaranteed maximum loss and maximum phase error. The SMA cables are rated to 18 GHz, the 3.5mm cables are rated to 26.5 GHz. You can connect the SMA to the 3.5mm cables. The 3.5mm connectors use an air dielectric instead of PTFE and are built to a higher standard of precision. That also means they are very delicate. Torque wrenches are used for all mating connections. I use them with my 26.5 GHz network and spectrum analyzers.

    I bought a Fluke 101 and case for my toolbag.  I was disappointed in the inaccuracy of my Aneng 8009 on voltages when I checked it with my DMM Check plus.  I still wanted something relatively small and for $40 USD, it's a good enough deal.  I probably should have bought this first instead of the 8009 and the 8008 that I have as a back up.

    GreyWoolfe, this is interesting info; did the Anengs start to drift continuously or were they subjected to an... ahem... "event"?  :-BROKE

    If the former, that says a lot about their build and reliability.

    Actually, no.  The only event they both went through was the well documented mods for the more stable display.  OF course, I received the DMM Check after the mods were done so I don't know if I  :-DMM something up doing the mods, though I doubt it.  C'mon, it's adding a couple of caps and replacing a couple--not hard to do.  The 8008 was much closer than the 8009 but not near as good as my old Fluke 27/FM.  They live a quiet life in my company van as I needed a small multimeter accurate on low ohms reading and they both do it very well.  The only voltages they have been exposed to was the DMM Check.  They are much better than the red HF meters, I found 2 of them NIB with fresh batteries that were an order of magnitude off for what I needed.  Quite embarrassing as this was at a training session which prompted the Aneng purchase.  After more pondering and rumination, I may need to do quick voltage checks including mains and I don't really trust the Anengs for that.  That's what prompted the Fluke purchase.   I will still keep the 8008 as a spare but I may Wildarize the 8009 just for fun.  I haven't used my 2 pound hammer for anything in quite awhile.  I will see if the voices in my head tell me to keep it intact. >:D

    Actually bought a couple of weeks ago. Good investment for about $150 delivered (amazon).

    Cheap vna that has good reviews and indeed it does work very well for testing out antenna prototypes.

    Picture is of a prototype moxon antenna for lora at nominal 910MHz.

    I also purchased Matlab home (about $150) and the antenna plug in for $50. I have a PCB prototype layout of a moxon antenna that I'll have to send it to a cheap PCB fab when I get a chance.

    cheers,

The jaws align correctly, and I passed 3A through them and got a 50mV drop for a 4 ft length. Not bad. I don't think I'll ever use them for more than 5A so I'm happy.

    The FLuke 101 hit my hot little hands yesterday.  The small size is perfect.  It meets specs easily with the DMM Check plus.  Down side is the crappy pvc test leads.  Waddya want for $40?  It is more accurate with the Brymen test leads that I intend to use it with than the OEM leads.  The cheap case from evilBay is on the way.  Better storage solution than the drawstring bag the Aneng came in that I am using for now.  I've seen a lot of people give it bad reviews because of no current rating.  Did they not read the specs?  Also stars off for no stand.  Really?  If it doesn't meet your needs, don't buy it and give it a bad review.  If you didn't buy it, don't give it a review of any kind.

    I had to order overseas for a bit more as I can't find them selling here.
    On Amazon and Anker.com they sell them elsewhere when comparing the two parts of the site but not in England.

    I have already got a few and they seem quite reliable.

    Do you actually need its higher safety ratings? If so, it's a perfect little meter. If not, and only be used as an electronic meter, Sanwa PM300 is a better choice. Dave has it on sale for $47 (AUD 65) at this moment.

    I have the PM300, and I had the F101 as well. I would say the PM300 is better built in terms of polishing details, and the F101 is better built in terms of robustness.

    Both can't measure current, but that's expected for the size and safety ratings.

    FYI, if an ultra thin pocket meter is desired, Sanwa PM3 is also an option. It's not for mains, but if you only do Arduino stuff or you need a tiny meter in your glove box, it's not a bad idea. I have it in my computer bag, along with my Analog Discovery and Owon VDS3102L. Unless specifically requested, those gears are all what I bring to debug boards for friends at their location.

    No real need for the higher safety ratings.  Low resistance measurements for a field replaceable unit--15R good, 30R bad and Less than 1R for thermocouple good, over 1R bad per service manual.  That is the limit on 'electronics" and the 101 works just fine.  Possibly DCV and checking mains to make sure outlets the equipment in the field is plugged into are working.  I have a very short service window-check the FRU-bad, replace.  If the equipment still doesn't work, replace the equipment, no time for dinking around.  I have no need for current with the meter.  I didn't really want a real pocket meter, I like the leads unattached.  To me, they also feel a little cheesy but my only experience with a pocket meter was a Radio Shack pocket meter.  The robustness is a plus, it will get jounced around in my toolbag.  I wanted small but not necessarily as small as the Sanwa. 

    There are a ton of options out there, it comes down to need and personal preference.  It's a Fluke, the 101 does what I need, it's priced right, it has overall good reviews and Amazon prime had it in the mailbox on Saturday after ordering Thursday night.  Besides, if it doesn't last, I will just bug my boss that I need a new meter and will let the company pay for the 2nd one.

I think it has maybe rotated it's last unless I decide in the future to spend a chunk of time on it. I remember it when he was Electrical Contracting so it was more than 42 years ago old and closer to 50 I suspect .....

    That's 1 nice looking scope buddy!

    I'm sure you'll have plenty good times getting to grips with it as i'm sure it does loads of cool things way above my knowledge level! It even just looks like a quality instrument never mind when you start it up and put it to work I bet!

    I only have the Rigol 1054z and even that does too much for me, i'm still learning about it and the things it can do. It is nice to have the extra features and stuff though.

    I think too, it for sure makes a better day when you have nice quality equipment to use when either working on things or like me just doing  hobby stuff.

    I'm sure you'll enjoy it loads!  :-+

    Ha ha!

    I have a couple other things from the same brand. Tweezers which are great, they are very sharp and stay poker straight and most importantly they are very very robust even after a few months of using them.
    I have a couple of sets of their long nose pliers too, snipe nose and also the just plain long nose which are the same as the tweezers and scissors. I would highly recommend any of the stuff I have from them, no complaints what's so ever. I will also buy more of their range in the future as I go along.
    They are a wee bit more expensive but not too much for the quality they provide. I find CK quite a good brand too for the price but Engineer is just a bit stronger I feel.

    I hope so. I have been looking at it before but was not prepared to pay €6000 for it. My first thought about the £400 was that it must be a wreck, but it doesn't seem to have had much use. Clean, no scratches and no stickers. Perfect BNC connectors and very little dust inside even though it has a big fan blowing unfiltered air into the enclosure.

    Spectacular startup when it performs power on tests and clicks its relays. It has 44!

    Nice seller (MCS Test Equipment). The unit passed their cal lab for a check out before shipping and the also included an industrial class CF card. Didn't expect that considering the price.

    I don't have it yet so I'm still considering my options. The 1143A  seems to be very hard to get and absurdly expensive. The 1142A seems to go for a good price now and then though. So if I can get one of these cheap, I'd go this way. For the beginning, I will apply the +/-17V from a lab supply. Anyway, there was a thread here a while ago with manual/schematics and pinning of the connector.

    [EDIT]
    I just noticed that the 1142A is not just the single channel version of the 1143A . So I guess this means DIY in the long run.

    Another 10 RFM96 radios arrived. Amazing how cheap they are and how well the Lora technology works for long distance at low power.

    I have a small STM32F0xx board I designed that interfaces to the radios directly and brings out a u.fl connector for the antenna connection.

    Getting quite a collection of sma connectors/cables/etc to hook things up together as well.

    A quick test was 1.5km line of sight. RSSI was about -80dB with a total budget of about -140dB. Over the next weeks I'll do some real testing over longer ranges, it should have no issue in open line of sight conditions reaching 30-40km which is my goal for very low data rate telemetry.

    Lora is an impressive technology and you can trade off packet transmit time for SNR/range. At the higher link budget levels, overall data rate gets down to just 10's or 100's of bits per second. At those rates you need to start looking at tighter tolerance crystals and then to TCXO modules. These cheap modules use regular crystals but you can easily remove (hot air) and replace with known quality crystals from a known distributor that are in the 10ppm range. Semtech (the chip maker) has a reasonable link budget calculator where you can see various tradeoffs (snr/rate/crystal tolerance).

    Current consumption of the module depends on the power level you are transmitting at (you can adjust output in 1dB steps). Overall consumption depends on transmit and receive duty cycle. The module can also be flipped into sleep mode and then it's down in the uA range. At full output and during the transmit phase it will range up to 120mA (at 3.3V), that's a 20dB output with the power amp turned full on. The tests I were doing were at 13dB and around 30mA transmit current.

    The biggest task was porting the radiohead code to a non-arduino and non c++ environment - but that was just a day or so of code slashing to get to the core routines that are actually necessary. A worthwhile process to fully understand the command/control code for the SX1276 (the chip that is used/relabeled) on the module. I've used some of the Digi 900HP style radios before, so already had a decent understanding of the broadcast/unicast/routing schemes that some radio protocols use.

    cheers,

    I recently bought a spare desoldering gun and some small fast normally closed air valves to upgrade my zd-917 desoldering station - started work on it yesterday before family duties got in the way

    I just need to wire the switch to the valve and wire the vacuum pump to always on. This should give me a nice fast suction and be a nice upgrade to my cheap station.

    After weighing up the performance vs. price, I decided to get one of these (HTi HT-18 220x160 thermal imaging camera) rather than a secondhand Flir. Hasn't arrived yet, but hopefully it will arrive before/during the Christmas break so I have some time to explore it. I've seen all the hacking options, but I intend to leave this in its original state. If I like it enough, I may get a second one for a hack project. I still have a Lepton sensor from a Flir One here that I never got around messing with.

    I bought a couple of 'helping hands' clones of the nice GRS ones, the GRS are too hard to find here in Australia, and would probably be close to 100 dollarydoos landed. The clones from Taobao work out to be around $20 plus about $10 each for shipping (they are ~1kg).

    Quality control is ehhhh as you'd expect, one of my units doesn't sit flat on the desk because the bolt underneath is too long, but that's nothing a set of rubber feet cant fix.

    I wanted this particular style because I can tighten the swivel points to kind of lock them in place, the springs in the jaws are strong enough, and the jaws themselves are made of metal with serrations (they will scuff up soldermask easy so be careful).

    All in all I'm pretty happy but they're still a touch too expensive to give a solid recommendation to others. I want to try a few Panavise next to hold bigger items.

    Meanwhile my Keysight scope went to repair for the fourth time >:(.

    The first time the device failed to boot due to NAND corruption.
    The second and third time the device boots fine, but crashed randomly, and I fixed it myself by reflashing it. Same NAND corruption.
    This time the device shorted itself for whatever reason. The power supply makes the typical overload hiccup noise, and nothing comes on.

    The 6000X scope?
    Since I read your horror stories, I am afraid, each time I to turn my 6000X scope on.

    Yeah, and another item for my collection.
    Wasn't ultimately cheap but for some reason the prices for current clamps on eBay are insane. Like people want 770€ for a Chauvin Arnaux E3N even though you could get a brand new one for 341€.
    Anyway, the PR 30 is said to be effectively unused, so I guess 150€ is an OK price for something that is more or less the same as a Fluke i30s (which currently sells for >= 600€ new).

    For schematics and board design 9.2 is OK indeed and I'm really proficient & happy  with Orcad Layout but I'm starting to need 3D output support. I'm wasting a lot of time making drawings from a circuit board and/or making physical models which then need to be re-drawn by the people doing the mechanical side of things. Having a 3D model which can be dropped into a 3D package would be a big win. Also the high-speed signal and cross-talk simulation is a handy add-on for the designs that need it.

    Much to the chagrin of many, bought a VICI VC8145 ( I can hear the ambulances running now ) for $160 AUD.

    Already written the software for linux to tie it in with Openbroadcaster/YouTube, logging and eventually in to my Boardview suite.

    It's little more than a glorified handheld with a 9V power brick inside but it has fast continuity and for the work it'll be doing it's already an overkill.

    I think the next meter will likely be an Agilent or Fluke, however for now, this covers the needs.

    I'd call this a win-win.  You got a great cheap instrument.  The commercial lab probably couldn't do the same repair and sell it in good conscience.  They would have had to do the whole board replacement.  Non-economic.  So they got something and you did too.

    Got myself a Keithley 181. Reason ? Just because.
    Works perfectly. Its just hard to find the right plug for the mV input. I got one, but I want another one. Plus the mV connector on the 181 is gold plated. From what I read in a repair thread for the 181 here, it should be silver plated ?
    I will change the filter capacitors, just for good measure and calibrate it. Now I need a KVD....

    Just remember those contacts in there are not rated for continuous operation at 10A, and also they are not fail safe when disconnecting into a high current. They tend to weld together under heavy load, so best used in conjunction with a sensitive 16A AC1 rated contactor. Those at least will, when paired with the appropriate overload, provide good protection. Hope you also got some LED power on indicators to go with them.
    The contactor should not be operated correctly, it is a safety button with locking, these buttons are used to control the circuit breaker trip coil - the most reliable disconnection -   - the coil acts on the circuit breaker locking mechanism

    Wurth 885050 capacitor kit. $140 on a kit of MLCCs |O.
    Normally I would never waste my money in such a way, but this is an exception.
    I didn't have time to finalize my calculations, and DigiKey cuts off in 20 minutes for X-mas eve (1:00 PM EDT, as I was told on the phone).
    So I have to order an all-inclusive kit just for the one part I need immediately.

    Along with $100 worth of other parts, namely some GaN transistors and some passives, and some OPAMPs.
    Fast class-D envelope tracking is interesting.

    if you buy from digikey, do you still get lifetime free refills?

    Hi all, I bought the ZD-8915 and JBC CD-2BE. Yeaahhhhh. The ZD-8915 I ran through some of it's paces and it works, so far, very well! The glass tube is a night mare to take out. Now in search of 1 eurocent coins as we never had those in the Netherlands. A US dime or perhaps some other copper (plated) smaller coins will do the trick as the mid-point stopper and solder catcher. I've now squeezed in from an previous de-soldering equipment (Philips rebranded SEM/FTM technologies). The JBC I did not try yet. Only connected it, played with the super fast heat and sleep mode. And of course updated the software. Very happy so far with these purchases and will definitely try out some other active tips for the JBC from other sources (.... express). Should I post pictures?

    After weighing up the performance vs. price, I decided to get one of these (HTi HT-18 220x160 thermal imaging camera) rather than a secondhand Flir. Hasn't arrived yet, but hopefully it will arrive before/during the Christmas break so I have some time to explore it. I've seen all the hacking options, but I intend to leave this in its original state. If I like it enough, I may get a second one for a hack project. I still have a Lepton sensor from a Flir One here that I never got around messing with.

    McBryce.

    The camera arrived today and I'm duly impressed. I can highly recommend this to anyone looking to add a Thermal camera to their TEA affliction required test equipment collection.

    A few quick random ones....

    The first one is an Arduino Uno R3 taken from approx 15cm. The second one is my new monitor (Asus VA327H) taken from 1.5m. Both taken with the least amount of real video mixed in.
    Maybe we need to start a proper thread for the HT-18 (if there isn't one already).

    It's definitely noisier when you go below the recommended focal distance (500mm), but at distances that it can focus I'd put it above Seek and around the same as Flir, however, I suspect Flir do some pre-processing trickery before sending it to the screen. And... A Flir (even with lower resolution) will cost a lot more than the €299 that the HT-18 costs.

    - An army of AUGAT sockets, like 3 heavy divisions of 24 pins and some fast 16 pins along with (non-pictured) super heavy 40 and 28 pins, costed all together less then then 15EUR.
    - A OCXO upgrade PCB for HP5385A from our forum member Miti and some 10MHz OCXOs from the famous Chinese seller Queenie ;). The OCXO are still burning happily and I'm waiting for their 1000 hours to start measuring them.
    - Some 16,384MHz crystals, 5K ceramic trimpots along with some 280K reasonable stable resistors and some PTFE soldering points for my never ending poor-man calibrator project.
    - An unexpected nice surprise, one forum member send me some famous voltage reference boards for the cost of shipping, thanks you know who you are  ^-^ and if you reach Mannheim you WILL get drunk  ;D , I even started one of the LM399 (the other one it's a bit strange, the heater works, but the diode has a very stable but just 1/10 of the normal output voltage  :-// ?!?). The LTZ1000 are still on the "too poor to get the LTZ parts" lane.
    - A (non-pictured) PREMA 6000 multimeter, advertised as with scanner and defective, got one perfectly working and with no scanner, no complaints here  :-DD.
    - Ca. 3Kg of NOS resistors, 0,125-2W, not particularly high quality, but extremely cheap and not chinesified (terminal are thick and copper, usw).
    - A Kelvin-Varley voltage divider DEKAPOT DP1211, see the Metrology thread for pictures and a tear-down, thanks again Ulf for helping with the shipping, the beers are waiting  :-+.


    Actually today, being pissed off that I've lost on of my monocular loupes:

    Had an arrival of a Heatshrink pack so I needed to make a better storage solution for it. Required the purchase of another bottle of Glenfiddich and consumption of a bit of the contents while the printer made the joiners. #winwin

    The little baggy of leftovers will finish up in a drawer at this stage. This tree should stop multiple bits of the same colour or diameter getting started 'in theory'.

    I might add another hole or two at intermediate heights so the bits sit closer to the tube.


    edit - added a more complete shot including hotsnotted joiners and holes.

    Why didn't you make the lid a cup to hold all the short bits?

    I did think about it. Currently the baggy is sitting under the lid as the tube is fairly full so it doesn't drop down. Maybe a MK II Lid is needed  :)

    The holes are well worth it sorting through a mixed tube to get to the started lengths just doesn't work.

    An emergency button

    Hopefully it's the last time I will deal unsafely with live 220Vac voltages...  :-X

    Just remember those contacts in there are not rated for continuous operation at 10A, and also they are not fail safe when disconnecting into a high current. They tend to weld together under heavy load, so best used in conjunction with a sensitive 16A AC1 rated contactor. Those at least will, when paired with the appropriate overload, provide good protection. Hope you also got some LED power on indicators to go with them.
    The contactor should not be operated correctly, it is a safety button with locking, these buttons are used to control the circuit breaker trip coil - the most reliable disconnection -   - the coil acts on the circuit breaker locking mechanism

    Correct, these emergency stop buttons are only rated for the coil current only and should never ever be used as a means of breaking the mains power supply directly, only via a suitably rated contactor

    I know this is a week ago but a pair of very similar ones arrived in the mail today. Quick non destructive teardown for information. Allegedly 15A rated  :-DD Maybe 3A would be closer and even then ? This pair is going on my CNC via a properly rated relay to the power supply/vfd.

    Hopefully a contactor, not a relay as relays tends to have silver contacts and can evaporate with arcing caused by motor currents. Contractors on the hand gave silver oxide cadium contacts to withstand the arcing.

    It is in this case it is a contactor I salvaged out of a coffee machine they are designed to cycle 20-30 times an hour for years. Contacts unknown but it is a 3phase one so it should do fine.

    The thing that comes to mind with that is, isn't a coffee maker typically pretty much a purely resistive load?  It's likely not an issue, but might be something to consider.  What sort of load will the CNC machine present - something more inductive and potentially arcy-sparky?

    Power Supply and a VFD on the Head so no harsh on/off and under 3kW total (<15A).

    Espresso machines are hard on or off and the contacts are 20A rated each x 3 so cruising in this case. I have never seen one of these fail in a modern machine and some are 7.5kW+ running the same contactor in a lot of cases.

    I would tend to agree with you Pat. I used to look after many vending machines including coffee makers and they are mainly resistive loads. I have been called out to so many alleged faulty gear call calls over the years where people who really should know better have built huge great motor control panels for production process that have cost thousands of pounds in damages because the so called professionals used hundreds of relays to control motors on automation of production plants that have failed and ground the entire factory to a halt as a result. Replacing the relays with proper contactors cured the problem permanently and the same panels were still in daily use when they closed the factory many years later and demolished it to make way for housing and a retail park and the only difference is the contact material, a small but vital detail to get right.

    That may be so, but I would do my homework on the contactor / relay part number that you're using to make sure what the contact material is because contactor contacts tend to be rated as AC4 (inching and plugging as you would do on a crane) which is the most difficult load to switch on because of the massive inrush currents, switching off is not so hard to do.

    Check the following link and look at the table there which details the massive inrush currents that contractors have to handle (AC2, AC3 and AC4 ratings, AC1 rating can be handled in most cases by a relay if there is very little inductive loading on the circuit.

    Worst case here is likely to be a tool crashing into the bed which already has proximity sensors on it and disables the VFD. VFD failure and magic smoke release to short will likely trigger the ELCB or fuse board breaker before I can get to the stop switch.

    So the emergency stops and contactor are more belts and braces to keep me happy I can manually kill it rather then yank the plug out of the wall (like its former owner used to have available) or if I lift the lid to do something with fleshy bits near the pointy bits keep the spindle from firing up.  :o

    Safety buttons on the industrial trigger are mechanically solved - by pressing, the contacts disconnect mechanically, not electrically (with the exception of security coils circuit breakers and switches). With electrical disconnection, this is considered to be a normal "Stop" button whatever its shape.

    This is a magnetic ferrite core memory plane.
    ("Plane" seems to be the correct term for this.)
    I purchased this on ebay from the Russian Federation for $35 including shipping. The shipping time from Russia to the USA was about one week. I didn't have 100% confidance that it would arrive, but it did.
     
    This magnetic core memory plane was made in the USSR in 1970s.
    It is a 32x32 core memory plane that stores 1024 bits (128 bytes) of data.
    The plane outside dimensions are 4.4" x 4.4".
    This plane is one of 20 planes forming a magnetic core memory block. The capacity of the whole block is 2560 bytes.

    I bought a second hand book from a US seller in Baltimore MD (via abebooks.com) It's Vol 2 for a Vol 1 I've had for years.
    Nice price: US$ 18.79 plus postage US$ 8.98

    The packing was ... strange.

    The bookshop put it in what is effectively a brown paper bag. The paper is tough, but stiff cardboard it isn't. The bag inside surface has a tacky coating, so the book doesn't slide around and excess volume of the bag sticks to the other side. Overall volume is basically the same as the book. But there's no resistance to impacts at all.

    They put a customs declaration and address label on that bag.

    Then someone in LA CA put that in a giant USPS plastic sack, dimensions flat: 1m x 0.7m.  Wiretied the neck of the sack, with another address label. 'INTL SURFACE AIR LIFT'
    That has a tick box for "Books/sheet music" but it isn't ticked.

    And that's how it arrived.  A book in a bag in a giant sack. This goes up there among the oddest packings I've ever received.
    The book is hardback and survived more or less, but is sort of 'rounded on the corners.'

    The sack seems pretty useful. Light and strong. Maybe for beach/snorkelling gear. But why was it added?

    The city of San Jose (which is very flat, no hills like SF) recently let a local company set up a system to allow people to rent (brightly colored, highly visible) electric scooters in the downtown area and drop them off at their destinations. Similar to the pictured but stand up, no seat. People can use them on sidewalks, legally. They have generally been well received, I gather. Saves people visiting a lot of time.

    Nice 1 on the etwow.  :-+

    I did think about the weight of the Viper which I guess is around 25-30Kg although the shipping weight is stated 20Kg on the shipping label. I hope the shipping weight is correct and I am wrong but I don't think so.
    If it is too heavy I will bolt a couple small stabilizers on to the rear end so I can fold it up and then pull it more like a trolly sort of thing as opposed to carry it like a bag. We'll see.
    I had the petrol "GO PED" years ago and it really was a laugh so I kinda know what to expect with this even if this will be so much more powerful and quite a bit faster top end.
    The thing I found with pot holes and stuff with my GO PED was it would skim over most smaller stuff and the bigger ones were big enough to see long before you needed to get on the anchors or go around them. You do need to be very vigilant though, a seconds lost concentration could be the difference between a good day out or a skin graft.
    The petrol GO PED I owned years ago had much smaller wheels than the Viper has and I found that to be ok so long as you didn't push yours or the machines capabilities to much beyond what was safe.

    The the last model (https://www.eevblog.com/forum/testgear/bg7tbl-gpsdo-master-reference/msg1473322/#msg1473322) (2017-12-16) of a BG7BL GPSDO. (Look at the eevblog thread of BG7TBL GPSDOs (https://www.eevblog.com/forum/testgear/bg7tbl-gpsdo-master-reference/).)

    Some more (all together 10) OCXOs:
    - Trimble 34310-T 10MHz 12V 50*50*38mm sine wave OCXO (double oven, I think)
    - Trimble 65256 10MHz 12V 51*51*15mm sine wave OCXO (as a possible GPSDO spare part, see above..   :palm: )
    - Oscilloquartz 8663-XS 10Mhz 12V sine wave OCXO
    - Morion MV89A double oven 10MHz 12V sine wave OCXO

    And a 10MHz rubidium reference, a Spectratime LPFRS-01 (like in this repair thread (https://www.eevblog.com/forum/repair/repair-temexspectratime-lpfrslpro-10mhz-rb-generator-(drifting-like-mad)/msg824382/#msg824382)).
    This unit is still well documented by its manufacturer (https://www.spectratime.com/products/isource/rubidium/LPFRS/), that's a big plus for me.   :-+

    Funny that you should show these as I’ve also just got a pair like those for ferrules plus another crimping tool for fork connectors and the like.

    I’ve had a look around but couldn’t find out if my (fairly cheap) fork connectors are suitable for 240v (~5 amps) mains use though ...

    I recently also bought the ferrule and spade/fork/ring crimp kit. From china.
    But the crimps all look shiny, and all other crimps I have ever seen are matte. This feels cheap, and I doubt the capabilities of them. They also weigh significantly less.

    Buyer beware.

    There are many crimping tools out there that look like they should be OK.
    But the difference between a sloppy generic crimper and the proper dimensions is night and day.
    Even if the sloppy generic crimper looks superior.

    The video is nice but nothing. Crimping pliers without conversion are useless, the only problem - bought inappropriate pliers.
    Crimping pliers only with gear - great attention has to be paid to marking the jaws - crimping pliers on video are for non-insulated car connectors - FAST-ON. It is easy to see the gap at wire = wide jaw = deformation = can not be used for displayed connectors  :palm:

    If I recall correctly, the off-road quad is somewhere around 5 k€ (8 kAUD), and the semi-recumbent a bit over 3 k€ (5 kAUD).  Definitely worth the price, I hear.

    The SN-28B is the most common crimper sold in China expressly labeled for “DuPont” terminals. So he bought exactly what the vendors say to buy for the application in question!

    I have a few Chinese crimpers, and none are very good. Regardless of what type of terminal they’re for, the precision of the jaws is too poor, and produces unpredictable results (or predictably bad ones).

    Crimping pliers with a gear have a bigger push - thus a stronger wire capture.

    I have several interchangeable jaws, they look the same - each crimp differently - depends on the initial shape of the connector - core clamping ratio and wire sheath (varies with the length of the facets / for one wire, for multiple wires,  wire size) - standard - AWG / SWG / mm2 - there is much variation.
    Chinese crimping pliers stand in CZ 300,- _ 700,- CZK, High quality pliers (Knipex, Wiha .....) 1500, - _ 18000, - CZK by type and design.
    I use Chinese pliers but good jaws - after a small adjustment it works. Pliers for data cables can not be edited - I have the original 3800, - CZK

    Pulled the trigger on one of these bad boys!  >:D

    So it arrived yesterday! Man is it quick! REALLY quick!

    It wheelspins and wheelies all over the shop if you think it's a silly wee kids toy to be abused and not a very torquey wee beast that will throw you as quick as look at you if you don't go easy on the "GO" trigger and keep the power turned down!
    It can be driven with relative ease if you select 1st speed, single motor and set it to "eco" mode, anything above that and you have to be careful on the trigger!
    It has 3 speed settings, 1, 2 and 3 strangely enough  :) It has single and dual motor settings and an "eco" and "turbo" mode setting too.
    Top speed, dual motor and set to "turbo" and it's scary! You need to see this to believe how fast this wee thing can move! It obviously doesn't have a turbo but "eco" is around half power and "turbo" is full power. You can also set it to only power from the rear wheel which is 1000w or both front and rear which is 2000w.
    Single motor, 1st speed and "eco" mode is nice. Dual motor 3rd speed and "turbo" mode is totally wild!
    Single motor, 2nd speed and "eco" mode is nice on the bottom end but top end of that will get you to 40 Kph and your bum starts clenching as it is very torquey even right up to top end!
    I may post a couple videos once I get used to it properly.

    I would recommend it for getting around so long as you don't get above your skill level and wear the proper safety gear. So far as pot holes and stuff the little ones really are no problem but the bigger ones you need to skirt around. It's similar to driving a fast car or bike but just on a much smaller scale. You don't have to roast it... but you can!  >:D

    I finally got my first DC electronic load. It was quite cheap for a 400w model, and the fan is temperature controlled.
    I bought it from eBay (look for KP184). 150v / 40A /400w. It is easy to use (not like some BK precision power supply if you remember the video).  ;D

    I tested it @30A with my 1000w power supply and the cables started to get warm. Absolute coolness.  8)

    well Amazon indicates this :

    Note: about the BNC interface function, please know the follow function of BNC before you use this Extended function. If the voltage measurement is selected as the remote measurement (VOLTAGE REMOTE SENSE) in the menu settings, the BNC connector on the front panel must draw two wires to the positive and negative terminals of the measured voltage, otherwise the voltage measurement and display There will be inaccuracies in the error, especially when the load is loaded

    There needs to be a short back story to this.

    When I graduated from college, the first job I had was as a field engineer for a small but somewhat well-known process control and measurement company.  They had some interesting gear: strip chart recorders, temperature monitors with LED displays, pH and thermocouple hardware.  But ultimately, I realized the job was a dead end for my engineering training so I went somewhere else.

    As a tip of the hat to my old company, I decided that owning a small memento would be a nice thing, and I could legitimately say it was something I could have had back in those days.  Found this on the Bay for $20 and decided it was too cool to pass up.  It has about a century's worth of dirt and grime on it, and there's at least one duff connection in the wiring, but once it gets cleaned up it will be a nice thing to have sitting on the lab bench.  I did manage to test the 1-10 Ω range and it was definitely within 1% accuracy.

    Believe it or not, we had plenty of equipment both in our repair shop and in customer installations from the 1920s (this was 1970).  One of the recorders we had to maintain was a mechanical potentiometer-based unit with a Weston cell as the reference voltage for its thermocouple.  Even though the newer electrical potentiometer with wire slide had been introduced years earlier, many customers felt it unnecessary to replace a unit which had been running reliably for decades.

    I have no idea how old our Weston cells and standard resistors were, but the design was essentially unchanged since the company was founded and they were made before the little graphical "L&N" logo was created.  The service guys still used the old-style potentiometer/galvanometer to calibrate the installations, because they trusted it implicitly.   ???

    Nice purchase, Terra. I bought a NOS years ago that is less sophisticated but at least has a built-in power supply.

    Center ground power jack! I blew up many things with those evil power supplies |O.
    The most recent victim was an LTP2884 USB isolator.
    These things are nasty indeed. I am not sure if the Japanese started this trend, but their vintage music brands (Roland, Casio, Korg, Yamaha) all use center negative. On an ancient Casio keyboard, the power supply that came with it even had a switch to change both voltages and polarity - a disaster waiting to happen. My dad quickly wrapped all that in insulating tape to prevent any one of us kids from changing it.

    Also, with the recent addition of an E36313A, this means I finally have a full-Keysight bench.

    Joking aside, wouldn't aluminium or copper tape on the inside of the enclosure, perhaps with a coat of lacquer or nonconductive tape to avoid accidental shorts, actually help?  Assuming it is not radiating off the wires and such.

    The vfd window is the culprit.
    Transparent EMI shielding, then?  Perhaps an ITO film over it?

    (Just wondering, in case I have a similar problem one day; I do use small OLED displays, and it may bite me in the butt.  Would be interesting to know if ITO or similar conductive film works, or if display/device replacement is the only real option.)

    Well, the stapler was on sale and I'd been meaning to buy a good one for years. All I had until now was a "Little Goliath", which is decent for its size though it struggles to staple more than a few sheets at once. But yeah, I chose the red color because of the movie.

    A HP 85047A (S parameter test set) to replace a '46A that somebody had buggered about with (Electronic transfer switch had been replaced with a mechanical one, fine until you want S12 AND S21 at the same time!).

    Now I just need to suss out how to hack the 8753C so it enables the 6GHz mode with the multiplier in the '47A and life will be good (Until I then discover that my APC cal kit is not good to 6GHz!).

    It seems to be functioning, now just need to wait for the VNA to warm up before tying to calibrate.

    I have a lot of Xcelite 99 series bits.  I have wanted a ratcheting driver.  I found this one at a hamfest that was not functional and the guy was asking $50 for it.  I did some looking again yesterday and found it on Amazon for $55 and is supposedly in stock.  Arrival is supposed to be Feb 8th.  We will see.

    I received this microphone element and earphone element just thrown into a poly bag.
    They arrived with the microphone stuck to the magnet in the earphone element.
    I complained to the vendor (FullCompass) 
    And I am going to complain again if the earphone element doesn't work.

    I bought a new wireless router. It should get delivered today.

    https://www.tp-link.com/us/products/details/TL-WR841N.html (https://www.tp-link.com/us/products/details/TL-WR841N.html)

    I've been using a Rosewill for years now which recently has started dropping the WiFi connection. It only happens occasionally, but I'm guessing it'll just get worse. That's how it went with its predecessor, a Linksys WRT-54 something. I suppose it could be the wireless adapter in the PC and not the router, don't know really because to reconnect I always have to reboot both.

    I've had an Edgerouter-X sitting around for over a year that I bought just because it was on sale, but it has no wireless capability. Ubiquiti has access points you can add, but they're expensive and have other drawbacks. So I'm hoping I can somehow get this TP Link to do the same thing but much more cheaply. At $19.99 shipping included, if it doesn't work I haven't lost much.

    After about four years of continuous work I had some weirdness and connection drops with my router, only to find its plugpack was slowly giving up (it was enclosed with lots of equipment in a quite hot environment). I ended up replacing it with one of the high quality ones I had and it has been steady since then (five years ago).

    I just bought another 2 used Xcelite 991R ratcheting handles like the one in a previous post.  They come with some crusty hex drivers which will promptly get pitched as I have far more of them than I need and some nut drivers.  Even has a 30 day return.  All for the price shipped I paid for the new one.  Two handles will go in my toolbag for work and one will be kept in the house.  This will give the excuse to bring some of the drivers out of my van and use them on my workbench.

    Just got given one of these. A CI-94 Oscilloscope from Russia (1984). It's in perfect physical condition, looks like it was just taken out of the box, but I won't be turning it on until I've checked replaced those Russian electrolytics from the 80's. Strangely, the early ones (including the one I got) used a DIN connection for the probe instead of BNC.
    Difficult to see in the picture (not my actually device), but it's tiny, the front is only 9cm x 18cm!

    They have machines to help. Assuming a good surface to work on I'd guess it'd take an hour to get all those pins depackaged, even if you had someone on minimum wage it would be cheaper to call them and get them to deliver another set packaged less stupidly.

    Sold as fully working, came with battery contamination / corrosion, higher  \$\Omega\$ ranges false and 10's of mV DC offset. Luckily it was cheap enough to be worth it even after spending 3 hours decontaminating PCB and reworking tracks / vias. Appears to be saved and is only waiting a new battery holder now.
    It will be fed lithium cells only!

    This may not be a good idea. Fresh Lithium cells start off at 1.8V and can cause problems in low current applications because the voltage doesn't immediately droop to 1.5V. Dave's 121GW shouldn't be used with fresh Lithium cells because of this. Your one might be similar. Hard to tell though without spending a lot of time reverse engineering it.

    Some low self discharge NiMH batteries like the Eneloops or the rebranded Eneloops like the IKEA LADDA are a better choice IMO and cheaper.

    Received a box containing two Agilent 66319D, bought for almost nothing. I bought them unseen for use as spare parts for the 66319D I already have, but now I realize that I can't use them for that.

    The first one I unpacked is missing a foot and the knob, have problems powering on sometimes and needs calibration. Probably easy to fix.

    The second one is squeaky clean both outside and inside and seems to work just fine.

    So instead of spare parts I will soon have three working 66319D. That was not the plan.

    This may not be a good idea. Fresh Lithium cells start off at 1.8V and can cause problems in low current applications because the voltage doesn't immediately droop to 1.5V. Dave's 121GW shouldn't be used with fresh Lithium cells because of this. Your one might be similar. Hard to tell though without spending a lot of time reverse engineering it.

    Some low self discharge NiMH batteries like the Eneloops or the rebranded Eneloops like the IKEA LADDA are a better choice IMO and cheaper.

    Thanks for the tip, I wasn't aware of this kind of problem. I have tried it on Lithiums and not found any issues, a MAX856 is used as step-up to 5V in this meter.
    The DMM's internal battery measurement reports the (new) Lithium cells as 3.3V, that's lower than the 3.6V measured externally.

    Got a grinder, "Proxxon Tellerschleifgerät TG 125/E". Nice little tool.

    *disc sander. A grinder is the thing with hard discs (like a Winkelschleifer) or stone (like the grinders for sharpening blades).

    How do you like proxxon’s other tools, like the sander? So far I just have a proxxon “dremel” (IBS/E and the MB200 drill stand).

    Bought an R&S NGPE supply. Didn't work because some caps were shorted, and possibly bad regulators. Because of that the +15V rail was low and unit thought it was pulling about 50A at all times. In the process of fixing it by replacing every tantalum capacitor and all of the +15V regulators. Also had no mains cable so I had to find the right connector(4 pin circular amphenol connector) and make a cable. The amps panel meter is cracked but I can't seem to find any part number or a similar style. I have every board out of the unit and all the tantalums removed and all ready to be replaced. Parts don't come for a couple days though. After that hopefully it'll work.

    Totally get rid of the two blue elcos on the middle boards, I never seen a case when they don't create problems.

    What sort of problems? The power unit also uses some Philips HP caps but much higher voltage ratings. The ones on the smaller boards are for the split +15 / -15 rails.

    I was going to convert this HP Battery module to LiPo's but decided to swap out the 2500 long dead NiCads for 'allegedly' 10000mAh NiMh instead to keep the other mods to a minimum. Under $4 USD each delivered on special so also a chunk cheaper than LiPo's.

    Can't read the type number anymore, it's scratched, but I have a small dremel from Proxxon as well with a stand. Works pretty good for drilling small holes (a few millimeters) or cutting traces. But for bigger holes I need my drill press.

    Having a bit of trouble finding info on it though, it's part number MC833X4-006W and cross references to HP part number 1813-0644.

    I bought an Advantest R3131A Spectrum Analyzer 9kHz - 3GHz  off of EBay for $165 shipped. Doesn't have TG option but the price was right.
    I had the seller try and run self test but he reported the keyboard was not responding to inputs.  Hopefully I can use GPIB adapter and labview to get it responding remotely.  In addition, I bought a few attenuators and Type N - bnc adapters to test it, but have trouble finding a cheap 3GHz source to test it with.  My Wavetek 288 function gen goes up to 20MHz with AM/FM and will be fun to play with.

    I was going to do the same thing to an instrument that had a lot of dead NiCads. Bought the NiMh replacements. Then reading up on characteristics (which I should have done before buying), discovered that NiMh do not like constant trickle charge. It apparently ruins them. The instrument used simple trickle charge. Changing that to implement the correct charge profile for NiMh wasn't feasible. So I had wasted a significant amount of money.

    I will still be swapping out the charge circuitry on this as it will be on 24/7 under load with the batteries becoming a UPS of sorts. More fuss to protect the LiPo's and also deal with the voltage change in this case.

    I have a whole collection of Proxxon tools. The Vice above, plus a hand drill, drill jig, drill extension rod (good for hand modding plastic cases or work outside the jig) and circular saw (really good for PCB cutting if you use a diamond blade). So as you can guess, I think their tools are good too. I wouldn't recommend the vice with suction base. It loses it's grip with even the slightest of pressure on the vice.

    Now I fully understand why Westerners boycott shit exported from China. They don't have to follow the same quality standard as their domestic counterparts have to, so a manufacturer can literally dump any illegal shit, as long as they're not sold within Mainland China.
    Not all westerners are exposed to the same quality. Here in the US the "cheap chinese stuff" has much higher quality than the crap I buy in South America (more specifically, Brasil and Argentina) - especially when talking about chargers, extension cords, tools and children's toys. They are actually dangerous but can be bough everywhere. Shameful, really.

    That happens in the UK too, my partner worked for a number of hotels up to 5 star in London and it's quite common to have maintenance reset breakers because people trip them with grills, it's also common to throw kettles away because people 'cook' in them, on one occasion she told me of a visitor who was storing fresh food in the bath with ice from the bar.

    I keep looking back at this. It's a very nice vice indeed! I think it's a much more upgraded/refined version of the one I have.
    I love mine so can only imagine how much more a treat to use yours is. I see yours is about 5 X the price of mine but with these things you get what you pay for....  most of the time!
    That's one of the things I like about the forum, you get a real world review of these things.

    I know some will say "you don't need a more expensive vice" or whatever, but sometimes it's nice just to have these things. Kinda like owning a a Mercedes when a Ford or Vauxhall will do just fine.

    I'm very tempted to invest in 1 and keep mine as a back up and to use the odd time you need 2 vices.

    We'll see....  :)

    They look identical (in design) to the Proxxon, just a different colour. However, I've no idea whether they used cheaper materials.

    Speaking of which, I used my last Proxxon vice (suction cup version) to push close 100x 50pin Centronics IDC connectors to flat cable and when I was finished, the threads were completely sheared off and I had an ex-vice. So they are not made to handle higher pressure.

    Had mine for several years, I went for the a couple of the suction versions as they seemed more flexible on the bench. They are fairly heavy and unless it's off balance are fine for connectors and small pcbs etc. I don't use the suction but if required you could properly clamp them down or use a jig to secure them to the table.

    No idea how strong they are but they have a bit of weight to them and do clamp tight for holding. The jaws have removable silicon grips and are unscrewable steel plates themselves so easy to do a wood conversion. Aldi isn't exactly staffed with rocket scientists so even if you put it through its paces they would likely take it back without issue. The price is right anyway.

    The two Workzone branded small vices (suction and edge mount) from Aldi go on special once a year for about $15 each which is a bit of a bargain.

    After a bit sniffing, I found the literal smoking gun -- a smoking UK to universal socket adapter.
    Those universal adapters are crap + dangerous because of how they're designed. The nickname deathdapter is well deserved.

    The previous one probably suffered from a high current load, maybe someone plugged the kettle in it.
    I was talking to housekeeping last time I was in HK and she said some people bring their own electric grills with them so they can cook in the rooms :palm:

    That happens in the UK too, my partner worked for a number of hotels up to 5 star in London and it's quite common to have maintenance reset breakers because people trip them with grills, it's also common to throw kettles away because people 'cook' in them, on one occasion she told me of a visitor who was storing fresh food in the bath with ice from the bar.

    A bit off topic, but back when I was trundling around the State doing annual routine tests on AM Broadcast transmitting sites, we had to do them "after programme shutdown".
    It got a bit wearying, so the electric kettle was kept busy making coffee as we worked through the night.

    Finally, there were only the antenna tests to do, at the "mast hut", which would take another couple of hours.
    Remembering that there was a power point  at the hut, we took all our coffee making stuff with us.

    There was no real path, (overgrown), but finding our way to the hut in the dark was easy, with the outside light on the Tx building, & the mast lights  to guide us.

    On reaching it, the first thing was,"Let's put the kettle on!".

    Did so, & we were greeted by instant darkness!
    Interior  & exterior lights of both huts, ---- gone!
    Yes, the mast lights were still on, but they just showed us where we were, the Tx hut was invisible.

    I had to find my way back in the pitch dark with the only torch (flashlight) & replace the fuse.(Yes!  A fuse!).

    I banged my knee nicely on one of the "star pickets" they had stuck in the ground to indicate access points for testing the earth mat.

    After missing the Tx hut the first time, I finally got there & had to search around in the engine room for the (poorly marked fuse), but eventually all was well.

    Why the internal/external lights of both huts, as well as the power socket on the wall of the mast hut were on the same (underrated) circuit is beyond me!

    It was, however, a salutary lesson on how high the power draw of a simple domestic appliance can be.

    Australian hotels & motels usually supply an electric kettle, so in those places, the socket is well able to handle a reasonable load.
    This could well lead people from this country to expect the same performance in another country, using a cruddy adaptor.

    I was going to do the same thing to an instrument that had a lot of dead NiCads. Bought the NiMh replacements. Then reading up on characteristics (which I should have done before buying), discovered that NiMh do not like constant trickle charge. It apparently ruins them. The instrument used simple trickle charge. Changing that to implement the correct charge profile for NiMh wasn't feasible. So I had wasted a significant amount of money.

    Looking at Wikipedia, it's probably fine, just you have to use a lower current. It cites a Duracell and Enegizer who suggest C/300 and C/30 as good limits. I used NiMH in my voltage reference, and it is fine so far after a few months of charging.

    Actually got the cells concerned on charge at present. The second cycle is running at present and looks good so far. Hooked up to one of my R/C chargers for cycling so I can see what they are doing.

    As it is a 10 cell pack for the HP I will be making a dedicated peak detection cutoff charger for it based around a suitable TI chip. These switch from rapid to a float charge and should look after the cells.

    With your Vref be aware of the self discharge issues of NiMh unless you are running Enerloop type cells too. I have LiPo's in mine to avoid that issue.

    Well, I got my chain jerked on that one.  It was the new model currently selling for $32-$35.  I requested a refund and it is on its way back.  At the same time I bought that one, I picked up 2 well used with some bits for $45 shipped that work fine with a bit of Break-fee and just scored a very good condition one with bits for $30 that will be here Tuesday.  The 2 best will go in my work tool bag and the other will come in the house and have a fairly easy life.  I have tried T-handles in the past and didn't like them.  How are the Xcelites?

    There are a dozen or so Fluke 6080AN Synthesized Function Generators on Ebay for $125 that look like they were tossed from height into a dumpster.  I found one with the best looking case without any damage to the front panel / connectors, but didn't power on.  I tried talking the seller down to $75 but they said they are worth more than that as scrap metal(~60lb beast). 
    Hopefully it's a power supply fuse/fault and everything else works, if not there's a full user manual and service/calibration manual with schematics an will be a fun project to tear apart.

    I don't know where these Fluke 6080A's are coming from - there certainly have been quite a few over the last couple of years, all at about $125.  I bought one a
    while ago as did two of my friends.   All of them worked with some minor repairs needed.  For instance, on mine, the previous "repairman" had shifted one of
    the ribbon cables to the back panel one column of pins.  That created havoc with the GPIB lines and locked the machine up.  About a year ago, an LM317 regulator
    went in the P/S which took most of the rails down - an easy fix. 

    But they truly are a hidden gem and a real bargain even at the ask price of $125.  In my experience, they are every bit as good as the HP 8642A generators which
    usually go for a whole lot more.

    And yes, they are HEAVY!

    I got myself a nice Fluke 89iv a couple of days ago. It was really clean and tidy with no marks of scratches or anything like that. It was a tiny bit grubby as you'd expect from a 10+ years old meter. It's been well looked after and spent it's life on a clean bench somewhere and whoever owned it before me has looked after it real good. I gave it a quick wipe and it's came up like brand new!
    I forgot to take a photo or 2 to show just how clean this meter is. I'll do that tomorrow and edit them into this post.
    I've also had it on my DMM check thing and it's as near as damn it with my other meters.
    The only thing wrong with it is one of the real feeble black plastic twist screws that hold the battery door closed has lost 1 side of it's shoulders.

    Does anyone know where I could pick one of these up? It's a real shame this tiny thing is broken on it as it is otherwise minted.

    I don't own 1 so i don't know if it would make a decent 1 or not. I would tend to agree with you though just on what I have seen. It's amazing what they can replicate so precisely in all manor of flavours!
    I have thought about getting 1 in the past but I really don't have the room for 1 anywhere.
    I live in Edinburgh so I am sure there will be a 3D print shop up town. I'll see if I can get them out without breaking them and if I can i'll try getting 1 3D printed.

    Thanks for the idea  :-+

    It's been a nice week for me. Got myself an Advantest TQ8346 optical spectrum analyzer. The specs for it are kind of missing because the only manual I found was in japanese,   but the unit itself only lets me input ranges from 850nm to 1700 nm. I also did a brief teardown of the optical unit ans ut looks like that one supports also the visible spectrum (starting somewhere from 400nm,  my guess)

    Also,   completely unrelated to electronics,   I got myself a Tos dividing head. Weird part about that...  I don't have a mill for it...yet But it was so cheap I couldn't pass the offer.

    This is the teardown of the optical s.a.

    Try hitting up http://www.adcmt.com/ (http://www.adcmt.com/) I was chasing an Advantest manual a while ago. Took them a while to get back to me but had a few emails back and forth from them from one of the Managers (in English ;) ) Good Luck

    Trawled up the manual for a TQ8341 and dropped it on my Google Drive if it helps. https://drive.google.com/file/d/1U_xd-2cR4k80CD3eiI7j9jyWZMjCgy8d/view?usp=sharing (https://drive.google.com/file/d/1U_xd-2cR4k80CD3eiI7j9jyWZMjCgy8d/view?usp=sharing)

    Yesterday I was lucky to pick two car loads of trash bags full of discards of RF metrology kind (with their full permission, I work there but not directly with rf hardware).
    So far sorted through one third of it. Mostly empty static bags and print cartriges etc. Good finds are 3x beautiful new 22000uF 63V caps, two tiny 100W DC-DC converters totally new, tiny RF smt relays. Lots of smt chips.

    Other useless, bus amusing is loads of 2.92mm connectors with semirigid cables ends, reels of 0402 passives, too small for hobby, bare dies, etc. No use for me at all, but hours of entertainment of treasure hunt.

    Yeah. Be aware that the snap stud is not connected to the ground wire on these cheap connection points. You'll need to add a jumper wire on the back from the stud to the back of the sockets if you need to use it.

    Hi all, I bought the ZD-8915 and JBC CD-2BE. Yeaahhhhh. The ZD-8915 I ran through some of it's paces and it works, so far, very well! The glass tube is a night mare to take out. Now in search of 1 eurocent coins as we never had those in the Netherlands. A US dime or perhaps some other copper (plated) smaller coins will do the trick as the mid-point stopper and solder catcher. I've now squeezed in from an previous de-soldering equipment (Philips rebranded SEM/FTM technologies). The JBC I did not try yet. Only connected it, played with the super fast heat and sleep mode. And of course updated the software. Very happy so far with these purchases and will definitely try out some other active tips for the JBC from other sources (.... express). Should I post pictures?

    Very very happy with teh JBC CD-2BE. So nice, fast, lot's of power. Only a big smile on my face when soldering. Now I need start using other tips and let's see how long the tips last.

    I purchased the same one about 18mos ago and have not yet replaced a tip. My setup has about 5 tips in common use and I have done a LOT of soldering. If you avoid violent cleaning on the brass brush - they last a long time. I have seen a few people that are really rough with the cleaning which offers no benefit and reduces the life of the tips.

The head bolt inside the hole of the terminal does not interfere with the connection with that sort of terminal.

    On Ebay I purchased some 50 Ohm feed through terminators, but they turn out to miss the 50 resistor inside. Contacted the seller, he refunded me and thanked me for taken the time to verify and send him a photo. Turns out that he is still selling the same terminators  :--

    After that I bought the last 3 50 Ohm terminators from another seller, since I only had 2 terminators, leftovers from the ThinNet (10base2) era.

    I find the price of €20... €30 and up, a piece, just to expensive for what they are. But in this case, a cheap deal turned me into a sheep.  |O

    Photo attached: on the left the good 50 Ohm terminators and on the right that bad pass trough.

    Indeed, I don't remember 50 ohm terminators costing much back in the ThinNet days. I'm shocked at what the ones for test gear cost!

    There do appear to be some cheaper ones out there, though, not to mention the option of DIY (discussed on a thread in the forums).

    And isn't another option to use a BNC T-adapter and put a cheap non-passthrough terminator on one jack?

    The T's with the 50 Ohm terminator non-passthrough is what I've been using. I have a tek2445 with 50 Ohm inputs option, so that solution have been fine for my needs. But I recently bought a DSO that has no 50 Ohm inputs, and using those T's on the inputs of the scope... it gets all cramped with BNC connectors, so the passthrough option would be sleeker.

    I may try to fit 2 // 100 Ohm SMD resistors inside each (useless) passthrough that I get at Ebay, and bring those to the intended purpose.

    Fluke 8845A, for about US$160, from eBay.

    A couple of the ranges don't work. I'm thinking that the relays are bad since I hear a thunk when switching from a working range to the broken range.

    I ran the firmware upgrade procedure (thank's TiN for the FW download). Unfortunately, I wasn't good at following instructions, and thought the "The next step takes up to 12 minutes. Click Ok when it says done" was a "The next step takes 12 minutes. Click OK to start" message. So, once you click OK, it says to power cycle it..... so I power cycled it as it was sending the inguard FW over the optical link, corrupting its flash. I also now know the commands to directly modify the various calibration constants, so that's nice, too.

    Fortunately, the firmware contains the raw data that needs to be loaded to the flash, so I desoldered it, reflashed it, and it worked again. Nicely, I also was able to grab the root passwords for it from the firmware image (different password for the three ports it uses). I _think_ you can also tell it to be an 8846 over the interface and it'll believe you. The 8846 supports USB storage, has a more stable LM399, higher resistance range, lower AC range, capacitance measurement, RTC, and temperature modes.

    For me, the USB storage and low-current ranges would be good to have. If it accepts a "MODEL 8446" command, then I'll start purchasing the USB components.

    I also have found some that may be easier to adapt (or even actually have the resistor inside), but their bulky box may get in the way if you have many probes attached.

    Like I don't have enough leads kicking about the house as it is.

    After specifically buying a parallel and Com ports for my desktop for the hi fi company's streamer they go and make a change on the firmware or firmware updater software so that it needs a USB to serial converter lead to make the update. |O

    No looking for a USB front panel for my desktop as both ports have failed. Or maybe a wall mount..
    I'm getting far too old and ineffective at contortion to crawl under the table the desktop is on to try and mate connectors.

    I went to look at a couple datrons. 1 x 1062 and 1 x 1072 as described: turn on, pass all self tests, displays good. That turned into 1 x 1072 and 5 x 1062 when I actually got there  :palm:. They all had error 5 or error 6, one had Error OL. One had a bad display, 1 had a bad keyboard. I ended up buying 2 x 1062 with error 5/6 and 1 x 1072 with Error 5 and a busted low input jack. All good displays and keyboards. The seller threw in one 1062 that started smoking while I was trying to check them(A tantalum happened to burn up). I ended up paying about $200 and the whole 2 hour drive home I kept thinking about how I probably just threw $200 in a fire. 3 1/2 hours later the 3 I paid for are all working and pass self tests. I also have a spare 1061/2 display to boot. Really lucky he threw in the spare, without it I would have needed to spend more money to get them going. All the batteries were 3.7V. Now I should just need to buy caps to replace the electrolytics and see how the calibrations are.

    I believe these were made through the 80's. 1050's were pre 80's and 12xx were 90's. I'm not an expert though so that's just an estimate. I believe datron instruments went down right around 2000.

    Quick edit: The 1071/2 may have been around longer. My ROMs are from 94, or they just continued updates for a while.

    I won these puppies on Yahoo Japan, approx USD30 each shipped so I basically stole them. Brand new they are $450+, which is far too much for a lowly hobbyist like me but deals can be had on the used market for a niche item like these. I've been on the hunt for these for nearly 5 months now, wooohooooo.  ^-^

    There's a sticker dating it back to 1993 so it's nearly as old as I am but as far as I can tell from a few test crimps with the proper PIDG terminals, they still work wonderfully. It came with the original manual and it still has the locator tabs which makes it so much easier to position the terminals. As much as I love my Pressmaster crimper there's no beating the original tooling.   :-+

    Picked up a decent used HP Slimline to replace my dead bench PC. I'll be doing a few minor upgrades to it.

    Two things you may want to add in there: a better processor and a graphics card. Just buy both used and you will get a good performer as a bench-side computer.

    I've got an SSD drive and AMD ATI Radeon HD 7570 1GB video card for it. I will be upgrading to a quad core i5 as well. That should be plenty for anything I'll be using it for.

    Got  for 1EUR ^-^ this baby Extron GLI-350xi (see attached pictures for a baby-teardown  ;D ), hopefully will make  a 10MHz/1MHz distribution box for the GPSDO and Rubidium sources.

    I'm wondering if it has enough sockets or should I bid on one of these  >:D:
    eBay auction: #333106244397
    or even this

    They seem to be pretty modular, so if another forum member ask for a card I should be able to provide  :-DD.

    How do you distinguish them, I've always been curious, or is a datasheet thing ? In the case of my baby it's probably because the standard for analogue video is 75ohm but the device is made to communicate with a similar device, so they used the best impedance for the distance.

    75Ohm BNC have less (or none at all) dielectric around the center pin than 50 Ohm BNC connectors.
    The video stuff is supposed 75 Ohm, so the 50 Ohm output connectors are in the wrong place.

    Historically, the difference at analog video bandwidths didn't really matter.
    Many Studio patch panels were wired with 50 ohm  connectors, as they are less fragile than true 75 ohm connectors.
    When they started piping digital video signals around the Studios, the impedance became more important.

    Getting tired of using a manual solder sucker and trying to cleanly remove through hole parts during repairs, so I went to a hamfest today and scored a factory refurb Hakko 808 with limited warranty (the seller is trustworthy - I buy soldering equipt from him regularly).

    Nice desoldering gun. I love mine (different model Hakko) and use it all the time.


    Bought a scrap HP 5340A for parts I need to get mine running.

    I need the older transformer with the 155V winding for the nixies, and this also comes with the otherwise unobtanium smaller Option 001 transformer to power the optional OCXO, along with a bunch of other bits to replace missing parts in my unit.

    I'll spin up my own Opt 001 power supply PCB and the OCXO is available online as it was used in multiple HP stuffs over the years.

    So, I bought a bk9104 a year or so ago for some testing of a led driver board that had to operate at about 60V and several amps input.

    Now I need a new supply to deal with 12V or higher and at least 12A at the input. So, in steps a bk9103 (320W and up to 42V or 20A).

    Two packs of 10m LAN cables. Looking for some 10GbE LAN cables that are honestly rated, only to find Amazon cables are all fake "CAT 7" with no bundle-level shielding.
    This is also not bundle-level shielded, but at least this is honestly rated at CAT 6A, not CAT 7.

    Weird, but sometimes the Japanese only sell some of their products domestically, and if you want it outside Japan, you have to buy it from shipping agents and pay a hefty international postage.

    Its motors are not good at all. When XY axes are moving at the same time, linear velocity lowers, hence effective laser power increases.

    They are a bit of a mixed bag. I went a bit more upmarket for a 40W which added a few nicer features before a few more mods. to improve it some more. Take any review online with a big bag of salt as always if their is sales links attached. Being able to get the correct drop in replacement tube is a major thing to consider.

    A good option for lower power marking and very limited cutting is add a 0.5W-5W Laser to a 3D printer as a clip/magnetic add on. The 0.5W one I got a while back marks softwoods and cuts heavy paper and I also burnt the label off an IC package as a test.

    drescherjm they're not bad power supplies... just be very careful of the preset buttons!

    if you're not using presets, go through ASAP and set them all to 0V.

    I was working with someone the other month and they had a prototype rigged up with a bunch of these supplies... they reached down to turn the outputs off on the different supplies, and managed to hit the preset button next to it instead. The preset was set to full 30V and full 5A CC. The circuit it was wired to was designed for a maximum of about 6V.... not a happy accident.

    Word of advice: don't buy it. It has ridiculously loud coil whine. I ended up stuffing the box with layers of foam to dampen it. The coils (plural) are closed, so I can't fill them with silicone gels.

    It may be beneficial to post the manufacturer and model so folks know what to avoid if they're in the market for one.

    I thought I remembered the same, so I made sure to double check. The dual channel model turns off the outputs when another channel is selected. All similar supplies I've seen in reviews turn of their outputs when another channel is selected too.

    Thanks a lot. I just got the supply and the defaults were 30V for two of the presets. I definitely would not want that.
    Does your supply turn the output off when switching the channel?

    Good point! Thankfully it does so I don't have to worry as much.

    Bought a Cordless Bosch hot glue gun which arrived yesterday, this is a great unit and works so much better than my $7 ebay pos! it heats up 15 seconds instead of 5 minutes and charges from micro usb which is super handy!

    Nice, didn't know these were that much faster.
    Now I will wait till they equip it with the extra long tube for ultra precise dosing.

    Yes that is a big salespoint.
    But if I understand correctly it only heats up when you press the button, so it is not directly ready but you have 15 seconds?

    No it has a power button and it heats up when you turn that on. The temp indicator flashes while it's heating and goes solid on when temp has been reached.

    I don't know! I never seen anything like that on a modern high density multi-layer board.  They look like the old hand drawn traces style.

    I did a T shape engraving on a Toshiba flash chip with my new Cubiio toy laser.
    The left is a failed attempt with bad focus, and the right is a perfect T with crispy but slightly burned edge.

    The built-in rasterizer was way worse and it will guarantee to mess up some corners.
    The T shape shown here is based on my own rasterizer using only G01 X and G01 Y code.
    The firmware implementation of G02/G03/G01 X Y motion is flawed and is guaranteed not to work precisely with small feature sizes.

    That thing is a Chinese-made FPGA with 1024 LE in a QFN48 package - seem like a competitor to Lattice iCE40 series, and it costs half as much.

    BUT. THE. DEVELOPMENT. TOOLS. The company made that chip is not providing the tools to anyone except their authorized resellers, and the specific reseller I bought it from, LCSC, does not admit them being an authorized reseller. Now the only thing I can do with those chips is literally eat them.

    If an authorized reseller will actually pick up the phone for a quantity of less than 10ku... (maybe or maybe not, I didn't check).

    Seriously, technix, what were you thinking, man?!?  :o Embarking in an adventure like that without taking a look at how crappy or good their tools are is a long shot in the dark. Even if you are able to get the tools, who knows if they are any bad or good?

    Seriously, technix, what were you thinking, man?!?  :o Embarking in an adventure like that without taking a look at how crappy or good their tools are is a long shot in the dark. Even if you are able to get the tools, who knows if they are any bad or good?
    Trump scare.

    I am Chinese, and all of Intel, Xilinx, Microchip and Lattice are American companies. I need an escape route for my FPGA based projects if Trump decides to put an embargo on China our of the blue for whatever reason he heard from cable TV that morning. He is volatile yet my entire line of business can be snubbed out by him sneezing the wrong way.

    I was already getting annoyed at Xilinx and their export control system, and he is touting further trade war with China.

    I bought one of my biggest disappointment: AG1KLPQ48.

    That thing is a Chinese-made FPGA with 1024 LE in a QFN48 package - seem like a competitor to Lattice iCE40 series, and it costs half as much.

    BUT. THE. DEVELOPMENT. TOOLS. The company made that chip is not providing the tools to anyone except their authorized resellers, and the specific reseller I bought it from, LCSC, does not admit them being an authorized reseller. Now the only thing I can do with those chips is literally eat them.

    Ugh.

    Well, spend another 1.55$ and buy one from an authorised reseller, problem solved  ;D
    They don’t have a list of authorized seller available almost anywhere. There is no phone I can call or Email address I can write to.

    Or baybe I should pay them another visit and ask them for a list of resellers, face to face.

    Recently I found the FPGA chips from Anlogic, also available at lcsc.com. You can even buy test boards here (https://www.seeedstudio.com/Sipeed-TANG-PriMER-FPGA-Development-Board-p-2881.html), bought today. Nice about the bigger ones, but still less than $10: they have 8 Mbyte integrated SDRAM, and 130 kB block RAM. And I could download and install the Anlogic TD IDE from the seeedstudio webpage in a Windows VM. The installation dialogs were in Chinese, but looks like the program itself is in English.

    These are good meters, I bought the 1587 when they were just released and it is still going strong, and always passed calibration better than the stated specs.
    I've still got it and use it all the time (the megger function mostly gets used for zapping friends these days though  >:D ).

    The 1577 is just the basic version compared to 1587 and the 1587FC which would have been "nice to haves", but I really only need the 500V/1000V insulation test, for everything else I already own a 289 and 87V (among others). So I jumped at it. It certainly offers more than my Megger did and there's no handle winding required.

    Nice buy. Did it come with the remote probe (TP165x) that makes it really handy for doing tests.

    I bought a 1577 a few years back for just over AU$200, then saw a 1587 come up at a decent price, so I bought that and listed my 1577 for sale. The 1577 sold on eBay auction for a little more than I paid for the 1587. A little bit later I saw a near new 1587fc on eBay, put my bids in and got that for a bargain. Put my 1587 up for auction and it sold for more than the 1587fc cost me.

    I’m finding the bargains to be fewer and further between these days, but they’re still out there.

    Can you create a new thread somewhere on this forum for it? I'm struggling myself using the Gowin_YunYuan IDE. Would be really nice, if there would be a good "getting started" documentation for these Chinese FPGAs, like you get from Altera (now Intel) or Xilinx. But I know that it is time consuming to write good documentation. Maybe this is the reason these FPGAs are so cheap :)

    Yeah, it's really good to drive so far. I've always tinkered and built my cars. Buy a second hand import (when I lived in Australia) and rebuild it from the ground up.
    It's strange in a way, having a car that is already brand new... There's nothing to do! Just drive it. :D Being a hybrid, I wouldn't even know where to start beyond an exhaust system (Which wouldn't even be used half the time...)
    Although, this one won't be hauling much building materials... My better half would kill me too. :D

    This was very much used.  It was my retired company van.  Paid almost half of Kelly Blue Book value for it.  It is not a daily driver so even though it has a V6 in it, there are times we only gas it once a month, only about 12,000 miles in 2 years.  That includes evacuating from Florida to Kentucky for a hurricane and a trip to texas.  Mrs GreyWoolfe also has a little side gig doing house cleaning so it is great for carrying everything for that.  We both really like the 4 door Hyundai but the van just opens up so many possibilities.

    We also bought the first retired company van and ended up giving it to my mother in law.  With the help of her son in law and daughter, who she lived with, and prudent visits to local junk yards, she was able to convert it back to a passenger van.  Goes to show not all vans are driven by soccer moms!!

I got a great deal but it looks like it has seen plenty of hours. One nice feature is that you can set the temperature before you actually turn on the heat. Has a fairly chunky aluminum plate as well. And a cover to retain some heat for smaller reflow tasks.

    Two external hard drives for backup. One 8TB to serve as an off-site backup for my Mac Pro (which already has an 8TB internal backup drive), and a new 2TB portable for my MacBook Air was filling up (so its existing backup disk can be an off-site backup, too).

    (Mac users: Did you know that Time Machine supports multiple backup destinations? Also, you can encrypt a backup after the fact by removing it from Time Machine -- it won't delete anything -- and then adding it back with encryption selected. It'll add the existing backups and encrypt them retroactively.)

    Once they get fiber in my neighborhood, and thus have really high upload speeds, I may consider an online backup, too.

    Thanks. It’s close enough to my new town to be convenient, but far enough (6 miles) to get away from the noise, crime, etc. The yard is no longer pristine though. We had to install new drainage.

    As long as it's not too outrageously hilly. I'm something like 1.5k from work as I walk it, but given that I have to drop a few stories, climb back a few, then drop to sea level it's not a stroll.

    Normally not a problem, although I do have my first proper HP boat anchor waiting for me at the office when I get back to Sydney. I suspect I'll have to get a coworker with a car to help me get it home at some point.

    Bought these 2 off of evilBay.  I am out of outlets on my workbench and the PDU will let me connect my network hardware directly to my UPS and will sit under my switch for neatness.  The weedwacker line for my Craftsman weedwacker as I do not want to go through the hassle to find what other shaft/head will fit it and I like the .110 inch line.  Regardless of what people think of Sears, having a small independent (I think) Sears store 5 minutes from the house was very convenient.  It was sad to see the store empty.

    Bought from Ebay a Hantek T3100 (2KV 100MHz) oscilloscope probe to measure some things that may go over voltage for my regular 300Vrms probes, like the output of some CCFL power supplys, with working frequency in the KHz range.

    Image 1: probe measuring a sinusoidal with aprox. 730Vpp, 260Vrms, 35KHz
    (EDIT) Image 3: hardcopy from scope

    With the probe calibrated with the traditional 1KHz signal from scope, as the frequency measured rises, an undershoot slowly increases.  Attached a screen capture (image 2) with the above yellow trace from a TEK P2220 and the lower blue one, from the Hantek T3100, measuring a 4Vpp 1MHz square wave. For what I intend to use it, and for the price (€17), the T3100 is suitable. I'm just not a fan of the "unclipping" clip, but otherwise the probe seems well built.

    I know the Testec are somewhat appreciated in the community, but they are more expensive and to spend more on a reasonable better probe, I had to put more thought on that. But if someone as any suggestion I'm always glad to ear it.

    It is a bunch of used computer parts today: a Colorful C.P45K motherboard, a Gigabyte GA-Z97P-D3 motherboard, a 500W ATX power supply unit, and a NVMe riser card.

    The Colorful motherboard and the 500W PSU completes the machine for my mom, with a bunch of spare parts from my junk bin: a Core 2 Quad processor, four sticks of 2GB DDR2-800 memory, a spare SSD and a GTX 1060 graphics card.

    The Gigabyte motherboard and the NVMe riser is an at-grade replacement for the current motherboard in my Hackintosh, allowing my to put my (currently spare) Samsung 960 Pro 512GB NVMe SSD into it.

    DMM on PCIe card?

    DMM on PXIe card. PXIe is PCIe*1 in Eurocard form factor with Compact PCIe connectors designed for PC-based instruments.
    Unlike PCIe cards which terminate on bottom side, they terminate on back side. See attached pictures for how the chassis connector looks like.
    That has to cost an arm and a leg... I wonder if such cards has regular PCIe versions? If so a PC-based DSO That also has a good graphics card would be interesting (high sample rate near real time spectrum analyzing using the GPU for FFT?)

    The card has an MSRP of over $3700, but there's no way I paid anywhere near that, despite being brand new. I paid $1400 for it, which is actually considerably cheaper than a standalone 7.5 digit DMM. The performance of this card is better than 34470A, on par with DMM7510, with digitizer option (the combo would be in north of $4000).

    For what you are asking, a PXI system is the answer.
    A PXI system can have an embedded controller, which is basically a computer with PCIe brought to the backplane (or an interface card that plugs into another computer through an MXI cable or Thunderbolt 3 cable), a bunch of test & measurement cards, and a switching backplane.

    NI used to make PCI/PCIe-based DAQ cards, but those were phased out over the years for whatever reasons.

    For your FFT question, yes, there are GPGPU or FPGA accelerators for PXI as well, just cost over $10k. Anything PXI will be more expensive than their standalone counterparts, mostly due to the added value from automation and equipment virtualization.

    Remember, for high profit businesses, cost isn't essentially the dictating factor of price. Created value is.

    I have a video tour of my PXI dream box coming soon, I'll post a video once it's uploaded.
    What I am wondering is that whether I can plug a non-embedded-controller PXI unit to an existing gaming PC or graphics workstation that already has a good GPU in it.

    Also I wonder if there is PXI-to-PCIe adapter cards, that takes one or two PCIe slots in an regular PC to create one PXIe slot.

    1. Yes. NI has an PXIe-8301 card that allows bridging between Thunderbolt 3 and PXIe, thus allowing PXI/PXIe cards to plugged into a PXI chassis, then connected to a computer at PCIe level.
    2. A PXIe slot can accommodate PCIe cards with an adapter, not the other way around. PXI is taller than PCI, thus a PXI card won't fit in a standard ATX chassis. A PCI card is longer than a PXI one, so with an adapter, a PCI card inserted in a PXI chassis will protrude by about an inch.
    I wonder if there are PXIe to PCIe adapters that accepts a dual slot PCIe card. If so it might be cheaper to buy that plus a gaming graphics card like RTX 2070 or RX 580 than that GPGPU module, while achieving a similar if not better GPGPU performance.

    How much would a non-embedded-controller PXIe chassis plus that Thunderbolt 3 card cost? If it is cheaper than an embedded controller one it can be cheaper to add PXIe to an existing lab PC.

    A low power PXIe slot can consume and dissipate no more than 38W, and a normal one is not much higher than that. Also, PXI is 100% backplane powered, so there's no 6P/8P connectors provided by the chassis, not the cable management space for you to run the cable. Also, PXI is passively cooled and it expects no fans on its cards in order not to mess with air flow of adjacent cards.

    I bought my box for $450 as "for parts not working". It turned to be a minor dust accumulation problem compounded by a dead fan. When the problems were fixed, it went back to life.

    A brand new PXIe-8301 would cost $999 from NI, which seems to be high, but is probably the cheapest card you can buy in the PXI world. Getting into the PXI land would need a lot of commitment.

    Let's just say it this way. I traded my 6GHz scope with all options for a PXI box made with almost 100% used junk. Only the NI DMM is new. And I ended up spending a few k$ in between.
    Sheeeeeesh.

    I wonder if there is a USB-based alternative for this? Microsoft has published the USB HID Sensors v2 specification for sending readings back and configuring the modes, but AFAIK few people is using it.

    USB based everything is generally cheaper than PCIe too.

    Hey you know the rules - don't plug it in - take it apa-r-r-r-t! And post some piccies  :popcorn:

    Seriously though it would be interesting to see what's inside as they are pretty small compared to a conventional DMM - the power supply is external but it will still need an internal isolated DC - DC convertor.

    On which point the documentation keeps referring to the 'Isolated Digitizer' which seems odd as the DVM has to be isolated surely - the spec says 1000V max voltage from Hi terminal to ground? Is it simply trying to distinguish itself from typical DAQ/digitizers which aren't isolated perhaps?

    The documentation seems very poor, or at least I couldn't find a proper reference manual, only the datasheet and a getting started user manual.

    I don't think it was considered when the first model 7150 was designed but was asked for by customers so added in and called "7150 PLUS". Because of the original design, the only way to add it was mount the switch off the front panel.

    It works really well and the SW is somewhat basic but very responsive.

    There's something strangely the wrong way around when you're explaining PDF in a paper book. :D

    Only if you believe PDF and e-texts in general are ergonomically and philosophically superior to physical texts. Imo it's like med-school autopsies - the more nice clean paper texts and the less handling of stinky, contageous putrescent PDF binary flesh, the better. This is partly for a project to write a PDF structure dissector.  Because amazingly, there doesn't seem to be a decent freeware one around.

    For all the PDF-fans, here's a nice read:

    Picked up this little beauty.  It is a Seth Thomas WWII vintage U.S. Maritime Commission wall clock.  It is a bit rough around the edges but it does work and keep time.  I am visiting the local jeweler who restores old clocks to get some advice on a simple clean up.  I don't want nor can afford a full restoration.  I just want to clean it up a little.  From what little I have looked, it has a waterproof bakelite case so it could have served on land or sea.

    EDIT: I took a better picture, didn't realize how dirty the glass was so I cleaned it up a bit.

    As I'm not sure how experienced you are with mechanical clocks: don't grease the mechanism. Most clocks are designed to run dry, as grease or oil only attracts dust and accelerates wear.

    That is why I am bringing it to the jeweler.  I don't want to damage the clock in any way.  Since the clock is working fine, I am not even worried about the mechanicals.  I just want to clean it up a bit safely.

    A fairly decent looking 1082 with error 6. I'm betting it's the 2/4 wire switch issue but willing to fix it either way. Probably overpaid a bit at $325 but now I'll have 1062, 1072, 1082. Worth it just for the stack.

    I just made an semi-impulsive buy here: a Myir Z-turn board with Zynq 7020 (http://www.myirtech.com/list.asp?id=502) plus a breakout board. It would be curious to see some homebrew hardware share a chip with a proper ARM core running full blown Ubuntu Linux.

    I also intend to mod the board once I received it, hopefully with 512Mbit NOR Flash.

    My 1082 came in today. Accuracy is better than the display for sure. That number is accurate.

    Edit: It's all warmed up now, mostly sits at 0.00000 to -0.00004 so this is actually an outlier.

    One more edit, I bought 16 LM309K's. Mostly gold but 2 steel as well. At $4 a piece I figured why not.

    I'd suggest that you contact Fluke to see if they are willing to provide any information. Guess that trying the phone number in the sticker is out of the question by now.  ::)

    Seems that your photos could be a rarity to be found on the web, so... can we expect any "take it apart" in the mean time.
    If any intervention was done over the years, some caps are gone by now. But if you intend to restore it, please take some photos before doing anything, just for history record purpose.

    Just a guess but it does have 'Counter Demo Aid' on the bottom of the Fascia. I would think it is just that made to demonstrate and sell other gear. Occasionally Badged gear turns up as an unknown and some of that was used for internal production and testing.

    BTW, while I was trying to open it, I discovered it also has a flat+phillips screw driver set in it.

    I'll take it back. It's refillable, with a 2.75" metal refill.

    The brand is shown as Hiltand. However, I purchased one and the unit I received appears to be a genuine Kunkin. The unit performs well, the battery capacity function is especially nice and allows setting a low voltage limit, CC and CV work well. CR mode has some strange behavior, I need to test more to see what is going on.

    Boy could I have used this Jul, 2014.  I built a L-C meter from scratch but couldn't calibrate it any better than about 5-10% for lack of a standard.
    How do you know how accurate it is?  What do you have to compare it with?

    How do you know how accurate it is?  What do you have to compare it with?

    I have a HM8018. Some measurements, with the fine-tune knob at 40 pF, measured with my shielded Kelvin probes and 100 Hz measurement frequency:

    - 0 pF (plus the fine tune knob and the cable etc.) : 48 pF
    - 100 pF: 150 pF
    - 900 pF: 951 pF
    - 12.3 nF: 12.36 nF
    - 765.4 nF: 765.5 nF
    - 1.1 uF: 1.100 uF

    Looks like it is dead on. I guess the trick is to use high quality capacitors, which doesn't need to be very accurate, but with very good long term stability, and then trim each capacitor with parallel variable capacitors. You can trim each of the bigger capacitors, as shown in the schematic in the manual (http://exodus.poly.edu/~kurt/manuals/manuals/HP%20Agilent/HP%204440B%20Ops%20and%20Service.pdf) linked in the article from beanflying. I didn't trim it so far, but maybe the seller did.

    I got an RV-622A which I can't find any actual data on. Initially I was disappointed with the accuracy because dividing my 7.090462V reference by half resulted in more than half. Then I remembered this DMM is only 10Mohm in 30V range, the Datrons are the Gohm DMM I have for up to 20V. Any ratio that allows me to stay in <= 3V range is just about right on. For this picture I set it to Ratio with the value of the reference(just measured) as the reference voltage. Pretty much perfect but I already feel like I should have just bought a 7 decade kelvin-varley divider. Maybe later when a 720A isn't so expensive especially now that I have a perfectly good divider.

    Boy could I have used this Jul, 2014.  I built a L-C meter from scratch but couldn't calibrate it any better than about 5-10% for lack of a standard.
    How do you know how accurate it is?  What do you have to compare it with?

    I have a HM8018. Some measurements, with the fine-tune knob at 40 pF, measured with my shielded Kelvin probes and 100 Hz measurement frequency:

    - 0 pF (plus the fine tune knob and the cable etc.) : 48 pF
    - 100 pF: 150 pF
    - 900 pF: 951 pF
    - 12.3 nF: 12.36 nF
    - 765.4 nF: 765.5 nF
    - 1.1 uF: 1.100 uF

    Looks like it is dead on. I guess the trick is to use high quality capacitors, which doesn't need to be very accurate, but with very good long term stability, and then trim each capacitor with parallel variable capacitors. You can trim each of the bigger capacitors, as shown in the schematic in the manual (http://exodus.poly.edu/~kurt/manuals/manuals/HP%20Agilent/HP%204440B%20Ops%20and%20Service.pdf) linked in the article from beanflying. I didn't trim it so far, but maybe the seller did.

    I have done some more testing against my both of my new LCR Tweezers and 34461A and it stacks up well. Part of the problem comes up you would need a calibrated Capacitance meter a lot better to even prove it's spec of 0.25% was good or bad and at best my gear only matches with and agrees with it's spec. The Yokogawa Caps seem to hold up really well over time is the nuts and bolts of it.

    Yes the cables just magically disappear to the right, never to return. The station is a pleasure to use and the tweezer iron makes SMD work so much easier than before. It was expensive, but as the iron is the second most used device (after the multimeter) I think it's a good investment.
    Also, the cables to the two irons are a really soft, flexible silicon, the i-Con Nano had a more plastic cable that tended to get in the way.

    Thanks to Beanflying's review, and thanks to my fault selling my Smart Tweezers ST-5S, today I bought an LCR Research Pro 1 Plus.

    Yes, I do have a better one, I designed a few based on AWG+DSO, VNA S11+tuner, VNA S12 and single slope, but none of them is portable, and both run on IVI.NET with a bunch of measurement cards required. Those are designed for measuring extreme cases (sub-10nH), but not for casual 100uH-range measurements.

    So, I think it's time for a small, grab-n-go LCR meter for building transformers.
    Good on ya BS.  :-+
    Despite the price of these teeny wheeny smart tweezers I dunno why others don't switch onto them too.  :-//

    Weeks will go by before DMM usage exceeds these tweezers here.

    It's an interesting device.  A 2-quadrant power supply that can sink up to 3A of current on both channels.  It does this automatically if the voltage on the input is higher than the set output (up to the set current limit).  It has a dedicated CR mode as well.  Additionally, it has an ominous red glow when viewed from the side.  Apparently one of the engineers at R&S is Sith lord, manipulating the designs from the inside.  >:D

    Nice find.  Your right it does look very similar after checking out the NGMO2 datasheet.  On the NGL the limits are a tad higher, and the resolution and accuracy is better.  But the NGMO2 blows it out of the water on analysis and sampling rates: 10us vs 100ms and there is no kind of graphing at all atm. 

    There are no set wave forms, but there is an arbitrary builder with up to 4k points, but 100ms between them I believe.  As far as logging goes though, the NGL max limit on log size is just the size of the usb drive you plug into it.  It also currently has a little under 1GB of free memory, which you have available for logs as well.  I'm hoping they will use some of the space for new things as the firmware matures.

    How does it compare to the Hakko FA-400?
    don't know, I don't have the hakko ! I found it more noisy than I thought it would be, but it's completely acceptable.
    it absorbs smoke, but you have to be not too far, 20cm I would say, or it absorbs very less.

    I replaced the stock fan with a low noise one (model no: 4800N from Papst) and that quietened it down a lot.

    I am unashamedly a Ryobi fanboy.  I have a circular saw, a table saw and the 1 Plus Hammer drill and right angle drill and a bunch of attachments.  At home depot yesterday, we saw a promotion that was 2 3AH HP batteries, charger and case for $99 and pick a select tool for free.  I grabbed the 3 speed impact driver to go with it as I have wanted one.  On top of that I got to pick my Father's Day gift.   A special purchase Ryobi 1 Plus rotary tool.  Has a motor base, flexible cable and head and uses the 1 Plus batteries.  I love Mrs GreyWoolfe and I love living Green!!! :-DD

    these square black things are better than nothing, I think.. they seem to work, in that they appear to suck in smoke and push out smoke free "air" out the back -  but I have no idea if there's anything in the solder fumes that you can't see, but is still a problem. Of course if there was, you wouldn't know what they were doing to that....

    The issue with using these is you need it right up where you're soldering, and in my experience with ones like this you pretty much need them leaning *over* the workpiece... I have seen a variant of these on an articulated arm, which would be a huge advantage if you were wanting the best option to go for. because it'd be much easier to pull in to solder and push away to inspect, and not be taking up actual desk space right at the point where you're working.

    Just understand that there's no magic - air sucking devices pull air from all around, so you don't get that much reach from any air inlet where all smoke gets pulled away.  All solder fume solutions require you having something at least 4 inches from where you're soldering (I have an under desk metcal thing with two hoses that's like a special purpose stationary vacuum cleaner (one hose inlet plugged, one hose in use) and even that needs the hose 4 inches from the workpiece.

    Years ago, when our workplace was bought out and the assets plundered/stripped, I found a DEC KDJ11 CPU board (PDP-11/83) in the trash.  Someone had already ripped out the processor hybrid, more than likely to reclaim the gold.

    I was thinking about putting it in a shadowbox for display this week when I pondered, "wonder if I can find a CPU chip online for less than ridiculous money..."  The boards themselves sell for thousands of dollars today, but the processor itself can be had for surprisingly little.  I made a lowball offer on the cheapest one I could find and it was accepted.

    So here is my frankenCPU board, all ready to put on display.  I'll probably never own a working PDP-11 (unless you count the SIMH emulator and blinkenlight display), but this is close enough for me.

    There's a lot of stuff on the Bay of Evil which is priced at ridiculous levels....  I suppose that since these haven't been made for 30 years or more, some vendors think they can charge an arbitrary amount for one.  In all fairness, the board has a large amount of unobtainium on it so if you really want a working one, you'll have to allow for that.

    The prices do decline, though, when people stop buying them; they seem lower now than they were the last time I looked - some as little as a couple of hundred $.   :-DD

    An old HP 1630D logic analyzer.

    Recently one of my lovable nearly-grown-up kittens discovered that the pod flying leads of my old 1630G were fun to cut with his very sharp teeth. I caught him after he'd neatly severed only two wires, but damn... Those wires are special. Fine, very flexible, with brightly colored teflon insulation. I repaired them, but this reminded me I have no spares for that machine, other than a small stock of ECL chips.

    Ventured into ebay meaning to buy some spare pod-lead sets, but instead found a whole 1630D. Looking good, working. Got it for $15. But the shipping, arrgh!  Anyway, it's here now and works. It's amazingly pristine, for something so old. Very light dusting inside.  All metal inside and out still looks new.

    Now where am I going to keep it?

Also redid yesterdays Tek logo with a slightly heavier engrave which sorted out the missing fine details.

    3mm Blades. 2mm would be harder to shove the light up and more fragile and 4.5 unless doing much larger panels would be OTT so I think it is about the best compromise.

    Quick update on the GS110EMX switch. Its latest firmware doesn't work out of the box, and I had to downgrade to the previous firmware. And as usual, Amazon provided zero help other than return it and STFU.

    I'm now really impressed by NetGear and its remarkable marketing team. It seems a good marketing team can drag a crippled engineering team out of death.
    Interesting; I have a mixed bag of experiences with Netgear. Circa 2007 I had a printer server (USB-Ethernet adapter) that was a POS, but at more or less at the same time, their Wi-Fi router replaced a terrible WRT54G from Linksys that was plagued by constant disconnections and instability.

    At work I heavily used both Netgear and Dlink - the latter had an edge over the former.

    Currently I have their four bay NAS that works very well for me, but my dad's failed quite early.

    I didn't. :( As I said, I had stuff sent to a friend's house in USA and I took it back with me when I went to visit.

    If you have a friend going to USA soon, that's probably the very best way. Otherwise, a mail forwarding service like hugo suggested. Definitely not worth the cost and effort for just one item (just go with actual 3M from a local distributor), but for a larger amount would make sense.

    Just picked up a HP 3476A 4-channel logging multimeter today at my usual Akihabara junk shop.

    It's supposed to print the measured values to a receipt docket type paper roll, but the printer mechanism is missing, so unless I find a printer mech relatively cheaply, this one will be stripped down for parts in short order...

    It shouldn't be too difficult to decode the data being sent to the printer, why don't you build a small circuit to feed the data back to a PC or directly to a USB stick?

    Yeah, I had that thought too, it would be a shame to strip this unit down if it is otherwise working. 4 simultaneous channels of datalogging could prove somewhat useful.
    A USB port for a USB memory stick an arduino and an oled screen could make for a cool little addon module to sit where the printer used to be.

    I'll probably end up finding space to store this thing and add it to my ever growing list of projects... :D

    A Peaktech 6181 (https://www.peaktech.de/productdetail/kategorie/acdc-stabilisierte-labornetzgeraete/produkt/peaktech-6181.html) lab power supply. I was looking for a multi-channel lab PSU for several years now, and only now got the budget free to buy one which is actually better than my DIY one (which is like 25 years old by now...). The Peaktech triggered all the boxes: 3 channels, all programmable, can deliver up to 6 amps for each of the two main channels, its programmable (and Ethernet is standard), showing both set values and current values. And its not as big as the DP832 (desk space is at premium for me).

    So far I like it. Its rather quiet, the fans (one at each side of the big heat sink) only turn on with load. Once you pull 6 amps into 0.1 ohm they get loud though. Unfortunately these are 24V fans, so it won't be easy to replace them.
    Noise and ripple at the output also look fine. I measured about 2mV p-p, and 5 in CC mode. There is also no overshoot. When turning it on, there is no voltage on the outputs (though I did forget to check the 3rd channel).
    The output capacitors are 100µF, which means it takes several tens of milliseconds to ramp down the voltage when going into CC mode (for low current such as an LED - if you pull 1 Amp its much faster). Interesting: from the output voltage ramp down I calculated about 240µF capacitance, so maybe something is hiding somewhere...

    I have two UI nitpicks: the buttons for the 3rd channel are on the right, but the outputs are on the left side. That's confusing, and they are also not color-coded as the main channels are. And the 'Mode' button sitting so prominently between the main channel controls does not change the output mode (serial, parallel or tracking) as I would have expected, but only the display mode (showing all three channels or only 1+2). Would have been much better the other way round...

    I was able to connect with EEZStudio, but there is not documentation about the available SCPI commands :(

    Build quality looks good, most of the space is taken by the two(!) transformers and the heat sink. I did not dare to take out the main board, as its firmly attached to the heat sink (via all the transistors).

    You know that Peaktech is just a re-badger? The device is actually an Owon ODP3063, so the SCPI commands should be identical if you can find a programming manual for that.

    Hi Terra-Op , I have a couple of these units - they are a sweet little unit - the printer is a bit of a headache - as all electromechanicals are I suppose, the manual on Keysights website is mostly unreadable - I have an original which I have scanned + photographed - if you need a copy PM me, it is a huge file 200M or so I recall.
    If I recall the printer unit is not a lot different from some of HP others thermal printers eg in HP thermal printers for 41CV calculators eg HP 82162A - I am not sure if identical but pretty close.

    The '175 has been the mainstay at every place I've worked at for the last 20 years - I just wanted one of my own. The 1242 was one of the last from the on-line Jaycar bargain bin - got it for substantially less $ than the Fluke. Was surprised by the large test/calibration report that the 1242 came with. I like this Keysight a lot better than my old(ish) Agilent U1241A.

    Next up is either a Keysight 34450A or a Fluke 8808A 5.5 digit bench DMM - am giving myself until tomorrow evening to make up my mind. I have an ancient Fluke 8502A (6.5 digits in high res mode) but it needs an little renovation now and something decent to calibrate it against.

    Well I guess it's settled. I'll refrain from parting this one out and see what I can do about making it work in some way.
    I do like the idea of that addon module with usb etc... It might be a little while before I look at it, but I'll add it to the todo list. :)

    If we can somehow get that manual you scanned to me, that would be awesome.
    I have photoshop and acrobat etc, so I might even be able to crunch it down in size without noticeably sacrificing quality too (well not too much anyway...).

    That is odd. The UI nitpicks I had are that (1) the outputs are not in ascending channel order (which is related to your first nitpick), (2) as a result of #1, the channel display order doesn't match the physical order, and (3) the channel label colors don't match the channel screen colors. :palm:

    Maybe Owon will at least fix the color mismatch in a future firmware update.

    Seems nice, overall, though. It's especially good to hear that it doesn't blow up circuits when powered on.

    I also have the U1242C's cousin U1282A (spawned by a U1273A Keysight recall) and it is very similar in size and I was told in functionality as well. They are great meters.

    While I did know that Peaktech does that, I didn't know that the original supply is the Owon one. Probably would have spared me some waiting time (and maybe even some money, the Owon seems to be less expensive...). One difference to the Owon: the Peaktech unit does not have binding posts, the connectors are recessed.

    I didn't notice the color issue until you told me. Probably because I was going by the orders of the channels, which match the buttons (but not the outputs). Interestingly the pictures Owon shows on their product page have matching colors on the screen.

    I bought a couple of reels of cheap 60/40 rosin core solder to replace the expensive 63/37 rosin core crap I tried and hated.

    I don't get it, the cheap stuff happily works really well at 330c-360c but the Loctite (formerly Multicore) spits like crazy even at 270c and just doesn't seem to adhere like rosin core solder should.  :palm:

    The 175/179 are the proven tanks of the DMM world. These days for the same or less $ you can get substantially better features, counts and accuracy (for example my U1242C), but there aren't many other (almost an industry standard in a way) DMMs around with the same proven track record for reliability. I've used ones which had been abused for years and years and have never encountered one that gave me any issues. Can't say the same for my very much not abused Agilent U1241A, which I've had to open a couple of times now (dodgy continuity buzzer and switch contact issues). I hope that my new U1242C fares better. Fluke will probably keep making and selling the 175/179 for a pretty penny for a long time yet.

    I just hit the debit card a bit harder than what I had originally intended for my bench DMM upgrade - a brand new Keysight 34460A (6.5 digit) is scheduled to arrive Tuesday.

    I am a big fan of Delta Elektronica power supplies not because they are dutch but because of their excellent service.
    Even if you purchased a PSU 2nd hand and some small thing is missing like a knob or stuff like that they sent it usually for free as service.
    Datasheets are no problem as long as the model is no longer for sale, so if you got the newest stuff you have to wait but some time you will get it.

    Same auction a cheap BK precision 9130 came along, so I had to have that one too.
    It is rather heavy and makes noise (fan) which are the only two things I do not like.
    Having three different voltage outputs from one PSU and with memory recallable settings is a new luxury for my shack, very nice esp when you have boards that need multiple voltages.

You may have a "special purpose" flux. Afaik I've seen an interactive page on loctite/multicore/whatever website with comparison charts helping to select the right product. But I don't have it at hand, sorry.

    For rosing flux I'd suggest try HS10 solder. It's fine.

    It sounds like a very mild low rosin flux, so for older/tarnished parts probably won't work well:

Fast soldering – range of activities to suit all applications. Good spread on copper, brass and nickel. Clear residues. Heat stable – low spitting. Mild odour.

    Actually, I can't recommend HS10 either. It's also quite mild and works only for "shiny" parts and may require finding a right soldering temperature to work well.

    I'd rather buy a solder wire without any flux as such fluxes have little to no specification (conductivity? corrosiveness? toxicity? "no clean" doesn't really mean anything, I have one wire with no-clean flux that causes severe headaches). I use fluxes that I tested (or others tested). For me it's no problem to apply "external" flux.

    @Falkra it is professional/industry laboratory power rail. It was a part of laboratory benchwork station. There was a lab. upgrade in company where i work, so i took it. It was marked as trash. Together with this i took 2cm wide bench desk with ESD coating included on top and socket for esd wrists.

    I am going to rebuild it for my own picture.

    @Mr. Scram

    so true. We have in labs wide range of different multimeters. However, Agilent 34401A (bloody keysight name!) rule them all. For long time measurements are those LCD screen beasts usefull because you can get a lot of statistics and direct loging of data. But for everything else - 34401A or Keithley 2 series or myyyyy precioussss Fluke 8842A.

    Can you elaborate why you consider the 34401A to rule them all? More usable, less drift or something else perhaps?

    TME Europe has up to 15% off on "Workplace Equipment". The offer ends today at some point .

    So, I bought the following among other stuff:

    1) Elme ESD Mat: 157CUT 6090 GREY

    2) C.K "Sensoplus" Pliers :

    a) T3772 1D120, Short snipe nose, serrated
    b) T3777D 150,   Long snipe nose, serrated
    c) T3770D 120,   Short flat nose, smooth
    d) T3771D 120,   Short round nose

    The pliers are made by Schmitz in Germany.
    I was ready to buy them from Schmitz. Now, I paid 10 euros less and I like more the C.K's handles in black-grey color.

    These are the equivalent part numbers by Schmitz:

    a) 4212HS22 (short snipe nose, serrated)
    b) 4202HS22 (long snipe nose, serrated)
    c) 4221HS22 (short flat nose, smooth)
    d) 4231HS22 (short round nose)

    member nanofrog recommends the Schmitz pliers all the time! I've read every single thread and posts before my decision. thanks! 8)

    That has got to be hands-down THE weirdest encoder/pot knob I have ever seen!!

    What is it with Japanese test gear and crazy purple housings? (Purple is my favorite color so I don’t mind that, but this and the Hakko designs are kinda nuts!) :p

    I am OK with the color,  the knob make me think of fig.  :-DD

    Well not purchased as such, but Fathers' day present. A nice pair of Tugsten Carbide side cutters - for all those magnetic component wires!

    No particular reason to suspect that they're not made in Germany, surprisingly nice quality!

    What motherboard do you recommend if you where starting over on Hackintosh?

    Greg

    =======
    I bought a used AMD Radeon RX 480 8GB reference graphics card for abut US$80 today. It comes with a factory overclock making it performing on par with the RX 580 in my Hackintosh. This card is used in my dual processor workstation replacing the GeForce GTX 1060 3GB, which is suffering under my 4K monitor.

    Wait so for each range it has a dedicated supply? Or is it putting them in series/parallel somehow. Interesting design.

    I like the way the guide on the box shows how you should employ the various diameters of the shaped handle. They missed out 'spanner zone' ;D

    Greg

    At this moment, you would want to run OS X 10.13 or 10.14 and the best motherboards are the 170, 270, 370 series.  My Z370 installed and runs flawlessly with a 6-core i7.  Every build I have constructed seems to be a little more trouble-free than the one before it...

    I got mine from Aliexpress (https://www.aliexpress.com/item/Original-Xiaomi-Mijia-Wiha-8-in-1-24-in-1-Precision-Screw-Driver-Kit-60HRC-Magnetic/32962744456.html (https://www.aliexpress.com/item/Original-Xiaomi-Mijia-Wiha-8-in-1-24-in-1-Precision-Screw-Driver-Kit-60HRC-Magnetic/32962744456.html)) and while shopping I spotted some apparently counterfeits around and sellers were even asking the original price for it and some time using the original pictures in the ad. I suggest to check the costumers' feedbacks with pictures to see what they are getting. The case's color of the fakes are darker, silkscreen of the bits is in a different position and the box is all white with no printing or sticks.
    For reference this is how a fake looks like (in this case the seller is not claiming it is a Xiaomi Wiha, but I saw others doing so): https://www.aliexpress.com/item/25-In-1-Multifunctional-Screwdriver-Kit-Precision-Magnetic-Bits-Daily-Use-Smart-Home-Work-Repair-Maintain/32957227636.html (https://www.aliexpress.com/item/25-In-1-Multifunctional-Screwdriver-Kit-Precision-Magnetic-Bits-Daily-Use-Smart-Home-Work-Repair-Maintain/32957227636.html)

    I got a fake set from a ebay seller. The sellers pictures were of the real item, but the seller sent me a fake. The fake had no markings or labels on the cardboard box or tool case. I compared the item I received with pictures of the real item. The biggest difference was the type of bits, and their placement in the case. The seller complained that the description stated that it was not the real item, but the title description actually stated "Wiha". I did receive a full refund and seller paid return shipping.

    I bought a real one from Banggood.

    I got the same Wiha/Xiaomi screwdriver set.
    It's very very good,but the problem with this kind of bits is "you can't go in to deep holes"
    However,Wiha/Xiaomi screwdriver set is the best of its own genre if compared to the others cheapo/bullshit set with this kind of bits

    So you get this.  Kind of a knockoff idea maybe, they do work though.  Between this and the original Wiha, I got rid of a small drawer of small screwdrivers in my toolbox in the office.  The tweezers are for crap so I pitched them.  Here is the link if interested.

    By the way, I bought both from Banggood.

    An insane medical quality set of fine tip cutters and tweezers. Accidentally discovered a desk with stuff in a local mall by the nail salon. There was a lot to choose from. If you live in Toronto check the local major malls. Found it at Centerpoint mall @Yonge-Steeles but they may sell in other parts of GTA too.

    Sure, it's also my first try, but the shipping costs are crazy and the parcel will be intercepted by the German Eagle (TM) that will add sales tax including on the shipping costs + an enormous delay :(.
    But it seem to be available at Digikey so next time I'll get something to reach the free shipping threshold, I'll get one if nobody will jump with an DE store that has human shipping price.

    TBH they are almost impossible to tell apart until you start using them. That said, the clone D24 is really chunky compared to the genuine Hakko and the coating on the clones isn't quite as nice imo.

    I haven't had a chance to use my Hakko calibration tool on it but I feel that the genuine Hakko tips are more consistent in maintaining temps, even the 1.6mm D tip which has less thermal mass.  I'd say the Hakko 1.6mm D tip is as good as the 2.4mm clone tip in this regard, and the 2.4mm Hakko is even better still. I dont want to sound too dramatic, but imo it's a noticeable step up.

    Nine boards like this! For *only* 30 Euro each + S/H! (the original price was 50 euro each)

    Two weeks ago I was asked to teach something in the local computer science campus, so now I can manage people in a little class, and give a development card to each participant.

    I am not a teacher, but this sounds like a cool experience. I am preparing a couple of examples in m68k/Coldfire-assembly and C  :D

    IMO for newbies you can better teach them ARM be it Cortex M, boards available as low as $10 upto whatever you want to spend if you include lcd etc. 68k is a bit obsolete although the principles stay the same.

    I was asked to teach a *classic architecture*, and 68k is the best choice. ARM will be considered for the Master Degree class, which is focused on advanced embedded programming, for which I have some working experience but no qualification as a teacher because I am not a teacher.

    My task is 20 hours in total, and it's available to be chosen but it's not an obligatory laboratory that a student needs to pass in order to pass an examination, while the ARM-programming-class is something like more than 40 hours and it's an obligatory laboratory.

    So, the *cool* factor is exactly teaching m68k, otherwise, the campus would have chosen a different candidate for the event :D

    Last what I've bought was Dewalt (DXAEPS2) and these baby works better than I was thinking about. And the main "bonus" of these cool things, that if you don't need to start the engine of your car (or other vehicles) it can be used as an air compressor. I was looking for such a multi-tool like it by more than a month before I've found one review (if interesting read this post here (https://bestfordriver.com/jump-starters/best-lithium-ion-jump-starter/)) which makes me believe that I must buy it. The price was $259 on Amazon with free shipping. So, I can add, if you or your friends need such stuff - recommend without any kind of warrings  ^-^

    I bought this... Before the Astro fanatics here ridicule me for buying a questionable budget device, I'm not into stargazing and my expectations are in line with what this can deliver. It's main purpose is to do some moon / near planet watching with my son (7) and my TEA doesn't extend to telescopes :) It was a return item too, which lowered the price even further, but unfortunately, the first buyer tried to tighten-up the mirror alignment screws and messed up the collimation, so I need to completely re-align it before I can watch anything further than the garden fence.

    I just bought yet another used PC. This machine features an Intel Atom D2550, 4GB RAM and 8GB SATA DOM. I am using this machine as my new home router, offloading the router task from my NAS. Also this allows me to shut down my NAS without losing Internet access. The NAS machine has been a bit too loud recently, so get that noise out is certainly helpful.

    I also bought yet another PC. The local surplus store (Tanner Electronics) was selling several NIB PCJr with several accessories (joysticks, decent keyboard, modem, etc.) for an absolute steal of US$60.00. I almost cried when I saw their ad at Facebook given I was in the middle of a trip. Fast forward 1-1/2 week, I stop by to buy something else and thought about asking if they still had one. Jim sold me his last one that was still NOS but no box and added a few extra goodies. I am a happy man!  :-+

    (yeah, I know the PCJr was not really great, but I am really nostalgic and will make a good company to both my Tandy 1400LT and Toshiba T2000 and other older Z80-based computers).

    I will upload pictures soon.

    While rummaging around in the basement I found an amusing item I bought at Target several years ago...

    Look carefully at the inches scale. Needless to say Target soon stopped carrying it. Don't know why... it's perfect for measuring jumper wires on a solderless breadboard.

    (0.1" between holes, 0.3" across the center divide, 0.27" to a power rail)

    I made mistake as I didn't "read" properly and didn't bother to look at the datasheets and thought they were 7200rpm.
    They also downspin to save power. Oh dear.

    Now it is too late at the time when I was investigating why they spin down.

    Some sites say 5400rpm (now I know) and others I think I ordered it from boast "up to 5x faster than with traditional 7200-RPM hard drives." that I misread and should have been more careful.

    Not the end of world as I already have something planned for them.

    Rules like that were common as "school rulers" in Australia (& maybe many other previously "Imperial" system countries).
    Graph paper was also normally scaled at 0.1" intervals.

    Workshop rules were always in intervals 1/2, 1/4, 1/8, 1/16 , etc, inches.

    After "Metrication", initially the use of "hybrid" scales like you have were frowned upon, but the school rulers still needed the 0.1" intervals, so after much lobbying, the Metrication Board allowed them.

    Generally speaking, the Knipex is very expensive stuff. For example, to pay $230 for a crimping tool which is supposed to be used a few times a year. That looks quite ridiculously.  :palm:
    So, I preffer to buy something similar from Taiwan, not more than $40~50... for the same stuff.  :-+ I will most likely lose that somewhere at field than It will became worn or broken.

    Ordered a Nepros stubby 1/4" drive ratchet among a few other things. You can attach a breaker bar to this which kind of makes it act like a flex head ratchet, very useful for hard to access bolts.

    Knipex has way cheaper crimping tools. In fact, you don't have to spend $40 for the cheaper models. You just picked the ultra fancy luxury model. Knipex is not cheap, but also not that expensive.

    I have no idea why you are harping on the price of the brand chosen by the other guy... There's nothing new on the world of tooling: a seemingly simple tool can cost hundreds due to other hidden factors tied to downtime (if the tool breaks too easily under continuous heavy usage), warranty/maintenance contracts (on the spot replacements), standard tolerances and/or compliance, type of customer, etc.

    3M is known to have these as well:

    That's exactly my thoughts, everytime I get some gear to fix that arrives without a power plug, but the Quick Tester costs €65 here, which puts me off. Is there a cheaper way to get one?

    Got a few new (to me) pieces over the last few weeks:

    Keithley 181 Nanovoltmeter (with mV cables!)
    HP 6274B DC power supply (with 50V 20A 900W option)
    Tek 2335 "portable" 100MHz 2ch oscilloscope

    The Keithley and HP from a very nice gentleman who had a big electronics businesses that he closed down a few years back and that I had the pleasure of spending an afternoon with during which he shared a lot of fun stories from the trenches. Great learning experience for an amateur like myself!

    Don't have any good plans for the things yet. Any fun ideas to share what to do with a Nanovoltmeter (wanted a bench multimeter really but he didn't have any suitable) and somewhat higher output DC supply? :)

    Totally reasonable. Around $120 for a pack for 200 A6 prints (both ribbon and paper), or $80 for 240 10x9cm prints.

    This is a (medical) photo printer, you can't re-transfer from the photo paper.

    Dye sublimation for transfers doesn't use dye sublimation in the printer. Instead, another printing technology (like inkjet) is used to print the "raw" dye-sub ink onto transfer paper. Then the transfer paper is pressed under heat to the final product (e.g. fabric), which is where the dye sublimation process occurs. The diffusion that happens in this step causes the tiny inkjet droplets to blur, resulting in a smooth, continuous-tone print on the final product.

    In a dye-sub photo printer, the dye-sub ink is already deposited onto a ribbon, and then a thermal printhead sublimates it onto the paper, so the print is the final product.

    It's a PlasmaEtch PlasmaWand http://www.plasmaetch.com/atmospheric-plasma-wand-cleaner.php (http://www.plasmaetch.com/atmospheric-plasma-wand-cleaner.php), which is just a rebadge of a Relyon Piezobrush https://www.relyon-plasma.com/relyon-plasma-products/piezobrush-pz2/?lang=en (https://www.relyon-plasma.com/relyon-plasma-products/piezobrush-pz2/?lang=en).

    I think the price is about $3800, but I got it on ePay for $1200 with one hour of use.  It's not cheap!  Generates a lot of ozone and really stinks up the air, but it's cool.

    Totally reasonable. Around $120 for a pack for 200 A6 prints (both ribbon and paper), or $80 for 240 10x9cm prints.

    Why do I get a mental image of the walls at your place being plastered over with A6-sized photo-quality prints?  ;D

    (Oh, I know.  That's what I'd do.  Tiled images of real and unreal places and stuff, maybe like small windows or ports...  Just do a DuckDuckGo image search on Plitvice (https://duckduckgo.com/?q=plitvice&t=canonical&iax=images&ia=images&iaf=size%3ALarge) to see what I mean.  I wonder how large a rounded icosahedron you could make, with the surface of Mars printed on it, without wasting too much space on those A6 sheets?)

    The irony is that I used to do a lot more photography as a hobby, and I have tons of photos that I’ve been intending for 15 years (and counting) to print and frame. I have a great printer, great photo paper... and not one single photo printed and framed. Not one single photo of any kind on a wall! :(

    I took a chance on an E9300A RF power sensor from eBay "for parts" at about $60. This is a 18GHz dual path diode-based sensor. So far, the connector gaged at 208.8 thou pin depth (seems good, looks like standard N is .208 deep while precision N is .207 deep.) and holds zero within spec, and properly cals. There is no public calibration guide that I can find, perhaps I will compare a siggen's output using another sensor against this one. Comparing to a 8656B siggen at 50 MHz and  950MHz, everything is within 0.2dB from -60 to 10 dBm, so yay, both diodes paths work.

    I don't have a N-type cal kit, so I may measure gamma using a calibrated 3.5mm port with port extension as adapter removal. Gamma tables used to be printed on the sensors, but not with the E series. Is there a way to read the cal table from the EEPROM?

    EDIT: Nevermind my question, seems like some code to read the EEPROM has been posted (http://www.ni.com/example/25526/en/).

    Some cheap storage.

    Amazon is doing a limited time offer today and Sabrent has a $255 2TB USB 3.1 NVMe SSD for sale, so I grabbed it.

    The bare M2 drive itself is $220, also on sale. This is a TLC drive with 3115 TBW endurance, yet the price is comparable with Intel and Samsung's QLC drives.

    Not a bad idea for a quiet local backup drive and video scratch disk.

    https://www.amazon.com/dp/B07MTQTNVR (https://www.amazon.com/dp/B07MTQTNVR)
    How does it perform though...

    I have actually never really used any TLC or QLC drives. All my SSD's, especially the better ones, uses MLC. I have heard that TLC and QLC has longevity problems and are much slower than SLC and MLC devices.

    I didn't really buy this, rather it was in a box of random devices that I bought. Monacor FSI-117 - An SWR Meter / Dummy load with a few other tricks up its sleeve for the 11m enthusiast. It seems to work fine, but I don't do any radio and have no other uses for it, so it's just going to be a pretty ornament for now unless someone here wants it.
    The picture isn't my one, but is in the same condition.

    Haha, didn’t even notice that. It was just printed straight from the pdf document, so no editing was involved.  Tektronix probably wouldn’t like me editing their IP anyways, but just so I don’t try and sale copies of it, I doubt they care that I made a book from it.

    It was: https://www.prestophoto.com (https://www.prestophoto.com)

    As to the hardback, I'm unsure. This particular one was printed as a "Textbook". When I originally looked at the Textbook options, there was one for hardback.  But after I uploaded the PDF and was  ready to check out, the hardback option was no longer there.  So, unsure if the PDF I uploaded didn't meet some kind of size/length requirement or what.

    If you ever reprint that book, if you insert a single blank page (The old "This page intentionally left blank") at the start of the PDF (not a whole leaf, just a single page), it'll push the pages along one and put the numbers at the outer edge. ;)

    That is a good catch, but after examining the book closer, you do need more than one inserts before certain sections.  Sections 1/2 are fine (but only because I used second page as back cover), section 3/4 needs an insert, and section 5 is fine.  I just happen to take a picture from section 3 I think.  Also probably why I didn't immediately notice the page thing, since it looked fine from my first glance (and I just opened to a random page to snap a pic).

    If that site would let me print a hardcover in A4, I might consider redoing it, but looks like 6"x9" is as large as they offer for "Textbook" printing. Just not interested in a smaller size. I looked at a couple alternative sites, but one was wanting ~$100 for a single printing.

    Regardless the book has section headings on the outer-edges for nearly every page, so it really is a non-issue for me. If I consider printing another PDF though, I will be a bit more careful about the page numbering.

    A piece of retro data storage gear. A HP 82901M  - dual 5.25" floppy disk unit with HP-IB interface.
    Not because I needed it; more because it became available for a good price, is fairly rare, and will be compatible with a setup I'm trying to arrange, to drive other HP-IB storage devices.

    Pic is after cleaning and a few small fixes.

    Without looking it up, who can guess how many K-bytes this thing gets on a floppy?

    Introduced in 1980, obsoleted in March of 1985
    This is SN: 2101A11418, made around June 1982.

    The PDF of the service manual I found at bitsavers is pretty bad, both quality and seeming to be for an earlier model (or had very poor accuracy checking.) So I'm looking for an original, or better PDF

    Edit to add:
    Density: Double sided, 35 tracks/side, 16 sectors, 256 byte sectors, MFM, hard sectored.
    Total capacity: 286,720 bytes. (280KB)   Totally proprietary HP file structure.

    It powers up, completes self test, sequentially inits both drives, and does respond on the HP-IB bus. But I don't yet have something that can talk with it properly and R/W files.

    Update: better photos. BTW, they appear here in reverse order to that entered. Bug in the new photo upload feature?

    Today, a Piece of electronic and a not so electronic:

    [attachimg=1]

    OnePlus 6T 8GB/256GB to use my China Mobile SIM Card, since my old Iphone 5S is not Unlocked, and the battery from it is starting to swollen, I need to change it but I'm waiting for my toolkit to arrive from Portugal here. Yes the Oneplus 7 is out already, but got this one with an heavy discount, and it's more than enough for my needs.

    The other one is one of my Passions, Watches. This is the Seiko 5 SNZG17J1 Sports Automatic Movement watch, no battery needed since the winding is made by the movement while using it, with reserve for 40 hour full winded.

    I retrofitted with a WatchGecko Nato G10 Strap in Black, removing the Metal Links with Clasp one that came originally. The watch itself it's a model that it's already non being manufacture, but for a daily driver / beater watch is enough instead of using my other most expensive ones.

    Yes, normally as beater most used the typical Casio F-91W if you want a reliable cheap Quartz movement or the Seiko 5 SNK803 that it's a $60 watch. I used a Casio F-91W for years, since I was 12, but I can really get used to the digital numbering. I'm fond of the typical analog movement instead of the digital one.

    But being that this one is no more manufactured it's a good all around watch for everyday use. I call it beater but in reality I'm someone who takes care with my watches, for example if I'm working in places were the watch could hit something and get scratches I normally take out. Even being a beater is still something I want to keep pristine the max time possible.

    I current use a OnePlus 5, and I'm very happy with it. Fast, all-day-long battery, and dual SIM (I have a T-Mobile for daily use, and a China Unicom for receiving Chinese verification codes).

    I think of put the Portuguese SIM card here too, and have a phone for both things, but I still have a lot of people that uses iPhones and iMessage, so it stays in the iPhone until I have a reliable equivalent official app on Android OS. I'm more turned into getting a Google FI SIM card and register here to that way have a good price for Roaming when I go to Hong Kong or move around the World. Of course Google FI only it's sold in the USA and I didn't got there to buy one yet. The sellers that I found on eBay don't ship to China because they say the shipping costs are more expensive that the card itself.

    I moved away from battery-powered watches. Automatic or solar for me (granted solar watches have batteries, but I don't have to change them every couple of years).

    Yes, I've noticed that.

    Here's a pic of the gateway drug:
    (https://photos.smugmug.com/Other/Miscellaneous/i-Ws8pqrG/0/14493a0f/M/Seiko%20SRPC91%2003-M.jpg)

    It relieved my long suffering and battered Citizen Eco-Drive from its toil.  I need to get the crystal on the Citizen changed, as it's rather scratched from about 12-13 years of daily wear.  I haven't photographed the Kamasu yet, but it has a nice rich red face that's more understated than the shimmery blue one on the Seiko.

    Oh, yes it is.  This one is 180 degrees opposite of the first one.  Truly a blessing who I tried to tell her that I wasn't interested in a relationship and that I was too old for her.  She was a persistent one, she was.  Yes, indeed.  Glad she didn't listen to me.  She has accepted me with all of my foibles and she as helped me to grow as a husband, step-father and man.  I tell her every day that I am thankful and grateful for her and I also try to show her every day how I feel about her.

    I've done that yes, and exactly that same thing... Now I simply say " You know, I know I will lose anyway but still didn't... (bla bla bla bla). That's my point. Just tell me when it arrives for me to pickup in the postal box."

    She plays me like a fiddle. But she's a great wife, I'm not really regretting having her!

    I don't even bother asking my wife about her expenditure on shoes and handbags and she doesn't ask me about spending on tools and retro computers. We both have an agreed monthly allowance each which makes the whole thing painless.

    In other News... I Have a Little TEA to Share!!!

    eBay auction: #133017269362   My LAMBDA LQ-532s arrived on Thursday; aside from shooting a few quick pix as I unpacked it, haven't had a chance to do anything with 'em til today.

    (https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/?action=dlattach;attach=784155;image)   (https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/?action=dlattach;attach=784161;image)   (https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/?action=dlattach;attach=784167;image)   (https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/?action=dlattach;attach=784173;image)   (https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/?action=dlattach;attach=784179;image)   

    1) Just as I found them when I lifted the nice, heavy double-wall carton full of HDPE foam off the top; aside from not having anything between the two units, they were definitely packed with plenty of heavy duty stuffing.  :-+

    2) Damn. I REALLY wish they had put something between the two. All those little scars are new from their trip to my home. |O Good thing these things are built literally like a tank.  :-\

    3) Both these units are unbelievably clean, inside & out. Aside from the sticker residue that was shown in the auction photos, no dirt or blems except a little shelf wear. One of them actually has the feet & HP-style prop kit! :-+

    4) A close-up of all that delicious heavy metal. Look at that lovely map of all the POIs.  :-DD I did some quick continuity tests to make sure no dead shorts where there obviously shouldn't be any; all negative both units.  :-+

    5) The voltage pot is a 10-turn; no idea why they didn't do the same on the current limit, but oh well. I can always add that at a later date; I have oodles in numerous sizes from my homebrew PSU project.
    Not bad for two little piggies right out of the poke; and $66 for the pair is definitely a NICE price!  ;D For this deal on THESE juiceboxes, I'll MAKE room... If I have to put them under my feet all the way to Toronto. :-DD

    There's more pics and discussion on these  at the original post in our TEA thread here. (https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/msg2545176/#msg2545176)

    (https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/?action=dlattach;attach=526388;image)   Yeah; the Ragu 17b was a "thing" a while back; a vendor had them on Amazon for $9.99 delivered so I got one just to see if a lump of coal came in the box. They're actually a fair meter; IIRC it uses the same DM1106EN chipset as the ANENG AN8008, but with a few firmware glitches in the uA/mA ranges as others discussed somewhere around here on the ANENG AN800x thread. (https://www.eevblog.com/forum/testgear/an8008-us-$19-10000count-1uv-0-01ua-0-01ohm-resolution-meter/600/) It's a good enough low-voltage meter (I include US domestic mains 120VAC in that category) as a second for when I "want to do something stupid" without risking my 189/3478A, or to do V/A at the same time quick & easy. But my little test stand (a 2-day print of my own design) (https://youtu.be/5JZDlFrkT88) is NEVER that tidy anymore.  :palm:

    I remember some years ago, Sam's Club selling something very similar.  Used to kind of drool on it a bit.  Haven't seen it in a very long time.  They still show a 26" on their website but I haven't seen it in the store.

    My wife found one like this for me at COSTCO and surprised me with for my birthday about 15 years ago; it's the biggest one CSPS ever made (https://www.csps.tw/toolbox-e) at 56" x 61" and 23 drawers. Too bad you can't buy them at COSTCO anymore...  |O

    Same happened to me. I got two of them and they are just amazing, especially for the price at the time.
    The only thing I changed was to take all aluminum handles off and had them red anodized. It looks so cool!

    The Power Supply seller 'Digilife' and their packaging makes me wonder if they used to work for Digikey or if they are an offshoot.  :palm:

    It could be worse. I received some years ago a PC component with the original box of the component only. So basically pick up the component, and instead of put inside another box, no simply stuck the shipping sticker on it and off it goes! At least you have some protection...

    Not Arrow but Mouser is 'special' too along with this Digikey one. 2x LTZ1000's .....

    The Case has now turned up so just the GPU to go but I can do most of the rest now.

    You can try to learn using macOS on this. If you have the CS foundation you will find macOS a solid UNIX distribution, capable of replacing Linux in some cases. Also do install Xcode, XQuartz and homebrew for maximum code compatibility with Linux.

    Mac Mini was always a bit underwhelming to me somehow. The hardware is underperforming and it is not justifying the cost. Should there be an Intel NUC that uses socketed wireless module (so a genuine Apple wireless module can be used for proper Wi-Fi and Bluetooth support, as well as allowing the use of Continuity and Handoff) that can make a better small form factor macOS machine with Hackintosh. Bonus point if it is the ones with AMD RX Vega graphics as Apple never had a Mac Mini that has a dedicated GPU but macOS does support those built-in chipsets.

    The mini — other than that weird phase where Apple didn't update it for years — is certainly not "underperforming" for tasks that don't need the power of a dedicated GPU. Where'd you get that idea? You wouldn't use a mini as a high-end workstation, but for most things, they're just as capable as an iMac, or the MacBook Air, which is Apple's most popular model. And of course, with Thunderbolt, you can use an external GPU with it if you want.

    My current desktop is a 2008 Mac Pro, which is clearly showing its age. With the new Mac Pro being a much higher end workstation than the 2008 model, there's no way I can justify getting a new Mac Pro, so I'll either end up with an iMac, or with a new Mac mini and some kind of NAS or external RAID enclosure for all the drives. (Internal drives are the thing I'll miss most. USB drives are never quite as reliable, e.g. when going to sleep.)

    My Daily driver is a late 2012 i7 Mini and it's still serving me well - adding a 120GB Samsung 840 PRO SSD a few years back (in Fusion mode with the 1TB) made a massive difference to it and gave it a whole new lease on life.

    What I mean is it is underperforming for its price, and it is not user upgradeable. Previous Mac Mini's (and MacBook Pro for that matter) are at least partially user upgradeable even though it means voiding warranty, but recent models started soldering down components like storage and memory, forcing me to pay for the Apple tax on upgrade components. Also it makes recovery a nightmare.

    That is why I brought up Intel NUC as a comparison. NUCs are user upgradeable.

    When I bought my 2011 MacBook Pro I bought it with maxed out CPU (it is the 13-inch model so integrated GPU only anyway) but base memory and storage, and three days after I bought the machine I upgraded its memory and storage. This upgrade surpassed the maximum offer from Apple and is cheaper. Also back then those MacBook Pro's can be upgraded without affecting warranty. As of now my main Apple computer is a 2012 MacBook Pro, with 16GB memory and 1TB Samsung 850 Evo SSD. My daily driver is a Hackintosh though, with base hardware about equivalent to the top-of-the-line 2014 iMac and a RX 580 graphics card (slightly better than the Radeon Pro 580 in base 2018 Mac Pro)

    I upgraded mine from 8GB to 32GB. It's certainly doable.
    SSD is soldered down, though.
    That soldered down SSD is a major gripe for me. If you went with the previous generation even the memory chips are soldered down.

    Apple is not a fan of standard interfaces really... However there are adapters that allows insallation of standard M.2 drives in certain Mac models, include some older Mac Mini's that does not have soldered down storage.

    Depending on how much are you willing to pay, there are Thunderbolt 3 to M2 adapters that can give you ~22Gbps of BW for $160, still way cheaper than Apple tax on higher capacity upgrades.
    Then I would buy a used unit with both memory and storage not soldered down, then install maxed out memory, that Apple proprietary to NVMe adapter and a standard NVMe drive in it. This is even cheaper although I miss out the warranty. Or Hackintosh on a NUC which is really about the same.

    You do realize the 2018 MacMini actually has a full desktop 65W CPU? With a bit of modification (liquid metal TIM, RAM upgrade), you get a stupidly fast tiny computer that leaves all NUCs far behind.
    The storage upgrades are stupid expensive though. I have 1.3TB of data on my current Hackintosh, and that means I am pegged at the 2TB option and no upgrade path.

    Quote from: blueskull on July 18, 2019, 07:43:36 am
    Also, Apple certainly knows who is using genuine hardware and who is not. If Apple desires so, they can roll out an OS update that nukes all Hackintosh computers in no time.
    They have no incentive to do that though, as they know what kind of people are using Hackintoshes - the last crowd of people they want to alienate are the power users.

    AFAIK that list on Apple website about Metal-compatible graphics cards for 2009/2010 Mac Pro and eGPU comes from Hackintosh community's reports. So keeping Hackintosh community alive means Apple have a crowd of volunteer product testers, mostly power users or better, providing them free R&D.

    Apple’s SSD pricing is high, but people often forget that it’s insanely fast SSD storage. Granted, even SATA SSD speed is more than adequate for many tasks, but the latest Macs with large T2-based SSDs have storage bandwidth approaching the RAM bandwidth of my 2008 Mac Pro!! (The 2018 mini has 3.4GB/sec SSD bandwidth, versus the 7.5GB/sec best-case scenario for RAM on the 2008 Pro.)

It's the motion sensor and 2.4" IPS display module I've been waiting for too.  These aren't the first registered eBay package they've "lost", either.  Dammit, now I have to go there and raise some noise, probably do some paperwork too, and I hate that.

    Edited a few hours later:  Apparently, looking like an angry potato with a voice to match helps.  It did take a good fifteen minutes, but they discovered they had "accidentally misplaced the packages to the wrong shelf" (believe if you will), and now I have my packages.  I ought to be :D but am >:(, because I really REALLY hate thieves and exploiters.

    If you find it keeps disconnecting itself from the internet for no reason, then let me know... I've fought that battle and (semi) won :)

    McBryce.
    I fought that battle too. Ended up switching to a full TP-Link enterprise grade stack: a TL-SG3226PE PoE switch to power the AP's (and allow PoE on all wall Ethernet jacks in my apartment,) a TL-AC100 wireless controller for central management and proper Wi-Fi roaming, and three TL-AP1205GI-PoE wall panel access points in thin AP mode. For the sake of smooth Wi-Fi roaming I have even switch the security options to WPA2 Enterprise, with a RADIUS server running on a Raspberry Pi.

    My apartment has a foot-thick reinforced concrete wall in the middle of it, blocking any RF signal from penetrating from one side to the other, thus when renovating it is fully wired up with Category 6a cables for Internet access.

    My issues weren't with the WiFi, it was the connection between the router and my service provider. The router disconnected itself every 10 minutes for no apparent reason.

    today, i had nice email. It started like : dear colleagues, our furniture in our offices are going to replace for new one. You can take furniture marked with pink strip to home for free, otherwise it will be thrown away...

    So, i bribe two colleagues with ice cream for moving and i have new desk, locker and esd chair in my appartment :) Desk is 180x80cm, steel body,height adjustment and power distribution rail under desk. Locker is 100x100x40, both of them Konig and Neurath company. And ESD chair, dunno, but, who cares.

      Well,  I did get 10 of them for the price of one from digikey. But that was not the intent. I also have a few from Mousdr that I bought.

      My line of thought was that I want some aged AD587s to see how they compare to the new ones in terms of drift and noise.

    Not TEA but tool related.  Mrs GreyWoolfe continued her greatness by allowing me to upgrade my old HF compressor to a Husky 30 gallon, 5.3 CFM @ 90 PSI compressor.  You can see it is outfitted with an Ingersol Rand ARO air filter attached with a 5.5" brass NPT nipple and Milton HIGHPROFLO V series high volume quick connects, as are all the air tools.  I also have the Husky extended drain that will go on after I do an oil change.  I don't really want to tilt the compressor over with oil in it.  Break in went fine and it rolls off lug nuts with my 1/2" impact wrench.  The other thing most notable is that it is quieter than my HF compressor.  That is quite nice.

    Much thanks goes to mnementh, my co-worker and my son for helping me make the decision on the compressor and accessories.  mnem, you were spot on with the Milton connectors, what a difference.  Hopefully, it will last as long as my HF toy compressor.  That will be going up for sale with some extra stuff for cheap for a quick sale.

    I was looking for a used spectrum analyzer that wasn't too old and had a resolution bandwidth of not more than 1 Hz.  I found something which met those qualifications, plus had a variety of additional features at a good price.  It was an Anritsu MT8222A Base Station Analyzer.  The features that it came with (some standard, some optional) included:
    I have a picture attached of the unit, plus one of a Spectrogram from it on some of the local DTV signals.

    I also have a view of it in the Cable and Antenna Analyzer mode functioning as a spectrum analyzer with a tracking generator.  I was evaluating a new model Pulse CX2040LNL RF transformer.  It is rated for use between 1.5 - 500 MHz (+/-3 dB).  Those displays were taken with the MT8222A and the excellent Anritsu software.

    While the MT8222A and B are no longer available, the MT8220T is still available with similar features plus additional cell phone features.

    So far it rates as an excellent purchase!

    Glad I could help, my friend. The V-Style connectors also seal better and last longer before the rubber bit starts to hiss at you when you move the tool around, compared to the ubiquitous "M" style and Aro couplers from days passed.

    The Anritsu MT8222A Spectrogram with my prior message looks pixelated due to changes in the signal's amplitude with time and due to multi-path reception.  I thought that I would prompt that color change by rotating my receive antenna.  So, today's Spectrogram attachment shows reception with the antenna first pointed south, then southeast, next east-northeast and finally west-southwest.  Sometimes the color change is due to my antenna's directivity with the same station while at other times a different station is being received.  Channel 23 shows an example of at different headings, three different stations were being received.

    At the lower edge of each signal, you can see a pilot stronger in amplitude than the main signal.  Some stations have this pilot's frequency controlled by the GPS satellite.  When that is the case the pilot will be precisely 309.440559 kHz above the lower edge of a station's 6 MHz bandwidth.  An example of where that is the case for a local station on channel 22 is shown on the second attachment.  With the spectrum analyzer set for 100 Hz bandwidth and both a RBW and VBW of 1 Hz, you can see that pilot just below 518.309441 MHz on my GPS locked MT8222A.  It demonstrates how broadcast stations with GPS receivers connected to their exciters can be used as frequency references.  But remember, not all stations have GPS receivers in use.

Hmmmm, the jury is still out on this one. They really need to work on the firmware, time will tell whether this one grows on me.

    I hope it stops smelling like the back entrance of a chemical factory soon too!

    So, to watch on signals remotely ~ 30 m it needs to be used two usb-rs232 converter/amplifier, due to usb specification limitations. Or?

    I wouldn't get all wet over a SHS, sure they're a handy little tool but you'd be far better off battery powering a 4ch X-E and then use its LAN or WiFi for remote usage.

    Finally decided to enter the 21st century and order a hot air station and stereo microscope.

    Quick 861DW from Taobao, approx 320 dollarydoos delivered (and a few bent nozzles about $11 each). Should be more than good enough for my occasional use if the reviews by Louis Rossmann and the Second Best Amp Hour Podcast host is anything to go by.  ^-^

    The microscope was a bit more tricky to decide on. I went with an old Meiji EMT microscope (~AUD210), it's basically the model that all the Chinese clones are based off. I wanted to go for a zoom model instead (Meiji EMZ, Nikon SMZ, Olympus VMZ) but the used market kinda sucks here, oh well.

    Part of me wishes I shelled out more for a new zoomable microscope from China like an Amscope/Omano but ehhhh I'm a sucker for old quality gear. It's not like I have to rework boards 24/7 so I think I can live with the two 1X and 3X objective levels. The 80mm working distance might be a pain, and I don't reaaally want to spend another $200 on a 0.5X barlow, I'll just deal with it.

    Well yes then the SHS is the best for this from our line.
    I had an 806 like McBryce for a while but didn't use it hardly at all as the modern DSO is quite portable enough for my needs.

    It's a shame.  I think the unit had a lot of potential, but it really seems that Siglent has let it linger for far too long.  The UI is really just not very good, and the use case described is about the only one that would make getting one worthwhile.  Even the 6000 count DMM portion is rather lackluster.   

    There is one saving grace:

    judging on the pic attached it's upgraded from SHS806 --> SHS815. Didn't it?

    Yes, but not HOW it's done.

    Just ordered a new Netgear R7800 wifi router to improve wifi coverage to the garage.

    https://c1.neweggimages.com/NeweggImage/ProductImage/33-122-818-07.jpg (https://c1.neweggimages.com/NeweggImage/ProductImage/33-122-818-07.jpg)

    If you find it keeps disconnecting itself from the internet for no reason, then let me know... I've fought that battle and (semi) won :)

    McBryce.

    Out of curiosity, are you using PPPoE authentication on your Netgear?

    Yup.

    McBryce.

    So it arrived a couple of days ago (from Germany, damn DHL is fast!) and it's been completely flawless so far (and a great upgrade over my R7000). I thought I needed to use PPPoE to authenticate, but it turns out NBN use VLAN tagging on FTTC, so your router just runs in straight DHCP mode.

    It's so nice to go from 12/1Mbps ADSL2 to 100/40 Mbps FTTC - it feels like I finally joined the 21st freakin century!!!  :scared:

    A couple of days ago I bought myself a new monitor. My old 19" IIyama lcd screen was still working ok but the resolution and size was becoming unbearable.
    After using it for a couple of days, the only thing I regret is, why didn't I buy it years before?
    I also like very much the possibility to automatically adjust the brightness depending on the ambient light (it has a sensor for that).

    Personally, I think that sort of juvenile stuff doesn’t belong on an HP calculator.  That’s more the domain of things that have an = button.

    I’m in the middle of a major hitting and rebuilding of my work area in the basement at home and I bought these recently on sale.  Hopefully with the long weekend, I’ll be able to get them put together and get my benches set up the way I’ve got them envisioned now.

    I've got one of those. I bought it new. A long time ago. Best calculator I ever had. Batteries last crazy long time. The last set of batteries were 13 years old and still working good. I got freaked out thinking they might leak, being that old, so I replaced them anyway. The batteries are just 3 little button cells.

    I have designed a USB PC oscilloscope and so bought some pcb's from JLCPCB.
    Its runs about 10MHz and uses a cheap PIC micro and a AD9200 20MHz A2D.
    The front end is standard 1m+10pf input.
    Voltage range is changed using a 74HC4051.
    The PC end is the clever end doing all the display maths and functions plus a fast fourier transform for frequency display.
    My PCB design, CAD software is PCBCAD360.

    Recently I got a good deal from eBay for a JST crimper. Background: For a project I needed a compact connector with gold plated contacts which you can actually buy. It turned out my choice is limited to the JST SH 1mm pitch series. It is funny (NOT!) how there are so many connectors and in the end so few options to fit a particular use case. With no pre-crimped wires available I had to find a crimper. A cheap crimper from Iwiss didn't work because the jaw for the 1mm pitch contacts is too wide so the contacts don't fit in the housing. Crap! The official crimper from JST costs $1100 and that is a tad too much to spend on making some test cables. But I didn't want to change the connector either. So I went onto eBay in a last ditch attempt and lo and behold I managed to scoop up the official crimper from JST for $140 (+ shipping) in used condition.
    (https://i.ebayimg.com/images/g/ZZ0AAOSwGxBdMIks/s-l1600.jpg)
    I already received & tested it and it is in good working order. Crimps with the official tools are always the best but the official tools can be horribly expensive.

    You are lucky! Those crimpers are notorious of being sold extremely high priced in working condition.
    All those screws on them are to finetune the different parameters and if some dumbo has played with those it is IME a nightmare to get it back in perfectly working condition.

    Amen! If silicon manufacturers would do this and make different packages for their generic glue/jellybean stuff all hell would break loose but if you are a connector manufacturer, suddenly standardization and interchangeability is not a major requirement.

    It's probably alluding to the Greek word "Eros" which, IIRC, was the son of Aphrodite and it was himself known as the god of love. This word is the root for "erotic" and similar words.

    Thus, this would be an erotic tantalum capacitor...

    I got an Adaptec APA1480 to add mobility to a Tektronix TWD 120 that I got a bit ago. This will allow me to get it running on a hand-me-down Windows XP laptop (Inspiron 2200).

    Apart from this, I got a CF to IDE 44 pins adapter to get an old Toshiba T2000SX going - it seems the adapter is not powering the CF card, though... Still investigating.

    Got one of these CF to IDE a while back. I remember issues to make sure the connector was in the proper orientation as it could be connected in reverse.
    Second was a jumper for master/slave. I also had to supply a 5V with a bodge or solder wire between two pads on the adapter and make sure the card was bootable (not all cf cards are).

    Tekwiki says it's an S-4 with an attached photodiode. So by removing the photodiode one can get a S-4 (which isn't totally useless if you have the 7S11/7T11  or 7S12).

    Thanks for the heads up; I did some verification and found out that two probable causes are at play: either a bad flat flex cable or the inability of the BIOS to acknowledge anything other than the Conner drivers that shipped with this thing: CP-2024 (20MB) and CP-2044 (40MB). Still investigating...

    On the other hand, the APA-1480 works wonders on the laptop plus the TWD 120. That is a real controller!  :-+

    I would like to say I brought a box of vintage PC hardware really cheap but it was all mine and long forgotten about  :palm:

    WiFi cards and USB external range extenders underneath assorted HDD the best of which is a newish 200GB the rest are pulls from scrapped family and business systems and really need a proper disposal of. 250Mb Graphics card from maybe W98 era at nearly $200 from my scratchy memory and lots more goodies. Even the 3 1.2" FDD has had it's day as you can now get emulators for pen drives. My new build didn't even get a consideration for a DVD burner as they are about toast too. Several DSL 1 and 2 modems and routers as well in box number two.

    Time for a new thread TOSS Techgear Obsessive Storage Survivors.  ;D

    I have a similar collection too, but it is not acquired in one lot like this, but a slow accumulation of components from computer upgrades over time. I have newer things like a working Gigabyte Z97 motherboard and a GTX 1060 3GB graphics card, also some ancient things like a GeForce 256 AGP.

    I have the same one, but I always thought those snaps there were for storing the end of the attachment wire when you get up so they are out of the way. I don't think they are for grounding.

    Had another think about it last night and you are likely correct about storage. With my cheapy mat and being mounted along the front of the bench the studs being more flush suit better in my case to keep my legs from wiping it out.

    Aluminium wire in the leads is a potential PITA for others but crimped fine for me with a little strain relief.

    Yeah... the bracket is meant to be screwed to the bottom of your over-bench shelf and provide a convenient place to plug in the banana end of the coiled cable. The snap end goes on the mat or on you; those snaps are just to have a place to put the other end out of the way when you're not using them.

    Not far off the mark for it's initial use. I was rebuilding the timber parts of a very old crystal radio. Was also used for keeping the coils likely suspect insulation in operational order. Generally I have used the beetles for timber but from time to time electrical insulation goop it has done well too.

    That's how I do it.  I grabbed a cheap plug end from the big box hardware store and removed the hot and neutral pins.  I added a small banana jack and put a banana plug on the wire.

    I don't think many people have an actual grounding rod in the lab. Just make sure you have ground and not neutral or even live.

    Yep into the Earth pin on the supply. That said in Oz we have now got earth fault protection switches on the circuits and before that I have lived in older houses that the 'Earth' was not at ground potential  :o Generally only a few volts off but still not zero. Separate ground stakes are better but not always practical.

    I think that's a good price for the mix of features: IPS, QHD, HDR, DCI-P3 color space, high refresh rate.

    This week I also bought a new monitor, a Philips 326M6FJSB.
    (https://c1.neweggimages.com/ProductImageCompressAll1280/24-133-407-V17.jpg)
    It is also QHD (2K) but 32" so it maintains the same-ish DPI as my previous FHD monitor. I paid less (~$300 USD) but everything other than size is lower spec that yours. No HDR, but color gamut is wide, just shy of DCI-P3. Refresh rate of 75 Hz isn't gamer-spec but works for me. My somewhat older RX480 video card can still push all those pixels at 55 to 75 FPS (SW Battlefront 2) and with Freesync, it looks smooth as butter to me. It has "Ambiglow" which is a row of RGB LEDs under the monitor to provide ambient light matching the dominant colors on-screen. Gimicky, but I have not turned it off yet. I had chosen this monitor for the wide gamut, IPS panel, but I really like the Freesync feature that I didn't know I needed until I saw the huge difference it makes.  I had also tried an LG 32" 4K monitor with a VA panel (also DCI-P3 color), but found the colors became too washed-out off-center and couldn't get over that so I returned it.

    Speaker protection has come a long way.  In the early days when all we had was overvoltage/current detection (which would shut the amp down but not handle the kickback from the speaker), it was scary noises and/or possible destruction every time something misbehaved.  Then people started being smarter about the protection circuitry, to the point that other than deliberately driving the speaker beyond its ratings it's now hard to fry something.  Allegedly, the Crowns will take inductive current spikes from the speaker and "recycle" them without tripping the protection.  And their peak limiters don't seem to affect the sound in any way at reasonable levels - though I don't deliberately try to push the amps. 

    I did take my 500W 4Ω load and verify that the amp meets its power spec across the audio band - briefly.   8)  I've become quite fond of the new Crown amps - 3 year full warranty (transferable), and still designed here in Indiana.

    Sold as "New Other", appear to be "lightly used" & repaired; found a scarred screw like somebody replaced an earpiece. 100% functional!  :-+

    First impressions: SDE MUCH improved over DK2 & Rift CE. Barely noticeable, & rotated 45° like the CE, but higher res and better contrast greatly reduce perceived fuzziness compared to the CE. I am actually typing this while viewing my browser through the WMR home portal, something I could NEVER stand to do with either of my previous HMDs. Same wearability complaints as other users; lenses too close, need extra-thick forehead pad to get focal distance right & overhead strap to eliminate excess nose pressure. Still better than most FPV goggles.  :-+

    I almost bought a few months ago when the full kit was reduced to $299, but I was just overextended due to recent Ryzen 3700X build. ~$150 is, I feel, a reasonable price for "lightly used" headset only, especially considering I really want to do the Valve Knuckles controllers anyways.

    I'm still using RF4.5 - living in the past!
    It is really only for additional helicopter practice in the winter though. With the nice weather I try to get in 20-60 minutes of real flying per day with my micro heli fleet.

    Hah, I don't fly any of the micro stuff on 4.5. I often fly a 90 sized heli inside a building. It has quite a realistic feel to it and the walls come up pretty quick. I can already fly around my yard no problem with the real helicopters. The sim is more for inverted practice and some basic stunts etc.

    edit - started years ago with a Blade CP, had a trex 450 and trex 600 but didn't fly them much. Then went to micro's with the Walkera 4#3 and was a part of the brushless conversion rage(was very active on rcgroups.com). Then got out of heli's for a few years, but recently got back in with a Nano S2, Blade 130S and a Fusion 180. It helps I now have a backyard that is big enough I can fly at home.

    Same here. Mostly Genius CP, Mini CP, Axe100 (9 Eagles rebrand) and 450-500 size CCPM/FBL. Even their 500 size feel like they're mired in molasses to me; trying to do funnels and tick-tocks in RF 6-6.5 nearly broke my brain.  :palm:

    EDIT: Too bad you're all the way over by Vancouver... I'm moving to Toronto in a few weeks, and I have a couple Fusuno FUC-1071 (For Fusion 50) canopies left over from modding my 500 that need a new home. They're not worth the cost of postage, tho...

    Watching a random eevblog2 video today on modding a commercial smoke extractor while unpacking some carbon impregnated filter material for another job. eBay auction: #143251038585 Quick rummage into the fan collection and out with the shears.

    Works a treat even without a shroud, 12V 120mm fan running 7-8V  @ .2A  (for less noise and it works well enough) I have only been using a little fan on an arm over soldering jobs in the past but maybe a DIY enclosure and extractor project coming up. Laser cut ply/acrylic or 3DP for the body is the question :-//

    Decided on 12V flop it on the bench option. Laser cut ply or acrylic with three frames, two at the front to sandwich the filter (fairly stiff) between them. Offset from the fan a little so all of the surface will pull air and not be hindered by the motor as much. 150mm on the base front to back for a little more stability. Simple PWM ESC and a jack mounted back there too.

    Gave me an excuse to model a rough 120mm Fan to add to the collection too.

    Having done a LOT of fan and ductwork type stuff, NEITHER of those solutions are actually "fit for purpose". The ducted filter cube decreases the airflow velocity to the point of uselessness for fume extraction, and the ducted Hakko thing... SERIOUSLY?  :wtf: All it does is approximately double the space taken up by the thing when stowed, and EVEN WORSE space-wastage when deployed.  |O

    Just like mine with the square of filter cloth tacked to the front of a fan, bean's take has the beauty of form following function. KISS applies here in the absolute; unless the mod improves effectiveness (which the increased filter surface on bean's design DOES while also directing airflow much more usefully), it's pointless.

    I like it a lot. I'm not sure if this was your intent or not, but f you make it so the filter element applies across the curved surface, you'll decrease air resistance thanks to larger surface area while at the same time directing airflow in a manner that greatly enhances the directionality of fume extraction. Added bonus will be longer life of individual bits of filter. Well-done.  :-+

    For a silent/low noise fume filter, try using two fans in a push-pull configuration on either side of the filter.

    Counterintuitively, you might want to use a reverse cone in front of the intake to increase the speed of the airflow, i.e. a cone where the air intake is at the narrow end.  This way the speed of the airflow is much lower at the filter, and even low-noise fans can generate enough of a pressure differential or airflow through the filter.

    It might be interesting to do a three/six-fan setup, where the fans are side by side, and the air intake is a horizontal slit only a few mm tall; i.e. a triangular prism with one of the three faces facing the fan, and the opposite edge is the air intake.

    Fan in front of the filter is not a good idea with soldering smoke; it carries a large component of vaporised rosin which will quickly coat an unprotected fan with nasty stuff that looks like tobacco tar and contains lead/tin/antimony.  :scared: The little bit that gets through the charcoal filter material we're using still makes things noticeably nasty-looking after a few dozen hours usage.

    Two fans in a Vee works very well and enhances stability; it also allows you to use slower, quieter fans and still get the air velocity at the filter you need for useful fume suckage. Downside is heavier, takes up more bench space in use.

    The issue with increasing the airflow speed or adding more fans is noise so it is a balance, this nominal 3-4W fan wound back is to control the noise. Make it sound like a jet taking off and it will sit on the shelf unused, make it to bulky or clunky and you won't find room on the bench for it as an everyday item and it will also sit on a shelf unused. The small extension on top of the fan isn't just aesthetic it will help draw the air up off the bench and reduce air from above.

    Should have started a separate thread too  :palm:

    There, there bean; it's not that bad. We all know you didn't MEAN TO nerd-snipe us.  :-DD

    110% true on all counts; I learned this the hard way from my own travels down this very road.  :-+ I built several; the two best were a single 5" AC powered muffin fan and two 120mm slimline 12V ones in a Vee with a single piece of filter across the front of both of them. That one was a bit quieter so got used more, until it got knocked off the bench and one of the fans suffered 2 broken blades. The AC fan has been it for several years, and those are the very reasons why. My recommendations are:

    1) Design as simple as possible so you actually bother to build the fu**ing thing. The quick & dirty fume extractor you have on hand ALWAYS beats the one you're "gonna make" for the next three years.  :palm: Know thyself, plan thine design accordingly.  ;)

    2) Make it small & convenient so you don't mind keeping it at the back of your bench, and so you bother to pull it up to your work.  :-+

    3) Choose a  fan that's as powerful as you can tolerate the noise, or plan on the hassle of slowing it down. When in doubt, see number one above. 4-6" (100-150mm-ish) seems to be the sweet spot for both.

    4) AC-powered typically have a higher power/lower noise ratio. Some of them are little hurricanes though.  :scared: AC-powered is by default less hassle from a use & standby/storage perspective. (As long as you can have nice little plugs like we do in the US)

    Anything that comes off the fan is sucked into the filter. It’s not a helicopter blade, it’s just a fan. Even crudely shaped sheet metal jobbies still throw air in roughly the right direction.

    You can't handle the fan and NOT touch the accumulation, causing it to flake off onto yourself. Therefore comes the risk of ingestion. The filter by its nature traps the accumulation within itself, greatly reducing the amount of accidental exposure. AS IS ITS SOLE REASON FOR BEING.

    Clearly you've never actually handled such a thing or this would be obvious to you. Do it, use it yourself for a few dozen hours and come back here and tell me you think it's a good idea.  :palm:

    I like it. I'd like it more if you designed so the filter followed the curved plane; but then this would probably have to become a 3DP project, not a laser-cutting project.  ;)

    Rear fan grill isn't that critical; it's not even necessary. Even if you're daft enough to stick something tender in there, it can't hurt you; it'll just startle you as your numpties are only bouncing off the trailing edge of the fan blade.  :-//

    I have several AC fans in my collection; including one NIDEC 6-incher from the 6-Million-Dollar-Man era that sounds like a jet engine churning when it's on. I keep it for terrorizing curious kitty cats away from my work.  >:D

    For those playing along at home: Use caution when running DC fans on reduced voltage. Most computer-type axial fans use brushless motors; running too low voltage can cause premature failure as reduced airflow combines with FETs or IC driver final stages operating in or near linear mode overheat quickly due to high loading as they try to compensate.

    My usual rule of thumb is to test with a variable PSU; find the minimum startup voltage and then never run less than ~150% of that voltage. Much better solution is to choose a fan with built-in thermistor and substitute a pot; they control their own speed via PWM.  :-+

    Well in the beginning of this month I came around this deal:

    This dude was selling the item for 150$ as starting bit, with best offer available. Well I tried to offer 200$ and he accepted. Of course after that I started to feel a little cold feet, same as the common "If something seems too good to be true, it probably is too good to be true." Add 60$ for shipping and we have the final price.

    So wait time for the shipping and everything and what do you know... IT WAS.

    So together with that I had come to pick up in Hong Kong the rest of this month haul:

    So the Fluke 87V plus the iFixit Pro Kit, and a new smaller 65% Mechanical Keyboard.

    Regarding the DMM, all the fuses are OK, every function that I tried worked OK, the equipment is really in pristine new condition. Not a bad deal I must say.

    Another one to add to the 289 and the 54-II back at home.

    Two Teensy 4.0 (https://www.pjrc.com/store/teensy40.html) dev boards with NXP iMXRT1062 chip, programmed using Teensyduino in the Arduino environment: 600 MHz Cortex-M7 with 1M RAM, 2M flash (less 64K for recovery and EEPROM emulation), with 40 digital I/Os, two high-speed USB (480 Mbit/s), size 1.4" × 0.7" (35.6mm × 17.8mm).  22€ apiece from a local Finnish PJRC distributor, Mandu.  These are beasts, although the small footprint means only a subset of the chip features is exported to pins.

    Some Gowin FPGAs. Particularly, GW2AR with 8MB 3.3V DRAM and 8MB 1.8V PSRAM, in QFN88 package.
    I ordered way more than I can use, which means, if all goes correctly, I will sell some leftover dev kits (like the Trenz GN1N-9 form factor with built-in JTAG) here.
    I am marking one for myself. What exact chips are you using though?

    Not glued and no fasteners installed but first time off the Laser all the bits snapped into place and work as planned.  ;D

    Nicely stable and the rear leg could be shortened or maybe removed as the fan makes it sit on the bench well. Only made from junk ply but I have some nice hardwood veneers to maybe do a nicer MK2.

    I just bought $100 worth of 5% SMD 0805 capacitors, ranging from 10pf to 2200pf (all C0G), plus some bigger ones, and a few 2% SMT inductors between 100nF and 1nF.  I was getting tired of not having the right parts when building RF circuits.  I already have a large random assortment, but the gaps and various sizes were frustrating.  I also picked up 100ea of some various opamps.  I only *needed* a few, but the qty discount was hard to pass up.  Besides, you never know...

    I used Digikey.  These components could have been cheaper, but I wanted the good tolerances that I could trust.  IMO, still a bargain.

    A beautiful set of Probemaster DMM probes all the way from the U,S and A to here in Belgium. 30€ delivered. Postage was over a third of that, but definitely worth it for me. The contact resistance between the two probes doesn't even register on my DMM, the ones they are replacing would read 50+ mohms! Short leads so as to not clutter my bench. Very happy with my purchase!

    Good investment.

    I set up my first big SMD collection from Digikey 15+ years ago, with 0402 and 0603 in E96 resistors, E24 MLCC caps and E12 MLCC inductors. About eight or ten years ago, I added E12 wirewound RF inductors in 0402, 0603 and 0805, size depending on which of them had a reasonable Q.

    I also have a fair number of SMD power inductors collected over the years, including a few full series in E6. The problem with lab kits for power inductors is that they’re not really quite jelly bean enough to warrant stocking the plethora of specifications: you’re fighting a losing battle trying to always have all the right ones in stock.

    I still use them very regularly, and have yet to run out of a value, but I do tend to keep reels of the very common values.

    I don't do power work, just RF, so I have a good assortment of iron powder and ferrite toroid cores, so when I'm playing around I can wind the oddball inductors as needed.

    Another USB-WWAN (mini-PCIe) adapter from fleabay.  Cost about 5€, so no big risk.

    I have a Huawei ME909s-120 3G/4G/LTE modem working fine on one (Ubuntu/Mint NetworkManager/ModemManager integration works perfectly out of the box!), but the USB-miniPCIe/WWAN adapter I have has an AMS1117 LDO (5V to 3.3V at max. 800mA) that gets hotter than I'd like, and there is no way to add heatsinking to it. I'm hoping the new one has a buck converter instead.  Can't see the text on the 6-pin chip, but the presence of an inductor (and some capacitors) indicates I can have hope.. although what you get off fleabay isn't always what's on the pictures.

    I'd rather not have to make the adapter board myself: soldering the mini-PCIe connector is at the brittle edge of my current skill.  Otherwise it is very simple, just USB, a SIM card holder, mini-PCIe connector, and 5V to 3.3V regulation, and some supply bypass caps.

    Two Trenz Gowin LittleBee 9k LUT FPGA boards. Bought them for extracting FTDI firmware for my own Gowin board, but since I decided to implement JTAG with MCU, I have no use of them anymore.

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=834909;image)

    Bought for 29 Euros each plus FedEx extortion, looking for sale at $20 each, USA only, free shipping.
    It is better if you use FT2232 for JTAG though as that means native Gowin tool support. Depending on your MCU you can put both it and the FPGA in a single JTAG chain, which would allow you to debug both chip using native tools (Gowin FPGA tool for that FPGA, OpenOCD for MCU.) There are extremely cheap USB 2.0 hub chips like SL2.1A out there for combining FT2232 and MCU USB into one port.

    Do you mind providing me a copy of that FTDI firmware? I would like to build my own Gowin board too and that would be very helpful.

    1. $5 for the FTDI chip plus $1 on external oscillator (I need small size, and there's no non-MEMS oscillators that go down to 2016) is stupid for a cheap DIP-style board.
    I am using 3210 size ceramic resonators on my boards for FT232H and FT2232H. Those things have built-in load capacitors so it can be smaller than a 2016 crystal and are usually even cheaper.

    Quote from: blueskull on September 15, 2019, 04:08:29 am
    2. The Trenz boar came with empty EEPROM. Gowin programmer can talk to an empty FTDI chip (also works even without the EEPROM on SPI bus at all). So the 93C46 only serves product string customization purpose.
    If this is the case, I wonder if my Digilent JTAG/SMT2 clone would work...

    On a good day, that will work, but that's not guaranteed.

    Murate Ceralock (just used as a reference) has 0.07% initial error, 0.11% tempco and 0.07% aging, making it, for the worst case, 0.25% from rated nominal frequency.

    USB 2.0 high speed requires 500ppm (0.05%) device clock accuracy, and the FTDI chip particularly requests 50ppm. Either way, using a Ceralock is betting on sheer luck.
    So far my sample size of three worked just fine.

    Lost my old one (back when it was only Keyspan in the name, bought in 2006) and some work arrived where I needed and didn't had a serial port adapter available.

    From using with a Renishaw QC10 Ballbar System to Rollover Cisco Cables, from NSN MGW/MSS terminal connection to old measurement equipment, it never let me down.

    Nice score! I love those high power parts!!!

    I lost count of how many 50, 100W power resistors I got from the local surplus store... :palm:

    Thanks, yeah, in the age of miniaturization that everything is so damn small nowadays, I have a weird fetish  :-[ at electronic components that have real weight that I can feel.

    Well, with two 160W rheostats, I guess just for giggle, to use these twins to torture my bench PSUs.  :-DD
    I use mine for this task as well. Also, to torture test my VRLA batteries.

    The other day I bought several very large screws + nuts in the same inner diameter of the resistors. They make excellent heatsinks, especially when attached to a metal panel.

    Not exactly bought, but I built three FT232H based USB JTAG adapters in the form of USB flash drives. Information taken from Digilent website are used to approximate a Digilent JTAG/SMT2. Target connector implements ARM Cortex Debug Connector for its compact size.

    Totally. I was working at an Apple dealer in early 1999, just after the original iMac came out, which was the first computer to ditch its legacy ports in favor of USB. With USB peripherals still nascent, and people having assorted existing gear to connect, adapters were a big deal at the time. Keyspan made the only serial adapters that were reliable enough to recommend for most applications. (IIRC, they made some that were RS-422/RS-232 compatible like classic Macs’ onboard serial ports.)

    When I was looking into getting a USB-RS-232 adapter recently, I looked for Keyspan and was relieved to discover that the products are still made; at least the company that subsumed Keyspan is a reputable one!

    Does this adapter have full HW handshake?

    I am always looking for additional suppliers for these adapters, as we never know if a manufacturer will simply kill their models.

    I am currently using this Trendnet TU-S9 (https://www.trendnet.com/products/product-detail?prod=150_TU-S9) that has full HW handshake and it works really well, but I never know if/when this will last in production...

    EDIT: Now that I read that you DIY route with more attention, it will work, although I still keep what I said below.

    Prolific chipset converters are wonderful - when they work. They're one of the most problematic ones available and require close matching of the Prolific driver to your system's current service level. Widows updates are known to break Prolific drivers from time to time.

    Converters based on the FTDI chipset generally have the least number of issues. One great advantage of FTDI is that if you move the adapter to a different USB port, it generally will not change serial port numbers (but that you guys know a lot more than me).

    The Keyspan USA-19HS is the only thing I've ever been able to get to work with all of the devices I needed to use (PLCs, shipping scales, network equipment, Renishaw QC10 Ballbar System, the list goes on). This is because it has an FTDI chip and based around the TI 75LV4737A, so it has a real serial processor, as opposed to a lot of the other brands/models, which use a Prolific chip. The Prolific chips are just emulators and only work about 75% of the time.

    I used basically from the generic black smoked plastic adapter with unmarked chips to Belkin ones based in the Prolific chip. They are good for switch connections (Cisco Rollover cable and most networking).

    I would personally prefer Holtek HT42B534 over FTDI or Prolific though, as that chip implements a proper USB CDC ACM protocol stack.

    Mrs GreyWoolfe got me to a neighborhood yard sale and among other things, I got an old Craftsman Band saw with 1/3 HP motor/stand and a Craftsman 15" scroll saw for a total of $50.  Both work very well and I got extra blades for both.  The bonus was that the owner put the band saw on wheels which makes it easier to store when not in use, like I did to my table saw and miter saw.  Everything is on wheels so I can store them against the wall but easily move them out into the garage proper or the driveway for use.  Also got a self contained commercial HVLP paint sprayer, no compressor needed; a Chicago Electric rotary hammer with chisels and a bunch of hand tools/clamps in good shape.  I really thought when I went from a 26" tool chest to a 61" tool chest, it would take a long time to fill.  I apparently was being overly optimistic.  I never did realize how much stuff I had scattered around the garage that didn't fit in the old box.  It is awesome to have everything in one place, organized to make sense in my pea sized brain.  Any more stuff and I will have to take back the old tool chest from the son-in-law that lives with us that will never use it but Mrs GreyWoolfe said to give it to him when I wanted to sell it.

    Mrs GreyWoolfe got a cooler that will fit between the seats of the van, a nice heavy wooden low table for the TV/electronics in a stain she liked and a free rusty frog for one of the flower beds in front of the house.  I think she loves the frog most of all. :-DD

    That is a relatively new line of products, so AFAIK there is no brand currently using it in USB to serial adapters. It has internal EEPROM for customization which includes VID and PID, so that makes detection a bit difficult.

    Before you calibrate/adjust it, I'm curious as to what the time stamp from the previous adjustment was (to find out the drift over time). You can access it over GPIB it's in the manual somewhere...I only found out about it after I adjusted it, as you do...  :P

    A few bits and bobs... A pair of NOS Intel P8291A GPIB ICs and a few Samsung 16x2 LCD displays.

    It should yield interesting projects.


    P8291A... Maybe add an AT90USB1287 in there and you can get a USB to GPIB adapter?
    Yeah, that is my intention. Just for familiarity, I would go for a MSP430F6x or a TM4C129, though.
    You need to mind logic level compatibility though, as 8291A uses 5V while MSP430F6x and TM4C series both uses 3.3V. The whole reason of suggesting AT90USB1287 is because that is also a 5V chip, allowing use of 74HCT573 and 74HCT245 at 5V for bus latching and buffering with logic level conversion (5V NMOS to 5V CMOS.) Otherwise I would say something like STM32F103ZE or AT91SAM9260. (AT91SAM9260 can run Linux, so it is better to use that as GPIB to LXI than GPIB to USB.)

    Another interface chip I ran across is WCH CH367, a PCIe 1.0 x1 to ISA-like bus bridge chip with 5V tolerant I/O pins. You can use that to build an PCIe GPIB card if you disable its DMA features.

    It is probably a good thing to get regular medical checkups so problems can be caught before it blew up in our faces. It is also a good idea to get health insurance that covers that too.

    I have to wait for a cheap eprom eraser from ebay to arrive though, I was hoping the 405nm LED lamp I use to cure my SLA 3D printed parts would work, but nope...

    I initially just wanted the 2732's to play with modifying/translating the monitor ROM on an 80s 6809 based teaching computer I have, but got carried away :P

    I wonder if it is possible to program that D87C51 using regular SDCC...

    There was around 2001 a patched version of SDCC, indirectly promoted by Dallas Semiconductors/Maxim Integrated, for the new (well it was a "new" event in 2001) DS80C390, a fast 8051-compatible redesigned processor core able to executes 8051 instructions up to 3X faster than the original for the same crystal speed, and able to support a maximum crystal speed of 40MHz, resulting in apparent execution speeds of 100MHz.

    This monster was the core of their TiniJava(1), a Waba embedded platform coupled with a Java1 compiler and a technology called "Jump51", which was able to automatically "adapt" the JavaByteCode to the natural intel 51 code for all the critical low level sections that need some "speedup".

    It intriguing, and interesting, but it was not a success, hence they pushed their effort to SDCC, which was then "reloaded" by their marketing office for the next gen: the DS80C400 chip!


    So, around 2001-2004, as far as I remember, SDCC was able to compile for both of them  :-//


    What I mean is: we are on Gcc-v9, and GNU is going to drop the support for Itanium starting from Gcc-v11 as well as GNU dropped the 68HC11 support around Gcc v3.4.6, dunno what SDCC did with 51 after 2004.



    (1) if you want to see a pic, I have one board in my lab. It's used as weather station. The manual is about 400 pages of Java1, while the development machine is a Windows95 laptop  :o :o :o

    So expensive aroung 1994 that ... I bought a refurbished 8051 chip, pushing the firmware (Intel Basic) into a common external ROM.

    By converting "Lira" into "Euro" (x Lira = 0,16 x Euro) , but without considering money inflation, the board in the pic cost something like 120 euro. Making the PCB was very very expensive (and it doesn't have any protective paint, because too expensive), but just the MPU was 25 euro.

    This is an emergency buy really: a WD Black 2TB HDD (WD2003FZEX) replacing the dying WD Caviar Green 2TB in my main workstation. That Caviar Green was from 2011, so I am expecting it to die soon after it showed slowdowns in daily use.

    I actually bought it yesterday, and immediately after it arrived I put it into my workstation and booted into a Ubuntu Live USB to ddrescue from that dying Caviar Green into that WD Black. It just finised and exposed 13 unreliable sectors, and SMART is screaming at me for running out of replacement blocks half way down the ddrescue.

    I am booting my workstation on that WD Black now, and that dying Green is in my other machine being wiped.

    Another Swift 7 after returning the previous one. This time with two dead pixels and uneven color temperature.
    Making things worse, this unit came with dust and dandruffs in its hinge, and a fingerprint smudged trackpad, out of the box.
    Upon warranty query, thus unit was sold in May! MSFT Store, are you kidding me? Repackaging returned PCs and sell as new?

    MSFT Store is willing to return it for me, but I decided to give it a second chance and asked Acer if they can fix it. Acer basically says if it has less than 5 dead pixels, they won't fix it. Take it or return it.
    Well, return it. Thanks, but no thanks. One more brand is added to my blacklist.

    I'd like to make compromises for 1cm thickness and 1kilo weight, but this level of quality defects and such customer service deterred me. I'll put my $1299 to somewhere better.

    A mint condition vintage EPSON PX-16 portable 8088 (V20) DOS computer. The 29 year old Sanyo NiCd battery even still works, first charge on an RC charger gave totally normal behavior and full nominal capacity  :o

    I tend to look at my local auction site's "other computer systems" section every few days for interesting vintage things, and when cheap enough I'll typically put a bid without even really looking into what I'm getting. This ended up being mine for 30 bucks, and is probably the coolest vintage computer design I've seen. 4 modular bays, display could be one of 4 choices, one modular bay at the top right that could have stuff like a thermal printer or in my case a sram/eeprom card bay, bottom left is populated with a custom analog/digital IO card so it was likely used for measurement/logging purposes, memory's fully kitted out (640KB system RAM and 768Kb RAMDISK), and the most fun is that you have 3 freaking ZIF sockets for swapping around application EPROMs that just appear as standard drives in DOS.

    There was even a keyboard replacement with a keyed numpad and a backlit touchscreen LCD replacing the main area. There were floppy/HDD attachments you could stack under it, all battery powered.

    Unfortunately it seems this thing is super rare, thankfully there's one page with quite a bit of info on it, but apart from that nothing and I can't find any other units or parts for sale. Now I've seen the thing I'd love to find the floppy/HDD expansion and that sweet touch keyboard...

    NVME to PCIE X4 adapter card with lotsa holes.  8)

    Figured my NVME SSD was quite hot lying down there at the mobo, and also getting toastier as its placed near under the scorching hot GPU card, as some of the hot air flow was leaked from below the card and blowing it, decided to move it away from the GPU card, and placed at the spare and spaciously PCIEx4 slot for it to cool better.

    Aware there are so many models of this cheap NVME to PCIE X4 adapter card, but what I like about this particular model is there are so many through holes across the board, as if needed, I may put a little quite small fan there too blowing thru those holes.

    I just received the 2 x AAA powered version, not bad torque, considering its size. Very smooth, nice feel, certainly only for the small screws in aluminium and plastic scenario only I feel.
    Certainly much better than it's bigger cousins such as a cordless drills or the Bosch type electric screwdrivers for small applications.

    I think the rechargeable versions like the one you ordered are another step up in performance.

    A pair of 2 Terabyte USB sticks for $16.  Too good to be true, but at that price I had to try.  Chinese Ebay seller, less than two weeks from order to delivery.  So far a win.  Very nice apparently stainless steel cases and an acceptable ring.  Packaging re-purposed from USB cable package with sticker showing drive size.  Shows ~ 2 Terabytes capacity, with some 2 mbyte used.  Currently doing a full format and will do some other checks but other than worries about data life and such looks like real deal.  Seems to be USB 2.0 speed so not going to set the world on fire, but makes it reasonable to have an entire set of backup files on your key ring.  When the forest fire, or hurricane or tsunami or whatever hits its one less thing to worry about.

    Do you check if your cables are truly silicone (can withstand a soldering iron at 300°C/570°F), and not just overly plasticized PVC?
    The extra plasticizer tends to leech out, melding the cable with any PVC or compatible plastics given sufficient contact duration (weeks).

    The difference was that the tips on the lower one were only one outside 2mm spring wire instead of the lantern tip foil (if it's this way it's said). I didn't check the top ones, but I suppose that are lantern tip instead of spring wire.

    I think the user mnementh had some also in his collection but I can't find the topic where he shows that.

    (sorry for the bad photos, I really need to get some LED panels to provide better lighting)

    It had a rough trip ... the package looked like it was rolled down several stairs - holes in the box, etc.
    The handle took most of the damage and got a lot of the locating pins sheered off.
    Everything else looks ok.
    I've opened it up and it's very clean inside - I can't see any mark of a lot of run-time (no PCB discoloration in high-heat areas, etc).
    Now I'm pondering if I should do some preventive PSU rebuild, or if I should leave it as it is, and

    Do you know if there is any schematic available ? I've looked  over the net and I only found some partially reverse engineered ones, and GW Instek did not want to send me anything.

    From US ebay:
    "90 lbs Vintage HP Computer Circuit Boards PCB Gold Scrap Precious Metal Recovery
    Used / Gold Recovery Only / Will Be Bulk Packaged (Not Individually ESD Packaged or Wrapped)"
    Seller greenpowerparts

    This was a rescue mission. The seller didn't care that a lot of those boards are useful, some even quite rare.
    The ebay item (174036836066) got a mention on a 'classic computing' mail list. Several people on the list pointed out boards they wished they could have. One person on the list made an early bid attempting to rescue the boards, but got outbid by a gold scrapper pest. An idiotic slow bidding war between two of those scrapper pests ensued. Apparently neither of them aware of the existence of snipe bidding services.

    But I am. I also have a couple of HP 3497A data acquisition frames, and recognized a stack of those boards (rear left corner) as optically isolated DtoA modules for them. Also I'm in the process of setting up a HP 1000 computer system in a rack, and there are some serial IO cards for it.

    Anyway I won. The boards are now with a 'holding, sorting and distribution' volunteer from the CC list, located on the US East coast not so far from the seller (for minimized shipping cost.)

    Progress of this rescue is tracked here: http://everist.org/pics/pcbs/ (http://everist.org/pics/pcbs/)
    I'll be reselling some of the boards to recover some of the costs.

    Many of the boards are for the HP 6942A Multiprogrammer frame, which I don't have any of. Hence these subsequent buys:

    A pair of 2 Terabyte USB sticks for $16.  Too good to be true, but at that price I had to try.  Chinese Ebay seller, less than two weeks from order to delivery.  So far a win.  Very nice apparently stainless steel cases and an acceptable ring.  Packaging re-purposed from USB cable package with sticker showing drive size.  Shows ~ 2 Terabytes capacity, with some 2 mbyte used.  Currently doing a full format and will do some other checks but other than worries about data life and such looks like real deal.  Seems to be USB 2.0 speed so not going to set the world on fire, but makes it reasonable to have an entire set of backup files on your key ring.  When the forest fire, or hurricane or tsunami or whatever hits its one less thing to worry about. 

    (Attachment Link)
    Those are some nice key fobs, but nothing more. There is somewhere between zero and null chance that those actually have the advertised capacity, and while attempting to write beyond their true capacity may appear to succeed, that data will be lost. Use the tool thm_w and maginnovision mentioned to see what it really is. Then ask for your money back and post a bad review.

    Bear in mind that the largest USB flash drive on the market right now is a 2TB from Kingston, and it’s much, much larger than a normal one (think half a snickers bar) and costs $1000. There’s no way a random Chinese vendor could not only outperform the big guys in data density, but do so at 0.8% of the cost!

    If you want actual low cost portable backup storage, get some hard drives. A 2TB should be well under $100. The last thing you want is to think you have a backup on your keychain, when in fact you don’t.

    While we are chatting USB sticks anyone got any thoughts on an NVMe USB solution? At least you can put a known drive in it. Considering a 500 or 1TB as a portable drive rather than a backup (have NAS and external drives for that). Drive usage is more for dumping the contents of Cards with video files when out and about.

    While we are chatting USB sticks anyone got any thoughts on an NVMe USB solution?

    I've used several NVMe products from sintech (bought directly from http://eshop.sintech.cn (http://eshop.sintech.cn)), with good results.

    For example, I have a USB 3.0 / 3.1 M.2 nVME SSD external Case (PA-U31M2PCE-C) and it works well (used with an Intel 760p drive).

    My only issue with sintech is the bewildering array of products they offer, some of which seem nearly identical.  On the flip side, they do have some unique products, such as an adapter that let me put a standard NVMe drive into an older MacBook Pro (which I am using to type this) — a massive win both in terms of capacity and speed.

    To save you a bit of time, I think this is the right category:

    Little warning about those m.2 to USB adapters. A lot of them only support SATA mode, only recently (q3 2018) JMicron released the JMS583  (http://www.jmicron.com/product0201.html)controller capable of going from NVME PCIe to USB 3.1.
    Both the units linked by BravoV do not support PCIe and require SATA and those SSD's are very rare or have the wrong m.2 keying.

    Surprisingly most of the evilbay sellers are fairly clear about go no go for drive options. eBay auction: #223652718352 example one. But certainly worth mentioning for others. The bottom of the barrel ones seem to be generally SATA for about 1/2 this price.

    Check if the PSU has an overshoot at powerup/startup, I once fried a circuit with a look a like PSU that when set to 5V at powerup shot over to 6,8V spike then return to 5V, frying my board that was still connected.

    If you want to, you can try turning this into two AVR dev kits in one by flashing Hoodloader2 on the USB MCU ATmega16U2. That keeps Arduino Uno features intact, while allowing you to program both chips.

    Did you develop an issue with the old 'shitty' one  :-//

    I have a Hanba badged version of the 968A+ that had been great until a few weeks ago when the soldering iron section started triggering an error that I haven't looked at sorting. The hot air side of it has been really good to have on the bench but I don't do a lot of SMD rework with it it is more a general purpose heat gun in my case with a bit of rework.
    First of all the power was relatively low (took me long time to desolder some bigger components) temperature regulation was horrible and there was no power switch (always on).
    With older some FETs took me several minutes to desolder with new one it's few seconds. Really it's uncomparable how better is new one.

    JLC will accept it but if its anything like my board they will chop up the gerbers a bit to fit some of their rules. The 0.4mm vias probably be OK, and its e-tested anyway so end result should be good.
    There were a few rules I missed as I had not seen them specified before: hole to trace, hole to hole spacing, etc. Future orders I'm using these rules as a guide: https://github.com/ayberkozgur/jlcpcb-design-rules-stackups

    Quick check with my HP 3335A shows it's working fine down to -70dB (in fact it goes down to ~-75dB).
    A quick check with my cinesium low cost siggen (range: 34MHz to 4.3GHz) shows that it's level is frequency-dependent off in a range from -2dB to +3dB.

    Very cool, you should make a project thread once you get it up and running. I'm trying to do similar with OPA548 but I suspect its current limiting is going to be trash compared to LT1970.
    As you noted in the link you can boost the output stage with some external parts, interesting they have V+/V- pin to drive specifically, and the mosfets provide built in protection as well to clamp the output, super convenient.

    Should C5 and R13 on the output be in series instead for a snubber? Or is it some other function.

    Oh, and I bought my second power sensor cable also. In fact, I bought it first and then my brain concluded I had to buy a power meter with two channels..   :-DD

    Got my self an oscilloscope, a SDS1104X-E.   :-+
    A very nice oscilloscope with very good bang for buck!   :-+

    (I got one as a second unit and to take it with me because it's also small and lightweight but I happen to use it more often than my primary oscilloscope.)

    Yeah especially when you can hack it to 200MHz. :)

    Well, my $550 Deckel CNC from back in 2017 is finally fully fixed and rebuild to about factory specifications and nearly back in operation. ;D ;D ;D

    Should be capable of 3D milling and has universal table fitted, with a 0.001° DRO fitted in the rotation axis.

    Never mind the trigger stick, that picture was a bit tricky, with all the mess on the floor ;-)

    Price  back in 1986 was about $150'000, btw, so I paid about 0.4% original price, even better than most old test gear nowadays. Or about $0.4/kg. Rebuild was a lot of work and not exactly cheap, though.

    Nice! Yeah with CNC and other machinery the biggest and heaviest and best gear is usually cheap since little hobbieists have the room or the tens of kW sockets to connect them  :)
    Great for those who have the room and power to run it and a spouse who allows it.

    My dream in terms of CNC Machining:

    (https://mazakfiles.blob.core.windows.net/web-site/image/machine/large/1170.png)

    VARIAXIS 630-5X II T 5-Axis

    https://www.youtube.com/watch?v=CNnSxaQdXlE (https://www.youtube.com/watch?v=CNnSxaQdXlE)

    Quite impossible to have it at home, 3 Phase with at least a Power Requirement of 82.2 kVA. I installed back in 2007 2 of these in a Plastic Moulding manifold manufacturing plant in Portugal and this machine is a beast. 5 Axis simultaneous machining via EIA/ISO Programming (CAD/CAM), 3 axis simultaneous via the Mazatrol easy programming directly on the machine controller or application installed on a PC.

    The new ones are way more powerful and modern that this one, but this one was the most expensive one that I gone from the ordering to the delivery, installing and testing. All the process were coordinated by me to the customer, so it kept a soft spot on my heart.

    If I had the money and the space and nothing more to worry, I would buy one of these. Yes totally overly overkill, totally, but a pleasure to see working in 5 axis simultaneous

    https://www.youtube.com/watch?v=4VGFnEnhVv4 (https://www.youtube.com/watch?v=4VGFnEnhVv4)

    Sorry about the tacky music, all Yamazaki Mazak Promotional Videos had this bad kind of musics. I always told the Japanese that they should put a more soft and mundane music and keep only the machining sounds, but they never listen, not when I was only the worker from a Distributor not a Main Branch like UK or the US.

    The more CNC based gear you have the more you realize you NEED. Ask me how I know  :palm:

    I have been making a 'small' list of Router bits I 'need' for my 2.2kW router  :o At least the router was fairly cheap.

    Post by: Black Phoenix on October 22, 2019, 07:30:13 am
    Yes, cheap is something they weren't: The 2 of them, plus 2x 24 Tool Magazines that you would connect to the back, plus extra 2 work tables, plus options could buy you a Bugatti Veyron and still have money for some tyre replacements and maintenance cost plus some full tanks of gasoline...

    You had to have work to pay them, a lot of work, and Yudo Inc. Plastics had.

    The cheapest lathe that we had, the QTN200 2 Axes simple without any options, the basics of basics were around EU€50,000

    Like with all gear easy access to the services for $ I factor in before buying and also what an expected payback time will be. I regard my 3D printers as paid for in jobs done for $. The first toy CNC that proceeded it was a learning experience but largely a step I should have maybe avoided (cheap Ali Express 3020). The Laser cutter is well on the way to payback and the larger CNC Router is still a WIP. Locally (within 3 hours drive) no one offers this sort of service.

    Locally we have good metalworking and welding options from basic to Water, Plasma and Laser along with CNC Mills and Lathes if needed and paying some $ for those guys is far better for my mix than keeping the gear myself even though I am an OK welder. Part of why this works is I have been working on some CAD skills which was always the costly part for one offs done by others in the past.

    Buying a 30-100k+ Mill would be nice but I can buy a heap of time on someone elses if needed.

    Two pieces of equipment turned-up yesterday:

    Another F' ed-up arc welder: A Gys Spark 130.

    Unbelievable how badly designed these things are: The control PCB is attached to the power IMS through tin soldered binding posts that also serve as electrical interconnect for the high currents.
    Users bashing the welder around carelessly will tear the binding posts off the IMS, on this one the IMS is a complete wreck, I've phoned Gys who do replace them (themselves only) but won't sell me a spare. This is going to be quite challenging to repair.


    A Metrix MX52 DMM, 35€ posted. Sold as untested.
    Sure, when you can't read the display you can't really test the rest...

    The early models were known for loosing the contact fingers.
    One side...

    And the other side, they are all in place.
    They'll get a good spraying, just because a good spraying feels good.

    Cleaning ze zebras.
    Spraying the interconnect between main and display PCB with contact cleaner eases disassembly.

    Quick calibration check and readjustment where possible.
    There is no easy adjustment for the Amps, needs to be tweaked by swapping resistors.

    Right, it is smaller, but the work area is smaller, too. Sometimes I wish the work area of my machine is bigger, like the Shapeoko, but I wouldn't have much room for it. But looks like the Bantam is perfect for small PCBs.

    Yep. I do not understand why people waste their time with Chinese solder. Even "expensive" solder is still cheap, when you consider how little of it you use in a project. I doubt if I've spent much more than $100 on solder in my whole lifetime, and I still have most of it!

    Never cheap out on solder wick and flux too!, speaking of which...

    Bit of a tool haul from China, the wick was only a couple bucks and I was expecting it to be fake but I think it's the real deal.  ^-^

    I also ordered some connector pliers from Japan, the KTC AD101. I'm just sick and tired of busting my fingers unplugging connectors that haven't been touched for 25 years, so I'm hoping this tool works well. It's like 80 dollarydoos so not a cheap one!
    I've been getting by using normal needlenose pliers and slipping in a screwdriver to undo the "locks" but sometimes when you're upside down head first in a footwell trying to unplug the blower fan on an air-conditioning unit in a 1993 Toyota Supra because the heater core is leaking...yeah...I'll gladly pay $1000 for some damn pliers that work.

    The circular lock ring had been broken for while, but it was still working fine.
    Then something came loose as I was depressing the plunger and pinged across room, never found it.

    Yes the E clip breaks from the continual pounding when you press the release button.
    When mine broke I didn't have an E clip of the right size so I just twisted some 1.6mm soft steel wire into the groove and it's still there many years later.  :)

    I thought about that. But it just seems criminal to vandalize an otherwise fine-looking meter.

    And there's no screws so it's not easy to open, either. Well, anything is easy to open...

    Finally got an HP (Symmetricom) 58503B GPSDO with opt 001(VFD display). It has been fully recapped and has just over 7 years on the clock. Performing extremely well so far. It sits nicely on the 58502A distribution amplifier.

    So if you remove the sticker who says Symmetricom under it it would be HP right?

    Another thing, since i never used that equipment, what is the meaning of the sphere on the bottom right with the different colours? Position of the satellite constellation and their respective signal strength?

    Or how many different satellite signals the equipment is receiving? So that's why the up corner of the sphere is currently empty, because it can't receive?

    Sorry for the noob questions.

    Yes, it does say Hewlett Packard under the Symmetricom label(and I am very tempted to peel it off).
    The sphere in the bottom right of Lady Heather shows the signal strength(indicated by color) of the satellites over time at the antenna location. There is a hole to the north because I'm in the northern hemisphere and there are no GPS satellites over the poles. If you were below the equator you'd have the hole without signals to the south of you.
    At the time this screenshot was taken the GPS receiver is receiving and using 8 satellites, the GPS antenna is mounted outside on an antenna tower.
    Lady Heather is an amazing program that supports a vast array of GPSDO's, it is worth checking out if you have one.

    I highly recommend one if you can find it for a reasonable price. The VFD and entire front panel are from the 5313x series of frequency counters. However the entire inside front panel was sprayed with conductive shielding paint, I don't recall seeing that on the frequency counters I have taken apart.

    Post by: FrankBuss on October 31, 2019, 12:19:45 pm
    No, there is no topic here for it. I posted more details about it in a Facebook group about the upcoming Commander X16 (I think you need to be member of the group to see it)

    https://www.facebook.com/groups/CommanderX16/permalink/536904327060666/ (https://www.facebook.com/groups/CommanderX16/permalink/536904327060666/)

    This computer will probably use the YM2151 as one of two sound chips. I already implemented a software emulation for it in the Commander X16 emulator, thought it would be fun to compare it with the real chip. I probably will only populate the 10 boards I have and give it away to friends (I got already 2 requests), and sell the rest, I don't plan to build something big with it. It has an integrated SAMD21, which can be programmed over USB with the Arduino IDE, and which was another reason for me to build it, to have a reusable SAMD21 circuit component with USB and Arduino for other projects, and it can be connected to the expansion port of a Commodore 64 and used from there. But probably not worth the trouble to build more of it, with the uncertainty to get enough working YM2151 chips for it.

    Yes, nice indeed.
    Be warned though, I used one at work - it might be hydraulic but it still took lots of effort to crimp and get it to release !
    Just after I was all red in the face and panting, my colleague got out the battery powered hand tool for crimping and showed me how easy it was

    I have a Izumi 12t battery powered hydraulic Crimper and it is so much better than the hand pumped ones. I use it quite often, although not daily as I used to in my previous job. The biggest problem with the hand pumped ones is keeping it steady while pumping if the cable is already in an enclosure / vehicle.

    Huh, bought another GPSDO.

    Currently under test:
    - GPSDO UCCM module Trimble 57963-D
    - GPSDO UCCM-LP module Samsung with STP 2878LF OCXO
    - BGTBL7 2017-12-17 GPSDO with display

    They're working ok but I'd like to improve my GPSDO to the highest level possible using low cost/affordable* measures.

    I have been fiddling around trying to replace the fitted OCXO with another, more stable OCXO (Morion MV89A) but failed, because the parameters of the feedback loop can't be changed with these GPSDOs -but that's necessary for them to work correctly.   |O

    As the consequence I bought a Trimble Thunderbird GPSDO module today because it's known to be adjustable in this regard.   :-/O
    Time nuttery time ahead!  :)

    I like the "The Final Cut". "Ummagumma" is the one I don't like so much and "The Endless River" is the album I lack in my collection.
    Instead of "The Final Cut" I was actually looking for "Atom Heart Mother", but it was not listed in the promotion "take 3 pay only 2".

    I got a set of cheap router bits a few weeks ago. Work nicely on softwood and MDF but on hardwood you would want to peddle gently. The plan is over time to swap them as needed for quality ones to go with the CNC router but they run $30-200 AUD each  :o

    Cheapy set I got eBay auction: #303319443363 Dimensions across the cutters is questionable when measured with calipers.

    Gonna mess about with trying to wind wire on some different inductor rings I got from somewhere I can't remember. I want to  see how ring size and colour and wire size and amount of turns affect the end measurements. I got a good mixture of different colours and size rings and I've got some more sizes of wire coming too so we'll see.

    I've been meaning to do this for ages but never got round to it....   :)

    Yeah, many tools are OK on softwood & "die the death" when exposed to hardwood.

    I remember many years ago, having a popular woodworking book that advocated making the  mating cuts in floor joists & the wall timber framing with a jigsaw.

    Seemed like a great idea, till the jigsaw blade touched the jarrah---- clang! goodbye blade!
    Jarrah is great wood, till you come to cut it--- "shame you can't weld it!"

    Seriously, I've found that manual tools are often quicker & easier with jarrah & other hardwoods.

    There are some godawful electric tools out there, like the much advertised "Renovator" vibratory saw.
    Maybe the "Wicked Witch" could use it to renovate her gingerbread house, but it was useless for anything I tried it on!

    Jarrah is Easy just hit it with a little Laser Beam ;) Soldering Fume Extractor prototype in pic.

    If i was into making furniture or hardwood then I wouldn't have got a starter set. My theory is if I needed to do a short bit with a particular profile then I now have a spread of bits. I already have some 1/2" shanked good bits for the CNC so I will slowly add to that as I need or can afford it. Makita Cordless Trimmer is the weapon for the cheapy bits.

    I have tweaked the crossflow over the Laser bed from what used to be fairly ordinary it now draws across the front of the bed and the only other gap is at the rear fan. The fan at the rear does a good job of smoking up the neighbors backyard via an external duct >:D

    Just ran into this myself.  Granddaughter broke the bottom step of the bunk bed.  I had a small tabletop in the garage suitable to make a new step.  Decided to make the cuts with my jig saw.  Not sure what the wood was but the blade struggled to cut, bounced on initial cut and was a pain with the cuts being less than stellar.  Stepdaughter didn't care, the step was replaced.  Of course, the idiot behind the jig saw completely ignored the band saw that would have been more than suitable to do the job.  :palm:  The saw was a recent purchase at a yard sale and had not even been used in anger yet outside of turning it on to make sure it worked.  Lesson learned.

    I received my Anritsu MF57A 600Mhz frequency counter complete with operation and service manual.  This was a nostalgic purchase because it was one of the bits of kit on the bench when i started in telecommunications that i never played with because the learning curve was high and I didn’t have the opportunity to get my grubby fingers into it.

    Went to the Hardware shop with actual $ in my wallet. Needed to supplement what should have been enough with a chunk of plastic $ :palm:

    WEA........... Clamps are now being used on the wallet for a while at least but maybe I should add some of the 4L of PVA to help balance the non budget......

    Do you check if your cables are truly silicone (can withstand a soldering iron at 300°C/570°F), and not just overly plasticized PVC?
    The extra plasticizer tends to leech out, melding the cable with any PVC or compatible plastics given sufficient contact duration (weeks).

    Regarding this, Today I gone again to the Electronic supermarkets and they had one there already cut for testing. Yes they are not truly silicone, they started to rip parts with a hot soldering iron. Also no indication off the wire gauge plus writings on it, but by the cross section is way smaller. Insulation was 12AWG (4.5mm) cooper inside equivalent to a 16AWG (1.29mm).

    I will probably buy the cable separately and the banana plugs and do myself my extensions.

    Ok, I didn't purchase it, but my Brother found this laying in the dirt in an old barn of his, no other TE related stuff just this.  It's an Eico 427 in horrible shape, I have no plans for it but thought I'd post here and see if anybody needs a knob/etc, tube might still be in-tact.  Reasonably sure about 10000000000000000000000 generations of mice have occupied it over the decades.

    Otherwise off to the trash it goes.

    I've had a fair bit of other stuff by BlitzWolf in the past and although it isn't "high end" I've always found their stuff to be decent quality and it usually meets or exceeds quoted specs by them.

    Their cables and other stuff seems to be of decent quality for what they are too.

    Just got my new Probe Master leads.

    I bought the automotive kit. Not much to it, just the leads, two banana jacks, a a pair of large clips.

    I bought the 48" leads, but I want to get the next size up, 60".
    I'll use 48" for home.

    I love how affordable these probes are! And the gold plating is so gorgeous!

    Bought a couple of cheap over-the-top cheesy SKMEI watches off eBay for the occasional outing (~$16 US a piece). I wonder how long they will last and if they are any good? I didn't buy them to keep the time, it is just the look. They are gigantic and probably be too huge for my tiny wrists. Perhaps a tear down will be in order in the future to see what electronics and mechanisms drive these things. They look different than anything else I own so it was to have something of a different style than my norm... other than that I expect them to be worth about as much as I paid for them, which was little.  :-DD  My kids can then have fun with them. Shipping date expected as late as Feb 2020! I guess that's what you get for "free shipping".

    How far do they have to ship?


    Using free shipping on my Probe Masters took 5 days, despite the fact the place they shipped from is a 6 hour drive from where I live.

    That is the "estimated" shipping range for the watches: Wed, Dec 11 - Tue, Feb 04.

    So as late as Feb 2020, but could come before Christmas!  :-+

    I ordered a couple other things and they gave me a better range: Thu, Dec 12 - Tue, Dec 24.
     
    So it maybe is just to cover their butts in case it gets delayed. I've ordered stuff before that had 2-3 month shipping times and it came way sooner.

    I don't know how China ships these free packages, but perhaps this is because they work on filling up a shipping container and it takes them a few weeks just to pack up the container full with all the stuff going to my particular area. Then it could take another few weeks to transit across the ocean on a large container ship, and then another few weeks after it lands to get processed through the local mail system. At least that's how I fantasize it is done. But who knows? Anyone venture a guess?

    I think the postie gets extra in his pay cheque too if he kicks it all the way to your home from the sorting office.
    I'm also sure the reason they pack the item is so the postie doesn't get sore feet kicking it....

    I have owned RTCW since way back when and it will need a little modding to get working on my new system but I paid the pittance for an online version as I don't own a CD drive in a box and added in The New order via humble bundle 70% off for about $5USD after credits. $ well spent.

    RTCW was a sort of weird game. I haven't even tried to play it in years even though I have it and a PC which can run the original version natively. The New Order is a lot of fun but I think The New Colossus was better.

    Got RTCW running fine now as a windowed screen at 1600x1200 on my 1440P monitor without any other mod packs installed on my Ryzen 3700X and 5700XT system so I think I will stick to that rather than install third party hacks and forgo the full screen.

    Scary but I even remember where most of the secrets are on the first few Levels after many years of not playing it :o

    That's pretty good. I think I played through that game once or twice(the multiplayer was never my thing), but then it was pretty much just diablo 2 for a couple of years. The first 2 Dooms and Quakes, and the original Wolfenstein(PC) I remember every secret and level though. Now I feel like I have to play through RTCW again just to remember it!

    Hey, you have two 1972. Want to sell one?

    And btw, do you collect HP Application Notes too? I've returned to that pursuit, after yet another painful reminder that many people are destroying these wonderful old documents, in the process of 'scanning' them. Cutting bindings off, to feed through auto-feed scanners, etc. Invariably making really crap quality scans, so really just vandalizing the paper originals for no real result.

    I'm worried that by the time my finances improve (few more years maybe), many of the App Notes will have vanishingly few intact copies still existing. A pox on people who destroy rare historic print originals to scan them.

    Yeah, I use them for 'research', too.  Scary how costly research is, isn't it?

    I haven't started down the app note rabbit hole so far, but fear I'm apt to now.

    Unfortunately, the second '72 wouldn't be worth the postage.  I got it from Tucker Electronics before they shut down, and discovered that many of the instrument photos had been excised, scrap-book style, so it looked like Swiss cheese inside.  I contacted them about it, and he was very apologetic and said that catalog must have been used in the old days when they used to make up information sheets for their gear - apparently before desktop publishing was mainstream they'd literally cut and paste to make their master datasheets, and had gotten put in the wrong pile after its 'operation'.  Fortunately, they had another good copy, which he then sent.

    I had a lot more luck with Panasonic Evolta, after had both Duracell and Energizer batteries leak and damaged equipments that I own, one of them being the Fluke 54II (It had Duracell Procell on them). The 289 was catch at the same time before biggest damage was made (Energizer Normal Alkaline), Since they were starting to get "wet" close to the negative.

    After that I bought a pack of 12 Panasonic Evolta that are still great, 6 years after. The other ones (Duracell and Energizer) were damaged in less that 2.

    Here in China my wife uses GP Alkaline everywhere. I'm still trying to find an old equipment with leaking batteries on it, from the AC remotes to the wall clock. My 87V currently have their Energizer 9V that came with removed from inside it, until I find a suitable replacement.

    Since I always read great about the Eneloop's, so I taken the plunge, being the AAAs for my Texas Instruments TI89 Titanium and the AAs for some heath equipment (Blood Pressure Machine, Milk Breast Pump, etc) while I'm probably going to buy some GP rechargeable to the rest of stuff that doesn't need an high energy demand, specially my baby toys that I may buy in the future and other minute things.

    I remember when I was a kid throwing away tons of depleted AAs because of my Game Boy Classic (Pokemon was the cause  ;D).

    Let me know what you think of it once you’ve had a chance to use it for a while. I was just looking for a new charger and that was one model I was intrigued by.

    FYI, they’re a great deal cheaper if you buy them at IKEA, where they’re white-labeled under the LADDA name. (The white high-capacity LADDA are eneloops. The low-capacity, but lower self-discharge brown cells are of unknown OEM.)

    I will for sure. What I can say for now is that as options it have a low charge mode for less than 750mAh batteries and the screen is well visible at most of the angles, with backlight that can be turn off.

    The original Eneloop Batteries were designed and developed by a battery factory in Takasaki, Japan. That factory and the Eneloop brand were both owned by Sanyo, but in 2009 things changed. Panasonic bought the Eneloop brand, while Fujitsu, as part of its FDK subsidiary, owned the factory and all the IP associated with the manufacture of LSD batteries

    FDK is an OEM manufacturer for other brands, Like Amazon, Fujitsu, Panasonic, and IKEA. So there is a chance that batteries from the same high-capacity to be exacty the same quality.

    I got the Opus C3100 charger for charging my 18650's. I find it ok but haven't had another to compare it against.

    Yeah! The white high-capacity LADDA batteries are made in Japan, and with FDK supposedly being the only Japanese manufacturer of such cells, people have concluded that those LADDA must be eneloops, essentially.

    The brown low-capacity ones are made in China IIRC, so who knows what OEM they are. But they seem to work fine. (They recommend them for low-current devices like remote controls, where I guess the high capacity cells self discharge faster.) IKEA seems to be quite good at selecting battery OEMs: I’ve also been a fan of IKEA’s alkaline batteries for years. They work great, I’ve never had one leak, and they’re insanely cheap.

    I bought 15 a couple of days ago. A result of searching (unsuccessfully) for HP App notes: 201-4, -5, -6, -7, -8.
    If anyone reading this happens to have/find those in original paper form, please PM me.
    Edit to add: Looks like I have now secured 201-6 and 201-8.

    That's an amusing story, and certainly worth keeping the cut-up copy as a conversation piece.
    You should expand that note,  print, date and sign it, and stick it into the cut-up copy. Makes it more of a historical item for posterity.

    McBryce.

    I think the postie gets extra in his pay cheque too if he kicks it all the way to your home from the sorting office.
    I'm also sure the reason they pack the item is so the postie doesn't get sore feet kicking it....

    There was me thinking it was to protect the item from being damaged... what a dumbass!  :-+

    lol, I used to work for Australia Post IT, the sorting machines are the culprits, the big football stadium sized sorting machines move the parcels around at 2.5m/s - anything not packed properly doesn’t stand a chance.

    I recently bought a second hand router via eBay and the idiot seller just threw it loose into a non padded satchel. Needless to say it arrived minus 2 antenna and beat to hell. I made the idiot refund me and pay return postage.

    The museum is having a swap meet next week, but I managed to raid some stuff early.  Got my paws on a Tek 7603 with 7A18 vertical and 7B53A sweep plug ins, along with a pair of 7A26 verticals and a 7B50 sweep to go along with it.  Also snagged a non-working and somewhat dirty 465B and unearthed a Weston 1240 DMM.  Oh, and an old tank radio.  Not a bad haul for $40 in my opinion.

    FYI, they’re a great deal cheaper if you buy them at IKEA, where they’re white-labeled under the LADDA name. (The white high-capacity LADDA are eneloops. The low-capacity, but lower self-discharge brown cells are of unknown OEM.)

    I bought a Halo power bank for Mrs GreyWoolfe from QVC.  Yeah, I know.  She liked it and wanted it.  With it being on sale and saving $15 for being new to QVC, it was only $23.  Worth it if it works as it should and makes her happy.  Happy wife, happy life.

    My MiniAmp v2 board arrived from JLCPCB today. I have fixed some layout problem and the power down pop, added a headphone jack, and upgraded the onboard DC-DC converter. This is also my first board using primarily 0805 SMT passives. (my other projects uses 0603.)

    MX Keys keyboard and MX Master 3 mouse.
    I needed something to switch easily between computers, but without the BT headache. So I got 2 unifying receivers for two devices and it's just a button press, independently for both devices (also one of the constraints I had). The thing is I bring work home, and company policies are pretty restrictive, but this is just plug and play. and I can work with two computers at the same time.
    Although I was skeptical about the keyboard, after a short use I find the experience great. Minus is that it's partially customizable and settings not stored on board. Mouse looked great on the first touch, but somehow it has a strange center of mass, so far hadn't got used to it, definitely not a choice for games. A lot better cheaper options for that. OTOH pretty customizable for the mouse. Materials great on both devices...
    The extra space on the bench and no wires make it worth.

    I have a similar set here: a K375s and a M720. Both devices came with a Unifying dongle each for two of my devices, and I bought a third dongle for the third channel. (Both K375s and M720 are three-channel devices, and my Dell P2415Q monitor has three inputs, so this means I get effectively a three-way KVM using just one set of keyboard, mouse and monitor.)

    Oh yeah, I almost forgot, I got an MX Vertical a week ago. We shall see whether it’s any better for my hand than the Performance MX (ancestor of MX Master series) I’ve been using. What I can say already is that I miss the freewheeling scroll wheel. :/

    Did you consider MX Ergo (trackball)? It's weird but two of my colleagues that use it say it's easy to get use to it and since you aren't doing any pushing gives you some flexibility on how you position your hand on it.
    Although I haven't played games in a long long time, FPS (CS) got me hooked on precise/balanced gaming mouses and snappy moves, I'm missing clicks a lot with this one, and Ergo seems like a mission impossible for me. Master 3 has (at least they say) a new version of the wheel, and it's damn fan to scroll, but using a wheel as a middle click is a bit clumsy.

    There doesn't seem to be much about any of them posted online, but I did find a Schlumberger 1240 that appears to be identical looking externally other than saying 'Schlumberger' on the filter instead of 'Weston'.  The page on Radiomuseum indicates 1971 as the date for it, but I'm not certain that's the first year it came out.

    https://www.radiomuseum.org/r/schlumberg_digital_multimeter_1240.html (https://www.radiomuseum.org/r/schlumberg_digital_multimeter_1240.html)

    I can't find anything 'official' about the Weston, but for what it's worth I opened it up and the semiconductors have late 1969/early 1970 date codes.  They look to be siblings, but which came first is anybody's guess at this point.  Markings on the Weston indicate it was made in the US and shows Weston as being in Newark, NJ.

    Seems like every single day lately I'm painfully reminded of how much better the 2nd hand test gear situation is in the USA, compared to Australia. Ditto for old tech documents.

    Now you should have to pay many hundreds of dollars in shipping fees to actually get your hands on those goodies. If they survive the international carrier's random smashing process.

    Oh well. I've had a few nice acquisitions lately.  Freebees:

    Unfortunately my right thumb is by far my most painful appendage, so a thumb trackball like the MX Ergo would literally be my nightmare input device. (I even unenrolled my thumb from Touch ID on my iPhone to discourage myself from absentmindedly typing with that thumb, lest it get worse.)

    So on my desktop, I use a mouse on the right and a trackpad on the left (retraining my left hand to trackpad was surprisingly easy). I try to remember to turn off the mouse so as to rely more on the trackpad.

    I use Anker vertical mice myself.  Bought one to try and liked it.  Also bought one for Mrs Greywoolfe but her hand is too small.  This mouse is not for people who have small or medium hands.  I have large hands and it fits me just fine.    They are on my personal and company computers.  Along with MS natural 4000 keyboards and commercial grade adjustable keyboard/mouse trays, the setup is much easier on my arthritic hands.  I have no plans to switch back to regular mice.

    I presume you mean you programmed whatever thing talked to these? They are purely I/O ports. I don't yet know what's on that 15 pin connector but I'm guessing something serial and dumb. It loops through the bases, but I don't know how many it can daisy chain.
    Hopefully nothing too insanely proprietary.

    Let me know what you think of it once you’ve had a chance to use it for a while. I was just looking for a new charger and that was one model I was intrigued by.

    Ok I have some updates for you.

    First I ask you to read this review, since it's the most complete I found with a lot of testing that currently I can't and don't have enough equipment at my disposal to evaluate so deeply:

    https://lygte-info.dk/review/Review%20Charger%20Nitecore%20Digicharger%20D4%20UK.html

    My opinion: If you have the need for a charger only for all kind of NiCd, NiMH, LifePo4, LiMn and LiCoO2 then this is the right one, since all the modes he uses can charge all this batteries. If you only need for NiCd and NiMH look elsewhere, the money asked for this one you can get the GP Battery GP PowerBank Universal PB19 that charges AA, AAA, C, D and PP3 and still save some money. I didn't also had the other types it charges for testing.

    The slow charge you can activate when charging batteries lower that 750mAh is great to keep the life out of them, without warming too much the batteries. Although you have to select each battery and activate said mode on 1 per 1 basis, it doesn't have an option to cycle to all batteries and then select said mode (the selector only cycles between 1,2,3 and 4, it should be 1,2,3,4,All).

    It detects batteries in reverse polarity, their charging and the main test also indicates when a battery is damaged and need to be throw away. Unfortunately it doesn't support a discharge more or "recycle mode" to charge a battery, discharge and charge again. In terms of time I can't give a expected time to charge 4 batteries because of that reason and that the batteries that I have currently have charge on them (Panasonic Eneloop Pro AAA and Panasonic Rechargable 2000mAh. Both Eneloops white I said I bought were fake. All Panasonic rechargeable batteries come in the plastic blister in pairs, with 2 also surrounded in plastic. Mine come separated, one by one and the writing were not consistent and with errors on printing. So I bought in HK the real ones, and since they didn't had normal Eneloops I had to choose other models). Although I put the ones I bought to charge, and 4 AAAs taken around 1:30 to charge from 3 almost 4 segments to full, at 375mAh each. The AAs were full charge.

    It also doesn't detect non rechargeable batteries so care should be taken when putting batteries that you don't know the origin, it will try to charge everything you put there. You should also take care when charging AAAs, since they are smaller if not inserted correctly they may slide out since their diameter are smaller than the slot were they sit, and with that it have a gap on the sides, were moving the charger or tilting it will make them jump from their spot and stop charging. Type C batteries are only supported in the middle slots, for what I see. the side ones have higher walls that doesn't let them sit well.

    The screen is always showing the battery current charge level, time, voltage and mA, cycling through each 2 sec. The said screen is also very good in terms of visibility, black with white segments and the backlight is always on, although you can turn it off by pressing a button.

    Hope it answers yours questions and if you need anything more just ask.

    Just got a package with 2 BOC-Edwards XTC255H turbo pumps, with controllers, pirani gauge, and a ton of vacuum KF fittings!
    Scrounged from a scrapped triple-quad mass spectrometer! Not bad for 60 €  ;D
    Nice what are you going to do with them?

    I'm donating the quadrupole and one turbo to my university's mass spectrometry lab (Ho Ho Ho!).

    For the rest, I have many plans! DIY mass spectrometry, physical vapor deposition, DIY electron valves, and so on! Having a proper ultrahigh vacuum system opens so many doors.

    Not shown is also a mysterious device I THINK is an ion pump, which would give me around 2 orders of magnitude higher vacuum than even the turbo produces.

    I'm very envious. Working turbos _with_ matching controllers are almost impossible to come by.
    Something you should do RIGHT NOW - cover the turbo inlet ports with about 4 layers of clean alfoil, wrapping it tight around the edges. Just leaving those ports open to settling dust from the air is a disaster. Oh, and DON'T give in to temptation and touch the blades with a finger to 'see if they spin' or whatever. Skin grease, you'll never achieve good vacuum, without giving the pump a serious cleaning with solvents in a vapor phase tank.

    Also, what? You are donating one to your university? Why? They have way more money than you. Are those two turbos near identical? You really should keep both, one as a spare. Or are you not aware that it's very easy to kill a turbo with silly sequencing mistakes as you get familiar with vacuum system operation?  Google turbo blade crash images, if you didn't know.

    Ditto the quadrupole. If it's just a bare unit sans the entire system it came from, there is near zero chance anyone is ever going to actually use it for anything.

    Re the first one, mass spectrometry, your chances are better if you set up a watch on your uni's chemistry lab dumpsters. Universities tend to just throw those incredibly expensive systems out and buy new ones regularly. Like the HP 5973 mass selective detector I have. Put out in the rain at Monash uni Chem Dept. when they upgraded. Unfortunately minus the controlling PC, software and HP-IB card, and matching gas chromatography unit, which I was told were simply discarded at different times, dammit. My chances of ever getting it going are very slim.

    Post by: BravoV on December 04, 2019, 02:10:01 am
    I've been exploited by local seller that knows I have a weak heart on quality rare electronic component, of course with cheap priced.  :P Yelled at me... "Want to see me to salvage it's copper savagely ?  :'( Make a decision now ! ..."

    Here we go, yet another isolation transformer 220V to 220V, and my 1st one is even gathering dust.  :palm:

    Still not sure what to used for, as for test & measurement, I already have HV isolated diff.probe and isolated handheld scope.  :-//

    Shot with Fluke 189 for size comparison.

    Ok, to be fair, one of the MS department guys is a friend of mine, and he's restoring the exact triple-quad instrument these parts are from, so the assemblies that are specific to that instrument would be a shame to butcher for generic-ish components. I don't really have any use for an octapole collision cell, aside from having it as a cool piece of super well engineered tech.

    Turbos are safe, i only took the protection off for the photoshoot. And I'm not spinning it up before I've made a nice 19" rack controller box for it, with gauges for rough vacuum, high vacuum, motor speed and temp. Furthermore, the Pirani gauge i got with it has a set point which will be wired to the kill-switch of the turbo, so if the roughing pump starts to limp, it'll pull the plug on the turbo.

    Granted, this might not save the turbo, as it takes it almost 30 mins to spin down from 80.000 RPM to standstill, but it's the best that can be done.

    This will also eliminate the risk from accidentally turning on the turbo before the rotary vane pump.



    And with regards to DIY MS: Ben fron the Applied Science youtube channel just built a super simple one. I think it could be done one step better with a linear quadrupole (and quad driver controllers are pretty cheap on the ebay)

    And yeah, you caught the exact snag with adopting an existing system: very expensive software. I'm still battling with my 30 year old HPLC's win95 drivers.

    Ikea for sure, don't know about Xiaomi, but AFAIK that capacity/spec batteries are made in just one factory.

    Dozens of them were auctioned earlier this year after the bankruptcy of Mapper.
    But I had no idea what to do with them so passed on them. Dont even know how to do metal disposition etc.
    Is that something you can do at home ? Dont you need a cleanroom? What will you do with it?  :-//

    However I bought a Edwards XDS35i  industrial vacuum pump that already had 26000 hrs on it (found out later after pickup) still would go just over $900. New thry are in the $20k i believe. A simple gasket replacement set will set me back $700 so I hope it will last me a few years. It works but also had no caps on the input output.
    I have to find some matching hose and adapters and a decent prefilter is necessary i believe. The thing can only go from room pressure to 10mbar five times an hour but can run all day long at 10 mbar , weird devices  :)
    I want to use that one for a diy p&p machine and vacuum table for my cnc mill, I know way overkill but fun.

     The flanges on it are called KFXX flanges, xx being dimensions of tubing in mm. You can get flange to hose barb adapters dirt cheap on the ebay! 
    I wouldn't worry about filters for low-crit applications like this.

    Metal deposition is certainly possible without a clean room!
    Question is just how decent results are. Worst case, making a "clean room bag" glove box full of dry nitrogen coupled to the vacuum chamber inlet as a clean prepping/cleaning zone might do the trick! I'll def. Try.

    It seems pretty solid. I cloned the drive to an SSD and made sure it worked then I stripped it down. Cleaned everything and it's nearly like new but I'm still waiting on the bluetooth module and flash cache module so it's still in pieces. The fan runs all the time the nvidia chip has underfill and a heat pipe on it with thermal compound so I think it'll be ok.

    Hi, I recognize the seller's pictures (F1*****), I bought from him once.
    The shipping is always high, but the parcels are rock solid and the equipment is very well protected.
    Is that the seller with the stupid prices for ancient crap? They refused my overly enthusiastic offer once, four months later they were still trying to push it for significantly less. Luckily I had come to my senses and scored better kit for less.

    Just got these two Symmetricom 58502A.
    Perfect condition.
    Will be used with GPSO primary and rubidium clock secondary to distribute the 10MHz ref to the bench instruments.

    I've bought from him at least once before, the pricing is a little random, but once in a while he does have some decent deals.
    Anyway we don't have that much choice over here.
    His packing is done very professionally with injected polyurethane foam.

    I was looking at buying a Triton or Contractors Table saw but then did some more research and youtube watching. Much safer for the fingers and it became clear keeping the sheet locked down and moving the saw makes more sense without in and out feed tables/horses taking up a heap of floor space.

    The plunge feature makes it a lot safer for sure - circular saws always made me nervous with their Mickey-mouse guards that seemed to get in the way more than guard.  This type is great -plunge, cut, release and the blade retracts and you can put the saw down on a flat surface and it just sits without wobbling or tipping.

    Will do. Thanks for the heads-up.
    Opened both as I was removing the usual stickers and glue plague.
    Today I undid the PSU on both and the caps looked OK (no bulge or leaks) and they tested OK for value ( one is about 10% low) and ESR OK for all.

    Will keep an eye out for this as I order replacements from Mouser.

    Are the caps going bad a known issue for the Symmetricoms or good prctice in general for older caps?

    The specific issue is the MAP55-4001 that is often used in the 58502/58503. The worse cap is a 10-33 uF located right beside a transistor on the input side. On later revs of the supply they remote the capacitor with flying leads. When that one starts to go bad it will take other components with it. It is a pretty quick job to swap all the caps, well worth it for something that runs 24/7 and that you want a clean signal from.

    The one I have for my son has a very slight tool mark near the barrel.  Outside of that, it looks good and functions perfectly.  The finish was fine and no distortion.  I find it odd that you had a problem.  I thought that they were CNC machined on a mill.  Nice to know he made it right quickly.

    The sticker outside the box have the manufacturing date. Plus you can check the firmware in the DMM:

    From turned off:
    - Press and Hold: AutoHOLD
    - Switch to DC Voltage on the selector and the screen will show the firmware revision - Last one is v3.03

    Since the serial no is also greater than 19470148, it will have new generation LCD display and GSM fix installed. - https://www.eevblog.com/forum/testgear/fluke-87v-screen-goes-crazy-with-wifi-cell-phone-signals/ (https://www.eevblog.com/forum/testgear/fluke-87v-screen-goes-crazy-with-wifi-cell-phone-signals/)

    Quite interesting; I have a 87V serial number 1056xxxx (firmware 3.01) and did the cellphone test around it in various ways. No interference either when calling or when transferring data via 2.4GHz Wi-Fi.
    I wonder if it was inherent to the frequencies used by 2/2.5G GSM and not the 4G/LTE used by modern smartphones.

    Just opened both and the PSU is the MAP55-4003. They both have the remote cap as you described. It is a 47uF at 35V. Both measured about 52uF with an ESR of slightly below 1 ohm.
    Just added these two to my Mouser order list, just in case.

    Cheers and thanks.

    Many thanks, it's v3.00, so fairly recent I think.  I had seen the GSM issue, which concerned me initially but I realised that this one must be a later version than those affected by that problem.

    I might end up doing that also, I wouldn't mind having an original at all.  Have to recover from Christmas spending first.  I just did a quick look, interesting that they are all listed in Canada.  I hope mine arrives with no issue.  I don't like being the one to piss and moan, even if it is necessary.

    Nice score!  Mine needed a tantalum cap in one of the modules.  That thing's a backbreaker, huh?

    Good grief yes.  I think the two person lift sticker may have actually been factory applied.  When I built my present work area, I put some gouges into one of the work surfaces wrestling it into place by myself because I nobody was available to help me with it and I pulled some muscles pretty badly doing it to the point I was beginning to worry if I'd given myself a hernia but thankfully not.

    Back in the day, where I worked, we travelled all over the State doing routine testing on TV sites.
    Amongst the pile of equipment we took with us was a R&S "Polyskop SWOB" (one of several at the Depot), which was seriously heavy & had a similar sticker.

    We would get a courier service to take things to airfreight & would travel on the  same plane.
    On several occasions,the Polyskop would arrive at the other end inoperative & making ominous rattling noises.

    It turned out someone, either in the airline ground crew, or the couriers would read the sticker, grunt "bloody wimps" & pick it up by themselves.
    You could do so, but putting it down, they would invariably, drop it the last 150mm (6"), causing the heavy bits inside to break loose from their mountings & fall through the fragile bits!

    So the lesson for equipment manufacturers, then, would be to keep delicate products out of the “danger zone” of weight that is too heavy to be carefully lifted by hand, but too light to unambiguously require assistance from another person or equipment. Perhaps load it down with another 10-15kg of steel plates, or make the housing more robust by that amount! :p

    The housing of the Polyskop was very robust.
    Perhaps the mounting of the big bits should have been better .
    Or maybe morons shouldn't ignore warning stickers! ;D

    It happens in the best of families, though.
    We received two 5kW Broadcast transmitters from Harris, where  one was, luckily, OK, but in the other one, a large power transformer had broken loose & rampaged through the thing smashing the more fragile parts.

    Such things are normally sent with the heavy bits separately packaged, but for some reason, Harris decided to diverge from their usual practice, & sent the complete made up units. :palm:

    It was a good thing only one unit was damaged, as we had one good one to compare with as we painstakingly rebuilt the bad one. |O

    Had it been NEC, they would have sent one immediately, but Harris would have spent the next six months bitching & scratching their bums!

    The best service we ever had like that, was back in 1968, when we had a transmitter fire at a remote Northwest town, which killed both transmitters.
    AWA put a new transmitter on a chartered plane & flew it straight there.
    (It turned out the fire wasn't the fault of their Tx, but it was a good example of customer service)

    One original Tx looked like a huge version of a burnt tin can from a campfire, but we rewired the other, & it was still in service 20 years later.

    I found the caveat in the deal,
    the calibration just expired.

    Which is fine for my bench.
    I doubt my old GW Instek GOS-635G
    was ever calibrated outside the factory
    and it has served me well for the past
    couple years ( bought used from someone
    of whom I believed obtained it from
    someone else who bought surplus from
    when ITT Tech closed up shop ).

    It must have gotten lost and been
    laying around for 12 or 15 months
    and they just wanted to clear it out.

    If anyone is in the market for a great deal on a Rigol 1054z,
    uCenter's web store was showing they still have a handful
    or two scattered around the USA and last I checked they
    were down to 184.31.
       ( store pick up only -- 1@Duluth-GA, 2@Rockville-MD, 2@Westbury-NY,
          1@Brooklyn-NY, and 3@Yonkers-NY )
    By the time they sell the last one, someone is going to walk away
    with a 1054z for something entirely ridiculous, like $35.

    Cheers.

    (Attachment Link)

    Good story all around, a little sad to be sincere, if you only see the Anime (good adaptation from the base source, not very common). Although the adaptation is only the first part of the trilogy. You had to play the White Album 2: Extended Edition to get the Introductory Chapter (Anime related), the Closing Chapter and the Epilogue, that was released in 2018. I only played back in 2014, so I only got the Introductory and Closing chapters.

    Between White Album and White Album 2 I really don't know who's to choose as the best one, but I prefer the story from White Album.

    But let's end the offtopic.

    Which of the two heroines did you choose in the opening chapter though...? I have heard people saying that the choice is very difficult to make, earning a “makes me stomachache” remark from Chinese players.

    Good grief yes.  I think the two person lift sticker may have actually been factory applied.  When I built my present work area, I put some gouges into one of the work surfaces wrestling it into place by myself because I nobody was available to help me with it and I pulled some muscles pretty badly doing it to the point I was beginning to worry if I'd given myself a hernia but thankfully not.

    Mine is a 86664A 3Ghz.  Also has two person lift sticker.  Claim from previous owner is it came back from Cal in 2017 and sat ever since unused and unpowered.  I was not aware that there is a version 8664B.  Are you possibly thinking of the 8665B?

    I was in Shenzhen in October and visited one company and it was the same.

    Engineers were in charge of purchasing the low quantity but high quality equipment.
    Bean counters were only in charge of high quantity production components.

    This was on purpose divided by the management, because they wanted the engineering teams
    to have the best of the best equipment.

    One company I visited in 2018 had Rigol scopes in their production line.
    At the time they had asked me to suggest an improvement and I suggested Keysight 3000 Series scopes.
    This October they had probably around 100 pieces Keysight 3000 Series scopes installed.
    It is unreal how quick the decision making is China goes and money seems not important at such stage.

    Are those for protection against accidental bashing, accidental tesla-coiling (also known as ESD), are you working on an over-cluttered bench? Sorry I don't really get the use of those...

    Right, dust caps.
    My equipment has dust-tolerant BNCs, I'm slow enough at any job without having to fight with dust caps that will roll away and short something expensive later.
    The keysight video was interesting, I do see there can be some point in such caps but will carry on believing BNC is inherently ESD safe as the signal is very unlikely to be exposed before the ground is.

    well, haven't been here in a while, for no particular reason, since I bought the CSA8000.  By the way, that is waiting for its first sampling module.  It would have been here yesterday if the PO hadn't messed up.  It made it to my town PO of about 13k people (not like we are in NY where they could lose it), then they shipped it to another PO and then took it all the way back to the San Francisco distribution center.  I hope they don't send it back to the guy because they were nice enough to give me a return option.  But I digress...

    I've wanted an HP 3561 for a while and found by accident a 3562a locally.  Nice guy, but sometimes I wonder if they ever got anything out of this device because the settings were all over the place when I powered it up.  I have a Krell KSA50S amp that will start distorting just the high frequencies.  Turning it off an on will reset it and then it might play for a month without a problem.  The distortion is hard to catch with a scope.  Anyway, I say this so I can justify the 3562 or not, who cares, I wanted one. 

    First picture is the unit doing a sweep of a small crossover I built using the Wondom DSP modules.  They are made by a company called Sure Electronics.  They make these DSP units with/without bluetooth, with/without an amp, etc.  Very inexpensive.  I needed a crossover to drive small powered B&W speakers and a subwoofer for my synthesizer and keyboards.  Using the DSP module I threw one together in about 20 minutes.  The DSPs are supported by Analog devices graphical DSP code generator SigmaDSP.  Anyway, all is well otherwise now that I have my new most favorite piece of gear.  By the way, I thought it was a steal at $325US, what do you think?

    Jerry

    ps:  by the way, the knobs on the 3562 were cleaned in an ultrasonic cleaner from harbor freight.  I can't believe how clean they look compared to the rest of the unit.

    Good alternative, since Eneloops don't exist in C and D, what they have is adapters from AA to C and D

    Although they had sometime ago:

    (http://livedoor.4.blogimg.jp/hanagenuki-jet/imgs/f/e/fed74594.jpg)

    C type with 4xAAA inside.

    It's cheaper for the manufacture, since most of the uses are for AA/AAA (Panasonic says in the ad around 85%) but at the same time you are limited by the reduced rating of available mAh from the AAs.

    Yep, they (when it was Sanyo) manufactured C & D, I managed to snag few pairs of them, work like charm.

    The D type Eneloop uses 3 X AA cell.

    Too bad they're now discontinued.

    For me, it's more about protecting the outer ground rim of the BNC input.  And you can easily set them down on the flat surface to prevent anything from rolling away xD

    The metal BNC covers come with and without a central shorting pin.
    Though most instrument BNCs are not significantly static sensitive, and the plastic push-on dust covers are more convenient and *much* cheaper. See for eg on ebay:
      New BNC Female Cap Plugs Caplugs Lot 250 Yellow New Protection Caps Dust Cover  US $20.99 seller: eastcoastassets
    They have covers for BNC-female, BNC-male (cable ends),  N-female, SMA-female.
    [attachimg=1]

    Lots of test gear that doesn't get used all that often, and anyway many of their BNCs will *never* be used, equals a need to buy these by the hundreds.

    Apparently a similar condition is known as white coat syndrome and for an Aldi product the instruction booklet was extremely well detailed and included a reference to that particular scenario.

    My list of 'chores to do' involving getting data off old recording media, for which I needed a PC with HP-IB, was getting ridiculously long.

    Bought a cheap tone and probe set to keep in the van.  It does mapping, cable testing and NCV.  It works surprisingly well.  I tested it and not only is there a tone but the receiver lights up as well.  It came with a short jumper cable, another short cable with croc clips, some cheap 9V batteries and cheap headphones for noisy environments, though the tone is quite loud at full volume.  It is something that will very rarely be used so I didn't feel like spending a bunch, $36 USD shipped.

    Finally a DE-5000  ;D

    Bought a DE-5000 (meter only) @ Evilbay for aprox. €75 but had to pay €32 in taxes. I was expecting that. And because of taxes, I bought the TL-22 probe from another Evilbay seller, since it costed less than €22, and below that, import taxes won't be charged in my country, so it was a better move to split the items.

    I had a FTDI IR-USB board that worked with the DE-5000, just had to build some sort of support out of foam (like the one that came with the DE-5000 covering the IR port). For this, a 3D printer would do wonders.  :(

    Next on the "to do list", is learning Japanese to RTFM (https://www.ietlabs.com/pdf/Manuals/DE_5000_im.pdf) that came with the meter :-DD

    as I'm always trying to find a better way to hold the boards I'm trying to "solder".

    My "soldering" is more like a monkey poking a thing with a hot stick than anything else..  But since having a thermally controlled iron stopped me from ripping pads out, I'm hoping that having a way to position the board solidly, or at least better than with el-cheapo helping hands with alligator clips and a small tilty base, helps my "results" even more. :P

    Actually, I posted a link to a different English manual than you provided for the DE-5000, "hidden" in the "RTFM" acronym.

    I was looking for more than a capacitance/ESR meter. I wanted an LCR meter and the DE-5000 acquisition was decided long ago, but being delayed for some unknown reason. There was always some other "thing" jumping ahead.

    As an ESR meter I've been using one that I built from an Elektor magazine article (https://elektrotanya.com/esr-meter_elektor-electronics-2002-09_icl7106_by-flemming-jensen_project.pdf/download.html#dl)

    That is something to be seen when confronted with the DE-5000.  :box:

    Is has served me well enough to troubleshoot some old school boards that were used in our local water control system, and with caps in motherboards and such, were the accuracy was not the main concern, only to separate the good from the bad was really needed.

    the elektor meter is quite protected against charged caps, the de5000 is really not.

    got myself a Voltech PM100 (1-phase power analyzes) from 1999, last calibration Feb 2008 for a very sweet price. Now need to start playing with it. Yesterday evening I enjoyed 2 videos from Dave on the repair of PM300 (3-phase). Should be some fun.

    Ordered a few bits and bobs from the local store to repair the amplifier of a subwoofer I have. At the same time, I couldn't resist grabbing five Matsushita 22F/2.3V capacitors...

    BTW, f*ck Dell. I just ordered two Dell U2419, one was exchanged right away for a bad pixel, the other exhibited flickering and distortion after a week of use and was refunded.
    The exchange unit for the bad pixel one showed bad back light two weeks later.
    So, three bad units for two purchases. That's really bad QC. Even less acceptable considering it was 2x the price of a comparable Philips unit.

    Why it doesn't surprise me. They have one of the best office/industrial designs and their Ultrasharp Series when you get a good one are incomparable with the rest in terms or price/performance. The problem is the QC, it was always the QC. That's one of the things than Dell never was able to make it better, and I've been working with them since the 2000s.

    Which Fluke probe series is that ? Curious as it has the exposed metal at the end.

    Mine model 80K-40 (40 kV) has all plastic body.

    It's the vintage version of your 80K-40. The seller just connected a standard BNC cable to the end of it for the picture. I will be making changes to that area anyway.

    I have that very same HV probe, I’m pretty sure that it’s not a Fluke. I think last time I researched mine it seemed to be a Heathkit one. That is not a BNC connector either, it’s an ’old school’ threaded single pole connector.

    Ah, good to know. I couldn't find much info on it, other than a site saying that it was a vintage Fluke. For €15 I didn't really care, it will be 10 times better than the "solution" I currently use (don't ask).

    McBryce.

    Edit: A quick google and it seems to be a Heathkit 336, documentation here: https://www.vintage-radio.info/heathkit/ (https://www.vintage-radio.info/heathkit/) It'll do up to 30kV which is more than what I need.

    Now I have the Pentel Graphgear 1000 0.5mm and this one. In terms of looks, this one in all matte black and with a red line kicks the Pentel from the park in terms of aesthetics.

    Although I see this one losing the colour sooner than the Pentel Graphgear 1000. In terms of construction, well both are Made In Japan, although the first Rotring 600 were German Made and fetch a pretty penny in eBay.

    0.35mm rotring pencil was my thing during my studies. Haven't touched one since then (15 years ago), TBH I barely write at all since, for a while after the only thing I wrote was addresses on parcels my company was shipping, not doing that anymore so it amounts to almost nothing apart from signatures.
    Last week I actually wrote 6 lines or so of additional explanation on an RMA sheet and I wouldn't be surprised if it was the longest paragraph I handwrote in more than a decade...

    Another angle grinder. That makes four, all the same. Bosch GWS 7-125. They are cheap (used to be AU $75, now $85) and having several means less farting around changing disks for different stages of the same job.

    The molded carry case has a lot of internal structures intended to hold just this grinder, cord and accessories. Which make the case useless for anything else. I never use them, and in the past have always thrown out the cases immediately, as they are a waste of space.

    This time, mounting a new 'all materials' thin cutting disk on the grinder I thought hey, of course it cuts plastic too. Actually all types of disk cut plastic, or rather melt it way, but I hadn't previously thought of applying the grinder to it's own carry case.
    Anyway, all the case's stupid internal moldings were easily cut away. Now I have a generally useful small tools carry case. For free.

    About mechanical pencils...

    One day, browsing the web, I start wondering around photos of mechanical pencils and had a stupid idea. Draw a few that I liked and decided that I had to have them. Well... gathered a few dozens by now.

    [attach=1]

    The latest most significant addition to my collection was to grab this 2 out of production Ohto Super Promecha 1000S and 1500S

    [attach=2]

    I use a Rotring 600 0.5mm often. At home regularly a Zebra Tect2way MA41 0.5mm, but the most used ones, at work and home workbench are Pentel GraphGear 500 of several sizes, 0.5, 0.3 and 0.7 (0.4 and 0.9 not so much). This are my favourite cheap mechanical pencils.

    For woodworking you will better with a lead holder instead of a mechanical pencil:

    Today's 40mm triple stack of MDF for a workbench. Number of clamps available is never up to the job at hand #ruleofwoodworking I used the 0.5 for this mark out but broke the lead several times. Just done up the clamps.

    Christmas came late!

    Look what I scored! It was destined to be turned into scrap aluminum and pcb dust. For something like 50$!

    It's a NIM bin / NIM rack! "Nuclear Instrumentation Module" - the standard analog instrument system for particle accelerators and reactors alike! I have found pictures of some of these exact modules from 70's CERN photos!

    I think this setup has been used for some kind of energy /pulse height spectroscopy, likely gamma spectroscopy.

    Super high quality amplifiers - AND A VARIABLE 0-3 KV DC PSU - and a dual 0-1000V!

    Unfortunately no ADC or multichannel analyzer. Oh well. I'm happy as a pig in mud!

    What is your opinion about that Ohto Super Promecha, they look like they also have lead rotation like the Uni Kuru Toga right? Don't know that brand to be sincere.

    The Super Promecha doesn't have lead rotation. What can be controlled is the amount of lead to be exposed with each clik, and the extension of the tip (tube lead protection). About this latest feature, only the oldest "S" series as a wheel up front to pre-select a fixed amount of tip exposure. The newest doesn't have that feature.
    The currently available Promecha 500P has no selectors, the Promecha 1000P has only the basic feature of rotating the grabber to expose or protect the tip, as have all the Super Promecha, and the latest 1500P has the wheel above the grabber (middle of the body) to select the amount of lead to be dispensed with each click. I find this feature useful for thin leads as 0.3 or 0.4mm. I have a Staedtler REG 925-85 that has this feature also.

    [attach=1]

    All this Promechas are made of aluminium. I don't like the 500P because it's to light weight for me, and love the 1000P because of the mass distribution towards the tip. It has a thick grabber and light body. The other Super Promecha because of the lead dispenser selector, are prone to body breakage if not cared (dropped or bent can ruin them). Though the tips of those mechanical pencil can be protected (500P excluded), and supposedly make then good for caring around or to be inside a shirt pocket without stabbing the owner, I wouldn't recommend them for that, because of all those "twist and turns" don't make them a very robust mechanical pencil.
    But hey!... Someone that has a Rotring 600 should know that because of his weight, at the first fall, most likely the tip will be bent. Unless you place a foot under it to prevent a direct hit to the ground, and end up with a shoe pierced, a stabbed toe... and a 600 tip bent anyway.  >:D

    A note about the lead holder you recommended for wood work: I highly subscribe the choice. First, the best option is to go for a thicker lead, or the lead will be breaking all the time. But the Staedtler model you recommend has a feature that distinguish it from the traditional lead holders. It wont free fall the lead at a click, like the traditional lead holders does. It behaves like a mechanical pencil, exposing a millimetre of lead with each click. I have one of those but find it very fancy for wood working, for me, so I use a Rotring Tikky 1mm.  But if I was a Pro, I would go for that Staedtler 925-25 2mm
    EDIT: I'm thinking now that the Promecha 500P 0.9mm could be an option for this also.

    I asked about the tip rotation because I saw the aparatus near the tip on this photo, so I was thinking it was automatic or manual tip rotation:

    I know the Staedtler model because one of my friends is a freelancer for American Comics, he worked for Marvel and now he his working for DC Comics, and that Staedtler is his most used lead holder, and that functionality of working as a mechanical pencil were it grabs the lead and exposes enough like a mechanical pencil was something than my lead holder, one I used for school, the cheapest available (Koh I Noor 8201) didn't had that, if I didn't put my finger in the lead exit it would slide out and fall on the floor.

    Don't be sad, I've seen vintage multichannel analyzers - they are a large box, with inferior performance to something you can whip up today using off the shelf part. I can't find it at the moment, but I seem to remember someone did an MCA using a sound card. You can also in theory use a scope with a height histogram (such as MDO3000).

    Yeah true. I did get some kind of digital interface in a NIM box along with it, but it's undocumented, built on veroboard and the ribbon cable has just been cut so yeah, might not be feasable. Certainly isnt, i'd think. But the empty box with backplane connector is nice for own DIY's.

    Is that the unit with a faulty 1v range? If so there is a thread on here about units with the same fault.

    I looked at it but decided I don’t need it. It might be worthwhile adding your repair to that thread to update it for future users

    The molded carry case has a lot of internal structures intended to hold just this grinder, cord and accessories. Which make the case useless for anything else. I never use them, and in the past have always thrown out the cases immediately, as they are a waste of space.

    I tried to recycle one and they wouldn't even take the plastic. Those things are a total waste of resources.

    And yes, it works - I tested it with my HP calibrator.

    Seeing that it works with my existing trinocular scope is what convinced me. That almost halves the price and means it won't take up any desk space. Stumbled on this possibility on a YouTube video at https://youtu.be/8eqj632svDM

    SSD can almost always blow new life into older PC's, and the higher capacity a SSD is the faster. Just use it as your boot drive if you don't have an NVMe drive in your machine. (I have switched all my machines, even my old 2004 Dell Latitude D620, to SSD boot devices. Older devices like that D620 and two thicc MacBook Pros use SATA SSD, and all other computers use NVMe for something even faster.)

    Just got a Fluke 87V, described as boxed, new and unused, for £160.00 UK. It does indeed look as new but the most recent date I can find on any of the included docs is 2007.  Would anyone be able to date it from the S/No, which is 96350419?

    One the Black lead there is a manufacture date of the lead. It is not that easy to find but all my TL175 black leads have them. 
    With the pcb revision number, meter serial number and lead date you should be able to narrow the manufacture date of the 87V

    My latest purchase is a Pace TD100A soldering iron to replace the TD100(plastic one) that came with my WJS station .
    The new soldering iron comes with a more flexible and thinner lead and the iron itself feels better balanced.  The lead does not drag the back of the iron down.
     I always felt I was wrestling with the thing.
    Some people complained they had heat issues with the old plastic iron, but I never did.

    Also waiting for delivery of a spare hakko fx880-1 iron. the hakko fx888D is still my favourite iron even if it has a crap interface just set to 300C  and leave it alone.

    Don’t chargers monitor the terminal temperature to determine when to shut off? (I know lithium profiles don’t, but the chargers I have with lithium profiles monitor temp and stop charging if it goes over a certain temperature)

    Some manuals I’ve read for chargers with adjustable current say not to use too small a current as it doesn’t generate a big enough temperature rise to end charging.

    Definitely something new that I haven’t seen before though. Where abouts did you buy them?

    These adapters is for Nickel based (NiMh or NiCd) cell, as its only fit for C or D cell, don't think its common to see Li-Ion type in these sizes.

    Charging process use the usual primary full charge detection algorithm which most good smart desktop charger have, using the usual voltage plateau (Negative Delta V / NDV) detection as full charge sign, of course as long the user doesn't charge it at too low C.

    Most smart chargers capable of pushing 2 or 3 Amp current, which is enough for these > 3000mAh cell. Although at the photo I used is the old popular Powerex MH-C9000, as it happened it was within my reach, I used SkyRC MC3000 most of the times, which is much better charger, and it works flawlessly.

    Even though most modern Ni-Mh based desktop smart charger does monitor temp, as "part of" the protection mechanism, yes, this adapter simply made thermal sensing (delta temp in Ni-based) useless, time out protection mechanism is a must for the charger in this case for overcharge protection.

    Acquired them thru AliExpress.

    Even when we were competitively punishing NiMh (Nicads before it) cells at 8-10A charge rates Temperature was always an afterthought and while some chargers had an input for it no one used it. Delta V and generally adjustable was what was and still is used for NiMh. In our case we wanted the packs off the charger hot which lowered the internal resistance for more current out during the flights.

    For Quake and Quake 2 there are source ports that work far better with modern hardware than the originals. Many bugs are fixed also.

    FitzQuake and Quakespasm are the only two I use because they stay most true to the original as far as appearance. For Quake 2, Yamagi is my choice.

    Quake II was running 1600x1200 on my Ryzen 3700X / 5700X in full screen without modding so I didn't  :-+

    I had a minor issue with running RTCW on full screen so I ran that in a window again without mods which is my preference ;)

    Also brought the Hexen bundle just to complete the Retro set for another $5.

    Must remember to ration the 'workflow' now......

    Quake 2 engine was much improved over Quake, but there are some bad bugs ("Function Pointers Have Moved", which causes save loading to fail). I can't imagine even trying to play Quake with the original executable.

    Also, F12 is screenshot. It will be .tga format.

    Careful with those, they do have a short life, and tend to fail short circuit briefly when they fail. I also have a lifetime supply, though in my case I chose ones made in the EU, so have a collection of Polish, Hungarian and even French and Netherlands made lamps, plus a good number of pre war German made Siemens lamps, in both frosted and clear forms, with tungsten and tantalum filaments.

    With incandescent lamps recent ones are pretty much junk, never meeting the rated lifetime, and often failing within 100 hours. You cannot blame the manufacturers though, as often the machinery they are using is the old EU equipment, shipped over complete to the cheaper labour regions, and the lamp quality is as good, just that to compete on a cost basis they cut cost by reducing the most expensive item in the lamp, the actual tungsten filament length, so that the lamp runs hotter and brighter, but with a shorter life.

    Noted, also these will be used just in short run as dummy load or current limiter, don't think I will be using them for days.

    Not even single incandescence lamps in my house used as lighting, an exception, only the one in the microwave oven.

    Agree, I noticed the filament looks really flimsy and weak even cold/off, and when turned on, its gets softened, dangling and looks like the swinging weak hot filament will break at any time.  ::)

    I'm not sure about the DE5000 but usually an LCR meter uses an AC waveform to measure components, unless it is advanced enough to offer DC bias options.
    Multimeters with cap modes are slightly different, may use a DC pulse. But even then, I'm not sure you'll see much variance (unless it were a diode like you say, and the voltage was high enough to turn it on). DE5000 states a 0.5Vrms output signal.
    Title: Re: What did you buy today? Post your latest purchase!
    Post by: Mortymore on January 30, 2020, 12:10:40 am
    As far as I can tell for now, only when measuring in DCR mode (DC resistance) I can see that polarity matters, since the DE-5000 outputs an (almost) DC voltage of about 750mV. Haven't done an extensive check, I'd say that for all other measurements the DE-5000 seems to output a sinusoidal signal of almost 2Vpp for all the selectable frequencies (100Hz, 120Hz, 1kHz, 10kHz and 100kHz).

    Since one can cycle through all sort of measurement modes, I think it's preferable to respect the component polarity.
    Though, only because of thm_w question, I checked this. My feeling was that, by "instinct" the polarity was to be respected.  ;D

    Maybe there's other implications that I can't think about right now. If something else, let me/us know, please.

    Xilinx Kintex UltraScale+ XCKU15P-FFVE1517-2-i  FPGAs for $250 each on Ebay. List price $3500. Should be capable of 8x100G Ethernet.

    Sold as salvageable components on Mellanox Innova-2 Flex MNV303212A-ADLT cards i.e. PCIe "accelerators" featuring the FPGA and a ConnectX-5 ASIC.

    Hoping to desolder the FPGAs and rework them onto a custom PCB to use for development. Just one such board would save thousands of dollars - my rework station would have paid for itself!

    Hope there are no nasty surprises... the Mellanox marketing literature always says UltraScale rather than UltraScale+... but the part number looks spot on.

    After missing for 2 or 3 times the opportunity to grab a bench pillar drill from Lidl, I finally got one. This time they had an electronic speed control model Parkside PTBMOD-710-A1 for €79.99

    I'm no pro needing this stuff, so knowing that I could get one 500w bench pillar drill from Lidl costing €75, when I saw 350W models on other stores costing more than €100, I just told to myself that the best deal for my limited needs was to grab one from Lidl. Well, they weren't selling a 500w belt driven this time, but a 710W electronic controlled instead. So I grab what they had.

    The first impression is... well the laser is far from accurate. The old models didn't had one, so I supposed that if I "memorise" the displacement, it could be of some use anyway. The accuracy of the drill along the column itself seem very good, with no noticeable wobbling. The handle on the other side, could be better. Gets a bit stuck when returns up, and I'd prefer the old style with 3 handles 120º apart.

    Haven't done more than a few holes on wood, I can't say much more. There's videos on YouTube with some detail, though some are not in English.

    For casual works, and for the price, it sure will be an improvement over my drill on a column, with not much precision, speed control or accuracy.

    My recent Bosch PDP40 pedestal drill runs Lasers alignment but so far I have found it more or less useless as it can't be seen in sunlight and if you use larger than about 6mm drill bits the beams hit the bit not where you want to drill.

    It is nice to be able to drill vertical holes through stuff if you haven't had one before  :)

    i7s TWS EarPods....  Well I didn't really buy it but I was GOING to buy it but I received it for free anyways. My wife has been asking me to look for a set of AirPod-like earphones for her for several months now. It just happened that we were at a function and in the "loot bag" given to all the guests was the i7s TWS EarPods BlueTooth (Apple AirPod clones)! Everyone got all excited but given that it is in a loot-bag how much could it possibly be? My wife got a pair and so did I, so I had 2 sets to compare. And so the fun began...  :palm: .

    (https://jijike-pictures.jijistatic.com/2934186_i7tw_300x315.jpg)

    As a result I am STILL looking for a decent set of AirPod-like headphones that I can order reliably. Anyways, here's the video in case anyone wanted to see how bad these things are:

    https://www.youtube.com/watch?v=TEFreSnLCcc (https://www.youtube.com/watch?v=TEFreSnLCcc)

    To summarize:

    1. audio horribly out of sync with video (huge lag)
    2. sound quality is "meh"
    3. dodgy connectors
    4. out-of-the-box defects - base doesn't charge (50% failure rate based on my experience of having 2 of them)
    5. limited functionality (deal-breaker for me)
      - Only 5 functions: (1) play (2) pause (3) redial (4) answer call (5) ignore call
      - This means you CANNOT activate Siri or Voice Assist in your phone to do anything else
    6. no volume control

    The whole point of Bluetooth ear buds is to avoid having to take the phone out of the pocket. Due lack of features in #5 and #6 above it basically is just barely useful for listening on your computer, or listening to voice podcasts. Don't bother trying to watch a video with these... the lag is so bad that it can be 1-2 seconds out of sync with the video. Music sound quality will be a disgrace to the artist you are trying to listen to. Then again, for $5 you get what you pay for! But I know that they have these same pieces of turd selling for $20-30 and you don't know what you are buying because there are so many versions and clones out there.

    I was given the i12 version in much the same manner, but I don't find them bad at all. They are the exact dimensions of the Apple version (I think the i7 is slightly larger) and the box has the Apple rounded design. However, I think the i12 is a completely new design based on a different BT chip, so I doubt they are really comparable. The only thing I don't like are the flashing red/blue LEDs in the earbuds.

    The Ringer eBay auction: #261524911254 with some work on the sole and sides and a proper sharpen is actually very good and much better value than paying collectors prices for the real deal.

    The Baby partly because it is 'cute' eBay auction: #371990474694 is a step up from my Razor plane for model building for non Balsa use. It actually does surprisingly well on proper timber with a good sharpen.

    Do NOT buy a 1147A!
    Because they all develop a drift and after a few years they can no longer be calibrated in the DC offset and you always have to deal with such offset on the scope in DC mode.
    Get a 1147B instead, the problem was solved but they are much more expensive!

    Finally broke down and ordered one of these $43 storage cabinets (https://au.element14.com/raaco/126762/cabinet-organiser-44compartment/dp/136709102) from element14. It was a toss up between those or the $19 Duratool ones (https://au.element14.com/duratool/d00465/cabinet-storage-compartment-wall/dp/144738402?ost=144738402&ddkey=https%3Aen-AU%2FElement14_Australia%2Fsearch).

    I really wanted the $73 Treston ones here (https://www.mektronics.com.au/treston-32-clear-drawer-small-parts-storage-cabinet.html) with the sexy crystal clear drawers but according to my friendly neighbourhood chemist, polystyrene is not great, not terrible.

    Finally got me a semi-decent current probe!  HP 1146A

    $150 + tax and shipping
    That actually is a very good quality current probe for general purpose applications.
    And it can be calibrated too.

    Yeah I'm excited to have finally picked one up :D   The 1147As are a little too expensive for me right now

    Do NOT buy a 1147A!
    Because they all develop a drift and after a few years they can no longer be calibrated in the DC offset and you always have to deal with such offset on the scope in DC mode.
    Get a 1147B instead, the problem was solved but they are much more expensive!

    Hmmm, did not know that!  Good call :D  Thanks for the info.  I'll definitely steer clear of the 1147A's

    I passed by some trinkets near the checkout at the local hardware store and noticed a 3-in-1 lens clip-on kit for phones. It was under $5 so I couldn't resist. These things can be found on eBay for under $2 shipped. So I wanted to have a try since I do film most of my YouTube content using an iPhone 6. I'm impressed so far with it but I have to remove my case from the phone (which is a pain) to use it, as it needs to be flush up against the phone camera or else you get this vignetting around the frame.

    One other thing I noticed which I have had trouble finding info about (maybe someone in the forum here can help)... On an iPhone 6, when I am using the PHOTO mode it has a higher field of view than when I am shooting VIDEO. That is with both completely zoomed out. No matter what I do, I cannot get the VIDEO to zoom out to what I can get when I am in PHOTO. Someone mentioned that this is due to camera stabilization mode and that the iPhone uses the surrounding border (which it doesn't show) to compensate for camera shaking (basically digital stabilization algorithms). However, it is a HUGE DIFFERENCE in the perceived "angle" of the lens. For example, in photo mode I feel like I am shooting with a 28mm lens while in video it feels more like 35mm or even great (not very wide at all).

    The macro lens on this kit is INSANELY CLOSE. I'm not sure how useful it is because it blocks out all the light. You have to be very careful with lighting but it may be useful if I film any electronics or close-ups of failed parts. I'm fairly happy with the close-up performance and zoom of the native iPhone 6 camera, but this will give me an added level of macro performance (if I can get proper lighting).

    Anyways, this lens kit gives me a bit more flexibility when shooting video as now I can get a normal wider angle and even fisheye if needed. I have a GoPro clone (SJ4000) but I would prefer shooting with the iPhone as it gives me better quality and sound recording. Here's the review, I made a video of it (of course) showing the different lens on and off the phone:

    I bought a 2GB compact flash card because the one in my camera is almost 15 years old. I bought a PS/2 to USB adapter because I have an old PS/2 keyboard I'd like to use on a computer that has only USB (hopefully it will work). And I bought a 16GB micro SD card for no reason I can think of.

    What I actually meant to get, I completely forgot about after getting side-tracked on memory cards. So I guess I'll be placing another order tomorrow.

    I used one of those as a daily driver for years.  Only real complaint, but it's a big complaint, is the 10k sample memory.  Don't ever expect to capture any sort of long event and be able to zoom in with any resolution.  It really forces you to know exactly what you want to capture and set the trigger up so you are centered perfectly on that event with whatever resolution you need.  If you miss it, you reset and do it again with new trigger settings until you actually capture what you are looking for.
    I feel like having a cheap Chinese deep memory scope (Rigol, etc) AND something like the TDS3034 on the bench next to each other is a good compromise.  Realistically, the Chinese deep memory scope will get the job done most of the time, and if you need the better noise floor or better jitter or higher bandwidth for something specific then switch over to the TDS3000 for that test.  Plus you can take screen shots with the Tek so your presentations don't make you look like an amateur with the Rigol logo in the corner.

    I have recently purchased for my new mini-lab First two, both are highly recommended..
    Designed and Engineered in Germany, Manufactured in Poland by STAMOS Soldering.
    While I'm sure those things are fine, nothing about them is "designed and engineered in Germany and manufactured in Poland", no matter what the company says! For starters, the website says:
    Quote
    DESIGNED IN GERMANY, PRODUCED IN CHINA ACCORDING TO OUR HIGH QUALITY REQUIREMENTS!

    Our devices and their design are both developed in Germany. The entire production of our welding devices is subjected to the strict obligations of the German law and rigorous internal quality controls. The Stamos Welding Group produces in several factories around China.

    But all of their soldering and electronics gear is plainly the standard products made in Asia and rebadged for countless resellers around the world. That hot air station, for example, is actually a Xytronic LF-861D. Other stuff looks like other Xytronic models. Other items look like Yihua (or clones) or Atten. The power supply is a Twintex TPM-3005E (https://www.twintex.com.tw/webls-en-us/product-Single-Output-Programmable-Linear-DC-Power-Supply-TPM3000E%EF%BC%BFSeries.html), other power supplies are other Twintex models, and several Korad, Yihua, etc.

    So while I think those are perfectly adequate products for normal use, just don't be under any illusion that the German company did anything more than import them and maybe have a German manual translated.

    Exactly! I guess they mean "design" as in "trade dress", insofar as they designed the front panels to match their corporate design. :P

    For sure, it's possible that they've submitted the units for compliance testing, etc. Maybe they've even had to suggest/request/demand some changes in order to comply with EU regulations. But there's zero chance that they're designing them in-house and then just outsourcing the manufacturing, as their wording suggests.

    Finally broke down and ordered one of these $43 storage cabinets (https://au.element14.com/raaco/126762/cabinet-organiser-44compartment/dp/136709102) from element14. It was a toss up between those or the $19 Duratool ones (https://au.element14.com/duratool/d00465/cabinet-storage-compartment-wall/dp/144738402?ost=144738402&ddkey=https%3Aen-AU%2FElement14_Australia%2Fsearch).

    I really wanted the $73 Treston ones here (https://www.mektronics.com.au/treston-32-clear-drawer-small-parts-storage-cabinet.html) with the sexy crystal clear drawers but according to my friendly neighbourhood chemist, polystyrene is not great, not terrible. The $43 Raaco one is steel and polypropylene, the datasheet even gives a max load rating of 33kg which is a nice touch.

    I have a treston drawer (different one though) myself which I think is fine. I just need to find a place where I can get the cross dividers for cheap!

    RS010N, only needs 2KVA and a single phase supply is just fine.

    20 years ago the controller was 3 phase only, the size of a VERY large fridge and weighed 150Kg. The controller for this latest model is in the smallest box on that pallet. Weighs only a few Kg but throws the robot around like a rag doll - over twice the speed of the old controllers.

    At the tool tip you can get speeds of 12m/s and repeatability of 0.03mm over that 1.4m reach.

    https://robotics.kawasaki.com/en1/products/robots/small-medium-payloads/RS010N/

    They had a 1500Kg payload version at the warehouse when I picked this one up. Didn’t ask the price of that one (this one was about £25k)

    (For those who don't realize how fast 12m/s is, it is about 43 km/h or 27 mph.  Scary fast for a metal dildo arm to whip past your head, or any other body part.  The acceleration and jerk (third derivative of position) involved must be rather.. interesting.)

    Used JBC AD2700 for $110.

    I have a Hakko 888D that I love but I'm curious to experience some other stations in case they are much better (as some people say) and it'd be handy to have a second station because it seems to take 10 minutes to change the tip on my Hakko.

    Haven't pulled the trigger yet but the price seems to be right and people in the forum say it's representative of JBC irons.

    Changed my mind at the last minute and ordered an Ersa i-Con Nano with a few chisel and gull-wing tips.

    Maybe a waste of time since I already have the 888D with BCF tips but I want to see the difference for myself (and having one iron that's slow to change tips on is leading to often not using the tip I want.)

    I'm a long time Ersa iCon user and can fully recommend them. But if you want to regularly swap tips while the iron is hot, then I'd advise you to invest in a second (or third) tip holder. This isn't part of the tip and is extremely difficult to swap from one tip to another when the tip is floating around 360°C.

    Thanks for the tip. I did see this recommendation in the forum archives earlier and so I ordered a separate tip holder for each tip.

    Should be interesting as I’m fed up with scrubbing everything I make with IPA, then rinsing, then scrubbing some more to get the flux off. Apparently with this flux core solder you clean the PCB in water then give it a quick rinse with IPA to get rid of the water and you are done.

    It’s a lovely quality thing and some superb operator and service manuals all available online.

    Blood pressure, blood oxygen, breath C02, temperature, ECG (3-12 lead) all monitored and logged automatically. Internal (chest open!) and external defib paddles, normal disposable defib pads. Bluetooth, ethernet and RS232 interfaces, 2 lithium battery packs with calibration function, continuous background self checks and results logging. Voice recording, voice prompts for AED mode, pacemaking, manual defib. Built in printer...

    Astonishing things!
    Boots up ready for use in less than 2 seconds, non of that Linux/Windows nonsense in these!

    A box of fragments.

    HP 66312A 0-20V/0-2A DYNAMIC MEASUREMENT DC SOURCE
    Basically a DC power supply with lots of dynamic monitoring features.
    Won for US $21.50 but it's heavy so the shipping (via ebay Global Shipping Program) was costly:
      Domestic leg         $65.45
      International leg   $61.28
      Import charges     $19.41

    And then... it arrived massively smashed.

    It could be worse. According to ebay on the phone just now, they are going to refund in full. Item plus shipping.
    This means I get a free jig saw puzzle to try and piece together. Visually it appears all the electronics survived, amazingly. But powering it up will be the test. Most lucky: the VFD is intact.  In fact the whole front display board seems undamaged, apart from some bent tabs on the spinner wheel sensor. So the thing may be salvageable. Though it's never going to look pretty.

    Heh. Someone has never tried living in Australia and paying US to Oz shipping costs. In US dollars times 1.5 (USD to AUD exchange rate) plus our lovely 10% tax on the purchase PLUS the shipping. And if I ship via my reshipper in CA, ALSO the commie-fornia tax on everything passing through.

    No, this one is living with it's scarred face, and liking it.

    Update: Ebay did indeed refund both item cost and shipping. So the lesson is, if you receive something via ebay Global Shipping Program, and when you receive the parcel it looks even slightly like the contents may be damaged, take lots of photos of the process of opening it and checking the contents. I've not used GSP much yet, and the few previous times I did were OK. But it seems the system may have a black spot or two.

    Ouchy  :'( There is only a rear end for that case series available https://www.thingiverse.com/thing:2186112 (https://www.thingiverse.com/thing:2186112) so it could be adapted to take either a Laser Cut insert panel for the buttons and bits might work better than all 3D printed. Or from scratch not that hard to make one up but I would still favour a Laser cut panel inside a housing.

    At least it works and the price is minimal I guess  :palm:

    I'd just make a clean cut, 3D print the end section and bond them together.

    Oh, and I should mention, today I bought 100x KM4164 64Kx1 NMOS DRAM. I do a lot of retro computer repairs and go through a massive amount of these.

    Time Base : 2ns/sec ( min )
    Vertical :1mV/div (min)
    Acquisition : Envelope
    Trigger Source : CH1
    Trigger Coupling : DC
    No Probe Connected
    All CHs are GND'd
    Is that Noise Level normal for this type of oscilloscope ??

    It is all so random. I just received my 6612C, also using GSP, and it was USD47 for shipping from the US to Brisbane, plus USD28 import charges (although I paid USD179 buy it now). I believe mine weighs a little less, but still. Luckily mine arrived in great shape. Only complaint is my VFD is no great. It will do, but watching for a cheap replacement.

    TerraHertz: putting the bits back together will go reasonably well if you use the liquid styrene plastic model cement from a hobby shop. It’s typically methyl ethyl ketone or trichloroethylene, if it is available in Oz. MEK works best but it’s not available worldwide these days.

    Had a similar problem on an HP E3640A, not as smashed as yours but it did go back together with minimal scaring.

    For ABS plastic stuff, you can make a slurry out of ABS shavings and a little bit of pure acetone, and use it to cover any small holes, or to weld two ABS edges together.  It'll leave a bump and a visible scar, but it does fuse the ABS together and leaves a stronger joint than any glue.

    MEK does the exact same thing, and is also called butanone.  They're neither cements nor glue, really; they dissolve some of the material, so are basically welding agents.  If used in the right amount (not much; just enough to fully weld the mating surfaces), the join has the same properties as the original plastic.

    Bought this a few months back but forgot to share, it's the FY6900 signal generator that you can find rebranded everywhere. It was about 80 dollarydoos.

    It came DOA and yet suspiciously plastered in QC Pass stickers with a birth certificate only a few weeks prior. Of course as an Eevblog member I could not just return it to the seller so I promptly destroyed some 'warranty void if removed' stickers and took it apart.

    Oh there's your problem... the main PCB wasn't connected to the power supply.   :-DD

    It takes a bit of faffing about in the menus but you can change it from Chinese to English in case anyone wanted to buy it cheaper through Taobao or the like.

    Yes.  I get the same thing on a TDS3054.  These scopes use CCDs for their acquisition which are inherently noisy, and also experience a lot of drift.

    You are using infinite envelope mode, which is essentially doing a peak detect over the run time with infinite persistence, plus full bandwidth.  You are going to see the worst of the worst.

    MEK not available you say? Here's my plastics repair kit:

    [attachimg=2]

    4 L of MEK and  glass syringe with fine needle. And G-clamps, tape, etc.
    The supplier was out of stock of screw-top tins when I bought that, darnit. So paint tin it was. I must find a screw top tin, that thing is a pain to open. And wow, the evaporation rate! On the plus side, bulk MEK is remarkably _pretty_. Hard to describe, but it is.

    The bent metalwork is all straightened out now. It remains to be seen how many plastic fragments are missing.

    Edit to add: A couple more things arrived. After the box of fragments, I've got a box of air, and a box of nCoV.
    The first is a module extender for a HP 83480 scope. Yes I finally bought some actual plugins for this - http://everist.org/NobLog/20141029_HP83480A_teardown.htm, (http://everist.org/NobLog/20141029_HP83480A_teardown.htm,) on their way now. Only took 6 years before I could afford them.  The extender pretty much is a 'box of air.' Quite expensive air.

    I'm in the business of seeking/making an ideal bridge rectifier (this is my weird hobby, like some people do volt-nutting). Thanks to AoE I got to know about FERD diodes. Now I got some.

    0.25V dropout at 1A, 0.28V@2A dropout (went down to 0.27V after self-heating) at "room temperature"... Not ideal, but good-enough so I can ditch lt4320 in favor FERD in my designs. Here is the datasheet if someone interested: https://www.st.com/resource/en/datasheet/ferd40u50c.pdf (https://www.st.com/resource/en/datasheet/ferd40u50c.pdf) . Didn't measure reverse current, it's probably very high (esp. at elevated temperatures), but that's not a concern for me.

    I promised my wife I would stop buying cheap watches... as I went on a bit of a rampage over the past few months once I discovered a bunch of very interesting-looking options on eBay. Hey at least they didn't cost that much... unlike some other hobbies people can get into. And I made the excuse that I was getting them only so I could do YouTube video reviews (although she caught on to that lie pretty quick).  :-DD 

    Anyways, my latest purchase is the Jaragar A034 (far left in the video screenshot below) which just came from China (hopefully not laden with coronavirus although if you see me stop posting in a month, you'll know why). Still fresh from my watch-binge (buying 3 oversize watches) I found this $18 automatic skeleton watch with a slide rule bezel which I really enjoy having. You will see by my video below that I already owned an older automatic Citizen handed down (although I can't tell you the year it was made... maybe one of you knows) and a slide rule Seiko Flightmaster which is much more expensive that I didn't want to wear daily. This Jaragar is cheap enough but still looks sophisticated with the skeleton and slide rule, and is automatic. Here it is compared to the other 2 watches I just mentioned:

    https://www.youtube.com/watch?v=i1R99-GFejs (https://www.youtube.com/watch?v=i1R99-GFejs)

    I know how to use the outer 2 rings of the slide rule... but I have not figured out what to do with the inner rings. The inner-most starts at 0 (or 30) at the 12 o'clock position and goes 0-30 evenly. The next-most ring has 120 at the 12 o'clock and increments non-linearly but going counter-clockwise with 160 at the 9 o'clock, and 240 at the 6 o'clock. Somewhere around 4 o'clock is says BASE 1000 M and then the first number at 3 o'clock is 55. Any ideas? See this photo:

    [attachimg=1]

    And in case you haven't seen my other 3 cheap eBay watches which I bought (the Jaragar above would be my 4th.... the other 3 were composed of 2 SKMEI's and 1 no-name Diesel knock-off), the video is shown below. Remember these were all under $20, some were under $10. I bought them to have a little different variety during the week and they look interesting but they are HUGE. I guess I was rebelling since I have been wearing this pinsky little Garmin vivofit4 for the past year. I have a few digitals but few analog watches and the ones I do are more expensive that I would want to only wear to events and formal situations, not as daily beaters or for casual outings. Therefore, to go the other extreme from my vivofit4 I decided to find the BIGGEST GAWKIEST oversized monstrosities I could find just to have a laugh at the entire style but not break the bank. Obviously my wife did not agree with my humor.  :-DD

    I have had mine for a while and it does what I need. @bitseeker no they are not internally shielded like the real deal.

    Given the price disparity and the totally OTT premium Agilent and now Keysight charge for them worth the small risk in particular with Paypal as a DOA warranty.

    As far as I know they tend to work well initially but don't always last. That was a while back though, I'm not sure about current versions.

    I was given one of those HP USB-GPIB intefaces (it was included in a box of random cables I bought), but I've never tried it out. I'm not sure if it's real or fake. Is there a thread showing the differences or how to tell which it is? And what software can I use (Win 10) to test it. Does it show up as a COM port?

    In my favorite scrapyard I bumped into these three (two and a half) Bernstein TH PCB clamps from the 80s.
    I own the new brown Bernstein generic clamps but always wanted to have these.
    Now for only €5.- a piece it was a nobrainer.
    Have to clean them, gently grease the mechanism and restore the mechanism to clamp the part to the pcb while soldering the other side.

    You can start by installing the Keysight Instrument Control Bundle (https://www.keysight.com/main/software.jspx?ckey=1184883&lc=eng&cc=US&nid=-32516.426029&id=1184883). Other software that supports the VISA standard generally works once you have the Keysight drivers installed (via the linked bundle). If you want to develop your own software, you can use a VISA-compatible library for your favorite programming language. For example, PyVISA enables you to talk to GPIB devices using Python.

    ... Not ideal, but good-enough so I can ditch lt4320 in favor FERD in my designs. Here is the datasheet if someone interested: https://www.st.com/resource/en/datasheet/ferd40u50c.pdf (https://www.st.com/resource/en/datasheet/ferd40u50c.pdf) ....
    Just curious .. what don't you like about the LT4320 approach? I've made 100s devices over many years without ever an issue? Even up to 50A bridges

    It is pricey, and I had troubles buying one, as available distributors didn't always have it in stock at the time. I also found it is hard to route on the pcb. It also specifies minimum output voltage of 9V. Frankly, I haven't even tried it yet, as I was worried to burn one, and not to be able to buy a replacement.

    Now I buy from Mouser, so not a problem. But now I'm thinking that for modest currents of 2-4A I might just use these beefy diodes. One might ask why bother with active rectification at such low currents, but it does make a difference when voltage headroom is small, and the plastic enclosure doesn't let dissipating much heat.

    Fair enough if price is an issue. This is one of my bridges (5A) using their SMD with thermal pad. They also have a DIL version. A less than 1" squ PCB, with FETs shown, at 5A, it barely gets warm. (I even use lower Rds FETs). The SMD looks like a bastid to solder, but I worked out an easy assembly plan. Voltage drop is absolute minimal.

    What's wrong with it? Also repaired an X360 that was going to go to the trash, but didn't find the schematics... fault was no power, found the problem by observation/luck, small SMD cap next to the RAM looked a bit strange, popped it off and bam. Used it for a couple of months since I had wanted to try the convertible form factor, then sold it and bought an XPS 13 2 in 1 since I was convinced (HP was 15", so ok to test the concept but way too heavy and bulky for it to make sense beyond that, and also it was slow as a dog).

    No power as well.

    One of the SMD caps shorted for the AC-INPUT to ground on the VCCSA power rail (for the CPU I think). I replaced them and it worked for a few minutes but now it's dead again, I need to do more troubleshooting.

    I've found online that it's fairly common for caps on this machine to blow up all over the place, very strange.

    Cracked (and hence usually shorted) ceramic SMDs are quite common in laptops, usually because the board can flex due to lack of fixings between the board and case or because the entire device flexes.

    Way back in 2014 I bought a HP 83480A scope mainframe, without plugins. It was pretty cheap at US $112, a whim buy, and I'd expected to buy some plugins fairly quickly, assuming they'd be in similar price range.
    Oops! Turns out the plugins are still compatible with current high-end Agilent/whatever-their-name-is-now, and are ebay-priced in the thousands.
    So the scope frame sat around without modules.

    Till now. The modules I wanted (HP 83482A : 30 GHz integrated optical channel and 40 GHz electrical channel) are still up in the thousands. My second choice (HP 83485A : 20 GHz integrated optical channel, and 20 GHz electrical channel) are usually pricey too. But a couple came up closer to my range. After some bargaining, I got two for US $450 each.  The pair are exactly the same functionally, except produced before and after the company changed from HP to Agilent. More than just the logo on the fascia changed, so they look a little different. No matter.

    [attachimg=1]
    [attachimg=2]


    It's interesting that almost always, when such modules are listed on ebay they are missing the _essential_ APC 3.5 f-f gold plated port-savers, and SMA shorting or 50R caps. Which just shows that the sellers have no f-ing clue what they are selling, because these inputs are rated +-2V MAX, and this is not a joke. Reading the manuals, the absolutely required anti-static measures are extreme.  For instance rigorously shorting the internal conductor of coax to the shield, and both to the module frame, before connecting the cable to the port. Coax cable is a capacitor, and can accumulate enough charge to kill these delicate ports.

    I've seen one of these type inputs get static-blown by some fool (my boss at the time) casually touching it, and it cost multiple thousands and a long delay to get it repaired.

    Why are the port-savers almost always missing on ebay units? Yet the prices are still thousands, as if the units are 'known good' - which without static protection on the ports, they are absolutely NOT.
    Maybe ebay sellers think "oooh, pretty gold connector, I can sell that separately." So they remove them, very possibly static zapping the input in the process, but also not knowing....

    These APC connectors are easily damaged by mishandling. One thing NOT to do, _ever_ is rotate the mating connector. This can spall the precision gold plated mating surfaces. Instead one MUST rotate only the outer stainless steel nut, while holding the inserted connector motionless apart from being pulled carefully inwards. Then torque to a precise tightness.

    Another thing to NEVER do, is insert an SMA connector into the APC 3.5 port on the sampler. They do fit, but SMA have looser tolerances and can (likely) degrade the APC 3.5 connector.  Hence the use of sacrificial APC 3.5 female to female connectors in these ports. One end only ever touches the port's APC 3.5 and just stays there. The other end gets SMAs attached. Once it's become worn, it's replaced.

    Anyway, this seller's modules were minus the APC 3.5 and shorting cap. Typical. Which means they might be blown. I explained the static issue to the seller and asked if he could please form some al-foil over the ports, for shipping. The modules would be handled by staff at my US reshipper, and they of course can't be expected to understand the static damage risks with exposed APC ports.

    So what did he do? In preparing to pack and ship he very kindly screwed SMA bulkhead f-f connectors into all four ports, then 'closed' them with short SMA cables. Sigh. By the time he sent me photos it was too late, done and posted.  I sent him a page from the manual about care and handling of APC 3.5 connector ports, so maybe in future he'll know.

    They arrived yesterday, after some nerve-wracking hickups. No shipping damage.

    [attachimg=3]

    Fortunately he only made them loose finger-tight, and visually the APC 3.5 surfaces look OK still. I hope to try the modules tomorrow, fingers crossed.

    Here's inside one.

    [attachimg=4]

    Now I have to find four of those APC 3.5 (f-f) port protectors. So far, no luck finding any. Maybe I'm searching wrong, but I can't find any on ebay, or even who makes them. I don't expect to be able to afford new ones.

    [attachimg=5]

    Anyone know where I might find four of these, in reasonable condition?  (Not that I can properly gauge them. That's another thing I need to buy at some point.)

    In the meantime I can 'borrow' some from a HP 54121A sampler head. But swapping them back and forth defeats the aim of minimizing wear on the ports.

    Edit to add: This is what APC static-sensitive ports should look like at all times when not actually in use;

    [attachimg=6]

    And this is what they typically look like on ebay. For such prices you get to roll a dice:

    Sounds like there's an interesting story there. Small business, bit eccentric. I like the personal accolades visible in the page source code. Like "Dr.Yuk exudes a degree of creative instinctiveness..."


    Hmm. Searching ebay for HP 54121A, there are _so_many_! Most with nearly identical prices. Most without those port protectors, and ALL without the quite special interface cable to the HP 54120B mainframe, without which both are useless.
    Where do all those port protectors go? Gold scrappers maybe? Arrrgh.  And the cables... but what else is new.

    But a few do have them. Let's see if they'll take a sensible offer. Aaaand no, they won't.

    I haven't bought real Kelvin crocodiles with one wire going to each side of the jaw yet, however as I actually wanted to use the TL-21 for something I did lengthen the Kelvin wiring keeping the original crocodiles.
    While doing that I noticed that the TL-21 fixture has a small un-wired PCB on the upper portion, I peeled the adhesive that has the "TL-21" marking off out of curiosity and found that it's an option with footprints for measuring SMD's.

    Most likely people who toss these kinds of modules consider them as worthless scrap and don't think anyone would use them again, but the expensive terminations are still usable with their new equipment so they'll keep them as spares. So the scrappers who get their hands on the modules and resell them on ebay etc never see them, and that's why they're unobtainium.

    I feel guilty about this because I already have a Hakko 888D but I've never tried another iron and want to experience the difference for myself. That and I wanted a second iron because it takes a long time to switch tips on the Hakko which often leads me to not using the one that I really want.

    So far I love the Ersa. The feel is great, solid but lightweight, and my first attempt at drag soldering small SMD with the miniwave was much more credible than my past attempts with the Hakko CF tips. (But I also used Amtefh tacky flux instead of my Chip Quik no clean flux pen and that might have helped too.)

    (I'd been about to buy a cheap second hand JBC but the stories of lousy expensive tips chased me over to Ersa which is also easy to buy here in Europe

    For DER DE 5000 owners :

     I did some conversion to Kelvin probes at mine instruments a few years ago. The best thing I could do to this instrument :) . It is so much comfortable than that a crocodiles.

    Nice!

    FYI, though, I would rename it to "kelvin clip conversion", because kelvin probes actually do exist, and they're a different thing: they're actual multimeter probes, but with two wires going into each probe tip. For example, the Pomona 6303 (https://www.pomonaelectronics.com/products/dmm-test-leads-and-probes/kelvin-probe-set).

    Just refunded the little cute laptop I mentioned a page ago. Can't put up with the lies.
    I totally understand it's a hard time for anyone in China to ship, but at least just be up front.
    They totally told me they would ship on 26th, so I sent my barely hanging other laptop to service that day, expecting to have something else to use in the meantime.
    Nope, they said they are going to ship today, which means my weekend working plan is f*ed, but hey, at least I should be covered by Monday, right?
    No. They told me to wait for another week.
    Making things worse, they always promised to ship before today, and only gave me the truth today.
    And the final blow is that they provided me with a fake tracking number on 26th and that number shows waiting for collection for the past 3 days.
    So, screw them. Someone else gets my money,

    Are they lying tho? I’ve had numerous shipments from China delayed by at least 3 weeks. Several reputable companies that I deal with frequently told me the government has only just allowed them to reopen for business.

    The problem is not that they can't ship, but they told be the could but they really couldn't, and they sent me a fake tracking number.
    Just to double confirm, they swiftly accepted my refund request, and there's no way they can do that with goods already shipped.

    Ah, fair enough - bullet dodged then.

    FWIW, Reichelt has Felder desoldering braid in 15 and 30m spools. (They don't seem to have Stannol braid at all.) But good choice, the Stannol braid is excellent. (It and MG Chemicals are my two favorites, as they have far finer stranding than other braids.)

    Big grin on my face. When I started out in the 1970s, we already used Stannol solder. Even after all these buyouts, they’ll probaby never die and still make good soldering stuff. I still got a roll of 60/40 solder lying around somewhere. For lead-free, I use Felder nowadays.

    A very large old spot welder. Water cooled, pneumatic plunger, controlled weld timing. 400V AC supply, which means it runs the single phase weld transformer across 2 phases of 3 phase 415V.

    Another restoration project. Surprisingly it actually contains some electronics. 'Solid State' they proudly boast, which gives an idea of the vintage.

    It's home now, but I still have to get it off the trailer. Plan involves a large improvised timber tripod and a chain hoist. Tomorrow.
    The thing is immensely heavy. I don't even know if my 1000Kg chain hoist will be adequate. Might have to buy a bigger one.

    That hoist should handle it comfortably. Nice find and knowing you you got it for a fair price.

    It did.

    Took most of the day and some false starts to get the tripod built and in place. In the rain. Once it was up and positioned right, the spot welder lift was easy.

    Why do I need such a big spot welder? A: I don't. What I wanted was almost any second hand pedestal spot welder,  for a cheap price. Ideally one in working condition, I wasn't having any luck finding one, then found this. It's NOT in working condition, and needs plenty of work to restore it. But otoh, it has full cycle control and is massive. Able to do any kind of spot welding I might ever need.

    I've just bought a PC gaming accessory... for my soldering needs. Apparently, among the PC gamers, who swear by their corded mice, a "mouse bungee" is a thing. In case the photo doesn't explain it sufficiently, those things sticking out are springs with just enough stiffness to support the loop of cable under its own weight while allowing enough give to be comfortably flexed in any direction. I figured it could help me deal with the problem of the soldering iron cord always getting in the way and annoying me to no end and indeed, it seems to have done the trick. While it doesn't seem like much, it allows for just enough cable for it not to keep getting in the way while being able to comfortably reach my whole working area.

I ended up with the 240 AD with a viscosity of ~1500 cSt, I have no frame of reference as to how goopy that stuff is but I'm sure it's more than good enough to lube my torches with...probably.  ^-^

    And I got a cheapo sound level meter and lux meter. I have a G Shock that needs 50,000 lux for 5 minutes a day and I needed to know if I can just leave a flashlight blasting at it a few times a month.

    You need a set of viscosity cups so you can check the claimed viscosity when it arrives. Heavy oil or Glycerin is close unless you want to add the cups to the collection  ;)

    Just received a bottle of Isopropanol to replenish my stock.

    I kind of feel sorry for our useless GLS delivery guy. For the past few years, he was able to wrongly claim that no-one was home and dump all the parcels at the local pickup shop, having not even attempted to deliver anything. Now that everyone's stuck at home, he'll need to find a new excuse.

    Hand sanitiser, direct from the production line. Helps to know a canning factory near me, who supplies us with some products, and he is running a batch for other customers, but is close to running out of raw ingredients, because for some reason, they are not available.

    At least I got 10 cans for me, and enough for everybody else that ordered as well, and there will be another delivery tomorrow. Unlike the rest of the price gougers, who charge a minimum of $7 a can, these came in at under $2 each. After the neighbours got I have 6 left to last me for the quarantine period, and should be way more than enough. 3 weeks self isolation coming up soon...........

    Knipex 8 inch long nose pliers with knurled jaws (product number 26 11 200).
    These appear to be well made.

    Glow-in-the-dark paper, 8.5 x 11 inch.
    Very fun stuff. You can draw on it with a small flashlight or UV laser. It is responsive to white, purple, and UV light, but not at all to red or green light. I didn't try blue light.
    It glows quite bright when exposed to bright light.

    Two buys today:

    Another (the third now) Aidetek Box-all 144 SMD case, because after testing many different systems, these are without a doubt the best SMD sortment cases around.

    And a spur of the moment buy: A Fluke 8060A because I sold my original and regretted it just days later. For €40 in great condition, calibrated and fully working I couldn't pass it by.

    Nice purchases; I will look the SMD case later today - still looking for a definitive and space-saving solution for that.

    I have been on the fence to let go of my 8020A, 8060A and 8062A but just couldn't have the heart to do it yet. The first is a family treasure, while the two others are simply excellent units.

    Very very interesting, thanks for sharing!

    They are quite reasonably priced on eBay/Aliexpress, I think I may have to pick up a couple of the 96 size ones. I was just thinking the other day that it's such a waste of space to use the trays on a pull out storage cabinet to store SMD parts.

    JFYI there are two versions of aidetek cases: esd-safe and normal. I don't have a normal one, I have two pieces of esd-safe (black ones). They are made of conducting plastic.

    Post by: McBryce on March 26, 2020, 08:32:12 am
    I only have the non-ESD safe versions at the moment as I only needed storage for passive parts. I may get one later. I'd recommend the 144 version over the 96 version. The size difference is minimal and the 144 trays allow you to have a complete set of resisitors and capacitors of one size in the box. So I have a 1206, 0805 and 0603 box now.

    I'm currently working on a 3D printed version so that you can make your own. The picture below will be a 4x BNC version so that many different probes could be attached. Just waiting for the sockets to arrive now. The PCB is just a trial at the moment too. The PCB needs to be 1mm thick which I also needed to order, the PCB in the picture is 1.6mm and doesn't fit into the meters slots.

    Got to take the garbage out on the appropriate day, so will be touching things. plus communal living, so there are other people around, and I have to at least walk a little to the bin. There are only 7 bins, and they need to go out, or else we will have a big rat problem, as it is the weekly collection does mean I can feed a whole gecko population on the maggots that grow. Our cleaner is at home as well, so if I do not none of the others will take them out, either from being old, or from being unable to look at the crawlies while dragging the bins up the drive.

    Going to be fun back at work, no collection for a month, those bins will probably fly themselves out, if the monkeys have not picked them clean. Probably have another green Mamba under there as well snacking on the wildlife. Dave does not have all the deadly wildlife by him, I have at least 4 deadly snakes common by me. Black and green Mamba, night adder and spitting cobra. Puffadders further inland though, who do not move when you come towards them, as they are ambush predators.

    I had my tonsils out at 33.  I avoided too much pain through my Dr’s understanding that I had no interest in feeling any pain after the surgery.  I departed the hospital with a great big bag of the finest painkillers available to us mortals with a clear understanding that the drugs where to be administered by My wife and I was not to leave the couch.  I spent 10 days as a drooling potato living on iced tea mashed potato and gravy and ice cream. 

    To be honest even after I came off the painkillers it was painful I would hate to think how painful it would have been if I was coherent

    I've been needing a vice for ages but I always go back and forth between buying quality used gear vs new cheap junk from the hardware store. I think I overpaid a little at 150 dollarydoos but it was local and I liked that it had the original paint on it...or what's left of it.  ^-^ Brand new is around $483 so not great not terrible all things considered. Spare parts are available too but it just needs a clean and lube.

    Can't wait to clean it up and finally use my new (old) Atlas Copco air compressor from 1989, a mate gave me a 3M spray gun so this will be fun.

    Also I built a USB 2.0 switcher box, so I can switch back to my beloved Apple USB keyboard (pre-butterfly mechanism, the same thing on 2012 MacBook Pro and AFAIK 2019 16-inch MacBook Pro.) That thing is a bliss to type on.

    The MacMini is connected to a 8+2 GbE+10GbE hub with VLAN, and the link is VLAN tagged to two sub-links, Internet and Ethernet. The Ethernet VLAN is then untagged by the hub and distributed throughout the internal network.
    This is similar to how I do things. I don't have 10GbE at all, so I use 802.3ad link aggregate as the substitute. I have a repurposed used cash register motherboard acting as my router, linked to my main switch over a 2-way aggregated trunk. My Internet comes in as PPPoEoV (PPP over Ethernet over VLAN) from the ISP, then enters my home network using a second VLAN. That is in my wiring closet. My lab and equipment rack is in a separate room with its own rack top switch, linked to the wiring closet with a 8-way link aggregate. In the rack lies my NAS with its 4-way aggregated link, my daily driver Hackintosh and my HPC workstation

    Quote from: blueskull on April 04, 2020, 02:48:52 pm
    The only bit of shame is that Windows don't support simultaneous VLAN (unless you use a vendor tool like Intel's NIC toolbox), so I'm stuck with simple connection to the hub. This is not a problem since I do have a server to handle unsafe traffics, but if I want to use my own laptop as a server, I would not be able to do that.
    You may want to explore the Windows PowerShell a little. Windows 10 Pro have those features, but it is tucked away in Windows PowerShell. (My HPC Workstation uses Windows 10 Pro for Workstations, which have a few more features like ReFS.)

    That would be in violation of several IEEE standards. Don't you mean "switch?"

    Here, I've got the next generation network under construction. Today, machineroom has a 7200VXR router, and a 4948 switch, all Cisco. Media cabinet has a 2960 24-port PoE switch; a similar but 10-port model sits in a linen closet upstairs. 5x 2702 access points supply wifi.

    The next generation will swap 7200 and 4948 for a 4500-X router/switch, and replace one of the 2960s with a similar, but 10G-connected one. Just need to find out where I put those two 10G dual-port nics i bought, so file server (OpenAFS) and VM host (ESXI) can get connected.

    It's within spec. No different than what a CPU has to bear in pretty much every performance laptop (and it's usually not the CPU dying first on those).

    It's probably fine for at least the 3 year warranty, you can always get the $20 Intel insurance if you're worried they will give you trouble for overclocking it (on a technicality most motherboards overclock by default and Intel may try and swindle you).

    I wouldn't be able to sleep at night knowing the CPU is throttling not to mention the fan noise and power consumption. I'd just lower clock speeds by like 5% for the peace of mind.  :P

    Quick 6101A1 fume extractor.

    Since I added a room filter with an auto/sensor mode it's clear that y desktop smoke absorber isn't effective. Just five minutes of soldering with tacky flux and the room filter kicks into overdrive to clean the whole room.

    I bought from Eleshop.eu who also made a great comparison page including video/audio of various brands/models at different settings https://eleshop.eu/knowledgebase/FAQsolderfumeextractors/

    I moved most of my proper office setup back to my home office for coronavirusmas, but didn't take my solder fume extractor (metcal BVX-201) because it's pretty big and setup in/through my office desk and seemed lile a bit too much effort.

    I had my dyson air cleaner fan running in the room just for a bit of airflow, and it went crazy when I did some soldering. Nice to give the VOC sensor a bit of a test..  I got it during the fires so it's had a lot of chances to show that it's very good at sensing and removing PM2.5... now I've also seen it on VOC. ;-)

    And now I'm reconsidering moving the fume extractor....

    I'm on a NIM (Nuclear Instrumentation Module) binge!

    Just received these; a dual logic pulse counter, and RS232 computer interface for it, and a single channel pulse height analyser (window discriminator).


    I must admit, I have the same admiration for these modules that people has for aerospace/space electronics and parts. These modules are produced in fairly low volume, and

    identical units has been used in most if not all famous high energy physics experiments since the mid-60's, from reactor monitoring to particle accelerators, diffraction studies, cosmic ray observatories, and so on.


    I'm hoping to get some modules some day with 'famous' lab inventory labels, like Oak Ridge NL, Los Alamos, CERN, etc.

    An oldie but goodie, an Icom IC-28A 2m transceiver. 25W, 21 memories, 3 of thechannels are for using tones but will be used mostly for simplex.  Good reviews on Eham.net. I like the older radios, easier to program. Will do a complete realignment when it arrives.

    In my case the building has already IT infrastructure there, so I don't need to worry about WiFi, thus no PoE.
    I don't really care about a router too as my Internet traffic is small enough (~300Mbps) to be handled perfectly by a MacMini.
    I use a 10G NIC on the MacMini and a 10G switch simply because I use my MacMini as a router and VPN, so traffics circulate in and out of it, thus I need more BW.
    Ah. In my case this is the building network. This is for home. I've got 500/100 now, apparently, since the ISP decided to upgrade for the duration of the current biological situation; normally I have 100 symmetrical. The first router was a Cisco 1800 one, but I swapped it for a 7200VXR because I wanted to run a few IPv6 bells and whistles that aren't supported on the 1800. Also, it's got 3x GE on the motherboard, so fit well with the upgrade to fiber connection, which always links up in GE, regardless what one bought.

    The switch I use is a NetGeat GS110EMX, which is a managed switch for $250, not a bad value.
    As for my personal 10G NIC, it's just for video editing. I don't need it for basic daily work, but since I also create tutorials for the team, I'd just centralize everything.
    I'm sort of spoilt with quality network hardware at work, and have been, for 20+ years. Using SOHO quality gear makes me feel as if using no-name asian multimeters with "Class III"  :palm: and "China Export"  :-DD tags on overhead 415V lines. No thanks. Proper 5yo hardware, with RS232 console ports, SSH daemons and double PSUs, freely inherited from work, is much nicer to work with.

    We do a lot of video editing, at work. Lots of 100G links there, and lots of hard drives. Actually, I mostly work with building networks for HD real-time video. A different world.

    My house is run on free second hand cisco gear from work.  All gigabit and all POE.  Not long ago I was able to swap out my sg300 switches for some neat little fan less 10 port 3560cg units.  I have a new rack coming next week so another one will go in that. And I have scored a little Industrial tplink ac access point that will allow me to use external antennas so I have a couple of antennas from a cisco mesh unit that are going up on the roof so me and my whole block will have 802.11ac wifi.

    The joy of free stuff.

    TP-link is SOHO! Yes, I've got a media converter from them. And, we've got them at work, too. They've got the cheapest SFP-equipped media converter around, and it works. But, I'd avoid them for configurable stuff. Because I can  :-DD.

    guys, don't forget to backup your NAS ... 8Tb on a ds218 ... if one drive fails, the whole data is lost. 5 years of hard drive working, it's the average lifespan. if your NAS has built-in test for the drives, use it once a week or once a month. with 4 disks you can have a raid 5 installed so one drive failing is recoverable. but beware. I've seen many customers lost so many datas ...

    And those are offline backups, RAID does NOT count as a backup.

    For a new NAS, at least give FreeNAS with ZFS a look. I use it with mirrored disks, simple and easy. It doesn't require much in the way of hardware for a basic set up (cheap) and is not difficult to use, even for beginners. If you need to complicate your life, it does offer Raid-Z in various types and can scale up to just about any level of complexity you want.

    ZFS is the best file system yet invented. Full stop. Nothing else comes close. I have yet to lose a single file that could be attributed to ZFS malfunction, and I've been running ZFS on things as crazy as 32-bit FreeBSD. (The machine crashed repeatedly, but the files were saved.)

    With 2 drives, you run mirroring (zmirror in ZFS). With 3 drives, you run RAID-5 (raidz1/raidz), and with 4 drives or more, you run RAID6, (raidz2).  It is, given the size of present drives, probably not recommendable to run a RAID5 system today. The rate of failure per stored byte is at a level that with our present drive capacity, the likelyhood of encountering several failures in parallel (before you've hot-swapped a new drive in and it's been resilvered, i.e. taken its share of the load) is so high that double redundancy is required. ZDNet still has a good article  (https://www.zdnet.com/article/why-raid-5-stops-working-in-2009/) on it, old but relevant.  ZFS' integrated data protection measures help, but disk is cheap. Think before you take the plunge.  And cry less.

    Well, not quite today, but I bought a 25 x 25 x 10 mm chunk of Bismuth Germanate to use as a Gamma ray detector.  I already had a setup from a project at work to use a Silicon photomultiplier with scintillators.  So, I put it all together, and it works!  I have a small chunk of the orange-glazed Corelle dinner plate, and I get about 20 counts a second from that.  It doesn't clearly detect the Potassium in a banana, but maybe you need to count for a while to detect that over background.  I still need to tinker with the power supply a bit and make a box for it.

    Not today, but bought myself 2 28" 4k monitors recently.  Been wanting to go 4k for a while, was aiming for 32" but they are so expensive even several years of waiting so for the price of 1 32" I got two 28"!  Was a spur of the moment thing to facilitate working from home.  At work we have 3 4ks and pretty much need most of that space.  I did not want to start having to bring my monitors home then back to work as we still need to take turns to work in the office.  Long story short it led to me splurging to upgrade my setup.

    I originally set it up like this:

    (http://gal.redsquirrel.me/thumbs/lrg-4923-dsc_2078e.jpg) (http://gal.redsquirrel.me/images/other/random/dsc_2078e.jpg)

    Which was great for working from home, with centre one being primary, but not so good for being able to use it for my own personal use, so I switched things around once my monitor arms came in:

    (http://gal.redsquirrel.me/thumbs/lrg-4924-dsc_2089.jpg) (http://gal.redsquirrel.me/images/other/random/dsc_2089.jpg)
     
    A bit of macguyvering going on back there:

    (http://gal.redsquirrel.me/thumbs/lrg-4925-DSC_2087__1_.jpg) (http://gal.redsquirrel.me/images/other/random/DSC_2087 (1).jpg)



    I'm waiting for some DP to HDMI adapters to come in as the ones I have don't have 4k and my KVM needs HDMI, and work PC is DP and so is the secondary output of my GPU, and also waiting for 2 more monitor arms, then I will add the side monitors back.

    Side monitors will be hooked up to a Raspberry PI that will be used for misc stuff like watching movies or whatever.  Basically stuff that I'm not actively working on and just want in the background.  For my work from home setup, one of them will act as the primary for the work PC for my email and so on.

    At this moment the top 4k is running in HD since I'm actually running off DVI but once my adapters come in I can fix all that.

    For anyone bored I did a vlog video on overhauling my setup here (https://www.youtube.com/watch?v=9rzrMq0_Jjs).


    As a side note, more electronics related, I was playing around with Kicad in 4k, and it's awesome all the real estate you have.  I can have an entire PCB visible on the screen and see everything.  Only thing I find zooming and panning is kinda choppy sometimes it flies off to some weird direction.  I'm on Linux Mint 17 which ships with a super old version of Kicad though so hopefully when I upgrade my OS to newer one I will get a newer version of Kicad too.

    I also got a DER-5000 a few months ago and its been a lot of fun. Really couldn't pass it up at the online price. Still have not really learned to use it fully. I also got a Microsoft Kinect, the old kind, for $14 which is also a great deal. It works really well with open source software. Ultimately I want to put it on the end of my 50 foot USB extender cord and map my entire house in 3D. Like a cave.

    The first scratch (burn, in this case?) is always the most painful.  Just juggle your soldering iron for a bit and get it over with - less painful anticipation that way.   ;)

    "It doesn't clearly detect the Potassium in a banana"

    Get a bottle of 100% "no salt" substitute for people on a low salt diet at the grocery store. The potassium 40 in that lights up my NaI detector very well with the 1.46MeV gamma.
    I tried the "lite salt" stuff, presumably 50% NaCl and 50% KCl and was not able to detect a clear change in count rate.
    I didn't put it on a counter and take a couple minute count.  I might try that after I get the thing into a more packaged form.

    Ok. Here are some photos from a few years ago to give you an idea of the expected signal.

    First one is using a program that reads the counts (tics) from the earphone output of an old Geiger detector. Left is background radiation and the step is when I put the "NoSalt" next to it.
    Second is the K40 line from a NaI detector viewed on a Canberra MCA (energy vs counts). About half an hour acquisition time (don't remember accurately by now...It was several years ago.)

    If you cannot see that signal then I would guess a banana will not be doable at this stage.

    I went for 2x 4TB WD Blue. The "bang for buck" or price per kB seems to be best at 4TB at the moment and I also have no idea how I could need more than 8TB.
    4TB WD Blue are ex-Greens. (WD scratched the Greens after that brand tanked, and rebranded them into the Blues. 1TB and smaller Blues are what they was - blues through and through, 3TB and above are ex-Greens, and at 2TB you have both genuine Blues and ex-Greens)

    I'd suggest avoid those ex-Greens, well, for they are Greens after all. The Reds are just much more stabler.

    Well if you ignore the recently discovered mess of Reds undisclosedly using SMR and being buggy/often failing when resilvering arrays. Kinda stupid when they're sold as specifically made for use in arrays.

    I don't use any drive that can not rebuild itself within six hours. Since modern hard drives can do about 1TB continuous write per hour, that means 6TB maximum per drive. This is well before SMR would come in play. My current storage arrays are constructed using 8x 2TB drives and 6x 3TB drives, in a mixed RAID-60 setup across two MegaRAID 9271-8iCC hardware RAID cards.

    No that's the whole point, SMR used to be for large capacities and clearly marketed "for archival", but somehow they decided standard desktop and RAID-spec drives all the way down to 2TB that were previously conventional would now silently become SMRs, under the same branding and at the same price with no notice or any mention/change in advertised specs. They're at best 2x slower on writes than conventional, and cause some arrays to fail to rebuild on them, it runs for a while and aborts because once the CMR cache is full they essentially lock up for extended periods while they rearrange their stuff internally and the systems time out and cancel the rebuild (plus more issues depending on access patterns).

    Saving pennies by removing a platter / pair of heads or 2... and when confronted try to hide/lie behind "we don't mention it becasue these are technical details consumers don't need to know" kind of stuff.

    I _was_ able to force the WD40EFAX to resilver – by switching off write caching and lookahead. This dropped the drive’s write speed to less than 6MB/sec and the resilvering took 8 days instead of the more usual 24 hours. More worryingly, once added, a ZFS SCRUB (RAID integrity check) has yet to successfully complete without that drive producing checksum errors, even after 5 days of trying.

    I could afford to try that test because RAIDZ3 gives me 3 parity stripes, but it’s clear the drive is going to have to come out and the 3 WD Reds returned as unfit for the purpose for which they are marketed.

    It's a total shitshow.

    Seems the other drive manufacturers are doing the same lately but at least haven't denied it like WD did.

    One setting on the voltage range is 1MV.  :wtf: What is that thing?

    In the olden days some US vendors did not fully appreciate that SI units are case significant. milli and Mega must of course be discerned by case. hp was also responsible for such misses on some devices. 

    As to what it is, it is a valve voltmeter or "vacuum tube volt meter", VTVM for short. The classic model everyone else tried to copy is the hp 410b which is much more competent than this Eico. Not that the Eico is bad; the 410b is simply exceptional, with AC measurement up to 700MHz, with DC and resistance ranges to boot. 

    Why was there such a focus on them being valve voltmeters? Well, for starters, the only electronic amplifier available was the valve. Very early VTVMs started appearing in the 30s, and were perfected in the early 50s. And, with the alternative being electromechanical meters like the Avometer or the Simpson, where, even in those quality instruments, there is a low resistance in the meter (affecting the DUT and the reading) and bad AC frequency response (most likely not above 20KHz, and even that was a stretch) it obviously was important to point out things like a DCV resistance in the range of 10MΩ and AC response up into UHF.

    I've wanted one since I read the service instructions for 60s HiFi gear stating "you need a VTVM to get this right, don't try it with a purely mechanical instrument". As a consequence, a lot of gear was shipped with service manuals that said "if you're using an Avometer 8, this is the value you should be seeing at test point 46"

    You can get a cheap one like the Heathkit VTVM for perhaps $50, with lots of variation in price.  I've got an ex MoD Marconi. Temperamental, but works.

    HP410C is my favourite!
    We used them, back in the day, along with the hp coaxial sampler to measure power on lower power TV transmitters, using V^2/R.

    The good thing was that the probe was a "sample & hold" type, so we could read the RMS value of the "sync tip" voltage, & directly calculate "sync tip power", as that was what the specification for vision/aural power was specified w.r. t.

    I picked one up a couple of years ago at a Hamfest--- the "ac zero" pot was jammed, but a bit of "working " of it back & forth cleared the problem.

    As is common with old ones like this, the centre spike from the DC probe is missing, but everything else works well, now.

    As to using an AVO 8, both Tektronix & Marconi often built in voltage dividers to a test point, so that critical voltages could be checked with an AVO, Simpson, or similar VOMs.

    A.T.E. tube type VHF point to point Radio links provided special test points so that grid & anode currents could be read with an AVO 8.

    All good, except if you are trying to "peak the grid & dip the plate" at a minesite, where the primary function of the power station was to power an enormous machine which, every time it dug into the ore face caused the Mains to dip alarmingly.
    You would be just approaching an anode dip, when the lights would suddenly dip, & the AVO would go crazy!

    We had Stabilacs, but the voltage drop was too severe & too fast for them to handle.

    I've been collecting gear for almost this exact setup for a while!

    I was able to manually do gamma spectroscopy with a single-channel analyzer and a lot of spare time.

    I recently got both Ortec counters, their RS232/GPIB interface, the single-channel analyzer, a 7-decade scaler and a Canberra delay amplifier for way too much, but I'm having too much fun to care!

    The attached spectrum is from around 100g potassium carbonate. I also did a video on it, but my setup has evolved quite a bit since.

    You really should be able to see a count rate difference, even with a normal geiger counter for a decent potassium source, though!

    Ordered a 300mm × 100mm × 10mm block of 6063 aluminium.  Shipping and handling was three times the price of the material itself :-[.

    No local metal suppliers? Its a normal extruded sheet right.

    Bog-standard 300mm cut from a 6m long EN AW-6063 T6 100mm×10mm extrusion (about 12" of 4"×3/8"), yes.  No, I know of no local metal suppliers in or near Helsinki, that would bother to sell such offcuts to hobbyists like me.  Hafta order from Oulu..  but all told, it was under 20€ (about 21 USD) total, so I'm not complaining too much.

    Not directly electronic, but...

    A 3/8in drive digital torque-angle wrench with a range of 5-100 ft-lbs. Does tracking, peak hold, 10 memories, presets for torque and/or angles, converts to all metric and imperial units, etc. We're doing a bunch of development using various kinds of motors to drive various kinds of loads and in some cases (particularly hydraulics), knowing the load's torque is extremely important. Everyone's existing torque wrenches went up to 250+ ft-lbs because they bought them for working on vehicles, but we're dealing with much smaller values and most torque wrenches aren't accurate in the bottom 20% of their range.

    I personally already owned a very small, torsion bar style 1/4in drive torque wrench that reads in in-lbs but its range was too low. Also, difficult to read accurate values from their scale-and-needle "displays".

    I've never before seen a torque wrench that also measures angles of rotation. Apparently some fasteners are tightened that way. You set them to a certain position or a certain torque, and then rotate them a prescribed number of degrees past that point. Very interesting.

    This thread, and Bad Obsession Motorsport for me.  I hope Nik would be proud: I needed this material for a bracket.  (I need the 10mm thickness for a 3mm grub screw.  No mill, you see.)

    I am seriously hankering for a Proxxon MF 70 micro mill.  I could do so many brackets, heatsinks and custom enclosure modifications, and brackets for my Linux SBCs and microcontroller projects (Teensy 4.0 overclocking heatsink maybe?).  Only, getting one would run me dry (I'm broke), and then get me evicted due to noise, as I live in an apartment.  Eh, might have to risk it: I don't like my neighbors much anyway.

    Not at all uncommon in modern mechanical equipment. Cylinder head bolts are often single use and the degrees of rotation beyond a specified torque is to apply the correct amount of bolt 'stretch' tension.

    It's mostly due to aluminum being used more. I've never bothered buying one but I used a "manual" angle gauge with my 1/4", 3/8", 1/2" and 3/4" torque wrenches. Even the top of the line wrenches are cheap now. My 3/8" and 1/2" were about $1200 when I bought them, some of the first digital snap-on wrenches..

    You bought the wrong card. There are two different cores for the RTX 2060: the original RTX 2060 based on TU106, and a newer version based on TU104 that failed to qualify as RTX 2070. While nVidia did turn off features on those failed TU104 to align with TU106 in terms of game feature, a lot of non-game features are left on for whatever reason. Those RTX 2060 TU104 cards can perform close to an RTX 2080 levels when coming to non-gaming tasks like non-real-time rendering, compute and ML.

    Yeah, I bought the wrong card. I was looking for Tesla V100S, but strangely I can’t find one in a budget of few hundred dollars.

    As for the RTX 2060 Super - it is definitely better for ML than its non-Super siblings both the new (TU104-based) and the old (TU106-based) ones. Significant differences: 2060S has more memory (can train in larger batches), wider memory bus, larger L2 cache. Marginal differences: slightly faster performance (in TFLOPS) due to 2060S having somewhat larger number of CUDA cores and tensor cores that run at slightly faster clock.

    Nice buy.
    Some of these older motors are easy to repair and have standard bearings. In my experience buying older shop equipment (grinder, lathe, drill press, bandsaws, etc..) is once properly repaired is they will outlast the cheap/regular stuff.

    Looking at what seems to be embedded metal on the wheels I would invest in a dressing tool and check balance properly before putting it to use. Also a good pair of safety glasses or a full face shield of course.

    Benchmarks says otherwise if folks at Gamer Nexus are to be trusted. They have benchmarked the 2060 TU104 against both 2060 Super and 2080, finding the 2060 TU104 leaning very close to 2080 when running their suite of non-gaming tests. The key here is that other than spec sheet, there are more design differences in the TU104 and TU106 cores, some of them that is not reflected in the spec sheets, yet so fundamental that nVidia can not turn those off when binning the chips down. Something like improved FP64 handling, a better tensor core/RT core design, even physically spreading the cores out more so heat transfer can work better.

    How does AMD bode now with ML? There are folks now buying retired mining rigs loaded with RX 470 and RX 480 for ML tasks.

    A genuine INTEL I350-T4 QUAD is hard to come by, as China is flooding fakes out.
    The OEM's (DELL / Lenovo etc...) , are less hit (yet)

    A good hint to a genuine is that the DELTA xformers must have the DELTA engraved into the plastic

Now I have a known good Zigbee Light Link target, time to cook up that AT86RF231-based ZigBee module, either as a Pi HAT or a USB dongle.

    I got this GE Talaria MP projector some time ago but was not able to access it because of COVID-19. I think this projector was built around 1997, has a resolution of 1024x1280 (I guess they mean 1280x1024 but it is written the other way around in the documentation?!) and 8000 lumens.

    Unfortunately all boards do have a ton of tantalum capacitors on them and one started to burn when i started the projector  :-BROKE

    I've replaced the capacitor but i guess the next one will blow on the next try to power it up. I have the service manual with all schematics and a box with some spare parts for this thing.

    Don't forget, this thing has 8000 lumens, after a quick search a modern 10000 lumen laser DLP projector seems to use about 1300w, i did not find one with 8000 lumen, the Talaria is rated for 1750w. I left the service manual with the projector and do not have it at home, i think the lamp is rated for 1000w and the heating for the oil inside the tube seems to use a ton of energy too...

    Nice, I found a good cheat for avoiding customs import duties for my customers in the EU/UK - I declare the products as "commercial samples" and the description as "prototype adapters". Luckily as my products are all hand soldered using TH parts and they use Prototype HASL PCB's, if customs were to inspect the goods they'll not find any reason to disagree.  8)

    A SoftRock Ensemble III Rx Kit, a few toroids to wind and some SMD, nothing too nasty. I am interested to compare it to my HPSDR (Atlas, Mercury, etc).
    It was a fun kit to build, I have the transceiver kit started but have been too busy to get back to it. (all boxed up and the printed manual in the book case). It works okay, the receiver does about a microvolt for 6DB SNNR, It is certainly usable. It wasn't a hard kit to build although, if your eyesight is worse than my eyesight (20/300) you might want to get someone to build it for you. :) A lot different than that Heath SB-301 I built back in 72.

    I don't think that i saw RIFAs when i opened mine, but i didn't really search the PCBs for them either. One thing you should do is to check the 2W 5.6 Ohm power resistors that are between the two secondary transformers and the positive/negative output, those tend to get cooked when someone connects a low resistance load (the 2W resistors are in series with the output). Happened to one of mine, a (ebay) buyer thought that electrophoresis and electrolysis meant the same thing and complained why his electrolysis cell wasn't working... Go figure.

    As someone who takes their Coffee more than a little seriously  ;D The little Burr Grinder would be the pick of them unless you are making Turkish style coffee and it won't grind fine enough for that. Also consider a small modern hand grinder if it is just for yourself Hario or Kyocera make really good ones.

    Prismsound DScope III audio measurement set.

    Been after one for ages, superb bit of kit for what it does (The AP has a slightly better generator, but the DScope software is IMHO much more usable).

    Prismsound DScope III audio measurement set.

    Very nice, I've wanted one for ages but it is far too expensive for mere hobbyist use, so I had to settle with the old Japanese analysers instead (Panasonic and ShibaSoku). I only needed quick and dirty THD+N measurements so it's more than enough for me.

    Curious as to what the typical generator/analyser performance is because the spec is -108dB THD+N and at that level, I think it's just running straight into an ADC instead of notching and processing, right? (like the higher end AP or the traditional analysers from Japan)
    Title: Re: What did you buy today? Post your latest purchase!
    Post by: dmills on June 04, 2020, 10:14:52 am
    The generator is actually the weak point, +4dBu 1kHz is showing about -104dB THD+N and yea I think it just does the ADC thing, but it is also a faction of the cost of a fully tricked out APx552.
    It needs to go off to Prism for cal and a tune up.

    I mainly wanted the multi tone IMD stuff, usually more important then THD once you get to this sort of level.

    I do wonder if the smart way to do a modern THD set is not to use a two channel DAC as the generator and sum one of the channels into the signal returned by the DUT, then the software can adjust that side of the generator to null the fundamental by some sort of LMS loop.
    Some of the modern AKM parts spec that you can build 23 ENOB DACs and other such wonders, but we all know how tricky that sort of thing can be in reality.

    I mean it is not like ANY loudspeaker is going to manage that at significant power (-60 is a stretch for most of 'em), and transducers are the only really interesting bit of audio these days.

    I'm pretty sure that the Audiofools will see that differently. First you need to make sure that your IEC plugs are gold plated, then you need to balance the cable on teak wood bridges so that they don't just lie on the floor. Then comes the copper that needs to have been extruded in the correct direction so that the electrons flow best and we haven't even started on the capacitors made from unicorn tears by naked virgins. Obviously none of this is measurable with the insufficient equipment that we "non-believers" use, but the "trained ear" will notice an obvious improvement in (add some non-defined unit of clarity, dynamic vibrance or whatever here).

    Don't forget that cryo-treating everything will improve the sound noticeably (though immeasurably - our stupid instruments are no match for a golden ear!), too - make the highs higher, the lows lower and expand the soundscape.  I'm surprised none of them have advocated getting a dewar full of liquid nitrogen and spraying it on the walls and furniture to cryo treat the room!  (Perhaps we should suggest they dip their heads into LN2 to cryo treat their ears!)

    It never ceases to amaze me that these people will swear that their insanely high end system sounds /noticeably/ better with the addition of a $2500 AC mains cable to power their CD player.  If your system is nearly perfect, then how can it sound noticeably better?  And if it can sound noticeably better, then it must be far from perfect.  Making an almost perfect thing noticeably better sounds rather contradictory to me.  (But then again, I probably have a tin ear and can't hear the increased lushness that adding expensive little holographic stickers to the ICs and capacitors in my equipment can provide.  I'm such an acoustic philistine!)

    Nope, you cryo your ears by entering your listening room, closing the door, putting on a classic recording, then taking a 250L dewar of LN2, close the windows and spray the lot around the room!

    Hint, consider how much atmosphere will be displaced as 250L N2(l) turns into N2(g) and warms to room temperature.....

    Yep. Frightens the life out of those audiophools.  >:D
    Because doing room acoustics requires real knowledge, experience and the right measuring equipment for frequency decay time measurements and room nodes. And you need a lot of time. But that's  :horse:

    Prismsound DScope III audio measurement set.

    Been after one for ages, superb bit of kit for what it does (The AP has a slightly better generator, but the DScope software is IMHO much more usable).

    All good things come to ebay if you wait long enough.

    Utter, thorough, long-lasting envy. Congratulations.

    Bought a "broken" Asus MemoPad HD10 for €20 to use as a screen on my Andonstar microscope. The supposed broken bit is the wlan, but it's not broken, WPA_suppliment_conf is just corrupted. Now in the process of rooting it so that I can swap the file and get wlan running again.

    Oh I am sure I can build a better THD setup, even a much better THD setup, but 100+dB down for audio, do I care?

    I mean it is not like ANY loudspeaker is going to manage that at significant power (-60 is a stretch for most of 'em), and transducers are the only really interesting bit of audio these days.

    Regards, Dan.

    Fully agree. One puts the money and effort in electromechanical transducers. It is the hardest, most challenging piece of the chain, whereas the rest is solved for most practical purposes today, especially so if you're able to have a completely file/stream-based delivery chain.  Consequently, I've got a SL1000 record player in radio kit-out (wheel undercarriage, RIAA with balanced output, local monitor speaker, fader start, 78RPM option, wiring loom with DIN 41622 Messerleiste, etc) and active monitors made by swedish company Audio-Pro back when they did good things.

    Let me guess, 1/2 rack PTP generator, box made from stainless steel for some weird reason?
    That will be because the software is ropy as fuck!

    And Sonifex well know it, we found ours made better PTP when we unplugged the GPS then it ever did with it plugged in (Idiot thing would re do the PTP master election every time the number of satellites changed, turned out this annoys Embrionix kit).

    It's been a very interesting couple of months here in NZ and towards the end of our Covid lockdown sales jumped I think as hobbyists found their old gear not up to their requirements after having the lockdown time to really get on and use it.
    Lately, now small business can see the light of day again and they also have had time to consider their projects and futures, sales to them have also jumped as they now have a lot more confidence.
    The next year or so will be interesting.  :popcorn:

    Still, the whole of NZ is a quite small marketplace of just 5M that I can cover with just me and her......smaller than many cities around the globe but way more spread out so I get very few buyers calling in person which is a little sad as I really enjoy discussing what they are doing.

    Oh, yeah. The single thing we're using Sonifex clocks for is to lock on to Wordclock, because that's not a thing our Meinberg does. Yesterday we had the final sync ( :-DD) meeting on the new clock infra. When the old BB/Tri-Level gens we've got are EOL (like two years ago...) we're buying another Meinberg and two Tek SPG that'll be steered from the Meinbergs. Order goes in next week, IIRC.

    Since the beginning of this crazyness I always expected a boom due to the suppressed demand. The isolation may have left more money in the pockets of people (at least the ones that still have a job).

    The million dollar skill is to perfectly sense the new demand boom, so you don't end up with excess inventory. :-+

    Though I don't like Adobe's business practices, I can't deny it's still the industry standard. I've heard good things about Affinity Photo being an alternative and considering they now have a 50% Covid discount, I thought I'd give it a go. I was prepared for some frustrations and issues as all alternative software tends to have, but am surprised to find I can just jump right in and get on with things. It's not just good enough to avoid having to deal with Adobe, it's actually good. I've spent a few days opening and editing my existing files and exporting them back and forth, putting it through it's paces and it consistently managed to impress me. I like to so much I've now also bought their other apps. It's essentially just Photoshop with small but worthwhile enhancements, except without the cloud and subscription nonsense. At around $30 it currently is an absolute steal. Even their terms and conditions are very reasonable as you can install the programs on as many of your personal computers as you like. Bye bye Adobe!

    The Keysight M9260A I picked up for 3 grands, after some cleaning, ADC/DAC binning and aging, achieved -122dB best case loopback THD and worst case (with sensible amplitude) THD of no worse than -118dB.
    With its default ADC/DAC, it still works better than its paper specs, and my tweaking only improved it by around 2dB on average. What's mot important is I made its two channels more symmetric, which only serves to satisfy my OCD.

    Thanks for sharing, I've always wondered how those perform! -122dB THD is still limited by the ADC and is just about what the best can manage without notching, do you remember off hand the typical THD+N performance?

    The old ShibaSoku am51 will do -130dB THD easy, about -111dB THD+N mainly hampered by the ancient venerable 5532 opamps. The older ShibaSoku 725 can go down to -120dB THD+N with some basic mods (opamp swaps and fixing some ground paths).

    After months of searching I've finally found and set up a Cisco 3802 access point. Fulfilled a lifelong dream to get wifi to max out the gigabit ethernet cable (using a cheap Intel AX200 wifi adaptor).  :P
    I know I know wired is still king, but I'm too scared to crawl under the house and route some ethernet cables.

I'm not wasting more in a better gen for just a single use. I think I'll have some fun modding it to make it less crappy, 'though I've not yet found a schematic for this beast. Anyone?

    Interesting... I started burning EPROM's around 1980 (2716's and the like). On a 9600 baud connection the full 16K would download in under 15 seconds, considered acceptable in those days. Actually burning took a bit longer. {grin} Can't say I've ever seen a parallel interface EPROM programmer, though I'm sure they existed.

    Ever used a National Semi Starplex development system? It was their answer to Intel's MDS "blue box". On the right side of the console there was a big square area where you could insert an EPROM programming module. Had a nice lever-operated ZIF socket and everything. I started using one of those in about 1981. The cool part, for me, was that at my next job I was the only guy who knew how to use a Starplex - somehow National had convinced that employer to buy one - which meant I basically had a whole development system to myself and didn't have to jockey for access to one of the very few, very expensive Intel MDS's in the lab. I had a dedicated development system, emulator, and EPROM programmer all to myself.

    It sat a month and a half at Senzhen Processing Center, then almost a month at the Senzhen Interchange Bureau before being delivered to the airline.  After two weeks, it arrived in Finland, and on the third day plopped into my mailbox.

    BuyDisplay does now warn that "We temporarily canceled the shipment service of ePacket, EMS, China Post because overbooked. Only DHL or FedEx is available now. Our ebay store still keeps the economy shipping." though.

    An old Anayak FV-2V Mill.

    [attachimg=1]

    Not electronics, but a nice price.  Achieving a long term ambition to own something like this.
    Still have to move it, so all current projects are dropped till that is done.
    The actual moving is fairly easy, but making a space for it here first is more difficult. It's HUGE.

    This was totally unexpected. A result of a casual conversation while buying a small tube of rubber glue, related to repair of that pressure regulator for the spot welder.

    Incidentally, if anyone in Sydney needs a giant flywheel punch, or a huge surface grinding machine, or an enormous hydraulic press, all for stupid cheap prices, let me know. The factory that sold me the Mill is also disposing of those. But you'd have to arrange your own transport.

    Yes. Minor problems, including a bad bearing in the head (for which a new replacement came with it.)
    Also came with it: a Sony LH51 3-axis digital readout and sensors. Works but needs cleaning.

    This Mill was generally used by the previous owner to machine fiberglass blocks. So all the visible dust is fiberglass powder. Vacuuming that off and disposing of it will be chore #1.  I already discovered what happens when you get that stuff on your hands.


    Getting this Mill set up is now on top of _another_ recent unplanned acquisition. A Hendey lathe, possibly built around 1895. Which I did not need (already have a much bigger and better lathe), but the Hendey was free, and if I didn't take it, it would have been scrapped. Deceased estate, house being sold, lathe too difficult (for others) to move out of a rear shed. Not yet sure if I'll sell it or what.  This (in its original home):

    [attachimg=1]

    Anyway, it's all good. Forcing me to evict a pile of antique computing gear from my 'still under construction' workshop space. Which had totally wedged that build project. They are going to alternative storage spaces elsewhere, and so my workshop build project is resuscitated.

    If I can get it to work it might end up being the only programmer I need.
    You can still download it on the bp website but if it has a parallel port like my bp-1600 then you can only run the latest version for windows XP, believe v5.33 since the windows versions after that do not support the lpt port anymore and the software requires the newer version programmer with usb port.
    You can also go for the dosversion, latest was 3.71.

    The programmer is very nice but the drawback is that you need a special adapter for each unique parthousing and those adapters are ludicrous expensive.
    A simple coversion pcb such as with the chinese programmers will not work.
    Each adapter has data address decoders en switches on it and a unique i2c eeprom that identifies the adapter to the programmer.
    I still hope someone will provide the i2c rom codes and gerbers for the pcb for this someday.

    Four years ago the source for the software was the following, not sure if it is still operational:

    Little update on these, a few months later: wow. The precision of the PB Swiss tips puts others to shame. These are just a joy to use.

    Similarly, the Mitutoyo has proven itself too.

    This 24V 10A Din Rail model has gone EOL but they are a steal
    Not bad if they were new original price: €50
    But these are used.
    I bought some MW second hand 240W 24V lately used in a led project for two years for €10 a piece, but not din rail.


    10 Pommie Pounds is nearly $20AUD plus a bit of postage. Currently listed on Mouser at $120 AUD+tax and E14 at $150. $40 AUpesos delivered locally is cheap.

    Coronavirus quarantine haul:

    1. Knipex flush diagonal end cutters
    2. Erem super full flush side cutters
    3. Wiha ESD safe chip lifter
    4. iFixit Mako (4mm bit) screwdriver kit. The handle on this is fantastic. I’m going to get the 1/4” handle of theirs, as AFAIK, it’s the only 1/4” bit handle with a precision screwdriver style rotating end cap. (And on these, they have ball bearings!) That handle with PB Swiss bits is going to be an unbeatable combination.
    5. Wiha/Xiaomi driver set (also 4mm). I love this, too. Better bit quality than iFixit, handle is a great precision driver.
    6. The Sony amp and CD player I’ve been looking for for years. The CD player is easy enough to find, but the amp is quite rare. I doubt they sold too many of them. (The TA-FB930R and CDP-XB740, for those who care.)
    7. Genuine TE Ampmodu MOD IV crimp tool, which with one guard piece removed works great for generic DuPont and Molex KK254-type contacts. Snatched this for under $60 NOS!
    8. The pièce de résistance: a Pace desoldering station (ST-75 with SX-90 handpiece) for $115 shipped, including 25 sets of filters, spare tubes, and 6 new tips. It was rather dirty, and the handpiece needs some TLC (the button keycap had broken off — I fixed it by melting some copper braid into both sides to give it a new “hinge”, it needs new rubber seals, and maaaaybe could use a fresh heater, but even if I bought all that it’d still be a steal!) As you can see, it cleaned up nicely! It works great, far better than the Weller at work. I do need to get a tip assortment, as all the includes tips are the same size. Anyhow, given their reputation, I had high expectations for the build quality of this, but it’s actually even better than I expected.

    ...but if it has a parallel port like my bp-1600 then you can only run the latest version for windows XP, believe v5.33 since the windows versions after that do not support the lpt port anymore and the software requires the newer version programmer with usb port.
    You can also go for the dosversion, latest was 3.71.
    It seems to have a parallel port so maybe it is not worth the effort.  I did download bpw_v4730 earlier... seems to be a VB app with a big database.... unfortunately I don't have VB reversing skills so it might be a bit intractable.

    Those are not as corrosion resist as real stainless tool steel (like real CrV or tungsten steel) ones.
    Mine was perfectly fine for the first two years when I used them properly with the aluminum handle.
    A few days ago I tightened a few screws with my sweaty bare fingers, and the bits started showing rusts the next day.

    And also stay away from Xiaomi's WowStick, they ship with even worse bits, so bad they they are softer than some quality screws.
    Now I'm looking for tungsten steel screwdriver bits, I wonder where to get some. I'll skip CrV as so many fake CrV or real CrV with bad tempering is out there.
    Needless to say, I'm more than happy with my Victorinox's included Philips screwdriver. I just wish they are available in 4mm hex form factor at any cost.
    Wow, that’s surprising!

    Unfortunately PB Swiss doesn’t make 4mm hex bits. Otherwise I’d be all over that. If you’re talking about normal 6.3mm bits, I highly suggest trying the PB Swiss. I have no idea what their alloy is, but the precision of the grind is superb, and by all accounts PB Swiss drivers and bits last a long time. The bits have got some kind of surface treatment (anodizing?) with the steel (!) of the whole bit color-coded by driver type. I have no idea whether it helps against corrosion. I haven’t had mine long enough to test corrosion resistance.

    A "new" portable and quiet computer (refurbished):

    Pretty good configuration for its age: Full HD display, 512G SSD, 8GB RAM, i7-4765T. Fits perfectly my Dell docking stations (that I've saved from the dumpster @work), and therefore easily swapped with the Precision M4800 that I'm using ATM as the main PC.

    Yes, it has:

    [attachimg=1]

    Both computers (the M4800 and this E7440) support dual monitors on the dock plus the internal screen, so my triple screen setup works too.
    After some debian install-fu (apt-clone and rsync of home directory) the E7440 now is a perfect clone of the M4800, just slower at multi-threaded compile jobs (say make -j 8 ). It's greatest advantage over the M4800 is the fan isn't running at normal active linux desktop, while the M4800 gets quite noisy even when idle.

    I have three seperate ssds , win10, win7 and win xp and just place the one I need, only make sure the internet is disconnected so hackers cant corrupt the no longer updated os's and you have a great and compact solution to support old equipment.

    That kit is a wonderful upgrade to the other lots-of-crazy-heads driver kit that's part of their tool kits. We've got both, and the Mako is property of my wife, stored in her tool chest. But I'm allowed to borrow it.

    Wiha is also a favourite. I've got a few of their torque screwdrivers, and a nearly full set of the standard red/black screw drivers, including the largest slotted DIN has published a standards sheet for, 14,5 x 2 mm.

    Oh, and I've been active recently, too:

    "Possibly working" was the sellers verdict. It has one of the sick (small, circular, same as old Quad 303 amps, IIRC) Bulgin mains inlet connectors, so I'll have to source one.

    You can do all the configuration without an SD card as far as I can remember. The card option is really only there to save time when you need to set multiple units to the same settings.

    I bought another 16GB DDR4 module to bring my system to 48GB...

    ... and Amazon sent me two packages, each with 16GB within.  I contacted their cust. services, and was told to keep the extra.

    So now I have 64GB of RAM.  It is more than anyone could reasonably need for a desktop system.  I originally upgraded from 32GB when I moved to a Ryzen 7, as during large FPGA builds I was getting memory allocation failures (often bumping on 28-29GB of usage.)  But I doubt I will ever begin to use this allocation. At least the OS can use it for caching.  I wonder if I can force Windows' caching policy to be more aggressive, often it leaves >20GB unallocated.

    (Micro) SD cards can be SD, SDHC, or SDXC. I don’t know whether the nano supports SDHC or SDXC, that could be the issue. I can check once I’m at home.

    Thx Tooki. The guy at Ersa didn't mention the type of the SD card. He just told me to verify the version of the software and to try to insert the card several times... I'll really appreciate if you could confirm that this is the problem, and after that the challenge will be to find a non-HC or XC micro-card, as there are no more on the market!

    PS: on the Ersa website, they say 2-16 GB formatted FAT8, 16 or 32. SD are limited to 2GB and FAT16, so SDHC should be supported...

    The card I bought for my nano appears to be a 4GB Samsung SDHC, formatted as FAT32 with MBR partitioning. Based on the disk name, I suspect I temporarily borrowed it to test a handheld audio recorder, so it was likely formatted in that device.

    Yeah, I don’t deal with SD enough to know the size brackets by heart. (As for the file system, you certainly can use a newer file system on a smaller SD card, or a non-FAT filesystem altogether. I mean, it won’t work on almost any gadget, but computers can handle it just fine! :p An SD card makes for a nifty portable boot disk for computer troubleshooting, albeit a generally slow one!) I vaguely recall there being a period where some sizes of SD cards existed in both the older and newer hardware types, such that incompatibility sometimes occurred.

    Do you have the TS80? If you are happy with TS100, I think TS80 won't fail you. It just added some new tips into its selection, including a nice knife tip and a bend long conical tip.

    No, didn't know of the TS80, so had to look at Dave's video. Yeah, I can see why. Definitely want.

    I don't think Windows would ever do much caching at all for a desktop-ish machine. On my dual socket machine with 128GB RAM and Windows 10 Pro for Workstations, it uses just about as much space for cache as yours do. And this is already a server-ish machine with a supposed Windows Server derived kernel.

I already have a HP4070C smd tweezers and a DE-5000 LCR meter, but I've been watching this Mastech MS8911 as an alternative to measure components on the board without have to de-solder them.

    My latest purchase is the Rigol DS1054Z scope last month. After wanting a scope since I was a teen, at 40 I finally own a scope. Sure its not as fancy as a lot of the other ones but after seeing Dave's video on the DS1054, and its "options" it was a no-brainer especially at $370 shipped. I haven't really done anything fancy with it besides clipping to a few things here and there to "learn" the functions.

    My latest purchase is the Rigol DS1054Z scope last month. After wanting a scope since I was a teen, at 40 I finally own a scope. Sure its not as fancy as a lot of the other ones but after seeing Dave's video on the DS1054, and its "options" it was a no-brainer especially at $370 shipped. I haven't really done anything fancy with it besides clipping to a few things here and there to "learn" the functions.

    Congrats on your first scope! Have fun!

    Getting your first scope is like losing your virginity. You never forget your first!

    The 1054 is a fine choice. You'll learn a LOT and have fun in the process. Just be forewarned, scopes can be addictive. You'll find yourself rationalizing all sorts of "reasons" why you need another, or one with more bandwidth, or deeper memory, or 10-12 bit A/D's, or a larger screen, or....

    Welcome to the lifestyle!  :-+

    This is a lot of a wideband receiver in a compact package:
    FM (stereo), LW, MW, SW, SSB, AIR, AM-SYNC (that works!), scanner, narrow and wide band, dual conversion, 2000 memories...

    Love it!

    That was a day 0 thing. ;) Pretty much everything else was unlocked & official when I first powered it on so the only thing I wanted was the 100Mhz option, not that I *need* 100, but I sure as heck wasn't going to say 'no' especially considering Dave's teardown shown the front end could do 100. I use duckduck though. :)

    I have had this tester for a few weeks:

    https://www.amazon.com/Testers-KJ-KayJI-Multimeter-Capacity-Temperature/dp/B07X3HST7V/ref=sr_1_2?dchild=1&keywords=usb+c+tester%2Ckj&qid=1594286016&sr=8-2 (https://www.amazon.com/Testers-KJ-KayJI-Multimeter-Capacity-Temperature/dp/B07X3HST7V/ref=sr_1_2?dchild=1&keywords=usb+c+tester%2Ckj&qid=1594286016&sr=8-2)

    Then when re-writing the manual to be able to get more out of it, I realised it is pretty much a power monitor for anything.  Not only that, but it can be used to make up any kind of USB adaptor lead.  So to make it as flexible as possible for monitoring and plug/socket conversions, I bought these yeaterday:

    and

    Set of USB converter/adapters - 10pc for about $5.  Took 10 weeks to arrive Being aware that some cables, and possibly some adpators, don't connect all the wires through the first thing I did was try to connect a mouse through various combinations of adapters - not a complete test, but I would assume that if all four standard wires were not connected I would get some sort of error (certainly did get an error on a known "charging only" lead in my bag).  All adapters worked.  So link for those foolish enough to chance $5 on a delivery taking 10 weeks: https://www.aliexpress.com/item/32874895044.html?spm=a2g0s.12269583.0.0.6cbf52dfuZUPyH (https://www.aliexpress.com/item/32874895044.html?spm=a2g0s.12269583.0.0.6cbf52dfuZUPyH)

    Poor Man's high voltage impulse generator.  For EMI/EMC testing - if your board is susceptible, I promise this will knock it over.  Normally your testing would involve spiking to the metalwork - but if you were designing for reliability you might have specific I/O connections you wanted to Direct-Inject test into.  The lug on the side of the push switch goes to the metalwork (ie It is the return).  The unit comes with a probe.  But it really can kill just about anything electronic, so you need to be pretty sure you know what you are doing before using it.  About $5, and takes about 10 weeks to arrive (or choose a faster shpping option).

    I am sorry but you are mixing apples and pears. That piezo element is surge generator -  industrial testing according to EN 61000-4-5. "Direct-Inject" (not correct term, is used for RF coupling to wires via injecting clamps, according to IEC 61000-4-6) test is ALWAYS with some coupling element ( EN61000-4-5 , chapter 6.3), with series resistance and parallel capacitance.  It is absolutely necessary to keep in correct terminology in EMC. You are NOT testing your device for surges by spiking to metalwork. For that is ESD gun, completely different test and different methodology. 

    You might mean that piezo element is burst generator, but definitely is not.  Please, use correct terms or you will mislead others.

    The 59250 is on the top/right, I like that it can do both sizes of my old tools (47386/47387) and it's a bit more compact to boot. The closer handle distance means it's a bit easier to squeeze/grip with my girly hands but the actual force seeeems to be about the same as the others.

    Looks to be working just fine but I'll have to do some DIY tensile strength testing later. For my home hobbyist use I think it's more than adequate, a quick test shows that I have no chance of pulling a crimp terminal off a wire with my hands (the spec for 16awg wire was something like 20kg force from memory).

    I got myself a laser "pointer": A 270W 915+980 nm diode laser for a price that was probably below scrap metal value (guys, don't ever start ebay auctions at 1€... [unless it's for stuff that i want, then it's perfectly fine]).
    Not quite sure what i'll do with it, as it was purchased because of cheap and not because of need. I'll probably take it apart and sell the optics as i do not plan on using a laser that requires 50A@25V (good luck trying to find a power supply for that thing).

    And of course it's not any old diode laser: This is a made in germany, no expense spared machine. Just take a look at the top cover, it looks suspiciously like someone took a 40x40cm aluminum chunk and removed roughly 90% of the material... The aluminum alone will set you back nearly 100 backs.

    @jogri 25V 50A is not that difficult. If you have 3phase power supply at you house you can try Simens SITOP40 PLC power supply.
    I found this version cheap on ebay, although used, quality is perfect.
    Can you give us more pictures of this masterpiece? Especially driver board that can handle 50A?

    Here are some more pictures/comments about my laser:

    -it doesn't have a driver board, they simply use two pairs of massive copper(?) bars, the eigth individual diode bars (per wavelength) are wired in series. Switching is done via a transistor (blue arrow) on the positive side, other than this, a cap against ripple and a hall effect sensor to measure the current there's nothing directly connected to the input terminals

    -it claims to be able to tolerate 250 mA ripple current (well, even the ripple current could power a nice laser), it looks like they just connected the input terminals to a big capacitor (the blue thing zip-tied to a diode bar)

    -it can provide you three different wavelengths: one >1 mW 635 nm alignment laser (orange arrow) and two 915 and 980 nm diode arrays with 135 W each (i guess, it just states 270 W total). The entire setup you see on the pictures is duplicated on the bottom level, probably the array for the other wavelength

    -each one of the four blocks contains two diode arrays, the beams get combined, pass a semi-transparent mirror with a power meter behind it (top left corner), pass a tilted lens(top middle, the large brass plate), go through a few dichroics and get combined with the other wavelength beam. They probably use another dichroic to get the 635 nm beam into the main beam

    -nothing quite says "serious laser" like a watercooled(!!) fibre... Yes, those two blue hoses are there to cool the optical fibre. Why do i get the feeling that such a fibre assembly will probably cost more than my entire home lab?

    -i still don't know the exact specs of this beasts as manuals are just non-existent. Judging from the model number (Optotools 270-30) and other lasers from the same company it seems like it's a 270 W, 30 mm mrad laser

    -they "might" have overdone the thermal mass: Even though it is just 40x40x20 cm small it weighs 40kg... Well, at least it won't get toppled over accidentally

    -i found this link to a evilbay offer for a similar laser from the same company: It just has one level so you can see the individual components more clearly:
    https://www.ebay.com/itm/OPTOTOOLS-nlight-high-power-diode-laser-OTF-200-20-IP-DSO/174302584669 (https://www.ebay.com/itm/OPTOTOOLS-nlight-high-power-diode-laser-OTF-200-20-IP-DSO/174302584669)

    Ah that looks familiar, I also have one of those.
    Is this one fully working as per front so 0-45V and 0-70A on 400V three phase power?
    I ask since mine is one of many coming from a dutch company and seeing the 12NC dutch company sticker on the front I suspect the same.
    Delta modified them in a special way so it does not act as the original design.
    Mine is more like 0-60V and 0-45A strange behaviour in a fixed power configuration.
    Via via I have gotten the reverse modification instructions so if interested contact me. I have still to do the modifications myself  :)

    Yes, its of the same kind. Voltage can be brought up to 90V, short circuit current limit is somewhat above 70A, and above 50V it acts strangely. As you said like limited power. From what I've observed, it isn't fixed max. power, but rather appears to be limited by the max. duty cycle of the converter.

    Some time ago, I had a talk to the German reseller at a trade fair, he said these were "lamp supplies", used for high pressure xenon arc lamps. These
    run off a constant current at some 20...30V, but need up to 70...80V for a short period after triggering for a quick and reliable start. Triggering them requires some 10kV, obviously this trigger circuit isn't integrated.

    Interestingly, this thing also works off 230V single phase, but then this behaviour kicks in at lower levels of current and voltage.
    I've got some manuals with schematics, in case you're interested:  http://wunderkis.de/delta-elektronika/doc/ (http://wunderkis.de/delta-elektronika/doc/) and some teardown photos:  http://wunderkis.de/delta-elektronika/gallery/ (http://wunderkis.de/delta-elektronika/gallery/)

    I'd be interested in your reverse mod instructions, just for curiosity. PM'ed you for that.

    Technically a freebie but I'm still pretty stoked!

    Found this Systron Donner 3101 Gaussmeter in the dumpster behind my university. Sought out the guy I (correctly) assumed had tossed it and got the Hall effect probe for it!

    Look at that hideous 1970's mustard thing! How can you NOT love it?

    Unfortunately the probe has a different connector than the unit, and the unit is heavily modified (more veroboard in it than pcb!) so getting it running, well... we'll see.

    Worst case: groovy enclosure for something else!

    Agilent U1253B from giosif. A single alkaline battery lasted 15.8 hours so not nearly as bad as the 8 they said even if that was probably for the rechargeables. On high brightness, DCV, with about 6 hours using the bluetooth IR accessory. The rechargeable that was in it lasted significantly less time but my new 9V(8.4V) lithium rechargeable haven't arrived yet(the ones I have are all in my smoke alarms). Also for the last 20 minutes or so of battery life the readings were not very stable.

    Well it depends on the detector probe you put on it, but I'd say definitely, yes.

    This guy is using it with a scintillation probe, and he gets a reading well above background:

    Ive wanted to get a geiger counter or similar for a long time. That one looks pretty old. Youre saying you can upgrade it with other kinds of tubes, to make it more useful?  I'd like one that was able to check out food. My friend got one after the Fukushima disaster and she said that some of the food appeared to be mildly radioactive. (also puddles after rainstorms) This was in California in I think it was 2011.  I dont know if it is still a problem. She has a pretty good one. It cost several hundred dollars. It can also pick up beta and even alpha radiation.

    I live in a havily populated area that has several aging nuclear power plants. The idea of a nuclear accident at any of them is terrifying. I dont trust TPTB to tell people if something like that happened. What would be a good all around device for detecting nuclear radiation thats not too expensive. I'd be willing to build it myself - would a meter like this be a good starting point? (more flexible than the ones that come as kits?)

    Keep in mind I've only had the thing for like 5 days, but this meter is litterally just an adjustable high voltage psu, an AC coupled amp and a frequency counter; it is as good as the probe you put on it (wierd connector needs to be swapped, quick mod). It's not as old as it looks, PCB is date coded '92! I suspect it's one of those 'if it works don't mess with it' things where they've been built like that from 1975 and 20 years onwards!

    I like it because I now have one meter that is compatible with all the probes I own.

    That said, in your case I might like a meter that shows dose - µSv/h, µGy/h or mR/h. The little DIY kits are nice enough, and cheapo ebay geiger counters will be very similar in construction,
    but no matter what counter you get, if it just has one of those ex-soviet STS-5 or SBM-20 tubes, it's gonna be a pretty insensitive instrument.


    Oh and WIM is right, gamma spec is really awesome, I found a guy (a bit crudely) modding the RM/5 for this job (using theremino software)! I'd so try this if I didn't have a gamma spectrometer already!

    Interesting data. Does the U1253B have selection for primary or secondary batteries? Its newer OLED cousin (U1273A) has this on the setup menu, which helps with "sudden death".

    It's just like the 1252B where you can select 7.2V or 8.4V but not primary/secondary. It was kind of odd but when selecting 8.4V(which the battery reads when full) the battery indicator never reads full, with 7.2V it went low but unlike alkalines it didn't flash the x on the battery(or it did and I didn't see it which the alkaline did for an hour or so.) So for some reason the battery doesn't really work well with the indicator but 7.2V is what I'd recommend.

    Yea, same as the U128x I think, which use AA. I almost lost mine due to leaking alkalines so switched to lithium primary there. Luckily the battery life on it is very good so not much point in switching to rechargeable.

    Got a Victron IP67 17A lead acid battery charger. Against my better judgement I got the 17A model instead of just going for the smaller/cheaper 7A version, it was only 30 dollars more oh well, at least it will last a little longer...in theory. 5 Year warranty is quite promising too.  :P

    First impressions are quite good, feels solid and the bluetooth app has a lot of settings. (absorption/float voltage adjust was the main thing I wanted so I can properly charge my various car batteries)
    They mis-crimped one of the ring terminals (split/rolled seam and cheap crappy PVC insulated terminal), no biggie I was gonna extend the leads into banana jacks so I can use them with alligator clamps anyway.

    Surprisingly affordable here compared to a "dumb" Ctek charger which I was using before. Voltage reading is only off by 0.02V during storage mode (about 0.1A draw through the leads) so I think the calibration of the onboard voltmeter is spot on. It's a shame it only reads current in 0.1A steps though (voltage in 0.01 steps, including adjustments not just read back).

    Efficiency is fairly good, I'm reading about the 87% mark in the ~50W range, I can't test it's claimed 95% maximum because I can't load the thing high enough. It was 3-4% better than the Ctek from memory at a similar load.

    Down low when it was supplying ~1.3W or so, it was only drawing 2.7W so I'm very pleased with the performance for long term overnight use. I can't remember the exact values of my Ctek MXS5.0 but it was quite a bit worse.

    Ahh it's nice having voltage/current read out over bluetooth, I don't need to whip out the multimeter+clamp meter and open the bonnet every time I want to check up on things now. I wish I could do a teardown but it's IP67 and potted inside.  :'(

    I used to use my Advantest TR6143 SMU to float charge batteries only during the day when the sun was out because I have rooftop solar here. It drew ~200W while only supplying 25W or so ahahahah, but at least I had 4.5 digit precision.  :-DD

    While it's not (strictly speaking) a piece of T&M equipment, I did just buy this.
    Picture of a nice car
    I am not ashamed to admit that I've already done a bit of teardown on it. And yes, I'm enjoying learning its user interface!

    Ah, the Evora GT  :P 

    Nice to see British cars in the USA. I know German/Swedish cars are popular in the USA, how about the other European car brands?
    As long as I can recall I have a weak for British cars. Have owned a Rover many years ago and since 2000 an MGB GT.

    Don't tear it apart, turn it on...... Opposite of what Dave always says.  ;)

    Enjoy this beauty, many safe and happy miles.

    Ah, the Evora GT  :P  Nice to see British cars in the USA.
    Thanks for the kind comments!

    As I've recently learned, there's a small but enthusiastic community of Lotus owners here in the USA. They stopped importing the Elise and Exige a while back because Lotus wasn't willing to compromise those two cars to meet USA crash requirements. The Evora is a completely different vehicle with different design goals so they have been able to meet the requirements (although the front end is different here vs. everywhere else in order to meet the 5 MPH bumper requirement... there's a lively debate about which front end looks better, and some here have swapped for the non-USA version).

    You do see Land Rovers around, and of course the high end luxury brands like Rolls Royce, Bentley, etc. McLaren is here too, often at the same dealers as Lotus (that's the case for my nearest dealer, in Seattle).

    Don't worry, I'm not doing a complete tear-down on the Evora GT. But there are a couple of things I'm considering and I want to do them tastefully, which requires a bit of exploration. For example, while Lotus is recognized as the leader in "the driving experience" and full driver engagement, they are definitely substandard in the electronics department. The passive current consumption of the electronics is enough to drain the standard Group 24 lead-acid battery in 2-3 weeks to the point that the engine won't crank anymore! They actually ship the Evora with a Lotus-branded Battery Tender and the little pigtail comes pre-installed by the factory on the battery terminals (in the trunk under the mid-engine hatch). They openly recommend that you plug in the Battery Tender if the car won't be driven for more than 1-2 weeks. This means folks often leave the engine hatch unlatched to allow the Battery Tender cable to snake into it, and there's been more than one case of someone driving away with the cable still connected.

    So a popular mod is to install one of those magnetic 12VDC connectors on the outside of the car, such that you can leave the engine hatch closed and if you forget about it the cable will just cleanly pull away. Thing is, that connector requires a 1+ inch hole to be drilled somewhere. Folks have gotten creative about hiding it in the rear wheel wells, etc. but I just shudder at drilling a hole like that in a brand new car like this.

    Fortunately, the Evora GT has this one-piece replaceable set of little "bumperettes" on either side of the rear license plate that are just an injection molded plastic part. Lots of people remove that in the spirit of appearance. But those bumperettes are hollow, and I'm thinking of putting the connector hole in the side of one bumperette, which would yield the functionality without touching the main part of the car. Then the question becomes how to cleanly get the wiring from the inside of the trunk to the connector. This is where the partial tear-down comes in... I removed the rearmost panel on the inside of the trunk so I could explore what access is possible. I believe I can use one of the top holes for the license plate mounting to fish out the wire to the bumperette, and rely on the two bottom holes to secure the plate itself.

    https://sensepeek.com/sp100-100-mhz-handsfree-oscilloscope-probe-1Finally bought a pair of Sensepeek SP100 hands-free scope probes (https://sensepeek.com/sp100-100-mhz-handsfree-oscilloscope-probe-1) (aka PCBite probes). They are not exactly cheap, but are of the "when you need them they really are handy" kind. Its very helpful to be able to probe SOIC pins without fear of shorting them, especially when you need your two hands to change the inputs to your circuit.

    To compensate them is a little bit fiddly, though:

    A Siglent SDG 2042X function generator. :scared:

    Why at all? Because I now need a function generator up to 5 MHz or so.
    To date a frequency response corrected sound card to just under 90 kHz
    (see below) would do mostly.  But now the need to make measurements
    up to around 1 MHz became necessary for:
    - Verification of 20 kHz and higher low pass filters cutting out the mush above the audio band.
    - Verification of two home made isolating high voltage probes for
      oscilloscopes based on the design published in Everyday Practical Electronics, Jan 2016.
    - Repairing a R&S UPGR 1 MHz millivoltmeter

    Why Siglent SDG 2042X?
    Was for a while looking at an UNI-T UTG 932. Not available in Germany. Only through Aliexpress  :palm:, which I dislike for payment and warranty reasons. Moreover, the a bit more expensive Siglent SDG 2042X is well supported by https://www.eevblog.com/forum/testgear/program-that-can-log-from-many-multimeters/ (https://www.eevblog.com/forum/testgear/program-that-can-log-from-many-multimeters/) whereas with the UTG 932 I would have to provide the required driver myself and this without a command reference for this thing :-- For me much too troublesome.

    And no. My SDG 2042X will not be pimped to 100 MHz. Simply because I don't need to do so.

    Two gigabit PoE splitters.

    While I have a gigabit PoE switch in my wiring closet for my wireless access points, there are two other units, a PON ONU and my PC-based router, both of which takes 12V power from a barrel jack. Before that splitter each of the two had separate power bricks. Now I converted those into getting power from those in-line PoE splitters so the only thing that remained on the wall is the PoE switch.

    You don't have to if you just want to use it for rough cleaning (the one in our lab only gets tap water plus the occasional shot of citric acid and it's still in good shape after years of daily use), but if you don't want to rinse your boards after cleaning them i'd recommend using DI water (also, it's a good idea to change the water after every 1-2 uses, DI water from an ion exchanger is cheap).

    Never use a flammable liquid (iPA, acetone, etc) as the fluid will get hot (~40-50°C after half an hour without external heating), this can be a serious fire hazard.

    Never use a flammable liquid (iPA, acetone, etc) as the fluid will get hot (~40-50°C after half an hour without external heating), this can be a serious fire hazard.

    There is a good stuff called trans-dichloroethelene (DCE), which is a non-flammable (when mixed with fluorinated solvents to form azeotropes), and not very toxic (benign enough to be approved for use as flux remover in most jurisdictions) flux remover.

    Mix the azeotrope with some alcohol, and ethyl acetate and limonene (both are not flammable in low concentration dissolved in DCE), you get a perfect flux remover.

    There are quite a few such mentioned products available on the market. I use Mechanic N880, which seems to be fairly available in China, then I mix a tiny bit of limonene to it to enhance its capability to remove adhesives and use the mixture as a "one fits all" remover product. Basically it's my version of "cum gutter".

    I am always rather sceptical when someone tries to sell me Fluorocarbons as harmless chemicals... Sure, the DCE part is rather tame and probably somewhat biodegradable, but the perfluoros needed to form non-flammable azeotropes (either some sort of perfluorobutylether or poly-fluoroalkenes) have an extremely poor biodegradability and basically no one can tell you if it has long-term effects on (water)-organisms or humans... (And we are already at a point were you can detect some perfluoro-crap in the bloodstream of basically every person on the planet)
    A lot of this stuff will end up accumulating in the ground water or soil because there just isn't a good way to get rid of it (except from maybe cracking it at extremely high temperaturs in a hydrogen/oxygen stream and hoping that it will end up as HF).

    So yeah, it might be a hella good flux remover but if water (and some added solvents like ipa/acetone/etc in a non-flammable concentration) and a bit of waiting also does the job i don't see a reason to use DCE/fluorocarbon azeotropes.

    (TCE and PCE were also marketed as being perfect, non-toxic, non-flammable degreasers and were used for decades... Until someone showed that they are carcinogens and teratogens.)

    You were right, Distilled water is under $5 for 7 litres in coles.

    Btw, the Ultrasonic cleaner works great with the Chip Quik solder (https://www.digikey.com.au/products/en?keywords=SMDSW.031%201LB) I use and I don't need any chemicals at all - Distilled water does the job perfectly. 6 minutes at 30c and the boards come out since and clean. I give them a shake and then sit them on the bench next to a little fan heater for 5 mins and they are done.  :-+

    Since you've mentioned before you live in southern Shenzhen, where did you get those stationary? I tried a few shopping malls along side metro line 4 (a few around north station and central book store near children's palace) and 2 (coco shopping complex and a few near OCT), never found a good store carrying what I want (Mitsubishi Style Fit and refills).

    Care to share where did you find all of them if not online?

    Ok I will make the explain were I got most of it:

    rOtring 600 MP and BP - Amazon.jp, shipped to HK;
    Pentel Graphgear 1000 MP and BP - got in Japan a lot of years ago;
    Ohto Multi MF-20K3B Multi Pen + Mechanical Pencil, Kokuyo stuff, rOtring Triangular ruler and Pilot Neox leads - JD APP;
    Uni NanoDia and Pentel Ain Stein leads, Staedtler Eraser - Shop in Grand Theatre, under Book City. Simply exit on Line 2 - Grand Theatre, Exit F. When outside, it's the building on the right. The entrance is at the street level, close to a restaurant. From the inside of the stationary shop you can climb the stairs on the left and right corners and be on the Book City store, or the opposite way if you enter via Book City. Can't remember the name of the stationery shop.

    They carry Pentel, Mitsubishi, Staedtler, rOtring, Zebra, Kokuyo, Parker, Pilot, MG, etc... I'm sure I saw what you look for there, is close to the entrance of the shop, centre-right product display, it's mostly Mitsubishi/Uni stuff.

    An Asus Zephyrus G14, indulging my self with octa-cores laptop.  :P

    I was looking at this model, but God damn it, Asus China doesn't offer the 1080p version, and as someone who have used an X1 with 2560*1440 resolution, I know how much I hate this resolution.

    Gnome has bad fractional HiDPI support, so either I run it in 720p equivalent mode (720p images and 1440p text, which some of my applications won't physically fit in), or I run it in native 1440p which puts a lot of strain on my eyes.

    And KDE is not an option. Therefore for me, it is 1080p or 4k, period.

    I was mouthwatering Huawei's new MateBook X for a while (3k*2k, even at 200% scaling I still get 1.5k*1k), but on its final release it has only 14nm CPU, not the rumored 10nm IceLake or even TigerLake, nor 7nm Ryzen 4000U. That, compounded by its passive cooling design, I can already see performance disaster.

    This is unfortunate, but consider Huawei now practically only sells in China, and we Chinese generally are not the fastest to accept new things, like AMD's rising, Huawei will have to not to let AMD to taint its flagship's name, despite it also has some quite decent lower end Ryzen 7-based laptops, just with horrible color accuracy and building quality. I hope with time goes by more "business-oriented" Chinese people will recognize AMD and more vendors will release flagship AMD products.

    So, I will just wait for the new Acer Swift 5 with Gorilla glass and TigerLake with MX350, to be released later this year.

    And no, I will never buy a ThinkPad again. This X1 I'm typing on had crashed 5 times this week (weeks start in China on Monday), and it never crashed on any memtest or CPU/GPU stress programs. Weird, indeed, but it just keeps crashing when I use it normally. My coworker's cheapo Xiaomi runs well, with the same Ubuntu 20.04 and KiCAD 5.

    Yeah, this Ryzen 2 4000 series mobile cpu basically a breakthru in laptop computing, Intel basically hopeless against it, not too mention this tiny 14" beast have a really good battery life too, and this particular G14 also can utilizes USB C PD charging, slower though compared to using it's brick charger, but in mobile computing, its really unbeatable when in comes the convenience.  :-+

    See how AMD kills Intel.  >:D

    The problem is not the availability but the price of those connectors… 240 bucks for six connectors is just a little bit too much for my taste (especially given the fact that they are rated for 500V RMS but my 237 can output 1.1 kV).

    Yes! Ferrule crimpers are great. So many uses. Being able to undo & reconnect wires in screw terminal blocks any number of times, without rapidly cutting through all the wire strands.
    I even use them on most mains wiring now. Btw, you can produce a rounded result on large ferrules (to make them fit in tight round terminal sockets) by crimping once, rotating 45 degrees, then crimping again. Just have to get the angle right - balanced 'right on the tips'. Otherwise it pops back to match the square jaws.

    Now go to Aliexpress, and buy some bulk assortments of the ferrules. They are extremely cheap that way, compared to buying from local stores.

    I got a very similar hex crimp Molex ferrule tool not too long ago.  Definitely very useful and handy to have, and with the radially closing die jaws, it's much easier to get the wire out than it is in the more common plier-style ones that mash them into a three sided die.

    No, she's reading from a text file in our shared volume in our AFS cell (http://www.openafs.org/), and, in this case, telling her sister and brothers what I'd wished for.

    The sleeve crimper fully open is 7.5mm flat-to-flat, and just under 8.5mm point-to-point.   I found them on the Firth of Malevolence for a bit over 120 US clams shipped, so I figured I'd grab them after looking up the price at DK/Mouser as I'd been toying with the idea of getting a ferrule crimper for a while but wasn't crazy about the plier-types.  Proper crimpers are insanely expensive, but they're just so nice to use.  I'm not sure how they'd do on regular crimp lugs as they're designed for the thin copper wire sleeves and as they're 'self adjusting' my assumption is that the jaws are pushed in by spring pressure rather than a solid mechanical actuator.

    As to what you have coming - a new soldering station?   :-+ :-+   :P   I don't even want to *think* about what it would cost to ship a 4145A and/or B down under - they're rather bulky beasts!  (And have triaxial connnectors, too.   I missed buying a test fixture for them that included cables a few years ago and am still kicking myself for not bidding higher.   |O :palm:

    Thanks for the measurements. I'll see what I can find on the eeeeeee-cove.
    The 4145B. Fingers crossed against the shipping demons. The manuals - I'd bought all 3 prior to buying a unit, mainly for interest. But it turned out very well. The A version manual includes board schematics, while the B manual doesn't, but does have more on the display unit. Then the manual just for the display is significantly different again.

    Triaxials - covered. I found lots of the cable 2nd hand very cheap, and also an affordable source of the connectors on Aliexpress. The quality turns out to be just as good as the 'real' ones.

    Now I get to embark on the HP 16058A side quest. Are these things the most expensive box of air ever? Whhhhy are they so expensive? And how does _everyone_ that ever bought a new 4145B manage to lose all the invariably supplied standard accessories?

    I'm really looking forward to messing around with the vector display. It's a very cool thing all on its own.

    TUC-100 (http://"https://eleshop.eu/tuc-100-ultrasonic-cleaner.html") ultrasonic cleaner with 10L of Safewash SWAS (http://"https://www.solderconnection.com/specsheets/044SWAS_1.pdf") cleaning fluid. This is to replace the completely unsuitable little ultrasonic cleaner that I picked up from Amazon that is designed for cleaning jewelry.

    I'm hoping this will solve my problem of always having trace amounts of omnipresent "ambient flux" making things stick to my tweezers and so on. Also to reduce wear and tear of brushing fairly hard and laboriously with IPA+toothbrush to get tacky flux out from between pins.

    The cleaning fluid datasheet boasts that it should be able to absorb about a kilo of horrid burnt flux residue and still produce cleanliness up to military standards (if I'm reading it correctly.) That should keep me out of trouble for a decade or two! (He says not having reviewed what military standards are but assuming they are above the ad-hoc cleaning of my workbench!)

    An F.W. Bell gaussmeter in a bit rough condition- Electronics looks as new though, and look at the previous owner's cal stickers!!! That alone is enough to love this 1970s bit of gear :)

    Well, it is all coming together, VERY slowly.  I bought a Quad QSA-30A pick and place machine, made by Samsung.
    It is about a 2000 vintage, I had some misgivings on getting such an old machine.  But, my Philips CSM84 that I started with is now 25 years old and solid as a rock.  I have only had one electronic problem the entire time I've had it (13 years) which was a conveyor sensor that went flaky and then died.

    So, I thought I should have similar luck with the Quad.  The machine has been hacked over by monkeys, and I'm giving our simian cousins a bad rap there.  The feeder power supplies have been blown out and replaced twice, leaving the old supplies in place and wired around, now using a combination of used PC power supplies.  One of the placement heads was replaced with one from a similar machine, but the rotation motor was not compatible.  In working on that, somebody took the ball spline out and lost about 30 balls!  I had to mike the balls and order some more and try to reload the spline -- VERY tricky and tedious.  I ordered a motor from China and put it in, and now that works.  Now, the fiducial camera had partially failed, it will not sync to the external sync supplied by the vision system.  it worked 3 weeks ago.  The main interface board between the VME computer and PC went bad a week after I got it, and I spent a week trying to diagnose, and then finally ordered a replacement from Korea.  That never came, so I had to order another.  That came quickly and the machine comes "ready" again, so I can continue fixing stuff.

    Oh, yeah, I got the machine for $500 plus buyer's premium, I was the only bidder.  After very careful inspection of the auction pictures, I bought what appeared to be the newest and most complete machine they had.  I can't imagine what shape the others were in!

    Deionized water.

    I tested my TUC-100 ultrasonic cleaner with SafeWash fluid for the first time and it worked well: removed all the Amtech tacky flux from my boards and got my tweezers so clean that parts don't stick to them anymore. However, the metal surfaces like solder joints all came out looking cloudy with some white residue evenly distributed across them. Hypothesis is that this is salts and minerals deposited during my post-wash rinse with tap water.

    Something I DIDN'T buy today was a new thermal imager/camera/sensor. I have one from Seek Thermal that plugs into a cellphone/tablet USB2 connector but those are few and far between on today's cellphones, and Seek's app has stopped being compatible with my tablet.  :wtf:

    I need to do a thermal study on a power circuit I'm working on and was going to post here for recommendations on an inexpensive camera, when I remembered that my wife had saved one of older Motorola cellphones. First thing this morning I grabbed it, downloaded the app, plugged in the sensor, and voila - I'm back in business.

    Here's an annotated image looking at the breadboarded circuit with the 13A load running at 50% duty cycle (2 seconds on/off). A nice $0 solution thanks to my wonderful wife!  :-+   :clap:

    That's why I avoided the phone linked thermal cameras, in case it was a brick after I upgraded my phone. I waited until there was an affordable stand-alone unit that fulfilled my needs. In my case it was a HTI HT-18 that I chose and I haven't looked back since. Really happy with the device still and still fulfills all my needs.

    Yep, I can't argue, and my replacement plan was going to be a standalone unit for exactly those reasons. But I got this Seek Thermal unit on a whim, basically an impulse buy several years ago for under $200, and no standalone unit could match its resolution at anywhere near that price.

    My plan now is to keep the old phone with the sensor as a system. The phone doesn't have a SIM card so the networks don't "know" about it. I'm keeping it in Airplane Mode so all of the wireless interfaces are disabled so, amongst other things, Google doesn't try to force an Android update on it. I pull the images using USB. It should be an isolated island and continue to operate for quite some time, so I'm back to having a reasonable thermal imaging system for the low incremental price of $0.  :-+

    For the E-Bike, get rid of bullet connectors and replace them with XT60 connectors, you can also get a three way XT60 connector for the motor drive.
    The bullet connectors are crap as is the wiring sheath, when they get hot due to contact resistance they wreck themselves and the insulation on the wiring.

    I bought a Hewlett Packard HP9100A
    I actually bought it... I bought my holy grail!  ;D

    Sure, it's broken, but I could actually afford this unit, and that's what matters here. I routinely see these sell between $3000-$5000 when in working condition. When broken, I've seen these sell anywhere between $800-$2000. I actually got this for the lowest price I've seen in the past 11 years, and belive me... I've been watching every sale between then and now that I've spotted online! I can always gradually work my way through all the resistors and diodes, testing for failed components. Maybe I'll even get it running someday.

    This is purely an acquisition of desire, not need. I've wanted one of these for a quarter of my life, and now I have this piece of engineering beauty! Sure, I could have bought a new CPU and motherboard for what I spent, but I think I'll be happy to have this beauty from 1968. Pics are the seller's pics... I've bought and paid for it, now to hope the UPS guy doesn't abuse it!

This replaces my Tek 2235 which still worked great but had too many limitations (no single shot acquisition and size being the big ones).

    Just got that AMIQ. Now to get it working!

    On power up it emitted a series of beeps that was very familiar. On opening it up I realised it is the BIOS beeps for a malfunctioning graphics card.
    Of course it does not normally use one. I plugged an old ATI card and could see the boot up procedure with Caldera OpenDOS 7.01 and a notice about "not for commercial use" or such.... :-//

    Next thing to do is image the hard drive and locate user and service information to use the GPIB and talk to the unit. If I get it working I'll start hunting for a SMIQ 03 to pair with it for I/Q modulation.

    Somewhat, yes.

    The mains switch is a goner, needs a new one. (funny enough, the schematic I've got does not show it being a 2-pole switch, so I'm having to trace out and replace accordingly)

    The Volts pot seems OK. Not been able to test yet.

    The Range / Metering switch is compromised. It's been kicked in, and the switch wafer assembly has separated from the bushing that holds it in the chassis. Needs out-of-chassis repair. Supposedly unobtainium since it's concentric and all. I have hope it will be repairable.

    The meter came back in place with some persuasion, and the movement is OK. It gives a reading if I probe it with a multimeter in Ohms mode, and the multimeter reads the coil as some 100Ω.

    Hakko FM-204 desolder gun for the bench. Not desperately needed, as I don't deal with that many TH parts, but when I do they're often connected to power planes, and really need some work to remove...

    1. Very primitive LCD display. 320*240 for a very large size means pixel size it ridiculously large. Also scanning is visible and refreshing is very slow (somewhat 10fps). Viewing angle is great, but color is not so good.
    Nice summary; Flukes tend to have those "ancient displays" - I still don't know if it is due to them sticking to an older microcontroller or perhaps they feel that less resolution is more robust for the field (in contrast with TFT stuff).

    2. PC program doesn't work well under Windows 10 due to the USB driver is proprietary and supplied driver can't work under Windows 10. Very picky USB stick compatibility, so be sure to get a small and old drive.
    Did you check if your pendrives are formatted in exFAT or NTFS? I noticed that most embedded equipment usually works (or performs better) with FAT16/32.

    4. Huge power brick. 10W of power in the size of a 330W gaming laptop power brick size, presumably due to CAT IV requirements.
    I also have some equipment that has large bricks; I love them and the fact they use larger capacitors with longer life (the ultra-compact capacitors usually are rated for less hours). Not to mention transformers and room for extra insulation around the board.

    The scope does, however, work with the same drive if I format only the first 2GB of space and leave the rest unformatted. It seems the firmware doesn't like larger drive partitions.
    This is annoying indeed. Perhaps they used int32_t as the disk size; who knows?

    I have some 512MB pendrives just for this task - given the low resolutions of the screens, such small size holds an eternity of screenshots. Sure the full 140M points of my DS4014 quickly exhaust it, but it is quite rare for me to actually need it.

    Got the Quick TR110 hot air pencil today. Quite nifty. I'm now able to work on individual 0402s using hot air pretty comfortably. Happy to have that capability for 300 euro.

    There's a curious feature where you set a "working time" (default 30s) after which the station kicks into rapid cooling mode at maximum air flow, as if the handpiece had been holstered. What's all that about? Caught me by surprised on my first test here and blew a resistor off the bench:

    Otherwise impressed with the unit and how it handles although the UI is one of those digital disasters with too many modes and options, not the same nice feeling as their 861DW.

    After seeing Dave review it recently, I bought a KOTO Fume extractor to replace my cheap and nasty ebay unit. Unfortunately, shipping is expensive so landed it cost me $192 Ass-trailian Micro-Pesos. Still seems like good value compared to other alternatives.

    For me it's still $50 AUD cheaper than a Hakko FA-400 which is nothing to write home about. It's also $1,400 cheaper than a Hakko FA-430!

    Another used Japanese PCN's power resistors hoard.  :palm:

    Smaller ones are rated 150W(mounted)/105W(free air), and larger one is 300W/210W respectively.

    Accuracy 2%, 260ppm/C temp.co, can withstand 5X overload for 5 second, with accuracy within 2%, and with dielectric strength 1500V AC for 1 min.

    Datasheet -> PCN IRH Series power resistor
     (http://www.pcn.co.jp/PCN_PDF_E/e-irh.pdf)
    The "W" attribute at label means low inductance series, measured with LCR, all have approx.  1uH@100kHz, not sure if these considered low inductance.  :-//

    As usual, shot with TO-220 as reference size.  :P

    My old HP 1630G is far from the best LA I have, but it's still my trusty, simple favorite.  Recently an identical one was listed on the 'bay, as an auction starting at one cent. Hmm... I wonder? I set up a low snipe bid, just in case everyone else thought it was too ancient to be of any interest.

    And so, behold. A really nice old logic analyzer won for ONE CENT. (254706863961) The seller was good about it, glad it was going to a good home. He did a very solid job of packing, . The international shipping baboons (UPS this time) did their worst to the box, but thanks to excellent padding the 1630G came through perfectly.

    All it needed was one dreaded RIFA mains filter cap replacing, before power up. It works!


    Wish I'd had the same luck with two other recent buys:
    * A HP 16500C LA. Sold cheap as 'for parts'. Arrived undamaged but it turns out the PS is sick, plus HDD and MB memory DIMMs had been removed. Hopefully I can fix the PS, then scrounge a suitable HDD, reload it, and find correct DIMMs.
    * A HP 4145B, working, perfect condition, relatively cheap. But despite adequate packing, UPS managed to give it some dinged corners on the way from USA to Oz. Heavily dropped, apparently. At least it still runs, but the dings are very disappointing. Shipping insurance claim time.

    To prevent you from cooking the chip or PCB. You should adjust parameters and/or use a hot plate if you can't blow a part down for 30 seconds.

    I will try to get used to that. I have to say I'm surprised that it instantly switches from low-flow heating to high-flow cooling. Isn't the expected behaviour that the solder will be molten and the part immediately blown away? Maybe I need to listen for the beeps and point the iron somewhere else during the transition.

    A Prusa i3 MK3S (as a kit - will keep me busy the next evenings I guess). Finally wanted to have a 3D printer that is just a tool and not a hobby (although I liked tinkering with and improving my K8200 it just needs too much attention)
    And a TFMini Plus range sensor - I need a car position sensor for my garage (used MaxBotix ultrasonic sensors before, but they are problematic with temperatures around 0°C). I will see how this sensor can deal with the shape of the car.

    These kind of linear supplies used to be very common. Many companies made them. You will probably find an LM723 or equivalent on the board. The main chip could be marked with a special number. They all had a similar form factor.

    They should be reasonably good.

    Two rectifiers suggest it is an old style "fullwave rectifier".

    These use a centre tapped secondary on the  transformer with each half winding producing the full ac voltage needed to produce the DC output you want.
    On each alternate half cycle one diode of the pair conducts, so it is still full wave rectification.

    These were common in tube rectifier times, as it was cheaper to wind the transformer with a centre tap than to use four rectifiers.
    With solid state rectifiers  it is usually cheaper to use four rectifiers with an untapped secondary winding.

    In some special cases, like if a manufacturer makes, say both 12v & 24v supplies, the same transformer could be used in both cases, with a "full wave rectifier" for 12v , & a "bridge" rectifier for 24v.
    The saving in inventory costs may justify the cost of the tapped secondary.

    That seems very likely as there's 3 secondary taps.

    Just ordered a DSLogic Pro 16-ch version. Need to work on some JTAG devices and don't have the time to write decoder plugin for my AD2. Delivery is due in 150 minutes.
    The software is intuitive, and works just right out of the box.
    DSView (https://github.com/DreamSourceLab/DSView) is Sigrok-derivative, and both are licensed under GPL.

    FWIW, the under $10 MCU123 and Saleae Logic clones on fleabay work fine with Sigrok, and use Sigrok's own fx2lafw (https://sigrok.org/wiki/Fx2lafw) firmware – so the only thing "Saleae" on it is the sticker on top; the design itself is almost straight off Cypress FX2 application notes, and you won't be infringing on anyones intellectual property if you rip the sticker off.  These are based on Cypress FX2, and limited to 24 MHz sample rate and 8 channels, but for hobbyists working on Arduino-like stuff (serial, SPI, I2C, WS2811/WS2812B/APA102 etc.), can be very useful.

    I also have Bought a DSLogic Pro a few months ago, and it's a great tool.
    Be aware that those relatively low-cost analyzers are fine for "low-frequency" logic, but useless for anything above ~50 MHz (clock rate). So don't expect to be able to use them to capture like 100 MHz+ digital signals for your FPGA design, for instance.

    I ACTUALLY used food delivery service (meituan.com) to deliver this thing. They also offer goods running service at a cost higher than their food running service, but they do offer that.

    DreamSource Technology is only 26 km from my company, so it's a relatively short trip and it only took 1.5 hours because the driver had to pick up and deliver more goods on the trip here.

    In most Asia developing countries, motor cycle ride for hire are plenty and norm, like food delivery and merchandise delivery too.

    Motor cycle is much faster than delivery car/truck in big cities, and online shopping in the same city when opted for shipping with instant delivery, usually they arrived within hours and norm, and with tracking too of the rider's GPS position once they picked up the merchandise.

    Title: Noga Deburring Tool
    Post by: BravoV on October 25, 2020, 09:58:05 am
    Doing a lots of metal works recently like cutting and drilling, as I'm an amateur and also clumsy  :palm: , the sharp edges from the metal cut and drilled holes cut my hand and fingers a lot at many occasions and bleed like hell, so tired of using file or sand paper, and so pissed  >:( , and told my self enough is enough.

    Bought my self the duck's gut of the de-burring tool and the extra 10 carbide blades, Noga, made in Israel.

    $20 for this Motech MT 4080A  :)
    Wow - awesome catch!

    The Motech MT-4080A/D is re-badged and sold by B&K Precision as the 886 and 885 LCR meters.  (For a lot more than $20!)  There's schematics, calibration, and other service information posted in this thread for the 885/886:

    FYI.

    MarkL, thank you so much for information and the forum link as well!

    Did not know that they where re-badged and sold by B&K Precision as the 886 and 885 LCR meters. I got this from a friend of mine and he did not really know what they used it for. The company he worked for vent bankrupt and no one had a clue what it was!  ;D All was there in a box: Kelvin clips, SMD test probe and calibration plug. I saw a price that was nearly $1000, but that was a while ago. Very kind of you to share that information which sooner or later will come in handy.  :-+

    I was more thinking to use them to hold things that may get hot when soldering, particularly when using hot air. Sometime it is small PCBs that get hand assembled or reworked.

    An Avometer Model 7, Mark 1 (I guess; it lacks the Mark 2 features), made November 1950. It is in almost perfect condition, bar some rust in the battery bay, and binding posts miss some parts. I need to verify function on all ranges. The movement is free and responds to stimulus.

    Most important: It won't get turned into a lamp holder.  Pic from ad:

    Ah ha! I thought that looked familiar. Checked in my 'old manuals' stack, and I have an original TF 2700 Universal Bridge manual. Operating, theory and schematic.

    The manual and the instrument should come together. It's yours for postage (from Sydney Australia.) Or I could scan it.
    Another alternative, just mentioning it for completeness: If you aren't likely to use that, I'd buy it from you (though only if cheap.)
    I collect old test equipment. (Same as about 80% of eevblog members.)

    Hi TerraHertz and thank you so much for your offer!  :)

    I will take a serous talk with myself if I want to keep it or not. It is late night here in Northern Sweden - 02.15 - so I will have to come back. Of course the price would be cheap because the shipping cost, even though it is rather light weight, be a big part of the total expense. Well  ... I have already talked to myself and if you want it just drop me a pm and let me know what you think it is worth. :)

    Imdes Mini vapor phase reflow oven for €866 promotional price at Eleshop (https://eleshop.eu/vapour-phase-mini-condens-it.html).

    I've been on the fence about this for six months. I want a vapor phase capability for working with really large BGAs, and I had been planning to take the asparagus pot approach, but this feels like a relatively economical upgrade from "prototyping" to "small production" capability. I'm betting that I'd have ended up buying one within the next year and won't see a better price than this. YOLO!

    I got a cheap 30kg spring balance for some ghetto tensile strength testing of crimp terminals. Made in Germany which was a pleasant surprise.

    Well I can confirm the TE PIDG terminals work nicely with both the Pressmaster KSA0760 and the official mil spec TE/AMP 59250 tool. I tried it with 22awg wire and the wire just keeps breaking at the ~11kgf/24lbf mark, which is around the break strength of normal 22awg wire.

    I find it interesting that the Pressmaster consistently broke at the strain relief crimp, but the AMP broke where the conductor crimp is. Perhaps the Pressmaster is overly stressing the strain relief crimp, which makes sense because the AMP has 4 adjustment settings for wire insulation whereas the Pressmaster cannot be adjusted.

    I want to get some high tensile strength wire for testing (specced up to ~16kgf break strength for 22awg)... well maybe not at a dollar+ per foot, ouch. Ughh I'll try fit it in with my next digikey order.  :P

    For some reason I was nervous using the crimp terminals at the thin end of the range (22-16awg normally) and was concerned it would be a bit weak, but it looks like I was worried over nothing. Mil spec was 15lbf for 22awg, UL spec was 8lbf, so it looks like the AMP 59250 still performs extremely well (24lbf, wire strength) despite its age/wear because I did get it used for real cheap after all.

    I briefly tested 16awg wire and I maxed out the scale at 30kgf/66lbf without the wire or crimp failing, it's reaaaaally uncomfortable to pull that much so I called it quits. Mil spec is 50lbf (UL is 30lbf) and break strength is supposed to be around the 75lbf mark for 16awg wire.

    Fishing scales would be my choice for checking breaking strain as many have a sliding marker that remains at the last highest measurement.
    Like these from Shimano:

    Those are often called "fish scales", "kalavaaka", here.

    They say that a few decades ago, in 1980s, in Northern Finland a lady had to give birth in an old fishing cottage frequently visited by then president Kekkonen.  The midwife forgot her scales, but there was one left by Kekkonen, so they used that one.  The birth weight for that baby was recorded at 40 pounds.

    I guess what I'm saying, every now and then, do verify that the spring is still okay, and the scales still "in calibration".

    Those fish scales were likely "adjusted" to help the fisherman with bragging rights.

    If the kid really did weigh 40 pounds, I'd guess that the kid would be able to walk before the mother recovered enough that she could walk.

    Calibration is by definition the comparison between the results of a measurement device and a known quantity (ie: a standard). It doesn't change anything it only establishes the offset.

    Well, duh!  Obviously.

    In practice, if the spring is overextended (say, due to trying to measure something over its capacity), it will deform, displaying larger tension than actual.  For fishermen with a competitive streak, or overeager lackeys trying to lick arses, a little 'stretch' like that is sometimes too tempting.  Regularly testing it, say before and after a series of measurements, against a known tension (weight) lets you know whether this has happened or not.  It's a simple pass-or-fail test.

    The banana plug part, if not removable, makes the probe unuseable for much work.

    I bought a similar set of leads, as they were the only ones available at the time, & found that the thick "banana" part prevented using the probe for such things as checking continuity on flexible cables with connectors/sockets attached, such as microphone cables.

    They were also troublesome when looking at the pins on some edge connectors.
    I eventually became heartily sick of them, & finally found some normal probes at another supplier.

    The Pro'sKit SS-331H is terrific. I've been using it for a year, and boy does it save time compared to even excellent manual desoldering pumps such as the Engineer SS-02. A total godsend if you desolder high effort stuff such as keyboard PCBs.

    A mains cable for my -hp- 400H (Valve AC volt meter made for Europe in then Western Germany, so better connector than that little oval shite they had from the US before everybody went IEC C14).

    Just a bunch of odds and sods that I have been missing for a while: some RG-174, soldering sponges, Y2 caps, switches and a few 0805 R's to help fill out the inventory binder.  I had to place an order for a single $15 chip with DK anyway having smoked the only one I had for my current project.  But SWMBO can't resist getting free shipping so it had to be expanded to $100.   ;D

    An early '70s VTVM, the RetexKit VV-1. In fact a clone of the HeathKit V7-A or EM-11E (E for Export).

    It was sold as a kit in Spain under license from HeathKit. It is in very good external condition albeit with no probes. I had to make one for DC out of a malfunctioning chinese oscilloscope probe. Some resistors have drifted in value and I'm replacing them to get accuracy in all scales. Also had to tame a bit the power supply circuit as it was designed for 125V / 220V. There's nearly 240V at home and plate voltages are out of spec. I'm having a lot of fun restoring this thing...


    [EDIT]: corrected typo.

    A Mikrotik RBM33G (https://mikrotik.com/product/rbm33g) RouterBOARD, and a two 1.54" IPS panel 240x240 display modules (https://www.buydisplay.com/1-54-inch-tft-ips-lcd-display-module-135x240-spi-for-arduino-raspberry-pi) (with a PCB instead of a FFC/FPC cable) from EastRising/BuyDisplay.com.
    The RBM33G will be a 4G/LTE router/firewall running OpenWRT, and one of the display modules a small status display for it, hopefully.  (I'll need to write userspace support from scratch.  Note that although the pins are marked SDA/SCL, it uses the typical 4-wire SPI: clock, data, chip select, and command/data.)

    (http://mikrotik-routerboard.af/wp-content/uploads/2018/11/RBM33G.jpg) (https://www.buydisplay.com/media/catalog/product/cache/53fd08fe2cb06c4269619329bc634cc8/e/r/er-tftm1.54-1_top_view_1.jpg)

    I forgot all my serial adapters have TTL level outputs instead of RS-232, so now I'm waiting for my adapter to arrive how much work it is to add the status display; whether the GPIO pins are sufficiently supported by the Linux kernel, or if I have to use a microcontroller in between.

    The two top left board sockets on the RBM33G are USB-based mini-PCIe slots for WWAN modems; I'll be using a Huawei ME909s-120.  The one top right is a M.2 NVMe 2242 slot for a PCIe-based SSD, next to an USB 3.0 socket.  On the bottom, you can see the RS-232 serial port and three gigabit ethernet connectors.  I've ordered a Kioxia BG4 128GB 2230 SSD (removed unused from a Dell laptop) as they're known to work with this board, and it was cheap enough; I like to play with this kind of hardware, so I think it'll be useful for me.  An SSD is completely unnecessary for normal router/firewall use; it has 16MiB flash for an OS built-in, and a smaller separate flash for a bootloader.  And 256MiB of RAM, so OpenWRT should run just fine on it.

    (Simply put, I got fed up with crappy USB-WWAN adapters, and wanted something really designed for this kind of use.  The USB adapters only have a DC-DC converter from USB 5V to 3.8V, and some passive decoupling capacitors, but even so, the ones I can find are just.. not something I can rely on.  An LDO generates too much heat.  I'm not an EE, and don't trust myself enough to design the board layout using TI TLV62569DBVR buck controller, because of the switchmode EMI, although it'd be near perfect for this use case otherwise.)

    But no, 28 in one order is the biggest thus far however just keeping reasonable stock levels is a right PITA ATM.
    At one time I could get a few in by air to carry us over until a sea shipment arrives (1 week vs 1 month) but even by sea is troublesome these days as the vast majority of world freight now comes by sea until we get this CV thing under control and return to some resemblance of the way things were just a year ago.

    I can beat that: My wife helps me do detailed reviews of PCB artwork. We have an associate who does the layout, then I review the artwork trace by trace while she handles the schematic. She knows almost all schematic symbols now, and requires almost zero hand-holding. She marks what she's covered with a highlighter and has caught many an error. Our PCB guy now asks if SHE has signed off on a given board design, rather than me. I definitely married the right girl!

    Right.....until her fascination in your hobby wears off.  ;)

    Nearly 40 years ago as newlyweds I remember populating a stereo preamp kit so we could play our teenage acquired records on our old valve stereo system that wouldn't support a magnetic pickup. Her, armed with a resistor color chart and a component chart would pass me each component as I called out the R1/C2 whatever and after some time she got pretty fast at recognising values correctly......but now it's 'buy one already made and tested' !   :horse:

    We've been married 40 years so she's had ample time to back away. Fortunately, she recognizes it's part of my profession and our income stream so she's very supportive. She also handles the accounting, taxes, etc. of our company so it's all just part of our environment.

    She's picked up an impressive amount of technology in the past four decades. Early in our marriage when she got her degree, she was required to take a technology class of some sort. This was back in the 80's when PC's were "the new cool thing" at home and in the workplace. The professor started talking to the class about "RIOS". She bit her tongue but finally couldn't take it any more, raised her hand, and asked "What does RIOS stand for?" His answer: "Random Input/Output System". She could not let that go, and corrected him in front of the class. He replied with certainty that he was correct, and she countered with "My husband is an Engineer, and several of our friends are Engineers at HP [one of their T&M divisions used to be located here so he would have known about them], and I'll be happy to have them come to class to discuss it." She told me this the evening of the day it happened, and I told her to prepare for an F in that class!

    Fortunately, the professor was a stand-up guy. He did his own research, owned up to his mistake in class, and they went forward on good terms. She got an A too.

    I hear what you're saying, but at this point I think she's fully integrated (perhaps "resigned" is a better term?) into the architecture of our marriage. I'm not concerned. Yet.

    While on biz travel, out of town, spotted a local black smith at the town I visited, and ended up brought home a short sharp thingy.  :P

    No, its not the elite high quality Japanese sword, but from little chit chat with the creator, he honestly admitted its from car's spring steel, once forged, its properly hardened (like properly quenched and etc) and also it was properly through 1 full day of tempering at exact temperature (if I'm not mistaken  ::) ), and let it cooled slowly for few days, then did the finishing like sharpening and polishing with minimal temperature increase, and finally encased in hard Indian rosewood. I trust him after took a short tour around his workshop, it was fun.  :-+

    Here's a recent arrival of mine, far more mundane. A HP 5004A signature analyzer.
    A lot of HP equipment of the vintage I favor has service manuals oriented to fault finding by 'signature analysis.' I've wanted an original 5004A for a long time, but vintage gaming machine enthusiasts also want them, and bid up the prices on ebay out of my preferred range.

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1120160;image)

    This one is missing the carry handle, which reduces the appeal for collectors. Somewhat... it was still bid up, and US$82 isn't cheap imo. Anyway, it works, though needs a little work to repair a cracked PCB in the probe.
    If anyone happens to have a wrecked one they could spare a carry handle off, please let me know.
    Btw, yes I know the Sony/Tek 308/338 has signature analysis too, and I have those. But wanted a 5004A for historical reasons.

    Incidentally, notice that the display is NOT hexadecimal. It's a funny symbol set unique to HP signature analysis. Here's the complete set, from the 5004A manual. They really wanted the letters "HP" in there. Spot the extra weirdness.

    The hex characters B and D are impossible to uniquely represent with that 7 segment display, so something had to be substituted, or a more expensive display used.   H and P makes sense as substitutes and gives a tiny smidge of marketing.

    Rack M6 cage nuts and screws with those black plastic dress washers.
    I'd found a bag of the washers a while ago, really like them. They look nice and prevent scratches on instruments.
    But I used them all up and was too slack to search for a source to buy more.

    Of course they are easy to find... here's an Aliexpress seller. I've bought 50 sets for US$13.50
    When they arrive I'll find out if the store pics are CGI and if the things are even similar.  I notice the washers are said to be PVC not nylon. Not sure if that matters.

    It's a laser, out in the open, 20W. What do you do for not just your eye protection but anyone that might be passing (or inqusitive cats)?

    The ablated stuff has to go somewhere. What do you do about not getting it up your nose?

    I'm kind of interested in replacing my PCB mill with a laser of some kind. Is this the sort of thing I should be looking at? It would be cool to be able to laser-cut stuff, but frankly my needs in that line haven't woken up yet.

    https://www.youtube.com/watch?v=i1zI0MeUt_o (https://www.youtube.com/watch?v=i1zI0MeUt_o)

    I know I spent the money of a MOPA engraver for a conventional Q-switched laser engraver, but I do love its smaller size and different design (rather than the three "traditional" designs every Chinese fiber engraver uses).

    I feel comfortable for spending a bit more (I've seen sub-$1k machines of the same paper spec) to support innovation, and I believe if a company can design a new machine rather than using other people's design, they must know their business.

    This device will be used in a few applications, including laser PCB etching (direct copper ablation), laser micro via drilling (for multi-layer PCB component embedding) and laser defined selective reduction (reducing CuO-epoxy mixture to Cu and water/VOC vapors), rest of common applications like engraving, marking and IC decapping.
    Nice, you should start a thread about the stuff you do with it.

    It's a laser, out in the open, 20W. What do you do for not just your eye protection but anyone that might be passing (or inqusitive cats)?

    The beam is of fairly high divergence, and a few cm over focal plane it is no where close to be dangerous.

    Also the wavelength is poorly absorbed by human eyes, and the device comes with a pair of 1064nm rated goggles.

    That's a really, really dumb idea to just run it in the open... The backscatter from a 20W YAG definitely has the potential to blind you. Second, the eye still kinda focuses at 1064, even though you can't see it. Third, i wouldn't trust some janky laser goggles from an Alibaba seller, proper NdYAG goggles start at only 70 bucks. Just get proper goggles and shielding for the laser... The cheapest option would be a plastic/wooden box with a webcam inside it, if you want to monitor the progression.

    Right; I do believe it was a deliberate design choice on behalf of HP.  I can see the benefits of both; such small details are sometimes surprisingly effective.  Compare to e.g. rounded display corners on classic Mac OS; it's a very minor detail, but made a big impact on human users' brand awareness.

    The above hexadecimal set on 7-segment displays is probably as old as seven-segment displays themselves, and I am 100% sure HP folks knew about it; just chose to not use it.  I was just surprised you seemed to be unaware of it, that's all.

    All small, bench-top Chinese laser engravers, including those certified and rebranded ones like Trumpf Laser and other well know brands, use this open design.

    Those standalone lasers engravers typically need to be integrated in a machine, or at least the ones I know. I agree the information on the net is not always clear, but I doubt there is a laser engraver from a reputable brand were the manual states it can be used without a safety enclosure.

    when ordering e-bike docking type Lithium Battery packs
    buy all you need at one time.   
    because the battery pack case designs can change without warning.  on-line shop images out-of-date? showing old case design.
    leaving you with two or more incompatible battery packs that will not dock the same e-bike battery cradle.
    even if the size watt/hr and voltage are the same.

    e-bike battery case designs are not the same    |O

    So far, nobody noticed (commented on) the detail that HP's 7-seg symbol set on the HP 5004A has two zeros. Resulting in potential ambiguities.  Probably not too serious for signature analysis, but still...

    Did they do that just to save a few gates in the 4-bit to 7-seg decoder logic?

    Another recent buy: HP 1670D. Cheap because of the broken knob, but it comes with the knob and appears to be a clean break of the shaft, ie can be glued.
    Why? See my sig.

    Incidentally, this may interest those doing HP LIF <--> PC DOS file interchange. The 1670D has HPIB, and quoting the programming manual:
    Quote
    The MMEMory (mass memory) subsystem commands provide access
    to the disk drives. The HP 1670D-series logic analyzers support both
    LIF (Logical Information Format) and DOS (Disk Operating System) formats.
    The HP 1670D-series logic analyzers have two disk drives, a hard disk
    drive and a flexible disk drive.

    Ok, I'll comment.  It's a mis-print in the manual.  That snippet from the manual is showing *17* symbols because they accidentally duplicated the "0".  The output from signature analysis is still 4 x 16 symbols.

I took advantage of their feature of letting you buy extra panels (I need to attempt making a bezel for a 1.8 LCD and have some doubts about getting it done in one try :) ). All good.

    Only US$50

    Need something to do while they count votes.

    To follow up and in case anyone else is interested or thinking about android programming. I did get around to starting to play with this. It is pretty junky in the sense that it seems to be a 100% Google monstrosity (took 10 minutes to figure out where setup was to get to a screen for USB debugging).

    I installed Android Studio and went through the tutorial here: https://developer.android.com/studio/write/layout-editor#intro (https://developer.android.com/studio/write/layout-editor#intro) I kept getting an error in the final app. I rebuilt it from scratch three times (which was actually a good learning experience) but still could not figure it out. I knew that a reference was off but I did not appreciate what an id is (I still may not). In this regard, I think the the tutorial is either outdated or unclear or wrong. Before building it a fourth time, I searched on the error and found this https://stackoverflow.com/questions/45377621/error-cannot-resolve-symbol-edittext-in-android-studio-myfirstapp-tutorial (https://stackoverflow.com/questions/45377621/error-cannot-resolve-symbol-edittext-in-android-studio-myfirstapp-tutorial) which was not a turnkey fix but was enough information to successfully complete and run the app.

    I spent almost as much time getting a USB driver to run and work on an old Win7 box. Seems like I spin the same wheels every time eventually beating it into working.

    The screen is nice. I have yet to root the machine but I only tried once (KingoRoot).

    I never did anything with Android programming before so I can only say that if you want to get your feet wet, this worked for me. Not sure I even know enough yet to recommend Android Studio but it does work. Kotlin or Java - dunno, I went with Kotlin so far.

    We'll see, next up (at least on the list) is to find some BLE devices.

    Just search fiber laser engraver on YouTube, and I don't see many use this in an enclosure.

    FYI, those are marketed in China for use in the open public, for engraving souvenirs on street side markets or tourist destinations.

    Sounds scary, but so far no reports stating they have blinded anyone.

    Again, I need to stress the fact that those lasers are NOT collimated. They use a technology called f-theta lens, which allows for large area engraving without losing focus.

    Essentially, the more the light bends, the longer the focal length is, so effectively at the same vertical distance it is always in focus, regardless what the hypotenuse length is.

    However, once the vertical distance changed, it goes out of focus very quickly.

    Typically you get ~3mm of travel before the laser loses enough focus and loses capability to do any damage to even organic matters, and for metal engraving, ~1mm, and I will be at least 30cm from it when it runs.

    Before the F-theta lens you have a collimated but expanded beam (expanded to protect the galvo mirrors from burning in due to the very high peak powers), and the F-theta lens refocusses the expanded beam exactly at the same height everywhere on the working area of the lens. Due to the very fine focus the peak power / area is enormous, which causes the material to vaporize.

    If for example the beam before the f-theta lens has a diameter of 8mm, and the working distance of the F-theta lens is 200mm, then the reflected beam will have again a diameter of 8mm at 200mm reflected distance.  Remember these laser can generate pulses in excess of 10kW, which takes quite a distance for attenuation even if the beam is not very collimated. Laser safety glasses typically of an OD of >6 (attenuation of 1 million) for a good reason!

    I can imagine as long as the engraved object is perfectly flat, this probably creates no major issues as the beam is reflected back towards f-theta lens. But if the marked object only slightly refocuses the reflected beam is your direction, I cannot imagine safety is always guaranteed.

    Apart from videos on youtube, I have never come across one in industry without a safety cage. Agreed, I have not seen hundreds of laser marking machines in my job, but I have come across at least 25 of many different brands. That why I asked if you are aware of any datasheet from a reputable company that states one of their products can be used without a safety cage. 

    I would still recommend to be careful, and to use a good quality pair of laser safety glasses for you and anyone nearby.

    I looked into that as a result of your post. I looked into the genuine TinySA (genuine spelling of spectrum). It's only US$50! This, right? http://www.randl.com/shop/catalog/product_info.php?products_id=75243&osCsid=ha9cd162ojp4v041la6a18bv47 (http://www.randl.com/shop/catalog/product_info.php?products_id=75243&osCsid=ha9cd162ojp4v041la6a18bv47)

    Hard to resist the cheap Chinese stuff. I've got an decent HP counter, but with a crap reference, so I use an external ref. Wanted a second counter for my day job (since my employer has only one counter for many engineers, and no good reference). I was going to build one, but saw this on eBay, and it wasn't worth the time making a better one. The reference alone in this thing is something I get $25 bucks for on eBay, and the counter was $130 shipped from US. It's a BG7TBL FA-2. As received the internal reference was only 0.11 Hz different than one of my rubidiums. Tweeked the adjustment pot to bring it closer.

    Still using my HP33E on the bench so I should not complain too much.
    RPN rules.
    Too bad most engineering graduates I meet have no idea. On the other hand, my calculator does tend to stay on my desk and they are stunned I finish a calc sooner than they do.

    RPN for the win! I have three HP10 series calculators on my desk, my wife uses 12C's exclusively, and I think I still have my original HP35 and HP55 in a box somewhere.

    EDIT: Almost forgot the HP11 emulator on my OnePlus cellphone, too.

    Someone once asked to borrow one of my HP calculators. I waited for the inevitable "Where's the equal sign?", then told them it was in the battery compartment. Being one of the original series, its triple-NiCd pack fell right out... depowering the calculator... yet they still searched in the compartment for the equals key. :palm:

    RPN everywhere, all the time. Accept no substitutes.

    yea you need to treat a 4 inch thick piece of granite like a non stick frying pan for steel and clean it only with ammonia. And its not compatible with aluminum despite being a giant piece of rock. and you can only place things on the edge and slide them over and everything you need to place needs to be cleaned with a sharp clean flat stone.

    the whole concept is a massive WTF

    its also super hip to use it as a coffee table at work. I assume the bacon egg and cheese aluminum wrapper is a bigger hazard then the bacon grease and ketchup. It's like charging your phone with a jospeh junction to be extra toxic. I hope those were fake youtube comments I read.

    I bought myself a wood router for some upcoming wood work projects (including a kitchen renovation). After weighing pros and cons for a long time I settled on the cheapest model from Festool instead of a cheapy for $50. I already have a Festool circular saw (which was a gift) with guide rails and those guide rails can be used with the wood router too. The circular saw is a joy to use so I opted to cry for a day and enjoy a good tool from then on rather than being annoyed with a tool which just doesn't work very well.

    I got some high CRI LED strips from Cutter. It's the SSK-1560ZGE-50299NIC (https://www.cutter.com.au/product/ssk-1560zge-50299nic/) model. CRI average of 99 with an R9 value of 94, this is probably as close as it gets to sunlight. It uses the Nichia 757 Optisolis series for applications like museums/art galleries. Very popular with the horticulture crowd too.

    Hmmm fairly pleased with it, I will have to make some heatsinks and drive it harder to see how it performs. I'm actually surprised on how well the NEC quad phosphor tubes perform, they were well worth the extra money compared to normal fluorescent tubes.

    I'm still searching for something that can perform as well as my headlamp modded with a Nichia E21A 4500k R9080 (in terms of tint, deviation from black body locus). A lot of stores tend to make things with the higher flux bins but they are too green which is a pain. The LED strips I got were a blend so it sort of helps alleviate the tint problem.

    I reaaaally don't want to resort to tint mixing with different strips because powering them might get a little complicated compared to just slapping them on a Meanwell LED driver. But the control I could have...  :P

    I accidentally found out AMOLED can visualize IR laser (presumably due to non linear frequency doubling effects), and I thought it was a good idea to use my phone to find the focal distance of my 8W freaking fiber diode module :palm:.

    You pointed a laser directly at your phone screen? If the laser is a 808/915/980 your phone camera will pick it up (sorta). Just use a white business card as a target and look at it through your phone camera. But beware, cameras are even more sensitive to lasers than human eyes so don't put the camera directly in the beam path and just look at the reflection. Used that trick with some 20W 980 diodes, worked like a charm.

    Same here. I get that exact package all the time.

    DigiKey has an amazing assortment of box sizes and shapes. Recently I ordered some large diameter heat shrink tubing and instead of folding or rolling it, they shipped it in a big tubular box. Still had the complete DigiKey logo on it and everything so it wasn't a one-off.

    FYI, our Production department buys large volumes from them and those shipments come in traditional larger boxes.

    Orico Bluetooth 4 adapter $11.30 Canadian after tax. Purchased so I can use my computer with a microphone as a phone without having to go over to where it is hooked by wire into something.

    I used the source from
    https://github.com/heinervdm/nohands

    which seems to only work with oss but works with the gnome desktop pretty solid by using the pulse to oss wrapper.
    So I just use 'padsp hfstandalone' whereas it is configured to driver oss and  /dev/dsp

    As a spin off I can now record phone conversations by using for example obs.

    Worst, after paying, kept making self excuse that maybe these will be useful someday in the future ... and was thinking hard, and suddenly the low distortion Wien Bridge Oscillator circuit that needs incand. bulb pop out, and what a relief to self that finally found a good excuse for the purchase.  :palm:  :palm:  :palm:

    The conflict might just arise from the fact that CO2 extinguishers are more effective indoors than outside. I've had training on both powder and CO2, outdoors (Did 7 months unarmed service at an airport fire brigade, as radio operator), and there is an art to putting out, say, an engine compartment fire, with CO2.  The general idea is to just open the bonnet enough to get the nozzle in and burst away. We also had an open "fire tray" of roughly 1m square with diesel sprinklers and a propane pilot flame. When turned to 11 it was a bit of a challenge with CO2. But I did it.

    Anywhere you want to keep going after taking the fire out, CO2 is preferable, of course, because the cleaning from having used powder is going to be more expensive than the damage from the fire. Best example is the kitchen, with electronics a good second.

    Ended up costing an arm and a leg to ship, won't be here for a month but I'm stoked!

    Combined multi-channel analyzer, pulse height analyzer, pulse area analyzer, and time histogram analyzer in one neat NIM module!

    It uses an oscilloscope in X/Y mode as display! It can directly interface PMT's or electron multipliers without preamp!

    Oh and there's all sorts of expansion modules for CAMAC, RS232, or GPIB interfacing.

    It's basically a catch-all instrument for alpha and gamma spectroscopy, XRF, time of flight mass spectrometry, cosmic ray astronomy and more!

    Hi everyone,

    New toys arrived ...

    A LM399H Voltage Reference, to check my two HP3456A. Preliminary test are promising on the twenty year old calibration of the two meters. I did also include pics from my custom un-calibrated one (using LM399AH).

    A beautiful HP 5326B with eight nixies (Opt 001), from Max K., this is the one spotted on his video BEB #125 https://www.youtube.com/watch?v=OG6Rf_7O5MY (https://www.youtube.com/watch?v=OG6Rf_7O5MY).

    A Goerz-Metrawatt SE460 recorder, it seemed smaller on ePay than when it was delivered... If ever anybody have schematics or service manual for it, feel free to share it, I did not find it :(

    All I bought was a Manual Coil Winder, was said to arrive next thursday but arrived today  :-+
    I need to rewind a transformer and make it 24V instead of 12V.

    Also I love that it's branded "Katsu" ... Japanese for cutlet/schitzel (https://en.wikipedia.org/wiki/Tonkatsu).  ;D

    Looks great! Is it 6-channel? Looks to have only 3 pens.

    I hope you have a source of pens and paper for it! They can be difficult to find nowdays. I ended up having to make custom pens for my plotters.

    It does have all six pens ! All with tiny caps, and only one is dry. But, the better is they are refillable as told by instructions on the "paper tray".

    For the paper it is still available for now, not so cheap (10€/roll), I ordered some. But you're right they soon will become unobtainium.

    I had to fix it, it had two faults, maybe caused by the possible short identified by Max :
    - the LSD nixie's current limiting resistor was burned (visible on Max's video at 5:19) probably because of a bad "0" in the tube, resistor replaced, and exchanged the LSD and MSD tubes (as MSD rarely display a "0") ; the fuse on the +175v rail was blown because of this also.
    - the -5V series pass transistor was open (it was reading -3.XXv because of some flow from the -16.5v rail) I replaced it with a BD139

    Manfrotto Magic Arm. Just realized how well they work as adjustable armrests when working above a preheater with a microscope at long working distance (bench at waist height.) I reckon it would also work well for holding a hot air gun with a clamp during rework.

    The Trangia of course can run on alcohol, too, and my stoves were bought with spirit burners and I've got them in storage, but the butane/propane mix is much more convenient. No soot, regulation worth talking about, and at least three times the power.

    I fell out of love with the butane-propane mix ones after a few camping trips where even after spending the night in the bag with me the fuel wouldn't vaporize enough to burn.  Of course you haven't lived until you have had a canteen freeze inside your sleeping bag.

    I suspect that proper cans work fairly well, but I have gotten quite a few that seem very heavy on the butane and light on the propane side.  Maybe just an effect of natural fractionation.  Works fine first time, but on really cold days the cans should lose more propane than butane so on a second light might be in trouble.

    A bunch of radio stuff recently, after I got my ham license:

    * A 2x used Kenwood TK-8100-1 25W UHF transceiver lot (very dirty and in the wrong band initially, washed and modded before use)
    * A used Kenwood TM-471A 60W UHF transceiver (also needs washing, but already in the correct band.)
    * An unbranded 435MHz antenna with coax and stand.

    I am downright suspicious of Butane Cans in particular opened ones in Cars in the Aussie Summer.  :o Even the shellite in the tank is a bit of a worry but less so. For longer Camping trips instead of just a Roadside Coffee I have more LPG burners BBQ's and ring burners than I can use Paella Pans for 120+ serves or a Hot Plates instead;)

    Day before yesterday, a Tektronix 2440 digital oscilloscope.  Not so sure I want to keep it but time will tell.  Supposedly 300 MHz but I measured around 275.  Agrees rather closely with my other test gear, regarding wave shape and frequency and amplitude.

    I haven't figured out if it does FFT or can smoothly vary sweep rate.

    A Venus Scientific LU15A. Apparently these were quite common for aircraft CRT's back in the day.

    I purchased a Mini-Circuits SCLF-10+ 10 MHz low pass filter and added SMA connectors.  I thought that I would compare the high frequency roll-off of that compared to that from BG7TBL's 10 MHz band pass filter.  The low pass filter (without the SMA connectors) is not that much more expensive--$13.94 at Mouser.  While the BG8TBL's frequency response is not bad, as expected the Mini-Circuits filter has a sharper roll-off.  That is shown on the first attachment.

    I thought that I would also compare two other 10 MHz low pass filters which instead have BNC connectors.  I compared the Mini-Circuits BLP-10.7 to Crystek CLPFL-0010-BNC.  The BLP filter obviously starts its roll-off a bit higher in frequency, however the Crystek filter has the lowest level of all four above 20 MHz.  See the second attachment.

    While the BG4TBL filter is just 44 dB down at 30 MHz as compared to over 62 dB for the others, that is still adequate most of the time for converting a 10 MHz square wave into a sine wave.

    Didn't buy anything today... Latest purchase was something off ebay that was local enough we tried arranging a local pickup (we are 5.6 miles, 9km apart), but had issues with ebay's messaging. So in short to make his shipping deadline, and he was going out of town for a bit so he had to ship it. That was January 4th when it arrived across the state. Stayed there until yesterday at one sorting office only to make its way further north to another sorting facility.

    All for a $9 purchase. 12 days, 157 miles /252.6km and its still nowhere in sight, keeping this trend looking like I'll get it 29 more days after traveling 480 miles, 41 days.... for a small box of 26 ICs from a guy that lives less than 5 miles away.

    The other IC lot is sitting in Atlanta still.. I don't want to talk about that one too.

    So, I bought waiting an ungodly long time... ... Originally I intended to buy some ICs for a project that is now indefinitely on hold. Sorry about the rant.

    I can relate. Mid-December I found a NOS motherboard for my new Win7 workstation build. The seller is in Virginia. We agreed on price, and he shipped it Priority 2-Day the same day. He sent me the USPS tracking number. I would have it in two business days. Online tracking confirmed it was "in the system".

    And there it sat.

    Stuck in a distribution center in Virginia.

    For three weeks.

    Meanwhile I had ordered all of the other components. I started to worry that their warranties might run out before I got a chance to even test them.

    I filed a formal complaint with the USPS. Got a phone call the same day, so I can't fault their response time! The story was that a combination of Christmas time shipping and COVID-19 absences meant shipping containers were parked in rows in storage areas, with nobody to unload and process them. He estimated it would be mid-January at best for Priority packages. Standard shipping wasn't expected to process until sometime in February. I would receive notification when it started moving again.

    Nothing else happened for many days, then I got a message. Not that it had finally started moving, but that it had been delivered! Sure enough, there it was in the mailbox. I've since assembled the system and it's working fine so far.

    So yeah, I can definitely relate to shipping delays. Even when you spend extra money for Priority shipping.

    On that note: I finally got tired of Rubing together various series-parallel networks of the resistor values I had on hand. Instead I treated myself to a full selection of those sample kits from DigiKey. Each one includes five samples of every 1% value in a given order of magnitude. I have every 1% value from 10R to 1M plus a few outside those ranges that have become necessary over time. Every new order I refresh the values I've consumed. There are a few I keep in 100's since they're used so often. This has made a WORLD of difference in breadboarding convenience.

    To a limited extent I've done the same with capacitors. The problem there is the wide variety of dielectrics makes it impractical to have every value of every type.

    Obviously this isn't practical for IC's and discrete semiconductors. But it's been a huge time saver and convenience multiplier. Like my Hakko FR-300 desoldering gun, I only wish I hadn't waited so long.

    One of my latest purchases has arrived. 6 days late. Got a score of old ICs off an ebay "estate sale". Lots of mid-late 70s vintage. Also had a 8080 cpu in the mix too with a lot of other related peripherals. I haven't checked any of these 8000 family chips (i could only read one in the original listing picture) but a few of the other logic chips checked good. Almost 200 ICs total. Spent 30 including shipping. Mainly bought them to play with since I used to have hundreds of ICs before I had to purge (long story, but it happened when I was a teen. I'm over 40 now).

    My highschool auditorium had a large three-phase model of that for lights; installed in the early 70s, IIRC. Absolutely hum-free dimming, and a wonderfully smooth curve. I used to point this out to the thyristor dimmer fanboys, saying that there was a method of not contaminating my sound system...

    There can be only one!

    There are, in fact, not only one , but several Swedish axe brands. The one Bean posted is a Hultafors (https://www.hultafors.com/products/axes), which is probably the largest hand tool company in Sweden that has not been bought by a multi-national and then been brand-raped.[0] Their hammers are legendary; I own both the carpenter's and the electrician's models from them. One feels twice as strong and hits more often with them, compared to no-brand shit.

    The most "hand-crafty" axe-makers with market presence globally probably are Gränsfors Bruk (https://www.gransforsbruk.com/en/) and Wetterlings (http://www.wetterlings.com/), but I'd argue that the Hultafors is pretty close to them in performance.

    Hultafors brought Hults Bruk as part of their portfolio and the heads come from there. In Oz branded Hults Bruk Axes run twice the price and for Bush use OTT the heads are still stamped Hults Bruk :) Hults Bruk here http://hultsbruk1697.se/ (http://hultsbruk1697.se/)

    Our local big box hardware chains sell nothing but crap  :-- I did the rounds of the local Chainsaw/Timber type hangouts and apart from having no flaming idea they also had no stock. Way back into the dim dark ages of my working life I worked for a company that was a Stihl agent and we sold Axes and a range of Hickory handles but the small chainsaws seem to have taken the place of axes in forrestry.

    Lol, there are even original cable twist ties inside.
    Oh and an unopened envelope with floppy disc for the fluke view software  ;D
    I am curious if the battery is still original, as a quick test today gave me an impression that there is still a lot of juice in it... Will see tomorrow when i test it in field...

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1159094;image)

    I know these are cheap (try not to laugh). I did some due diligence (I hope, successfully). I looked at some videos, including some that included tear downs.

    I have a rather nice Dremel 4000 with speed control and a workstation/ drill press and a flex shaft. I think it is quality equipment for my level. The problem is that I do not have an unlimited amount of space. If I just want to do some small thing (e.g., drill a single hole), it is a pain to dig it out and set it up. That's fine if I am going to be using it for a while.

    I also have these two drills, which are both decades old. Neither has speed control. So that is why I bought this.

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1159098;image)

    I recently received five Rakon VTX0225AR 10 MHz VCTCXO's.  While I did not need GPSDO precision, these came closer to that than I expected--0.05 Hz drift during a recent 3.5 hour test.  See the first attachment.

    The second attachment shows the oscillator board with its metal cover removed and terminals labeled.  Another picture floating around has those terminals incorrectly labeled.  Besides having a trimmer capacitor available for adjustment of its frequency, it has a control voltage terminal where the frequency can be more finely tuned.  That is how I adjusted the frequency to that shown on the first attachment.  Even with the trimmer capacitor set for the highest frequency possible, it seems like most or all of the units do not quite make it to exactly 10 MHz.  However, it is obviously possible after adding the voltage adjustment.  Accordingly, that voltage adjustment only seems to raise the frequency.  Via a fixed and trimmer resistor combination, I have the electronic frequency adjustment range set to 10 MHz +/-10 Hz.  That makes fine adjustment easy via a 25 turn trimmer.

    The VTX0225AR has a clipped sine wave output.  Attachments show that on my oscilloscope and spectrum analyzer.  While ALL harmonics only go down slightly at higher frequencies, I saw almost nothing in the way of modulation products or IMD very close to its 10 MHz frequency.  While it is possible to add a bandpass filter for using one of those harmonic frequencies, the last two attachments show its output with a Mini-Circuits SCLF-10 10 MHz low pass filter connected to the oscillator's output.

    What do these things cost?  How about $2 each?  A quantity of five is available on eBay for $10.  See: https://www.ebay.com/itm/232248869943 (ftp://www.ebay.com/itm/232248869943) That auction confuses things by highlighting the oscillator's reel number rather than its part number shown in the pictures.

    So far I am very happy with the purchase.

    I was expecting a horror show on the inside for the few $ but actually not to bad at all. Large chip on the display board is a Holtek LCD driver. Unbranded micro on the mainboard and some reasonable hardware. It has 4 independent chargers unlike some which are two pairs, it also runs a slower charge rate for AAA's over the AA's. Case is fairly tough and having everything screwed together  :-+ :-+

    With fingers-crossed, I bought my first eBay for-parts-only test gear; an E3611A power supply.   The seller noted that the voltage bounced around regardless of setting.  After watching a few YouTube repair videos and studying the schematic, I knew they were quite fixable by having few custom parts.

    With the top off, it was readily apparent that the bulk caps in the bipolar power section threw their guts out all over.  Measuring the test points showed that it was far below the required +/-12V.   After desoldering the bad caps, the nearby bridge rectifier and trimmer pot I cleaned up the mess with ipa.   That goo gets under the green mask and eats the traces/pads to the point of breakage!

    After re-tinning the bare/missing traces and replacing the components, it worked!!!  Woohoo!!!   With my DIY analog load attached, the power supply's readout tracks bang-on to the multimeter below it.

    The 3478a meter was also an eBay find that I'd acquired a year ago.  I've documented the battery replacement elsewhere on this forum.

    Overall, I'm finding that I browse eBay a little too often lately.  Hmmm....

    More arms for the bench
    Monitor Desk Mount Arms  see
    made from die cast aluminum in gray metallic paint with allen key adjustment by grub screws. with some black phasic cosmetic end caps. 
    the hinges have fat steel pins in steel bushes pressed into die cast aluminum arms.   
    this benchtop arms are at the cheap end of the scale. lacking any vertical spring balancing or USB ports.
    so are not prominently listed on the offceworks site.    Australian office supplies stores.
    my bench image see \/  has a notch in the end plate, this is part of the die cast aluminum.
    decorative lines set into the cast aluminum. not photoshop!
    other image is of images from the offceworks site.
    ready-to-assemble  desk mount kit also has two steel plates so the temporary bench clamp can be made a permanent attachment
    by drilling a hole through the bench & adding 6 wood screws.

    I am one of them DIY hobbyist's that has five projects on the go at the same time.  :palm:
    however only one completed.   :-\
    so when bench real estate is at a premium, a way to find extra bench space is essential.
    an old dentist chair with its many arms is a bit too expensive.  ::)
    however local office supplies has this desk mount twin benchtop arms for pc monitors.
    the two benchtop arms can hold up to 8kg x2 and swing out to 30cm from a 35cm high upright stand.
    one can hold say the oscilloscope,  the other a pc monitor or set of DIY DMM cradles.  16kg
    all up off the bench. needing custom DIY cradles, however this is another project,
    so time will tell when all is gets done.

    You have found the path to enheavyment. It is downhill in the most intriguing way. Here's my latest arrival; sold as for parts. It needs a new Rifa bomb, a fuse for 240V operation,  a few dents in the casing straightened, and a cleaning. I've swapped the US plug for a C14, and reconfigured it for 240V operation. Not powered yet (waiting for the Rifa). Now I only need a higher-voltage DC supply (perhaps 300V) and I'm good.

    For a while.

    When we remodeled our lower level we plumbed a hot water spigot to an outside wall for exactly this reason. Now we use our existing Harbor Freight pressure washer with hot water straight from the water heater. Granted this isn't "portable" away from our house but we don't take our pressure washer on the road anyway so it's a perfect solution that works with any unit today or in the future.

    This could be a solution to two problems.  Here in the US the drain valve on water heaters almost always has a hose bib (water spigot) outlet.  And it is supposed to be drained annually to minimize problems from scale and sediment.  That annual draining is one of the most neglected maintenance activities there is.  Hooking up your pressure there kills two birds with one stone.

Granted this isn't "portable" away from our house but we don't take our pressure washer on the road anyway so it's a perfect solution that works with any unit today or in the future.

    This could be a solution to two problems.  Here in the US the drain valve on water heaters almost always has a hose bib (water spigot) outlet.  And it is supposed to be drained annually to minimize problems from scale and sediment.  That annual draining is one of the most neglected maintenance activities there is.  Hooking up your pressure there kills two birds with one stone.

    At first brush it sounds like a great idea, but on further reflection I can't imagine that the sediment would do the pressure washer pump any good.  Might literally kill one of the two birds...

    A hot water pressure washer.Have not had one for a few years as I have been using a cold water one but hot water is so much better that I bit the bullet again and purchased a diesel fuler hot water washer.

    One: only use a hose that is rated for hot water. Some cheap garden hoses will quickly burst at the crimped couplings.


    Two: do not even think about doing this to your pressure washer.
    I got rid of the hot water tank last year and installed a on-demand system.
    On draining the tank the amount of junk that came out clogged the mesh at the bottom of the sink. No mention of the colour of that water either....

    The other bit of maintenance people forget is to change the sacrificial electrode in the tank.
    Someone on my street I know was denied insurance compensation when his tank leaked during vacation because he had not done that....
    Word spread quickly about the said company!

    Water heaters have their outlets at the top of the tank. (The inlet is usually at the top too, but has an internal pipe that extends to the bottom internally so cold water enters at the bottom nearest the heat source.) Thus the outlet draws water from the top of the tank, away from sediment.

    The tanks have a separate, dedicated drain at the bottom of the tank, so when the tank is flushed for sediment removal the water exits at the BOTTOM and takes the sediment with it.

    Thus:

    * Running water from a water heater does not risk an undue degree of sediment running through the pressure washer's pump

    * Running water through the pressure washer would not properly drain sediment anyway

    The correct way to drain a water heater for sediment (or movement of the tank) is to hook a hose to its drain spigot, make sure all other hot water faucets are closed, and then open the spigot. Fresh cold water will enter (and be taken to the bottom of the tank by that internal tube), and hot water full of sediment will exit through the spigot and hose. Note this process means you don't have to drain the full capacity of the tank to flush the sediment... once the water runs clear you can stop draining because the water circuit is from the bottom of that internal tube to the spigot, a small percentage of the total height of the tank. You're not really "draining" the top portion of the water column anyway.

    Right, but the earlier discussion was about connecting the pressure washer to the drain valve, not the regular hot water outlet - thus the 'killing two birds with one stone' statement - hot water to the pressure washer and clearing the tank of sediment without wasting the water being drained.

    I will stand by my suggestion with a couple of caveats.  Depending on your water sediment can accumulate too rapidly to make this sensible.  But in other cases little sediment will develop in a few months or a year.  If you don't drain the sediment bedford it gets deep you can't drain it anyway.  If the sediment quantity is a problem for your pressure washer there are many in line solutions,.or you just drain the sediments before connecting the pressure washer.  The point of this is that it saves installing a special tap (with the heat wasting plumbing associated) and give a reminder to do a necessary maintenance job.

Well, turned out there is not much to see (literally). Even at maximum magnification it's tiny. The datasheet says it's 0.73mm×0.64mm. Well, is that "half a bee's dick" size?

    Apart from that, I have one or two hundred parts from various distributors that I'm yet to sort :(.

    Recent purchases are the standard requisite bundle of circuit boards, components etc

    I also got a bench press drill, and I am now looking for a vice to fit to it that can handle holding something 75mm but with soft jaws. Ordered a sliding one, but it had far too much play on the bottom slider, so it is getting sent back.

    Got one of those NS-100 soldering irons with the directly heated tips from Amazon.co.uk, and I am quite pleased with it. Flashed it with updated firmware and got a larger tip, and it is much better than my old soldering iron (60W Maplin digital temperature controlled Hakko FX888 style). It came with a 24V power supply and a C2 tip and was £55 delivered.

    Tip heats up very quickly and maintains a set temperature much better than my old iron.

    I made a haul today of stuff being thrown out at work. Most things are still at work. First to be checked checkout: 2 Astro radios, 8 batteries, 2 chargers. I'm charging a battery to see if the radios work. They are in very good condition. I was at the first meeting for engineers at Motorola in the 1990s when they talked about the Astro program. They didn't quite know what it was yet, just digital and next generation encryption. I was working on a parallel program that ended out being used for an initial prototype platform. RF front end was dual convertion to 455kHz, but the 2nd IF was fed into an IC developed in research that spit out digitized I and Q. In my program, we fed that to a 56000 family processor. I have no idea what's inside these newer products.

    Heathkit IO-102, I ran out of functional scopes a while ago and this was $20 (complete with the build manual!) and down the road, 5 MHz single channel is good enough for most of what I'm into anyway. Mostly works, builder did a semi acceptable job, acts like the HV and maybe lower rails are low (haven't measured yet) but all the bigger carbon comp resistors on the power board and in the HV divider have drifted up 50+%, so that and a couple electrolytics should put it right. Came with graticle, I just pulled it off for cleaning.

    It claims to have an auto sync function that sorta works and has some set and forget adjustment procedure in the manual, I intend to do a full alignment after the quick refurb. I'm sure I could cook up a better trigger if need be.

    As for blowing out the front end that's part of the appeal of it, the entire BOM of the vertical amp in this thing can't be much over 10 bucks in jellybean parts. I might keep it after acquiring something nicer just for poking places I probably shouldn't.

    2 x soviet VEU-6 channel electron multipliers (chenneltrons)! These are strange little ion/electron detectors for mass spectrometers and electron analyzers. With original datasheets and test data.

    I also got 2 Ortec VT120C fast preamplifiers to amplify the output pulses.

    I found this old paper that uses 2 channeltrons as a Time-Of-Flight mass spectrometer. A channeltron can apparantly also be an electron source if you shine UV light or beta particles at it!

    Alas, I'm right-handed, and keep my mouse on the right side of the keyboard, so the touch pad is really on the wrong side for me.  But the fact that this keyboard is narrower than full-sized keyboards, helps.

    If it does not work out, I can always donate it to a family member who has a media center but no wireless keyboard for it.

    A Logitech K400 Plus keyboard with integrated touchpad instead of a numeric keypad:
    I have two of them. One in the Bedroom works great and the other on my Laser is fine for tweaks of designs or cutting profiles but as an everyday keyboard not so much.
    I also have one and it works well, although i don't use it for everyday typing but instead on a media computer. The small form factor and the excellent wireless controller are key features for me.

    Firewood

    Have you heard about the mad chainsaw man?--------ohhh!

    Seriously, though, I used firewood till the winter before last, although mine came in the form of "split jarrah"blocks (actually more like "lumps").
    The "blocks" were often a lot larger than my fireplace, so I had a manual "block splitter" (hybrid between an axe & sledgehammer) to reduce their size.

    Jarrah has delusions of grandeur, is not content with just being wood, & aspires towards iron, so it is great exercise splitting it.
    As I am seriously past that stuff, we now have a "reverse cycle" airconditioner which also cools us in the Summer!

    Splitting hardwoods like Jarrah is an art in itself.  ;)
    Dad taught me the backing off method where you continually go round and round the circumference taking off slabs around the growth rings until you get near the center of the block where it can be more easily split.

    Still, firewood warms you 3 times, 1st when you gather it, 2nd when you split it and then finally when you burn it.  :-DD
    It's still one of life's simple pleasures as nobody dares annoy you when wielding an axe.  ;D

    Faster with an axe especially when you have a small firebox.

    My son has a Fiskars splitting axe and at first glance one calls them as too lightweight for big wood but my do they really perform parting blocks effortlessly and with a weight you can happily handle for extended periods.
    I first thought it a toy but I can assure you it's not.

    I have to confess, for the last few years I have hired a local to saw them up for me and split them with a hydraulic splitter on the PTO of his tractor. This is 'assignment' wood, which I get as a right of common attached to the property where I live. The woodland is managed by Forestry England (formerly the Forestry Commission) and they fell and stack the assignment wood. It's up to us commoners to arrange to collect it. I used to do it myself, but now it's all mechanically handled the logs are 2.2m long instead of the old 4' cordwood length. That makes them Too Heavy.

    That lot will be sawn, split & stacked in the next few weeks. It will be seasoned under cover in stacks for two summers before it's used - that's at least ten warm, dry days  ;)

    Nice nfmax.  :-+

    We have enough storm damaged trees each year to provide us with firewood and we need only collect it from around the farm into a stack for the following year when we park the tractor driven firewood saw next to our wood shed and flick each piece into the shed as it comes off the saw which can manage 6" logs although as I age they are no longer 6' long so to save my ailing back. Up to 4" and 6' long is fine and with tractor power behind it the blade is through them in a split second.
    6" and larger requires the chainsaw for which I have a few some of which some are just too large and unwieldy for blocking wood but perfect for felling big wood of 3' or more.
    As the winters here are not frigid cold or excessively wet the daily job is to fill the barrow with sawn smaller and split larger wood for our small log which is enough to both take the chill of the house and heat our water.

    Cat just loves winters.

    70 SMT diodes...

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1177420;image)

    ...because I needed one of these...

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1177424;image)

    ...because I "chose" to believe it was ok to have Vcc connected to GND. I chose unwisely, as upon applying power, the original diode glowed brightly for a moment and then emitted a wisp of magic smoke. "That can't be good", I said. Sometimes I surprise myself.

    Why did I buy a selection of 7 Values (10pcs/ea.)? Because the total price was US$6.99 but no shipping charge

    $6.99 would not even have covered the shipping charge at a reputable place like DigiKey.

    All ended well as I managed to kludge the replacement protection diode and everything works...again...for now :)

    I bought in some pcb's from JLCPCB for a transistor matcher and curve tracer.
    Its basically just an inverting transistor stage.
    I apply a ramp to the base and monitor collector voltage.
    Base voltage and collector voltages are stored in array's for use by the pc.
    They are then plotted on the pc screen for comparison.
    The pc also displays hfe at any point along the curve by moving a pointer.

    Today, I got my long awaited parcel from Japan- and upon opening, a Der EE De-5000 including accessoires fell out- and some new scope also found its way on my bench.
    The Rigol DS1102Z-E is the 2-channel sibling from the 1054Z, that sports 100MHz and is somewhat cheaper- here in germany you can get them for aroung 260 € incl. sales tax...

    Note that on the last pic, focus was on the middle of the cases, so due to a shallow in-focus area the displays seem to be a bit blurry- this is due to photographing with an open aperture...

    The DE5000 can use silastic inside of the 2-kelvin connected alligator clip probe, the plastic box has wires soldered to a PCB and i got a short circuit from using it (the sense shorted inside of the enclosure). The strain relief they used for the application is insufficient, particularly because the leads are short and the meter is often in a very awkward position  (just a zip tie).

    My latest most interesting purchase was an AIM-TTi i-Prober 520. What started as an end of year purchase, has turned out to be a really nifty tool.

    The first real application came mid-January with a prototype that was drawing too much current. My first idea was to fire up the thermal camera, but then I remembered this purchase.

    It is fascinating how one can follow even a current of a view milliamps through trace junctions. Within minutes I could single out the culprit from of a handful of suspects.

    I have been using this tool more and more often. Great addition to my lab. I even build a small power supply cable with banana plugs and voltage reversal protection, so I can power the probe from a 5.2V auxiliary output of my power supply AIM TTi EX354RT).

    Indeed :)

    We make our own peanut butter now (typically 1.2kg at a time) and then when it's spread on whatever manually mix in Marmite. Or whatever own-brand clone we find in the shopping bag once home. It's kind of interesting in that the peanut butter can be quite fluid but adding in a small amount of Marmite makes it set like concrete. In fact,  I once figured I should just add Marmite as we make the butter, and that completely trashed a blender as the mix set...

    The DE5000 can use silastic inside of the 2-kelvin connected alligator clip probe, the plastic box has wires soldered to a PCB and i got a short circuit from using it (the sense shorted inside of the enclosure). The strain relief they used for the application is insufficient, particularly because the leads are short and the meter is often in a very awkward position  (just a zip tie).

    I will make some experiments by using short ordinary 4mm cables with probes that have a tip- in howfar the measurements will differ...
    Oh, and to brag a little bit: Got the meter and all three probe adapters incl. customs tax etc. by importing it from japan myself for 130 € - so if anyone wants to get some, it seems a good time to do so ;-)

    There are several project videos available converting the alligator clip housing to full Kelvin connections, usually by swapping the cable. There's also a 3DP project on here somewhere to print a new housing for 4x BNC connectors, using an extra thin PCB as "wedge" into the "Kelvin gap" on the meter.

    Yes, it's a fantastic little meter, really useful on the bench.

    I bought a Sony DPT-S1 e-reader thing. I'd been looking for one for a while, but they are pretty difficult to find (in Europe at least) for a decent price. I have a standard sized e-reader with all my datasheets / docs stored on it, but A4 pages are unreadable without zooming and scrolling. With the DPT I can reference the datasheets a lot more comfortably.

    I found out the SN-28B isn't "The One" as far as crimpers for the header pins. After more research "The One" is the Engineer brand PA-09. It simply does the job better than the SN-28B crimper you see sold with a lot of sets. Even though the SN-28B does both crimps at the same time, they aren't as perfect as the PA-09. So now I have one.

    I really like sensors. Always have. I know well that the accuracy of any sensor depends on your ability to evaluate it against standards. To be sure, a sensor can still have some utility in the absence of such evaluations, but I know that one should never forget the dependency on standards.

    Further, I would state categorically that I would not recommend that anyone go cheap with any safety product. That being said, I picked up one of these:

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1189336;image)

    ~US$30 https://www.amazon.com/Portable-Natural-Detector-Combustible-Flammable/dp/B08MDX5F1C (https://www.amazon.com/Portable-Natural-Detector-Combustible-Flammable/dp/B08MDX5F1C)

    I tested it out against a gas stove; quick lit and extinguished and held on for a few seconds without lighting. The product has a decent response and that was encouraging.

    I tested it with an open bottle of 99% EtOH and it also alarmed.

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1189340;image)
    Close inspection reveals that the sensor is a Winsen device - my guess is a ZP04. Not sure if/when I will break it down.

      Fan very high pitch and noisy.
      Looks like some damage to Enter switch on front panel.
      Remote interface optional.  IT7321 (BK9801) had LAN, USB and RS232 as standard.

    And an uncomfortable buzz during power on. Also, fan quality control is bad, some are quieter, some are noisier when output is enabled but not loaded. We have three of those, and they all sound differently.

    Otherwise the electrical performance is good, the size is small, and the price, nothing beats free gears. We got them for free, so nothing to complain about.

    Damm, just noticed Power factor is only 2 decimal places,  IT7321 (BK9801) had 3 decimal places,  the spec I'm working to says I need greater than 0.99  power factor, so 3rd decimal place is important to me believe it or not.  Blueskull, do you know if 3 decimal place for PF available through remote interface?

    As I am also doing some work on a breadboard (and an Arduino is also waiting for me) some 4mm to Dupont cables were very nice, so that i can put those directly to my multimeter.
    I also got a BNC to dupont cable for connecting that to a scope.
    And some small nifty adapters to connect some wire to BNC, that my scope can be happy too  8)

    I ran out of small heatshrink tubing again. So decided to fix that once and for all. Bought 50m (10 x 5m) each of 2mm, 3mm and 5mm dia heatshink from an Aliexpress store. This will be a lifetime supply. No really, it will, I'm 65 and can't imagine I'd use this up.

    It arrived today. In a remarkably small package. I wondered how they got it that small. On opening, turns out they tightly rolled each length and stuffed it into a small ziplock bag. Pretty clever way to minimize postage cost.

    But... the result is a crimp in the tubes, every few cm. Rats... It's not _important_, the crimps go away when shrinking the tube, but they are annoying when cutting a lot of short lengths and fitting on wires, etc. Oh well. Now I have a lifetime supply of annoyingly crimped heatshrink.

    The longer they're left in the little bags the worse the crimps will get, so I unrolled and large-bagged them all. Took a while. I'd have rather paid a bit more for postage, and received it in natural-curve sized rolls.

    Only in countries where labour is borderline free will this be a sensible way to get an edge on the competition. Especially since it does nothing for the weight, and I assume that, postal-rately, weight still trumps volume when the sleeve is expanded to its natural circumference.

    Food for thought. I am not without guilt -- I just managed to get 50 DPDT toggle switches for 1/4" hole, from China, where buying them from someone like Mouser or even TDM would be prohibitively expensive for my renovation project.  Am happy, though, that they evaded the customs fees (of which not the import VAT but instead the handling fee more often is the prohibitive one) somehow.

    Another purchase turned up yesterday, 5 T-shirts from the UK. UK mail and parcels get worse handling than China since 2021-01-01, so on top of 2-week delay, was slapped with VAT and import handling.

    But it sure must be good for business to be liberated from the tyrants in Brussels. Oh, yeah.

    I just fetched a late (1989) HP5335A Counter in nice working condition from 20 km away for 285 Euro.
    It runs both, short and long self test without problems and shows the GPIB "Addr." with the ".", meaning it has the newer firmware.
    the Pabst fan is roaring like a V8 engine but delivers a substancial airflow.

    The power button needs re-gluing but I have it at least. Any tip what glue would be best? Hot glue, epoxy, ...?
    Edit 15.03.21: Meanwhile I managed to drill and cut rests of the white bar out of the button. The remaining bar had a short length left to stick into the button. So it was easy to mount with a little hot glue.

    The picture shows a 1 kHz sinus signal from Siglent SDG 2042X.

    Got a NanoVNA V2_2 S-A-A-2 from Nooelec. I have HP VNAs, but wanted to see what it is capable of. Description said 50kHz-3GHz, but it lets you sweep to 4.4GHz. First glance looks like it will be VERY useful if you:

    1. only use the load and short cal pieces (the ones that came with mine are good)
    2. skip using the open (I don't understand it. better to leave port1 connector open when doing open cal)
    3. never EVER use the "thru" cal piece. ALWAYS use mating connectors for your intertable DUT. If your DUT isn't insertable, make it so by adding an adapter, not by screwing up your calibration.
    4. put an attenuator at the end of your port2 cable  (the match of port2 isn't great).

    It was $2,776.00 AUD plus 10% GST and $25 shipping.  From local agent here in Australia.
    I sort of wish I had bought the older model IT7321 (which is the same as BK9801) now.  The newer model IT-M7721 has some additional features such as THD measurement and waveform generation, but the PF reading on front panel is only 2 decimal places, remote connection is optional extra and fan noise is terrible.  Trying to sort these issues out with the local distributor now.
    I went back and had a look at original quote from the local distributor and it says:
    "The above products are indent items.
    Indent items cannot be cancelled or returned once ordered."
    Not much advantage in ordering from these local distributors (with what I'm guessing is a huge markup) if it can't be returned anyway.  Not sure what the price is in China, but even items from tequipment.net in the US are often a lot cheaper than the local Australian distributors prices.

    Yo, long time since I've scored.

    I've wanted a Tek 11801 since I passed on one two years ago. A friend told me about an 11801C in the SF area so I bid on it and won for $175.  It presented on ebay as super clean and it was.  What I've found in two of these now is that maybe due to the size of the frame, things have a tendency to work loose in them. It had an error we misread as easy but it turned out to be a time base issue that could have been a nightmare.  I started reseating cables, cards,  etc and when i got to one of the last ones, all of a sudden it booted clean.  I reran the diagnostics a few times and it's been clean since. The same friend, a great guy, sent me a module from the one I passed on originally that he bought.  I then found an SD-22 module for cheap, that worked well, so for cheap I'm up to 20gig. Sampling has limitations but it has value for the price I paid.

    You might note from my approach above that I rebooted or ran diagnostics frequently during the cable reseating.  I think it is important to do this for a couple of reasons. One is incase a new problem shows up you will note where you made the last adjustment or cable moved.  2nd, if you fix it, it is also valuable for the future as these problems might come back.

    Decided to bite the bullet and upgrade my (very) old UT60A. Ordered a Brymen 867S and some Probemaster leads.

    I didn't want to feel like spending more money in a year or two, often that is a false economy.

    And its big brother


    (https://download.schneider-electric.com/files?p_File_Name=SPD_MMAE-7V3QJB_FL_V_520x520.JPG) (https://www.apc.com/shop/uk/en/products/APC-Smart-UPS-1500VA-LCD-230V/P-SMT1500I)

    I was reminded by yet another 10 minute power outage the weekend before last that power here is not all that reliable, we get a short outage every 3-6 months and the occasional longer one.

    The 12V one has about 30Wh of 18650 li-ion (4x2200mAh) so should keep the modem powered up for anything up to 5 hours. The APC unit (bought 2nd hand from eBay) has 2x12V 17/20Ah - so about 408Wh of battery and will run the NAS/server, firewall and phones for about an hour. Haven't quite tested it to full battery discharge but it had about 30% battery left after 47 minutes so I think the full hour should be no problem.

    I do find it a bit frustrating that UPS marketing concentrates almost entirely on output power and not runtime - having to buy a 1.5kVA/1kW unit just to get decent runtime for a 250-300W load is overkill, especially as it has a much heavier autotransformer than I need (these "line interactive" units regulate under/over voltage by choosing the appropriate taps).

    Hi,

    Last week, I received a nice HP 5210A Frequency meter. As usual with equipment from this period, it needed cleaning of the rotary switches (with IPA). Once done, it worked great !

    And, today, postman delivered me a HP 339A Distortion measurement set that was lost since February the 4th... Package was in bad shape but the instrument was well packed. Just one broken binding post.
    The "meter" portion was not working at all, the culprit was a diode bridge having one side open. Capacitors seems in good condition. I'll now spend some time cleaning it's switches.

    You should be happy with the price of your JBC. The 34465A I bought in 2015 was AUD1,800 and it has now risen to AUD2,600.  ;D

    Well, as I don't have any suitable connectors for them, they will be used as micro-soldering practice boards, or returned to the great void  >:D. Of course, if some one needs a couple or more, please PM me.
    Unfortunately, the whole assembly is a diarrhea of unobtainable (4me) micro-mezzanine PCB connectors  |O.

    Today a Avo DCM 300E leakage current clamp meter turned up for 45€ posted.
    It came with a early '90s look to it although the box is dated 04/02, the Toshiba LR44 batteries must have been the original ones and had leaked a little.

    It's a rebrand of the Japanese made Multi M-140.

    A Mantis Elite arrived this week, currently clamped to the front of the bench whilst I figure out the best place to permanently mount it.
    I think I may end up with a 2nd base plate so be able to move it between two work areas.  I try to keep soldering / hot air away from where I have stuff under test hooked up to instruments and the PC. 

    Stunning to use, wish I'd bought one a while ago now, it would have saved all sorts of grief.

    Ordinairly, I would not bother with posting about something so mundane as a simple alarm clock, but at the risk of sounding like a commercial - I really like this one.

    US$20 https://www.amazon.com/Electronic-Settings-Humidity-Temperature-Electric/dp/B07RKTVQDR/ref=sr_1_1?dchild=1&keywords=Digital+Alarm+Clock%2C+with+Wooden+Electronic+LED+Time+Display%2C&qid=1617931534&sr=8-1 (https://www.amazon.com/Electronic-Settings-Humidity-Temperature-Electric/dp/B07RKTVQDR/ref=sr_1_1?dchild=1&keywords=Digital+Alarm+Clock%2C+with+Wooden+Electronic+LED+Time+Display%2C&qid=1617931534&sr=8-1)

    The design actually makes sense! I set it without looking at the directions (that was the first test). After reading the directions, and investigating it further, it has a minimum of incredibly stupid and awkward functions that I would never use. They put a wheel to set options like time and brightness (which is intelligently scaled). It has a cr2032 for power loss time keeping (not sure how long). It does NOT blink the colon - who the &^%# decided clocks should blink colons - would we forget they are on if they were not blinking?? ANY button will snooze for 9 min - the last thing I want is to wake up and start fumbling for the right snooze. Temp/RH is a nice touch and date can be switched for temp. Other stuff, but overall, a good design and I am impressed.

    On UT61E, hold the REL key when turning on to disable auto power-off. For me, the automatic power-off that can be enabled/disabled is a good feature.

    Cyclonic Dust Extractor
    The black cyclonic adaptor arrived last Friday from China.
    3D printed parts are the hose adaptors for the Karcher vac, exhaust air deflector and the suction relief valve on the very top.
    Without the suction relief valve I was at risk of collapsing the rubbish bin.
    Finished and tested this morning. Works a treat.
    The electrical tape is a temporary solution. Now that I am happy with it I will epoxy those joints properly.
    Now I won’t need to replace the vac bags nearly as often, saving a fortune on those consumables.

    Aggressively non-ovened crystal oscillator. This one's more of a naked sunbathing fan.

    Apparently made around 1958. Still oscillates pretty close to 10kHz.
    I'll do my best to remove that solder from the pins but the silver plating will be mostly gone.

    I'd like to find a connector (see pic) to match  - 8 pins, 2.4mm diameter pins, 6.5mm major spacing.

    They work great on a smaller shop vac  :-+ For the Drum I made a new routed top from 3/4Ply as part of the cart build. Vac around the other side.

    Today I ordered Bandsaw blades just to keep it a little off topic  :-DD

    I've bought a Teraohm meter with a rather high test voltage of 500 V.

    Quite a specialized piece of kit, but i need it to test my homemade SMU Triax cables: cables from Keithley have a resistance of 10^15 \$\Omega\$ between the two inner conductors, and that has to be measured at 500 V.

    My test cable reached something like 5x10^13 \$\Omega\$, so it's only 20 times worse than the cables from the manufacturer (but i didn't have to pay 400 bucks per cable). I don't think that i'll reach the manufacturer specs with my cables, turns out that black heat shrink tubing is way more conductive than i'd like it to be for this job.

    I picked up something that I have wanted for a very long time but I am cheap and wanted a deal.  Found a Powr Kraft sold by Monkey Ward floor standing drill press quite cheap, at least to me, 100 yankee bux.  The guy I bought it from is older than me and it was his father's who was a machinist.  Needs a good cleanup and I have to get rid of some surface rust.  Guy believes it's from the 50's, like me and it has its quirks, like me!  The return spring is broke but they are cheap.  Also, most of the time, you have to spin the chuck by hand after turning it on to get it moving but it is quiet and smooth when up to speed.  He also said that his dad added pulleys to make it a 3 speed press.  Not sure if it is true, haven't tried to get model number off the plaque and do some research.  I can tug on the chuck at full extension and there is no movement.  As an occasional use item, it will live a good life in the garage and it will even be covered when not in use.

    You certainly make yourself happy! :-)
    Copying my soon "former" job toolset.
    better DMM, Scope, generator, soldering station, hot air station, table drill, micro drill (I have more tools already), screws&nuts M2-M12, components PTH and SMT, shrink tubes and tapes, some basic boards, arduino and such. Let´s say $3000 starter kit. :-)
    Hopefully I will do more work on myself rather than in not-very-thankful-job. Good days coming hopefully.

    better DMM, Scope, generator, soldering station, hot air station, table drill, micro drill (I have more tools already), screws&nuts M2-M12, components PTH and SMT, shrink tubes and tapes, some basic boards, arduino and such. Let´s say $3000 starter kit. :-)
    Hopefully I will do more work on myself rather than in not-very-thankful-job. Good days coming hopefully.
    Any ideas and tips on what else would "young" electronics guy need?

    Have you seen Dave's video on how to kit out an electronics lab?

    My friend's story about getting nicked by a mower blade (a thumb full of stitches), started me thinking about how much I use a Dremel saw blade and decided that one of these might be a good idea :)

    That is interesting; I lost count of how many cutting discs shattered while using the Dremel. That is why I always use large protective glasses with this tool and occasionally thick gloves.

    I used to have that problem with the pure abrasive ones, too - I'd get most of the way through whatever I was cutting, then twist slightly by accident and the wheel would vaporize.  As would the following three, almost immediately.  Then about ten years back I was looking around at the store and discovered that they'd come put with fiber reinforced ones with a quick-lock mandrel.  More $$, but they completely eliminated my 'grenading cut off wheel' issues, so I've been buying those ever since and never looked back.  Given that I can consistently use them until they've worn to bloody nubs, they're probably overall cheaper because they don't shatter if you so much as twitch, meaning you won't go through half a package if not properly caffeinated while making a cut.

    I recently bought 2 brand spanking new (well, NOS out of the '50's but in pristine condition) Philips E1T's, which are a funny combination of a dekatron with a CRT. I'm so excited!
    On the bottom is printed: WK1 M58. Does that mean it's produced in week 1 of 1958 or what?

    Beautiful valves!
    A quick search reveals the M58 may refer to December 1958 (A = Jan, B = Feb and so on). The WK1 may be related to the country of origin.

    A new DER DE-5000 LCR meter with the tweezers, alligator clips, and ground cable accessories. I've been sniffing around these for a while. Got a good deal on it, so I pulled the trigger.

    An uninvited guest! I ordered an Alienware T-shirt from Dell before. After waiting for a long time, their customer service emailed me that the L size was out of stock and asked if I could accept the XL size. So I chose to cancel the order and they quickly refunded me. The story should have ended here, but I got an XL size Alienware T-shirt delivered this afternoon, what should I do now?   :-//

    There it is something that I've been missing and post-noting to buy one. It will be this year definitely.

    Well from me I've been buying some stuff since last update:
    (https://i.redd.it/buqkh09ruws61.jpg)

    Some games for the Nintendo Switch (Xenoblade 2 - Torna, Sonic Mania Plus and Fire Emblem 3H), a pair of clip on headphones (Audio Technica ATH-EM7x) that are surprisingly good for gaming on the go and the new member of the family - A GBA that I got for 120RMB all scuffed up and battered and with more dust and dirt than I was expecting to see inside. Spent 120RMB more and bought a replacement shell, new buttons and membranes plus a Glass Lens since the original is plastic and looked like sandpaper.

    Thrown everything in the trash except the Mainboard, LCD and Speaker. Spent an afternoon cleaning everything with Isopropyl Alcohol, and reassembling everything. What it misses now is some reproduction stickers on the back with the original SN (I kept it before throwing the old shell away).

    8000 pcs of TDK MLP1005M1R0DT0S1 for $100 from a HQB liquidator. 2014 vintage NOS with original TDK and Digikey labels still on.

    I figure that 0402 industors suitable for MHz SMPS applications are rare, and it just happens I prefer to save every possible square mm on my board, so I bought a few to try it out. It turns out that this thing works happily with EA3036, a super cheap 3mm*3mm 3ch buck converter IC.

    Realistically I do not expect this thing to deliver anything more than 400mA, but for IO voltage or core voltage of a tiny FPGA, this is more than enough, at a small size (with EA3036 and this 0402 inductor and 0402 caps and 0201 resistors, at 3 ch this can beat many SiP modules).

    Isn't 400mA really pushing it? ~80mW dissipation. An 0402 resistor is something like 50-60mW.
    But yeah first time I used a 0603 bead for a PSU I thought it just won't work.. its not a "proper" wound inductor.
    EA3036 looks really good for 10c.

    Finally I got a label printer that I can connect to my computer. I didn't find a driver and a program that would work for me on Linux, so I hacked a solution from another solution. Took a while to make it working, it's not perfect, but good-enough.

    Very nice one ! I was asking myself what that huge power supply on the right was for, I got the answer :

    Quote
    A 150W halogen illuminator with 35" heavy-duty fiber-optic ring-light provides the smoothest overhead lighting possible. Active cooling and auto-shutoff avoids overheating in strenuous environments.
    Wow.

    Perhaps I'm the exception, but I gave up with ring illuminators on microscopes as I found they get in the way of tools, in particular the hot air gun. Instead I use a pair of 3W LED narrow spots on goosenecks mounted opposite each other clamped to the microscope.

    I have been doing something similar too for the last year or so but I am going to have a go at a softer diffused light and see if I prefer it. The spots throw harsh glare on the shiny bits even when done from the sides. I do have plenty of room under the camera on my setup so it shouldn't get in the way to much.

    May I ask you, if you can measure the maximum eye distance (mid-mid) of the okulars?

    I had ordered a trinokular only to find the eye distance some millimeters too short for my obviously XXXL head and sold it again.
    I now settled with the zoom camera, Dave made a video about. But that's no stereoscopic view of course.

    McBryce.

    Exactly. I despise the shielded plugs. I almost never connect to anything at a high voltage and if I do, it's just probing with a handheld DVM - not something likely to leave uninsulated plugs lying around. Yet all my probes have them.

    One of the most stupid is the Fluke 80 AK accessory that converts a thermocouple to fit a DVM. If it ever has more than a couple of mV on it, then it was connected to that with an abused and completely unshrouded thermocouple plug.

    US $25 (a few hours left on the sale)...couldn't resist...well, I could, but I really like toys :)

    https://www.bhphotovideo.com/c/product/1626703-REG/sunpak_sp_4k_ac_kit_4k_action_9_piece_camera.html (https://www.bhphotovideo.com/c/product/1626703-REG/sunpak_sp_4k_ac_kit_4k_action_9_piece_camera.html)

    So, to provide some real-world impressions now that I have had it for a while....

    BLUF: At the price I paid, it is a nice.

    On the price: Yes it was a special sale and the price has gone back up. But (and I knew this before ordering) Bungood sells a similar/identical unit https://www.banggood.com/SJ9000-Wifi-4K-2Inch-1080P-Ultra-HD-Waterproof-Sport-Camera-Action-DVR-Camcorder-p-1776031.html?rmmds=detail-left-hotproducts&cur_warehouse=CN (https://www.banggood.com/SJ9000-Wifi-4K-2Inch-1080P-Ultra-HD-Waterproof-Sport-Camera-Action-DVR-Camcorder-p-1776031.html?rmmds=detail-left-hotproducts&cur_warehouse=CN) at about the special sales price. BUT, B&H Photo is a legit place that I have ordered from several times over the last decade or so...never had any trouble and free shipping and it got here pretty quick.

    The movie quality is, in fact, pretty impressive, at least at the highest resolution. Granted, I am much more experienced at still photography (which it also does), but still, I was impressed. Not a whole lot of controls though (some exposure control).

    Sadly, there is no USB control at all: only power is being used over the USB port...that is a disappointment. There is an Android App available so you can log into the camera remotely and activate many functions. It works, but only barely.

    From my searching around, it is not hackable in a friendly way....

    So, that is basically it...I probably will get some use out of it as it is small and handy.

    Perhaps I'm the exception, but I gave up with ring illuminators on microscopes as I found they get in the way of tools, in particular the hot air gun. Instead I use a pair of 3W LED narrow spots on goosenecks mounted opposite each other clamped to the microscope.

    Finally got a microscope big enough to work under. I did a few leads of a QFP64 and giggled a little.
    (Attachment Link)

    May I ask you, if you can measure the maximum eye distance (mid-mid) of the okulars?

    I had ordered a trinokular only to find the eye distance some millimeters too short for my obviously XXXL head and sold it again.
    I now settled with the zoom camera, Dave made a video about. But that's no stereoscopic view of course.

    Looks like 3" and they are linked so one moves the other.

    Thx for that! 3" would be 7.62 mm.
    So I'm somewhat reassured that buying a camera solution might have been the right decision.

    Geiger tube

    Update : apparently this tube is made for testing liquids. The bell mouth visible in the picture is the open end of a test tube, and the glass enclosure of the GM tube itself is inside and coaxial with it. So, liquid poured into the test tube surrounds the GM tube in a layer about 1mm thick.

    Hello,

    It has been a while since I shared my scores here are the new ones since my last post.

    First a nice HP 4328A, sold as parts, but, once switch contact cleaned, was fully working and measurements are close to my UT612. I don't have proper capacitors nor inductors to check it for calibration.
    It was delivered with half-a-probe, the half with the RM12 front panel connector, as the other part of the probe is unobtainium, I did cut it near the end, and made a quick 5 alligators "kelvin" probe with it. This small probe will be usefull in low ranges as the length of cable is limited.
    RS Components in Europe still have the RM12BPE-5PH connector at 16€.

    Next a HP 6114A precision power supply, it had some trouble with a buzzing Sprague capacitor across the output of the transformer, broken binding posts, needed cleaning of the volts/amp switch, and of the voltage selection wheels. It is quite pleasant to use.

    To complete the 4328A I found a HP 4332A, again cleaning switches makes it back alive and in agreement with the other TE on hand. Last cal in 2012.

    While waiting for the postman I finished the repair of a HP 410B VTVM. It needed love : dead filter caps, seized pots, open 6-4 filament regulator tube, and of course leads were damaged. Once all corrected it works nice, but i really dislike the attached leads.

    Lastly a little Heathkit SG-8 R.F Signal Generator. It was so cheap I couldn't resist. Previous owner took care of the filer caps. I took care of the two other ones in the AF section, and cleaned the tuning capacitor as it was sparking a lot. I did the modifications suggested by this post : https://canadianvintageradio.com/cvrs-forums/topic/heathkit-sg-8-article-in-newsletter/ (https://canadianvintageradio.com/cvrs-forums/topic/heathkit-sg-8-article-in-newsletter/).
    The knight 600 confirmed that the 12AU7 oscillator tube is weak : it doesn't oscillate on the E band below 60Mhz. "New" one ordered.

    And, a Chinese ultrasonic cleaner...

    Thomas

    I bought several 365nm UVA LED flashlights for detecting counterfeit money (one for myself, and a few to bring to the store I work at to give to my coworkers there, a store which unfortunately got successfully scammed recently by somebody paying with very realistic looking fake $100 bills). I bought a 940nm NIR LED flashlight as an illuminator for my full-spectrum modified webcam. I bought some UVC fluorescent cards that theoretically glow green only when exposed to UVC light, but not UVB or UVA. I hope to use these in place of a $3000+ spectrometer (as mentioned in this thread https://www.eevblog.com/forum/testgear/any-good-uvvisible-usb-connected-spectrometers-at-a-reasonable-price/ (https://www.eevblog.com/forum/testgear/any-good-uvvisible-usb-connected-spectrometers-at-a-reasonable-price/) until I can find a cheaper spectrometer) for verifying the UVC output of UVC LED disinfectant bulbs I plan to buy at some point from eBay.

    Buy and Hobby Knife plus extra blades and for 140RMB more get a Pentel Orenz Nero.

    Also got a Fluke case for my 87V, the same one as it comes with the Fluke 376 FC clamp meter. A little bigger (not a lot) but for the price since it was from someone who had a tool backpack and didn't need the included one, I can't say it was a bad deal for 80RMB.

    But i chose to get the CZ version , as DK-Mail always cathes those packages from CN , and add 25%VAT + 25$ Customs fee.

    Definitely I will use this one for the 289 instead and the one that come with my 289 FVF kit for the 87V.

    This one is perfect for the 289 size plus the side could hold the roll up pouch of the Fluke TLK-225 SureGrip Master Accessory Set easily.

    The stack is growing!   Newest edition addition is the 34401a.  And youngest of the bunch!

    Dangling is an ADR4530 3.000V voltage reference; ±0.02% (600µV) tolerance.
    Before the 34401a made its appearance, I'd made it to validate whether the 3478a was in the ball park.
    The 34401a has a valid calibration sticker so I'm pretty happy considering they're 33 and 28 years old.

    That's not their doing - if they charge something they have to add VAT to it.

    In Portugal is the same. If  DHL, TNT or UPS do receive a parcel for you that needs to clear customs, they will send you a bill with how much you have to pay regarding customs plus a 60€ of "Handling Fee" that is basically their tax for the documents needed to clear customs plus their work.

    Even if you say that you don't want to pay that tax and don't want them to do anything, you can do the clearing of customs by yourself they don't allow it, saying that they have "special treatment" with the customs office and that doesn't allow end customers to do such job.

    Because of that if possible all parcels that I received after that was always going via EMS, slower but it's me who takes care of the documentation.

    By the way the documentation is 10€ for the customs office if you pay or not. If it stops and you have to show proof of an invoice or the price you bought the item, you are already paying 10€ just for they printing a sheet of paper saying you don't need to pay. I don't know if now is different since the Postal Service in Portugal changed hands from the Government to a Private, with an IPO some years ago but I know that now a lot more parcels stop than before. But a LOT MORE!

    In Oz we as individuals can do our own Customs Clearances so for small ones under $10k I used to fill out my own ('Nature 10' in Oz) https://www.abf.gov.au/imports/Pages/How-to-import/Import-declarations.aspx (https://www.abf.gov.au/imports/Pages/How-to-import/Import-declarations.aspx) With larger shipments or partial container lots a Broker is generally $ well spent.

    Worth having a look at your own Governments to see if there is a similar system. When you have done a few they are easy.

    I do my own custom clearances. Always done when I needed. My peeve is not not knowing how to, is DHL/TNT/UPS doing it without first inquiring if the customer wants or not.

    Most probably would not care and pay gladly to have someone do their work. But I don't specially when I can do it for less than half they charge me.

    In the Postnord case it probably stems from the fact that mainland China, in the fees and tariffs scheme of the UPU, is a third world nation, and as such is exempt from paying a lot of the transfer costs for international mail. Sweden and Denmark, OTOH, are in the highest charging level, and then have to carry all the costs of that operation. Postnord basically get a shitload of $1 parcels with fake IC's, banana jacks, sunglasses and dildos dumped on them, and are expected, according to UPU rules, to deliver them for next to nothing.

    Shipments that have declared value under ~ 75€ are exempt from customs fees, but not VAT free. And, the rules allow the import handler to charge a fee. The VAT goes to the tax authority, the handling fee to the shipper.  And no, they can refuse you the right to handle customs processing.

    The loophole of course is the "Czech warehouse" which is a paper-thin store front to the same Shenzen merchant, but inside EU. Only one VAT process, and no customs. Most importantly, no handling fee.

    I also got a Hot snot gun  :-+

    I have the same snotgun - it's good.

    I'd also recommend their small rechargeable snotgun. It warms up much faster than mains-powered guns, tells you that it's hot, turns itself off automatically and lasts a surprisingly long time on a charge. My only complaint is that the gluesticks tend to fall out until they're feeding the tip, and the squeeze mechanism works on the backend of the stick. So there's a relatively short period when the stick is both held firmly and pushed by the trigger.

    That's something I will worry about when I'm back in Portugal for some reason. Currently if I need something, or comes directly from China and it's 2 days of shipping or if it is international I ship it directly to Hong Kong and then a family member will keep it until I'm able to collect it, since HK is a free port.

    FETs may have replaced valves as electrometer inputs but I can't see them getting the degree of isolation that long glass neck is designed for.

    Well spotted. Yes, it's the buttons. Specifically, that the buckling-spring switch bodies have NOT been heat-staked to the PCB. They are held in place only by the front metal plate. All three units I've bought are like that, so it was apparently manufacturing standard for the 3437A.

    I don't know of any other HP instrument with those switches still having their mounting stakes intact. Which means the HP3437A is the only source of replacement switches that I know of.

    Are there any other HP instruments using the same button-switch mounting scheme?
    It would be good to find something that:
    * Has a lot of buttons,
    * Is fairly cheap and common on ebay,
    * Is relatively light so shipping doesn't cost a fortune.
    * Is really obsolete and useless, so stripping it isn't painful. The 3437A is quite a nice instrument.

    Ideally I wish I'd find a box full of just those front panels, for cheap. Like that's going to happen.

    Not exactly bought, more a pre-emptive dumpster dive. As in: prevented this Meinberg LANtime M300 from ending in the recycling stack.  This unit takes time reference information from the VLF transmitter (77kHz) DCF77 run by the Physikalisch Technische Bundesanstalt (~= NBS for you in the US) in Germany.
    It serves as an NTP server but also produces a 10MHz and a PPS signal. DCF77 is of course driven by multiple atomic clocks. Signal is receivable about 1500km from the transmitter site (IIRC).

    I'm 1200 km from the Langwellensender, and even with very cheap clocks we can receive the signal. I've got the same mainframe but with a GPS receiver in. Having a 10MHz signal on-tap is a force multiplier for every lab. Exact time is also good.

    About 10 years ago I designed a dual Meinberg M300 NTP solution for a major Dutch bank for use in a dual data center config. In that case I used dual receiver M300's so GPS and PZF. We wanted to be really sure we always had reliable time on our hands 😀

    To the best of my knowledge it is still operational 👍🏻

    As for 10MHz ref: fully agree! Although 2x GPSDO, 1x Rb reference plus the DCF77 Meinberg might be somewhat overdone.  Frequency nut in the making? 🤔

    Note that depending on the voltages you plan to use the viewport could let a lot of soft x-rays out.
    I use an x-ray blocking glass on top of my viewport unless it is used with a camera with
    a shield between it and the operator.

    Hope you will post the results on eevblog too!

    Cheers and have fun.

    A small CCD camera and a mounting flange is definitely on the watchlist! A piece of leaded acrylic would also be neat.

    In the first iteration, an UV light source is mounted on the viewport to provide a steady flux of photoelectrons as MS ion source. I'll for sure make a thread about it when I get a bit further. :)

    Micsig DP10013 high voltage differential probe. I can now fulfill my noob dreams: looking at the mains on my scope.

    Really, I want to look at the power section in a vacuum tube guitar amplifier that starts off as 120VAC and is transformed to 200VAC. I want to see the rectification and the smoothing and what happens if I swap out this for that. Now I can. This makes me happy.

    Here's the mains at my lab bench:

    EDIT:

    (replying to Cubdriver in an edit so as not to take the thread too far off course) Yes, it's ugly. It's my understanding that this is pretty normal. I imagine that this knowledge would really infuriate the audiophools with expensive pure silver IEC cables.

    Well, not exactly "buy" but a guy at work noticed a 3D printer in the trash at the university dorms, and thought I might want parts from it.  I tried it out and couldn't see anything wrong.  I tried a test print that tried to work, but it was loaded with ABS but the print was set for PLA.  So, today I downloaded cura, saw it didn't have a post for this printer (Stanley Model 1) and found a download for the config for the printer.  Then I downloaded a random object from Thingiverse and it worked remarkably well!

    So far, total cost about 3 hours of my time.

    My Panavise Jr's thumb screw somehow got out of alignment and I am going to have to disssemble it or something.


    It definitely could use a bigger knob. Luckily I have several other work holders. I mostly use my panavise jr for holding small antennas these days.

    I love my pneumatic impact driver but once you buy a battery-powered rattle-gun you will never look back.

    Speaking of automotive tools...

    Based off of the recommendation below, and my own good experiences with Astro Pneumatic tools for automotive repair, I bought the Astro Pneumatic Tool 9477 7-Piece Professional Quick Interchangeable Ratchet Crimping Tool Set. It was about USD70 delivered. I would say that it works pretty well (meaning the crimps are not mangled to hell) for hobby use. I like that it includes a bunch of dies for (relatively) cheap, and the dies are indeed very easy to swap out.

    Quote from: jwm_ on February 17, 2016, 08:54:19 pm
    I use the astro one and a real crimper is one of the best purchases I have made.

    http://www.amazon.com/Astro-9477-Professional-Interchangeable-Tool/dp/B0045CUMLQ (http://www.amazon.com/Astro-9477-Professional-Interchangeable-Tool/dp/B0045CUMLQ)

    the dies are simple to change, just pull it out and push another in and the case is rugged and holds things in.

    The only thing i'd like is a cheat sheet on the case that shows which terminal types go with which dies... perhaps i can make one up..

    The picture is of the one that I own.

    EDIT:

    The ABN Quick-Change Ratchet Crimper Pliers & Die 6-Piece Crimping Tool Kit – Insulated, D-Sub, Barrel, & More Crimp Set appears (from pictures) to be identical, but it's only USD47 vs USD64 for the Astro Pneumatic version.

    Liquid Electrical Tape  :o but not for that purpose. For reasons unbknown in Oz we seem not to be able to get Liquid Tool Dips like Plastidip, Loctite etc. (we can get spray cans of Plastidip but the price is nuts). So I am going to give this a go, ordered Black and Clear and I have some powdered dies for a bit of a play with colour on the clear.

    Anyone used it for this purpose or got any Oz available liquids?

    No, got a bottle to use to repair rubber equipment cords that are not replaceable, and where the rubber was slightly scuffed from wear. Buying a new $5k motor because you need a new cable is not exactly easy, but the manufacturer pots the entire winding assembly in hard resin during manufacture. Kind of have to with a 2HP vibrator, but having to buy the whole motor is hard. So just used to repair the scuffs, and then also used a bit more for doing cable joints on electric fences, as this makes a good insulation that lasts. the biggest user is the boating industry, where pretty much every yacht owner will have a can or three around to make connections water tight in the engine bay, so they can have it last more than 3 months in the ocean.

    Yep Marine wiring sucks. I used to have a share in a Boat and I was the designated fixer, generally after one of the others had played :palm: The boot liner stuff looks good for other purposes maybe too.

    Todays random arrival is for powering my TS100 as an option. Generally I use my R/C packs and a DC-DC convertor but there is times I will have the Makita gear and no R/C packs on site. Evilbayplus got me some more $ off it but decent plastic and a firm snap lock  :-+ eBay auction: #303975839184 Wire is a bit stiff so I will likely swap it out. Adapter also works on some Bosch packs too.

    Some tools.

    A Sydney hardware store chain, humorously called 'Total Tools' had a sale on recently. I went intending to get just an air compressor. One of a sensible, movable size, not my tiny one that was originally for airbrushing but is all that fits in my small cramped workshop, or the gi-normous 3-phase one I still don't have set up in my larger but unfinished workshop.

    Turned out the store had a points deal - buy $2K of stuff, get a significant bonus to buy more stuff. So I added a Makita kit with a cordless drill and impact hammer. My old cordless drill was a freebe, worked great for years but used NiCad battery packs that are now dead.

    With the bonus I bought some vices, clamps, big spanners, tap and die set, wire brushes...

    They put on free pizzas and pretty girls too. I left, the compressor in wooden frame only just fitting into the car. Feeling pretty pleased with the day. Had picked up a catalog on the way out the door.

    In the next few days, using the cordless drill I really like it. Nicely responsive, finely controlable speed. One warning - the torque limit adjusting ring only operates in 'screwdriver mode'. In the drilling and hammer modes there is no torque limiting. That's not really clear in the manual, and it SHOULD be because... this thing has monsterous torque. One of the first things I did was a (stupid) quick power test - fixed the short bar of a large allen key in the chuck, grabbed the long end of the allen key firmly, and gently pressed the trigger.

    Oops. Even at low power it completely ignored my grip, ripping the bar out of my hand. Luckily, no injury though it hurt. So... don't try that. Also note to self - in drilling mode with large drill bits if the drill bit jams, this thing is going to rip the drill handle out of your grasp. I like it!

    But there was one final nice surprise.
    I happened to look through that catalog. Discovered that Makita has a 'redemption' deal going on several items, one being that kit I'd bought. You get a free thing... depending on what you bought. For that kit the 'thing' is a battery powered angle grinder. A GOOD one! This was totally unexpected. I'd already got some free stuff from adding that kit to my buy at the store, now more free stuff? And it's something I'd always wanted, whee!

    I filled in the online form, emailed with a scan of the store invoice, not quite believing this would work. I hadn't even known what the word 'redemption' meant in this context till it was explained to me. Never was involved in such a deal before.

    A few days later the angle grinder arrived. No battery pack, but the kit had included two. I haven't yet flattened a battery, but I'm told it will operate the grinder for quite a while. An hour? It's hard to believe. We'll see.

    The grinder is *great*. Very much a Bwahhaha feeling, to have a no-cord portable grinder. It's a bit quieter than typical mains powered grinders too. As if that might be important for some reason...

    Makita makes really good stuff - teal has been my color of choice for cordless tools for almost 25 years now since getting my first GOOD cordless drill from them in 1998 after using an earlier one at work regularly.  Recently added one of their 18V angle grinders and a metal cutting circular saw to my arsenal thanks to some sales that were going on here a few weeks ago.  And finally, about a month ago, I broke out the 18V drywall saw I'd bought a year ago for a project that then got put on hold.  That thing is fantastic - connected to a shop vac it makes drywall surgery nearly dust free and cuts a treat!  Wish I'd had it years ago.

    Congrats on your new 'toys'.   ;)

    Along with a small easy to carry creeper, and a set of goggles and a mask, plus a very dark bag that will hold the grinder, the creeper and also a few somewhat large stainless steel thin wall cylinders, with a somewhat contaminated ceramic honeycomb matrix, inside them, in separate pouches so they do not make a noise when you are moving with them.

    Nice selections on your part.  :-+

    A word of warning for Li battery packs.
    Never put away fully discharged packs without putting some charge back into them.
    The BMS systems are sometimes powered by a single cell and can drain that cell to levels where the smart charger will reject the pack as faulty and when it's offered to the charger 3 times in the same condition will reject it permanently.
    They can be brought back by externally dumb charging so the low cell comes up to a level the smart charger accepts however this must be done before the charger has rejected it 3 times previously.

    Early Makita Li tools suffered from this badly but they may have addressed this due to all the bad publicity they had about it a few years back. Our son in Perth lost 3 of 6 packs in this manner and now only has Milwaukee equipment.

    I've been mostly happy with the Makita battery grinder. I don't miss the cord. Tho, in recent times found that the ball bearings soon wear out if you cut a lot of dusty things. Got the parts kit for one of them and all that did was transfer the seizure further down into the frame.

    Watch out for Makita as they are sometimes now slipping in plastic parts where metal parts should be. And on hard to recognise model variants. If you cut a fair bit of concrete, be ready to turf it when it munts.

    Love the cordless grinder for a quick job too but for serious work I still run the lead out for the 240V one.

One of a sensible, movable size, not my tiny one that was originally for airbrushing but is all that fits in my small cramped workshop, or the gi-normous 3-phase one I still don't have set up in my larger but unfinished workshop.

    snip

    The grinder is *great*. Very much a Bwahhaha feeling, to have a no-cord portable grinder. It's a bit quieter than typical mains powered grinders too. As if that might be important for some reason...

    Dangerous place we had a franchise Store open locally a last year and they have got some pesos from me already. Last week was a set of Makita Stacker boxes to get all my power tools arranged from their multiple places. Opted to DIY wheeled platform as $100+ for a dolly is OTT.

    Love the cordless grinder for a quick job too but for serious work I still run the lead out for the 240V one.

    I've also got the 9'' (two battery). It's not too bad compared to the regular 10A 240v grinder. Got it from a guy who bought a whole kit from a dealer (like above), he didn't need the big grinder, 150 bucks off brand new.

    I've been mostly happy with the Makita battery grinder. I don't miss the cord. Tho, in recent times found that the ball bearings soon wear out if you cut a lot of dusty things. Got the parts kit for one of them and all that did was transfer the seizure further down into the frame.

    Watch out for Makita as they are sometimes now slipping in plastic parts where metal parts should be. And on hard to recognise model variants. If you cut a fair bit of concrete, be ready to turf it when it munts.
    Yep plastic gearcases are becoming increasingly common in all brands and should be avoided at all costs for any serious tool.  :horse:

    So you've never pushed a full barrow load of wet concrete up a steep incline ?
    Or even aggregate for that matter.

    Up some inline on planks over an excavation is where I see powered wheelbarrows would be extremely useful.
    Wonder if they have regen braking when going downhill.  :-//

    And it can be difficult or even impossible to push a heavy wheelbarrow through soft mud, as the wheel wants to bury itself. Note the aggressive tread of the Makita.

    Cable-actuated front wheel disc brake, by the way. There is also electric braking but I doubt it would be regenerative.

    As someone who has helped a Concreting mate of mine on plenty of occasions  :-+ for a powered wheelbarrow. More than one of those jobs has been barrowed (unpowered) from the truck to the job as they were to small or not worth bringing in a pump. Not so bad if you are on hard ground but throw in an incline or a ramp/step and its not a good time.

    Now I am 'to old' my helping days are over powered or unpowered  ;D

    A pH pen that (hopefully) does not suck. My previous pen perhaps did not suck initially, but storing it badly has led me to doubt it.

    Milwaukee Instruments also sell separate electrodes with BNC plugs. Got me thinking about doing something permanently rigged for measuring pH of the pool, and of course plotting it.

    The Lens adapter arrived last week and the Camera the week before but the pair of MF Risers arrived today so I got to actually use it and the camera in focus with the eyepieces https://www.aliexpress.com/item/32843818172.html?spm=a2g0s.9042311.0.0.236e4c4dSFoOYF (https://www.aliexpress.com/item/32843818172.html?spm=a2g0s.9042311.0.0.236e4c4dSFoOYF)

    Apart from really needing a third one as the Lens is more or less pegged to one end of it's adjustment range they do the job (still a little fuzzy at the peg when the Eyes are in focus). Not that I am likely to go back to soldering with a camera the 1/2 adapter gives a Camera width of about 30mm to the eyepieces 50mm so today I added a 1/3 lens and another pair of MF Risers.

    Makita obviously knows their market.  Next thing you know they will include a spark suppressor.  Strictly for safety of course.

    Quite recently, a very large bush (forest) fire in Western Australia was caused by someone cutting metal with an angle grinder, so sparks can be a safety hazard.

    Of course sparks are a safety hazard.  I have started fires myself with angle grinder sparks.  Care should be used to avoid this, and you should keep a fire extinguisher handy in case your care isn't enough.

    Perhaps some have missed the veiled reference to what is at least a portion of the market for a quiet cordless angle grinder, those who are using them to grind off locks, chains and other de-portability devices.  Who don't want audible or visible evidence of their nefarious operations.

    In pursuit of collecting the most archaic 'digital oscilloscopes' possible, this arrived today.
    A HP  5180A 'waveform recorder.'  (HP 1983 cat, pg 171)
    20MHz sample rate, 16K sample memory. Requires an external XYZ display. (Which I have.)

    It powers up but displays an error on startup. The manuals are still in the post, so no teardown and repair attempt for a while yet. Just a cover off, LEDs-test pic.

    The CPU is an MC68A00P, and code is in three mask-ROMS.

    One brief moment of horror - there's an empty card slot, A6, marked 'DAC' on the motherboard.  But the card-retaining foam rubber strips show no sign of that card ever being present in the past so I'm guessing it's some optional feature.

    There's one small plastic button cap missing. See https://www.eevblog.com/forum/buysellwanted/wtb-some-old-hp-equipment-plastic-buttons/ (https://www.eevblog.com/forum/buysellwanted/wtb-some-old-hp-equipment-plastic-buttons/)

    Since you already have some of the missing button caps, may I recommend you measure them carefully (using proper calipers) and provide the measurements, so that if you or others cannot find any, they can be at least 3D printed in PLA or ABS?  And, if someone isn't sure but has an assortment of old buttons, they can check the measurements to verify?
    Title: Re: What did you buy today? Post your latest purchase!
    Post by: TerraHertz on June 16, 2021, 11:18:09 am
    I'd have done that, if I thought there was any point. But there are multiple reasons why there isn't:

    * These are quite common. Anyone having any old HP gear, needing more, AND having a 3d printer, will have some of these already. They can measure them themselves. So the remaining tedious details are superfluous reasons why I didn't.

    * The outside is 2-slope pyramidal, with radius on each transition. So much fun to try and measure precisely, calipers or not.

    * The internal shape and its dimensions are complex, and 'press-fit critical'. Good luck trying to measure and print it to good enough tolerance to actually work.

    * The click-fit and resistance to popping off again, is due to 2 tiny little ridges on the inner faces, that key into grooves on the switch shaft. Molded in some very hard plastic. Good luck getting them right in 3D printed thermoplastic and not having them just flatten or shear off when pressing the button on.

    * The color and surface texture matching is critical for old gear historical restoration. I do not believe that 3D printing using commercially available filament could possibly get even close. And so there is no point whatsoever. Better to have no button than some bodgy crap-looking immitation.

    Thanks for the suggestion, but I think it was a knee-jerk 'off course 3D printing solves everything.'
    Rear feet and some other parts where color and texture don't matter, sure. I did see the thread on making parts for restorations when searching for sources. But not suitable for these.

    No, not really; it's just that without measurements, one cannot really tell if they have these or not, unless they know they are for HP equipment.

    3D printing replacements would be a temporary solution anyway.  I'm not a 3D printing fanatic..

    For similar reasons you outlined above, for completely new buttons, one would need to make aluminium molds for casting in ABS.  Or rather, a mold with an inner "piston" with the inside features, that one could press semi-molten ABS into shape against the smooth mold in the outside shape of the button cap.  Add a couple of ceramic heating elements and a thermocouple or an RTD to the aluminium mold, so it can be kept at 105°C - 150°C (above the glass transition for ABS).

    I thought this might come in handy if ever one runs out of available replacements, or wants slightly customized replacements.
    Hopefully someone keeps at least one cap in pristine condition, so that measurements can be made, before that happens.

    :) It seems you are not a collector of old HP test gear. Everyone who _is_, knows these buttons well and very likely has some gear with them. Everyone who _isn't_, won't have any of them, or care.

    I can't imagine why you felt it necessary to explain to me how injection molding works.
    No one is ever going to bother making new molds for these or any other old instrument buttons. Even the Chinese wouln't, due to the tiny market size. There is never going to be any source other than scavenged from wrecked pieces of equipment. Same with the HP 'buckling spring' switch bodies.

    I can't imagine why you felt it necessary to explain to me how injection molding works.
    I wasn't thinking about the industrial process, but the hobby one: doing it in singles at home, not commercially.  I bet you are thinking of the commercial injection molding process; I'm not.

    I admit, I was distracted trying to think of a way to create the details on the piston using hobby equipment when writing that.. Sorry.  The piston part is the hard one, probably would have to be made in parts.  My local Hacklab does have a CNC machine so neither precision or price should be an issue.  I already have suitable ceramic heating elements, RTDs, and microcontrollers that can interface to those, so its definitely feasible in theory – whether the results would be worth it, I have no idea.
    Casting or injection molding custom button caps might be a fun hobby project.

    I'd have done that, if I thought there was any point. But there are multiple reasons why there isn't:

    * These are quite common. Anyone having any old HP gear, needing more, AND having a 3d printer, will have some of these already. They can measure them themselves. So the remaining tedious details are superfluous reasons why I didn't.

    * The outside is 2-slope pyramidal, with radius on each transition. So much fun to try and measure precisely, calipers or not.

    * The internal shape and its dimensions are complex, and 'press-fit critical'. Good luck trying to measure and print it to good enough tolerance to actually work.

    * The click-fit and resistance to popping off again, is due to 2 tiny little ridges on the inner faces, that key into grooves on the switch shaft. Molded in some very hard plastic. Good luck getting them right in 3D printed thermoplastic and not having them just flatten or shear off when pressing the button on.

    * The color and surface texture matching is critical for old gear historical restoration. I do not believe that 3D printing using commercially available filament could possibly get even close. And so there is no point whatsoever. Better to have no button than some bodgy crap-looking immitation.

    Thanks for the suggestion, but I think it was a knee-jerk 'off course 3D printing solves everything.'
    Rear feet and some other parts where color and texture don't matter, sure. I did see the thread on making parts for restorations when searching for sources. But not suitable for these.

    With all due respect (and I do respect you) you are wrong here. I've 3D printed the power buttons for certain hp equipment (see pic) and they fit just fine and look OK for my taste, but I don't feel the need to do more work to them. But if you want a near-exact copy then you must do more to the button!  :-\ You can't expect it to be that way right off the 3D printer.

    First, of course, you sand it with fine sandpaper. As you know, you cannot get the exact color filament off the shelf. So, you must prime it and color match it yourself with semi-gloss or gloss modelling paint. I know from years of model railroad modelling experience you can make it look almost exactly the same no matter what color you need! I don't want to start a big argument but you CAN make these parts look like near perfect matches.  :)

    For some of the smaller buttons it might make more sense to make a Silicone mold in lieu SLA or FDM printers in your collection. A lot of the ones I have made FDM was fine but it still has me considering an SLA Printer  :-DD Silicone molds with Epoxy is a great technique to learn and have in your bag of tricks regardless.

    Picked up my Makpac Boxes today and I wasn't going to pay the extortion for the trolley so with the help of someone elses box Cad model I knocked up the rest of the base and brought some cheap casters to make it tomorrow. Laser Cut Latches because I can  ;)

    But that's a different situation. I wasn't rejecting 'improvisation' in all cases. The buttons I need are tiny, precision, several are needed, they have to match exactly because they are right next to identical ones. And the equipment has historical interest.

    Your example... yeah, of course. Ironically I've just bought something with a missing power button. A HP 3326A, see pic. Also the switch shaft is snapped off. Improvisation is going to be required. Though I'll still see if I can find an original one first.

    Keith Rucker of VintageMachinery.org (ksrucker at Youtube) restores and maintains vintage machine and woodworking shop machines, like mills, drills, planers, and such.
    He's gone to the trouble of even casting new parts using self-made patterns (at Windy Hill Foundry) from cast iron, and often makes "new old" replacements using durabar (cast iron type product) et cetera, and fixes cast iron parts by brazing (as would have been done a century ago).  The most common problem does not seem to be the manufacturing step per se, but having the correct blueprints/dimensions of the part.  This is often excarberated by the fact that what remains is often broken, missing, or badly worn or pitted, so its measurements are no longer very useful.

    I personally really like the idea of using original materials and manufacturing methods, adjusted to tiny batch sizes down to singles, perhaps done even in a hobby environment, to replicate period-accurate new parts that are no longer available.  I wasn't trying to push 3D printing on you, I swear!  :D

    Now this I won't argue with. Last year I bought a giant milling machine, an Anayak FV-2V. It's _finally_ down on pads on the floor, in the right place, in my metalworking shed. It still needs a fair bit of work. For one thing it's missing one of the handwheels on the bed feed screw. Which is a real pain. Still thinking what to do about that. Casting a new one is among the options, and then there's the selective chrome plating on the outer wheel surface. Which the one chrome plating shop I've asked, claims 'can't be done.' Though it obviously can; just need the right surface masking coating during plating.

    I know exactly how it came to be missing too. The factory I bought it from when they originally fork lift moved it, had removed the handwheel to allow the huge machine to sit close enough on the forks. They moved the machine to storage, where it sat for nearly a year. By the time I bought it, they had no institutional memory of removing the wheel, or where they'd put it. Arses.

    I do want to get into milling (and casting) aluminium, especially funky enclosure lid-heatsinks for Linux SBCs.  Maybe injection molds for custom buttons, too.

    For that purpose in mind, I got me a 400W brushless spindle with an ER11 collet holder kit.  Includes the spindle, spindle bracket, the brushless controller, a small LED RPM display, and a AC-DC power supply.  Well packaged, except the four spindle bracket screws were willy-nilly in the box, so I stuck them in the foam.  Still need some ER11 collets and a dial test indicator to test for runout.

    A real milling machine would be niiiice, especially a heavy old used one, but they're rare here, and even harder to transport to the ice planet of Hoth (north of Arctic Circle), where I intend to do my milling for now.  (There is a Hacklab here in Helsinki with a CNC mill, and I'm a member.)

    It’s stored in the box with all the black first generation HP enclosure feet that are nearly always missing from instruments that we buy...

    Congrats on the mill - I hope you can come up with a workaround for the missing handwheel.  A Bridgeport is still on my wish list for someday.

    I bought a quickshifter unit for an S1000XR to retrofit onto my '15 S1000R which only has an up quickshifter. When I sent the ECU out to be modified to manage auto-blipping clutchless downshift it returned with their own quickshifter unit(300 euro value). It works really well. Added an Akropovic stainless steel exhaust also since I had it tuned at the same time.

    Bought the Siglent 1020X-E and modified it to the 300W model with full resolution. Works well but battery tests take long enough that I haven't been able to do a ton with it to get a full idea of how well I like it. Just glad it has a keypad.

    Garmin are pretty good in the respect. I have a 390LM which is about half a decade old now and I never updated the maps because it wanted  half my C: drive free space to do so. But I needed to last week and it wasn't a problem to get hold of the latest stuff. My partner, on the other hand, has (rather, had) a TomTom with lifetime updates. An email not that long after she got it said it's lifetime was exceeded and that was that! TomTom have form so it wasn't that much of a surprise.

    Riden RD6006P DC power supply. 0-60V 0-6A

    I was using a proper lab supply from the 80's. Works great, except that it has one dial for V for each channel and one dial for I for each channel and also good old needles for displays. It is not practical to set a specific few mA for playing with individual LEDs.

    With this new Riden, on the other hand, I can set 3.000V and then slowly ramp I up from 0.0010A to 0.0300A. I can graph P, I, and V right on the power supply and see the relationships between them. My noob dreams are being fulfilled: I graphed P, I, and V for a red LED and for a little 12V electric fan. I feel as though I have a new super power. This is the coolest TE I've ever played around with. A major reason for buying this model is that it is supported by both sigrok ( https://sigrok.org/ ) and HKJ's Test Controller ( https://lygte-info.dk/project/TestControllerIntro%20UK.html ). Additionally, the PC software that comes with this unit adds some nice capabilities e.g. automated voltage sweeps and exporting graphs. Forum user UniSoft has made a nice custom firmware for it, and sunkmail, et al. have written a manual for this firmware that looks more professional than the OEM manual. Loving it.

    EDIT:

    Order now and save 15% when you use code DUCKDUCK with my affiliate internet influencer snap-face-bay link. LOL. Seriously though, I think that I'd be over the moon with any power supply with a keypad. This just happens to be the first one that I bought. I'll have to start saving for a new Keithley source meter...

    Another test equipment museum piece. This time from the early days of logic systems analysis. A HP 1600A Logic State Analyzer, from around 1977. HP 1977 catalog pg 96, 1978  pg 124.

    Really happy with this. I've been looking for one in reasonable condition and nice price for ages, but on ebay that's rare.  This was US$70, and looked really clean. The seller prism_electronics7 packed it REALLY well, foam-in-place done right, plus the 1600A in it's own plastic bag. See pic 2 - I wish all sellers could pack right like this.

    It had one pivot cover on the handle missing, but I had a spare. Only needed a little cleaning to get the unit looking pristine. Inside there's virtually no dust, so maybe it wasn't even used much.
    None of the little HP buttons missing this time either.

    AND IT WORKS (mostly.) A few minor problems but I already have the op/service manual.
    The best surprise - the listing didn't show any probes although there appeared to be something inside the top pouch. Turns out it had all four probes, leads and clips. Amazing.

    So of course I got too pleased with myself. While reattaching the clear cover of the EHT section I fumbled a small screw into the interior. It shook out of the unit easily enough, but bounced off the bench onto the floor. Then took another hour and a half to find. Well, I needed to clean the floor anyway.  (Pic 3, spot the tiny screw.)

    Next historical boatanchor goal: A HP 5000A. See the HP Journal, Oct 1973. (last pic)
    Was that the first ever attempt at a 'logic analyzer'?

    I had a pair of the HP 1607A logic analyzers in the 80s, which were almost identical to the 1600A except you had to use an external scope in XY mode for the display.  I was impressed that the 1's and 0's are drawn in vector mode and generated with discrete logic.  It's great you got the probes.  All the probes for mine had been lost and I had to make my own.

    When the analyzers outlived their usefulness, our kids used them to control their cardboard box rocket ship.  They really liked the collection of knobs, buttons and switches (as did I).  (Sorry to those who think this is not a fitting end for vintage gear...)

    I have a 1607A too, though it needs repairs. So far I have no leads on finding the strange 'small BNC with three lugs' connectors, to make a 'trigger bus' cable between the 1600A and 1607A. Then there's the amphenol connectors control bus to look into.

    I have been looking at some better marking out gear for my old eyes (Timber, Plastic and metal) and decided my Piggybank wouldn't run to Incra or https://www.etsy.com/au/shop/MirockToolworks (https://www.etsy.com/au/shop/MirockToolworks) (could have designed and Lasercut my own but his are nice   :-  )

    So Aliexpress price point and save more $ for TEA https://www.aliexpress.com/item/4000338734447.html?spm=a2g0s.9042311.0.0.77794c4dKpx3Iu (https://www.aliexpress.com/item/4000338734447.html?spm=a2g0s.9042311.0.0.77794c4dKpx3Iu)

    Quicker, easier and cleaner to just swing a magnet over it.

    You missed where I said the screw is non-magnetic stainless. What do you think was the first thing I checked? (With the remaining screw.) Completely non-magnetic. With a captive washer. Quite a special screw, hence my not just saying goodbye to it and using a new one.

    Now to today's buy. Or rather today's arrival from USA.
    Back in 2015 johnh gave away some HP 6034A System DC power supply manuals. https://www.eevblog.com/forum/buysellwanted/(aus)-hp-6034a-hp-1727a-manuals/ (https://www.eevblog.com/forum/buysellwanted/(aus)-hp-6034a-hp-1727a-manuals/)
    I got one because these old manuals are are so cool, and also maybe I might find one of the supplies one day.
    Today's that day!

    It was cheap because "doesn't power up."
    On first quick inspection, it has a blown internal fuse on the mains input to the small transformer for the logic board power.

    A set of ten 36 inch leads, stacking banana plug to grabber. These are fairly heavy-duty, 18 awg wire rated at 4A. I have purchased the 18 inch version about 7 years ago and they are still good and used frequently.

    Not cheap, but probably good value.

    Beanflying,

    Take a look at 601W series. These are available from Digikey.com.au  If you buy 8 pieces you get free shipping.
    The 601W is the same grabber as the 201W, the banana plug is different.

    I'm amazed!

    Now into 2 minute teardown territory. Sort of lucky as QC is up to the $25 level too. Solderer #157 waved their tip near it at least  :palm:

    Wiring is 'sensible' for the current, flux ring on the Mabuchi540/Clone is nice to see as it generally bumps the efficiency and the torque.

    Thermal cutoff isn't an issue with the light trimming and only kicked in after 5 or 6 larger branches. If I was keen I would have broken out the pruning saw and kept going but coffee is important  ;) Compared to even a pruning saw the ability up a ladder to keep your body still and supported by one hand is the safety win. Last up the ladder lopping I did with a little Stihl 011 was way more sketchy.

    Re cheap table saws just DONT unless you want to be called Lefty :o Buy a cheap Tracksaw instead way safer and way more useful.

    Picked up this thing to satisfy my urge to work on some valves/tubes. AWA R7077 beat frequency oscillator. Basically two 100kHz oscillators (one variable 87-100kHz), a mixer and an audio amplifier in a box which gives you a 10Hz-13kHz sine wave output.
    First pic as it was listed - doesn't look too dirty here but it was filthy. Probably stopped working 20+ years ago and has lived in someone's garage ever since.

    Gave it good clean, replaced the line cord, some crusty internal wiring, a few resistors conducting less electrons than they should and a few capacitors conducting too many - kept original components where they weren't too far off value or where their leakage wouldn't cause a valve's bias to increase. The resistors in series with the rectifier and most of the resistors on the plates were burnt out, presumably because leaky caps were causing everything to bias too high. Someone has had a go replacing some of the resistors, otherwise everything including the valves are original as far as I can tell. Made in Australia circa 1944 :-+

    My first exposure to table saws when I was a teen had me thinking that way but now I have made my peace with them. Over the subsequent decades I gained enough proficiency by learning how to use roller exit feed extensions and the fences to tame the worst flaws of the saw type. I see track saws (which I like) as an adjunct. If I am home making cabinets the compact makita table saw I now have is still my go to primary tool.

    If I compared the portable makita  to a professional grade fullsize heavyweight table saw I have used  my toy comes off a poor second, but that just means the operator needs a bit more skill  to get good results.

    I suspect the table Saws being referred to were another level of 'quality' down again. The Circa $100 AUD ($70USD) and below stuff has no exit feeds and in most cases no riving knife or splitter.

    (https://i.ebayimg.com/images/g/tPoAAOSwJEpgdsqy/s-l1600.jpg)

    This one is our local bottom of the barrel big box ones 2000W and as flimsy as all get out on the sides tables for circa $150USD equivalent. Same importer/brand imports a very capable Tracksaw for the same $.

    There was a thread on cheap table saws for pcb cutting https://www.eevblog.com/forum/reviews/mini-table-saw-for-pcb-cutting-worth-buying-from-china/msg3591261/?topicseen;PHPSESSID=9dqtv92nl0abpi60hpes6e5vm7#msg3591261 (https://www.eevblog.com/forum/reviews/mini-table-saw-for-pcb-cutting-worth-buying-from-china/msg3591261/?topicseen;PHPSESSID=9dqtv92nl0abpi60hpes6e5vm7#msg3591261)

    https://www.youtube.com/watch?v=ny1kiYvyxmQ (https://www.youtube.com/watch?v=ny1kiYvyxmQ)

    I believe that is the model here - for US$110 https://www.banggood.com/Raitool-T4-Mini-Table-Saws-Wood-Working-Bench-Lathe-Electric-Polisher-Grinder-DIY-Model-Cutting-Saw-p-1190146.html?rmmds=product_topselling&cur_warehouse=USA&act_poa=SKU746927 (https://www.banggood.com/Raitool-T4-Mini-Table-Saws-Wood-Working-Bench-Lathe-Electric-Polisher-Grinder-DIY-Model-Cutting-Saw-p-1190146.html?rmmds=product_topselling&cur_warehouse=USA&act_poa=SKU746927)

    Last of my EOFY toy buy up arrived. Call me really happy given I swore off cheap cordless tools back in the NiCad era when Ryobi and a bunch of them really really sucked.

    Really Cheap and cheerful Chinese 18Ga bradder/stapler. Simply couldn't justify the $ for a Makita or similar. The 'sample' brads and staples went in the bin as they were horrid and rough (likely to jamb) and fed with some better grade 30mm long brads no problem when dialed in for depth. eBay auction: #131056994361

    Won't be rushing out to jump ship from Makita but a pleasant surprise.

    Some glue & stuff. Mostly for an attempt to fudge a replacement HP front panel power button. See https://www.eevblog.com/forum/repair/hp-3326a-two-channel-synthesizer-repair/ (https://www.eevblog.com/forum/repair/hp-3326a-two-channel-synthesizer-repair/)
    I found another button on something else that is the right size. I don't want to sacrifice it, so will try using it as a molding master. To end up with a cast duplicate. Going to be an experiment.

    Can anyone recommend a two-part epoxy casting material, that is low viscosity when liquid, sets hard, and can be spray painted?
    And a good mold release coating. Spray silicone?

    Also some pics related to the bench saws mentions above.
    I find my most useful saw is the slide saw in pic 3. It probably has a better name. The bit of plywood and clamped-on rear guide allow using G-clamps and bits of wood as hold-downs when cutting smallish bits of metal. NEVER hold small obects with fingers to cut it with one of these. They can rotate and jam the blade. You wouldn't believe how violent and sudden that can be. (Experience!)
    This is for cutting soft stuff - wood, aluminium, brass, and some plastics.
    Yes, I do have the safety shield clipped up out of the way. It's annoying, and I'm happy to rely on just never putting my hands anywhere near while the blade is rotating.

    For a table saw and router table, I improvised. Bought a cheap hand/plunge router, and the cheapest hand circular saw I could find. (It was VERY cheap.) Fitted them to sheets of laminex coated particle board (that I'd found for free), with some back-reinforcing beams. Use milk crates as a base. Two or four crates depending on how high you want the work surface. I made one control box with an on/off switch and emergency stop button. It clips onto whichever table I'm using. It's rare to need both tables at once.
    I have one planed-straight bit of wood that I clamp onto either table as a slide backing.
    Overall these take up little space when not in use, and the G-clamps, crates and back-slide all get used elsewhere.
    Mostly I set these up out on the lawn when I need to use them. They make a LOT of dust, and my 'really messy stuff' workshop is still unfinished (but progressing.)

    Btw, with table saws and routers, ALWAYS use two sacrificial pusher sticks to steer and push the wood you are cutting. Never fingers. Cut the ends of the sticks to V-shapes so they can grip on workpiece edges.

    Last lot of Epoxy I brought for some casting came from these guys eBay auction: #143806513270 also consider colouring the resin close to the final colour then painting. They also have molding Silicone and mold release. Should still be a few local bricks and mortar stores around Sydney depending on where you are if you take a look.

    Some good sleds on Saws help keep the pinkies out too along with push sticks blocks and feather boards. This one is a bandsaw sled (14" 1.5kW) for cutting 2020 Aluminium or thin timber/plastic strips.

    A HP 6623A triple output system power supply.
    'Bought' in the sense that it was free ( https://www.eevblog.com/forum/buysellwanted/fs-hp-6623a-triple-output-system-power-supply-free-seems-to-work-okay/ (https://www.eevblog.com/forum/buysellwanted/fs-hp-6623a-triple-output-system-power-supply-free-seems-to-work-okay/) )  but the related cost was US$450.
      ( $53  US postage, $348  Airfreight, reshipper fees,  and Australian GST on those, $49  Original service manual )

    It arrived today. Works, and is very nice! Thanks iroc86 !

    I think I know the general cause of the mystery 'error on channel 1'. I have a rule to ALWAYS open stuff up to inspect and clean before powering on. Learnt that lesson after A PC I'd picked up seemed to work OK despite a lot of dust. Left it on overnight thinking I'd clean it later. It was dead the next morning and had tripped the mains circuit breaker. VERY dead - a dust bunny in the PSU had caused a main cap HV DC arcover to the frame, and killed the motherboard.

    Anyway this HP unit was very dusty inside. An amount of dust that can cause strange faults on PCBs due to leakage paths.
    Didn't try turning it on till after cleaning. Everything I've tried works, and no errors yet.

    One minor thing - each of the three supply boards has three RIFA caps near the output terminals. So they are probably only subjected to low voltages. But still... They are starting to show a little of the typical cracking of the shell. To avoid sleepless nights I will replace them all. That will also allow for really cleaning the boards too, not just blowing with compressed air and a superfiicial light brush dusting.

    I have never purchased a new instrument for myself.  My bench is populated with ancient EBay instruments that generally required some form of maintenance before being usable.  One of those instruments is a HP 3457A multimeter that I had professionally calibrated at my local Tek cal lab.  While poking around a piece of equipment the input low lead hit mains hot releasing the dreaded smoke from my 3457.  Now having a gut feeling for what just happened and understanding the slim probability of successfully repairing my best bench meter I made a snap decision to finally get a quality, new multimeter.  Nonetheless, while waiting for the new meter to arrive I thought I would have a look at the 3457.  I immediately found 5 traces burned open and repaired those.  Continuing on I found 4 diodes shorted, a fuse open, and a shorted opamp.  I replaced all those and the meter fired up without complaint.  The self-test and calibration passed, and readings are still spot on.  In the mean time I have a brand new meter headed my way and it just arrived today to take a front and center position on my bench.  Now I don't need to break out the Fluke for diode and continuity checks any more.  Which is nice.

    Not a new purchase, a new gift, but I don't have it yet. Hopefully, there is no change of mind. I checked this out and it is absolutely amazing. Blaupunkt Ideal,: Barcelona 2340 - 1956/57. The care and design and functionality - astounding! The schematic is still inside and it works very well! I don't know squadoosh about old radio restoration, but this thing blows me away. Sheesh!

    Nice radio, DrG! The service manual is shown below:
    https://elektrotanya.com/blaupunkt_2340_barcelona_s-n_am-fm_receiver_sch.pdf/download.html

    A few weeks ago I got a nice one which, although not as pristine as yours, it is still a nice radio: a Philips 614B

    The quirk with the radio I got is that it has a complete different circuit than what is shown in the schematics and service information around the web. It was either a variant from the factory (it certainly seems very authentic and old) or was a retrofit to use mains power (the original was a battery radio).

    My unit uses 100mA heater "U" series valves (2 × UCH4, UBL1, UY1N) and the information around the web uses 1.4V heater "D" series (DK21, DF21, DAC21, DL21).

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1236273;image)

    I have only glanced it (inside and out) but the number of speakers (5), the band pass stuff, the point-to-point wiring, the "gauges" the planing (output jacks for several device to use the amplifier) - it just amazes me.

    I think that this is a relatively common model, but I am thinking pretty high end. There is a lot on it and I appreciate the link.

    I looked yours up and it is quite nice. In my case, the whole conversation started because he saw an AM/FM/SW radio (Si4844) that i built on a breadboard, where it remains. I mused that I always wanted to find an old radio cabinet and install it inside (sacrilege to some)...he said he knew of one that was being tossed. Well, that unit is far too nice, too large and works well - I would never do that - I meant a small blown one. But, I am happy if it works out!

    Again, I hope there is no change of mind.

    @thm_w, You are likely good with the big inductors. The half dozen MX-5x00 I have had open all had the inductors gooed, one by someone who was very, very, very concerned about vibration, or just angry that day :wtf:.  Top town it is usually not visible.  Nice machines.

    I bought some Panduit branded cable ties, I've always just used the supermarket or local hardware store generic brands. Now I don't know if it's just placebo but they do seem a little nicer ahahha.

    Kind of hard to find them in Australia so I just went to Arrow and sorted by price ascending. Two or three cents each isn't tooo bad.  :P

    Fun little selection guide to send you down a rabbit hole.

    This actually seems decent. You'll have to update us with the results in a few weeks when it arrives. Genuinely interested!

    So the new toys arrived a few days ago.

    Really nice to use and all came shipped in foam and cardboard boxes. Finish and accuracy is great fits a 0.5mm Pencil, marking knife or my Tungsten scribe nicely in the holes and slots. The edges and slots are crisp but not sharp and no burrs that are an issue to tear skin and make red stuff leak onto the job. The Squareness of the ruler guides has a little play to tweak if needed but if you want 'square' use a square instead then use these for marking out distances or just check the angle prior to use if it is critical.

    Nice addition to the tools anyway.

    I bought a used Agilent E3631A triple output DC power supply that looked like it had seen a lot of use, based on the photos. But what arrived was a Keysight E3631A instead, which looked as though it was never even used. The manufacture date was 2017. I'm not even sure when that power supply was discontinued, but I was totally chuffed to get a much newer and nicer piece of equipment compared to what I was expecting.

    Soo.. The 2-prong mains cable that is there is fitted .. by whom? Since there are NO traces of the dual insulation that would be a requirement for a Euro-flat-style plug to be allowed, I'd like to point out that such a device desperately needs a PE connection, and a 3-conductor mains cable.

    Interesting. I have the exact same solder pot (edit: No, but extremely similar - 100W 220°C to 480°C), but branded CMW. It came with a 3 way earthed plug: https://de.banggood.com/CM360A-100W-200-480-Degree-Solder-Pot-Soldering-Desoldering-Stainless-Steel-Plate-p-1045343.html

    A pair of ancient 5-1/4 FDDs: Toshiba 5471 L0K and TEC FB-503

    Both were reported as non-working, but upon closer inspection I can tell the TEC has residue around some recently replaced capacitors (by the previous owner). The Toshiba was reported as new by the previous owner and no residue is visibile - it might either be hidden under the ultra-small capactors (all 1980's ELNA) or simply a misconfiguration on its jumpers.

    It seems to be working okay. They give you very little instruction on how to use it and the software from u-blox was a confusing mess to get set up correctly. I don't know how well the built in antenna works other than to say, sitting on my bench for 20 minutes about 10 feet from a window it never got a lock. luckily I had also bought this separate antenna. I put it on the windowsill and within just a few minutes of hooking it up it was locked.

    No no, it's a solderING pot. Only for soldering. No unsoldering allowed!

    But seriously, apart from the fanciful lack of mains grounding, is that a crude triac power controller with no actual temperature sensor of any kind on the solder pot?  Really?

    Decided to take a look inside mine for comparison. Slightly better on the safety side. Case earthed (with an eyelet and screw!). Fuse in a holder, but similar "let's hope for the best" control circuitry with no feedback loop.
    Before you say "but they've put the switch on the neutral instead of the live", it doesn't make it any less safe when you have a German power plug that can be plugged either way around.

    Looks like a similar setup to the little "El Cheapo" soldering iron I bought at Jaycar a few years back as a quick " work around" when my Weller died.

    Maybe some supplier is stuck with a huge stock of those triac controllers unsold, as nobody buys lamp faders for home incandescents anymore.

    My first EEVBlog product arrived this week, an EEVBlog 121GW. Overall I'm pretty impressed with the meter, however one negative thing does stand out (mainly because Dave always makes such a big thing of it in his reviews of other meters): The continuity buzzer is painfully slow to react. So much so, that the meter is definitely not suitable for reverse engineering, when you want to slide the probe across the pins of a chip to find a connection.

    Surely this could have been improved?

    Not today but I recently bought 40 acres of offgrid land. :D  Goal is to eventually build a homestead, maybe move there.    Took the pic today.  Not exactly electronics related but figured I'd share.

    (https://gal.redsquirrel.me/thumbs/lrg-5190-img_20210809_1153184__copy_.jpg) (http://'https://gal.redsquirrel.me/images/other/random/img_20210809_1153184__copy_.jpg')

    A bit more electronics related, very recently also bought a 3kw inverter which came in today. It's from Amazon so it's a big gamble, I'll have to put it through some stress testing.

    (https://gal.redsquirrel.me/thumbs/lrg-5185-img_20210809_1726234.jpg) (http://'https://gal.redsquirrel.me/images/other/random/img_20210809_1726234.jpg')

    I kind of need a 24v power supply to drive it, so I also bought 4 golf cart batteries:

    The charge controller I have can do 12 or 24 volt so will just be switching everything to 24v.  Might rewire the solar panels so they're in series, but I might be ok with them as is.

    It may seem ass backwards but the inverter and batteries will be for my shed as the current solar system is kind of just thrown together on the floor not even properly wired.  This new one will be properly wired in a nice cabinet on the wall with a small sub panel and designed to also act as backup power for the house once I run a feed to a separate panel inside the house too.   The old system will be going in the black box below which is a portable system which I'll bring to the off grid property.   Basically to charge power tools, chainsaw etc when I'll be working there.  Once I actually have something built then I may swap the systems around or at least the inverters.  So in a way putting that inverter in the shed will be a good way to test it and if it works well I might even just buy another.  They have good reviews, but kinda have to take that with grain of salt on Amazon.

    With all this spending lately I can't afford a haircut.    :p

    A Burster Resistomat 2318 milliohmmeter.
    Due to poor packing and old plastics it arrived with a shattered front frame.

    I don't have much experience with Kelvin clip measurements but noticed that rotating one clip 180° gives about 3mΩ difference on the measurement.
    Do any milli / micro ohmmeters do this automatically allowing for zero adjustments with current injection and voltage measurement "diagonal" or "parallel" WRT the clips and average out both while actually measuring a conductor?
    (If that makes any sense?)

    The other day I pulled the trigger on a Flue 8100A nixie dmm.  Paid too much but if you're going to use a bench meter I'll go for the cool factor.  No doubt it's another repair project.

    Unrelated to that, I just bought a pallet of used solar cells with the aim of eventually going off-grid (If you connect to the utility, they will tell you the maximum amount of power you can connect and they now charge you for every watt that crosses their meter!)  That's a long term project but the panels were about a third the price of new ones and I couldn't pass them up.  The real money will be in the batteries, inverters and control electronics.

    Here, the utility is required to swap your meter if you become a "micro-producer". There are tax incentives as long as you stay under 63A mains fuses (this is Real Voltage Land, so that's 3 phases at 400V, i.e ~43KW as three 1-phase loads (most houses here are 3-phase 25A). There are a few other limits like KWh per year and profit limits; once you go past them you're a small business and must deal with VAT et al. If you're a farmer, or like Red Squirrel, own a piece of forest, you already are in small business land; you can't do those only as a ordinary worker/salary person.

    I bought a rack-mount power strip with individual switches. It's a Pyle PDBC70. It cost about USD60. I opened it up and was pleasantly surprised that it was well constructed. I am using it to switch power to my test equipment (and powered speakers) that have power switches on the back. I'm looking at you, Riden RD6006P and Rigol DG1022  >:( I'm also switching a high-voltage power supply -- HP 6209B (to make it more difficult to accidentally switch on) and my soldering iron (to make it easier to ensure that it is off). I also bought some more NiMH 9v batteries so I can remove the potentially leaky alkaline battery from my DER DE-5000 LCR meter.

    I don't really care about if my power strips are fancy or not. But functionally those Pyle's look to be much better than mine which have the typical socket and switch all on the top side. I'd much prefer that Pyle design, so I can mount it like that photo and have all my power cables out of the way, and easily see/switch the devices I want to. I can't imagine it costs much more to make a power strip like that either compared to the typical design. Unfortunately, I've never seen Pyle's or anything else of that style here, and not keen on paying an arm and a leg in shipping/customs fees.

    I was looking for a solid frequency counter for basic audio repair. I found these AN/USM 459 (HP 5328A) counters on Craigslist.

    They are used but were rebuilt and vacuum sealed from 2013 in foil from the Tobyhanna Army Depot Calibration Center. includes options H99, 10. Oven oscillator, GPIB, and "C" channel (500 MHz). Each comes with extra fuses, extender cards, a power cord, and a printout of the calibration results.

    The seller in Columbus, Ohio still has one or two left. I bought two since he's asking $45 each.

    If I could get full root on it, or replace the OS with one of my own, I'd be excited to get one.

    Alas, it looks like they operate similarly to e.g. Allwinner, and consider copyrights to be something they can ignore but others have to respect...  All they admit is that it runs a purpose-built Linux distribution ("Codex"; never heard of it, neither has Distrowatch).

    Surprising, considering it is a Norwegian company (Biermanns gate 6, Oslo, Norway).

    Snif, snif.  My nose says the way the device is tied to their Cloud Service, is something the company would rather not have publicly known.  Smells like backdoors and bad security, not like "but the EULA says all your artwork belong to us".

    Bonjour a tous:

    Here is the   Keysight (ex Agilent/HP) 34465A, 6.5 dig  meter current catalog.

    https://www.keysight.com/us/en/products/digital-multimeters-dmm/truevolt-series-multimeters.html (https://www.keysight.com/us/en/products/digital-multimeters-dmm/truevolt-series-multimeters.html)

    One year old,  slight cabinet dings, no IEE 488 but otherwise in CAL and super condition.
    Still  discovering all its capabilities ....Web IP addr interface, data logging and screen capture.
    Need to upgrade my CAL standards and Verfs....

    Your thoughts?

    Bon weekend

    Jon

    Rebonjour, a few more notes....

    1/ LCD display is bright and clear but has a vibration intermittent, goes totally dark sometimes even though unit continues to run and can be controlled by Ethernet.
    Perhaps a bad display or front panel PCB?
    Just  returned to Keysight for warranty service.

    2/Unexpected features: Freq counter, capacitance, Data capture.

    3/ Options  activated in latest FW, 2M memory instead of stock 50K.

    4/   IEE488 capability with added interface.

    5/ Total control and data/screen capture over Ethernet.

    6/   7.5 digits c display with slow acq and smoothing, but Vref would need upgrade for accuracy

    7/ Checked  all my  lab standards
    R (10 Ohm..100 MEG JRL, GR, etc)

    Capacitance (GenRad 0.1/0.2/0.4 and 1000 pF)

    DV V (, LM399AH, Yokogawa calibrator, HP 6115A)

    AC Volts (TEK PG506)

    every test is beyond the accuracy of my lab standards or equipment.

    Any others here have Keysight TruVolt series 34460/61/65/70A?

    Bon Weekend,

    Jon

    I bought a new phone today. A OnePlus 9. It charges the 4500mAh battery from 0 to 100% in 29 Minutes. That seems like an awful of energy to be pumping into a dead end. I wonder how many cycles of that type of abuse the batteries will survive? But just looking at the charging cable, you know they mean business. Here's the cable next to a standard iPhone charging cable.

    Not sure if this is the third or fourth mortgage on the left Kidney but I brought a box of Beer and a near size matched AC/DC Tig with all the trimmings. I have put off buying one for a very long time and justified NOT doing it as 'it only costs me $X a year to pay but I have a few really heavy but still fiddley jobs that will likely need a few changes on the fly or even post construction if needed here so partly it will save lift gate or a hyabb delivery at the conclusion of construction.

    I have some similar tig welder, problem is you need a gas bottle that is almost as expensive as the welder ...

    Not so much in this case as the Welder and a few bits was nearly $2k AUD.

    The first fill of Argon (E size) was $430 (circa $320USD)and the refills are about $160 AUD (about $120USD. So I now own an exchange bottle from supplier X.

    Going back 30 years ago locally the only way to get Gas was to rent the bottles instead of 'buying' one which for a home user with a low turnover of gas became a major negative of Oxy/Acetylene, Mig and Tig. Rental from memory was around $80-90 AUD a year per bottle.

    Fairly similar features by the looks of it. I got mine with a good foot pedal, helmet and nearly 10kg of various rods plus some spares which pushed the price up.

    Now because I own a TIG welder I can build the cart I need to put the TIG welder and bottle on therefore the purchased was obviously required  ;D

    Front edge is nicely ground and on a quick check better than the spec and the back edge is milled and I might clean it up closer using the front as a reference.

But alas, the deal fell through, and my I've still not used most of those miles.

    Today i joined the Kunkin electronic load club - junior member KP182. Came in reasonable time from order (Banggood) and looks in mint and robust condition. The banana jack sockets are fine for my 4 mm plugs (some Youtubers were indicating theirs were loose). Plugged it in and had a quick low power play with the controls - intuitive user experience (after watching plenty of unboxings).

    Sadly one of my "electronics" book orders I was expecting from one of the big secondhand book sellers seems to have been cancelled today. Doesn't happen often but is always a bit of poor consumer experience.

    Hello everyone!
    So today I bought a NOS rebranded digital multimeter, by a now dead electronics company, sold by a used gear broker. It is a "custom" version of the quite ooold 50k counts Mastech MS 8218, custom being the color blue instead of green and of course the IS logo on it.
    I actually know zilch of the company that imported this DMM in Italy, however the price was so frigging good (50 Euro each) for the DMM, nylon carry bag, reasonably good probes, the optical to RS232 cable for PC connectivity and SW CD,  that I purchased two of them!
    I took some pics of the DMM as it came  - it even included six AAA batteries, that obviously leaked, luckily they were inside a plastic bag so no damage done. These DMM must have been in storage for a huge amount of time.
    I could not wait so I compared the 10K "reference" resistor I built some time ago and a 10V LM399AH based "reference", with a calibrated Agilent 34401A; the results are quite surprising, the thing seems to be good! Caveat, I had not done proper burn in or let anything heat up for hours, the 10V ref was on for just 20 minutes, and the 34401 as well.
    All in all I am really happy about these meters!

    Edited to remove duplicated pic

    That is a nice thing. Also the kit of pin headers you get along with it. You also do PCB design? That is the main application is suppose?

    You might also consider buying a headband magnifier for inspection. Maybe a bit more practical.

All cased in original case, meter sealed with USMC TMDE CAMP cal sticker. Original case, tagged with USMC inventory tag, shipped in original Fluke carton.

    I took the battery out and tested how it performs on solar only. It will turn on at ~70lux but dims the display or shuts down on operation. It works flawlessly at ~120 lux.

    Works wonderfully as a desktop calculator. Feet are nice and grippy so it doesn't slide around, and the LCD is slightly tilted and the bias is set so it stays legible at shallow angles.

    Grr they used a cheap arse LR44 alkaline, I will change it to a SR44 cell when it dies. Rated battery life is 3 years @ 1 hour per day so with my usage maybe it'll take a decade.  :P

    I have a sharp twin power solar/bat EL-540D purchased in around 1985 with a thoroughly dead battery. I relegated to the back of my desk drawer because it would never work under incandescent lighting. Then one day out of boredom I tried  it under a desk lamp that I switched to soft white LED.  The bulb is a pretty weak-ass 9W cheapy.

    I have a pretty old Casio fx-991ms that has a similar setup as yours with the solar cell and an internal battery.
    The about 10 years ago I noticed that the moment I would put my hand over the solar cell it would die. I opened it and the cell was easy to change. It was a bit bloated and crusty at the seal but no visible damage around to be seen.
    I would suggest that if you like the calculator it would be wise to check the battery.

    A lucky find of an old Pioneer guillotine from a junk shop while visiting my son this week. I'm not sure how old it is, probably1940s - I haven't found any reference on the web yet.

    The cutting width is only 42mm, but from the solidity of its construction, length of lever, and toughness of the blades, it must have been designed for steel. I've dismantled it, cleaned it, given the blades a quick hone, and re-greased it. It cuts non-ferrous and FR4 like butter, no tendency to tip even tiny unsupported pieces. It will be just the thing for cutting metal strip to length and trimming bits of PCB for Manhattan style construction.

    That big Mahogany block is probably going to get replaced with something less valuable too.  :D

    Wohooo IKEA NiMH batteries still made in Japan. (I know it was confirmed by other members but it's great to receive the good stuff in case they do a switcheroo)

    For context, there is only one NiMH AA/AAA battery factory in Japan, the FDK facility. So if you ever find some rechargeable batteries made in Japan then you know it's coming from the same place as the eneloops. I don't think they use the cutting edge chemistry for the rebrands (no way they do binning right?), but I've tested the capacity to only be around 1% lower.

    Either way they are excellent cells, especially for the price! (half the price of eneloops, if that)

    Nice little machines, I have a T420, X230, X240. You can sometimes find them stupid cheap on the second hand market. The old 7 row keyboard is fantastic isn't it?

    There is a very enthusiastic community of ThinkPad modders in China, they are designing 'modern' motherboards that fit into the old chassis. You can also get display converters so you can swap in a modern IPS display (LVDS>eDP converter, though some of them just steal the signal from the dock connector). I have one but haven't gotten around to installing it yet on the X230. (they also supply a CNC cut bezel to replace the old one, it's crazy!)

    I installed the 12" MacBook speakers in my X230 and took measurements as well, I think you can probably count the number of laptops on the planet that sound better than it on one hand.  :P

    Five BF245B for less than 60¢ a pop from, up until then, a reputable local brick and mortar shop.

    All of them fake. Not even JFETs, possibly BJTs. Too good to be true.

    Told them about it. They said they don't verify if what they are distributing is really what it says on the package. If more people complain they will pull the item from their shopping engine.

    Returned the items, got a refund. Learned my lesson.

    I ordered a 30cc tube of Amtech NC-559-V2-TF flux from Louis Rossman because he's selling it at half the price compared to everyone else ($17.99 vs. $34.99).

    Processing of the order was very expeditious... I placed the order at 9:43 AM and at 11:06 AM I got an email saying the order had been shipped.

    $40 mouse pad made in Japan...Artisan FX Zero. Worth every penny!  :P

    The soft rubber base is spectacular, it sticks to the desk very well. I'm not much of a gamer any more so I wanted their slowest "control" pad for basic office use, it's still faster than most cloth pads while being very comfortable, I like it a lot.

    Last time I used a mouse mat was, er, a very long time ago and I kind of assumed with the laser stuff nowadays a mat wasn't really needed unless you have a glass table or something.

    Logitech G304, just a nice little wireless gaming mouse that runs off a single AA. I kind of hate "normal" wireless/bluetooth mice because of the slight lag, so you almost "have" to get a gaming one to eliminate it.

    A mouse pad isn't strictly necessary because of tracking issues or anything (modern sensors will track on damn near anything), it's just a preference thing. I always use mouse pads because it's quieter, smoother, doesn't bust up the mouse feet and it protects your table too. I really like the "stopping power" of a cloth pad.

    It's more about smooth movement and extending the life of the pads on your mouse. This depends on the mouse as well, but for example on Logitech MX master 3, pads are not too forgiving.

    But with some gamers the mat philosophy is getting close to audiofoolery.

    I'm addicted to the Logitech auto-hyperscroll thingy so some flavour of MX has been my weapon of choice for some time. I use it on an MDF worktop and although that's now very very smooth to the touch the mouse feet don't seem to have suffered. Perhaps I'm not pointing enough :)

    I am a big fan of good mousepads as well. I have been using the 3M below for several years now and I noticed a better control for CAD - however, the mice I like to use are a bit older (Logitech M510) and therefore might not have sensors as advanced as the ones in newer models.

    Hi,

    Here is a "new" Tektronix 316 Oscilloscope :)

    It was dead on arrival, of course, and was quite dusty. I washed it in the bathroom and let it dry for 10 days.

    I started by checking the power supply : almost all electrolytics in this section were bad. Once replaced I did obtain a spot in X-Y mode ! Better : by using the calibrator output, the spot moved in both directions.

    Schematics found online are not for my old unit : Tektronix made a lot of changes. I was fooled thinking that even if the tubes was not the same, waveforms should be similar... Eventually the 317 schematics showed me that the waveforms I have in my instrument are perfectly OK with this tube set.

    Focusing on the time base, I noticed corroded legs on two NE2 neon bulbs. These are hard to find but they are said to be replaceable by a 82 volts Zener. I used 3 22v and 1 18v in series to obtain an approximate value. And the time base started to work again !

    Next will be to take a look in the trigger section : in many time/div positions there are multiple traces on the screen, and they are not triggered at the same point.

    Also some black beauty to replace but as it now kinda works il will be easier to do it a step at a time.

    Thomas

    My heavily used M510 gets used straight on the cork top of my bench and the pads seem fine. I was using a mousepad prior to adding the cork but they chew up desk space so I got rid of it. Secondhand 3Dconnexion is settling in well with the CAD workflow after some early brain/hand interface issues.

    Mouse pad... I have one that my younger son donated to me - it's 36" x 16" and the keyboard, mouse, laptop and more fits nicely on it. Has a soft compressible feel and is cloth covered and antislip on the back. Been using it daily for a month or so and I'm sold on the concept! Great for the mouse and comfortable (not cold, not hot) on the wrists etc.

    Younger son is a keyboard nerd - there's a custom keyboard subculture - we're talking about finished keyboards that range into the thousands of dollars  :o so the mouse pad is part of that 'madness'  :)

    I do a fair bit of cad (schematic, layout and some mechanical) and having a large pad under the whole workspace is very nice indeed.

    cheers,
    george.

    Bought this flash unit at a local university garage sale mainly for the zip cord because it was dirt cheap.

    When I got it home and opened up the battery compartment (which had been modified for an external power supply) I found some "0V" AA batteries that look like they were milled on a lathe. That made the purchase even more of a bargain.

    Purchased some more holes in 8mm 304L for the fixtures on my welding table. DXF sent 'please make one of each' thinking that will avoid errors at the Waterjet cutter with quantities. Received back  :palm:

    On the plus side the tabs and slots are spot on and the holes are just on 0.05mm under the 20mm ready for a tweak to size with a reamer.

    That solution for thick plates also was tried by German engineers in welding armour plate on the Panther and Königstiger tanks. As they'd copied the slanted frontal armour from the T-34, they needed a way to have the plates supporting each other mutually and box joints (on the upper side a 150mm face hardened armour plate joined to a 100mm one for the lower part) were chosen.

    By that time in the war, they were running short of alloy metals and experienced workers, so the heat treating crucial to a working armour plate was not always successful...

    It's not too bad. Has been left somewhere with some humidity. The two rusty screws on the front bottom corners of the CRT are 'blued steel' and that always rusts at the drop of a hat. Just replace them.  The carry handle body, that looks like rust, is actually rubber with severe mold. It might clean off pretty well. The probes have bad 'soft plastic decay' and mold, but you can throw them away and get new cheaply. Other than that, just some standard cleaning. The delay vernier dial has a little aluminium corrosion frosting, might clean OK.

    You might be lucky, and have a 'low price because looks horrible, but easily fixed up' score.
    Inside the scope is probably OK, but best to give it a good long bake out before powering up.

    Technically this was bought with the time it took me to get it out of the dumpster.

    NIM bin, modules, MHV SHV and BNC cables, a xenon proportional counter and Canberra 2006 charge preamplifier,
    And some miscellaneous instruments. One of homemade and soviet origin

    Everything works and the detector/preamp amp combo gives beautiful gamma spectra!

    I am super hyped!

    Not today, but last week, I bought some heatshrink tubing, some TO3 mica washers & spacers, a knob to fit a 1/4' shaft pot, & a useless coax crimping tool!

    The one I've used for years has disappeared, so I needed another, & bought this thing from Jaycar.
    Problem is, it doesn't crimp, running out of travel before it can do so! >:( >:(

    Which one ?
    Recently got their TH1846 but not used it much yet.
    Figured the handle is a generic type that will take the many various crimp heads/dies that can be sourced online.

    Don't like the look of that one much and think TH1833 would be the better choice as those and 1846 have the fine adjustment.  :-//

    I got it 15(?) years ago. I'm not sure if the ratchet one was available. I recall needed it for just one wire and meant to pick up something better from the wholesaler when convenient. Apparently I never did get around to it. I only ever needed to run coax in the walls for people ahead of a pay-tv install as those fitters would only run coax surface.  >:(

    Someone else usually terminated the ends. The rare few I did do, I remember wishing and wanting.

    The ones at all my jobs had proper self-evident adjustments, & my only "El Cheapo" (the lost one), worked OK from scratch.
    The only thing that looks like it is possibly an adjustment, is a small hole next to one of the pivots.

    I will have another look tomorrow, & if I can't find any adjustment, back it goes.

    That finally happened! I found OPA2192 on lcsc, they had 10 pieces at stock. I was looking for it for months. How hard would it be to find an opamp these days? To my surprise, it was out-of-stock everywhere for months (except some obscure to me dealers).

    Even on ti.com it is out-of-stock since a long time ago.

    I bought one of those only to find I much prefer the Goot GS-100 one I already had, but the silicone tube gave me an idea so I bought some of this...https://www.aliexpress.com/item/4000833290804.html?spm=a2g0s.9042311.0.0.27424c4dJQX5aa (https://www.aliexpress.com/item/4000833290804.html?spm=a2g0s.9042311.0.0.27424c4dJQX5aa)
    I got three different sizes of tube to find the best fit, 1m lengths at $1 or $2 a length is enough for a lifetime.  Don't waste your money buying the 2 inches of replacement tube SS-16 https://www.tme.com/au/en/details/fut.ss-16/desoldering-pumps/engineer/ss-16/.

    If these are well built and the plunger does not go flying away, then it should be a matter of paying attention...  :-DD

    I have been using these desoldering with no guards for many years and the best feature is that, for the big jobs that require many operations, you can rearm it in your own leg and speed up the process considerably without the fatigue that overcomes your own thumb on the enclosed ones (I am talking about hundreds of operations when disassembling boards). The Edsyn Soldapult has a more or less open design but the back of the plunger has a very small area that allows you to do this only a handful of times before your leg starts being sore.

    I find that heating up my old 707 takes 10 minutes, but my Pace or Ksger irons heat up in seconds, so I use a solder sucker for few pins.

    With SMD being rather common now I find I use braid rather than a sucker on pads, and for the relatively few PTH my Denon 7000 is fantastic. But it takes a few minutes to warm up, and something handy to use quickly for the odd hole might be nice.

    What I noticed about my 707 is that once in a while it will blow out before starting to suck, creating solder splatters.

    I don't know if that's because it's old, or some sort of flaw because the motor never stops in the same place in the pump cycle.

    Post by: PlainName on November 03, 2021, 09:06:30 am
    Might be a feature! The Denon can blow or suck so you can use it as a hot air gun, but typically I put it on blow after sucking to clean out the tubes before turning off. Maybe they slipped that into the 707 as an easter egg :)

    I had to buy some replacement pre-filters for the Inovaair E7 air purifier so I might as well give a mini review after living with it for about 9 months.

    Fan is a ebm-papst R2E190-RA26-51 made in Germany, rated 57W but the unit seems to under drive it at 36W on high. This fan is like ~USD110 on Mouser so I seem to be getting my money's worth haha (purifier was ~USD510).

    Chassis is 5052 aluminium, with a Dulux powder coat outdoor rated for 10 years, so will last ages indoors according to the manufacturer. It has held up just perfectly fine even if I use it as a makeshift nightstand.

    Run capacitor is a Hydra MKP series, 400V AC @ 30,000 hours 85C.

    Crimp terminals are TE Connectivity/AMP nylon, quite impressed they didn't just use some cheapo PVC rubbish. Interesting that they soldered the earth wire on the IEC inlet but used crimp terminals everywhere else.

    Latch is branded Nielsen Sessions, it's very sturdy. The plastic carrying handles are branded Elesa Italy, made from PA+GF (polyamide with glass fiber)

    The main HEPA filter is rated for up to 3-5 years (USD145), thanks in part to the prefilter which has to be replaced about every 6 months(USD18, not tooooo expensive). They say you should replace the prefilter when it gets 2mm of dust buildup which was 9 months in my little bedroom though I could have stretched it some more, it's kinda hard to eyeball.

    The unit itself is made in Australia you bloody ripper. Everything looks easy to replace/repair so it will last a lifetime, none of that microprocessor controlled smart bluetooth consumer garbage with RFID-tagged filter replacements ahahah.

    You know I actually had a little buyers remorse just after ordering because maybe I should have bought a cheapie $200 Xiaomi purifier or similar instead, but after using the air purifier and doing the teardown I think it was worth every one of the 700 dollarydoos.  ^-^

    It indeed seems high, but last year I did an extensive research into air purifiers and that is the ballpark for something that will actually do anything for very small particulates and macro molecules such as volatile compounds, mycotoxins, etc. (having a family highly allergic is a PITA). Back then I got an Austin Air purifier with a 15 kg of activated charcoal and zeolite on its main filter.

    Yep seems crazy huh? That's getting into small split system air conditioning territory.  :P

    The common "high end" brands like Blueair or IQAir Swiss air start at $700 for their smallest units and easily go into the $1.5k range. I don't know how much of that is typical overseas price gouging, but properly rated/tested air purifiers are bloody expensive.

    I was quite surprised to find a local brand that is quite competitive in price/performance.

    If the last pic is what I think it is, a vacuum chamber with triple inlet at end, with four more inlets, one pair perpendicular to the chamber axis, and the turbomol pump is in the two assemblies at the bottom, I'd say so.  You'll still need a pre-vacuum pump, some pressure sensors, and miscellaneous stuff, but that's a pretty good start for quite a few (small-sized) vacuum experiments.  Perhaps even a small fusor.  (I know nothing of the engineering use cases.)

    Black & Decker handheld vacuum, destined for the garage.

    I acquired the 10.8V version of this a few years ago, on a deal, for my bench. Not a huge capacity but for cleaning dust and swarf and little bit of wire it does the biz. The side hatch flips open for emptying, and the entire side rotates slightly then just falls off for cleaning (it and its filter) under a tap. There were two annoyances: first, the supplied nozzle is just wrong - if it didn't include the brush part, that gets in the way when stowed and is useless when not, it would be better. I wound up 3D printing a proper crevice nozzle.

    Second, the battery life is fantastic and you can leave it plugged in forever without it overcharging. But it's a (special) plug in the back and sometimes I forget to take that out before walking off with the thing, and there's enough loose cable to get up a head of steam before it pulls back.

    This version is 18V and allegedly twice the sucking power (not that it needed more, but I won't argue). It comes with the silly nozzle but now also with a proper crevice tool, and there is no plug - couple of spring contacts on a (new) base plate. Wondering how long they will last,  but I just spent more than a few minutes putting it down and lifting it away to see if it would land in the wrong position to charge. Seems fine  :-+

    Stupidly expensive, even with nearly 50% at Amazon now, but it is unique and I like it. More importantly, there is now no excuse for Someone Else to leave sawdust all over the bandsaw and pillar drill :rant:

    Perhaps not a Tokamak, but a Fusor isn't that difficult to build as plenty of amateurs have built one. A Fusor is a fusion reactor that uses electrical fields to fuse deuterium into helium.

    Probably that. I rarely use braid on PTH stuff but use it a lot on SMD pads. No other way to get the pads clean, ISTM - a solder sucker, even my wonderful DeNon 7000, always leaves some ripple and sometimes sucks up the part you wanted to keep ;)

    Put a bid on a Time Electronic Micro Cal 1030 and won it, assumed by the listing it was just a random person
    selling it from home.

    Had a delivery today and was really puzzled to what it was (Also excited, thought I'd won a competition or something) as it was from Audio Technica. In a really professional looking package with a pull tab etc.

    Opened the packaged and it was the Micro Cal 1030, I really wasn't expecting that! Seems well looked after and threw it on my newest Fluke 87V for a quick test and seems to be working OK.

    Never installed one before. Went smoothly. Did my reading (background and instructions) before hand (yeah I did watch a few vids). Used my non-contact voltage detector (before and multiple times after turning off the breaker) and my socket tester. Correctly identified the feeder lines. All went well!

    ...and..sadly also one of these

    Bought this as a stocking filler / drawer filler / 'toy' for myself. It is an Adafruit board but I bought it off of Amazon because, while the price goes up a few bucks vs. their site, the free shipping makes it a good deal for me.

    That being said, I think I will use it in a project and of course there is a story with that :).

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1353053;image)

    A while ago, an issue came up where there was a question about how long it took to get hot water out of a tap (long story and it is not my problem). So, in an evening, I slopped together a DS18B20 on an UNO clone and added an SD and display (see pic). A simple and easy temperature logger that could be used to actually measure how long it took. I attached the sensor to the tap and pressed a button, turned the tap on and waited and then read/graphed the data from the resulting file. Gathering enough samples, I had the data needed to make a point, so to speak. This worked quite well and, like many such projects, it found a home in a box still on a breadboard and with no case and so on.

    Been trying to work on that :) So, I thought about cleaning it up, adding a few features and putting it in an enclosure. One of the features (and many could be added) was to also log ambient temperature, in contrast to a remote temperature. I actually had a few different kinds of temp sensors but not an MCP9808, and...now I do.

    Further, I get annoyed when two or more temperature sensors laid side by side give me different readings - such is the nature of sensors and 'accuracy'. I think I have a good working knowledge of calibration using standards and I have looked into buying a 'laboratory-grade' thermometer - traceable and all that. It got pretty mind-numbing to investigate and, potentially, expensive and given I only use maybe -5 to 120 F as an absolute range, I just never pulled the trigger.

    In this case, however, I may calibrate the remote DS18B20 to the MCP9808 as the poor-man's standard (I may take some heat for that, but as long as it is not just trolling, I will read and consider). At the least, I will look at side by side readings for the two over a range that I can easily accommodate.

    Not sure how far this will go, but that's the plan and the story and I'm sticking to it :)

    Well, I've been trying to buy one of those "multi function component" testers from Amazon.
    The first one I ordered was "destroyed by customs in China" according to the vendor. They graciously informed me and refunded my money and suggested that I "buy one locally" because of supply chain issues.
    So I found one that was "fulfilled by Amazon" and it came today... In a static bag which as inside a padded envelope with other stuff... And yes, you guessed it. The display was broken:

    I got myself a Christmas present--has nothing to do with electronics--an Umarex Ruger 10/22 Air Rifle:
    (http://www.paladinmicro.com/images/Tools/Umarex1022OnPorch-00.jpg)

    It looks just like the real thing, but weighs a pound or so less at 4.5 lbs. Accurate as heck, even with the iron sights and my 74 yo eyes. It takes two 12 g CO₂ cartridges and has a 10-round rotary clip in a magazine very much like the real rife--I've already taken out some "tree rats" at 10 m or so--I LIKE it!

    Just $49.95 (less than ½ the list price) from Tractor Supply (https://www.tractorsupply.com/tsc/product/ruger-10-22-pellet-rifle-2244233); with free "ship-to-store"--I think it's on sale for another week or so...

    If your sensors are up to it, cold water with crushed ice is a good start for 32'ing your sensors.  NIST have made public a number of demonstrations, and here's a video version:

    3 Syringes was $48, shipping $55, tax and handling $40 so a whopping $48 per 10ml syringe instead of $16, uhhhhh just wanted to try it out but this is not for repetition.

    This brand mostly focusses on the professional automotive tools market. It is not the first tools I bought from this brand.

    It's a consequence of acquisition methods that I've got better structure for my AF and W inch-system wrenches than my metric ones. I bought both AF and W as sets, while I've been assembling my metric sets from used and new piecemeal purchases.

    For sockets, it's a bit better; I've got strips of AF and W complementing a full metric Bahco socket set, all in 1/2" (some of the AF sockets are 1/4") and a full metric set in 1/4" from Kamasa. All have been enhanced with higher-quality parts where wear or other needs so dictate.  I obviously need a 1/4" set in BA too.

    After an unfortunate accident with a cup of tea and a HP EliteBook 840 G4 (which by the way works very well in Linux), a new keyboard module (HP 836307-B71) for 80€ shipped. :'(

    I was worried for a couple of days I lost the entire laptop, but after a teardown and careful cleaning, it works fine.  Except for the keyboard, of course; but it wasn't an OEM, a cheapie eBay replacement with Danish layout, and apparently not at all protected against spills like the original is.

    - Intel Celeron Dual-core N4020 @ 1.1Ghz
    - INTEL UHD Graphics
    - 4GB of ram DDR4
    - 64GB of SSD
    - 14 inc 16:9 LCD 1366x768 pixel
    - 1 USB 3.1 Gen 1 Type-C
    - 2 USB 3.1 Gen 1 Type-A
    - 1 Smart Pin CA
    - 1 HDMI 1.4b
    - UK layout keyboard and precision Touchpad
    - Wifi 802.11a/b/g/n/ac
    - Bluetooth 4.2
    - 41 Wh Li-Ion battery
    - 324x179x225 mm, 1460 g

    HP 14S-DQ0035NL-14, brand new for 120 Euro (instead of 250 Euro) without Windows, that I don't need it in this case. There is no Ethernet port, so I need a USB-to-Lan adapter, it will be the perfect text and x11 terminal for my rack-computers  :D

    Fortunately, it was already cold, with no sugar or honey in it, so letting it dry and then carefully brushing off any corrosion with acetone (didn't have IPA) worked.
    I previously mentioned in this thread that I got a Logitech K400+ wireless keyboard with a trackpad, and I'm now using it instead of the laptop keyboard.

    It looks like a couple of traces inside the keyboard went bad due to corrosion, since I lost entire groups of keys, not individual keys.  I did verify the FPC was undamaged, and its contacts untarnished, and re-seated the FPC a couple of times, so it is unlikely to be a connector failure.  Again, it wasn't an original module, but a cheap Chinese replacement.

    Coincidentally, I do have a Amlogic S905X3 with 4GB of RAM (H96 Max X3 "TV box") I got from Banggood during the big sales, and now have a good reason to adapt for my ordinary tea-time computing needs.  (I.e., Youtube videos and discussion boards, with a separate IPS-paneled display (no touch) and this here Logitech K400+ keyboard as the controller.)

    That's the same problem I have with an home-made PDA.

    It's a personal project, so it's more like a prototype than a real product (very fragile), I need to design and to *somehow* print a "silicon bumper".

    The LCD is a 7" piece of glass, if the PDA falls ... it breaks. The chassis is a 3D printed PLA body, if the PDA falls from the table, it breaks.

    My phone can falls from the table without any damage. How is it possible? Well, it's a "rugged smartphone" designed to survive mountain climbing. It can't survive a skyscraper fall, but it can survive up to 10 meters fall, and it's also water proof up to 20 meters.

    "Rug-Gears" are waterproof and resistant to heat, chemicals, pressure, impact and more, mine should also survive a winter in Siberia, up to -50 C (I need to test this  :o :o :o )

    Do we need rugged laptops? Probably yes, but ...

    A simple XiMi Note 9 Pro costs 180 Euro (Android v10-based)
    A Rug-Gear with similar features costs 450 Euro, more than a Motorola E100 (310 Euro)

    about { CPU, LCD, RAM, battery, features }: Motorola E100 >> XiMi Note 9 Pro


    Rug-Gears: good, nice to have, but more expensive!

    It is probably running in powersave mode, even when plugged into mains. My partner's Thinkpad took to being slow (like running the CPU at 700MHz), fixed by replacing the battery. It seems that the system relies on only the battery power level to determine how long it's going to last (and, hence, when to switch to battery saving mode) and ignores whether external power is applied.

    A Ludlum model 3 geiger counter with pancake probe, the "Fluke" of geiger counters!

    and a Spellman 10kV 3mA PSU!

    look at this interesting design, an RF air core transformer steps up voltage and rectifies it through two diodes, but the whole transformer secondary module is flippable to swap polarity.

    A boat load of 3M 9105 N95 respirators arrived from Mouser of all places. They're unfortunately out of stock but you can back order them, they bloody sold out within a day or two of placing my order. Lead time is a year but hopefully it ends up being a lot less and I placed a back order just to see what happens.  :'(

    The omicron wave is ripping through Sydney at the moment and it's so frustrating trying to find decent masks locally at a sane price. Anything N95 or P2 (our rough equivalent) is somewhere in the $2-$4 range. I might have to resort to buying KF94's from Korea at this point (can get some masks for $1 each or less even after DHL shipping).

    I highly recommend the 3M 9105 if they fit you of course. They are "duckbill" style so while they look goofy the breathing resistance is very low. For some strange reason I thought a more protective mask would be difficult to breathe in and uncomfortable compared to a basic cloth/surgical mask, but that is not the case at all.

    This is so bizarre...I think mask buying/research has become a new practical mini hobby of mine ahahahah. Many of my friends and family work in hospitality/retail so I feel like it's my duty to kit them out.

    RE: best face mask.. I thought you were talking about this kind. I have a personal health issue that ensures that I am acutely aware of the filtration efficacy of face masks. I find many brands and types of masks are useless. Not these, Kimberly Clark ones, though. They work well. They seal out particulates There are several different styles, the ones I buy are shaped like a trapezoidal horse feed bag with elastic on each side, and fit over your face similarly to a duck bill.  Mold makes me sick and unless I use a mask that seals well I get really ill. So I know.

    Really big difference.

    Photo shows the result of a late purchase from RS on Xmas eve.

    [attach=1]

    RS were magic - can't remember the time but it was late in the day, but nevertheless I shortly got an email saying it had shipped! Better, I then got an email from DHL saying they had it, and it was progressing. Tuesday I got an email from them saying it would be delivered the next day and would need signing for, so rather than a late breadkfast commensurate with the season, I made sure I was up super-early to receive it. Late in the day I go another email saying it couldn't be delivered that day but they would deliver the next working day. So, again, instead of a comfy quilt I'm up at the break of dawn (OK, maybe 9am) waiting. And waiting. And waiting. Go to their track & trace and the parcel is at a 'sortation facility' still, but will be delivered next working day. Tried to phone them but, not being their customer, all they provide is recorded or computer generated messages.

    Figured they've probably lost it so got back to RS who were, again, excellent and returned an email to me within minutes to say they'd got in touch with DHL and the reason it hadn't turned up was because DHL were closed until next week! WTF?!? Why the hell didn't they say that instead of pretending someone is going to want a signature and have me sitting around waiting for them! Bastards. Needless to say, moments after the RS email I got a notification from DHL that the parcel would be delivered on Tuesday (yes, a full 11 days after shipping), and a check of the tracking shows it's now moved from 'sortation facility' to 'in transit', so I suspect RS may have made known their displeasure.

    I realise it's not the right time of year for parcels but if they'd just said they were closed I would have shrugged and got on with things, but instead they knowingly lied and led me on.

    I received the replacement HP EliteBook 840 G4 keyboard with Swedish/Finnish layout a couple of days ago.

    Herein lies the tale.

    The proper HP part is 836308-B71: Backlit keyboard assembly.  However, since it costs 120€, and I rarely use the keyboard backlight at all, and this is already a few years old, I opted to go for the cheaper, non-backlit assembly 836307-B71 instead, which costs 64€.  Yes, indeed: the backlight LEDs cost 60 euros.  Otherwise the keyboards are identical, including the pointing stick ("nipple") between G, H, and B keys.

    Well, I cannot really begrudge HP for the price: at least they have these spares in stock, and the price for the non-backlit one is very reasonable (considering how few Swe/Fin layout ones are in use, compared to e.g. US, DE, FR, UK, and so on.  Although the price for the backlit one is high, it isn't outrageous.  HP also shipped it very, very quickly: from my order very early on the 27th, it was already here in Finland the next day at nine in the morning.

    UPS, of course, completely botched the tracking.  It first stated that it would be delivered by the end of the day on the 28th, and when the day changed, it turned into "we'll let you know".

    On the 29th, UPS still had no idea when it would be delivered ("We'll let you know when we know the delivery date"), so I had a epiphany:  I wrote a grocery list, almost put my coat on to go to get my new years groceries, but instead just sat down waiting.  It only took fifteen minutes for the UPS guy to knock on my door, with my keyboard in hand!

    (I know that sounds unlikely, but it is true.  It took me a couple of days to believe it worked.  No, I am not prone to magical thinking or superstition; it was just too perfect an experiment.  I just didn't believe it would work.  Probably should have bought a lotto ticket?)

    The keyboard seems to work perfectly.  There might be some tab differences between the 836807-D71 (non-backlit) and 836808-D71 (backlit), in the lower left corner, as I now see one of the tabs is not seated correctly.  Not a big deal to fix, which I'll do right now. Edited: Nope, the two match perfectly, it was just dirt blocking the tab slot on the plastic chassis; so, the only difference between the two is 836807-D71 does not have the center FPC cable for the LED backlight.  Functionally, no complaints.

    Been wanting one of these for a long time - but only intermittently...when I need to see in the dark :) Then, it would be off to find some flashlights and get them held or positioned....and so on and so forth. So, for $40, I pulled the trigger.

    This model, the " ePOWER 360 Rechargeable LED Worklight & Spotlight" from Casa Costco is not a new model and there are several GooTube videos and various reviews around. It looked like it fit the bill. I charged it up and did some testing and I still feel like it fits the bill - so maybe it does :)

    some CD4040 IC's, sockets, toggle switches, pin-and-barrel DC plugs (Lumberg, reputed to be least worst) and a big honkin' 230/12V transformer, to drive the stomp box PSU circuit I've stripboarded together. Soon, any year now, I'll get to be building a chorus pedal with the Middle Boy.   Separately, from the Pearl River delta, I've ordered cheesy Ø 45mm analog V and A meters to go on the PSU box.

    Youngest Boy has a IBM Model M usb mod cable coming, as part of his Model M refurb project.

    Kitchen exhaust fan is getting a 0-1-2-3 cam switch (Nockenschalter), also from the Pearl River delta, because the original one burned out a year ago. I'm tired of my hot-wire of "Max Speed" to a 0-1 switch, and I want the lights to go on with other kitchen lights.

    Needed some basic speakers for computer use so I would get a break from wearing earphones/headphones all day. I settled on the Fostex PM0.5dB studio monitors, somehow they are quite good value here down under at 300 dollarydoos (USD220) shipped for the pair.

    Although it's slightly overkill for my needs, I wanted something more future proof that can handle simple home theatre hand-me-down duty (would be way better than using built in TV speakers). Otherwise I would have gone for something smaller for better fit on the desk.

    Ironically it will probably spend most of its time playing lofi beats as background music. Oh well, you can take me out of the audiophile forums but you can't take the audiophile out of me ahahah. They were a bloody uncontrolled mess without EQ in my tiny untreated room/setup.  :P

    Is that a triax connector I see on the "I input"? If so, welcome to the triax club. It's an exclusive club for those with a little bit of money to spend on test equipment connectors and cables....

    Scored myself a nice HP 4140B on Ebay, $290 delivered.  The last cal sticker is mid 2016.  Both voltage sources check out accurate against my K 6500 as well as their respective current limit functions.  Offsets on all ranges are in the range of +/- .003.  With a very rudimentary high resistance setup I was able to confirm current measurement functions.  Now I need proper fixtures and cables and will officially have my toe in volt nut waters.


    Is that a triax connector I see on the "I input"? If so, welcome to the triax club. It's an exclusive club for those with a little bit of money to spend on test equipment connectors and cables....

    N.B. that there are various different triax connector standards and watch out for connectors/cables that connect various contacts together.  Both are traps for the young players.

    Yep, 3 slot triax. I had no idea how expensive those are, but I have a few do dads on the way. I almost fell into the 3 (very expensive) vs 2 (somewhat expensive) slot trap.

    Got one of those novelty component testers from AliEx after 2 failed Amazon attempts. $10 cheaper too.
    Can they measure FET pinch-off voltage?

    Mine just seems to measure Vgs (gate threshold voltage) but not pinch off.
    It's a basic tester and component identifier. It's limited by the fact that the test voltages are less than 5V (Except for the zener test which is 30V max) and the currents are low. (5ma or so)

    A Tektronix 7A22 and a 7A13. Both sold as spares but after first check out working. The 7A22 has some crackling switches but the 7A13 seems completely fine. Ten minutes after testing the new plugins one of the 7A18's let out the magic smoke - a short on the 5V rail fried a small choke. Oh well, you win some, you lose some  ::).

    Gotta find that fault now, at least the mainframe is fine.

    That is where a thermal camera would shine. Power the bus with a current limiting power supply like 1V 200-500mA (start with less) and look at the board. The dead part will heat up and you will see it.

    That's what I call "Lazy diagnosis" and is also what I regularly do! :) But most of my repairs are 80's digital (TTL) devices with endless rows of 74 series IC's. A Thermal camera is your best friend in those situations.

    RCA RB-10

    Used at start  wwii by SOE 170 were shipped out from USA >>SOE<<French Résistance before the "spy sets" were deployed.

     My Grandfather had a similar Emerson, I recall from 1952

    Anyone else have these old tube portable sets?

    Bonjour

    Worked  telephone interconnectand patents.

    Just recieved these 1970s Bell System Linemans set and tone tool like banana tracer.

    Linemen's set has talk/monitor and original cloth leads and clips.

      tracers  use 9V battery like an AA cell.

    All others use 9V transistor battery.

    Tone generators (square and rectangular yellow) generate a talk battery and have an early LED or alternating distinctive tones high low.

    Anyone else interested in vintage telephone tools or gear?

    Two HP 59306A HPIB controlled relay boxes. 1973 era design, these were built in 1979. Complete HPIB implemented in TTL, and on fully gold plated PCBs. No cost spared  :-+

    One of the boxes will house my homegrown RF power meter, the other one I left alone. Threw some Python scripts at it via the HPIB. Works fine. As a useful side effect from dismantling one: qty 18 HP binding posts  :-+

    An HP 8770A Arbitrary waveform synthesizer. See HP catalogs
      1986 pg 450  1st mention
      1992 pg 455  OPT H12  digital data output.
      1997         Last brief mention

    Relatively cheap ($160) due to dented front panel, broken off power button, and front status "error" light lit.

    I'd noticed in seller's pictures the two clock loop-back cables on the rear were absent, and hopefully that would be the reason for the "Fault" light.

    Fixing the bent panel and broken button switch both met difficulties. That's another story.

    Once done, with the loop cables in place now it powers up without the fault light. So hopefully it's working.

    Still need to set up some kind of HPIB control system, to run it. It seems to have had a few versions of software for wave generation, that ran on various platforms. Does anyone know anything about those?

    I aim to do a teardown. Especially since there _might_ be a screw and nut still loose somewhere in the machine, that had worked loose from the fan mounting. Missing, no apparent rattles in the case and hopefully they are gone. But it would be nice to be sure.

    This machine is another instance of a manual with schematics existing, but when you check it turns out that HP chose to omit schematics for one or more crucial boards. With the manual claiming along the lines 'Board not repairable, return to HP for replacement.'  Translated: "We just don't want to give out circuits for some boards, because secret."

    Grabbed another basket case off Ebay.  Kikusui PLZ 300 seen here after a thorough cleaning, repair and tune up. Now working perfectly.

    [attach=1]

    Other than the two digital voltmeter chips driving the displays it is entirely analog.  No keeper battery, no firmware to rev. and no digital interfacing.  The output signal is analog voltage, the display decimal points are comparator driven, switching frequency and PW is via 555s, and even the power calculation is performed by an analog multiplier chip.

    Its not the best, but it works. Maybe a 6/10. My main gripe with it is that there isn't much grip. If you don't have it held secure, turning it can be a challenge. The action itself seems fine though. Greasy hands? Forget it.

    For some, that could be a positive as there is no way you are going to bump it on in the bag though

    I got a whole lot of PTFE stuff: Rod and a spool of wire. Very nice for high voltage/impedance/vacuum stuff!

    Nice one. Check the RIFA capacitor which you'll find near the power socket at the back - its worth replacing it before it goes phut. I also replaced the fan on mine with a quieter Papst one.

    Although I always was a bit suspicious on the performance of desoldering irons since throwing a similar device against a wall out of sheer frustration twenty years ago, I must admit that this one seems to do the trick very neatly. Technology has moved on, it seems  :D

    Once you've use a good desoldering station, you'll never want to go back to a Solldapullt or equiv.
    Just make sure to clean the chambers and tips (Inside and out) regularly. Also change those flux fume filters every now and then or when it seems like it's losing suction.

    I bought a new [to me] HP 3312A.  I got it for a good price since it was sold "For Parts" because of missing knob caps and (blue) center push buttons.  I've since replaced the push buttons with a small length of wire insulation and a bit of Q-Tip stem as filler (the white part). 

    This beast is all analog; no MCU inside. I'm just amazed at how well-engineered it is. From the front-panel aesthetics and over-loaded yet intuitive controls, to the Lego-like case that's built like a tank, to its gold traced PCBs and laced wire everywhere.  It's vintage '82 and after 40 years, it still works (and smells) great. 

    I also picked-up two HP 59301As for a very good price.  Back in the day, they were used to make some all-analog HP test equipment GPIB-aware; ie. "programming".  Basically, you push a 16-byte string to it and the bits are placed onto two 50-pin Centronics-type (telecom) connectors as TTL; like the way we use GPIO pins on todays MCUs to interface to the analog world.

    I bought them for the case and 5V power supply.  I'll just substitute my own PCB and new front panel, and voilà, fits right in with my other test equipment!

    A few more HP Application Notes for my collection. Actually, more than doubling the collection size.
    This was an amazing deal. $1 each, from a guy that used to work at a USA HP office, and ended up with that office's entire AN stock when they closed.

    They came to Australia as three boxes, on one flight. And then... Australia Post 'lost' two of the boxes for over a month. They'd been put aside somewhere in an Oz Post facility near Sydney airport due to arriving in the pre-Christmas rush. And just forgotten.

    Finally arrived today.  It's going to take a while to update my list.

    You push the hollow needle to the circuit board hole and to the leg of the component you want to desolder, when the solder is wet. Like this:

    Klein LAN Scout Jr. 2

    I paid USD55 for a new one from the hardware store because I needed on to finish up a wiring project at home to keep from losing momentum. We have several Fluke cable testers at work, but it's a pain to drive in and then back to return it since I work from home now. I'm going to be doing more home wiring in the next few months, so I figured I'd get some more "value" out of it. It functions very well on NiMH batteries, BTW.

    https://www.kleintools.com/catalog/cable-testers/lan-scout-jr-2-cable-tester (https://www.kleintools.com/catalog/cable-testers/lan-scout-jr-2-cable-tester)

    After using it several times I will vouch that it does what it is advertised to do. Although there are few tests as good as running gigabit speed data with PoE over your CAT6 (or whatever), this tester is easy to stick in a pocket and use on top of a ladder / in the attic / etc.

    EDIT:

    Will it detect correctly polarised but wrongly paired conductors? I.e. when you've swapped two conductors from different pairs the same way in both ends? A DC test will not hear it, you'd need an AC cross-talk test..

    No, it only detects that this here wire is connected to this here wire. Doesn't even have a built-in TDR or anything.

    I recently bought some dodgy counterfeit components from Ebay seller Adeleparts2010 for the following reasons:

    1. I really enjoy a challenge.   :bullshit:
    2. Formerly Farnell are formally fuckwits.   :o
    3. I went completely nuts and lost the plot.   ::)
    4. All of the above.   :wtf:

    To: Adeleparts2010,

    I recently purchased and paid for items listed on your Ebay store which were described as:
    “5 pair SANKEN 2SB1560/2SD2390 B1560/D2390 TO-3P”. The listing included images which I believe represented genuine Sanken components yet the items I have received are not genuine Sanken components and do not conform to the both the physical and electrical characteristics as described in the Sanken technical specifications. As an experienced electronics technician I am quite confident that you have sent me fake or counterfeit products, you have misrepresented the Ebay listing and wasted both my time and money.

    I included a message during the purchase process which stated the following:
    “Hello adeleparts2010, I would very much appreciate if you are able to supply me with brand new and genuine components, please do not send anything other than as your Ebay listing describes. This order is for 5 pair of good quality and brand new SANKEN 2SB1560/2SD2390 B1560/D2390 TO-3P. Kind regards and many thanks.”

    You have clearly ignored my request for the supply of genuine components and instead sent me poorly copied counterfeit products. I hereby notify that it is my intention to pursue this matter by lodging a formal complaint to both Ebay and Paypal in relation to your questionable practices.

     :-BROKE

    Recently bought a 80v Greenworks electric shovel  and also chainsaw.

    https://greenworkstools.ca/collections/80v/products/80v-18-chainsaw-2ah-battery

    I have a 18v Ryobi Chainsaw but figured I will need something a bit beefier on my homestead property when I start clearing trees this summer, and the snow shovel is a nice backup to the snow blower. 

    I've actually been quite impressed with the shovel.  So far I've manged to use only the shovel, and not the snow blower.  We have not had any serious snow fall since I bought it though, only like 10cm here and there.  Since it only shoots forward it does require some manual shovelling so that you can start off pointing it in the right direction and get around any odd corners but over all it works well and I'm quite impressed.  I can do the whole driveway on a single charge.    I've also put it through some snow piles that are much larger than it's really made for.  If I hover it over the pile I can kind of skim it.  The main thing is that it saves the work of having to shoot the snow into the yard.  So even if I do lot of manual shovelling first so I can even use it, it still saves a lot of work and time.  For when we only get a few cm of snow I'll just shovel the snow into a pile then use the electric shovel to shoot it out of the driveway.  Makes for a very quick job.

    Also used it to get the snow out of the box of the truck.  Way faster than doing it by hand.

    Have not used the chainsaw yet though.  I have a giant log in my garage from a tree I cut, so I may test it out on that and cut it into small slabs to use as some kind of crafts project or something.  Maybe a clock for the shop.

    Electric stuff has come a long way in the past few years.   There's even a few companies selling full size electric snow blowers now.   Greenworks has snow throwers which are kind of a between, so I kind of hope they do come up with a full size snow blower too at some point so I can use the same batteries.

    How do you like the "snow shovel"? We got what looks like the identical unit - except the 120 volt corded model.. and so far I am not at all impressed. We've only had one tiny snowfall this year that justified bringing it out and bluntly, it seemed anemic. There was maybe five inches of snow and it could not be pushed forward into that little snow without stalling on it. Around the width of my hand, almost no snow, depth wise. Just enough to completely cover the grass.. and look pretty, and show what a piece of crap the electric "snow shovel" was..

    I videoed it struggling, if you want to see it. Maybe there will be more snow, I hope not. Sometimes we get clobbered with snow and for times like that it would be nice to have a real snowblower. One that could hurl the snow off of our driveway with some force. But that was not to be with "Greenworks"

    We had previously gotten one of their electric lawn mowers and we like it. Its quick and seems to have the power thats called for.. which isnt much here in our grass-farming subdivision.   So, great.

    My wife had gotten it, for around $85 as a refurb and after its humiliation by the smallest storm of the year I wanted her to send it back. It really deserved to be sent back.

    But I think the time to send it back had expired, so I think we're stuck with it. Ouch!  Maybe there is some aspect of it I'm missing. But I kind of doubt it. Let me know if you like it. Being well north of me, you'll probably get more snow than I to try it out on.

    I have had a black and decker electric chainsaw for years and it works great. The most important thing with it is to keep it well lubricated wit the recommended oil. It needs to constantly be lubricating itself. Using the electric chainsaw, I have cut down and chopped into manageable pieces several small and medium sized trees, and saved us many times its price by buying it. So, definitely happy with it. I like the idea of electric tools, far less trouble than the typical two cycle engines used in lawn and yard power tools. But sometimes, you just need that power.. like with the snow shovel? Maybe. I guess we'll see nexttime.

    Let me know how you experience with the battery shovel goes. I think we have one almost exactly like yours, except ours plugs into the mains power. (It has a fused plug)

    Bought Power Design 2005A already in Germany already converted to 230V
    What is done for rework on 220V

    You just swap two leads to get the two transformer windings in series instead of a parallel configuration. Procedure is explained in the manual, did it for my 2020 and it took less than five minutes.

    A bunch of the PD models did not have that option; and the 2005, IIRC, is one of them.

    Looking at the service manual (http://manuals.repeater-builder.com/te-files/POWER%20DESIGNS/POWER%20DESIGNS%202005A%20Technical%20Data.pdf), this looks to be the case. Only one primary winding, and no mention of reconfigurable mains supply in the text.

    I was -><- this close to buying that specimen, but I analysed my needs vs funds and concluded that I have other more pressing needs. Like fixing the Oltronix 3-voltage PSU that does not deliver anything above -0,5V on two outputs, for instance.

    A company called Fieldcrest in the UK makes LC plastic sheeting material that costs very liittle that works as well or better for detecting shorts that generate heat. Everybody should own some..

    That is where a thermal camera would shine. Power the bus with a current limiting power supply like 1V 200-500mA (start with less) and look at the board. The dead part will heat up and you will see it.

    ^ I much prefer the AM503B. The AM503 has way too many contacts and stuff in the range selector. The AM503B makes the range selection 'digital' and I've found over the years that it is rock solid in performance. The B also has better degauss/auto zero capability and a few other enhancements. Anyhow, good luck.

    Thank you for posting this. I've got some on order.

    Were you able to track down a datasheet on the VTX0225AR?

    I searched for VTX0225AR and VTXO225AR without any luck. Nothing on Rakon's site and no reply from them either.

    I can't help but wonder if the clipped output can't be bypassed. I'll scope the thing when I receive it. It could be as simple as crushing a couple of smd components.

    Needs some feet and a minor repair of one of its channels since it cannot hear anything below -20dB on that one :-/O. Thankfully I've got some accessory cards with the unit or I would be shit out of luck should its internal non standard drive die. The analog output plotter card also gives me the excuse to buy a pen plotter for it to draw nice graphs :D.

    I probably made a mistake and bought a smartphone. AT&T is cutting off 3G here tomorrow and of course I waited till the last minute to buy a new phone. I went to two different AT&T stores with no luck (we only sell contracts) (sorry they're all out of stock), then they finally found me a cheap one at an odd place called "Fashion Plaza" where they specialize in flamboyant, urban clothing with a cell phone sideline. They told me I could probably get a cheaper "dumb phone" at Walmart, but I really don't like Walmart much. At least I have something to make and take calls and it'll have do for now.

Already have a power supply and I will Laser cut a case for it again like I did for an earlier 2400G. 3200 CL14 memory was about the best balance of $/performance for what I need.

    Barbell clamp.

    Not for weight training but as a replacement for the locking collar on my microscope stand. The photo shows the principle, although the real thing would usually have a horizontal bar rather than the head holder being directly mounted. In both cases there is a screw to tighten which locks the fitting to the vertical bar. But then the horizontal part can't swing left or right. So, instead, a collar is fixed to the vertical bar and the horizontal part just sits on that, allowing the head to swing nicely.

    Usually this locking collar is fixed or life, but I find the range of adjustment of the head focusing knob is just too small to cope with the full range of PCB holders and stuff. So I often move the locking collar, or think I should be just can't be arsed because it takes three hands: one to hold the head, one to undo the screw and the other to move the collar. This barbell clamp makes it dead easy to adjust the height.

    Nice score!  Frustrating how it often seems like it costs more to get something to store the parts in than it does to get the parts, and that unless you pay stupid $$ the storage that is available is crap.

    I've been slowly buying various plastic storage boxes from McMaster-Carr over time - they're really nice and I like them for storing bits and pieces, but at typically between $15-20 a pop they add up fast!

    So excited *** so excited *** for my new WR Monza Speed Road Bike (second hand)
    [attachimg=1]

    Just arrived and mounted, it comes here with an imported carbon frame, which I don't like too much because I prefer aluminum frames (cheaper) but the whole bike is really light, only 6Kg for the whole bike compared to my my old bike that weighs 11Kg.

    That sounds a dream!!! only 6Kg is really WOW!

    since the carbon frame and two endurance-wheels cost me most of the budget, the gearbox I mounted is economic for its category and it is full manual, as well as hydraulic disc brakes. I don't care. They are decent enough!

    This bike was not designed for endurance, it was for high speed racing, so I changed the saddle and handlebar attachment to make it more comfortable.

    Only 1200 Euro for it shipped, including all the replacement parts (second hand, but in great shape) I ordered separately, it sounds a *** great bargain ***, and I also love the color.

    With this setup it for sure less aerodynamic, and you lose the 10% during acceleration, but I don't care too much  :D

    Looks great. Changing the saddle and (presumably) raising the handlebar is a smart choice. I don't think the performance gain is worth the injury/strain risk, unless its only for races.

    eh, it was the *only* part not included in the deal, so yesterday I went to a shop to buy them because pedals from my old bike are not compatible

    Fillet with a different pitch, don't ask my why. Crazy stuff.   ;D

    Yesterday I enjoyed my first 90 Km round trip, but it was rather a kind of running in since I don't yet know how my bicycle reacts, and it's really fast, even faster than I imagined.

    I even overtook a moped, 60Km/h or something, and when the traffic light gone yellow I was a bit worried about brakes because it rained in the afternoon and there was a little puddle.

    Kind of strong emotion during a Kind of test, braking on a wet street and decelerating from 60 to 10Km/h

    Hey, ok? Both brakes and tires worked :D

    Clip Studio Paint for ~USD30 (40% off right now for the next few days). As a complete beginner to art I just didn't have it in me to go deep into the Adobe Cloud subscription crap, so having a perpetual license for CSP takes the stress out of worrying about a subscription I may or may not use to the fullest.

    Recent wet weather in Sydney took out the garage air con PCB, I think there was a bug or something under the transistor...blew the breaker when I switched it on. A replacement PCB was AUD200 on eBay, not great not terrible. At least I'll have a donor board I may be able to fix up for the future.

    The rain also made its way into our solar inverter, it's around 10 years old now so it's had a good run. The transparent display window just disintegrated over time and the rain went right on in (I used to tape over the window but it kinda fell off). Hmmmm thinking of spending the extra and getting a Fronius or similar so I don't have to worry about it for the next 10 years under warranty (until the panels poop out). The solar feed-in rate is crappy compared to when we first got it so I don't think I'll be upgrading the 3.5KW system.

    Plasma cutters do like air!  And circular logic is, in my opinion, a perfectly valid means of justifying the acquisition of tools and the like.  Buy a piece of test gear, read the manual, see what they call out for 'recommended test gear' for troubleshooting and repair, buy any of those instruments that you lack, read their manuals, see the 'recommended test gear' sections thereof, buy...   ...lather, rinse, repeat until money or space run out...

    The postman brought my nice Katsu mini drill press today.

    So far, I'm favourably impressed. I'm sure the simple triac based variable speed motor controller can be improved, but it's a surprisingly solid machine. The oversized base is cast iron and the head, cast alloy. In addition to the variable speed, there's a 3 step pulley change allowing it to get up to 8500rpm - An ideal companion for my big Sealey pillar drill when using small drill bits. Something I was worrying about when I ordered it was accuracy, but I can't detect any slack at all between the quill and the head casting and there's no noticeable runout on the little 6mm chuck. No flex between the head and the base either.

    The wiring looks ok. It's properly earthed and there are decent insulated crimps and additional fibreglass sleeving where the wires pass the motor. I might put some additional strain relief on the motor wiring though as the motor and pulleys go up and down with the quill.

    Overall, really chunky for such a small capacity drill press. The motor is only a 100W brushed, but that ought to be sufficient for small diameter drills - maybe I'll experiment with a brushless one at some point as there's plenty of room.


    P.S. The adjustable quill stop seems a bit odd - I think they've put the scale sticker on in the wrong position!

    Oi, get your own, this ones mine ;D

    The fun with running these off an inverter is that the fast/slow control is done by switching the motor from two to four pole operation by means of an interlocked contactor, and this can be done while the motor is running... Most inverters get upset by that kind of thing.

    Also, selenium rectifier stacks for the carriage drive motor, yea those can fuck right off, easy fix obviously. Interestingly the carriage drive motor does field weakening for high speed mode, not something you expect to see.

    I casually put into operation 2 links of 4x25Gbit/s capacity today. (4 wavelengths in one fiber, 1295.56, 1300.05, 1304.59 and 1309.14 nm, adding up to 100Gbit/s, 100GBASE-LR4, IEEE802.3ba-2010)

    1.25 Gbit is impressive, and more than most people would need for many different purposes, but high-speed it is not, not anymore. (I run singlemode 10Gbit links at home, so it is common.)

    Granted, a coherent 100G system, that is something extra. Not for the faint of heart. 4x25G is much easier.

    Meh, got switches in the home office that do that, sort of need them when messing around with ST2110 routing and trying to get the shitshow that results from letting web 'programmers' come up with an interoperability standard for real time doings to actually work properly.

    Granted, I am not doing the WDM dance.

    Saturating a 100Gb link into a switcher or multiviewer is disturbingly easy with a reasonable number of 4k60 4:4:4 feeds.

    I've had one of these for a while.  Works great for PCBs and 1mm drill bits, lacks torque for the larger stuff >5mm.  I've snapped a couple of belts over the years though, but they're pretty easy to find.  Bought mine from Warren Buffet (riogrande.com)

    Yea, I am NOT a fan of NMOS (Which does NOT refer to the old logic family with no noise margin).

    I sort of look at NMOS and wonder if it isn't the last glimpse of interoperability before the proprietary solution monster eats us all.

    The big problem with the business is that it is driven by vendors who have no clue in the Internet standard development model, who are trying to sell complex interdependent networks (more complex than they comprehend) to people who have no idea at all about networks, and are used to paying way too much for special hardware, when all of this, today, can be done on mostly standard gear...

    I've got Nevion "control" (the guys who do not believe in multicast routing protocols), and there's LAWO "control" (the solution that can't even control all of their own gear nor interoperate with their own control system) around the corner. I am not impressed with either. And none of them have left the mind model where a facility is only so large as the reach of a piece of Belden coax with blackburst on. ST 2022-7 is completely, utterly incompatible with anything except one studio facility. I've got 4, in a square, with a diagonal added in of several hundred kilometers of wonderful 100G links in between. How do I map this to a very dumb A/B redundancy model?

    Lawo is a funny one, I mean Ember+ is basically what happens when you give a German SNMP and tell them to make something almost, but not completely, completely unlike this.... They could SO easily have grafted on a few extensions for discoverability and realtime data and it would have just worked, but no, have you SEEN that spec? It has wonders in it, like the fact that the 'oids' are NOT required to be consistent from one run to the next, it is the text strings you have to match on.... <Spit>. And then you get VSM, classic consultantware.

    Trouble is, with GV clearly doing the pivot into being a software company with cloudish aspirations, that don't leave a whole lot of choices, BNCS maybe?

    The thing that narks me about the whole NMOS thing is that absolutely NO consideration appears to have gone into doing little things like plugging an IP truck into an IP facility over IP.... You pretty much CANNOT do it without a LOT of forward planning on both ends, and this even applies when using trucks from a few different vendors on one job, it is all SDI and MADI between the islands of IP.

    Actually, we've got a buncha people who actually grok VSM. We did the entire "decouple control room from studio" automation, the thing that people usually "go to IP" for today (which means a big chassis switch and lots of converters  :-DD ) on SDI 12 years ago. With VSM as the motor.

You pretty much CANNOT do it without a LOT of forward planning on both ends, and this even applies when using trucks from a few different vendors on one job, it is all SDI and MADI between the islands of IP.
     
    </rant>

    Yes, it's a quagmire. I wish that broadcast vendors learned to shut up and not try to build a kingdom that requires perfect obedience in every detail, and then try delivering that turn-key. It never worked before, not even when all was BNC and XLR. I want building blocks (like "audio mixing"  or  "audio source",  "camera signal", etc with good, publicised, standardised interfaces.  Then I want to require them all to tell me they're there, and how to control them. And that they tell that to something that they find using a modern provisioning system, not a decades-old hard-coded address.

    And, if they say "mdns", I will get right violent.

    With the connect two trucks scenario, it's basically the same as "let's try and merger two companies who both use Net 10" -- which I've tried.  The broadcast world seems hell-bent on reinventing every mistake the corporate net world has made the last 30 years, only with more bandwidth.

    MDNS? Yea, that was AMWA/NMOS wanting to do the existing tools thing, completely unsuitable IMHO for this kind of scale (Especially the way NMOS does it).

    Mind you AES dropped the ball as well with not putting the minimal amount of metadata needed to successfully decode an AES67 flow into the flow itself... Grumble.

    There does seem to be a LOT of reinventing the cockup going around, the control systems are grossly unsuitable (They think in terms of routers still, not controlling endpoints and trunking), the customers don't understand the technology, the standards folks mostly don't understand broadcast, and the SIs are doing their usual trick of over promising and then blaming the vendors. 

    I loved that there really does not seem to be a way to build an NMOS configuration in advance of having all the kit on site and connected to the registration server, I mean being able to build the config back at the office before getting to that expensive time on site would make all this shit way too easy would it not?

    While SDI had its issues, god knows, SWP08, Quartz and TSL UMD got you control of basically everything, would that the new world was as easy.

    I remember having a few discussions with people involved in the AES67 group about how Certain Vendors didn't want things to be too easy. And, as I'd by then built a complete SIP-based registration system (kicking EBU into issuing an updated Tech 3326 in the process) for remote participants, I kinda thought it would work out any way. And, it actually does. But it is very much implementation specific, because someone (I guess both the "Let's run PTP1" people down under and the Italian Town gang) wanted their little walled gardens unthreatened.

    Basically yes. People want "make TV" look and feel the way they did experience in the 70s, and nothing to change. The "I want a box to be playing the role of router" paradigm is the most annoying part. The network is the router. It is a if not country- so at least site-wide (mostly) non-blocking matrix.  People can be made to understand it, but you have to repeat it over and over.

    Amusing to see the PTP V1 Aussie gang and the Italian town gang agree on anything.
    Doubly so when you note where the person the PTP V1 gangs main product is named after died...

    I despise standards committee bullshit like that, just makes everyone's lives harder.

    Still could be worse, SMPTE managed to come up with a PTP profile that actually breaks some standard PTP receive code! The facepalming was allegedly epic. Course the Canadian cousins (Burlington Ontario branch) then went and implemented what SMPTE had cooked up instead of IEEE1588, not that interop was ever much their thing...

    Still think SMPTE taking a whole pile of FREE IETF standards, packaging them up with very little additional text and then selling the bloody things was cheeky.

    I've been trying it out and it's pretty cool, but one of my big usages makes it quite annoying. What's the best route to finding if it's just a config option I've missed or if it can be otherwise sorted?

    Specifically, a session starts with the size of the terminal tab. Suppose I use RDP to access some remote machine - I set the session to have a detached tab (it wants to be a free-standing window) and that detached tab is the same size as the current main terminal tab. If I change the size manually, it's never remembered but always starts with the current terminal tab dimensions (this is one of the huge issues with using a browser as an app).

    This matters to me because that RDP window will be, say, 1024x768 but another RDP window will want to be, say, 800x600. I've tried fitting to window (just makes the remote the wrong size), smart sizing (just distorts the view), etc. I am tired of having to spend time dragging window corners to get rid of scroll bars.

    Further, why should a GUI window want the same dimensions as a text console? And this doesn't even broach the issue of being afraid to resize the main app window because it will affect every session started from then on!

    I must be missing a simple option along the lines of "save per-session window size" but I can't find it. If I could I'd spring for a license, no problem :)

    Just received 2 pairs of optical transceivers today to experiment with high-speed optical links.
    (Those are bidirectional 1.25Gbps 1x9 transceivers.)

    I casually put into operation 2 links of 4x25Gbit/s capacity today. (4 wavelengths in one fiber, 1295.56, 1300.05, 1304.59 and 1309.14 nm, adding up to 100Gbit/s, 100GBASE-LR4, IEEE802.3ba-2010)

    1.25 Gbit is impressive, and more than most people would need for many different purposes, but high-speed it is not, not anymore. (I run singlemode 10Gbit links at home, so it is common.)

    Granted, a coherent 100G system, that is something extra. Not for the faint of heart. 4x25G is much easier.

    1 Gbsps is indeed considered "high-speed communication" in the digital design context these days. Just a technical term. I thought we were on some electronics forum, not Twitter. ;D

    As the word 'experiment' and the bare transceivers suggested, my intent is to design my own links, using FPGA and stuff. Prototype stuff. "Advanced" DIY. Not using existing networks and switches.
    While doing that for 1 Gsps is already challenging, it's doable. But I dare you to do that kind of thing with 25 Gbps or higher. This is certainly nothing "casual" ( :-DD ), unless you are just using off-the-shelf equipment, which I thought was clearly not the case here, but if it wasn't clear, now it should be. =)

    To be very explicit, it was the orders-of-magnitude dissonance between what is being casually used and what was described as high speed that bothered me enough to dare writing this. I fully appreciate and admire the challenge of doing it as "advanced DIY", but I felt that the mountain of giants standing on giants that the modern comms industry has built for itself to be able to reach present levels of performance could do with some pointing out.

    Simply because we take it for granted.

    Bought qty=4 Brymen BM857 multi-meters and one optical link cable. I got -20% off, free bags and free shipping.

    Arrived yesterday, looks the best deal ever ;D

    Three units are for my friends, one multi-meter is for me.

    I know there is Sigrok support, but I am going to write my own application for Linux.

    The serial communication is not complex, I have already downloaded the documentation about the protocol, and it's all textual presentation of measurement values, floating point, normalized mantissa plus exponent, combined with binary bit fields for current meter's function and measured unit.

    So, kind of variable length records with control chars in the header and footer around the mode flags and value's text, and up to 22 bytes per serial packet.

    Just be absolutely sure to watch for the moisture on the floor if you are installing it directly in the concrete foundation. In our previous house we suffered with infiltration from the concrete slab that not only ruined the floor after some 10 years but also added a lot of mold to our house. If you have a basement, then it shouldn't be a problem.

    Marconi 2024 9kHz-2.4GHz signal generator, arrived this morning, fixed in 30mins by replaced a capacitor in the power supply. I have to do some cleaning later ;D

    After about 6 years, this unit failed again! There is no response after pressing the power button, it seems that the SMPS is broken again.

    I opened the case and measured and all the rails had no output, so I took the power module out to check and didn't see or smell anything wrong. However, just when I tried to flip it over in order to inspect the bottom side of the PCB, I was shocked badly.  :scared:

    My ring finger hurts so much! Yes I know that the capacitor must be discharged before repairing the switching mode power supply, but I clearly saw that there are two discharge resistors on the PCB, and this electric shock should not happen! I checked the 4 capacitors (2S2P) next to the rectifier bridge with a multimeter, two of them measured 250V and the other two measured 0V, so I found a suitable resistor to discharge those two dangerous capacitors.

    Then I removed the two discharge resistors from the PCB for measurement. One of the resistance values ​​was a normal 100K, and the other was measured as an open circuit.

    I found two 150K resistors, they are a bit big in size, but still fit into place on the PCB, after soldering them I put the power module back in the case, connect all the cables, press the power switch down, and it works!

    This is also where I am confused, the only explanation I can think of is that the two discharge resistors are also used to prevent uneven voltage drops across the two electrolytic capacitors in series.

    Yep by far the safest implementation in SMPS is for the controller to continue running until the charge in the HV caps are depleted to safe levels where under voltage lockout engages and stops operation in a safe state.

     :-+

    Here in Sweden, the building code says that the slab shall be free of capillary humidity transmission from the ground; so under the cast concrete there shall be a layer of coarse gravel without sand, or an insulating layer of expanded cell foam or both. The slab shall be dry in all circumstances. Then, inside the insulation, so there is no condensation-triggering  temperature gradient, a special aging resistant plastic film is required, with its accompanying tape. Very sticky.  Done right, with enough ventilation, it's nearly foolproof.  A challenge is to keep enough ventilation in these constructions, since there is a tendency to minimise draught for energy efficiency reasons. (we're on 60° North, so it gets cold in winter.)  I rather freeze than get sick from mold spores.

    What happens here is the home owner often builds up dirt outside for garden beds, sometimes even higher than the inside floor level. Where I am we've had a stupid amount of continuous rain and the rising damp is causing all sorts of problems whereas in, I dunno, 4 years of extreme drought it hasn't mattered.

    Very similar in Finland, of course.  Mom's house is at 68°N, with the bottom floor underground, and never had any issues with the slab – actually, both the floor and the walls of the bottom/underground floor are concrete.  Granted, there is very little soil, and the ground is sand with layers of gravel, with a few meter permafrost layer starting at about 3m depth, and very pure groundwater (filtered through all that sand!) at about 15m deep.  Construction-wise it has double-width (100mm) expanded foam (EPS, brand name styrox) all around, and as a trick to deal with meltwater, underground "fins" of expanded foam sloping outwards at about 1m ground depth, to about 2m out from the house.  There are also underground drainpipes all around the house, of course, leading outwards.  40 years later, still zero mold issues, and the amount of meltwater each year easily compares to a flood.  Erosion in home road is a problem; that does needs fixing every few years.

    I can imagine how difficult it is to achieve the same with a thicker soild and/or clay-based ground.

    If you have a query regarding your health, speak to your doctor. This is not the place to discuss unapproved medical treatments or risky practices involving self-medication.

    Garmin Edge 830 bundle(1)  Cycling GPS computer, for my road-bicycle  ;D

    it costs 500 euro, I got it with 40% discount because it's not exactly "brand new" but rather some kind of stuff that sports centers have in their windows.

    The screen has no scratches, but a lot of fingerprints, and it doesn't look clean but a little dirty, but that's nothing you can remove with a gentle polishing tool.

    It's functionally equal to the Garmin Edge 530, but it adds touchscreen and better navigation menus. Unfortunately it messes the mounting bracket for the bike handlebar, so I bought one for 25 euro.

    I have some crazy plans for this summer  :o :o :o

    (1) for Garmin "bundle" meas with all the bio-sensors.

    I trust you are watching the Tour of Flanders then ;) My Lezvne GPS computer has plenty of sensors to tell me how slow I am going compared to the pro mob :-DD

    Added a Faked Makita 'brushless' impact driver to the kit today. Seems to actually be brushless with a few sockets and sub $30 USD equivalent delivered  :o Not expecting or needing a really heavy duty item and it will only see use 5-10 times a year so this is a bargain if it works ok. Reason to add it was I had to fuss around and go borrow a mates air one to install a Towbar with Taptite bolts and it was noisy and generally a PITA. eBay auction: #165035918581

    well, at least the Garmin can motivate you to train better, harder, faster.
    There is an integrated training program, it looks very useful and nice  :D

    @DiTBho

    You were smart to get a cycling computer, and not a watch.. (many I see being discounted, the reason I think is that they just dont work very well! and get returned..)

    There is a huge difference.. Mounted on a bike, the GPS has a good chance of being accurate.. I bet for your money you get a very nice package, with optimal placement of a good GPS antenna.

    In contrast, The problem with many GPS watches is the weakness of the antennas they use for them. I dont know how many here have done much analysis of the quality of the recorded positions captured by most "GPS" watches. The GPX (or whatever formats it saves) tracks can be simulated by putting a GPS antenna on its side and making your recording with it positioned like that. Or similar.

    Frankly, a GPS antenna has to be of acceptable quality (almost none are) and facing vertically (usually with very few exceptions) to be accurate.  I have a PND (personal navigation device) that contains an otherwise excellent Sirf Star III GPS chipset.  I often use it for this and when I am I have learned to make sure its GPS antenna is on its upward side. I put it in my backpack "CD pocket" which is at its top, and prop it up so the top is actually facing up and I get a good trace. If I dont do that (say it gets pushed down on its side) And I am in the city, almost without fail its horrible. This is I guess the problem with many GPS watches, phones when used for GPS, and so on. The recorded positions are crap. It gets worse in cities where streets are like canyons with only a thin strip of sky visible, straight up. The rest is mostly metal. Metal buildings.

    The only exception is the Sarantel quadrifilar helix antenna. It works no matter what direction is facing up!

    That is really true. Its one of the only examples of when marketing hype turns out to be true. Unfortunately, after I saw a bunch of these great antennas being discounted a year or two ago I was crestfallen to hear that they were going out of business.

    Frankly I am surprised the recordings are as good as they are, often times. If I was wearing a GPS watch I suspect the movement of my arms would find its way into the track also if I was running. Frankly the hands would be the worst place for a GPS on the body. I would try for a spot on the upper trunk or ideally, on a hat on the head. Or in a backpack attached to the back with straps. Facing up. That works well.

    This took a while. Back in Aug 2021 I bought some manuals in Chicago.

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1455097;image)

    Here they are in storage in the USA, after they were picked up by a friend. Yes, they are quite dirty, since the idiot seller had left them sitting in a garage for years with no dust cover while failing to sell them due to being incredibly difficult to deal with.

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1455109;image)

    And finally at my place. After quite a drama involving US West coast shipping.

    But... the shelf for them isn't ready yet. So not unpacking and starting to clean them yet. Well maybe just some little peeks...
    Btw, this is unrelated to the much larger manuals set I bought in Sacramento.

    That's why Garmin sells a kit to mount the fēnix 7X Sapphire Solar on the bike handlebar, or on the forearm with a band.

    Not only the GPS has less throttling, but also the Sapphire lens are better irradiated by the sun so the inside solar cell can make better use of solar energy.

    I can fabricate a hat-kit for the GPS-watch, or to sew something to use it in my backpack.

    No problem here, I can sew very well :D

    "Bought" (as in bribed my superior with munchies) an old HP 9000 310 computer system with seemingly full Documentation, HP2225 printer and keyboard from my employer's trash pile in the basement. Also some miscellaneous TE. Computer and Monitor work, HDD and Disk drive module not really. Might need some work.

    Burster Digistant 4454 constant voltage and current standard; needs work, batteries died within destroying components with their vomit
    Burster PT100 Simulator
    Burster Thermocouple Checker or somesuch
    Handheld Frequency/Volt Meter combo ; nice for the moving coil dials


    The HP9000 might be a nice ebay profit when I get bored with it. The keyboard alone sells for like 80 bucks.

    There's actually quite a lot of metal in that for a $35ish tool. Is this your first brushless power tool? Once you get used to them, using brushed feels like going back to a hand-crank can-opener or a drill without VSR... :o

    Some vintage LT1088 chips. It measures True RMS voltage by dissipating the input RF power into an on-chip resistor, and heating another on-chip resistor using DC until it reaches the same temperature - the holy grail of RMS-to-DC conversion. I hope to use this chip to verify the performance of a RF power meter I'm building (my RF power meter itself does not use LT1088 as it's long out of production, just performance verification).

    They are quite delightful: Excellent fit & finish; a joy in the hand.  :-+

    Not bought today, but a few weeks ago. I meant to bring this here when I got them, but IRL got in the way.  :o

    Mini-Review here: https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/msg4069663/#msg4069663

    TL-DR version: Piranha teeth!!!  >:D   Serrations are exactly as described in the adverts: Sharp grippy angles, but ground to an inside curve such that the ends of the jaws pull themselves under the edge of the screw head.

    https://www.amazon.com/ENGINEER-PZ-58-Extractor-Combination-fasteners/dp/B002L6HJAA/

    Available on eBay, Amazon and the Engineer website. Amazon is cheapest and next-day via Prime for that "Instant Gratification" fix. ;) 

    Search for"Neji", "PZ-57" & "PZ-58" on your preferred local shopping sites; there are numerous other models sold under the PZ-5x naming convention, but the PZ-57 & PZ-58 appear to be the only ones which have this "precision & quality" build feel.

    They also make some very interesting crimper kits; Cerebus will doubtless be in here crowing a wee bit once his arrives.  :-+

    An iPhone 13 Max Pro with 256GB of ram plus on eBay and a tripod on Amazon.

    Unfortunately it is not the color I like, it is a kind of light gold color (blah, I don't like), the battery is exhausted and needs to be replaced, the micro SIM slot looks damaged and doesn't open, also there are several scratches on the back, not on the screen, on the other side, but the three cameras are perfect! Which is what I need, especially the macro one.

    I only paid 103 euros for the iPhone, it comes from an eBay auction that started at 100 euros, described as "not working, only for parts", and since Apple lists it at 1200 euros, it's a deal of -1100 euros !

    I'm going to use it as a camera, certainly not as a phone  :D :D :D

    Windsor Design #63395 60 in x 20 in woodworking bench. $160 at Horror Fraught:

    https://www.harborfreight.com/60-in-4-drawer-hardwood-workbench-63395.html

    "Butcher block" top is made of reasonably decent sized 1x18-1x24 in strips of hardwood; looking through the dog holes I'd guess 17-19mm thick...?

    Legs and drawer fascia are similar construction; lower shelf and drawer bodies are Masonite, but reasonable heavy both bottoms and sides, and all with flocked lining. Vise should be able to hold a 6x6, it has 19mm steel sliders and acme thread with all cast iron vise hardware.

    Given what a crapwood 48" bench costs at Home Despot, a bargain even without the $20 off coupon; which these sell out in days whenever they do come in stock.

    Mini Retro NES Gaming Console.
    a third of the 620 NES games are clones or unplayable.
    all games require a full console re-set when exiting to the next game or menu.
    the AV video is standard definition with high color saturation.
    this console did not have the HDMI output but if it did, it would still be standard definition.
    the quality of the case plastics shows defects flow marks.

    did a teardown on the console to see if a re-set circuit could be added to the hand controllers.
    by way the a controller button hold-down trigger circuit to poll the reset pin.
    however as shown , this may not be possible. uses chip on board on the hand controllers.
    also the video color saturation circuits are behind an unknown chip on board.
    posted so if anyone wants to try .
    please do share if you can fix or successfully modify this type of games console.
    particularly adding an on controller reset.

    update- added a list of nes games

    in theory how cheap can you get in video game hardware design?
    here is My speculation if further product cost cutting is possible? sadly yes.
    the cardboard box the product came in, could pretend to be the main console.
     ;D
    the two game hand controllers could be in theory permanently linked by a cable then
    also the AV and power cable also run out from of one from console pcb inside one of them.
    eliminating all the USB plugs and sockets . in a hypothetical product redesign. the power &
     reset could be deeply recessed into one of the controllers case.
    off edge of the main pcb useing slide switchs one with a spring return for reset.

    still a fun product as It Is .

    There's something satisfying about using a pencil...I will have to dot a few smaller notebooks around the lab/garage.

    The Hi Uni pencils are excellent as long as you don't overpay (tricky with the current logistical nightmare going on, I paid USD19 for a dozen), the Moleskine is ehhhh a bit expensive for what you get but it's the gateway drug into nicer notebooks so I just had to experience it. I will try a Leuchtturm1917 next...and maybe some Blackwing pencils too.

    Finally a relatively reasonably priced hobby to get into.  :P

    PMT will give you a measurable large current pulse from a single photon, by amplifying the electron count inside it to give a measurable amount. Also can be really low noise as well doing this. Also linear over a massive range.

    For radiation: with a scintillator the sensitivity is MUCH higher. Also you can analyse the output signal and get an energy spectrum, which rather than just showing you something is present will tell you what exactly is present.

    Heck, been a while, work stuff and life overall, not forgetting the family.

    Electronics related stuff bought in the last months:


    (https://i.imgur.com/FcAYVMi.jpg)

    "Supposedly" rated CATIII 1000V - 25A ( :-\). Construction overall is good, silicone cable as the normal test leads, with double insulation, white on the inside and colour on the outside. Plugs are robust, nickel plated copper with good construction and size/grip. Resistance of each lead under 0.08Ohm, measured in the High Res Mode of the Fluke 87V.

    (https://i.imgur.com/Di2elHm.jpg)

    Cable markings are the following:

    (https://i.imgur.com/OC5iFKX.jpg)

    Yes they are not Stäubli MC, Hirschmann, Schützinger, Promona Electronics or Probemaster. But they are a step above the crap I see being sold in the Huaqiangbei markets.

    An excellent plan B is to get a plastic pistol case from your local Sporting Goods store (Academy, Bass Pro Shops, even Wally World) like this one. They sell for $8-20 depending on how deluxe you get on the thickness of the eggcrate and the outer finish.

    Of course, you can also spend a lot more on a similar Pelican or clone case as well. ;)

    I opened the case and measured and all the rails had no output, so I took the power module out to check and didn't see or smell anything wrong. However, just when I tried to flip it over in order to inspect the bottom side of the PCB, I was shocked badly.  :scared:........

    Repaired an old Akai AA-1040 for one of my kids....was aware of the power line capacitors....so used a discharge lead I had made, assumed it would discharge the tanks caps quickly.

    Big mistake....I have the resistance way to high....took minutes to drain 50V DC rail.   I found out the hard way.   I had made it to disch microwave caps.   So had to make a new disch lead.

    Lesson learned.

    I got one of those Sony IMX sensor based HD Usb cameras.  Gives a resolution 3264x2448.  Streaming with a Raspberry PI 3 gives about 0.3fps at that resolution.  However it does only claim a 30fps rate at stupid low res.  So, nice sensor, nice price, either rubbish processor or the PI can't actually handle that bit rate, not worked it out.

    https://www.amazon.co.uk/Magepixel-Varifocal-Webcamera-Difinition-Industrial/dp/B08JTS9KB2/ (https://www.amazon.co.uk/Magepixel-Varifocal-Webcamera-Difinition-Industrial/dp/B08JTS9KB2/)

    The lens is all sorts of weird.  It says 5mm to 50mm, but that's entirely fictional.  It seems it's closest focus distance is about 0.25m, but no where near as wide as a 5mm lens.  This might be that I need to first normalize the focal length with the sensor size, but to me it looks more like a 30mm to a 150mm lense. 

    I can't give you much input on overall quality, because I immediately put it into service watching the pepper seedlings.  So it's about the worst possible scenario for one of those cameras.  A high red+blue spiked 'white spectrum' 30W LED light.  Shiny metal reflective background.  Opened in a photo editor the spectal curve shows the massive spikes, but also some more disturbing bouncing in the lower red spectrum.  Again, it not exactly the best environment and I should really take it out in bright sunlight and see what it can do.

    As a camera intended to just keep an eye on things, I think it works far, far, far, better than any cheap (or expensive) webcam for the purpose.  Not "cheap" cheap at £80 UK, but you can get the bareboards + microlens, maker style boards for about £35.

    They look fine to be sincere, but the quote of CATIII 1000V 25A is the only think that I have doubts of. They will be good for 10A, but further testing should be done to really see what they are capable off.

    It would need some testing as Joe Smith done to test leads in this video (he's an user on this forum) - https://youtu.be/fQowDZstguw (https://youtu.be/fQowDZstguw)

    If we go from what the manufacturer states in their website: http://en.tw-eta.com/index.php?c=show&id=77 (http://en.tw-eta.com/index.php?c=show&id=77)

    The ETA 15KVA cable is a 300 strands per 0.08mm each strand in a 3.9mm outer diameter (copper plus double insulation). It should in theory do the 25A mentioned but we know how over optimistic Chinese are...

    This is something I would be very interested in following; I had an idea for similar abuse of one of the postage-stamp-sized SAMD21 boards. I picked up a few QT-PY and the seeed equiv a while back when I got a bug up my arse to try MicroPython cuz so cheap for so much more power than Ardu. Alas, it was even harder for me to wrap my brain around this time than a couple decades ago. :-[

    My 87V was giving me the low battery indicator so I had to buy a battery for it:

    (https://i.imgur.com/hkYYBJI.jpg)

    Normally I would go for Panasonic Eneloop. The problem is that Panasonic don't have 9V rechargeable Eneloop.

    Now not even C and D size they have, what they have now is adapters where you put one AA and it converts for that size, while before at the beginning when the line was released that option existed.

    The next logical selection for me would be the Evolta Series, but in the official Taobao shop they don't sell the 9V Evolta as the rest of the world, only the Alkaline (gold, red and and blue casing) and the Manganese (red and white casing).

    They also don't have any lithium offering in their line up for the AA, AAA, C, D and 9V. So since I had tons of other rechargeable batteries from GP Batteries (for the kids toys) I was going to go to their Ultra Plus line up since I've been satisfied with their products.

    Don't tell me I fucked up the resize? Since it auto dimensions on the PC (Mozilla) and Phone.

    EDIT: yes I fucked up, put the original instead of the resized one.
    Sorry.

    "Here’s a tough truth for Mac users of a certain vintage to confront: although we might be nostalgic about the Apple of the past, its share price prior to 2004 is pretty much a flat line compared to how it’s doing now. Which is to say, to put it bluntly, that Apple was doing things wrong back then.

    But still, that nostalgia persists for us old-timers. Take Clarus, the dogcow, for example. This was a bitmap glyph originally created by Susan Kare for the Cairo dingbat font that came with the original Mac in 1984. But Clarus broke out to become an official mascot of Apple’s Developer Technical Support, and an unofficial symbol of the Mac for the rest of us.

    And just look at it! It’s solid, 24-karat whimsy! It’s a purely fictional creature—half dog, half cow—that came into being through quirkiness and serendipity, and you could say it has no business in a grown-up, commercial operating system. It makes no real sense, and wasn’t really there on merit or through strategic planning, yet there it was whenever you chose Page Setup in a document.

    I just acquired the HP3456A a couple of days ago and the HP5334B a month ago.  I'm pretty sure I'll need to seek professional help with my HP TE addiction now.

    Bought broken, the counter needed a blown RIFA cap replacement but I also discovered a shorted tantalum on the +12V rail. It has the 1.3GHz C-channel and high-stability oven oscillator options.  I'm really happy with this save.

    The 3456A is pristine!   I think it was mislabeled as broken (needed the GUARD button engaged?) so I got a good price for it.  It more or less agrees with my 34401A (10 months out of cal) on all functions but was 20 counts high on DCV. A simple tweak brought it into line.  All three multimeters are attached to an ADR4530B reference (0.02% tolerance).  I'm lovin' the math features!   

    However, I've read that the ROMs go bad so I'll first desolder them and put them in sockets.  Then I'll burn a new [E]EPROM similar to xDevs' repair (although, I'll put it on a removable daughter board).  Q1: Should I also change the line filter block?   Q2: The filter caps look fine.  Should I change them too?   The latest chip date codes I see are 8147.

    https://www.harborfreight.com/sanding-belt-cleaner-30766.html

    Bought the 2nd up from bottom of the line at Horror Fraught to go with my new woodworking bench from Horror Fraught (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/msg4121005/#msg4121005) so I can cross a few items off the ol' honey-do list, as the Bauer was $46 after $10 off coupon code expiring today. Needed features were ~1KW motor, 3x21 belt instead of 3 x 18, variable speed. Also got a gum brick for belt maintenance. :-+

    Got it home and went to see what belt assortments Amazon had, and this Chinesium belt sander popped up on sale, evidently a price match as within a few cents of HFT's sale price (nothing with above minimum features anywhere near this price first time I looked), but it adds adjustable angle front grip and flip-open nose so it can conceivably be used for detail sanding.

    Now I've got it on the way too, so I plan to do a battle of the cheapies and keep the winner. Unless I hate them equally, then they'll both go back after I finish a few projects.  :-DD

    And yet the people you always read about living to a hundred and something are usually Asians living in Asia... and of course, you know what the primary staple of those diets is. ;)

    I've been doing keto on/off for over a decade... while I do yo-yo, it's the only diet I've ever actually been able to keep up long enuf to actually lose any appreciable weight due to a back injury which limits my ability to remain standing for any long periods of time. The key for me will be to make it the way I eat all the time, which is really hard in a house full of kids.

    But all that misery does make me think... do you suppose maybe Western medicine/dieticians might just maybe have it all wrong?  ???

    I mean... the people who make our food fill it all with fat and starch because that is most profitable... the only way to not gain weight on that crap is to not eat it.  |O

    Yep not the most rigid slide mech on the BV20 so I am considering removing the Compound and replacing it with a spacer block. 98% of what I am likely to be doing will be parallel turning, bores and threads so not a big loss and can be swapped back if needed. Robrenz and Stefan Gotteswinter have videos on youtube showing this mod.

    The whole lead screw on this one needs some 'help' the split pin holding the screw to the gearbox allows 1-2mm lateral travel and the plastic block will likely get an Aluminium/Bearing replacement.

    bought most of what i need for my 'Lumen Tube' project today. (not my design/idea)
    three 4" elbows and a step down for the light meter (UT383BT) bit.

    Depends on how you cut them really and doing a few other tweaks to the Lathe is needed too.
    Sure you can get away with plunge cuts for threading in the smaller sizes or fine pitches but jump up in size with ISO coarse, Whitworth or UNC and use a plunge thread cut instead of compound cutting and it won't go well.

    Compound isn't going away just won't be fitted for general use. Reality is everything I do will be M12 and down 98% of the time. What is this 'Whitworth and UNC' you speak of anyway in our metricated world :-DD

    I had sort of planned on a Lathe in the early part of next year so this is just a filler and will help me do some odds and ends in house.

    a poorish man's way of isolating the light from a bulb, or flashlight from outside sources and measure it's output in lumen. (not calibrated)
    i won't try to explain the mechanics as i would probably get it wrong.
    got the idea from Matt Smith on youtube.
    he first shows an integrating sphere made out of a cooler, later in the video a lumen tube.
    i think he might be incorrect using foot candles though.

    https://www.youtube.com/watch?v=xOE1ykJ5WAU (https://www.youtube.com/watch?v=xOE1ykJ5WAU)

    Texas_Ace over on BudgetLightForum AKA BLF also has built many lumen tubes.
    https://budgetlightforum.com/node/60100 (https://budgetlightforum.com/node/60100)

    the tubes are somewhat like an 'integrating sphere' but more reliable at defusing the focused beams or 'throwers' of flashlights than the styrofoam cooler method.
    if you search for lumen tube and see a pair of lungs, disregard that. lol
    i tried finding a good article on the theory, mechanics etc but found WAY to many bot made articles.  :palm:

    i want to be able to compare lumen:watt ratios for LED light bulbs before and after modifying them.
    with either cutting 1 of 2 parallel resistors on current limiting type PCBs of plastic dome bulbs, or swapping it's value.
    also putting a captive dropper in line with the AC of brighter 'non-dimable' glass bulb LED lights.
    both inspired by our beloved BigClive.  :popcorn:

    contemplating getting a UNI-T cheapo thermal imaging camera (UTI690A) as many LED bulbs seem to run well over 60°C by my finger-o-meter. :wtf:
    would also be handy for many other things.

    also want to see efficiency curves for LED flashlights at different LED driver currents and types to show diminishing results in both directions.
    diminishing efficiency on the low side, diminishing output on the high side.

    if i were just doing bulbs, i would probably had done a cooler box.

    ok, this reply has gone on for way too long.  :=\

    A tiny SkyTronic DMM, acquired from a tool stall at our local 'Antiques Emporium' for £2.

    It carries an entirely believable Cat1 300V rating and has a beautifully high contrast display. It even boasts shielded input jacks, a 250mA fuse, and a PTC - and has all of the current ranges on a separate input. Clearly I'm not going to be using it for anything serious, but it reads accurately and it will fit in any pocket - useful for checking out potential purchases. It is capable of lighting white LEDs on the diode setting. The continuity bleeper is so glacially slow that it is quicker to glance across at the display! I think they did a later version with a pointless transistor hFE socket and less convenient sockets, I don't know it it is was bigger too.

    Somehow I couldn't resist it... It just radiates cute! :D

    That is also sold as the Aneng mini, a nifty little bugger that found its way to a few of us around here. Sure, the 12V battery alone costs many times over the meter, but it is quite useful. I use mine primarily for battery testing, as it shows the current of the battery under load.
    Title: Re: What did you buy today? Post your latest purchase!
    Post by: Gyro on May 07, 2022, 03:42:40 pm
    Ah, yes. There look to be several variants, all seem to have a transistor socket. Mine substitutes a signal output - a 2V squarewave at 63Hz  ??? I was expecting something like 1kHz, I don't think I'll be risking backdriving that setting. The battery tests threw me for a while too (I was expecting voltage under indicated load), until I realised that the probes needed to be on the current jack, I might avoid those as a fuse saving measure!

    I picked up a 2-pack of Varta batteries for £2.79, so a single was slightly less than I paid for the meter!


    P.S. The Aneng looks different internally. No fuse or PTC (maybe value caught up with the engineering!)...

    I bought a new chair. The old one was totally broke down and is headed for the trash. It was a bit of a pain to assemble, took about twice as long as I expected. One good thing is that even with the gas lift all the way down it's still acceptable. This is good for when it inevitably starts to leak and won't stay up. I've had bad luck with this kind of chair over the years and now consider them disposable, so I didn't want to spend a ridiculous amount of money.

    I got so sick of swivel chairs going bad, not so much losing gas as thats a 5 minute job to replace a cylinder, but they always go wobbly or lop-sided on me, probably because  I sit funny or something, anyway, it ticked me off so much that last time one went bad on me I just got a plain old non-adjustable 4 legged dining chair to replace it.

    So I have been waiting on tenterhooks for Fedex to arrive (it was supposed to get here Saturday, but just arrived now). Haven't been out of the house for days so I don't miss the delivery-guy (it needed a signature)...

    But finally. It is here :) MSO8104 - soon hopefully to be *cough* liberated to an MSO8204 with the wonderful help of tv84 :) It's quite the upgrade from my old 'scope (a DS1102D), you can see them next to each other in the photo... The new one...

    - Samples at 10GS/sec
    - Has 1GHz b/w, will hopefully soon be 2
    - Came with a bundle enabling all the options, just registered for the keys for that
    - Can do eye-diagrams and jitter analysis (which is the main reason I got it)
    - Also includes an arbitrary waveform generator, spectrum analyzer, frequency counter, logic analyzer, protocol analyzer, FFT etc.
    - Came with 4x500MHz probes and 2x 1.5GHz probes. I think the latter were a gift because I don't recall ordering them :)
    - Also came with the LA probes (I did order those).

    I am so happy right now :)

    https://www.amazon.com/gp/product/B07WHFYHND/

    https://www.harborfreight.com/sanding-belt-cleaner-30766.html

    Bought the 2nd up from bottom of the line at Horror Fraught to go with my new woodworking bench from Horror Fraught (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/msg4121005/#msg4121005) so I can cross a few items off the ol' honey-do list, as the Bauer was $46 after $10 off coupon code expiring today. Needed features were ~1KW motor, 3x21 belt instead of 3 x 18, variable speed. Also got a gum brick for belt maintenance. :-+

    ...I plan to do a battle of the cheapies and keep the winner. Unless I hate them equally, then they'll both go back after I finish a few projects.  :-DD

       Side by Side: Horror Fraught Cheapie vs Amazon Cheapie:

    (https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/?action=dlattach;attach=1486000;image)

    Turns out... they're both the same exact fucking sander under the plastic shell. Aside from the part that's red on the Bauer, everything... motor, electronics, belt drive to gearbox, even the drive & shoe casting, etc... all exactly the effing same Chinesium bits.

    The only real difference then is the features, aside from the fact the dust collector on the Bauer is 50% blocked due to a design flaw, and doesn't work worth a fuck. The Galax Pro has adjustable front handle, a dust collector that works, and that little flip-up cast cover so you can actually do some inside curves with the thing.  :-+ :-+ :-+

    So... I just took the red one back to Horror Fraught and used the refund to get a jitterbug and sanding discs.  :-DD

    Overall reaction is... for ~$45 either one is more than adequate for occasional use, or professional use as a "consumable supply" type tool. I'd have no problem recommending either one; they both outlast me before they even start to get warm under load.  :-+

    A nice old Ernest Turner Electrostatic Voltmeter. I've never seen one with a FSD as low as 1kV before. It has 3 nice smooth fixed vanes and 2 moving vanes. The needle was catching the scale slightly so I had to open it up.

    Rather surprising is how well it retains its reading from just it's own capacitance when disconnected. The yellow resin rear is an amazingly good insulator, given that I've only given it a quick wipe over so far. I took the first photo several minutes after charging the meter to 1kV. By the time it reaches mid scale, the reading only drops by about 20V/minute and it holds 200-250V for a couple of hours. Its capacitance at zero reading is around 8.5pF, so I estimate its capacitance at FSD to be around 5 - 10 times that.

    I had a 10kV meter as a kid, purchased in Lisle Street for peanuts, but I was unfortunately too young to appreciate it. It would be nice to still have it around today.

    Twenny Dollah JittahBug... Made of WIN! :-+

    That pretty much covers it. If you have any need to sand anything... this thing belongs in your toolbox. Runs smooth at all speeds (yes, I know it's a jitterbug; but no funny crunchy feel or rattles,etc), and has plenty of power: I cannot stall it out even leaning my considerable weight into it.

    It runs cool, has a good balanced feel in the hand, and get this: it has a dust collection system that actually works. No, it's not perfect... but unlike the bad old days, I am not having to stop every minute or two to sweep the surface of my work to keep the dust from clogging the paper.  :-+

    And speaking of the paper... the matching Velcro-oid sanding discs are excellent; $9 gets you a 15-pack, and it lasts very well, provided you clean every few minutes with a welder's wire brush. I used two discs of 150 grit and two of 220 grit for the whole thing, once the stripping and shaping was done with 40/80 grit on the belt sander.

    This little beast is on sale through the 22nd, and for $20 it's a no-brainer. This was literally one of the most pleasant tool surprises I've had all year.  :-+

    That takes me back to many years ago, when one of those travelled around (amongst a lot of other TE) with me when, along with another guy, I travelled the State, testing remotely sited TV transmitters.

    Aspire R5-471T-51UN (https://www.ultrabookreview.com/9304-acer-aspire-r14-review-2/) Flip-Convertible ultrabook in new unused condition, according to Post-it stuck on screen. Even got the original box. ;D


    https://www.acer.com/datasheets/2015/4876/R5-471T/NX.G7WAA.006.html

    Intel Core i5 6200U (2.30 GHz)
    8 GB LPDDR3 Memory.
    256 GB m.2 SSD.
    3270 mAh Lithium-Ion Battery (9hrs)
    I/O: USB 2.0, 3.0, 3.1, Type C, HDMI, SD Card, Audio Out w/Mic
    14” IPS Touchscreen 1920 x 1080.
    Windows 10 Home 64-Bit.

    While not quite as much laptop as my current Lenovo Flex 3 1580U ((Core i7/6500U, 15.8" IPS touchscreen), it was only $80 at the Thrift and doesn't have a cracked digitizer which is a pretty much unobtanium oddball part number.  :palm:

    We'll see... if I can't live with a mere 14" screen after being spoiled by the big Lenovo, I can probably flip it for enough to get something similar.  ;)

    ...

    The idea is more of a portable instrument. At home we are new to DAW and MIDI world instruments so it wouldn't make sense to make a more substancial investment.
    This is mainly intended for my daughter, though I will try to have some fun with it too.  ;D

    I bought the inverted edition (my daughter choice) so take note that it may come with more (or diverse) software than the regular MK2.

    Baby Battery operated Cold Cut Saw. Consider me impressed. Fairly quiet all but sparkfree even on this ancient Galvanised Iron. 6mm Steel cut was fast, cold and very clean only a bit of a deburr then it's done ready for whatever. Never using an Angle grinder again for long straight cuts.

    Seems to collect nearly all of the chips and shavings on the thinner sheet and most of the heavier stock.

    I will add a few more blades to it for Aluminium/Plastic and a timber one as I don't own any cordless circular saws (will be slower cuts due to the reduced speed but ok for casual use).

    Due to 'reasons' it was cheapest to buy it from the UK via Amazon Prime :palm: https://www.amazon.com.au/gp/product/B07HZD9HV4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 (https://www.amazon.com.au/gp/product/B07HZD9HV4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1)

    I was blown away ten or twelve years ago when I finally tried cutting aluminum on my table saw - amazed at how well it went, and immediately went and bought a proper non-ferrous blade for it.  It goes through 1/4” 6061-T6 aluminum like a hot knife through butter and leaves a great finish on the cut.  Based on that, I bought the cold chop saw a few years ago and was similarly impressed.  Not quite as fast as the table saw on the Al, but still plenty quick and a beautiful smooth cut.  So, so, so much better than trying to cut either material with a band or jig saw.

    For Aluminium/Plastic I got a low rake blade for my Tracksaw which works a treat. The Bandsaw for short cuts and curves is great but for long cuts and speed circular blades take some beating. I did look at a smaller blade for the Tracksaw to get the cut surface speed down for steel (not a good compromise because of the higher speed motor) but decided having a portable option made sense in the toy collection.

    Plasma can cut a bunch of conductive metals including Aluminium, Brass, Copper and some of the whacky steel alloys but you really need to consider playing with the Shielding Gas Nitrogen, CO2 and Argon mixes generally. The same thing applies with metal cutting Lasers too.

    Not a fan of Aluminium and Plasma (and I don't have mixed gases) and as I don't build boats saws make most sense for roughing it out.

    May take a crack at it at some point, but think by and large I'll stick to non ferrous blades on the table and miter saws for the al-you-min-yum.  (And thankfully have no inclination towards building boats despite the plethora of anchors I have here...)

    Actually bought them Saturday, but didn't immediately get photos.  Snagged a rather rough looking pair of Dynaco A10 bookshelf speakers for $45.  They were painted at some point (institutional tan #5 - blechh  :palm:), and one of the woofers had a tear in the cone.  Pulled the torn woofer and repaired the rip; it's drying now.  Based on what I've read online, it appears that they originally came out in 1971; if what I think is a date code on the woofer is correct it was made in late 1971 (5071).  They were made in Denmark.  Scraped a bit of the paint off the bottom of one of them and it looks like they originally had a wood finish, so I plan to try stripping the nastiness off & refinishing them, and if all else fails try my first effort at veneering if they're too far gone.

    Back when I did jig & assembly line fab out of 8020 extrusion, the only thing we used to cut the material was a chopsaw with 14" x 60-80 tooth carbide blade. If set up carefully to ensure it is square, you can get accuracy "within a few thou" with finish rivaling milled surface, especially if you bother to set up your cutoff stops every time so your pairs/sets of beams are exactly the same length.

    Regarding plasma cutting and various materials.

    Plasma cutting is essentially melting and blowing away material. So, a good heat conducting material such as aluminium will have a rough edge since the melt zone will be large. Thicker the material, the rougher the cut will be.

    You can cut glass too... Just tack down some aluminium foil or conductive thin metal on the glass to allow the arc to form to start the plasma process and then cut away (or more precisely, melt away)  :)

    cheers,
    george.

    Less what I bought today and more what I bought approx 10 years ago and let gather dust ever since  :palm:. A basket case of a Tek 536 scope that I paid AU$70 (USD$50) for with CA, T, G and B plugins. Today that would be a good deal just for the tubes alone.

    Looked like it had sat for decades in someones moist garage gathering rust and dust, then someone tried to turn it on resulting in a carbon tracking extravaganza in most of the powersupply circuits  :-BROKE. It's also very high hours, or someone robbed it for tubes at some point and someone else restuffed it as the tubes are of all sorts - Aussie, American, British, European.
     After cleaning, grinding away all carbon tracking on the ceramic strips, cleaning relay contacts, rebuilding the fan, replacement of all electrolytics (all leaking >1mA after 30 mins on my cap tester so out they go), replacement of a couple of cooked 6080 tubes and some burnt resistors I got to the point of plugging it in to my dim bulb tester (with 700W of bulbs including the heat lamps out of my bathroom  ^-^) and pleasingly it didn't turn into a giant carbon arc. Running it straight off mains the 'low voltage' supplies (-150, +100, +225, +350V) are solid. The type CA plugin just rails the vertical amplifier for some reason (maybe just needs a cal?) and the CRT powersupply is weak and gets continually weaker as it runs until the trace disappears completely (-800V rail starts strong and quickly droops to -400V, then I cut the power as I don't want to fry anything unnecessarily). Maybe high voltage caps, maybe rectifier tubes, or maybe the CRT tube is being driven such that the cathode current runs away, we'll find out soon enough.  :-+ At least the unobtainium parts (power trafo and CRT) appear to be ok.

    I ordered this ARM STM32F103 board on discount from Newark/Farnell for less than $4.00USD. Looks like they have some still available. Was originally $34USD, looks like they were not too popular, but at the current price seem like a steal, unless they are broke.... and I hear some people don't much like Newark....

    My Newark story...

    Practically a year ago I placed a largish order with Newark/Farnell and in it I happen to include an order for 5 SOT-23 P-channel MOSFETS that happened not to be in stock. I was trying to be careful to only order in stock items but I must have flubbed on this one part.

    Newark dutifully split the order and promptly shipped the in stock items.

    Just today I received an envelope with... those 5 P-channel MOSFETS I had ordered 11 months ago.

    I'm actually very impressed since they didn't charge me any extra shipping or a processing fee. I'm sure they didn't make any money on that line item.

    been wanting a HOPI power meter for a long time. however i wanted one that was more accurate at lower current levels <500mA.
    i've seen them in the past, but when i was ready to pull the trigger i could only find the 20A model.

    bought a ZHURUI PR10 (PR10-E) since it  got a good review from HKJ
    https://www.eevblog.com/forum/testgear/testreview-of-zhurui-power-recorder-pr10/ (https://www.eevblog.com/forum/testgear/testreview-of-zhurui-power-recorder-pr10/)
    http://lygte-info.dk/review/Power%20Zhurui%20Power%20Recorder%20PR10%20UK.html (http://lygte-info.dk/review/Power%20Zhurui%20Power%20Recorder%20PR10%20UK.html)
    [attach=1]

    seems able to read below 500mA (although the current should read 0.002A no? [edit] seems power factor affects how Watts are calculated)
    [attach=2]

    one major gripe is the giant 'Real Time Parameter' along the top of the screen.
    serves two purposes... takes up screen space that could have made the readings larger... and two insults my intelligence.  :palm:
    minor problem is that the clock runs fast. a little over a minute fast in a couple of weeks. i really need to check exactly what % it's off.
    i'm not using the relay/timer function so it's not a problem for me.

    i love that i can set a current limit to have the relay disable the outlet should it go above that.  :-+
    also love that i can set the state of the plug when powered up. on, off, or last state.

    it's funny that Clive bought a 0.0005A-3A meter (AnTai ATX.9801+) right after i received this.
    the auto ranging of the PR10 i think is more flexible. not sure which screen is worse for video though.
    the TFT screen of the PR10 or the flickery multiplexing of the HOPI/AnTai  ::)

    Got one too as it looked interesting for the price.
    However all the links for software and such seem dead in the manual/technical notes from Newark.
    Even with the disparition of coocox.org I would have though that it might be available somewhere.
    Some coocox software bits still seem to be available on the ST site though.

    I got it working directly with STM32CUBE. Just need to download the MCU support package.

    https://www.st.com/en/ecosystems/stm32cube.html (https://www.st.com/en/ecosystems/stm32cube.html)

    STM had a link to the CooCox IDE but it is deprecated in favor of STMCUBE.

    https://www.st.com/en/development-tools/coide.html (https://www.st.com/en/development-tools/coide.html)

    There are libs available on git..

    https://github.com/coocox/embeddedpi/tree/master/lib (https://github.com/coocox/embeddedpi/tree/master/lib)

    The documentation on the board including schematic is here..

    https://community.element14.com/products/devtools/product-pages/w/documents/21091/a-triple-play-platform-for-raspberry-pi-arduino-and-32-bit-embedded-arm (https://community.element14.com/products/devtools/product-pages/w/documents/21091/a-triple-play-platform-for-raspberry-pi-arduino-and-32-bit-embedded-arm)



    My biggest gripe is I did not find a specific USB driver, but it works great with an STLinkV2 programmer.

    It has an SWD/jtag interface so I suspect it will work fine with most any ide that supports STLink SWD/jtag and that cortex chip, like Microsoft Code. (looks like to enable jtag a solder jumper needs to be enabled, see the manual)

    I ordered three more since even de-soldering all the hardware is worth more than $3.14usd and I need to order some AE Caps anyway.

    ...and at 75mhz with 128kb flash it is a great option for general projects, even if it is a bit old, IMHO.

    Just got some avr128db28 chips I ordered on that same order that shipped UPS from the UK. I know that Newark has a lot of issues around orders & shipping during their merger but they seemed to have worked that all out now.

    I love how they are discounting 'old' inventory and make it easy to see on the search pages. Their prices are beating Future 80%+ of the time by a good margin and free shipping over $150 with $9.99 fixed under that. They are doing some things right for a change. They do seem to like most places and are wasting money on their shipping packaging, but that is ever going to be an easy thing to do.

    Just got an ebay find of an old isolation tester made by a company later bought by Gossen- the state is good, probably around 40 years old, uses 6 D-cell batteries (that are new and probably alone worth more that what I paid for everything). Did some quick measurements, isolation check voltage is 660 VDC, and quite precisely 0.2A for checking small resistances up to 4 Ohms- therefore suitable to test VDE 070x compliant the resistance of grounding/PE.
    And a pair of small pliers to cut wires after soldering, the other bigger wire cutter from Wiha for comparison...

    KeeYees ESP32S ESP32 Development Board 2.4 GHz Dual Core WLAN WiFi + Bluetooth 2-in-1 Microcontroller ESP-WROOM-32 Chip for Arduino (38PIN Narrow Version, 2PCS)

    I received a Amazon.com gift card and did not have any ESP32 boards yet so bought these.

    But what a corporate bullshit is with these Amazon gift cards. I never used them so no idea about them. Received an email with the gift card and clicked the link to redeem it. It steered me to Amazon.com and I logged in. No problem there, but then I thought what shall I buy and looked on Amazon.fr, because then I can order without shipping cost, but to my surprise the gift card balance in that account was zero.

    I contacted customer support and it turns out that gift cards are bound to the store they are bought in. So bought on Amazon.com stays at Amazon.com, bought on Amazon.fr stays at Amazon.fr, etc. F...ing bullshit.

    Buying on Amazon.com for me is very uneconomical, with shipping and VAT |O

    It is dumb, but, that means the person that bought them for you probably used .com instead of .fr. If I buy a gift card, we specifically use amazon.ca
    If you wanted to sell to a trusted individual, you could probably sell it for ~95% of the purchase value, if needed.

    amazon card is way better than a prepaid visa in terms of fees.

    I got (but not yet received) a DS1202Z-E from Rigol's clearance page. The father's day 50% off promotion put it quite below a Fnirsi 1014D, so I was hard pressed to let it pass.

    I’ve never had any interest in watches but recently my 20 year old $15 flea market watch has become unreliable so it was time for an update. After extensive research the watch I decided upon is a Casio F201-WA which cost me $20 with free delivery from Kogan. I ordered the watch late on Thursday and it arrived yesterday afternoon by courier, one very satisfied customer I must say.

    Edit: Removed link to Kogan as they had doubled the price of the watch shortly after posting. Furthermore, they were flooding my email inbox with bullshit marketing spam which I had nominated not to receive in my account preferences, they completely ignored my requests to not receive this promotional garbage so I have since cancelled my only recently opened Kogan account.

    example: https://www.ebay.com.au/itm/153107816566 (https://www.ebay.com.au/itm/153107816566)

    Just the clamps. 6 of each.

    All the ones I can find have no insulation around the jaws. Any ideas? Or is Ed just interneting wrong?

    You need to search for 100A ones. I suspect the 100A in the PMPO of Amps  :-DD https://www.ebay.com.au/sch/i.html?_from=R40&_nkw=100A+Crocodile&_sacat=0&rt=nc&LH_PrefLoc=1 (https://www.ebay.com.au/sch/i.html?_from=R40&_nkw=100A+Crocodile&_sacat=0&rt=nc&LH_PrefLoc=1)

    Not as elegant as the CTek ones and without pulling mine out some of those in the link are likely similar length. I limited the search to Oz only and you will save a few $ if you go with the wait and China.

    Got some Fluke 8020A on fleabay in good condition for cheap. According to seller, device has some issues measuring current, and sometimes it would need some re-seating of the probe wires...
    I will see, probably some corroded switches that cause this...

    Does anyone know if those are the original probes bundled like 40 years ago with the DMM?

    They don't look like they are since they look like ordinary banana plugs. (Hard to tell from photo)

    Rebonjour a tout et tous:

    Saturday at a neighborhood street market in Paris near Sorbornne, 5eme
    Huge surprise.. at a stand with old French militaria,

    WOW! a German WWII telegraph key in mint condition with very rare original German cable and plug. Prefect Bakelite housing with warning of HV, on original fiberboard base...
     A super bargain, I was amazed....seldom seen even at gun shows and militaria or ham fleas....

    The last photo is a macro photo of the Waffenamt mark with code number Wa A376 which indicates the German factory and town of manufacture.

    I believe this key is 1942..1943 epoch as afterwards the materials  were scarce...
    A fine museum piece for an exhibition.
    Any telegraph key experts please PM me as we seek more info on this.

    Bon Soiree!

    A Peaktech 2025A. Why? Because it connects via USB serial and is therefore no USB HID device. Important, because I want to operate it connected to the prog. "Test Controller" by HKJ and "Profilab", which both do not support USB HID devices. Moreover, it is in the cheaper range.

    HKJ was kind enough to put quite some work in preparing his prog. to include a driver for the 2025A. This driver will - as far as I know - be included in the next major update in due course.

    So now I can simultaneously log up to three temperature sensors of the resistive type. Sensors are dipped in water. See PIC with the money shot. YAY!

    qty=5, Mastech M9803R, old new stock, unfortunately with neither battery nor probes

    Paid 72.90 Euro each, one for me, four for my friends, plus 42 Euro for shipping(1) it from a Belorussian remote place to Estonia, and from Estonia to here.

    The M9803R isn't the perfect *bench multi-meter*, but for that price, it looks like a bargain, plus it offers a serial RS232 on the back that is exactly what I need and want to have :D

    Always wanted one of these but would never pay the inflated "educational" $600 pricing...  But if you are patient they can be had for around $100 on eBay.  Mine was NOS with the keys still attached to the handle.

    You can never have enough breadboard development area.  Triple linear bipolar power supplies (~1.5A ea) and analog function gen are bonus points (square wave even has pwm capabilities).  Breadboard is attached with Velcro, so it can be removed or swapped.  Most of the switches and the leds are logic based, so they are debounced and provide high/low logic signals for easy integration into projects, while others are basic switches for analog use.  The DB jacks are handy for serial projects or expansion to additional external boards and the BNC jacks are great for scopes.

    The case lid is permanently attached and does not fold all the way back (though it has funky hinge clips which make it rather sturdy in it's vertical position), which is a PITA but I think I can come up with something to make it removable to reduce the footprint area.

    Overall it seems pretty well made with nice toggle switches and knobs.  The manual includes the schematic and adjustment procedure for the various analog components such as the function generator should servicing ever be needed.

    WALLY WURLD TOOL ALERT: Hart SS DirtSucker for 30 Bux

    (https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/?action=dlattach;attach=1525642;image)   
    https://www.walmart.com/ip/HART-8-Gallon-6-Peak-HP-Stainless-Steel-Wet-Dry-Vacuum-VOC812SW-3701/106550327

    This is for my fellow eevBloggers here in the states; a clearance sale you might be able to get in on if you're lucky and one of your local Wal-Marts has one or two still available for sale online.

    Wally Wurld recently issued a price rollback on their most expensive Hart Shop-Vac; so when this came through my inbox yesterday, I jumped on it. They didn't have any in the store to buy in person (I drove right over and checked), but the website said my local store had 4 that could be purchased online for pickup next day, and the checkout promised they would substitute another unit of equal value if they didn't have it. So I bought and sure enough, got the email while I was out doing other errands that it was ready for pickup.

    In case you don't know, Hart is WalMart's current "Value Line" of Chinesium housewares and tools; their answer to B&D repeatedly getting (https://www.eevblog.com/forum/index.php?action=dlattach;topic=81471.0;attach=779856;image) by Horror Fraught.

    I'm not sure if they're disco-ing the whole HART product line, or if just their dirtsuckers. I've actually shopped similar-looking units (as in, I'm sure it's exactly the same thing with other colors and name on it) sporting the Stanley and Craftsman brands for $120-140.

    This one has of course the primary attraction of a stainless-steel tank, but other things made me look twice too:

    Tank Drain (so many of the budget Shop-Vacs omit this now) to dump water with some measure of control

    Great big 140mm wheels on back so it actually rolls in the shop & on the driveway

    Nice big tilt handle like real industrial equipment

    2-inch hose: I consider this a reasonable compromise between 3-inch "real Shop-Vac" hose and the 1 1/8-inch hose usually provided with the budget models

    Reasonable power for size: 6A Peak/LRA is pretty average; but rated 11.5A at 120V is pretty much exactly same as my "real" Shop-Vacs. Almost 2HP  :-+

    Tall format means okay for shop use, but should still be very handle-able for cleaning stairs.

    Things I found once I got it home and fondled it:

    Ooodles of suction, but moderate noise thanks to huge 7-inch dia x 6-inch pleated filter

    Oversized rocker power switch with very light, smooth action

    Good assortment of useful attachments, including a floor squeegee for the gulper nozzle that looks like it'll actually work

    Assembly was very simple and straightforward even without RTFM; and all the bits for the wheels actually have screws to hold them in.

    Bottom line of course is still the bottom line: How long will it last?  For $30, I think it'll be hard not to get my money's worth.

    No, seriously; it sucks dirt. And pretty much everything else it comes in contact with; it's almost like having a little tame singularity.  :-DD

    The boy wanted to play with the new toy... so I let him. Surprisingly, he actually got something useful accomplished: All along that hedge there was unswept clippings from me doing the hedge-trimmer thing; over a foot out from the hedge and easily 4 inches deep. In there is everything from paint chips where the painters scraped the house to flaked off chunks of drywall & concrete to leaves from the garage and of course, all those hedge trimmings. Thing ran for easily a hour straight, and while the cord did get warm to the touch, no funny noises or smells.  :-+

    TeleDyne T3DSO2012 for $275 (Thanks again for the heads-up, Kosmic!  :-+) from eBay seller lecroyfinds (https://www.ebay.com/usr/lecroyfinds); they are LeCroy USA's factory outlet shop, so full manufacturer warranty too. My order came problem-free a week earlier than promised.

    NOTE: If you're not from the USA, buying from them can be a hassle if not impossible; they warn you in the listing that they require some paperwork due to government regulations on export of tech. There are some horror stories in the feedback, but they all might be people who just couldn't meet the export end use criteria that LeCroy/Teledyne is bound to, and resultant shit-posting. Check feedback and decide if it's worth the hassle to you.

    UPDATE: Kosmic reports that his sale fell through; first they told him they don't sell to individuals outside the US, then when he filled out the End Use paperwork to run the sale through his business they canceled, only stating "Hello, your EUS was rejected for reasons they are not at liberty to discuss."

    So... unless you're in the US, probably not likely gonna be able to get in on any of their deals. FWIW, my sale was as a individual in the USA.

    picked up the well known electronics textbook - Microelectronics by Millman & Grabel, from my local charity shop, today. Having gone into town to get a copy of "Unknown Pleasures" from HMV. Though not in stock so I downloaded that. Not wholly dissimilar cover art.

    https://en.wikipedia.org/wiki/Unknown_Pleasures

    Used that edition of Millman and Grabel during my EE degree - overall I think it is quite good.  Smaller than Sedra and Smith because it doesn't seem to hold your hand quite as much and has less content.  The main missing item (for me) is the T model of BJTs, which I find very helpful for back-of-the-envelope calculations.  My copy has the 'normal' cover art; yours is different but is the same as some other international versions of texts by that publisher.  I have a copy of Basic Circuit Theory by Desoer and Kuh that looks exactly the same.

    Back in the day (30-35 years ago) I listened to a lot of Joy Division   :-+

    Hope you enjoy them both!

    Makita die grinder DGD800 with 6mm collet.

    collected today - I anticipated that I would need a 1/4-inch collet, which proved correct.

    ... and the one I got of course wasn't suitable.

    On the bright side we make Makita's in the UK. - pity you didn't put a 1/4-inch collet in guys.

     :-DD Been there still doing that for the one I brought several months ago but IN REVERSE  :palm:

    In Oz the DGD800 is sold standard with a 1/4" Collet so it suits my nice expensive Sutton Burr set (on the right) :-+

    Decided to buy one of the cheapy sets off evilbay for a bit more variety and lower care factor for under 20% of the cost. Sold as a 1/4" shanks but Noooo sure enough they are 6mm  :rant: and I have no collet to suit. So off to evilbay to buy a 6mm one, real deal ex UK is stupid expensive so I order a 'Makita' compatible one - FAIL  :palm: along with a 1/4 x 1/8" reducing sleeve so I can fit in Dremel sized bits.

    So more a case of taking into account 'local' Metric/Imperial issues than a conspiracy it seems. Still need a 6mm collet when I feel the need to search again.

    For others playing along at home the Real 1/4" Collet is on the Right the obviously wrong diameter one is on the left.

    6mm Collet part # 763670-3
    1/4" Collet part # 763673-7

    Might be my Google Foo is in form but MakitaUK show it as a part at least also a source in Estonia on evilbay eBay auction: #193715786164. I was getting hits in the UK for the 6mm one from the UK.

    (https://www.eevblog.com/forum/testgear/siglent-sds2000x-plus-coming/?action=dlattach;attach=996179;image)

    My current "On The Bench Today" project is a economical set of LA probes for the LeSiglent T3DSO2012 (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/msg4271242/#msg4271242) scope I bought a few days ago.

    I have a copy of eevblog member TK's Siglent LA adapter PCB (https://www.eevblog.com/forum/testgear/siglent-sds2000x-plus-coming/msg3079002/#msg3079002) on the way because the layout lends itself to my intended means of attacking the problem: solder a piece of socket header on the edge of the PCB and just plug the HP pod directly onto it as for my hobbyist use, I don't expect to need more than the 16-18" those whip leads already provide.

    Okay, also because the BOM is: $15. Boom! Seeya! Done! :-DD   I figured it was something I could just throw a little money at and hopefully it works as well as it did for him; otherwise, I either get the braided cable he recommends and try it that way, or I get a few copies of oz2cpu's Siglent LA Adapter PCB (https://www.eevblog.com/forum/testgear/diy-logic-analyzer-probe-and-pods-for-siglent-scopes/) made up and build that with the same pod.

    (https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/?action=dlattach;attach=1534219;image)   https://www.ebay.com/itm/294846434318

    I've shopped around and seen the HP LA pods going for ~$20-25 with a few grabbits; but since TK's PCB was so reasonable, I splurged $35 on this HP pod which appears to be NOS and in unused condition, with all the whip leads and a full set of HP grabbits.

    We'll see how it works out.  :-//

    Quick fix for that (once you're back to normal) is to allow cookies and log into the right Aliexpress, then switch to greylist the site. Greylisting dumps the cookies after a session, but the pre-greylisting cookies will always be there so you get the benefit of always starting with the same setup, normal ops during that session, and any strangeness going away when you shut the browser.

    Arrived yesterday in my post locker located near the airport: a brand new "Terra Peak Active 20" blue backpack (Made in German) :D :D :D

    Early this morning I took the road bike, drove to the airport, my post locker, took the package, unpacked its contents, bought a quarter of liter of water, a swimsuit and a small towel (these two from an Amazon-hub, located near the airport), put them into the backpack, put on the backpack, and went back with it to test it on 51 Km back to home.

    Test passed! It is big enough to store other stuff for my bicycle trips around the lake and the backpack is very comfortable, small, but not too small, and very ergonomic!

    Looking for a scope for use at my PC. The Micsig is OK but a bit in the way (not a lot you can hide in front of a 43" screen) and the Fnirsi is a pile of crap (being generous there). I've always steered clear of PC-based scopes but now there is screen real estate to spare perhaps a revisit of prejudices might be warranted.

    Wound up looking at the Instrustar ISDS205A and then Hantek equivalent (or vice versa), which looked kind of OK but have potentially fragile inputs. We're looking at around £70. One thing led to another and I am looking at a Picoscope 2204A at £114, rather more than I was intending to lose. But over on Amazon (https://www.amazon.co.uk/dp/B00IOQMVTK) they seem to have got the sums wrong an listed it at £94.80, almost the VAT-free price. I'd read that the software was not too hot, but at that price...

    Turns out the software could be better but isn't that annoying. Worst trait I found so far was installing in program files without even asking, but I think it can be safely moved from there after install. Perhaps my expectations were particularly low, but it's massively better than the Fnirsi thing, albeit not quite as portable.

    A question about the SDK08 clips... are the shafts insulated?  This video suggest they are not:

    I can almost never resist a bargain, so I bought this 3d printer for $59.99usd+tax at Microcenter. New unopened and the last one in stock at that store.

    (Stock picture, as mine is disassembled on the bench, see below)

    This is the V2 and is very different that the original version.
     
    It is available from Monoprice at $199.

    https://www.microcenter.com/product/600161/monoprice-mp-mini-delta-3d-printer (https://www.microcenter.com/product/600161/monoprice-mp-mini-delta-3d-printer)
    https://www.monoprice.com/product?p_id=21666 (https://www.monoprice.com/product?p_id=21666)




    This is exactly what I was looking for to print small ABS parts.


    It prints well enough for the cost, and it looks to have mainstream parts, if they are not fakes.

    The biggest issue is so far is the 12v 5A power supply is lacking power at high temp settings and the brick gets very hot. That's why I opened it up to see if there is a good place for a Voltage regulator so I can maybe use one of the 18v 9A Lenovo laptop power supplies I have in my pile of junk.

    Ordered some SMD clips for measurements. Arrived today. Note the raster on the paper is metric 1mm.

    A question about the SDK08 clips... are the shafts insulated?  This video suggest they are not:

    https://youtu.be/wBzz4T9LOMw&t=3m34s (https://youtu.be/wBzz4T9LOMw&t=3m34s)

    There is another version which advertise the shafts as being insulated:

    https://www.aliexpress.com/item/3256803615039165.html (https://www.aliexpress.com/item/3256803615039165.html)

    and they can also be seen in this video:

    https://youtu.be/8XK_EcSNOT4 (https://youtu.be/8XK_EcSNOT4)

    You can see close-ups of the ends at around the 2:00 mark.

    The clips I got are insulated. There is transparent insulation around the long shaft. The outer shaft between the plastic parts is neither connected to the inner pin (so you could not measure at that point with a probe).

    Looking for a scope for use at my PC. The Micsig is OK but a bit in the way (not a lot you can hide in front of a 43" screen) and the Fnirsi is a pile of crap (being generous there). I've always steered clear of PC-based scopes but now there is screen real estate to spare perhaps a revisit of prejudices might be warranted.

    Wound up looking at the Instrustar ISDS205A and then Hantek equivalent (or vice versa), which looked kind of OK but have potentially fragile inputs. We're looking at around £70. One thing led to another and I am looking at a Picoscope 2204A at £114, rather more than I was intending to lose. But over on Amazon (https://www.amazon.co.uk/dp/B00IOQMVTK) they seem to have got the sums wrong an listed it at £94.80, almost the VAT-free price. I'd read that the software was not too hot, but at that price...

    Turns out the software could be better but isn't that annoying. Worst trait I found so far was installing in program files without even asking, but I think it can be safely moved from there after install. Perhaps my expectations were particularly low, but it's massively better than the Fnirsi thing, albeit not quite as portable.
    I’ve been using my 2204a for a handful of years now and am still pretty happy with it. If you want to make Bode plots, I do recommend downloading the free FRA4Picoscope app, which automates them.   
    https://bitbucket.org/hexamer/fra4picoscope/wiki/Home (https://bitbucket.org/hexamer/fra4picoscope/wiki/Home)
    The picoscope6 software has a lot of features that can take time to learn, and of course has some quirks.  Picoscope7 looks like it eventually will be a little better, but is still under development and missing a lot of features.

    I've finally won an auction for a good precision balance (Sartorius MSE2022), these can be a little rare/expensive depending on the capacity range you need.

    Now my pizzas and other baked goods will turn out a bit better (yeah right  :P). I only had 1g readability before so upgrading to 0.01g will make it easier to measure things like salt and oil in the same mixing bowl. 2Kg capacity is more than enough for my stand mixer bowl.

    Woohoo no more strain gauge shenanigans for me, they were always slow to respond when making small constant additions so I would often overshoot.

    The yellowing is just the clear plastic cover so it should clean up nicely. It would be around $170 shipped which is quite a deal considering they're like $2500 new. The weak yen is helping a lot, I'll have to stock up on some car parts too.

    Once you have the masspiece set you will need to send it off for certification. I know my set at least down to the nanogram resolution, and as the massmeter used to reference it is actually verified by a masspice, and this massmeter is also used to self calibrate itself every 6 months using the local SI kilogram reference unit, I am pretty sure of them being correct, and traceable to the standard kilogram to a good few decimal points, seeing as the error between the standard kilogram, and the new SI defined kilogram, is in the order of a few hundred picograms, but is now reproducible anywhere, without needing to take a trip to the landlocked separate country in Paris that houses the SI standard.

    Knowing I have a 1.0000g masspiece as reference, and a balance that actually has the ability to see the 1.000g mass, is the start of that rabbithole. And yes, I have seen that Platinum iridium alloy mass, in it's glass case in the safe, within a safe within a safe, cut into a hill in a vault by me, a few times.

    Yep for better or worse that's my friend's preference so it took a while to track a Sartorius down. He said Mettler were "fine" but the Sartorius balances tended to show excellent stability over time.

    It worked out better in the end because it seems Mettler are more well known so they command higher prices on the used market.

    Nice ! 
    Does yours also have auto-calibration mode ?

    I got a Mettler 12kg scale precision 0.1g on an auction in 2006 which is very nice for cooking but also measuring precise volumes of certain fluids etc.
    I always power off the scale and only on when I need it. After two minutes of idle it does the auto-cal mode.
    Back then I also bought a brass weight of 300.0 grams so I could keep track if it would deviate over time, it didn't still exactly 300.0 grams.

    I bought a nano VNA S-A-A-V2 a while ago (turns out it was a clone) and was impressed by the two 12 inch SMA cables it came with. They aren't your ordinary cheap cables. So I looked on eBay for someone selling cables with blue insulation like those. I found something and ordered three 12 inch cables: one RG402, one RG405 and one LMR195 from bydpete (about $4 US each). I just got them today and measured them along with two random RG316 cables (I have PILES of random RG316 cables accumulated over the years) and I like the LMR195 cable. I attribute the ripple in the S21 response to the SMA connectors. I read that the seller can offer cables with better connectors, so I've sent a message asking about that.

    In the picture the cable that came with the nano VNA is on top. The three cables I just purchased are below it. The two random RG316 cables (beige color) are at the bottom. The RG402 and RG405 are semi-rigid, the LMR195 is more flexible. The nano VNA cable is also very flexiible. Wish I knew how to get some more of those. I used to work mostly <1GHz, but have more recently been doing stuff at 5.8 GHz. You can't just grab any cable out of your pile for that.

    Yep it has internal calibration, and apparently it can self-level too!

    It can be a bit scary buying a balance with internal calibration because you're supposed to "lock" the weight by turning a screw or something so it doesn't move while shipping but chances are when dealing with sellers on auction sites, they won't do this. Fingers crossed.

    Now I'm on the hunt for a nicer battery powered one...for the two times a year I have a barbecue outside.  ^-^ (ignore the fact that I can't think of a use case yet)

    From one of our local 'antiques' emporiums: Item described as "Old Tin" for £5, turned out to be an unused NATO Hellermann wire stripping set. It comprises a decent Ideal [Custom] Stripmaster automatic wire stripper with 4 different size sets of metric blades (15 diameters), a flat cable shear, and two different sized Ideal coax cable strippers, again with spare blades. Things needs a bit of a clean up due to age everything is clearly unused.


    Edit: I've just looked up the prices of the mil spec Custom Stripmaster and blade sets. Maybe I should trade it for a scope!  ;D

    I have been busy buying up even more test gear in the last couple of weeks. Not what I could honestly describe as " a score" as I paid  a fair price.

    Not pictured are a Datron 4910, 3x Fluke 732A, plus a couple of high quality resistor standards by Welwyn but all included in my latest attempt to complete a home cal lab.
    If anyone has information or manuals for the Datron 4901/4902S/4903 I would be grateful for any information about this antique setup. My plan is to upgrade my calibration equipment & sell whatever is surplus to get some of my money back before the next opportunity to spend comes along.  I hope that this will keep me happy for a long time but I suppose it all depends on what I find next.

    I've been looking for them on eBay for years, but they are fairly rare.
    We used to use them back in the day, when we ran out of RS SWOB Polyskops to take on maintenance runs.

    The Polyskop was the "preferred option" & to be fair, is a bit more "user friendly", plus has that BIG screen, but a 'scope & a 2002A don't stretch your arms as much! ;D

    I just picked up a Picoscope 5244B on epay.  It is a 2-channel, 200 MHz scope with variable 8-16 bit resolution, 512 MB of memory and a built-in 20 MHz AWG.  Dave did a teardown of a model in this series (5443B) a bunch of years ago at a trade show.  I got it for $450 with the nice Picotech 250 MHz probes, which I think is a fair price since the retail was $1975 and the new version (5244D) goes for $2315.   However, the seller accepted my offer so quickly it makes me wonder if I could have gotten it for an unfairly low price!

    In any case, it is quite the upgrade from the pico 2204a that has been my only scope for the past handful of years.

    Loading  in 7603 and 7904 Tektronix mainframes, the scopes needed astigmatism and geometry trim on Z axis PCB, for a bright, clear, focused and aligned display. Unearthed my old 7L12 as well

    The 7L5 had A few flaky connections, after contact cleaning, in CAL, dated circa 1980!

    I know you are right.  And it works great - used tinySA as source and bandwidth is 200 MHz as advertised, high-resolution modes show great detail, signal generator is really nice,  etc.   The cosmetic blemish I was expecting based on the ebay photo turned out to be a piece of scotch tape on the front panel that just peeled off!  I am very happy with it.

    I needed some new speakers for by my test bench and I came across some sales on Newark(Farnell) and I bought two sets of these Bluetooth ceiling speakers for $10.37usd (was $122.00usd) per pair.

    For that price I am not expecting much, but they came today and I am unboxing now, will update here shortly.

    It includes 24v 2.5Amp 50/50hz power brick.

    The instruction book says enter 0000 as the Bluetooth pin, but that doesn't work. Password printed on the back of the active speaker DOES work.

    no base, but given the stated frequency response as 60hz-120khz that is no surprise, not being an enclosure right now doesn't help much me either me thinks.

    with 30watts RMS per speaker there is not a lot of volume being driven by my windows10 desktop, but for ~10.00 for a pair, I am pretty happy right now.

    I bought five NEMA17 steppers from VEVOR. Includes wire stripper/cutters and electrical tape, not sure why since they have dupont connectors.

    Oh it doesn't include the wire stripper, its equipped with a stripper:

    Quote
    【EFFORTLESS TO USE】- The stepper motor is equipped with a wire stripper commonly used by internal electricians, motor repairs, and instrument electricians to strip plastic & rubber insulated & cable core wires. Insulating rubber tape with excellent insulation performance and good adhesion to prevent leakage.

    Thought I would need a laser engraver, so I bought one. Atomstack A5pro+. This was cheap to start with. First test, laser power was a little high (from the database).

    Big thing to be really careful with open Laser engraving or cutting is where the beam can go if reflected and what fumes/poisons is the material giving off. At minimum open doors and windows but far better put a proper cover over it with extraction to the outside both for your lungs and eyes.

    So many MORONS with 'free' ones of theses on youtube literally blowing smoke up Bangoods ass while simultaneously sucking it into their lungs.  :palm: Play Safe  :-+

    I had to restart a computer today and when I did, for some reason it couldn't get a network connection. I noticed the LEDs on the switch it was plugged into were blinking in a mad, crazy pattern. I tried the usual fixes but only bypassing the switch and going directly to the router worked. I used the same port as the switch, so the router isn't part of the problem. My NAS was also plugged into the switch and to get it back I'd have to disconnect a printer. No real problem as I have only used the printer once or twice in the last year, but I decided to buy a new switch just to put things back as they were.

    I got something around 10 years of use from the switch, so I didn't have any problem buying its successor. It's even cheaper.

    (https://m.media-amazon.com/images/I/71kcM4nLRjL._AC_SL1500_.jpg)

    To ensure some future fun, I added the 8-port "managed" version to my order. Considering I now qualified for "free" shipping, it almost cost less than the 5-port version.

    I'm thinking I should also buy some kind of back up router - just in case. Electronic stuff tends to fail at odd times for strange reasons. Last year, as far as I could tell, my cable modem died because of loud thunder.

    Used it outside for testing and probably will do so ever. Enclosure to come.

    A1 SIZE CUTTING MAT

    https://www.amazon.com/dp/B08FM3ZP4V

    Today I found this one; a 5-layer mat with a nice metric side, and with the current 20% discount it's only $26.

    When it gets here in a few days I'll followup with real pics and first impressions. If you're needing a new mat, this could be a killer deal. No idea if those outside the US can find this one with similar discount.  :-//

    Yeah, the point for me was not to use as a cutting mat, but as primary work surface to protect my marble countertop slab workbench from dwagon-paw ham-fisted carelessness.  :-DD

    If it would fit, I'd probably have gone with A0 to have as much coverage as possible.  :-DD

    Construction is a really nice, dense 5-layer with solid layers and foam with just the right rigidity and a nice grippy surface, over 3mm thick. Heavy too; balanced on edge on my kitchen scale, it weighs 1.7Kg.  :o Even working right on it like this, outgassing plastic smell is barely noticeable. Much better than my last two mats.  :-+

    So far, I quite like the initial quality of this mat. At $26, a steal of a deal... but evidently it is sold out right now.  :-// I'd say it still warrants watching to see if it comes back in stock; even for a few dollars more than the Fiskars, I would take this one first. I like the protractor print better than the Fiskars nested rectangles, and it doesn't stink me out of the house.

    Nope. Primary purpose is to protect the benchtop; nothing more.

    I'll worry about putting down a ESD-safe mat during the rare few times I'm ever working with such sensitive parts out of circuit; otherwise I'll continue just making sure I discharge myself before fondling my electronic junk.

    Yes, it does seem a bit of an overkill for such a rugged brick, it's kept it in excellent cosmetic condition though. I think it's the same case that was used for military use, there's an ebay seller in the UK selling them for £25 each - I only paid £30 for the meter, case and leads!

    Well some updates: my birthday was some weeks ago and my neighbour, who have a huge collection of model kits just offer me another thing to add to my hobbies (and the ever-growing lack of time):
    (https://i.imgur.com/jOG7f1U.jpg)

    (https://i.imgur.com/Jy4FnXB.jpg)

    These are Gunpla, basically model kits based in an old super robot anime/manga. Not only it is a huge franchise that had entries since the 70s but it is also one of the only where the realism is prevalent in the robots, since mechanically and functionality could be something that we in the future with the advance of technology could achieve as a race.

    Plus I bought two things that were in my cart for a while:
    (https://i.imgur.com/DOkWNNQ.jpg)

    Casio GShock GW-B5600HR. It wasn't my first choice, I wanted the GW-M5610U-1B that is similar in everything (Solar Charging and Atomic Clock sinc via radio frequency) but didn't had Bluetooth. But since I was able to get this one new, cheaper than the model I wanted, I could not say no to it.

    Also since my old Felo Interchangeable VDE kit is going to be used exclusively at work, I bought this one since for years I've been wanting to give a go to Wera or Wiha:

    (https://i.imgur.com/34qoNRn.jpg)

    Same as the Felo kit, but with 2 grips instead of 1 and a better variety of screwdriver shafts. Overall a good kit. I have some more stuff on the cart from Wera and Knipex (another brand that I see being thrown around here constantly but never had any product from them) that I want to try. And probably one more DMM (or 2 depending of how the deal goes) because you can't have enough measuring tools at your disposal.

    Nice square, I have the basic G5600 which just has solar. I sometimes have a problem with water ingress so I had to re-lube the gasket, they were strangely bone dry when I did it. Maybe I have a leak through the buttons too.

    Sometime in the future I want the fancy made in Japan ones with a metal body and screw down case back.

    You can find super cheap screen protectors for them. I'm clumsy and I manage to scratch up even my sapphire crystal watches lol.

    Strange that dry gaskets on this watches are not that uncommon, specially in new watches. I've been reading some reports on Reddit about it, like 2 to 3 times a month, mostly from modders who buy watches to modify.

    My ten years old Tomtom Urban Rider needed a new battery.
    Unfortunately they used tamperproof hex screws (2mm) and Torx T6, so I bought this very nice
    safety bit box set.

    First I had a look at the cheaper chinese bit sets on amazon but often I found reviews from customers that
    complained about the quality or missing/duplicated bits. Particularly they complained that the holes in the
    tamperproof bits weren't centered. So I bought myself this one:

    https://www.wolfcraft.com/products/wolfcraft/en/EUR/Products/Machine-Accessories/Bits/Bits/Solid-Bit-Sets/Safety-Bit-Box-for-Safety-Screws%2C-31-Pcs-/p/P_1386 (https://www.wolfcraft.com/products/wolfcraft/en/EUR/Products/Machine-Accessories/Bits/Bits/Solid-Bit-Sets/Safety-Bit-Box-for-Safety-Screws%2C-31-Pcs-/p/P_1386)

    Very nice quality.

    Well some updates: my birthday was some weeks ago and my neighbour, who have a huge collection of model kits just offer me another thing to add to my hobbies (and the ever-growing lack of time):
    (https://i.imgur.com/jOG7f1U.jpg)

    (https://i.imgur.com/Jy4FnXB.jpg)

    These are Gunpla, basically model kits based in an old super robot anime/manga. Not only it is a huge franchise that had entries since the 70s but it is also one of the only where the realism is prevalent in the robots, since mechanically and functionality could be something that we in the future with the advance of technology could achieve as a race.

    Plus I bought two things that were in my cart for a while:
    (https://i.imgur.com/DOkWNNQ.jpg)

    Casio GShock GW-B5600HR. It wasn't my first choice, I wanted the GW-M5610U-1B that is similar in everything (Solar Charging and Atomic Clock sinc via radio frequency) but didn't had Bluetooth. But since I was able to get this one new, cheaper than the model I wanted, I could not say no to it.

    Also since my old Felo Interchangeable VDE kit is going to be used exclusively at work, I bought this one since for years I've been wanting to give a go to Wera or Wiha:

    (https://i.imgur.com/34qoNRn.jpg)

    Same as the Felo kit, but with 2 grips instead of 1 and a better variety of screwdriver shafts. Overall a good kit. I have some more stuff on the cart from Wera and Knipex (another brand that I see being thrown around here constantly but never had any product from them) that I want to try. And probably one more DMM (or 2 depending of how the deal goes) because you can't have enough measuring tools at your disposal.
    couple of years ago, I got a Felo kit as a Christmas gift and absolutely love it.  Meets all my household needs.  How do you like the Wera?

    GreyWolfe, is definitely different in the grips. At first use the grip was strange since I was used to the more cylindrical shape of the Felo. But with time it kinda turns more comfortable as soon you relearn how to grip it.

    The handle locking mechanism is better than the Felo, there is less chance of pressing the button to release by mistake since the locking mechanism is on the top of the handle, surrounding the hole to slot the shafts.

    The blade variety is better, with an extra Tork 25, a PZ1, imperial PZ #1 and #2 and 1 flat head 0.6*3,5 slim type for terminals.

    Here's the contents of the kit:

    (https://www.weragereedschap.nl/17229-large_default/wera-kraftform-kompakt-vde-17-delig-universal-1.jpg)

    Unfortunately the Wera misses the top knob you could put on the Felo shafts and turn into low torque, precision screwdriver.

    I would gladly exchange one of the grips for a precision like one or for Wera to have one available since the case itself still have a slot available for another blade (that is the space of the voltage tester that is not included in this kit).

    I also would see the elastic straps of the handles in the pouch to lose their force, compared to the metal box (my Felo kit is the old style with the metal box, while the new ones is a molded plastic case) with plastic holders of the Felo.

    But in terms of use both are excellent kits. I would pick the cheapest one always, since both cost almost the same new. You can't get wrong with any of them.

    Both are well constructed, have build quality and are VDE and IEC certified.

    As I told I pick up the Wera not because I was dissatisfied with my Felo, but because I wanted to separate work from personal tools. The Felo is still going strong, 14 years after I bought it.

    Although I need to send an email to Felo asking for quotation for a new grip and one PH2 blade, since both are starting to show some wear and tear.

    Faced with the prospect of desoldering all of the RAM chips (and a few custom chips which are harder to replace, Jameco still has the RAM chips available!) in the below, I have just bought one of these (https://smile.amazon.com/gp/product/B07542D82F/ref=ppx_yo_dt_b_asin_title_o00_s01?ie=UTF8&psc=1) based on watching this video (https://www.youtube.com/watch?v=XQVjwPsVFd8) about how these desoldering irons work.

    One concern is that these PCBs have very delicate (due to age) traces snaking between the pins on the top layer, so getting as much solder out and then using hot air to help lift the chip seems to be the best approach. Getting solder out has always been a bit hit-and-miss with the separate manual solder-sucker pump types, so I'm hoping the built-in vacuum pump will work a lot better. I really don't want to break those traces...

    Hi,
    At work we use a Metcal desoldering station, connected to external airpressure.
    No problems to desolder up to 6 layer boards, it´s very sensitive to the soldering pads - After all, the pcb looks like it ewas never used...
    Other method when it´s clear the IC will be replaced:
    Cut off the pins of the IC* which should be replaced, then heat the pads and take the pins out with a tweezer.
    Then use a good desoldering pump (Soldapullt for example), without the IC pins it is much easier.

    *) suitable tong will follow

    I'm just going to flat-out say that anything with the word 'Metcal' in it, is out of my budget :)

    I used to work in R&D., we had an absolute marvel of a lab-manager(ess) who could solder sunlight onto the moon and remove it cleanly. The equipment there was all Metcal, and I was clearly told (as a software engineer) that I wasn't trusted to be within 4' of it :)

    Used Metcal equipment is not that expensive assuming you take your time to wait for a nice-price unit. I mean the RF generator base station, e.g.  MX500 and a handle.

    The soldertips are a bit pricey though.  Being the lucky b* I bought myself a life-lasting stock of new in box tips in Germany for about €3 a pop.  It is a box full, I admit to overstocking like a kid in a candy store..

    Probable need to mention them in my Last Will  ::)

    I'm waiting for my chance to get one here in China at a good price. I've saw some but cosmetically looked like they had been through a earthquake and back.

    Most I see being sold here are old equipment from factores that closed or got relocated, and most of them are cosmetically heavy used and with missing parts - most you can forget the hand piece.

    I will get one, I want to see why it is so well talked by everyone who used one.

    When I am salvaging unobtainium chips from a PCB, I put a Bulldog* clip on the top side of the pins. It works great as a temporary heatsink and gives you a lot more time on each pin without having to worry that you are frying the silicon.

    Both Iwatsu and Yokogawa digital scopes are very fine quality and specifications, easy to use interface.

    We had Yokogawa DL1520, 1740, 7440 since 1990s, highly recommended.

    Fowler digital caliper, mm, in, ft, new in pouch, excellent battery life, but plastic not metal....

     $5 NIB, at a USA CL contractor sale....

    Much better than the Chinese clones of Japanese mitutoyo calipers....
    The Fowler is sold for $50 on Amazon etc.

    Very useful and light weight

    Copper tape + Kapton tape + stiffener sounds like a solution to me; I will try it. Alternatively, you can try 0.8mm copper clad; it would be interesting to know the thickness of the original  ;)

    So does my Agilent 54641D. Given that one has a CRT, it is the CRT warmup that dictates when you can claim "it is up". No surprise really, the 68020 CPU is fast enough, and the whole firmware (I flashed it) fits on a single 1.44MB floppy disk.

    collected today - I anticipated that I would need a 1/4-inch collet, which proved correct.

    ... and the one I got of course wasn't suitable.

    On the bright side we make Makita's in the UK. - pity you didn't put a 1/4-inch collet in guys.

    [ed to add a photo]

    Robbing Peter to pay Paul - sorry Amazon

    now have the 1/4-inch collet, and my Prime account will remain closed for sometime.

    One thing Die Grinders with good Tungsten burrs are not subtle so more power and speed is what it is about >:D Plenty of lower speed and power more controlled options are out there for things like Roloc pads, buffs and grinding if needed.

    Other than that I brought two lumps of Swiss Cheesed Steel 2-4-6 Blocks in my 95%+ metric shop  ::) Over 8kg for the pair so good door stops if nothing else  ;D Yes you can buy this sort of thing in metric but for 'reasons' they are much more rare on Evilbay or AliX and come with a hefty price premium  :-//

    Copper tape + Kapton tape + stiffener sounds like a solution to me; I will try it. Alternatively, you can try 0.8mm copper clad; it would be interesting to know the thickness of the original  ;)

    0.2mm overall thickness.
    With regards to homebrew one: Including all the stuff like 4mm pass-through connectors, these are cheap.
    I already took great use of it measuring stand by currents of some gear. It is very convenient to slide it under the spring contact of a button cell.

    For my old Oki C5200, a black toner drum and from the US too as no one down under has them at any sort of reasonable price.  :scared:

    Darn thing had locked up all but solid inside and after some surgery found the rubber drive belt inside had broken and jammed up the gears.....that's what happens when you ignore the display warning to replace the toner drum !  :-DD
    Made an awful rattle with the nylon drum drive gears skipping and chattering away ........

    Need to use the networked family inkjet until the new drum arrives.  :popcorn:

    I have two ovals (one inside the other) that I've been using as a test track forever.  I'm building a computer interface with wireless hand controllers.  Started the design long before DCC was available to improve the slow speed startup of HO locomotives.  The design has PIC microcontrollers that output PWM for startup and slow speed and then switch to pure DC for higher speeds to reduce motor heating.

    My original computer interface was on an Apple ][ Plus.  It just couldn't cut it (5Hz 8 step PWM).    :palm:

    Now building a new layout:  I have the benchwork done and cork roadbed laid.  Just starting to lay the track.

    Looks nice. But... if the trains are going round clockwise it's possible to loop around and go anti-clockwise. But once doing that they can't then revert to clockwise. I think.

    Think you have a point there.

    Edit: Removed what I thought to be the solution, but it needs some crossover from the right hand loop back into the other loop, or a turn table some where.

    Nice hobby though. Here in Brive a thrift store owner also has trains as a hobby. Fairly big ones, but don't know the scale. Nice to look at for sure.

    The only way I can see to reverse a counter-clockwise direction is to pull-in, back-up and pull-out through the wye.
    Is that acceptable?  I don't know at this point.  I'm resisting changing the plan again.
    Currently, I have 5 locomotives that I can run short trains on different blocks of the layout. 
    So short trains run forward and backward might not be an issue.

    You could join DD to EE, forming a circle. That would give you an additional loop but also allow change of direction without stopping.

    Aaah you beat me to it. But it depends a bit on the minimum radius the track can handle.
    Title: Re: What did you buy today? Post your latest purchase!
    Post by: MarkF on September 05, 2022, 03:53:06 pm
    The minimum radius for HO is 18 inches.
    The lower right (from turn-out AA to DD) is a 18" radius minimum.
    The overall dimensions of the layout is 10ft by 7ft.
    The squares on the first layout drawing are 6 inches.

    You just can't make those turns:


    Anyway, this is getting far off topic.

    Also stocked right up on packs of 10 carbide inserts for my Harrison 12 lathe, 11mm boring bar TPMR110304 inserts, 16 + 22mm general turning inserts and a new parting tool .......not sure if it will be any good but it wasn't that expensive.
    MGEHR2525 with 10 carbide inserts.

    Oh and a SDS2354X HD scope on special order for a customer just in time to get it into our next stock shipment.  :phew:

    And another arriving tomorrow according to FedEx tracking is a dozen self sensing probes plus a few differential and current probes for stock.

    Here in the UK we have a saying:

    You wait ages for a bus & then three turn up together.

    It seems the same applies to the Datron 4910 voltage reference. I bought one last in July with a few Fluke 732A references for a fairly sensible price but mainly because the Datron is so very rare & I really wanted one.  This week I was at the same dealer looking for more toys to buy & found another two Datrons hiding at the back of a very dark store. Much more money changed hands & now I am the proud owner of three of these references.

    Neither are fully working, not exactly a surprise, but are fixable. One does work in that it powers up & produces 10V outputs but has a broken reset switch plus dead batteries. The other also has a broken reset switch, dead batteries, and at least one faulty power rail. The first one I bought is now working on mains awaiting new batteries that I am planning to persuade to fit in the next few days. All seem to be early models as the main PCB has a lot of modifications where the tracks were laid out incorrectly. Once my original buy is complete I will post pictures of what was done.

    It is still possible to find interesting & rare kit but it is becoming more difficult as time passes and much more expensive.  Guess I was just very lucky this time.

    Following a tip from Quinn Dunki aka 'Blondihacks' on YouTube I have been try some inserts designed for Aluminum. These have a higher rake angle and are sharper than normal inserts. For hobby use they seem to work well on my small 8x14 lathe. They are probably more fragile.

    I have bought and tested:

    DCGT070204-AK H01
    CCGT32.51-AK H01

    I have ordered

    TCGT16T304-AK H01
    MGGN200-G H01

    I should have these in about 8-10 days.

    It is the  'G' in the code, 3rd letter, that is important.

    3rd letter in the chart I've been using is insert size tolerance.  :-//
    Of course that's important for a programmable mill or lathe but for a manual hobbyist lathe ?

    OTOH G is significant for me as the 4th letter in the code is a principle requirement as it signifies double sided inserts and with T as the first signifying triangular inserts means double sided and 3 corners gives me 6 cutting edges for each insert.  :)
    You just don't know how satisfying that is to someone with Scottish heritage !  :-DD

    Although during my School times I had 2 calculators (A Graphics that I can only use in Maths and a Scientific for Physics and Chemistry - Casio CFX-9850G "Black Model" and a Casio FX-82MS) I got converted to Texas Instruments when I got the TI-89 Titanium back in 2005.

    No solar implementation on this one. For some reason I dislike how solar calculators design is implemented with the rectangle on top for the solar panel. If it was like the Casio "Tough Solar" or Seiko Solar style, were the panels are seamless integrated in the dial without being out of place it would be a different thing. Also chrome buttons... BIG HUGE NO! They are know for with time to break away and create a hazard since depending of the way it breaks out it can be a knife.

    Is the current Casio FX-991EX/ES or the Texas Instruments TI-36X PRO a better deal compared with this one? Probably, but I still like this one way more.

    Surprised more of the high end controllers wouldn't come with this, you'd think it would be a good selling feature: "guaranteed never to drift".
    From what I've seen on repair channels, they all come with the same "cheap" Alps pot units. Which I get on the low end stuff, as the clones are <50c each. No idea what Sony/MS pays for alps though.

    It would be but we are a minority. Most consumers just throw away the controller and buy a new one, they don't go to source the part and repair it.

    And companies know that. Extra profit by buying a new controller over a part that costs cents.

    Being inclined to mess about with old TV's, of the CRT valve powered variety, I'm always surfing ebay for parts, test gear etc, here in the UK.
    So, I wanted a particular Philips TV pattern generator and had an auto search set up on ebay. One came up this week, and it was local, like about 5 miles away, that is a VERY rare event for any item on ebay, let alone a niche piece of test gear!
    Obviously I bid for it, very strongly, and won it at £25!  Result right there!
    Being local I arranged to collect it and when I walked into the guys garage where he's kept it I saw the holy grail! Not the pattern generator, that was good enough, but 6 big plastic storage boxes full to the brim with NOS valves!!  All boxed, unused NOS!! there must be about 750 at least!! Then another box full of vintage NOS pots, presets, components, pickup cartridges, styli, etc, etc. I was literally beside myself with excitement!
    We had a chat and it transpires that his mates Dad had been a TV engineer and had unfortunately died, this was all his working stock. There was also another couple of test gear items which I snaffled, and there is apparently tons more stuff!
    We did a deal on the valves and I bought it as a job lot, it's going to be a huge task to catalogue them all!
    I'm getting first refusal on all the other stuff, can't wait to see whats there!
    He's quite pleased because it means he gets to clear a load of stuff to one buyer without having to list it all, pack it, ship it etc.
    I cannot believe my luck, it's just a crazy find, and local!  Going back to the Philips pattern gen, that is in fantastic condition, never been damp, no corrosion and cosmetically excellent. Amazing for a 40-50 year old piece of test gear!
    Still buzzing, please excuse the excited outburst!

    That is a pretty good find! Good luck with your sorting.

    I myself can be considered pretty lucky as well (perhaps not as much as you), but I was able to get a huge assortment of vintage IBM peripherals and SW and also a few interesting components - all for free.

    No, I wouldn't be able to hold onto such large item at this moment. Although there are several that pop in the local used websites in different functional conditions.

    As a kid I visited my dad's job a few times and marveled at the IBM Selectrics of the time. Quite the machines.

    1960ies Siemens Decade Resistor Box. 1R-1,22M from epay. Sadly as it turns out not in decent shape as the seller described it.
    Basically all but two decades where completely out of spec. Only the 1000R and the 100000R range were fine, all other resistors had drifted over 10% out of spec. On quite a few resistors the endcaps were loose so the resistance drifted with vibration, too.

    A total mess, I paid way too much for it. Have to take that issue up with the seller.

    But it looks so nice, I couldn't not spend 30,- EUR in new 1% resistors to make it all work nice again. Mind you original resistors were all 0,5% I'm not that crazy.

    I am just old enough that I chanced to try  one when I was a teenager and just starting to mess with computers. They were slow. Something like 11 or 15 characters per second but had an absolutely magical clunky yet precise mechanical action. I instantly fell in love. They (it) were being replaced by cheaper DecWriters and the occasional daisy wheel printer in the computer rooms I could break into though.

    Just got some delivery of some adapters that should help me conduct some nice measurements of power usage of some electronic goods- especially the dreaded minimum standby current of plugged-in PSU.
    Sadly, the Adapter Schuko->4mm jacks has to be returned, as one of the jacks is defective and the whole case is sealed/ultrasonic welded, so i cannot open it and fix it myself- a pity for some 45 Euro device.
    The USB Adapter to 4mm seems nice, I probably will report how well it goes in measurung USB voltage and currents- I hope to be able to verify some readings of those pesky tiny USB-testers with this.

    I bought this six years ago at element14 for AU$40 and now I want to buy another one, I have seen clones on Aliexpress for as low as AU$20, but I think I don't mind spending AU$20 more at Fluke Brand and free express. So I went to element14 to place an order and I was stunned by the price!

    They may look nice, but they're not good.

    These will not actually behave as a proper 0 ohm short, because the current from the force terminals will affect the voltage between the sense terminals. Might not matter on a low-end meter, but it will definitely be visible on a 7.5 or 8.5 digit meter.
    Take a look at how Fluke have done it (https://xdevs.com/doc/Fluke/5500A_EP_Short/RIT_2482.jpg).

    If you are trying to make some sort of point on thermal issues caused by heavier traces then look at the 4mm Bananas and almost certainly mismatched materials and try again  :palm: When you get into the weeds of 8 1/2 digits and under PPM so be it but then far more likely you would be not using bananas at all.

    Coincidentally, that minority that obsesses over expensive multimeters and metrology is the exact target audience for a 4-wire short. The vendor is also marketing the product as such (attachment below).

    Did some ballpark math based on the picture provided by the vendor. I estimate the short behaves as roughly 260μΩ when measured in 4W mode. This means it affects the least significant digit on a 6.5 digit meter with the lowest range of 100Ω, but more digits on more sensitive meters. My previous statement stands.

    Your 'estimate' is almost certainly wrong and is based on your conclusion then worked backwards to 'prove' your LSD attempted point. Last time there was a THREAD on this I remember it was in the 10's of nV with this sort of layout well below the LSD on a 6 1/2 digit meter.

    These are NOT aimed at the 8 1/2 digit crowd and by that show me anyone who is serious that is going to use Bananas in that situation for a start? Anyone with an 8 1/2 digit meter I would hope knows what is needed rather than attempting to underline in RED a portion of an evilbay listing. Try reading the Fluke link above as to what they consider a better practice. You might even learn something.

    As to 'shilled' seriously  :wtf: I offered a link to a 'good' alternate I have no idea who the manufacturer is and I have nothing to gain financially. Seriously get over your windbaggery!

    I mean, it's not going to be stellar, but it's an upgrade in quality of like to the Owon USB scope and the cheap chinese MiniScope I have.

    YeaPook 100Mhz (lol) Scope.  It's basically the same as the little tablet one that Dave reviewed a year or so ago.... but with physical buttons and dials instead of just touch screen.

    Seems the alt brand is Fnirsi.

    £180?  It might be worth it.  Cheapest beyond that is £350 for a Rigol.

    The error margin is ±20% at most, the estimate is definitely not an order of magnitude off. There is no working backwards or forward, either the number is right or it is not.

    The calculation is based on the resistance per square (the seller lists the PCB copper weight as 1oz./sqft). Based on the shape of the copper (counting pixels), I've calculated the resistances between the 4 junctions and from that, I've calculated the portion of the voltage that the sense terminals (right side) see when current is injected into the force terminals (left side), resulting in the resistance observed by the meter.
    You can start a new thread if you feel that this question needs a deeper dive (or if you feel like your hunch about my calculations is almost certainly right), I'll happily contribute. I'm done derailing this particular thread for now.

    Last time there was a THREAD on this I remember it was in the 10's of nV with this sort of layout well below the LSD on a 6 1/2 digit meter.
    The thread you linked talks about that number in regard to a bent solid copper wire short. That wire is also shaped in a way that current between the force terminals doesn't flow by the sense terminals, such as in the product that you've found.

    Definitely, a M.2 enclosure, looks to big to be a Msata... got a few just like it.
    usually comes in two M.2 flavors NGFF (next generation form factor 5Gbps Sata3) or NVme 10Gbps or above..
    you can usually see it on the socket and if it takes key-M or Key B... but check if there is an M.2 drive in it.

    Collection is coming together.

    10 pF ±0.5 pF mica
    100 pF ±1% mica
    1 nF ±0.5% mica
    10 nF ±0.3% mica
    100 nF ±0.3% mica
    0.5 μF ±0.5% x 2 polystyrene
    10 μF ±2% polypropylene
    100 μF ±3% polyester

    For larger values, the current plan is to use 10% 1 mF (1000 μF) tantalum SMD caps, which are still cheap. In series and parallel to get less deviation of capacitance value and higher voltage rating.

    You are now misrepresenting the OP on that linked thread to suit your argument. The OP produced a solid plate short and some of the feedback below from Dr Frank and others was that they saw no problem with it.What they did do was show some examples of what they had made using a single U shaped termination as one bit of wire is easier than lining up three and then relying on the solder joints to hold the Bananas in place.

    Your initial issue was with the 'resistance' of the short on evilbay but then please explain how this is an issue when the Fluke and others use 10mil traces with an almost certainly far higher resistance? The Reason for this is to reduce the thermal issues no more and no less and be of a sufficiently low resistance for the calibration process to work. If you bothered to read the fluke link and try and understand it you would see that Thermal issues play more of an issue with these than absolute resistance.

    Added to this that current flow across a wide short trace is not uniform but that is another whole can of worms

    Hi group,

    I bought a Leeds & Northrup 4286 Kelvin Bridge Ohmmeter.

    The bridge comes in a nice wooden box.

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1604584;image)

    It has five ranges from 0-1.1m \$\Omega\$ to 0 - 11 \$\Omega\$
    The stated accuracy is 2%, which is still pretty good today.

    Here is the schematic:

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1604590;image)

    It came with the battery, a No.6 1.5V Cell. It shown here next to an AA cell for scale.

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1604596;image)

    On the 1.1m \$\Omega\$ it uses about 15A!!

    I gave it a quick check and it is still within spec.

    Those batteries were still readily available when I was a kid.  I think they were originally used in telephones, but by the time I was on the scene they were used to power glow plugs in model airplane engines.  Hence the name "Ignition Battery".

    Hi,
    The galvanometer is a field replaceable unit. The instructions for changing the galvanometer are included in the lid of the instrument. If you remove the two screws on either side of the galvanometer the assembly can be lifted out. The magnet remains in the instrument:
    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1604953;image)
     
    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1604959;image)

    The electrical connections to the galvanometer are through the mounting screws.

    It is very sensitivity this with 10uA from a Fluke 5101 calibrator:

    (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/?action=dlattach;attach=1604965;image)


    The sensitivity doesn't matter, it is used as null detector.

    Similar galvanometers were used in other Leeds and Northrup instruments. Some were mounted upside down. I suspect that the galvanometer on my 4286 was replaced with the wrong version in the past.

    Got a Gigabyte RTX 3060 for $526 Canadian after tax. It was the last one on sale and I got it $10 less because someone returned it. I was not thrilled about that but there does not seem to be anything wrong with it.  Can't say for sure it was not used, but it did have the plastic wrap on the led window. The RGB led is kind of useless to me because I still use an old case with no window. I can't be bothered to get a new case so I take the lid off when I am going to full load for a while. That is also a Ryzen 5900X on a gen 1 Ryzen board a Asus Prime B350 Plus. I got the 5900X on sale for like $500 after tax. Mixed 2400 3200 ram. I run 2400 2400 15-15-15-35. One of the CPU fan leds died. Hope that isn't an issue. I am still clinging on to my Audigy2 pci at the bottom there. It goes to a gameport Microsoft Sidewinder.

    It's a Sartorius MSE2202 balance used from Yahoo auctions Japan, all told it was ~USD130 shipped which is a bargain considering these are in the $2k range new. Should clean up nicely I think they must have used the plastic chassis cover all its life (that has yellowed to hell).

    Display is easy to read, boot up time is only 5 seconds so that's not too bad. The response on small additions is excellent compared to a typical strain gauge balance.

    Trust me I wanted a milligram capable balance too, but analytical balances have much smaller weighing pans and you pay for the readability with lower capacity (e.g. 1ug readability at only 2g capacity for a micro balance).

    There is an upgraded version of the one I have that does do milligram at 2200g capacity, but they're extremely rare. (and this was hard enough to find second hand)

    This is as good a balance as I'll ever need for cooking purposes. Arguably overkill but when I need to measure 3.0g sodium citrate for a cheese sauce I know I'm good to a tenth of a gram. (tolerances for linearity is 20mg, repeatability 7mg, corner load 20mg @1kg)

    Yes I can just measure into smaller containers but god damn is it satisfying just chucking ingredients directly into a saucepan or mixing bowl. It doesn't solve the human error problem of over-adding ingredients but at least I'll know how much I'm off by... >:D

    A bit pricey for what you get, perhaps

    but it should complete my basic scope probe requirements (spree), which was [to remind myself]:

    a fixed 10:1 (100 MHz),
    a fixed 100:1 (300 MHz),
    two switched 10:1/1:1 (300 MHz),

    Haven't been around lately, who knows why, but I scanned the local craig's list and found a gem.  I've wanted an HP 70K MMS for ages, got pretty serious around the start of covid, again last February, and finally brought one home today.  I think this one was a steal at $1k.  I picked it up, brought it home and it seems nearly perfect.  Came with 70004 display, 70100A power meeter, 70310a Precision Frequency Reference for the time-nut in me, 70902A IF, 70900B local oscillator, 70908A RF Section and, drum roll....70300a tracking generator.  On top of all that I met a very interesting person that was running an inner-city center who had taken this and others as a donation.

    Forgot to mention, he threw in some nice 'N' terminated cables, larger than LMR400 and a power sensor, 8482A.

    Hope everyone is all well.

    Yup. Mostly outside of Japan/Korea/China/Hong Kong/Taiwan the min size is 0.5mm or 0.7mm.

    In those countries, because of how they write the size goes to as low as 0.2mm (Pentel Orenz Nero is an example of such).

    All brands sold in the west have always special editions in Japan of their products, or models exclusive to those countries (the Orenz Nero line up is Japan exclusive to the point that Pentel don't provide support in the west to those models).

    No oops. It's not their business at all. You should require them to give you a local (non-IT related) Ethernet port at your PC, so you can use the new scope properly.

    We got a new Tek 2 series scope at work. IT is upset because it has Ethernet and USB ports and we didn't tell them about it. Oops.

    No oops. It's not their business at all. You should require them to give you a local (non-IT related) Ethernet port at your PC, so you can use the new scope properly.
    Every company has their own idiosyncrasies and, although I understand the nightmare of having an unknown "PC-like gadget" with doubtful update/upgrade policies, IT departments sometimes forget they are a support entity and not the core business of a company.

    This is a case of "easier to ask for forgiveness than ask for permission..."  :-DD

    Maybe I'm missing something here, but the military memorabilia thread can be found... Oh wait, we don't have one because this is an electronics forum. I'm sure you are really happy about having bought this item, which I can fully understand, but what has it to do with electronics? I don't post pictures of the bag of potatoes I bought today for exactly the same reason. Can we keep our purchases on topic too please?

    Probably but so am I ;)  I have a Mitsubishi Evo 6 which I've owned from new, I must have £2k's worth of Ti fasteners on it and some custom fabricated Ti parts and a full Ti  Veilside 90MM exhaust.  Also have many Ti fasteners on my MV Agusta Brutale, want a Ti exhaust for it but it is many ££££££'s!!!  Ti and Carbon fibre are 2 of my favourite things.  If I could find Inconel parts without going broke I'd have those too!

    Todays haul involves some thermal grease (I will use to fix the damaged LED based grow lights I just got), some plastic tweezers from Knipex, some tweezers from Bernstein, opening equipment from iFixit and very nice, some cable conduct from Lapp: SKINTOP CLICK BS M 12- nice feature is that you do not need some countering screw on the inside of a case.

    The Bernstein tweezers feel very good, some soft, light touch on the metal and they will bend precisely, and the tip is not pointed, but made blunt as a chisel. I think I am hooked now, best tweezers I had in my hands so far, and for comparatively decent money.

    Well not exactly "buy today" but "salvaged today" instead.
    From a 55 in. 3 year old Sony telly with a smashed screen.  :wtf:
    Screen was damaged (not by me) when turning the tv against the wall.  :palm:
    These ever so thin frames do not offer any protection whatsoever. |O
    Thus beyond repair.

    From the PSU I only salvaged:

    4x N-MOS K4A50D
    2x N-MOS K8A50D
    2x N-MOS K15A50D
    and the heat sinks.

    All are OK. See graphs.

    Maybe I could use them for a simple electric load, should the need arise....
    [attachimg=1]

    I have a habit of testing any salvaged stuff before stocking it. No point is saving components
    of dubious condition.

    Sort of.
    Need to replace a satellite dish of a friend of mine at the weekend. The old dish is very rusty and the screws won't move in the slightest.
    So he'll get a nice new Gibertini 90cm dish as a replacement.  :)

    A small Function generator by Thurby Thandar, UK.

    2 MHz 20V, has Sweep input, DC offset and LCD can display F, V, DC offset etc.

    Was up for the bin at a lab, rescued, an unexpected gift!

    Exactly what I needed to complete my little lab in France.

    Anyone ever seen these?

    Final bit of a Laser Project I have been accumulating the bits for and now have some space to build in.  :phew:

    Outer Covers removed but fairly much finished design 1200x900 bed with pass through capability for rolled stock.

    First set of SMD components for the new PCB arrived.  Lots of pink and silver SMD bags.

    Got a fright with the crystal as it came separately with a load of documentation and certificates.  Seemed I ordered the "Certificate of compliance" version, oops.

    The STM32 MCUs came oddly packed.  Separate large bag with 3 bags of dessicant and one of those "bake, don't bake" cards.  Annoyingly though, the actual packaging was a small carboard box filled with anti-static foam and the 2 MCUs where just "tossed in".  With 64 LQFP pins on them, getting them off and out of the foam was a challenge to do without bending pins.  Took me 3 minutes to free one of them.

    Other than that I'm managing my AliExpress/Amazon breakout board and junk purchase habbits.  Although I couldn't turn down 50 WS2812 LEDs for £3.10!

    Bought a few items from the latest PP auction

    Weinschel 150W 10dB attenuator
    2x Leica GLS 100 lamps  - They're missing the light pipes, but I fished a couple of these from a skip a while ago. So all good, assuming the bulbs aren't dead in which case may be a waste of money.
    HP 8011A Pulse Generator - (sorry ICETEA) It's a nice little unit, will fit well on the bench.
    Narda 150W 3dB attenuator - I do actually need this to go between the output of my 2m radio rig and the input to my amplifier.
    HP 5326B Timer/Counter/DVM - I'm a sucker for nixie's
    HP8662 Sig Gen - Got a bit carried away, but I do like boat anchors  ;D
    HP8132A Pulse Generator - Spares or repair, this might be a nightmare/lost cause with all the custom parts inside. Hopefully not, otherwise you might see it for sale again !

    @RAPo: Megger output voltages are always way off and highly dependent on the load.

    I have two working versions of these vintage "crank Meggers". Unfortunately, many of them on offer on ebay are non-working, usually because some idiot saw a voltage scale and tried to measure voltages with them, which instantly destroys the coils. Inside they are extremely interesting though. They have hand wound resistors and the crank cogs are made of some sort of paper/resin mixture to isolate the generator from the crank handle. The case is usually a grained redish bakelite material which also looks cool for display purposes.
    But even non-working versions can still be used as a quick and dirty HV voltage source (if accuracy isn't important).

    They seem to be about £50 to £100 on ebay, so I still got it cheap. It's a shame someone screwed a nameplate into the front panel on that one, but hey ho.  I'm going past Aunby next week anyway on my way to Fluke, so I haven't got to pay shipping.

    Really you don't want one.

    I love analog function generators, lots of dials and buttons to push  ;D
    The PM5132 has excellent performance for an analog signal generator and it does 30Vpp which is more than most cheap function generators these days.

    The PM5132 has a short term drift that is at least one order of magnitude better than that of the PM5131. It's more like Tiny Tim.
    Of course you don't use this sort of equipment for stable frequency reference, but it's acutally not that bad either.

    I happen to have a counter.

    Drift over 500 seconds was 0,036%, which is well within specification.

    I also have a PM5193 it's the 'Big Brother' of the PM5131, PM5132 and PM5134. It has a drift that smashes the PM5132 by at least three orders of magnitude when it comes to stability.

    It's all good, but sometimes you just need to whistle or need manual pulse width control and in those cases I prefer good old analog stuff.

    The guage in these Meggers are a complicated arrangement. The needle has two coils pulling in opposite directions, comparing the current of the generator (across a resistor) to the returning current. Connecting any source to the meter will fry these coils immediately.

    I bought a McGregor mixer amplifier off ebay.
    Looked in good condition.
    However all volume controls were very scratchy and speaker jack sockets were in poor condition and not making good contact.
    It wasnt sold as spares or repair so I complained to seller.
    He refunded me and told me to dispose of it.
    It probably needs about £30 of components to fix it and maybe an hour or two of time.
    So basically beyond economical repair.
    I fixed the speaker jack socket and just use it in the house as its not reliable enough for gigs, pots too scratchy.
    It is a pig to get open and I cant see how to get front panel out as wooden blocks in the way of removal, so poor design.
    Shame as its a nice looking amp with front illumination.

    The Metrohm 7A501C Safety Tester (not really a megger)  have a wide voltage tolerance, see the instructions/specs.

    They are intended to test wiring and cables, for resistance between conductors 0-50 Ohms,  and to earth, and insulation resistance 0-50 megs.

    The load for voltage test is 1 M Ohm.
    it uses  a ratio so exact voltage is not important.
    Beware to use fresh batteries, the red rocker switch may need cleaning.
     I acquired two, at Paris Flea markets, EU 5 and EU 13!
    Reading  425V and 610V with a 1000V 10 M Ohm Philips DVM.

    Despite the voltage variation, both read similar R for  10M or ~ 1M test.

    Great units!

    What you have there is also known as a 'Engineers Scale' rather than a Ruler, Total Tools carries the Toledo range. Generally much thicker than the more common 150mm Ruler off evilbay and are square ended.

    The square wave looks more like you haven't calibrated the scope probe properly. It's relatively square, but the rise time is a bit slow.

    McBryce.

    Edit: just realised that channel 1 is on 1x which probably means that you connected the two via a straight BNC cable, possibly without any termination, so the wave is pretty much what one would expect. Try measuring the SigGen via a 10x probe with a 50R termination.

    Hi, I wish to share a non-purchase!!

    I ordered somethings from AliExpress, after 10 days I got a message saying that an automatic refund will be issued in the next 3-20 days.

    The vendor says that the item is out of stock, but still has it listed (999 available). There seems to be no place to leave feedback since the product wasn't shipped.

    I should get a full refund, but I have wasted 10 days waiting for the vendor.

    The vendor has 100% feedback, been on AliExpress for 5 years and 286 followers.

    Is this common practice on AliExpress?

    Other vendors I have dealt with have shipped within 24-48 hours.

    Ehhhh it's not uncommon.

    It depends if you're buying from like a manufacturers official store front or if it's from a "supplier" who just drop ships stuff from say taobao.

    They leave the listings up so it keeps the ranking for like SEO shenanigans.

    Hi, I wish to share a non-purchase!!

    I ordered somethings from AliExpress, after 10 days I got a message saying that an automatic refund will be issued in the next 3-20 days.

    The vendor says that the item is out of stock, but still has it listed (999 available). There seems to be no place to leave feedback since the product wasn't shipped.

    You can link the item if you want. Its possible they put the wrong price, or the cost to ship the item to Canada is too expensive, or it is actually out of stock temporarily.
    If you wanted to cancel prior to the 10 days, you can use the "Cancel Order" button. But yeah you'd have to keep on top of your orders for that.

    I've had the fake tracking number given a few times, thats more annoying than them saying its out of stock, because you have to wait to prove the number is fake.

    I got 2 ESP 8266 dev boards for $5 Canadian each = $10 no tax from a 'Kijiji' deal. I walked from my door about 15 min each way to pick these up. Still sealed with both male and female header options included.

    OK UPDATED: I soldered in the Arduino nano sort of headers and one I eventually got done but with some scratched solder mask. The second one I think I did industry spec. Maybe there was something different about the 2 solders (I have here) and I finally followed the video of adding the solder on the opposite side of the pin and iron. I just got the Arduino blinky working for one of them. That does not test the header just the built in led.

    I bought some banana plugs to make my own 4 wire shorts, copying Fluke's layout is easy, the only problem is that they use 2.5mm PCB, I plan to use two PCBs stacked.

    The PCBs were delivered this afternoon and I assembled one 4-wire shorts easily. Everything works perfectly except for the ugly silkscreened tracking number added by JLCPCB.

    When ordering from JLCPCB, you can select "Specify a location" for the order number, at the bottom of the quote form, and then in the very bottom, PCB remark box, tell them on which side you want the order number in, in simple English; say, "Order number on bottom, please".  I've done this to ensure the order number is not on the show side in my own designs.  It hasn't affected the price at all.

    Yes I know I can specify a location but I thought they would skip the silkscreen printing if there wasn't any in my design.  :-DD

    Yep, my parents, starting from nothing after WW2, do use all their equipment with uttermost care.
    They dumped an electrically dead vac cleaner after 25 years of use with a cable rollup in pristine order, because they never used the cable rollup to prevent it from getting worn. They used their 80s armchairs and sofa over 35 years and the furniture looked like new, when they needed moving to a smaller home. I had to dump it, because nobody, even the social shops, didn't want it for free because of the bulky 80s design.

    It's really scary to dump pristine looking very old stuff. Kind of a weird time machine going mad.  :scared:

    I like used thingies to reflect the use and to have some battle scars. 
    So please remove that protector and allow the PSU a start into true life.  :)

    Bought this little puppy alarm clock with radio. I was specifically looking for am alarm clock with amber or orange display, this one is perfect. The gentle orange large LEDs (or whatever this technology is) are not blasting my eyes at night when I wake up and look at it to check time. The best feature is the display is dimmable with a pot at the back of the alarm clock, I dim the display to very low brightness before sleep. The radio part is crappy but I do not use it, I switched alarm mode to buzzer. Also what is great it can display both the current time and alarm time. Not many digital alarm clocks can do that. The ambient temperature gauge is a bonus. :-+

    Also has a 2.4A USB jack at the back for cell phone charging, but to provide that juice the clock needs to be powered from a walwart. I do not use that and just run the clock on 3 AAA batteries.

    Somewhat different here in the US.  Here most devices I've seen are programmable for AM/PM or 24 hour system, but the cheap alarm radios only service AM/PM.  Well actually the coffee makers also seem to usually speak only AM/PM.

    Got annoyed trying to find dev boards for higher end STM32s and ended up taking a bit of a splurge on AliExpress junk after most sources either turned up the bottom of the bucket nucleos and a few stupid priced evel boards.

    I got a bit carried away and ended up with a checkout....

    An STM32H743VGT6 Dev board.  Interesting choice of putting 8Mb of external FLASH on it.  An SCard, a TFT header and a camera strip connector.  Not the first video focused board I've seen.  Not what I want it for though, it's to play with the chip.
    https://www.aliexpress.com/item/1005003989830214.html (https://www.aliexpress.com/item/1005003989830214.html)

    An STM32F407ZGT6 Dev board.  Similar to the above, lesser chip, but comes with some interesting adaptions including an NRF communications module.
    https://www.aliexpress.com/item/1005004389057711.html (https://www.aliexpress.com/item/1005004389057711.html)

    A STM32G030F6P6 Dev board because I have a thing for tiny micros.  They make good christmas/halloween light controllers.
    https://www.aliexpress.com/item/32828346568.html (https://www.aliexpress.com/item/32828346568.html)

    An STM32F405RGT6 dev board I probably added to the cart before I spotted the 407.
    https://www.aliexpress.com/item/4001016211320.html (https://www.aliexpress.com/item/4001016211320.html)

    2xF411 Black Pill.   2xF401 Black Pill and 2xF103 Blue Pills, because they were very cheap on the sale.  Might have got screwed on shipping though.

    Now I just have to wait on these all arriving on the snail mail.

    I think I got a fair range to try out.  I do need to answer a few questions on just how much / many audio channels and filters is practical with one or several of these MCUs.

    Oh and I couldn't resist a few odd sensors and SPI Flash modules and microphones and.....  you get the idea.  I'm £100 lighter but it was a fun bit of late night retail therapy ... in a few week I get a good few evenings of play if nothing else.

    Define what you need first then if any options are required as they can really add up !

    The 100 MHz 4ch X-E is good value but if you need more the 200 MHz 4ch X-E and particularly while the SDS2104X Plus is on special, not so much.
    You might come back with that's a 200 vs 100 MHz solution but it's not as the 100 MHz X Plus has a -3dB BW of ~185MHz.

    I don't need anything specialised, just general purpose, in round terms, 100 Mhz, 4 channel, with individual controls for each channel, largest screen possible for that spec with no fixed menu's on the rh side, so all of the screen can be used for signal display.

    Seems like you won't be getting a Siglent then unless you can get to grips with multiplexed vertical controls.

    Everything seems to be heading that way and TBH initially I wasn't a fan of them either but quickly adapted when sent SDS1104X-E back in 2017 as a beta tester to now I don't really give a shit is a scope has multiplexed controls or one encoder for each channel. Surprised myself how quickly I adapted too.  :o

    Much depends on how it's implemented as to what signals the scope UI gives you so to know which channel is active to the vertical control and IMO Siglent did a good job on that.

    Although the Siglent does seem to prioritise the waveform output regards display area.  When you switch off the menus and aren't showing any of the pop outs, it really is quite bare with just 85% of the screen being the wave display.

    Of course I haven't actually had hands on yet, so maybe I should remain a bit reserved :)

    Other purchases:

    1x  5x5Kallax shelving unit to replace the rather unbecoming plastic garage shelving rack I have in the office/lab.

    also

    1x  4x4 Kallax shelving unit which will sit on the rear of the electronics bench and provide a backdrop shelving matrix for equipment and close to hand supplies.  The bench is an Ikea work bench, it has a solid steel frame and the cantilever is only about 20cm, so I think it will be fine holding up a 15kg shelving unit.  If it gets dicey I can always support the table from below also.

    If anyone seen my post about the state of the office/lab has got to, I felt it was time to force my hand and buy furniture.  I can't leave them sitting in the hallway for long, so I have to tear the lab down, replace the storage and hopefully find places for everything and can form some clear work space!

    Christmas order to brother was a large anti-static, heat resistant, cutting work mat.  For lighting I am actually going to use a 100W LED white spectrum grow light.  It's a mix of warm and cold LEDs + some near IR that won't bother me.  It has a dimmer, thankfully because on full tilt it's like sitting under a cold sun.

    Anyone getting close to or beyond 50 will understand that eyes betray you.  I have actually found my main issue is sitting in "relaxed and subdued" lighting while fine for relaxing, REALLY puts a strain on your eyes when trying to work with small things like electronics.  I bought a magnifying glass with LED lights, but quickly found that mostly the LED lights helped even before I used the lens.  I mean I work normally by the light of the monitor screen and a strip of 2W orange LEDs behind the monitor.  So, utilising the unused super bright lights from the Pepper plant hobby that's paused due to the cost of electric, should help me eyes!

    Indeed that is true. Once the eyesight starts to go out, lighting helps quite a lot. A few years ago I got a good head loupe with three powerful white LEDs that made a complete difference even without the lenses.

    It's the focusing. A bright light reduces the iris size and increases depth of field. You achieve similar by making a small aperture between both thumbs and forefingers and peeking through that, but brighter light is much nicer :)

    Was going to say just that.  Same for screwing up your eyes to use your eyelids as a forced pinhole lense.  I'm sure every glasses wearer knows what I'm talking about trying to read your phone in the morning.

    EDIT: One thing I did spend about £7.99 on was a ring light magnifying glass, which has a handle that expands into a stand.  It also has an independant (non charging) USB input so you don't need to keep replacing the batteries.   It's great for quick "rewiring" a breadboard or a quick solder when it's not worth pulling down the bit magnifier light.  It takes up very little room and can be folded and unfolded with one hand, with practice.

    A Cuckoo Rice Cooker - after a second thought with amazon I went to another online supplier. These devices say 120V but I'll be surprised if I will have to use my uk/us autotransformer?

    https://longdan.co.uk/collections/cuckoo

    Says 240V on that site, for the one I checked.
    Its a heater coil, so you'd want the right voltage.

    A friend included this surprise Tektronix 2701 attenuator in a package of other parts via post.


    The vintage 2701 attenuator is 0..80 db 50 Ohms, uses the same thick film céramique attenuators and cam switches as in wideband scopes and plug-ins.

    1 ghz, 1.5 W rating . very useful and different than the HP attenuators.....

    your thoughts appreciated!

    Went to a Trade day at the local den of Tool Corruption who were offering 20% loyalty discounts toward my next purchase from todays purchases. Now what to spend these on  :-DD

    So "another" 5" grinder but this one is corded and variable speed for better abrasive performance and to stop chewing up my batteries in the shop also lower speed is way way better for abrasives. Getting hard to buy corded but for a grinder it makes so much sense as an everyday one. Wasn't that fussed about staying with Makita here like all my cordless stuff but Metabo has always done Sanding and Grinding well in the past.

    WEV11-125 Quick https://www.totaltools.com.au/98119-metabo-125mm-1550-watt-variable-speed-angle-grinder-wev15125?srsltid=AYJSbAc5CUZC8x5O5EvD1QrPk4yaX819prbsnkldbB9rIqaVnUC9K6QEWWQ (https://www.totaltools.com.au/98119-metabo-125mm-1550-watt-variable-speed-angle-grinder-wev15125?srsltid=AYJSbAc5CUZC8x5O5EvD1QrPk4yaX819prbsnkldbB9rIqaVnUC9K6QEWWQ)

    Also grabbed a 15W LiPo worklight (and BT speaker) for $30 AUD for the Aussie locals. Works great and cheap thing to add to the Car or tools. Powerbank capabilities, speakers and light so great value.

    endoscope 5mm diameter camera
    PC USB or Android phone
    y pay for more cable length & higher resolution as I understand it.
    also the 7mm  diameter cameras may run a bit cooler.
    however 360p at 1 Meter will do most jobs, whether its a peek inside car doors looking for rust , in-to engine spark plug holes,
    inside roof cavity's ,walls, body cavity's (veterinary or yourself at your own peril) it may not be waterproof.
    peeking inside electronics cases without voiding your warranty ( if there is a 5.2mm hole or gap in the case)
    when used the 5mm color camera tip got hot in just 2 minutes, so had to un-plug it for a cooldown.
    the LED lighting bezel runs hot.
    came with a handy 45 degree angle 5mm mirror tip. see image. also note- a good camera cleaning kit is also highly recommended.
    as the lens window will get cruddy quickly with use.
    just another set of cameras for my collection. I'm still on the lookout for a sub 3mm endoscope if its affordable.
    then I can assault ant hills & make cool electronics videos from a bug's perspective, tip for you Dave.

    @ jonovid

    Got a few of these. They are very useful in many usage.
    Good for the price but they vary a lot in quality, irrespective of the claimed specs.

    Some will last a few weeks when used at max illumination (overheat). Some have very low fps and need to held in place for a second or so the have a useful image. Some are not waterproof as claimed.
    You need to clean the front window to avoid reflections stray light from the led illumination but by the time you get to your objective the window gets dirty.
    Also look at the 45deg mirror as it might have a plastic peel-off that is matched to the mirror size and not readily noticeable in normal light.
    All worked well with the Win camera app, no need to download a dodgy app from an unknown source.

    Ended up getting a pro model that is incredibly superior.

    Mine from almost a decade ago is an Olympus CYF-240 endoscope with the video attachment that I got used.
    Now, considering  :scared: its prior history. That would mean a good IPA clean and autoclaving if you have a friend with one.

    As stated I got a lot of the cheaper ebay and alibaba ones for a LOT (a BIG LOT cheaper!!) cheaper but they never matched the Olympus for electronics use and hidden parts inspection.
    Another place to look would be used ones for the aircraft industry.

    If you order off AliExpress as a kind of sleeping pill to put you to sleep.  You buy one or two cheap things two or three times a week.

    It seems that AliExpress do everything they can to slow down your early orders so the later ones catch up to them at various "consolidation centres".

    The net result for me was about 15 different orders I had open ALL arrived in one large AliExpress sack this morning.  Lots of little envelopes to go through now.

    I bought a HP 3335A, don't know why but one of these just appealed to me. Decent resolution and flatness on these instruments. And a 75ohm output, which is handy as I already have an 8591C and W&G EPM-1.

    It's got the odd scratch, but pretty much mint condition, really nice and tidy !

    Fan is noisy, can hear it running wherever I am in the house. The rushing air I can cope with, the droning noise.. not so much.  May try a newer quieter one at some point. Care needs to be taken on CFM for these old units as they have quite a  positive air pressure in the case.

    Newport 350B Temperature Controller

    finally bought on of these. I would have preferred one with a GPIB-interface, but they did not show up for a reasonable price. So now, it is one with a USB-interface and I will have to find out how to send commands to it with linux. Hopefully a look inside for the chipset will give me some hints about the way to go.

    Talking to it succeeded the next day, listening to its answers took until day two. It was the first time that I used libusb. Code is still far from clean, but maybe it is interesting for someone to know that it is out there. Newport use their own Win dll for their usb-devices and this is of no use to me.

    Yep, did that. It is OK but I may have improved it (or not!) by including mixed peel.

    I think I've previously complained on here about the bird shit on my car that's resistant to a scrubbing brush and even a scraper. It seems they've been using this recipe - the advice to use a non-stick pan isn't in case it burns but because the thing is nearly impossible to clean after the glass-like film has set.

    Yet another STM32 evaluation board, I think this is the only cheap board with USB HS PHY.
    Teensy 4 is cheaper, and has two USB PHYs, both high speed (480 Mbit/s).

    Wow this looks interesting, except it doesn't have a real USB socket. And all Tenssy boards are out of stock in Australia. Maybe buy in the future, like Raspberry Pi Zero 2 W, add to my wish list.

    For a hobbyist like myself, it's a good platform.  It isn't really suitable for someone designing their own boards based on NXP i.MX RT106x chips, because the bootloader on the MKL02 chip on the board is proprietary.  (Except for general evaluation and testing of the platform.)

    Only one USB connector is soldered in (USB Micro-B, 5-pin); this one is also used for programming, no separate programmer is used.  One must solder the second one on; I recommend cutting a cable and soldering the wires to the pads.  Testing on Linux shows that even in Arduino/Teensyduino, over USB Serial, one can achieve well over 200 Mbit/s transfer rates using the main one.  I haven't tested the second one, nor bulk USB transfer rates, carefully enough to say how close to theoretical maximum bandwidth one can get.

    For development, I habitually use a cheap ADuM3160-based USB isolator (limited to full speed, 12 Mbit/s) off eBay, more to make sure my laptop USB ports won't get damaged due to my butterfingery than anything else.  They're all based on the application example off the datasheet, and the only real variance is the isolated DC-DC converter they use – some are more efficient, some less, but all limit the maximum current one can draw somewhat.  I'm waiting for the high-speed isolators based on TI ISOUSB211 and others to come on the market.

    PJRC does have some Teensy 4.0 (https://www.pjrc.com/store/teensy40.html) and Teensy 4.1 (https://www.pjrc.com/store/teensy41.html) in stock right now, 2022-12-30.

    For Teensy 4.1, I recommend also getting the PSRAM (https://www.pjrc.com/store/psram.html) (or two, 16 Mbytes of PSRAM is really nice for so little money), and the Ethernet kit (https://www.pjrc.com/store/ethernet_kit.html).  Also, on 4.1 the other USB port is available on pins, so you can use the USB host cable (https://www.pjrc.com/store/cable_usb_host_t36.html).

    The NXP MKL02 chip contains the proprietary bootloader and PJRC-specific Teensy stuff, and uses the JTAG interface.  PJRC does sell the pre-programmed MKL02 (https://www.pjrc.com/store/ic_mkl02_t4.html) chips, if one wants to make their own Teensy-compatible board.  Currently, suitable IMXRT1062DV*6B or IMXRT1062DV*6A chips are very difficult to find, though.

    The PJRC (Teensy) Forum (https://forum.pjrc.com/) is quite active, and Paul Stoffregen (creator of Teensies) actively answers questions there.  You can find his Arduino and Teensyduino code at his GitHub repositories (https://github.com/PaulStoffregen?tab=repositories).

    Thank you so much for your informative input! I've been using the STM32 lately, the last time I used an NXP MCU was the LPC1700 series about a decade ago. I like to collect a few (cheap) evaluation boards from different manufacturers just in case I need them, sadly most of the boards I get back are never really used, like those multimeters and power supplies.  :-DD

    Not purchase, but I finally got round to swapping out the office shelves.  Plastic garage shelving -> Kallax 5x5 180mmX180mm.

    The first page of instructions had a warning.  The first one was "Don't do it alone."  So since I'd already broken the first rule I decided the rest of the manual could be taken with as much respect.  They want you lay it out on the floor while you build it.  I don't have anywhere in the house I can lay out a 6ft by 6ft shelf on the ground!

    So I improvised.  Turns out you can build them upright just fine.  Getting the screws in the bottom requires something to jack it up with, it's HEAVY about 40Kg.  Your foot will NOT do.

    It definitely a lot more efficient use of the storage.  The 1ft x 1ft sub units fit most things.

    The next phase is clearning the bench and installing another Kallax 4x4 this time ontop of the desk as a backdrop for shelves, scopes, siggens etc. etc.  Leaving the bench theoretically "clearable" after a session.  We'll see if that happens.

    Have to work out what to do with the 3D printer.  It can't stay on the bench and wont fit in/on a kallax.

    Wouldn't use a Kallax for equipment, those things have an extremely low weight limit of like 10 kg per shelf and 25 kg on top. I wanted to buy one for the same purpose, but decided against it since it's basically a glorified cardboard box with a glossy finish.

    (1) the CPU does not even respond in debug mode.
    It's DIP, I have to buy a replacement on eBay.

    (2) the UV-EPROM was empty. I reprogrammed with BUFFALO/11.
    8Kbytes of ram isn't that bad for such a card
    uart wires were not wired to anything, I added a TTL-2-RS232 adaper.

    Scored this for the local equivalent of USD112. Bought sight unseen, although it's the older version, it turns out that it's almost spotless, with a display that looks brand new. Everything appears to work like it should, though I haven't properly put it through it's paces yet.

    Interestingly there are no cal stickers, or any evidence that there has ever been any. I can only assume that it's spent most of its life in a store room.

    This is quite a contrast to my usual purchases, which tend to require some panel beating to get them back into shape :horse:[attachimg=1]

    Bonjour à Tous, Bon Nouvelle Année!

    I have ~ Have 12 (!) handheld DVMs(!),  all old and inaccurate and/or cheap Chinese junk. And lots of Simpson 260, Triplett analog VOMs.
    My best is new  Keysight 34465a 6.5 digit laboratory bench-top. Hardly a field pocket DVM!

    Inspired by EEV blog,  researched handheld DVMs.
    Have Fluke electricians T5-600  clamp on, 1AC-AII, voltage hot sticks:    great quality, very long lasting. Considered Fluke 287, too delicate, display not robust, overkill for a DVM.

    Decided on  Fluke 87V industrial DVM, best value for a versatile, long lasting, error indication, backlight long bat life, beeper.  Current cat, USA not China, Fluke lifetime warranty is a big plus.
    On Epay several in auction, just  won ~  1/2 new price.....included  Fluke leads and yellow silicone bumper.

    Arrived, like new, leads still wrapped.  Great design, ergonomic controls, display and leak-proof 9V battery compartment.
    At CAL lab, high resolution,  4.5 digits, well within spec on every range, using best  lab standards for R, C, VDC, VAC, F, Temp,
    Should have bought the Fluke 87V  years ago!

    Next one will be the 87V MAX = IP67, super rugged, many extras….

    My highest recommendation! Your thoughts appreciated!

    Bon Soirée

    I just received a 'handy' Sencore "The Substitutor". It even came with its original packaging and paperwork. Inside it looks untouched and is suffering from only one slight problem  :palm: - somehow the retaining nut on the big old caps had come loose and those aformentioned beefy tubes had been 'flapping around in the breeze'. Unfortunately the result is a broken custom wafer switch and, as it stands, no more 'lytic range. I'm thinking superglue...

    Likely you can swap it with a standard wafer switch, they are not that uncommon, just have to get one with 10 ways from around that vintage.

    If it's standard then there's a good chance I can get something suitable from my local electronics components mall (shout out to Sim Lim Tower in Singapore), however I seem to recall from a YouTube video that this particular wafer connects custom assemblies of electrolytics in weird ways in order to make up the selected values... come to think of it, as I'll have to discard at least 3/4 the old lytics, it may make sense just to totally rewire that switch.

    Thank you for the hint. I would definitely agree for every 2001 or 2002 being bought, because it is a known weakness and there are many out there with severe damage by leaky caps. I also changed the caps in my 2010 to be on a safer side. But with the 2400 the risk seems more limited. I would guess comparable to other devices with electrolytic caps.

    I had a run of bad luck.

    First the STM32H750 dev board arrived from china after a month, containing an STM32H7B0.  Not the same calibre of chip at all.  No point sending it back either.

    Then I screwed up, twice.  I quick scanned for WS2812B pre-built light controllers which either came with WLED installed or could be flashed.  Found the first forum post saying that the SP108E hardware available currently on amazon worked with WLED.  So I ordered one.  It arrived and after opening it and going "WTF?", I googled it and it's a fiasco.  It has a TI MCU doing the LED control and the ESP8285 is only running their proprietary interface code for their wifi app.  You can get it to work, but it involves disabling the other micro and soldering about 8 mod wires to it.

    So I hunted the junk box and found an old controller that never worked, gave it one more go and... it worked.  So I jumped on Amazon and ordered 2 more, as I need 3 for a project.

    They arrived and ... FAIL.  Hit Buy Now too quickly.  I ordered the analogue RGB variant (4 wire), from the same manufacturer and in the same box.  I could return them, but they were like £7 each.  I actually have 1 or 2 RGB strips.  It's probably not worth the hassle.

    I just bought myself a DIY kit for putting solar panels on the roof. 12 panels that make for 4500Wp in total. Nowadays electricity prices are so insanely high over here that they'll pay for themselves in less than 1.5 years. If all goes well, the panels should deliver over half of my electricity use.

    No pictures yet; it will take some time before the panels are delivered. The only item that has arrived to far is a safety line (with a brake system) so I won't die from falling from the roof.

    tinySA Ultra
    The build quality seems very good.
    It seems to work good, but I have limited experience with spectrum analyzers. I also have a Rigol DSA815-TG Spectrum Analyzer which goes up to 1.5GHz.
    It's good fun for the price.

    Specs
    Frequency range
       100kHz to 800MHz in normal mode.
       Up to 6GHz with ULTRA mode enabled.
       The maximum frequency in ultra mode can be set to 12GHz with less accuracy.
    4 inch diagonal screen.

    More info and specs here:
    Wiki for tinySA and tinySA Ultra
    https://tinysa.org/

    I bought it from here:
    R&L Electronics - tinySA Ultra - $130

    Be aware of this safe place buying list in the wiki, or your are likely to get a poorly functioning clone which are all over the internet.

    Well I rolled the dice on an unknown condition Wacom Cintiq Pro 16...the bottom 25% pen detection zone is faulty (annoyingly that's where some of the calibration targets lie so now the stylus is off by 1-2mm). For ~USD170 I'm not tooooooooo disappointed, I'll just pretend it's a Cintiq Pro 12.5 ultra widescreen.  :P

    It's actually an absolute joy to use as the only other pen display I've tried is an iPad Air w/ Apple Pencil. This is much more precise and it's great to be able to use full desktop software. The fan is a bit annoying and it gets surprisingly warm even at low brightness (surface temp 35C in a 25C room after only 15 minutes). Sigh I've fallen in love with it already so I'm gonna save up for a new one, they're like two grand.  |O

    In my first job, far too many years ago, we received a shipment of 200/450 radial electrolytics, complete with metal mounting brackets.
    I chucked the metal bits into the parts bin, followed by the caps, only to be greeted with a series of large "zaps"! :scared:

    It seems the manufacturer tested them at full voltage before release, but this time forgot to discharge them!

    https://www.gl-inet.com/products/gl-mt300n-v2/ (https://www.gl-inet.com/products/gl-mt300n-v2/)

    I have a previous model of one of these with the antenna servicing the garage / garden Wifi items.

    Not bad, this one appears to have 2 radios or the chipset is presenting 2.  A 2.4bgn and a 2.4bg only.  So it would seem, at least without further research that it will be capable of proper Wifi bridging.  Assuming those radio interfaces don't mind being added to a bridge.  Sometimes you can't add a client to a bridge on certain chipsets.

    Anyway I only wanted it to patch a whole in the 2.4Ghz in the office.  For that it works fine.

    Also bought 5x #3 and 5x #8 for cleaning PCBs with isoprop

    You might find a battery toothbrush with oscillating head (https://www.aliexpress.com/item/1005001928662565.html) better for tight electronics (the brush linked there I have no idea about - it's cheap and on Ali). I use a Lidl clone of an Oral-B model simply because clone Oral-B heads are plentiful and cheap.

    Cleaning with IPA is more about dissolving stuff than brushing it off. Dissolve, soak up with kitchen towel, done. Washing off uses a lot more fluid, and you still need to dab with the absorbent tissue else the evaporating IPA will leave some stuff behind.

    I have the same set. They work very well coupled to a spectrum analyser that has a decent sensitivity. The two middle loops are the most useful.
    I would suggest adding a cheap broadband amplifier (powered from a 9V battery) to complete your RF snooping set.

    All measurements are relative but useful as go/no go indicators.
    That is how I identified a bad coupling capacitor on my R&S CMU200 and similarly a dead sweep generator oscillator on a Hitachi electron microscope.

    Have fun with it. Also note that Dave did a video about a similar setup a few years back.

    Nice, how are the cutters and jaw points on them?

    I got a set of Klien pliers as a present a decade or more ago.  They have one or two nicks in the cutter blades, but they will still cut a human hair in the undamaged parts.

    As a test I once put a cigarette paper and a motorcycle clutch cable into them at the same time and it cut cleanly through both in the same closure.

    Their jaw points don't actually meet, which I thought was a design oversight until I used them to strip cables and went, "Ah ha!", not a mistake.

    It's amazing that any big product like that could have such terrible thermal management and monitoring that it would ever allow it to get hot enough to reflow.

    Nice, how are the cutters and jaw points on them?

    I got a set of Klien pliers as a present a decade or more ago.  They have one or two nicks in the cutter blades, but they will still cut a human hair in the undamaged parts.

    As a test I once put a cigarette paper and a motorcycle clutch cable into them at the same time and it cut cleanly through both in the same closure.

    Their jaw points don't actually meet, which I thought was a design oversight until I used them to strip cables and went, "Ah ha!", not a mistake.

    The Pliers are a hardened set (harder than the cutters) and the jaws closer to the hinge have a small gap but across the main part are tight. Cutters engage at the tip first with no pressure and with light pressure (blurry shot  :palm: ) close up perfectly so they are 'currently' uniform until I do something nasty to them  :-DD

    Engaging at the tip first makes sense if that is intentional  :-// as the finer part will be easier to flex than the rear fatter part to get a full flat cut.

    This is a little too easy...

    I think so, too :)

    It seems to me you are buying at close to the price of working consoles (at least, that's what they are here in the UK), and it's those you will be competing with once you have the things working. But you won't be getting that price, even you sell them at that price, because Ebay will take their cut and your payment processor will take their cut, and there is shipping on top. If you can make that work then it is a cool way to get some new toys, but I think it best to wait until you've actually got rid of the stuff before celebrating.

    I don't want to put you off and think that any attempt to make a go of things is great, but one has to be realistic at some point. Perhaps there is a market for 'professionally refurbished' machines that are a bit more expensive than generic used ones. You might have to wait a while for someone to bite, though, and of course the finish would need to be very good.

    When you close the box the stylus impinges on the roll of paper which appears to be like carbon-copy paper. So theoretically if you found the right kind of paper you could turn it into a longer-term temperature chart recorder.

    Engaging at the tip first makes sense if that is intentional  :-// as the finer part will be easier to flex than the rear fatter part to get a full flat cut.

    After I posted it dawned on me why the jaw points don't meet.  It's so you can re-surface the cutter blades.  They only meet at the cutter blades, so if you grind them back to sharp and lose 0.25mm of cutter blade, they still meet (if machined well).

    Part of the issue with a regrind is you need to make that in reference to the pivot point rather than blade to blade or you will screw up the geometry. So a tip heavy grind will be needed to keep them tight when closed.

    I would stick to a jig saw for cutting most stuff, better control if you work out the fixturing. that one looks dangerous as hell, with no 'gun' style grip on it, and it does not look to have any guide rails/base, which is dodgy for a sawzall type tool. I see some of them have a 'sten gun' saw guide, which I also do not like but its better then nothing.

    I totally hate those tools for anything but something massive like cutting a hole in a car (airplane?) body, always vibrates way too much and its hard to fixture, the jig saw base acts like a decent damper against vibration at least. auto nibbler not better?

    Fnisri SG-004A

    Was looking at the much cheaper SG-003, but the 004 has more features and, at the time, was on special offer. I previously acquired a Fnisri 2031 mini scope and thought it a bit rubbish (manual triggering is restricted to 10ms/div range or faster, weirdly) so was a bit apprehensive about the 004. I think it must be someone elses badged kit because, despite the lack of English-speaker's proofreading of the labels, it's actually pretty good! The user interface is, er, 'interesting' and needs a good perusal of the manual to get it to do anything, but it seems reasonably accurate on input and output.

    One of the interesting things you can do is conversion between input and output. You can, for instance, set the input range of, say, 1V to 5V (4V span) and have that drive the output range of, say, 10ohm to 100ohm (90ohm span) and it will do it perfectly. Any of the input modes can be used to drive any of the output modes, so knocking up a quick test rig should involve less messing around than normal.

    Edit: In case you're perhaps wondering what this signal generator actually does, anywhere else it would be called a process calibrator.

    Just got my hands on some interesting toys. German company ELV has some nice system for breadboarding with ready-made component holders that have SMD parts soldered on the underside- and big pins to ensure good contact with the board. Also the supplied board seems to be of very good quality. And there is a platform for breadboards, where there are some external power connectors, pots and probing points for multimeter or scope. Is nice, because I can now use 12V lead batteries or similar stuff to power a circuit without the need to adapt too much stuff to the connectors.

    Oh, and finally some spool of Felder SN100Ni+ (Fuji pat)in 1mm and some small probe (1 meter) of Felder SAC305 1mm, so I will do some shootout which solder I like best.

    Fun fact: Ordered in germany with a company that gave me a very good price and acts mostly as a simple mailorder operation, whilst on the solder itself there was the sticker of a well-known company with its own online shop operation, lets call it big "C"- but they sell for nearly 13 Euros, I got my roll for 10...

    this PCB is part of a kit that you have to finally assemble yourself- because 1) I would save some money on this, b) I get to brush up my under-average soldering skills and c) the manufacturer is big on kits here in germany

    If you have the floor/shelf/bench space for them then the Scroll saw is a great option if you want to do anything NON STEEL so FRP/PCB, Aluminium, Brass, Copper, Timber or plastics etc they are great. Mine is stuck in a container but I would never not have one given the space and mine is heading out of storage soon with a revamp of my shop. Drill a small 3-4mm hole is plenty to fit the fret (range of TPI for different materials) blade and the cross pin on most of them for inside shapes. Set a fence for straight lines if needed for longer runs.

    A new batch of all stainless orthodontic stuff.

    Extremely useful as they provide unconventional functions in unusual situations.
    Cutters have carbide inserts. Hemostat fits well in your hand when soldering strings of LED and holding small stuff andis easy to unlock. Hook plier is superb to work on small connectors like BNC or SMA.
    Top one can bend stiff wires to small radius and rechape connectors.
    Keeping on the dentistry theme I find my old ultrasonic descaler (not shown here, like used by your hygienist while cleaning your teeth but without the water!)  very handy repairing smd pcbs to clean the components and damaged traces.

    I've never used breadboards. With soldered prototypes I can store
    these away (properly labelled and documented of course) to
    return to them even years later.

    Usually you don´t use breadboards for complete protoypes.

    Was going to DIY up an amp and reuse previous speakers passively, but it turns out just as easy and not at all more expensive to just replace them with new active ones.... with optical and no shared grounds!

    Because some aren't properly grounded, some are incorrectly wired at the power cables and some have a metal heatsink sitting directly over a mains trace (the last one is from memory, so may not be 100% accurate).

    The OP looks like a more reputible unit.  The 858D clone I bought has an issue where the fan slows down if you hold the handle upside down.  It's probably some horrific wiring thing, I really should check.

    But yes, various models have been opened on live stream to find things like the neutral wire going through the switch and fuse and the earth conductor not being connected at all.  Making the thing a shock hazard with a live "live" when it was switched off and no ground if that live should ever contact the metal interior of the blower handle.

    More of an annoyance, but can be serious.  A lot of them have switch mode psus with 100VAC floating grounds, not a big issue, but annoying.

    Apart from the wiring issue that was mentioned there are other things to check.

    Your unit looks like a better quality than many others but I would do a quick check just to be sure.
    Look at the top video in this posting:
    https://www.eevblog.com/forum/chat/electronic-workbench-fire/msg1700225/#msg1700225 (https://www.eevblog.com/forum/chat/electronic-workbench-fire/msg1700225/#msg1700225)
    The unit just started by itself and obviously has no thermal shutdown if it overheats.

    I have a cheap one and the "on/off" front switch just activate a TRIAC that is on the mains at all time. This provides the power for another timer circuit the fan to cool off the tip after you press the off switch.
    So, in the middle of the night a mains power transient can damage the TRIAC and power will go the the heater with nothing to stop it.
    I then rewired a real of/off switch on the front panel to make sure OFF means OFF.
    I would take a quick look to make sure it is the case for your unit.

    Image 1 and 2 are the TRIAC and the mod.

    So I have had one of these cheapy Multifuel MAPP/Acetylene/LPG Oxy Torches on my evilbay watch list for a long time. Helpful seller sent me an offer that was about the price of a dozen ok beers so I decided it was time.

    (https://i.ebayimg.com/images/g/6xYAAOSw-e1es8bh/s-l1600.jpg)

    Then I needed to spend around the price of 5 boxes of Beer buying the rest of the bits to properly use it including some 45% Silver Solder etc.

    (https://i.ebayimg.com/images/g/K1cAAOSwryBgRonh/s-l1600.jpg)

    What a bargain Torch at least  :-DD

    Not an essential for most EE's but playing with small bore tube, Brass and Copper sheeting etc just the thing rather than swearing at a junk MAP/LPG/Butane Burner. For me it will also see use with Carbide tooling among other non EE things

    I got the "ultimate" breadboard from ELV, highly recommendable..
    With LEDs, trimmer, switches, pushbuttons, even a small squarewavegen upt to 100khz is included.
    I take your ELV and raise you my new-to-me Knight ML2010 Mini Lab...  These are all over eBay and while most of the time ridiculously priced if you keep any eye out you get get one pretty reasonably.  I got mine for about $120 including shipping.  The ML2010 is the 'big' version, they also have a smaller ML200 that omits a few options.

    The one thing that is annoying is because these were designed for educational use in schools, the lid is fixed to the case and only raises 90' straight up.  I'll have to come up with a solution to make it removable.  But it's also nice to be able to close it up and stick it in a closet when not in use.  And because it was designed for educational use, it's built like a tank.

    I have a real Oxy-Acetylene set packed away in the shed.

    When I first got it (actually, the one this set replaced after someone stole the original) I was a real "oxy moron", finding uses for it everywhere.
    Over time, as the occasions when it left the shed became fewer & fewer, & my eyesight got worse, I rebelled at "signing my life away" to BOC for bottle hire & returned them.

    More recently, I had Cataract operations, got my eyesight back, & have toyed with the idea of putting it back into service but have jibbed at the price of flashback arrestors which seem to have become mandatory in the meantime.

    I might need new hoses too, so it is pretty much a "pipe dream".
    In the end, I will probably end up flogging it off at a Swapmeet.

    In 50 years owning a gas set never used flashback arrestors and if you have any idea of what you're doing there's no need for them.
    If you don't follow normal operation settings/pressures then you might.

    No real 'need' for Flashback arrestors but not a bad idea and not a huge cost these days. At least these days we can buy the bottle rather than hire them which pays back quickly over a few years instead of BOC extortion when they were the only game in town.

    Unless you want to cut stuff up a high flow LPG Rosebud (for heating) and a smaller torch like this one will do most of what you need (we had a few similar sized ones among the class set with standard ones in school 30+ 40+ years ago (forgot I am that old  ;D ) for silver soldering and even fusion welding with Acetylene). For chopping stuff up Plasma is likely cheaper if you already have a decent compressor too.

    Likely if you put up what you have on evilbay you would get the same sort of $ I spent on the disposable bottle kit if you only fire it up a few times a year.

    oh for christ sakes just buy some hose and arrestors and enjoy the fire. Its like giving up on your drivers license or ability to eat solid food >:(

    I even wanted to buy the crimp tools and stuff to make my own hoses so I can select the optimium hose for the work area. I don't know why people don't feel that the hose for the torches is any different then nice multimeter leads. You can even probobly put a braid over the hoses to make them look nice and have abrasion resistance, so many options to choose from. I polish that equipment too and scrub the hoses clean so they look nice. Or to have a manifold setup with different torches ready to go. For some reason some people seem to pinch pennies on this stuff, but its so capable and there is alot of engineering you can do just around the gas distribution system to make it nice and usable.

    For instance
    1) braided/protected hoses
    2) gas distribution manifolds for multiple torches (standard, rosebud, cobra, smith mini torch, oxy/acetylene, air/acetylene)
    3) quick disconnect
    4) auto ingniter/fuel saver
    5) torch holders
    6) reels
    7) hose holders that reduce weight on hands while working
    8) torch assist holder arms (think smartgun from Aliens), I thought its possible to make an arm to help you hold that torch steady while you are working on it for a long time
    9) actually figuring out thermal shields that work
    10) all the stuff required for deep cavity welding/brazing (extensions etc)
    11) optimal flux choices
    12) heat focusing stuff (special cut firebricks, holders for them, etc).. aids in gas management/weld time
    13) experiments with visors/eye protection involving optimum visibility (wow, the stuff about aluminum sodium flare and the lens choice is just all over the place, going into audiophile territory).
    14) fixturing, endless
    15) exotic brazing (titanium for instance), new world out there.

    Huge world of possibilities. Hard to get any of that stuff right though, but there is no reason to think that acetylene ends at caveman desperado HVAC guy operating from a rusty old chevy van, or metal scrapers that have atomically thin margins. I feel like 95% of the content out there about acetylene is fouled up by budget independent trade workers considering cost only... well this is electronics buddy, we are not interested in how many chinese food soft serve ice cream machines and hotel ice makers you managed to service for 50 cents... how about exotic RF parts otherwise unavailable.. the majority of people talking about acetylene see it as a "solution" not a specific method or capability.

    nah the nice hoses have a hex crimp on them like a coaxial. Those kinds suck for hose you have to handle.

    But its a bit over kill , because you can have the guy in the weld store make them. Not a bad idea to ask, they are yearning to utilize the skills learned in welding engineering & technician school, rather then using a bar code reader on a blister pack. The good stores have tooling so you can get custom lengths made up. Not worth trying to get rid of the middle man there because you don't need alot of them and the tooling is kinda heavy.

    Mine were crimped in the weld store 8 years ago and I have 0 problems.

    Yeah but using those above you can easy do yourself with end nipper/nail pullers when old hoses fray and leak near the torch. Although one line is flammable they are very low pressure and therefore easy to contain with hose crimps like those which are available from any good engineering store.

    My Chauvin Arnoux 1-10 ohm Decade Resistance Box has just landed - my initial disappointment is receding .

    It's educational equipment, with something of a retro design. That to me looked better in the brochure than it did out of the box.  :palm:

    I haven't posted in this thread before even though I buy all sorts of random stuff, but this was too good to not mention.

    A Tektronix P6015 20/40kV probe, new in box with a full can of dielectric freon.  What are the odds of finding that?

    Nice find!
    I was lucky like this before as well and still have two full cans of FREON.
    But this is extremely rare these days.

    The FREON filled probes have the benefit of higher voltage rating and it makes the probes repairable.
    I had a broken P61015A that is gel filled and it was near impossible to peal out the gel and repair it.

    For special applications like this, we should still be able to buy FREON.

    I remember my first foray into being a TV studio Tech (actually a trainee at the time).
    I was told to clean the gate of a projector, & given a brush & a shallow bowl of liquid freon to do so.

    The freon evaporated quicker than I could work!
    At the time I was so concerned with doing a good job, I didn't realise that it was their equivalent of sending the apprentice for a "long weight". ;D

    JST crimping tool.

    Happy.  I was quite surprised at how reliable and effective the crimper is. 

    First thing I did was make male dupoint, then female dupoint, then steel pin breadboard wire...  UART leads for my FTDI quad UART.  It's such a simple quality of life up, but it's awesome. 

    I'm sick and tired of DuPoint.  The make a brilliant connection the FIRST time.  Every time after that they just get looser and looser.  After about 10 disconnects/reconnects the just stop gripping.

    Actually my main bug bear with them at the moment is when mixed with steel pin breadboard jumpers, the dupoints push the breadboard jaws open far enough to cause bad contact with the jumpers adjacent to it.

    Wrong forum, but is there a reliale way to tighten up dupoints?  I have tried pinching the exposed metal bit with pliers but it doesn't really work.

    Device is in good condition, and after about 50 years, some sticky plastics inside.
    I think i will clean it a bit and look for oxidation,  but even yet the pots seem to work nice.
    Interesting: With voltage knob turned totally left, I measure -0.6 Volts  on the output...

    I've seen a very small negative output on a linear PSU before, I believe the issue is the setpoint goes to zero, and a small offset in the control loop (usually powered by a bipolar supply) biases the base of the pass transistor quite negative. So then the leakage through the BE junction pulls the output very slightly negative. If you put anything more than a tiny load on the output it'll roll back to zero, so it's not an issue in practice. Also there's usually a reverse biased diode on the output which will clamp the output.

    I have one of these, very nice unit with excellent build quality for modern stuff.  Bought it at an MOD surplus sale many years ago, it was mainly for machinery so no one knew what it was, therefore I got it for the £10 opening bid!  I suspected it could have been faulty but it worked perfectly.

    No problems with it...
    Unlike other models it´s with an adjustable headband that works really good, no pressure on the head.
    The pcb holder is coming with a solid metal base plate and the arms are flexible in every way.
    It´s so stable that two arms would be enough to hold a small pcb.

    My first "boat anchor" (not really). It's a university lab isolation transformer. Got it from a flea market. There is no signs of model indication or anything. There's only an inventory sticker on the back saying it's from University of Twente.

    I long wanted an isolation transformer. Could have made one myself, but I spared the effort. Didn't really want to buy it. I just talked with the seller, hoping he would put an unreasonable price tag (Dutch people like this  :'( ), but he said I could have it for 10 euros. Couldn't resist that.

    The unit is well built and preserved. The only thing I don't understand is the purpose of the diode. I opened the enclosure, everything looks nice and tidy except one screw connecting the indicator lamp on front panel. It was loose, that might explain why the first time I powered it it didn't lit up. The tranny seems to be 48VA, made by AMROH (Holland), part number 36.251 . There are additional taps of 2V and 4V which are not connected to the front panel. The box could've made smaller. But, I guess, bench space was no problem "back then". Though I don't really know how old the device is, can't see any date codes.

    When I think of 'isolation transformer' I tend to think of 1:1 mains isolation, but certainly that isn't a requirement.

    Is this device possibly some kind of power supply?  Wouldn't the diode provide 1/2 wave rectification from the various voltage taps?

    Yeah, I think it's kind of lab power supply. About rectification, wouldn't 1/2 rectification create a DC bias, which is bad for the tranny (and mains)?

    Not exactly "bad"... But more ripple, poor power factor, and not as much useable power as a fullwave rectifier would give you.

    ::) That it is not !

    Instead it's a plain and ordinary 24V multi tapped mains transformer as easily seen from the labeling on the transformer secondary side taps configured for use as a multi voltage lab AC PSU.
    48VA suggests it's 2A rated at 24V which is just enough if bridge rectified, smoothed and passed via a linear regulator to provide a 30VDC output.

    Maybe the test was to find how many mains cycles a 1A diode could survive into high loads as it seems it was deliberately configured as easy to replace.  :-//

    A Prof I know got students to see if they could get 20A through a 1N4148 and succeeded at some microsecond  frequency I cannot now remember.  :horse:

    4 105Ah LifePO4 cells.
    Another 4 105Ah LifePO4 cells.
    A dozen different electronics component kits of ali.
    Heavy duty crimper for battery terminals and 10AWG wire.
    Rachetting crimper for normal blue,yellow,read,grey crimp terminals.

    Too many small projects, especially the ones requiring drop of £100-200 per item.

    I have a list for the next month too.  Likely won't be saving much this or next month.  Hopefully I can at least start to make a few quid back (from the solar).  It's already looking like a theoretical pay back of "up to" (brilliant marketing term) £100 a year, or 5 years ROI.  Reality is more like 50.

    Just one panel ?  :-//

    3 we installed to power a remote data transfer installation are already past 1.5 MW after just a couple years.  :o
    Your charge controller can handle 4 at a pinch but 3 panels would be more conservative/safer.

    Not today but in the last week
    Long time away but getting back into everything after traveling all over the country for work.


    The SA was to good to pass up at $330 Yankee bucks had align now align all error but no unlock and the clock was all wrong so took a chance it just needed the battery replaced and all is right in the world now once it has the backlight is replaced.
    The counter was buy it now for $40 so thought I would take a chance as my only other one stops at 100MHz and it works.
    Hooked to my leader sig gen and they both match as close as I can tell with my counter on my tm500 mainframe and the hardware counter in my tek 2467
    Also have an HP437b coming was $49 and lister said it passed self test so decided why not.

    Several lb's of unobtanium (locally or ex Asia) Copper and a little Hafnium from an unhelpful US supplier who after 3 messages over a week couldn't be bothered replying as to shipping the other two items in theory not shippable to Oz because 'reasons' unlike the third which they already in theory allowed :palm:

    Did a little due diligence in what seems to be a complete Snake Pit of on forwarder services which seem to vary from gangsters and standover merchants to spinning the wheel of non delivery and black hole shipping :o

    Final result looks like I will about break even on the numbnuts listing postage price and the items (paid with Paypal) have left and are headed to Stackry who also takes Paypal for a little extra security. Because also for 'reasons' internal USA shipping was 'free'.

    Cheap and nasty (except it isn't) calculator:

    https://www.aliexpress.com/item/1005004974428274.html (https://www.aliexpress.com/item/1005004974428274.html)

    Seems to work fine, and the stylus needs wrestling from the case (a change to having them spontaneously eject and get lost). Only real problem is that the 2nd function legend applies to the keys below but is printed right up against the keys above. Takes super-human effort to remember to press the other key...

    Anyroad, got this for the garage where I didn't want to trust a decent calculator to fate and/or a ham fist, and the sketch pad seemed like it might be useful for reminding one what the calculation is for.

    How does scatchpad work? Is it really an lcd screen, or it's a purely mechanical thing? Can you please share a real photo of the scatchpad in action?

    It's not an LCD - I think it works on the same principle as an Etch-A-Sketch (that is, it's an electrostatic screen). And just to confirm that I took the battery out and could draw on the screen, and, as expected, the button didn't erase it. So the battery appears to be only used to erase (the E-A-S equivalent of shaking it inverted).

    The stylus is only there to prevent you using a sharp implement (like an real pencil). You can draw with a fingernail, but the stylus has a decently large radius to prevent scratching.

    Yes, you can still draw (rather, erase it) when the calculator has died. Or vice versa. Solar power would have been nice, though.

    The hinge might come apart, so could be useful having the two parts separate. The two batteries would allow that, but I bet it wasn't designed for that possibility.

    How is the contrast? I've watched a few videos on such writing pads, and they all looked dim to me.

    Yes, a bit dim. Well, non-contrasty. And it depends on how hard you press (presumably how thick the line ends up as, since it has no gradient). The screen is matt reflective, so the sketch can be washed out by your overhead lights if you hold it wrong. Other than that it is very much like eink, except lime green on black.

    Oh, viewing angle isn't too hot. Probably about 120 degrees or so for the full effect. Frankly, I wouldn't buy one of these screens by itself if only because you can't selectively erase (or undo). But as an adjunct to the calculator to, say, jot down a series of results or whatever, it's a useful gimmick.

    Chinesian day, so enabled by some other forum member and the small price, I've got the ceramic screwdrivers, sadly, in the set are three flat and one Phillips, but I'll hunt for a square and hex as well and maybe a star:

    also when I was ordering the screwdrivers I've seen some wolfram tipped scratchers, and I've got two for a song:

    They're absolutely BRUTAL, the tip scratches everything I've tested with, from an old sapphire watch glass, to a real chrome-vanadium tool, PCB and other stuff is like butter.

    Purchased another bit of "Fakita" tm garden kit. My baby 4" (brushed) one I got 18 months ago is still going great but I have two or three larger bits to chop. The Blower (brushless) I got 6 months ago is doing well so time to go for something that can really do some personal harm  :-DD

    Only 12" Bar and I would prefer some sort of anti kickback protection so if you buy one play safely or just don't buy one if you haven't used a chainsaw before. Also not a thing to chop down a forest or firewood for winter but for the odd larger stump in a garden should be more than up to the job.

    Goot are a well established Japanese brand - I wonder if these are original or fake? Seems like a strange thing to bother counterfeiting. By coincidence I just received a set of Philmore trimmer tools from Amazon US. I wasn't able to find the equivalent tools locally or on AliE, and the Amazon price seemed reasonable. The set seems to have almost everything except the 'screwdriver' type tips, so would make a good complement to the set you bought... in fact, I think I will put your set on my next AliE order as I've only got one ceramic trimmer (the one that looks like a chopped off phillips).

    The 'scratcher' looks good. In English it would tend to be described as as a tungsten scriber, not really sure why we dont call it wolfram, especially given that its technical symbol is W.

    History
    In 1781, Carl Wilhelm Scheele discovered that a new acid, tungstic acid, could be made from scheelite (at the time called tungsten).[39][40] Scheele and Torbern Bergman suggested that it might be possible to obtain a new metal by reducing this acid.[41] In 1783, José and Fausto Elhuyar found an acid made from wolframite that was identical to tungstic acid. Later that year, at the Royal Basque Society in the town of Bergara, Spain, the brothers succeeded in isolating tungsten by reduction of this acid with charcoal, and they are credited with the discovery of the element (they called it "wolfram" or "volfram").[42][43][44][45][46]

    Being a bit of a vintage test gear nerd, I scored these beauties which arrived today!!

    For new players and those that are not familiar with UK test gear brands, these are the legendary Avo 8, possibly the best analogue multimeter ever made.

    First pic is the Mk4, dated 1972, in mint condition, I doubt it has ever been used!  Complete with leather case, leads, probes and destructions!

    Second pic is the Mk5, dated 1973, same condition and accessories.

    I've been after both versions, in this condition, for years!  They weren't cheap, but then again not expensive considering what they cost new!
    The Mk5 was £500 in it's day!  So my Avo collection nears completion, I need a model 9, which is extremely rare, a Mk6 and a Mk7, those not so rare but difficult to find as new. The 7 was the last Model 8 made when production ceased in 2011, list price then was just shy of £800! According to Megger, the company that produced Avo meters then, production only stopped because certain parts could no longer be produced, demand was actually still there!! They didn't have the extra high voltage range though, evident by the lack of extra terminals at the top of the front panel. The Mk5 could read upto 3KV!! One of my favourite things about these meters is the test leads, thick, flexible, heavy duty, and very high quality!  Even though they have never been silicone they have always been so flexible, even in cold conditions!

    A pair of new 8.75" rack handles for my HP4145A. Ordered all the way from the USA. Wasn't cheap but worth it imo.

    My snipe from last Saturday: a HP7225B flatbed plotter. Tested today and promptly blew the mains input filter after a couple of minutes of playing around. It moves, is in rough cosmetic condition and the GPIB isn't tested yet. Some Refurb required all in all.

    Also it really is the "budget" plotter of the lineup. The Plastic case is largely non structural and not the most durable thing as mine is cracked on the top half in one corner. However an 9872C or similar is even more rare so I'm glad I got this one for relatively cheap.

    Can't wait to have it automatically plot graphs from the 4145A once I got some pens!

    There are a few of this type of thing on ebay these days, I got a 3D printed version with a nice authentic looking Eveready label!  It has a screw attached end so that a new stack of cells can be inserted.  Once upon a time Avo supplied a voltage converter powered by an internal 1.5 volt battery, it was the same size as the original 15 volt battery.

    Yeah, Avo made tens of thousands of various models, most of which had hard lives in industry and servicing, so although fully working many were very beaten up!  I have quite a few spares or repairs units to salvage spare parts, some are blown to hell on the inside!

    A fun fact of Avo's, they all had a smudge of grease on the inside of the bottom case.  This causes head scratching with those new to the cult!
    It's there to catch any dust, debris or small parts that may have found it's way inside!  So when the meters next went for servicing and cal, the tech could see any tell tale evidence.

    I've always liked PTFE, although it is the fashion these days to go :scared: :scared: :scared: about it because it apparently releases some nasty stuff when burnt---I certainly remember some stinking fumes that made my throat catch, but it was just momentary, & we never thought it a big deal.

    At work, we had quite reasonable sized sheets of PTFE, but "scrap bits" is all I had in my private stuff, down to zilch today.

The 7 was the last Model 8 made when production ceased in 2011, list price then was just shy of £800! According to Megger, the company that produced Avo meters then, production only stopped because certain parts could no longer be produced, demand was actually still there!! They didn't have the extra high voltage range though, evident by the lack of extra terminals at the top of the front panel. The Mk5 could read upto 3KV!! One of my favourite things about these meters is the test leads, thick, flexible, heavy duty, and very high quality!  Even though they have never been silicone they have always been so flexible, even in cold conditions!
    The Mk3 that I have a few of was never quite enough until I got a tidy Mk5 especially for its 3kV range.
    My solution to the 15V battery issue was a stack of LR44 with a little copper tube each end to pack out to the 15V battery length, all excepting the very ends covered in heatshrink which allowed for a neat fit into the OEM 15V battery holder.  :phew:

    The lead set for yours looks in spectacular condition along with those darn hard to find hook grabbers of which I also have a pair.
    Nice find, treasure them.  :-+

    Being a bit of a vintage test gear nerd, I scored these beauties which arrived today!!

    For new players and those that are not familiar with UK test gear brands, these are the legendary Avo 8, possibly the best analogue multimeter ever made.

    First pic is the Mk4, dated 1972, in mint condition, I doubt it has ever been used!  Complete with leather case, leads, probes and destructions!

    Second pic is the Mk5, dated 1973, same condition and accessories.

    I've been after both versions, in this condition, for years!  They weren't cheap, but then again not expensive considering what they cost new!
    The Mk5 was £500 in it's day!  So my Avo collection nears completion, I need a model 9, which is extremely rare, a Mk6 and a Mk7, those not so rare but difficult to find as new.

    They will be cherished, which sadly means they won't see alot of use, the penalty for having survived in such superb condition.  I do have some users though, which I like to use on vintage valve equipment, seems so appropriate! And of course indicated voltages on old service sheets were measured on Avo's, or 20K ohms/volt meters, so it's easier to compare readings.

    I went through a phase some years back, of buying up every set of Avo leads, probes, clips etc in excellent to new condition I saw on ebay, so I now have a good stock!  This was before prices began to escalate.  I also bought loads of the shunts, voltage transformers etc.

    Although my collection is nothing compared to a fellow collector I know, about 40 miles north of me, he has just about every Avo meter and accessory ever made, and, a huge stockpile of parts!  A whole room in his house is dedicated to their storage and display, shelves all around the room, about 5 or 6 high, it is truly incredible! And, he repairs and restores them! 
    Sadly, Megger are just not interested in the meter that established their name and reputation, so have no company collections or archive document library.  So it's down to those like myself and above mentioned friend to preserve their history.

    I picked one of these up at an MOD clearance sale years ago.  The sale was mainly for workshop equipment, like machine tools etc, so no one knew what it was, I got it for peanuts!  Superbly made instrument for modern stuff.

    Well... they're not really useless, they're weak. OK for plastic, printed circuit boards, brass and aluminium (thin!), etc. Just forget about steel.

    The shear blades tend to separate because the frame and the pivot stud are not strong enough. Also the blades themselves are of a very doubious quality. Wobbly and weak two part lever (thin wall tubes) with a loose fit. Also the bolts linking the lever mechanism are threaded along their length, that is, the threads are pressing against the bearing surface; a very poor and loose design. Had to provide some washers to mitigate some of the looseness without much success.

    Again: cheap shears with cheap results. You get what you pay for. Only useable for very light jobs.

    I seem to be on a bit of a mission with multimeters at the moment, but when a bargain like this appears it's difficult to pass up!

    It's just a fairly basic DMM, 4000 count,  0.5% to 1% accuracy on DC volts, depending on range, other ranges between 1 to 3%, the 3% is on the AC 10amp range.
    The best thing is build quality, very solid and robust and being Megger, components will be high quality, so long term reliability will be excellent.
    £50 on ebay!  It's a discontinued model, this one is NOS dated 2006.  The original price was higher but I added to my watch list and a shorlty afterwards the seller offered it for £50, which didn't take me long to accept!  He has another 3 if anyone is interested but I can't be sure that he would offer that price again. Also, it is listed as a 300, but I noticed the box showed it to be a 310.

    And another multimeter, quite an unusual one this time!  Got this for a bargain price on ebay, it's a current model and the list price is over £500 in the UK, I paid considerably less than that!! It's used but in excellent condition appearance wise, it was described as fully working but unfortunately is not! Everything works except the resistance ranges, select any of those and the pointer just goes hard full scale. Contacted the seller to make him aware of this and to his credit he offered a full refund and pre paid return. Initially I was going to accept that and return it but on second thoughts decided to keep it and try and sort the issue.  Slight problem, I can't find a service manual, the manufacturer says in the event of a problem to send it to a service agent. So, if anyone does have a copy of the manual, or knows how I can get one, please let me know.

    I never really understood why they were so expensive, I can't see the point in having a manual ranging-only meter these days, I must be lazy...
    Your meter reminds me of the Metrix MX570, old and scarce but at least you have autorange. There's one on eBay now but it isn't going cheap.
    Set aside their Scopix DSO's and some good clamp meters I'm not that impressed with Chauvin Arnoux's recent products.

    You could try getting in touch with Manumesure in France who are the biggest (C.A. / Metrix) repair centre, good luck with obtaining the schematic tough, I'm under the impression there aren't many schematics to be found because they don't want them released.

    Brought a second baby Compressor for not much for the Electronics clean part of the workshop :-+ With discounts and vouchers it was $150 AUD (about 100 USD) delivered with Tax. eBay auction: #195246777489 Still a few left if any Aussies are in the market for one.

    My dirty shop that has the 100L big compressor looked like costing me most of the cost of this one to run the plumbing properly and this baby is more than up to blowing some dust bunnies out of electronics and running my Laser Cutters and an Airbrush or blowing up a bike tire. Running out a 20m hose through two doors was getting really really old when I needed some air.

    Bonus is it is also way quieter than my big 'silent' one so under the bench it is easy to talk over when running. Not expecting it to run a Spray Gun or Air Tools so actual volume wasn't important.

    They were common "back in the day"--both NEC & LGT used them, the latter to excess, in my opinion.

    Standard locking switch, has been a staple of avionics for decades, where you need a switch that is easy to change state, but accidental operation is hard, but you can still do it while feeling by touch and wearing gloves.

    As far as I know, Pomona are the manufacturer for most Fluke probes. So if you have any newer original Fluke probes they should be identical.

    Yes, the TwistGuard one. Equivalent to the top picture but the grey in yellow - TL175.

    Also the TL221, TL222, TL224, TL71(second picture but Fluke branded) and TL76 have their leads in Silicone.

    Doesn't seem electronics related but I was getting burnt out from electronics work and hadn't had a bike for 10 years.  This is helping me appreciate work again.  Also bought a miter saw as I plan to re-organize my garage to make room for the bike.  When I do that, I'll build cabinets around the saw and wanted to build around a good saw instead of the old cheap one that I wanted to replace some day.  It comes with a "bright LED light for precision cut alignment".

    Makes it great for making your own audio interfaces with your own front-ends and ADCs/DACs.

    PriPrinter (https://www.priprinter.com/)

    As a long-time (very long) user of Fineprint (https://fineprint.com/fp/), PriPrinter has a few better options and a bit easier to work with.

    For those not in the know, these are virtual printers (for Windows) which you would set as the default printer. They then intercept any printouts and let you view what might have been 200 blank pages before you commit them to actual paper. You can force duplex, multiple pages per paper page, vice versa (print posters using A4 sheets) save to PDF, edit, redact, letterheads, etc. Saves a ton of paper and ink.

    Specially now when the dirt is up in the hills and still covered in snow, it's nice to have pavement as an option.

    Sticker came with the bike: 'Warning, this vehical makes frequent stops'.

    Mainly have classic bikes, including a Velocette and a Vincent Rapide, currently my most modern bike is a 2005 MV Agusta Brutale, my second ever only in line 4!!
    Biking is therapy to mitigate against modern life and one of life's best forms of recreation.

    Those WRs rip.  Tried my friends WR 450 years ago and my DRZ 400 felt so heavy and slow after that.  Been wanting a faster, lighter bike ever since, very happy with my chocie of the FE 501.

    When my son turned pro off-road racer he was sponsored by a dealer that supplied him with Italian Husqvarnas,  This WR150 was from his 2010 season.

    I had a 2006 WR250 too.  I think that era of the Husqvarnas were the best looking dirt best ever, until KTM bought them and just put the name on white/grey KTMs with Husaberg kinda styling.  Methinks something was lost.

    Nice bike!  Some of the electric offroad bikes look a bit terrifying.  All that Insta-torque.   Personally I downgraded from a CBF1000 to an NC750X.  Still lovely the big twin "BLAP" on the downshift.  Just can't stop doing it :)

    Yesterday I bought...

    https://www.sunstore.co.uk/product/epever-up1500-m3222-24v-1200w-inverter-charger/ (https://www.sunstore.co.uk/product/epever-up1500-m3222-24v-1200w-inverter-charger/)

    I was surprised because the last time I went looking, for off grid hybrid inverters that would NOT export, they were £3k+.

    Then I spotted a couple of these Inverter + Charger hybrids from Victron around the £1100 mark.  Decided to shop around and as I have had several EPEver devices and found they work fine, I decided to take the plunge with PayPal 3 Month 0%.

    Figured paying the extra to have it shipping from a UK supplier was prudent.  Could have saved £100 on AliExpress and waited a few months for it.  However if it shits the bed I can ship it back for £30.

    It's basically an MPPT charger, a mains battery charger and a transfer switch in the same box.  Can be configured in various ways including as I intend to, by connecting the mains feed onto for use as "Backup generator".  Tell it the solar and batteries are the primary power source and the "mains" is a backup generator (of sorts).

    Although I have the Fluke TLK-225 kit, I don't have it currently with me (still back at my home country, together with my 289) so in a job I have to do this week I need this specific ones. True to be told if I can get the other 2 missing for the same price I got this 2 I will have the full kit (minus the transport pouch) for half less I paid for it back in 2016.

    And that's including one of my last posts where I got the TL224 and the TP220.

    Ox64 (https://wiki.pine64.org/wiki/Ox64) SoC in MCU size; the 2MByte NOR-flash one without microSD slot, based on Bouffalo Labs BL808.
    Was also the easiest order I've ever made from outside the EU: within a couple of days of placing the order, I got the order confirmation, and a few hours later from my local Post a notification that I can do the customs declaration.  I did that, saving a couple of euros, online; and then it was just a wait for the package to arrive, tracking as it progressed through the systems.  :-+

    Much more interesting is the bottle of homemade unsweetened steam-extracted blackcurrant (ribes negrum titania) juice from my mom that unexpectedly appeared in my fridge.  Having had a lingering cold for a couple of weeks now, I had already drank the bottle I had (diluted with hot water; yummy), so this evening I was very pleasantly surprised to find that the house elves/aliens/friendly spirits/spatial anomalies have transported another bottle from 1Mm away to my fridge. ^-^

    Also 2 cat6 Ethernet cables and a few cans of Happy Belly Chicken Noodle Soup. This is a good item useful for hitting the $25 minimum for free shipping. You can eat it and it's a little cheaper than the Kroger (local store) equivalent.

    Decided a touch screen might be useful on the CNC toys and went looking for a 21" 1080P Touchscreen. I failed badly and brought a 27" QHD one instead :-DD

    The ACER is I understand becoming an old model but the price was really good with some evilbay discounts applied. eBay auction: #265597687621 . The Touch part works well so far based on an hour or so of playing and it will be interesting to see how it stands up to some dust and dirt over time. I have tried it through a layer of thick plastic bag (worked fine) so an extra layer of plastic might be in order.

    Finally got around to building the 5600G APU system to pair with it to go into the enclosure. The RX560 was just for a test and see how it ran dual monitors but it will be coming back off the MB. Yes I really to need a bigger workbench or my Coffee Roaster needs a new home .......

    I read somewhere that this type of computer was probably based on a reference design by Intel. Both Dell and Lenovo had similar versions. I've never been a big fan of Dell, but I did look at the Lenovo versions. I finally settled on HP mostly due to appearance and what I could find for sale. I didn't even plan on buying one of these. I was actually looking for something I could use as a pfSense machine. Still am I guess.

    This has been bugging my YouTube feed for the last few days (video only came out 4 days ago). I did look at one of these for my CNC box before deciding to go for the 5600G and board. Plenty of them in Oz and they seem to be plenty available from workstations.

    Why else do you think I went for the 5600G. 500+ FPS on 640x480 I reckon while this mini will likely peak at 1-200.  :-DD

    I have actually done some testing with the Ryzen at 1080P you seriously could game with it providing you keep the settings wound back, hitting 60+ FPS wasn't hard to do on slightly older titles I had on a SATA drive I dropped in for a play.

    If those HP G2 mini units give you trouble by shutting off randomly, you can try upgrading to the 95W adaptor (still really cheap used). That's how I salvaged a couple from the dumpster, they were "faulty".

    They idle at like the 8-10W mark so I used to use it for 95% of my computing before I upgraded to a M1 Mac mini. My old gaming PC (or even a modern gaming PC) still idles at something stupid like 60W or so.

    I was just about to post that I bought a new Mini PC, but I see others beat me to it!

    Grabbed myself an HP Elitedesk 800 G2....  not what was delivered.  An HP Prodesk 600 G3 arrived.  Almost identical spec, looks nicer, slightly more recent, better memory.  Bonus!

    £115.

    Idle power:  6.5W
    Installing Windows 13.5W.

    Supports 4K 60FPS and ultrawide IF and only IF you are using DP or a proper active DP adapter.  It wont do it through a passive adapter, as it drops to HDMI specs.  I believe the port can detect the adapter, a DP++ port.

    Not electronics -- actually it is.  I have been waiting for the next Nikon sale to get its Nikkor Z MC 105mm (macro with stabilization and autofocus).  I hated trying to photograph my little projects with an older (Y2K) Canon point and shoot SX100.  That came to its righteous end when it fell from my tripod onto a hardwood floor late last year.  In the70's, I had acquired a Nikon F in Hong Kong and eventually got the 55mm macro for it.  Once installed, I almost never removed that lens. Of course, using 35mm film is just not practical today.

    The current 55mm macro for Nikon Z doesn't have great reviews, so i popped for the 105mm   Sure, a little bit of overkill.  Attached is my first image taken with it.  Hardly any attempt was made to steady my hands, focus, or not jerk when pressing the release.  I am impressed.  VR and autofocus do work.    The center footprint is for a TQFP44 chip. BTW: For a lot less you can get a good D70 and 55mm AI lens.  Not much advantage paying for useless pixels in the D80 or D90, but the D80's are still pretty cheap.

    PS: That  is a Win7 snippet.  The actual image is quite a bit sharper.
    Edit: I decided to upload a little better cropped version.

    Congrats! I find the increased working distance of the longer focal length macro lenses very helpful for high reproduction ratio shots. With the 55mm at 1:1 I find it very hard to light the subject without casting a shadow unless using a ring light. For lower magnification shots of say an entire PCB the shorter focal length is probably more convenient.

    Note that the D70/D80/D90 won't have any exposure metering with lenses without chip (autofocus or AI-P). For that you have to step up to the D200/D300/D7000 etc.

    Thanks for the added advice, alm.  I was talking about going really cheap.  I got a D70 in great condition for $25 incl shipping, and the 55mm macro can be had for $25 to $30.  I paid about $50 for mine AI with caps and like new.  They are for a semi-permanent copy stand with known lighting.  Post-exposure adjustment gives one a large range of exposures. 

    I did not spend that much just to post a few pictures here.  I live in the middle of a woods with a pond.  Wildlife, particularly the variety of birds I see is great compared to my big city life up until now. I like to document them and get help identifying.  Raptors, including golden and bald eagle, visit not infrequently.  Over the weekend, I saw the first Northern Flicker of the year.  What I posted here was just a trial shot to see how well those modern enhancements work.  I was impressed, and frankly, a little excited at the moment.

    I found a set of slitting saws in the local bargain shop for $7, I relayed an image to a mate and he said they are $5 in a nearby store so I told him grab another set. I have a collection of larger slitting saws and arbors for the mill but not much at hand for the dremels and die grinders so these will come in handy.

    I had my first AAA LSD NiMH battery go high impedance serving remote control duty, a 2009 era Maha Imedion, it fails the C9000 impedance check upon charging.

    The IKEA LADDA have gone down in price on the Australian store so I bought a bunch (they jacked the price a year ag). They have much cheaper shipping for small items now only $5, it would cost me more in petrol to go there and back. Use the $15 off $50 coupon if you haven't yet, you'll find it on ozbargain.

    It's a shame they discontinued the 900mAh AAA cells, you can only get the 750mAh variants now. Oh well at 2 dollarydoos per cell I'm not complaining. Fingers crossed they're still the made in Japan variant.

    14.45 is charge target is it not ?

    Yes and no.

    14.45V is the required PSU output to actually produce 14.40V across the battery.  It doesn't matter with 2 amps.  Does other times. 

    Raising charger voltage to account for voltage drop and trusting the battery is an advanced technique not suitable for being left unattended.

    The BM235 says the Aneng voltage is reporting 30mV high.  It adds margin, so I'm fine for this test and these conditions.

    It's on 13.63V PSU to produce 13.60V (Aneng) and 13.57V BM235.

    The current I was looking for was about 0.01C + 1.4A load.  It settled higher about 200mA higher, so I switched it to float.  Current didn't change much at all.  Continues at 2.3A - 1.4A load.  I'd say it's charged.

    Next phase is finding where it bottoms out on quiescent, load following.

    Why?  Why not?  Fun?  Toys?

    I actually bought 2.13" 3-color ePapers a few months ago, and my original plan was to use them for my DIY resistor box project (for calibrating my milliohmmeter), but before I started I read the datasheet and realized their refresh time was too long, so this time I bought the two-color ones and hoped they were fast enough. As for the 0.97" ones I showed earlier, I think they're great for displaying my 404 logo (meaning they don't really serve any purpose).

    A small 2 colour ePaper display. Not because I have a project for it, just to play around with until I think of a project it would be useful for.
    The display update time is ridiculously slow, so for many purposes it would be quite useless.

    My ePaper was delivered yesterday and is much smaller than yours!  ^-^

    Ok, so we both came to the same conclusion. I believe the display I have (2.66in) states 15 seconds to refresh the entire screen. So I could use it on my "How much has the grass in my garden grown" sensor. Anything else is too fast for the display.

    Provided its not a HID device. :(

    A bit later:
    Its not a HID device.  :-+ But it uses a PL2303 chip some
    versions of which do not work with Windows 10 or 11. :--

    my problem is ... I have no analogical voltmeter and I need one to make a "capacitor tester".

    Kind of ESRmeter but with a fuzzyfied scale measuring voltage in a testing circuit that probes for the active power and using a needle rather than a digital display for  readings:

              ESR(CAP) ----> { garbage ..... walking dead .... decent .... good ... excellent }

    5 positions of the needle, from left to right

    should I buy a cheap one?  :o :o :o

    I got to a radio flea market this yesterday. Bought a bunch of old components, plus a board with some metal can transistors. I was hoping to find a jfet or something, but it seems those are just some regular bjts.

    I also saw components that I've never seen before: half-bridge rectifiers (or dual diodes in series). There are like a normal diode bridge, but half of it, and only three pins. I saw part numbers such as OF475 (from Phillips) and V15C250. They are small, comparable to IR 10DC-1R (which is easy to find on the Internet). Can't find anything on the Internet about them. I don't think they have any special properties, so no big deal, but curious why I can't find any info about them. Sadly, I didn't take a picture.

    The 2 1/2 4TB has always been just a bulk dumping ground either for whole PC's worth of docs or Post the NAS going online a remote backup of it as a disaster recovery option. My main PC also syncs and holds everything on the NAS except for Videos and Music files as they don't change much and losing them isn't important. It gets plugged into the back of the NAS and I go to sleep so speed isn't a factor.

    The new 'toy' is more going to get used for bulk dumping of anything I might need from PC to PC and it will also hold an extra redundant copy of my photos and really critical docs.

    The Seagate 3 1/2 was USB2.0 from memory so it is a total slug in a modern environment but for video playback it is fine which is it's likely use from her on.

    I would be more concerned that the M.2 SSD has a fanless case. I ran a couple fanless in the PC and they didn't do well, so now I always shove a fan on those. And my spares in external cases get very hot with long operations, so I always use fanned externals now too, except if I'm just pulling a couple of files off, say.

    I saw the same thing with external HDDs in long operations, but I now use only enclosures made of metal/aluminium that do an excellent job at dissipating the heat to the case itself.

    Cheap Solder Sucker Desoldering Iron

    this is the most basic level of a desoldering iron if you seek to live dangerously.
    as seen here. I go this one out of mostly curiosity.
    the 220V AC Desoldering Iron needs a 3 wire replacement cord and 3 pin plug. before plugging in to my
    240V to 220V autotransformer.
    the 4 screws are under the plunger knob and the black plastic shell has 3 grooves set into the plastic.
    but only 2 are used to cheap out on the not suitable for single insulated 2 wire power cord.

    I use EU 3 pin plugs for my 220V tools to avoid miss-pluging things into 240V AU wall outlets.
    also did not show any power cord modifications here.

    Europe uses 230 V, as long as your local mains doesn't go above 244 V it's in the tolerance window of EU mains voltage so you don't need a transformer.

    I remember back when MV.2 drives appeared on motherboards.  They were typically placed right under/in between the GPU and the CPU in the hottest part of the board.  People, of course, started reading temps of 60*C+ and many forum threads errupted.

    The manufacturers said, "And?"  "Whats the problem?  It's meant to run at 60*C".

    But of course out came all the cooling products for MV.2 and SSDs because "60*C" can't be good for it, right?

    I seen tests where LMG (LTT) tested a water cooling block for a gen 4 PCIe MV.2 drive and .... it performed worse when cooled by about 25%!

    Similarly the chipset (SoC) in my motherboard routinely idles at 60*C and games at 65*C-70*C.  I have seen it hit 80*C!  Yet Asus shrug and say, "It's fine, meant to do that".  Yet.... coolers are now out there on the market to cool the SoC.

    Yeah, I know they are meant to be OK running hot but I have captured one slowing down when it got warm. Also got one that slows to a crawl (literally, kbps) when accessing parts with data. My view is that, like with salad in a fridge, cooling can't hurt but could help, so I play safe.

    Not all NVMeE drives are created equal either. Apart from the recent one which is a WD SN770 Black all the rest are Samsung EVO 970+'s (think I have 5 in use) my main Boot drive ticks along at around 50C most of the time so  :-// Even the shack box when ambient goes over 40C as the case has great airflow I have never noticed an issue.

    As to externals HDD (spinny ones) getting hot I really don't see how around 2W even in plastic is going to be an issue. Sit it on top of your PC case maybe but again never seen it be an issue. The 2 1/2 just spent about 20 hours taking a backup from the NAS overnight and I couldn't pick it as being even warm.

    I might drop CrystalDiskmark and info on all three of my externals and start a thread just for interest.

    I got a new watch.  ;D  (We really need an "I'm Excited" emoji thing).

    I bought from an Ebay seller  (https://www.ebay.com.au/itm/394233378001?)a Skmei 1894 Digital Watch which has a huge uncluttered display and will be handy for cycling where you only get a second or two to glance at your watch. The all important feature list: Count Down Timer, Stop Watch, Day, Date, Dual Time, Alarm, Chime, Huge Wrist Strap and a Big CR-2025 Battery, I'm a big battery fan.   :D

    One very nice feature is it shows indication on the main display whenever a back ground function is active such as count down timer, stop watch or alarm. It also has an Electro-Luminescent backlight the same as my Skmei 1278 and 1381, much better than the illumination on my Casio watches.   ::)

    I would avoid multibay enclosures.  I have a 5 bay.  I replaced the 120mm fan in it's base with a Noctua silent fan.  I am now going to buy single bays for all but the two raid backup drives.  Why?  The controllers in those multi-bay units try and do their own power saving by spinning down all the drives.  Thats fine.  What isn't fine is, should the OS access any single one of them, the whole lot get spun up in sequence taking about 20 seconds.  The sub millisecond disk access happens on only one drive and 5 minutes later it spins them all down again, until something pings a file an hour later.

    On temps, when the drives are all on and running the evening RSync to raid I've seen 48*C and a "life span" flag/warning of 47*C IIRC.  It's been a while and to be honest I disabled the SMART monitoring as it was IT pinging the damn drives every 10 minutes.

    Soon I should be able to afford solid state storage for all "online" drives and the spinning metal can demote to "offline" "ondemand" drives.

    Are we talking the same thing? My comment, on temperatures with externals, was about M.2 SSDs but yours seem to be thinking rotating disks.

    Having said that, I wonder if such external multi-drive cases would be available for the SSDs (other than the two-drive ones). It would be very compact in comparison.

    Got one of these.  And here ends my short phase of buying cheap multi-meters.

    https://www.owontechnology.eu/product/1362517/owon-b41t-4-1-2-digit-digital-multimeter-with-bluetooth (https://www.owontechnology.eu/product/1362517/owon-b41t-4-1-2-digit-digital-multimeter-with-bluetooth)

    I like it, nice size, feels nice, screen look gorgeous.  I haven't really tested it out that much.  I tested it's resistence at the lower end with a 0.1Ohm resistor and it wasn't exactly accurate registering between 120mOhm and 200mOhm.  The ESR meter says the resistor is 96.4 mOhm.

    I like the 5th digit, even if it's not totally accurate enough, but for working with slowly moving voltages like battery charging, having the extra digit a bit like the seconds hand on a clock is nice just to look at.

    You can disable the auto power off, but annoyingly, like so many DMMs it does not disable the back light timeout.  I think out of 5 meters I have bought only one of them has that feature, the Aneng 9000 the backlight stays on if you disable auto power off.

    Another negative on "useability".  The backlight button doubles up with "HOLD".  If you press and hold the button to turn the backlight on, it also enables HOLD, which is easy to miss.  Has to be disabled with a short press after the long for backlight.

    Just received the Aneng MH-13 (https://www.aliexpress.com/item/1005005001503286.html) megohmmeter. Very decent device for reasonable money, listed at $57 at the time of purchase, but with all the discounts active at the time I paid only $55 total for the MH-13 and the Aneng A3008 (https://www.aliexpress.com/item/1005002134436650.html) pen-style multimeter that I decided to buy for the sole purpose of satisfying the irrational desire of getting yet another multimeter.

    What an awesome toy a megohmmeter is!
    This model can test at up to 2.5 kV and measure resistances of up to 200 GOhm. Now I can easily blow up trashy multimeters and create beautiful blue sparks across narrow gaps between two conductors!

    For the slightly more practical application, I can now do proper testing of e.g. flux conductivity and dielectric strength of PCBs. For example, I found out that a typical Chinese Green Double-Sided 2.54mm Protoboard™, when tested unused out of the box, withstands 1kV, starts to conduct an occasional spark at 2 kV and allows a sustained spark discharge at 2.5 kV between two adjacent pads.

    One downside is that it is powered from eight AA batteries. I would much prefer a built-in Lithium battery. But there is sufficient room in the battery compartment to fit 3 x 14500 or flat Li-Ion cells, should I really want to do that. Will see how quickly it drains the AAs first.

    Pretty sure I've measured seriously high temperatures in external cases when doing backups, hence my preference for one with a fan. Maybe I'll join your thread and run off some new measurements :)

    I would avoid multibay enclosures.  I have a 5 bay.  I replaced the 120mm fan in it's base with a Noctua silent fan.  I am now going to buy single bays for all but the two raid backup drives.  Why?  The controllers in those multi-bay units try and do their own power saving by spinning down all the drives.

    Are we talking the same thing? My comment, on temperatures with externals, was about M.2 SSDs but yours seem to be thinking rotating disks.

    Having said that, I wonder if such external multi-drive cases would be available for the SSDs (other than the two-drive ones). It would be very compact in comparison.

    A NOS Campy Zonda wheels 8speed (90s old new stock) set ~ 450 euro
    A NOS Campy Shamal wheels 8speed (90s old new stock) set ~ 1000 euro

    my Zonda wheels are secondhand, paid 120 UKP, not too bad  :o :o :o

    I don't like carbon forks, only steel forks on a 90s titanium frame, but I needed something more comfortable than my old Mavic X wheels (very cheap, paid ~60 UKP secondhand) for longer bike rides.

    Now I'm thinking of disassembling the Campagnolo Zonda wheel and mounting the Zonda rims on Mavic hubs.
    Kind of hybrid Campy Zonda-Mavic wheels.

    Closer to the day, I will have to check if SWMBO is all good with it.
    She is a bit immobile, so won't be able to come, & I am her "primary caregiver".

    Don't get me wrong, she "has all her marbles" & physically can do quite a lot, but she needs assistance with some things.
    She will almost certainly say "go for it", but I don't like to leave her in the lurch if she needs assistance.
    What with her condition, then the Covid episode, we have both become a bit reclusive.

    Crazy purchase, not because steel is better than aluminum, but rather because of the late 80s style.

    But, wait, Campagnolo Zonda 1995 wheels paired with Campagnolo Victory 1985 headset!? 10 years of difference and completely different styles, doesn't it look ... a bit steampunk-ish?

    Yup, it does!  8)

    I highly recommend to check/replace the electrolytic capacitors (see https://www.eevblog.com/forum/testgear/restoration-glory-of-keithley-2001-dmm (https://www.eevblog.com/forum/testgear/restoration-glory-of-keithley-2001-dmm) if you are not convinced) and when you do that, you will get an idea of the manufacturing year by the date codes of the components.

    From my point of view the 2001 is very prone to leaking. In my impression it is a rather common defect with older devices of that type, because they placed the caps in a rather warm area of the device. Here is, how my caps looked like and they also took a power resistor and a custom transfomer ... with them.

    2009 by the look of the IC date codes, so that might be newer than the worst of the capacitor problems.

    I am back to 90s light steel, Columbus TX tubing, used for the Coppi Mirage bicycle. A young dude made an auction to sell his father's bicycle.

    All his photos showed a rather dirty mess of dust and oil with a horribly scratched saddle, but a wonderful long-cage Campagnolo Mirage derailleur and a Daytona derailleur mounted next to a triplex chainring crankset catch my attention  :o :o :o

    So I immediately reached out to meet him in a car parking zone near a train station, with the precise idea of buying only a single ticket and putting a portable mini inner tubes pump able to pump up to 8bar, two inner tubes, grease, pedals, Allen keys, good for the derailleurs and rim brakes, but also for pedals, and other tools into my backpack.

    No return ticket! Easy plan, meet the guy, pay for the bicycle, immediately mount a side stand to be able to work on the bike and fix primary issues: as changing the saddle,  changing inner tubes, cleaning gears, adding grease to the chain, regulating wheels, regulating gear registers, etc, and turn back home with it, fixing secondary issues along the way home.

    (http://[attachimg=1])

    And so I did! A lot of things could have gone wrong on a bike that hasn't been ridden for 10 years.

    210 km, 7 stops to regulate secondary issues, four bottles of water consumed along the trip, and 5 kg of metal (tools) in the bag on my shoulder.

    It worked  8) 8) 8)

    (except ... 5 km from the garage at home ... it started raining cats and dogs
    d'oh)

    Soldering pincers with interchangeable quartz points. Will be interesting to see the benefits. Did anyone reading this work with these in the past? They were made for dental applications, but sometimes tools from other disciplines can be quite helpful. I think a melting temperature >1700°C is beneficial, when you are soldering at high temperatures with flames, what we typically avoid when soldering components onto PCBs.  :)

    My video endoscope had a broken display, when I took it out the box which I stored in the cupboard after using it the time before. Maybe the camera pressed onto the foil in front of the display, when it was in its box. However, I decided to buy a replacement 5.5mm endoscope and the new one has a second camera looking to the side and a better image quality.

    Manufacturer calls it "Dual Camera" and I think that is true. I can see two lenses and I guess the sensors are cheap enough to not share them. The endoscope units without display are rather cheap (about 10€). The "dual camera screen endoscope" is approx. 50€.

    I thought glass is not ESD safe lol, they charge up glass rods IIRC. Rub a textile furthing on a glass rod or a plastic rod and it holds a charge.

    Kind of wonder about ceramic tweezers too, I bet they should be made out of nitride or something conductive

    qty=1, IKEA metal shelving, to be used to accommodate the two RAID units

    despite they are Hardware RAID{0,1,5}, you can switch to "bow-mode", this way on the interface you just see four disks, so you can use software kernel RAID functions.

    A whole lotta screws for my HP4145A and 7225B Plotter. The former is missing some and the latter needs new ones as someone once upon a time managed to bend nearly all 4-40 UNC ones on it.

    SUB-D 25pin Connectors and symetrical cable. To convert the Centronics 24pin interconnect cable between the 4145A and its Test Fixture to SUB-D. Trying to convert a HP-IB cable to straight Centronics 24pin proved to be just a headache.

    TWO Network Analyzers. Wandel&Goltermann SNA-62. One functioning fine and the other with seemingly several problems. Local Oscillator doesn't seem to swing and some brain rot. Might be BootRom, RAM or some other digital problem. The functioning one will repair the other one after using it as an Troubleshooting aide.
    A project for the Winter though. After cleaning and inspecting the functioning one.
    Need to get a Operator Manual for it too.

    HP3577A Operators Manual. It was cheap and available. A picture book for grown ups essentially. And a sad reminder how great Manuals once were in decades past.

    Price for the 100khz version is under 300€ if you don´t buy it from ebay..
    Basic accuracy 0.1%, 16 testfrequencies up to 100khz (ET4410), list function, outputlevel up to 2V, even DC-Bias up to 1.5V...
    Works with SCPI commands..
    This is the second one for me(first sold last year to buy an defective hioki 5Mhz lcr), buy it again because I want to finish "reverse engineering" and to have a second LCR for comparison measures.
    Tested the first at work against yearly calibratred LCRs from keysight (U1733C) and sourcetronic ST2830 (Tonghui TH2830).
    Up to 1khz all are similar from the results, up 10khz it´s still in it´s specs.
    To keep it short here I would say, if you want more than a DE5000 offers and couldn´t spend the money a TH2830 costs, this could be your choice.

    That's also the reason why I picked the 4410. I assume the difference might only be the firmware. In that case, I hope some day there will be a way to upgrade to get more variable in the frequencies.

    to stack or not to stack

    Stacking (actually, having instruments above the bench space) makes it difficult to look at what you're doing as well as reading the instrument display. OK if you, say, connect solidly then look, but an issue if you're hand-holding a probe.

    OTOH, not stacking (having the instruments as in your first photo) makes it easier to see both the work and display at the same time, reducing the risk of slipping probe or probing the wrong thing, etc. But you lose work space and have leads all over the place, and you need to keep swapping out the instrument you used before with the one you want to use now.

    One solution is to have a display at work level with the instrument itself stacked on a shelf. The display might be from the instruments HDMI/VGA port or a PC connected connected in various ways. For instance, a Keysight DSOX can drive an external display, of you can have a pretty much real-time display via a browser. Many Chinese instruments have Android apps.

    So you watch an item on evilbay partly out of interest to see how the pricing is currently and the seller a few hours later sends you an offer for about 25% off and you look at how much food in in the cupboard for the next few weeks.....  :-DD

    I am weak (stop laughing @Brumby) so seems I will be adding an Agilent E3620A to the front bench because you know Power Supplies you never have enough there is also a gaping hole where the 735A Transfer Standard has been living for the last few years so in the interests of open space collecting 'stuff'  it had to be done :-DD

    This is a clever way that eBay found to foster sales. I fall prey to some of these from time to time, to the point I now only add things to my watchlist in times of excess hobby money... 😁

    The big question: E24, E48 or E96? I went for E48 but still needed a special area for resistors that I needed that aren't in the E48 series, despite doing mainly digital circuitry.

    I changed to the Ender Touchscreen, but it was missing basic functions that I use, such as filament change (for multiple colour prints) and even manual filament change wasn't properly implemented. I changed back to the old screen with the knob and spun my own version of Marlin and could add what I wanted. The touchscreen firmware is closed source, so adding features yourself can't be done.

    My HP linear/triple power supplies 6205C, 6236B, 6237B are my benchtop favorites.

    Recently found  pair of 6205C in fine condition.....very reasonable cost. One needed a lot of cleaning but ISO alcohol and a bit of time yielded a clan unit.

    All meters, controls and functions were fine after some contact cleaner and exercising controls.

    The regular  version has a 10 turn Helipot voltage control but just a plain HP gray knob.
    A friend in Netherlands scrounged 4 pcs of the rare miniature Beckman 10 turn count dials with special mounting nut and collar.
    Alignment requires a spanner pliers and the exact hex key: Three different dial components  need to be setup.

    Thus I converted the pair of 6205C into the precision dial option.

    Plot is the stability of one PSU under lad with warmup drift.

    These 1980s vintage units built in USA with typical HP gold plated high quality PCB and components. Huge HS on the back.

    Your thoughts?

    HAVE AN ABSOLUTELY FANTASTIC DAY!

    Picked up a basically free Precor C956i commercial treadmill that wasn't running. The original motor drive died and a used replacement is in the hundreds (new is nearly a grand). Even if I changed it I'll be at the mercy of the top controller board in the future so I decided to just plop in a VFD.

    Hats off to Omron Australia they are extremely well priced here (~220USD) and I got the thing 36 hours after I ordered. It's a 3G3MX2-AB0015-V1(Q2), a single phase input 1.5KW VFD.

    First time I've ever installed a VFD but their manual is solid. Now I've never used a commercial treadmill before but uhhh it's slightly terrifying because I can stomp on the belt at speed and it doesn't really slow down much if at all. I need to figure out how to let it "slip" slightly on foot strike(down the PID rabbit hole?).

    When walking/jogging the motor draws 400W-700W so nothing seems stressed. After 75 minutes the heatsink of the VFD is 10C over ambient if that, and the internals a touch higher. The 2HP motor was hard to measure but the highest hotspot I could read was ~48C (18C ambient), on my previous crappy home treadmill it would be 100-120C (and slightly smoking which prompted this upgrade). This was a fun little project.  ^-^

    Supvan E10 thermal printer (https://www.amazon.com/dp/B09JRKY1LD)

    Wasn't too sure about this so got a cheap used one for evaluation, and it's OK. I already have a bunch of different Dymo labellers but they are all tethered in some way to a desktop or laptop. Or USB cable or power supply. The software is a bit sucky too, although it does let you create frames for different styles and orientations of text, at least. Many of my labels do get created at the desk but sometimes I am out in the garage with a bunch of things to label, and going back and forth to create and print each one is just too tedious. Portable labellers abound, but you're limited to what you can get on the lable - text, symbols if you're lucky, and that's about it.

    The Supvan uses bluetooth to a phone, and the thing that caught my eye was the ability to use the label as a drawing surface. Use a finger or stylus as a variable-sized pen and draw whatever the hell you want, then print. That's in addition to the usual text, symbols, smileys, photos, lines, etc.

    Takes continuous 6m tape or pre-cut labels of various sizes and colours, but all with a width of 15mm. Two bad points I've noticed so far:

    1. Replacement tapes may Dymo look cheap, but that's normal for these things (and since they are a small brand there's no third-party clones, or none that I found). Aliexpress halves the price, though.

    2. A single press of the power button reprints the last label. Useful in some circumstances, but stupidly it can't tell the difference between a single press and a power-on press, so every time you turn it on it reprints the last label! Workaround is to open the tape drawer before hitting the power button, then close to use after it's woken up.

    Today I picked up an Agilent/Keysight DSO6104A 1GHz scope today from a local seller that was on eBay for £800. For the uninitiated, the 6000A series was the portable version of the 7000A/B series. This is not to be confused with the current DSOX/MSOX6000 series.

    I'm quite the fan of the venerable Agilient/Keysight MSO7000 scope, mostly because its UI is fast, easy, and intuitive to use. Indeed, my daily driver has been a 1GHz MSO7104B for nearly ten years, with a unit I bought it for about £6,000 from Keysight used.

    In its eBay listing, none of the dozen or so pics showed any of the channels working, and it was "for parts or not working". As it was only 25 miles away I asked if they could show the channels working, or alternatively I could check it out in person.

    The response was "unfortunately we do not have any experience or knowledge in this type of equipment which is why we have done very little in the testing of the item" which we've all heard before, and usually would point to a known duff item.

    But then they said this... "We would be more than happy for you to come over and take a look and test out the machine to see if it's suitable for yourself"

    So I took a punt and popped over there with a probe to test the channels. It turned out to be fully working. I've since updated the firmware and otherwise liberated it with all the decodes and the digital channels etc. I also cleaned up the knobs that were grubby in an ultrasonic cleaner with my usual SWAS detergent, and they came out a treat.

    Bonjour! 

    Was missing a Function gen in Paris.

    At the lab in US unearthed  a vintage1980s HP 3312A in the archives, untouched since 2010.  $25 at ham flea.
    Spec is attached.

    Turned on, Power LED flickers and SMOKE!
    Usual:  self immolated Tant on PSU bus. Beautiful HP FR4G10 gold plated PCB burned.
    Cleaned up, new tant and works 100% even still in cal...13 MHz 20V, AM/FM/Burst/sweep..
    Cap and PCB pix....

    By accident another on epay, but panel blemis and "for parts"

    It was worse condition than #1 but made a deal so $53 with freight, tax.

    Needed a through switch and control cleaning and lube, eventually came to life but VERY odd and deep symmetry issue in current source of the integrator.
    Finally found a flaky Schottky diode in the bridge, VOILA! Working 100% also in cal...was quite lucky....

    HAVE AN ABSOLUTELY FANTASTIC DAY!

    Jon

    I bought the cheapest NanoVNA-H for about 35 CHF delivered.
    Didn't expect much, but the device looks quite reasonable.

    It has cleanly shielded inputs, a working SD card r/w and a surprisingly large battery (1300 mAh).
    It has a MS5351M instead of a SI5351A (https://www.qrp-labs.com/synth/ms5351m.html).
    HW version: 3.6_MS.

    I am rather positively surprised.

    Nuclear power plant simulator!

    https://store.steampowered.com/app/1428420/Nucleares/

    Spent 3 hours last night, did produce power, but could not for the life of me get the stream generators, turbines and condensors balanced.  Ended up running out of generator fuel, then battery power, so I "Sigh quited" and went to bed.

    This I figured it out, will retry tonight.  The trouble for me was I was either not condensing enough or I was putting far too much of the steam heat into the condensor and not enough through the turbines.  So the condenser overheated and the generator stalled.  To fix that you can inject water into the condensor, however, doing so "shocks" the system and kills all your steam pressure.

    Epic!  It completely lacks any nuclear physics or chemistry.  So you don't need to worry about the make up of your main loop water etc.  No PH, Gas content, dissolved salts, conductivity and what not.  Nor do you need to deal with moderator poisons.   Basically the only properties of the coolant it handles is temp, pressure, flow rate and phase change.

    The core is very simple.  The only primary controls are a single control rod position setting.  Single fuel bundle.  Flooded pool type.  It does have a pressurizer which is the bain of the operators existance, it is the dog you need to keep feeding when you change any power settings.  Or you can just ignore the steam alarms and "Yolo" it. 

    That later doesn't work when you fire up the reactor to critical and THEN notice you didn't fill the pond and the pressurizer has boiled dry.  Many flashing red lights! Then you have to figure out how the hell you are meant to refill the pressurizer while watching the core temp, 112, 116, 120....  "Low coolant level!", "Low steam volume", "No electrical voltage", Lights go out, batteries kick in, lights come on.  You get a bollocking from teh AI.

    The steam generators I think I have figured out a little further.  It's also a lot easier to run 3 loops than 2 or 1.  The plant doesn't have the power to easily overwhelm 3 prim/sec loops.  Well, not as easily.  The different loops also tend to respond to each other so if one gen is a little low on liquid volume and one is a bit high they will slowly thermally balance themselves.

    The hardest part to get right is the much finer balance on the core pumps, steam gen coolant pumps and the condensor.  You can run them in so many different equilibriums it's easy to get lulled into a false "knee" and think you are max power when in fact you are just dumping 20% of your power into the condensor by running the steam gen loops to hard.

    I'm on day 15.  I have all 3 steam gen loops up and running.  30MW peak, tends to only need to run around 20MW to meet all objectives.  The issue with that and 3 steam gens is that they are just as sensitive at the low end of running as they are at the top end.  Turn your back too long and the stall out and drop pressure.  So tonights plan is to experiment with 2 gen loops overnight and see if I can bring the 3rd on during the day without "dropping all the spinning plates".

    I learnt that if you are to shut down 1 of the 3 loops (once installed), do NOT shutdown loop 3.  The schematic shows it is the only loop that maintains the pressurizer.... ooops.  I got it all shut down and the red lights out before the entire steam generator dropped to 0% integrety and started spraying steam everywhere.

    Can't afford to service the reactor AND replace the steam gen.  So on day 20, I am banking what I have learnt and returning to the start of the game.

    I don't know if it was the pressurizer which caused the gen to fail, or if it is something to do with how I shut it down and isolated it.  I'm leaning towards the former.

    Nope.  It doesn't mean it's a nice safe reactor either.  it has a "feature" such that when the control rods get above their red line, they become sticky and only move at about 20% the normal rate.  So if you pull the rods out too far, you might not get the back in before you run out of places to put the heat.

    Much more likely is a 3 mile island incident with the pressurizer vent values emptying the pressurizer and causing an uncovering or steam explosion.

    It's a game.  When your plant starts to run behind on maintenance, all manor of failure and high ware characteristics emerge.  My favourite is, after 50% wear the reactor vessel develops a thermal leak and begins to boil the pond water away.   When the steam gens wear or lose integrity their parameters shift oddly so it's hard to keep 3 in sync when 1 or 2 of them are going daft.  Same thing for all the pumps.  Command 50% and get something close dependant on wear/int.  At even 94% integrity the pressurizer 'self adjusting' stops being effective for anything but a few degrees of core temp and generates constant transient steam alarms every few hours.

    It's why I'm starting again.   It's the game element of managing your "compliance" to the grid for "points" while being as frugal as possible with when and in what priority you do maintanence.  Running the reactor at 360*C and the loops flat out with the core at 95% rods for the early game and producing 2 to 3 times what you were required to... is just going to wear out the reactor faster than your "points" are coming in to fix it.

    A pair of Proton wheels with super rolling hubs modified to be 8 speed for my 90s road bicycle.
    With this kind of wheels, I can travel for +40Km with the same level of effort required by Zonda wheels(1).

    how can i say that? after 20 measurements on the same bicycle frame with the same setup, drinking the same things, eating the same banana when energy is low, walking the same roads, for no less than 200 Km.

    So, talking about average, if by using Zonda wheels after 160K I am tired and I need to stop, with Proton wheels I can travel for other 40Km.

    Love that  8)


    (1) they are not "Zonda G3", they are Zonda 90s version.

    What is the latest firmware version for this?
    (Where) Can I buy these rubber-keypads separately?
    What exactly is the hardware difference between Keithley 6517 and 6517A
    (in the specs I found so far about half settling times for the 6517 preamp at "higher" currents, slightly faster reading rate to front panel for the 6517, no alternating polarity ohms mode for the 6517, no conformity to european union directives specified for 6517)
    (@TiN, I hope it is O.K., that I used one of your images as reference. Please tell me if not!)?
    I prepared an animated gif for comparison, but with the upload only one frame survived :(
    Did anyone draw some schematics on the input section?
    Why does it assume Aug 4th 2023 to be a Saturday?

    Bought some ancient power supply. These were the capacitors in it, old enough that they are officially on pension for the one series pair, and well pensioned off for the other pair.Tested just for a laugh, and the one says it might be a capacitor, the other 3 are very poor diodes with high junction capacitance. Crusty Plessey capacitors, new long before I was born. But made in England, along with the germanium PNP transistors, and the diodes.

    Thank you! There is also a 2-component liquid solution on the market, which is much more expansive. Did not try either of them so far, only cleaning with alcohol.

    I got a cheap RF broadband amplifier (https://www.aliexpress.com/item/1005005704247436.html).

    Since my oscilloscope already contains a simple signal generator and I have a TinySA and a NanoVNA, I don't really need a dedicated signal generator at the moment.

    However, I thought it would be nice if the signal from, say, TinySA had a bit more amplitude.
    And that's what I can achieve with this cheap unit to a certain degree.

    It's not that I would recommend it for serious work, for that the amplitude drops too much with higher frequency and the signal fidelity..., but if you want to have some "steam" in the signal for little money, it's ok.

    In the attached image you see 30MHz from TinySA amplified to 6.5VPP.

    RJ45 crimp tool.

    Already got one but I acquired that before the recent trend for through-hole RJ45 plugs (as shown in the pix) so it doesn't cut off the wires like this one. Got fed up of slicing a finger when trying to trim them manually.

    There are many of these, hence why I haven't posted a source, ranging from 'gosh, that's a good price' to 'they have to be joking'. I imagine they are all the same and have the same faults - cable stripping is useless, the supplied trimming tool even worse. But they do crimp and cut off the wire ends, which is all I care about. And a bit smaller but still very usable than the traditional style of crimpers.

    Best 200 Mhz handheld oscilloscope in multimeter format, there are better tablets.

    It only cost me 22,247 rubles. Which is $225 todate. This same scope is $309 on U.S. market, plus 6% tax. At that price I wouldn't get it, but this low, $225, yes, I want it, I need it.

    The SDS1104X-E I bought in the U.S. for $413 plus 6% tax, people will bring it to me in September. Here it costs over $700.


    Thus far, the impressions are good. I like it.

    Shipping time is ordered August 8, received today August 14. Shipping from Moscow by Shenzhen Shengtai Tools Mall from Aliexpress.

    RJ45 crimp tool.

    Already got one but I acquired that before the recent trend for through-hole RJ45 plugs (as shown in the pix) so it doesn't cut off the wires like this one. Got fed up of slicing a finger when trying to trim them manually.

    There are many of these, hence why I haven't posted a source, ranging from 'gosh, that's a good price' to 'they have to be joking'. I imagine they are all the same and have the same faults - cable stripping is useless, the supplied trimming tool even worse. But they do crimp and cut off the wire ends, which is all I care about. And a bit smaller but still very usable than the traditional style of crimpers.

    I picked up a Klein from Home Depot for the pass through RJ-45 connectors.  I could care less about stripping or trimming, I just need it to crimp and cut clean, which it does. I actually like making my own cables now.  Still have my 2000 vintage crimpers, I keep it for nostalgia.  ;D

    I don't have a capability to test that claim. But there are plenty of youtube videos, 380 Mhz seems to be the last usable frequency --

    https://www.youtube.com/watch?v=ymGbcCWA0wY (https://www.youtube.com/watch?v=ymGbcCWA0wY)

    430 Mhz is the frequency at which signal can't be distinguished from noise.

    no dobut yours has a better Mhz/Price ratio, however, considering quality and reliability, with only 60Mhz of bandwidth, the best handheld oscilloscope in multimeter format is the MP720015 EU-UK  :D

    (edit: attached datasheet and user manual)

    Bought one for my "mobile lab".
    Paid 300 euro shipped with all the accessories and the DSO in a sturdy metal suitcase.

And a bit smaller but still very usable than the traditional style of crimpers.

    Ordered one of them as I have a small lot of cables to do with a new 10Gig run to the shed (buying that one already made, gel filled & shielded 6A) but then 2.5Gig so moving from 5e to 6 mainly. Locally patch cables or mid length ones are not a thing so a roll of CAT6 is coming too.

    Also added a tester because it sounds good 'in theory' TDR and NCV are a few things I don't have and if they work then it is still a fairly cheap tester. None of the cheaper ones appealed and the Klein tools stuff is a chunk more for less locally. https://www.aliexpress.com/item/1005004831870128.html?https://www.aliexpress.com/item/1005004831870128.html?

    Finished up going with OM4 fiber and a pair of SFP+ modules because it was cheaper than doing it with Cat6A and modules that would use more power as well :o $90 AUD inc tax and delivery. Still conduit and some fixing costs on top of this but I would still need most of that with the wire option.

      -builtin component tester
      -quick view for all measurements.

    All these options are not in my RIGOL MSO5104.

    I made an adapter using the terminals I removed from the old battery and a small piece of prototype board. It looks kind of ugly, but with this I think I can use almost any type of battery, which means I can save a lot of money!

    The shielded CAT6 is a bit of a fiddle compared to the 5E ones I have chopped up to test the crimper but the ones I made so far have got data going in and coming out so that is a start I guess.

    Two servo-linear-motors (hybrid, custom made by a company)
    - accept PWM signals with 16bit of precision on a 2msec pulse
    - controller by a digital controller with position feedback
    - able to pull/push up to 500N!!! (~50Kg!!!)
    - only 500mA of stall current!!!
    - 6V powered
    - gear-ratio 1:1000 reduction (yes, it's *VERY* slow)
    - alluminium metal case with steel reinforcements

    cost me ... a lot: only 90 euro each, but they only have 2 units and it's out of production :o :o :o

    Decided it wasn't worthy of a thread/review but the Cable Tester from a few posts ago turned up and it does what it said on the packet  :-+ All the Cable signal and handshaking tests work really well, NCV is good too.

    The TDR functionality seems to be around +-2-5% based on a range of cables and I so far cant fool it to do non twisted pairs and read correctly so there might be some 'take it apart' soon. 2-3% on mid length cables and might be I got ripped off on the 100m roll but I am not unrolling it to check  :-DD

    My shielded crimping skills or lack of still need some work and the multicore multi stranded 'floppy' wire is harder to feed into the connectors but after that works well. Still waiting on the boots to hide the average crimp work.

    Brand new Campagnolo C-Record/8SP hubs for a new typology of self-assembled wheels: class retro vintage!


    The first and second generation of C-Record hubs are the best ever made! Sure, they came with cones and balls require periodic inspection (every 5000Km) and grease changes (every 10000Km), they suffers terribly in case of rain, and if you leave the house and it starts to rain cats and dogs, as soon as you get home they absolutely need to be dried (with a hairdryer set to minimum) and lubricated, and there is also an "oil port"  as well as there is a "out hole" on both dust cover crowns to let out, thanks to centrifugal force, any water that accidentally enters, so you also have to worry about it, also the front hub is equipped with a pair of "dust cones" (aka "dustcaps"), which require a special (very expensive) "dustcap puller tool" extractor.

    Modern hubs are compleatly different, since 1998 they are sold with sealed bearings, which are more robust against dust and water but less efficient on lateral friction when the wheel is not perpendicular to the ground but has an angle, typical of the trajectory when cornering.

    My bike is hybrid: it uses classic (1983-1994) hubs for the wheels, and modern (1999-2005) sealed bearings for the bottom bracket.

    NOS, in great condition, ready to use, they normally cost around 250-300 euros.

    I was lucky enough to find a pair that had been sitting for over 30 years in storage for less than 120 euro.

    Unfortunately, they are completely seized and don't turn at all. It's the fault of the fat that has aged badly. They must be completely disassembled, degreased, cleaned, regreased, and then the must be adjusted.

    A bunch of impulse items from Aliexpress.

    Somewhat recently Aliexpress introduced "Choice" which gives you free shipping + a 14-day delivery time. I discovered that using the phone app that you seem to get additional offers in the form of $2, $3 and $4 deals. The catch is that your cart needs to have between 3 and 10 items and you can only buy qty 1 of the specially discounted items. However, you can place multiple orders.

    Below is a montage of the stuff I bought.

    I have a shelved project not started to build a silent audio device power supply.  My initial KiCads where laying out the batteries.

    Then AliExpress offered me one already made for £11.  Don't mind if I do. 

    It's a ~30V LifePO4 battery pack with balancing leads and possibly multi-taps on DIM connectors.  Plus the main 30V output rail with I think a 5Amp fuse.

    Purchased an Eico 250 VTVM on a flea market for 10 bucks.

    Very very minty condition. Almost no scratches aside from tow on the large coil meter front. No rust, only dust inside. Even the tubes in it look very new. Gotta change some original axial capacitors though before I even dream of plugging the mains into it.

    Might make for a very nice Analog Amperemeter should I bundle it more permanently with a shunt resistor. Would free up my Keithley 2000 from such tasks.

    My review is:

    Desoldering station: fantastic! best tool I bought, it helped me do stuff easily which previously were very hard.
    Solder wick: also nice. all previous wicks I got were Chinese which never worked! like not even with flux or 480 degrees iron. these are the real deal.
    book: looks unique but still to be read... it is on the tips and tricks side of things rather than traditional textbook.
    pcb holder: kinda ok, since the board sometimes slips. very nice for the price.

    I decided to add to my pile of cheap DMMs by getting a Zotek ZT-702S. USD55 before tax, and with free shipping.

    Buying an oscilloscope-and-DMM also lets me delay buying a decent 100+ MHz scope. Since most of my purchases are of moddable and/or hackable cheap products, I'll undoubtedly get a scope where I can, um, "unlock" its frequency limits. I've seen a few models on the forums that qualify.

    Last month I bought a Schneider 78005 soldering station at my local Harbor Freight store with a USD10 discount. Its tip and element seem identical to the USD15 irons with built-in temperature control that I get from Aliexpress. So, I found it amusing that Popular Mechanics said it was the best overall soldering station of 2023. https://www.popularmechanics.com/home/tools/a41977866/best-soldering-iron/ (https://www.popularmechanics.com/home/tools/a41977866/best-soldering-iron/)

    There are NVMe options depending on your SBC of choice   >:D PCIe3.0x4 not as fast as a full blown board but this SBC stock also runs dual 2.5Gbps LAN.

    True.  The SBC I ordered, which is thankfully a little "swiss army knife" of a thing and will find many other purposes.  (Zimaboard 832).  So it's weeky little intel low power CPU, 8Gb of DDR4, 2x1Gb NICs, 2xSATA3 ports, and the gem, a full 4x PCI slot.

    The thing to be careful of here is the speed requirements on the buses becomes the bottle neck once you move into the latest gen storage hardware.

    A Gen4 PCIe x4 M.2 NVMe drive is capable of over 6Gb/s on a single drive slot.  It will use 4xGen4 lanes.

    I don't think there are any "micro form-factor" boards with even a Gen3 bus at x4 for the M.2.  Most are Gen2.

    The AliExpress NAS boards for example, which everyone is using to builds "NAS" boxes, has an M.2 slot yes.  However it's only a 1x and it's only PCIe gen 2.  People are then putting 4x or 5x SATA adapters into that slot and then putting a ZFS RAIDz1 or RAIDz2 on it full of SSDs.

    A Gen2 X1 M.2 Slot isn't even capable of maxing out 2 SSDS.  It will be limited to around 1Gb/s and will never saturate the Gb links.

    5x HDDs spinning rust... sure.  But who actually buys HDDs these days?  Unless you are a video creator with massive 10-50Tb bulk storage media drives... SSDs are the present.

    One of the purposes I have for the "storage focused server" is in service container volumes over the network to the VMs/Containers/Docker stacks.  I have yet to determine if this is best done on a "Checkout and commit" style pattern so volumes are then located with the pods/containers locally, but managed centrally and sync'd back home periodically... or...  direct live NFSv4 shares with multi bonded links so that the NFS server and Virtualisation host have EXTREMELY fast access to those "mirror'd" pair of M.2s.

    The later may result in just too much network "chatter" and too much instability, but I need the hardware in place to even test out which I prefer.

    Fun stuff.  I tried a dual M.2 Riser card in a Dell Optiplex and got 1 drive.  Expected.
    I then tried the same dual riser card in a brand new B550 Asus Prime board and ....  1 drive.  No 4x2 bifurcation support.
    I then tried it in the X570 Crosshair Hero 8.  Along side the Gtx3080 in x8 mode and it bifurcated it and gave me 2x full Gen4 M.2 drives.

    I promptly put those into a "Windows striped volume" and use it for "Steam games" and video editing scratch drive.  It's completely unreliable and a single corruption takes out both disks, but it has "replacable class" media on it.  The speed on krystal disk mark is 11,700MB.s.  11 Giga bytes per second.

    IRL though.  Game loading and scratch driving produce a large number of "random access reads", which, surprisingly (?) will drop an M.2 down to a tenth of it's full speed at sequential.  I believe that is the DRAM cache on the SSD working at it's best in "read ahead" mode.  When you start hitting it with random access for single blocks, I believe it crashes out the cache on the drives and bottle necks them.  Put another way.  A game which took 1 minute to load of a "consumer 500Mb SSD", still takes 35 seconds to load on a supposed 11Gb/s M.2.

    Edit:  There is talk about games starting to be optimised for performance SSDs.  Previously game devs moved to "cabinet" or monolithical "dat" files to speed up loading due to seek times on HDDs.  When SSDs became the norm and the seek time went from microseconds to picoseconds, the became lazy and went back to "catalog" folder structures and millions of small assests.

    It seems they are having to go back the other way as gamers are realising an SSD/M.2 hit with constant random reads does not perform well.  With modern consoles getting M.2 this time round, the "talk" is in a redesign (again) or assest management to improve load times.

    I might be missing something, but how does the PCIe expansion fit? I mean, I can see there is a PCIe socket on the side, but all the cards that might fit look like normal PC cards with fittings for the case. But the Zimbaboard doesn't appear to have any way of securing a card, so it is hanging there in the breeze. Couldn't fine any cases or anything to solve that either - have I missed something or is it expected that this is just a dodgy don't breath on it hack?

    Swiss army knife, not chef's knife.

    People 3D print brackets and the like.  In my case it's very likely to end up in a corner collecting dust and not be bothered.

    However.  I do agree.  If you were to, say, knock this off the bench onto the floor, it will almost certainly snap the PCIe card AND destroy the socket, if it doesn't short the PCIe bus out and fry it.

    EDIT: The way I looked at it.  It's basically a near like for like replacement for a Dell Optilpex eWaste recon box.  Except it's half the size, half the power and twice the number of NICs.

    Still think they should put 2xm.2 slots on the back of it and stop teh SATA ports for the next version.  Assuming the pissy little CPU can actually shift data.  That remains to be tested.

    OK, thanks. I could find a use for it as it is, I reckon, but the PCIe connector just plays with my mind. Surprised they didn't make a backplane card of some sort to allow this kind of expansion whilst adding decent mechanical support too.

    SH72 soldering iron, I don't know why it's so underrated here on eevblog but after some use, I think it has really good value for the money (for beginners).
    I bought it on AliExpress for 17€ shipped and if you search you can buy spare tips for just 3€ (They are a bit light, but they are ok for small stuff).

    The tips are not the shortest (quite the contrary), but I have no problem with that. You should go with the BC2 tip: it has a flat head that permit good heat transfer and it’s good for soldering SMD.

    12-24V power up to 60W. I use it at 12V, and I can solder THT connectors fine. It gets power via a barrel jack, but I removed it in favor of a nice flexible cable.

    If you can up the budget by $8, ksger C210 for $25: https://www.aliexpress.com/item/1005005519807256.html (https://www.aliexpress.com/item/1005005519807256.html) Performance and ergonomics will blow you away.
    Mostly small size tips though, more for SMD.

    The current I see at 12V is 4.5A so 54W. You can raise the input voltage up to 20V and you'll easily hit that 70W figure (as its a resistive heating element).
    But... the C210 tip from JBC is rated for ~20-25W?, so you're already massively overdriving the tip at that point. There are settings for current limiting in the menu, though they don't seem to work that well and there is no manual to explain them.

    Went thrifting today, found a pleasantly plump old DC power supply, looks like 1970s vintage, a chunky black box with two meter movements.
    A Zurich (I know the city but not the company!) DPS-712M
    But they still make em, looks like.
    http://www.zurich-electric.com.tw/zu-p01.html (http://www.zurich-electric.com.tw/zu-p01.html)

    Didn't really need it, but it has speaker terminals for output which might be handy for bare wires, and for running my LiPO charger.
    25$ but hey, no shipping and this thing's heavy!
    Also thrift stores charge more these days.

    the intended use of the chinese insulators is to hold mains voltage wire
    as in 1930s vintage style house electrical wiring.

    Now think about my specific situation: I assembled a set of wheels with hubs from 1980, new hubs never used for 40 years which have the grease hardened to the point that the hub is stuck, so you need to extract the dust caps, remove the balls, degrease and clean everything, grease again, reassemble, and tune.

    The problem is that, while for hubs from the 90s and 2000s there are "standard" tools both for extracting the dust rings (conical caps are no longer used) and for sole spanners to dismantle everything, with hubs from the 80s you need that "special" extractor to remove the dust caps, without ruining or scratching them.

    So, when you have to finish and test a bicycle (unique titanium brazed frame, made in 1977, with modern rims "classic style", and 1980 components ... unfortunately not mine, I assembled it for Ania), and you don't have the tools... you're in the same situation as the bottle of water at the station bar, that's why I offered 50 euros, which is still a lot of money for that tool, and I would have seriously paid that amount to save time, but at 150 euros it's a resounding:  I'll build it myself  :D

    Have no fear! I found this fun wireless S-Video/VGA extender, that also seems to convert the S-Video to VGA as a bonus.

    Got what I considered a decent deal on a range of generic Chinese soft multicore wire. My current lowish remaining stash is stored in plastic bags in a tub and is always a nuisance to drag out. The 10 and 12 AWG can stay in the bags and the rest of it will move to small spools like my other general hookup wire. Under 2 weeks to my door https://www.aliexpress.com/item/1005005048098404.html (https://www.aliexpress.com/item/1005005048098404.html)

    Fired up Fusion and now off to the Laser Cutter to make some storage/dispenser racks for them. Still need to make racks for my hookup spools now instead of the vertical stack that gets toppled frequently :palm:

    https://www.amazon.de/dp/B087XNQK7Y/ (https://www.amazon.de/dp/B087XNQK7Y/)

    FM reception is really bad there, and this one does an excellent job.
    Easy to use & setup , nice remote , and with BT too.

    I actually have the parts for a "HiFi Berry" laying around , but the wife would never be able want to use that one, she'd want a remote & a LCD.

    A bit pricey, but worth it .. To keep my THX Certified "Work horse"

    How is the output voltage ripple on these?  I have a current probe that takes 9V batteries that I always forget to turn off so I'm replacing batteries on that thing way more than I want to.  But I'm pretty sure that probe would be sensitive to the output ripple if I tried to run it off a supply/dc-dc converter instead of direct from a battery.

    Has anyone looked at the output of one of these?

    The noise on its output looks terrible. The upper part of the picture is measured with a load current of 10mA, while the lower part is measured with no load.

    Sorry, I don't have any current probes so I can't do the test you're expecting. However, there's no noticeable problem while using it with my Keysight U1253B, Fluke 117, and 83V multimeters, except that its slightly larger size makes it a little bit difficult to fit into the U1253B.

    As a sculpture it's representative of the late '90s early 2000s for me. I have a great affection for miniature things like this, especially speakers. These are real nice.
    No cables, no remote, it powers up but the fluorescent display is very very dim. The volume knob is motorized so that's cool! I also love the style of the top loading CD.

    Just re-cal yourself, it will be way better than factory anyway, as you can add additional cal points. There is a script to automate the procedure, manual takes way too long.

    This is sort of NCTNICO's fault I ordered the FNIRSI 58  ::) My now 5 year old 3A logger was out of legs for the job from when USB capped out at around 2A.

    Also gave me a reason to pull out my now 5 year old baby load (35W, 25V, 4.5A) to test the new toy with. On special if anyone is in the market currently for a baby load but for a simple bench one or throw it is a gear bag well worth the few $ https://www.aliexpress.com/item/32677950277.html (https://www.aliexpress.com/item/32677950277.html)

    I haven't looked at the Pro versions in details yet, but for the other DSLogic products, the software is open-source: https://github.com/DreamSourceLab/DSView/tree/master
    and based on libsigrok, so you should be able to modify it to your needs if it doesn't support a particular feature. Now we'll have to check whether DSView supports their Pro versions or not, but I doubt they would have developed closed-source software while the core of their products are using open-source software. So, should be pretty flexible.

    UT622E LCR Meter

    Why?
    - Deep check on all those salvaged components.
    - My Keysight 34465A (specified up to 100 uF by the way) takes ages measuring capacitors over 220 uF. I.e. useless above around 220 uF. This is the only booooo I have with this instrument I am using for 8 years now.
    - I love test equipment.
    - Make a definition file for test controller. You will have to wait a few months for this.
    - Make a definition file for Profilab, if I ever get around making one.

    What I dont like about the UT622E so far:

    I don't think you're going to find a handheld LCR meter that can measure in the GOhm range. Pretty much every single LCR or impedance analyzer out there maxes out at 1-200 MOhm impedance. There are impedance analyzers out there that can measure up to 1 POhm, but they have a price tag that makes maxed out Keysight ones look like a budget option (also, those only go to 40 MOhm). I have them at work for material science (characterisation of insulators, they might very well be in the GOhm region).

    Check out my latest green hoarding thrifting beauty: AKAI CS-F21 cassette deck in full early '80s glory. 11$
    Oh god I love this thing.  Metal extrusion front panel, great three-position mode switches, heads look great,  I love the polished contour around the REC LEVEL knob.
    Dolby B and C, manual type selector. I guess the auto sensing stuff came later on. And it's super clean, no funky smell.
    I don't know if it works, I like it more as a sculpture.
    I gotta go back and find the remote. As if!

    I couldn't resist opening up this deck, clearly it was well-cared for. The belts are fine, and the mechanism has a serious metal flywheel in there, I like it. No Tanashin here I guess.
    There's a small envelope taped to the chassis with a hand-written note in French that states "belts replaced May 16th '97", with the old belts in the envelope.  :-+
    I like this PCB, it exudes serenity. ^-^

    Impedance, not resistance. 1 GOhm DC resistance is relatively easy to accomplish, measuring that sort of impedance in the kHz range takes a bit more effort.

    At kHz it is really pushing it. 1POhm is 1fA at 1V or ~6000 electrons per second. At 100V and, say, 6kHz it is only 100 electrons per each period of the excitation frequency. At the same time you need to avoid a direct capacitive coupling as much as possible. Hmm, sounds like fun  8) .

    The UT622E has a virtual COM Port via USB.
    Its the software supplied with the unit which has the <COM 10 limitation.

    Communication (SCPI) is documented in the manual and works as advertised.

    I have one of the first Bus-Pirate versions, which I used a lot at the beginning to have something that spoke I2C, but I don't use it anymore.

    Today I'm looking with great interest at the latest version bus-blaster, very unfortunate as a project because they haven't even dedicated a page, but it could be very useful as E-Jtag MIPS on MIPS32-r2 targets, like my Atlas eval board.

    I still have to order one, and then... well, then I have to experiment for myself, because there's no one around who can give feedback  :-//

    So I can't be the only person suffering TEA issues,

    So last weekend I spotted something I had been looking for so I put a comedy bid for one, then spotted a better one so put a comedy bid on that. So now I own two Current Clamp Meter attachments for a multimeter. A i410 and i1010. The i410 is rated for 400A AC/DC with a spec of 3.5% + 0.5A for DC and AC, whereas the i1010 is rated for 600A AC and 1000A DC but at a better 2.0% + 0.5A specification. Just need to keep an eye out for a low range one for those moments when I want to measure the resting current or at least know the leakage current on vehicles.

    Found this almost featureless thing while thrifting, all it has in the rear is a round 4 pin power connector with no indication, a USB B socket, and a grille with a fan ...

    Chunky + heavy + metal + 5$ = buy

    It's pretty big and heavy, I thought maybe a USB chargeable battery back up. I figured I could use the aluminum case to maybe make something. (yeah right)

    But noooo, inside it's two 500GB SATA WD hard drives hooked up as a 1TB drive. Of course with USB 2.0 it'll probably take 5 days to fill ...

    Of course the power pinout is the reverse of the power supply I have so it'll have to wait.

    Meh, so worst case 5$ for that enclosure is not bad.

    Also, the Flipper website says demand for the units is very high. This makes me wonder about the Aliexpress listings. Are they a scam? Or perhaps they actually bought Flippers and are just flipping them?

    It was just flipping early on when the demand was high and there was huge hype. Its died off now. There will still always be some premium for aliexpress, since they will ship to some countries the official store does not. But let us know if you find some interesting feature.

    Not today, but three days ago.
    I bought a uses Dell Precision M6800, with new battery, 240W power brick, 32GB ram, new 512SSD, new 1TB SSD and backlit keyboard.
    The battery was new in 2015.
    The power supply is 180W.

    I checked expressly for a model with backlit keyboard.

    Here is the picture of the backlit keyboard:

    And here's a video that shows how one can't see it when in broad light.

    https://youtu.be/3GO4Wpbm8QI?feature=shared

    Now, the seller told me it will change the battery and the power supply and 'we will find a solution for the keyboard'.

    I used to call Advantest R6243 poor man's SMU, now I know that R6240A is the REAL poor man's SMU.

    I love that it's lightweight and compact, unfortunately the VFD on the one I got is so dim that it's almost impossible to read in daylight.

    Is that display reading 20K (well, 19.9982) and the resistor is marked as 10K0000?

    Thank you for your input.
    But how can you tell?
    From the picture its not possible to tell, but there are stickers of another language on the alphabetic keys. It's not an electrical problem, but an optical one.

    See the video

    You are correct in being very cautious. But in this case the stickers are covering the international English language keyboard with a different language. So there is a reason for that. The power supply, albeit underpowered seems a legit Dell product (the store claims to take ex-leasing laptops from businesses). But yes, we know very well how easy it is to fabricate labels in China.

    My guard was low because a friend of mine, who I trust, had bought a similar product and was quite happy with it.

    Trust no one.

    Just ordered 2 of those E27 neon flicker lamps.

    (Attachment Link)

    When I was a teenager, going outside to walk my dog I'd sometimes commit minor acts of vandalism. One evening I stole a regular lightbulb from an entrance to a staircase.

    (Attachment Link)

    Next evening I saw an eerie mesmerizing red glow there. When I got closer, I noticed that instead of a lightbulb, someone screwed in a flickering neon flame lamp, like the ones they have in churches. Of course I stole it too  :-DD   I liked its gentle neon glow so much, I've put it into light fixture in my bedroom (it was the one with 2 circuits and 3 bulbs).

    Telling my parents I'm going to bed, then long nights of staring at Trinitron CRT monitor, running Visual Studio 2005 on Win XP, in a room dimly illuminated by a stolen neon lamp. Then can't wake up in the morning, being late for school and falling asleep during classes. Man, those days are never coming back.

    Anyway, I'll buy some E27 fixture, switch and put it on my desk to keep me lit during those long December nights when I'm coding.

    Depends on what they mean by "spirit" , the opposite could be:
    dullness level
    reality level
    sober level
    mortal level

    The fluid inside is alcohol. So without it, I'd just call it a "broken" level.  ;D

    It can technically be either a level or leveler depending on use. If you use it to *measure object horizon position, it is a level tool. If you drag it across a pan filled with sand to *make sand plane even, it is a leveler.
    Looking at the design and construction of this specific item, it is a level. Too cute to be a leveler.

    When it's made in the Far East then it's (hopefully) level.
    When it's made in EU or US then it's leveler.
    When it's made in Germany then it's levelest.

    Found some very 1980s mini speakers.
    I don't expect super audio from these but I love the look, the little knob, the square speaker.
    Inside it's pretty amazing too. Not what I expected, but then AIWA were a good brand.
    edit: the audio is shockingly good. Like, no bass, sure, but you can hear it, the highs are all there, the mid-range is fine, they sound great.
    Not at all what I thought when I saw them at Goodwill. I had some crappy powered speakers in the 1980s, they weren't like these!

    I took advantage of the Black Friday deal on a Rigol MSO5074. It will be a Christmas gift from my wife. It will be a companion to my LeCroy WavePro 960 2 GHz scope, a great machine which lacks certain features that have become common in the two decades since it was manufactured. The Rigol will fill the gap with serial protocol decoding (including rarely found I2S which I will use), bode plots, logic analyzer, and a few other things. All those features imply a certain 'upgrade' to be made asap.

    T7 transistor tester with fake chinese chip! These days you can not get a better one. Guys at 4pda said this version can be modified with real ATmega, so the next thing is to get ATmega chip and modify it. Obviously no transformer on board, so no way to test zeners above certain voltage, just have to deal with that. The thing lies left and right the way it is now. Gonna get ATmega and modify it according to these instructions -- https://mysku.club/blog/aliexpress/97109.html

    The difference might be attributed to the fact that the M-Tester uses a DC pulse and the Hantek uses 100 Hz AC to measure capacitace. A nice trap this. Note that the values stated on the capacitor only apply to a capacitace measurement with pure DC. So both your measurements will yield results which might not agree.

    I know how to do that. Most resistors are going to be 1K and 10K.
    Now how do you design analog filters with certain cutoff frequency.
    Or set up an output of a DC-DC converter to the right voltage.
    In every design there is the odd value component.
    This just unloads the mental task to keep track of whether or not I have the part.

    That's the idea. It's either this or drawers upon drawers of resistors, I am hoping to avoid that.
    I'm still missing 0402 and 0603 RF parts, but I don't think random aliexpress parts would be good for that.

    No, no. Of course I wouldn't assume that someone wouldn't know how to consolidate BOMs.

    I wrote "BOM deconsolidation" :).

    With part kits like this it makes sense to spread the values used, if you do the soldering yourself: e.g., if your schematic needs five 10k pull-up resistors, then use 8.2k, 9.1k, 10k, 12k, 15k to deplete the kit's resources more evenly across all the values.

    I still like my lambda seven segment displays ! prefer Hp analog dials but the seven segment is good! the LCD displays like that are not liked in commerical labs. the TFT or whatever modern displays increase cost too much and provide little utility.

    Things to consider. Apparently there is a 9 watt model, well, you should look for that instead and get a 9 watt model. Because 3 watts are not awesome, they do their job, but I want a street light brightness. Also, do not get new black model, get a regular black. New black is shorter and not as bendy, though it looks better.

    Nah man. Can not replace your ring light. Can add to the ring light, 100%. To get better access you need barlow lens. Use 0.5 or 0.7x. On photos 0.5x


    I also have 0.7x, and I get plenty of space with it, but my back hurts after using it for extended periods of time. After I get a better chair (I have a kitchen stool right now) I could use 0.7x. You should get both 0.5 and 0.7 at the same time. You will use them both.

    Or, do the same thing poor guys like me from Sochi do, buy a cheap 144 LED light and modify it. Give it 18 volts @ 750 milliamps, and then buy 5 mil LEDs and replace all 144 3 mils to 5 mil, and alright.

    I know. Five PCBs are PCB 4 EUR including shipping.
    If you add a resistor to the assembly, the assembly cost they add is like 15 EUR, they upgrade your shipping method to DHL for another 15 EUR. Charge import duty on the assembly costs and the shipping costs for another 15 EUR. So that resistor is 45 EUR. This is like the cheapest you can order something from them.
    (Why do we have to pay import duty on a service, nobody knows.)

    I was talking about the second resistor, which is virtually free.  ;-)

    It's annoying that the cheap shipping doesn't apply to the SMD assembly service. The import duty don't apply to the US, and sometimes on checkout they give a $10 discount, not sure why, but yes, the first resistor is very expensive.

    Well, goodies above I bought some time back, just posted pics here when it arrived. Today, just now, I bought this.

    (https://i.imgur.com/OQUEUl4.png)


    This is my 3rd attempt. Prior I attempted to buy this cam from here https://aliexpress.ru/item/1005006098771600.html and here https://aliexpress.ru/item/1005006098771600.html both sellers are crappy and did not send me the camera. I guess the price is too low.  :-/O (we kinda trade in our own currency, so it goes up and down and sometimes it makes no sense for them to sell you stuff because of price, the system is new and rusty it is still being oiled and stuff  :palm: ) That's earliest november 17th. Nothing happened.

    With points after 11.11 it cost me $117. There is no customs for orders bellow 1000 euros. So I'm waiting. I hope this one sends it. Either way I'll update when it arrives or something happens and he cancels.


    My microscope is ready and waiting for it.

    (https://i.ibb.co/pKYzBNy/IMG-3757.jpg) (https://ibb.co/c84FSRL)


    I am expecting both output at the same time, HDMI and USB. So I'm getting a 90 degree HDMI adapter, and then when it arrives I'll get HDMI cable and USB cable, both locally. It's cheaper this way than from china.

    Sensor is IMX334, I've done a lot of research before selecting this cam.

    I snagged an HP 5370B for about 1/3rd the ridiculous price people are asking on ebay.  Works great and is pretty clean.  I have a pair of 5371s, that are nowhere near as precise, sound like jet engines, and other TICs but the 5730B is sort of the gold standard for time-interval work.

    Happy Holidays!

    I got a very similar model to that a while ago for a family member with a 120V food mixer.

    By memory the wires inside were a bit dodgy (damaged insulation) so I touched a few bits up before handing it on to them.

    Import duties and VAT (if applicable) are set by the government. Only the admin fees differ by courier. Fedex has a surcharge if the customs declaration has more than 5 or do line items, which can add up quickly if there's lots of different items.

    Yep, indeed dodgy inside. But the biggest problem is how old the thing is, turns out mains hasn't been 110V in Canada for a long time. Oops. It's closer to 125! So the "220" output is more 250.
    So that sucks. I have a Variac but now suddenly this setup is getting very large.
    I just wanted a quick way to power European computers and peripherals. I think 250 is too high.
    But that transformer is 40-50$ plus shipping so I'm still ahead if I just use it as a bookend!

    Technically, it's still within the 230V +- 10% tolerance.

    But yeah, you don't generally want to run things at nearly the max allowed voltage, especially given that many devices state that "240V" is the max allowed (not that they'll fail at 241, again).

    Those magnetic transformers are very nice (and have some weight in them, too), but these days, I guess, the default way to go is to use switch-mode transformers: AC115->low-volt-DC->AC230, using, unless otherwise is acceptable, a "pure sine wave" inverter for the output. It also has an added benefit of being able to power it using a battery.

    I intentionally bought a couple of faulty hard disks,  512Gbyte Seagate Barracuda, with a level of failure that does not mean a totally unusable disk but a disk with several bad sectors, heads and everything else working perfectly.

    I expressed this particular request to a seller who charged me 1 euro for both HDDs, and 14 euros for the time he took to perform the tests I requested of him on something like a dozen HDDs, selected from a basket of 100 HDDs to destroy.

    moral of the story:
    +01 euro for both the HDDs
    +14 euro for his times
    +15 euro S/H
    --------------
    =30 euro to have them at my house  :o :o :o

    Super happy, these two defective HDDs are *exactly* what I need in order to perfection my userspace RAID without the need to model (in python, or in C) a faulty disk through a virtual HDD.

    Yes, I noticed it's not even in their official retired collection. Not sure why. I bought it when QA was just starting, I think. Maybe they're not proud of some early products, or maybe they don't want to mention them as it's a category they don't make products for anymore, so they don't want to be bothered by customers asking for them.

    The power supply is a QA300. I was not even able to find any article on it on Google. That's odd. I swear I have one. ;D
    (I can take a picture of it if anyone's curious.)
    The supply's still working fine. It's a programmable low-noise supply, single channel, with USB connectivity (not powered by USB). I remember there was an issue with early versions, I had mine replaced because it tended to turn off the output by itself for no apparent reason, but they had sent me a replacement unit promptly, without me even having to send mine back, and the new unit's been working fine. The LCD display has oddly developed some burn-in over the years (I left it on for extended periods of time at some point), but otherwise still good.

    Don't know, they probably decided that this wasn't a market for them.

    bsudbrink is right! It is called »Feuerzange« - a utensil for preparing »Feuerzangenbowle«

    »Feuerzangenbowle« is usually prepared in autumn / winter, when it is cold, wet and dark outside.

    You take a pot, fill it with a dry red wine, season it with sliced oranges and lemon, cinnamon sticks, star anise and cloves, then warm it up on the stove (do not cook!).

    The most important part: Invite a lot of friends!

    Finally, when everyone is gathered around, take your »Feuerzange«, put it over the pot, place a »Zuckerhut« (sugar loaf, lit. "sugar hat") on top, pour some rum - at least 54% alc. (100° proof and above) and light the rum on fire. 80% rum will give you the best result in regard to caramelization of the sugar!
    While the sugar slowly caramelizes and melts away, keep on pouring rum with a scoop if necessary, enjoy watching the flames and have a splendid time anticipating the finalization of the »Bowle« together with your friends.

    When the sugar has completely melted away, fill into cups and pass it to your friends.

    Fun fact: The »Zuckerhut« has been the defacto standard for trading sugar from medieval times up until the 19th / early 20th century.

    If those batteries were 12v's, I'm sure I could find a use for them. Those 6v's aren't a "starting" type of battery either, they are "deep-cycle" only.

    I picked up three of his APC's. He said that they worked but the batteries are flat. I peeked inside of the one to the left (Smart UPS 900) and it has IC's dated from the early 1990's in it. They are all in great condition. The black one is a Back-UPS XS 1500 and still has the plastic wrapper over the bezel:

    The K2000 has no fails on the internal tests , no blown caps or earlier leakage signs , the front/rear switch is fine , FW A19 and is spot on except the ohms ranges - they are all reading 0.54% high - i think the current source needs a little attention . The Toellner PSU works 100% and the R&S unit seems to work fine too , but i have yet to check the exact numbers . . .   :-+

    I also got me a new Siglent SDM3065X from the Batronix Advent calender sale on the 17th just for fun  :-DD

    I was told to take this McIntosh with me too. It's a C28 Preamplifier. It has a face-plate which suffers from delamination on the backside that's fairly common, excellent shape otherwise. I think a new face-plate hovers around $250. Not sure if I'll get to this project. It visited the performance clinics in '78, '80. and 1982:

    This one. The tip shows a linear movement of approx. 1.8mm in total. With it, a core is moved in a coil with center contact. I think that should be part of an AC-bridge. Does anyone have some lock-in-amplifier like code for an arduino or similar that can help me to determine the position of that core?

    This link shows a typical layout with an oscillator as part of it. The block diagram might get you started too. https://www.mitutoyo.com/webfoo/wp-content/uploads/Mu-Checker_2215-1.pdf (https://www.mitutoyo.com/webfoo/wp-content/uploads/Mu-Checker_2215-1.pdf)

    There is some detailed schematics for other brands out there but I haven't come across any for Mitutoyo.

    Thank you for the pdf and the good wishes! So far, my guessing was not bad. If you have a further links for detailed schematics at hand and would share them, I would be happy to have a look. I am wondering, if it is worth to open a thread and show what my oscilloscope will see at the output of the bridge or if this is of minor interest to others.

    You could try dropping Robin Renzetti (Member Robrenz) a PM he has done as much playing with the Starrett Brown and Sharpe amplifier that I can think off and might have some clues on the Mitutoyo?

    Several other videos on his YouTube using the Amplifier so have a look around there as well.

    You can measure the usage, maybe 25W per cam and 50W for the NVR? So 160W total ish. 8hr on a 100Ah battery maybe?
    If you plan to use them for a long time look into LiFePO4 12V batteries, they have come down in price. AFAIK they should work...

    I've been getting bare copper wire from CAT6 cables for the past few years and now I'm tired of the stripping process. I used tinned copper wire like this in the 20th century and the experience didn't seem that bad, maybe it wasn't stored long enough.

    you usually come across a roll thats corroded, 90% intact and then when you wanna replace it for 100$ its like no metal does not go bad.

    I don't even wanna buy it commercially for a lab, for the sake of the future. Only in a factory.

    honestly, store it in a container with some dessicant. Better yet, wind a small spool and store the rest with oxygen absorbers and dessicant in a vacuum bag.

    Like literarly at work I can see you having to incorporate it into a procedure for doing whatever, then like 5 years later someone talks crap about your work when they try it because they still have tons of the stuff.

    Received the miniature drill press that I bought earlier for drilling PCBs and whatnot.

    [attachimg=1]

    It's a good example of saving costs where appropriate while keeping the critical things done right. There's literally zero (at least as far as visual and tactile inspection goes) play and axial eccentricity in the essential parts.

    The motor feels so-so, but it can be replaced, if necessary. The actuation lever is cheap-ass, and the included PSU feels the same.

    Very quiet operation. Should be perfect for working on hobby stuff at home, especially for the price.

    Why will you have to make your own? 99% of applications you can get away with using LCR tweezers and <100kHz.
    A test fixture would only be needed for either very precise applications or some sort of low production scale binning.

    that's no joke I hate companies that don't provide good hardware because you just know the software is so fuckin bloated and dodgy now that you need very good computers for good workflow. Actually get something done instead of shamming with computer crashes!

    good pc means you have a boss that expects the unexpected and minimum rquirements pc means your boss is gambling with your success because he only uses wordpad and thinks its still DOS

    that complaint your employer likes to hear that the work is too easy is only true if the hardware works.

    I have seen that before. The lowest of low end hardware gets given to a engineer expected to work miracles with complex design software while the boss is busy shamming by making 15 meetings per day where they discuss management issues over coffee.

    then like 2 weeks before the end of the year long project you hear him asking 'what was that software we are using again?" :-DD and the hilarity that occurs with big excel sheets when they don't realize how slow it gets :-DD |O :wtf:

    flange repair kit to deal with cracked flange (didn't know about until old toilet was off)
    handle for dryer door (Amazon)
    iphone 7 plus (eBay) (iphone 6s touchscreen stopped working after being dropped one too many times)
    iphone 7 plus case (Amazon)
    iphone 6s screen replacement kit (clicked on the 30 day free Amazon Prime trial when I ordered this)
    new washers/etc for bathroom sink faucet (Lowes)
    bathroom sink faucet handle (Amazon) (set screw tap threads on old handle stripped)

    (edit)... and one more thing I forgot. Well, I didn't purchase it, but I got it. COVID.

    To counter the rants on who gets the best computer stuff (there is a pet peeve thread), I was pleased when I worked on IC design at Motorola around 2000 that they gave the layout contractors very good setups. They had the biggest monitors and sufficient memory/etc.  It was nice seeing something done correctly instead of the frustrating situation mentioned.

    I found this bargain at my local hardware store for less then $19AUD.
    its a brand new 2 speed cordless hammer drill/driver drill sold without a battery.
    having been sold out of them.  so I got the discontinued 12 volt brushed DC drill as is.
    not lightly to venture beyond my 12 volt power source.
    I added my own quick and dirty modification.  as I do not own a 3D printer.
    this hammer drill has a low R.P.M. geared setting I often need for light hobby work.

    Unfortunately, the function generator doesn't have the external 10Mhz ref. input option.

    I have never seen a Tenma version of that power supply. I have both Tektronix and BK versions. There are small differences in output specification. I don't know if those are from actual hardware differences, slight changes over the years, or maybe just Tektronix de-rating out of caution. I have never had both taken apart at the same time, but they use such jelly bean parts if there is a hardware difference it's probably the transformer.

    So I've been stuck at home for 2 weeks recovering from COVID. Ran out of coffee (among other thing). Ordered some green so I'd not be out of fresh coffee if run out again. Hadn't roasted in a while. Roasted each of the three types I ordered into second crack. Tomorrow I'll try them drip just to taste the difference, and espresso, which is how I make my coffee regularly. When I used to roast years ago, I found that I liked the coffee better if I let it settle a few days after roasting; but I need my coffee NOW, so tomorrow I grind some. It isn't roasted as dark as it looks in the picture. When I used to roast for drip, my go-to favorite was Guatemalan Antigua, and I also liked Sumatra and Java. Knob on the popper is a dimmer in series with the heating element to lower the heat. Without it, this popper roasted WAY too fast. I made my selections based partially on low price. Not familiar with any of these, so it's a crap shoot.

    Out of Coffee  :scared:

    I started with a bowl and heatgun as a popper load was never enough  :-DD The popper I did get for a play actually ran slow out of the box and they are a mixed bag of power and like you did can be modded including a taller chimney to help keep the beans inside.

    Day old is a bit lively and your flavours haven't developed fully but on a lighter roast for brewed 3-5 days is about spot on. For Espresso or if you like a darker roast then 5-10 days is about right for most.

    For anyone else tempted attached is my quick and dirty poor mans guide to roasting. Most of us have what is needed already and Green Beans are not to hard to find in smaller quantities.

    How long does it take to roast the beans in that?

    20+ years ago I used to roast in this popper all the time. When I first tried it, it would be over done in less than 5 minutes. I put a dimmer switch in-line with the heating coil, assuming it would just burn up, since the dimmer said "600W" and I think the popper said 1200W. I just tied it onto the outside of the popper since I thought it was a temporary experiment. Lo and behold it worked, and eventually I put the dimmer inside the case. I can adjust the heat from too hot (as it was), to too cold (never roast). I have it set to a point where 2nd crack occurs around 9 minutes. Back when I did this as my regular way of doing coffee, I would buy green beans from a local roaster for I think $3 a pound less than he charged for his roasted coffee. I was the only coffee drinker in my house (kids all young). My primary motivation for roasting was that if I bought a whole pound of roasted coffee, it wouldn't be fresh enough for my tastes when I got near the end of the bag. I generally drink a morning and an afternoon cup. That's all. I grind enough for a few days, which for my tastes is fine.

    Later I changed my coffee habits and started drinking espresso. I couldn't figure out how to roast anything that I liked as well as Starbuck's, so I gave up roasting. With medium roast, I could roast such that it tasted the same to me as the local roaster's coffee. I'm thinking now that for espresso I roasted too fast and too dark. Starbuck's is really dark, and when I roast to that color, it just tasted burnt.

    I know I've read your thing in the past, but I'll have to read it again. My popper doesn't have any issue with the beans coming out of the chimmey. I like how the chaff just get blown off as it roasts (I do it outside), and it stirs itself. I'm glad you mention the longer sitting time for dark roast. I would never have guessed that long. I think I used to wait 3 days for medium roast.

    Post by: beanflying on January 21, 2024, 02:07:31 am
    With my Espresso blend I roast each of the beans separately and one of the beans in particular I roast 7-10 days before the others to let it settle before blending it together with the others. So that bean in particular you are drinking at nearly 3 weeks+. Indian Monsooned Malabar btw and only 15% of the roast as it has a very large personality  ;)

    The Plastic loader on yours is a lot taller than most of the modern ones so the beans should be ok without a chimney.

    One of the three bags I bought is an "Espresso Blend", but I have no clue what's in it. Website didn't say, and I thought I'd take a chance. I only roasted 1/3 cup of each. The Espresso Blend actually smells the best at this point, followed by the Java.

    ...edit... I was wrong. Just looked at the website and they have a picture which shows Sumatra, Ethiopia, Brazil and Robusta. I wouldn't think I'd like that mix, but we'll see.

    What an interesting thing! Do you have any specific plans for it or just playing (which is totally understandable)?

    ... it is possible to put the ic socket and LED displays in each other's location, solder - and then fail to recover the pcb (after doing one correctly first time:-//)

    A Melitta bean-to-cup coffee machine.  Cost around £250, it seems to be a model they are discontinuing soon as most places have no stock now. I'm hoping it ends up lasting longer than our previous espresso unit which managed 3 years but struggled with anything other than very well ground coffee.  In the end that one died because despite occasionally descaling it, the heater block became permanently scaled up and the high pressure hose just burst off, spewing hot high pressure water all inside the machine.  I probably could have fixed it but would need a new block which didn't seem to be sold anywhere.

    That is a very good machine, I have a similar one, compared to a Krupps I had before: coffee is better, much lower noise and easier to clean coffee grounds

    I took the train early in the morning, four hours later I was there, in a remote place, to pick-up the bicycle that I was looking for years!

    Exactly that model, made with Dedacciai tubing for the Atlanta Olympics. I found it semi-abandoned in a cellar - as the previous owner said - it was his father's bicycle in the 90s (passed away during the COVID pandemic). So, I paid for it, removed the dust, degreased the derailleurs and the chain, cleaned it thoroughly, re-greased it, inflated the inner tubes, and I was ready to go back home with a new bicycle!!!

    Eight hours cycling, 190km, two stops  :o :o :o :o
    (powered by liquid caffeine and two red bull cans)

    I am really tired today, but very happy  :D

    Every pack has a unique ID and when some chargers fail to start charging after 3 insertions of a pack they lock it out.
    The trick is to know about boosting the one cell that gets drawn down by the battery circuitry to a level the charger can like and accept it to charge.
    Many tradies moved from Makita lithium tools because of this.

    All works correctly, the tape type sensor works, the thingy lights up behind the cassette, very stylish, just needs a dusting and pots need cleaning, that's it.

    Picked up a pneumatic solder dispenser.

    [attach=1]

    Was meant to have a 24V external adaptor, but the unit I got was unit that took 240V with an internal transformer.

    Built quality was pretty good overall, pneumatics inside were solid and fixed well. 99.9% of the internal wiring was decent with wire that was rated well above the operating current.

    The only problem was the internal earth wire was a 1mm (maybe a little smaller) wire that was soldered to the fused input socket and then the other end floating around the transformer housing. Replaced that with a decent wire and verified all the metal work was earthed.

    Unit works well with no air leaks.

    An Upduino 3.1 FPGA board and I2S amplifier and I2S microphone. I plan to play with microphone arrays and this seems to be a good fit. Also look for free verilog tool chains and landed hapyly on[attachimg=1] Apaio, easy installation and easy operation.

    Arrived today, a cheap DC switching supply...
    Good display, good display/output accuracy, slim fit.
    Available in three versions, 0-30, 0-60 and even 0-120V, this is the 120V version.

    These Jesverty thingies are interesting. Basically
    I am in the market for dual 0-120 V 100 mA
    (maybe even with a bit more umpf)
    lab supply which will not cost an arm and a leg.
    Intend use: High voltage Opamps. Since these Jesverties
    apparently do not have a control input of some sort :palm:,
    I would have to improvise to gang two such units.
    Almost there. Maybe some day these things will sport
    an USB control input. :popcorn:
    Anyway, thanks for the heads up.

    I found a hp3456a in working order.

    I LOVE mine. 

    Not only is it gorgeous to look at but the math features are amazing; specifically the "(X-Z)/Y" and "100(X-Y)/Y" functions.

    Although the meter does not offer a current post, you can first measure a small shunt (via 4-wire) then store that in register Y (STORE, 8 buttons). Attach probes across the shunt then enable "(X-Z)/Y" via MATH,7 buttons to show current directly!

    Also, I'm currently exploring the "(X-Z)/Y" function to directly read ESR!  By (a) setting my FG to produce 1Vpp +0.5Voffset 200KHz square wave, 50R output Z, (b) the cap under test across the FG output, (c) a 100n cap (A/C coupling) to the 3456A set to ~V, (d) Y register set to the magic constant 0.006400, (e) then enable "(X-Z)/Y" via MATH,7 buttons to read out ohms directly.

    Need to sort 10K resistors? Just punch in 10000 STORE 8 to save 10000 in register Y.  Enable "100(X-Y)/Y" via MATH,8 buttons, then proceed to measure your resistors.  The display shows % error directly.  Easy peasy!

    Can't wait to buy a bunch of thermistors to play with the THMS*C function too.

    I got a Ti-89 Titanium used for $20 Canadian, and immediately flashed it to os version 3.10 using Linux TILP. Also I continue to mess with an Odroid C1+ that I got for $20 used with a 16GB SD card. I am still looking into it but it seemed to fail with certain SD cards on cold cold boot, but seems to be working with a certain SD card so far.

    (laughs) Good guess.  Actually, we have a software feature in our cellular network drive test analyzers (ROMES/TSMx) called "NPA" and it does stand for "network problem analyzer," but that's not this :)

    https://www.rohde-schwarz.com/us/manual/r-s-romes-npa-user-manual-manuals_78701-117121.html (https://www.rohde-schwarz.com/us/manual/r-s-romes-npa-user-manual-manuals_78701-117121.html)

    We do have a scheme for at least the first letter of our three-letter product names:  F for spectrum analyzers, S for signal generators, Z for network analyzers (get it?), C for communications testers, etc.   N normally is used for power supplies (Netzgerät), so that might be a clue ... although this is not a power supply :)

    We're launching it in a few weeks, so I'll be able to talk more about it then.  Every time the FedEx driver drops off a new instrument, it feels like Christmas morning to me, so I wanted to share what (little) I could.

    Thanks! I had a second hand K2000 too, and really liked it. Though it started to slightly drift out of alignment with everything else in the lab.

    Getting a full calibration done for the K2000 would cost more than what I paid for it, so I decided to bite the bullet and get the DMM6500. Very happy with it so far!  ;D

    I also bought the DMM 2015 used, but from the service of measuring technology, so I have it adjusted.
    I would also buy one, but I have to replace the oscilloscope first, so I'm saving up, I'd like an SMU 2461 - but I'd have to sell my body box for organs  :palm:

    My tabletop circular saw (https://www.aliexpress.com/item/1005006128820581.html) for cutting PCB material and whatnot has finally arrived!

    [attachimg=1]


    It's got everything it must have, including a vacuum hose attachment.

    Just like the mini drill press (https://www.eevblog.com/forum/chat/what-did-you-buy-today-post-your-latest-purchase!/msg5259588/#msg5259588), this saw is clearly built down to a price, but at the same time it was designed by someone who knew how to do it properly so as not to compromise the actual usability and allow for an easy repair and upgrade, should it be needed.

    I've already cut some boards, and oh boy, what a vast improvement over doing it by hand, you can't even compare.


    The PSU is quite a brick -- at least on the outer dimensions -- and notice that they used a generic case sold for DIY stuff, suggesting that it's manufactured in small batches. I haven't yet looked inside it, but probably I should. It didn't blow up on first use though, so it should be fine I guess.

    [attachimg=2]


    p.s. the sticker on the saw case says "rated power: 96 W", so no, the motor is not a 240 W one, but that's fine and is enough for small hobby stuff. You wouldn't want to use it for thick wood or metal or any heavy work anyway.


    up: 5200 RPM on the saw disk without load. The sticker says 5000 RPM. The motor is nominal 12000 RPM (I didn't measure it).

    Just brought home a HP 7550A Plotter. The mightiest beast in pen plotting aside from the stylish 7580. Only thing missing is the paper holder for the backside. Anybody able to make some pictures of theirs so I can DIY my own?

    I also now own a Deskjet 650C I still need to get new cartridges for.

    Executed some instant buys on Wandel&Goltermann SNA-62 and 7 Service Manuals. I only wanted the former with the latter being a bit of a panic buy as I thought it would be the only one the seller will have for the single digit SNA range. As far as I know they share a common digital and in part analog base with only the downconverter inputs differing from each other greatly.

    I will scan these if possible. There is no digital resource for these anywhere.

    Could have sworn I had seen that tray several days ago somewhere.....

    Edit: I have the fitting auto paper feed tray and that one looks like it will fit there too. It has the correponding tabs at the back fo match the plotter's backside also.
            Anyway I will have to take it apart, clean and reassemble anyway. Paper feed is acting up and the take up motor for auto feed doesn't move at all.

    Here's another crazy one. I'm working on a Nakamichi OMS-7 CD player and I'm waiting on a drive belt from Germany. I'm thinking that I'm going to need a CD afterwards loaded with test tones so that I can check the CD player out when it's all back together.

    I realized that I don't own a burner for CD's. I have two computers but no drive that burns a CD.

    A couple of months ago I helped a friend move and he was previously an owner of a satellite streaming company. During this huge move, he was giving everyone all sorts of boxes of stuff he no longer wanted.

    I remember two boxes he handed me but I thought that they were external hard drive enclosures. Not!

    I dug them up and realized that they are two brand new external optical drives from 2012 and 2013 :scared:

    The part numbers indicate the drive the customer chooses to goes in them. Sweeeet :-+

    It's tricky to say if I bought it today, but FedEx dropped off another box from LCSC, primarily radial and SMD caps, with a few reels of resistors for good measure. The order took more days to transit from HK, than it did for LCSC to fill it.

    In the meantime, I've found a display unit at a reasonable price.  :)
    According to the date codes, I found inside, it might be build in 1987. Prices for the new units appear rather steep, but I have to admit, that at least my old unit makes a pretty good impression, also when you look inside. Appears to be a quality Japanese device.

    Not today, but Friday I bought a Bambu Lab X1 Carbon w/ AMS.

    I have a (very heavily) modified Creality Ender 3, the OG Gen1 from 2018, that I bought back then to see if I'd even be interested in 3D printing. While I have my Ender 3 pretty well dialed in now, it was no small effort. The cheap Ender series are great but are considered DIY printers that requires a fair bit of work. I've spent more on upgrades than the printer originally cost (multiple mainboards, dual Z upgrade, direct drive extruder, etc.). It taught me a helluva lot about printing and I have no regrets, but now I just want to produce stuff quickly without much tinkering. The X1C is amazing in that regard (at 10x the price, of course).

    It is very pretty, but shouldn't the motor be mounted so it's upright rather than hanging down? As it is, it would foul anything higher than the hole you're making, like raised portions of the part, fixings, etc.

    I've picked up a few things along the way as the stock was whittled away.  The exact close day is top secret but the manager told me that they'll but a sign up that says "last 10 days" when the time comes. I also won at the casino then. By the way, I want to take this opportunity to recommend the https://casinosanalyzer.com/online-casinos/revolut (https://casinosanalyzer.com/online-casinos/revolut) service, which I used the day before to analyze the games. By the way, I liked the explanation of the Revolut payment method. It seems to me very convenient and safe.

    The manager at my local Radio Shack says they will be open until the end of the month.  There isn't much left but a ton of batteries and headphones (mostly ear buds).  Oh, and HDMI cables.  A wall full of HDMI cables.  He also said that for their last 10 days they plan to have a bag sale.  Buy a bag for $10 and stuff it full of anything that fits.   I'm wondering what will be left and if I should stuff the bag with things for myself or things I can unload on eBay like cell phone cases and phone batteries.  I'm thinking I'll have to be there on the first day of the 10 days to get anything good.

    With as many ear bud headphones as I have had go bad, the wire breaking at the plug, I should fill a bag for myself and quit spending time on re-soldering the plugs.

    As for my purchases, last time I got a crappy clip on smartphone microscope that doesn't even work.  Shows an image about the size of a dime in the middle of my 5 inch phone screen.   Previous trip I picked up 4 rolls of kynar wire wrap wire and a tube of somewhat conductive ink for less than $10.

    Oh, I remember that excitement. I also bought a $10 bag there, and you won't believe it, but I found a set of cool potentiometers in the store, which I just needed for my joystick атв books, DVDs, CDs, games...

    I haven't tested it properly yet, only switched it on once.
    The motor runs smoothly and the spindle doesn't seem to "flutter".
    I will find out more with a test drilling.
    So compare the diameter of the drill bit with the drilled hole.
    Otherwise, the manufacturing quality is good for the money (67€).

    Nice, certainly in good order appearance wise and becoming few and far between nowadays.   :(

    I have both the 187 and 189 due to my garage being burgled decades ago. The intruders took a brand new 189 and the insurance company replaced it with a 187. I informed them of the difference so they sent out a 189 and refused to take back the 187 as the paperwork involved with the return would exceed the value.   :o :-DMM :-DMM ;D

It would be nice to have an ESD point on the base, but it can be easily drilled into it. The lens distort the light color, they are probably very cheap. Otherwise it's a good microscope. ~85 EUR.

    I had that in mind, yes.
    We once had a project that was developed at the end of the 60s, a DC/AC inverter based on transistors.
    They had to be selected for gain and Uce sat, and there was special measuring equipment for that.
    We still have them... ;)
    If I can find the transistors, that would at least be a valid comparison.
    Otherwise, I will test and comment on the device elsewhere, but this will only take place after the presentation of the power analysis function of the SDS800X HD, due to time constraints.

    It's not only for transistors, but pretty much for anything. An interesting device indeed.

    It goes way over 1 kV, it's more like up to 1.5 kV in reality.

    One problem is that it ramps up the voltage too fast, so fast that it fails to detect the breakdown threshold, and too fast for the display and the user to see anything meaningful on the screen if that happens. This is an issue for parts with Vbr on the lower side: I tried to measure, for example, a particular MLCC, but could not: it broke down before the device could sense it. Maybe only an issue with capacitors, though, need to check something else with low Vbr. Maybe a 12-volt zener? :)

    I wonder if it's possible to make that ramp slower. If the timing is set in firmware, which is likely, then the answer is most likely no, unless it's possible to download and reverse engineer it, but otherwise, if it's something like an RC network, then maybe.

    Maybe only an issue with capacitors, though, need to check something else with low Vbr. Maybe a 12-volt zener? :)
    No need for guesswork:

    That's a 5V6 zener diode all right.

    Those low-cost vises have convenient M5 tapped holes on top, perfect for DIY custom jaws, e.g. 3D-printed.
    I used a couple of pieces of alu and cut a little groove into the edges, making it handy for clamping PCBs (although it can only handle small boards).

    Well, of course I started with attaching the antenna and checking what's out there on air. This device has a rudimentary "listen" function and a 3.5 mm audio jack output, so I used it. Apparently it can decode both AM and FM, and that happens transparently: there seems to be no setting to choose the mod. type.
    Discovered that there's *a lot* still going on in the SW band, managed to receive something that sounded like Chinese (?!) at ~7.35-7.42 MHz, some apparently UK-based station which told a story about Her Majesty at 10-ish MHz IIRC, and a lot of others.
    That's fun, but to do that seriously I would need a better antenna and a proper radio, of course.
    Found some peaks in the ~195-202 MHz range, which are dedicated to radio broadcasting, per our regulations, but couldn't pick any voice there (but I need to retry during day time, as that time I tried it in the middle of the night).

    It's weird that it's not level-calibrated above 5.35 GHz from factory. Why? They expect the users to have their own 5.35 GHz signal source and use that. Well yeah sure I have loads of those sitting on my desk. Not that I really need to measure anything that high, was just curious if my 802.11ac WiFi signal would show up, for which level calibration isn't required anyway, as a relative measurement would be fine too. It didn't show up, though, maybe I was doing something wrong.

    The signal generator is rudimentary: frequency accuracy is so-so, jitter is terrible, and output level stability is questionable, but it still may come in handy if you need a RF signal and don't have any other generator. AM modulation seems to use what looks like a 3-bit DAC to set the amplitude.

    On the other hand, when I enabled the Cal output, the 10 MHz frequency accuracy there was really good -- from my initial estimation (via a freq counter with a known error at 10 MHz), it was very close, below 1 ppm, to my GPSDO, but I need to repeat this test with them sitting side by side.

    As far as its primary purpose, which analyzing spectra, it seems to be quite good, well, that's what it's popular for. What would I use it for besides checking what radio waves are out there? Can be used to estimate how clean a generator's sine wave output is. Or, I'm going to try to estimate edge speeds of the pulses produced by my pulse generator, which is faster than my scope is capable of, using the method described in tggzzz's blog (https://entertaininghacks.wordpress.com/2015/08/11/measuring-digital-signal-edge-rates-without-an-oscilloscope/), but I'm waiting for some feed-through attenuators to arrive first.

    Menu tree (https://tinysa.org/wiki/pmwiki.php?n=TinySA4.MenuTree) can give clues to what else can be done using it. I haven't yet dived into all of that.

    missed this part:

    I don't have any other SA, so obviously for me it's first of all an SA. But other than that... Portability, at least, and maybe something else.

    So yeah it's quite impressive. About 10 minutes after powering on, the 10 MHz signal on the TinySA Ultra's calibration output had only ~0.15 Hz (which is 15 ppb) difference against the GPSDO, then at ~40 min after power-on the frequencies became equal and then the difference became non-zero again and changed polarity. And I'm not really sure if that's not the GPSDO tuning its frequency, as it hasn't been powered on for long enough, either. I'll let them both run for a couple more hours and see if and where it stabilizes.

    The GPSDO is a TM4313. A cheap one, but should be more than good enough for this kind of comparison.

    One way or another, that's way less than 1 Hz difference at 10 MHz so far. Definitely very good.

    Update: so it stabilizes at about 0.3 Hz difference, which is 30 ppb, unless my math is wrong.
    Not sure which sign though. If I set the scope to trigger on the GPSDO's signal, then the TinySA Ultra's signal is moving to the left. I'm failing to figure out which of the signals is ticking slower in this case.

    ch2 (trigger: ch2): GPSDO, ch1: TinySA Ultra.

    I got myself one of these:
    https://www.radiacode.com/ (https://www.radiacode.com/)

    An RC103.  Awesome bit of kit.

    At the moment I am trying to capture a 24 hour spectrum in my kitchen, which I can then use as a base background for other spectra.

    After looking through the house top to bottom, I don't have anything more radioactive than the cat or myself.

    The background spectra is looking fairly normal.  Lots of low end noise, but clear "bumps" for Ra226 chains and K40.  That was just from a 1 hour spectra.

    I look forward to testing the mapping function.

    Other purchases....

    * A vile of broken uranium/vaseline glass (I have no interest in pretty glass ware!).
    * An ionisation smoke alarm, as all of mine are optical.

    If I wasn't on "that" list before, I am now.

    Bremsstrahlung sic Braking Radiation.  When an electron is forced to change momentum (direction or velocity) (aka braking) it emits a photon depending on just how fast your electron is going that can be xray or gamma.

    The tritium emits low energy beta.  These excite the coating to release light.  Those that get through collide with the glass.  Colliding with the glass electron field at some fraction of C, and some N thousand electron volts, causes a gamma emission.

    It's demo'd and explained here nicely:
    https://www.youtube.com/watch?v=O78dHmzHgP8 (https://www.youtube.com/watch?v=O78dHmzHgP8)

    I have measured mine with the GMC-500+ Gieger-Muller detector.  It also never seen any beta, but it did see the Bremsstranlung radition.  However, I had to leave the keyring directly under the detector for 12 hours with 12 hours either side just to see the very, very slightly elevated portion.  It increased the count rate from about 18CPM to about 19CPM.

    I have my background spectrum now, I will see if I can capture an hour with the keyring and we'll see if we can even see the key ring in the noise low keV noise.
