That is a miracle.l!

I’m still arguing with my one. The poor guy has actually been cut off by Hermes entirely so he’s down £120. So I’ve raised it with Packlink off my own back. Amusingly Packlink almost instantly refunded me the delivery fee minus insurance so I’m up £5 already. Wasn’t expecting that.

The UPS stuck in Germany is still under investigation. UPS have marked it as lost on their tracking though. Apparently the case times out tomorrow so will see what happens.

New arrival today with its older brother.
Nerd mugs!
I need a NASA mug😁
Edit, FYI the mug photo on the left is a micro photo of an LTZ1000

[BU508A]

I'm having two of the LTZ1000 mugs, they arrived yesterday (now they are in the dishwasher)

[BU508A]

That is a nice one that is!

Toellner TOE 8735-2
starting bid: 199.- Euro, currently zero bids.

And, as usual: NAWTS.

[capt bullshot]

That is a nice one that is!

Indeed. It's got 10 turn pots, not that digital encoder rubbish

There's another one, but the price is a bit on the high side (as all the other stuff from that seller too):

https://www.ebay.de/itm/TOELLNER-TOE-8752-Dual-Power-Supply-2x-0-32VDC-2x-0-5A-320W/254880538392

I used to have this particular model (8752, 2x32V) at a former job and I really liked it.

Was scanning the offerings from that seller five minutes ago.

My god, I bought the same one last year for 60€ and I was not sure if it was worth  the money   

This psu is really  nice. The only bad thing  is that all trimmers are multi-turns and if you have to go from 5v to 30v you have to turn the knob like a crazy.

It's been about 6 hours since my last post and I wake up to air temp about 17 F and winds howling in excess of 40 MPH. That gives an equivalent wind chill of about -5 F or -21 C. Clocks are flashing again so power must have dipped again at least once. And I can feel a cold draft in here. Welcome to March. 

Oh well. At least power stayed on and have heat. (So far). Many don't. And this wind advisory is in place until 13:00 hours today. (04:30 hours currently).

They say Spring is just around the corner. 

[beanflying]

At least this one seems like it is only a short nasty blast. Still not good with so many still getting over the last

I also have one of these but here is one in the USA  eBay auction: #392659657016

That was the first frequency counter I ever used!

From memory mine was ex PMG and there is some info online as to the history of their use.

Made some 4-wire test leads on the 3d-printer today. Nice to find shorts on pcb and to measure shunt resistors. Measures the difference between 2 and 3 cm pcb trace just fine on a 6 1/2 digit DMM.
Tips are cheap chinese pogo pins (P100-F1 or P100-B1 or P100-Q1)

[Specmaster]

I was sleeping and something woke me up. My box fan had shut down and restarted. Clocks flashing. We are having one hell of a wind storm here. Scanner is going nuts with trees down. As I was typing this power dipped again but came back up. Have to wait for my router to reboot.

And I log on here and see all that blue tossed in boxes. I r sad. 

If that smaller pallet were to be delivered to me you would never hear from me again because I would have died and gone to heaven.     

If that pallet were delivered to you, I, for one, would sincerely hope that we would still have regular reports from you on your progress, we simply cannot have super contributors going AWOL. The thread relies on the super contributors and their regular postings with useful items to entice the newer members on board.
I see there is also a reasonable amount of grey in those boxes as well, no doubt should they wind up at your place that they would soon be receiving a fresh new coat of Krylon Gloss Bahama Sea 

One other thing, I reckon if theey were to appear at the Med mansion, you'd be better off doing a swap of flats with your downstairs neighbour, otherwise with that amount of extra weight, you'd both be sharing the ground floor flat for sure

What about if I put a 10mA RCD to save my ass on the entire mains on my bench TEA.
Now I have a 30 mA but there is an angel on my right shoulder telling me:"Go for 10mA, go for 10mA...".

Yes sometime I play with 230VAC mains 

That might come around to bite you on the arse in terms of nuisance tripping. Aside from the cumulative earth leakage currents from a few SMPSs, you're quite likely to see excessive earth leakage on something you put on the bench to repair. An old Y capacitor made by everybody's favourite X & Y capacitor manufacturer comes to mind as an obvious example.

I have a 10mA on my bench (together with a 6A fuse), but only for the DUT. Hardly ever trips when not needed. But I agree, with the full bench on it it would trip too often.

The downstairs apartment would be perfect. 4 bedrooms, large living room, kitchen/dining room, and direct indoor access to the laundry room. However, there's a husband/wife and 4 noisy kids (one an infant). I don't think they would fit in my place too well plus they would be above me. Nope.

I recently managed to win amongst the heaps of worn out, over priced crap that eBay seems to have become of late, a rather tasty TMK 500, a  30,000opv DC and 15,000opv AC analogue meter. I have one of these buried somewhere under a few metric tons of bits and bobs from my Mums estate which I had to clear out a few years ago and still have to do the final sifting through. Anyway this one from eBay was listed as the ohms ranges were giving full scale deflection but unable to get anything on the other ranges.

Thinking that the movement was sound, the problem was more likely going to be either a dodgy contact or worst case scenario. a blown track on the PCB, which as you can see clearly was not the case.

Then I noticed that the switch contact was missing altogether, I'm not going to be able to get one of these as a spare, so now the hunt is on for some suitable material to try and cobble together a new contact from

If you move that amount of gear in upstairs, you'll be joining them downstairs before you reach for your can of blue, whether you wanted to or not, fact.

For these sorts of smaller jellybean counters it is worth trawling ebay.com for a cheap freight one. A few of mine were only $30-40 AUD for post. I landed the HP 5302A for under $100

If you're not blinded by the hp logo these are decent counters and they don't come in fugly cases. 

That does not quite match a HP 5314A. Same number of digits (7) but no level control on 2nd input and no ratio. More of a RF counter than universal. The 520MHz range is  plus but let down by 7 digits and needs the TCXO to be useful.
A 5315/6 A/B is miles ahead of the Fluke with 8 digits, reciprocal counting more functions, but only 100MHz.
The Fluke would be an option if you wanted a small counter for both RF and very basic function counting but other than cost a 3 input universal like a later Racal or 5316A/B with the 1GHz option would be a better counter overall.

The problem with these counters is a distinct lack of digits

Anybody on the east side of Canada looking for 1 ton of misc TE ? the auction is sitting at 200$ right now.

It's a good thing I'm 12h away. A little bit closer and I would probably had to rent a van to bring everything back home.

Dang.

I might m.. well, I shouldn't, really, but.. It's.. OOooohhhHh!

Oh God.

Brilliant! I can install it in my main var trafo that I use to repair mains stuff!!!

Well excuse me.  I didn't mean to imply that they could be used as a bench standard or any other fancy pants applications. Consider them the "3.5 digit" or quick and dirty measurement. Nothing more. Geez.....tough crowd. I think I'll fold my tent and go home.

Nah!---------unlesss you count the incandescent lamps that make up the readout.
There are six vertical columns with lamps behind glass lenses marked 0-----9.

If you are, for, instance, looking at a frequency of 191919 kHz, you read the first "1" from the second row of the first column, go up to the top of the next column for the "9", then down again for the next "1" & so on.
