Children are very good--if marinated properly. :popcorn:


You clearly have read "A modest proposal", a satire from the 18th century, which I recommend everyone to read for a good laugh, it is short,


A MODEST PROPOSAL

For preventing the children of poor people in Ireland,
from being a burden on their parents or country,
and for making them beneficial to the public


https://www.gutenberg.org/files/1080/1080-h/1080-h.htm

Probably very interesting and as I'm Irish I'd have liked to read it but....

Why did this block occur?

A Court in Germany ordered that access to certain items in the Project Gutenberg collection are blocked from Germany. Project Gutenberg believes the Court has no jurisdiction over the matter, but until the issue is resolved during appeal, it will comply.

10pcs of 100k 0.1% mil hermetic wirewound resistors. Still in sealed plastic and waxed paper packaging. TC looks pretty good, <0.01% change over a 30'C temperature excursion from a quick and dirty test.

They should hopefully get the next decade of my Hamon divider underway.  :)


P.S. Any chance that someone has data on the ERG TSPR23 family?

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.

Sounds like a classic job for a 3D printer?

Yup, for sure a job for 1 of them.... I think!

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/ 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

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.

Just bought this thing:



I was planning to make me one out of scrap things lying 'round my shop but it was sooo cheap.

I guess I must modify it to make it real safe  ::)

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.

I have never found a need to be rough with cleaning my tips on my brass curls.  A gentle caress works well as well with Mrs GreyWoolfe. >:D

My HDE and NASE both have not wore out a single tip. And I'm the kind of person that cleans a lot.

A Mac Mini 2018 with i5/8G/256G, two 16G SODIMM sticks (thank you Apple), a Magic Trackpad 2, and an RX 580 eGPU.

And of course, a license upgrade of Parallels. I struggled a lot on deciding between Parallels and Fusion, but I eventually decided I don't need more than 8GB of VM RAM, so I'm okay with Parallels.

So far I have to say I'm very satisfied, as Altium among other Windows apps work very well in coherent mode.

Preview looks awful as macOS 10.13 onwards don't support non-Retina displays (mine are one 1080p and one 1200p) well, so text is very blurry. I replaced it with Sumatra running in coherent mode.

Otherwise I have no complains at all.

Saved this current/voltage source from the iron junkyard container this morning for €15
No idea if it is worthwile, just could not see it being destroyed.
First going to look inside for leaking stuff etc before powering up.

For that price, it's worthwhile for the controls and binding posts, not to mention the nice enclosure.

Attached a couple os photos to show how I made the connections in my ESD ground panel, using spade crimping terminals, washers, nuts and bolts. The head bolt inside the hole of the terminal does not interfere with the connection with that sort of terminal. Besides, to the bolt, a crocodile grabber can be used for extra or a simply a different connection type.

Well, thanks to re-reading that old Project/Lab Notebook thread that got resurrected, I now have about $70 worth of various notebooks/notepads, pens, pencils and markers on order from Amazon. At least I managed to resist buying that telescope which popped up as a recommended item.
