Is she really a he? You gotta ask that question now a days because you never know.  :o

Ask Toyah that and I suspect you're likely to wake up with a crowd around you.  :-DD If you haven't seen it, you should watch Derek Jarman's "Jubilee", in which Toyah does a particularly psychotic turn as the character "Mads".

More than bananas. I think perhaps the full fruit bowl.

Toyah's 63, Bob 76, which is proof (as if it was needed) that just because you're old doesn't mean that you have to be a boring old fart.

I will get back to my regular boat anchor activities as soon as schedule permits. Maybe in 3 months. For now, need to finish sorting and organizing my components and misc H/W, almost done. Then I need to resume work on my Rochar Nixie DVM because it's in a millions bits all over the bench so I need to finish it, assuming I am competent enough to actually managed that, while it's still fresh in my mind, and before I lose parts and/or forget how to put them back together...

But if I can get those first few things I listed, done this year, that would be cool.
--- End quote ---

Ahhh, I had forgotten that you did in fact already have a smallish on your bench. So what specifically is the holdup on that; I know funds are short?

--- End quote ---

Not a money problem. It's just that it's a very sick puppy with numerous intertwined random problems, that drive me nuts. So after battling very hard, I managed to make progress, but there is still much to be done, and it was alwyas on step forward one step back... eventually rezached mental exhaustion and needed a break, I had no juice left for this thing. So I put it aside and switched to other things, then one thing led to another, and soon the Nixie DVM moved down the priority list. As the saying goes : " Life got in the way " !  :-//

So let me see... searched TEA a bit and found that my lat post / work on it was exactly 3 months ago. Since then :

- Acquired that rack mount Tek type 317 hollow state scope, so worked on that. Still need to finish it up by replacing some electrolytic caps.

- Worked on my HP 120B hollow state scope, CRT glass/ neck got broken and HV winding in the main transformer is arcing badly, no HV anymore.

- Embarked in identifying and sorting my components, what an adventure.

- Fridge thermostat needed replacement, so had to design and build an electronic replacement while trying to fit that "universal" thermostat my dad sent to me, which didn't quite cut it. Looks like the contact in it is seized closed, compressor runs all the time. So need to buy the proper replacement. But since my electronic timer works just fine, it's running off of it for now. Been a couple months now maybe... runs like a charm. I have now patented it and shall son start mass producing it for the low low price of 250 Euros a pop. Need to pay for the construction materials for my garage somehow, you see, and their prices have exploded. Not that they were cheap t begin with either.
Then the handle that keeps the small freezer compartment shut, inside the fridge at the top... broke. So now I can't use it anymore, bummer  >:(

- Dad finally, after 3 months, got done manufacturing customs plinths for my bedroom, and delivered them to me. So I then had that on my plate. Was a chore cutting them into bits as accurately as possible with the miter saw, then glueing them in place, then a bead of white acrylic to make it perfect and fill all the small gaps with the wall and at every joint between two plinth pieces. Then need to put two coats of paint but.... it's so fucking hot here with that heatwave, that even at 3AM it's still too hot to do any painting unless you are completely out of your mind.
So I am waiting for the weather to cool down a bit, if it ever does in the coming days, so I Can paint that.

- Friend gave me that stereo all-in-one shit box to fix, you must remember that, you helped with it... that cheap CPU that keeps the USB and SD card reader from working...

- Then I fixed that Matra aerospace 3 phase 400Hz 115V inverter

- And the other day I was given to fix that huge 55" smart TV to fix, back light problem. But the LEDs keep blowing like there is no tomorrow, so I told the guy sorry it's scrap. But then I searched a bit and found out that this TV is still sold toady and cost a freaking 1650 Euros, which pre-war would be about 2,000 US dollars. So I thought OK let's make an effort to save that fucking TV. Found new LED strips for that very TV for 45 Euros on French Amazon. Then found the same on Aliexpress for 14 Euros delivered... guy gave the green flag to buy that, accepting the fact that it might be wasted money if after reassembling everything we discover that the LCD got damaged  during disassembly / storage / reassembly. He was fine with that. So, I am waiting for these strips to arrive from China. Maybe in 10 days if I am lucky, in a couple months if not so lucky. We shall see.

I maybe have forgotten a thing or two but you get the idea : I got busy doing other things, and time flies ! I can't believe I stopped workign on my meter 3 months ago already ! Needed a break, for sure, but now it's about time to get back to it I think !!!   :scared:

Now THAT is the proper TEA attitude!  :clap:

Well, we look forward to your future exploits.  And I hope you find the courage to cull the herd a little for the sake of your sanity. ;)

Could it be a bad connection? I had this with my Solartron 7075, it was working fine before I got it, when it arrived it would only display even numbers (original cal seals were intact), I reseated some connectors & have had no problems since.

Let me guess, it has the same blue IC sockets as mine for all the ribbon cables?   

Bloody things can't hold on to anything. I'm seriously tempted to replace them all with turned pin sockets. After a journey from the UK to Sweden, just about every cable had disconnected itself!

Any chance the socket has enuf empty space underneath for one of those 2mm wide mini zip-ties?

What could it be?

--- End quote ---


It's a General Radio 2220 Bug Hound. Used for tracing shorts and opens in PCBs and wiring. also good for genearl circuit tracing.
Unlike similar tools like ToneOhm and the HPP current tracer probe it uses AC signals and a phase sensitive detector. I'm looking forward to using it in anger.
--- End quote ---

So non-contact, or just very tiny current so as not to blow up stuff like the ShortSqweek and Huntrons?

Both.
Non-contact probe with LEDs to show current direction and contact with +- 50uV or 500uV
--- End quote ---

Ooooooh... does indeed sound like the PCB debugging Holy Grail. I can see why you're so pleased to find one.  :-+

Damn you Robert! Damn you to... New Jersey!!! :-DD

--- End quote ---

Already been to New Jersey, more than once. I lived and worked in (old) Jersey Channel Islands for a while.

Just to annoy you more I paid £21.37 including shipping for it ($25.35 US) >:D

--- End quote ---

Damn!! You stole that thing!!   :o

I put mine aside to order test lead wire to re-do the rock hard self-stripping probe leads, now both are on the shelf waiting to be joined together.  That's one I should probably prioritize fixing.  (And I don't recall how much I paid beyond that it was a hell of a lot more than twenty five clams!)  Damned nice score!  <jealous>
