yarp. but at least it works. better to have a working GPU than a brick.

Not if you're being attacked by, say, a wolf...

...a working GPU would allow you to explore the various outcomes of any move you and the wolf make and produce nice parametric diagrams of them!

Only if it's attached to a working PC and monitor, which was not mentioned. Also, I'm not sure the wolf would be patient enough to wait while you wrote and ran the software.

We are far more patient than you think.  We will track and harry you for miles/hours before we deem you ready to be killed and eaten. ;D

But...but...but we got a really good correlation when charting the received damage in the first attack (as normalized trauma index) over the wolf's astigmatism and the relative angular velocity! Observations in the field show that we can make an accurate prediction valid for 62% of cases within 0.1 of outcome (on a scale from 0..1) for anything from a completely sharpsighted to a totally blind wolf!

To get away for a moment from charting and modelling wolves bears, I received a strange logic probe from IBM, complete with carry case in Burberry design. For technologies it allows to select between Multi, MST2/4 and MST1. Can someone with enough IBM product knowledge translate that into regular logic families for me or do I really have to dig through the accompanying, awfully small-printed, manual? It came to me for 3.-€ out of curiosity..if I never find any use for it, there is at least a interface cable fitting also on 5mm modular probes to dual 0.64pin.

I worked with MST2 on the S/370-3158 but that was 47 years ago and I'll be damned if I can remember the logic levels for 1 and 0. But I do remember the supplies necessary to power MST2 which was +1.250V and -3.00V but that's not going to help you. Sorry, you're gonna have to read the fine print or this link might help.

I dunno... If you watch the ads, you'd swear those GPUs are full of dragons and swords and machine guns and avenging angels and shit ...

Yes, but by definition, it wouldn't be a "working" GPU without those things. ;)

and before you say it... It's not a GPU when it's being used for mining or AI compute, etc... it's a coprocessor. :P

Yesterday I spot-weldet a banana contact tab of my differential probe against a grounded PSU casing with 230V AC.  :palm:



The welding is excellent.  :-DD

This little bit of accidental dissimilar metal welding got me thinking.

In electronics equipment construction I occasionally come across things that could be best done with a little bit of resistance welding of dissimilar metals. Things that come to mind include:

  • Welding a grounding strap (tinned copper type) to the inside of the lid of an aluminium case.
  • (Extreme case) Welding the bottom of a stud/bit of all-thread to the inside of a case for a fixing/grounding point.
  • Welding a spade lug to a case for a ground bonding point.
  • Tacking metal mesh (SS?) to the inside of a cooling grille (Al, Fe?) - both for ground continuity and even possibly all the mechanical support required.

That covers a range of oomph from "Probably needs some real welly and a proper discharge welder" for a stud you actually needed to have some mechanical strength to jobs you might even consider doing with a 'toy' like the capacitor discharge welders used to stick nickel strips on batteries (tacking mesh around a grille opening).

Obviously using fully fledged professional pulse resistance welders designed for the job is cheating (and expensive) but improvising with cheap automotive spot welders and battery tab welders might be an interesting area to explore.

Has anybody done any improvisations in this area? Any battle stories, bodges that turned out actually good,  experiments that failed disastrously?

[Cue stories from SeanB of exploits,  in typical South Eifrican style, with an infeasibly large stick welding supply and some innocent victim piece of equipment. :)]

Thanks I'll take a look. I've two or three complete welding handbooks/textbooks but they tend to be a little light on resistance welding, and of course on the most fun type of welding - explosive welding.

This is the defective power switch out of the Type 105. Discovered something interesting. On that brass plate it states 3A/125v and beneath it UL approval. On the cardboard is the maker's mark of "F" within a circle.

On the bottom of the plastic housing it is stamped 6A/125V and 3A/250V. Huh? I give up, which is it at 125V?  :-// Also again is the maker's mark of "F" within a circle. I have no idea who that maker is and they probably are no longer around anyway. It certainly isn't Switch Craft.
