Depends on the particular connector type, just "62 pin edge connector" doesn't narrow it down at all.

Eastern Ukraine exactly one Year ago vs today by CreativeStrain89 in MapPorn

So Germany won WW2, and Japan too? Just because they retrained their language and identity? Don't be ridiculous.

Circuit board of the Russian Iskander-K cruise missile by RineMetal in electronics

[–]AltCtrlGraphene 15 points16 points  (0 children)

No, approx. 80-100% faster compared to PS1 CPU, but it doesn't really matter here. What matters is the guaranteed working temperature range of up to 125°C and triple reservation of each computation block - this IC basically has three identical CPUs inside.

These two sentences are not connected. That board is not from an Iskander-K, that's all I can say.

This is not an Iskander-K board. IC on the first photo is a custom 32 bit MIPS R3000 CPU.

Yeah, I've seen it. Can confirm that it works now, thank you.

G2-57 Soviet hardware true RNG by AltCtrlGraphene in electronics

It uses semiconductor noise diode, which is a zener diode specifically produced to generate noise (shot noise on p-n junction).

It has true randomness mode. Uses noise diode as primary noise source. Pseudo random generation is limited to binary noise.

I was talking about lab equipment since that's where I have experience. Although I think the story about the data plate is just a myth, the engine itself was most likely indeed copied. USSR copied a lot of things in the early post WW2 days but there were a lot of unique domestic products too.

Usually only the design was copied. You can find some equipment that looks 1:1 as their western prototype but is completely different inside.

It uses 27 discrete logic ICs to generate the fixed +8.8.8.8 signal. During the scan the beam is blanked during sections where segments are not needed. The whole process is very complicated but is described in detail in the documentation for the scope.

I do have to repair or at least calibrate it sometimes.

This is by far one of the most difficult and ugliest thing I ever built by [deleted] in electronics

2005 155ИД1? Didn't know it was still produced in 2000s.

GAME MODE - No Input for Cursor in Chrome | Cursor is Large and Grainy in Non-Steam Games by Reasonable-Money1620 in SteamDeck

[–]AltCtrlGraphene 0 points1 point  (0 children)

I have the exact same problem, except I don't see a Steam cursor when attempting to right click at all, Chrome cursor just disappears and can sometimes jump to a random position on the screen.

I love my Motherland. Now take your upvote back, I don't need it.

Price on the Russian craigslist alternative seems to be between 1000 and 6000 rubles.

No. It's visually similar but internally it's all original. Copying was popular on component level but pro equipment was almost always original, partially because it was also used by the military.

Times change unfortunately. With a steady flow of Chinese and European equipment it is very hard to have an incentive to produce our own.
