Youtube hearted comments of Keri Szafir (@KeritechElectronics).

  1. There's a huge difference between genuine, fact-based criticism and smearing the company by lying. You nailed it.

  2. This is the best material on the Chernobyl plant I've ever seen! Great job. Staying tuned for more.

  3. You're going full-on CuriousMarc here! What a magnificent system and video. And the comparison with the AGC DSKY is on spot here. Same thought crossed my mind. Speaking of the DSKY... just look at all these electroluminescent displays - another feature these systems had in common.

  4. Whoa. I still can't stop marveling at the fact that they used typical M42 lenses for Zenit cameras and a mirror assembly. Mighty friggin' clever! A thing of beauty and a joy for ever. I've got a vidicon camera in my collection (Unitra Polkolor TP-K162), but the tube seems to be dead. I'll have to take a closer look at it. It uses C-mount CCTV lenses. Next step? Soyuz comms!

  5. Absolutely fascinating! I hope the war ends soon and work can be restarted. You're taking on an extremely challenging task, proper respect to you - I've considered you an equivalent of CuriousMarc on our side of the Iron Curtain, and it shows. The opportunity to talk with the original engineers and listen to their stories is priceless - go for it while you can, it's a race against the clock now. I'm glad you do it. Nice ferrite core shenanigans, haha!

  6. "Only a woman would choose nano" If I knew this way back when in 2012, I'd start transitioning much earlier! :D Religious wars suck. I didn't care about the whole Vim vs Emacs debacle and used nano, still do! Distro? I used Fedora (that was the workplace policy back then), I use Debian on my personal systems, I also sometimes use Mint and recommend it to regular users. Rock on, fellow nerd! :)

  7. 297 of Soviet style blinkenlights! A painstakingly thorough restoration of an amazingly well built panel. I'm so impressed that you can Keri on making videos in war torn Ukraine, despite all the adversity. Hats off!

  8. 2:30 there it is, the Garden of Eden Creation Kit... LOL Thing of beauty, joy for ever.

  9. That's a very interesting laptop! Some of the Soviet assembly techniques are the same as in the Lell PSR drum machine I restored; it's all pretty elegant though. I would never expect a Japanese display in a Soviet device though. Oh, and I saw a screenshot of Block Out! i liked this game when I was a kid in the early '90s with a PC XT/AT at home.

  10. The overgrowth is immense. Looking at the comparison really reminds me of The Upside Down in Stranger Things... only nothing is supernatural here. It's just a few decades without maintenance, nature reclaiming what was built by civilization.

  11. Ah, the things of beauty! The mirror galvanometer is just so damn lovely. Using photoresistors for limit indication is just brilliant - the only thing is that the alarm condition will never go off if a lightbulb blows, haha! But then checklists and other operating procedures were probably in place to make sure everything was in a good working order.

  12. Nice news on the SSH updates. While there's no problem if both client and server run a modern version of openssh, it could be confusing to connect from modern to legacy system (e.g. an OpenWrt router which hasn't been sysupgraded for years), but all can be done with some knowledge and google-fu. Hey, nice to see the creator shoutout! Who knows, maybe I'll end up there someday :D

  13. Nice restoration, well worth the effort! The beautiful simplicity in engineering :).

  14. That's a nice kit, kinda reminds me the "Construction" knockoff of a Meccano made in the GDR. I had a lot of fun playing with my brother's :). 3R12 batteries, becoming rare nowadays. Back in the '90s and beyond they were ubiquitous. Using a mains transformer's bobbin with some added L-bracket, you could even make a Ruhmkorff's inductor! :)

  15. Interesting clock, lovely VFD. I'd replace electrolytics and TACT switches if needed. Otherwise, it's built pretty much like the Lell PSR, pretty much in the middle or upper regions of Soviet everyday electronics build quality. All clean and not too shabby.

  16. Joy for ever!

  17. "Establishing battlefield control... Stand by. [...] Battle control online."

  18. A mighty interesting overview! I wonder if, and how, these developments contributed to the space program.

  19. Thanks for the debunk. I've seen the original video and it was just... too many things happening behind the scenes.

  20. LOVED the Matrix reference! Nice computer, and I liked that version of Tetris.

  21. Holy shit, that's meowsome - a real deal Hep Cat!

  22. Excellent video, thanks for explaining the reactor's construction! :)

  23. Ha! I didn't expect it, but I learned something new.

  24. Oh, for cryin' out loud... Don't even get me there. Soviet quality was all over the place, depending on the application. Military, scientific, aerospace electronics, test gear and pro stuff? A thing of beauty, a joy for ever. Good grade hi-fi gear? Possibly. Everyday electronics? Super dodgyyyyyy, as DiodeGoneWild calls it. At least it can usually be fixed... As for the icky plasticky stuff, I've got two Iskra 111 calculators in my lab, one with partially broken enclosure, the other one's box was too far gone and I used it to cut out a part that was missing in the first one. Both calculators are beautifully built inside and I decided to restore them, gonna make a clear acrylic box for the other one to showcase the lovely guts. That's SLT as in Soviet Logic Technology - ten years after IBM Solid Logic Technology. "And here's the meh-anism" haha!

  25.  @ChernobylFamily  and the Lell PSR drum synthesizer which was an incomplete product to begin with, the instructions manual had a chapter on MIDI interface which was never implemented in production units because of licensing costs.

  26. Fran-tastic work on that one! Much appreciated.

  27. Hey, greetings from another lab coat wearing nerd gal with Slavic origins :). Nice unit! I love how it's built, contrary to Allied computers, it's more mechanics than electronics, all so simple and reliable. Cool that you show synchros, as CuriousMarc just did a video on them :).

  28. Playing synths, talking science. These things mix soooooooooo well!

  29. Ingenious and interesting!

  30. Thanks for the explanation! I'll be repairing one of these cash registers RealSoon, I'm looking for documentation, teardown & reverse engineering videos. It may not be as complex as IBM Selectric typewriters, but getting it to work and aligning it is gonna take a lot of effort. Sweet kitty :)

  31.  @ChernobylFamily  Koko says meow too (Mewtwo?) and I'm trying to write it with him getting on my laptop :)

  32. That's a lot! Real deal old guard.

  33. Lovely and absolutely chaotic place. I once saw a video on that, not sure who it was (EEVBlog?). Another rabbit hole... 4:00 the note on replacing the SCR with a transistor doesn't hold water, it doesn't latch. 4:11 that was creative, made my day! 8:25 maybe make old school bomb duds out of them? A little Little Boy... They've been around only for 25 years? I thought that'd go well into the '70s :)

  34.  @axmanemployees8409  hey, thanks for the answer! Nice to know that - and what a goldmine of lovely vintage electronics you have :). Perfect for the thermionic emission nerds like me.

  35. Yes indeed. Pulling a knife out by an inch while it's been ten inches deep. Propaganda value? Priceless. CATS! How meowsome! I haven't seen these on your channel for such a long time.

  36. Nicely built, all conformally coated and while I'd say the LCD, slow reaction time and somewhat dodgy mechanical assembly may be the disadvantages of this dosimeter, all else is well thought out.

  37. Needs some cleanup and retrobrighting, 4:09 I see a big-ass paper in oil capacitor. I wonder why such an archaic and oversized component from the vacuum tube era is even there. 11:50 calling the manufacturer's technical support, haha! 12:04 lab assistant coming to help you. And 12:17 is "automatic medical systems engaged, caffeine adminstered". 14:10 yeah, no beauty, no joy. 15:00 inaccessible fuses, I know it may be a safeguard against unauthorized bypassing by the user, but c'mon - that's a BS in design and engineering...

  38.  @ChernobylFamily  don't tell me it was heavy fuel, haha!

  39. Hey, long time no see! I've been missing you. Congrats on 100K subs :) Are you keeping up with the Commodore? If so, I'll show you my overhauled power supply - that thing ain't failing you with a killer jolt of 12 volts on the 5VDC line! https://www.youtube.com/watch?v=0Ywvj78lhbk https://www.youtube.com/watch?v=jhiXJeBMYtU

  40. Truly fascinating! Love the complex tech in the backstage. This made me think of the behind-the-scenes works of the Apollo program mission control room, or the Electrosonic system installed in the Lenin museum controlled by an Apple computer.

  41.  @ChernobylFamily  thanks a million! That's one step closer to solving the mystery :)

  42. Hey, Mario now got a new quest: become a test subject for Aperture Science! Play mari0 then. In case you don't know it... it's Mario with portals and some typical Aperture puzzles - lots of fun!
