Thank you so much! I'm really happy with how it turned out! Though, looking back on it, there's a lot of little niggling things I want to improve, so I think I may do a version 2 one of these days!
That's not weird ! That's super cool ! I knew what you were doing, but didn't expect to see such a great build The timelapse was really enjoyable, love the music and the PCB design ! Once again, you did a fantastic work. I can't wait to see your next projects ;-)
Thank you so much! As much as I love breadboarding stuff, cutting PCBs on the mill with curvy traces is just so satisfying. I'm super happy with how the SR Flip Flop turned out and I actually have it sitting right below my monitor. I'm working on the next episode now and it should be a fun one (trying to figure out how a bit of old tech. works)!
It's quite ironic that you used three valves to achieve what could have been done with one low voltage relay, two LED's, two push button switches and one resistor. That would have used much less power and would have been much more compact. But it looks more interesting this way, and it will be more useful for your future projects. Thanks! 🙂👍
you could have used a light bulb if you used it as a annode resistor that way you can use a 12v or 6V bulb and make it more traditional but for the rest awsome project man you should make kits of this (I would buy one)
Thank you very much! I actually did try to use a 6V bulb as an anode resistor or even just driving it with a cathode follower, but the tube just has too much internal resistance. It's kind of like why output transformers are needed for tube amplifiers - tubes love voltage but don't move all that much current. And at 24V, I'm moving practically no current, haha. Thyratrons however move a ton of current and can light the bulb up effortlessly, but they come with their own set of interesting problems. Although, I would like to someday build a set/reset latch display piece using a 2D21 Thyratron, I think that could be really cool! Now making a kit could definitely be fun! I may dig into that idea a bit more once I come up with a completely hollow state design I really like!
@@UsagiElectric oke I didnt know you already tried it I myself have used a tube to regulate a motor (ecc83 on 12v) and it worked without many problems also if you ever make the kit I will buy one!
@@robot797 That's awesome that you used a tube to regulate a motor! It never occurred to me, but I imagine you can get some great control out of it. You've got me thinking about the best way to make a kit, I'll have to do a bit of experimenting and see if I can come up with something that works well!
If you ignore the desire for an all tube creation, for the moment, to power the heaters in 3 tubes on the 24v power supply, could you not put a resistor of appropriate value in series with the three tubes, to imitate a forth tube ?
Thank you! There may potentially be some audio related stuff in the future. I really like the idea of running tubes at super low voltages, so it would be fun to see what kind of tube amplifiers can be achieved at just 24V. I actually already experimented a bit with this in the past: imgur.com/T6fatuu I would really like to use some of my huge collection of 6CB6 tubes to build a low voltage OTL tube amp, but that's going to require a whole lot of learning and experimenting, haha.
This series has degenerated into a trip through work arounds for an absence of simple, everyday power supplies. If that’s the intention, it’s just boring. If not, maybe rebrand the thing and do it right. There’s a reason that VT devices don’t use oscillators to create rails. Can you see it? It’s got nothing to do with ripple.
