So I made a question thread last night trying to get a russian

what even is that

Nice job, OP.

The solution was

.9v on pin F+
F- shares neg with both power sources
5v on pin G
And I pushed 24v on pin A

The tube is an IV-15 (Russian DM160)

I really want to thank based engineering-anon for being very helpful last night.

>>51567625
Is that one of those things they used as transistors before semiconductors came about?

>>51567678
You're probably thinking of a vacuum tube. This is a VFD tube, used in logic circuits before LED's replaced them (around the 60's).

>>51567398
I have a few of them from my grandpa's old radio.
Can I make an amp out of them? How do I find their gain?

>>51567732
Oh right vacuum tube
Pretty interesting man

This is the pin layout

So what does that do that a normal LED doesn't?

>>51567936
Nothing. LED's replaced them in the 60's and 70's. It's the fact that it's a 1960's Russian logic-gate VFD tube that makes it exotic.

>>51567974
Oh, so hipster shit then.

>>51567986
About as hipster as admiring a steam-driven train.

>>51567986
>old tech is hipster shit
Bet you consider bulbs and segment displays hipster shit too

>>51567914
Why are there 4 pins op?
Did these serve any other function other than providing illumination?

>>51567398
Can we please have more electronics threads on /g/? Even if it's simple shit like this, everything is better than "Hurr look at the things I bought!".

>>51568139
See >>51567490
It's difficult explaining without explaining how VFD tubes work, but F+ is the filament, G is the logic-gate (0v for off, 5v for on) and A is the grid (the glowing blue part). F- is the ground

Interesting. What type of tube is that?

Agreed
I play around with microcontrollers but almost no one on/g/shares my interests

>>51568322
I'm an EE-student but I rarely have the time to do projects or just fuck around with stuff outside of uni. Obviously there are better places than this shithole to talk electronics, I'm well aware of that, but I'd like to see it improve.

Thanks ni/g/ger. Going to see if I can find some of these on Ebay.

/diy/

>>51568322
/g/ is mostly filled with kids and their latest toys, or weaboos talking about which cartoon lady looks best on their wallpaper

>>51567398
I was the EE student giving you advice last night. I took another look at it today and say /diy/ had given you a schematic. Figured it would only be a matter of time before you got it working. Congrats.

>>51568364
I just want to improve this place a little, I know that there are better boards and forums out there.

>>51568364
/diy/ is dead as fuck, and that board is more centered around the handi-man

>>51568364
OP here. I made a thread in /diy/ last night when trying to get info, and although I did get what I was looking for, I only got about 5 replies vs 40+ on this board. Both threads really helped me figure it out though.

>>51568372
I mentioned last night I was working on a tube project for a class. The due date is December 15th. If you check back around then I plan on posting the finished product. I'll probably post it on /diy/.

>>51568408
What are you making?

>>51568448
It's a raspberry pi guitar effects processor. I threw in a tube distortion circuit just because it sounded fun.

>>51568386
We should make our monthly EE thread
