Hand made triode

vac

[Claude Paillard] makes his own triodes (google translated) for short wave radios. The site doesn’t have a lot of details itself, but links to entire books on the history of radio tubes and manufacturing of them.  [Claude] takes us through the entire process of building a triode in a 17 minute long video. Even if you aren’t into them, this is fascinating. From the looks of it, several of us might only be a pump or two short of being able to cobble one together.

[thanks Dieter]

    Geeze, don’t you guys read your own site? I knew as soon as I saw the picture that this was the same hack as before. It’s a good one but still can’t you search your own site before posting?

    It is like watching someone tie a fly…. amazing patience and skill. Very relaxing.

    And the music is Gershwin. I think… specifically… The Man I Love.

    Soon homemade transistor!

  19. I’ve been doing transistors for a year or so now. It took about 2 years to find a process that can be done at home.

    Here is my setup I took to a conference and we made solar cells, single FETs and an inverter.

    This is an inverter:

    This is a quick talk I gave at metalab explaining the basics.

    Holy machine shop, Batman! No wonder he has so many jigs and rigs. I especially like the way he doesn’t wait for the mill to stop before reaching for the cutting tool. I though he was going to lose a finger there.

    P.S. Thanks for resurrecting this one, I probably wouldn’t have ever come across it otherwise.

    So this is, a repost. I kinda thought so, but still very cool. I don’t have the equipment to do this, but if I did I would definitely make my own.
    I didn’t even see the video this time around, but I know the song, and it’s stuck in my head..lol oh well at least it’s a soothing song.

  25. Caleb Kraft says:

    Hrm… it appears that it is a dupe. It happens. Send us more hacks to post!

  26. henk says:

    Homemade transistors?

    Now that’s hackworthy!

    Not saying that this isn’t tho.

  27. Tachikoma says:

    I was fairly impressed when I first saw this on hack a day a while back, and still is today.

    Re. home made transistors, you can just about make one yourself using a pair of safety pins and chunk of galena. Not exactly precision stuff, but it is possible. Hobbyists were doing similar stuff with crystal sets for nearly a century.
