Self Playing Bayan Built Nearly 22 Years Ago

The year is 1988, where a Russian engineer [Vladimir Demin] has combined a Bayan, or button accordion, with several (we lost count at about 96) solenoids. If that alone doesn’t blow your mind the computer, also hand built by [Vladimir], controls the whole process leaving the operator to only work the bellows. Putting truth to the fact in Soviet Russia, accordion plays you. We wish we could find some more information about the instrument, but curse our inability to read Russian. Alas check after the break for a shorter version of the video in the link above.

  1. That is the ESSENCE of geek! seriously that is so awesome!
    bulding a computercontrolled accordion – check
    building your own computer to control the thingy – check
    appear on HaD 22 years later – CHECK! (at last!! )

    making absolutely everyone that feels just a little bit geeky today ashamed of their puny little *uinos – check indeed!

  2. Well, I do read russian (since I am russian) and I can say that there are unfortunately no build details at that link, so you didn’t miss a thing.
    But I can assist should you need any translation.
    And well, yeah, awesome work. So much reminds me of the goodies my grandfather used to make.

  3. He’s just a rack,a pneumatic cylinder and a proportional valve away from it playing itself.
    But it is way cool just as it is. BTW check out the O’scope in the background and the homebrew keyboard.
    Vintage coolness.

    1. That’s exactly what I was thinking. One can tell by the way he operates the bellows that he certainly knows what he is doing. Either that or he had time to figure it out between ’88 and ’97; but I doubt that. All of the work put into this is mind blowing; Vladimir is a genius.

  4. @ledtester: The video is definately from around 1997 (there’s PC with tray load CD ROM at the bottom left of the still image, even.) I highly doubt he’d have a video camera then, considering he had to build his own computer and keyboard in 1988. In the capitalist side of the world, you’d have this kind of thing hooked up to a consumer microcomputer at that time.

    Very impressive hack! Where’d he get the solenoids?

  5. @gyro_john
    I still use his homemade lab power supply he gave me, that can drive dc from 0 to 100V up to two amps at 4 separate channels, a stereo amp of his design (He used some unknown to me soviet military transistors. Even he doesn’t remember where he got the specs and the parts – works like a charm, although I never adjust it to the max – just blows the speakers I used. I also have a couple of smaller lab power supplies of his design.
    He also used to make a nice radio jammer, when
    He used to do lots of other analog circuitry, fix those old lamp-based tv sets… Hates the digital world =)
    Now when he’s over 80 he put the soldering iron away – a bit hard for him now.
    Btw. He’s the only one I know, who tests 220 and 380 volts ac with bare fingers (But never does it straight after dinner).

  6. First of all, he IS smiling. But he’s smiling in a humble manner. He also looks a little weary and tired — not surprising, considering the time the picture has obviously been taken (about 1997) and the economic situation in Russia at the time. The guy probably had to work real hard just to make the ends meet!

    Now, can you imagine how much trouble it may have been to find all the components for his creation in 1988 in USSR?

  7. More builds should make use of 8″ floppy drives. This is excessively cool! And are those keys on the computer made of plywood?

    (Why is “wierd al” in the tag list? He doesn’t look anything like him.)

  8. At first blush, the monitor looks like it could be a repurposed from an Agat (Apple ][ clone)… waste not, want not. But, I think that’s probably the only major Agat component. Otherwise, he’d have also been reusing the case, keyboard, and 5.25″ drive.

  9. @tom61: Says in the Youtube comments he wound the solenoids himself. With a coil winding machine this number shouldn’t take too long, but making all those formers and the plungers with the buttons on the end must have been dull work.

    Also, the computer is a Specialist. Soviet 8080 clone based and runs a CPM knock-off. Made from plans in a magazine article from the mid-80s apparently. tells me there was a commercial version called a Lik.

  10. Hard to refute the 1997 time stamp in the video, but I’m willing to take them fr there word that this was created a decade earlier on, and still uses the computer equipment shown. the decade that passes explains the acquisition of the newer computer equipment seen. My guess is that wierd Al is in the tag list because like weird Al (before Al gain some recognition). Vladimir ,wouldn’t come to mind if accordion pay was mentioned, both different in their own good way.

  11. since it seems the original hacker appears here ….
    could someone of the hackaday team have a interview with him.

    I would love to here about his CV and his hacking back in soviet times compared to today.
