Make music with small DC motors
p2pnet news view Cool | Music:- Once upon a time I used to build radios.
Wonder if I’d have any luck with Gijs Gieskes’ Motor Keys instrument?
It,”produces some beautiful sounds,” says blog.makezine.com, going on:
“Reminiscent of the legendary Mellotron tape sampling keyboard, the project uses the popular ATMega168 chip and a modest part count.”
PCB image and source code are available on Gijs’ site, where he says »»»
This project can be used to make music with small dc electro motors, controled by a small keyboard.
This project originated from a old project of mine where i atempted to make a keyboard controll the speed of a walkman …
It only sort of worked, but over the years i have gotten a little better in electronics… so now i am able to make it work better.
Neat.

Wow that’s really creative. Thanks Jon for posting. That device has a lot of potential, especially for movie soundtracks, techno music, Indian music, etc..

Another interesting sound project a friend of mine is working on… apparently if you can modulate a spark jumping a gap to sound (music), it’ll produce a sound… says its called a “plasma speaking” because the air around the spark is so hot it turns into plasma….

^^ Very cool, Josh. Please ask your m8 to let me know when he’s ready to talk abut it
Cheers! Ands thanks …

@Josh, can he call it a Teslatron? He’s exceeding the dielectric breakdown of air, which requires a field of at least 3kV/mm, depending on the surface area of the electrodes and atmospheric pressure.

Duuuuuuude!
Way cool!
