Mmmmmm... knobs...

OK, seriously.

I have for sale, a PCB with 8 rotary controllers, another PCB with 9 faders, and a third PCB with 8 drum pads and their rubber buttons that go with them, available to anyone who wants to use them for a MIDI or USB controller project. All you need is an Arduino, a soldering iron, and a multimeter, in order to build your own bad-ass controller with knobs.

All three boards were salvaged from the M-Audio Axiom 49. AFAICT they all still work (it was the motherboard that died on the Axiom). I can scan pictures of them if you really like.

Anyone interested, make me an offer, either for individual boards or for the whole batch. I need the money. I'll find a way to ship anywhere in the world; these things don't weigh much.
