Yesterday’s silent windchimes, hooked up to a computer via usb midi. The chimes are made of conductive fabric, suspended by conductive thread from a microcontroller which sends midi notes whenever two chimes touch.

A DC motor makes the string whirl around. A second DC motor acts as a hub, and is connected directly to an amplifier.

No more mic and amp – the Stroh clamp is all acoustic! Still sounds like screaming goats, though.

The acoustic amplifier is made from a round mint tin, an old bike horn, and a laser-cut bridge borrowed from the 8-bit violin.

The electric clamp was Day 19.

I took the teensy screamer (day 12) and hooked it up to a computer to get a slightly less horrible sound.
