Piezo Box

The Piezo Box uses four piezo microphones attached to an Arduino Nano, via some 10k resistors. The Arduino is housed in a small Hammond enclosure, with the Piezos mounted to the surface with foam, to minimise vibrations across the sensors.

I have written a basic serial-to-midi conversion patch in Max which allows control over percussion instruments within a DAW, such as Ableton Live, or Logic.
