Arduino-controlled ball-and-bowl musical instrument

Arduino-controlled ball-and-bowl musical instrument

Kügli is an Arduino-controlled musical instrument by Stefanie Hess and Johannes Schmidt. The project consists of a bowl with a false bottom, packing an Arduino, XBee wireless module, and some speakers. The ball contains a Lilypad and another XBee.

The spacing and dynamic of a ball in a bowl influences sound. While holding the bowl in its hands the player can walk around and rock the bowl forth and back either smoothly or with fast movements. Two factors are relevant for the sound: the position of the Kügli in the ball and the rotation-speed of the Kügli. Both data streams are sent to Max/Msp via the serial port. The XBee component, accelerator and piezo-microphones are sensoring and passing the the movements.
