Kügli
Rock the bowl
(Stefanie Hess, Johannes Schmidt, 2009-07-20) 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. This energy is moving the ball – Kügli – and uses the energy to spin. 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.
Our idea
The setup on the breadboard
On the ground of the metal-bowl we put a paper surface, on which we installed the arduino-board + microfones
the ball with accelerator,xBee and lilypad-board
rock the ball - result
