The latest commission is for composer Chris Schlechte-Bond. It uses electrical interference of various DC motors to create noises and textures in the central pickup. 2 inputs are connected to some pulse width modulation boards to control the speeds of the motors and gives different pitches and textures. The other 4 inputs share a 9v battery source and so when played together they take some of the power away from the other motors, again creating a change of sound.
