This is a serious musical instrument. It rotates everyday things, scans their surfaces, and transforms them into audible frequencies. The instrument was built from aluminum tubes, white POM, black acrylic glass, a high precision distance measuring laser ( with the kind support of Micro-Epsilon ), a stepper motor, and a few bits and bobs. A custom programmed translator and controller module, written in processing, transforms the measured distance values into audible frequencies, notes, and scales. It also precisely controlls the stepper-motor’s speed to sync with other instruments and musicians! Created by Dennis Paul More info about this one here
