Bathcratch is a music entertainment system that converts a bathtub into a DJ controller, allowing an average person in a bathtub to play scratching music. The system detects the squeaks made by rubbing the bathtub and associates them with several preset scratching phrases. In addition, capacitive touch sensors embedded in the tub allow the selection of scratching phrases and background rhythm tracks. Here, we provide a system overview and explain the design, user interface, music controller implementation of this system along with the feedback received for it during a public exhibition.
