Using little else than the parts inside an old GE boombox, Michael Colombo made TapeScape, a robot that front-mounts the jambox’s tape head and uses it to follow strips of cassette tapes on the ground.
The signal from the tape head is transmitted via FM radio to a receiver, which then records the glitchy sound of a robot dutifully following a strip of magnetized acetate. Future revisions will add remote-control. [Instructables via MAKE]
