Modeled after the design of the rotating fluorescents used in Rafael Lozano-Hemmer's piece, "Homographies", I built this rotating light assembly for artist, Gretchen Skogerson. It is controllable via a custom-built web interface. An Arduino microcontroller receives messages from an IP connection, and sends signals to a motor controller board. It uses a stepper motor, chain drive and a mercury cored rotating electrical connector. ---- More info.
