Abstract
A spotlight system including a spotlight continuously rotatable about a spotlight pan axis and tiltable about a spotlight tilt axis. The system includes a spotlight controller including a housing continuously rotatable about a controller pan axis. The housing has a circumferential lip that engages with a fixed based and a hub engaged with a handle. The handle rotates about a controller tilt axis perpendicular to the controller pan axis. A controller board is electrically connected to a slip ring that penetrates the base, with a pan input sensor, a tilt input sensor, and a microprocessor. The pan input sensor measures the position of the housing relative to the base, the tilt input sensor measures the position of the handle relative to the housing, and the microcontroller interprets the positions and generates control signals corresponding to the direction of a spotlight.
