Abstract
A light display is mounted on the spokes of a rotating bicycle wheel. The display includes a plurality of arrays of lights, each array attached to one of the spokes. A sensor on the wheel, actuated by a magnet mounted on the frame, senses the angular velocity of the rotating wheel with respect to the bicycle frame. A microprocessor, mounted on the wheel and connected to the sensor, and individually connected to each of the plurality of arrays of lights by a cable, includes a memory which stores a plurality of display patterns. The microprocessor modulates the plurality of arrays of light according to a selected one of the plurality of display patterns and the sensed angular velocity of the rotating wheel to form an image using persistence of vision of a viewer.
