ABSTRACT:
There are disclosed herein various forms of ornamental devices such as jewelry and the like, including a plurality of light sources, the light sources being illuminated in a random or substantially random fashion. An exemplary belt buckle is illustrated, including a circle of light sources of two different colors. Several suitable electronic circuits for driving the sources are disclosed, and any one of the circuits can be physically attached to or form an integral part of the ornamental device. Each circuit includes one or more oscillators along with logic elements, such as logic gates and/or registers, for providing electrical signals for turning on and turning off the light sources. Typically, the light sources are light emitting diodes. In one particularly useful form of circuit disclosed herein, the light sources are turned on and off one at a time in a random fashion and the frequency of the on/off cycle varies.
