Abstract
A gyroscopic wrist exerciser has a transparent plastic housing and a gyroscopic rotor mounted on an axle rotating on a primary axis of rotation about the axle. Ends of the axle are extended into a circumferential housing groove disposed on an inside surface of the transparent plastic housing to rotate in a secondary axis of rotation about the circumferential groove to provide precession of the gyroscopic rotor. A permanent magnet cooperating with a coil produces an electric current proportional to the speed of the rotor. A microcontroller connected to and powered by the coil has three separate outputs, namely a first output, a second output and a third output which receive degrees of voltage depending upon an input voltage from the coil. A first LED chip, a second LED chip, and a third LED chip are connected to the microcontroller at the three outputs.
