Abstract
A dynamo powered amusement device is provided that has multiple amusement functions integrated into a housing. The amusement functions include two or more of a movement, a light emitting diode illumination, an auditory output and a video presentation. The electrical power source for the amusement functions is a manually powered dynamo. The direct current generated by a dynamo is provided to a printed circuit board in electrical communication with the amusement functions so as to provide power directly from the manually powered dynamo or, if a chargeable battery is present, to supply power from the chargeable battery. The amusement device provides enhanced performance relative to mechanical amusement devices while avoiding costs and environment problems associated with disposable battery containing amusement devices.
