Abstract

A strobascopic light source and a rotatable toy to create exciting optical illusions as to the toy'"'"''"'"'s rotational or lateral motion. Light emitting diodes placed on the periphery of a resilient aerodynamic disc toy which is thrown from one player to another cooperate with a multivibrator type electronic drive circuit, to create an unusual strobascopic effect.

Claims

1. A toy comprising a disc having a downturned peripheral flange and adapted to be propelled through the air in free flight and concurrently rotated during at least a portion of said flight at a predetermined rate, light means in diametrically opposed portions of said flange, control circuit means mounted on said Disc and connected to said light means, said circuit means being operable to turn said light means off and on at a frequency which is approximately a whole number multiple of said rate to thereby produce a strobascopic effect for a viewer of said disc during free flight thereof, said control circuit means including means for generating light pulses spaced apart at time intervals, and means determining said time intervals, said control circuit means providing for a voltage-time relationship for each diode in which the voltage falls off exponentially from a peak so that the light from each diode appears to go out quickly concurrently with rotation of the light during free flight of the disc to thereby give the impression of a comet-type light pattern.
