Abstract
There is disclosed an illuminated flying saucer toy is which incandescent lamps are pulsed on and off by an astable multivibrator circuit. The circuit is arranged to pulse at a relatively slow rate when the toy is at rest and at a relatively increased rate when the toy spins at a rate above a predetermined minimum. The increased flash rate is provided through a normally open switch that closes upon rotation of the toy to insert additional resistance into the circuit in parallel with existing resistance thereby to reduce the resistance by which flash interval is determined.
