Abstract
A lighting system for toys such as floating disc toys wherein a plurality of point light sources are spaced apart in the plane of movement and are energized intermittently by a battery through a circuit which utilizes a single multi-NAND gate chip and finger resistance for switching.
Claims1
A lighted floating disc toy comprising:
- a floating disc body;
- a plurality of lamps mounted at spaced points on said body;
- a source of electrical energy;
- energizing means for energizing said lamps from said source intermittently;
- said energizing means comprising a multi-vibrator connected between said source and said lamps;
- said multivibrator comprising a capacitor and a resistor and first and second NAND gates, each having at least two inputs, the output of the first gate being connected to a first input of the second gate through said capacitor, and a second input of the second gate being connected through said resistor to the output of said second gate and the inputs of the first gate;
- said multivibrator further comprising a path through a resistor for discharging said capacitor;
- and
- means in the form of at least first, second and third separate exposed terminals, and a flip-flop, for rendering said energizing means effective and ineffective, selectively, in response to simultaneous touching of said first terminal and one of said second and third terminals, respectively.
