The "Flashing Heart" is a very simple circuit based on the famous 555 timer. Build and have fun!
The prototype consists of 2 boards: The first board contains the 555 timer and the second one contains the LEDs. The heart "beats" at an adjustable constant rate. The circuit can be powered from a simple power supply unit, a DC power-pack unit or from a car battery. Besides flashing, the heart can be easily upgrated to also produce some realistic "tick" sound. Sound can be added by connecting a relay, a buzzer or a simple piezoelectric speaker at the main-board's outs.
