Blinker is available as a soldering kit or pre-assembled.

The Blinker circuit builds a free-running multivibrator that combines PNP transistor switching with a Capacitor-Resistor (CR) discharge circuit to create a two blinking lights whose blink rate can be changed by changing the capacitor size. Students can clearly see how capacitors discharge at different rates or can use an oscilloscope to track the discharge rates directly.

Each kit comes with a Blinker PCB board, battery holder with battery and on/off switch, 2 electrolytic capacitors, 2 PNP transistors, 4 resistors and 2 LEDs.
