Simple 2 LED flasher kit

This simple kit allows you to create a 2 LED alternating flasher.

The circuit is based on a two transistor oscillator, one of the oldest electronic circuit designs. There are no ICs and it is a very simple kit to build.

The circuit is designed to run from an operating voltage of 3 to 9V, so ideal for battery powered applications. We sometimes have a version of this kit that comes with a battery holder, but can't guarantee you will get the battery holder version. The kit comes with either white, blue or red LEDs, but any 20mA LEDs could be used.

Uses include toys, attention getting flashers, warning flashers etc.

Note: kit style and PCB may vary, but basic operation will be the same.
