A set of parts to build a multi-purpose pocket timer. The timer is fun to build and useful, with great repeatability and long time delays possible. The circuit provides an activity LED, a strident 'beep-beep-beep' warning when the time is up and a visual warning too.

The circuit uses a self-clocking binary counter that controls a number of relaxation oscillators that control each other.
