HANDY TIMER v3

Click to enlarge

This is a new version of this timer which makes the sound a little louder.

The timer works in intervals of 30 seconds. Every push of the button advances 30 seconds and an LED. Pause and press to cancel.

There are sound warnings every 30 seconds as the timer counts down, then plays a brief tune when timing has finished.

Circuit goes to sleep when not in use, drawing about 5uA. No switch is needed and the battery lasts for months.

The battery is a commonlyused 3v button cell that fits in a holder on the PCB meaning there are no wires needed at all!.

Power Supply: 3v (1x 2032 button cell, sold separately)

The kit contains PCB, all components including battery holder.

Kits sold as single, 10x pack and 50x pack.
