This latest, low-cost starter project is sure to be a turn-on. Just a gentle tap or clap will trigger it into life.

This simple nightlight starter project is switched on simply by tapping on the case, or gently clapping one's hands close to the unit. The low power bulb then switches on for approximately five minutes, but it can be switched off at any time by operating a Reset button on the top of the case.

The unit was primarily designed with children in mind, but it could obviously be a useful gadget for adults as well, particularly disabled people. It is battery powered and is therefore safe for use by small children. The simple circuit and lack of mains power also makes this project suitable for construction by complete beginners.
