The WIND-UP TORCH provides light, using 3 super bright LEDs. The torch has a 3 stage gearbox connected to a small DC generator, which is turned by hand.
The power provided by this generator is used to charge a small Lithium ion battery. The battery provides power for illumination, and a switch allows selection of low level lighting (a single LED) or a bright light (3 LEDs).
When discharged, the battery is recharged by turning the handle for approximately one minute.
The components provided for the WIND-UP TORCH include a Printed Circuit Board, the circuitry components, the generator, gears and other components to construct the gearbox. To complete the project, the student is required to design and make the torch’s housing and handle.
