Electro-piston flashlight using NO batteries or source of electricity.
thingiverse
Electro-piston flashlight requires no batteries or source of electricity. The electro-piston employs the principle that moving a magnet through a coil of wire induces an electrical current, making it a relatively straightforward project. It utilizes Neodinium magnets - I've achieved success with just one magnet, however. The wire comes from an old transformer and four diodes were sourced from a circuit board; using them prevents LED damage while increasing efficiency. A mechanism that turns only in one direction and a bevel gear transmission have also been incorporated. Check out the videos below.
