Electro-piston flashlight using NO batteries or source of electricity.

I'm building an electro-piston flashlight that uses no batteries or electricity source. Can you believe it? The electro-piston operates on a fundamental principle: when you move a magnet through a coil of wire, it generates an electrical current. This project is surprisingly straightforward and only requires a few Neodymium magnets (you can even get away with just one). I salvaged the wire from an old transformer and used four diodes from a circuit board to ensure efficient operation - using just one will prevent your LED from burning out, while four will make it even more efficient. I've also designed a mechanism that turns only one way and includes a bevel gear transmission for added functionality. You can check out my electro-piston videos below to see the project in action.

The Electro-Piston V2.0 is now available for download on Thingiverse. To see more of my projects and stay up-to-date with my latest work, be sure to subscribe to my YouTube channel.
