3D Printable Kit - The Joule Thief Flashlight!

Use your 3D printer with this electronics kit and make a flashlight that runs on dead batteries! A Joule Thief circuit is used to "steal" the last few joules of energy from mostly dead batteries. Once a battery drops below a minimum voltage, many devices cannot extract the remaining energy. There is no such thing as "free energy" but there are ways to prevent available energy from going to waste. The Joule Thief Flashlight Kit is available at the link below. Use our 3D models, available in STL and STP, or design your own! Comanufacturing is upon us!
