A Joule Thief is a simple electronic circuit that can extract useful work out of a very feeble power source. It can be used to extend the life of batteries, gather power from a dimly lit solar cell or a tiny windmill. It's a fascinating device, and is very easy to build. You will learn about transistors, inductors, diodes, LEDs and more! This is a great introductory course for absolute beginners.
