# Joule Thief This is a simple Joule Thief playground of sorts. There are a lot of places to attach a battery and attach an LED to this. Its a very simple circuit, but my problem was that without a good place to attach things, it falls apart on me. See here for good example. The hardest part is really getting the wires correctly wound and placed from the torrid. https://rimstar.org/sdenergy/joule_thief.htm ## Description ( Thanks AI) The Joule Thief is a cleverly designed, compact electronic circuit that enables the extraction of energy from nearly depleted batteries, effectively "stealing" the remaining joules of power. This circuit operates by using a simple but ingenious configuration consisting of a transistor, a resistor, and a toroidal transformer. The primary function of the Joule Thief is to boost the voltage of low batteries, typically below the standard operating level of many devices, to a level where they can still be useful. This is achieved through a process called voltage boosting, facilitated by the transformer and controlled by the transistor's switching action. As a result, the Joule Thief allows batteries that would otherwise be considered dead to continue powering devices such as LED lights, thus extending battery life and enhancing energy efficiency in a practical and cost-effective manner.
