Joule Thief
Building a Simple Joule Thief To build this, you'll need the following components: · Battery, rated at (or discharged to) ~ .5 - 1.5V · 1k ohm resistor · 2N2222 NPN transistor or similar · Coupled (2 separate windings, 4 connections) toroid inductor —2mH (millihenry) and 10mH tested, many others will work · LED
Joule Thief 101
8x more Output from a Simple Joule Thief Circuit. While developing this overunity circuit he was amazed to see an 8 fold or 8x improvement in the power output, which simply indicated an 8 times more output being produced by his circuit, compared to the input supply power. The results were distinctly evident on the oscilloscope screen which he.

The Joule Thief Circuit is a voltage booster circuit which converts a constant low voltage input into a periodic output of a higher voltage. This circuit can be most often seen lighting an LED with an almost dead AA battery. The peaks in voltage occur rapidly, causing the LED to flash at a very fast rate.
