For the typical joule thief, you'll need the following: battery in the 1-2V range. 1k resistor. NPN transistor (2N2222 used here) LED. ferrite coupled toroid inductor (2mH tested) Toroid Joule Thief. (Image Credit: Jeremy Cook) Wire your circuit as shown in the schematic and image above, and your LED should light up.
Is that a joule thief?
A joule thief is a minimalist self-oscillating voltage booster that is small, low-cost, and easy to build, typically used for driving small loads, such as driving an LED using a 1.5 volt battery. This circuit is also known by other names such as blocking oscillator, joule ringer, or vampire torch.

Joule thief efficiency evaluations « on: February 04, 2019, 05:00:29 pm » A decade ago (yes it has been that long) I became interested in joule thieves, and their outstanding capabilities to light up LED from very low voltages. Although the basic circuit works fine, it can be significantly improved.
Joule Thief 101
Hyper-Efficient Joule Thief. More efficient Joule Thief circuit based on a design by Tim Williams. It features somewhat less inductance than typical circuits, and gains efficiency by switching the transistor faster, approx. 50 MHz in practice. Best such circuit I've seen so far. It's a blocking oscillator.

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.

Joule Thief Efficiency Testing. Just seeing where I can push a 20-turn JT circuit and maintain a relatively stable output. Currently set to power a 3v LED with 0.9VDC. Usually joule thiefs can be made to work with as low as 200-300mV, as long as you use a germanium transistor. The only condition is that the Vcc must be enough to enable the.
Joule Thief Charging A Capacitor
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.
