Joule Thief LED Flashlight (Free Light)
This is a Joule Thief Flashlight. I simply modified a cheap 5 super bright LED flashlight that ran on 3 AA batteries by gutting it and using a simple Joule thief circuit which now…

This is a simple light fixture made using a modified Fuji circuit Joule Thief and a disposable plastic food container. It lights up an 18″ tube pretty well and this is very easy to…
Here I show how easy and quick it is to make a simple printed circuit board for your Joule Thief. Copper clad board, the resist pen, and Ferric Chloride etching solution are available at…
This is the first part of the power measurement scope tests of the Lawrence Tseung Fleet Joule Thief circuit done by Stefan Hartmann, the admin of OverUnity.com . http://www.overunity.com/12686/is-joule-thief-circuit-gets-overunity/1065 Lawrence claimed the circuit to…

This is my replication of Lidmotor’s Jeanna Light using Jeanna’s large toroid Joule thief design and Lidmotor’s circuit. This circuit puts out between 1200-2000 volts! I do not have an exact measurement yet. (I…
This is my version of the Basic Wireless JT. I was inspired to build the LED bank by Sohei Thoth, and I’ve been considering powering a JT with my wireless power system. So here’s…
A Joule Thief night light made from an empty plastic water bottle filled with glass spheres and plain water. Powered by a single AA battery. (This is the same AA battery used in all of my video experiments to date) This is actually a lot brighter than …
Full spec, details and solution below. A variant of the Cool Joule circuit by TinManPower. See his channel for the original circuit and ongoing experiments. See Lidmotor’s channel for the circuit diagram and his…
Here we are illuminating a 40 watt tube from a single AA battery. This is a modified version of Josepino’s disposable camera circuit. I have used this same circuit to light 2 of these 48″ tubes end to end. I have also illuminated 400 leds with this sam…
