Joule Thief: Making a Quick and Dirty PCB Joule Thief
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 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…
I am replicating a test I saw on the net where folks listened to their Joule thief circuits using an AM radio. Yes, this is still the same old AA battery as I used in all of my previous tests. Here I test a regular Joule Thief toroid circuit and the Fu…
This is a 2.3 volt 10F supercap which replaces my AA battery in the Joule Thief circuit. I charged this cap with a single AA battery for about 10 seconds prior to filming. I did the same thing about a week ago and the LED stayed illuminated for about 2…
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 my earth battery running a 48″ (40 watt) florescent tube. It is not at full brightness but it is lit and lit pretty well. It is much brighter than it appears on…
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 nothing more than a coil of plastic tubing filled with water. I added a 265000 MCD LED on each end of the tube. I am powering this with one of my Joule thief toroid circuits. Although it does light well on a single AA battery, I decided just to…
This Joule Thief work at a very very low input voltage from 0.125 to 0.35 volts and the output voltage is 2.7 volts, to the LED. An ordinary Joule Thief work down to 0.6…
This joule thief works much better when the ferrite core is shorted with a wire – a magnet or a capacitor. I adjust the trim capacitor for the best resonance. The magnet must be…
