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…
This is the ‘Automatic Solar Joule Thief’—-“Hewey”–boxed. The device is a simple Joule Thief LED/charger circuit with an automatic solar charger attached. It uses super capacitors instead of batteries to store the energy. “Hewey”…
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…
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 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 new and improved earth battery running 4 ultra bright 10mm 28000 MCD LEDs. I am using a standard Joule Thief circuit wound (bifilar) on a ferrite toroid this time. An N3904…
This shows a battery that uses calcium cloride to draw moisture out of the air and help run a copper and magnesium battery. I also show a simple Joule Thief circuit that uses the…
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…
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 …
