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…
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 I show the simple DC Gate Threshold Voltage test for the IRFPG50 n-channel MOSFET. It is pretty easy to see that a voltage fluctuating around 4 volts on the gate is sufficient to…
The IRFPG50 is one tough transistor. Erratum: The duty cycle changed when I changed the range setting on the FG, and did not preserve the approx. 20 percent I had dialed in. Instead the…
ERRATUM: A couple of times I say “Drain” when I should have said “Source”. The actual intent is clear, I hope, since the wires are color coded. This video refutes the assertion by Rosemary…
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 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 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…
