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 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 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…
My modified Fuji camera AA circuit lighting a string of 100 clear LEDs using only one wire from the circuit. All I have to do is hold my hand near the battery and it lights. When I bring my other hand close to the LED string, they get brighter. This is…
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 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…
I took pieces of different circuits and joined them to make a 555 timer “Pulsed Invered Joule Thief”. It uses Slayer007’s 2″ toroid coil, Kubikop’s 555 timer pulsed joule thief circuit, and my inverting…
