Earth Battery Joule Thief LEDs Experiments
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 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…
Avast!!!! Lighting 200 LEDs on a single AA battery using the modified Fuji Joule Thief circuit. The battery, which is old and nearly dead, will not even light 1 single led by itself. A new AA battery will not light one of these leds alone. More to come…
This is my earth battery and modified Fuji joule thief circuit lighting 400 leds. Please see my other videos for explanations on the circuits and for more information on the earth battery. Join us…
This is just a quick video of my new earth battery set-up. I am using the same 2 carbon rods but this time, on the minus side, I am using a large block of…
This is another replication of the Lidmotor/Jeanna Joule Thief circuit. I am using two Lights Of America 4 watt (25 watt equivalent) LED bulbs being driven by a hand-wound 3.375″ diameter Lidmotor/Jeanna circuit. (TIP…
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 …
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…
Joule Thief Test circuit lighting 2 LEDs. One LED is 28500 MCD and the other is 265000 MCD. Each LED requires about 4.5 vdc each to light. Circuit is powered by single AA battery. More can be read about these experiments on Overunitydotcom in the Joule…
