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…
Just a quick video of my new Luxo Lamp using my modified 60W Cree LED bulb powered from my Joule Thief Power Box. (AA battery) These Luxo lamps are very versatile and can be…
This is a replication of Jonnydavro’s “Reverse Joule Thief”. It is an LED oscillator that will run at under 100 millivolts. I show it here with a microwave oven transformer but the circuit will…
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 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…
This is a variant of TinMan’s “Cool Joule” circuit. It is an LED light circuit that charges at the same time that the light is being powered. The circuit is simlar to a “Joule…
This is my earth battery powering a joule thief circuit and running 7 ultra bright, 10mm, 28500 MCD LEDs. I misspoke myself in the last video, these are 28500 MCD not 28000 like I…
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…
