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…
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 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…
Here’s an interesting effect I discovered just now. Don’t think your JTs are inactive just because the light goes out! Something may still be happening. Oscillations may start and stop without lighting the LED,…
My modified Fuji AA Joule Thief circuit lighting 300 LEDs! Each LED requires 3.5 volts to light. I am still using the old AA battery that you have seen in all of my other videos. For more information, go to Overunitydotcom in my Joule Thief topic. Thanks.
This joule thief works much better when the ferrite core is shorted with a wire – a magnet or a capacitor. I adjust the trim capacitor for the best resonance. The magnet must be…
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…
Just fooling around. Schematic for the Neon unit is at http://www.overunity.com/6123/jule-thief/dlattach/attach/128708/ Schematic for the Clothespin (AcmeFixer) unit is the top diagram at http://www.overunity.com/13884/acme-fixers-highly-efficient-joule-thief-help-needed/dlattach/attach/128423/ As always with JT type circuits, if it doesn’t work at…
This is the second part of the power measurement scope tests of the Lawrence Tseung Fleet Joule Thief circuit done by Stefan Hartmann, the admin of OverUnity.com . http://www.overunity.com/12686/is-joule-thief-circuit-gets-overunity/1065 Lawrence claimed the circuit to…
