This is another variation that’s a little cheaper to build and will give just a bit more light, but does not have charging. So, this is a Super Joule Ringer 2.0, but Tuned. I…
Prolly the closest I will get to an accurate Lasersaber replication of the Super Joule Ringer 2.0. A friend of mine wound this who doesn’t do electronics and I think that’s pretty cool. He…
A simple joule thief and LED powered directly from my earth battery.
made a mini joule thief with high frequency transformer from linear power supply
This is a video of 3 LEDs (2-265000 MCD and 1-26500 MCD 10 mm Ultra brights)running from a single AA battery. Each LED requires between 4 and 4.5 vdc and over 100 mA’s each to light. For more info, see overunitydotcom in the Joule thief topic. This is …
My Modified Fuji AA circuit running two tubes on an old AA battery. More info on Overunitydotcom in the Joule Thief Topic. Sorry about the quality, this was filmed using a $50 video cam, as were all of my other videos on here.
This was a very creative answer to the question I asked in my last video. The question was, how to pulse the AA battery to keep the supercaps charged enough to light the ultraviolet…
Quick video of a Joule Thief running 2 ultraviolet leds attached to plastic tubing coated on the inside with black light paint. (green) What I want to know is can we design a circuit…
A new Joule Thief circuit running on 3 supercaps. (2 are 2.3v 10F and 1 is 5.5v .47F) When the supebright led (28600 MCD) burns out after a one second charge to the caps, I can touch my finger lightly to the top of the transistor (2N3904) and the led l…
One of my toroid Joule Thief circuits using an N3904 transistor making unique sounds when placed near an am radio tuned near 7000 KHz. I find it interesting to hear it accelerate and increase in frequency. For more info go to Overunitydotcom. Thanks.
