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.
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…
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…
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 …
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.
Modified Fuji AA circuit running two 48″ 40 watt each floro tubes on single AA battery. Yes, this is still the same old AA battery used in all of my videos so far. More at Overunitydotcom on the Joule Thief topic.
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…
Here we see a Joule thief circuit operating from a supercap only. No battery included. The supercap is 2.3 volts and 10F. I charged it up for 10 seconds with an AA (old) battery. I plan on getting larger caps for future experiments. For more informatio…
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 …
