This is a continuation of my work on the MiniFuji circuit and the Light Of America LED lights. Each LOA bulb (designed to operate on 120 volts grid power) has 27 chip LEDs and here I am lighting two of them from one MiniFuji circuit. I am working on a smaller version of this circuit and I will use that in the second light. There is a lot of light from these bulbs on a single AA battery. For more info go to Overunity.com in the Joule Thief topic area. Thanks for watching.

  • Thank You Very Much Bill. I know what current is. Wheb nine I got glued to the electict stovefffor about seven to 10 seconds. I was the ground for the stove via the refrigerator. So about 35 to 45 Amps coursing though one arm out the other into the fridge. My grand mother tried to pull me off but was sent flying 10 mfeet away. Her second attempt succeeded and I took the oven door with me. I slept for one full day. It was not known that one should not sleep afer such an experience..

    Thx

    Ouch. That had to hurt. I too have been zapped many times....several times with 440 amp 3 phase.....not fun. I only posted that warning because I didn't want someone that did not know to get hurt. sounds like you have been around the block already.

  • How did you modify the fuji circuit? I have two fuji cameras and took apart one but have not altered it. Frankly I don't want to burn them out.

    It would be appreciated.

    Edward, all of the schematics and instructions on how to do this circuit, as well as many others, are over at Overunitydotcom. (Put a period where the dot is) It is easy to do but, be careful this is high voltage and it does bite...trust me on this. Discharge that large cap in a safe, grounded manner even if you never turned on the camera...they still carry a huge punch and can burn right through your skin. Josepinodotcom has some good photos but we improved it.

  • Hi Bill,

    I like the clear plastic holders where the lights are mounted, everything is made so if something fails it can be pulled apart, repaired and popped back together nice and easy.

    You put some thought into and it shows, well done, this twin is very nice indeed.

  • @Pirate88179 Thank you for the reply bill.regards stef

  • @harpbloke

    I agree, I think it looks like that too, ha ha. You know, I checked that before disconnecting the second light and, to my eyes anyway, the 2 appear to be as bright as just a single light. I did not check but I am sure the amp draw is higher. Thank for your comments.

  • @stefb2005

    Thanks. I think the bulbs were about $10 US each. I do not know what is inside them as I could not get one apart...so I just hooked it up directly to the Edison base and it works. I suspect there must be some circuitry inside similar to a CFL, either that or they have it figured that it takes 120 volts to run those 27 leds. All the schematics are over at overunitydotcom. (Replace "dot" with a "." I really should include those in my videos though, you are correct.
