Thank you! I can't wait until I can afford my new 3,000 farad supercap and then the leds will all be lit for a very long time. On this single 10F cap, the 100 only lit for maybe 4 minutes. This is fun.

Very Well Done Bill.

Thank you! Yes, dig those leds out and lets make a lot of very cheap light from dead batteries. I myself have not done too well with the cfl. I may have to give it another go. I am sure my board will not run one for anywhere near your 12.5 hours, that is excellent! I will have to try some of your modifications to get there. Thank you again.

thanks ill have a look, i was having trouble staying focused while on the site, easy to get side tracked with all that info lying around.

hey, i've built a tesla radiant energy circuit, and i've gotten decent results with it. I'm currently using 2 .2 uF, 50v ceramic Caps, and 2 electrolytic 100uF, 50v caps. i have voltage, but i would like to get the wattage to run a small homemade DC engine. do you think using supercaps would help?

Yes, I believe it would. I am now using a 650 farad boost cap and those are available in 3,000 F and even higher. Only 2.7 volts but you can raise that with a simple circuit like the JT. Good luck with your experiments.

Wait, so this Fuji circuit is just like a flash circuit in a disposable camera?

Yes. It has been modified into a joule thief circuit.

Hey Bill! Awesome video.
2 Questions, if you have a second.
1) Is the Fugi board stepping up the voltage using some sort of inverter circuit?
2) How are you charging the super cap? Straight DC from a wall transformer? Variable power supply?
Anyhow, thanks again!

As listed in the video explanation area, I just hit the supercap with an AA battery for a few seconds to get the charge. Now, that is a 2.7 volt cap and it was obviously not completely charged using 1.5 volts and also for that short of time period. The Fuji board is basically a step-up transformer that has been modified into a JT circuit. and outputs about 400 volts with 1.5 volts input. Output would be higher if the cap was fully charged.
Thanks,
Bill
