So now I have my Joule Thief powered by an old cell phone charger..
That's only 4 volts.. filling 2x 25 volt, 47000 uf caps in parallel.. Running the 100 watt mini inverter, which lights the 220 volt 7 watt LED..
The caps voltage is maintained at 11 volts...
Next step is to try and make it self looping...
Thank you very much for posting your design, i found your design of using joule thiefs back emf very easy to build and efficient, but joels version was necessary for us to understand it completely. i think using a hvhf generator with an av plug to charge caps is hard compared to using joule thiefs back emf. this is by far the easiest way to extract more amps with just 4v. thanks again.
