Joule thief from http://joulethief.com/kit.php?
The joule thief from this website was the first working one I built, mainly because I'd favoured one without a tapped inductor. Anyway, I pulled it out a couple of days ago, and started poking around with it. I noticed that if I put a 10uf (or maybe it was 1uf or 100uf, sorry, I don't remember) capacitor in parallel with the 0.001uf capacitor, the LED would start to flash. this would not happen with any other value however. Why does this happen?P.S: I've heard that this joule thief is poorly designed. Is this true?http://talkingelectronics.com/projects/LEDTorchCircuits/LEDTorchCircuits-P1.html
