Joule Thief

[gadgetmall]

 @all . this is the final Mod to Very Low Power Joule Thief . I have Named it Fusionchip/Jeanna Low Power JT  Or FJLP Because it used some of her Work !! Combined it produces a Usable Output at Very Low Input Power .Let me Recap :  It Beats all Know Public Domain Joule Thief Experimenter Circuits that use a transistor and Claimed to be The Lowest Input power to light 4 White Leds @ .202ma each. So a Normal Jt will extract from a battery 10-15ma while this one extracts 0.20 - 1 ma .. adjustable .. You need two Pots and two 680-Pf . I tried a lot of combinations replacing one pot with a 20 k resistor and it did not reduce the current . I tried different coil configurations for primary and secondary and this is the best combination i came up with . It might be improved So go for it  . Also i wound the Coil in an Unusual way and if you want to build it i will give you the SECRET I came up with  Can you Guess  We will see .Duplicate the Circuit and post the picture and Pm me For the  Secret . Hint : I wound primary With One wire .Heres a Quiz for Ya . A cowboy rode into town one weekend  on friday and stayed at the Inn for three days and then left on friday . How did he do it ?
