This is my new and improved earth battery running 4 ultra bright 10mm 28000 MCD LEDs. I am using a standard Joule Thief circuit wound (bifilar) on a ferrite toroid this time. An N3904…
A new Joule Thief circuit running on 3 supercaps. (2 are 2.3v 10F and 1 is 5.5v .47F) When the supebright led (28600 MCD) burns out after a one second charge to the caps, I can touch my finger lightly to the top of the transistor (2N3904) and the led l…
