Joule Thief: Gang of Thieves Part 1: LaserSaber’s Ghost Light Circuit as Power Supply
I call it the “ghost light” because of the way the LED glows dimly for a long time with the battery disconnected and the earth ground in the circuit and fingers touching. But my present modification is more like scratchrobo’s, since I took out the bridge and the “ghost light” effect no longer works. I still can’t find HV either, but I haven’t tried more than 5 volts on the input yet. Here I show the GhostLight powering the JTBasic, quite effectively, if rather noisily.
