Electric OU: Grey Box Q-17 Circuit Heat Output vs DC Input Run 1
This is the first experimental run of the test series, more or less a shakedown run. I am testing the Lost Grey Box circuit published by Rosemary Ainslie in a set of photos last…
24 hours runtime later – carbonfiber alufoil cells raised voltage on LED
http://www.overunity.com/13282/carbonfiber-alufoil-selfmade-diy-battery-with-naco3-or-ashwater-electrolyte Hi, I have now let it run over night contineously and now after about 24 Hours runtime the voltage has risen to 2.58 Volts again and the LED chip is brighter again. Regards,…
Joule Thief Surplus Flash Circuit Lights
These are two JT lights I made utilizing a no name surplus flash circuit I obtained from Electronics Goldmine for $.69 each (US). These boards were designed for an AA battery and appear to…
