1.2V simple ‘555 A-Like’ circuit
Low voltage, low current possible solution for those without 555 timers in the spares box. The basic circuit is much like a Joule Thief, similar toroids, windings and transistor can be used. The Collector…
Input Current measurement test into the 300 Watts inverter with the ALUM electrolyte car battery
http://www.overunity.com/13731/how-to-convert-a-lead-acid-car-battery-to-an-alum-battery-part-1-to-7/ In this video I am showing additionally the current input into the inverter from the battery while also showing the voltage on the battery. I am also showing the idle input current when…
First tests with a 300 Watts inverter on the ALUM electrolyte car battery
http://www.overunity.com/13731/how-to-convert-a-lead-acid-car-battery-to-an-alum-battery-part-1-to-7/ In this video I am showing a load test on the modified car battery with a 300 Watts inverter driving a 28 Watts halogen bulb and a 100 Watts incandescent bulb on the…
My 4evr Light
This is a glimpse at my “4evr Light”. It is a one led indoor light that runs all the time, doesn’t stop, and uses tiny polyacene capacitors instead of batteries. It runs on ambient…
Chilliqueen high voltage circuit using camera parts.ASF
This is a replication of Chiilqueen’s high voltage inverter circuit that uses electrical component parts removed from a disposable flash camera. The project required careful removal of certain small parts from the printed circuit…
Joule Thief Pirate Light
This is a simple light fixture made using a modified Fuji circuit Joule Thief and a disposable plastic food container. It lights up an 18″ tube pretty well and this is very easy to…
Running a pulse motor on infrared light.ASF
This shows my little light powered self-start pulse motor running on an infrared LED light source. The camera that I am using is able to show the light even though my eyes cannot detect…
Joule Thief LED Flashlight (Free Light)
This is a Joule Thief Flashlight. I simply modified a cheap 5 super bright LED flashlight that ran on 3 AA batteries by gutting it and using a simple Joule thief circuit which now…
The "Cool Joule" LED circuit
This is a variant of TinMan’s “Cool Joule” circuit. It is an LED light circuit that charges at the same time that the light is being powered. The circuit is simlar to a “Joule…
