www.overunity.com Visit at Per-Johan in Abod Öglunda Sweden to work on the Prof. Jones circuit.. I just stopped by Per-Johan´s place on my vaccation trip to say hello, as I was near him and…
This is a Stepper motor circuit by sMartcreations2010 that can be started by touching a wire. It is a simple two transistor circuit. I drew the circuit diagram wrong and there are two parts…
Developing and testing the Minnie LiPo Low Voltage Cutoff circuit. Schematic at the end 5:14. NOTE: The S Weir mods make the circuit work better. Use a 2n7000 mini-mosfet instead of the BC337 and…
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…
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…
This is a tiny Slayer Exciter mounted on a circuit board. I show it here lighting up a 4 watt fluorescent tube as well as a neon bulb and three LEDs. The circuit is…
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…
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…
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…
Just for fun I put together the new Ainslie multiplemosfet circuit, using 2n7000 mini-mosfets. It oscillates just fine, batteries in or out….. because it’s running on power supplied by the function generator. It’s insensitive…
