Touch Start Stepper Motor circuit
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…

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…
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…
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…
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…
Rosemary Ainslie demonstrated her NERD circuit on Saturday, June 29, 2013 and streamed it live on YouTube from Cape Town, South Africa, to the world. This is one of several videos I’ll be posting…
