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…
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…
Saw & Vacuum Auto Switch W/Time Delay Off. (LOAD SENSING) Built With Junk. Schematic / Explanation RWGresearch.com In this video i will show you my how i created a a load sensing switch for…
Combining present circuit ideas with those of the recent video by PMMG4HYBRID, this video demonstrates a peculiar phenomenon…that of a li-ion cell charging back up after moderate usage. Whether cell chemistry, radiant conditioning or…
This is the basic circuit that started out as the LaserSaber Crossover circuit, morphed into the Earth-ground-effect-coupled Ghost Light, and now with gadgetmall’s mods is the selfcharger, or in my case, the runner-on-zero voltage…
An Alum water cell was due for a charge, reading 0.7V and 4mA. I decided to try using an Electrifly battery charger, to see whether it would work – not recommended, unless you have…
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…
An experiment that worked out quite well, running a wireless electricity circuit from water in an unconventional way. Features ———— The transmitting bifilar pancake coil has 1 wire disconnected – leaving only 3 used…
This is a 60 watt equiv. LED bulb that uses 9.5 watts when driven by the mains. It is rated at 800 lumens and is the best LED bulb I have tested to date….
