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…
Full spec, details and solution below. A variant of the Cool Joule circuit by TinManPower. See his channel for the original circuit and ongoing experiments. See Lidmotor’s channel for the circuit diagram and his…
Here I show how easy and quick it is to make a simple printed circuit board for your Joule Thief. Copper clad board, the resist pen, and Ferric Chloride etching solution are available at…
I’m putting this in the Joule Thief category for now. Tinman’s circuit shows some very interesting behaviour. These white LEDs are absolutely the brightest I have ever seen, without blowing. They hurt my eyes…
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 example of wireless electricity experiments (more within my YouTube channel). Here we have a dollar store type of flashing lights circuit, that has some interesting traits. The flash type can be set with…
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….
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…
