In this video I show the Joule Ringer output run back into the source capacitor through an AV plug. I also show a seperate Joule Thief circuit with a three transistor Darlington arrangement that…
This is a modified CFL circuit using only one Darington transistor as the switching device. It takes the place of the 2 transistors that I used in my last video. The system runs on…
Another application of the simple, sensor driven voltmeter. The 2n3055 bipolar power transistor is used along with the Arduino’s pwm output to function as a sensor-controlled light dimmer. The photovoltaic cell is still useful…
This is Slayer’s Exciter circuit using a PNP instead of an NPN transistor. The circuit is basically run backwards. I show the circuit illuminating two fluorescent tubes and transmitting energy wirlessly.
The JT Basic circuit is used with a 1n914 (or 1n4148) diode in place of the Base Resistor. Cathode towards transistor Base. The circuit is the Basic 2n2222 or 2n3904 JT, available everywhere. the…
This is a replication of the “Daftman’s” one AA battery LED light circuit. It was posted at the “Teep” forum and shows another way besides the ‘Joule Thief ‘ circuit to boost voltage high…
Here the new Steorn motor v3, a more closer replication by Jean-Louis Naudin of the original demo rig version presented on Dec 15, 2009 in Dublin by Steorn… This model is used as a…
This shows how wickedly lopsided the “Tiny Orbo Replication 4” is. It’s hard to believe it spun at over 17000 rpm from ~ 10 mW (not including joule heating). If we include joule heating, then it was ~ 180 mW. By my calculations the heat produced by thi…
