Joule Thief Variant: Instructions, Detail
NOTE: I have the transistor backwards in this video! For some reason it still works with this particular transistor, but it won’t work backwards with 2n2222a. You must connect Cathode of LED to Emitter…

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…
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 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…
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 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.
lasersaber’s oscillator; base of transistor triggered from negative side of circuit; very good finding, laser, thank you for sharing…
I finally got my Slayer Exciter to run on a Mosfet transistor. The Mosfet is a Radio Shack IRF510 which isn’t supposed to work, but I got things just right and the magic light…
Tinsel Koala (TK) at overunity.com tossed out an idea to have a JT circuit using a battery as the core. I thought this to be a brilliant idea. It probably still is…however, I have…
