35 joule thief circuit diagram

1918 (Venn's diagram is from 1904), named for English logician John Venn (1834-1923) of Cambridge, who explained them in the book "Symbolic Logic" (1881). Old English þeof "thief, robber," from Proto-Germanic *theuba- (source also of Old Frisian thiaf, Old Saxon thiof, Middle Dutch and Dutch dief, Old High German diob, German dieb, Old Norse þiofr, Gothic þiufs), a word of uncertain origin. A thief takes other people's property without their knowledge ; a robber takes it openly, whether or not resistance is offered : in a looser sense, thief is often applied to one who takes a small amount, and robber to one who takes a large amount. [Century Dictionary, 1895]

As can be seen in the diagram, the circuit involves only a single transistor T1, a couple of resistors R1, R2 and the inductor L1 for the main operation. When ... I'm on a wireless power transfer project and I "accidentally" made this circuit. At first, I needed a oscillator that makes full wave ac and tried MOSFET joule thief and realized that it's one of the blocking oscillators that makes half wave ac after trying to light an LED connected with a coil and found out that the LED turns on only at the one side of receiving coil. So I thought "what if i put two MOSFETs with two connectors(gate and drain) changed except source which is connected with ground... late 14c., "a circumference; a periphery, a line going around (an area), whether circular or not; a circular or circuitous course," from Old French circuit (14c.)

This is my first try at making the circuit. I burned out all the LEDs I had laying around. My main goal is making one that the output can be measured. I don't really care about lighting an LED. Here are the 2 toroids I made and tried, maybe the wrong toroid cores? http://i.imgur.com/aKtu8mK.jpg I have some NP 2222a transistors and a couple other ones I have also tried.

protection - Regulated Joule Thief: why it works ...

I saw [this video](https://youtu.be/xUQYMfPac0g) on wireless power transmission, which seems similar to a [Joule thief oscillator](https://en.wikipedia.org/wiki/Joule_thief) (working without any capacitors). However in contrast here the two primary coils are wound up in the same direction. How does the oscillation work here (without any capacitor), does it oscillate even without the second part of the transformator(with the LED)? From what I understand the circuit diagram looks somewhat like [t...

Fuji Circuit Joule Thief LED Light / 1 - YouTube

I'm working on a small crank-able light using a DC motor,capacitors, and LEDs with a joule thief to drain the capacitors completely when the voltage in them drops too low for the LEDs. However I want the power from the capacitors to be able to go directly to the LEDs before the capacitors drop to low voltage then switch to going through the joule thief when they hit the low voltage point to get the most efficiency. Any suggestions on how I can achieve this? I am not the best with electrical ...
