A self-oscillating voltage booster. Can use nearly all the energy in a cell, even when other circuits consider the cell dead. The name suggests that the circuit is stealing energy or "Joules".
The circuit is self-oscillating (blocking oscillator) forming an unregulated V booster. No energy is created by the circuit. Output V is increased at the expense of higher current draw on the input. The amount of power entering the circuit is the same as that leaving, minus losses in the conversion.
Arghh iv been looking over lots of vids to find the info i need but i cant like what type on transistor what type of resistor , so i can make up my shoping list
What is the point of this video? Which scientific reasons do you have for posting it? Is this a more energy efficient way of making an LED light up? If so, I have seen more efficient ways, using a high frequency pulse generated by an IC, power consumption is less than 80 micro amps !!
Posted several years back, in Elektor. I did not believe it, built it...and it works !! I can't explain how, but the LED lit up quite brightly. That is power efficiency !
@telescopereplicator Because the voltage is generated by inductive kickback, and limited by the LED's forward bias voltage rather than the emf of the cell, the LED will light fine over a massive cell voltage range, so you can run a cell waaay down. Cheap circuit which gives you a use for otherwise dead batteries basically.
@93tomb ..Ahh...it's THAT kind of generator. Now I understand. Now that LED's are getting brighter and more energy efficient by the day, in combination with this circuit enormous amounts of energy can be saved.
@telescopereplicator I know, I saw some LED light fittings running in a hardware store the other day, thought they were halogen when I first saw them! LEDs are the future for sure.
But like, umm, is it legal? Will the thief for stealing something? If so what has the joule thief stolen? A joule? Light? Play-dough? Is it OK to post such video's on the web? What if everyone starts stealing joules, what then?
Besides improving your pronunciation, you should add the capacitor in parallel to the resistor; I used a 10nF ceramic capacitor, but some circuits include a 470pF one. Just try. Anyway, it's a good didactic video, well done.
Super!

What burns up if you don't put in the resistor?

@luckyfire3 the transistor, probably.
if the battery is powerfull enough that is.
probably not in this case

the battery is up-side-down. representing a duracell, the copper top is +. current flows from - to +.
