Joule Thief

[Mk1]

@electricme

I wish i did post some pic,because it's required to be taken seriously , but i don't have a camera and not planing on buying one but as soon as i will find a way i will post one. There are so many things i have to show you, but you should all tried to do it anyway you will learn so much more, find it for your self it you can make a standard joule thief you can do the same with a transformer , personally i don't think we have time for challenging the validity of finding but barely enough to to save our self, may that time be spent on testing . 

Also anyone that made the joule thief ad 2 more wire of the same gauge around the toroid and put leds on them how long could it take to get it?

The crowd that say it cannot be done, never tried. stop preaching start living.

@ Pirate88179  and others interested

  I decided to risk running my Fuji AA board at a higher voltage. I ran it at 3 volts using two AA batteries in series. But only for 5 seconds at a time. The board was not damaged so the transformer is able to handle the higher voltage. I doubt that the transistor will survive longer runs though. The tube more than doubles in brightness. So, it is possible to get the tubes to light brighter by using 3 volts. To do this without frying transistor would require replacing the transistor with one having a good heat sink. I no longer can see well enough to do this, but someone else may wish to try.

EDIT: Draws 2.3 amps at 3 volts so should pick transistor able to handle 6 watts.

@All
I was wondering if we could get more power out of a Darlington transistor setup, using Power Transistors.

One reason for using the smaller transistors is they have a higher hFE factor then power transistors.
But the Darlington setup will take care of this.

sure just solder in some wires, if you remove the little silver metal tab thing (i think its for the shutter) that will give you 2 holes to choose for ground. if you remove the diode that would give you a hole for the positive to the bulb as well. i just used alligator clips to test it out.

@Wilby
Excellent! Thank you!!!

Darlington should work. Doesn't have to be a power transistor, just needs good heat sink.
