Joule Thief

WOW very cool...I ordered some stuff last week that will be in on Monday to test out this circuit>  I cant waite.  So you have replaced the trigger coil for a stiffler tower coil that has an extra coil on the inside.  are you getting anything off the AL foil in the left side of the video?  This circuit seems to make anything metal a receiver ie the outside of the batteries!  What was the MA draw? and di it change when adding loads?

nice work

In the last video I wasn't using the Alu foil on the transistor base.
But it will light off anything conductive like metal or water if it's in the fields range.
The current it was using with one battery was around 36 mA I havent checked it yet when using two batteries.
The batteries in the meter were starting to die so I didn't show it in the video.
But the current draw didn't really change after load with the one battery.
I still have one coil to make and I'll get a new set of atteries  and show the current draw in the next video.

@slayer

Nice video , great work as usual , two things come to my mind , first it really look like a tesla coil, and second the base plate (connected to the transistor base) and the emitter coil coil action makes me thinks of tubes.

I was thinking about my latest tube jt , i may try to place a piece of aluminum , connected to the base of my transistor , and use my tube coil to generate a field over it , so the aluminum act like one anode the tube coil exciter then like in a magnetron antenna to (cathode ).

@all

I just managed to buy some new bulbs , they are 2v 49 size bulb(they seem to be used in the auto industry ), i will try then on the secondary later on , i will make a video soon lighting them and also running a motor .

Looking forward to seeing your video.
