Joule Thief

@freezer
That is what I have been trying to do lately.
I tried to put together 2 camera circuits to get a brighter ligh and I ended up with several circuits damaged, Including the first one with the neo bulb.
Now I have to start all over again.

Congratulations, You did a great job! Nice video!

@wilbyinebriated
Thanks for the circuit. I already have built the antenna. I tried with my circuit of taking energy from the air and it did not work. I will change the 3awg for a 26awg, because it is too thin and difficult to connect to a breadboard. It loses connection.
I will try your circuit as soon as i can.

@innovation
Those were big sparks on your video!

put a number of diodes off it

I tried to replicate your circuit. But my 4 watt bulb only lit up very dimly. Not anywhere near as bright as others seem to be getting. I tried using 100 ohm and 500 ohm resistors and results were the same. I tried 3 volt battery and not much difference. Open circuit output voltage with 1.5 volt battery is about 300 volts. Open circuit output voltage with 3 volt battery is about 500 volts.

Thanks and yes, they a Ne2 colored and 1 regular Ne2.  The great thing about this is that its already built, all you need to do is remove some components and solder some on.
Thanks, yea, you can hear in each one of his interviews that he doesn't want to talk about anything, and that he's interested in the money.  I still think he knows how to do it, but not willing to share that information, even if you do pay him.

I made small video for youtube about this joule thief. Added a 3 way switch to go between 2 neons and an output plug.

Found another 23w fluorescent bulb and it lights.

@ Freezer:

Very nice, neat little package you made there.  Nice craftsmanship.  I am off now to check out your video.  That is a good amount of light from just a AA battery.....well done!

  The following circuit is much brighter than the circuit in my previous post. I removed the diodes and added a 30 pF capacitor. You might want to do the same. Still not as brite as Freezer's circuit. I hope he will post it. He seems to have the best performance.

EDIT: Also works from single 1.5 volt AAA battery.
EDIT: Larger capacitor values seem to work better. May be voltage and circuit dependent.
