Joule Thief

Also Bill...try a magnet on the opposite side of the tube from the first magnet...a couple on the first tube wouldn't hurt either, using various polarity arrangements.

I am intrigued that you have a magnet having an amplification effect on electricity.

There's a lesson in here somewhere.

Unfortunately now you're stuck buying more tubes to find out where the limit of the system lies.

Regards...

bill awsome.... work



and cap !!!


lol

miles in days  light years in weeks.....

here is an easy circuit to replace your aa or aaa. use a step down transformer to get the ac from the wall down to about 5v. it might even run from usb off your pc.
any low dropout voltage regulator should do. i used a upc2933.

Magnet causes bright spot on tube because it pulls the stream of ions from the center of tube causing more of them to hit the phosphorus coating on the tube (more ions = more light). Transformer sound may not be getting quieter, it may be getting higher in frequency (going above audible). Higher frequency is good if that is what is happening, because more energy will go through a given capacitance value at higher frequencies. Thus it is easier to light tube with only one wire at higher frequencies. To see if C or D cell will harm circuit, check the current draw when using AA battery and D battery. If current for D battery is not significantly higher than AA battery  then D batteries are safe to use and will last longer.

Here is a video I did showing my Joule Thief. I got around to making one and it works! 
That was such a cool feeling hooking it up to a battery right after soldering it all together and getting this crazy bright light from a tiny LED!
I know I am WAY behind everyone else on this, but I thought I would share my beginner's success.

@ ist:

Thanks.

@ Wilby:

Nice circuit.  Hopefully, I will give that a try.  Then it would be easy to make our own led bulbs, or run these tubes from the wall power.

@ Timmy:

Nice job on the joule thief and the video.  I saw where desertphile attacked you in the comments section.  From his comment, he obviously has no idea how/why this works so, just ignore him.  When I power my circuit from my earth battery, it will indeed be free energy or at least free light.  I will make (hopefully) a video of that and post it.
