@all,
Ohh boy, RF, smokin parts, ohhh lookout, getting into energy here that I'm not so sure of.
I think we need to sit down and do a bit of research on RF energy and see if precortions need to be put in place.

@TinselKola,
Welcome to our little Joule Thief forum.
I see from your post you have done a little donut winding ha ha.
Thanks for the above post, it has served a timely purpose regarding RF.

I know in the design of RF PCBs the layout for parts and copper tracks is critical for the operating frequencies, and they have small earthed boxed covering tuned sections in TV tuners, hmmm
But this is about all I understand about this.

@stprue,
Nice double torids wound as a Joule Thief, would you get better results from this if you made the bifilar windings out of tripple wound wire?
Worth a try in this case, just to see what occurs.

I had several double toroids here which I posted pics of quite a few pages ago, did you see them?
Well done with the double T.

@Jeanna,
Thankyou for your kind welcome back, TA muchly.

Double toroids, mabe you could try the same as stprue has done, but see if those badies, the blue toroids you have there can be made to work? (only if you want to of course).

@ Thaelin
I got your PM ok, no worries, but when I went to reply, I couldnt.
A Red cross screen popped up, I clicked the OK to get rid of it, then a white screen opened, I clicked the blue arrow to get out of it, then screen appeared to reply to your PM.

Then I saw the address name was missing, so I exeted it.

@ Bill,
Im going to tale a serious look see for Firefox and see what happens when I install it.
Im using IE7 right now, hope I don't loose anything.

If I get this thing to work and I get decent results I will give that a try.  Thanks for the advice!

@ All:

I just uploaded another video to youtube:

This is my earth battery running a joule thief and lighting 4 ultra bright 10mm 28,000 MCD LEDS to full brightness!!!  I think I can light a lot more.

This is still just a regular JT although this time I made one for this circuit with a toroid instead of a bead.  This is so cool!

Jeanna, you are gonna have fun with this over the summer I'll bet.

Bill

This is really some great progress, pretty soon you will be lighting your house for free

Some questions...

How long do the earth batter materials last?  Since they are in the ground.

I'm sure you have ansewered this before but what is the amperage on your EB?

Hi all:

After that the kodak circuit not matched anyone here, I decided to buy a ferrite toroid core.
Now I got a 58mm outer 40mm inner and 17mm thick ferrite toroid.

I researched an read a lot of messages of this thread and other forums, but I don't know where to start.

The questions are...

Bifilar or Trifilar?

Gauges?

I used a screw to wind the wire (#28) to pass through the hole, but if its bifilar how should be done?

Thanks!

Check out the JT diagrams section, there is a lot of good info in there.
