Joule Thief

[electricme]

To groundloop and others, some background

OK this is my setup at home showing my power from the ground, its only tiny volts.
I have an idea about using Jule Thief to boost volts to drive other small things.

Photo0066 is my Joule thief I made this morning
0067 is the waveform, cro was set on Volts/Division = .5   Time/Division = .2uS (micro seconds)
0069 LED Switched to Red LED
0075 LED Switched to Green LED
0074 toroid I wound this morning, wire came from a microwave fan motor coil. 30turns bifilier (not 20T)

OK next series are of the NS stuff I have been doing, this consists of Copper rods or in this case a sheet of copper berried in the ground, along with Carbon rods (5 of them) they are the separate Positives (+), the Iron plate and the Lead disk being a combined Negative (-).
So what I have connected to the "orange lead" is Green wire a common Neg and the Blue wire, a separate Positave and the Brown wire, another separate Positave.

see 0080.jpg
0078 shows the broader setup.

This is where I want to ask a question, I notice Bill asked this in a previous post here.
Is it possible to use a number of Jule Thieves to get a higher output by ganging their outputs.
Should we use a trifler wound torrid? or a quadbifilier winding?
Should a inverter circuit be used instead, or a combination?

I apologise for hogging the space, If this is not meeting the joule thief forum, I could setup another joule thief forum.
What say you all?

@ Jim:

Nice to see you here.  Feel free to post all you want, whatever you want.  You always have some good stuff.

Well, you beat me to it.  I have been wanting to get outside and hook one of these to my earth battery but have not had the chance. (yet)  I was getting enough to light my leds before and with the JT maybe I can light a handful of them.....FREE!

Nice scope shot.  I am not sure but I think your transistor is more heavy duty than the ones I am using. (3904)  So, as someone said on here, you can probably get away with a series hook up of several.  No telling what might happen.

I got my color organ up and running.  I have 2 strings of 100 leds each and I need a third for the 3rd channel.  It should be really cool.

I really miss being able to go back when posting and see what folks wrote.  For some reason, I only can scroll down and see the last post.  I know you said some things in your first post I wanted to talk about, but I can't see what they were.  For guys like me with a bad memory, this is not a good thing. (grin)

Anyway, great to see you here.  Keep us posted on the earth battery/JT experiments.  I will do mine as soon as I am able.


Thanks to all who commented on my little LED water bottle lights.  My neighbor suggested using broken glass fragments instead of my glass marbles.  (my marbles are not truly clear, sort of opaque)  He said he saw it on the net somewhere and it really breaks up the light and looks cool as well.  I will try that when I can.

i saw something similar on instructables, it was featured in their 'get the LED out' contest.

have you tried adding bleach to the water like those guys in that thread awhile back. http://www.overunity.com/index.php?topic=4878.0

here are a couple nice JT projects kids might enjoy.

and here is another 1.5V to 350V inverter.

unrelated but one of my personal favs among many on instructables, flaming mini-marshmallow projectiles get me every time...
