Here are a few more items from previous posts that might be helpful.

Check for edits, we seem to be posting at the same time.

The floppy disk drives are a pain to get apart, maybe I have inferior 'refuse' laying about, but haven't gotten one worth keeping, on top of this, they're slow, remember.

There have been studies about the gauss strength of magnets, you may be able to create a very powerful motor with very thin magnets to maintain the profile.  I believe that the thinner magnets are just as powerful at their poles as the thicker ones of similar other dimensions ( length and width ).

well the idea was the slow drive shouldent that out out power at lower rpm's ? and to the magnets bit erm brain fart A
floppy drive are easy to take apart if you know how but what i got was a flat unit with a flat unit disk under that they was a 12 pole stature wired in 3 phase messed this one up and used the wire for testing joule thief but next one i with cut the tracers and solder 4 wires to board for take offs and will find out then how good it will work

@ xee2: thank you, that was nice! It is so difficult to find something in this heap.

@ all:

I found a very interesting Joule Thief variant, which was posted by a person calling himself Groundloop2003 (I forgot where I found it, see the image below). This circuit reduces the base current and seems to give very high frequencies (I got 1.2 MHz).

With this circuit I built a very low power Joule Thief which lights a single red LED with a strange “cell” (of course with an air coil).

The cell can be seen on YouTube, someone made a cool video about such cells (which inspired me): http://www.youtube.com/watch?v=FGdpa3GKN34

There is also a thread about these cells (which I read before I built the cell): http://www.overunity.com/index.php?topic=972.msg243194#new (Crystal Power CeLL by John Hutchison)

The Cell:

0,3 mm Copper sheet 120 x 120 mm
2 mm tile cement
0,5 mm Aluminium sheet with little holes 120 x 120

Some people make very complicated mixtures instead of using “tile cement” (which I had in the house for a recent tile job in my bath room). I just wanted to see whether I get any current out of such a strange thing; and contrary to my negative expectations, the “reduced base current Joule Thief” gets enough electricity out of it for one red LED (a white LED needs too much and does not shine with this cell). An ordinary Joule Thief circuit might just blink a red LED with this cell if the base resistor is too low.

The cell produces about 0.2 to 0.4 mA at up to 1.17 Volt.

Greetings, Conrad

ok here is my idea a joule thief running off an earth battery to power a pulse moter ok easy enogth i think you will say but how about using the motion of the pulse motor to turn a modified cdrom moter into a dynimo aka 3 phase generator as i see it this would give the higher amps needed for larg battery charging what you think i dont have a clue were to start this for any up for it

I did that last year, check out my videos.  I ran a Bedini  motor from my EER or earth battery.  I have been using supercaps with my EER for some time now.  It is a good way to capture the high spikes and preserve them for usable power.  it works really well.
