Cools, looks like bloch-wall micro-variations causing plane shifting in the pickup.  Be nice to get a better diagram.

Nice work slayer007! I have been charging batterys with my Joule Thief but it will only charge 1 at a time. i can run A and a small motor at the same time as well.

Have you did any tests to see if your charged battery's are experiencing empty voltage? I know my battery's will charge to a full 1.33 volts but not last as long as if I used my wall charger but yet they get the same voltage.

Keep up the great work!

Yes and No lol.
There was two bad batteries in with the 10 that will not hold a charge.But there over 3 years old and they don't hold a good charge with a conventional charger.
So they were replaced with newer rechargeable batteries today.
I also bought 2 small 6v sla batteries today.I would like to run it off a 6v battery and charge the other two batteries while running the led's.
you can find the circuit for this a couple pages back.

Thanks. Excellent demonstration. I am not sure what is happening, but the magnet deffinitely helps.

Thanks. Excellent demonstration. I am not sure what is happening, but the magnet definitely helps.

It seems to work like the orbo , and the solid state version , to some extent the MEG , i think the basically the theory suggest that the toroid and its coil disrupt the magnetic form the magnet , so the pickup coil is under stress from the magnet at all time except when the toroid is triggered , so the change in the magnetic strength induces voltage in the pickup coil .

I hope my explanation helps .

Wow that's cool. I don't have any small diodes like you are using will 1n1004s or something similar work? I have been using 9 volts on the CFL driver is 5 volts recommended?

Thank you so much for the help!

Mine says 5 v's so thats what I put in but you can put in a little more or less!
