Joule Thief Bedini Motor

@ Pirate:

   Hey that vid is of John Bedini himself. Its one he did a while ago.

This was posted on another topic.  I didn't know if you had seen it.  Bedini motor operating off of a large cap, no batteries.  Stick a joule thief in there and who knows?

Hi,some people have asked for details off the ferrite i am using so here are some close up picture's.
The dimensions off the ferrite
lengh 27mm
OD-26mm
ID-13mm
There are 10 bifilar turns using singe solid core swg 23 bell wire.
The diode's that i have tried and found to work well are 1N4937 and 1N5408 and there may be others which work even better.
There are people on pirate's joule thief thread who have designed high output joule thiefs which would be ideal for this application also.
Hope this helps.

That looks exactly like the dimensions of the ferrite bead I used for some of my breadboard video experiments.  (see videos on youtube)  I used the bead as I had no toroid shapes to use that were actual ferrite and not powdered iron.  My thoughts are the more mass, the better whatever the ferrite is doing will be.  This may not be correct but, what do I know? (ha ha)   Great pics.

Hi.Lidmotor from the energeticforum has made a joule thief Bedini motor.It is looking really promising.
Take a look at the video he has made.

@pirate.Hi Bill. I think it is the same toroid as you used.I have only made 2 jt coils and this was my first one.The 2nd one was using a small feritte out off a cfl and the performance is no where near as good as the cylindrical one.

I finally got in my parts to complete my Bedini motor and I will also combine this with the joule thief circuit.  I had to buy 50 transistors so, I have some room to play around and blow a few.  I am looking forward to this.
