@stprue

Have you tried it with the coil inside the toroid , or both on one toroid.

@all

I new idea would be to make a motor jt , a regular toroid would not work because the magnet would be attracted to it , i made some jt from 1/2 inch copper tubing that worked real well , like basic jt .

So we could have light and recyclable movement for free , just think of the rodin coil with a sniping magnet on a smaller scale . http://www.youtube.com/user/Lidmotor#p/f/3/Sahi7zDf8Mw

We could make those coil on a card board flat ! or a copper washer ...

Think about it !

I will wind one as soon as a get enough wire for the 12*2*15 = 360 turns it needs ...

Thank you Xee, Jeanna, stprue, MK, IST, Stefan, Gilobob, I really appreciate it.

Wow, the lights got very bright when you held that above the other.  Do I see that your wires are wound around the circumference of those toroids?  I didn't know we could wind them like that.  Are they still bifilar?  Or just straight windings?

@ All:

I contacted the supplier of the large toroids that Gadget posted a while back and asked for a quote on them.

I am also filling out a request for some free samples to see if I can get some of these for my Jeanna Light replication.  I will keep you posted.

Thanks again everyone.

It's a good idea Mark, I have made an air coil with 2 windings but that has been posted in the Bloch Wall TPU topic. I got over 300 volts rectified off of coupling alone.  I feel that JT and TPU are both good to study and learn from

i just came up with a real easy steel ring design ...   

mk1 do you think that cutting a long grove in the core where the pick up windings go would help to release from the iron? 

if this was the core

i may have to build it test it and see ... seams to me it should work well

That is 1 wire 18AWG wrapped 6 times around the TOR clockwise...each one that is!

I through in a couple of small value caps a 102 and a 221 that is.  Not sure if the caps matter yet...still testing.

My power source is 5v @ 1670kHz, but I have no further data because in the video I just posted I blew the fuse in my DMM. I think it was a 20 AMP fuse...not sure how it happened but I think it might have killed my nice DMM.
