Bloch wall disconnect and reconnect. The final design!

SM said 5khz after I posted the the SM17 was a stun gun. There are 2 of those ckts in that box. The big yellow rounds things on each side of the box are the same in a stun gun.
Believe me, I had extensive clues and warnings thrown at me.
Guess what drives a stun gun? 5khz square waves! He just replaced the output probes with loops! Did this 3 years ago. Was gonna throw a 15 foot diam loop in the yard and he told me 'No!'. FAA problems.

@h20commuter,
I would still be interested in any pics you can retrieve. We have all, at one time or another through this, missed something.

Handwound core. Could have used 2 turns of speaker wire also.

Nice giantkiller 

My proposition : make a coil UNIDIRECTIONAL.How ?
Unfortunately I can't draw a schematic but it hast to be that way :
wound one turn in normal style around coil core (which has to be torroid and you find why) - then make a small choke like coil around in the same direction 90 degrees from the first turn, choke should then become second turn and so on .... Keep in mind using only ONE wire.

Can someone depict this idea in the form of schematic ?

@Forest,
So you are saying no 2 bucking coil configuration?

And my assessment is the core is copper?

The attached pic shows a straight run but That will be in a circle to the match Smith's and Mark's rings.

Is this what you are thinking?

That would match my Sport model previously posted. And the center toroid is an exact match at a smaller model and lower drive specs?

As I have shown I have a smaller center toroid. The small ones are easy to build or reconfigure if the specs change.

So by what you are saying my Sport model is a correct configuration and now make a smaller version to drive and feed back the bigger one.

I'll be back in 12 hours.
