good work wattsup,  aluminum wire hum?  I'll have to try that.

@wattsup!
OMG I am the biggest fool!
Bruce-tpu sent me 2 - 15" 3 layer coils this summer.
And guess what? The bigger loops are copper lamp cord and the loosely wound control coils are STEEL! I didn't think I hand anything. Yes, Square pulses and aluminum are a HF mix! I you hit the aluminum with VHF and above the Alum is going to react.

This may not be of concern here, but there were some pro audio speakers, EV, that used aluminum voice coils, but considering the freq Watts is using, maybe its nothing. Also in high tension lines they use aluminum. From what I know, they use it instead of copper for 2 reasons. 1 its cheaper, 2 its lower conductivity does not stand in the way of the high voltage used there. Or is there another reason aluminum is used in these situations. ?
Very cool Watts.

Hope them coils work out.

Here is my new toroid, well my soon to be old toroid because this one is just to learn a few more things about the ftpu. lol

This one is as follows;
Photo #1
3" core T-300-26
Secondary 112 turns each of 24 awg
Secondary wind mode - bucking
0,8 ohms
Photo #2 with transformer wrap.
Photo #3
Primary 32 turns each of 20 awg
Primary wind mode same as secondary
0,3 ohms

But I am already planning my next toroid. It will be aluminum core with one slit cut into it. Each end goes to two of the toroid wires. Then cover with 32 turns x 2 of 20 awg.  If the center toroid did in fact have only those two visible coils, then the core would have to be an aluminum ring with a slit from which you can take aluminum wire that then goes too the outer aluminum rings. Only time will tell. But these are so fun to test out and learn from. That would give non-magnetic toroid core and non-magnetic outer ring. I have to find some aluminum cores. Then paint them white. lol

I need some help with the EE end.
If you have the above coils with their ohms value, can you calculate the capacitor values I would need to pulse this with a transistor or mosfet at 5000 hertz. Eventually I need to not use my pulse generator and make this a stand alone trials.

Just thinking about the spin up of the compass and coils of high selfinductance and longitudinal waves.  If we induce a voltage into one end of the coil wrapped around the core does a longitudinal wave travel through the copper mass in a given direction.  In other words the coil of highselfinductance is like a pipefilled with electrons. On one end of the pipe we inflict a hammer blow.  The hammer blow creates a shockwave that alternately compresses and rarifies the liquid.  In this case it compresses and rarifies the electron cloud of the coil of high self inductance.  A sound wave travels in a given direction from the input pressure zone around the ring.  The electrons when all compressed up would display a higher net negative charge as compared to the rarified part.  As the wave passes the start point in the ring we wack it again.  Round and round this compression and relaxation of the copper electron cloud goes. The coil of highselfinductance is just an electron cloud scource to pass the longitudinal waves through.  Not from one end of the wire to the other but sideways from turn to turn.
