well

if you had a septate ... tuned curcuit  you may be able to swip a magnet past it ...  to charge from the colapse ...   for the first charge....


i recomend some have a look at this fourm .... 

naw i never read it all i already wear mine ....

out of the blue and because you guys LOVE to wind coils and try different ideas 

Rogowski Coil - thank you to BEP!

@All,

My experiments were basically Rogowski coils with one end passed through the center (as a flat spiral - 1 or 2 turns) and the outer winding wound around that core 360 degrees and then reversed in direction and handedness the full 360 degrees.
Highest frequency division is found with fewer spiral turns.

The number of cancelling outer turn pairs should be an even number.

Spacing between the core and outer wrap should be at least 2.5 times the diameter of the conductor.
Spacing between the turns of the outer wrap should be as close as possible and less than 2 times the diameter conductor.

The results seem counter intuitive. The lower the inductance of the core gives a lower resonant point.

I believe the outer wrap is creating induced nodes and antinodes on the core conductor. 'Squeezing the hose' or pinching, so to speak.

It is possible to have a spiral coil that should resonate at 30 mHz (overall coil capacitance is increased) and find the coil current 'dip' (drop) near normal resonance divided by the 1/2 the number of cancelling outer turns.
Or even much greater.

There, I've shared details on the most easily repeatable result I've had these past couple of years. 
To me, this explains the strange 22kHz resonance of experiments by others and extremely low points found on my other tests.

If you try this please be aware if you create a resonance that matches the mechanical resonance of your core there will be mechanical movement. Mine broke a pane of glass I was using as an insulating surface on my workbench.

Since the magnetic field is well known to be concentrated inside winding of a toroid this idea may be part of a TPU function. I can see a magnetic field rotating about this axis.

BEP 

5000Hz can also mean 5000 RPM so it must be like a generator with a virtual rotor. Albeit, the 'fields' mentioned are not described as magnetic.
I hope we do too. I don't think we will if we continue thinking about moving a simple magnet over a piece of wire. That is the weakest way to cause current flow with a magnet. The strongest way is to align that magnetic field radial to the wire. Then rotate it around the wire at very high speeds. 

Therefore, the 'core' is a conductor or air AND this conductor is in the center of the TPU. This conductor is created with the operation of the TPU, NOT part of the assembly.

How do you think he could measure current with the clamp meter with no wire in the clamp? Try it. I have. The only way to have a reading is with a current carrying wire inside the clamp or a large change in the local magnetic field strength (also, assumed possible if you had current flowing through air).

I think the TPU is nothing more than a means to emulate the action of magnetic fields around a current carrying wire. When running it causes current to flow through the vertical axis of the TPU.

To tap this potential he adds a Rogowski coil all around the TPU (constant voltage output) and we have confused this coil to be a control coil. The only control coils are the ones on the outside placed in quadrature positions. The FTPU and OTPU use a slightly different method.

 
With that thought in-mind consider this:

You CAN stack Rogowski coils on a current carrying wire. AND you CAN connect them in any method you choose to increase voltage or current output. AND you can have as many as you want.

Our terminology is wrong. The 'collector' IS the complete TPU. The loop in the middle is just the return wire for the Rogowski coil.

While the above is only my opinion I am quite certain I am correct.

Here is a good explanation:

@ jeanna

Please all those who have managed to turn a fluoro on with a toroid... I need some help here.
Probably help with the obvious.

Why don't you try to EXACTLY duplicate a circuit that was shown to work. You always seem to want to try something different instead of doing what is known to work. I think you have all of the parts that hazens1 used except maybe the TIP31, but a 2N3055 will work as a substitute. And someone said the TIP31 was available at RS.

that's the best finger pedal i have seen, by far!
