@buzz-ard


Can I ask how you are driving your control coils? I have a similar setup and am collecting output to use as feedback but the mosfets I am using to drive the control coils causes a severe voltage drop. I have 5v from my oscillators but the mosfet drops it to 1v. My mosfets are bs170.

Any thoughts are appreciated.

Here is some more information on my setup.

Thank you.

Here is a tpu experiment, using 1 ONE O-N-E control coil that I imagined, then had to build. Novel as all heck.

Here is a pic:

I call this my "Wagon Wheel" TPU. It has a bifiliar wound 30ga collector of four turns, inside a small solid aluminum ring. Both ring and collector are taped together.

The control coil, also 30ga is spiral wound clockwise around the entire circumference of the TPU collectors. (Plural as the ring itself is a passive amperage amplifier for the bifiliar in theory)

For size comparison of this tiny beauty, the TPU is setting in the pic upon an ordinary roll of black tape.

The beauty of this design is that the field has no choice but to rotate, irregardless of the input signal, so long as it is DC in nature.

I have had some very interesting results which I documented for you all, 8 scope shots in all:

First scope settings and pulsing system:

All but the closeup -> 2microseconds time/div at .2v/div
Closeup -> 1microsecond time/div at .1v/div

Osscilator circuits used: The real beauty of a tiny tpu is that I can drive it diectly from my two function generators.

B&K on one isolated wind from the bifiliar collector. Piece of junk on the control coil. (Sorry, did I say that? )

The pic above is of one wind of the bifiliar collector coil only pulsed with square waves at 2400 Khz (2.4 Mhz).


(http://www.geocities.com/pauldude000/tpuwheel/ww2.jpg)

The pic above is with the outside control coil only pulsed at 2110Khz (2.1 Mhz).


(http://www.geocities.com/pauldude000/tpuwheel/ww3.jpg)

BOTH the collector, and the control pulsed together at approx 9.8v(control) and 12v (collector)
This one demonstrates full harmonics. I do not know how it comes through in the pic, but there are sines superimposed upon the square wave, with the strongest signal being PURE SINE AC. This has me stumped!

Here is a closeup of the wave from the last shot showing full harmonics.

Why different voltages between signals?
I learned something......
This pic above is the output at the SAME voltage. ~9.5v


(http://www.geocities.com/pauldude000/tpuwheel/ww5.jpg)

I learned something else.
The duty cycle, or DC offset, Makes a HUGE difference in output characteristics.
The pic above is taken with the DC offset of the control at min (minimum duty cycle, or short pulse.)


(http://www.geocities.com/pauldude000/tpuwheel/ww6.jpg)

However, without the second signal into the collector bifiliar, with the control dc offset the same in the control, this is the result! This is interesting as it appears a 50% duty cycle approx, yet is SHORT DUTY CYCLE square wave input!??


(http://www.geocities.com/pauldude000/tpuwheel/ww7.jpg)

This pic shows what happens at 9.8v and 12v but at one frequency -> 2110Khz. Notice some resonance reaction, but nothing like the resonance of the coil to slightly differing frequencies.

What have I learned from this, and another tiny four coil unit made with an identical ring and single collector coil, and the other coils I have made tested and ditched?

1. Resonance is not enough by itself.
2. Rotation is not enough by itself.
3. The output characteristics from every coil tried so far increase dramatically with higher voltage. 9v by itself is not enough. It must be raised to a higher potential.
4. >>>>>>Rotation is an absolute necessity<<<<<<, not merely a possible.
5. Pulsing of the collector in an isolated leg of a bifilar should be tried by all!
6. Using a Steel core is worthless. If anyone has had luck with steel or ferrite cores, give me the info. They detract from performance as far as I can see.
7. Frequency of operation for any given coil is IMPERATIVE. All of the coils tested have "sweet spot" frequencies. They may not even produce much of any output too far from a "sweet spot" (natural resonant frequency of the unit).
8. Pulse length is important.

9. This small coil scares the poop out of me, and the tiny four coil is worse.

If they were full sized, pulsed with say 50v..... OUCH! (Who am I kidding, if I were to pulse them with 50v NOW I have no clue what the field would do, or how strong it might get. It tries to explode at 12v, and feedback kicks in my B&K's safety circuitry if I turn to 15v for more than a second or two.)

I hope this gives some here some interesting insights.

Hello all,

@Paul

can you get somehow a deflection coil from a TV?

If yes, then use the coils with a core from this system. There are 2 of them. This are the outer coils. Connect them to your TPU and see the signals.

Otto

Hello all,

@Paul

I use this 2 coils in a series connection as an input. This means, to be clearer, I hope:

MOSFET - 1 coil - output from this coil to the control coil of the TPU. The same with the other MOSFET and 2. coil.

Have you tried to pulse only the collectors?? The controls NOT connected.

I see biiiiig nice signals.

Do we need tubes?? Hmmmm.....our teacher told us to use them.

But why?? Yes, yes, I know. Im building tube oscillators!! One day they will and must be finished.

THE ONLY REASON IM BUILDING TUBE OSCILLATORS IS THAT THEN I WILL BE ABLE TO PULSE MY COILS WITH FREQUENCIES OF 2 OR EVEN 3MHZ.

With an additional coil as we see them in the videos, the little one in the middle, we have nice, clear signals of a lot of volts.
May I say like with tubes??? Yes.

The tubes are more easy because of two things:

1. You have a high voltage signal.
2. They are fast.

When you do use Mosfets use them in combination with capacitors charged to high voltage and the saturable inductor switches this sharpens the pulse and the caps deliver the needed high voltage so you will end up with something that looks like the tube setup.

Great post, Paul! You and I are parallel in many of our observations. I'll throw in my two cents here, at least until I get my page built:

1. Resonance is indeed not enough. All of the results I've had so far have been strictly through resonance, but quite interesting nonetheless.
2. Rotation is, I believe, part and parcel of the effect. By itself alone it's not enough, I agree.
3. I'm not certain that initial high voltage is required. In nearly all the good results I've gotten, 3 Vpp from the function generators has been my reference level. When I increase voltage I get the same effects, just with higher peaks. I've gotten 200 volts clean AC sine from 20 V DC square offset negative out of my B&Ks, but after thinking it through it's meaningless because I'm relying only on resonance - I've really only been playing with basic transformer effects, I think. Seems voltage and current build in SM's units, so a minimal input should suffice to get it going (9V battery, two AA batteries, etc.).
4. YES!
5. I've had much fun with the bi-filar approach. This is definitely part of the working design. Use the spare leads for feedback into the control coils - it may also drain off some of the feedback getting to your B&K. I've had surprising results using feedback.
6. Iron/steel in the core does not seem to help, I agree. It makes a huge difference in the Tesla replica, though. I have a build planned using a steel core, where intend to saw it multiple times and leave a 1/4 inch gap or so, making it segmented so as to create separate poles within each control coil region. I will wind this build in both Tesla/AC and TPU/DC fashion to see the effects of the split core, but I expect it to benefit the Tesla configuration the most.
7. The sweet spot has been easy to find and easy to tune in my builds. I do believe there's a cascade/avalanche effect that will occur when it's all lined up. But I've found that there's usually a really narrow range where things happen, so precise control of the frequencies is imperative.
8. Pulse length is important. I've had the best results at 50% duty so far, but again I've been tuning for resonance. I've also seen square waves superimposed on the sine traces (really strange-looking indeed), but these are just noisy artifacts that disappear with more tuning.

A thought for all: Turn your function generator way up high then scope the output - there will be what we used to call "switch-bounce" as the output drain stabilizes, showing squiggly traces that settle down after 6-8 oscillations. You can also see switch bounce in stereo gear, like when you turn on the power (the "kick" and thump from the inrush of current, which stabilizes after a few cycles). This squiggly bounce is supposedly not a desirable thing in the TPU, as the squigglies would cause ripple in the resulting mag field and distort the effect. Squigglies are more pronounced at higher frequencies, illustrating one of the trade-offs of using SS devices. Tubes generally don't do this as badly, nor do continuous power sources like batteries. Spark gaps do something similar as I recall, but it's much wilder and even more destructive - this is why I had so little confidence in the reed-switch-as-commutator idea that was floating around in another thread.

Check your junkbox again! (at least yours are entering in through the hotmail inbox now!)

@all

I am going to try to link the logical thoughts here, for both you AND my own mind.

The first input signal creates a field. The second harmonic resonant signal attracts the lines of force before collapse from the first, drawing it toward the second in train, giving apparent motion, IE rotation. Thinking about this, all frequencies should be a narrow but powerful pulse to spin the field up.

A third stabilizing frequency would be good at this point, to maintain and speed up rotation. The rotation then is resonant with the applied signals, but probably at a much lower frequency (a sub harmonic). Our coils are wound wrong on the collectors.......

They should probably be laid literally one on top of the other, each wound fully around the circumference of the TPU and pulsed sequentially. (inner coil -> 0 degrees, second coil -> 90degrees, outer coil -> 180 degrees phasing). This will give a massively rotating field.

With my "wagon wheel" TPU, I learned some VERY valuable insights on this, and it matches precisely with SM's own description of the build of his coil.  (I am glad I tried the "wild hare" approach on this what I thought of as non-sensical wind.)

I think sharp spike cap discharge through mosfets is the way to go frequency regulated by square wave oscillators.

Find three "sweet spots", for your coils. Write down the center frequencies. Build one oscillator for each coil at the specific frequency, lowest to highest. Have all three switchable. Fire the first low frequency, then fire the second, (if I am right, you should notice a small output here) then fire the third..... Manually firing the frequencies should do the trick, as it is almost guaranteed to be out of phase this way. (Being IN phase would be sheer accident.)

If my thoughts are right.... MAN OH MAN I THUNK I HAVE HAD ANOTHER MENTAL BREAKTHROUGH!
