well this is a easy test
i have a fork for removeing ball joints in cars strike it with a hammer at the right time watch the results
verry kool
and it gets lould with just 1 freq ;D
might make a vid
ist
now to make a tpu do the same thing but magnetically ;D 8)
ist
1 more real simple way to understand the tpu
put a wishel on a string and spinn round and round the sound you hear is what i would call heterodyning with 1 freq
agin do it magnetically
ist
Hopefully this is a correct understanding :) But one can doubt real easily.
I myself will try the following arrangement somewhere in the future:
1. A piece of magnetostrictive steel or iron something like 15" x 1" x 1", a bar or a ring. The dimensions should be that the resonant frequency falls into audible frequency range (no ultrasonics as they transform into heat quickly).
2. A piezo-transducer (or small speaker), connected to soundcard.
3. A microphone to catch the resonant frequency, connected to soundcard.
4. An insulated (enameled) copper wire that will resemble a "collector".
5. A volt/ampere meter.
I'll also need to create a simple program that can produce sinewave of specified frequency. A possible resonance will be seen on a spectrum analyzer that monitors microphone input.
The hardest thing is 1 - otherwise I would be testing it already...
hello
i was thinking about that ftpu
SM say 7.3 so nnnnnhhh
about 400-500 rpm
make disc what spins and but some magnets
copperwire loop topoff disc ?
funn that dude with cd turbine he say about 400-500 rpm then magnetball rotation will reverse
7.3 =438rpm
7.8 =468rpm
magnet soundbarrier ?
Not sure what you are talking about here, sorry.
I've found a piece of metal yesterday: 3kg iron fillet for physical training. By ear, it rings at some 4-5 kHz (have not measured it precisely). To make things simple, I'll try to use direct acoustic stimulation with a small speaker.
No expectations with direct acoustic stimulation (too little energy is injected into iron) - I just hope to find some resonances and at least measure voltage induced by magnetostriction. But the material may be wrong for this, of course. Then again, electromagnet can be used with more efficiency, because it will basically turn a piece of iron into resonator (iron attracts to magnetic field, hence partially displaces physically, hence acoustic waves are born inside it)
Who knows? "magnetostriction free energy" yields no results on websearch ;) well, results lead to "free energy" in chemical terms - not the same as overunity. "magnetostriction overunity" leads to some links only.
like this ?

I was thinking a lot about the gyro inertia in the TPUs. IMO it has nothing to do about the mass of electrons, I say that he generates short high voltage pulses and fires the coils in series at relatively high amps from caps. The inertia can be attributed to the back EMF and the weight difference between the drivers and collector. It may also explain the cork in the TPU17 that avoids the coils band together.

;D
quoteing my self now lol
ok remember how the tpu does not work until it winds up .....
well u need to speed it to what you want to drive or pluse it or smack it with a hammer ;D b4 you load it ;) no?
ist
im not gonna have to make 1 more real simple video explaining this agin am i??
this works as explained
use a transformer a spark gap and a light bulb
then you tell me it dont work
i mesured amparage yesterday ;D ;D ;D
how much did i mesure on my real cheep meter ??
not 20 amp from a 15 vdc 1 amp supply :o :o :o
ist
of course this was a peek and it was not run constant
enjoy
as near as i can tell it only works when it is hooked up 1 way
be sure to take that into consideration....

this device teters on the operation of the IST REZAP POWER PAC!
when i get to it i will be building this too...

This is unbelievable... Piece of iron (3kg physicall training fillet) I have acoustically rings at 7 HZ! This is f**cking absolutely unbelievable.
I have a proof - just recorded it with a high grade mic I have.
This seems to be absolutely impossible, because it simply does not have required size for such low frequency resonance.
Another sustained frequency is 2.186 kHz, but it may be related to physical size.
At attack stage frequencies like 11.4kHz, 5.475kHz, 6.900kHz available.
EDIT: sorry, it is closer to 8.5 Hz, but still is very unexpectable.
EDIT2: Well, I was too quick with my results... That 8.5 Hz is probably coming from floor, but still it's remarkable how this piece of iron resonates to such low frequency - I'm capturing the sound directionally, it's not just surrounding residue. I'm doing more tests in suspended state. Will post more plots.
Further test indeed show that some acoustic capacitance is present at around 7 Hz. The plot below is a low-passed audio signal of a single strike (linear-phase filter with 90 dB rejection above 160 Hz). I have used a small iron bar (3.5"x1/10") when striking that 3kg fillet - this time it was suspended by hand over the floor (not optimal as well). Well, this may tell little as good acoustic measurements can only be done in an anechoic chamber utilizing highest grade transducer and microphone. But still, such simple "impulse response" test usually tells much. If there were no such 7 Hz bump, the iron would not run into the resonance with building's flooring.
Here's power spectrum of a single strike. Just to let you know these ARE acoustic modes of the said iron fillet. If we consider magnetostriction, it is at these frequencies magnetomechanic coupling will have highest coefficient.
Seems like I'm not so good experimenter. ;) I doubt now that 7~8.5 Hz thing is anywhere significant (but who knows). Anyway, iron's frequencies may be useful - they seem to be close to what was mentioned previously in relation to SM TPU videos.
nice work aleks, I wonder if you have another weight of a different dimention to test. If you do, then we can get a comparison and see what frequencies are dependent on dimentions and which ones (if any) depend on the bulk material properties. (the resonant spikes will stay at the same frequency in that case)

I will try that later - I have another piece of iron, which is also more geometrically complex (microphone stand base) - do not know its weight right now.
I do think, however, that strike does not reveal all possible resonances, but theoretically it's quite OK. It is like a starter pistol when measuring room impulse response. (of course using swept sine is a better thing, but in this case it requires special surface-mount equipment which I do not possess).
HI ALL
@INNOVATION hey now i see the real thing.. i have all time a have like to say and point to real way of tpu
HERE YOU TALKING ABOUT SAME TPU AS S.M <<s.m words ,,,, MY DIVICES IS NOT FREE ENERGY DIVICES BUT IS CONVERSION DIVICES >.
THIS IS VERY IMPORTANT WORDS OF S.M VIDEO CLIP WHIT 62VOLTS SMALL TPU
YOU ASK WAY IS THAT YES <<this is the real conversion theory you have talking about here <,
conversion is mena this<<YOU PUT ONE KIND INPUT ENERGY AND YOU HAVE ATHERE TYPE OUT ENRGY >.THAT IS CONVERSION DIVICE>.
IF YOU PUT ELKTRICAL INPUT ENRGY AND THEN YOU HAVE THE SAME ELKTRICAL ENERGY OUT <<THAT IS NOT CONVERSION DIVICES>>
YES INNOVATION YOU HAVE FOUND ONE REASON FOR MAKE TPU HO WHILL WORK
I HAVE TOLD HERE 2 WEEKS AGO FOR TRAING TO EXPLANE WHAT IS MEAN THIS SIMPLE WORDS OF S.M WHEN IS SAY HIS DIVICE CONVERSION DIVICE THIS IS THE VERY IMPORTANT BUT HE SAID JUST LIKE THAT ,LIKE SIMPLE WORDS
BUT IF YOU BACK AND READ AGAIN AND LISTEN WHAT IS SAYING YOU WHILL SEE THAT WORD <<CONVERSION >>IS MEAN CONVERSION IS LIKE YOU PUT LIKE PUT SOUND GENERATOR AND THAT IS, INPUT ENERGY AND YOU HAVE ATHERE TYPE OUT ENERGY <<THAT IS CONVERSION DIVICE >.YOU TALKING ABOUT >
THAT IS ONE STEP SURE TO MAKE TPU REAL
YES there is resonace and vibration and and i whill now stop explane
KEEP GOING YOU HAVE SAID HERE WHERE IMPORTANT THINGS
I ALMOST FORGET <<<THE SMALL TPU WHIT 62 VOLTS IS MADE OF PLASTICS MATERIAL
ASK YOUR SELF WAY THE MAGNET FILD IS NOT HAVE POSIBEL TO MOVE IN TO THE PLASTICS MATERIAL AND YOU SEE THAT WAY IS PLASTICS ANDD SEE THE TPUs IS NO T HAVE MORE <kg> what is hapend if is plastics how to transmit elktromagnet fild like this
but is not elktromagnet fild there is ather

No, you are telling me it doesn't work and trying to put foreign words into my mouth. And after I learned how you performed the measurement I am not wondering at all. If you don't know that how to calculate induced current on an inductive load that is not my fault and the minimum I would expect is some respect, maybe some questions in an acceptable way and not to try set OTHERS as a fool if you make mistake.
Why would I tell you it doesn't work, when it generates high voltage at high current on my workbench? Why are you judging an experiment that you don't even know that how exactly has been performed?
My request would be to you to show as much respect to others as much you are expecting from them.

Probably you measured nothing. You'll never measure a ns spike amperage this way. (by your "cheap meter") But you can calculate the induced current since you know the resistance/wattage of your light bulb and the voltage of your spikes.
dude im telling you all to try this lil test
did not mean to offend you
there 2 engeryies at play here
the engery you put in and the engery that is returned upon disruption
it is posobile that my digital meter was affected by the emp ..... but do tell me why my transformer sings under load??
ist
so i changed my reed and my ist neo zap vibrating spark gap ;D :P to just a plain vibrating spark gap it all works well
i have used reeds in this lil setup but they get to hot and burn out i used the ist neo zap it spits radition so back to the good old plain steel spark gap
seams to be safest but let me tell you the neos are verry impressive not just the plasma flame i get but the electrical out put too ;D
for my vibrating steel or neo gap i use a fish tank air pump!!!! in fact it works well with the reeds too ;D sure there are better ways but this was easy and it uses 4w but that is no concern at this time the point is it is ac and vibrating and i can adjust it easly

I've did "impact test" with a another piece of iron (can't measure its weight right now, but it's probably 6-8 kg).
Response is much more complex, of course, since this piece of metal has a complex concave form.
However, frequencies present in the previous test are also among frequencies of this test.
They are:
2.140kHz (minor), 5.480kHz, 6.940kHz (minor), 11.5kHz - very close to already mentioned frequencies if you consider octave resolution. Highest harmonic this time is 7.290 kHz.
Attached is an image of both iron pieces. Small bar is what I used to strike iron.
