@Yadaraf,

So, you took only that portion of my wave where the resonance is occurring and left the rest out, correct? Maybe you can take the initial portions of the other waves I posted here because they are at around 400rpm to see if there would be anything similar to @alsetalokin's characteristic frequencies. Too bad the rotor isn't with me (will be back from the machine shop on Tuesday, I hope) so that I can record it at 425rpm to see if the fingerprints will be the same as in the original.

Also, Bruce has a resonance portion in his wave. Would be interesting to see if it coincides with mine and how it differs from other sections without resonance (say around 425rpm as in the original).

Omni,

You are correct regarding how I sampled your last soundtrack.  I focused on the increasing "noise" that you heard around 230 rpm.  The figure that I attached shows the octave bars as well as "peak" indicators for the bars.  The peaks indicate where the noise was loudest.

If you'd be so kind to post your "400 RPM" wave files for me, I'd be delighted to analyze them like the others.  I live in California, which is GMT-8.

Cheers, 

Yada..

@Yadaraf,

I posted them here: http://www.overunity.com/index.php/topic,3871.msg75008.html#msg75008.

Unfortunately, the stators themselves (not the N42's on top of them) are somewhat secured to avoid the wiggle when not held by hand. When I get my rotor back from the machine shop on Tuesday (hopefully) I'll record proper waves with stators turning as required.

OK good people...

I've just run a couple of Waves processors on the important part of the original video - generally to remove most of the multiband buzz and lift the detail a little. It's only a hi-res MP3 to limit file size from the processed WAV.

Maybe someone has got a little more time that myself to play around with it further, though hopefully will help to serve as a point of general reference. Must get some shut-eye now - work tomorrow and it's 2:25am over here !

That was a heroic effort, FunkyJive!  I was hoping to use the resulting wav to do the same peak measuring thing I did with Bruce's.  But - it was scrambled too much.  It's too hard for me to tell where the peaks are - too hard to identify the sine within the complex wave.  Thanks for your effort anyway!

If anyone is interested, I took a stab at removing the noise from Als original video's audio as well.  I was fortunate in that there's over a half a second right at the beginning that's pure noise.  So - all of the humming noise is gone from my output now (good ol' Cool Edit Pro '96).  But, like FJ's - what's left has a slightly 'flanged' sound.  Also, even with that - I can't identify any rhythmic signature that I could use to judge when the rotor sped up.  The resulting file is over 4MB - so I can't post it here.  But, if someone can think of a use for it and wants it bad enough to arrange somewhere for me to ftp it to - I'd do that.

I've looked closely at sound files from three different Whipmag rigs now.  I'm really surprised at how smooth Al's is by comparison to the other two.  Is it his rotor bearings?  There's no 'beating' or clatter in the entire soundtrack.  It definitely goes up in pitch though, by the way.

Just been looking at @Al's wave file focusing on the moment of latching.ie just before Al says "there it goes". I amplified the wave and heard what I can only describe as a squeak at the moment of latching. I have not been through the whole sound track carefully but after amplifying the whole file the only point I hear this squeak is at the moment of latching.

Speculation: The rotor or the stator axial  is pushed hard against the bearing that for a moment metal rubs against metal.

Omni,

See attached figures.  Looks like you have something happening around 80 Hz and 300 Hz

Edit:  Analyses were performed on data sampled within the first few seconds of the audio recordings.

@Yadaraf,

Thanks again for the spectral analysis. When the rotor arrives I'll take proper waves and will post them for analysis. As of now the 1.6kHz frequency seen in @alsetalokin's is missing in my wave at ~400rpm which is outside of my resonance region but within the region where the effect is exhibited in the original. The lower frequencies in my wave also differ from the original although they are of the same order of magnitude as the original. It's interesting to see what Bruce's wave will show.

@Omni, Bruce

You are most welcome, Omni. 

Bruce, your audio was very clean -- best yet -- except for some apparent line noise.

I just analyzed the audio in Bruce's 2nd video and oddly [or not] his device also has modes at 63 Hz and 300 Hz (similar to Omni's).  Looks like 63 Hz is line noise in audio source, however, since it appears prominently in the baseline.

For anyone considering these analyses services, please leave a baseline [i.e. no talk, no spinning in your audio].  Also please provide at least 5 seconds of "clean" audio at the RPM to be studied.  Thanks.  Yadaraf Reference Labs, Inc.

@Yadaraf,

That 63Hz was present in the resonance section of my wave and was absent in the section at ~400rpm (outside of the resonance region). Is Bruce's 63Hz also within the resonance area or outside of it? Also, in my resonance part there was a 2kHz peak which is absent in Bruce's wave, correct (@alsetalokin's has 1.6kHz at ~400rpm while mine doesn't show any in the kHz range at ~400rpm)?

Hello All to all replicators

Messing tonight and came across another effect. Double to Triple GW rotation.
Ok... Start your rotor with a gentle spin, say 100 to 125 rpm. Note that all the Stator's all doing GW rotation. Now select a stator and flip in the GW rotation. When it catches it will spin at twice to three time(?) the rotation rate of the stators. Do not note any improvements, but still an interest effect.
So this device will allow both AGW and Double GW rotation.

Did a quick check and here's one data set
Rotor speed = 107 rpm ( this is all three stators spinning GW)
Stator speed = 585 rpm (approx)
DGW rotation = 1199 rpm

Give it a test, would be interesting to here what your devices do.

Regards
Bill

I still think that the counter rotating stator magnet was not exactly 120 degrees in alignment with the others.  It looks like it's out of alignment by about 10 degrees to the right in the video.  Maybe it's just an optical illusion, but since nothing else is working, why don't you fellows try moving the counter rotating stator magnet closer to one of the other stators, maybe 10-20 degrees down the circle. 

I drew a quick picture to show you what I mean.  I have a feeling that if it's going to work, it will work with this type of arrangement.  Someone atleast try this, or if you have already tried it, what happened?

Thanks,
Charlie

I'm doing some work on Phyllotaxis at the moment, it is intertwined with doubling 1,2,4,8,16... maybe if they are not placed at 120 the magic number might be 137.5 deg (to do with the golden ratio), creating spirals 21 and 34  clockwise and anticlockwise (adjacent fibonacci numbers. Could also be 34, 55 for example). The spirals produce values in groups of threes --that's another reason why this might be relevant: See Marko Rodin vortex math and family number groups 1,4,7 and 2,5,8 3,6,9.

Wishing luck to all you replicators, you might just change the world

@Omni

RE 63 Hz:  I believe it appears in all of your audio tracks thus far.  I've reanalyzed the first soundtrack you provided (see below).  Also, Al probably had a mode at 63 Hz, but the loud background hum obscurred it (in my sample but not FunkyJive's).

Here's what I think: 

...We should expect two characteristic frequencies (modes): one corresponding to the rotor bearings and the second corresponding to the stator bearings.

For the same RPM, two different bearing sets will produce different frequencies due to the size of the ball or cylinder in the bearing.  A ball/cylinder that has a smaller circumference will make more revolutions as the entire bearing rotates, and, thus, produce a higher frequency.  Follow?

Al's system had modes at 160 Hz and 900 Hz.  I'm guessing the lower mode corresponds to larger bearings (rotor?) and the higher mode corresponds to smaller bearings (stator?)

You had two modes as well, possibly:  one at 300 Hz and another at 1000 Hz (look closely at previous figures).  Again rotor vs stator

My hypothesis answers the following question. 

... Q:  Why did Bruce have only one mode at 300 Hz?


Lastly, it appears that you and Bruce are using the same rotor bearing.  Are you? 

It looks like Al's rotor bearing is much different.   


I'm going to bed.  Night. 

Cheers,

RE Al's rotor bearing

From the hypothesis in my previous post, I would suggest that Al's success might be related to his rotor bearing, which might have larger ball/cylinders that produce the 160 Hz mode.

If you're looking for something to replicate, consider shooting for 160 Hz on the rotor (at 425 RPM [rotor] as per Al's video).


Cheers, 

Yada..

 You will find a narrative on the Steorn Forum about the 7plus hours of operation of his device and why he shut it down.The date will be close to the beginning of this thread here at OU early last month.

No doubt you will find fault in it, but quite frankly I doubt that anyone here will care.

Folks here are responding to what they see and know, most replicators here are not fools and see value in his information.

AL provided us with information re his findings, and yes it would be wonderful if his information was complete but for many reasons it is not!

AL owes us nothing, he presented us with information at face value without claims beyond what he has demonstrated.

My question to you is beyond speculation or theory what facts do you present that contradict ALs information?

Because quite frankly alsetalokin made an agreement with overconfident to make this open source.
