Working Magnetic Motor on you tube??

[Yadaraf]

I'm going to submit this to this forum, rather than FizzX, as I was originally intending - because it has the handy 'Attach' feature - and I want to show what some of my data looks like.

I'm really responding to RunningBare and TPUBruce on an experiment I did with Bruce's 2nd video - OCAL Magnet Motor Experiment 2.

I downloaded the audio portion of the file from the 2nd video (http://uk.youtube.com/watch?v=l2ycczuFEF8) using videoget (thanks for the heads-up on videoget, RunningBare!).  Then, I turned the mp3 into a wav and brought it up in my sound editing software (SAWPro). 

......

Blue_Energy,

Could you post your wav file?  Thanks. 

Cheers,

Yada..

The wave is too big, Yada (over 13mb).  If you can convert it yourself, I would be happy to post the original mp3 though.  Just let me know.

Originals are always better anyway, Blue. If you can attach the MP3 ... go for it.  I can work it just as well.  Thanks.

I just got the analyzer working on my primary PC - a new laptop really -- and I'm calibrating it as we speak.  (FYI, I live in California -- GMT-8.)

Cheers, 

Yada ..

Okay - here you go!  Good luck!

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 !

RE:  Spectrum analysis of Al's first video

It took a while to process Al's first video.  Somehow I managed .. even while the Super Bowl was playing.  Good game.

I sampled Al's video three times at two different places, for a total of six samples as shown in the figure below.   Three analyses were performed for self-sustaining rotation at 1700 rpm [three rotating stators].  Another three at 4700 rpm -- after acceleration [one rotating stator].  I've included some basic observations in the figure below.  Al's voice-over didn't make this easy.  All inferences are welcome. 

Next stop: analyzing Bruce's soundtrack.

Cheers, 

Yada..

@Yadaraf,

Thanks for the spectral analysis. So, the characteristic frequencies in my first wave are 63Hz and 2kHz while here they are at 180Hz and 1.6kHz. I wonder if you checked the other files I submitted here just to see if the data are reproducible. Waiting to see what Bruce's data will yield.

On another note, was anyone able to open @korkscrew's applet: http://home.earthlink.net/~danniee/whipmag/WMModel.htm?

EDIT: OK, I got it. It only opens in IE, Firefox isn't its friend.
