Lumen,

What RPM range are you working in in your video?

[blue_energy]

Hello Blue,

Thanks for the Link.  It will be good for our European friends.  I need a U.S. supplier.  K&J do not carry N35's.

If you find another, post it up.  Thanks!

OK - here you go, Bruce.  It took getting extra serious with Google advanced search, but I found them for you.  These two pages are selling .25"x.5" N35 cylinder magnets.  That means that they will *apparently* be slightly shorter than Als, but exactly a quarter inch in diameter.  Plus, they're both shipping from the US:

The RPM is controlled by a tiny motor from a constant voltage source so it's not very accurate. I do know from my homopolar disk tests that it will spin up to about 11,000 RPM.
I never tried running this up that fast and never calculated how fast the magnets would be going at 11,000 RPM but the thought of one flying out and hitting the back of your hand or some other bony part (I can't even think eyes) would probably leave a mark!

I have a new IR tach coming and should be here Friday. (cause I do calculations all day at work so I try to avoid them at home)

It will keep the AGW lock down to about 200-300 RPM. As it spins faster the waveform reduces in size as expected but way less than I thought would be the case.
In the video I would guess about 800-1000 on the rotor but wait for the IR tachometer.

Hi guys,

I started checking this forum after I saw Al's video on youtube, and i've been following the progress of the replications this last week. Keep up the good work and good luck with your rep's!

I editted Al's video to slow motion and altered the zoom/contrast a bit, thought some people here might be interested to see.

I fixed up CLaNZeR last video [http://www.overunity.com/index.php/topic,3871.msg70590.html#msg70590] and put it up here.
[http://ou.whipmag.googlepages.com/]
I stabilized the video so it doesn't shake as much. Also tweaked the brightness. If anyone has a vid that people think everyone here should see, upload it here [http://www.sendspace.com/] and i'll mess around with it then put it up on the googlepage. If its a successful video, i'll put it up on youtube as well.

Henry Absolutly brilliant,

one can see the stators shift and stall.

going for another look!!!

How can one save?

@Lumen

Hey Lumen, I looked your video over.  Interesting idea but there's one part I couldn't grasp.  Now let me make sure I'm understanding your experiment.  You're using a coil based tachometer to produce a signal that your feeding into the scope.  You then use an optical tachometer to drive a transistor that shorts the coil/tach at a precise time, correct? 

If I've got all that right then the part I'm not sure about is the signal coming from the coil/tach.  The signal you're showing on the scope is the change in magnetic flux from the stator, not the stator's acceleration/deceleration.  Speed information is a mathematical function that needs to be processed/calculated from the output frequency and amplitude of the signal - when processed it would look more like steps on your oscilloscope, not sine waves.  The signal from the coil/tach in the video is definitely raw unprocessed data.  You should get the same data by placing any small coil near the stator as it spins.  Shorting the coil as the signal starts to increase means your allowing current to flow as the north pole of the stator approaches the tachometer coil.  This will put a load on the stator magnet and cause it to slow down - taking energy from the system, not increasing it as what appears to happen when you get a latch. 

The lower frequency oscillation you can see on the oscilloscope is most likely the rotation of the rotor.  Since the coil/tach is in close proximity to the rotor, it should see two changing magnetic fields.  A low frequency signal (rotor) mixed with a much higher frequency signal (stator) will produce the same modulation your scope sees.  What would be interesting to investigate is what the two signals are doing when you have a good latch like in Al's setup.  I bet they are some kind of harmonic (n), octave (2^n), or triple octave (3^n) of each other - maybe even a standing wave pattern.

If this is not a hoax, as it is appearing every day not to be, then I would say all you fellows working on this have stumbled upon the mechanism in which the universe uses to create energy.  I've theorized that energy is created when two fields, being spatially 90 degrees apart and of the same make up (i.e. both magnetic fields, or both electric fields, or etc), interact without any reactionary force.  I'm working on a project to prove this theory but my setup would not be something easily found in nature.  I've often wondered how the universe would do it, I think this motor (again if it's real) explains it quite nicely.  As a matter of fact, I would venture to say that the latch should occur when the counter-spinning stator's center point (the half way mark between north and south) is in alignment with the north or south pole of the rotor, and vice versa.  If this is the case, then you guys will need to bring the two other gear-spinning stators closer to the counter-spinning stator....  and make sure that the gear-spinners are facing south when the rotor magnet closest to the counter-spinning stator is facing north...  hehe it might improve your performance 

Off to bed,
Charlie

Thank's Henry,
1hr 5 min's to go. Dial up hope no phone calls  :'(

all the best Den

Doug continues to be delayed in his replica by some unfortunate developments that he's had to attend to.

Meanwhile, he has been making slow progress in his 1.5-scale replication.

I've posted some photos and such here:
