Thanks, T.

I am excited too. Hope this the effect we are looking for.

I was trying it with a battery a minute ago, dunno what happened but the cap (think it was the cap) of my driving circuit blew up. Luckily not the one with the ringing coil. Better be hooking up one or two diodes when feeding back to the battery.

From what I've measured at DC converter output I am OU: 12V x 4Amps = 48 Watts. Not putting in more than 16-20 Watts max. But I will probably not be able to use all the output without destroying the resonance or rotor stopping completely.

Wonder if the induced spikes can be shorted at peak as Kone suggests. This could really lead to an enormous power increase.

well done
keep up the nice exploration!
Happy experimenting!!!

Hi Chanaladad

wow who knows what you are going to discover next  - great work -

I have question - at around 30 seconds into video, you point to the drive-coil that is powering the rotor, which is making the bird-noise, and then you say you have two coils that are working as generator coils, and then you point to the coil next to the drive coil, and the same drive coil...I assume this was just a mistake, as later on you show the coil with the probes on it being a generator coil...

so there is no electrical-connection (as in wires) between the singing drive coil and either of the two gernator coils? the only "connection" would be some sort of RF coupling from the spikes thorugh the ambient??
is this what you are thinking is happening? This is what it looks like...

Does the generator coil not make as much power into cap and load when the drive coil is not in the singing-resonance???

does the rpms change when drive coil is in resonance?

does the amps input to the drive coil go down when it is in resonance?

Are the two generator coils connected? 

Do they both fill the cap seperatley with FWBR on each??

I am trying to think of something to "debunk" what you see, since it seems so crazy, but cant think of anything!!
All I can think of is that bird noise is the bearing squeaking, but I am sure that is not it...

I wonder if you take out the backemf/recoil of that drive coil what it looks like in power going into a cap while its resonating and what it is compared to when drive coil is not resonating.

I will guess that sound you hear is the collapse of the coil at turn-off hitting the edge of the magnet and pushing it...or maybe hitting magnet dead-on squared up so the feilds smash into one another makeing the high ptich squeak (just guessing)

whats your rpms?
it doesnt seem very fast but must be the video-frames slowing it all down...

OU X 2 is very great - keep going and dont stop eh

Hey Chal

What size is that cap?  Seems large for how fast it got to 12v with a couple spins of the rotor.  ;]

Have you posted the details on that coil and the driver?

Good work.  ;]

One more thing.

Can you try to see if the driver coil sings if you just hold the rotor in the right position? Be interesting to see if it sings continuously and see what haps on thos other coils without the rotor spinning..  ;] Gotluc had a setup that oscillated, no rotor.

Just thought of it, if the hall sensor is near the drive coil, this may be the cause of the singing. Rotor mag turns on the hall, and the pulse from the drive coil turns off the hall, thus drive coil off, magnet on, repeat. oscillator.

Maybe this thing can go solid state.
