Self running coil?

[gotoluc]

I think i can give an explanation for the raising voltage in the cap. 

The tuning with the magnet has to bring the core material *close to* saturation. That's the reason why the magnet must not be too strong, or too close to the core. If the magnet already saturates or over-saturates the core it doesn't work. The magnet drives the core into a non-linear state so that it acts like a rectifier.

Here are more details: http://www.linux-host.org/energy/srect.htm

The pulses going into the gate of the MOSFET are leaving the MOSFET on the other side as AC voltage, because of the gate capacitance. This AC voltage may be rectified by the 'magnetic rectifier' and will increase the cap voltage, if all the other losses are low enough.

Of course, this is no 'free energy'.
It's a well-known effect which was discovered more than 120 years ago...

Hi skywatcher,

I replied to your post about the toroid you wound here: http://www.overunity.com/index.php?topic=8892.msg233678#msg233678  and asked what color the cores were that you used.

Can you let me know please.

They have a gray coating.

Yesterday i made a core from a high-permeability material which is similar to Nanoperm or Metglass. With this core there was a considerable drop in inductance when i attached the magnet. With the N48 magnet it decreased by more than 99%. So i used a much smaller magnet. But also with this coil, i didn't get any remarkable effects. Not even a real resonance. The combined inductance without the magnet was about 400 mH (3 layers of wire).

I think i will not put any further effort into this topic.

Hi Mags,

Sorry but MarkSCoffman did not mean using the audio transformer to isolate the sig to the FET gate.   He proposed a possible impedance matching with the step down audio transformer to utilize the output power from the pick up coil in the best way for feeding the CMOS 555 with supply voltage.

rgds, Gyula

Exactly Gyula; as the voltage goes down in a 5:1 ratio the current will go up in the
inverse 1:5. The transformer is a power conserving impedance matching function.
A used 56K telephone modem card would have a suitable audio transformer.
Hi fidelity required for 56K. Hoping the transformer is 1:1 and the secondary
winding would have a center tap. There is even a way to use a 1:1 transformer
with no CT center tap to give 2:1 by making both windings into the primary.

The other thing to check is the CMOS NE555 timer chip...One may be able
to build a separate circuit for it where you set all the resistors to 10 times
their previous resistance and divide the capacitor by ten. It may not serve
as well as the commercial circuit board, but it might consume less net power.
You wouldn't want to effect final drive power through it though.

Finally, with a similar setup, the observed effect seems to be reproduced.

Input signal (Function generator model : GFG-8019G) @ 39.6 kHz - 8 vpp (square)
the circuit works on a 9v battery.
Adjustments and measurements made with an old 20Mhz Dual Trace Oscilloscope (ET & T 3132)
9.10v in the cap -> goto a maximum 12.10v (when disconnected) in a few seconds and stays there.

(a video is possible if necessary)

...under testing...

Excellent, if true. Please, don't repeat errors of the past, use the optoisolator method
to delete added function generator energy early. The asymmetric 4n35 opto signal may
work..It might even make things better. . If not, operate the signal generator at
2 x f and run the opto output through a cmos /2 FF flip-flop with circuit energy supply
coming from the bulk capacitor. Please keep us informed with what happens.

Also, what value bulk capacitor are you using?...that will affect energy to voltage
conversion speed.

Don't be too negative skywatcher. Maybe we are intergrating towards unity
gain but maybe we are integrating towards overunity. We have a line of what
looks like overunity and I don't think we should to dismiss it without checking.

Even if we eventually dismiss/accept where the overunity comes from it could
still make an intriguing glass bookend.   It'd drive people nuts!

                  Wrap a thin copper wire around a small section of the toroid. This will act as a flux blocker. Charging this tiny wrap by pulsing, will increase reluctance to saturation just in the tiny area beneath the wrap, blocking the flux path from the magnet to the rest of the toroid. Also, it would help to add a spacer between the magnet and the toroid material. Your dealing with a material of very high permeability, with a million times less reluctance then thin air.  Your first attempts have met with instant and overwhelming saturation. Try to get some control over this effect before you give up. Your magnets are way to strong and too close. Try wrapping a flux blocker coil in between the magnet and the toroid, decrease magnet strength and increase airgap. Try pulsing the blocker wrap at different frequencies pulse widths and power settings.

@Luc,

Could you give me a conclusion?  I need to confirm something... 

Could you remove [as in physically take it away] your pick-up coil for a while and tune your circuit is most optimal state.  Once you have that, place your Pick-up coil back again, but do *not* put a load on it.

If my thinking is correct, your circuit became now in an *de-tuned* state ! - Could you confirm that for me?

Also, you will [easily] be able to bring your circuit back in resonance again, by *lowering* your frequency slightly [I'm not to sure if it is lowering, but I think is it lowering]. - Could you confirm this is also true ?

Now when you place a load on the Pick-up coil [or short circuit it] you should *not* see any negative effects on your circuit as in cap de-charge, or de-tuning effects. - Could you confirm this is also true ? [***]

If you have an extra magnet laying around (such a small round one):  if you have your circuit is perfect tuned state, and you add [stack] the small magnet at the end of the others, your circuit will become *de-tuned* and you can re-tune it back again, by *increasing* the frequency a bit. - Can you confirm this is true ?

Ok, that is it :-)

Hi NextGen67,

here is the next video to test your above questions. Only your last question was not done in the video. I have tried adding a magnet on the opposite end of the toroid before and it has no benefit. Maybe we can look at this later if you want. Anyways, I think we should look at what I have for now to see if it's real before we try other things.

Setup is using signal generator and feeding 3 IRF640 connected in parallel

Tuned for maximum returned current -.000224 @ 38KHz  (with no pickup coil)
