Romero posted a new video. This is very, very identical to what my singing driver coils waveform looks like:

Hi all,
    Sorry, din't mean to distract everybody here, and thanks konehead for reminding me those post, haven't read that.
Back to work....

Hi Khwartz
the circuit of mine you chose to modify doesnt pulse a coil like a  motor coil pulsing cirucit would do, it is a coil-shorting circuit, made for generator coils induced by magnets sweeping by the generator coil, the generator coil never disconnects.....

Thanks to tell me that, I clearely see this different now

Quotethe FWBR in it, collects power into a cap "continuoulsy" and then when those mosfets trigger ON, it then shorts the coil leads together which increases the voltage feeding the cap.....

Sorry, I think I see the MOSETs can fill the cap, but I don't see on the orginal schematic, how they can short the coils :/ i can only see the blue circuit coming from the coil to the FWBR feeding, or not feeding the cap if the MOSETs circuit in "open", but I can't see how the coil(s) is/are shorted if the blue circuit open as I don't see any return path :/

Quotethe circuit you chose to modify does not connect or disconnect the coil to a battery or power supply then, like a pulsed motor coil circuit would do...

Do you mean that when the MOSFET circuit is closed, it fills the cap, but when it is opened, there is a kind of time that made hight voltage in the coils using bacEFM, and when we get it we close again the circuit to feed the cap with this higher voltage?

Hi Khwartz
"Backing magnets" mean there are magnets stuck to the backside of the cores, like what Romero did...these magnets dont rotate lile the rotor magnets, they are on the backs of the cores of the coils, stationary...

Yes, you're true, I remember having seen them

QuoteI dont know if that formula you have  will work or not.
the formula for cap discharge converted to watts is:
FARAD value of capacitor being discharged  / 2
X
(volts in cap before discharge SQUARED minus the volts in cap after discharge SQUARED)
X
discharge events per second  = WATTS

Hehe, it is the one have used, but to complete the calculation, I need to know the frequency of the cycle charge/discharge of the capacitor while connected to a load, and from which voltage he start to fill to which one he stops. (Frequency <=> "discharge events per second ").

Hi Khwartz
that cap discharge formula works pretty much perfect - try it out, use scope to make sure you get the voltages in cap right...
that coil-shorting circuit works first by the FWBR converting the AC induced by the rotor magnet sweep into DC and into cap...jsut a very nomal way to take out power from a genrator coil....
when that coil-shorting circuit turns ON (closes) it connects  the two leads of the coil together very quick and it collapses the coil and it starts an oscillation (ringing) and this fills up cap much quicker and much higher in volts....all the while the FWBR and cap are still connected as is "normal"
"musts" with this circuit are a very short pulse width to the coil-short event,  so that the coil short doesnt make for extra draw to the motor....  the coil short msut be happening at sinewave peak..... and also "collector" cap that fills up discharges to load while at same time the cap is disconnected from the "source" (the coil) that filled it up in first place...("two stage" output circuit)
