Hello everybody
 Is planning to replicate, but: do not understand how the coil structure to achieve the best results, please tell me in the picture below should choose "A"? Or "B" type?
 Thank you.

I’will do this Experimental again later.If succeed then I post Schematic,
and experimental's photos.

@nilrehob:

I am impressed, you did a great job with your videos, outstanding. Much has become clearer to me. And one sees again, there is hardly a thing on earth which has not been tried by some clever person before.

Below please sea a frame I grabbed from one of your videos (and I added two red dots). Is the reed switched triggered at both dots (positive and negative peak of the quasi sine wave)?

I do not understand a reed switch well enough. Does the south AND the north pole of a magnet trigger a reed switch? (With hall sensors it depends on the type of the sensor.)

For me, the last video (the one with the LED) shows gain when shorting the coil. And since you heard a clear difference in the noise made by your rotor when shorting, the rotor could slow down faster with the reed switch (more breaking force induced by the coil), which would explain where the additional energy came from.

Microcontroller: I was thinking about using one, may be the new MSP 430 LaunchPad (I got four of them) is good enough (up to 16 MHZ)

If i remember correctly the coils are not shorted in this particular part of the video.
When shorted you see very sharp spikes, or at least discontinuity in the waveform, sharp edges and such.

A reed-switch is mechanical and does not care about N or S.
By slow I mean the time between on and off,
the coils in my experiments are in my opinion shorted too long.
The actual switching is of course sharp as its mechanical.

16 MHz seems too slow to me, when i buy a kit it the cpu should run much faster

@all,

This guy is good - feast your eyes on this and try and replicate ->

p.s. note carefully the charger side and the resemblance to nrgfromthevacuum's free electricity
from a coil and cap circuit. Also the twin reeds !

@Romero, this should help us get a selfrunner!

Hi Romero,

Would you mind answering some questions.

1) What is the DC resistance of your generator coil (you mentioned it is fan motor coil from a microwave owen with its laminated core, right?) Normally such motor coils have some hundred Ohms copper resistance.
Do you happen to have an L meter to measure the inductance of this coil?

2) There is a yellow rectangular shape capacitor on this generator coil, I assume it is in parallel with the reed switch to reduce sparking?  If yes, then it eventually is in parallel with the gen coil, right? What is the capacitor value? 

3) Did you find any input drag increase when you tried to position the gen coil closer to the rotor magnets (to have bigger output voltage)?  [Here I am aware of the fact that once you fixed the reed switch onto the gen coil's side facing the rotor magnets, then if you place this coil closer or away from the rotor magnets then you unwantedly change the switch ON/OFF time too.]

4) Have you considered using a full wave bridge across the gen coil instead of the single diode? 

5) In the latest videos, did you have the recovery diode on the input battery side as you showed in your very first schematic in the first page of this thread?

Sorry for nagging you, I think these are important details...  ;)

Thanks,  Gyula
The coil resistance is 286 Ohms. My L meter is broken and I cannot give u more details about it.
The yellow capacitor is 0.47uf/275volts, connected in series with the reed switch.
Having the coil closer will slow down the speed of the rotor.
I don't see much difference if using a full wave rectifier.
In the latest videos I did't have the recovery diode connected to the battery.

I have tried a solid state switching but it is not working as the reed does.
I have discovered a new way to do the switching without the reed, it is with only one extra component that does the switching... it is amazing... I have to understand it a bit more then I will talk abut it more.
I am also working to get the same effect from a AC source, no more rotor and magnets, it looks good already.
My time is not allowing more testing today but maybe tommorow

@romerouk: I would say, use a 220 Volt 50 Hz AC source (secondary of a 1:1 transformer) and a spark gap that fires at about 200 Volt. But one could electrocute oneself easily with that. Please, do never do that.

So, it might be better to use a Joule Thief as an AC source. The secondary could be shorted with a spark gap to see whether that boosts the output or not. See the attached drawing. I did not try it yet, just thinking and planning. The CFL should become brighter with the spark gap (in case it works).

The depicted circuit oscillates at about 5 KHz and consumes about 200 mA at 1.5 Volt to light a 5 Watt CFL dimly (all without a spark gap).

Can this be done on a bedini motor shorting with a reed?
Thanks

Hi Guyla the best mentor ever !

Thanks so much for your always so precise questions which force us to go in our deepest thinking  and obliged us to face the real problem face to face.

And of course always ready to offer your best services in order to help.

I can say thanks a lot to you because i have learned so much from the biginning .
it is my tribute to you. and please go on this way ,

But of course

let's go on and
my last video

please be critical it is necessary

good luck at all

Hi Laurent very good work and video

I working on replicating your circuit design for coil shorting with mosfet you showed in the latest video.

I have to order some mosfets and I like to ask which is the most important parameter of mosfet for coil shorting circuit

Drain Source Resistance RDS on
or
Turn-On Delay Time td ON
or
Turn-Off Delay Time td OFF

to get best result.

and can you specify model of Hall Effect Sensor you used

Hello: romerouk and woopy
 
    Please excuse my English is not good, you can not quite understand the explanation in the video,
    Please tell me in your power coil in the middle of the video is filled with what object?
    It feels like generating coil at both ends of each one?
    Is ferrite?
 
    Thank you

That is the core a usual microwave fan come with . Laminated iron .
