Hi Laurent,

you did not tell us how you start the whole thing rotating. The reed-switch is only closed if it approaches the magnet.
So did you spin it up manually or as Ron said by compressed air ?

So when the disc is started to accellerate ( regardless whatever methode you use ) to you have to continue to move it manually ?

I simply miss the description of the process.

Help, help help !!!!

Hi Laurent,

please see my short sketch I made.
If you have no scope then you have a problem because - as I understand your process - youl will have
pulsed mode and therefore any digimeter or even analogue-meter will not be of any help.

If you can measure with a scope-probe across R1 then this will give you the voltage-spike, the time the voltage is
switched on and the period betwenn each pulse. Then you will get the mean-value of current by voltage / R2 x puls-time / T ( see pic MeanV.jpg)

Let us assume you measure a 2 volt-pike and this spike is lasting 1 milli-sec ( 1exp-3) and the time between the each pulse is T = 5 milli-sec the you must calculate mean-value of current i :

i = 2 volt / 10 ( ohm) x 1 exp-3 /  5 exp-3 = 0.01 x 1exp-3 / 5 exp-3 = 0.02 Ampre .

Using the attached layout will recharge your battery directly. I would recommend that you will drive this circuit with a  rechargeable NiCd-Akku ( 4 in series = 4.8 Volt ) Then you can watch during days of runtime if the NiCd - Voltage increases or decreases.
Better diodes : fast switching diodes,but even a standard 1N4148 will do it for the small currents I assume to flow here. If one diode get too hot put two or three in parallell.

Kator01,

I have an idea. If you can see magnetic flux lines around inductor or compute them just about the time it collapses, then why not treating it like simple magnet ? That way by placing permanent magnet nearby with poles so placed that will support magnetic field of inductor just before collapse (like two magnets stacking N-S to each other forming stronger magnet). You will be able to couple magnetic field for collapse.
OF course that would probably limit ordinary square wave impulses but who knows if back emf spikes are most important. Rotary magnet configuration would solve that problem but isn't that what Bedini is doing ?

good  day all

thank's Nali2001 i tried your circuit and it works  i used  1N5408  + a cap 400v 4.7micro f + a small dc motor 3 volt nominal fited with a small prop (that is probably not the best matos but i made with what i had and i am not electronicor)

be sure that my set up  will not take off   but the prop spin pretty well. ( with the rotor spining at 1100 rpm the small prop spin1680 rpm)

notice that on this setup i wound a stronger UCC with 44 turns 0.5 mm copper wire and something bigger than the previous one

@Kator01

you are right i have to buy a scope to see what happens. I made an amps mesure with an ampclampmeter    it gave me around 0.3 amp but as the current is pulsed can i  thrust this mesurement ?

now i have to scale all this stuff       the work really begins  + working on the perepiteia
