Hi guys!

It's early morning here and i will be gone for 2 days.

Labas!

Keep it up and keep in mind about magnets as infinite energy source to harness. In my opinion, after balancing pull and push of forces you may overcome Lenz law and take energy out of oscillating magnetic current while feeding it back to mechanical rotation with very short electromagnetic pulses(see Bedini self running motor).

P.S> Shame for such negative statement from RomeoUK account, the Muller dynamo was already replicated by others and his statement makes no sense at all after all.. Keep replicating!

P.S.S> What happens when using dual winding on same cores while 1 coil is for generator and other is for driving? Did anyone tried in that way (including dual bifilar coils)?

hi Labas

Yes I have done that alot- using "bifilar" (two wires paralell) wound coils, and use one wire as "primary" and other as secondary - it works fine and this is actually way to collect the backemf spikes too, as the very tight induction of the two paralell wires throughout the whole coil, makes it so the secondary-side will pickup those backemf spikes if these coils are used as motor/drive coils, and so is another way to harness the backemf/recoil besides the "normal" steering-diode method.
what you do is pulse out the secondary into caps when the primary is OFF so as to not affect draw to the primary when you tap the secondary into caps...

Hey everyone-
Looks like the coil pulled back aways on the core is working good at speed up event under shorted or heavy load - already three guys have done it -

and just want to point out that RomeroUK did have his ferrite core's tip jutting out a bit from the coil, and also was using those plastic sewing bobbins to contain the coils, and so you could say that he had maybe a total of 6mm "recess" to the coil on the core as measured from tip of core facing the rotor magnets to the face of the coil...
and Marusivic was saying a ferrtie core didnt work in his experiments - but maybe ferrite would and did work for romeroUK because it happened to be his postioning of the coils on the cores,
in combination with the magnet behind core,
and in combination with arigap between the rotor magnet and core -  came out to be just right to get a speed up with the core-type and coils and magnets and rpms and airgap he happened to have found worked out right -

and if you times that speed up by the 14 genrator coils total with each producing a speed-up,
and the small volts and amps produced by one coil, and then this X 14,
and fact that when rotor does speed up you get even more volts and amps (for free) produced from the higher rpms,
and fact that when it keeps speeding up with nothing to stop it like lenz law and so just friction of bearings and wind resistance, it will go into runaway-mode; this also what romeorUK reported which was solved by the DC to DC convertor...so just thought I would point all that out in case somebody thinks romeroUK made it all up for some reason.

Hi all

Here is a jpg picture of the core design a guy in Norway did in his Muller-gernator (16 magnets and 15 coils each side driven by AC rotovertor motor) that looped itself, and he had leftover power to run TV and lights in mountain cabin (he eventually sold it to someone secret and he also got threatened a few times too but told them all to get screwed)

anways the core material is of very expensive hiperco 50 material, and in fact the the total cost of his cores in this single machine was around $3000 USD so it was cost-was-no-object project, and he did find the objective you could say.

Anways in this JPG, the needle-point faces the rotor magnets, and the coils dont wind around directly over that needle point, he had nylon spacer up there that the needl-point inserted into - I assume the nylon spacer was the same width as the backend of the coils so coils wound easy across.

This is interesting since it is similar to pulling back the coil from tip of core - as the core is going to be induced into its polarity more "heavily" towards back of coil as compared to the front (needle point end) of coil...

this guy didnt have magnets at back of cores as far as I know...

I dont want to give his name, since whoever or whomever threatened romeroUK a few months ago is still probably hanging around and reading this waiting for something else to happen that he or they think deserves another threat.

Hi JoeFR,

Here is your modified schematic where I omitted the SS Relays and drew MOSFETs instead.  Unfortunately, this time I drew one P channel MOSFET in series with the flyback diode, I know you asked for N channel due to the much better ON resistances but I can consider it only later. Perhaps this P channel type, using 3 or 4 of them in parallel could bring down the resultant channel resistance under 0.2 Ohm when they are ON:
http://uk.rs-online.com/web/p/mosfet/6504895/   I know this is only 200V drain source voltage rated, maybe a bit risky to use.

The NPN high voltage transistor could be this type:
http://uk.rs-online.com/web/p/general-purpose-transistor/6697587/ 

I show the n channel MOSFET switch of the load triggered by the charging voltage of the 680uF when it reaches near to 100V DC, the series connected Zener diodes start to conduct and the MOSFET switches on, you can control its ON time a little by the 22kOhm potmeter. IF you wish to control this switch also from the Arduino, then I will draw it also.

Regarding the ZD1 and ZD2, I indicated them to be 10V zeners but you can use 15V or even 18V types, because the higher gate-source voltage yields lower ON resistance.

I will try to come up with some better schematic where both MOSFETs are of N channel types...
