Muller Dynamo

Not sure why you use "we". I personally only got to the part to buy magnets and wires . One of these days i will buy an osciloscope and build an efficient dynamo. Put it in a windturbine and get a few watts out of it. I value a lot what i read in this thread, lots of practical good advices. Keep on rolling.
I'm sorry you did not get rich by just reading the forums. Nobody handed you a ready to use device.

But that is what it started out as!!!  Only days later did it turn out that the "KEY" was missing.

I am willing to be included in the 'we'.  And neither of us are in it to get rich so your put down is just that.

I never thought I'd get to see the real machine again!

Nah - that's a fake - the real one's on a GARDEN table!!!

Stop following each other and the blind should not lead the blind.
There will be no help from RomeroUK. In fact anything he tells you must be treated with suspicion.
Ask yourself: this guy was scared shitless at some point and then he turned up here to help you again? How did he suddenly learn to become brave?
May be there are two Romeros, the coward one and a fake one.

Not saying that you are making the claim of 2 Romeros.
But he did confirm that the coils were bifi once I stated that it was the only way to increase the capacitance of the coils without adding caps. All this after the visit.
So I doubt an impersonator with an agenda would give that info.
Also, if it were an impersonator, I believe we would hear a lot more from him here, not so sparse. ;]

And then there is the latest pic shown of the coils with more than 3 leads. That is solid enough for me.  ;]

Romero rarely responded to my posts, probably because I stated a couple times about increasing the space between the rotor and coils to get rid of, or lower, lenz effect. But we did not know of the bifi. So I wasnt wrong in questioning him, I was just ignorant to some facts that nobody knew at the time, only Romero.  Im cool with that, but he just may not like me for my comments. I wasnt being mean or anything about it. Such is life.

Hey MT

looks good the driver and the hall are right...I  actually have seperate power supply for the driver and hall power supply and will use a 9v battery for that when first testing it, later on there is a small aircoil in the stator plates sandwiched between generator coils that is rectified goes into small cap and supplies the power for all the switching components...so anyways the .1uf AC cap and 4.7uf DC cap go across the driver, not "so much" the mosfet way over on right.
Also I like to use bidirectional-mosfets, where you hook two of them up via gate to gate and source to source, and then the swtiching occurs through the two drains that way.  Seems like much better backemf/reocil recovery that way.
Backemf/recoil recovery is done by simply putting AC legs of FWBR on each of drain lead of the two mosfets....at 12V input you will be having near 300V in small size cap in a few seconds. you cna use single diode for this too.
put this cap  into load when coils are disconnected from this cap (two stage output circuit) and it wont affect draw to motor at all.

One thing I cant understand is how Romero just seems to plop all the power rectified from the generator coils straight into that DC RUN cap, and it took off to high speed and rpms skyrocketed, then he went with the DC to DC convertor and it controlled the runaway and it self ran.
ALWAYS when I put power form generator coils into cap, then try to run it back into the motor coils "directly", it lugs motor UNLESS you make circuit where caps filled up by generator coils is DISCONNECTED FRON GENERATOR COILS WHENEVER THE CAPS HIT THE LOAD....(load being the motor coil switching and the motor coils)
Romero was saying there is "one more componnent"
How about a three-lead reed switch ! (or solid state equivalent) , this is common simple way to disconnect cap from "source" whenever cap hits load.

also this throws out the window, all the testing right now being done with the coils going directly into a load or continuous-shorted-condition, hoping to make a good speed up under load,
since in the "two stage" output circuit (cap disconnected form source when cap hits load) , all that the coils will EVER do is fill up a cap to the voltage you need to run the motor coils....
the genrator coils never see the resistive load, they only see the capacitor...
and the capacitor NEVER is connected to the coils and the load at same time.

Anyways I know with "coil-shorting" circuits, (shorting coils for just a blip at sinewave peaks) you MUST have this two-stage output circuit,
and also with backemf recoil recovery, you MUST disconnect the recovery-cap from the coils when it hits a load or else eveythign jsut backs up and whatever you take out makes more draw at input side...

But if cap is disconnected from coils you get a good GAIN and no "lenz lug" except for the filling of the capacitor in first place.
So first thing is  find minimum size cap that "keeps" your motor running.

Say for example, this "RUN" cap is being pulsed once per revolution from the battery or power supply - that is first step to do.....
then now you know this is the size cap you need to keep motor looped,....with me its a 2000uf DC cap (pulsed once a revolution of motor from 12V battery and I have 8 pulses per revolution of motor too) ,

probably to do a looper you will want to fill first another "collector" cap that gets up to around twice the voltage of the RUN cap itslef and dump it into the run cap (AKA cap "bucket brigade" method- dumping one cap into another)...

some people say this is "power loss" dumping one cap to another but compared to lenz-loss its not anything to worry about eh!...also its not really power loss its voltage-transfer with some loss being only the resistance of the caps is the only loss.....it cant be a power loss until the "end" since there is no resistance applied until the final RUN cap dumps into the motor coils and the motor coil swtiching.
what it is is that you want to isolate the power made from the gernator coils from the gernator coils themselves when they run the motor so there  is no "reflection" or step up in input draw.

And the "load" you want to be testing on your genrator coils is not a certain lump resisitve load, or a shorted condition, but rather your generator coils filling a cap up to twice the voltage of your run cap wihtin a certain amount of time (such as the time of one revoltuion of motor)
the run cap probably around 2000uf or so I bet on most of your rigs since mine is similar but half the size with only 4 rotor magnets
the "collector cap" should be a little more more uf vlaue than the run cap so for 2000uf run cap, then itts maybe 2200uf collector cap...jsut to cover losses of one cap into the other.
