@K4zep . Man I take my hat off to you . You are , in the nicest possible way , like a dog with a bone . Techniques have been discussed on these threads to match resonant frequencies of coils . My suggestion was to build each coil in turn into a simple Radio Frequency oscillator , and check the frequency on a radio receiver or frequency counter . But you have scope and no doubt will use your own methods . The actual frequency is not vital so long as it is the same for all coils . Check all coils and pick the one with the highest frequency .remove turns from the other coils untill they come up to frequency . I just KNOW you are going to crack this , Keep on trucking .

Hi Neptune, NP,

Yes, many different ways to tune/check things out.  So many variables and so many ways that losses enter into the device that it is a mess.  I use a scope and freq. Gen, but other simpler ways to do it.  I wish Romero would lets us in on his thoughts on AIR GAP and what he was looking for when he did this.  I keep messing around with it.  Picture below of unit running on a 12.55 VDC lead acid battery, 4.71 VDC Gen output, total of 17.26 the motor is seeing.  Scope shows the motor keying waveform.  Part of the process to chart the efficiency of Generator and best RPM.  Keep backing up and verifying data.   Did a major cleanup on the closet/shop this morning, was buried in it!  The smaller the shop, the more you have to clean to keep your head above water!

I continue.......

Ron -its not watts I reported, but it is ammeter "crowbarring" across those 5 coils hooked in series shoritng them all out and motor doesnt go up in draw while it most certainly would and did, if that AC cap in series was NOT on AC leg of FWBR.
that was all I was trying to show.

Doug, yes, I had read that on your list. What I was objecting to was bolt's misuse of this information.

The endless repetition of his OU claims with no corroborative evidence or replication examples is a dis-service to the list.

i'm very impressed, Ben - not only do you have to work in the 'World's Smallest Lab' but it looks to  me like you also have to work with the 'World's Smallest Muller Dynamo'

your system is not much bigger than your solder spool !!

i think you must have a much harder job than a lot of replicators because the tolerances are always more of an issue on physically smaller systems

it's to your credit that you've achieved 'so much with so little', to misquote someone famous who smoked big cigars

...must have been either Groucho Marx or his less-famous half-brother, Winston Churchill Marx

you didn't know about Winston?  the Marx family kept that one quiet

Ben has great ideas great looking machine looks great keep going and dont stop

Ron -its not watts I reported, but it is ammeter "crowbarring" across those 5 coils hooked in series shoritng them all out and motor doesnt go up in draw while it most certainly would and did, if that AC cap in series was NOT on AC leg of FWBR.
that was all I was trying to show.

AC leg series cap in place makes same voltage into cap, as no AC leg.
how fast cap fills up however is dependent on AC leg cap uf value.
27VDC is what you get into DC cap after rectifying if you want to know from those 5 coils in series.

WATTS would be DETERMINED by the resistive load that the cap dumps into wiht the "two stage" output circuit.....and WATTS would be MEASURED in the dump into the resistive load from the caps from this cap-discharge formula:

farads of cap / 2 multiplied by:
high voltage of cap before discharge squared
minus the lower voltage of cap after discharge squared
multiplied by rate of discharges per second

(Ronald from Germanys formula)

Generally, as you know if you get say 10 amps in meter with ammeter shortingout coils (voltage now near zero)

and then measure voltage, say 20V  from that coil into cap, with no resistance (maximum voltage)

to get a quick idea of what you are going to get with resistive loading, generarlly, your voltage will drop bu 1/2 and your current will drop by one half (depends on resistive load) so with 10A max and 20V max "plan" on 50watts

so if I get 500ma and 27V, then I can "plan" on having say250ma and 13V after a resistive load, so its really around 4 or 5 watts using measurements of "lump resistive" load or so to expect from that string of 5 out of phase  coils...(most probably not best way to do it having coils inseries outpu of phase  but I am looking into it is all)...so wtih all 9 coils say around 9W ouput approx from 4W or so jsut estiamating....this wi with all coils in sereis which is really stupid way to do it -and also no helper magnets...probalby lots more if I did it correct and rectify each coi individual...if Ishorted coils into cap lots lots more...

Of course the whole ball game with these rotating genrator is to not have the rotor slow when you take out power and if that doesnt happen this is all good eh and HOW much power/watts is being taken out is subject to different measurements eh...

also the lump resistive load way to meausre is way different than the cap discharge way in two stage process with rotating genrator, so whenever your rotor slows, and output in watts goes way down as you know.
If rotor doesnt slow, or even speeds up and draw goes down you also get way more output....so that (in my feeble opinon)  is why you should always do the cap discharge output, and cap is disonnected from source too,  type of two stage output circuit with these things, so that the event of hitting aload does not amp-up the motor or slow rotor....and only thing to worry about then is the filling of caps (thats why you want to SHORT caps full but that is other subject)

anyways there are going to be a few differnet ways to make these Muller-loopers I bet in about a month from now there will be some loopers happeiing and they wont be all the same method...Bolts way to tune with helper-magnet distance and AC cap sins series is very VALID and has already been validated in video too and does not slow rotor
and so is my way of shorting coils at peaks and using two stage output and so is romeros way too, although of everyone is not completely sure of yet what exaclty he did to get it to work.

Hi Konehaed & all:

Much appreciate your postings and results, I am also following Bolt's recommendation of using series non-polarized caps with shorted FWBR DC outputs to tune for max. input ac current. I have gotten around close to 200mA for the test coil when shorted but my series capacitance is something like 15 microFarads! Well, if I can get 8 coils to sum 1.6A that would be a great start

My question is the size of non-polarized capacitors with rated 250V voltages  are about 1.5" x 0.5" x 1" ! Can I series up 2 electrolytics with their common polarities connected (positive t positive) to effectively use it as a non polarized capacitor yet maintaining some kind of effective working voltages without a whole bank of parallel large polarized caps. in series? This is what old ham radio people used to do.

cheers

Hello everyone!

Today I finished my setup that I've been working all week. Using only one pair of driven coils I get around 16V but when I put a load, Lenz appears too. I haven't made the driving circuit yet and I use a reed for now. Tomorow I'll get the hall tranzistors. For now loocks good and the only thing remaning to do is to fine tuning. ( sorry for my english)
