My be a silly question, but I have to ask.

In the replication description pdf http://www.overunity.com/index.php?action=downloads;sa=downfile&id=471, it  states at page 2 that the rotor thickens is 12 mm and the magnets are 10 mm thick. But on page 11 in the same pdf, the pictures shows that the magnets protrudes from the rotor.

Is this an error in the pdf?
Must be 12mm magnets and the rotor 10 mm?

what about woopy being silent, he had an almost colmpelte rig and now he is also gone ? Most of the people who were capable of building such a device went silent since a while. Maybe it's just the incomming summer.
Joulseeker, i'm really excited about sucha simple circuit of yours. Will try to visit a hardware store to see what i can do to confirm or not your results. Have really small practical knowledge, but that is why i'm here ( failed physics class 3 years in a row xD )

Actually, I'm concerned also about Penno64, he was like "guys, it's bigger than you think, need to do more measurements", and then he vanished... Hope it's to do a massive disclosure, as some guys planned to do that one point... hope they are all well

Well this not good news.  Woopy, where are ya?

Penno too. 

Ive seen where some dont post for a while and I wonder. But they come back.  Hopefully this is the case.

What can we do though?  Maybe when it is a sensitive project, most should agree to at least post something at least every couple days, or something.

Any ideas?

Hi Tudi

I am somehow silent because i am trying hard to get what Romero showed us in his video.

But so far i am sitting in front of the machine trying every possibility, tuning the biasing magnets,  the spacing, the Hall sensor etc..

It is a long work, because you have to bolt than debolt to fine tune, and as the system is wired between the top and bottom stator, sometime you really get nervous.

I also reread all the post of romero and of course review the 3 video to detect some details i could missed.

I have also made a template with the sine wave distribution all arround the track to see how the electrical path is working.

I am always puuzzled by the circular paralleled wired FWBR. I don't like how it works.

Now i have suppressed the DC motor as a load and i use a variable resistor (4 watts) and no capacitor, so i can see and regulate much finer the output power.

I also tried to spin the rotor with the central DC motor .

As you can see this device is really immensely tunable. But no OU at all until now. My best result is about 35 % efficiency. Very poor in comparison with Romero . And my machine works mecanically really well.

So i think i have to think really out of the box to find the trick, because in a conventionnal thinking i don't see how to traverse the wall.

Just for info i did not receive my Litz (they are comming from England probably by swimming and than by walking arrghhh)

Perhaps the solution is effectively in the litz ?

But i go on the testing i learn so much

Yes if Penno 64 or Lasersaber could perhaps say where they are in there testing. And Clanzer will probably very soon be ready. And also Zerofossil and Lidmotor etc

OK now back to the bench and tune

Good luck at all

Hi all,

i just put together a small rig (don't laugh    , its the principle that counts) to do some measurements on the coils of the muller/romero MG.
I have a rotor (cd) with 8 small neo's facing north up triggered by a hall (SS411A).
Both driver coils are made of the "brother sewing bobbins" (11.3mm high) with ferrite core (6mm od, 15mm long) from a PC PS.
Wire is single stranded AWG24 (0.5mm) about 220 turns which gives me 1.27mH/1.7Ohm

RPM is about 1500, and fiddling with magnets on top of the ferrite core gives only negative results.
When using a ferrite bar on top of the drive coil cores, gives me more RPM, and less input current.

I made another coil, now i removed the bobbin flanges, and glued them directly on the 15mm long ferrite core, giving me more room for winding, and also the first windings are more closer to the core.
It has the same awg24, and i was able to put on 300 turns.
This resulted into 2.81mH/2.5Ohm.

When i use this coil as a generator coil (by hand for now), and putting again the ferrite bar on top of it, the generated voltage increases.

So what i want to point out is that not only experimenting with magnets will get results, but you might also try to play with extra ferrite onto the cores.
It could be that this is caused by my small magnets compared to the coils, so anyone scaling up the coils could give it a try.
