I just finished making my rotor.  I easily made it using smooth-on products.  I have been using their stuff for years in my projects.  You all may want to check them out.  I have nothing to do with the company so this is not spam.

Here is a video showing the process:  http://www.smooth-on.com/video_play.php?video_id=iu7vpoIolJ8&autoplay=1

Interesting product.  Can you say about how much it cost to make the rotor for example?  Once it is dry does it tend to have a surface prone to static electricity like acrylic?  I'm still thinking the acrylic and similar plastics may play a role in how this works. 

Ah, about collecting parts, I also need quite a lot to buy, thats why I'm still hesitating for construction. Regarding the Litz wire, I will use this method posted http://www.overunity.com/index.php?topic=3842.msg284800#msg284800 because I got 2 kilometers 0.15mm insulated copper wire at home which I could combine to a 7-stranded wire.

Has anyone found a good U.S. source or maybe even China source for the size Litz wire Romero is using?  My experience ordering from U.K. is it takes longer than even China and is much more expensive than anywhere (especially with the dollar low now vs. Euro).

I have ordered some from here:  http://www.surplussales.com/wire-cable/LitzWire.html  I was going to wait and see what it looked like in person before I posted anything about it.  I spent $30.00 for two pounds.

Thanks lasersaber!  on both items.  I had not been aware of the smooth-on products.  Looks like it could be really useful for a number of projects but I think I'll wait to hear how yours goes with this.  I know you are one of the really good builders and I have confidence you can get this replicated with OU assuming the acrylic is not part of the OU formula.  Best of luck!

I have received some parts for the new build.

@Romero,

Thats great man. I ordered many things too. Magnets, wires, rods, ferrites, bearings and so on. Dying to have them here.

Now, in your opnion Romero, do you think that coils at high resitance as 150+ohm and 150+mH would not work? have you tried it?

The reason I ask is because readily available small coils are very cheap, precision made and small. For example relays from RadioShack in US.

Your input would be highly appreciated since all I am doing is trying to replicate your work.

Fausto.

No like rain cats and dogs there is coming differnent OUs   
Look at Hoppy´s TPU Replication  http://www.overunity.com/index.php?topic=10710.msg285458#new   

But OK, when Romero´s - Muller dynamo really works, then why to use rotor with magnets at all 

Just take two ferros core coils, set it up exact like one Romero´s unit with two coils and instead of moving magnet just use third ferros coil between these two coils - but this third is pulse driven,

NS->COIL->pulse-driven-coil->COIL->SN

Yes, this is very similar to well known units from other threads, but you must have all the same air gaps like Romero and top and bottom magnets - you must replicate all this like opened magnetic circuit, like Romero did.
Benefit of this experiment is you do not need so much different part. At that you will get solid state OU (if at all)
If it works - then you can be sure that Romero´s device works as well,
If it does not work - then ...    ... oh dear 

Why I do not try myself?
Because I have tried looooong time ago - no way 
I just looked Romero´s video and wonder why he is holding hes machine by hand, why not just by string or something like that?
What is behind holding hand, we do not see. Why there are so much wires? Like always - lot of wires, shabby imaging, failure cameraman ...
Was no time to make order, to short all wires for correct length? .... Come on, guys 
He did what he did --- few days like shooting star, but now is coming a thinking time, to think about results and ... about reputation 
But anyway I wish good success,
cheers,

Actually, there is quite a difference between your solid state version vs Romeros.
There are changing angles involved in Romeros setup, yours not, it is stationary.
Seems most dont get that the field lines need to pass through the windings to produce current, not just the core.

Think, how could a wire come in contact with the field if its all in the core. It cant. The wire does not have feelers around it to come in contact with the field in the core. Same as a transformer. An E core transformer has lines of force expanding from the center core and cut the other windings on the way to the outer part of the core.
Read he pdf attached.

I have seen a solid state version that seems it may imitate Romeros function. It had 2 driver coils off center to the pickup coil. I believe the driver coils alternated the fields produced on each side of the pickup.
This will enable the field lines to pass through the windings much better than an inline driver.

I will try arcylic as well if this first rotor fails to work.  I do not give up easly on anything.

@lasersaber
Tab Plastics sell several 5" to 14" ready made circular plates that can be used for stators and rotors for this replication. Check them out. It's less than $10.

Romero if you are still around just one question on what you used for spools or bobbins to wind your coils.  Were they sewing type bobbins?  I see some on ebay with these sizes: SIZE:    3/4 inches (20.5 mm) wide & 7/16 inches (11.5 mm) thick and  1/4 inches (6.4 mm) hole diameter.  Sound close?
