Regards,
RomeroUK

I had only a 5w bulb as with the 20w bulb the dc converter gets hot after some time.
I tried to add the bulb before the dc convertor but there is more than 12 volts and the bulb will not last.
This DC converter is max 3amp but I am very happy about it plus the price was very low. Nice device and I think that all people should have one, it helps a lot in any other builds where people are trying self looping.I has even load protection and thermal protection too.I have tried for a second a 50w bulb as load and it switched off imediately.

Got one just like that DC-DC conveter in a garage sale for 50 cents

Hope all is well with the family and wife. 'Tis Saturday so you officially need to take the rest of the day off and get lots of rest. We'll all still be here tomorrow

Thanks again for all you are contributing here!

@groundloop and our other EE wizzkids

I can't remember if this has been mentioned before

I have been searching around for the Hall effect sensors and have found the A3144uea has been discontinued.

One of the manufacturers suggests the A1120EUA-T as an alternative

http://uk.rs-online.com/web/search/searchBrowseAction.html?method=searchProducts&searchTerm=A1120EUA-T&x=20&y=6

would you agree this is what we need?

I was seeing some A3144 Hall sensors on eBay from Chinese sellers. They usually ship world wide and good prices too. Not sure on the quality.

7 X 0.125MM SOLDERABLE STRAND EN.Cu 500g

If the wire comes in 500g rolls anybody know how much we would need to make all the coils in the motor?
any ideas Please?

I believe I read somewhere Romerouk used 2 kg. of that wire so I guess 4 rolls of the 500 gram wire.

You are likely going to hear about it and what will be said in the coming days or hours or weeks who knows they will talk about the following things.

The fact that the table is plastic and has nice big hollow legs.

And the fact that you have a 12v lithium drill with a 1/8" drill bit under your table at 17:18 on this video... Sitting right next to them big hollow legs of that table.

I think yes the best test would be for you to do a suspension test I can see all of the shit slinging trolls coming out of the closet here soon might as well put them to rest as soon as possible imho . Seems it always happens even when people are not conclusively I believe proved wrong something just dies out because of the replication process being a bit more advanced then most have the time money or mental capacity to complete a strong proving series of there own ever since cold fusion it has been this way probably even long before this even Tesla with wardencliff ... He was made a mockery and we first finally now start to acknowledge his achievements in the time of "peak oil" which is another false term imho that I would prefer to believe there is no peak yet I believe with all the shale and other things oil abundance could still keep us rolling for over a century at our current rate of growth but with everything getting greener I estimate it would even last much longer.

Congratulations RomeroUK,

I'm very pleased with your success in looping the output back to the input and demonstrating a self-running Over Unity device, and even lighting a 12 V light bulb, as well as demonstrating different motor speed operations by changing the voltage output on the DC/DC converter. I watched the videos and I'm so impressed, good for you. I'll try to replicate as soon as I can.

If this is replicated by a couple credible people I have some huge neos with 130lb pull force and some nice thick copper wire and would possibly be willing to scale this thing up. To see what kind of power we can really kick out of this thing but I will be waiting for a couple small scale confirmations before I waste my Wind Turbine stuff on this.

I would like to thank Muller for his design.
RomeroUK for his hard work and the open sourcing of a possible OU device.
The replicators in advance for possible verification of the said OU device.

All in advance.

Hi all,

Where can buy litz wire (7 X 0.125MM SOLDERABLE STRAND) in Canada or usa

chrisC · « **Reply #309 on:** May 08, 2011, 04:50:19 AM »

Ready made circular plastics for stators or rotor - Tab Plastics make a series of circular acrylic plates of varying diameters and thickness. Saves a bunch of time!

Yes first there is an odd number of coils to magnets this helps prevent no load cogging as each field is overlapped. But under load it begins to bog down again UNLESS the cores are Re-gauged. By adding another magnet to the back side of each coil the coil once pulsed becomes latched in north or south pole state. Lets say the coil is latching South it approaches a South facing magnet and tries to repel against the coil. Normally the greater the current from the last magnet pass the greater the latching as it approaches a new magnet so the lugging increases. The Re-gauging RESETS the coil by forcing back the flux in the opposite direction but it actually over shoots! This creates a north biased coil attracted fast to a south pole magnet and provides free acceleration energy into the system.

The solid state version of this is called ....wait for it = MAGNACOASTER. This is why magnacoaster has 5 neos one end and one the other with a measured tuned GAP. Yes its OU.

More abrupt the process is Bloch wall modulation where the return or re-gauging bias is an over shoot of energy from the back end magnet.

@bolt,

this is (I think) the second time I read something from you and I must say: It is very logic what you are saying and brilliant observation and conclusions of yours. The overshooting of the magnetic field, "viscosity", seems to really explain what we are seeing here. I think another guy in this forum was talking about this to be the key also for the mystery of Orbo device.

I had to read your post really slow a few times in slow motion to "see" the phenomena you explained. Just like waves in a pond, just a bit late and the magnetic field "forces" the ferrite core to retard the instantaneous reaction it would have into a profitable event where it attracts the next magnet, therefore, re-gauging.

Brilliant and it took a brilliant experimentalist to make it happen into a real device (really thank you Romero).

Today I purchased the neo-magnets, 13/16" x 3/8" N42 (about 25 of those), plus a 12mm shaft and its mounted flanged bearings. Also I ordered 2 of 20" x 20" plexiglass sheet and MDF for the disk. Dying to have it delivered to start building.

Fausto.

I'm taking all this information in as fast as I can and I have a few suggestions for RomeroUK.

1) make sure you document everything, it's very important.
2) continue to explore why you got the results you did and what are the critical factors, we need to determine the fundamental principle so we can duplicate easily and also scale up the design.

It sounds like the Muller arrangement of having one more coil on the stator than magnets on the rotor, i.e. 8 to 9 ratio, is a primary factor of importance, along with the fact that magnets are biasing the ferrite cores. The biasing is critical in eliminating the hysteresis losses, and the motor pulsing arrangement is another very low loss mechanism, so I second what bolt was saying, don't build some cheap setup, go for perfection and eliminate as many losses as possible.

An interesting observation I made is that the ferrite is biased and the rotor magnets are in opposition. This means the B-H curve is traversed from high H values to low H values and then back, as a magnet on the rotor approaches a stator coil, passes under it, and then departs away. I think this cycling of the B-H curve from high-to-low and then back is very significant! Romero, you might want to experiment and reverse all the polarities of the magnets only on the stators, and see if it still works.

just finished the rotor stage PVC disc with 8 Magnet Neodymium Disc N45 Rare Earth 22mm x 10mm fitted and center bearing.
I have two projects on the go today. I am still modifying My Adams motor to incorporate as many of the Muller Dynamo Techniques as I can.
I am interested in some of the electrical fundamentals. I want to test theses while I complete my replication.

We have bad experience with MAGNACOASTER. My friend made money transfer 2 years ago and ordered device, but still not have it. And no money back. No answers to telephone calls, etc.

romerouk and Hello everybody:

Because my English is not good, A lot of content can only guess, On the multi-strand wire:

1) a recommended 0.8mm multistrand,
2) Another way of saying they recommended 7x0.125mm litz wire,

But: accurate mapping from the actual point of view, 7x0.125mm litz wire of the total cross section diameter of 0.375mm, And 0.8mm diameter cross section a lot of difference.
I understand wrong? What is correct?

PS: multi-strand wire in the end is the option of using multi-strand bare copper wire? or choose to use multiple Enameled wire?

Thanks for helping
