Hi all. Just a note on the DC2DC converter.
It was someone on this thread who told Romero to get the DC converter!!!
He didn't have it in his earlier tests...it was suggested to him by us!

I wish the latest events didn't happen.....but I think I will make a rep as well.
Another thing to note is that there is no real need for any driving coils. Any prime mover would do because the output is regulated, so i think builders should make the rotor/stators and  gen coils first and make some running tests. It will save lots of time.
All we need to do is tune the machine so that we get output under load without acting on the prime mover.
The tinkering will be in setting the coil spacing and the biasing magnets....a little sigh when thinking about that.  ;D
Cheers.
Scotty.

I wonder why Sterling Allen wasn't all over this one? Does anyone else find that weird?
Maybe Sterling Allen could see something we don't.

Its a clear as day the  battery lead is the coax supply from the DC inverter.  If you ever stripped back a laptop supply you see the same wire. Its SHIELDED coax because its a switching inverter and is RF noisy and there are inline chokes fitted near the inverter also.

Oh wait that might be an AA battery with some black tape around it...oh bugger.:)

PS make sure you find some nice cores otherwise this ain't going to work. Its the very reason Muller went in search of special black Amorphous sand. However in recent years high power Switching PSU's require very high permeability cores some are 100 or 1000 times better than standard ferrite so no need to go looking for black sand.
I was able to get amorphous metals,
And can be the size of the data produced by my heart
But I can not determine: the effect of amorphous metal is indeed beyond the ferrite.

@ Tudi,
that was an very fine analysis of the problems ... and give to think about this.. tks

@scotty.
This DC/DC Converter to use is fully NONSENSE and to complicated, also with minimus 10 % losts.

It give more and EASIER WAYs, to regulate the input and putput voltages, drive up and to hold the optimum of rotating speed.

Possibly: No inverters . no semiconductors needs

There is problem with getting cores, in Europe.
Those average Joe's ferrite rods that everyone offers are crap, they are not meant for high flux operation.
I'm not into combo-core from toroids also because hole in the middle would offer "parasitic" flux path.
I guess best option is try to localize I parts from EI or other core types that are made from proper material, for example Sendust.
If anyone has had success with getting proper stuff in Europe please tell.

Possible shapes in order of preference:
rod (at least 10mm diam, 20mm length)
block
plate (can be stacked to form a block)

Materials in order of preference:
- Sendust or other high saturation point,
low eddy loss material
- ferrite meant for power applications,
with low eddy loss

And again, tinkering with steel bolts and laminations is *pointless*. Seems it cannot be said enough times :)

STEEL BOLT IN AC APPLICATION = SHORTED EXTRA WINDING ON TRANSFORMER

Request for admins to really try to cut the crap on this thread.
Also everyone, please learn to reply without including whole original post...
We have extremely poor Signal To Noise ratio here :D

Hi folks, I fired up my setup with just the 5 coil/cores, only one driving coil in repulsion, just to see if it would spin up to a decent rpm.
At 12 volts it's probably around 500 rpm, though with using the reed switch, the pulse on time may be too long or the 24 gauge wire may be drawing too much amperage as the coil/core is getting rather hot.
Of course it could be the steel bolt, though I've had similar steel bolts run cold to the touch in other pulse motors.
So my guess is too much amps for this coil.
It was drawing 700 milliamps no load, and when I shorted one coil it only rose about 50 milliamps.
Anyway, this was just to see if it would even spin up properly.
Though of course, eventually I will get get ferrite cores or equivalent.
peace love light

Hi bolt
You talking: "make sure you find some nice cores otherwise this ain't going to work. Its the very reason Muller went in search of special black Amorphous sand. However in recent years high power Switching PSU's require very high permeability cores some are 100 or 1000 times better than standard ferrite so no need to go looking for black sand"

Here: amorphous alloy core
If the use of amorphous alloy core material, the effect can be completely beyond the ferrite does it?

Hi Romerouk:
   I was able to get amorphous alloys, But also in accordance with the requirements and the size of my production, If I use it to make the coil core, Will get better effect?
 
   The following are commonly used in magnetic parameters of comparison:

BTW Aedini did NOT get amorphous stuff, I explained it here:
http://www.overunity.com/index.php?topic=3842.msg285258#msg285258
Seems that chinese just have problem with terminology.

I just bought that DC converter from Maplin and opened. The circuit takes all space inside, leaves no room for a battery.If the circuit is removed will be removed with the voltage switch too as is soldered direct on the board. If there is a battery is not there.

Im not speaking about what Romero did, but there is many ways for "replicators",
For example with Supercapacitor 58.33 Farads with a maximum voltage of 15V and maximum energy storage of 5133 Joules at a cutoff voltage of 7.0V ... this allows the SC to power a hypothetical 5W load for 17.11 minutes or a 20W load for 4.28 minutes. When combined with power supply like the HESC104, HESC-SER, or HPSC104-SER, the result is a “no Battery” uninterrupted power supply (UPS) complete with 4A charger and power management features capable of supplying short term power to a system for a set period of time until a proper shutdown is completed and/or main power is restored.
Is it difficult to change the cover of CAP???
May be  ::)
cheers,

thanks Tudi, that was a very comprehensive and considered reply

maybe you have now started the 'ball rolling' (or the 'rotor turning'?) with the input of some theory into this thread?

to advance theory we need more facts

we've had so little actual performance data from Romero (just one unscaled scope shot of a single genr. coil response, and some meter shots) that it's very difficult to get a feel for the characteristics of the device, so far

i think this will change as people start to make progress with their builds and can feed back more comprehensive data

all the best

what is the size of such a cap ??

IT IS BIGGER than an battery  holding same capacity. .
it is sure that no things loke this, must be used fpr running over long time
(because less than 100% efficency)

Size is similar to this big cap on the video, as well as two bolt connectors on the top  ::)
Only coverage is different,

If this guy was for real, don't you think he would have posted the plans on a site like this before showing the entire world?

That's exactly what I would do too. I'd present my invention (if I had anything) on this website first, like many others because it's internationally one of the most well known pages for alternative energy. Good day, Mr. Troll.

I do not see any problem to use SUPERCAPs, even when low voltage, what are much cheaper, you can only speak that there are 300 turns and appr. 12V output, but in reality you have just 3V and you use step-up, switch-mode DC/DC converter. Now when you need to rebuild it for "small capacitors", you will buy really small size ones from sellers from China  ::) Why to spend a big money for goofy believers  8)
