Muller Dynamo

[4Tesla]

Hi Chris,

Where did you get the 1.5 inch bobbins?

Thanks!

Hi Jason:
Here is a list for my spec:

Magnets 19mm (N42) from magnets4less.com
Coil wire: litz (7 strand from surplussomething in Nebraska)
Coil winds: 500 turns
Coil resistance: 5-6 ohms
Coil inductance: 6.8mH
Coil size (bobbin): (~1.5"x1" ferrite length is 1.5")
Core: ferrite of some sort
Distance between rotor & top & bottom magnets: ~5mm
Standby (no load): DC 12V, 450mA 1430 RPM with 2 driver coils active

Hope that helps.

cheers
chrisC

Baroutologos you used to hang out on Romero's forum did you not? I dunno where that is now may have been taken down. But i am sure you are privy to more information from Romero's early testing and building then anyone else. Perhaps you should write up an article to collate all this information prior to THIS thread may explain if we missed anything. Was that forum archived? is there a link?

True. I used to "hung in there" and post almost all my experimental work. In fact Romero was the guy (moderator also) that provided concepts and ideas for experimentation and posted a lot of useful links and parts-specs-videos of his work for (all? ) to see and I

on the other hand, disgusted of the endless talking and talking and talking of the other forums, i was there, inspired sometimes and learning along the way from Romero few electrical tricks (since he is far ahead in experimentation, skill and hardware terms) and because i like building things with my hands and have an interest in achieving OU of course.

There i tried replicate and worked on various popular OU concepts, discuss our ideas and post photos and videos.
that site, the 95% of work volume was about Kapanadze style experimenting that Romero, according his videos and testimony had achieved considerable OU out of this (12-15w input some 300 w output with grounding systems). Romero on that part of technology assisted me in assembling many useful curcuits (eg substituting Kacher running a Tesla coil by an push-pull inverter type setup etc) and urged me for purchasing an o-scope (the most useful thing he has said) and few others as running a Kacher with a middle taped coil etc.
He said the downsize was the considerable Rf emitted out of this setup and generally anyone caught playing for prolonged time with kachers will understand what i mean :nausea symptoms, headaches etc

Then he shifted his attention to coil shorting techniques solid state and mechanical and the rest is well known. I have kept back-up only few last pages from forum, only regarding the Muller type of his posts and videos (last 3 pages of a general thread somehow thread) for commemorating reasons.
...

I remember when i was working on a solid state resonantor with coil shorting module, he was talking about mechanical setups (that i used to hate. changed view after last replication assembly) and the use of the helper magnet to diminish lenz's drag, whereas he boosted output and the use of washers on the magnets that he had observed increased efficiency. I had not discussed much this topic, since my mind was focused elsewhere.

Anyway, i do not further recall anything of value in order to tune the muller setup to an OU state.

Salutes,

ps: I could not stay out of the fun, and not try to replicate the effect

Hey Barout,

Any tips on getting that waveform ?


Is that at the AC side of bridge?

About romerouk strangely high voltage output : Let me repeat again that output SIZE ( not amount ) depends on the strength of the magnetic flux that crosses your gen coil wires at 90 degrees. Also depends on the number of turns.
However 21 watts on a thin wire will probably burn your coils ( practical feedback would be good )

conspiracy : Romero was using litz wire, he never mentioned how he connected the litz wires, maybe he used them ans "bifilar" winding ? Maybe he crossed their ends to create bucking coils ? Who said inside 1 gen coil you can have only 1 coil ? I seen videos where a guy was using 3 gen coils in 1 coil. 1 extracting I, one extracting V and the other one was boosting rotation speed.

RomeroUK never answered that question. Anyone wondered why not?
Anyone wondered why in the looped version RomeroUK did not used coil capacitors while he suggested this later?
