I don't think of "Near Strong / Far weak" as being exceptionally
problematic.

 See the attached file below

That is an excellent writeup Floor. I missed that somehow.
I have used variable levers so I have to see how that applies.

Please find below the attached   "Magnetic force shield repulsion" PDF file.

This is a design all ready presented on this topic ... but those drawings were as functioning
in a magnetic attraction mode.

Looks great Floor but how do you get the middle magnet pushed back in
so the cycle can be repeated? It could be easily inserted from the viewer
when both mags are matched rather than inserting from the end as the
drawing would suggest. And then how do you get the 3rd magnet on the right
to go back so it will repel because it is red to red and black to black..

Also remember closer stronger repel and further weaker repel so the
drawing is correct but that distance is likely not as realistic as it is to the eye.

I was grand parenting for a week and out of action so have to catch up.

Floor I did get your blocking magnets to work when I made it right and it does
slide in and out easily if the sliding magnet goes along the line of the joint between
the two magnets of opposite poles.

Now I need to measure the forces to move vs the output.

In the past I have had several OU devices but to do the feedback and switching
to make it self run it needs about 300% OU. I was never able to get more than
about 250% and Like you I used weights to get accurate measurements.

You sure have an eye for magnets.

Hi Norman

The blocking or "shielding" magnet  can be inserted and / or remove without doing work against magnetic forces.
This is because the attraction and repulsion are in balance, but that balance exists along certain lines of travel only.

When the shielding is in place...  the outer magnets are neutral to each other and also neutral to the shielding magnet,
but this absence of force / neutrality  is along a certain line of travel / directions only.

All magnets must be in precise alignment (centered and squared)
All motions must be at precise right angles.

Floor I am working on the measurements today. I use two neos in repel mode
about half an inch apart where it has a good bit of repel force. Then I use 2 Radio
Shack ceramic mags with  the hole in the center for the repel canceler.
It has some edge sticky spot problems and is very sensitive to get balanced
so it does not attract nor repel. It clearly looks like it takes less force to release the
repel than the repel force work would do.
Attached is a photo. I have a video of the edge sticky spot but I'll work on the
work out measurements now.

On the right you can see a red line which is where the 2 blocker magnets join
and you can see right below it one of the neos that is held in place by the metal.
On a separate setup I found that 3 washers can be lifted 1/4 inch from 1/2 inch to
3/4 inch. So if the work in is less than that it will be overunity.
Remember this is just rapid prototype and crude testing of the basic principle so
don't laugh at it.

My measurements are 150% out for 100 in. Which is OU but when you have to
reset the device to repeat the work multiplied it will not have enough extra to do
that which agrees with other OU devices that I have made. So unless the work in
or work out can be increased it will not self run.

But Floor you have worked diligently and found another permanent magnet OU
device.
Floor, with your skills I believe you can improve that to maybe 200 or 250%.
The problem is you need a small gap to get max repel work out.
And that takes precise embodiment.

I tweaked the balance today and got it up to 1.92 OU - in work = 1  out work = 1.92
and it takes less to move it back so there is a good bit of hope on this.

@Norman6538

High precision in alignment
         and
equality of the strength of the magnets used
       are critical to the functioning.

The shielding magnet needs to be roughly the field strength
equivalent of the fixed and output magnets combined.

         best wishes

Floor, yes I realize equal magnets are crucial but the ceramic shield
does work due to the distance and they are thinner than the domino mags.
I use 3/8 in neos which reach far but are smaller than the ceramics.
I had no square neos to use.
And since the reset takes less work it just might self run.

If that works then ganging them together would create some
significant work out.
As Archamedies said "Yaricka"  sp? but I had my clothes on when I said "Yaricka" .

Floor, what is your next step?
I will try some other magnets but I will not modify this device because
I have had working things that got disturbed and modified and never
worked as good again. Its called "the Bollinger lesson".
I have my original pendulum that goes up further than its dropped point
in a box so it can be observed as it worked.
See my attached principle drawing without the pivoting part.

Thanks Norman the drawings are appreciated.

There are many other drawings (hundreds) which illustrate
these principles. in the latter / second part of tjis topic


@ ALL READES

There are 19 short videos at this link, which show most of these action sets.
They are simple and yet what they imply is mind bloweing.

Unfortunately that site goes to facebook and my computer blocks facebook
because one time when I was changing my cellphone virgintmobile went to
facebook and I did not trust it. Most people don't watch where these web pages
go to but I do. And fortunately I do not have the fastest cable internet so I can see
them.

But you are right about the simplicity and implication. I emailed my family and
closest friends who know what I have been doing for the last 10 years and only
one has a clue to its implication.

I'm certain when I get more robust with stronger magnets it will go over 300% where
there is enough extra to do the switching. I can envision a rotary wheel that can
be kick started with a weight and then will generate 20 times the work applied
by that weight.

All of the working designs I have come up with have start  / stop motions, and some times back and forth motions.
Im not sure rotating motion can be done and still be OU.

Maintaining momentum can be done in a later mechanical stage, like the ratation of a bicycle wheel
occurs only after the back and forth (up and down) motion of the riders feet.

It just occurred to me that a magnet assisted pendulum might be
the best application of this principle where a push keeps the pendulum
going.

I have my more robust device made but need more neos and Joann Fabrics
does not carry them so had to order them online - 80 magnets of various
sizes for $12. what a deal? I used a 16 inch front bicycle wheel axle because
It is very difficult to fine tune it - just a thousands of an inch movement will
switch it from attract to repel.

Magnets will arrive Thurs.

Hi Norman

I looked at one of your magnet and pendulum designs a while back.

It's some what like the Twist Drive device in that it 's O.U. but then it undoes
the work it did (when the sliding unit is input and the rotating unit is output).

However, in the Twist Drive unit, when the fall of both the rotating and the sliding unit weights are
considered, the device is flat out O.U. .

              floor

Here is below an new drawing set / animation of an earlier O.U. magnet interactions.
