It is true that rigid and precise construction are required.

After I do this next presentation, maybe I will put together a materials list
and complete drawings and instructions topic ?

There are many more open source builders for this project
I believe people are a bit spent or shellshocked from the world
Around us ATM


That being said
One good anomaly will ring a bell to wake/bring the open source builders to the call !
( and I will knock on many doors to spread the word !)


With Tremendous gratitude

Little update.

Thank you Ramset.

A photo of my test bench. 

I'm epoxy gluing the fixed and output magnets, each to its own fixture / mount.
Less clutter / no clamps and also this gives increased precision.

Cleaning up and organizing the test bench / area.

I finally got a wheel together enough to see that there is no significant sticky spot and this is the real deal....But its too ugly for a photo....

So guys go for it.....But due to the rigid construction and precision and the opposite angles it will take a while to finish....

I just wish it could be scaled down but smaller magnets have less power and tolerance has to be much closer. I wish Butch Lafonte could see this...

You already have a big winner I recommend you stick with that.
and your have 2 of us on this list that have seen but not fully measured the OU.
Unfortunately the smaller magnets do not have enough power to see this force.

Bonjour Sol,
Sujet très intéressant...
Juste une question avant d'aller plus loin si vous acceptez de me répondre.
Utilisez-vous des aimants en ferrite ou en néodyme ?

@ Norman
The link (repeated) below is for a possible / later application to the "Magnetic force shield 1" design.
Thanks. Don't worry I'm not modifying the "Magnetic force shield 1" at this time.

@ all readers

I am not at this time asking for replications.  Any one who
wishes to build one, may of course do as they wish.

Please understand.

1. I am not an expert nor an authority on magnets.

2. To the best of my knowledge, this design is, other than its presentation
@ the O.U. forum, novel.  It is the responsibility of any one selling it, to verify this
for their self / avoid infringements.

3. If it is in fact novel, then, this design is open source.

4. If you build it, please do not refer to your build as a replication unless
it is     very, very,    near to identical to what I have presented. 

5. You may of course build what ever you like. 

Just don't call it a replication, even if it has very minor variations from the present
design. 

You may refer to it as a variation or modification of the design.  But if you call it a
replication and if in my opinion, it is in fact a variation, I may consider it as a false
representation.  Please do not misrepresent design variations as "a floor design" and
so on.

6. Don't present your build in this topic, nor in the "Floors MMM-2 builders board"
unless you have presented it (at least in part) in the main O.U. forum. 

If you wish to start a topic in the "Floors MMM-2 builders board" contact me for permission / my
vetting, of that topic / build.  This is in the opening statement for this board
                           @ https://overunity.com/18496/un-hassled-exploration/
       Read it ?

Please read and understand the terms of use of the O.U. forum as well as the terms of using
this,  the "Floors MMM-2 builders board"

   best wishes

Floor are you sure the mags will separate 2 inches. I'd think more like 1 but that would  still be
OU 20....

Norman

Sorry.  You are correct more like 1 inch (shield out) in order to still have a second
out put (by attraction) once the shield is re installed ?  I'm hazy on it right now.
Looking at several designs in a short span, gets me mixed up to sometimes.

Unless 2 or more units were combined (series ouputs). In which case input to output
ratio is unchanged, but longer output strokes will be easier to efficiently utilize.

Also
   I need to finish / button up a home repair project I've got opened up right now.

General information

The testing or measuring of these various magnet interactions sets generally
follows along these lines.

Testing hand held magnets, just by feel

Mounting one or more of the magnets used in the set, on a sliding track,
then testing by feel.

Taking a few measurements in large increments of force and distance.
This gives a rough picture of the over all force to distance curves that are present.

A first set of measurements of each action. 

Some math as force averaging, additions and subtractions and possibly
conversions necessary to convert to joules etcetera.

Final overall totals of inputs to outputs and the overall ratio of in to out.
... ... ... ... ... ... ... ... ... ... ... ...
The above is all preliminary.

If everything is looking good...

Generally...

Check parameters, accuracy of the weight scales, accuracy of the levelness
of the rail system, accuracy of any alignments in terms of  90 degree alignments.

Each force and distance measurement is repeated five times and logged individually.

The calculations are done and checked.
... ... ... ... ... ... ... ... ... ... ... ...
This can amount to from as few as 40 or 50  measurements or up to as many as
400 measurements.

Note.  I do not always follow through to this degree of rigor.
for example in the "Magnet shear to direct pull work ratio" topic,
I did not follow up with this degree of rigor.

I was lacking the energy and motivation to do so on that day.  Otherwise
I would have also presented those logs.

"Closer stronger further weaker" wins again. My tests show about 200% for 3/4 x 1 inch magnets and for the domino sized it is barely over 100%.  I used two drawer slides to get the linear movement instead of the arc of a bicycle wheel. My results do not warrant the waste of a photo upload...

I find it quite interesting that Floor has not recently followed up with any measurements.

Therefore I suggest that Floor......... and I leave that for you to fill in the blanks...

@ Norman6538


This PDF, ( Kedron Eden Project) says that using magnets of smaller dimensions is best.
Magnetic force drops off with distance.  Two magnets of large physical dimensions will  not
interact with one another in nearly the same manner as will two small magnets.

https://overunity.com/18551/magnet-shear-to-direct-pull-work-ratio/msg560757/#msg560757

This might not seem reasonable, and I myself, do not understand fully enough to offer
a good explanation. All I can say of that, at present is,  simply put...


The force from a    20   mm x 5 mm x 5 mm neo magnet (poles at the ends) will drop off
as the distance from a pole increases. 

Take a force to distance measurement at 20 mm from a pole (magnet's length) , and compare
it to the force to distance measured at 5 mm.

Do the same with a   40   mm x 5 mm x 5 mm magnet (poles at the ends).
The length dimension is doubled, but the field does not extend to twice as far as does
the field of the 20mm long magnet.

At magnet's length (40 mm) from a pole, the force will not be as strong as the force from
the 20 mm magnet was, at 20 mm (magnet's length).

This is a simplistic example but with other shapes of magnets the amount the
field strength decreases with distance can be even more dramatic.

As I said, the / my explanation is a simplistic one.
