Permanent magnet OU machine working today

Great build there.  Those neutral points are indeed interesting.  I am not sure what you can do with this but, I have not seen this before so...who knows?

Yes, some nice machine work on there. That "neutral point" is the same thing I'm illustrating in my "Nikolayev trailer hitch" videos, but you've implemented it in a very nice way using the linkage.

This design was shown to work in the simulator but I was sure it would not work and now I am forced to take the next logical step and modify the block holding the diametrically polarized cylinder so it can rotate.

The cylinder is intended to rotate at the neutral point where there is equal repelling and attracting forces and logically it should rotate with near zero effort but I believe this must not be the case or this device would likely be OU.

The rotation of the cylinder magnet must require work to increase the potential of the system or the energy expended on first release could be used to rotate the cylinder magnet at the end of it's stroke and restore the potential required to traverse back. Then repeat continually until it breaks.

Actually, what I think you will find is that the orientation of the cylinder magnet at the "neutral point" is unstable; that is, if it is free to flip over (or rather rotate 180 degrees around its long axis since it is diametrically polled) , it will, and then it will crash into the stationary magnet by attraction. The mounting you are using is keeping it from flipping over. In my Nikolayev trailer hitch, the analogous magnet (bar magnet endwise-polled) is prevented from flipping over by being constrained in a tube. In my system it would also be possible to stabilize by being spun around its axis, I think, like the original Levitron toy.

It would be interesting to see if I'm right about this in your system. Is there some way you can make it possible for the cylinder magnet to rotate freely in its mounting?

I am nearly finished with the changes that will allow the cylinder to rotate.
It should not crash into the stationary magnets because it does not do so now and the neutral point exists at both ends due to the large magnets arranged as mirrors to the other side.
I think it would take some work to rotate it but the neutral points will still exists the same as they do now.
Once the cylinder is rotated it will simply work as it does now but in the other direction.
