Magnets, motion and measurement

[norman6538]

Floor I  quickly cobbled together your twist drive and got 11 units (1 washer) of work in to start the twisting/lifting giving 24 units of work out (2 washers) which gives 218% OU. Remember my work here is quick and dirty and between all of my nursing duties to my wife who has cancer but is progressing.
1. I used 2 stacks of RadioShack magnets with the hole in the center.
2. In the back of the photo are the 2 washers lifted.
3. To the right is the 1 washer that drops and activates the twisting/lifting work out.
4. I used a stainless steel bicycle spoke to make a crankshaft quick and dirty to rigidly hold the twisted magnet.
5. the box on the right limits the drop of the arm and washer at the point that max twist/lift is achieved.

I discovered that its best to start with the twisted magnet below level to get max twist/output because if it gets too high it will be stuck there. I don't think this is as well tuned as Floor's because if the magnets get closer than 1/8 in. they stick together so I put a spacer in between them as a stop. I think  I can tune this a little more but have limited time for that.

The the first photo is twisted/lifted up and you can see the 2 lifted washers in the back . And you can see the crankshaft that allows the twisting magnet to rotate. The second photo shows the 2 washers down and the untwisted magnet.
The magnet to the left that has the hole is pulled to the right  by the dropping single washer  twisting/lifting the 2 washers in the back. In the second photo you can see the magnet is tilted down. In the first photo that twisted/lifted magnet is tilted up in the back and you can see the 2 lifted washers in the back.

In summary as the magnet on the left moves right it twists the magnet on the right lifting the 2 washers hooked behind to the crankshaft.


Thank you so much Floor for all of your diligence and for sharing this with all of us. This makes me very excited. I can taste a self running machine in  my mouth.

I cobbled together another Floor twist drive device and it measures 533% OU. That surely is enough extra to repeat the process and handle the losses in the switching.

details
The activating weight is a small washer 1/4 oz. and it moves up and down 6/8 in.

The lifted weight is 2 1/2 oz. washers that are lifted 8/8 in. So the activating units are .25 x 6 = 1.5 units in
and the lifted units are 8/8 in. up x 2 washers x  .5 oz. washers giving 8 units out. giving 533% OU.  But for margin of error purposes I will count on 300% which is plenty.

And in this embodiment I used a stack of 4 RadioShack magnets that move to twist a stack of 2 of the same magnets. Since the mag field is much stronger with the extra magnets I did not let the magnets get closer than 3/16 in. to reduce the attraction when twisted causing more work to reset for another cycle.

So to make this self run with human switching replace 1 of the .5  oz washers with 2 1/4 oz washers and humanly place the lifted 14/ oz washers where they are needed to activate the twisting/lifting.

And to make it self run we need a good watchmaker of which I am not... But I'll try.

Floor you really have a winner.

Many of these magnetic tracks abound but it takes a push to get it started before the magnetic track and therefore it will not jump from one track to another. He claims it goes up hill and that is good if it can be replicated by others.

Floor has the best thing going for now as far as I know but keep it simple like I did. Floor wanted to get good measurements and that he did very well.

!. Yes You can get them to go up hill.
2. Yes you can get them to release at the end, but only because they fall from the table
or at least lower than the starting height.
3. I don't know exactly how those magets are arranged, but he started of by saying
they are repelled at the start end the ramp.
4. He didn't sat it would self loop, and he knows it will not.
