Also just noticed this link on the same site as well. Provides for a better visual.

Yes, someone did. It didn't work.

Now, Eric, that's a really good job you've done. It seems, however, you're showing the device taken apart. Could it be that proper adjustment of the missing stator magnets is the key? I'm reading how it has been for  @RHEAD100 when replicating @zpenzif's device. Could you play a little more with these magnets until they get into their favorable positions?

I have started on this replication as it been on my TO-DO list for a while.

Just now waiting for correct magnets to arrive from Germany and some RC bearings.

Main bits are cut out and waiting. Really pleased how the CNC machine handled the Cogs, must admit

Stuck to Jan Cack?s design ratio of 4:1 and using 72 teeth on Main wheel, 18 on the Stator Wheels.

Will let ya now if anything exciting hapens

Sean,

That's truly an amazing setup!!

I shall be keeping my fingers crossed for you and look forward to your results.

Just out of interest, was your CNC machine expensive?

Cheers,

Mike

Hi Gyula,
I saw that post but I have to disagree. If you use full screen and go frame by frame one would notice:
The center post and pulley is stationary.(e,g. frames around 00:07)
The base of the lego set is sitting on top of a desk.
The 4 rotating magnets are all interconnected via the bands/strings, from their own free to rotate pullies to the center stationary one. Similar to a planetary gear system, with an extra "planet" ring
Because they are interconnected their relative motion is not the same as one just one magnet against another single one. This is a far more complex magnetic interaction system. I?ve also looked at the Lego blocks that are sold with magnets in them. Each has 2 small neo rods, oriented vertically and placed inside the 2 plastic round cylinders in the underside of the blocks. Those who have played with them before would know what I mean. Assuming from the video he used the standard magnetic blocks of this type, then  there are a total of 16 magnets in this setup. Again this is a complex magnetic interaction system.

could be a colored (transclear type) or a sets of 2 mini blocks

Back to the motor.
Since the center post/pulley is not rotating I cannot see a function of a motor there in the center.
The Lego base (blue) is  thin and so is the green rotor base, with no other wholes or possibilities of a motor shaft through it anywhere else to impart motion on the green base through the shaft.
If there is a motor and to get such relative rotation between the two bases, it would have to be mounted between them in the thin gap, with some gearing attached offset to the center (since the center post/pulley are stationary) or something else not visible on the video view.

Maybe dadido3 could come in and clarify.

Thanks
