Wow!  Nice find.  I translated his description and all it said was " home made levitron."

I tried translating a few of his comments answers and did not get very much at all.

It looks like he has re purposed some other type of device and hacked it into this device.  At first, I thought it was a hard drive...but now I am not sure.

I see he has the leds for feedback and it does hover very well.

Maybe someone on here that speaks Russian can contact him and get more details?

Thank you for posting this.

Bill

Interesting. It looks like a floppy drive enclosure of some kind but I've never seen one with a big heatsink on it like that. It certainly acts like the commercial version. I was surprised to see no disturbance when he passed the rod beneath the object, interfering with the light from the LEDs, so I'm wondering about the LEDs still. Are they part of the sensing loop, or just for show? I dunno.
I've put that project on the "back burner" for now since my Hall sensors still haven't arrived from China. Should be a few more days, not too many I hope.

From the translated web site linked above, he's using hall effect sensors and a differential amp.
The LEDs are just for show.

Lakes:

Thank you so much for posting the translation page.  So, hall sensors appear to be the ticket here as well then.

TK:

At first, i thought it was a hard drive package but then, as you say, it could also be some other type of drive unit.  The heat sink confused me as well but, I suppose that could easily have been added to the drive enclosure.  The fact that he is using a heat sink is probably good news as I doubt the Levitrons are using one...or at least not a large enough one as there seems to be some problems with longevity with those.

Nink:

Those videos are great!!!!!  I think it was the 3rd video where it showed like 5 small wound electro mags on the bottom.  It is great to see that all of these variations appear to work very well.  I will look at their youtube accounts to see if there are any vids with schematics or how to build.

Man, I feel like we are really late to the party here.  I thought this would be a cutting edge project, but now we see this is not the case, ha ha.

Great find and thank you for posting.

Here is another video from the first video guy posted above:

https://www.youtube.com/watch?v=NyzgB7Ah3IM&list=UUhRJmfON7S6q-TaiUnarWXg

This thing is beautiful!!  Evidently, this video was done prior to the other one we have seen.

That might be the coolest device I have seen yet.  I want one of these floating in my living room.

PS  Holy crap!  Here is another video from yet another guy:https://www.youtube.com/watch?v=eexeEg2N7kw

Check this guys channel on Youtube.  He has like 10 videos on his devices showing his experiments and progession.

Another type built by some UBC physics students it appears.

MIT open courseware showing how to levitate a coil of aluminum wire 3" over an aluminum plate using Lentz's law.  This appears to use a lot of power though.

Put 110v into a coil and place over joining corners of 4 aluminium plates

Similiar to 4 corners of diamagnetic pyrolytic graphite and 4 neo magnets

The induction current type levitating an aluminum plate uses a lot of power and things can get really hot quickly!

Which is why I much prefer this hall effect/magnet system which uses less power.

Btw, the "Levitator Prototype 1 "rotating crystal display was awesome!

This system using an arduino and a H Bridge is (I would guess) probably the one that Tk will be using.

I like this one, from the same maker as the Arduino one above, but not using Arduino I think:

The sphere magnet doesn't want to flip over!
