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.

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.
