The patent application for the device is available online. US patent number 2007/0170798A1. It is tough to read though. It reads like it was translated from French and Chinese by someone who didn't understand the invention, which is probably just what happened.
Ernshaw's Theorem states that it is impossible to create a static magnetic field that can levitate an object stably on all axes. The configuration of permanent magnets in the Levitron Revolution holds the levitating magnet stable along the vertical axis and is also stable in tilt. But along the horizontal axes the floating magnet acts like it is balanced on a pin.
The Revolution corrects for this using (apparently) four electromagnets to nudge the floating magnet back into position. Position is sensed by hall effect magnetic sensors in the platform. The four LEDs in the corners indicate which electromagnets are active. When the LEDs are on the electromagnets are off. The idea is that there is no continuous power demanded by the electromagnets, just slight nudges to keep the floating magnet centered on the magnetic field created by the permanent magnets. In normal operation you can sometimes see a slight flicker in the LEDs, but mostly they just appear lit and the electromagnets are off.
The electromagnetic correction system works quite well and will normally keep objects levitating as long as power is applied.Read more ›
Unfortunately what they don't mention is the quality of the base seems to degrade incredibly fast to the point that it becomes impossible to keep the thing floating.
I received it a week ago, had about two good days of fun with it, and now it's totally busted. The magnet pulls to the same corner every time you try to balance it, and when you do manage to get it to stay centered, it'll float for 3-5 seconds, just long enough to make sure you know it's mocking you, and it will slam back down to that same damn corner again.
In 5-10 years, when they iron out the many horrendous flaws,these guys are going to have a real sweet product on their hands.
But right now, I spent $100 on an ugly paperweight, and the guarantee I'll lose every argument with my girlfriend over wasting money on dumb crap for at least the next year.
So bottom line is, when it works, it will work only for small amounts of time.
Finishing and overall appearance is better than their competitors, but as a whole this class of devices still lack development to be really a hit.
