  1. So I believe it’s using gyroscopic precession to keep the Harry Potter wand upright. A sensor measures the the rotation in an axis, then the rotor rotates with the spin axis perpendicular to the axis of rotation to compensate for the angular motion.

    Very interesting application. I didn’t realize this was possible to that extent. I would be interested to see the limits of control. Like what initial positions could it correct? Any have the sauce for this??

  2. Wouldn’t it already stay stable with just two perpendicular gyros? No need for all the other stuff as it would rely on whatever the effect was called that made it hard to change the axis of a heavy flywheel.
