Making a Lego fan that floats on a cushion of magnets #lego

Now that we can make some Lego levitate on a cushion of magnets, can we also make it spin wirelessly? In this video, we explore a sort of brushless motor made of a copper coil, some magnets, some Lego and a reed switch to send pulses to the coil. This allows us to drive the floating fan, without having to touch it.
