From Make, an experience trying the NeuroSky headset to control a copter with brain waves:
If launching virtual vehicles at people isn’t cool enough for you, Puzzlebox has developed a more physical manifestation of your mental might with their spherical helicopter Orbit. Through the power of concentration, the user can send the little drone into the air (or into a crowd of innocent bystanders as there isn’t any form of directional control).
As I learned in the short time I played with the Orbit (and throughout my years of formal education), trying really hard to concentrate is not effective at increasing your concentration levels. When I focused on listening to someone talk or reading a paragraph of text, however, the little guy jumped out of my hand. But then, the excitement of seeing it fly stole that concentration, sending it crashing to the ground. I’m sure with a little more practice I’ll be able to levitate it like a swamp-lodged X-Wing.
The Puzzlebox Orbit project is open source. They have an Instructable that shows you how to create and mind-control your own flyer. They launched a successful Kickstarter campaign the end of last year and from that has come this commercial product, which you can buy here.
