Your mind blower for the day. I mean, literally, a mind blower. Also an excellent holiday present:
Puzzlebox Orbit’s Mind Controlled Helicopter Toy (also being developed for things like wheelchairs and the software is open sourced so if you’ve that sort of mind, you can jump in as part of the inventing community here):
And the University of Minnesota in the U.S.’s brain-computer interface controlled robot helicopter that they are developing for wheelchairs, prosthetics, etc.:
In other words, science is fun!
