MindWave Cat Ears

Some time ago, a friend of mine asked me to make her a pair of mind-controlled cat ears, and I said, "Oh sure! I can do that."



In my defense, I'd had a bit to drink that night, and didn't think she was serious.



She was.



(Oh, dear.)



On sober reflection, I became curious about whether I could do it. All the pieces seemed to be present:



* The Neurosky headset had just been featured in Make Magazine.



* The arduino microcontroller makes doing simple robotics like this relatively easy.



* The Makerbot and reprap printers make it possible to iteratively design custom hardware, which was going to be really important.



So instead of completely and utterly insane, the idea turned out to be merely odd. But doable.



Anyway, if you've ever woken up and said to yourself, "I'd like to strap a pair of robotic cat ears to my head, and interface them with my brainwaves," your wish has now come true.
