I would like to see Ben either create a simple Mind Control headset (similar to MindFlex or EMOTIV) or hack an existing product like the MindFlex. This device would be very useful for controlling your PC or other hardware projects. I could also envision using this device to control a game console, so people with disabilities wouldn't even need a modded controller. Ben's controller mods are top notch, but what if we could eliminate the game controller altogether.
Here Is a Similar Hack from Instructables [user feedback is very mixed, so I know Ben could take this idea and make it work well]:
Control any gadgets with your Brain! (Neurofeedback with Arduino Microcontroller)

Thank you Ben for all your fascinating and informational videos.
