Finally, a good use for those EEG headsets. [Andrew] has set up a system that will turn his TV on and off if he focuses hard enough. He’s got the software set to trigger an IR LED when the “strength” gets high enough.  When the action starts, around 4:30 in the video, you can see that when he raises his arm the meter on the screen begins to raise and the TV turns on. Though not immediately useful, we can’t help but get a little excited seeing him literally turn his TV on with a thought.
