Mind controlled TV

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.

Convert an early 60s Polaroid to modern film

[Adam] sent in this cool project. He has modified a Polaroid J66 camera to use modern film. Most of the initial modifications look fairly simple, but things get a little more complicated when they also convert it to a fully manual camera. There is a section that explains a neat little trick of using a cheap solar panel attached to your computer sound card to figure out what ISO the camera is shooting at.
