Automatic LCD Sunglasses

Ben Heck built a pair of automatic sunglasses a few weeks ago which inspired this hack. I built a light detecting circuit and connected it to the LCDs in these automatic shutter 3D glasses to make a pair of automatic sunglasses! Here's the project page with a schematic: http://hackaweek.com/hacks/?p=978
Note: build these at your own risk! These are probably not a good filter for UV rays AND they're made of fragile thin glass which. if broken while wearing them, could really hurt your eyes!
