make sure the back of the eye is clean and not shorting anything out. One way to check if it's the eye is just disconnect it and leave the frame off with a battery in it before you go to bed. When you wake up in the morning, check to see if the battery still has a charge. If the battery has a charge, then your eye is shorting out somewhere.

You need enough pizza and Diet Coke to stick in your refrigerator, a cheap PC to work on, and the dedication to go through with it. We slept on floors. We waded across rivers. -John Carmack
