Over at Instructables, there's a sweet little DIY project that can turn any 'ol point and shoot into a night vision camera. The secret is adding more infrared. Which isn't much of a secret, I guess.
Cameras that can see in the dark are nothing special. But how much detail can you really get from that fuzzy, green, Buffalo Bill-o-vision? The Color Night Vision Camera, though, can reproduce red, blue, and green even through the pitch black darkness, using the magic of infrared.
