Energy Efficient Cat Camera

[Juergen] sent in his catcam project built. He used an inexpensive 1.3mp keychain camera with an ATTINY2313. The controller keeps the camera shut down until it’s time to take a picture. Then it powers it up, takes the shot, and returns to low-power mode. The cat adventures are actually kind of interesting. It wouldn’t work from under the car, but anyone feel like gps tracking their cat?
