Intervalometer: Arduino + old(ish) Canon digicam

Nicely done! I'm fascinated by arduino-camera interfaces. Thanks for sharing

Can you think of any Arduino camera interfaces besides an intervalometer or some form of tripwire/tripsound/etc? I'm trying to think of a new project.

A few months ago I built an IR intervalometer for my Nikon D90. Then after I had it working but not assembled into a housing, I did some quick math and at 24 frames per second, five minute of time-lapse will need 7200 exposures. I just can't bring myself to put that kind of wear and tear on the mechanics of the camera. It's rated for 100,000 exposures and I don't want to wear out the $1000 body prematurely.
