Sounds like a neat setup. A simple 555 would probably have done the trick as well, but that would have required more effort. This design proved to be a little more flexible, and easier to fine tune than anything else that's been mentioned so far would be (so far as I can tell.) It also required very little electronics expertise. Up next: when some friends at MIT finish building a giant cannon capable of shooting campbells soup cans, I hope to photograph some hot soup-on-wall action, although I may hide myself and my camera behind plexiglass for that one.
