Here's a great MacGyver tip on how to make a remote (very remote) camera trigger using a couple of walkie talkies. This idea came from the desire to take nature photography from a remote location and a unique viewpoint (although we're pretty sure by "nature" the inventor means "women's locker room").

Anyway - a very cool project. Putting together some simple electronics is required. Go find out how to make your own walkie-talkie camera trigger. [via]
