$3 Remote Shutter Trigger for Canon Digital Rebels

This is a cheap, quick way to make a small remote shutter trigger for Canon Digital Rebels. Basically, you just need a $3 hands-free phone headset with a 2.5mm plug (NOT 3.5mm). Pop open the case and cut the wire leading to the ear piece, tie it off, then close it back up. Plug into the camera and you're good to go. [Instructables]
