HOW TO – Pentax DSLR cable shutter release from hands-free cell phone kit

I’m trying to get into HDR photography, which usually requires some very long exposure shots. The best way to do this is with a tripod and a shutter release. I got the tripod off Craigslist, but the shuuter release was too expensive for me, so I set off to make my own. This is inspired by this tutorial for a Canon DSLR.
