I wanted a way to mount the iphone on a tripod so I bought a cheap iphone case, some right angle aluminum extrusion and four 4-40 x .5" flat head screws. The aluminum extrusion is 1 x 1 x .125" and can be found at your local hardware store. The half inch screws are kind of long but that's what I had on hand. 4-40 x .25" would also work. I cut two 1.5" lengths of the aluminum extrusion and drilled holes to tap the 4-40 threads into one side and 1/4-20 threads in the other side (your tripod should use a 1/4-20 screw to attach to cameras). Next I drilled and countersunk the 4 holes into the iphone cover to mount the aluminum brackets. When you screw the brackets on, the screw heads should sit below the inside surface of the iphone cover. Cover the screw heads with tape to protect your iphone from being scratched. Insert your iphone and attach it to your tripod and you're done! Now you have a stable camera mount for photos, movies, stop motion, time lapse or whatever you want.
