What can you do in 90 minutes? If you're Stephen Myers, you can set up a webcam-enabled dog-treat dispenser that you can remotely access from your iPhone. Created from a CD spindle case, scraps of cardboard, a servo motor and some random junk Stephen found lying around his house, the system allows him to watch his dog from the Apple smartphone and dispense a tasty treat.

So in all it took under 90 minutes, which hopefully wasn't too long for Stephen's dog Cooper to wait for something tasty. Full build details at Stephen's blog, here.
