When you're away from home and want to check on your dog, what do you do? Well, if you're an enterprising Ph.D. student, you create a custom dog-cam system/treat dispenser that runs via your iPhone, allows you to see just what your dog is doing at all times, and rewards it with treats when it isn't peeing on your sweaters.
The dog treat dispenser is made out of an old CD spindle and some cardboard. It's a pretty amazing setup, but what's most remarkable about it is that it took creator Stephen Myers a mere 90 minutes to put the thing together. Not a bad prize for 90 minutes' worth of work, especially for his dog.
