Raspberry Pi is a dog's best friend
Dog may be man's best friend, but in this case, Raspberry Pi is easily a dog's best friend forever. Judd's owner took on this project as a learning exercise as well as a chance to do a project centered around his dog. He's using a Raspberry Pi to check an email address. When there's a new message, the machine dispenses a treat and snaps a picture. Judd takes care of the rest.
The code and plans are available on the project page if you would like to make a new best friend for your dog. The new exercise program for your dog that will be required if email traffic is heavy is not included.
