Way back in March I posted a video link (Dog Ballistics) showing a motorized ball launcher, allowing an automated way for a dog to play fetch.

Now, in my tireless scouring of the intertubes (is calling it tubes a felony now?), I find plans to build such a device. Your Dog Wants A FetchBot. It doesn’t have the automatic inclination adjustment, but it still launches.

[T]he cool part is that it’s built mostly out of a cannibalized document scanner. It contains some simple electronics to control the motor, but it’s totally something you could build yourself in an afternoon. C’mon, you can do it! And your dog would love you forever.
