I'm a bit torn about this particular hack. On the one hand it's a good example of pretty ingenious engineering. On the other hand, I'm worried about the potential for people to forget their pets.
Perhaps I worry too much. Hack A Day features a fully automated pet feeder that's been hacked together from, variously, an existing pet feeder, a sprinkler system and a web camera.
Ggiven that he's specified it's for if you want to leave your cat or dog "at home when you go on vacation", I'm a little unsettled by it. Pet ownership, to my way of thinking, is something you shouldn't take that casually, or rely on a system that could still break down to supply something as elementary as water and food to your animals. Lifehacker has covered projects like this before, which leaves me wondering: Am I over-thinking this?
