Laser Dog Monitor

via Raspberry Pi

Dave Young lives in Denver with a baby, a wife, and a dog called Penny. Penny’s a good dog (good dog, Penny!) – she’s a softie around the baby, walks to heel, and doesn’t destroy things. All that good dog stuff.

But Penny has one weak spot. Dave says:

Her only issue is that she goes BONKERS for food. My wife and I have done a great job training it out of her when we’re around so we no longer have to worry about a cheese board sitting on the low coffee table, but I know she gets on the counters any time we are away. Sounds like a job for a machine!

How’s it work? There’s a laser tripwire, which triggers audio of Dave saying “Hey!” in a COMMANDING MANNER. The setup also takes a picture of Penny’s infraction using the Raspberry Pi camera board.

Full instructions are available over at Element14 so you can make your own. I’m already thinking about ways you could expand this project: Mooncake, the Raspberry Pi cat, doesn’t respond well to voice commands, but we think a Pi-powered water pistol could be just the ticket on those days we want to defrost prawns. Ideas for your own feature-creep in the comments please!
