Laser Dog Monitor

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!

That dog doesn’t like being locked up – I’ll bet you a Penny for a Pound.

That’s a really Ruff pun.

There’s an application hidden in here for getting your kids out of bed at a certain time every school morning and escalating the severity of the system’s response if they don’t move in the direction of getting dressed and downstairs within a certain period of time. I think the water pistol idea works well in this scenario too!!!

I misread the title as it being about monitoring laser dogs. A “laser dog” sounds awesome.

You could identify it if it got lost by putting a laser tag on its collar. Badoom tish.

This reminds me of the much older Blender Defender. I had offered to use a Pi to build a similar device for my Sister and husband’s house of cats.

This seems like a very practical use for the pi!
