Bark Activated Door Opener Could Leave You in the Doghouse Beth Snyder July 5, 2013 If you have a dog, you are familiar with the seemingly endless dance involved in letting them out. Then back in. Then back out. Then halfway between in and out. Some folks opt to leave their dogs outside for great lengths of time, but then that can lead to problems with your neighbours if your dog is prone to barking, and it can also lead to animal cruelty if the temperature is too hot or too cold. One option is to install a pet door, but then you run into the problem of it maybe not being as secure as you’d like, or letting in cold (or hot) air, or bugs. David Hunt was well aware of the problem, and decided to create a DIY project involving his already existing door, some extra hardware, and Raspberry Pi. At first glance, it seems like a brilliant idea. He named his creation Pi-Rex, and what it does is automatically open his door when his dog barks so he can come and go when he pleases without requiring human assistance. See? Kind of brilliant. But wait. Here’s my thought: What if the dog barks because there’s a stranger on the porch, attempting to break in? The door opens, allowing said burglar instant access to the house. Seems impractical at best. What if your dog is the type to bark for no apparent reason? The door opens. What if you’ve spent a large amount of time training your dog to not bark? The door doesn’t open, and you potentially have to come home to a rather nasty mess. I don’t know…this seems like a great idea when you first look at it, but I’m seeing way more potential problems than the single solution. Kudos to David, however, for seeing a problem and being creative enough to find a solution that seems to work for him. I just don’t so much see it as a good idea for everyone.
