Watering
I wanted to throw together some sort of system to automatically water plants, or at least to let me control the watering remotely. I never completed it, but there are solenoid valves available, and Raspberry Pis and similar single board computers have GPIO you can use for that sort of thing. I've got some of the parts, and will put it together one of these days.
Right now, I go outside and turn the hose on for a sprinkler in my garden. I've got a setup nearly complete with some black plastic pipe that runs to some key areas, which will reduce the need for a garden hose. It's a step in the right direction. But I'd like to be able to log in to something from anywhere in the world, and turn the sprinkler on for fifteen minutes.
I'll add it to the list of projects. It is kind of important, considering that I'm trying to actually grow things in my garden other than weeds, and I'm occasionally out of town. Plus, honestly, it's kind of a neat project.
