I’ve been meaning to write about this for ages: I hate watering the garden. I’ve met Ray, the Mind Behind, a couple of times now, I actually *own* one of these boards, and…I hate watering the garden. Did I mention that?
If you hate watering the garden but enjoy messing around with computers, OpenSprinkler Pi is a no-brainer. It’s the cheapest and most configurable system of its type I’ve come across, it’s open source (and this means that Ray’s not the only person working on it – tools from the community like Rich Zimmerman’s Sprinklers_Pi software add features like weather control, so you can adjust your irrigation depending on your local weather forecast), and there’s a big community adding features all the time.
You can read more at rayshobby.net, find links to a ton of code, and buy a board there too. We highly recommend you take a look; Ray’s a great guy, and we love what he’s doing with the Pi.
