For me, playing with tech is part of the reason I have a backyard farm. So far I've just played with very basic things like sunken hose irrigation with timers hooked up to a rain gauge so it only waters when there's no rain, but I'd love to have the time to look more into the robotics side of things.

For those of us who sling CRUD sites all day long, the opportunity to dig into more machine/computer interaction is just fun.
