While not ready for retirement I'm getting up there and I am buying a house soon with between 1/4-1/2 acre piece of land attached. Its a reward and opportunity for me to experiment with a large "garden" for myself and my family and maybe enough for friends or to can/jar.
I get this impulse but I'm still plugged in enough to want to automate things. I'm looking at farmbot on kickstarter and thinking how I could build my own, program or automate various systems and sensors. I'm extremely excited about having one foot in both worlds.
