Tomato irrigation

No hack will be more readily accepted by the significant other more than an automated vegetable watering system. [Jouni's] homemade rig keeps those tomatoes happy with just the right amount of moisture. A bucket serves as the reservoir, a submersible pump gets the water to the soil through a bit of plastic hose. An Arduino monitors the soil sensor, watering and tweeting about it when things dry out too much. Don’t miss the soil moisture sensor post if you need some tips on how to get that end of things working. The rest is pretty straightforward.
