Matt asked about the option of having a backup battery for the OpenSprinkler, so I prepared a short blog article to show how it can be done. Basically, you just need to get a 9V battery (or any battery that can provide 6V or above voltage), connect the positive lead with a diode (such as […]

This is a collaboration between me and Chris Anderson (editor-in-chief of Wired Magazine). A video demo is included below. For details and how to order a […]

After finishing the previous minty water valve controller, I decided to make it an Arduino shield. This way, I can easily stack it onto other shields and extend its capability. I also added a few input buttons, and a DS1337 real-time clock, so that it can keep up with accurate time. Now the circuit has […]
