Have a look on the Piclist PCB competition page, you'll see a water sprinkler project there. Or alternatively purchase a back copy of Nuts & Volts (March 2003) and see a slightly amended circuit there. There is also a rain detector add on not as yet published. I even have a swathe of PCB's staring at me as I type. Note that the PCB on the Piclist page is incorrect it shows a 0.6" DIP when it should be a 0.3" DIP. I missed that the first time around.
