Hardware that works with sprinklers_pi

I had 9 zones to control so I decided to design my own hardware rather than go and buy OpenSprinkler PI and an expansion board. It also came out a lot cheaper than even just one OpenSprinkler PI kit. I thought I would share it with the world. If you don't want to include it directly in your project that's fine but I thought it would be a nice addition. Otherwise, I'll just post it on the forums. Thanks for the great software!
