Finally found some time playing with a RaspberryPi and an attached PiFace Interface board to control some garden pumps and potentially an Aquaponics setup in the near future.

Requirements

• Raspberry Pi (Model B in my case, but any will do)
• PiFace Interface board (http://www.piface.org.uk)

Base Raspian (Debian Wheezy) Install (I prefer the clean minimal install via https://githutb.com/hifi/raspbian-ua-netins).

Configure the base system as per my previous base install.
