Check out this Smartphone controlled Remote Dog Feeder, it is powered by the Avnet Spartan-6 LX9 that was designed and built by Kevin Keryk, an Avnet engineer. It is build on a wood frame with a battery power supply which is housed in an Altoids tin. The batteries power the Spartan-6 LX9 board and a Digilent PMODCon3 Board. An Ethernet cable plugs the Spartan-6 controller into a port on a router to allow the system to have remote access. A servo is controlled by the Digilent board and this is what actually causes the food to be dispensed. A simple command can then be initiated by a remote device to actuate the servo and feed the dog!
