Thought i'd post up my first completed, working project! Just added a nice simple Web Interface to my HDMI switcher, so I can switch inputs from the comfort of [wherever!] without the need to track down the tiny little remote that i seem to lose on a constant basis. It runs off of my existing RaspBMC install, and seemed like a logical extension to a Home Theatre setup, where pretty much everything has a Web Interface or Mobile App. This was the last piece of the puzzle!
This project, board and code should serve as a useful example for controlling most devices using a simple relay too. The schematic is the basic Relay controlling one found around the net, but it's missing from my page at the moment- I hope to get that draw up and added for completeness soon, as well as a few other bits and pieces.
