Use the web to control an HDMI Switcher

Easy as ... click.

Universal remote controls are a natural want.  I know I hate having 100 remotes for everything remote control.  So what do you do when you start getting used to using your phone as a remote (via web interfaces) ?  Well start converting your other stuff to be controlled via the web too!

Dalgibbard has an entertainment center using XBMC and a Raspberry Pi.  But the HDMI switcher uses an infra-red remote control.  So naturally Dalgibbard hacked the switcher to be controlled by a web interface on the Raspberry Pi.

The HDMI switcher is wired up to the Raspberry Pi via a relay and a few discrete components to the GPIO pins.  The pins are controlled by a python script that is executed by a web page using PHP and Apache.  Simple and efficient.
