Tired of switching having to manually switch between his headphones and computer speakers, Peter Lavelle decided to go all out and built a LAN-controlled audio switch to solve the problem. Using a (double pole double throw) DPDT relay, Arduino and ethernet shield, he can now control where his sound goes from the comfort of his browser. While this solution is probably overkill for this particular application, the project is well documented and would serve as a good starting point for more complicated tasks.
