A web-enabled audio switch

arduino_networked_audio_switch.jpg

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.

  1. This is cool. I have a headset with a USB soundcard. I setup AutoHotkey to change my default output device in Windows 7 with a key combo (from my main speakers to my headset or to my digital out/hdmi). Not quite on topic, but it works for me.

  2. I bought some AKG K-271 headphones which sense when you’re not wearing them and turn off the headphone speakers. I’ve always wanted to make a controller board that sensed the change in resistance and re-routed audio whenever you took your headphones off. =)

    1. I dont see why you’d need to detect the change in resistance, just have a switch or other sensor to determine when the headphones are “stretched” over your head. Not to imply anything…. :)
