p_leriche @ instructables.com build a USB volume control which is simple, cheap and extensible. Check it out:

I’m not the first person to publish an Instructable for a USB volume control, but I think this one is about as simple and cheap as it gets, and at the same time can be extended at minimal cost to various other functions such as:

  • Mute, Play, Pause and various other media buttons
  • Keyboard LEDs such as Caps Lock, Scroll Lock and Num Lock (a kana LED is also defined for Japanese users)
  • Application launch buttons such as browser, email, calculator etc
  • Browser navigation and other application control buttons
  • Gamepad buttons
  • System buttons for functions such as Sleep, Hibernate, Wake, Power down
  • Mouse buttons and movement

and many more, subject to support being provided by your operating system. Mine implements the volume and mute functions (mute by pressing the knob) and the 3 main keyboard LEDs.
