scottnj Posted September 11, 2005 Report Share Posted September 11, 2005 I want to make a comuter speaker/mic vs headset selector switch.I want to me able to selectspeakers = (none, desktop speaker, headset speaker, both)mic = (none, desktop mic, headset mic)I was thinking:on/off switch for comuter speakeron/off switch for headset speakerdesktop mic/headset mic selection switchon/off switch for mic muteMy questions are:a) Is there any thing I can do to minimize noise added to the system (pcb layout, type of switces,...)?b) What does each section on the round plugs corespond to (where do I put my switches)?c) I want to add LEDs to indicate what is turned on, is the only way with dual pole switches? Do soundcards provide any dc power for the LEDs, or should I just use a battery?I am sure you can buy this some where but I want to make it myself.
