    mechanical volume control for computer sound

    Edit: I originally started out with a 25 ohm potentiometer and I couldn't get it to work. I think the current on that line has a really low rating. I say that because it can power a set of small headphones (ipod) but it will not even budge a 4 ohm speaker on it's own.

I cracked open a set of headphones we use for the field at work and it had a B500k Stereo Pot in it. I couldn't find any here in the USA (or I just didn't know where...
