LCD Volmeter, w/ a/d converter Hey, has anyone built this thing before? I'm using a 12v 9a atx ps unit as a power supply. Can anyone tell me what power rating I should use for the r3 1% tol reisistor, which are the leads to the voltage to be tested? It resists the current depending if I'm measuring 0-2 or 0-20v. and where is a good place to shop for electronic compnents? Thanks anyone, Chris
