TheFNG Posted November 26, 2006 Report Share Posted November 26, 2006 LCD Volmeter, w/ a/d converterHey, 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 Quote Link to comment Share on other sites More sharing options...
MP Posted November 26, 2006 Report Share Posted November 26, 2006 Chris,There are actually two projects by this name in our projects section. I think the project lists the tolerance, but why don't you post a link to the one you are making and then everyone will be able to give you the most accurate advice. Also, have you seen the other longer threads in this forum? There has been some very thorough discussion on one of these projects.MP Quote Link to comment Share on other sites More sharing options...
