Hello Terry, Not a problem. Ill make up a bit of a test board before I go posting anything so I can test how much current it can provide, proper voltage ranges, etc etc so some poor bastard doesnt get screwed, but I will probably have something together by about tuesday or wednesday. Chris if the test board is a complete success and you dont feel like making one up yourself im sure I could get that one to you somehow.
