Procyon AVS Users: I've developed an Excel 2007 based tool to assist in the intelligent design of the visual segments of the Procyon AVS. I have not tested it with earlier or later versions of Excel, but it will likely work on later versions. It has taken me almost 2 months and well over 100 hours of sometimes very frustrating coding time ..... but IMHO the end-result is well worth it. I won't go into the gory details in this initial posting; but, if you have any questions about the code or mathematics used, please feel free to shoot me an e-mail or reply to this thread. ...
