Thanks to those that replied...after a little digging I found one at www.viddata.com. Now I've just go to build it, debug it & write some pc software :) CR > -----Original Message----- > From: Olin Lathrop [mailto:olin_piclist@COGNIVIS.COM] > Sent: Tuesday, 17 October 2000 10:48 > To: PICLIST@MITVMA.MIT.EDU > Subject: Re: [PIC]: Project Idea, anyone done it already? > > > > I've thought of what I think would be a good project for a > pic.
