I've been doing some searching, and havent really come up with anything other than finding a circuit that does use a 16C54, fed directly from the mains (or pretty much so) and decodes the X10 data. Since X10 is now public domain (I think...since the patent expired?) has anyone done this, without using the PLIX or some other commercial thing? I'd like to build some X10 capability into a few things, but hate to pay the price for it. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp -- http://www.piclist.com hint: The PICList is archived three different ways.
