Hi Guys, thanks for the help, I found a few sites. The problem is that this is to much for what I need... I have a couple of RF TX and RX from a remote control project, could I use the TX as the transmitter and build some receiver/detector to detect the RF? how do I make it directional? any ideas or links welcomed. best regards Luis -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu]On Behalf Of Denny Esterline Sent: 30 June 2006 11:02 To: Microcontroller discussion list - Public.
