Ooooooooooo, I am intrigued. I have toyed with the idea of buying a Rasberry Pi for awhile now. I think when I get out of this desert of Afghanistan, I may purchase one. In a past life I was an AMX programmer, so I enjoy writing code to control things and I am a fan of RFID. What are your ideas? Are you trying to actuate by proximity or by a button press? I am assuming since you metioned NFC, you are working on a proximity solution. Totally interested in watching this develop.
