Okay, I think I have a plan for the new hardware models. Everyone tell me if I'm nuts.

1.  A single-door module with 1 reader input, 2-4 sensor inputs and 2 relay outputs, a usb serial port and rs485 serial, and an LCD connector for an optional 2x16 or whatever size LCD. This would be based on an Atmega328 chip.

2. A "master" panel board that controls multiple single-door units with RS485, an Arduino Mega/2560 on-board, 2-4 reader inputs, 8-16 alarm zones, an LCD and a slot to plug in a Raaspberry Pi for Internet servies.

What say the group?

Sounds good John!  The RaspberryPi would simplify the web side of things!   And hopefully you could use it to translate tag numbers into names for logging / tweeting etc.  Maybe the Pi would make video easier to facilitate as well!

Cheer,

Scott.

Is the Pi most effective compared to the chipset from Arduino Ethernet? Just checking.

Most definitely has ample CPU to handle the networking stack and
different protocols compared to Arduino.. also, an actual OS for
fanciness. :)

Sounds cool.

#2 with 4 readers and status for each reader with pi would be great!
