Sounds like a cool project.

A few questions though:

  1. Why a 7" LCD? Why not an LED sign like this (or the DIY equivalent) for example:

  2. Why an external EEPROM? Even the ATTiny85 has enough EEPROM space for various countdowns/config settings. the arduino due does not have eeprom, so i must use external eeprom

  3. Speeking of EEPROM space, why the Due? Seems total overkill for something like this, no? please refer to the following video, it clearly shows the MASSIVE performance difference between the due and the mega when using a color LCD http://www.youtube.com/watch?v=JXcVw8dwxPw

  4. Maybe get a board with Ethernet already on-board? because i need the performance of the due, that is not an option =(

  5. Or why not Wifi? i like to make my projects as if they are a "commercial product" and since the wifi needs to be edited directly into the arduino sketch, i do not want to utilize that.
