I was thinking the exact same thing, only I started on the other end, designing the perfect pendant. You, wisely, started by actually interfacing Arduino with EMC. I definitely look forward to reading your adventures.
have you considered using the new Arduino Mega 2560 as a starting point to make sure you have sufficient horsepower going forward? I would be happy to contribute if you want to make this a group project. Good luck!
