At the heart of the Chatter Smartphone I’m using a Raspberry Pi Model B+ to give the phone more brains than it was built with. A tiny WiFi dongle provides wireless network access, and a custom Python script (code below) running on startup provides all of the logic.
Wherever possible, I’ve used the original components and controls to interact with the phone. I also wanted to retain the ‘factory’ look of the phone, so I avoided adding a screen or any unnecessary buttons.
