Ever wanted a phone that doesn’t just look like a small black box straight out of a Foxconn factory? Learn how to make your own fully functional GSM phone capable of voice, SMS and data. All you’ll need is a SIM card, an Arduino, a few cheap hardware components and a soldering iron.

If you’re thinking about making your own Internet Of Things connected devices, we’ll be talking about how to embed this GSM functionality in your own non-phone hardware devices, just like Amazon does with Whispernet in the Kindle. For the right application it’s a great alternative to Wifi, Zigbee or Bluetooth connectivity.

Creating and debugging code to glue together a keypad, screen and GSM modem in 32kb of RAM is surprisingly fiddly. We’ll talk about what we learned writing the realtime state-machine that acts as an operating system.

Are there ever going to be slides for this? Or maybe a parts list?
