If you think about it, your smartphone has some really nifty bits lodged inside of it. There's a GPS chip in there, not to mention an accelerometer, and occasionally even (gasp!) a compass. The folks at SparkFun want to take all of those components and expose them to the outside world, and they intend to do it with a little something called the Electric Sheep. The Electric Sheep is a little Arduino-based breakout board that allows users to create their own homebrew accessories and hook them up to an Android device.source
