In a time when everyone is obsessed with making Bluetooth headsets smaller and lighter, SparkFun is bringing chunky back with two pounds of vintage style. A long, long time ago in the era of dial-tones and party-lines, there used to be something called a rotary phone. The original "click and drag," operating a rotary phone requires that you press the number you intend to dial and pull the dial back from there (Ask someone older than you). Now you can dial your friends the 'old school' way from your cell phone with our Bluetooth Portable Rotary Phone.
