David Mellis, one of the minds behind the Arduino platform, has released the blueprints to a cellphone that, with time and patience, anyone can build. The result is a basic cellphone that can make and receive calls, text messages, store names and numbers, and display the time. Currently at MITs Media Lab, Mellis has put all of the plans necessary to build and customize the phone up on Github, and also uploaded the circuit board plans to custom printer OSH Park, which will print three copies of the board for around $60. As for the casing, there are detailed instructions for a simple laser-cut plywood case, but several Media Lab members have crafted their own cases in a variety of shapes and hues, using milling, laser cutting, and 3D printing.
