Designer to build a cell phone

If you like messing with Arduino contacts, then the new designer from MIT engineers will also like it. This is a self-assembly kit for a mobile phone. The device works with SIM-cards of any mobile operator.

The designer uses GSM-module SM5100B manufactured by SparkFun Electronics and a printed circuit board from Adafruit Industries. The 1.8 inch (160x128) color display can be inexpensively bought in a Chinese store. In this configuration, all the details will cost about $ 150.

In addition, the designer is compatible with standard parts, so you can customize it for the desired tasks. For example, connect a temperature sensor or other sensors in an apartment or car, by purchasing additional parts for the Arduino board.

The project has been under development for almost a year; you can follow the development in the author's photo album . As you can see, the last few months he spent on the project of a nice plastic case, which can be printed on a cheap 3D-printer MakerBot Replicator.





There are other options: for example, a stylish wooden case.



Naturally, the 3D model of the case, the keyboard and other details will be laid out in open access for printing by everyone, just as the design of the printed circuit board and the source code of the firmware are now published. The current version supports dialing from a numeric keypad and voice communication. Over time, the author promises to develop the ability to send SMS.
