Build Your Own Cell Phone With an Arduino

Instructables user "xiaobo__" has shared detailed instructions from which to build a fully functional cellular phone using an Arduino Uno microcontroller, a number of other off-the-shelf parts, and a 3D-printed plastic case.

The design actually seems pretty practical, even if a little clunky by today’s standards. Don’t give me the crazy eye when I say that I might actually take a crack at something like this.
