Engineer Justine Haupt built this novel cellphone that uses a rotary dial instead of a touchscreen to dial numbers. She used an old classic trimline phone for the dial, and put everthing together using an Arduino board and Adafruit parts. If you’re wondering why she did it, here’s what she wrote:
Why a rotary cellphone? Because in a finicky, annoying, touchscreen world of hyperconnected people using phones they have no control over or understanding of, I wanted something that would be entirely mine, personal, and absolutely tactile, while also giving me an excuse for not texting. …So it’s not just a show-and-tell piece… My intent is to use it as my primary phone. It fits in a pocket.; It’s reasonably compact; calling the people I most often call is faster than with my old phone, and the battery lasts almost 24 hours.
