Updated Rotary Cellphone Uses FONA Feather, OLED display, LiPo for Power

This is a fantastic build from Mr. Volt spotted on YouTube! Check out the transparent window on the rear of the ‘prototype’ phone that displays the rotary gear mechanism – awesome!

An artifact from somewhere else.

A friend gave me a rotary phone mechanism years ago, and I finally got around to turning it into a working cell phone! It can call, text, play FM radio, and store one whole phone number.

-ABS (3D printed on Lulzbot Mini)
-Adafruit Fona Feather (Atmega 32u4 and SIMCOM800L)
-2000 mAh LiPo
-8 ohm 1W speaker

Adafruit Feather 32u4 FONA: This is the Adafruit Feather 32u4 FONA – our take on an ‘all-in-one’ Arduino-compatible + audio/sms/data capable cellular with built in USB and battery charging. Its an Adafruit Feather 32u4 with a FONA800 module, ready to rock! We have other boards and accessories in the Feather family, check’em out here. At the Feather 32u4’s heart is at ATmega32u4 clocked at 8 MHz and at 3.3V logic, a chip setup we’ve had tons of experience with as it’s the same as the Flora. This chip has 32K of flash and 2K of RAM, with built in USB so not only does it have a USB-to-Serial program & debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc. Read more.
