If youâre too old-school to dial your friends using the number pad on your fancy smartphone, you might want to check out this awesome rotary phone turned cell phone.
Messing around with an old rotary phone mechanism from years ago, YouTuber Mr. VoltÂ built the âRotary Cell Phoneâ â a mobile rotary station that actually works withoutÂ the need to hook it up to a landline.
Mr. Voltâs prototype is fully functional, which means you can actually make calls with it once you load the device with your SIM card. It also has a tiny screen and a bunch of other features: SMS, FM radio, Â a phone book (with enough memory for a single contact) and sleep mode. The phone also comes with its own stylus to make dialing easier.
To build this odd piece of tech, Mr. VoltÂ 3D-printed the case using ABS thermoplastic and also polished it with a sander; the metal parts were milled on an X-Carve CNC.
Inside, the phone packs an Adafruit Fona Feather to load SIM cards, a 96Ã64 pixel color OLED display, an 8-ohm 1W speaker and a 2,000 mAh LiPo battery. The inventive YouTuberÂ says he hasnât tested how long a fullÂ charge cycle lasts, but he speculates it should be âquite a while.â
Mr. Volt isnât the first DIY enthusiast to turn a rotary phone into a cell phone.
Weâve previously seen a frustrated developer build his own rotary cell phone when refused a landline in his new office. SparkFunÂ was also selling its own rotary cell station called the Port-O-Rotary, but itâs been retired from production since then.
