If you yearn for the days of rotary phones, help is at hand. A hardware maker known as Mr. Volt has combined the past and the present to make a fully functioning rotary cell phone.

    His prototype has the iconic dial on the front and offers six basic functions: it can make calls, store one phone number, text, tune into the radio, display system settings and go to sleep.

    “It runs on a fona feather, which is an Arduino* compatible board and has a little GSM modem built into it. It’s running regular Arduino C++ embedded goodness,” said Mr. Volt.

    There is also a bright red cancel switch and a memory function for saving numbers. There is also a clear window on the back that lets you peer inside and see internal dial in action.

    Calling appears to work just like it did with the previous models, those born a few decades ago probably remember the fun experience. Although this is the first rotary phone to have texting capabilities, it is extremely slow because you have to turn the dial for each letter.

    But to make it easier, the system does let you save particular words or phrases in memory to speed things up.

    There is also a systems function to see how much power is left and a sleep mode to shut it down when you’re not using the phone.

    And the entire thing is powered by an Adafruit microcomputer.(SD-Agencies)
