Turn An Old Mobile Phone Into A Smartwatch With A Genuino

Have an ancient mobile phone sitting around? Tinkernut shows you how to make use of it by turning it into a smartwatch with a Genuino brain.

Genuino is known as Arduino in the US, but they are essentially the same.

Using a Nokia 1100, Tinkernut walks you through pulling apart the old phone, connecting it to the Arduino and setting up the software required to make this sucker work. By the end of the three-part series, you’ll have a bulky, but totally DIY watch that can connect to your phone to show you notifications and other small details. It sure ain’t pretty, but as a base for your own project, it’s one of the more clever DIY smartwatches we’ve seen. Head over to Tinkernut for the full guide.
