Here’s a brilliant way to make use of your old phone.
A lot of people probably have old Nokia phones lying around the house. In today’s smartphone age, these phones aren’t used much anymore because they lack the necessary features people use today. No WiFi, no mobile internet, no apps – just basic call and text functionalities.
While everyone’s snobbing these old Nokia phones these days, a guy named Daniel Davis thought of a way to make use of it.
There are plenty of options when choosing a smartwatch, but most of them are expensive. From Pebble, to Samsung Gear, to Apple Watch – there’s lots of options to choose from.
But what if you could build your own? Sounds exciting? That’s exactly what Davis did.
Davis used on old Nokia 110, tore it down, and picked up things he could use to build a smartwatch. Specifically, he took the tiny screen, vibrating motor, and speaker. He also used an Arduino Pro mini to control the display, and a bluetooth module to connect to the smartphone. In order have the smartwatch and Android phone get connected, he created an app using MIT’s app inventor. The Nokia smartwatch is powered by a 3.7V 1100mAh rechargeable battery.
Lastly, Davis printed the case of his Nokia smartwatch using a 3D printer. The product ended up being thick due to the components and battery, but it’s still geeky nonetheless.
While there are still more features to add, Davis kept it simple. However, those who wish to build upon the project are welcome to do so.
For those interested in trying this out, here’s the project page where Davis documented how he did it.
