Nokia 1100 has been out of production for quite some time now and the once ubiquitous smartphone is now part of mobile history. However, a hacker has repurposed one into a smartwatch. Hacker Daniel Davis wanted a smartwatch, so he thought why not build one from the old Nokia 1100, he had lying around. The finished product is not pretty or light, but it tells time, can connect to a smartphone and gives calls and text notifications. What’s more Daniel has made a three part video explaining the process and how you can make one from an old phone.
Now the Nokia 1100 turned smartwatch won’t be winning any design awards or will be available for purchase. However, it is quite satisfying to see that even after so much time, age old Nokia devices still work. Furthermore, students and makers who want to build something new can try their hand at this. In this project the main things Daniel used is a Nokia 1100, a mini Arduino board, a Bluetooth module for connection and a 3.7v rechargeable battery, but as he explains you can swap parts as per your preference. You can see the entire project at tinkernut, where Daniel has listed all the parts as well as most of the code used in this project.
