Chronio - Low power Arduino based (smart)watch

Chronio is an Arduino-based 3D-printed Watch. By not including fancy Wifi and BLE connectivity, it gets several months of run time out of a 160mAh button cell. The display is an always-on 96x96 pixel Sharp Memory LCD. If telling the time is not enough, you can play a simplified version of Flappy Bird on it. DIY watches often consist of a pcb and screen wrapped in duct tape. I wanted to change that by designing a 3D-printed case. It is closely oriented on the Pebble Time. Currently I am testing the battery life. The Third and final PCB version is finished. I will update the project logs over time.”
