This is a prototype for a low power smartwatch, featuring a very low power e-paper screen and a small but mighty Wi-Fi enabled microcontroller. An included sensor including accelerometer, gyroscope, and magnometer tracks movement, gestures, and orientation. Optional extras would include a GPS or a Biosensor package.
This project came about because I wanted a smartwatch that was open source, could play music over Bluetooth, and that could last on a single charge for multiple days. These three aspects have guided the design to be simple, radio enabled, and low power. Some sacrifices have been made in the interest of power saving. The e-paper screen has a high display latency, blocking us from having high frame rates. The Wi-Fi and Bluetooth radios are usually disabled, only updating scarcely.
