A DIY E-ink smartwatch called LightInk has been announced. It combines a solar panel, LoRa, GPS, and a speaker in a single wearable. The device is not a commercial product but comes from the DIY scene.
DIY smartwatch features solar panel and LoRa
The smartwatch uses an E Ink display with a backlight for readability in sunlight and darkness. It is powered by a 100mAh battery that can last up to 10 months on a single charge. To achieve this long battery life, the watch omits an accelerometer. Connectivity includes LoRa and GPS, and there is a built-in speaker.
The LightInk is a DIY project, not a commercially available product. It is designed for hobbyists and makers who want to build their own smartwatch.
The project is hosted on GitHub. The developer has not confirmed plans for a companion app or any commercial release.
