LightInk: A DIY Smartwatch That Needs Charging Once a Year
Tech enthusiasts have introduced an unusual smartwatch called LightInk. This device is powered by solar panels and can run for up to 10 months on a mere 100 mAh battery. Unlike commercial models like Garmin, the solar module here is not hidden under the screen but is open and clearly visible. This is reported by Ixbt.com .
LightInk is not a finished product, but a DIY (Do-It-Yourself) project. It cannot be bought in stores: to assemble the device, the user must order printed circuit boards, use a 3D printer, and perform soldering. Therefore, the project is primarily aimed at experienced engineers and tech enthusiasts.
The device also stands out from modern smartwatches in terms of functionality. It is equipped with an E Ink display that is easily readable in sunlight and a lighting system for dark conditions. The watch also features LoRa technology for long-range communication, a GPS module, and a speaker.
To save energy, the developers have opted out of an accelerometer. At the current stage, there is no dedicated mobile app for LightInk, but the device's unique architecture makes it an interesting solution among open-source projects.
