CNX Software ☛ LightInk – An ESP32-based, solar-powered E-ink smartwatch with up to 10 months of battery life
Daniel Ansorregui has developed LightInk, an open-source solar-powered E-ink watch inspired by 90s solar digital watches. It features a 1.54-inch e-paper display and supports Wi-Fi, Bluetooth, LoRa, and GPS, running on a 100mAh battery. The project integrates a custom low-quiescent-power design using a TPS63900 buck-boost converter, capacitive-touch input, and deep-sleep-driven firmware, along with ultra-fast partial e-ink updates (<1 ms active time) and precise RTC timekeeping with drift calibration.

CNX Software ☛ KernelUNO – A lightweight OS for Arduino UNO with a Linux-like shell
KernelUNO is an Arduino sketch with 546 lines of code that provides a lightweight OS for the Arduino UNO with a Linux-like shell offering commands such as ls, df, uname, and so on. All you need is an Arduino UNO R3 or a compatible board with a Microchip ATmega328P microcontroller, a USB cable for programming, and optionally a few LEDs and resistors for testing the gpio command in the terminal.
