Ryan Walker from Interrupt Labs, in collaboration with Protectli, has developed a new open-source uninterruptible power supply (UPS). This UPS, which operates on 12 18650 batteries, aims to provide a reliable power source for DC-powered devices during outages. Its open-source nature is a key. . GitHub - hacknus/open-source-ups: This is a simple, open source uninterruptible power supply (UPS), based around an STM32F405 and written in Rust. Cannot retrieve latest commit at this time. Their outlet strips built quickly get crowded with wall-warts, and why bother converting from DC to AC only to. . With an Espressif ESP32 providing a web server and NUT support and an RP2040 for control, this UPS is as open as they come. It provides the user with status information, such as battery voltage, AC line failure or backup operating mode.
