Weathergotchi – an open-source climate Tamagotchi

Weathergotchi is an open-source, battery-powered climate data logger featuring a 1.54-inch e-paper display that records temperature and humidity readings over time with a week-long battery life. The project includes complete hardware designs (custom PCB and 3D-printed case), firmware for an ESP32-S3 microcontroller, and all documentation needed for building and customizing the device. All files—schematics, code, and CAD models—are publicly available on GitHub for makers to reproduce or modify.
