Weathergotchi – an open-source climate Tamagotchi

Weathergotchi is an open-source, battery-powered data logger that measures temperature and humidity and displays current readings on a 1.54-inch e-paper display. It uses an ESP32-S3 with deep sleep, logs data to external EEPROM, and is designed for more than a week of operation on a small Li-Po battery. The project includes hardware designs, firmware, enclosure CAD files, and a build guide, with a YouTube video detailing assembly.
