Weathergotchi – an open-source climate Tamagotchi
Weathergotchi is an open-source, low-power climate data logger that uses an e-paper display to track temperature and humidity. The project provides all necessary hardware schematics, firmware, and 3D-printing files for users to build their own device.
Why it matters
It promotes open-source hardware and DIY environmental monitoring, making climate data collection accessible to hobbyists.
About This project is an open-source, battery-powered temperature and humidity data logger with an always-on e-paper display. It records ambient conditions over time, stores readings in non-volatile memory, and displays current data along with a history graph. The device is designed for low power consumption, over 1 week of operation on a small Li‑Po battery.
The entire project is open source, including hardware schematics, PCB layout, firmware, and enclosure CAD files. A detailed build video is available on YouTube: E-Paper Climate Logger .
