Show HN: Oasis – an open-source, 3D-printed smart terrarium See the website for a demo video: https://ift.tt/mRfBE2u This project is an enclosure for growing plants. Features include: - high-power LED lighting - a built-in water tank and mister - fans for airflow - temperature and humidity sensing - wi-fi connectivity and a web-based interface for control and monitoring (see https://ift.tt/itSRJfE) The entire project is open-source: - electronics: designed in KiCad - 3D models: designed in CadQuery - software: written in Rust I initially started this project during COVID and built a working prototype using a Raspberry Pi and off-the-shelf parts. The first prototype worked, but was pretty rough. Several months ago, I picked up the project again and began a complete re-design. After two rounds of circuit board design and countless iterations of the 3D-printed parts, I'm finally happy with the results. Along the way I learned a lot about electronics design and fabrication, 3D modeling, and Rust. Happy to answer any questions - thanks for checking it out!
