Hi HN, This is my attempt to fix groggy mornings by lowering my bedroom CO2 from 1700 ppm to ~900 ppm. I designed a simple, 3D-printed fan duct that directs air under the door to improve air circulation. A note on the design process: I used CadQuery, a Python library for creating parametric 3D models. I didn't know tools like this existed and highly recommend it if you can program; it turned out to be more convenient than manually iterating on prototypes in a GUI. The project is open source and the post explains the full build. Happy to answer any questions.

Hi HN, I’m sharing a small open-source project I’ve been working on: a native C++ ballistic solver that computes launch angles to intercept moving targets in real time, under gravity and air drag. Instead of relying on vacuum assumptions, closed-form equations, or lookup tables, the solver formulates the intercept as a nonlinear problem and solves it numerically using time integration and iterative methods. The motivation came from game and simulation scenarios where simpler approaches tend to break down: - moving targets - strongly curved trajectories due to drag - real-time constraints The…
