Show HN: Open-sourcing our text-to-CAD app https://ift.tt/9fUqRXQ

Show HN: Open-sourcing our text-to-CAD app Hey HN! I'm Zach from Adam ( https://adam.new/ ). We’re building an AI co-pilot for mechanical CAD software. As part of our broader research, we built a browser-based Text-to-CAD app ( https://ift.tt/blQ7sNo ) and are now open sourcing it. This is a React SPA with a Supabase backend. What it does: * Generates parametric 3D models from natural language descriptions, with support for both text prompts and image references * Outputs OpenSCAD code with automatically extracted parameters that surface as interactive sliders for instant dimension tweaking * Exports as .STL or .SCAD Under the hood: * Separate agents for conversation and code generation; simple parameter tweaks bypass AI entirely using deterministic regex-based updates * Runs fully in-browser by compiling OpenSCAD to WebAssembly and integrating Three.js with React Three Fiber for 3D rendering * Supports BOSL, BOSL2, MCAD libraries and custom font support (Geist) for text in models We’ve seen many developers trying to replicate this kind of functionality, so we’re releasing this to give the community a solid foundation to build on. Future improvements: * Expand geometry support - Move beyond CSG primitives to support curved surfaces, fillets, lofts, and constraint-driven modeling through CadQuery/Build123D * Better spatial context - UI for face/edge selection and viewport image integration to give LLMs spatial understanding * Enhanced capabilities - RAG on documentation and integration with more OpenSCAD libraries for features like proper threading You can clone the repo and run it locally! Contributions are welcome, and we’ll keep merging PRs as they come in. https://ift.tt/VeFnWXN September 5, 2025 at 10:39PM

Show HN: Swimming in Tech Debt https://ift.tt/pYsdbhT

Show HN: Swimming in Tech Debt This is the first half of my book, “Swimming in Tech Debt”. It is available at a pre-launch sale price of $0.99 ( https://ift.tt/P6bvpfk ). I have been working on it since January 2024. It is based on some posts in my blog, but expands on my ideas quite a bit. In September 2024, excerpts appeared in Gergely Orosz’s Pragmatic Engineer newsletter, which helped me get a lot of feedback that expanded the book from my initial idea. This half is about what I expected to do before that —- the rest of the book goes into team and CTO practices. https://ift.tt/C1B5xzo September 5, 2025 at 11:03AM

Show HN: A small browser game (PC only) built with Phaser 3 https://ift.tt/MEC5mVa

Show HN: A small browser game (PC only) built with Phaser 3 Hi HN! This is my first game — something I’ve always wanted to do. It’s a small browser game built with Phaser 3, React, and the phaser template ( https://ift.tt/qk8PlFt ). I made it in 2 days (like 8 hours in total real time) using gemini-cli. About 90% of the code was generated with AI, but I learned a lot by making fine tweaks. It only works on PC since it’s a typical WASD + R (reload) shooter. I’d love feedback on: - Gameplay (is it fun, too hard?) - Ideas for new features Thanks in advance! ps: I used cubes as a prototype, but now I kind of like them. Should I keep them or implement proper sprites? https://cubic-zombies.pages.dev/ September 5, 2025 at 02:44AM

Show HN: Quicknote.zip (Daily Micro Scratchpad) https://ift.tt/rqcdx8s

Show HN: Quicknote.zip (Daily Micro Scratchpad) I used to use https://doc.new when I needed to write quick scratchpad notes, but it takes like two seconds for Google Docs to be interactable, and ends up polluting my Drive with a bunch of "Untitled Docs". Lately I've used a bookmarklet that opens a fullpage contenteditable div which is instantaneous and worked for my needs. But I wanted persistence when I accidentally close the tab, and data-urls can't use localstorage, so I spun up quicknote.zip. It loads in the blink of an eye, works offline, and stores each day to localstorage. That's all it does, take it or leave it. https://quicknote.zip September 4, 2025 at 11:40PM

Show HN: Listgitfiles.sh – Fetch Raw GitHub File URLs with One Command https://ift.tt/xWyTS60

Show HN: Listgitfiles.sh – Fetch Raw GitHub File URLs with One Command I wrote this script to quickly retrieve raw file URLs from public GitHub repos. Added to my ~/.zshrc, it’s now a fast, reliable tool in my caveman workflow. Maybe you'll find use for it too! Have a great rest of your day, everyone! https://gist.github.com/rmtbb/d55638e758ad656eb40741dd60a39e5f September 4, 2025 at 03:58AM
