Show HN: A working 3D model of an Enigma machine I watched the excellent Veritasium video [1] on the Enigma machine, and watched the full animation by Jared Owen [2], but was still a bit confused on how the inner mechanics of an Enigma machine work. I used Astra to build out the inner components through a combination of reference images, writing out hundreds of extremely detailed prompts, and building my own inspection tools to ensure that every part is sized and positioned in a historically accurate way. It's still a work in progress, but would love any feedback on the experience so far! 1. https://www.youtube.com/watch?v=JsBZOcqZerk 2. https://www.youtube.com/watch?v=ybkkiGtJmkM https://enigma.design September 29, 2026 at 10:45PM

Show HN: Low Poly Earth – The whole planet in 3D, built from OpenStreetMap data After seeing demos of Claude and GPT construct Manhattan and other city neighborhoods in 3D I was inspired to make something similar but for the entire Earth. It's a low poly version of Google Earth built using open street and elevation data as a native Apple silicon Mac app. It was built entirely using Codex and Claude Code and took about 80 days. https://lowpolyearth.pages.dev/ September 28, 2026 at 09:51PM

Show HN: Gat – Version large files with Git, without an LFS server Hi HN, I built Gat because I wanted one thing from data versioning: check out an old Git commit and recover the datasets, model weights, or assets that belong to it. It's basically a lock file for large files. I’d appreciate any feedback! https://ift.tt/xZOyWRv September 27, 2026 at 10:50PM
