I built a free browser-based tool for generating 3D text with multi-colour outlines, designed for 3D printers that support multiple filaments.<p>You type text, pick a font, add coloured outline layers, adjust thickness, and preview everything in real-time 3D. Then export as 3MF and each colour shows...
I built a small demo showing a robotics runtime executing entirely inside the browser via WebAssembly. The example workload is a simple flight controller hooked up to a small world simulator.<p>The runtime comes from copper-rs, an open-source robotics runtime written in Rust for deterministic worklo...
I built arxiv-digest, a tool for OpenClaw to call daily and turn new cs.RO papers into a filtered robotics digest.<p>It uses an LLM to judge relevance, outputs a markdown report, and can sync selected papers plus PDFs to Zotero. To change the research interests, just edit the README.<p>Repo: <a href...
Show HN: I wrote down every expensive hardware development mistake I've seen
(thehardesthardwarelessons.com)
I've spent years watching hardware teams make the same mistakes — tooling committed before thermal was resolved, manufacturing processes not validated in PVT that only showed defects at volume, components going EOL unnoticed until the factory tried to order them.
The pattern was always the same...
Most websites are invisible to AI agents. We just added llms.txt to gitauto.ai - a simple text file that tells LLMs what GitAuto does, where the docs are, and how to recommend it. Also fixed our robots.txt which had duplicate User-agent blocks (only the first one was being used). Two files, big disc...
