[Other] Show HN: MCP server for Blender that builds 3D scenes via natural language Hi HN!<p>I built a custom MCP (Model Context Protocol) server that connects Blender to LLMs like ChatGPT, Claude, and any other llm supporting tool calling and mcps, enabling the AI to understand and control 3D scenes using natural language.<p>You can describe an entire environment like:<p>&gt; “Create a small village with 5 huts arranged around a central bonfire, add a river flowing on the left, place a wooden bridge across it, and scatter trees randomly.”<p>And the system parses that, reasons about the scene, and builds it inside Blender — no manual modeling or scripting needed.<p>What it can do: - Generate multi-object scenes like villages, landscapes, from a single prompt - Understand spatial relations — e.g., “place the bridge over the river” or “add trees behind the huts” - Create camera animations and lighting setups: “orbit around the scene at sunset lighting” - Respond to iterative changes like: “replace all huts with stone houses” or “make the river narrower” - Maintain object hierarchy and labels for later editing<p>Tech Stack: - Blender Python scripting - Node.js server running MCP - LLM backend (OpenAI &#x2F; Claude, easily swappable)<p>Demo: <a href="https:&#x2F;&#x2F;blender-mcp-psi.vercel.app&#x2F;" rel="nofollow">https:&#x2F;&#x2F;blender-mcp-psi.vercel.app&#x2F;</a><p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;pranav-deshmukh&#x2F;blender-mcp-demo&#x2F;">https:&#x2F;&#x2F;github.com&#x2F;pranav-deshmukh&#x2F;blender-mcp-demo&#x2F;</a><p>Curious to hear thoughts from folks in 3D tooling, AI-assisted design, or dev interface design. Would you find this useful as a Blender plugin? I’m open to expanding it!<p>Please try it and give it a star on github

[Other] Show HN: Context42 – capture your coding style from across your projects Show HN: Context42 - AI-powered style guide generator for your codebase<p>Hey HN,<p>I&#x27;ve been building Context42 to solve a problem that&#x27;s been bugging me: getting AI to write code like me, and helping disseminate coding best practices.<p>The core insight is simple - your existing code is already your best style guide. Instead of debating tabs vs spaces or where to put your curly braces, Context42 analyzes your actual codebase and generates comprehensive style documentation using Google&#x27;s Gemini AI.<p>Here&#x27;s what makes it special:<p>1. *Language-aware analysis* - It groups files by language and generates specific style guides for each. Your TypeScript patterns won&#x27;t bleed into your Python conventions.<p>2. *Dependency-smart processing* - It analyzes child directories before parents, building up context as it goes. This means it understands your module structure and can identify patterns that emerge across your architecture.<p>3. *Built for real codebases* - With configurable concurrency, resume capability, and automatic cleanup, it&#x27;s designed to handle everything from small projects to massive monorepos. The terminal UI (built with Ink&#x2F;React) gives you real-time progress on what&#x27;s happening.<p>4. *Pragmatic over prescriptive* - Instead of enforcing arbitrary rules, it documents what you&#x27;re already doing. This makes it easier to onboard new developers and maintain consistency without religious debates.<p>The technical approach is interesting too - it uses a worker pool pattern with abort controllers for graceful shutdown, SQLite for persistence (so you can resume failed runs), and a file registry system that guarantees cleanup even on crashes.<p>I built this because I believe the best documentation is the kind that reflects reality, not aspirations. Your code style isn&#x27;t what you think it should be - it&#x27;s what it actually is. And that&#x27;s worth documenting.<p>You can check it out at: <a href="https:&#x2F;&#x2F;github.com&#x2F;zenbase-ai&#x2F;context42">https:&#x2F;&#x2F;github.com&#x2F;zenbase-ai&#x2F;context42</a><p>Would love to hear your thoughts, especially if you&#x27;ve tackled similar problems in your teams. What&#x27;s worked for you in maintaining code consistency at scale?

[Other] Show HN: Compass CNC – Open-source handheld CNC router Hey HN,<p>I am Cam, and for the past two years I have been working on Compass, an open-source handheld CNC router that brings computer precision to woodworking while keeping the user directly involved in the process.<p>The idea started as my senior design project at UC Berkeley, with the goal of making a more approachable CNC machine—standard CNC machines are expensive, bulky, and remove you from the tactile “maker” experience. Compass solves that by combining a handheld router with real-time robotic assistance. You move the router roughly along a design path, and Compass uses four optical flow sensors (like in computer mice) and a 3-axis motion system to auto-correct for precision cuts.<p>What is different about Compass: - Open source: All plans, firmware, and CAD files are available on GitHub. - Affordable: The DIY build costs ~$600 in parts, and I am selling kits for &lt;$800. - No external markers: The sensing technology allows for positioning without external markers, so no setup or consumables required. - Portable: Fits in a backpack and is not limited by a fixed work envelope.<p>We recently completed our first beta program and have just launched V1 kits for pre-order. You can find more info and the launch video at the listed URL.<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;camchaney&#x2F;handheld-cnc">https:&#x2F;&#x2F;github.com&#x2F;camchaney&#x2F;handheld-cnc</a>

[Other] Show HN: Molab, a cloud-hosted Marimo notebook workspace We launched marimo [1], an open-source reactive Python notebook, last year on HackerNews. Today, the most popular recent feature request in Google Colab’s issue tracker asks for marimo support in Colab [2].<p>Rather than try to convince Google to replace their notebook with marimo, we decided to just build our own cloud-hosted notebook service instead. We&#x27;re calling this molab (mo for marimo), and we&#x27;re launching it today.<p>You can try it at <a href="https:&#x2F;&#x2F;molab.marimo.io" rel="nofollow">https:&#x2F;&#x2F;molab.marimo.io</a><p>Some features:<p>- Persistent storage<p>- Link sharing (notebooks are public but undiscoverable, like secret GitHub Gists)<p>- Download notebooks to your machine, reuse them as Python scripts or apps<p>- Upload local notebooks to the cloud from our CLI (coming soon)<p>- Real-time collaboration (coming soon)<p>- Configure computational resources to obtain more CPU or GPU (coming soon)<p>marimo is a modern notebook for modern data workflows; we also built molab on a modern tech stack:<p>- Notebook dependencies are managed by uv, enabling lighting-fast package installation (thanks to uv’s cache and more generally its performant implementation). uv makes it easy to run molab notebooks locally, too: uvx marimo edit &lt;notebook-url&gt; brings the notebook down to your machine.<p>- Persistent storage is powered by R2, Cloudflare’s zero-egress object store.<p>- We use Pydantic logfire to monitor our deployment.<p>- While our implementation is agnostic to the compute backend (stay tuned!), we’re currently running on Modal for fast startups (not to mention a slick developer experience). Modal sandboxes make it easy for us define containers at runtime, containing notebook code and their dependencies. (Shout out to Eric Zhang from Modal for helping us get started.)<p>molab is free to use, as long as usage is reasonable. Our goal is to make is as easy as possible for our community to use marimo notebooks.<p>Finally, learn more at our announcement blog: <a href="https:&#x2F;&#x2F;marimo.io&#x2F;blog&#x2F;announcing-molab" rel="nofollow">https:&#x2F;&#x2F;marimo.io&#x2F;blog&#x2F;announcing-molab</a><p>If this interests you, please give molab a shot and please share feedback — here or on Discord (<a href="https:&#x2F;&#x2F;marimo.io&#x2F;discord" rel="nofollow">https:&#x2F;&#x2F;marimo.io&#x2F;discord</a>).<p>P.S.
