[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: Interactive Bash tutorial that runs in the browser I wrote a tutorial on how to create Bash scripts, where the command line interface runs entirely in the browser using v86 (<a href="https:&#x2F;&#x2F;github.com&#x2F;copy&#x2F;v86">https:&#x2F;&#x2F;github.com&#x2F;copy&#x2F;v86</a>), and the code editor uses Monaco.

[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.

[Other] Show HN: UML is dead – so I'm building the tool to revive it Hi HN,<p>UML diagrams were meant to standardise system design, but they’ve become outdated — slow to build, hard to change, and rarely used in practice. Most tools feel clunky, and diagrams often go stale fast.<p>I’m building RapidChart, a tool to bring diagramming back to life — fast, flexible, and developer-first.<p>What makes it different:<p>Cursor-style interface for rapid diagram creation<p>Fully customisable and exportable<p>AI-assisted (works with GPT-4, Claude, etc.)<p>100% free<p>This began as part of my research at Imperial College London, and I’d really value your feedback.<p>Here’s the link: <a href="https:&#x2F;&#x2F;www.rapidcharts.ai" rel="nofollow">https:&#x2F;&#x2F;www.rapidcharts.ai</a><p>Thanks!
