Show HN: Compass CNC – Open-source handheld CNC router (❄️ Score: 150+ in 4 days)
Link: https://readhacker.news/s/6y4ey
Comments: https://readhacker.news/c/6y4ey
Hey HN,
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.
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.
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 <$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.
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.
