## Summary

Hackaday editors Mike Szczys and Elliot Williams review the week's hacker projects, including a 12-channel LED spectrum mixer, an omni-wheeled pen plotter, and a Turing-complete system built from hospital nurse call devices. They analyze a paper claiming to fingerprint 3D printers, arguing the method is flawed because it ignores filament variability, and discuss NASA's engineering philosophy of over-specifying hardware for long mission lives, citing the Opportunity rover and Voyager probes. The episode also features a jargon quiz on 'astrictive robotic prehension' and a new '$50 Ham' column.
