## Summary

Hosts Elliot Williams and Kristina Panos review a week of hardware hacks, including Leo Goldstein’s 6-DOF robot arm built with Toolbox Robotics parts and Clipper motion planning, and a DIY ribbon microphone constructed from an Airwaves gum wrapper foil. They discuss CNC Kitchen’s findings on 3D printing 'brick layer' perimeters for Z-axis strength, Panda Design’s virtual log modifier for wood-grain textures, and the rapid depletion of new old stock Blackberry keyboards driving a new open-source ecosystem.
