## Summary

Hackaday editors Elliot Williams and Mike Szczys discuss a week of hardware hacks, including a Roku TV rooted to drive an Ambilight-style LED setup, a 4-axis 3D-printed camera motion rig using slip rings and ESP32s, and James Bruton’s innovative spherical omniwheel robot. They also cover a VGA-to-composite glitching synth, a scroll saw blade-tracking system using hard drive platters, and a 6-DOF robot arm for non-planar 3D printing. The episode concludes with a community discussion on how the global chip shortage is forcing redesigns and compounding supply chain issues for makers and small businesses.
