## Summary

Hackaday editors Mike Szczys and Elliot Williams discuss the Prusa 'Buddy' board controversy, where Prusa Research locks firmware flashing behind a physical 'appendix' trace to prevent safety hazards, sparking debate in the maker community. They also cover Paul Bryson’s technique of using flexible PCBs for complex board rework, Nick Poole’s tips on building enclosures from PCB material, and the world's largest grid-scale battery backup at the Hornsdale Power Reserve.
