## Summary

Hackaday editors Mike Szczys and Elliot Williams discuss the Open Source Hardware Association's recommendation to replace 'Master/Slave' terminology in SPI protocols with 'Controller/Peripheral' (COPI/CPOI). They then review several engineering hacks, including a variable-shape telescope mirror, a helicopter without a swashplate, and a vibratory wind generator. The episode concludes with a deep dive into repairing a MacBook GPU via micro-soldering, a heterodyne bat detector, and the discontinuation of the Segway.
