## Summary

Hackaday editors Mike Szczys and Elliot Williams discuss a variety of hardware hacks, including a 1993 PowerBook 165 C retrofitted with a 2014 Mac Mini, and a servo-driven Kalimba. They also cover techniques for detecting counterfeit chips, such as using acetone to remove 'black topping,' and explore the history of resistor color codes. The episode concludes with a look at Raspberry Pi 4 capabilities for video game emulation.
