## Summary

Hosts Tom Nardi and Kristina Panos discuss a range of hardware hacks, including Texas Instruments' changes to legacy op-amps like the NE5532 and OPA134, which create compatibility issues for designers. They explore creative projects such as loading Sega Genesis games from vinyl records using a Mega EverDrive Pro and a Pico 2, and projecting live ADS-B aircraft data onto a ceiling with an RTL-SDR. The episode also covers a DIY router build by Maya, the ethical concerns surrounding electronic shelf labels, and a ceramic circuit board prototype by Emily Velasco.
