## Summary

Hackaday editors Mike Szczys and Elliot Williams discuss a range of hardware hacks, including Ben Heck's logic-chip solution for WS2812 Neopixel timing and Wayne Holder's ATtiny10 firmware alternative. They analyze the accuracy of temperature-compensated real-time clock chips like the DS3231 and PCF2129, and highlight Fran Pirnos's DIY 3D CT scanner built from a dental X-ray tube. The episode also covers the end of Airbus A380 production, skepticism regarding DSRC vehicle-to-vehicle communication, and the growing crisis of global e-waste.
