## Summary

Hackaday editors Mike Szczys and Elliot Williams review a week of hardware hacks, including the legacy of RTL-SDR, 3D printed topology optimization, and Sega audio analysis. They discuss Ben Krasnow's discovery of optical brighteners in paper and detergent, and MD Fourier's project measuring the sonic differences between Sega Genesis models. The episode also covers a CNC painting robot, a ping-pong ball PID tuning demo, and the restoration of the 1958 FACOM 128 computer.
