## Summary

Hosts Elliot Williams and Al Williams review recent Hackaday posts, highlighting Denny’s microwave metal casting setup using silicon carbide crucibles and 3D printed molds, and Mano Arastita’s LT Spice simulation of 555 timer internals. They also discuss David Given’s reverse engineering of a cheap oscilloscope using the CH32F003 microcontroller, Michael Vutrich’s non-planar 3D printing experiments, and Nathan Butts’ citizen science radio astronomy presentation. The episode concludes with commentary on NASA’s budget cuts to the Chandra X-ray Observatory and the rising utility of affordable logic analyzers like the FX2 and SiPEED logic combo 8.
