## Summary

Hosts Elliot Williams and Al Williams review recent Hackaday projects, highlighting Sentient Stardust's Image Map technique for multicolor FDM 3D printing, which reduces filament waste by varying layer perimeters. They discuss Kevin Kelm's elaborate 'Halcyon Dawn' starship simulator console, Project 326's tri-camera infrared video hack, and Cocono's portable X-band weather radar built from an RV dish and SDR. The episode also covers Trist's handling of loose Americium-241 sources at EMF hacker camp, Jessica Stanley's DIY flexible PCB workshops, and Tom Nardi's review of the ThingPwn firmware for IP cameras.
