## Summary

Hackaday editors Elliot Williams and Kristina Panos review the week's hacks, starting with the extended 2024 Supercon SAO contest deadline and a 'What's That Sound?' segment. They discuss David Malawi's demonstration of 3D print warping caused by shrinkage forces, Wenting Jiong's liquid powder display, and Vance Vagel's ESP32-based ham radio module. The episode also covers Linus Atkinson's live coding on the Commodore 64, Stephen Walters' analysis of CRTs for retro gaming, and various keyboard projects including the Arjiboy FX and Canacord Plus.
