## Summary

Hackaday editors Elliot Williams and Tom Nardi discuss the winners of the 555 Timer Contest, including Red Raksha's discrete wooden circuit sculpture and Eric Brandahl's ESP32-driven analog hybrid synthesizer. They highlight Riskables' open-source magnetic mechanical keyboard design that uses Hall effect sensors, and Colin O'Flynn's open-source Pico EMP tool for voltage glitching. The episode also covers a Star Trek Voyager tricorder prop by mangy dog, which required a complete redesign due to component obsolescence, and research into detecting malware via EM signatures.
