Ep 158: Phased Array Physics, CRTs Two Ways, A Micro Microcontroller, and a Surgically Implanted Red Herring
Hackaday editors Elliot Williams and Dan Maloney review community projects including a tiny BJ microcontroller, a CRT transplant from a fish finder, and a water-based phased array sonar demo. They discuss the engineering challenges of sealing soil moisture sensors against corrosion and analyze how synthetic aperture radar satellites can inadvertently expose military radar sites. The episode also covers a Hot Wheels PC case mod, exam cheating scandals, and crowdsourced soldering war stories.
