## Summary

Hackaday editors Mike Szczys and Elliot Williams discuss several hardware hacks, including Elliot printing 3D-printed face shields for a local doctor and the community effort to produce open-source ventilators from Medtronic's released designs. They analyze a hack that repurposes a vintage Nixie tube frequency counter using I2C expanders, and Jan Rozick's method for creating 3D-printed solder paste stencils. The episode also covers a teardown of a radar-based motion sensor, a fast-heating soldering iron with machine learning, and Tim Berners-Lee's Solid decentralized internet platform.
