## Summary

Hackaday editors Elliot Williams and Mike Szczys discuss a mix of hardware hacks, including Huygens Optics' micro-etching of glass with hydrofluoric acid, a debunked laser deflection project, and Caribou Labs' SDR hat for Raspberry Pi. They also cover a teardown of a Xiaomi wireless charger, the potential of graphene in hard drive manufacturing, and a teardown of a vintage France Crystal metronome.
