## Summary

Hackaday editors Elliot Williams and Dan Maloney discuss a variety of hardware hacks, including Kevin Linaw’s PCB-based stepper motors that levitate magnets, Robin Kearney’s Lego analog tide computer, and Andrea Favero’s minimalist Rubik's cube solver robot. They also cover Tim/CPLD CPU’s reverse engineering of a 2-wire addressable LED strip protocol, Yvonne Miranda’s small CNC machine for cutting aluminum, and the global citizen science data collected from the Hunga Tonga volcanic eruption.
