## Summary

Hackaday editors Mike Szczys and Elliot Williams review a week of hardware hacks, including Max Kay's ultra-low power ESP32 handheld computer and a project running support vector machine classification on an ATtiny85. They discuss Nathan's massive basement UPS built from 96 scavenged lead-acid batteries and Maurice McKay's Z-wave retrofit of a Mocha Master coffee maker. The episode also covers 3D-printed press brake tools, the history of natural nuclear reactors, and the ubiquity of barcodes.
