## Summary

Hackaday editors Mike Szczys and Elliot Williams review a week of hardware hacks, including a cheap Lattice ECP5 FPGA dev board from Colorlight, a C64 touchpad by Jan Derogi, and tongue-actuated input devices. They discuss the MNT Reform open-source laptop by Lucas Hartman, a USB kill cord for laptop security, and using Audacity to analyze CNC machine chatter. The episode also covers gradient infill in 3D printing and data backup philosophies.
