## Summary

Hackaday editors Elliot Williams and Tom Nardi discuss a German wheelchair manufacturer's controversial subscription model for app features, a community effort to document a poorly supported Hell Tech ESP32 dev board, and a review of Eric Hunting's comprehensive guide to mechanical building systems. They also cover techniques for reverse-engineering hex dumps in legacy devices, the use of scarf joints in 3D printing slicers, and Arya's new column on PCB design reviews and KiCad automation.
