## Summary

Hackaday editors Elliot Williams and Tom Nardi discuss the rising cost of PCB fabrication due to supply chain issues, alongside several community hacks including Tag Tinker's work on hacking infrared electronic shelf labels and Joel Hawksley's e-ink home dashboard. They also cover CNC Dan's 3-axis camera slider, a home-built EDM machine for cutting metal gears, and Victor Frost's solar-powered local message board. The episode concludes with a deep dive into vanadium flow batteries for grid storage and the ongoing phase-out of leaded aviation gasoline (avgas).
