## Summary

Hackaday editors Mike Szczys and Elliot Williams review several hardware hacks, including an acoustic camera by John Duffy, Ryan O, and Sarah Park that uses an FPGA for real-time sound localization, and a flightless pneumatic drone by Jose Manuel Hermano Barrero (Pateo) featuring 6 hand-machined aluminum engines. They also discuss a TEA laser build by Les that utilizes hex standoffs for precise alignment, a wind turbine by Fab with pitch adjustment, and a Spectra coexistence attack on Broadcom BCM4339 chips by Yiska Klassen and Francesco Gringoli. The episode concludes with a discussion on overhead wire-powered trucks and the virtual Hackaday Prize.
