## Summary

Hosts Elliot Williams and Christina Panos discuss Amazon's decision to disable the auxiliary input on existing Alexa devices, noting the retroactive nature of the change. They cover several hacks, including Ray Triangle's ESP32-based DOOM console built into an antenna converter, Google Japan's conveyor belt keyboard concept, and Throthy Mumbo's FPGA-based VHS video game system. The episode also features Gareth Davies' ESP32 AM radio transmitter, Mihi's OpenSCAD-designed vertical garden, and articles on running a Matrix server and repairing headphones with OpenSCAD.
