## Summary

Hackaday editors Elliot Williams and Tom Nardi review the week's top hacks, including custom mechanical keyboards like Venability, salvaging antique LCD screens with FPGAs, and extracting bismuth from Pepto-Bismol. The episode features an interview with Ivan Grokhotkov of Espressif, who discusses the development of the ESP8266 and ESP32, the challenges of documentation in Chinese semiconductor companies, and hints at a future chip. They also cover DIY RC transmitters, retro-computing festivals, and the debate over teaching computational thinking versus specific coding languages.
