## Summary

Hackaday editors Mike Szczys and Elliot Williams discuss a new Raspberry Pi 4 revision fixing USB-C power issues, the TasmoAdmin tool for flashing Sonoff devices, and Bitluni’s advanced ESP32 hacks. They also analyze James Bruton’s self-balancing robot, a DIY Ryobi battery power station, and the controversy surrounding Sonos disabling older speakers to drive upgrades.
