Ep045: Raspberry Pi Bug, Rapidly Aging Vodka, Raining on the Cloud, & This Wasn't a Supercon Episode

Hackaday Podcast · 5 Dec 2019 · 1h 08m

What this episode covers

Hackaday editors Mike Szczys and Elliot Williams discuss the exhaustion of Raspberry Pi 4's HDMI signal interfering with its Wi-Fi, a power glitching attack on the ESP32 that compromises its encryption, and a hack that ages vodka in 30 minutes using an ultrasonic jewelry cleaner. They also cover Mike Harrison’s Supercon talk on LED consistency and gamma correction, the shutdown of Google Cloud Print and Best Buy’s IoT services, and the end-of-life of the Nest Revolve hub, highlighting the risks of cloud-dependent hardware.
