Melting Metal in the Microwave, Unlocking Car Brakes and Washing Machines, and a Series of Tubes

Wait, what? Is it time for the podcast again? Seems like only yesterday that Dan joined Elliot for the weekly rundown of the choicest hacks for the last 1/52 of a year. but here we are. We had quite a bit of news to talk about, including the winners of the Component Abuse Challenge -- warning, some components were actually abused for this challenge. They're also a trillion pages deep over at the Internet Archive, a milestone that seems worth celebrating. As for projects, both of us kicked things off with "Right to repair"-adjacent topics, first with a washing machine that gave up its secrets with IR and then with a car that refused to let its owner fix the brakes. We heated things up with a microwave foundry capable of melting cast iron -- watch your toes! -- and looked at a tiny ESP32 dev board with ludicrously small components.  We saw surveyors go to war, watched a Lego sorting machine go through its paces, and learned about radar by spinning up a sonar set from first principles. Finally, we wrapped things up with another Al Williams signature "Can't Miss Articles" section, with his deep dive into the fun hackers can have with the now-deprecated US penny, and his nostalgic look at pneumatic tube systems.
