Iron Engines Are Not Just From Our Wars

Join Hackaday Editor-in-Chief Elliot Williams and Managing Editor Tom Nardi as they look back on the best hacks and stories of the previous week. There's plenty in the news to talk about, though between faulty altimeters and the ongoing conflict in Ukraine, it isn't exactly of the positive variety. But things brighten up quickly as discussion moves on to 3D printed car wheels, a fantastically complex drum machine from 1958, a unique take on the seven-segment flip display, and a meticulously designed (and documented) coffee machine upgrade.

Somewhere in there a guy also recreates a rare German anti-air rocket launcher from WWII, but it's all in the name of history. We'll also tackle two very different forms of electric propulsion, from the massive wheeled batteries popping up in garages and driveways all over the world to high-efficiency thrusters for deep space missions.
