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.

This week, Hackaday Editor-in-Chief Elliot Williams and Assignments Editor Kristina Panos fawn over a beautiful Italian split-flap clock that doesn’t come cheap, and another clock made of floppies that could be re-created for next to nothing. We’ll also sing the praises of solderless circuitry for prototyping and marvel over a filament dry box with enough sensors to control an entire house. The finer points of the ooh, sparkly-ness of diffraction gratings will be discussed, and by the end of the show, you’ll know what we each like in a microscope.

(And if you’re wondering about what my joke about not having Kristina on the show for 28 seconds, and all the professionalism, was about — we both forgot to press record the first time through and got ~15 minutes into the show before noticing. Yeah. But we had a good time the second time around anyway.)

Join Hackaday Editor-in-Chief Elliot Williams and Staff Writer Dan Maloney for this week’s podcast as we talk about Elliot’s “defection” to another podcast, the pros and cons of CNC builds, and making Nixie clocks better with more clicking. We’ll explore how citizen scientists are keeping a finger on the pulse of planet Earth, watch a 2D stepper go through its paces, and figure out how a minimalist addressable LED strip works. From solving a Rubik’s cube to answering the age-old question, “Does a watched pot boil?” — spoiler alert: if it’s well designed, yes — this episode has something for everyone.
