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.

Join Hackaday Editor-in-Chief Elliot Williams and Managing Editor Tom Nardi on another whirlwind tour of the week’s top stories, hacks, and projects. We start off with some breaking Linux security news, and then marvel over impeccably designed pieces of hardware ranging from a thrifty Z table for the K40 laser cutter to a powerful homebrew injection molding rig. The finer technical points of a USB device that only stores 4 bytes at a time will be discussed, and after taking an interactive tour through the internals of the 555 timer, we come away even more impressed by the iconic 50 year old chip. We’ll wrap things up by speculating wildly about all the bad things that can happen to floating solar panels, and then recite some poetry that you can compile into a functional computer program should you feel so inclined.

Join Hackaday Editor-in-Chief Elliot Williams and Managing Editor Tom Nardi as they bring you up to speed on the best stories and projects from the week. There’s some pretty unfortunate news for the physical media aficionados in the audience, but if you’re particularly keen on 50 year old integrated circuits, you’ll love hearing about the winners of the 555 Timer Contest. We’ll take a look at a singing circuit sculpture powered by the ESP32, extol the virtues of 3D printed switches, follow one hacker’s dream of building the ultimate Star Trek tricorder prop, and try to wrap our heads around how electronic devices can be jolted into submission. Stick around to the end as we take a close look at some extraordinary claims about sniffing out computer viruses, and wrap things up by wondering why everyone is trying to drive so far.
