Ep 270: A Cluster of Microcontrollers, a rocket engine from scratch, and a look inside Voyager

Name one other podcast where you can hear about heavy 3D-printed drones, DIY semiconductors, and using licorice to block laser beams. Throw in homebrew relays, a better mouse trap, and logic analyzers, and you'll certainly be talking about Elliot Williams and Al Williams on Hackaday Podcast 235. There's also contest news, thermoforming, and something that looks a little like 3D-printed Velcro. Elliot and Al also have their semi-annual argument about Vi vs. Emacs. Spoiler alert: they decided they both suck. Missed any of their picks? Check out the links on Hackaday, and as always, tell us what you think about this episode in the comments!

It might sound like a joke, but this week, Elliot Williams and Tom Nardi start things off by asking how you keep a Polish train from running. Like always, the answer appears to be a properly modulated radio signal. After a fiery tale about Elliot's burned beans, the discussion moves over to the adventure that is home CNC ownership, the final chapter in the saga of the Arecibo Telescope, and the unexpected longevity of Microsoft's Kinect. Then it's on to the proper way to cook a PCB, FFmpeg in the browser, and a wooden cyberdeck that's worth carrying around. Finally, they'll go over the next generation of diode laser engravers, and take a look back at the origins of the lowly breadboard.

This week, Editor-in-Chief Elliot Williams and Kristina Panos experimented with the old adage that brevity is the soul of wit. That's right; this week, they're all Quick Hacks, and that's to make room for a special series of interviews that Elliot recorded at CCCamp with the pillars of US hackerspace creation. This one's really special, do have a listen. We still made room for the news this week: India launched Chandrayaan-3, which combines an orbiter, lander, and rover all in one. Then it's on to the What's That Sound results show, and while Kristina did not get it right, she did correctly identify it as being used in Whitney Houston's "I Wanna Dance With Somebody", as did one of the guessers who identified it as the cowbell sound from a Roland 808. Then it's on to the (quick) hacks, where we alternated for once just to keep things interesting. This week, Elliot is into 3D printing a clay extruder and then printing pottery with that, z-direction conductive tape, and the humble dipole antenna. Kristina is more into cyberdecks for the young and old, a reusable plant monitor, and 3D printing some cool coasters.

Elliot is off at Chaos Communications Camp, and Tom is on vacation, leaving us with no podcast this week. But don't fret, Elliot is picking up a ton of interview material for next week's show. It's gonna be a good one!

Editor-in-Chief Elliot Williams and Al Williams don't always agree on the best text editor to use, but they do -- usually -- agree on what makes a great hack. This week, they found plenty of Hackaday posts to discuss, ranging from exotic eavesdropping on keyboards, oscilloscopes, and several posts of interest to anyone who wants to build good-looking prototypes. If you are like mechanics, you'll hear about an escapement-like mechanism and a Hobson's coupler. If you crave more traditional hacks, you can learn more about maximizing battery life and etching PCBs. In addition to a flurry of hacks, Elliot and Al also share their picks for the best original posts from Hackaday's staff. This week, we find out how Arya Voronova documents projects and hear what Tom Nardi thinks of his Beepy -- a ready-made display and Blackberry keyboard waiting for a Raspberry Pi. Did you miss anything? Check out the links.

This week, Editor-in-Chief Elliot Williams and Managing Editor Tom Nardi start things off by tackling a pair of science stories, one that may or may not change the world, and the other that hopes to help us understand the very fabric of the universe. Afterwards they get to the important stuff: the evolution of Game Boy Camera hacking, the finer points of 3D print orientation, and mixing up electrically conductive concrete at home. From there the conversation shifts to a couple of 486 Turbo buttons, a quick yoke recipe, and a very handsome open source vacuum pickup tool. Stick around until the end to hear about the folly of humanoid robots, and the latest operating system to get the Jenny List treatment.

This week, Editor-in-Chief Elliot Williams and Kristina Panos braved the slight cold and the high heat respectively to bring you the best hacks of the previous seven days. In the news this week: you've got a second and final chance to get your Supercon talk proposals in!  So get on that, because we need YOU to help make Supercon awesome. We can chalk up a win for Kristina on What's That Sound this week (finally!). Will you get it right? Will you get it exactly right? Time and Elliot's fancy dice will tell. Then it's on to the hacks, where we check out a cool RFID emulator e-paper badge, discuss whether a certain type of record player is better off as a cyberdeck, and look through the eye of a Gameboy-style camera for the Playdate console. From there we take a look at gutting and rooting voice assistants, a solenoid keyboard, and a beautifully rebuilt VR headset that now does AR as well. Finally we talk autonomous solar boats, lambast ChatGPT as the worst summer intern ever, and ponder what makes a thing count as Linux or not.

Summer's in full swing, and this week both Elliot and Dan had to sweat things out to get the podcast recorded. But the hacks were cool -- see what I did there? -- and provided much-needed relief. Join us as we listen in on the world of bats, look at a laser fit for a hackerspace, and learn how to make an array of magnets greater than -- or less than -- the sum of its parts. There'll be flying eggs, keyboards connected to cell phones, and everything good about 80s and 90s cable TV, as well as some of the bad stuff. And you won't want to miss Elliot putting Dan to shame with the super-size Quick Hacks, either, nor should you skip the Can't Miss sweep with a pair of great articles by Al Williams.
