Ep 217: The Unintentional Space and 3D Printing Episode
Hackaday Editors Elliot Williams and Tom Nardi definitely didn't plan on devoting most of this episode to 3D printing and space stories, but let's be honest, it was bound to happen sooner or later. After an update on the Hackaday Prize, the discussion moves on to a pair of troubled spacecraft and the challenges of exploring the final frontier. From there you'll hear about a chocolate 3D printer we've had our eyes on for years, the tools you should have next to your own (non-chocolate) 3D printer, and a bit of contemplation of what it really means to design for 3D printing versus traditional manufacturing methods. But it's not all plastic fantastic -- by the end of the episode you'll also hear about some particularly bold high-altitude aviators and the surprisingly short time we have left with the humble barcode.

Ep 216: FETs, Fax, and Electrochemical Fab
In this week's podcast, non-brothers Elliot Williams and Al Williams talk about our favorite hacks of the week. Elliot's got analog on the brain, courtesy of the ongoing Op Amp Contest, and Al is all about the retrocomputers, from a thrift-store treasure to an old, but still incredibly serviceable, voice synthesizer. Both agree that they love clever uses of mechanical parts and that nobody should fear the FET.

Ep 215: Autonomous Race Car, Espresso Robot, and Vintage Computers
It's podcast time again, and this time around Elliot and Dan took a grand tour through the week's best and brightest hacks. We checked out an old-school analog cell phone that went digital with style, dug into a washing machine's API, and figured out how to melt metal in the microwave -- the right way. Does coffee taste better when it's made by a robot? Of course it does! Can you get a chatbot to spill its guts? You can, if you know how to sweet talk it. Let's play Asteroids on an analog oscilloscope, spoof facial recognition with knitting, and feel the need for speed with an AI-controlled model race car. And was VCF East worth the wait? According to Tom Nardi, that's a resounding "Yes!" Check out the links over on Hackaday and tell us what you think about this episode in the comments!

Ep 214: Jet Engine Hair Dryer, Comic Sans Type Balls, and Belief in Graphene
This week, Editor-in-Chief Elliot Williams and Contributor Emeritus Kristina Panos gushed about all the best hacks of the previous week. But first, a contest! That's right -- hot on the heels of the Low Power Challenge comes the Op Amp Challenge, sponsored by Digi-Key. You have between now and June 6th to dip your toes into the warm waters of analog and show us what you've got. Will it be a musical hack? Will you seek high analog precision? We can't wait to see. Kristina definitely did not get What's That Sound this week, which honestly reminded her of a cartoon character getting a piano dropped on them, except the sounds were in reverse order. Then it's on to the hacks, beginning with a way to make an IBM Selectric typewriter use Comic Sans, a project that's sure to make you a believer in graphene, and a miniature MNT for every (cargo) pocket. From there we take a look at a really cool indicator from a 1960s RAF aeroplane and investigate why your multimeter might be lying to you. Finally, we discuss the gargantuan task of building an AR system to rival Google Glass, and the merits of taking a lot of pictures as you go about your hacks. Head on over to Hackaday to check out the links!

Ep 213: Not your Grandfather's Grandfather Clock, the Engineering Behind Art, Hydrogen Powered Flight
Join Hackaday Editors Elliot Williams and Tom Nardi as they review some of their favorite hacks and projects of the past week. The episode starts with a discussion about the recently announced Artemis II crew, and how their mission compares to the Apollo program of the 1960s and 70s. From there, the pair theorize as to why Amazon's family of Echo devices have managed to evade eager hardware hackers, take a look at a very impressive SMD soldering jig created with some fascinating OpenSCAD code, marvel at the intersection of art and electronic design, and wonder aloud where all the cheap motorized satellite dishes are hiding. Stick around for some questionable PCB design ideas, a Raspberry Pi expansion that can read your mind, and the first flight of a (semi) hydrogen-powered aircraft. Check out the links over at Hackaday.

Ep 212: Staring through ICs, Reading Bloom Filters, and Repairing, Reworking, and Reballing
It was quite the cornucopia of goodness this week as Elliot and Dan sat down to hash over the week in hardware hacking. We started with the exciting news that the Hackaday Prize is back -- already? -- for the tenth year running! The first round, Re-Engineering Education, is underway now, and we're already seeing some cool entries come in. The Prize was announced at Hackday Berlin, about which Elliot waxed a bit too. Speaking of wax, if you're looking to waterproof your circuits, that's just one of many coatings you might try. If you're diagnosing a problem with a chip, a cheap camera can give your microscope IR vision. Then again, you might just use your Mark I peepers to decode a ROM. Is your FDM filament on the wrong spool? We've got an all-mechanical solution for that. We'll talk about tools of the camera operator's trade, the right to repair in Europe, Korean-style toasty toes, BGA basics, and learn just what the heck a Bloom filter is.

Ep 211: Pocket Sundial, Origami Llama, PCB Spacemouse
This week, Editor-in-Chief Elliot Williams and Contributor Emeritus Kristina Panos chewed the fat about the coolest hacks of the previous week. But first, a bit of news -- our Low Power Challenge fizzled out this week, and boy did we have a lot of entries at the last minute. We love to see it though, and we're going to get judging done ASAP. Don't forget, this weekend is Hackaday Berlin! Livestreaming for this one may be iffy, but we'll have the talks up for you eventually, so don't fret too much if you can't make it in the flesh this time. Kristina definitely got What's That Sound this week, but her answer will of course be bleeped out. Then it's on to the hacks, beginning with a 6DoF controller that does everything in interesting ways and a printed shredder that eats like a goat. From there they cover bolt dispensers, coffee grinders with Bluetooth weighing, camera calibration, and a 50-pen plotter that's definitely a hack. Finally, we discuss the virtues of physicality when it comes to SIM cards and recorded music.

Ep 210: Living in the Future, Flipper Mayhem, and Samsung Moons the World
Editor-in-Chief Elliot Williams is joined this week by newly minted Development Editor (and definitely not brother) Al Williams to bring you the weekly highlights from our little corner of the Internet. Between the rapidly approaching deadline for the Low-Power Challenge to Samsung creating a fake Moon with artificial intelligence, there's plenty in the news to get this episode started. From there, the Williams plural discuss using a webcam for cheap virtual reality thrills, an impressive expansion for the Flipper Zero, and whether or not finding a bug in the Nintendo DSi browser counts as retrocomputing. Stick around to hear about the fascinating work Joshua Vasquez has been doing with DIY light guide plates, and Arya Voronova's deep-dive into PCI-Express. You want links?

Ep 209: HDMI Tempest, Norm Upscaled, Seeing Electrons, and When the Radios Go Silent
It was one of those weeks, where Elliot and Dan found a bounty of interesting hacks to choose from for the podcast, making it hard to pick. But pick we did, and we found so many deep and important questions. What good is a leaky HCMI cable? Good for falling down a TEMPEST-like rabbit hole, that's what. Why would you use a ton of clay to make a car? Because it's cool, that's why. What does an electron look like? A little like a wiggling wire, but mostly it looks like a standing wave... of waves. Is artificial intelligence going to take over all the code and start suing us for copyright violations? Maybe yes, maybe no, but we're definitely in a strange, new world. And when all our media is on demand, what is the spectrum that broadcasters currently use going to be good for? It's not all heavy questions, of course; we found a lot of fun hacks, like an extreme drill press makeover, a couple of low-power cyberdecks, the return of Norm Abram in glorious AI-generated HD, getting up close and personal with flip dot displays, and a sled that lets you go uphill as easily as going downhill. For links and more, head on over to Hackaday.

Ep 208: Hallucinating Robots, Floppy Cartridges, and a Flexure Synth French Horn
This week, Editor-in-Chief Elliot Williams and (former Assignments Editor) Kristina Panos stood around talking about the greatest hacks of the previous week. But first, we've got a contest running now through March 21st -- the Low Power Challenge! Kristina almost got What's That Sound this week, but could only describe it as some sort of underwater organ, so still no t-shirt for her. But [BalkanBoy] knew exactly what it was -- the Zadar Sea Organ in Croatia. Then it's on to the hacks, beginning with the most beautiful sea of 7-segments you'll likely ever see. We gush over a tiny PC in a floppy drive that uses custom cartridges, dish about an expressive synth that uses a flexure mechanism, and enjoy a loving ode to the vacuum fluorescent display.
