Ep 336: DIY Datasette, Egg Cracking Machine, and Screwing 3D Prints
Thunderstorms were raging across southern Germany as Elliot Williams was joined by Jenny List for this week's podcast. The deluge outside didn't stop the hacks coming though, and we've got a healthy smorgasbord for you to snack from. There's the cutest ever data cassette recorder taking a tiny Olympus dictation machine and re-engineering it with a beautiful case for the Commodore 64, a vastly overcomplex machine for perfectly cracking an egg, the best lightning talk timer Hackaday has ever seen, and a demoscene challenge that eschews a CPU. Then in Quick Hacks we've got a QWERTY slider phone, and a self-rowing canoe that comes straight out of Disney's The Sorcerer's Apprentice sequence. For a long time we've had a Field guide series covering tech in infrastructure and other public plain sight, and this week's one dealt with pivot irrigation. A new subject for Jenny who grew up on a farm in a wet country. Then both editors are for once in agreement, over using self-tapping screws to assemble 3D-printed structures. Sit back and enjoy the show!

Ep 334: Radioactive Shrimp Clocks, Funky Filaments, Owning the Hardware
In this episode of the Hackaday Podcast, editors Elliot Williams and Tom Nardi start out with a warning about potentially radioactive shrimp entering the American food supply via Walmart, and things only get weirder from there. The extra spicy shrimp discussion makes a perfect segue into an overview of a pair of atomic One Hertz Challenge entries, after which they'll go over the latest generation of 3D printer filament, using an old Android smartphone as a low-power Linux server, some tips for creating better schematics, and Lorde's specification-bending transparent CD. Finally, you'll hear about how the nature of digital ownership influences the hardware we use, and on the other side of the coin, how open source firmware like QMK lets you build input devices on your terms. , and as always, tell us what you think about this episode in the comments!

Ep 333: Nightmare Whiffletrees, 18650 Safety, and a Telephone Twofer
This week, Hackaday's Elliot Williams and Kristina Panos met up over the tubes to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous week. In Hackaday news, while they're hot! Also, ticks on, but time is running out. You have until Tuesday, August 19th to show us what you've got, so head over to Hackaday.IO and get started now. Finally, its the end of eternal September as after all these years. On What's That Sound, Kristina got sort of close, but this is neither horseshoes nor hand grenades. Can you get it? If so, you could win a limited edition Hackaday Podcast t-shirt! After that, it's on to the hacks and such, beginning with a talking robot that uses typewriter tech to move its mouth. We take a look at hacking printed circuit boards to create casing and instrument panels for a PDP-1 replica. Then we explore a fluid simulation business card, witness a caliper shootout, and marvel at one file in six formats. Finally, it's a telephone twofer as we discuss the non-hack-ability of the average smart phone, and learn about what was arguably the first podcast.

Ep 332: 5 Axes are Better than 3, Hacking Your Behavior, and the Man Who Made Models
Elliot and Dan got together this week for a review of the week's hacking literature, and there was plenty to discuss. We addressed several burning questions, such as why digital microscopes are so terrible, why computer systems seem to have so much trouble with names, and if a thermal receipt printer can cure ADHD. We looked at a really slick 5-axis printer that COVID created, a temperature-controlled fermentation setup, and a pseudo-Mellotron powered by a very odd tape recorder. We also learned little about designing 3D printed parts with tight tolerances, stepping a PC power supply up to ludicrous level, and explored a trio of unique entries for the One Hertz Challenge. And for the Can't Miss section, we looked at what happens to planes when they get hit by lightning (and how they avoid it), and say goodbye to the man who launched a lot of careers by making model kits. It was also exciting to learn that the first day of Supercon is Halloween, which means a Friday night sci-fi cosplay party. It's gonna be lit.

Ep 331: Clever Machine Tools, Storing Data in Birds, and the Ultimate Cyberdeck
Another week, another Hackaday podcast, and for this one Elliot is joined by Jenny List, fresh from the BornHack hacker camp in Denmark. There's a definite metal working flavour to this week's picks, with new and exciting CNC techniques and a selective electroplater that can transfer bitmaps to metal. But worry not, there's plenty more to tease the ear, with one of the nicest cyberdecks we've ever seen, and a bird that can store images in its song. Standout quick hacks are a synth that makes sounds from Ethernet packets, and the revelation that the original PlayStation is now old enough to need replacement motherboards. Finally we take a closer look at the huge effort that goes in to monitoring America's high voltage power infrastructure, and some concerning privacy news from the UK. Have a listen!

Ep 327: A Ploopy Knob, Rube-Goldberg Book Scanner, Hard Drives And Power Grids Oscillating Out Of Control
It's Independence Day here in the USA, but if you're not a fan of fireworks and hot dogs, Elliot and Dan's rundown of the best hacks of the week is certainly something to celebrate. Rest easy, because nothing exploded, not even the pneumatic standing desk that [Matthias] tore into, nor the electroplated 3D prints that [H3NDRIK] took a blowtorch to. We both really loved the Ploopiest knob you've ever seen, which would be even Ploopier in anodized aluminum, as well as an automatic book scanner that takes its job very seriously. We looked into the mysteries of the Smith chart, another couple of fantastic student projects out of Cornell, the pros and cons of service loops, and what happened when the lights went out in Spain last Spring. And what does Janet Jackson have against laptops anyway?

Ep 326: A DIY Pockel Cell, Funny Materials to 3D Print With, and Pwning a Nissan Leaf
Time for another European flavoured Hackaday Podcast this week, as Elliot Williams is joined by Jenny List, two writers sweltering in the humidity of a Central European summer. Both of our fans and air conditioners made enough noise to be picked up on the microphone when they were turned on, so we're suffering for your entertainment. The big Hackaday news stories of the week are twofold, firstly , and then the announcement of a fresh competition: . Get your once-a-second projects ready! This week gave us a nice pile of interesting hacks, including some next-level work growing and machining the crystal for a home-made Pockels cell light valve, an pcoming technique for glass 3D prints, and enough vulnerabilities to make any Nissan Leaf owner nervous. We note that mechanical 7-segment displays are an arena showing excellent hacks, and we're here for it. Meanwhile among the quick hacks a filament made of PLA with a PETG core caught Elliot's eye, while Jenny was impressed with a beautifully-made paper tape punch. Finally in the can't miss section, The latest in Dan Maloney's Mining and Refining series looks at drilling and blasting. Such an explosive piece should come last, but wait! There's more! Al Williams gives us a potted history of satellite phones, and explains why you don't carry an Iridium in your pocket.

Ep 325: The Laugh Track Machine, DIY USB-C Power Cables, and Plastic Punches
This week, Hackaday's Elliot Williams and Al Williams caught up after a week-long hiatus. There was a lot to talk about, including clocks, DIY USB cables, and more. In Hackaday news, <a href="https://hackaday.io/contest/202866-2025-pet-hacks-challenge">the 2025 Pet Hacks Contest</a> is a wrap. Winners will be announced soon, so stay tuned. Meanwhile, how'd you like a free ticket to attend Supercon? Well, free if you <a href="https://hackaday.com/2025/05/22/hackaday-supercon-2025-call-for-participation-we-want-you/">submit a talk</a> and get accepted. November is right around the corner, so get those talks ready. Hackaday is a big fan of the <a href="https://hackaday.com/2025/06/12/end-of-an-era-noaas-polar-sats-wind-down-operations/">NOAA Polar sats</a>, and it looks like they are on their last figurative legs. The agency has left them up for now, but won't be keeping them in shape, and if they misbehave, they may be neutralized for safety. Since Elliot was off, Al supplied the sound, and in a bout of karma, Elliot had to do the guessing this week. How'd he do? Not bad, but there's room to do better. If you do better, there could be a coveted Hackaday Podcast T-shirt in your future. Moving on the hacks, the guys were interested in magnets, clocks, cables, 3D printed machine tools, and even old moonbase proposals. For the can't miss articles, Al took the bifecta, since Elliot picked a piece on the machine that generated laugh tracks in the latter part of the 20th century and Al shamelessly picked his own article about the role of British ham radio operators during WWII. Miss anything? . As always, drop a comment and tell us what you think about the week in Hackaday.

Ep 323: Impossible CRT Surgery, Fuel Cells, Stream Gages, and a Love Letter to Microcontrollers
Our choice of hacks included a fond look at embedded systems and the classic fashion sense of Cornell's Bruce Land, risky open CRT surgery, a very strange but very cool way to make music, and the ultimate backyard astronomer's observatory. We talked about Stamp collecting for SMD prototyping, crushing aluminum with a boatload of current, a PC that heats your seat, and bringing HDMI to the Commodore 64. We also took a look at flight tracking IRL, a Flipper-based POV, the ultimate internet toaster, and printing SVGs for fun and profit.

We're back in Europe for this week's Hackaday podcast, as Elliot Williams is joined by Jenny List. In the news this week is the passing of Ed Smylie, the engineer who devised the famous improvised carbon dioxide filter that saved the Apollo 13 astronauts with duct tape. Closer to home is the announcement of the call for participation for this year's Hackaday Supercon; we know you will have some ideas and projects you'd like to share. Interesting hacks this week include a new Mac Plus motherboard and Doom (just) running on an Atari ST, while a LoRa secure messenger and an astounding open-source Ethernet switch captivated us on the hardware front. We also take a dive into the Mouse programming language, a minimalist stack-based environment from the 1970s. Among the quick hacks are a semiconductor dopant you can safely make at home, and a beautiful Mac Mini based cyberdeck. Finally, we wrap up with our colleague [Maya Posch] making the case for a graceful degradation of web standards, something which is now sadly missing from so much of the online world, and then with the discovery that ChatGPT can make a passable show of emulating a Hackaday scribe. Don't worry folks, we're still reassuringly meat-based.

It's the podcast so nice we recorded it twice! Despite some technical difficulties (note to self: press the record button significantly before recording the outro), Elliot and Dan were able to soldier through our rundown of the week's top hacks. We kicked things off with a roundup of virtual keyboards for the alternate reality crowd, which begged the question of why you'd even need such a thing. We also looked at a couple of cool demoscene-adjacent projects, such as the ultimate in oscilloscope music and a hybrid knob/jack for eurorack synth modules. We also dialed the Wayback Machine into antiquity to take a look at Clickspring's take on the origins of precision machining; spoiler alert -- you can make gas-tight concentric brass tubing using a bow-driven lathe. There's a squishy pneumatic robot gripper, an MQTT-enabled random number generator, a feline-friendly digital stethoscope, and a typewriter that'll make you Dymo label maker jealous. We'll also mourn the demise of electronics magazines and ponder how your favorite website fills that gap, and learn why it's really hard to keep open-source software lean and clean. Short answer: because it's made by people.

Ep 318: DIY Record Lathe, 360 Degree LIDAR, and 3D Printing Innovation Lives!
This week Elliot Williams was joined by fellow Europe-based Hackaday staffer Jenny List, to record the Hackaday Podcast as the dusk settled on a damp spring evening. On the agenda first was robotic sport, as a set of bipedal robots competed in a Chinese half-marathon. Our new Robot overlords may have to wait a while before they are fast enough chase us meatbags away, but it demonstrated for us how such competitions can be used to advance the state of the art. The week's stand-out hacks included work on non-planar slicing to improve strength of 3D prints. It's safe to say that the Cartesian 3D printer has matured as a device, but this work proves there's plenty more in the world of 3D printing to be developed. Then there was a beautiful record cutting lathe project, far more than a toy and capable of producing good quality stereo recordings. Meanwhile it's always good to see the price of parts come down, and this time it's the turn of LIDAR sensors. There's a Raspberry Pi project capable of astounding resolution, for a price that wouldn't have been imaginable only recently. Finally we retrned to 3D printing, with an entirely printable machine, including the motors and the hot end. It's a triumph of printed engineering, and though it's fair to say that you won't be using it to print anything for yourself, we expect some of the very clever techniques in use to feature in many other projects. The week's cant-miss articles came from Maya Posch with a reality check for lovers of physical media, and Dan Maloney with a history of x-ray detection. You'll find all the links over at Hackaday!

When Hackaday editors Elliot Williams and Al Williams need a break from writing posts, they hop on the podcast and talk about their favorite stories of the past week. Want to know what they were talking about? Listen in below and find out! In an unusual twist, a listener sent in the sound for this week's What's This Sound competition, so it turns out Elliot and Al were both stumped for a change. See if you can do better, and you might just score a Hackaday Podcast T-shirt. On the hacking front, the guys talked about what they hope to see as entries in the pet hacking contest, quantum diamonds (no kidding), spectrometers, and several science projects. There was talk of a tiny robot, a space mouse—the computer kind, not a flying rodent—and even an old-fashioned photophone that let Alexander Graham Bell use the sun like a string on a paper cup telephone. Things really heat up at the end, when there is talk about computer programming ranging from COBOL to Vibe programming. In case you've missed it, Vibe programming is basically delegating your work to the AI, but do you really want to? Maybe, if your job is to convert all that old COBOL code.

This week, Hackaday's Elliot Williams and Kristina Panos met up across the (stupid, lousy) time zones to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous week. Again, no news is good news. On What's That Sound, Kristina didn't get close at all, but at least had a guess this time. If you think you can identify the sound amid all the talking, you could win a Hackaday Podcast t-shirt! After that, it's on to the hacks and such, beginning with a Dr. Jekyll and Mr. Hyde situation when it comes to a pair of formerly-cloud music players. We take a look at a crazy keyboard hack, some even crazier conductive string, and a perfectly cromulent list of 70 DIY synths on one wild webpage. Finally, we rethink body art with LEDs, and take a look at a couple of printing techniques that are a hundred years or so apart in their invention.

Ep 314: It's Pi, but Also PCBs in Living Color and Ultrasonic Everything
It might not be Pi Day anymore, but Elliot and Dan got together for the approximately 100*Pi-th episode of the Podcast to run through the week's coolest hacks. Ultrasound seemed to be one of the themes, with a deep dive into finding bugs with sonar as well as using sound to cut the cheese -- and cakes and pies, too. The aesthetics of PCBs were much on our minds, too, from full-color graphics on demand to glow-in-the-dark silkscreens. Is automation really needed to embed fiber optics in concrete? Absolutely! How do you put plasma in a bottle? Apparently, with kombucha, Nichrome, and silicone. If you need to manage your M:TG cards, scribble on the walls, or build a mechanical chase light, we've got the details. And what exactly is a supercomputer? We can't define it, but we know one when we see it.

We're firmly in Europe this week on the Hackaday podcast, as Elliot Williams and Jenny List are freshly returned from Berlin and Hackaday Europe. A few days of mingling with the Hackaday community, going through mild panic over badges and SAOs, and enjoying the unique atmosphere of that city. After discussing the weekend's festivities we dive right into the hacks, touching on the coolest of thermal cameras, wildly inefficient but very entertaining wireless power transfer, and a restrospective on the capacitor plague from the early 2000s. Was it industrial espionage gone wrong, or something else? We also take a moment to consider spring PCB cnnectors, as used by both one of the Hackaday Europe SAOs, and a rather neat PCB resistance decade box, before looking at a tryly astounding PCB blinky that sets a new miniaturisation standard. In our quick roundup the standouts are a 1970s British kit synthesiser and an emulated 6502 system written in shell script, and in the can't-miss section we look at a new contender fro the smallest microcontroller, and the posibility that a century of waste coal ash may conceal a fortune in rare earth elements. .

Ep 312: Heart Attacks, the Speed of Light, and Self-balancing
Elliot does the podcast on the road to Supercon Europe, and Al is in the mood for math and nostalgia this week. Listen in and find out what they were reading on Hackaday this week. The guys talked about the ESP-32 non-backdoor and battery fires. Then it was on to the hacks. Self-balancing robots and satellite imaging were the appetizers, but soon they moved on to Kinect cameras in the modern day. Think you can't travel at the speed of light? Turns out that maybe you already are. Did you know there was a chatbot in 1957? Well, sort of. For the can't miss stories: watches monitor your heart and what does the number <em>e</em> really mean? if you want to follow along, and as always, tell us what you think about this episode in the comments!

Ep 311: AirTag Hack, GPS Rollover, and a Flat-Pack Toaster
This week, Elliot Williams and Tom Nardi start off the episode by announcing Arduino co-founder David Cuartielles will be taking the stage as the keynote speaker at Hackaday Europe. In his talk, we'll hear about a vision of the future where consumer electronics can be tossed in the garden and turned into compost instead of sitting in a landfill for the next 1,000 years or so. You'll also hear about a particularly clever manipulation of Apple's AirTag infrastructure, how a classic kid's toy was turned into a unique display with the help of computer vision, and the workarounds required to keep older Global Positioning System (GPS) hardware up and running. They'll also cover DIY toasters, extracting your data from a smart ring before the manufacturer can sell it, a LEGO interferometer, and a new feature added to the Bus Pirate 5's already impressive list of capabilities. Capping off the episode there's a discussion about the surprising (or depending on how you think about it, unsurprising) amount of hardware that was on display at FOSDEM this year, and the history of one of man's most infernal creations, the shopping cart wheel lock. and as always, tell us what you think about this episode in the comments!

Ep 310: Cyanotypes, Cyberdecks, and the Compass CNC
This week, Hackaday's Elliot Williams and Kristina Panos met up in a secret location with snacks to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous week. First up in the news, and there's a lot of it: we announced the Hackaday Europe 2025 workshops and a few more speakers, though the big keynote announcement is still to come. In case you missed it, KiCad 9 moved up into the pro league, and finally, we're hiring, so come join us in the dungeon. On What's That Sound, Kristina didn't get close at all, but at least had a guess this time. That's okay, though, because nobody got it right! We're still giving a t-shirt away to [AlwaysTheWrongAnswer], though, probably because Elliot has a thing for using random number generators. Then it's on to the hacks and such beginning with a beautiful handheld compass CNC and cyanotype prints made with resin printer's UV light. After that, we take a look at open-source random numbers, a 3D-printed instant camera, and a couple of really cool cyberdecks. Finally, we discuss whether DOOM is doomed as the port of choice in this day and age, and kvetch about keyboards.
