Hackaday Podcast

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. Finally, we wrapped things up with a look at the tech behind real-time river flow tracking and a peek inside the surprisingly energetic world of fuel cells. Check out all the links over at Hackaday!

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.

Join Hackaday Editors Elliot Williams and Tom Nardi as they take a whirlwind tour of the best and brightest hacks of the last week. This episode starts off with an update about that Soviet Venus lander that's been buzzing the planet, then moves on to best practices for designing 3D printed parts, giving Chrome OS devices a new lease on life, and a unique display technology that brings a Star Wars prop to life. You'll also hear about designing new motherboards for beloved old computers, why you might want to put your calipers on a flatbed scanner, and a NASA science satellite that's putting in double duty as a wartime reporter. Finally, they'll cover the interesting physics of meteor burst communications, and the latest developments in the ongoing libogc license carfuffle. Check out the links if you want to follow along, and as always, tell us what you think about this episode in the comments!

This week, Hackaday's Elliot Williams and Kristina Panos met up across the universe to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous week. In Hackaday news, the 2025 Pet Hacks Contest rolls on. You have until June 10th to show us what you've got, so head over to Hackaday.IO and get started today! On What's That Sound, Kristina actually got it this time, although she couldn't quite muster the correct name for it, however at Hackaday we'll be calling it the "glassophone" from now on. Congratulations to [disaster_recovered] who fared better and wins a limited edition Hackaday Podcast t-shirt! After that, it's on to the hacks and such, beginning with a complete and completely-documented wireless USB autopsy. We take a look at a lovely 3D-printed downspout, some DIY penicillin, and a jellybean iMac that's hiding a modern PC. Finally, we explore a really cool 3D printing technology, and ask what happened to typing 'www.'.

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.

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.

Join Hackaday Editors Elliot Williams and Tom Nardi as they talk about the best stories and hacks of the week. This episode starts off with a discussion of the Vintage Computer Festival East and Philadelphia Maker Faire -- two incredible events that just so happened to be scheduled for the same weekend. From there the discussion moves on to the latest developments in DIY soft robotics, the challenge of running Linux on 8-pin ICs, hardware mods to improve WiFi reception on cheap ESP32 development boards, and what's keeping old smartphones from being reused as general purpose computers. You'll also hear about Command and Conquer: Red Alert running on the Pi Pico 2, highly suspect USB-C splitters, and producing professional looking PCBs at home with a fiber laser. Stick around to the end to hear about the current state of non-Google web browsers, and a unique new machine that can engrave circuit boards with remarkable accuracy.

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. Check out the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!  

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. Check out all the links over at Hackday!

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. Follow the links over at Hackaday.

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 e really mean? Check out the links on Hackaday if you want to follow along, and as always, tell us what you think about this episode in the comments!

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. Check out the links over at Hackaday, and as always, tell us what you think about this episode in the comments!

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.  

This week Hackaday Editors Elliot Williams and Tom Nardi start things off with updates on the rapidly approaching Hackaday Europe and the saga of everyone's favorite 3D printed boat. From there they'll cover an impressive method of seeing the world via WiFi, Amazon's latest changes to the Kindle ecosystem, and an alternate reality in which USB didn't take over the peripheral world. You'll also hear about a multi-level hack that brings the joys of Linux into the world of Animal Crossing, 3D printed circuit components, and the imminent release of KiCAD 9. Stick around until the end to learn about a unique hardened glass from East Germany and the disappointing reality of modern voice control systems.

It's Valentine's Day today, and what better way to capture your beloved's heart than by settling down together and listening to the Hackaday Podcast! Elliot Williams is joined by Jenny List for this week's roundup of what's cool in the world of hardware. We start by reminding listeners that Hackaday Europe is but a month away, and that a weekend immersed in both hardware hacking and the unique culture offered by the city of Berlin can be yours. The stand-out hack of the week is introduced by Elliot, Henrik Forstén's synthetic aperture radar system mounted on a cheap quadcopter, pushing the limits of construction, design, and computation to create landscape imagery of astounding detail. Most of us will never create our own SAR system, but we can all learn a lot about this field from his work. Meanwhile Jenny brings us Sylvain Munaut's software defined radio made using different projects that are part of Tiny Tapeout ASICs. The SDR isn't the best one ever, but for us it represents a major milestone in which Tiny Tapeout makes the jump from proof of concept to component. We look forward to more of this at more reasonable prices in the future. Beyond that we looked at the porting of Google Find My to the ESP32, how to repair broken zippers, and tuning in to ultrasonic sounds. Have fun listening, and come back next week for episode 309!  

The answer is: Elliot Williams, Al Williams, and a dozen or so great hacks. The question?  What do you get this week on the Hackaday podcast? This week's hacks ran from smart ring hacking, to computerized tattoos. Keyboards, PCBs, and bicycles all make appearances, too. Be sure to try to guess the "What's that sound?" You could score a cool Hackaday Podcast T. For the can't miss this week, Hackaday talks about how to dispose of the body in outer space and when setting your ship's clock involved watching a ball drop.  

It was Dan and Elliot behind the microphones today for a transatlantic look at the week in hacks. There was a bucket of news about AI, kicked off by Deepseek suddenly coming into the zeitgeist and scaring the pants off investors for... reasons? No matter, we're more interested in the tech anyway, such as a deep dive into deep space communications from a backyard antenna farm that's carefully calibrated to give the HOA fits. We got down and dirty with capacitors, twice even, and looked at a clever way to stuff two websites into one QR code. It's all Taylor, all the time on every channel of the FM band, which we don't recommend you do (for multiple reasons) but it's nice to know you can. Plus, great kinetic art project, but that tooling deserves a chef's kiss. Finally, we wrap up with our Can't Miss articles where Jenny roots for the right to repair, and Al gives us the finger(1).  

This week, Hackaday's Elliot Williams and Kristina Panos joined forces and Wonder-Twin rings 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: Big boo to Bambu Labs, who have tried to clarify their new authentication scheme and probably only dug themselves in deeper with their customers. On What's That Sound, Kristina didn't get close at all, but at least had a guess this time. Do know what it is? Let us know, and if you're right and your number comes up, you can keep warm in a limited edition Hackaday Podcast t-shirt. Then it's on to the hacks and such beginning with a rather nice reverse-engineering of the Yamaha PRS-E433 keyboard, which led to a slice of Bad Apple playing on the tiny screen. After that, we take a look at an NES musical instrument, how to make wires explode with energy, and a really cool space mouse that uses flexures. Finally, we talk about a piece of forgotten Internet history, and a whole bunch of keyboards. Check out the links over at Hackaday if you want to follow along, and as always, tell us what you think about this episode in the comments!

It's podcast time again, and this week Dan sat down with Elliot for a look back at all the cool hacks we've written about. We started off talking about Hackaday Europe, which is coming up in March -- seems unlikely that it's just around the corner, but there it is. There's also good news: the Hack Chat is back, and we started things off with a bang as Eben Upton stopped by to talk all things Pi. Separately, we talked about fault injection attacks, including how to find the hidden cup of  0xC0FFEE in an RP2350. We saw a very cool piece of LED jewelry that does a fluid simulation, a direct conversion radio that's all laid out in front of you, and the scrunchiest mechanical digital clock you'll ever see. We saw blinkenlights for blinkenlights' sake, all the ways to put threads in your prints, and how to ditch to coax and wire up your antennas with Cat 6 cable. Plus, it's an Al Williams twofer in the Can't-Miss Articles, with a look back at life before GPS and how you can tune into digital ham radio, no radio required.

As the holiday party season fades away into memory and we get into the swing of the new year, Elliot Williams is joined on the Hackaday Podcast by Jenny List for a roundup of what's cool in the world of Hackaday. In the news this week, who read the small print and noticed that Benchy has a non-commercial licence? As the takedown notices for Benchy derivatives fly around, we muse about the different interpretations of open source, and remind listeners to pay attention when they choose how to release their work. The week gave us enough hacks to get our teeth into, with Elliot descending into the rabbit hole of switch debouncing, and Jenny waxing lyrical over a crystal oscillator. Adding self-driving capability to a 30-year-old Volvo caught our attention too, as did the intriguing Cheap Yellow Display, an ESP32 module that has (almost) everything. Meanwhile in the quick hacks, a chess engine written for a processor architecture implemented entirely in regular expressions impressed us a lot, as did the feat of sending TOSLINK across London over commercial fibre networks. Enjoy the episode, and see you again next week! And check out the links over at Hackaday.

After a bit too much eggnog, Elliot Williams and Al Williams got together to see what Hackaday had been up to over the holiday. Turns out, quite a bit. There was a lot to cover, but the big surprise was the "What's that Sound" competition. Do you know who had the correct answer from the last show? No one! So they guys did the right thing and drew from all the entrants for a coveted Hackaday Podcast T-shirt. Back to the hacks, you'll hear about USB-C and the EU, what to do when the Kickstarter product you had your heart set on doesn't deliver, and a very strange way to hack some power grids wirelessly. If you are interested in physics cameras, modifying off-the-shelf gear, or a fresh approach to color 3D printing, they'll talk about that, too. Finally,  you can find out what Tom Nardi thought of Hackaday in the year past, and if your next ocean voyage will have to stop for a charge.  

Hackaday is having a happy holiday, and we hope you are too!  We'll be back next Friday, so stay tuned.

Twas the week before Christmas when Elliot and Dan sat down to unwrap a pre-holiday bundle of hacks. We kicked things off in a seasonally appropriate way with a PCB Christmas card that harvests power from your microwave or WiFi router, plus has the potential to be a spy tool. We learned how to grow big, beautiful crystals quickly, just in case you need some baubles for the tree or a nice pair of earrings. Speaking of last-minute gifts, perhaps you could build a packable dipole antenna, a very durable PCB motor, or a ridiculously bright Fibonacci simple add-on for your latest conference badge. We also looked into taking a shortcut to homebrew semiconductors via scanning electron microscopes, solved the mystery of early CD caddies, and discussed the sad state of table saw safety and the lamentable loss of fingers, or fractions thereof.

This week on the big 300th episode, Hackaday's Elliot Williams and Kristina Panos teamed up to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous week. So basically, business as usual. First up in the news: it's time for the Hackaday Europe 2025 call for proposals! Do you have a tale of hardware, firmware, or software that must be shared with the Hackaday crowd? Then this is your chance to regale us with a 20- or 40-minute talk. You know we love to hear new voices, so be sure to consider proposing a talk. On What's That Sound, it's a results show week. Congratulations to [Kelvin] who was one of many that correctly identified it as the Wii startup sound. Kristina will just be over here with her Pikachu64 with the light-up cheeks. Then it's on to the hacks and such beginning with a rather nice reverse-engineering of the PS1, which surprisingly did it with a two-sided board. Then it's on to a smartphone home server, magic eye images in a spreadsheet, and the math behind the music of 80s. Finally, we talk about disc cameras, the hovercraft revolution, and a whole mess of keyboards. Check out the links if you want to follow along, and as always, tell us what you think about this episode in the comments!

On this episode of the Hackaday Podcast, Editors Elliot Williams and Tom Nardi talk about the optical witchcraft behind holograms, the finer points of designing 3D printable threads, and the challenges of switching your local network over to IPv6. They'll also cover how a clever software patch improves the graphics in a flight simulator from the 1990s, and why spacecraft flying into orbit powered by the SABRE engine is going to remain a dream for now. From there you'll hear about a reproduction VW gas gauge that works better than the real thing, custom ball screws, and the latest and greatest in homebrew battery charging. Finally, they'll cap the episode off by exploring the conundrum that's heating up London's Underground, and diving into the (mostly) fictional history of teleportation.

This week's Hackaday podcast has a European feel, as Elliot Williams is joined by Jenny List for a look at the week's happenings in the world of cool hardware hacks. Starting with the week's news, those Redbox vending machines continue to capture the attention of hackers everywhere, and in the race to snag one before they're carted off for recycling someone has provided the missing hardware manual in the form of a wiki. Europeans can only look on wistfully. Then there's the curious case of life on the asteroid sample, despite the best efforts of modern science those pesky earth bacteria managed to breach all their anti-contamination measures. Anyone who's had a batch of homebrew go bad feels their pain. The week provided plenty of hacks, with the team being wowed by [Bitluni]'s CRT-like laser projector, then the many ingenious ways to 3D-print a hinge, and perhaps one of the most unforgiving environments in the home for a piece of robotics. Meanwhile our appetite for cool stuff was sated by an entire family of Japanese games consoles we'd never heard of, and the little voltage reference whose data sheet also had an audio amplifier circuit. Finishing up, our colleague Arya has many unorthodox uses for a USB-C cable, and we have a frank exchange of views about Linux audio. Check out all the links, and by all means, give us a roasting in the comments!

This week on the Podcast, Hackaday's Elliot Williams and Kristina Panos joined forces 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: Elliot was at Electronica and spotted a wild Raspberry Pi Compute Module 5. And just as excitingly, FreeCAD has finally reached version 1.0, which means it's stable and ready for real work. Kristina is getting tired of losing at What's That Sound, so she'll have to come up with some to stump you all. Can you get this week's sound? If you can, and your number comes up, you get a special Hackaday Podcast t-shirt. Then it's on to the hacks and such, but first, there's even more news and opinion to be had in Tom's review of Prusa's new printer, which happens to be closed-source. Then we'll discuss another printer that prints upside-down, an elegant cyberdeck, and a cyberpunk pocket watch. Finally, we talk about the Great Redbox Cleanup, and take a look at man-made stalactites.

In this episode you'll get to hear not one, not two, but three Hackaday Editors! Now that the dust has mostly settled from the 2024 Hackaday Supercon, Al Williams joins Elliot and Tom to compare notes and pick out a few highlights from the event. But before that, the week's discussion will cover the questionable patents holding back a promising feature for desktop 3D printers, a new digital book from NODE, and the surprisingly limited history of welding in space. You'll also hear about the challenge of commercializing free and open source software, the finicky optics of the James Web Space Telescope, and the once exciting prospect of distributing software via pages of printed barcodes.

With Superconference 2024 in the books, Dan joined Elliot, fresh off his flight back from Pasadena, to look through the week (or two) in hacks. It was a pretty good crop, too, despite all the distractions and diversions. We checked out the cutest little quadruped, a wireless antenna for wireless communications, a price-tag stand-in for paper calendars, and a neat way to test hardware and software together. We take the closest look yet at why Arecibo collapsed, talk about Voyager's recent channel-switching glitch, and find out how to put old Android phones back in action. There's smear-free solder paste application, a Mims-worthy lap counter, and a PCB engraver that you've just got to see. We wrap things up with a look at Gentoo and pay homage to the TV tubes of years gone by -- the ones in the camera, for the TV sets.

With the 2024 Hackaday Supercon looming large on the horizon, Editors Elliot Williams and Tom Nardi start this episode off by talking about this year's badge and its focus on modular add-ons. From there they'll go over the results of a particularly challenging installment of What's that Sound?, discuss a promising DIY lathe that utilizes 3D printed parts filled with concrete, and ponder what the implosion of Redbox means for all of their disc-dispensing machines that are still out in the wild. You'll also hear about custom macropads, lifting SMD pins, and how one hacker is making music with vintage electronics  learning kits. Finally, they'll reassure listeners that the shifting geopolitical landscape probably won't mean the end of Hackaday.io anytime soon, and how some strategically placed pin headers can completely change how you approach designing your own PCBs. Check out the links over at Hackaday, and tell us what you think about this episode in the comments!

This week on the Podcast, Hackaday's Elliot Williams and Kristina Panos joined forces 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: we've extended the 2024 Supercon Add-On contest by a week! That's right, whether you were held up by Chinese fall holidays or not, here's your chance to get in on this action. We love to see the add-ons people make for the badge every year, so this time around we're really embracing the standard. The best SAOs will get a production run and they'll be in the swag bag at Hackaday Europe 2025. What's That Sound pretty much totally stumped Kristina once again, although she kind of earned a half shirt. Can you get it? Can you figure it out? Can you guess what's making that sound? If you can, and your number comes up, you get a special Hackaday Podcast t-shirt. Then it's on to the hacks, beginning with what actually causes warping in 3D prints, and a really cool display we'd never heard of. Then we'll discuss the power of POKE when it comes to live coding music on the Commodore64, and the allure of CRTs when it comes to vintage gaming. Finally, we talk Hackaday comments and take a look at a couple of keyboards. Check out the links if you want to follow along, and as always, tell us what you think about this episode in the comments!

Here we are in October, improbably enough, and while the leaves start to fall as the goblins begin to gather, Elliot and Dan took a break from the madness to talk about all the wonderful hacks that graced our pages this week. If there was a theme this week, it was long-term projects, like the multiple years one hacker spent going down dead ends in the quest for DIY metal 3D printing. Not to be outdone, another hacker spent seven years building a mirrorless digital camera that looks like a commercial product. And getting a solderless PCB to do the blinkenlight thing took a long time too. Looking to eliminate stringing in your 3D prints? Then you'll want to avoid the "pause and attach" approach, which intentionally creates strings in your prints. Wondering if you can 3D print bearings? You can, but you probably shouldn't unless you have a particular use in mind. And what happens when you have an infinitely large supply of Lego? Why, you build a Turing machine on steroids, of course. Finally, we take a look at this week's "Can't-Miss" articles with a look into plastic recycling and why we can't have nice things yet, and we take a trip out into orbit and examine the ins and outs of Lagrange points. And a little mea culpa from the editing desk: Sorry the podcast is coming out late this week. Audacity ate my files. If you're ever in a similar circumstance, you can probably halfway save your bacon with audacity-project-tools. Ask me how I know. Check out the links over at Hackaday.

What have you missed on Hackaday this week? Elliot Williams and Al Williams compare notes on their favorites from the week, and you are invited. The guys may have said too much about the Supercon badge this year -- listen in for a few hints about what it will be about. For hacks, you'll hear about scanning tunneling microscopes, power management for small Linux systems, and lots of inertial measurement units. The guys talked about a few impossible hacks for consumer electronics, from hacking a laptop, to custom cell phones. Of course, there are plenty more long-form articles of the week, including a brief history of what can go wrong on a spacewalk and how to get the lead out (of the ground). Don't forget to take a stab at the What's That Sound competition and maybe score a sweet Hackaday Podcast T-shirt.

This week, Hackaday Editors Elliot Williams and Tom Nardi start things off by acknowledging an incredible milestone: 20 years of Hackaday! Well, probably. When a website gets to be this old, it's a little hard to nail down when exactly things kicked off, but it seems like September of 2004 is about right. They'll also go over the latest updates for the fast-approaching Hackaday Supercon, and announce the winner of another tough What's That Sound challenge. From there, the conversation makes its way from the fascinating electrically-activated adhesive holding the latest iPhone together to pulsed-power lasers and a high flying autonomous glider designed and built by a teenager. You'll also hear about 3D printing on acrylic, home biohacking, and the Tiny Tool Kit Manifesto. Stick around to the end to hear the duo discuss the fine art of good documentation, and an incredible bodge job from Arya Voronova.

This week on the Podcast, Hackaday's Elliot Williams and Kristina Panos joined forces 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: we've announced the 2024 Tiny Games Contest winners! We asked you to show us your best tiny game, whether that means tiny hardware, tiny code, or a tiny BOM, and you did so in spades. Congratulations to all the winners and Honorable Mentions, and thanks to DigiKey, Supplyframe, and all who entered! We also announced the first round of Supercon speakers, so if you haven't gotten your ticket yet, now's the second best time. But wait, there's more! We're already a few weeks into the next contest, where we want you to show us your best Simple Supercon Add-On. We love to see the add-ons people make for the badge every year, so this time around we're really embracing the standard. The best SAOs will get a production run and they'll be in the swag bag at Hackaday Europe 2025. Then it's on to What's That Sound, which completely stumped Kristina once again. Can you get it? Can you figure it out? Can you guess what's making that sound? If you can, and your number comes up, you get a special Hackaday Podcast t-shirt. Now it's on to the hacks, beginning with non-planar ironing for smooth prints, and a really neat business card that also plays tiny games. Then we'll discuss USB modems, cool casts for broken wrists, and archiving data on paper. Finally, we ask two big questions -- where do you connect the shield, and what's the Next Big Thing gonna be? Inquiring minds want to know. Check out the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!

It's Friday the 13th, and despite having to dodge black cats and poorly located ladders, Elliot and Dan were able to get together and run down the best hacks of the first week of September. Our luck was pretty good, too, seeing how we stumbled upon a coffee table that walks your drink over to you on Strandbeest legs, a potato that takes passable photographs, and a cool LED display three times better than a boring old seven-segment. If you've never heard of the Voynich manuscript, you're in luck too, because we got a chance to look inside this medieval comic book literally, with multispectral analysis. Is your cruise ship too short? No worries, just lop it in two and add a section. Speaking of cutting things up, that's what you need to do to see how your plus-size DIY rocket engine performed after test firing. And finally, it was a sweep for Jenny this week with our "Can't Miss" articles, where she both pines for a simpler, smaller web experience and wonders what the future holds for biomass fuels.

Elliot Williams is back from vacation, and he and Al Williams got together to talk about the best Hackaday posts from the last week. Of course, the Raspberry Pi RP2350 problem generated a bit of discussion. On a lighter note, they saw laser lawn care, rooting WiFi devices, and some very black material made from wood. Need more current-sinking capability from a 555? They talked about that, too, along with a keyboard you use with your feet. The guys had a lot to say about Klipper, why you might want to move your 3D printer to it, and the FCC's stance on ham radio antennas in restricted neighborhoods. Oh, and don't forget to play "What's that Sound?"  

Even when the boss is away, the show must go on, so Dan slid back behind the guest mic and teamed up with Tom to hunt down the freshest of this week's hacks. It was a bit of a chore, with a couple of computer crashes and some side-quests down a few weird rabbit holes, but we managed to get things together in the end. Tune in and you'll hear us bemoan HOAs and celebrate one ham's endless battle to outwit them, no matter what the golf cart people say about his antennas. Are you ready to say goodbye to the magnetic stripe on your credit card? We sure are, but we're not holding our breath yet. Would you 3D print a 55-gallon drum? Probably not, but you almost can with a unique Cartesian-polar hybrid printer. And, if you think running MS-DOS on a modern laptop is hard, guess again -- or, maybe you just have to get really lucky. We also took a look at a digital watch with a beautiful display, a hacked multimeter, modern wardriving tools, switchable magnets, and debate the eternal question of v-slot wheels versus linear bearings. And finally, you won't want to miss our look at what's new with 3D scanning, and the first installment of Kristina's new "Boss Byproducts" series, which delves into the beauty of Fordite.

This week on the Podcast, we have something a little different for you. Elliot is on vacation, so Tom was in charge of running the show and he had Kristina in the hot seat. First up in the news: the 2024 Tiny Games Challenge is still underway and has drawn an impressive 44 entries as of this writing. You have until 9AM PDT on September 10th to show us your best tiny game, whether that means tiny hardware, tiny code, or a tiny BOM. Then it's on to What's That Sound, which Tom and Kristina came up with together, so there will be no pageantry about guessing. But can you get it? Can you figure it out? Can you guess what's making that sound? If you can, and your number comes up, you get a special Hackaday Podcast t-shirt. Now it's on to the hacks, beginning with an open-source liquid-fueled rocket and a really cool retro trackball laptop. Then we'll discuss screwdriver mange, the Wow! signal, and whether you're using you're calipers incorrectly. Finally, we look at a laptop that that isn't really a laptop, and one simple trick to keep things aligned on your laser engraver.

The summer doldrums are here, but that doesn't mean that Elliot and Dan couldn't sift through the week's hack and find the real gems. It was an audio-rich week, with a nifty microsynth, music bounced off the moon, and everything you always wanted to know about Raspberry Pi audio but were afraid to ask. We looked into the mysteries of waveguides and found a math-free way to understand how they work, and looked at the way Mecanum wheels work in the most soothing way possible. We also each locked in on more classic hacks, Elliot with a look at a buffer overflow in Tony Hawks Pro Skater and Dan with fault injection user a low-(ish) cost laser setup. From Proxxon upgrades to an RC submarine to Arya's portable router build, we've got plenty of material for your late summer listening pleasure.

Hackaday Editors Elliot Williams and Al Williams reflect on the fact that, as humans, we have--at most--two eyes and no warp drives. While hacking might not be the world's most dangerous hobby, you do get to work with dangerous voltages, temperatures, and frickin' lasers. Light features prominently, as the guys talk about LED data interfaces, and detecting faster-than-light travel. There's also a USB sniffer, abusing hot glue, and some nostalgia topics ranging from CRT graphics to Apollo workstations (which have nothing directly to do with NASA). The can't miss articles this week cover hacking you and how you make the red phone ring in the middle of a nuclear war.

In this episode, the CrowdStrike fiasco has Hackaday Editors Elliot Williams and Tom Nardi pondering the fragility of our modern infrastructure. From there the discussion moves on to robotic sailboats, the evolving state of bespoke computers, and the unique capabilities of the Super Nintendo cartridge. You'll also hear about cleaning paintings with lasers, the advantages of electronic word processors, stacking 3D printed parts, and the joys of a nice data visualization. They'll wrap the episode up by marveling at the techniques required to repair undersea fiber optic cables, and the possibilities (and frustrations) of PCB panelization using multiple designs.

This week on the Podcast, it's Kristina's turn to bloviate alongside Editor-in-Chief Elliot Williams. First up in the news: our fresh new contest has drawn three entries already! That's right, the 2024 Tiny Games Challenge is underway. You have until September 10th to show us your best tiny game, whether that means tiny hardware, tiny code, or a tiny BOM. Then it's on to What's That Sound, which sounded familiar to Kristina, but she couldn't place it. Can you get it? Can you figure it out? Can you guess what's making that sound? If you can, and your number comes up, you get a special Hackaday Podcast t-shirt. Then it's on to the hacks, beginning with a hack to print metal and a way to weld wood, along with a photo-resistor-based, single-pixel camera. We'll talk desiccants carbon fiber, and Baron Harkonnen. Finally, we discuss the troubles of keeping hygroscopic materials from degrading, and have a klatch about Keebin' with Kristina.

Despite the summer doldrums, it was another big week in the hacking world, and Elliot sat down with Dan for a rundown. Come along for the ride as Dan betrays his total ignorance of soccer/football, much to Elliot's amusement. But it's all about keeping the human factor in sports, so we suppose it was worth it. Less controversially, we ogled over a display of PCB repair heroics, analyzed a reverse engineering effort that got really lucky, and took a look at an adorable one-transistor ham transceiver. We also talked about ants doing surgery, picking locks with nitric acid, a damn cute dam, and how to build one of the world's largest machines from scratch in under a century. Plus, we answered the burning question: can a CRT be used as an audio amplifier? Yes, kind of, but please don't let the audiophiles know or we'll never hear the end of it.  

Get your weekly fix of great hacks with your guides, Elliot Williams and Al Williams. This week, the guys talk about hacking airline WiFi, vanishing cloud services, and hobbies adjacent to hacking, such as general aviation. Things go into the weird and wonderful when the topic turns to cavity filters, driving LEDs with a candle, and thermite. Quick hacks? Everything from vintage automated telescopes to home fusion reactors and ham radio mobile from a bicycle. Then there's the can't miss articles about the Solar Dynamics Observatory and an explainer about flash memory technology. Check out the links over on Hackaday and leave your favorite hack of the week in the comments!

In this episode, Hackaday Editors Elliot Williams and Tom Nardi kick things off with a reminder about the impending deadline for Supercon talk and workshop proposals. From there discussion moves on to the absolutely incredible tale of two brothers who solved a pair of missing person cases with their homebrew underwater vehicle, false data sneaking into OctoPrint's usage statics, and an organic input device that could give the classic mouse a run for its money. You'll also hear about cheap radar modules, open source Xbox mod chips, and lawnmowers from the grocery store. The episode wraps up with a look at the enduring mystique of perpetual motion devices, and the story of a legendary ship that might soon end up being turned into paper clips.

This week on the Podcast, it's Kristina's turn to ramble on alongside Editor-in-Chief Elliot Williams. First up in the news: Paul Allen's Living Computers Museum + Labs is being liquidated at auction after just 12 years of being open to the public. In Hackaday news, the 2024 Business Card Challenge ends next Tuesday, July 2nd, so this is your weekend to shine! Also, you've got about two weeks to get your talk proposals in for this year's Supercon. (Can you believe it's only four months away?) Then it's on to What's That Sound, at which Kristina made a couple of close-but-no-cigar guesses. Can you get it? Can you figure it out? Can you guess what's making that sound? If you can, and your number comes up, you get a special Hackaday Podcast t-shirt. Then it's on to the hacks, beginning with a $3 smartwatch that can run Python, and a completely DIY analog tape recording solution. We'll talk about making your wireless keyboard truly low power, all the steps you can take to produce perfect PCBs at home, and AI in a font. Finally, we talk about the dangers of a curious childhood, and talk about a dotcom hardware solution that could have gone far, given the right business model. Check out the links and as always, tell us what you think about this episode in the comments!

The week gone by was rich with fun hacks, and Elliot and Dan teamed up this time around to run them down for everyone. The focus this week seemed to trend to old hardware, from the recently revived Voyager 1 to a 1940s car radio, a homebrew instrument from 1979, a paper tape reader, and a 128k Mac emulator built from an RP2040. Newer hacks include a 3D-printed bottle labeler, a very hackable smart ring, and lessons learned about programming robots. We also took a look at turning old cell phones into Linux machines, making sure climbing ropes don't let you down, and snooping on orbital junk with a cool new satellite. We wrapped things up with a discussion of just how weird our solar system is, and Dan getting really jealous about Tom Nardi's recent trip to see the battleship New Jersey from an up close and personal perspective. Head on over to Hackaday to check out the links and leave your thoughts!

Join Hackaday Editors Elliot Williams and Tom Nardi for a review of the best stories to grace the front page of Hackaday this week. Things kick off with the news about Raspberry Pi going public, and what that might mean for everyone's favorite single-board computer. From there they'll cover the technology behind communicating through mud, DIY pressure vessels, pushing the 1983 TRS-80 Model 100 to its limits, and the reality of 3D printing how that the hype has subsided. You'll also hear about modifying Nissan's electric vehicles, bringing new life to one of the GameCube's oddest peripherals, and an unusually intelligent kayak. The episode wraps up with some interesting (or depressing) numbers that put into perspective just how much copper is hiding in our increasingly unused telephone network, and a look at how hardware hackers can bend the display technology that's used in almost all modern consumer electronics to our advantage.
