Ep 320: A Lot of Cool 3D Printing, DIY Penicillin, and an Optical Twofer 42:39

۲ روز پیش42:39

42:39

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.'.

Ep 319: Experimental Archaeology, Demoscene Oscilloscope Music, and Electronic Memories 56:57

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! 1:02:00

16 روز پیش1:02:00

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.

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'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.

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?

1:04:39

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.

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!…

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).…
