Hackaday Podcast

This week, Hackaday's Elliot Williams and Kristina Panos met up over assorted beverages to bring you the latest news, mystery sound results show, and of course, a big bunch of hacks from the previous seven days or so. In the news, we've launched a brand-new contest! Yes, the Green-Powered Challenge is underway, and we need your entry to truly make it a contest. You have until April 24th to enter, so show us what you can do with power you scrounge up from the environment around you! On What's That Sound, Kristina was leaning toward some kind of distant typing sounds, but [Conrad] knew it was our own Tom Nardi's steam heat radiator pinging away. After that, it's on to the hacks and such, beginning with an exploration of all the gross security vulnerabilities in a cheap WiFi extender, and we take a look inside a little black and white pay television like you'd find in a Greyhound station in the 80s and 90s. We also discuss the idea of mixing custom spray paint colors on the fly, a pen clip that never bends out of shape, and running video through a guitar effects pedal. Finally, we discuss climate engineering with disintegrating satellites, and the curse of everything device.

Hackaday editors Elliot Williams and Al Williams met up to trade their favorite posts of the week. Tune in and see if your favorites made the list. From crazy intricate automata to surprising problems in Peltier cooler designs, there's a little bit of everything. Should bikes have chains? What's the hardest thing about Star Trek computers to duplicate? Can you make a TV station from a single microcontroller? The podcast this week answers these questions and more. Plus, weigh in on the What's That Sound contest and you might just score a Hackaday Podcast T-shirt. For the Can't Miss segment, Elliot had airships on his mind, while Al's sick of passwords. But is he sick enough to take electronic pills that transmit his password?

For today's podcast Elliot Williams is joined by Jenny List, and we're pushing the limits of mobile connectivity as Jenny's coming to us from a North Sea ferry. We start by looking forward to the upcoming Hackaday Europe, with a new location in Lecco, Italy. We hope you can join us there! There's a bumper collection of hacks to talk about, with a novel soft pneumatic display, a CRT-based VR headset, an LCD photographic aperture, and a novel time-of-flight sensor array in the line-up.Then there are 3D printed PCBs, Scotch tape for a lens, and a project to map farts. We kid you not. Finally we wrap up with mind controlled toys, and a a treatise on requirements and specifications in an age of AI. Check out all the links over on Hackaday!

In the latest episode of the Hackaday Podcast, editors Elliot Williams and Tom Nardi start things off by discussing the game of lunar hide-and-seek that has researchers searching for the lost Luna 9 probe, and drop a few hints about the upcoming Hackaday Europe conference. From there they'll marvel over a miniature operating system for the ESP32, examine the re-use of iPad displays, and find out about homebrew software development for an obscure Nintendo handheld. You'll also hear about a gorgeous RGB 14-segment display, a robot that plays chess, and a custom 3D printed turntable for all your rotational needs. The episode wraps up with a sobering look at the dangers of industrial robotics, and some fascinating experiments to determine if a decade-old roll of PLA filament is worth keeping or not.

This week, Hackaday's Elliot Williams and Kristina Panos met up over coffee to bring you the latest news, mystery sound results show, and of course, a big bunch of hacks from the previous seven days or so. We found no news to speak of, except that Kristina has ditched Windows after roughly 38 years. What is she running now? What does she miss about Windows? Tune in to find out. On What's That Sound, Kristina thought it was a jackhammer, but [Statistically Unlikely] knew it was ground-tamper thingy, and won a Hackaday Podcast t-shirt! Congratulations! After that, it's on to the hacks and such, beginning with 3D printing on the nano scale, and a couple of typewriter-based hacks. Then we take a look at the beauty of the math behind graph theory, especially when it comes to circuit sculptures and neckties. We also talk display hacking, macro pads with haptic feedback knobs, and writing code in Welsh. Finally, we discuss the Virtual Boy, and ponder whether vibe coding is killing open source.

Another chilly evening in Western Europe, as Elliot Williams is joined this week by Jenny List to chew the fat over the week's hacks. It's been an auspicious week for anniversaries, with the hundredth since the first demonstration of a working television system in a room above a London coffee shop. John Logie Baird's mechanically-scanned TV may have ultimately been a dead-end superseded by the all-electronic systems we all know, but the importance of television for the later half of the 20th century and further is beyond question. The standout hacks of the week include a very clever use of the ESP32's WiFi API to detect people moving through a WiFi field, a promising open-source smartphone, another ESP32 project in a comms system for cyclists, more cycling on tensegrity spokes, a clever way to smooth plaster casts, and a light sculpture reflecting Wi-Fi traffic. Then there are a slew of hacks including 3D printed PCBs and gem-cut dichroic prisms, before we move to the can't-miss articles. There we're looking at document preservation, and a wallow in internet history with a look at the Netscape brand. As usual all the links you need can be found over on Hackaday, so listen, and enjoy!

Hackaday Editors Elliot Williams and Al Williams took a break to talk about their favorite hacks last week. You can drop in to hear about articulated mirrors, triacs, and even continuous 3D-printing modifications. Flying on an airplane this weekend? Maybe wait until you get back to read about how the air traffic control works. Back home, you can order a pizza on a Wii or run classic Basic games on a calculator. For the can't miss articles, the guys talked about very low Earth orbit satellites and talked about readers who dumpster dive.

Join Hackaday Editors Elliot Williams and Tom Nardi as they swap their favorite hacks and stories from the week. In this episode, they'll start off by marveling over the evolution of the "smart knob" and other open hardware input devices, then discuss a futuristic propulsion technology you can demo in your own kitchen sink, and a cheap handheld game system that get's a new lease on life thanks to the latest version of the ESP32 microcontroller. From there they'll cover spinning CRTs, creating custom GUIs on Android, and yet another thing you can build of out that old Ender 3 collecting dust in the basement. The episode wraps up with a discussion about putting Valve's Steam Deck to work and a look at the history-making medical evacuation of the International Space Station.

This week, Hackaday's Elliot Williams and Kristina Panos met up over coffee to bring you the latest news, mystery sound results show, and of course, a big bunch of hacks from the previous seven days or so. On What's That Sound, Kristina had no idea what was going on, but [Flippin' Heck] knew it was a flip dot display, and won a Hackaday Podcast t-shirt! Congratulations! After that, it's on to the hacks and such, with not one but two ways of seeing sound. We also take a look at benchmarking various Windows releases against each other on 12-year-old hardware. We also talk about painting on floppies and glitching out jpegs in a binary text editor. Finally, we discuss the history and safety of autopilot, and take a look at the humble time clock.

Elliot was of at Europe's largest hacker convention: Chaos Communication Congress. He had an awesome time, saw more projects than you might think humanely possible, and got the flu. But he pulled through and put this audio tourbook for you. So if you've never been to CCC, give it a listen!

The entire Hackaday crew wishes you happy holidays and a fantastic 2026. You'll hear back from us then, so stay tuned.

This week's Hackaday Podcast sees Elliot Williams joined by Jenny List for an all-European take on the week, and have we got some hacks for you! In the news this week is NASA's Maven Mars Orbiter, which may sadly have been lost. A sad day for study of the red planet, but at the same time a chance to look back at what has been a long and successful mission. In the hacks of the week, we have a lo-fi camera, a very refined Commodore 64 laptop, and a MIDI slapophone to entertain you, as well as taking a detailed look at neutrino detectors. Then CYMK printing with laser cut stencils draws our attention, as well as the arrival of stable GPIB support for Linux. Finally both staffers let loose; Elliot with an epic rant about spreadsheets, and Jenny enthusiastically describing the Haiku operating system.

Hackaday Editors Elliot Williams and Al Williams met up to cover the best of Hackaday this week, and they want you to listen in. There were a hodgepodge of hacks this week, ranging from home automation with RF, volumetric displays in glass, and some crazy clocks, too. Ever see a typewriter that uses an ink pen? Elliot and Al hadn't either. Want time on a supercomputer? It isn't free, but it is pretty cheap these days. Finally, the guys discussed how to focus on a project like Dan Maloney, who finally got a 3D printer, and talked about Maya Posch's take on LLM intelligence.

Join Hackaday Editors Elliot Williams and Tom Nardi as they go over their picks for the best stories and hacks from the previous week. Things start off with a warning about the long-term viability of SSD backups, after which the discussion moves onto the limits of 3D printed PLA, the return of the Pebble smart watch, some unconventional aircraft, and an online KiCad schematic repository that has plenty of potential. You'll also hear about a remarkable conference badge made from e-waste electronic shelf labels, filling 3D prints with foam, and a tiny TV powered by the ESP32. The episode wraps up with our wish for hacker-friendly repair manuals, and an interesting tale of underwater engineering from D-Day.

This week, Hackaday's Elliot Williams and Kristina Panos met up over coffee to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous seven days or so. On What's That Sound, Kristina got sort of close, but of course failed spectacularly. Will you fare better and perhaps win a Hackaday Podcast t-shirt? Mayhap you will. After that, it's on to the hacks and such, beginning with an interesting tack to take with a flat-Earther that involves two gyroscopes. And we take a look at the design requirements when it comes to building synths for three-year-olds. Then we discuss several awesome hacks such as a vehicle retrofit to add physical heated seat controls, an assistive radio that speaks the frequencies, and an acoustic radiometer build. Finally, we look at the joys of hacking an old Kindle, and get a handle on disappearing door handles.

Wait, what? Is it time for the podcast again? Seems like only yesterday that Dan joined Elliot for the weekly rundown of the choicest hacks for the last 1/52 of a year. but here we are. We had quite a bit of news to talk about, including the winners of the Component Abuse Challenge -- warning, some components were actually abused for this challenge. They're also a trillion pages deep over at the Internet Archive, a milestone that seems worth celebrating. As for projects, both of us kicked things off with "Right to repair"-adjacent topics, first with a washing machine that gave up its secrets with IR and then with a car that refused to let its owner fix the brakes. We heated things up with a microwave foundry capable of melting cast iron -- watch your toes! -- and looked at a tiny ESP32 dev board with ludicrously small components. We saw surveyors go to war, watched a Lego sorting machine go through its paces, and learned about radar by spinning up a sonar set from first principles. Finally, we wrapped things up with another Al Williams signature "Can't Miss Articles" section, with his deep dive into the fun hackers can have with the now-deprecated US penny, and his nostalgic look at pneumatic tube systems.

It's a wet November evening across Western Europe, the steel-grey clouds have obscured a rare low-latitude aurora this week, and Elliot Williams is joined by Jenny List for this week's podcast. And we've got a fine selection for your listening pleasure! The 2025 Component Abuse Challenge has come to an end, so this week you'll be hearing about a few of the entries. We've received an impressive number, and as always we're bowled over by the ingenuity of Hackaday readers in pushing parts beyond their limits. In the news is the potential discovery of a lost UNIX version in a dusty store room at the University of Utah, Version 4 of the OS, which appeared in 1973. Check out your own stores, for hidden nuggets of gold. In the hacks, we have two cameras at the opposite end of the resolution spectrum, but sharing some impressive reverse engineering. Mouse cameras and scanner cameras were both a thing a couple of decades ago, and it's great to see people still pushing the boundaries. Then we look at the challenge of encoding Chinese text as Morse code, an online-upgraded multimeter, the art of making lenses for an LED lighting effect, and what must be the best recreation of a Star Wars light sabre we have ever seen. In quick hacks we have a bevvy of Component Abuse Challenge projects, a Minecraft server on a smart light bulb, and a long term test of smartphone battery charging techniques. We round off with a couple of our long-form pieces, first the uncertainties about iRobot's future and what it might mean for their ecosystem -- think: cheap hackable robotics platform! -- and then a look at FreeBSD as an alternative upgrade path for Windows users. It's a path not without challenges, but the venerable OS still has plenty to give. As always, check out the links to all the articles over on Hackaday.

Hackaday Editors Tom Nardi and Al Williams spent the weekend at Supercon and had to catch up on all the great hacks. Listen in as they talk about their favorites. Plus, stick around to the end to hear about some of the highlights from their time in Pasadena. If you're still thinking about entering the Component Abuse Contest, you're just about out of time. Need some inspiration? Tom and Al talk about a few choice entries, and discuss how pushing parts out of their comfort zone can come in handy. Do you make your own PCBs? With vias? If you have a good enough laser, you could. Or maybe you'd rather have a $10 Linux server? Just manage your expectations. The guys both admit they aren't mechanical geniuses and, unlike [4St4r], aren't very good at guessing sounds either. They round up with some 3D printing projects and a collection of quick hacks.

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 seven days or so. In Hackaday news, OMG Supercon is almost here! And we just revealed the badge! In other news, we've still got a contest running. Read all about the 2025 Component Abuse Challenge, sponsored by DigiKey, and check out the contest page for all the details. On What's That Sound, Kristina failed spectacularly. Will you fare better and perhaps win a Hackaday Podcast t-shirt? Mayhap you will. After that, it's on to the hacks and such, beginning with a really cool entry into the Component Abuse Challenge wherein a simple transmission line is used to multiply a voltage. We watch as a POV globe takes to the skies, once it has enough motors. Then we discuss several awesome hacks such as an incredible desk that simulates beehive activity, a really great handheld PC build, and a Tinkercad twofer. Finally, we discuss the future of removable batteries, and the history of movable type.

It was Elliot and Dan on the podcast today, taking a look at the best the week had to offer in terms of your hacks. We started with surprising news about the rapidly approaching Supercon keynote; no spoilers, but Star Trek fans such as we who don't have tickets will be greatly disappointed. Elliot waxed on about taking the poop out of your prints, Dan got into a camera that adds a dimension to its images, and we both delighted in the inner workings of an air-powered squishy robot. Questions? We've got plenty. Is it possible to take an X-ray without an X-ray tube? Or X-rays, for that matter? Did Lucille Ball crack a spy ring with her fillings? Is Algol set to take over the world? What's inside a germanium transistor? How does a flipping fish say Happy Birthday? And how far down the Meshtastic rabbit hole did our own Tom Nardi fall? Tune in to find out the answers.
