Hackaday

Hackaday Editors take a look at all of the interesting uses of technology that pop up on the internet each week. Topics cover a wide range like bending consumer electronics to your will, designing circuit boards, building robots, writing software, 3D printing interesting objects, and using machine tools. Get your fix of geeky goodness from new episodes every Friday morning.

Hackaday Podcast

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?

Ep 359: Flying Squids, Edible Passwords, and a CAD Automaton

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.

Ep 358: Soft Displays, LCD Apertures, and Mind Controlled Toys

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.

Ep 357: BreezyBox, Antique Tech, and Defusing Killer Robots

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.

Ep 356: Nanoprinting, Vibe Coding, and Keebin' with Kristina, IN HELL!

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!

Ep 355: Person Detectors, Walkie Talkies, Open Smartphones, and a WiFi Traffic Light

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.

Ep 354: Firearms, Sky Driving, and Dumpster Diving

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.

Ep 353: Fantastic Peripherals, Fake or Not Fake Picos, and Everything on the Steam Deck

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.

Ep 352: Visualizing Sound, and Windows 11 Is a Dog

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!

Ep 351: Hackaday Goes To Chaos Communication Congress

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