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

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.

2025 Holiday Placeholder Edition

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.

Ep 350: Damnation for Spreadsheets, Praise for Haiku, and Admiration for the Hacks In Between

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.

Ep 349: Clocks, AI, and a New 3D Printer Guy

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.

Ep 348: 50 Grams of PLA Hold a Ton, Phreaknic Badge is Off The Shelf, and Hackers Need Repair Manuals

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.

Ep 347: Breaking Kindles, Baby's First Synth, and Barcodes!

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.

Ep 346: Melting Metal in the Microwave, Unlocking Car Brakes and Washing Machines, and a Series of Tubes

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.

Ep 345: A Stunning Lightsaber, Two Extreme Cameras, and Wrangling Roombas

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.
