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

When Elliot Williams and Al Williams compare their notes on the week in Hackaday, you know you'll get at least one or two bad puns. How bad? Tune in and find out.
 
This week, Tom Nardi visits several in-person events, and Elliot and Al talk about smart buttons, Itanium, ejecting things from a rocket, and the infinite pickle. Will Elliot build the coin flipper? Will Al use plasma at his next cookout? Hard to say.
 
For the can't miss articles, this week, Al swept the category with a post on splices and another on what human junk is still sitting on the moon.

Ep 367: Radioactive Weather, Continuous Pickles, and Moon Junk

It's the evening before publication, and a pair of Hackaday writers convene to record the week's podcast. This week Elliot Williams is joined by Jenny List, and it's a bumper episode!
 
Of course, a bit of Hackaday news makes the cut, as it's time to make an entry in the Green Powered Challenge. Then we make the first of a couple of sojourns into AI, as we talk about the Linux kernel stance on AI code. In short: if you submit AI code you're responsible for its bugs. Meanwhile out of this world, we look forward to a time when astronauts breathe oxygen from moon dust.
 
There are hacks aplenty for your enjoyment, starting with far more than you ever thought it was possible to know about sound-reactive LED strips. Then we have among others a Mac on an ESP32 forming the UI for a weather monitor, Doom on a toaster, and a fascinating look at screw threads for plastic.
 
In the longer reads we have our colleague [Tom Nardi] finding Chinese people's personal data on hard drives he bought in an electronics store, and an attempt to look at what an LLM can do that might be useful. Grab your headphones, and join us!

Ep 366: DOOM on a Toaster, Music in LED Strips, and Old Drives in New Clothes

Humans flew around the Moon this week, but Hackaday Editors Elliot Williams and Tom Nardi were stuck on Earth -- luckily, there was no shortage of stories and hacks to keep them occupied. From the news that Linux might be putting the i486 out to pasture, to the fascinating potential of the threadless ball screw and connecting Bluetooth calipers up to FreeCAD. You'll hear about the latest in Internet via high-altitude balloon, the zen of organizing your parts bins, all the problems with Markdown files, and a deep-dive into making a convincing LED fire effect. The episode wraps up with some polarizing opinions on long term data storage, and a freewheeling discussion about the importance of literal moonshots.

Ep 365: Early 3DP Engineering, a New CAD Interface, and Flying Around the Moon

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, there's quite a bit to talk about. Regarding Hackaday Europe, you can rest assured that the talks will be announced soon. The Green-Powered Challenge is still 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!
 
As usual, we published a handful of April Fool's posts, which you may or may not find amusing. And finally -- no fooling -- our own Tom Nardi wrote up the Artemis moon launch, and is going to update the post every day until the mission ends.
 
On What's That Sound, we can score one for Kristina, which brings her record to approximately three wins and sixty-eight losses. She knew without a doubt that the dialogue was from the Day the Earth Stood Still (1951). Oh, what? There was a remake in 2008? Kristina should get bonus points, then.
 
After that, it's on to the hacks, beginning with the basics of making clean enclosures that are decidedly not 3D-printed, a couple of sweet lo-fi cameras, and a nice way to tame the tape when it comes to SMT parts. We also discuss a clock that marks time in a mathematical way, watch an electro-permanent magnet in action, and improving soda by turning it into mead. Finally, we discuss the solar balconies taking Europe by storm, and Copilot's terrifying terms of service.

Ep 364: Clocks, Cameras, and Free Will

What did Elliot Williams and Al Williams read on Hackaday last week? Tune in and find out. After a bit of news, [Vik Oliver] chimes in with some deep PLA knowledge. Then the topic changed to pressure advance measurements, SDRs, making super-resolution PCBs with a fiber laser, and more.
 
Want to 3D print wire strippers? A robot arm? Or just make your own Z-80? Those hacks are in there, too.
 
For the long articles, we talked about old tech, including the :CueCat and the Iomega Zip Drive. Let us know if you had either one in the comments.

Ep 363: The History of PLA, Laser DIY PCBs, and Corporate Craziness

As the sun goes down on a glorious spring evening on the western edge of Europe, Elliot Williams is joined by Jenny List for a look at the week in all things Hackaday.
 
First up: Hackaday Europe tickets are on sale! Bad luck folks, the early bird tickets disappeared in an instant, but regular ones are still available for now. We're really looking forward to making our way to Lecco for a weekend of hacks, and it would be great to see you there too.
 
Then we have a new feature for the podcast, the Hackaday Mailbag. This week's contribution comes from [Kenny], a longtime friend of Hackaday and probably our most regular conference attendee.
 
To the hacks, and we have some good ones. An air hockey robot might not seem like a challenge, but the engineering which went into [BasementBuilds'] one proves it's not a job for the faint hearted. Then we look at compression molding of recycled plastic using 3D-printed molds, something that seems surprisingly accessible and we'd like to try, too. We've got a new DOS, a 3D-printed zipper repair, the IPv4 replacement we didn't get, and the mind-bending logic of ternary computing. It's one of those weeks where the quick hacks could all deserve their own in-depth look, but perhaps the stand-outs are and Arduino style compiler that includes the source code compressed within the binary, and a beautifully-done revival of a 1980s brick cellphone as a modern 5G unit.
 
Finally in the longer reads we've got an examination of wired versus Bluetooth headphones -- we're both in the wired camp -- and a look back at the age of free dialup. As is so often the case, the experience there differed between Brits and Americans. Anyway, enjoy the episode, and we have another week to look forward to.

Ep 362: Compression Molding, IPv4x, and Wired Headphones

Join Hackaday Editors Elliot Williams and Tom Nardi as they cover their favorite hacks and stories from the week. The episode kicks off with some updates about Hackaday Europe and the recently announced Green Power contest, as well as the proposal of a new feature of the podcast where listeners are invited to send in their questions and comments. After the housekeeping is out of the way, the discussion will go from spoofing traffic light control signals and the line between desktop computers and smartphones, all the way to homebrew e-readers and writing code with chocolate candies. You'll hear about molding replacement transparent parts, a collection of fantastic tutorials on hardware hacking and reverse engineering, and the recent fireball that lit up the skies over Germany. The episode wraps up with a fascinating look at how the developer of Pokemon Go is monetizing the in-game efforts of millions of players.

Ep 361: Hackaday Podcast Mailbag, A Phone is Not a Computer, 3D Printing History is New Again

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.
