Another all-European podcast for you this week, as Elliot Williams is joined by Jenny List for an evening looking at the past week in Hackaday. And this week there is a particularly good selection to look at. A while back we showed you a project that put synthetic aperture radar on a drone, generating extremely detailed imaging of the terrain beneath it. This week we had an update, in which an ingenious positioning accuracy fix gave it an astonishing increase in resolution. On top of that project we

This week, Hackaday Editors Elliot Williams and Al Williams had a lot to talk about. From advice for a young hacker to using a laser to break into a microcontroller, there was plenty to cover from the week in Hackaday. From the "Point/Counter Point" department, there were dueling posts about how big a deal it is for Raspberry Pi to lock out RAM chip swapping. Ever want to do interactive debugging in MicroPython? For intellectual exercise, there's the physics of raindrops becoming a radar antenna. If

This week, Hackaday Editors Elliot Williams and Tom Nardi start the episode off by discussing the latest CircuitPython developments before covering some impressive reverse engineering efforts, the benefits of modeling your projects in 3D, and some of the most incredible timepieces that have ever graced the pages of Hackaday. You'll also hear about the fascinating potential of combing 3D and UV printing, Linux on the ESP32, and a virtual TV station that pulls from the Internet Archive. The episode

In this specially-numbered podcast episode that lines up quite nicely with our Retrocomputing Challenge, Elliot Williams and Kristina Panos met over surprisingly low-latency and loud beverages to bring you the best of the previous week's hacks. But first, the news. German company Isar Aerospace can now claim that they've launched the first spacecraft into orbit from Europe. Be sure to check out the in-link, where we reported on the building of the spaceport. In Hackaday news, the aforementioned

As the calendar turns a leaf into September, Elliot Williams is joined by Jenny List for our weekly look at all things Hackaday. In the news, our retrocomputing competition is well under way, but there's plenty of time to get an entry in if you've got a cool old-style project to show us. And then Elliot's been chasing seismic surveyors in Munich, where they're looking for geothermal energy. In the stand-out hacks there's a discussion of smoothing 3D prints using frickin' lasers, the effect of

What did Hackaday editors Elliot Williams and Al Williams read in Hackaday last week? Probably everything, but you can tune in and hear about their favorites on this week's podcast. They heard from lots of listeners this week, and also saw DIY projects running from a 3D-printed Stirling engine, to clogs, to LEDs. There are some over-the-top hacks like a refit for a decades-old watch to do tap-to-pay and a -- for lack of a better word -- a record player that optically reads MOD files. Want to emulate

In this week's episode, Hackaday Editors Elliot Williams and Tom Nardi start things off by getting excited about the recently announced 2026 Retrocomputing Challenge. From there the conversation will cover efforts to improve desktop 3D printing with lasers, an expensive grill with an ESP32 controller and an open source firmware, open source tools underground, and some impressive techniques to squeeze a bit more utility out of the common QR code. You'll also hear about turning PVC pipes into flat

It's still hot on both sides of the Atlantic, but Kristina has a new secret weapon for staying cool without making noise. Will Elliot and the others follow suit? Time will tell. In Hackaday news, well, there's a lot of it. For starters, Supercon Ten tickets went on sale Thursday morning, but chances are good that by the time you read this, the early bird offering will be all pecked out. But, never fear! More tickets will be released soon enough. Don't want to buy a ticket, but still want to go

This week's Hackaday podcast is a European affair again, as Elliot Williams is joined by Jenny List on a summer evening to review the week. And we have a feast of hacks for your delectation. As the title above says, one of the stand-out hacks this week was a set of airless mountain bike tyres 3D printed in glorious fluorescent TPU. They look as though they shouldn't work but in fact they showed real promise, and we discuss the process behind their design. Then we take a look at a hybrid of a UV

Elliot Williams and Al Williams got together to compare notes on the most interesting posts this week on the site. As usual, there are just too many choices, so you'll have to settle for just the few that can fit in a podcast. The guys were excited about 3D printing -- both FDM and SLA -- as well as a few camera projects. Ever wanted your own starship? They do, too, and you'll hear about it along with portable radar and more. Want to make flexible PCBs? Fill up a carbon dioxide tank? Or play Doom

On this episode, Hackaday editors Elliot Williams and Tom Nardi discuss their love of electronic paper, clunky cartridges, and keeping old games alive by any means possible. You'll also hear about getting the most out of the sensors in our 3D printers, playing with X-rays at home, a ring that runs Java, and a roulette wheel that outgrew its 555 timer. Stick around to the end to learn about a different sort of IRC that's even more niche than the one you're probably familiar with, as well as the

It's a hot one at both microphones, as Elliot Williams and Kristina Panos wilt in the heat with ice lollies and freezer packs. But still, we persevered long enough to make a podcast. In Hackaday news, Supercon is on! It's going down in Pasadena, California, but the talks will be somewhere slightly larger, with a courtyard instead of an alley. Get your talk proposals in now! In other Hackaday news, we still have our Frikkin' Lasers Contest going on until Thursday, July 23rd. Interestingly enough, we

This week's podcast sees Elliot joined by Jenny List, as both suffer silently in the European summer heat as the sound of a desk fan would come over on the recording. The stand-out hack of the week comes from [Bitluni], whose GPU made from thousands of cheap microcontrollers is on a scale we've never seen before. It's an amazing project in itself, but the manufacturing and power consumption issues of so many processors running at the same time make for a discussion of their own. Otherwise, we have

Hackadya's Elliot Williams and Al Williams were in a retro mood this week. There was a new '486 computer, a new mechanical TV, and a USB stick with a magnetic personality. Can you watch YouTube on a Game Boy? Maybe. For the can't miss articles, this week, Elliot and Al reflected on the awkward phase of 3D printers when they transformed from being expensive commercial machines, to where they are now. Meanwhile, Al was interested in how airplanes know how fast they are going. Along the way, there were

The discussion moves on to hacking bike counter, homebrew upgrades to the Nintendo Entertainment System, and building RAM from whats in the parts bin.

Not only do we have a triple mailbag this week, we have another failed attempt at guessing the sound by Kristina.

Last week, Elliot got his foot stepped on by a 1.5 metric ton draft horse, and boy is he glad to be back to the relative safety of podcasting! Joining him today is Jenny List, no stranger to farm life, who has been trodden by a cow. It's going to be one of those podcasts, folks. Another thing the two hosts have in common is a love for the mystery of the numbers station.

In Hackaday news, we have a new Frikkin' Lasers Challenge going on now, although we acknowledge that no one can actually enter their project into it at the moment. We hope to have that fixed in short order. Procrastinators, disregard. You'll have to wait another week for the triumphant return of What's That Sound, but we do have an audio mailbag for

They'll start off by reading some listener messages before talking about the slow extinction of time broadcasts, Linux on cheap smartphones, microcontroller VPNs, and the computers of Spacelab.

With Elliot back from Hackaday Europe, he and Al Williams had a lot to talk about with two weeks of Hackaday posts to catch up on. Not to mention the mailbag was overflowing. This week, the guys look at girlie cyberdecks, a 3D printed circuit board, and talk electric motorcycles. Is 3D printing safe? Want an accurate moon on your desk? How about modern punch cards? All of that and much more were on the menu this week. For the can't miss articles, Zoe Skyforest weighs in on file sharing on the LAN
