Ep 299: Beaming Consciousness, Understanding Holograms, and Dogfooding IPv6
On this episode of the Hackaday Podcast, Editors Elliot Williams and Tom Nardi talk about the optical witchcraft behind holograms, the finer points of designing 3D printable threads, and the challenges of switching your local network over to IPv6. They'll also cover how a clever software patch improves the graphics in a flight simulator from the 1990s, and why spacecraft flying into orbit powered by the SABRE engine is going to remain a dream for now. From there you'll hear about a reproduction VW gas gauge that works better than the real thing, custom ball screws, and the latest and greatest in homebrew battery charging. Finally, they'll cap the episode off by exploring the conundrum that's heating up London's Underground, and diving into the (mostly) fictional history of teleportation.

Ep 298: Forbidden USB-C, a Laser Glow-o-Scope, the Epoch Super Cassette Vision
This week's Hackaday podcast has a European feel, as Elliot Williams is joined by Jenny List for a look at the week's happenings in the world of cool hardware hacks. Starting with the week's news, those Redbox vending machines continue to capture the attention of hackers everywhere, and in the race to snag one before they're carted off for recycling someone has provided the missing hardware manual in the form of a wiki. Europeans can only look on wistfully. Then there's the curious case of life on the asteroid sample, despite the best efforts of modern science those pesky earth bacteria managed to breach all their anti-contamination measures. Anyone who's had a batch of homebrew go bad feels their pain. The week provided plenty of hacks, with the team being wowed by [Bitluni]'s CRT-like laser projector, then the many ingenious ways to 3D-print a hinge, and perhaps one of the most unforgiving environments in the home for a piece of robotics. Meanwhile our appetite for cool stuff was sated by an entire family of Japanese games consoles we'd never heard of, and the little voltage reference whose data sheet also had an audio amplifier circuit. Finishing up, our colleague Arya has many unorthodox uses for a USB-C cable, and we have a frank exchange of views about Linux audio. Check out all the links, and by all means, give us a roasting in the comments!

Ep 297: Prusa Eschews Open Source Hardware, The Lemontron Prints Upside-Down, and the vecdec Cyberdeck Does Minority Report
This week features exciting reveals from the Electronica trade show, including the Raspberry Pi Compute Module 5 and the stable launch of FreeCAD 1.0. The conversation dives into the shift away from open-source principles by a major 3D printing company. Innovative tech projects are showcased, like a printer that works upside-down and a stylish cyberdeck with advanced features. Retro nostalgia takes a turn with a quirky cyberpunk pocket watch, and the hosts explore the unique world of man-made kalthamites.

Ep 296: Supercon Wrapup with Tom and Al, The 3DP Brick Layering Controversy, and How To Weld in Space
In this episode you'll get to hear not one, not two, but three Hackaday Editors! Now that the dust has mostly settled from the 2024 Hackaday Supercon, Al Williams joins Elliot and Tom to compare notes and pick out a few highlights from the event. But before that, the week's discussion will cover the questionable patents holding back a promising feature for desktop 3D printers, a new digital book from NODE, and the surprisingly limited history of welding in space. You'll also hear about the challenge of commercializing free and open source software, the finicky optics of the James Web Space Telescope, and the once exciting prospect of distributing software via pages of printed barcodes.

Ep 295: Circuit Graver, Zinc Creep, and Video Tubes
With Superconference 2024 in the books, Dan joined Elliot, fresh off his flight back from Pasadena, to look through the week (or two) in hacks. It was a pretty good crop, too, despite all the distractions and diversions. We checked out the cutest little quadruped, a wireless antenna for wireless communications, a price-tag stand-in for paper calendars, and a neat way to test hardware and software together. We take the closest look yet at why Arecibo collapsed, talk about Voyager's recent channel-switching glitch, and find out how to put old Android phones back in action. There's smear-free solder paste application, a Mims-worthy lap counter, and a PCB engraver that you've just got to see. We wrap things up with a look at Gentoo and pay homage to the TV tubes of years gone by -- the ones in the camera, for the TV sets.

Ep 294: SAO Badge Reveal, Precision on a Shoestring, and the Saga of Redbox
With the 2024 Hackaday Supercon looming large on the horizon, Editors Elliot Williams and Tom Nardi start this episode off by talking about this year's badge and its focus on modular add-ons. From there they'll go over the results of a particularly challenging installment of What's that Sound?, discuss a promising DIY lathe that utilizes 3D printed parts filled with concrete, and ponder what the implosion of Redbox means for all of their disc-dispensing machines that are still out in the wild. You'll also hear about custom macropads, lifting SMD pins, and how one hacker is making music with vintage electronics learning kits. Finally, they'll reassure listeners that the shifting geopolitical landscape probably won't mean the end of Hackaday.io anytime soon, and how some strategically placed pin headers can completely change how you approach designing your own PCBs.

Ep 293: The Power of POKE, Folding Butterflies, and the CRT Effect
This week on the Podcast, Hackaday's Elliot Williams and Kristina Panos joined forces to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous week. First up in the news: we've extended the 2024 Supercon Add-On contest by a week! That's right, whether you were held up by Chinese fall holidays or not, here's your chance to get in on this action. We love to see the add-ons people make for the badge every year, so this time around we're really embracing the standard. The best SAOs will get a production run and they'll be in the swag bag at Hackaday Europe 2025. What's That Sound pretty much totally stumped Kristina once again, although she kind of earned a half shirt. Can you get it? Can you figure it out? Can you guess what's making that sound? If you can, and your number comes up, you get a special Hackaday Podcast t-shirt. Then it's on to the hacks, beginning with what actually causes warping in 3D prints, and a really cool display we'd never heard of. Then we'll discuss the power of POKE when it comes to live coding music on the Commodore64, and the allure of CRTs when it comes to vintage gaming. Finally, we talk Hackaday comments and take a look at a couple of keyboards.

Ep 292: Stainless Steel Benchies, Lego Turing Machines, and a Digital Camera Made of Pure DIY
Here we are in October, improbably enough, and while the leaves start to fall as the goblins begin to gather, Elliot and Dan took a break from the madness to talk about all the wonderful hacks that graced our pages this week. If there was a theme this week, it was long-term projects, like the multiple years one hacker spent going down dead ends in the quest for DIY metal 3D printing. Not to be outdone, another hacker spent seven years building a mirrorless digital camera that looks like a commercial product. And getting a solderless PCB to do the blinkenlight thing took a long time too. Looking to eliminate stringing in your 3D prints? Then you'll want to avoid the "pause and attach" approach, which intentionally creates strings in your prints. Wondering if you can 3D print bearings? You can, but you probably shouldn't unless you have a particular use in mind. And what happens when you have an infinitely large supply of Lego? Why, you build a Turing machine on steroids, of course. Finally, we take a look at this week's "Can't-Miss" articles with a look into plastic recycling and why we can't have nice things yet, and we take a trip out into orbit and examine the ins and outs of Lagrange points. And a little mea culpa from the editing desk: Sorry the podcast is coming out late this week. Audacity ate my files. If you're ever in a similar circumstance, you can probably halfway save your bacon with audacity-project-tools. Ask me how I know. Check out the links over at Hackaday.

Ep 291: Walking in Space, Lead in the Earth, and Atoms under the DIY MIcroscope
What have you missed on Hackaday this week? Elliot Williams and Al Williams compare notes on their favorites from the week, and you are invited. The guys may have said too much about the Supercon badge this year -- listen in for a few hints about what it will be about. For hacks, you'll hear about scanning tunneling microscopes, power management for small Linux systems, and lots of inertial measurement units. The guys talked about a few impossible hacks for consumer electronics, from hacking a laptop, to custom cell phones. Of course, there are plenty more long-form articles of the week, including a brief history of what can go wrong on a spacewalk and how to get the lead out (of the ground). Don't forget to take a stab at the What's That Sound competition and maybe score a sweet Hackaday Podcast T-shirt.

Ep 290: iPhone's Electric Glue, Winamp's Source Code, and Sonya's Beautiful Instructions
This week, Hackaday Editors Elliot Williams and Tom Nardi start things off by acknowledging an incredible milestone: 20 years of Hackaday! Well, probably. When a website gets to be this old, it's a little hard to nail down when exactly things kicked off, but it seems like September of 2004 is about right. They'll also go over the latest updates for the fast-approaching Hackaday Supercon, and announce the winner of another tough What's That Sound challenge. From there, the conversation makes its way from the fascinating electrically-activated adhesive holding the latest iPhone together to pulsed-power lasers and a high flying autonomous glider designed and built by a teenager. You'll also hear about 3D printing on acrylic, home biohacking, and the Tiny Tool Kit Manifesto. Stick around to the end to hear the duo discuss the fine art of good documentation, and an incredible bodge job from Arya Voronova.
