Ep 287: Raspberry Pi Woes, Blacker than Black, and Printing with Klipper Sep 06, 2024

Show notes

Elliot Williams is back from vacation, and he and Al Williams got together to talk about the best Hackaday posts from the last week. Of course, the Raspberry Pi RP2350 problem generated a bit of discussion.

On a lighter note, they saw laser lawn care, rooting WiFi devices, and some very black material made from wood. Need more current-sinking capability from a 555? They talked about that, too, along with a keyboard you use with your feet.

The guys had a lot to say about Klipper, why you might want to move your 3D printer to it, and the FCC's stance on ham radio antennas in restricted neighborhoods. Oh, and don't forget to play "What's that Sound?"

Ep 286: Showing off SAOs, Hiding from HOAs, and Beautiful Byproducts Aug 30, 2024

Show notes

Even when the boss is away, the show must go on, so Dan slid back behind the guest mic and teamed up with Tom to hunt down the freshest of this week's hacks. It was a bit of a chore, with a couple of computer crashes and some side-quests down a few weird rabbit holes, but we managed to get things together in the end.

Tune in and you'll hear us bemoan HOAs and celebrate one ham's endless battle to outwit them, no matter what the golf cart people say about his antennas. Are you ready to say goodbye to the magnetic stripe on your credit card? We sure are, but we're not holding our breath yet. Would you 3D print a 55-gallon drum? Probably not, but you almost can with a unique Cartesian-polar hybrid printer. And, if you think running MS-DOS on a modern laptop is hard, guess again -- or, maybe you just have to get really lucky.

We also took a look at a digital watch with a beautiful display, a hacked multimeter, modern wardriving tools, switchable magnets, and debate the eternal question of v-slot wheels versus linear bearings. And finally, you won't want to miss our look at what's new with 3D scanning, and the first installment of Kristina's new "Boss Byproducts" series, which delves into the beauty of Fordite.

Ep 285: Learning Laser Tricks, Rocket Science, and a Laptop That's Not a Laptop Aug 23, 2024

Show notes

This week on the Podcast, we have something a little different for you. Elliot is on vacation, so Tom was in charge of running the show and he had Kristina in the hot seat.

First up in the news: the 2024 Tiny Games Challenge is still underway and has drawn an impressive 44 entries as of this writing. You have until 9AM PDT on September 10th to show us your best tiny game, whether that means tiny hardware, tiny code, or a tiny BOM.

Then it's on to What's That Sound, which Tom and Kristina came up with together, so there will be no pageantry about guessing. But 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.

Now it's on to the hacks, beginning with an open-source liquid-fueled rocket and a really cool retro trackball laptop. Then we'll discuss screwdriver mange, the Wow! signal, and whether you're using you're calipers incorrectly. Finally, we look at a laptop that that isn't really a laptop, and one simple trick to keep things aligned on your laser engraver.

Ep 284: Laser Fault Injection, Console Hacks, and Too Much Audio Aug 16, 2024

Show notes

The summer doldrums are here, but that doesn't mean that Elliot and Dan couldn't sift through the week's hack and find the real gems. It was an audio-rich week, with a nifty microsynth, music bounced off the moon, and everything you always wanted to know about Raspberry Pi audio but were afraid to ask. We looked into the mysteries of waveguides and found a math-free way to understand how they work, and looked at the way Mecanum wheels work in the most soothing way possible.

We also each locked in on more classic hacks, Elliot with a look at a buffer overflow in Tony Hawks Pro Skater and Dan with fault injection user a low-(ish) cost laser setup. From Proxxon upgrades to an RC submarine to Arya's portable router build, we've got plenty of material for your late summer listening pleasure.

Ep 283: Blinding Lasers, LEDs, and ETs Aug 09, 2024

Show notes

Hackaday Editors Elliot Williams and Al Williams reflect on the fact that, as humans, we have--at most--two eyes and no warp drives. While hacking might not be the world's most dangerous hobby, you do get to work with dangerous voltages, temperatures, and frickin' lasers. Light features prominently, as the guys talk about LED data interfaces, and detecting faster-than-light travel.

There's also a USB sniffer, abusing hot glue, and some nostalgia topics ranging from CRT graphics to Apollo workstations (which have nothing directly to do with NASA). The can't miss articles this week cover hacking you and how you make the red phone ring in the middle of a nuclear war.

Ep 282: Saildrones, a New Classic Laptop, and SNES Cartridges are More Than You Think Aug 02, 2024

Show notes

In this episode, the CrowdStrike fiasco has Hackaday Editors Elliot Williams and Tom Nardi pondering the fragility of our modern infrastructure. From there the discussion moves on to robotic sailboats, the evolving state of bespoke computers, and the unique capabilities of the Super Nintendo cartridge. You'll also hear about cleaning paintings with lasers, the advantages of electronic word processors, stacking 3D printed parts, and the joys of a nice data visualization. They'll wrap the episode up by marveling at the techniques required to repair undersea fiber optic cables, and the possibilities (and frustrations) of PCB panelization using multiple designs.

Ep 281: Metal Clay, Desiccants, Silica Gel, and Keeping Filament Dry Jul 26, 2024

Show notes

This week on the Podcast, it's Kristina's turn to bloviate alongside Editor-in-Chief Elliot Williams. First up in the news: our fresh new contest has drawn three entries already! That's right, the 2024 Tiny Games Challenge is underway. You have until September 10th to show us your best tiny game, whether that means tiny hardware, tiny code, or a tiny BOM.

Then it's on to What's That Sound, which sounded familiar to Kristina, but she couldn't place it. 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 a hack to print metal and a way to weld wood, along with a photo-resistor-based, single-pixel camera. We'll talk desiccants carbon fiber, and Baron Harkonnen. Finally, we discuss the troubles of keeping hygroscopic materials from degrading, and have a klatch about Keebin' with Kristina.

Ep 280: TV Tubes as Amplifiers, Smart Tech in Sportsballs, and Adrian Gives Us the Fingie Jul 19, 2024

Show notes

Despite the summer doldrums, it was another big week in the hacking world, and Elliot sat down with Dan for a rundown. Come along for the ride as Dan betrays his total ignorance of soccer/football, much to Elliot's amusement. But it's all about keeping the human factor in sports, so we suppose it was worth it.

Less controversially, we ogled over a display of PCB repair heroics, analyzed a reverse engineering effort that got really lucky, and took a look at an adorable one-transistor ham transceiver. We also talked about ants doing surgery, picking locks with nitric acid, a damn cute dam, and how to build one of the world's largest machines from scratch in under a century. Plus, we answered the burning question: can a CRT be used as an audio amplifier? Yes, kind of, but please don't let the audiophiles know or we'll never hear the end of it.

Ep 279: Solar Flares, Flash Cells, and Free Airline WiFi Jul 12, 2024

Show notes

Get your weekly fix of great hacks with your guides, Elliot Williams and Al Williams. This week, the guys talk about hacking airline WiFi, vanishing cloud services, and hobbies adjacent to hacking, such as general aviation. Things go into the weird and wonderful when the topic turns to cavity filters, driving LEDs with a candle, and thermite.

Quick hacks? Everything from vintage automated telescopes to home fusion reactors and ham radio mobile from a bicycle. Then there's the can't miss articles about the Solar Dynamics Observatory and an explainer about flash memory technology.

Ep 278: DIY Subs, the ErgoRing, and Finding NEMA 17 Jul 05, 2024

Show notes

In this episode, Hackaday Editors Elliot Williams and Tom Nardi kick things off with a reminder about the impending deadline for Supercon talk and workshop proposals. From there discussion moves on to the absolutely incredible tale of two brothers who solved a pair of missing person cases with their homebrew underwater vehicle, false data sneaking into OctoPrint's usage statics, and an organic input device that could give the classic mouse a run for its money.

You'll also hear about cheap radar modules, open source Xbox mod chips, and lawnmowers from the grocery store. The episode wraps up with a look at the enduring mystique of perpetual motion devices, and the story of a legendary ship that might soon end up being turned into paper clips.
