S6 Ep 276Ep 276: A Mac on a Pico, Ropes on the Test Stand, A Battleship up on Blocks

The week gone by was rich with fun hacks, and Elliot and Dan teamed up this time around to run them down for everyone. The focus this week seemed to trend to old hardware, from the recently revived Voyager 1 to a 1940s car radio, a homebrew instrument from 1979, a paper tape reader, and a 128k Mac emulator built from an RP2040. Newer hacks include a 3D-printed bottle labeler, a very hackable smart ring, and lessons learned about programming robots. We also took a look at turning old cell phones into Linux machines, making sure climbing ropes don't let you down, and snooping on orbital junk with a cool new satellite. We wrapped things up with a discussion of just how weird our solar system is, and Dan getting really jealous about Tom Nardi's recent trip to see the battleship New Jersey from an up close and personal perspective.

S6 Ep 275Episode 275: Mud Pulse Telemetry, 3D Printed Gears in Detail, and Display Hacking in our Future

Join Hackaday Editors Elliot Williams and Tom Nardi for a review of the best stories to grace the front page of Hackaday this week. Things kick off with the news about Raspberry Pi going public, and what that might mean for everyone's favorite single-board computer. From there they'll cover the technology behind communicating through mud, DIY pressure vessels, pushing the 1983 TRS-80 Model 100 to its limits, and the reality of 3D printing how that the hype has subsided. You'll also hear about modifying Nissan's electric vehicles, bringing new life to one of the GameCube's oddest peripherals, and an unusually intelligent kayak. The episode wraps up with some interesting (or depressing) numbers that put into perspective just how much copper is hiding in our increasingly unused telephone network, and a look at how hardware hackers can bend the display technology that's used in almost all modern consumer electronics to our advantage.

S6 Ep 274Ep 274: Capstan Robots, Avionics of Uncertain Purpose, and What the Frack?

What do capstans, direct conversion receivers, and fracking have in common? They were all topics Hackaday editors Elliot Williams and Al Williams found fascinating this week. If you wonder what makes an electrical ground a ground, or what a theodolite is, you should check it out. Al struck on on the What's That Sound, but [Ferric Bueler] didn't so he scores a highly-coveted Hackaday Podcast T-Shirt. Want one? Tune in next week for your chance. This week, the hacks came fast and furious. Capstans, instead of gears, work well for 3D-printed mechanisms, a PI Pico can directly receive radio signals, and the guys saw a number of teardowns and reverse engineering triumphs. You'll also find solid-state heat pumps, flying wings, spectroscopy, and more. The can't miss articles this week? Learn about theodolites, a surveying feat from ancient Greece, and how fracking works. Head on over to Hackaday for the full links!

S6 Ep 273Ep 273: A Tube Snoot, Dynamic Button Blobs, and Tokamaks Aren't Whack

This week, it was Kristina's turn in the hot seat with Editor-in-Chief Elliot Williams. First up in the news: Germany's solar expansion and a lot of wind have resulted in excess energy, which some people think is bad. In Hackaday news, the entries in the 2024 Business Card Challenge are really stacking up. Then it's on to What's That Sound, which Kristina provided this week and managed to stump Elliot. 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 an improved spectrometer that wasn't easy, and a rotary phone kitchen timer that kind of was. We'll talk about badges turned invitations, reinventing rotary switches, and dynamic button blobs. Finally, we get the lowdown on the state of nuclear fusion, and posit why chatting online isn't what it used to be.

S6 Ep 272Ep 272: Desktop EDM, Silence of the Leaves, and the Tyranny of the Rocket Equation

With Elliot off on vacation, Tom and Dan made a valiant effort to avoid the dreaded "clip show" and provide you with the tastiest hacker treats of the week. Did they succeed? That's not for us to say, but if you're interested in things like non-emulated N64 games and unnecessarily cool filament sensors, this just might be one to check out. We also came across a noise suppressor for a leaf blower, giant antennae dangling from government helicopters, and a desktop-friendly wire EDM setup that just might change the face of machining. We waxed on about the difference between AI-generated code and just pulling routines from StackExchange, came to the conclusion that single-stage-to-orbit is basically just science fiction, and took a look at the latest eclipse from 80,000 feet, albeit a month after the fact.

S6 Ep 271Ep 271: Audio Delay in a Hose, Ribbon Cable Repair, and DIY Hacker Metrology

What did Hackaday Editors Elliot Williams and Al Williams find interesting on Hackaday this week? Well, honestly, all the posts, but they had to pick some to share with you in the podcast below. There's news about SuperCon 2024, and failing insulin pumps. After a mystery sound, the guys jump into reverbing garden hoses, Z80s, and even ribbon cable repair. Adaptive tech was big this week, with a braille reader for smartphones and an assistive knife handle. The quick hacks ranged from a typewriter that writes on toast to a professional-looking but homemade ham radio transceiver.

S6 Ep 270Ep 270: A Cluster of Microcontrollers, a rocket engine from scratch, and a look inside Voyager

Join Hackaday Editors Elliot Williams and Tom Nardi as they get excited over the pocket-sized possibilities of the recently announced 2024 Business Card Challenge, and once again discuss their picks for the most interesting stories and hacks from the last week. There's cheap microcontrollers in highly parallel applications, a library that can easily unlock the world of Bluetooth input devices in your next project, some gorgeous custom flight simulator buttons that would class up any front panel, and an incredible behind the scenes look at how a New Space company designs a rocket engine from the ground up. Stick around to hear about the latest 3D printed gadget that all the cool kids are fidgeting around with, a brain-computer interface development board for the Arduino, and a WWII-era lesson on how NOT to use hand tools. Finally, learn how veteran Hackaday writer Dan Maloney might have inadvertently kicked off a community effort to digitize rare documentation for NASA's Voyager spacecraft.

S6 Ep 269Ep 269: 3D Printed Flexure Whegs, El Cheapo Bullet Time, and a DIY Cell Phone Sniffer

This week, it was Kristina's turn in the hot seat with Editor-in-Chief Elliot Williams. First up in the news -- the results are in for the 2024 Home Sweet Home Automation contest! First and second place went to some really gnarly, well-documented hacks, and third went to the cutest pill-dispensing robot you'll probably see before you hit the retirement home. Which was your favorite? Let us know in the comments. Then it's on to What's That Sound. Kristina failed once again, but you will probably fare differently. 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 DIY cell phone sniffer and a pen that changed the world. Then we talk bullet time on a budget, the beautiful marriage of 3D printing and LEGO, and, oh yes, flexure whegs. Finally, we get the lowdown on extender probes, and posit why it's hard to set up time zones on the Moon, relatively speaking.

S6 Ep 268Ep 268: RF Burns, Wireless Charging Sucks, and Barnacles Grow on Flaperons

Elliot and Dan got together to enshrine the week's hacks in podcast form, and to commiserate about their respective moms, each of whom recently fell victim to phishing attacks. It's not easy being ad hoc tech support sometimes, and as Elliot says, when someone is on the phone telling you that you've been hacked, he's the hacker. Moving on to the hacks, we took a look at a hacking roadmap for a cheap ham radio, felt the burn of AM broadcasts, and learned how to program old-school EPROMs on the cheap. We talked about why having a smart TV in your house might not be so smart, especially for Windows users, and were properly shocked by just how bad wireless charging really is. Also, cheap wind turbines turn out to be terrible, barnacles might give a clue to the whereabouts of MH370, and infosec can really make use of cheap microcontrollers.

S6 Ep 267Ep 267: Metal Casting, Plasma Cutting, and a Spicy 555

What were some of the best posts on Hackaday last week? Elliot Williams and Al Williams decided there were too many to choose from, but they did take a sampling of the ones that caught their attention. This week's picks were an eclectic mix of everything from metal casting and plasma cutters to radio astronomy and space telescope budgets. In between? Some basic circuit design, 3D printing, games, dogs, and software tools. Sound confusing? It won't be after you listen to this week's podcast.

S5 Ep 266Ep 266: A Writer's Deck, Patching Your Battleship, and Fact-Checking the Eclipse

Before Elliot Williams jumps on a train for Hackaday Europe, there was just enough time to meet up virtually with Tom Nardi to discuss their favorite hacks and stories from the previous week. This episode's topics include the potential benefits of having a dual-gantry 3D printer, using microcontrollers to build bespoke note taking gadgets, the exciting world of rock tumbling, and the proper care and maintenance required to keep your World War II battleship in shape. They'll also go over some old school keyboard technologies, DIP chip repairs, and documenting celestial events with your home solar array. By the end you'll hear about the real-world challenges of putting artificial intelligence to work, and how you can safely put high-power lithium batteries to work in your projects without setting your house on fire.

S6 Ep 265Ep 265: Behind the Epic SSH Hack, 1980s Cyber Butler, The Story of Season 7

This week, Editor-in-Chief Elliot Williams and Kristina Panos convened once again to give the lowdown on this week's best hacks. First up in the news -- it's giga-sunset time for Gigaset IoT devices, which simultaneously became paperweights on March 29th. And all that Flipper Zero panic? It has spread to Australia, but still remains exactly that: panic. Then it's on to What's That Sound. Kristina failed again, although she was in the right neighborhood. 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 the terrifying news of an xz backdoor. From there, we marvel at a 1980s 'butler in a box' -- a voice-activated home automation system -- and at the idea of LoRa transmissions without a radio. Finally, we discuss why you don't want to piss off Trekkies, and whether AI has any place in tech support.

S6 Ep 264Ep 264: Cheap Minimills, 65-in-1 Electronics, and Time on Moon

It was Dan's turn behind the mic with Elliot this time as we uncovered the latest from the world of hacking, and what an eclectic mix it was. It was slightly heavy on machining, with a look at mini-mills that are better than nothing, and a DIY DRO that's A-OK. We also kicked the nostalgia bucket over -- whatever that means -- and got a new twist on the old "65-in-1" concept, found hidden code in 80s music, and looked at color TV in the US and how it got that way. We've got ample alliteration about grep, thoughts about telling time on the Moon, and what does Canada have against the poor Flipper Zero, anyway? Head on over to Hackaday for all the linky-links.

S6 Ep 263Ep 263: Better DCMA, AI Spreadsheet Play, and Home Assistants Your Way

No need to wonder what stories Hackaday Editors Elliot Williams and Al Williams were reading this week. They'll tell you about them in this week's podcast. The guys revisit the McDonald's ice cream machine issue to start. This week, DIY voice assistants and home automation took center stage. But you'll also hear about AI chat models implemented as a spreadsheet, an old-school RC controller, and more. How many parts does it take to make a radio? Not a crystal radio, a software-defined one. Less than you might think. Of course, you'll also need an antenna, and you can make one from lawn chair webbing. In the can't miss articles, you'll hear about the problems with the x86 architecture and how they tried to find Martian radio broadcasts in the 1920s. Miss any this week?

S5 Ep 262Ep 262: Wheelchair Hacking, Big Little Science at Home, Arya Talks PCBs

Join Hackaday Editors Elliot Williams and Tom Nardi as they go over their favorite hacks and stories from the past week. This episode starts off with an update on Hackaday Europe 2024, which is now less than a month away, and from there dives into wheelchairs with subscription plans, using classic woodworking techniques to improve your 3D printer's slicer, and a compendium of building systems. You'll hear about tools for finding patterns in hex dumps, a lusciously documented gadget for sniffing utility meters, a rare connector that works with both HDMI and DisplayPort, and a low-stress shortwave radio kit with an eye-watering price tag. Finally, they'll take a close look at a pair of articles that promise to up your KiCAD game.

S6 Ep 261Ep 261: Rickroll Toothbrush, Keyboard Cat, Zombie Dialup

This week, Editor-in-Chief Elliot Williams and Kristina Panos met up in a new disposable location to give the lowdown on this week's best hacks. First up in the news -- the Home Sweet Home Automation contest is still going strong. You've still got plenty of time, so get on over to Hackaday.IO and start your entry today. In the news, the UK is asking how powerful an electric bike should be (more than 250 Watts, certainly), and legal pressure from Nintendo has shut down two emulators. Then it's on to What's That Sound. Kristina failed again, although she was pretty confident about her answer. Can you get it? Can you figure it out? Can you guess what's making that sound this week? If you can, and your number comes up, you get a special Hackaday Podcast t-shirt. But then it's on to the hacks, beginning with a Wi-Fi toothbrush hack from [Aaron Christophel]. This can only mean the beginning of some epic toothbrush firmware, right? From there, we marvel at moving cat food, the ultimate bulk material, and the idea of spoofing a whole cloud of drones. Finally, we examine one of Jenny's Daily Drivers in the form of Damn Small Linux (the other DSL), and reminisce about dial-up (speaking of DSL).

S6 Ep 260Ep 260: KiCad 8, Two Weather Stations, and Multiple I2Cs

It's a leap year, so Elliot and Dan put the extra day to good use tracking down all the hottest hacks from the past week and dorking out about them. There's big news in the KiCad community, and we talked about all the new features along with some old woes. Great minds think alike, apparently, since two different e-ink weather stations made the cut this week, as did a floating oscilloscope, an automated film-developing tank, and some DIY solar panels. We talked about a hacker who figured out that water makes a pretty good solar storage medium, and it's cheaper than lithium, another who knows that a crappy lathe is better than no lathe, and what every hacker should know about Ethernet. Is there a future for room-temperature superconductors? Maybe it just depends on how cold the room is. Check out the links over on Hackaday.

S6 Ep 259Ep 259: Twin-T, Three D, and Driving to a T

Hackaday Editors Elliot Williams and Al Williams sat down to compare notes on their favorite Hackaday posts of the week. You can listen in on this week's podcast. The guys talked about the latest Hackaday contest and plans for Hackaday Europe. Plus, there's a what's that sound to try. Your guess can't be worse than Al's, so take a shot. You could win a limited-edition T-shirt. In technical articles, Elliot spent the week reading about brushless motor design, twin-t oscillators, and a truly wondrous hack to reverse map a Nintendo Switch PCB. Al was more nostalgic, looking at the 555 and an old Radio Shack kit renewed. He also talked about a method to use SQL to retrieve information from Web APIs. Quick hacks were a decided mix with everything from homemade potentiometers to waterproof 3D printing. Finally, the guys talked about Hackaday originals. Why don't we teach teens to drive with simulators? And why would you want to run CP/M -- the decades-old operating system -- under Linux?

S6 Ep 258Ep 258: So Much Unix, Flipper Flip-out, and the Bus Pirate 5

Hackaday Editors Elliot Williams and Tom Nardi discuss all the week's best and most interesting hacks and stories, starting with Canada's misguided ban on the Flipper Zero for being too spooky. From there they'll look at the state-of-the-art in the sub-$100 3D printer category, Apple's latest "Right to Repair" loophole, running UNIX on the NES (and how it's different from Japan's Famicom), and the latency of various wireless protocols. After singing the praises of the new Bus Pirate 5, discussion moves on to embedded Linux on spacecraft, artfully lifting IC pins, and the saga of the blue LED. Finally you'll hear the how and why behind electrical steel, and marvel at a Mach 10 missile that (luckily) never needed to be used. Head on over to Hackaday and check out the links!

S6 Ep 257Ep 257: The Hacks and Just the Hacks

Last week, we held an Episode 256 celebration round-table, but Kristina and I also met afterwards to talk about all the week's hacks. That part didn't fit, but we didn't want to deprive you of your weekly hack fix either, so here they are!

Feb 14, 202421 min

S6 Ep 256Ep 256: 0, 256, 400, 100, and 10000000

For this week's episode, we did something super special -- we all convened to answer your burning questions about your hosts, both as hackers and as humans. We kick things off with a segment featuring a hearty round-table discussion between Elliot, Al, Dan, Kristina, and Tom. What's on our benches? What do we type on? Go find out! None of us figured out What's That Sound though a few of us had some creative guesses. Can you guess the sound? There could be a t-shirt in it for ya. Kristina and Elliot went on to have a normal podcast too, but since the round table section went so long, we'll process up that section and put it out early next week. Stay tuned!

Feb 9, 202441 min

S6 Ep 255Ep 255: Balloon on the Moon, Nanotech Goblets, and USB All the Way

This week, Dan joined Elliot for a review of the best and brightest hacks of the week in Episode 0xFF, which both of us found unreasonably exciting; it's a little like the base-2 equivalent of watching the odometer flip over to 99,999. If you know, you know. We had quite a bumper crop of coolness this week, which strangely included two artifacts from ancient Rome: a nanotech goblet of colloidal gold and silver, and a perplexing dodecahedron that ends up having a very prosaic explanation -- probably. We talked about a weird antenna that also defies easy description, saw a mouse turned into the world's worst camera, and learned how 3D-printed signs are a whole lot easier than neon, and not half bad looking either. As always, we found time to talk about space, like the legacy of Ingenuity and whatever became of inflatable space habitats. Back on Earth, there's DIY flux, shorts that walk you up the mountain, and more about USB-C than you could ever want to know. And don't forget that to celebrate Episode 256 next week, we'll be doing a special AMA segment where we'll get all the regular podcast crew together to answer your questions about life, the universe, and everything. If you've got a burning question for Elliot, Tom, Kristina, Al, or Dan, put it down in the comment section and we'll do our best to extinguish it.

S6 Ep 254Ep 254: AI, Hijack Guy, and Water Rockets Fly

This week Hackaday Editors Elliot Williams and Al Williams chew the fat about the Haier IOT problem, and all other top Hackaday stories of the week. Want to prove your prowess at C programming? Take a quiz! Or marvel at some hairy display reverse engineering or 3D-printed compressor screws. On the lighter side, there's an immense water rocket. After Al waxes nostalgic about the world of DOS Extenders and extended memory, the guys talk about detective work: First detecting AI-written material, and finally, a great detective story about using science to finally (maybe) crack the infamous DB Cooper hijacking case. Follow along with the links over at Hackaday. Don't forget to tell us what you think about this episode in the comments!

S6 Ep 253Ep 253: More Wood Robot, Glitching and Fuming Nitric Acid, We Heart USB-C

This week Hackaday Editors Elliot Williams and Tom Nardi start things off with a traffic report from the Moon, which has suddenly become a popular destination for wayward robots. [caption id="attachment_657278" align="alignright" width="300"] Anonymizing an ATtiny85 via laser[/caption] From there, they'll go over a fire-tending contraption that's equal parts madness and brilliance, two decades of routers being liberated by OpenWRT, impressive feats of chip decapping, and USB-C's glorious rise to power. You'll also hear about the latest developments in laptop RAM, exploits against the flash encryption used on the ESP32, and Android powered oscilloscopes. The duo will wrap things up with horror stories from the self-checkout aisle, and a look at the fantastical rolling power station that Dan Maloney has been building in his driveway.

S6 Ep 252Ep 252: X1Plus Hacks Bambu, Scotto Builds a Katana Keyboard, and Bass Puts out Fire

This week, Editor-in-Chief Elliot Williams and Kristina Panos met up to discuss the best hacks of the previous week. It's CES time once again in Las Vegas, and you know what that means -- some wacky technologies like this AI pet door that rejects dead mice. Then it's on to What's That Sound, which Kristina managed to nail for once. Can you get it? Can you figure it out? Can you guess what's making that sound this week? If you can, and your number comes up, you get a special Hackaday Podcast t-shirt. But then it's on to the hacks, beginning with a new keyboard from [Joe Scotto] and an exploration of all you can do with an LED strip, like 1D fireworks and roller coasters without any moving parts. From there, we marvel at the ability of sound waves to extinguish flames, and the tech behind life as a quadriplegic. Finally, we examine not one, but two of Jenny List's finely-crafted rants, one about web browsers, and the other about the responsible use of new technology.

S6 Ep 251Ep 251: Pluto, Pinball, Speedy Surgery, and DIY GPS

Welcome to 2024! This time around, Elliot and Dan ring in a new year of awesome hacks with quite an eclectic mix. We kick things off with a Pluto pity party and find out why the tiny ex-planet deserved what it got. What do you do if you need to rename a bunch of image files? You rope a local large-language model in for the job, of course. We'll take a look at how pinball machines did their thing before computers came along, take a fractal dive into video feedback, and localize fireworks with a fleet of Raspberry Pi listening stations. Ever wonder what makes a GPS receiver tick? The best way to find out might be to build one from scratch. Looking for some adventure? A ride on an electroluminescent surfboard might do, or perhaps a DIY "Vomit Comet" trip would be more your style. And make sure you stick around for our discussion on attempts to optimize surgery efficiency, and our look back at 2023's top trends in the hardware world. Check out all the links over at Hackaday!

S5 Ep 250Ep 250: Trains, RC Planes, and EEPROMS in Flames

This week in the Podcast, Elliot Williams is off at Chaos Communication Congress, hearing tales of incredible reverse engineering that got locomotives back up and running, while Al Williams is thinking over what happened in 2023. There's a lot of "how things work" in this show, from data buoys to sewing machines to the simulated aging of ICs. Whether you're into stacking bricks, stacking Pi Picos, or stacking your 3D prints to make better use of precious bed space, this episode is for you. Enjoy.

S5 Ep 249Ep 249: Data by Laser and Parachute, Bluetooth Hacks, Google's Gotta Google

'Twas the podcast before Christmas, and all through the house, the best hacks of the week are dancing around Elliot and Tom's heads like sugar-plums. Whatever that means. Before settling their brains in for a long winter's nap, they'll talk about the open source software podcast that now calls Hackaday home, the latest firmware developments for Google's Stadia controller, high-definition cat videos from space, and upgrades for the surprisingly old-school battery tech that powers the Toyota Prius. Out on the lawn, expect a clatter about the the state-of-the-art in DIY camera technology, the acoustic properties of hot chocolate, and a storage media from the 1990s that even Al Williams had never heard of. Finally, after tearing open the shutters and throwing up the sash, the episode wraps up with a discussion about wiring techniques that let you leave the soldering iron at home, and the newest chapter in the long history of transferring data via parachute. Miniature sleigh and eight tiny reindeer sold separately. Check out the links over on Hackaday.

S5 Ep 248Ep 248: Cthulhu Clock Radio Transharmonium, Thunderscan, and How to Fill Up in Space

This week, Elliot sat down with Dan for the penultimate podcast of 2023, and what a week it was. We started with news about Voyager; at T+46 years from launch, any news tends to be bad, and the latest glitch has everyone worried. We also took a look at how close the OSIRIS-REx mission came to ending in disaster, all for want of consistent labels. Elliot was charmed by a Cthulhu-like musical instrument, while Dan took a shine to a spark gap transmitter that's probably on the FCC's naughty list. Any sufficiently advanced technology is indistinguishably from magic, and we looked at the laser made possible by the magician-in-chief himself, C.V. Raman. Why would you stuff a PSU full of iron filings? Probably for the same reason you'd print fake markings on a 6502 chip. We also took a look at the chemistry and history of superglue, a paper tape reader that could lop off your arm, and rocket gas stations in space. How about checking out the links over at Hackaday? That's what we'd do.

S5 Ep 247Ep 247: Cameras From Gingerbread or Hardboard, and the Insecurity of Bluetooth

This week, Editor-in-Chief Elliot Williams and Kristina Panos met up to discuss the best hacks of the previous week. We have no nerdy news this week, but is that necessarily a bad thing? Speaking of nothingness, we have no winner for What's That Sound? because all six people who responded were wrong. Was the sound of Clippy too obscure? But then it's on to the hacks, beginning with an awesome autonomous excavator that, among other things, lays boulders algorithmically to build load-bearing walls without any mortar or cement. From there, it's old school meets new school in the form of a laser-cut fox-wedged mortise and tenon joint. We take a look at a couple of simple cameras, making dry ice from seashells, and a really tiny POV display where everything spins. Finally, we talk about how small that proposed Italian lunar outpost is, and discuss whether rating airlines would help stop the spread of diseases.

S5 Ep 246Ep 246: Bypassing Fingerprint Readers is Easy, Killing Memory Chips is Hard, Cell Phones vs Sperm

It's the week after Thanksgiving (for some of us) and if you're sick of leftovers, you're in luck as Elliot and Dan get together to discuss the freshest and best inter-holiday hacks. We'll cue up the "Mission: Impossible" theme for a self-destructing flash drive with a surprising sense of self-preservation, listen in on ET only to find out it's just a meteor, and look for interesting things to do with an old 3D printer. We'll do a poking around a little in the basement at Tektronix, see how easy it is to spoof biometric security, and get into a love-hate relationship with both binary G-code and bowling balls with strings attached. What do you do with a box full of 18650s? Easy -- make a huge PCB to balance them the slow way. Is your cell phone causing a population crisis? Is art real or AI? And what the heck is a cannibal CME? Tune in as we dive into all this and more. Check out the links over at Hackaday if you want to follow along, and as always, tell us what you think about this episode in the comments!

S5 Ep 245Ep 245: The Silver Swan, ET's Umbrella Antenna, Model Tanks vs Space Shuttle Tires

This week, Editor-in-Chief Elliot Williams and Managing Editor Tom Nardi link up through the magic of the Internet to go over some of their favorite stories from the last week. After revealing the bone-chilling winners of this year's Halloween contest, the discussion switches over to old-timey automatons, receiving deep space transmissions with a homebrew antenna that would make E.T. proud, and the treasures that can be found while poking around in a modern car's CAN bus. They'll also go over how NASA saved the taxpayers a bunch of money by hacking a remote controlled WWII tank, CNC controlled microscopes, and a cinema-quality camera you can probably build from what you've already got in the parts bin. Finally, they'll detail an ambitious effort to recreate an old computer's motherboard with a new feature in KiCad, and muse over all the interesting things that become possible once your test equipment can talk to your computer.

S5 Ep 244Ep 244: Fake Chips, Drinking Radium, and Spotting Slippery Neutrinos

This week, Editor-in-Chief Elliot Williams and Kristina Panos met up to discuss the best hacks of the previous week, at least in our opinions. After chasing the angry bird away from Kristina's office, we go to the news and learn that we're in the middle of a solar conjunction Essentially, the Sun has come between Earth and Mars, making communication impossible for about another week. Did you know that this happens every two years? Then it's time for a new What's That Sound, and although Kristina had an interesting albeit somewhat prompted guess, she was, of course, wrong. And then it's on to the hacks, beginning with a really cool digital pen that packs all the sensors. We learned about the world's largest musical instrument, and compared it to the Zadar Sea Organ in Croatia, which if you'll recall was once a What's That Sound. From there we take a look at fake buck converters, radioactive water as a health fad, and a garage door company that has decided to take their ball and go home. Finally we talk about how slippery neutrinos are, and discuss Tom's time at JawnCon.

S5 Ep 243Ep 243: Supercon, Super Printing, and Super Gyros

With solder fumes from Supercon badge hacking still in the air, Hackaday's Elliot Williams and Al Williams met to compare notes about the conference talks, badge hacking, and more. Tom Nardi dropped by, too. Did you miss Supercon? It isn't quite the whole experience, but most of the talks are on our YouTube channel, with more coming in the weeks ahead. Check out the live tab for most of the ones up now. You can even watch the badge hacking celebration. Al nailed What's That Sound, as did many other people, including this week's winner. [Jacx] gets a T-shirt, and you get a chance to play again next week. The hacks this week range from a pair of posts pertaining to poop -- multi-color 3D printer poop, that is. We wondered if you could print rainbow filament instead of a purge tower. The Raspberry Pi 5 draws a lot of excess power when in standby. Turns out, thanks to the Internet, the easy fix for that is already in. Other hacks range from EMI test gear to portable antennas with excursions into AI, biomedical sensors, and retrocomputing. In the Can't Miss category, we discussed Maya Posch's post, which could just as easily be titled: Everything You Ever Wanted to Know about CAT Cable (But Were Afraid to Ask). Last, but not least, you'll hear about Lewin Day's round up of exotic gyroscope technology, including some very cool laser pictures.

S5 Ep 242Ep 242: Mechanical Math, KaboomBox, and Racing the Beam

This week, Editor-in-Chief Elliot Williams and Kristina Panos met up from their separate but equally pin drop-quiet offices to discuss the best hacks of the previous week. Well, we liked these one, anyway. First up in the news, it's finally time for Supercon! So we'll see you there? If not, be sure to check out the talks as we live-stream them on our YouTube channel! Don't forget -- this is your last weekend to enter the 2023 Halloween Hackfest contest, which runs until 9 AM PDT on October 31st. Arduino are joining the fun this year and are offering some spooky treats in addition to the $150 DigiKey gift cards for the top three entrants. It's time for a new What's That Sound, and Kristina was able to stump Elliot with this one. She'll have to think of some more weirdo sounds, it seems. Then it's on to the hacks, beginning with an insanely complex mechanical central air data computer super-teardown from [Ken Shirriff]. We also learned that you can 3D-print springs and things by using a rod as your bed, and we learned whole lot about rolling your own electrolytic capacitors from someone who got to visit a factory. From there we take a look at a Commodore Datassette drive that sings barbershop, customizing printf, and a really cool dress made of Polymer-dispersed Liquid Crystal (PDLC) panels. Finally we talk about racing the beam when it comes to game graphics, and say goodbye to Kristina's series on USPS technology.

S5 Ep 241Ep 241: Circuit Bending, Resistor Filing, the Butterfly Keyboard, and the Badge Reveal

Hackaday Editors Elliot Williams and Tom Nardi meet up virtually to talk about the week's top stories and hacks, such as the fine art of resistor trimming and lessons learned from doing overseas injection molding. They'll go over circuit bending, self-driving cars, and a solar camera that started as a pandemic project and turned into an obsession. You'll also hear about Linux on the Arduino, classic ICs etched into slate, and an incredible restoration of one of the most interesting Thinkpads ever made. Stay tuned until the end to hear about a custom USB-C power supply and the long-awaited Hackaday Supercon 2023 Vectorscope badge.

S5 Ep 240Ep 240: An Amazing 3D Printer, A Look Inside Raspberry Pi 5, and Cameras, Both Film and Digital

Date notwithstanding, it's your lucky day as Elliot and Dan get together to review the best hacks of the week. For some reason, film photography was much on our writers' minds this week, as we talked about ways to digitalize an old SLR, and how potatoes can be used to develop film (is there a Monty Python joke in there?) We looked at a 3D printer design that really pulls our strings, the custom insides of the Raspberry Pi 5, and the ins and outs of both ferroresonant transformers and ham radio antennas. Learn about the SMD capacitor menagerie, build a hydrogen generator that probably won't blow up, and listen to the differences between a mess of microphones. And that's not all; the KIM-1 rides again, this time with disk drive support, Jenny tests out Serenity but with ulterior motives, and Kristina goes postal with a deep dive into ZIP codes.

S5 Ep 239Ep 239: Overclocking, Oscilloscopes, and Oh No! SMD Out of Stock!

Elliot Williams and Al Williams got together again to discuss the best of Hackaday for a week, and you're invited. This week, the guys were into the Raspberry Pi 5, CNC soldering, signal processing, and plasma cutting. There are dangerous power supplies and a custom 11-bit CPU. Of course, there are a few Halloween projects that would fit in perfectly with the upcoming Halloween contest (the deadline is the end of this month; you still have time). OpenSCAD is about to get a lot faster, and a $20 oscilloscope might not be a toy after all. They wrap up by talking about Tom Nardi's latest hardware conversion of DIP parts to SMD and how TVs were made behind the Iron Curtain. Did you miss a story?

S5 Ep 238Ep 238: Vibrating Bowl Feeders, Open Sourcery, Learning to Love Layer Lines

Elliot Williams and Tom Nardi start this week's episode off with some deep space news, as NASA's OSIRIS-REx returns home with a sample it snapped up from asteroid Bennu back in 2020. From there, discussion moves on to magical part sorting, open source (eventually...) plastic recycling, and the preposterously complex method newer Apple laptops use to determine if their lid is closed. They'll also talk about the changing perceptions of 3D printed parts, a new battery tech that probably won't change the world, and a clock that can make it seem like your nights are getting longer and longer. Stick around until the end to hear about the glory days of children's architecture books, and the origins of the humble microwave oven.

S5 Ep 237Ep 237: Dancing Raisins, Coding on Apples, and a Salad Spinner Mouse

This week, Editor-in-Chief Elliot Williams and Kristina Panos gathered over the Internet and a couple cups of coffee to bring you the best hacks of the previous week. Well, the ones we liked best, anyhow. First up in the news, we've got a brand-spankin' new Halloween Hackfest contest running now until 9AM PDT on October 31st! Arduino are joining the fun this year and are offering some spooky treats in addition to the $150 DigiKey gift cards for the top three entrants. It's a What's That Sound Results Show this week, and although Kristina actually got into the neighborhood of this one, she alas did not figure out that it was an MRI machine (even though she spent a week in an MRI one day). Then it's on to the hacks, which had a bit of a gastronomical bent this week. We wondered why normies don't want to code on their Macs, both now and historically. We also examined the majesty of dancing raisins, and appreciated the intuitiveness of a salad spinner-based game controller. From there we take a look at nitinol and its fun properties, admire some large, beautiful Nixie tubes, and contemplate a paper punching machine that spits out nonsensical binary. Finally we talk about rocker bogie suspensions and the ponder the death of cursive.

S5 Ep 236Ep 236: The Car Episode, Building Leonardo's Water Mill, Reviving Radio Shack

Elliot and Dan got together this time around to recap the week in hacks, and it looks like the Hackaday writing crew very much had cars on their minds. We both took the bait, with tales of privacy-violating cars and taillights that can both cripple a pickup and financially cripple its owner. We went medieval -- OK, more like renaissance -- on a sawmill, pulled a popular YouTuber out of the toilet, and pondered what an animal-free circus would be like. Is RadioShack coming back? Can an ESP32 board get much smaller than this? And where are all the retro(computer)virus writers? We delve into these questions and more, while still saving a little time to wax on about personal projects. And although the show is peppered with GSM interference (Elliot says sorry!) it's not actually a clue for the What's That Sound.

S5 Ep 235Ep 235: Licorice for Lasers, Manual Motors, and Reading Resistors

Name one other podcast where you can hear about heavy 3D-printed drones, DIY semiconductors, and using licorice to block laser beams. Throw in homebrew relays, a better mouse trap, and logic analyzers, and you'll certainly be talking about Elliot Williams and Al Williams on Hackaday Podcast 235. There's also contest news, thermoforming, and something that looks a little like 3D-printed Velcro. Elliot and Al also have their semi-annual argument about Vi vs. Emacs. Spoiler alert: they decided they both suck. Missed any of their picks? Check out the links on Hackaday, and as always, tell us what you think about this episode in the comments!

S5 Ep 234Ep 234: Machines on Fire, Old Kinect New Kinect, and Birth of the Breadboard

It might sound like a joke, but this week, Elliot Williams and Tom Nardi start things off by asking how you keep a Polish train from running. Like always, the answer appears to be a properly modulated radio signal. After a fiery tale about Elliot's burned beans, the discussion moves over to the adventure that is home CNC ownership, the final chapter in the saga of the Arecibo Telescope, and the unexpected longevity of Microsoft's Kinect. Then it's on to the proper way to cook a PCB, FFmpeg in the browser, and a wooden cyberdeck that's worth carrying around. Finally, they'll go over the next generation of diode laser engravers, and take a look back at the origins of the lowly breadboard.

S5 Ep 233Ep 233: Chandrayaan on the Moon, Cyberdecks, Hackerspaces Born at a German Computer Camp

This week, Editor-in-Chief Elliot Williams and Kristina Panos experimented with the old adage that brevity is the soul of wit. That's right; this week, they're all Quick Hacks, and that's to make room for a special series of interviews that Elliot recorded at CCCamp with the pillars of US hackerspace creation. This one's really special, do have a listen. We still made room for the news this week: India launched Chandrayaan-3, which combines an orbiter, lander, and rover all in one. Then it's on to the What's That Sound results show, and while Kristina did not get it right, she did correctly identify it as being used in Whitney Houston's "I Wanna Dance With Somebody", as did one of the guessers who identified it as the cowbell sound from a Roland 808. Then it's on to the (quick) hacks, where we alternated for once just to keep things interesting. This week, Elliot is into 3D printing a clay extruder and then printing pottery with that, z-direction conductive tape, and the humble dipole antenna. Kristina is more into cyberdecks for the young and old, a reusable plant monitor, and 3D printing some cool coasters.

S5 Ep 231Ep 231: Harnessing Sparks, Hacking Food, and Leaving Breadcrumbs

Editor-in-Chief Elliot Williams and Al Williams don't always agree on the best text editor to use, but they do -- usually -- agree on what makes a great hack. This week, they found plenty of Hackaday posts to discuss, ranging from exotic eavesdropping on keyboards, oscilloscopes, and several posts of interest to anyone who wants to build good-looking prototypes. If you are like mechanics, you'll hear about an escapement-like mechanism and a Hobson's coupler. If you crave more traditional hacks, you can learn more about maximizing battery life and etching PCBs. In addition to a flurry of hacks, Elliot and Al also share their picks for the best original posts from Hackaday's staff. This week, we find out how Arya Voronova documents projects and hear what Tom Nardi thinks of his Beepy -- a ready-made display and Blackberry keyboard waiting for a Raspberry Pi.

S5 Ep 230Ep 230: Space Science, Superconductors, Supercaps, and Central Air

This week, Editor-in-Chief Elliot Williams and Managing Editor Tom Nardi start things off by tackling a pair of science stories, one that may or may not change the world, and the other that hopes to help us understand the very fabric of the universe. Afterwards they get to the important stuff: the evolution of Game Boy Camera hacking, the finer points of 3D print orientation, and mixing up electrically conductive concrete at home. From there the conversation shifts to a couple of 486 Turbo buttons, a quick yoke recipe, and a very handsome open source vacuum pickup tool. Stick around until the end to hear about the folly of humanoid robots, and the latest operating system to get the Jenny List treatment.

S5 Ep 229Ep 229: DIY VR, Gutting Voice Assistants, and ChatGPT Failing Its Summer Internship

This week, Editor-in-Chief Elliot Williams and Kristina Panos braved the slight cold and the high heat respectively to bring you the best hacks of the previous seven days. In the news this week: you've got a second and final chance to get your Supercon talk proposals in! So get on that, because we need YOU to help make Supercon awesome. We can chalk up a win for Kristina on What's That Sound this week (finally!). Will you get it right? Will you get it exactly right? Time and Elliot's fancy dice will tell. Then it's on to the hacks, where we check out a cool RFID emulator e-paper badge, discuss whether a certain type of record player is better off as a cyberdeck, and look through the eye of a Gameboy-style camera for the Playdate console. From there we take a look at gutting and rooting voice assistants, a solenoid keyboard, and a beautifully rebuilt VR headset that now does AR as well. Finally we talk autonomous solar boats, lambast ChatGPT as the worst summer intern ever, and ponder what makes a thing count as Linux or not.

S5 Ep 228Ep 228: Bats, Eggs, Lasers, Duck Tape, and Assembly Language

Summer's in full swing, and this week both Elliot and Dan had to sweat things out to get the podcast recorded. But the hacks were cool -- see what I did there? -- and provided much-needed relief. Join us as we listen in on the world of bats, look at a laser fit for a hackerspace, and learn how to make an array of magnets greater than -- or less than -- the sum of its parts. There'll be flying eggs, keyboards connected to cell phones, and everything good about 80s and 90s cable TV, as well as some of the bad stuff. And you won't want to miss Elliot putting Dan to shame with the super-size Quick Hacks, either, nor should you skip the Can't Miss sweep with a pair of great articles by Al Williams.

S5 Ep 227Ep 227: Open Source Software, Decoupling Caps, DIY VR

Elliot Williams and Tom Nardi start this week's episode by addressing the ongoing Red Hat drama and the trend towards "renting" software. The discussion then shifts to homebrew VR gear, a particularly impressive solar-powered speaker, and some promising developments in the world of low-cost thermal cameras. Stay tuned to hear about color-changing breadboards, an unofficial logo for repairable hardware, and five lines of Bash that aim to unseat the entrenched power of Slack. Finally, we'll take the first steps in an epic deep-dive into the world of DisplayPort, and take a journey of the imagination aboard an experimental nuclear ocean liner.
