Ep 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.

Episode 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.

Ep 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!

Ep 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.

Ep 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.

Ep 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.

Ep 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.

Ep 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.

Ep 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.

Ep 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.
