Hackaday Podcast Episode 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.

Hackaday Podcast Episode 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).

Hackaday Podcast Episode 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.

Hackaday Podcast Episode 259: Twin-T, Three-D, And Driving To A Tee

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?

Hackaday Podcast Episode 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.

Hackaday Podcast Episode 256: 0, 256, 400, 0x100, 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.

Hackaday Podcast Episode 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.
