Hackaday Podcast Episode 345: A Stunning Lightsaber, Two Extreme Cameras, And Wrangling Roombas

It’s a wet November evening across Western Europe, the steel-grey clouds have obscured a rare low-latitude aurora this week, and Elliot Williams is joined by Jenny List for this week’s podcast. And we’ve got a fine selection for your listening pleasure!

The 2025 Component Abuse Challenge has come to an end, so this week you’ll be hearing about a few of the entries. We’ve received an impressive number, and as always we’re bowled over by the ingenuity of Hackaday readers in pushing parts beyond their limits.

In the news is the potential discovery of a lost UNIX version in a dusty store room at the University of Utah, Version 4 of the OS, which appeared in 1973. Check out your own stores, for hidden nuggets of gold. In the hacks, we have two cameras at the opposite end of the resolution spectrum, but sharing some impressive reverse engineering. Mouse cameras and scanner cameras were both a thing a couple of decades ago, and it’s great to see people still pushing the boundaries. Then we look at the challenge of encoding Chinese text as Morse code, an online-upgraded multimeter, the art of making lenses for an LED lighting effect, and what must be the best recreation of a Star Wars light sabre we have ever seen. In quick hacks we have a bevvy of Component Abuse Challenge projects, a Minecraft server on a smart light bulb, and a long term test of smartphone battery charging techniques.

We round off with a couple of our long-form pieces, first the uncertainties about iRobot’s future and what it might mean for their ecosystem — think: cheap hackable robotics platform! — and then a look at FreeBSD as an alternative upgrade path for Windows users. It’s a path not without challenges, but the venerable OS still has plenty to give.

As always, you can listen using the links below, and we’ve laidout links to all the articles under discussion at the bottom of the page.

FLOSS Weekly Episode 854: The Big Daddy Core

This week Jonathan and Ben chat with Jason Shepherd about Ocre and Atym.io! That’s the lightweight WebAssembly VM that lets you run the same containers on Linux and a host of embedded platforms, on top of the Zephyr embedded OS. What was the spark that led to this project’s creation, what does Atym.io bring to the equation, and what are people actually doing with it? Watch to find out!

Hackaday Podcast Episode 344: Board With Lasers, Op-Amp Torture, And Farewell Supercon 9

Hackaday Editors Tom Nardi and Al Williams spent the weekend at Supercon and had to catch up on all the great hacks. Listen in as they talk about their favorites. Plus, stick around to the end to hear about some of the highlights from their time in Pasadena.

If you’re still thinking about entering the Component Abuse Contest, you’re just about out of time. Need some inspiration? Tom and Al talk about a few choice entries, and discuss how pushing parts out of their comfort zone can come in handy. Do you make your own PCBs? With vias? If you have a good enough laser, you could. Or maybe you’d rather have a $10 Linux server? Just manage your expectations. The guys both admit they aren’t mechanical geniuses and, unlike [4St4r], aren’t very good at guessing sounds either. They round up with some 3D printing projects and a collection of quick hacks.

FLOSS Weekly Episode 853: Hardware Addiction; Don’t Send Help

This week Jonathan and Rob chat with Cody Zuschlag about the Xen project! It’s the hypervisor that runs almost everywhere. Why is it showing up in IoT devices and automotive? And what’s coming next for the project? Watch to find out!

Hackaday Podcast Episode 343: Double Component Abuse, A Tinkercad Twofer, And A Pair Of Rants

This week, Hackaday’s Elliot Williams and Kristina Panos met up across the universe to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous seven days or so.

In Hackaday news, OMG Supercon is almost here! And we just revealed the badge! In other news, we’ve still got a contest running. Read all about the 2025 Component Abuse Challenge, sponsored by DigiKey, and check out the contest page for all the details.

On What’s That Sound, Kristina failed spectacularly. Will you fare better and perhaps win a Hackaday Podcast t-shirt? Mayhap you will.

After that, it’s on to the hacks and such, beginning with a really cool entry into the Component Abuse Challenge wherein a simple transmission line is used to multiply a voltage. We watch as a POV globe takes to the skies, once it has enough motors.

Then we discuss several awesome hacks such as an incredible desk that simulates beehive activity, a really great handheld PC build, and a Tinkercad twofer. Finally, we discuss the future of removable batteries, and the history of movable type.

Hackaday Podcast Episode 342: Poopless Prints, Radio In Your Fillings, And One Hyperspectral Pixel At A Time

It was Elliot and Dan on the podcast today, taking a look at the best the week had to offer in terms of your hacks. We started with surprising news about the rapidly approaching Supercon keynote; no spoilers, but Star Trek fans such as we who don’t have tickets will be greatly disappointed.

Elliot waxed on about taking the poop out of your prints (not pants), Dan got into a camera that adds a dimension to its images, and we both delighted in the inner workings of an air-powered squishy robot.

Questions? We’ve got plenty. Is it possible to take an X-ray without an X-ray tube? Or X-rays, for that matter? Did Lucille Ball crack a spy ring with her fillings? Is Algol set to take over the world? What’s inside a germanium transistor? How does a flipping fish say Happy Birthday? And how far down the Meshtastic rabbit hole did our own Tom Nardi fall? Tune in to find out the answers.
