Hackaday Podcast Episode 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 and wind power generation 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.

Hackaday Podcast Episode 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.

FLOSS Weekly Episode 784: I’ll Buy You A Poutine

This week Jonathan Bennett and Dan Lynch talk with François Proulx about Poutine, the Open Source security scanner for build pipeline vulnerabilities. This class of vulnerability isn’t as well known as it should be, and threatens to steal secrets, or even allow for supply chain attacks in FLOSS software.

Poutine does a scan over an organization or individual repository, looking specifically for pipeline issues. It runs on both GitHub and GitLab, with more to come!

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.
