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.

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, 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.
