Ep 315: Conductive String Theory, Decloudified Music Players, and Wild Printing Tech
This week, Hackaday's Elliot Williams and Kristina Panos met up across the (stupid, lousy) time zones to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous week. Again, no news is good news. On What's That Sound, Kristina didn't get close at all, but at least had a guess this time. If you think you can identify the sound amid all the talking, you could win a Hackaday Podcast t-shirt! After that, it's on to the hacks and such, beginning with a Dr. Jekyll and Mr. Hyde situation when it comes to a pair of formerly-cloud music players. We take a look at a crazy keyboard hack, some even crazier conductive string, and a perfectly cromulent list of 70 DIY synths on one wild webpage. Finally, we rethink body art with LEDs, and take a look at a couple of printing techniques that are a hundred years or so apart in their invention.

Ep 314: It's Pi, but Also PCBs in Living Color and Ultrasonic Everything
It might not be Pi Day anymore, but Elliot and Dan got together for the approximately 100*Pi-th episode of the Podcast to run through the week's coolest hacks. Ultrasound seemed to be one of the themes, with a deep dive into finding bugs with sonar as well as using sound to cut the cheese -- and cakes and pies, too. The aesthetics of PCBs were much on our minds, too, from full-color graphics on demand to glow-in-the-dark silkscreens. Is automation really needed to embed fiber optics in concrete? Absolutely! How do you put plasma in a bottle? Apparently, with kombucha, Nichrome, and silicone. If you need to manage your M:TG cards, scribble on the walls, or build a mechanical chase light, we've got the details. And what exactly is a supercomputer? We can't define it, but we know one when we see it. Check out all the links over at Hackday!

Ep 313: Capacitor Plague, Wireless Power, and Tiny Everything
We're firmly in Europe this week on the Hackaday podcast, as Elliot Williams and Jenny List are freshly returned from Berlin and Hackaday Europe. A few days of mingling with the Hackaday community, going through mild panic over badges and SAOs, and enjoying the unique atmosphere of that city. After discussing the weekend's festivities we dive right into the hacks, touching on the coolest of thermal cameras, wildly inefficient but very entertaining wireless power transfer, and a restrospective on the capacitor plague from the early 2000s. Was it industrial espionage gone wrong, or something else? We also take a moment to consider spring PCB cnnectors, as used by both one of the Hackaday Europe SAOs, and a rather neat PCB resistance decade box, before looking at a tryly astounding PCB blinky that sets a new miniaturisation standard. In our quick roundup the standouts are a 1970s British kit synthesiser and an emulated 6502 system written in shell script, and in the can't-miss section we look at a new contender fro the smallest microcontroller, and the posibility that a century of waste coal ash may conceal a fortune in rare earth elements.

Ep 312: Heart Attacks, the Speed of Light, and Self-balancing
Elliot does the podcast on the road to Supercon Europe, and Al is in the mood for math and nostalgia this week. Listen in and find out what they were reading on Hackaday this week. The guys talked about the ESP-32 non-backdoor and battery fires. Then it was on to the hacks. Self-balancing robots and satellite imaging were the appetizers, but soon they moved on to Kinect cameras in the modern day. Think you can't travel at the speed of light? Turns out that maybe you already are. Did you know there was a chatbot in 1957? Well, sort of. For the can't miss stories: watches monitor your heart and what does the number e really mean?

Ep 311: AirTag Hack, GPS Rollover, and a Flat-Pack Toaster
This week, Elliot Williams and Tom Nardi start off the episode by announcing Arduino co-founder David Cuartielles will be taking the stage as the keynote speaker at Hackaday Europe. In his talk, we'll hear about a vision of the future where consumer electronics can be tossed in the garden and turned into compost instead of sitting in a landfill for the next 1,000 years or so. You'll also hear about a particularly clever manipulation of Apple's AirTag infrastructure, how a classic kid's toy was turned into a unique display with the help of computer vision, and the workarounds required to keep older Global Positioning System (GPS) hardware up and running. They'll also cover DIY toasters, extracting your data from a smart ring before the manufacturer can sell it, a LEGO interferometer, and a new feature added to the Bus Pirate 5's already impressive list of capabilities. Capping off the episode there's a discussion about the surprising (or depending on how you think about it, unsurprising) amount of hardware that was on display at FOSDEM this year, and the history of one of man's most infernal creations, the shopping cart wheel lock.
