Elliot and Al got together to discuss this week’s projects, and you’re invited! You’ll hear news about replaceable batteries in the EU, along with some news about the Hackaday Op Amp Challenge winners and the start of a new contest. This week’s choice hacks ranged from a Star Wars-style volumetric display, navigation using cosmic rays, measuring car speed with microphones, and a crazy 3D printing technique that will blow you away.

There’s plenty more where that came from. Ever tried to land a model rocket vertically? How about building a punched card reader? The can’t miss articles this week cover a thermal camera review and the unintended consequences if AM radio bites the dust.

Elliot’s back from vacation, and Dan stepped into the virtual podcast studio with him to uncover all the hacks he missed while hiking in Italy. There was a lot to miss, what with a smart meter getting snuffed by a Flipper Zero — or was it? How about a half-gigapixel camera built out of an old scanner, or a sonar-aimed turret gun? We also looked at a couple of projects that did things the hard way, like a TV test pattern generator that was clearly a labor of love, and an all-transistor HP frequency counter. More plastic welding? Hey, a fix is a fix! Plus, we’ll dive into why all those Alexas are just gathering dust, and look at the really, REALLY hard problems involved in restoring shredded documents.

Editors Elliot Williams and Tom Nardi are back in the (virtual) podcast studio to talk the latest phase of the 2023 Hackaday Prize, the past, present, and future of single-board computers, and a modern reincarnation of the Blackberry designed by hardware hackers. They’ll also cover the current state of toothbrush NFC hacking, the possibilities of electric farm equipment, and a privately funded satellite designed to sniff out methane. Stick around till the end to find out if there really is such a thing as having too many tools.

You can join Elliot and Al as they get together to talk about their favorite hacks of the week. There’s news about current contests, fake alien messages, flexible breadboards, hoverboards, low-tech home automation, and even radioactive batteries that could be a device’s best friend.

We have a winner in the What’s that Sound competition last week, which was, apparently, a tough one. You’ll also hear about IC fabrication, FPGAs, and core memory. Lots to talk about, including core memory, hoverboards, and vacuum tubes.

Elliot and Dan teamed up for the podcast this week, bringing you the week’s sweetest hacks. And news too, as the ESA performed a little percussive maintenance on a Jupiter-bound space probe, and we learned about how to get an Orwellian free TV that exacts quite a price. We talked about Bitcoin mining two ways, including a way to put all that waste heat to good use — just don’t expect it to make good financial sense. Why would you stuff zip ties into a hot glue gun? It might just help with plastic repair. Lugging a tube transmitter up a mountain doesn’t sound like a good idea, but with the right design, it’s a lot of fun — and maybe you’ll be better able to tap into Schumann resonances while you’re up there.
