Ep 161: Laser Lithography, Centurion Hard Drive, and Mad BGA Soldering
Join Hackaday Editor-in-Chief Elliot Williams and Staff Writer Dan Maloney for an audio tour of the week's top stories and best hacks. We'll look at squeezing the most out of a coin cell, taking the first steps towards DIY MEMS fabrication, and seeing if there's any chance that an 80's-vintage minicomputer might ride again. How small is too small when it comes to chip packages? We'll find out, and discover the new spectator sport of microsoldering while we're at it. Find out what's involved in getting a real dead-tree book published, and watch a hacker take revenge on a proprietary memory format -- and a continuous glucose monitor, too. Head over to Hackaday for links in the show notes!

Ep 160: Pedal Power, OpenSCAD in the Browser, Tasmanian Tigers, and the Coolest Knob
Join Hackaday Editor-in-Chief Elliot Williams and Managing Editor Tom Nardi as they tackle all the hacks that were fit to print this last week. Things start off with some troubling news from Shenzhen (spoilers: those parts you ordered are going to be late), and lead into a What's That Sound challenge that's sure to split the community right down the center. From there we'll talk about human powered machines, bringing OpenSCAD to as many devices as humanly possible, and the finer points of installing your own hardware into a Pelican case. There's a quick detour to muse on laser-powered interstellar probes, a Pi-calculating Arduino, and a surprisingly relevant advertisement from Sony Pictures. Finally, stay tuned to hear the latest developments in de-extinction technology, and a seriously deep dive into the lowly nail.

Ep 159: Zombie Killer or Rug Maker, 3D Printed Rims, 1950s Drum Machines, and Batteries on Wheels
Join Hackaday Editor-in-Chief Elliot Williams and Managing Editor Tom Nardi as they look back on the best hacks and stories of the previous week. There's plenty in the news to talk about, though between faulty altimeters and the ongoing conflict in Ukraine, it isn't exactly of the positive variety. But things brighten up quickly as discussion moves on to 3D printed car wheels, a fantastically complex drum machine from 1958, a unique take on the seven-segment flip display, and a meticulously designed (and documented) coffee machine upgrade. Somewhere in there a guy also recreates a rare German anti-air rocket launcher from WWII, but it's all in the name of history. We'll also tackle two very different forms of electric propulsion, from the massive wheeled batteries popping up in garages and driveways all over the world to high-efficiency thrusters for deep space missions.

Ep 158: Phased Array Physics, CRTs Two Ways, A Micro Microcontroller, and a Surgically Implanted Red Herring
Join Editor-in-Chief Elliot Williams and Staff Writer Dan Maloney as they take a look at the week's top stories, taken straight off the pages of Hackaday. What happens when you stuff modern parts into a 90's novelty PC case? Nothing good, but everything awesome! Is there any way to prevent PCB soil moisture sensors from being destroyed by, you know, soil moisture? How small is too small for a microcontroller, and who needs documentation anyway? We also cast a jaundiced eye -- err, ear -- at an electronic cheating scandal, and if you've ever wondered how phased arrays and beam steering work, gazing into a pan of water might just answer your questions. We also share all our soldering war stories, and hey -- what's with all these CRT projects anyway? Links in the show notes!

Ep 157: Airtag Security, Warped 3D Printing, Suturing Grapes with a DIY Robot Arm, and the Wizard's Calculator
This week Hackaday Editor-in-Chief Elliot Williams and Managing Editor Tom Nardi look at the week's most interesting stories and projects, starting with the dystopian news that several people have had their bionic eye implants turn off without warning. We then pivot into an only slightly less depressing discussion about the poor security of Apple's AirTags network and how it can be used to track individuals without their knowledge. But it's not all doom and gloom. We'll look at new projects designed to push the envelope of desktop 3D printing, and marvel at a DIY robotic arm build so accurate that it can put stitches in the skin of a grape. You'll also hear about the surprisingly low cost of homebrew hydrophones, the uncomfortable chemistry behind wintergreen, and an early portable computer that looks like it came from Hogwarts School of Witchcraft and Wizardry.

Ep 156: 3D-Printing Rainbows, Split-Flap Clocks, Swapping EV Car Batteries, and Floppy Time
This week, Hackaday Editor-in-Chief Elliot Williams and Assignments Editor Kristina Panos fawn over a beautiful Italian split-flap clock that doesn't come cheap, and another clock made of floppies that could be re-created for next to nothing. We'll also sing the praises of solderless circuitry for prototyping and marvel over a filament dry box with enough sensors to control an entire house. The finer points of the ooh, sparkly-ness of diffraction gratings will be discussed, and by the end of the show, you'll know what we each like in a microscope. Check out the show notes for links!

Ep 155: Dual Integrating Spheres, More Magnetic Switches, PlottyBot, Red Hair in Your Wafers
This week Hackaday Editor-in-Chief Elliot Williams and Managing Editor Tom Nardi take a close look at two pairs of projects that demonstrate the wildly different approaches that hackers can take while still arriving at the same conclusion. We'll also examine the brilliant mechanism that the James Webb Space Telescope uses to adjust its mirrors, and marvel over a particularly well-developed bot that can do your handwriting for you. The finer points of living off home-grown algae will be discussed, and by the end of the show, you'll learn the one weird trick to stopping chip fabs in their tracks. Check out all the links, and Tom's Algae, on Hackaday!

Ep 154: A Good Enough CNC, Stepper Motors Unrolled, Smart Two-Wire LEDs, a Volcano Heard Around the World
Join Hackaday Editor-in-Chief Elliot Williams and Staff Writer Dan Maloney for this week's podcast as we talk about Elliot's "defection" to another podcast, the pros and cons of CNC builds, and making Nixie clocks better with more clicking. We'll explore how citizen scientists are keeping a finger on the pulse of planet Earth, watch a 2D stepper go through its paces, and figure out how a minimalist addressable LED strip works. From solving a Rubik's cube to answering the age-old question, "Does a watched pot boil?" -- spoiler alert: if it's well designed, yes -- this episode has something for everyone.
