Ep 314: It's Pi, but Also PCBs in Living Color and Ultrasonic Everything

Hackaday Editors Mike Szczys and Elliot Williams are back after last week's holiday break to track down all of the hacks you missed. There are some doozies; a selfie-drone controlled by your body position, a Theremin that sings better than you can, how about a BGA hand-soldering project whose creator can't even believe he pulled it off. Kristina wrote a spectacular article on the life and career of Mary Sherman Morgan, and Tom tears down a payment terminal he picked up in an abandoned Toys R Us, plus much more!

Hackaday Editors Mike Szczys and Elliot Williams dish their favorite hacks from the past week. Seems like everyone is trying to mill their own Mac Pro grille and we love seeing how they go about it. Elliot is gaga over a quintet of power latching circuits, Mike goes crazy for a dough sheeter project, and we dig through the news behind methane on Mars, the Raspberry Pi 4 release, and spoofing Presidential text alerts with SDR. If you like mini-keyboards you need to see the Fauxberry, Artificial Intelligence became an art critic this week, and poorly-lit rooms have been solved with a massive mirror system.

Hackaday Editors Elliot Williams and Mike Szczys wade through the fun hacks of the week. Looks like Google got caught ripping off song lyrics (how they got caught is the hack) and electric cars are getting artificially noisier. We look at 3D Printing directly from used plastic, and building a loom with many hundreds of 3D printed parts. The Sound Blaster 1.0 lives again thanks to some (well-explained) reverse engineered circuitry. Your smartphone is about to get a lot more buttons that work without any extra electronics, and we'll finish things up with brass etching and downloadable nuclear reactor plans.

Mike Szczys and Elliot Williams talk news and great hacks from the past seven days. Sad word this week as Maker Media, the company behind Make Magazine and Maker Faire, have closed their doors. There seems to be a lot of news about broken hardware to discuss with ADS-B problems grounding hundreds of flights in the US, Hackaday itself had a site outage, Raspberry Pi 3 B+ can be bricked with a really easy mistake, and Lewin wrote a great overview of the Takata airbag debacle. Don't worry there are still plenty of hacks as we look at old computers that sing, microcontrollers that chiptune, beat boxes that are actually boxes, and some very neat cartridge hacks for NES and Arduboy.

Elliot Williams and Mike Szczys dig through the most interesting hacks from the past week. On this episode we take a look at a portable power bank build that defies belief. We discuss an all-in-one SDR portable, messing with restaurant pagers, and the software that's common to both of these pursuits. There's a hopping robot that is one heck of a PID challenge, and another robot that does nothing but stare you down. We bring it on home with great articles on pianos with floppy disks, and that satellite cluster you should be watching for in the night sky. Show Notes: https://hackaday.com/?p=361762

Mike Szcycz is on a well-deserved vacation this week, so staff writer Dan Maloney joins managing editor Elliot Williams for a look at all the great hacks of the week. On this episode we're talking about licensing fees for MIDI 2.0, a two-way fail while snooping on employees, and the potential for diagnosing Alzheimer's with virtual reality. We also dive into the well-engineered innards of a robotic cheetah, a personal assistant safe enough for kids to use, and how listening to your monitor reveals more about you than you'd think. You don't want to miss a space nerd's quest for fire or a hacker's guide to solder and soldering. And you've got to catch the story of a hapless hacker's contact high from a vintage synthesizer. It's quite a trip. Show Notes: https://hackaday.com/?p=360003

Join editors Elliot Williams and Mike Szczys as they unpack all the great hacks we've seen this week. On this episode we're talking about laser Internet delivered from space, unwrapping the complexity of Charlieplexed circuits, and decapping ICs both to learn more about them and to do it safely at home. We have some fun with backyard siege weapons (for learning about physics, we swear!), gambling on FPGAs, and a line-scanning camera that's making selfies fun again. And nobody thought manufacturing electroluminescent displays was easy, but who knew it was this hard? Show notes: https://hackaday.com/?p=360002

Join Mike Szczys and Elliot Williams as they riff on the coolest hacks from the past week. Clocks and 3D printing seem to keep coming up this week as we look at using an FPGA plus GPS receiver for better accuracy than we're used to, and we haggle over what to call the robot arms that nudge the hands on a shelf-clock. There's a wicked 3D-printed planetary gear design, and brackets that turn flat cardboard into boxes (more useful than you might think). We close out with great reads on the Supermicro fallout of the last 7 months, and a pretty big oops moment as a hacker knocks out keyfobs for an entire neighborhood.
