Hackaday Podcast Episode 270: A Cluster Of Microcontrollers, A Rocket Engine From Scratch, And A Look Inside Voyager

Join Hackaday Editors Elliot Williams and Tom Nardi as they get excited over the pocket-sized possibilities of the recently announced 2024 Business Card Challenge, and once again discuss their picks for the most interesting stories and hacks from the last week. There’s cheap microcontrollers in highly parallel applications, a library that can easily unlock the world of Bluetooth input devices in your next project, some gorgeous custom flight simulator buttons that would class up any front panel, and an incredible behind the scenes look at how a New Space company designs a rocket engine from the ground up.

Stick around to hear about the latest 3D printed gadget that all the cool kids are fidgeting around with, a brain-computer interface development board for the Arduino, and a WWII-era lesson on how NOT to use hand tools. Finally, learn how veteran Hackaday writer Dan Maloney might have inadvertently kicked off a community effort to digitize rare documentation for NASA’s Voyager spacecraft.

FLOSS Weekly Episode 782: Nitric — In Search Of The Right Knob

This week Jonathan Bennett and David Ruggles chat with Rak Siva and Steve Demchuck to talk about Nitric! That’s the Infrastructure from Code framework that makes it easy to use a cloud back-end in your code, using any of multiple providers, in multiple programming languages.

The group chatted about the role and form of good documentation, as well as whether a Contributor License Agreement is ever appropriate, and what a good CLA would actually look like. Don’t miss it!

Hackaday Podcast Episode 269: 3D Printed Flexure Whegs, El Cheapo Bullet Time, And A DIY Cell Phone Sniffer

This week, it was Kristina’s turn in the hot seat with Editor-in-Chief Elliot Williams. First up in the news — the results are in for the 2024 Home Sweet Home Automation contest! First and second place went to some really gnarly, well-documented hacks, and third went to the cutest pill-dispensing robot you’ll probably see before you hit the retirement home. Which was your favorite? Let us know in the comments.

Then it’s on to What’s That Sound. Kristina failed once again, but you will probably fare differently. Can you get it? Can you figure it out? Can you guess what’s making that sound? If you can, and your number comes up, you get a special Hackaday Podcast t-shirt.

Then it’s on to the hacks, beginning with a DIY cell phone sniffer and a pen that changed the world. Then we talk bullet time on a budget, the beautiful marriage of 3D printing and LEGO, and, oh yes, flexure whegs. Finally, we get the lowdown on extender probes, and posit why it’s hard to set up time zones on the Moon, relatively speaking.

FLOSS Weekly Episode 781: Resistant To The Wrath Of God

This week Jonathan Bennett and Doc Searls sit down with Mathias Buus Madsen and Paolo Ardoino of Holepunch, to talk about the Pear Runtime and the Keet serverless peer-to-peer platform. What happens when you take the technology built for BitTorrent, and apply it to a messaging app? What else does that allow you to do? And what’s the secret to keeping the service running even after the servers go down?

Hackaday Podcast Episode 268: RF Burns, Wireless Charging Sucks, And Barnacles Grow On Flaperons

Not necessarily the easy way to program an EPROM

Elliot and Dan got together to enshrine the week’s hacks in podcast form, and to commiserate about their respective moms, each of whom recently fell victim to phishing attacks. It’s not easy being ad hoc tech support sometimes, and as Elliot says, when someone is on the phone telling you that you’ve been hacked, he’s the hacker. Moving on to the hacks, we took a look at a hacking roadmap for a cheap ham radio, felt the burn of AM broadcasts, and learned how to program old-school EPROMs on the cheap.

We talked about why having a smart TV in your house might not be so smart, especially for Windows users, and were properly shocked by just how bad wireless charging really is. Also, cheap wind turbines turn out to be terrible, barnacles might give a clue to the whereabouts of MH370, and infosec can really make use of cheap microcontrollers.

FLOSS Weekly Episode 780: Zoneminder — Better Call Randal

This week Jonathan Bennett and Aaron Newcomb chat with Isaac Connor about Zoneminder! That’s the project that’s working to store and deliver all the bits from security cameras — but the CCTV world has changed a lot since Zoneminder first started, over 20 years ago. The project is working hard to keep up, with machine learning object detection, WebRTC, and more. Isaac talks a bit about developer burnout, and a case or two over the years where an aggressive contributor seems suspicious in retrospect. And when is the next stable version of Zoneminder coming out, anyway?

Hackaday Podcast Episode 267: Metal Casting, Plasma Cutting, And A Spicy 555

What were some of the best posts on Hackaday last week? Elliot Williams and Al Williams decided there were too many to choose from, but they did take a sampling of the ones that caught their attention. This week’s picks were an eclectic mix of everything from metal casting and plasma cutters to radio astronomy and space telescope budgets. In between? Some basic circuit design, 3D printing, games, dogs, and software tools. Sound confusing? It won’t be, after you listen to this week’s podcast.
