Hackaday Podcast 118: Apple AirTag Hacked, Infill Without Perimeters, Hair-Pulling Robots, And Unpacking The 555

Elliot’s keeb: ortho, offset, thumby.

Hackaday editors Elliot Williams and Mike Szczys gather to ooh and aah over a week of interesting hacks. This week we’re delighted to welcome special guest Kristina Panos to talk about the Inputs of Interest series she has been working on over the last couple of years. In the news is the effort to pwn the new Apple AirTags, with much success over the past week. We look at turning a screenless Wacom tablet into something more using a donor iPad, stare right into the heart of a dozen 555 die shots, and watch what happens when you only 3D print the infill and leave the perimeters out.

Hackaday Podcast 116: Three DIY Lab Instruments, Two Tickers, And A MicroCar

Hackaday editors Elliot Williams and Mike Szczys select our favorite hardware hacks of the past week. This episode is packed with DIY lab instruments, including a laser microscope, a Raspberry Pi spectrometer, and a stepper motor tester that can tell you what’s going on all the way down to the microsteps. We wax poetic about what modular hardware really means, fall in love with a couple of stock-ticker robots, and chat with special guest Tom Nardi about his experience at the VCF Swap Meet.

Split Keyboard Finder Stacks Them Up For Your Approval

Tired of a boring, single piece keyboard? Thinking about a change but don’t know what all your options are? Well prospective-keyboard-shopper, today is your lucky day. We at the Hackaday are here to facilitate the habit with two excellent resources for the eager keyboard shopper; [pvinis]’s awesome-split-keyboards and [jhelvy]’s splitkbcompare.

As indicated by its title, awesome-split-keyboards is an awesome list of split keyboards 50 examples strong. Every split we’ve come across seems to be represented here, many with at least an image or two along with links to more information about how to build or buy the model in question. If that’s not enough, the bottom of the page has a wealth of background information about building or buying your own.

But before making such an important decision it’s important to make sure the keyboard in question will be a good fit in the hands. This is where splitkbcompare comes in, providing a visualization of many popular split layouts. If we hadn’t just found awesome-split-keyboards this filterable list and wide selection would have been the highlight here. But what does stand out is the ability to generate 1:1 scale printouts of the layouts in question, even stacking them for comparison, allowing a prospective buyer get a hands on feel for what they’re considering.

Not enough clackin’ action? Recently we’ve been producing a fierce amount of keyboard related content, of particular highlight is [Kristina Panos’]’ series called Inputs of Interest. Earlier in the summer she even built her own Ergodox split keeb.

DIY HID, OMG!

William English, one of the creators of the mouse back in the 60s, passed away last week. And that got me thinking of how amazing it would have been to be in the place that was inventing what would become modern computing interfaces. What a special time! Of course, they probably had no idea.

From here, it looks like the mouse changed everything, but you have to realize that they were working in a world with light-pens, where you could actually draw on the screen. In contrast, the mouse seems positively non-futuristic. They must have known they’d come up with an improvement over the status quo, but did they know they’d created a revolution?

So where has the revolutionary spirit in DIY human interface devices gone? I’d claim it’s still alive and kicking. Indeed our own Kristina Panos has a series called “Inputs of Interest” and we’ve seen a ton of DIY keyboards of late. Then there are many varieties of dial inputs. I used to have a dedicated scroll wheel made out of a hard-drive platter, and when I was reading lots of PDFs on-screen, I have to say it earned its desk-space. Heck, we’ve even seen people make their own mouse.

But what I love about the story of the development of the mouse is that they asked the question “what is the best way to locate a point on a screen” and tried to answer it. Half of their success is probably in simply asking the right question, and the other half in prototyping something half-workable. My gut says that we don’t have inputs figured out 100% on mobile yet. This sounds like a job for Hackaday. What’s the next big human-interface design need? And have you got any crazy ideas to solve it?

Hackaday Remoticon

And this week, we announced the Hackaday Remoticon, our shelter-in-place version of the Supercon. It’s going to take place in November as usual, but online instead of IRL.

The good news? It’s going to be chock full of workshops, all streamed online and recorded for posterity. And for that we need your proposals. If you’d like to teach a group of distributed hackers learning your favorite techniques and tricks, this is your chance!

The bad news is of course that we won’t get to see you all in person. That’s going to make the 2021 Hackaday Supercon seem even more super.

Hackaday Podcast 070: Memory Bump, Strontium Rain, Sentient Solder Smoke, And Botting Browsers

Hackaday editors Elliot Williams and Mike Szczys bubble sort a sample set of amazing hacks from the past week. Who has even used the smart chip from an old credit card as a functional component in their own circuit? This guy. There’s something scientifically devious about the way solder smoke heat-seeks to your nostrils. There’s more than one way to strip 16-bit audio down to five. And those nuclear tests from the 40s, 50s, and 60s? Those are still affecting how science takes measurements of all sorts of things in the world.

Hackaday Podcast 064: The COBOL Cabal, The Demoscene Bytes, And The BTLE Cure

Hackaday editors Elliot Williams and Mike Szczys pan for gold in a week packed with technological treasure. The big news is Apple/Google are working on contact tracing using BTLE. From adoption, to privacy, to efficacy, there’s a lot to unpack here and many of the details have yet to take shape. Of course the episode also overflows with great hacks like broken-inductor bike chain sensors, parabolic basketball backboards, bizarre hose clamp tools, iron-on eTextile trials, and hot AM radio towers. We finish up discussing the greatest typing device that wasn’t, and the coming and going of the COBOL crisis.

Hackaday Podcast 056: Cat Of 9 Heads, Robot Squats, PhD In ESP32, And Did You Hear About Sonos?

Hackaday editors Elliot Williams and Mike Szczys gab on great hacks of the past week. Did you hear that there’s a new rev of the Pi 4 out there? We just heard… but apparently it’s release into the wild was months ago. Fans of the ESP8266 are going to love this tool that flashes and configures the board, especially for Sonoff devices. Bitluni’s Supercon talk was published this week and it’s a great roadmap of all the things you should try to do with an ESP32. Plus we take on the Sonos IoT speaker debacle and the wacky suspension system James Bruton’s been building into his humanoid robot.
