Neutrino Hunters Hack Chat

Join us on Wednesday, January 17 at noon Pacific for the Neutrino Hunters Hack Chat with Patrick Allison!

It’s a paradox of science that the biggest of equipment is needed to study the smallest of phenomena. The bestiary of subatomic particles often requires the power and dimension of massive accelerators to produce, and caverns crammed with racks full of instruments to monitor their brief but energetic lives. Neutrinos, though, are different. These tiny, nearly massless, neutral particles are abundant in the extreme, zipping through space from sources both natural and artificial and passing through normal matter like it isn’t even there.

That poses a problem: how do you study something that doesn’t interact with the stuff you can make detectors out of? There are tricks that neutrino hunters use, and most of them use very, VERY big instruments to do it. Think enormous tanks of ultrapure water or a cubic kilometer of Antarctic ice, filled with photomultiplier tubes to watch for the slightest glimmer of Cherenkov radiation as a neutrino passes by.

join-hack-chatNeutrino hunting is some of the biggest of Big Science, and getting all the parts to work together takes some special engineering. Patrick Allison has been in the neutrino business for decades, both as a physicist and as the designated guru who keeps all the electronics humming. He’ll join us on the Hack Chat to talk about the neutrino hunting trade, and what it takes to keep the data flowing.

The Superconference Badge Hack Chat

Join us on Wednesday, December 20 at noon Pacific for the Superconference Badge Hack Chat with Elliot Williams and Voja Antonic!

There’s a lot to get excited about when October rolls around and you know Supercon is right around the corner. Catching up with old friends, making new ones, hanging out in the alley, catching the talks, and of course the food. But at the top of everyone’s list has to be The Badge. Finding out what cool bit of technology is going to be built into the badge and figuring out exactly how you’re going to hack it once you get your greedy mitts on it — now that’s excitement!

join-hack-chatThe 2023 Supercon badge was quite a hit, at least judging by all the cool hacks that people came up with. But what exactly went into getting this badge into everyone’s hands? A lot of work, that’s what, along with a lot of blood, sweat, and tears. And while there was plenty of work to go around and a lot of shoulders to the wheel, a lot of the work fell to Elliot and Voja. They’re going to be hopping into the last Hack Chat of the year to talk all about this amazing badge, from concept to conference, and all the hellish steps in between.

The Hoarder’s Dilemma Hack Chat

Join us on Wednesday, December 6 at noon Pacific for the The Hoarder’s Dilemma Hack Chat with Gabe Emerson!

There’s a lot to be said for the power of a well-stocked junk bin. It’s almost a magical thing, being able to dive into a random box and retrieve just the right part to perform a needful repair or to complete a project without the need to hit the web or hop in the car for a trip to the hardware store. For those who pride themselves on their resourcefulness, it can be a heady experience indeed.

But as with everything, such feats of fix-it come at a price. That little squirt of dopamine that comes from having just the right thing can make your monkey brain fixate on a simple equation: “More stuff is better stuff.” The higher and deeper your stash, the better your chances of having what you need, assuming you can find it, of course. This way lies madness, and perhaps an appearance on a reality TV show.

join-hack-chatIs there a better way? It’s hard to say, but we figured it would be a good idea to loop in someone with a lot of experience collecting junk that somehow finds its way into some pretty cool projects. Gabe Emerson runs the popular and aptly named “saveitforparts” channel over on YouTube, and fancies himself an accomplished hoarder. We’d have to agree, given his recent 1,000-mile drive to pick up a used geodesic dome, or his ever-increasing collection of RV satellite dishes, which he somehow puts to good use. His junk collection is pretty epic; he even has a whole piece of property devoted to the larger pieces of his collection, like an entire monorail train. He seems uniquely qualified to discuss the “Hoarder’s Dilemma” and the painful process of deciding what stays and what goes.

Satellite Hunting Hack Chat

Rescheduled — note new date!


Join us on Wednesday, October 18 at noon Pacific for the Satellite Hunting Hack Chat with Scott Tilley!

From the very first beeps of Sputnik, space has primarily been the domain of nations. It makes sense — for the most part, it takes the resources of a nation to get anything of appreciable size up out of the gravity well we all live in, but more importantly, space is the highest of high ground, and the high ground has always been a place of advantage to occupy. And so a lot of the hardware we’ve sent upstairs in the last 70 years has been in the national interest of this or that country.

join-hack-chatA lot of these satellites are — or were, at least — top secret stuff, with classified payloads, poorly characterized orbits, and unknown communications protocols. This can make tracking them from the ground a challenge, but one that’s worth undertaking. Scott Tilley has been hunting for satellites for years, writing about his exploits on the Riddles in the Sky blog and sometimes being featured on Hackaday. After recently putting his skills to work listening in on a solar observation satellite as its orbit takes it close to Earth again, we asked him to stop by the Hack Chat to share what he’s learned about hunting for satellites, both long-lost and intentionally hidden. Join us as we take a virtual trip into orbit to find out just what’s going on up there.

ISS Mimic Brings Space Station Down To Earth

Built at a cost of more than $150 billion over the last twenty-five years, the International Space Station is arguably one of humanity’s greatest engineering triumphs. Unfortunately, unlike Earthly construction feats such as the Hoover Dam, Burj Khalifa, or the Millau Viaduct, you can’t visit it in person to really appreciate its scale and complexity. Well, not unless you’ve got the $50 million or so to spare to buy a seat on a Dragon capsule.

Which is why the team behind the ISS Mimic project are trying to make the ISS a bit more relatable. The open source project consists of a 3D printable 1:100 model of the Station, which is linked to the telemetry coming down from the real thing. A dozen motors in the model rotate the solar arrays and radiators to match the positions of their full-scale counterparts, while LEDs light up to indicate the status of various onboard systems.

To learn more about the ISS Mimic, team members Bryan Murphy, Sam Treadgold, and Tristan Moody stopped by this week’s Hack Chat to bring us up to speed on the past, present, and future of this fascinating project.

Modeling Space Hack Chat

Join us on Wednesday, October 4 at noon Pacific for the Modeling Space Hack Chat with Bryan Murphy and Sam Treadgold!

We’re going to go out on a limb here and guess that a fair number of Hackaday readers went through a phase of model building growing up. To further push out that branch, we’ll further guess that some of those models included spacecraft, both real and imaginary. And with good reason — you don’t get to space without some interesting engineering, a lot of which is reflected in the design of the vehicles intended to get there. Rockets are cool, satellites are cooler still, and if you can’t actually go to space yourself, or at least be the person building the actual hardware, at least you can build a model and dare to dream.

But while a model on a stand or hanging from the ceiling on fishing line can certainly stimulate the imagination, wouldn’t it be better if a model did something? Bryan Murphy and Sam Treadgold think so, which is why they’ve been working on the “ISS Mimic,” which we recently featured. The 3D-printed 1:100 scale model of the International Space Station is equipped with servos that move the station’s solar panels in real-time based on publically available telemetry. It’s way more engaging than a static model, especially for kids just getting into STEM and related fields.

join-hack-chatBryan and Sam will stop by the Hack Chat to talk not just about the ISS Mimic, but about everything that has to do with modeling space. Who wouldn’t love a desktop version of a Martian or lunar rover keeping pace with its full-scale counterpart? And wouldn’t it be great to be able to visualize just how far away Voyager is right now? If it’s out there, we should be able to bring it home, at least in model form.

Keebin’ With Kristina Hack Chat

Join us on Wednesday, September 27 at noon Pacific for the Keebin’ with Kristina Hack Chat with our own Kristina Panos!

When you think about it, wiggling your fingers over a bunch of magic chiclets is a pretty strange gateway to the written word. And yet, here we sit a hundred-odd years after someone first decided that the same basic interface used to run pianos and harpsichords for centuries would be a fantastic model for mechanizing the whole writing thing. Just because it makes perfect sense thanks to the outsized portion of our brains dedicated to the motor and sensory functions of our wonderfully complex and versatile hands doesn’t mean it’s not weird.

join-hack-chatStill and all, it seems like there could be some room for improvement in the basic design of keyboards. We could probably do with something that makes typing easier, results in less repetitive strain, or is just more fun to do. Pushing back on the traditional and boring designs of the past is where we find the strange breed of keyboard builders and modders that our very own Kristina Panos counts herself part of. You know here from her popular “Keebin’ with Kristina” series, and now we’ve coaxed her into checking into the Hack Chat to talk to all the rest of us keyboard-minded individuals. If you’ve ever thought that there has to be a better way to enter text, or even just something a little bit different, you’ll want to come along and join the conversation.
