DIY Picosatellites Hack Chat

Join us on Wednesday, June 21 at noon Pacific for the DIY Picosatellites Hack Chat with Nathaniel Evry!

Building a satellite and putting it in orbit was until very recently something only a nation had the resources to accomplish, and even then only a select few. Oh sure, there were a few amateur satellites that somehow managed to get built on a shoestring budget and hitch a ride into space, and while their stories are deservedly the stuff of legends, satellite construction took a very long time to be democratized.

Fast forward a half-dozen or so decades, and things have changed dramatically. Satellite launches are still complex affairs — it’s still rocket science, after all — but the advent of the CubeSat format and the increased tempo of launches, both national and commercial, has pushed the barriers to private, low-budget launches way, way down. So much so, in fact, that the phrase “space startup” is no longer something to snicker about.

join-hack-chatOne such group of space entrepreneurs is Quub, Inc., a small company in Lancaster, Pennsylvania which is looking to build and fly a constellation of microsatellites to monitor Earth’s environment in real-time. They’re building sats and signing launch deals using consumer-grade technology and modularized construction, and we’re lucky enough to have Nathaniel Evry, their Chief Research Officer, stop by the Hack Chat. If you’ve ever wondered what it takes to build hardware that can stand the rigors of launch and then perform a task in space, you’ll want to tune in for this one.

Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, June 21 at 12:00 PM Pacific time.

You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about.

Passionate Hams Make Their Mark On The Hack Chat

Let’s be honest — there are some not very pleasant stereotypes associated with amateur radio, at least if you ask outsiders. Hams are often thought of as being in two camps: old guys who can’t figure out modern technology or conspiracy theorists who think their knowledge of radio will give them an edge after the world becomes a post-apocalyptic hellscape. We’ll leave it to you to decide which is the worse brush to be painted with.

As is often the case, the best way to fight such ignorance is with education and outreach. Events like our weekly Hack Chat are a perfect platform for that, as it allows the curious to ask questions and get answers directly from subject matter experts. This is precisely why we invited Mark Hughes and Beau Ambur to helm last week’s Chat. The fact that they’re both relatively recent licensees makes them uniquely qualified to shed some light on what it’s like to become part of the ham radio community in the 21st century. As an added bonus, they’re both sharp and articulate technologists — about as far as you can get from the mental image of the doddering old granddad who prefers the simplicity of the Morse key to those newfangled smarty-phones.

Getting Started In Ham Hack Chat

Join us on Wednesday, June 7 at noon Pacific for the Getting Started in Ham Hack Chat with Mark Hughes and Beau Ambur!

If you were to scratch any random hacker from the last 100 years, chances are pretty good you’d find an amateur radio operator just beneath the surface. Radio is the first and foremost discipline where hacking was not only welcomed, but required. If you wanted to get on the air, you sat down with some coils of wire, a few random parts — as often as not themselves homemade — and a piece of an old breadboard, and you got to work. Build it yourself or do without, and when it broke down or you wanted to change bands or add features, that was all on you too.

Like everything else, amateur radio has changed dramatically over the decades, and rolling your own radio isn’t exactly a prerequisite for entry into the ham radio club anymore. Cheap but capable handheld radios are available for a pittance, better quality radios are well within most people’s budget, and commercially available antennas have reduced the need to dabble in that particular black art. The barrier to entry for amateur radio has never been lower; you don’t even have to learn Morse anymore! So why haven’t you gotten a license?

join-hack-chatWhatever your reason for putting off joining the club of licensed amateur radio operators, we’re going to do our best to change your mind. And to help us do that, we’ve asked Mark Hughes (KE6WOB) and Beau Ambur (K6EAU) to swing by the Chat and share their experiences with getting on the air. Both are relatively recent licensees, and they’ll do their best to answer your questions about getting on the air for the first time, to get on your way to building that first radio.

Chatting About The State Of Hacker-Friendly AR Gear

There are many in the hacker community who would love to experiment with augmented reality (AR), but the hardware landscape isn’t exactly overflowing with options that align with our goals and priorities. Commercial offerings, from Google’s Glass to the Microsoft HoloLens and Magic Leap 2 are largely targeting medical and aerospace customers, and have price tags to match. On the hobbyist side of the budgetary spectrum we’re left with various headsets that let you slot in a standard smartphone, but like their virtual reality (VR) counterparts, they can hardly compare with purpose-built gear.

But there’s hope — Brilliant Labs are working on AR devices that tick all of our boxes: affordable, easy to interface with, and best of all, developed to be as open as possible from the start. Admittedly their first product, Monocle, it somewhat simplistic compared to what the Big Players are offering. But for our money, we’d much rather have something that’s built to be hacked and experimented with. What good is all the latest features and capabilities when you can’t even get your hands on the official SDK?

This week we invited Brilliant Lab’s Head of Engineering Raj Nakaraja to the Hack Chat to talk about AR, Monocle, and the future of open source in this space that’s dominated by proprietary hardware and software.

Open-Source AR Hack Chat

Join us on Wednesday, May 31 at noon Pacific for the Open-Source AR Hack Chat with Raj Nakaraja!

We may live in a soup of electromagnetic waves that range in wavelength from the diameter of Jupiter down to a fraction of the radius of a hydrogen atom, but our eyeballs have evolved to only let us sense a tiny slice of that spectrum. That’s too bad, really, because there’s a lot going on in the rest of the spectrum that could potentially inform our ROYGBIV-centric view of the world. Think of the possibilities of being able to see UV the way an insect does, or being able to watch the radiation pattern of an antenna and make adjustments on the fly. Sounds like a job for augmented reality.

join-hack-chatIf seeing the world with different eyes sounds as cool to you as it does to us, you won’t want to miss Raj Nakaraja’s stop by the Hack Chat. Raj is head of engineering at Brilliant Labs, an augmented reality company that’s looking to bring AR into the mainstream. They’ve got some cool ideas about AR, and we’re going to take the opportunity to talk to Raj about open-source AR in general, Brilliant’s products specifically, and how AR can be incorporated into not only our projects, but into our lives as well.

Learning 3D Printing Best Practices From A Pro

It might seem like 3D printing is a thoroughly modern technology, but the fact is, it’s been used in the industry for decades. The only thing that’s really new is that the printers have become cheap and small enough for folks like us to buy one and plop it on our workbench. So why not take advantage of all that knowledge accumulated by those who’ve been working in the 3D printing field, more accurately referred to as additive manufacturing, since before MakerBot stopped making wooden printers?

That’s why we asked Eric Utley, an applications engineer with Protolabs, to stop by the Hack Chat this week. With over 15 years of experience in additive manufacturing, it’s fair to say he’s seen the technology go through some pretty big changes. Hes worked on everything from the classic stereolithography (SLA) to the newer Multi Jet Fusion (MJF) printers, with a recent focus on printing in metals such as Inconel and aluminum. Compared to the sort of 3D printers he’s worked with, we’re basically playing with hot, semi-melted, LEGOs — but that doesn’t mean some of the lessons he’s learned can’t be applied at the hobbyist level.

Design For 3D Printing Hack Chat

Join us on Wednesday, May 24 at noon Pacific for the Design for 3D Printing Hack Chat with Eric Utley!

Like a lot of enabling technologies, 3D printing has had a strange trajectory. It started out as a laboratory oddity, moved on to industrial applications, and finally filtered down to the DIY set, first as scratch-built machines and later as inexpensive commodity printers that can be found almost anywhere. Pretty much everyone who needs a 3D printer now has one.

Not all additive manufacturing technologies are created equal, though, and there are plenty of applications for 3D printed parts where FDM just won’t cut it. Luckily, any of us can get access to the latest and greatest manufacturing technologies through job houses that specialize in everything from metal 3D printing to sheet metal fabrication, CNC machining, and even small-run injection molding. We may not be able to afford any of the machines, but in a lot of cases we can afford to rent time of them and get high-quality parts quickly.

join-hack-chatBut that raises another question: Is my design ready for printing? What works on an Ender on your shop bench might not quite translate to the latest SLS printer, and sending off an iffy design could just end up wasting time and money. Whether you’re sending your designs out and running them up on your own printer, you want to know what you’re doing will work. That’s why we’ve asked Eric Utley, an applications engineer with Protolabs, to stop by the Hack Chat. With 12 years of additive manufacturing experience, he’ll be able to help you tune up your designs and make sure they’re ready to print.
