A Medieval Gothic Monastery Built Using CAD / CAM

January 13, 2023 by Anool Mahidharia 51 Comments

Just because you’re a monk doesn’t mean you can’t use CAD. The Carmelite monks of Wyoming are building a grandiose Gothic Monastery, and it’s awe inspiring how they are managing to build it.

The Carmelite monks needed a new, larger monastery to house their growing numbers, and found a parcel of land near Meeteetse Creek in Wyoming. The design of their new Gothic monastery was outsourced to an architectural firm. Gothic architecture is characterised by key architectural elements such as pointed arches, large stained glass windows, rib vaults, flying buttresses, pinnacles and spires, elaborate entry portals, and ornate decoration.

After some research, the monks settled on using Kansas Silverdale limestone for the monastery. Cutting and carving the elaborate stone pieces required for such a project, within time and cost constraints, could only be achieved using CNC machines. Hand carving was ruled out as it was a very slow process, would cost a whole lot more, and it wouldn’t be easy to find the artisans for the job. So when it came to shortlisting vendors for the vast amount of stone cutting and carving required for construction, the monks found themselves alarmed at how prohibitively expensive it would turn out to be.

Wizards Slay The Dragon That Lays The Golden Egg

January 11, 2023 by Jonathan Bennett 77 Comments

Hail, and well met adventurers! There’s rumors of dark dealings, and mysterious machinations from that group of Western mystics, Wizards of the Coast (WotC). If this pernicious plot is allowed to succeed, a wave of darkness will spread over this land of Open Source gaming, the vile legal fog sticking to and tainting everything it touches. Our quest today is to determine the truth of these words, and determine a defense for the world of open gaming, and indeed perhaps the entire free world! Beware, the following adventure will delve into the bleak magic of licensing, contract law, and litigation.

Ah, Dungeons and Dragons. The original creation of Gary Gygax, refined by countless others, this table-top role-playing game has brought entertainment and much more to millions of players for years. In 2000, WotC made a decision that opened the mechanics of that universe to everyone. The 3rd Edition of Dungeons and Dragons was released under the Open Gaming License, a very intentional port of Open Source licensing to table-top gaming — obviously inspired by the GNU Public License. Ryan Dancey was one of the drivers behind the new approach, and made this statement about it:

I think there’s a very, very strong business case that can be made for the idea of embracing the ideas at the heart of the Open Source movement and finding a place for them in gaming. […] One of my fundamental arguments is that by pursuing the Open Gaming concept, Wizards can establish a clear policy on what it will, and will not allow people to do with its copyrighted materials. Just that alone should spur a huge surge in independent content creation that will feed into the D&D network.

Ask Hackaday: What’s Your Worst Repair Win?

January 9, 2023 by Dan Maloney 191 Comments

Like many of you, I’ve become the designated “fix-it” person for my family and friends. While it can be a lot of work — I just finished an oil change that required me to lay in a cold, wet driveway and I can’t mention in polite company the substances I was bathed in while fixing a clogged pipe last week — I generally relish my role. I enjoy solving problems, I love working with my hands and my head, and who doesn’t like saving money and time?

But for me, the best part of being the fix-it guy is the satisfaction that comes from doing something others can’t do. I find this especially true with automotive repairs, which conventional wisdom says is strictly the province of factory-trained experts. A little bit of a hero complex, perhaps? Absolutely! After all, I don’t get paid for my repairs, so I’ve got to get a little something for the effort.

This is why a recent pair of unrelated fixes left me feeling thoroughly unsatisfied. Neither of these jobs was a clear win, at least in terms of getting the rush of being able to do something that nobody else could. At best, these were qualified wins, which both still left me feeling a little defeated. And that got me thinking that I’m probably not the only one who has had marginal repair wins like these.

2022: As The Hardware World Turns

January 3, 2023 by Tom Nardi 30 Comments

Well folks, we made it through another one. While it would be a stretch to call 2022 a good year for those of us in the hacking and making community, the light at the end of the tunnel does seem decidedly brighter now than it did this time 365 days ago. It might even be safe to show some legitimate optimism for the year ahead, but then again I was counting on my Tesla stocks to be a long-term investment, so what the hell do I know about predicting the future.

Eh, my kids probably weren’t going to college anyway.

Thankfully hindsight always affords us a bit of wisdom, deservedly or otherwise. Now that 2022 is officially in the rearview mirror, it’s a good time to look back on the highs (and lows) of the last twelve months. Good or bad, these are the stories that will stick out in our collective minds when we think back on this period of our lives.

Oh sure, some might wish they could take the Men in Black route and forget these last few years ever happened, but it doesn’t work that way. In fact, given the tumultuous times we’re currently living in, it seems more likely than not that at some point we’ll find ourselves having to explain the whole thing to some future generation as they stare up at us wide-eyed around a roaring fire. Though with the way this timeline is going, the source of said fire might be the smoldering remains of an overturned urban assault robot that you just destroyed.

So while it’s still fresh in our minds, and before 2023 has a chance to impose any new disasters on us, let’s take a trip back through some of the biggest stories and themes of the last year.

Wear Your Fave Cassette Tapes As A Necklace With This 3D Printed Adapter

December 29, 2022 by Lewin Day 47 Comments

While packing merch for a recent gig, I realised I had the opportunity to do something a little fun. I’d released an album on tape, and spent a little extra to ensure the cassette itself was a thing of beauty. It deserved to be seen, rather than hidden away in a case on a shelf. I wanted to turn this piece of musical media into a necklace.

Of course, cassette tapes aren’t meant to be used in this way. Simply throwing a chain through the cassette would lead to tape reeling out everywhere. Thus, I fired up some CAD software and engineered a solution to do the job! Here’s how I built an adapter to turn any cassette tape into a cool necklace.

Find the design on Thingiverse, and more details below!

Lo-Fi Fun: Beer Can Microphones

December 27, 2022 by Kristina Panos 16 Comments

Sometimes, you just need an easy win, right? This is one of those projects. A couple months back, I was looking at my guitars and guitar accessories and thought, it is finally time to do something with the neck I’ve had lying around for years. In trying to decide a suitable body for the slapdash guitar I was about to build, I found myself at a tractor supply store for LEGO-related reasons. (Where else are you going to get a bunch of egg cartons without eating a bunch of eggs?) I noticed that they happened to also stock ammo boxes. Bam! It’s sturdy, it opens easily, and it’s (very) roughly guitar body shaped. I happily picked one up and started scheming on the way home.

Having never built a cigar box guitar before and being of a certain vintage, I’m inclined to turn to books instead of the Internet, so I stocked up from the library. Among my early choices was Making Poor Man’s Guitars by Shane Speal, who is widely considered to be the guru on the subject. In flipping through the book, I noticed the beer can microphone project and was immediately taken by the aesthetic of some cool old 70s beer can with a 1/4″ instrument jack on the bottom, just asking for some dirty blues to be belted into it. I had to build one. Or twelve.

Your Next Airport Meal May Be Delivered By Robot

December 23, 2022 by Lewin Day 26 Comments

Robot delivery has long been touted as a game-changing technology of the future. However, it still hasn’t cracked the big time. Drones still aren’t airdropping packages into our gutters by accident, nor are our pizzas brought to us via self-driving cars.

That’s not to say that able minds aren’t working on the problem. In one case, a group of engineers are working ton a robot that will handle the crucial duty of delivering food to hungry flyers at the airport.
