Hackaday Links: September 20, 2020

The announcement of Autodesk’s changes to the Fusion 360 personal use license terms this week caused quite a dustup. Our article on the announcement garnered a lot of discussion and not a few heated comments. At the end of the day, though, Autodesk is going to do what it’s going to do, and the Fusion 360 user community is just going to have to figure out how to deal with the changes. One person who decided to do something other than complain is Justin Nesselrotte, who came up with a quick and easy bulk export tool for Fusion 360. This gets to the heart of the issue since the removal of export to STEP, IGES, and SAT files is perhaps the most painful change for our community. Justin’s script automatically opens every design and exports it to the file type of your choice. Since the license changes go into effect on October 1, you’d better get cracking if you want to export your designs.

Over on Twitter, Hackaday superfriend Timon gives us a valuable lesson in “you get what you pay for.” He found that a bunch of his header pin jumper cables weren’t even remotely assembled properly. The conductors of the jumper wire were only loosely inserted into the terminal’s crimp, where apparently no crimping pressure had been applied. The wires were just rattling around inside the crimp, rather than making sold contact. We’ve covered the art and science of crimping before, and it’s pretty safe to say that these jumpers are garbage. So if you’re seeing weird results with a circuit, you might want to take a good, close look at your jumpers. And as always, caveat emptor.

The GNU Radio Conference wrapped up this week, in virtual format as so many other conferences have been this year, and it generated a load of interesting talks. They’ve got each day’s proceedings over on their YouTube channel, so the videos are pretty long; luckily, each day’s stream is indexed on the playbar, so along with the full schedule you can quickly find the talks you’re interested in. One that caught our eye was a talk on the Radio Resilience Competition, a hardware challenge where participants compete head-to-head using SDRs to get signals through in an adversarial environment. It sounds like a fascinating challenge for the RF inclined. More details about registering for the competition can be had on the Radio Resilience website.

You know those recipe sites that give you a few choices on what to make for dinner based on the ingredients you have on hand? We always thought that was a clever idea, and now something like it has come to our world. It’s called DIY Hub, and it aims to guide makers toward projects they can build based on the parts they have on hand. Users create projects on the site, either hosting the project directly on the site or providing a link to projects on another site. Either way, the project’s BOM is cataloged so that users can find something to build based on parts stored in their “Garage”. Granted, most of us suffer from the exact opposite problem of not knowing what to build next, but this could be an interesting tool for stimulating the creative process, especially for teachers and parents. It’s currently in beta, and we’d love to see a few Hackaday.io projects added to the site.

And finally, we got a tip to an oldie but a goodie: How to Build a Castle. No, we don’t expect to see a rash of 13th-century castle builds gracing our pages anytime soon — although we certainly wouldn’t be opposed to the idea. Rather, this is a little something for your binge-watching pleasure. The BBC series, which was actually called Secrets of the Castle, was a five-part 2014 offering that went into great detail on the construction of Guédelon Castle, an experimental archaeology project in France that seeks to build a castle using only the materials and methods available in the 1200s. The series is hosted by historian Ruth Goodman and archaeologists Peter Ginn and Tom Pinfold, and it’s great fun for anyone interested in history and technology.

  1. If you are not crimping it yourself, then good luck on the crappy wires that these Chinese cables are using. They use very few copper strands and will cause you trouble in the long run. Would you rather debug the wires or your prototype?

    As for jumper wires, how lazy can you be? Just use solid gauge wire, cut to right length and strip. It is cheaper and cleaner.

    1. UTP wires tend to corrode pretty quickly, use them for one project, put them in the box and open box in a month, they’re corroded. Ofcourse you can make new batch every time you do something with breadbord, as those wires are dirt cheap, but it takes some time to prepare them.

    2. There’s a couple of telco B-boxes within walking distance of me, when they take out old wire, they just leave it on the ground. This is the good stuff, I think it’s 20ga solid, even a one-inch piece can be bent into a short jumper for a breadboard. And they come in interesting colors, blue, violet, yellow, black, but not much red. As if didn’t already have way too much 22ga from decades ago.
      But I would never get those jumpers with cheap stamped male pins, just the pins themselves clearly don’t have any strength, even before you look at the crimps. Female ends can be gender-changed with a header pin, and the typical “Dupont” style pin with its plastic bit removed can go into bigger plastic blocks from my junk box, such as 5×2 USB headers from old PCs. All it takes is a small straight pin to lift the little latch thing.

  2. I once got a last minute project where I had to hot wire stuff, they already had all the materials, and got it handed to me, it had some crappy jumper wires and caused a lot of issues, luckily I had my soldering iron with me to just solder the connectors after I figured out what the problem was.

  3. The problem is do you get what you pay for? I’ve seen stuff in the dollar store that is identical to stuff more “reputable” stores are selling for upwards of $20, so you might get what you pay for but don’t count on it.

  4. This guy built a cathedral 100+feet high with domes and crypts and all with scrap/donated building materials with no experience or education in architecture or engineering over the last 50 yrs. I mean it’s probably got a few structural code violations but not bad all things considered. He’s kinda my hero as I often find myself taking on projects and tasks suitable for teams of experienced professionals with only myself and a heart filled with foolish ambition and the notion “hmmm I’ll figure it all out along the way”
