Hackaday Links: November 21, 2021

As the most spendiest time of the year rapidly approaches, it’s good to know that your hard-earned money doesn’t have to go towards gifts that are probably still sitting in the dank holds of container ships sitting at anchor off the coast of California. At least not if you shop the Tindie Cyber Sale that started yesterday and goes through December 5. There’s a lot of cool stuff on sale, so it shouldn’t be too hard to find something; to sweeten the deal, Jasmine tells us that there will be extra deals going live on Black Friday and Cyber Monday. But wait, there’s more — follow Tindie on Twitter for bonus discount codes.

Blue is the old black, which was the new blue? At least when it comes to “Screens of Death” it is, since Microsoft announced the Windows 11 BSOD will revert back from its recent black makeover to the more familiar blue theme. You’ll have to scroll down a bit, perhaps three-quarters of the way through the list of changes. Again, the change seems completely cosmetic and minor, but we’d still love to know what kind of research went into making a decision like this.

From the “One Man’s Trash” department, we have a request for help from reader Mike Drew who picked up a bunch — like, a thousand — old tablet computers. They originally ran Windows but they can run Linux Mint just fine, and while they lack batteries and the back cover, they’re otherwise complete and in usable condition, at least judging by the pictures he shared. These were destined for the landfill, but Mike is willing to send batches of 10 — no single units, please — to anyone who can cover the cost of packaging and shipping. Mike says he’ll be wiping the tablets and installing Mint, and will throw in a couple of battery cables and a simple instruction sheet to get you started. If you’re interested, Mike can be reached at michael.l.drew@gmail.com. Domestic shipping only, please. Here’s hoping you can help a fellow hacker reclaim a room in his house.

Answering the important questions: it turns out that Thanos couldn’t have snapped half of the universe out of existence after all. That conclusion comes from a scientific paper, appearing in the Journal of the Royal Society. While not setting out to answer if a nigh-invulnerable, giant purple supervillain could snap his fingers, it’s pretty intuitive that wearing any kind of gloves, let alone a jewel-encrusted metal gauntlet, makes it hard to snap one’s fingers. But the mechanics of snapping is actually pretty cool, and has implications beyond biomechanics. According to the paper, snapping is actually an example of latch-mediated spring actuation, with examples throughout the plant and animal kingdoms, including the vicious “one-inch punch” of the tiny mantis shrimp. It turns out that a properly executed human finger snap is pretty darn snappy — it takes about seven milliseconds to complete, compared to 150 milliseconds for an eye blink.

And finally, it seems like someone over at Id Software is a bit confused. The story began when a metal guitarist named Dustin Mitchell stumbled across the term “doomscroll” and decided that it would make a great name for a progressive thrash metal band. After diligently filing a trademark application with the US Patent and Trademark Office, he got an email from an attorney for Id saying they were going to challenge the trademark, apparently because they feel like it will cause confusion with their flagship DOOM franchise. It’s hard to see how anyone who lived through the doomscrolling years of 2020 and 2021 is going to be confused by a thrash metal band and a 30-year-old video game, but we suppose that’s not the point when you’re an attorney. Trademark trolls gonna troll, after all.

Hackaday Links: December 1, 2019

We can recall a book from our youth that cataloged some of the most interesting airplanes in the world. One particularly interesting beast was dubbed “The Super Guppy”, a hilariously distended cargo plane purpose-built for ferrying Saturn rocket sections around the US in the 1960s. We though the Guppies were long gone, victims like so many other fascinating machines of the demise of the Apollo program. It turns out we were only 4/5 right about that, since one of the original five Super Guppies is still in service, and was spotted hauling an Orion capsule from Florida to Ohio for vacuum testing. The almost 60-year-old plane, a highly modified C-97 Stratofreighter, still has a big enough fan-base to attract 1500 people to brave the Ohio cold and watch it land.

The news this week was filled with reports from Texas of a massive chemical plant explosion that forced the evacuation of 50,000 people from their homes the day before Thanksgiving. The explosion and ensuing fire at the TPC Group petrochemical plant were spectacular; thankfully, there were no deaths and only two injuries reported from the incident. The tie-in to the hacker community lies in what this plant made: butadiene, or synthetic rubber. The plant produced about 16% of the North American market’s supply of butadiene, which we know from previous coverage is one of the polymers in acrylonitrile butadiene styrene, or ABS. It remains to be seen if this will put a crimp in ABS printer filament supplies, or any of the hundreds of products that butadiene is in, including automotive tires and hoses.

Remember when “Cyber Monday” became a thing? We sure do; in the USA, it was supposed to be the first workday back from the Thanksgiving break which would afford those lacking a fast Internet connection at home the opportunity to do online shopping on company time. The idea seems so year 2000 now, but the name stuck, and all kinds of sales and bargains are now competing for your virtual attention and cyber dollars. That includes Tindie, of course, where the Cyber Monday Sale is running through December 6. There’s tons to chose from, including products that got started as Hackaday.io projects and certified open-source hardware products. Be sure to check out the Tindie Twitter feed and blog for extra discount codes, too.

Speaking of gift-giving, we got an interesting tip about a product we never knew we needed. Called “WorkBench”, it’s a modular development system that takes care of an oft-neglected side of prototyping: the physical and mechanical layout. Too often we just start with a breadboard on the bench, and while that’ll do for lots of smaller projects, as the build keeps growing and the breadboards keep coming, things can get out of hand. WorkBench aims to tidy things up by providing a basal platen onto which breadboards, microcontrollers, perfboards, or just about anything else can be snapped. Handles make the whole thing portable, and a clear acrylic cover protects your hard work.

We love to hear stories about citizen science, especially when the amateurs scoop the professionals. Astronomy seems to be a hotbed for this brand of discovery, usually as a lone astronomer peering into the night sky to see a comet or asteroid nobody has seen before. Catching a glitching pulsar in the act is an entirely different level of discovery, though. Back in February, Steve Olney detected a 2.5 parts-per-million increase in the 89-millisecond period of emissions for the Vela pulsar using his RTL-SDR-based observatory. Steve has some fascinating information about pulsars and his observatory on his website. Color us impressed that he was able to pull off this observation without the benefit of millions of dollars in equipment and a giant parabolic dish antenna.

Hackaday Links: November 25, 2018

Bad Obsession Motorsport have been stuffing the engine and suspension from a 4WD Celica into an old Mini since forever. It is a wonderful homage to Police Squad and some of the best machining and fabrication you’ll see on YouTube. The latest episode tackled the electrical system and how to drive an alternator in an extremely cramped engine bay. The solution was a strange flex-shaft confabulation, and now the Bad Obsession Motorsport guys have a video on how they attached an alternator to a car where no alternator should go. It’s forty minutes of machining, go watch it.

Last Friday was Black Friday, and that means it’s time to CONSUME CONSUME CONSUME. Tindie’s having a sale right now, so check that out.

I’m the future of autonomous flight! This week, I got a market research survey in my email from Uber, wanting me to give my thoughts on autonomous ridesharing VTOL aircraft. Uber’s current plan for ridesharing small aircraft involves buying whatever Embraer comes up with (Uber is not developing their own aircraft), not having pilots (this will never get past the FAA), and turning a random parking lot in LA into the busiest airport in the world (by aircraft movements, which again is something that will never get past the FAA). Needless to say, this is criminally dumb, and I’m more than happy to give my thoughts. Below are the relevant screencaps of the survey:

The crux of this survey is basic market research; how much would I pay for a VTOL ride sharing service versus buying a new (autonomous) car versus using an autonomous Uber. You’ve also got a Likert scale thingy asking me if I’m comfortable flying in a battery-powered aircraft. Protip: I highly doubt anyone given this survey has flown in a battery-powered aircraft. Proprotip: the easiest way to screw up the scoring for a Likert scale is to answer ‘1’ for the first question, ‘2’ for the second, etc., and wrap back around to ‘1’ for the sixth question.

Don’t worry, though: I answered all the questions truthfully, but Uber Air will never happen. The FAA won’t let this one fly, and no company will ever carry passengers without a licensed pilot on board.

Contribute To Open Source On #OpenCyberMonday

Today is Cyber Monday, the day when everyone in the US goes back to work after Thanksgiving. Cyber Monday is a celebration of consumerism, and the largest online shopping day of the year. Right now, hundreds of thousands of office workers are browsing Amazon for Christmas presents, while the black sheep of the office are on LiveLeak checking out this year’s Black Friday compartment syndrome compilations.

This is the season of consumption, but there’s still time to give back. We would suggest #OpenCyberMonday, an effort to donate to your favorite Open Source foundations and projects.

It’s not necessary to explain how much we all rely on Open Source software, but it goes even further than the software powering the entire Internet. Hackaday is built on WordPress, and the WordPress Foundation is responsible for very important, very widely used Open Source software. The Wikimedia Foundation is a nonprofit dedicated to the compilation of all knowledge. The Internet Archive is a temporal panopticon, preserving our digital heritage for future generations. The Open Source Hardware Association is doing their best to drag physical objects into the realm of Open Source – a much more difficult task than simply having the idea of Copyleft.

While everyone else is busy buying Internet-connected toasters and wearable electronics, take a few minutes and give a gift everyone can enjoy. Make a donation to the Open Source initiative of your choice A list of these foundations can be found on opensource.org. This isn’t a comprehensive list of worthy Open Source initiatives, so if you have any other suggestions, put it out on the Twitters.
