Like pretty much every other big conference, the Chaos Communication Conference is going virtual this year. What was supposed to be 37C3 has been rebranded as rC3, the remote Chaos Experience. It’s understandable, as a 17,000 person live event would have not only been illegal but a bit irresponsible in the current environment. The event appears to be a hybrid of small local events hosted in hackerspaces linked with streamed talks and a program of workshops and “online togetherness.” rC3 is slated to run in the week between Christmas and New Year, and it seems like a great way to wrap up 2020.
Speaking of remote conferences, don’t forget about our own Remoticon. While it won’t be quite the same as everyone getting together in sunny — historically, at least — Pasadena for a weekend of actual togetherness, it’s still going to be a great time. The event runs November 6 to 8; we’ve had a sneak peek at the list of proposed workshops and there’s some really cool stuff. Prepare to be dazzled, and make sure you keep up on the Remoticon announcements — you really don’t want to miss this.
That was a close shave! On Tuesday, asteroid 2011 ES4 passed really close to the earth. JPL’s close approach data pegs its nominal distance from earth at about 0.00081083276352288 au! Yeah, we had to look it up too: that’s around 75,000 miles (120,000 kilometers), just ten times the diameter of the earth and only about one-third the distance from the earth the moon. It got within about 52,000 miles of the moon itself. Bookworms who made it all the way through Seveneves are surely sweating right now.
There’s a low current arms race when it comes to lighting up LEDs. The latest salvo in the field comes from [Christoph Tack] who boasts a current of 1.36 µA at 3 V for a green LED that is roughly 10x brighter than a phosphorescent watch dial. Of course, the TritiLED is the design being chased, which claims to run 17.6-20.2 years on a single CR2032 coin cell.
Proving once again that Hanna and Barbera were indeed future-tech prophets, flying cars are now a thing. Sky Drive Inc. made a four-minute test flight of a single passenger octo-rotor aircraft. Like a motorcycle of the sky (and those are a thing too) this thing is single-passenger and the cockpit is open air. The CNN article mentions that “The company hopes to make the flying car a part of normal life and not just a commodity”. Yeah, we’re sure they do, but in an age when electric cars are demonized for ranges in the low hundreds of miles, this is about as practical for widespread use as self-balancing electric unicycles.
Google and Apple built a COVID-19 contact tracing framework into their mobile platforms but stopped short of building the apps to actually do the work, anticipating that governments would want to control how the apps worked. So was the case with the European tracing app as Elliot Williams recently covered in this excellent overview. However, the United States has been slower to the game. Looks like the tech giants have become tired of waiting and have now made it possible for the framework itself to work as a contact tracing mechanism. To enable it, local governments need to upload a configuration file that sets parameters and URLs that redirect to informational pages from local health departments, and users must opt-in on their phone. All other tracing apps will continue to function, this is meant to add an option for places that have not yet adopted/developed their own app.
And finally, it’s time to take back responsibility for your poor spelling. Auto-correct has been giving us sardines instead of teaching how to fish for them ourselves. That ends now. The Autocorrect Remover is an extension for Google Docs that still tells you the word is wrong, but hides the correct spelling, gamifying it by having you guess the right spelling and rewarding you with points when you get it right.
Tech history is rife with examples of bizarre product demos, but we’ve got to think that Elon Musk’s Neuralink demo this week will have to rank up there with the weirdest of them. Elon’s job here was to sell the proposition that having a quarter-sized plug removed from your skull by a surgical robot and having it plunge 1,024 tiny wires into your gray matter will be totally normal and something that all the cool kids will be doing someday. We watched the 14-minute supercut of the demo, which went on for considerably longer than that due to the realities of pig wrangling, and we remain unsold on the technology. Elon selling it as “a Fitbit in your skull, with tiny wires” probably didn’t help, nor did the somewhat terrifying appearance of the surgical robot needed to do the job. On the other hand, Gertrude the Bionic Pig seemed none the worse for her implant, which was reportedly wired to her snout and sending data wirelessly. The demonstration of reading joint positions directly from the brain was honestly pretty neat. If you want to dive deeper into Neuralink, check out Maya’s great article that separates fact from science fiction.
Jerry Carr, NASA astronaut and commander of the third and final crewed Skylab mission, passed away this week at the age of 88. Carr’s Skylab 4 mission was record-breaking in 1974, with the three astronauts living and working in the orbiting workshop for 84 days. The mission contributed a vast amount of information on space medicine and the human factors of long-duration spaceflight. Carr retired from NASA in 1977 and had a long career as an engineer and entrepreneur. It’s sad to lose yet another of the dwindling number of heroes remaining from NASA’s manned-flight heyday.
Speaking of spaceflight, the closest most of us DIYers can get to space is likely courtesy of a helium-filled balloon. If you’ve ever considered sending something — or someone — aloft, you’ll find this helium balloon calculator an invaluable tool. Just plug in the weight of your payload, select from a few common balloon sizes, and the calculator will tell you how many you need and how much gas it will take to fill them. It’s got a second section that tells you how many more balloons it’ll take to get to a certain altitude, should merely getting off the ground not be enough for you.
If 2020 has proven anything, it’s that time is, at best, a negotiable concept. Improbably, September is only a day away, after an August that somehow took forever to go by in the blink of an eye. With that in mind, October is OSHWA’s Open Hardware Month, with this year’s theme being “Label and Certify”. We’re a little bit in love with the Open Hardware Facts generator, which takes your open-source hardware, software, and documentation license and generates a USDA “Nutrition Facts”-style label for your product. They’ve also added tools to make it easier to get OSHWA certification for your project.
And finally, what would it be like to pilot a giant exoskeleton? Like, a 9,000 pound (4,100 kg), quadrupedal all-terrain beast of a mech? Turns out you can (theoretically) find out for yourself courtesy of Furrion Exo-Bionics and their monster mech, dubbed Prosthesis. The machine has been in development for a long time, with the vision of turning mech racing into the next big thing in sports entertainment. Their Alpha Mech Pilot Training Program will allow mere mortals to learn how to pilot Prosthesis at the company’s proving ground in British Columbia. Details are sparse, so caveat emptor, but it sure looks like fun.
Apple, the world’s first trillion-dollar company — give or take a trillion — has built a bit of libertarian cachet by famously refusing to build backdoors into their phones, despite the entreaties of the federal government. So it came as a bit of a surprise when we read that the company may have worked with federal agents to build an “enhanced” iPod. David Shayer says that he was one of three people in Apple who knew about the 2005 program, which was at the behest of the US Department of Energy. Shayer says that engineers from defense contractor Bechtel, seemed to want to add sensors to the first-generation iPod; he was never clued in fully but suspects they were adding radiation sensors. It would make sense, given the climate in the early 2000s, walking down the street with a traditional Geiger counter would have been a bit obvious. And mind you, we’re not knocking Apple for allegedly working with the government on this — building a few modified iPods is a whole lot different than turning masses of phones into data gathering terminals. Umm, wait…
A couple of weeks back, we included a story about a gearhead who mounted a GoPro camera inside of a car tire. The result was some interesting footage as he drove around; it’s not a common sight to watch a tire deform and move around from the inside like that. As an encore, the gearhead in question, Warped Perception, did the same trick bit with a more destructive bent: he captured a full burnout from the inside. The footage is pretty sick, with the telltale bubbles appearing on the inside before the inevitable blowout and seeing daylight through the shredded remains of the tire. But for our money, the best part is the slo-mo footage from the outside, with the billowing smoke and shredded steel belts a-flinging. We appreciate the effort, but we’re sure glad this guy isn’t our neighbor.
Speaking of graphic footage, things are not going well for some remote radio sites in California. Some towers that host the repeaters used by public service agencies and ham radio operators alike have managed to record their last few minutes of life as wildfires sweep across the mountains they’re perched upon. The scenes are horrific, like something from Dante’s Inferno, and the burnover shown in the video below is terrifying; watch it and you’ll see a full-grown tree consumed in less than 30 seconds. As bad as the loss of equipment is, it pales in comparison to what the firefighters face as they battle these blazes, but keep in mind that losing these repeaters can place them in terrible jeopardy too.
Potentially bad news for those of us who prefer not to be assimilated into the Google hive mind: Mozilla seems to be on the rocks. Citing revenue problems, the maker of Firefox and other popular tools will be trimming 250 employees, about a quarter of its workforce, and shuttering its office in Taipei. CEO Mitchell Baker specifically mentioned that “development tools, internal tooling, and platform feature development” in the Firefox team would see reduced investment. Like a lot of companies do these days, she managed to blame COVID-19 for the company’s woes. That seems a little specious to us, but whatever the reason for the downturn in revenue, here’s hoping that Mozilla can keep Firefox alive.
Speaking of our evil overlords, looks like it another one of those “oopsies” moment for Google when it “accidentally” activated some of its smart speakers to listen into household events without the wake word. In this case, a user reported getting a text about a smoke alarm going off in their home. The alarm was not a surprise, since the user was cooking at the time, but the notification was, since they didn’t opt into that particular service. Google’s response was that an update pushed to the speaker accidentally activated that feature, a situation that they say has since been rectified. To be clear, this is an interesting feature and one of the more compelling use cases we’ve seen for a smart speaker, but it’s something we’d certainly want to sign off on before it’s activated. Yes, accidents happen, but these kinds of accidents seem to happen to Google an awful lot lately.
We’ve probably all had the experience over the last few months of being in public when the urge to cough hits. Masked or not, you struggle to fight back the tickle, lest someone hear you and think you’re infected. But now it’s possible for a computer to cough-shame you, thanks to a deep learning cough locater. The model was trained against recordings of people coughing and is coupled to an acoustic camera, which identifies the cougher with a bounding box and a contour image of the cough which looks for all the world like a virtual cloud of microbes. It’s genuinely interesting technology, sort of the public health version of ShotSpotter, but we doubt it’ll be of much practical use in public; if you want to find someone who has just coughed, someone acting like this will likely already be on the case.
Modern jet fighter technology is advancing rapidly, so much so that the forces they can apply during extreme maneuvers can quickly be lethal to pilots. Given that humans aren’t likely to evolve the ability to resist turning into a puddle of goo under high g-forces anytime soon, fighters of the future will likely incorporate AI of some sort. To prepare for that eventuality, the Defense Advanced Research Projects Agency (DARPA) is running some AI fighter competitions this week that really look interesting. Dubbed Alpha Dogfight Trials, the challenge starts with simulated dogfights between AI systems. The winner of those rounds will go up against a human pilot in the final match, which will be streamed live with commentary and multi-screen coverage. You need to register to get in on the action, and time is limited.
And finally, let these three words roll around in your head for a minute: robotic chameleon tongue. It’s actually nowhere near as disturbing as it sounds, since at its heart the “Snatcher” is actually just a beefed-up tape measure. Designed for remote retrieval tasks, the Snatcher can shoots it steel proboscis out almost a meter in just 600 milliseconds. Its designers envision uses for it on drones, but we can see it potentially being deployed on satellites too. It shouldn’t be too hard to build something like this at home, either.
We regret to admit this, but we completely missed the fact that Windows 10 turned five years old back in March. Granted, things were a little weird back then — at least it seemed weird at the time; from the current perspective, things were downright normal then. Regardless, our belated congratulations to Microsoft, who, like anyone looking after a five-year-old, spends most of their time trying to keep their charge from accidentally killing itself. Microsoft has done such a good job at keeping Windows 10 alive that it has been installed on “one billion monthly active devices”. Of course, back in April of 2015 they predicted that the gigainstall mark would be reached in 2018. But what’s a couple of years between friends?
Of all the things that proved to be in short supply during the pandemic lockdowns, what surprised us most was not the toilet paper crunch. No, what really surprised us was the ongoing webcam supply pinch. Sure, it makes sense, with everyone suddenly working from home and in need of a decent camera for video conferencing. But we had no idea that the market was so dominated by one manufacturer — Logitech — that their cameras could suddenly become unobtainium. Whatever it is that’s driving the shortage, we’d take Logitech’s statement that “demand will be met in the next 4-6 weeks” with a huge grain of salt. After all, back-to-school shopping is likely to look vastly different this year than in previous years.
Speaking of education, check out the CrowPi2 STEM laptop. On the one hand, it looks like just another Raspberry Pi-based laptop, albeit one with a better level of fit and finish than most homebrew Pi-tops. With a Raspberry Pi 4b on board, it can do all the usual stuff — email, browse the web, watch videos. The secret sauce is under the removable wireless keyboard, though: a pretty comprehensive electronics learning lab. It reminds us of the Radio Shack “150-in-One” kits that so many of us cut our teeth on, but on steroids. Having a complete suite of modules and a breadboarding area built right into the laptop needed to program it is brilliant, and we look forward to seeing how the Kickstarter for this does.
Exciting news from Hackaday Superfriend Chris Gammell — he has launched a new podcast to go along with his Contextual Electronics training courses. Unsurprisingly dubbed the Contextual Electronics Podcast, he already has three episodes in the can. They’re available as both video and straight audio, and from the few minutes we’ve had to spend on them so far, Chris has done a great job in terms of production values and guests with Sophy Wong, Stephen Hawes, and Erik Larson leading off the series. We wish him luck with this new venture, and we’re looking forward to future episodes.
One of the best things about GoPro and similar sports cameras is their ability to go just about anywhere and show things we normally don’t get to see. We’re thinking of those gorgeous slo-mo selfies of surfers inside a curling wave, or those cool shots of a skier powder blasting down a mountain slope. But this is the first time we’ve seen a GoPro mounted inside a car’s tire. The video by the aptly named YouTuber [Warped Perception] shows how he removed the tire from the wheel and mounted the camera, a battery pack, and an LED light in the rim, then remounted the tire. The footage of the tire deforming as it contacts the ground is fascinating but oddly creepy. It sort of reminds us a little of the footage from cameras inside the Saturn V fuel tanks — valuable engineering information to be sure, but forbidden in some way.
If you somehow manage to mentally separate yourself from the human tragedy of the COVID-19 pandemic, it really has provided a fascinating glimpse into how our planet operates, and how much impact seven billion people have on it. Latest among these revelations is that the shutdowns had a salubrious effect in at least one unexpected area: solar power. Researchers found that after the Indian government instituted mandatory lockdowns in March, output from solar power installations in Delhi increased by more than eight percent. The cause: the much-diminished smog, which let more sunlight reach solar panels. We’ve seen similar shutdown-related Earth-impact stories, from decreased anthropogenic seismicity to actually being able to see Los Angeles, and find them all delightfully revealing.
Remember Google Glass? It’s hard to forget, what with all the hype leading up to launch and the bitter disappointment of realizing that actually wearing the device wouldn’t go over well in, say, a locker room. That said, the idea of smart glasses had promise, and several startups tried to make a go of combining functionality with less out-there styling that wouldn’t instantly be seen as probable cause for being a creep. One such outfit was North, who made the more-or-less regular looking (if a bit hipsterish) Focals smart glasses. But alas, North was bought out by Google back in June, and as with so many things Google acquires, Focals smart glasses are being turned off. Anyone who bought the $600 specs will reportedly get their money back, but the features of the smart glasses will no longer function. Except, you know, you’ll still be able to look through them.
It looks like someone has finally come up with a pretty good use case for the adorably terrifying robot mini-dogs from Boston Dynamics. Ford Motors has put two of the yellow robots to work in their sprawling Van Dyke Transmission Plant in Michigan. Dubbed Fluffy and Spot (aww), the dogs wander around the plant with a suite of cameras and sensors, digitally mapping the space to prepare for possible future modifications and expansions. The robots can cover a lot of ground during the two hours that their batteries last, and are even said to be able to hitch a ride on the backs of other robots when they’re tuckered out. Scanning projects like these can keep highly trained — and expensive — engineers busy for weeks, so the investment in robots makes sense. And we’re sure there’s totally no way that Ford is using the disarmingly cute robo-pets to keep track of its employees.
We all know that the Linux kernel has some interesting cruft in it, but did you know that it can actually alert you to the fact that your printer is aflame? We didn’t either until Editor-in-Chief Mike Szczys shared this reddit post that details the kernel function lp_check_status and how it assumes the worst if it detects the printer is online but also in “check mode.” The Wikipedia entry on the “lp0 on fire” error message has some interesting history that details how it’s not as implausible as it might seem for a printer, especially one in the early 1970s, to burst into flames under the right conditions. A toner fuser bar running amok on a modern laser printer is one thing, but imagine a printer with a fusing oven running out of control.
And finally, because 2020 is apparently the gift that can’t stop giving, at least in the weirdness department, the US Department of Defense let it slip that the office charged with investigating unidentified aerial phenomena is not quite as disbanded as they once said it was. Reported to have been defunded in 2017, the Advanced Aerospace Threat Identification Program actually appears to live on, as the Unidentified Aerial Phenomena Task Force, operating out of the Office of Naval Intelligence. Their purpose is ostensibly to study things like the Navy videos of high-speed craft out-maneuvering fighter jets, but there are whispers from former members of the task force that “objects of undetermined origin have crashed on earth with materials retrieved for study.” All this could just be a strategic misdirection, of course, but given everything else that has happened this year, we’re prepared to believe just about anything.
