Once technology that was only available to expensive design teams, and high-end engineering work, 3D printers are now readily available to anyone. Designing a physical prototype with a 3D printer is now something anyone can afford. Did I say anyone? Yes, anyone, even the people trying to build perpetual motion machines. Here’s one on Kickstarter powered by physics. It’s repelling magnets turning wheels.

The study and development of Artificial Intelligence began in the late 1950s and early 1960s. There were conferences, there were talks, colloquium, journals, the works. It was the beginning of a golden age. That came to a screeching halt sometime around 1985. Now, we’re in a new golden age of AI. There’s even a conference. It’s being hosted by [Jeff Bezos], as the alternative, public version of the MARS (for Machine Learning, Automation, Robotics, and Space) conference. Read that link. The phrase, ‘the Bilderberg conference of California’ is in there.

A new Project Binky? Can it be true? Yes, it’s episode 22. The center console is in, the dash is in, and the doors look somewhat finished. What’s the deal this time? A bumpin’ stereo. Wiring! Milliput! It’s English blokes in a shed doing fabrication, your favorite genre of video.

Aaaay, wait a minute. Have you heard about KiCon? Yes, there will be a KiCad user conference. It’s in Chicago, April 26th and 27th, and it’s all about KiCad scripts, settings, tools, techniques, and triumphs. There’s a call for talks, although you shouldn’t try to submit a workshop discussing the difference between ‘Kai-Cad’ and ‘Key-Cad’. That workshop has already been rejected.

Have a 25 meter satellite dish lying around in your backyard? Of course you do. Well, you can hunt for satellites with that thing and a USB TV tuner. The SatNOGS team has been working with a (radio) observatory in the Netherlands, and they’re getting radio signals from overhead satellites. Not bad, and there are, actually, a surprising number of unused large radio dishes out there. Luckily, they’re mostly historic sites.

Once again, Uber found a company to build their ‘air taxis’. This time it’s Boeing. While there are no details on the Boeing bird, I’m going to propose again that Uber buy the Santa Monica airport as a hub for their air taxi program; SMO is going to be shut down anyway, and this is the funniest reality that can come from the idea of an ‘air taxi’ program.

According to ancient astronaut theorists, one of the bigger problems with full-time tech YouTubers (think Dave and Fran here) is the insistence that YouTube suggests conspiracy theory videos as a related video. If you do a video teardown on Apollo flight hardware, you’re going to fall into the same category as people who believe the moon is hollow, people who believe the moon landing was faked, and recently, flat-earthers. This is a ‘bad move’ by YouTube because the Venn diagram of people who want to watch conspiracy videos and people who want to watch teardowns is two circles. It makes community engineering hard, and you get a lot of idiots on YouTube comments. YouTube is now changing the recommendation algorithm. There are other reasons YouTube is doing this, specifically relating to videos that aren’t about weird electronics, but we’re not going to talk about that here, thx.

This week was Winter NAMM, the National Association of… music, something something. That means you can go to Anaheim and check out all the musical instrument related stuff that will be released this year. Think of it as CES, only you don’t get the flu and want to murder everyone, and it’s about guitars and synths instead of Alexas duct taped to Roombas. Here’s what it was like last year, with the tl;dr being a wall of cabs, Euroracks everywhere, and the best way to get started in the industry is to buy some old trademarks, not by actually designing something new. Speaking of, here are some Kay reissues.

So, what’s cool at NAMM this year? Let’s do guitars first. Gibson’s 2019 lineup is not dumb, a reversal of the previous twenty years; There’s a Les Paul Standard with humbuckers or P90s, and there’s a TV Junior. Fender? There’s an acoustasonic Tele that was terrible the first time around, and it’s decidedly not terrible. The Electric XII is back, finally, ~~and it’s even cooler than the Electric Six~~ wait never mind it has a 1 11/16th nut. There is no Tele Plus with a Honda Goldwing emblem, but we make do with what we can. The pyramids are upside-down. Buy a dookie pedal.

How about some synths? Behringer is cranking out another clone, this time an Oberheim OB-Xa. Word on the street is that a 303 is on the horizon, but the vocoder is out now. The Odyssey exists, and the SH-101 clone comes with a handle so you can keytar it. Guitars with Raspberry Pis? Could it be? Yes, Lucern Custom Instruments is collaborating with Tracktion to put a synth in a guitar. There’s a touchscreen BioTek 2 synth installed below the bridge. It’s like something [Matt Bellamy] would play, but it’s got a Raspberry Pi.

Elektron has a new sampler. Oh my god, the only way to make money in the instrument industry is to buy up trademarks. Well, trademarks and signature amps and guitars. Speaking of, where’s the signature Vangelis synths?

The news that will have the biggest impact a decade from now is the announcement that MIDI 2.0 is getting ready for release. New features include auto-config with DAWs, extended resolution, and expressiveness (to stop the Western hegemony on electronic music), and backward compatibility with MIDI 1.0.

This isn’t explicitly NAMM-related, but Eurorack is now a thing and [Jan] is always coming up with some interesting synths-on-a-chip. This time, it’s a drum machine in a Eurorack format. Is it based on anything? Not really, although it would go well in any Detroit acid track. Check out the video.

Let’s say you’re an infosec company, and you want some free press. How would you do that? The answer is Fortnite. Yes, this is how you hack Fortnite. This is how to hack Fortnite. The phrase ‘how to hack Fortnite’ is a very popular search term, and simply by including that phrase into the opening paragraph of this post guarantees more views. This is how you SEO.

Lasers kill cameras. Someone at CES visited the AEye booth, snapped a picture of an autonomous car at AEye’s booth, and the LIDAR killed the sensor. Every subsequent picture had a purple spot in the same place. While we know lasers can kill camera sensors, and this is a great example of that, this does open the door to a few questions: if autonomous cars have LIDAR and are covered in cameras, what’s going to happen to the cameras in an autonomous car driving beside another autonomous car? Has anyone ever seen more than one Cruise or Waymo car in the same place at the same time? As an aside, AEye’s company website’s URL is aeye.ai, nearly beating penisland.net (they sell pens on Pen Island) as the worst company URL ever.

This is something I’ve been saying for years, but now there’s finally a study backing me up. Lego is a viable investment strategy. An economist at Russia’s Higher School of Economics published a study, collecting the initial sale price of Lego sets from 1987 to 2015. These were then compared to sales of full sets on the secondary market. Returns were anywhere between 10 and 20% per year, which is crazy. Smaller sets (up to about 100 pieces) had higher returns than larger sets. This goes against my previous belief that a Hogwarts Castle, Saturn V, and UCS Falcon-heavy portfolio would outperform a portfolio made of cheap Lego sets. However, this observation could be tied to the fact that smaller sets included minifig-only packaging, and we all know the Lego minifig market is a completely different ball of wax. The Darth Revan minifig, sold as an exclusive for $3.99 just a few years ago, now fetches $35 on Bricklink. Further study is needed, specifically to separate the minifig market from the complete set market, but the evidence is coming in: Lego is a viable investment strategy, even when you include the 1-2% yearly cost of storing the sets.

Relativity Space got a launchpad. Relativity Space is an aerospace startup that’s building a rocket capable of lobbing my car into Low Earth Orbit with a methalox engine. They’re doing it with 3D printing. [Bryce Salmi], one of the hardware engineers at Relativity Space, recently gave a talk at the Hackaday Superconference about printing an entire rocket. The design is ambitious, but if there’s one device that’s perfectly suited for 3D printing, it’s a rocket engine. There are a lot of nonmachinable tubes going everywhere in those things.

Hackaday Links: CES Is Over

CES is over, and once again we have proof technology does not improve our lives. Here’s the takeaway from the @internetofshit. There’s a garbage can where you can drop your DNA sample. This is obviously not a Bay Area startup, because they just leave DNA samples on the sidewalk there. The ‘smart cooler’ market is heating up (literally) with a cooler that’s also a grill. Someone duct taped an air filter to a roomba, so your air filter can go to where all the dirty air is in your house. Internet of Rubik’s Cubes. The world’s first autonomous shower made an appearance. Now you can take a shower over the Internet. What a time to be alive.

Need some more bad news from CES? We have more proof the entire tech industry is astonishingly sexist. How so? Well, VR sex simulators can win best of show. That’s a given, obviously. But a ‘smart’ sex toy designed by and for women was selected for a CES 2019 Innovation Award in the Robotics and Drone category. This award was given, then rescinded, by the Consumer Technology Association (CTA) because it was, ‘immoral, obscene, indecent, profane or not in keeping with the CTA’s image’. We presume they mean the latter, but we’re not sure.

Sometimes, though, there are actual engineers behind some of the gadgets on display at CES. Bell (yes, the aerospace company) unveiled the Bell Nexus, a five-seat VTOL ‘taxi’ powered by six ducted fans. These fans are powered by a hybrid electric power system. We assume a turboshaft connected to a generator powering electric motors. Most interestingly, speculation is that this will be the vehicle Uber’s Elevate air taxi program. This initiative by Uber intends to turn a random parking lot in LA into the busiest airport in the world. This is what the official marketing material from Uber says, I am not making this up, and it’s beyond stupid. You know what, just have Uber buy the Santa Monica airport, close it down, and turn it into an air taxi hub. This is the dumbest and funniest possible future imaginable.

Okay, CES is terrible, but here’s something for you. You can get a free ‘maker license’ of Solidworks. Just go here and enter promo code ‘918MAKER’. This info comes from reddit.

The Impossible Project was founded in 2008 as an initiative to remanufacture Polaroid film and refurbish cameras. The project was a rousing success with many supporters. It is a beacon of hope for anyone who wants to keep obsolete formats alive. Now, another format will live on. MacEffects, a company (or eBay store) in Indiana is remanufacturing color ribbons for Apple ImageWriter II printers. The ImageWriter II was the dot-matrix printer in your elementary school’s computer lab if you’re in the Oregon Trail generation, and yes, it could print color pictures. It could print very high-quality color pictures. The problem is getting color ribbons, and now you can get new ones. We’re very interested in seeing the art that can be made with a color ribbon in an ImageWriter, so if you have a portfolio, send it on in. If you have an ImageWriter, try to print something. It’s a serial printer, not a parallel printer.

The entirety of Silicon Valley is predicated on the ability to ‘move fast and break laws’. Have an idea for a scooter startup? No problem, just throw a bunch of scooters on the curb, littering and e-waste laws be damned. Earlier this year, Swarm Technologies launched four rogue satellites on an Indian rocket. All commercial satellite launches by US companies are regulated by the FCC, and Swarm just decided not to tell the FCC. This was the first unauthorized satellite launch ever. Now, Swarm has been fined $900k. Now that we know the cost of launching unauthorized satellites, so if you’ve got a plan for a satellite startup, the cost for an unauthorized launch is a bit more than $200k per satellite. Be sure to put that in your budget.

Santa Claws! Liberty Games would like to donate to a charity this holiday season, but you can’t just write a check. That’s not fun. Instead, they connected a claw machine to the Internet, and anyone can play it. Setting up a webcam was easy enough, but they also had to move the claw and press the button over the Internet. A Raspberry Pi came to the rescue.

Tomorrow is the 50th anniversary of Apollo 8, mankind’s first trip beyond Earth orbit. Now, using Lunar Reconnaissance Orbiter data, NASA has reconstructed the famous ‘Earthrise’ photo taken by the crew. It’s in 4K, and we’re getting a great diagram of what pictures were taken when, through which window.

It’s that time of year again, and the 176th Air Defense Squadron is on high alert. This squadron, based out of Joint Base Elmendorf-Richardson in Anchorage, Alaska has the AWACS in the air, on patrol, just waiting for the inevitable. You can take a look at their progress here, and please be sure to keep our service members in your thoughts this holiday season.

SpaceX launched a rocket this week, and things did not go as planned. The hydraulics on the grid fins were stuck when the first stage started its atmospheric recovery, and the booster became a fish. The booster landed about a mile or so offshore, which meant we got some great footage of a failed landing, and there are even better shots of the guts of a landed booster. [Scott Manley] whipped out a video showing the ‘new’ discoveries of what’s going on inside a Falcon 9 booster. Interestingly: the weight of the upper stage is carried through the thrust plate of its engine (which makes sense…). There’s a lot of pneumatic stuff going on, and while the composite interstage is very strong along the long axis of the rocket, it doesn’t like being slammed into the ocean.

Winter is coming, and that means you should take your car out during the first snow, drive out to an empty parking lot, and do donuts. I am not kidding this is how you learn to drive in the snow. How do they do it in Russia? They weld 3000 nails to a steel wheel. Does it work? For a while, then the nails bend. We’ve seen this done by drilling screws through a tire, and that works much better; it’s less length for the screws to fulcrum over.

Aaay, we got a date for Sparklecon! It’s February 1-3rd in the endless suburban wastes of Fullerton, California. It’s in an industrial park, there’s a liquor store around the corner, and there’s a remote-controlled couch. Get on it.

Just enter your friend’s shipping address during checkout, and the extra-special scorpion supply chain management will mean your scorpions are delivered fast to their door.

Regular Car Reviews finally reviewed a Pontiac Aztek. The takeaway is that it’s a bug-out car for Boomers, designed in that episode of The Simpsons where Homer finds out he has a brother.

Want to see something weird? It’s a G3 iMac running Windows 8. This is… weird. Either someone is doing a remote desktop into a Windows 8 machine, someone is just using screenshots, or this machine is way cooler than the craigslist seller is letting on. If you’re in Dallas, it might be worth picking this up.

CircuitPython is becoming a thing! CircuitPython was originally developed from MicroPython and ported to various ARM boards by Adafruit. Now, SparkFun is shipping their own CircuitPython board based on the nRF52840, giving this board an ARM Cortex-M4 and a Bluetooth radio.

You like contests, right? You like circuit boards too, right? Hackster.io now has a BadgeLove contest going on to create the Blinkiest Badge on Earth. Yes, this is a #badgelife contest, with the goal of demonstrating how much you can do in a single circuit badge. Prizes include a trip to San Francisco, a badass drone, a skateboard, a t-shirt, or socks. YES, THERE ARE SOCKS.

We have a date for the Vintage Computer Festival Pacific Northwest 2019. It’s going down March 23 and 24 at the Living Computers Museum in Seattle. The call for exhibitors is now open so head over and check it out. So far the tentative list of exhibits and presenters include Attack of the SPARC Clones, and I must mention that SPARC systems are showing up on eBay with much higher frequency lately. I have no idea why.

Need another con? How about a KiCAD con? The inaugural conference for KiCAD users is happening next April in Chicago and the call for talk proposals just opened up. The con focuses on topics like using KiCAD in a manufacturing setting, what’s going on ‘under the hood’ of KiCAD, and how to use KiCAD to make an advanced product.

Spanish police have stopped a homemade scooter. Someone, apparently, was tearing around a public road in Galacia on a homemade scooter. From the single picture, we’re going to say ‘not bad.’ It’s a gas-powered weed wacker mounted to a homemade frame.

Every year, in December, we take a look back at what Hackaday has accomplished in the past twelve months. Sure, we gave out hundreds of thousands of dollars in awards in the Hackaday Prize, and yes, we’ve pushed our coverage of tech advancements into weird, uncharted, but awesome territory. Our biggest accomplishment, though, is always how many readers we reach. This year, we had a slight fall-off in our readership in the Democratic People’s Republic of North Korea. We’re down from 156 views in 2017 to 75 views this year. While the year isn’t over, we don’t expect that number to change much. What was the cause of this drop-off? We’re not quite sure. Only time will tell, and we’re looking forward to serving fresh hacks every day to the DPRK in 2019.
