Lying somewhere between the roboflusher and LEGO car-producing LEGO factory on the practicality scale, José Pino's Mindstorms NXT gramophone brings together all the fun and tinny sound of this antiquated music system with today's modern DIY sensibilities. Using little more than an off-the-shelf NXT kit running at 25% power, and, um, a fast food beverage cup, Pino was able rig together a very basic platform for spinning his vinyl, although scratching is probably not recommended on this rather delicate setup. Keep reading for a quick video walkthrough accompanied by those old-timey tunes so popular among today's seniors.

It's not always a question of why -- sometimes why not will suffice. The rolling bot above relies upon the Mindstorms NXT light sensor's ability to read the contrasting colors on the iPhone display. After some simple programming and DIY tomfoolery you can drive the robot from the comforts of your WiFi-enabled web browser. Overkill? Oh hells yeah, but at least now your iPhone will serve a purpose after Monday. See how the kids at Battlebricks did it in the video after the break.

LEGO Mindstorms ready for Tuesday space launch

To celebrate the 10th anniversary of LEGO Mindstorms, a group of professors, middle-school students, and corporate nerds will be launching several Mindstorms robots into near-space. The High Altitude LEGO Extravaganza (HALE) project will set the robots aloft in an atmospheric weather balloon shortly before sunrise this morning outside of Reno, Nevada. At about 100,000 feet (30km) the balloon will burst and the robots will parachute back to terra firma collecting data and photographs along the way. One robot named Lil' Joe will attempt a world record free-fall decent before deploying its parachute on a pre-programmed schedule. Mind you, the world record is attributable to Mindstorms NXT free-fall, a title we expect is currently held by your little brother sleeping upstairs.

No, your eyes don't deceive: it's a Lego safe. Apparently Lego's computer-equipped Mindstorms NXT can be used for something more practical than launching robots into space (great as that was), and believe it or not, this box is actually kind of secure. Five double digit codes protect your valuables, and the dial goes both ways, so there's a left and right entry for each number -- hence, over 305 billion possible combinations. Moving the safe will trip motion sensors and set off an alarm, and bars inside strengthen the structure, so while master diamond thieves won't be deterred, surreptitious little siblings might. Video after the break, and check the right nav through the read link to dig up building instructions.

We've seen some pretty kick-ass Lego creations over the years, and this one is no exception -- if anything, it gets bonus points for not only being a pretty sweet hack, but for enabling sweeter, more complex, hacks in the future. The 3D scanner was built by Philo Hurbain, who was looking for a way to model complex Lego parts for use in the LDraw CAD program. This bad boy -- including drive components and sensors -- is entirely made from the colorful plastic toy, except for the probe needle (an old school sewing needle, apparently). The "brain" of this thing is Mindstorms NXT. But that ain't all! Check out the device in action as it models a tiny Lego frog -- video after the break.

Not wanting the Allspark to beat them to the punch, the gang at thinkingbricks has given life to an Apple G4 Cube, complete with LEGO Mindstorms NXT-borne retractable wheels, a Bluetooth controller, automation via sensors, and a creepy red LED. That transparent base really makes the wheel deployment much more dramatic, a nice touch if we do say so ourselves. There aren't any step-by-step instructions, but there should be plenty of information at the page if you're thiking of making your own as a weekend project. Either way, be sure to check it out on video, located after the break.

Oh sure, you've seen your disgustingly hairy cousin solve a Rubik's Cube in 3 minutes and 13.4 seconds, and we've seen quite a few sophisticated robots do it in far less time. But in the latest episode of "Yes, Droid Really Does," we've got Motorola's darling solving a Lego-encased Cube in just over 24 seconds. Let's recap: a Droid, a Mindstorms NXT monstrosity, a Rubik's Cube and faux techno. Is there any chance you aren't clicking through to watch this video?

Update: Whoops -- had the wrong image in there somehow. Fixed now!

We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget question is coming to us from Ryan, who reckons it's about time he stopped playing with Lego blocks and began playing with a real man's robot platform. Just kidding about the Lego bit. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com.
"I am an aspiring roboticist who has been using Lego Mindstorms NXT for a few years and I am looking for the next step up. I have a budget of about $400. I am looking for something that has more motors, more sensors, and a way to have it live feed video back to a computer. I would also like a platform that has a large amount of building that can be done on top of it, such as adding an arm or another array of sensors, or a different drive base. I'm new to the world of robotics outside of the NXT, so any tips would be appreciated as well. Thanks!"
Come on over, robot lovers. Toss those gloves and goggles aside for a moment and throw this guy some advice. What platform keeps you up in the garage at night?

Lego bipedal bot takes several small stairs for man, one big fall for robotkind (video)

Climbing stairs is one of the hardest physical tasks for a bipedal collection of motors and circuits, as Honda's ASIMO can relate, but one man's managed to achieve just that with this head-banging Lego Mindstorms NXT robot. After spending years tinkering with the plastic blocks, 222Doc's X-2 Chicken Walking Biped can autonomously walk up and down flights of small steps with relative ease, perform headstands and even scale five-inch cinder block cliffs if precariously pushed. The robot requires only seven Lego servo motors plus a touch sensor and gyroscope in each foot, but also uses a pair of third-party multiplexers (also spotted in that transforming Wall-E) for fine control of the extra motors. Watch it perform after the break, but stop the second video at 3:20 if pain makes you queasy -- the bot takes a pretty ugly spill.

When society collapses and the national energy infrastructure goes to pot, at least you'll still be able to run your fantastical Lego Mindstorms NXT creations. That's right: the fine folks at Dexter Industries are offering panels, batteries, and all the geegaws necessary to power your projects the old fashioned way: with the sun. The basic dSolar 2W System ($90) features a 9 volt solar panel with enough juice to power the NXt and a single motor in direct sunlight (about 250 mA). There is also a four watt system available for $100, as well as capacitor banks, parallel connectors for multiple panels, and more. Hit up the source link to get started -- but not before you check out the video after the break.

Just because the first few tablet textbooks have shipped doesn't mean that members of Kno's development team are resting on their laurels. Product testing on the Kno tablet continues -- and it looks like Lego is doing the heavy lifting. They've put our favorite plastic building blocks to work by constructing a Kno stress tester out of Lego Technic parts. The robot checks both the Kno's ambient light sensor and the ability of its touchscreen to accurately track the system's pen swipes and flicks. Though not as intricate as a Lego replica of a 2000+ year old mechanical computer, the robot -- with its hypnotic pendulum-like motion -- is still a sight to behold. Check the video after the break.

NXTBee enables long-distance wireless for Mindstorms NXT, funny little RC cars (video)
Lego Mindstorms NXT is robotic democratization, DIY designing for the everyman, but being stuck with only Bluetooth or IR wireless can put a bit of a damper on your egalitarian goals. No more. Dexter industries (who previously brought us solar-powered Mindstorms) has created the NXTBee, which uses the an Xbee radio to send data much further: 300 feet for the base $55 NXTBee, up to a mile if you opt for the $78 NXTBee-PRO. You'll probably need two of the things, though, so make sure you budget appropriately. There's definitely some lag evident in the video of a long-range RC car below, but we're not sure if that's the wireless or the machine itself. Regardless, that's surely a design challenge that won't stop you from having fun with this one.

If this image doesn't have you completely dumbfounded, scroll down and watch the video. Sufficiently awestruck? Good. Now, for a little background on exactly how someone got a pile of Legos and a smartphone to solve the devil's puzzle Megaminx. The aptly titled Megaminxer enlists the Mindstorms NXT kit to do the dirty work and an HTC Desire, running a custom Android app, as the brains of the operation. Said app uses the phone's camera to take individual images of each of the puzzle's 12 faces, then processes the information and sends a signal via Bluetooth to the NXT controller, which in turn goes to town. Unfortunately, there's no explaining how they got the Android to dance like that, but, really, why ruin the magic?

If you build it, they will come; so the saying goes. And robotics-loving Mindstorms NXT-enthusiast Leon built it. What exactly? Well, a car. But not just any old brick-mobile, one you -- yes you -- at home can control via Skype. How does one conjure up such sorcery? By training a light sensor on a laptop screen, for receiving Skype calls, a soupçon of screen sharing, all mixed with a little web code so you can pilot remotely. The final lap is over a Bluetooth connection, plus there's a clever self-charging system originally featured on these very pages. Fancy taking it for a spin? You've got until the 18th of this month before Leon gets fed-up with the constant reverse donuts. Check the video after the break to see the truly "remote controlled" car in action, and tap the source to see how you too can take it for a spin.

Flying Fortress Lego blimp lords over us with a Mindstormsbased iron fist video

Most Lego Mindstorms constructions have never slipped the surly bonds of Earth. The Flying Fortress Lego Blimp from Tyler Westmoreland and Chris Shepard won't be similarly held down, however. Courtesy of two NXTBee wireless adapters, Tyler and Chris can fly the Mindstorms NXT-driven airship using a remote control and adjustable propellers. There's no secret tricks involved, as everything is an off-the-shelf part that anyone can find, including the 55-inch helium balloons. We have proof: Tyler has shared the source code for both the blimp and the controller, so anyone with the resources can recreate the Flying Fortress for themselves. While the thought of homemade drone blimps looming overhead is slightly disconcerting, we'll steel our resolve when it means that most any enterprising builder can take Lego airborne.

Facebook is coming back online after hours-long outage

$

Facebook services are slowly coming back online after one of the biggest outages in recent memory. Facebook, Instagram, WhatsApp and Messenger’s apps appear to be working again, though some of the websites are loading more slowly than usual. 

As of 6:05pm ET Monday, the "Facebook for Business Status" page was still showing "major disruptions," to the social network's core services. But that was still an improvement from earlier in the day when the website was offline entirely. 

"To the huge community of people and businesses around the world who depend on us: we're sorry," Facebook wrote in a statement posted to Twitter. The company confirmed its services "are coming back online now." In a post on Facebook, CEO Mark Zuckerberg also apologized for the services going down. 

Zuckerberg didn’t elaborate on the cause of the lengthy outage. In an earlier tweet, the company’s outgoing Chief Technology Officer, Michael Schroepfer, cited “networking issues.”

The outage lasted more than six hours, taking down Instagram, WhatsApp, Messenger and Oculus. It also wreaked havoc on the company internally, with employees reportedly unable to access emails, Workplace and other tools. The New York Timesreported that employees were also physically locked out of offices as workers’ badges stopped working.

It also shaved billions of dollars off of Zuckerberg’s personal net worth as Facebook’s stock tanked, Bloomberg reported. Elsewhere, the company is still reeling from the fallout of a whistleblower who has accused the company of prioritizing “profits over safety.” The whistleblower was The Wall Street Journal’s primary source for several articles that details how Instagram is harmful to teens and the company’s controversial “cross check” program that allows high profile users to break its rules.

Security reporter Brian Krebs reported the outage was linked to issues with Facebook's BGP (Border Gateway Protocol) records, which prevented the company's services from being accessible. He later added it was "a routine BGP update gone wrong." DNS provider Cloudflare also cited BGP as the likely culprit, writing in a blog post that it was "as if someone had 'pulled the cables' from their data centers all at once and disconnected them from the Internet." 

Late into Monday evening, Facebook's engineering team published a blog post that attempted to explain what happened: 

"Our engineering teams have learned that configuration changes on the backbone routers that coordinate network traffic between our data centers caused issues that interrupted this communication. This disruption to network traffic had a cascading effect on the way our data centers communicate, bringing our services to a halt."

It went on to say that the root cause of the outage was a "faulty configuration change" and there's no evidence that user data was compromised due to the downtime.  

Update 10:30PM ET: Added a statement from Facebook Engineering's blog post. 

Tesla must pay $137 million in discrimination lawsuit

Tesla has been ordered to pay $137 million in damages to a former Black worker who accused the company of turning a blind eye to discrimination and racial abuse at the company's EV plant in Fremont California, The Washington Post has reported. A San Francisco federal court jury awarded the judgement — reportedly one of the largest in an individual race discrimination employment case — to Owen Diaz, an elevator operator who worked as a contract employee in 2015 and 2016.

In the lawsuit, Diaz alleged that he faced discrimination "straight from the Jim Crow era," in which he was subjected to racial slurs. He alleged that Tesla employees left drawings of swastikas, racist graffiti and offensive cartoons around the plant, while supervisors neglected to halt the abuse. "Tesla's progressive image was a façade papering over its regressive, demeaning treatment of African-American employees," according to the lawsuit. 

The jury awarded Diaz $6.9 million for emotional distress, but the majority, $130 million, was punitive damages against Tesla. "It's a great thing when one of the richest corporations in America has to have a reckoning of the abhorrent conditions at its factory for Black people," said the lawyer for Diaz, Lawrence Organ. 

"It took four long years to get to this point,” Diaz told The New York Times. “It’s like a big weight has been pulled off my shoulders.”

In response to the verdict, Tesla downplayed the allegations in a blog post written by human resources VP Valerie Capers Workman. "In addition to Mr. Diaz, three other witnesses (all non-Tesla contract employees) testified at trial that they regularly heard racial slurs (including the N-word) on the Fremont factory floor,” she wrote. “While they all agreed that the use of the N-word was not appropriate in the workplace, they also agreed that most of the time they thought the language was used in a ‘friendly’ manner and usually by African-American colleagues.”

Tesla added that it was responsive to Mr. Diaz's complaints, firing two contractors and suspending another. She said that while the facts didn't justify the verdict, the company was "not perfect" in 2015 and 2016, "but we have come a long way." The company has yet to say whether it plans to appeal.

The Apple TV 4K 32GB drops to $159 at Adorama

The 2021 Apple TV 4K saw major improvements over the previous model, especially with performance and the improved Siri remote. However, it's still pretty expensive for a set-top streaming device with a starting price of $179. If you've been waiting for a sale to pick one up, you can now save $20 on the 32GB model and buy one for just $159 at Adorama — one of the better prices we've seen. 

Buy Apple TV 4K 32GB at Adorama - $159

With a review score of 90, the 2021 Apple TV 4K is among the best high-end streaming boxes available, particularly for Apple users. The A12 Bionic processor delivers zippy performance, and it supports Dolby Vision at 60 fps and Dolby Atmos sound, along with AirPlay 3 and screen mirroring. It also supports HomeKit, letting you ask Siri to show you video feeds, control smart lights, locks and more.

The key difference with the last model, however, is the redesigned Siri remote. It's not only larger and easier to use, but also touch sensitive so you can swipe between options more easily. Best of all, Apple's sometimes-maligned Siri voice assistant works well with Apple TV, easily handling commands like "Play Ted Lasso" or "Show me some new comedy films." 

The primary downside, as mentioned, is the price. Roku's Ultra is only $100 (and often less on sale), while Google's Chromecast with Google TV, which finally comes with a remote, is $50. However, Apple TV 4K is loaded with nice features, especially for folks in Apple's ecosystem, and today's sale makes it a lot more affordable.
