WeWork's Former CEO Has a New Startup, Reportedly Valued At More Than $1 Billion (cnn.com) 64

Nearly three years after Adam Neumann stepped down as CEO of WeWork following a failed attempt to take the company public, he is said to once again be in charge of a billion-dollar real estate startup. CNN Business reports: Andreessen Horowitz, the prominent venture capital firm known for its early investments in Twitter and Airbnb, has pumped about $350 million into Neumann's newest venture, called Flow, according to The New York Times, citing unnamed sources briefed on the deal. The investment valued the startup at more than $1 billion, according to the report. In a blog post Monday, Marc Andreessen, cofounder and general partner at the VC firm, announced the investment, without disclosing financial details. He also explained his thinking for backing Flow, a residential real estate company, and Neumann despite the founder's high-profile fall from grace at WeWork.

"Adam is a visionary leader who revolutionized the second largest asset class in the world -- commercial real estate -- by bringing community and brand to an industry in which neither existed before," Andreessen wrote in his post Monday. "Adam, and the story of WeWork, have been exhaustively chronicled, analyzed, and fictionalized -- sometimes accurately. For all the energy put into covering the story, it's often under appreciated that only one person has fundamentally redesigned the office experience and led a paradigm-changing global company in the process: Adam Neumann." It's not immediately clear how Flow seeks to revolutionize the residential housing industry. Flow currently has a bare bones website, with the slogan "Live life in flow" and two words stating it will launch in 2023.

Andreessen positioned the new company as a long-awaited solution to the nation's "housing crisis." He used a mix of jargon-filled terms -- "community-driven, experience-centric service" -- to explain how the new startup would "create a system where renters receive the benefits of owners." "We think it is natural that for his first venture since WeWork, Adam returns to the theme of connecting people through transforming their physical spaces and building communities where people spend the most time: their homes," Andreessen wrote. "Residential real estate -- the world's largest asset class -- is ready for exactly this change."

Russian Army Expo Shows Off Robot Dog Carrying Rocket Launcher (pcmag.com) 56

At a military convention in Russia, a local company is showing off a robot dog that's carrying a rocket launcher. From a report: Russian news agency RIA Novosti today filmed the four-legged bot at the Army 2022 convention, which is taking place near Moscow and sponsored by the country's Ministry of Defense. The robot was recorded trotting along on the convention floor while wielding a rocket-propelled grenade launcher on its back. The robot is also capable of crouching on the floor, making it harder to spot, while it presumably waits to fire off a rocket. It remains unclear if the robot will ever be used on the field when Russia is locked in a war with Ukraine, and already using air-based drones at least for recon and targeting purposes. But according to RIA Novosti, the bot is dubbed the M-81 system and comes from a Russian engineering company called "Intellect Machine." The developers say the robot dog is being designed to both transport weapons and ammunition and fire them during combat missions.

Right To Repair Battle Heats Up With Rooting of John Deere Equipment (wired.com) 79

Long-time Slashdot reader drinkypoo writes: John Deere, current and historic American producer of farming equipment, has long been maligned for their DRM-based lockdowns of said equipment which can make it impossible for farmers to perform their own service. Now a new security bypass has been discovered for some of their equipment, which has revealed that it is in general based on outdated versions of Linux and Windows CE.

Carried out by Sick Codes, the complete attack involves attaching hardware to the PCB inside a touchscreen controller, and ultimately produces a root terminal.

In the bargain and as a result, the question is being raised about JD's GPL compliance.

Sick Codes isn't sure how John Deere can eliminate this vulnerability (beyond overhauling designs to add full disk encryption to future models). But Wired also notes that "At the same time, though, vulnerabilities like the ones that Sick Codes found help farmers do what they need to do with their own equipment."

Although the first thing Sick Codes did was get the tractor running a farm-themed version of Doom.

Cellphone at Third Base: Baseball Player Mistakenly Runs the Bases with His iPhone (apnews.com) 38

Last year Rodolfo Castro made baseball history. Called up to the Major Leagues in April, the 22-year-old eventually recorded his first hit — a home run. But his next four recorded hits were all also home runs, something no player had done since 1901.

CBS News reports that this week, finally called back up to the Major Leagues, Castro again made history — of another sort: Modern technology has allowed people to take their phones, as well as the power of the internet, with them anywhere they go. Pittsburgh Pirates second baseman Rodolfo Castro took his around the bases against the Arizona Diamondbacks on Tuesday night.
Yep — an iPhone made a bizarre cameo in the 4th inning, reports the Associated Press: Castro and third base coach Mike Rabelo stood and stared, mortified.... Even third base umpire Adam Hamari had the perfect reaction, pointing at the phone that came flying out of Castro's back pocket during a head-first slide, trying not to giggle at the absurdity of the situation.

Those around the sport cringed along with them. "That's obviously not something that should happen," Yankees manager Aaron Boone said.... This faux pas just happened to be at a televised big league game, creating a video clip seen by millions.

"I just remember getting dressed, putting my pants on, getting something to eat, using the restroom," the 23-year-old Castro said through a translator Tuesday night after the Pirates lost 6-4 to Arizona. "Never did it ever cross my mind that I still had my cellphone on me...."

It's far from the first time a phone has made a cameo on a pro sports field. One of the most famous examples came nearly 20 years ago when New Orleans Saints receiver Joe Horn pulled out a flip phone — remember those? — that he had hidden in the padding around the goalpost and then acted like he was taking a call after scoring a touchdown.

Gen Z is Over Facebook, Finds Pew Research. But YouTube Dominates Among Teens (nbcnews.com) 57

NBC News reports: Facebook, once the go-to social media platform for many, has plummeted in popularity among younger users, according to a new Pew Research Center survey.... The share of 13- to 17-year-olds who said they use Facebook dropped from 71% in the 2015 study to 32% today, Pew found.

As Facebook's popularity sinks, YouTube has become the dominating platform among teens, who are also using social media apps like TikTok, Snapchat and [Meta-owned] Instagram... While Facebook still beats out Twitter among Gen Z teens, Snapchat and Instagram have dwarfed its popularity. Sixty-two percent of teens use Instagram and 59% use Snapchat, according to Pew. TikTok also beats Facebook in popularity, with 67% of respondents saying they use the short-form video app, Pew reported....

The most popular platform among 13- to 17-year-olds is YouTube, which is used by 95% of teens, the research found.

There's an interesting graph showing trends in Pew's announcement. It's handy way to visualize that over the last seven years usage has dropped for Facebook, Twitter, and Tumbler — while usage increased for Instagram and Snapchat.

But YouTube hovers above them all with 95% usage.

Are Things 'Looking Grim' For Movies Based on DC Superheroes? (theverge.com) 117

"The fate of Warner Bros. DC Comics movies is looking grim," writes the Verge.

Since April's merger between Warner Brothers and Discovery, they call it "fairly obvious" that "the new guard at Warner Bros. Discovery wants to jettison or at the very least put some distance between itself and the DC Extended Universe's current iteration (along with all the baggage associated with the endeavor.)" The DC Extended Universe was plagued by a number of issues long... like a general lack of cohesion, subpar storytelling, and an association with a toxic fandom whose obsession eventually devolved into harassment campaigns against studio executives. Looking back, Justice League as it was released in 2017 was a haphazard attempt to catch up to the Marvel Cinematic Universe that put far too much faith in the power of people's general familiarity with characters like Wonder Woman, Cyborg, and Aquaman who didn't really have presences in the DC Extended Universe at the time.
Screen Rant calls Justice League "a movie that polarized audiences and was less successful than Man of Steel at the box office" — then explains what happened next: The DC Extended Universe had been struggling with highly divisive or critically panned movies, such as Batman v Superman: Dawn of Justice and Suicide Squad, but it was not until Justice League that the franchise really took a significant financial hit. In addition, Justice League was also the start of a series of behind-the-scenes controversies, and at this point, it is difficult to picture the Justice League cast all returning for a sequel....

With Ben Affleck seemly done with Batman and the studio wanting to move away from everything Justice League-related, DC needed a way to combine what had been working, such as Jason Momoa's Aquaman and Gal Gadot's Wonder Woman, with new strategies, such as Michael Keaton's [appearing in the upcoming Flash movie as] Batman. The answer seemed simple — the multiverse....

The fact that Batgirl, a movie that would have shown the aftermath of The Flash's multiverse journey, was canceled [last week] proves that the multiverse is no longer a priority for DC. Not only that but right before Batgirl's cancelation was announced, it was reported that Ben Affleck would replace Michael Keaton's rumored cameo in Aquaman and the Lost Kingdom.... During Warner Bros. Discovery's earning calls on August 5, CEO David Zaslav mentioned that the new management will make upcoming DC Extended Universe movies like Black Adam and The Flash "even better", suggesting that reshoots could be on the way.

VLC Media Player Banned In India (indiatoday.in) 40

One of the most popular media player software and streaming media server VLC media player, developed by VideoLAN project, is no longer working in India. India Today reports: As per a report by MediaNama, VLC Media Player has been blocked in India nearly 2 months ago. Neither the company nor the Indian government has revealed any details about the ban. Some reports suggest that VLC Media Player has been blocked in the country because the platform was China-backed hacking group Cicada was using it for cyber attacks. Just a few months ago, security experts discovered that Cicada was using VLC Media Player to deploy a malicious malware loader as part of a long-running cyber attack campaign.

Since it was a soft ban, neither the company, nor the Indian government officially announced the banning of the media platform. Some users on Twitter are still discovering the restrictions of the platform. One of the Twitter users by the name Gagandeep Sapra tweeted a screenshot of the VLC website that shows âoethe website has been blocked as per order Ministry of Electronics and Information Technology under IT Act, 2000." Currently, the VLC Media Player website and download link are blocked in the country. In simple words, this means that no one in the country can access the platform for any work. This is seemingly the case for users who have the software installed on their device. It is said that VLC Media Player is blocked on all major ISPs including ACTFibernet, Jio, Vodafone-idea and others.

Bricked Epson Printers Make a Strong Case For User Repairability (theverge.com) 101

Epson has gained some scrutiny in recent weeks after the company disabled a printer that was otherwise working fine, leading to accusations of planned obsolescence. Epson knows its printers will stop working without simple maintenance at a predictable point in the future, and it knows that it won't be cost-effective for many owners to send their home printers in for service. So why not build them to be user serviceable in the first place? The Verge: The inciting post from @marktavern mentions that his wife was unable to use her "very expensive Epson printer" after an end-of-service error message appeared. This isn't anything new for Epson printers, sadly. Reports going back several years mention an infamous error message that reads "parts inside the printer have reached the end of their service life." Epson confirmed to The Verge that the error is related to the printer's ink pads, which had likely become saturated through extended use and were now at risk of spilling into the rest of the printer mechanism.

In a recently updated support document, Epson offers several solutions to resolve the problem. These include sending the printer into Epson to replace the ink pads or having a local certified technician do it. Previously (via Wayback Machine), just before the issue gained notoriety, Epson conceded that "repair may not be a good investment for lower cost printers because the printer's other components also may be near the end of usable life." It then added that "most consumers who are out of warranty elect to replace a lower-cost printer when they receive an end of life service message." Now, Epson suggests the feel-good option of sending the bricked unit in for recycling.

Cisco Hacked By Yanluowang Ransomware Gang, 2.8GB Allegedly Stolen (bleepingcomputer.com) 21

An anonymous reader quotes a report from BleepingComputer: Cisco confirmed today that the Yanluowang ransomware group breached its corporate network in late May and that the actor tried to extort them under the threat of leaking stolen files online. The company revealed that the attackers could only harvest and steal non-sensitive data from a Box folder linked to a compromised employee's account. "Cisco experienced a security incident on our corporate network in late May 2022, and we immediately took action to contain and eradicate the bad actors," a Cisco spokesperson told BleepingComputer. "Cisco did not identify any impact to our business as a result of this incident, including Cisco products or services, sensitive customer data or sensitive employee information, intellectual property, or supply chain operations. On August 10 the bad actors published a list of files from this security incident to the dark web. We have also implemented additional measures to safeguard our systems and are sharing technical details to help protect the wider security community."

The Yanluowang threat actors gained access to Cisco's network using an employee's stolen credentials after hijacking the employee's personal Google account containing credentials synced from their browser. The attacker convinced the Cisco employee to accept multi-factor authentication (MFA) push notifications through MFA fatigue and a series of sophisticated voice phishing attacks initiated by the Yanluowang gang that impersonated trusted support organizations. The threat actors finally tricked the victim into accepting one of the MFA notifications and gained access to the VPN in the context of the targeted user. Once they gained a foothold on the company's corporate network, Yanluowang operators spread laterally to Citrix servers and domain controllers.

"They moved into the Citrix environment, compromising a series of Citrix servers and eventually obtained privileged access to domain controllers," Cisco Talos said. After gaining domain admin, they used enumeration tools like ntdsutil, adfind, and secretsdump to collect more information and installed a series of payloads onto compromised systems, including a backdoor. Ultimately, Cisco detected and evicted them from its environment, but they continued trying to regain access over the following weeks. [...] Last week, the threat actor behind the Cisco hack emailed BleepingComputer a directory listing of files allegedly stolen during the attack. The threat actor claimed to have stolen 2.75GB of data, consisting of approximately 3,100 files. Many of these files are non-disclosure agreements, data dumps, and engineering drawings.

Iran Cheerfully Admits Using Cryptocurrency To Pay For Imports (theregister.com) 65

Iran has announced it used cryptocurrency to pay for imports, raising the prospect that the nation is using digital assets to evade sanctions. The Register reports: Trade minister Alireza Peyman Pak revealed the transaction with the tweet [here], which translates as "This week, the first official import order was successfully placed with cryptocurrency worth ten million dollars. By the end of September, the use of cryptocurrencies and smart contracts will be widespread in foreign trade with target countries."

It is unclear what Peman Pak referred to with his mention of widespread use of crypto for foreign trade, and the identity of the foreign countries he mentioned is also obscure. But the intent of the announcement appears clear: Iran will use cryptocurrency to settle cross-border trades.

A Fifth of US Teens Use YouTube 'Almost Constantly,' With TikTok Not Far Behind (engadget.com) 50

Pew Research has published a new report that examines social media usage trends among US teens. The organization found that a whopping 95 percent of them use YouTube, while 19 percent are on the platform "almost constantly." Engadget reports: Perhaps unsurprisingly, two-thirds (67 percent) said they used TikTok, with 16 percent claiming they are on the app "almost constantly." The third most-popular social media platform among teens is Instagram, per Pew, with 62 percent using it. A tenth say they use it almost all the time -- despite the app occasionally telling them to take a break. A previous poll conducted in 2014-15 found that 52 percent were using Instagram (Pew didn't ask about YouTube usage for that survey and TikTok didn't exist at the time).

Snapchat also rose among teens, with 59 percent using it in 2022, compared with 41 percent in the previous poll. Facebook was the top social media app among teens seven years ago, with 71 percent of them using it, but that figure has dropped to 32 percent. Teen adoption of Twitter (down from 33 percent to 23 percent) and Tumblr (14 percent to five percent) has fallen over the same period too. The 2014-15 poll didn't ask about Twitch, WhatsApp or Reddit. These days, a fifth of teens use Twitch, 17 percent are on WhatsApp and 14 percent are accessing Reddit.

28 Years Later, Super Punch-Out!!'s 2-Player Mode Has Been Discovered (arstechnica.com) 25

Hmmmmmm shares a report from Ars Technica: While Punch-Out!! has been one of Nintendo's most beloved "fighting" series since its 1984 debut in arcades, it has rarely featured something common in the genre: a two-player mode. On Monday, however, that changed. The resulting discovery has been hiding in plain sight on the series' Super Nintendo edition for nearly 30 years. Should you own 1994's Super Punch-Out!! in any capacity -- an original SNES cartridge, a dumped ROM parsed by an emulator, on the Super Nintendo Classic Edition, or even as part of the paid Nintendo Switch Online collection of retro games -- you can immediately access the feature, no hacking or ROM editing required. All you need is a pair of gamepads.

[T]oday's Super Punch-Out!! discovery revolves around a simple series of button combinations, which require nothing more than a second controller. The two-player mode is hidden behind an additional, previously undiscovered menu, which lets solo players skip directly to any of the game's boxing combatants. It's essentially a "level select" menu, which many classic games featured for internal testing, and speedrunners could arguably use it to practice against specific opponents more quickly.

This menu can be accessed by holding the R and Y buttons on player two's controller at the "press start" screen, then pressing Start or A with player one's controller. Do this, and a new menu appears, displaying all 16 boxers' profile icons. Pick any of these icons to engage in a one-off fight; once it's over, you're dumped back to the same boxer-select menu. In this menu, friends can access a two-player fight if player two holds their B and Y buttons down until the match starts. You won't hear a sound effect or any other indication that it worked. Instead, the match will begin with the second player controlling the "boss" boxer at the top of the screen. Combine the "ABXY" array of buttons with "up" and "down" on the D-pad to pull off every single basic and advanced attack.

Burger King Blank Email Orders Confuse Thousands of Customers (theverge.com) 38

Burger King has just emailed thousands of customers with a blank order email receipt. The Verge reports: The blank emails started appearing at around 12:15AM ET, leaving Burger King customers confused whether the company has been breached by a hungry hacker attempting a midnight feast, or if the emails are simply a giant whopper of a mistake. Twitter users were quick to turn to the social network in a state of confusion over the blank emails, with some even receiving two Burger King emails in an apparent double whopper of a mistake. The order emails are totally blank, and were sent by Burger King's main promotional marketing email address.

After this story was published, an email from "BK PR Team" responded to our request for more information, claiming the issue was "the result of an internal processing error." We have asked for a specific individual to attribute the information to.

Curve Finance Front End UI Compromised In DNS Hack (cointelegraph.com) 12

According to researcher samczsun at Paradigm, Curve Finance has had its front end compromised, with over $500K stolen within a matter of minutes. The automated market maker is warning users to exercise caution when interacting with the site. Binance CEO Changpeng Zhao also shared the news and is monitoring the situation. CoinTelegraph reports: Curve stated via Twitter that its exchange -- which is a separate product -- appeared to be unaffected by the attack, as it uses a different DNS provider. Twitter user LefterisJP speculated that the alleged attacker had likely utilized DNS spoofing to execute the exploit on the service: "It's DNS spoofing. Cloned the site, made the DNS point to their ip where the cloned site is deployed and added approval requests to a malicious contract."

Other participants in the DeFi space quickly took to Twitter to spread the warning to their own followers, with some noting that the alleged thief appears to have stolen more than $573K USD at time of publication: "Alert to all @CurveFinance users, their frontend has been compromised! Do not interact with it until further notice! It appears around $570k stolen so far."

How Russia Took Over Ukraine's Internet in Occupied Territories (nytimes.com) 54

Several weeks after taking over Ukraine's southern port city of Kherson, Russian soldiers arrived at the offices of local internet service providers and ordered them to give up control of their networks. From a report: "They came to them and put guns to their head and just said, 'Do this,'" said Maxim Smelyanets, who owns an internet provider that operates in the area and is based in Kyiv. "They did that step by step for each company." Russian authorities then rerouted mobile and internet data from Kherson through Russian networks, government and industry officials said. They blocked access to Facebook, Instagram and Twitter, as well as to Ukrainian news websites and other sources of independent information. Then they shut off Ukrainian cellular networks, forcing Kherson's residents to use Russian mobile service providers instead.

What happened in Kherson is playing out in other parts of Russian-occupied Ukraine. After more than five months of war, Russia controls large sections of eastern and southern Ukraine. Bombings have leveled cities and villages; civilians have been detained, tortured and killed; and supplies of food and medicine are running low, according to witnesses interviewed by The New York Times and human rights groups. Ukrainians in those regions have access only to Russian state television and radio. To cap off that control, Russia has also begun occupying the cyberspace of parts of those areas. That has cleaved off Ukrainians in Russia-occupied Kherson, Melitopol and Mariupol from the rest of the country, limiting access to news about the war and communication with loved ones. In some territories, the internet and cellular networks have been shut down altogether.

India's Rocket Fails To Put Satellites In Right Orbit In Debut Launch 23

India's new rocket launched for the first time on Saturday night (Aug. 6) but failed to deliver its satellite payloads into their intended orbit due to a sensor issue. Space.com reports: The 112-foot-tall (34 meters) Small Satellite Launch Vehicle (SSLV) lifted off from Satish Dhawan Space Centre on India's southeastern coast on Saturday at 11:48 p.m. EDT (0348 GMT and 9:18 a.m. India Standard Time on Sunday, Aug. 7) with two satellites onboard. The rocket's three solid-fueled stages performed well, but its fourth and final stage, a liquid-fueled "velocity trimming module" (VTM), hit a snag: Indian Space Research Organisation (ISRO) officials reported a loss of data from the rocket and, just over five hours after liftoff, ISRO announced the mission had failed.

"The entire vehicle performance was very good" at the start, but ultimately left the two satellites in the wrong orbit, ISRO Chairman S. Somanath said in a video statement after the launch. "The satellites were placed in an elliptical orbit in place of a circular orbit." Instead of placing the satellites in a circular orbit 221 miles (356 kilometers) above Earth, the rocket left them in an orbit that ranged from 221 miles to as close as 47 miles (76 km). That orbit was not stable, and the satellites have "already come down, and they are not usable," Somanath said. ISRO officials said on Twitter that a sensor failure that was not detected in time to switch to a "salvage action" caused the orbit issue. An investigation into the failure is planned.

Hacker Finds Kill Switch For Submachine Gun-Wielding Robot Dog (vice.com) 44

An anonymous reader quotes a report from Motherboard: In July, a video of a robot dog with a submachine gun strapped to its back terrified the internet. Now a hacker who posts on Twitter as KF@d0tslash and GitHub as MAVProxyUser has discovered that the robot dog contains a kill switch, and it can be accessed through a tiny handheld hacking device. "Good news!" d0tslash said on Twitter. "Remember that robot dog you saw with a gun!? It was made by @UnitreeRobotic. Seems all you need to dump it in the dirt is @flipper_zero. The PDB has a 433mhz backdoor."

In the video, d0tslash showed one of the Unitree robot dogs hooked up to a power supply. A hand comes into the frame holding a Flipper Zero, Tamagotchi-like multitool hacking device that can send and receive wireless signals across RFID, Bluetooth, NFC, and other bands. A button is pushed on the Flipper and the robot dog seizes up and falls to the ground. Motherboard reached out to d0tslash to find out how they hacked the robot dog. The power supply in the video is an external power source. "Literally a 24-volt external power supply, so I'm not constantly charging battery while doing dev," d0tslash said.

d0tslash got their hands on one of the dogs and started going through the documentation when they discovered something interesting. Every dog ships with a remote cut-off switch attached to its power distribution board, the part of a machine that routes power from the battery to its various systems. The kill switch listens for a particular signal at 433mhz. If it hears the signal, it shuts down the robot. Some of the Unitree robot dogs even ship with the wireless remote that shuts the dog down instantly. d0tslash then used Flipper Zero to emulate the shutdown, copying the signal the robot dog's remote broadcasts over the 433MHz frequency.
Anyone with a Flipper Zero or similar device can shut down these robot dogs, thanks to the work d0tslash has shared on Github.

Meta's AI Chatbot Repeats Election and Anti-Semitic Conspiracies (bloomberg.com) 146

Only days after being launched to the public, Meta Platforms' new AI chatbot has been claiming that Donald Trump won the 2020 US presidential election, and repeating anti-Semitic conspiracy theories. From a report: Chatbots -- artificial intelligence software that learns from interactions with the public -- have a history of taking reactionary turns. In 2016, Microsoft's Tay was taken offline within 48 hours after it started praising Adolf Hitler, amid other racist and misogynist comments it apparently picked up while interacting with Twitter users. Facebook parent company Meta released BlenderBot 3 on Friday to users in the US, who can provide feedback if they receive off-topic or unrealistic answers. A further feature of BlenderBot 3 is its ability to search the internet to talk about different topics.

The company encourages adults to interact with the chatbot with "natural conversations about topics of interest" to allow it to learn to conduct naturalistic discussions on a wide range of subjects. Conversations shared on various social media accounts ranged from the humorous to the offensive. BlenderBot 3 told one user its favorite musical was Andrew Lloyd Webber's "Cats," and described Meta CEO Mark Zuckerberg as "too creepy and manipulative" to a reporter from Insider. Other conversations showed the chatbot repeating conspiracy theories.

'I Landed a (Model) Rocket Like SpaceX. It Took 7 Years' (hackaday.com) 33

"If you've been following Joe Barnard's rocketry projects for the past few years, you'll know that one of his primary goals has been to propulsively land a model rocket like SpaceX," reports Hackaday.

"Now, 7 years into the rollercoaster journey, he has finally achieved that goal with the latest version of his Scout rocket." Many things need to come together to launch AND land a rocket on standard hobby-grade solid fuel rocket motors. A core component is stabilization of the rocket during the entire flight, which achieved using a thrust-vectoring control (TVC) mount for the rocket motors and a custom flight computer loaded with carefully tuned guidance software. Until recently, the TVC mounts were 3D printed, but Joe upgraded it to machined aluminum to eliminate as much flex and play as possible.

Since solid-fuel rockets can't technically be throttled, [Joe] originally tried to time the ignition time of the descent motor in such a manner that it would burn out as the rocket touches down. The ignition time and exact thrust numbers simply weren't repeatable enough, so in his 2020 landing attempts, he achieved some throttling effect by oscillating the TVC side to side, reducing the vertical thrust component. This eventually gave way to the final solution, a pair of ceramic pincers which block the thrust of the motors as required.

"I have been trying to do what you just saw for seven years," Barnard says in the video, remembering that he started the project back in the fall of 2015. "Not because it's revolutionary or game-changing for model rocketry, but because it's a really cool project, and I knew I would learn a lot." (On Twitter, Barnard added that "I had no background in aero, electrical engineering, coding, etc so it took a lot of trial and error.")

And in the video Barnard made sure to thank his 690 supporters on Patreon — and also shared a surprise. He'd printed out a sheet of paper with the name of every one of his Patreon supporters, rolled it up, and inserted it into the hollow center of his rocket before the flight. "So if you support, you were part of this."

The Patreon account offers more details on Barnard's mission. "Learning by experimentation is the most effective way to gain a deep understanding of new concepts, which is why providing hands-on experience with advanced rocketry components is important for the next generation of scientists, engineers, and astronauts."

And the video ends with Bernard describing the next projects he'll attempt:
  • More SpaceX-like vertical landings
  • A 9-foot model of SpaceX's Starship Super Heavy rocket
  • A special secret project known only as "the meat rocket"
  • An actual model-rocket space shot — that is, a rocket that ascends over 100 kilometers
