Meta 'Supreme Court' Expands with European Center to Handle TikTok, YouTube Cases (msn.com) 19

Meta's Oversight Board "is spinning off a new appeals center," reports the Washington Post, "to handle content disputes from European social media users on multiple platforms".

It will operate under Europe's Digital Services Act, "which requires tech companies to allow users to appeal restrictions on their accounts before an independent group of experts." "I think this is really a game changer," Appeals Centre Europe CEO Thomas Hughes said in an interview. "It could really drive platform accountability and transparency."

The expansion arrives as the Oversight Board, an independent collection of academics, experts and lawyers funded by Meta, has been seeking to expand its influence beyond the social media giant... [The Board] has tried for years to court other major internet companies, offering to help them referee debates about content, The Post has reported...

Oversight Board members and Oversight Board Trust Chairman Stephen Neal said in statements that both the Appeals Centre Europe and the Oversight Board will play critical but complimentary roles in holding tech companies accountable for their decisions on content. "Both entities are committed to improving user redress, transparency and upholding users' rights online," Neal said...

Hughes, who used to be the Oversight Board's administration director, said that he was "proud" of what the Oversight Board is accomplishing but that it is different from what the Appeals Centre Europe will offer. When Facebook, YouTube or TikTok removes a post, European social media users will be able to appeal the decision to the center. Users also will also be able to flag the center with posts they think violate the rules but were not removed. While the Appeals Centre Europe's decisions will be nonbinding, the group will generate data that could power decisions by regulators, civil society groups and the general public, Hughes said. By contrast, the Oversight Board's decisions on Meta content are binding.

Last year the original Oversight Board completed more than 50 cases, "and is on track to exceed that number in 2024," according to the article. But this board is different, CEO Hughes told the Post. They'll have about two dozen staffers, with expertise in human rights and tech policy — or fluency in various languages.

And he added that though the center is funded by an initial grant, future operating costs will be covered by the fees social media companies pay the appeal center — roughly 90 euros ($100) per case.

The Radio-Obsessed Civilian Shaping Ukraine's Drone Defense (technologyreview.com) 42

Former Ukranian officer Serhii "Flash" Beskrestnov created a Signal channel where military communications specialists could talk with civilian radio experts, reports MIT's Technology Review. But radio communications are crucial for drones, so... About once a month, he drives hundreds of kilometers east in a homemade mobile intelligence center: a black VW van in which stacks of radio hardware connect to an array of antennas on the roof that stand like porcupine quills when in use. Two small devices on the dash monitor for nearby drones. Over several days at a time, Flash studies the skies for Russian radio transmissions and tries to learn about the problems facing troops in the fields and in the trenches.

He is, at least in an unofficial capacity, a spy. But unlike other spies, Flash does not keep his work secret. In fact, he shares the results of these missions with more than 127,000 followers — including many soldiers and government officials — on several public social media channels. Earlier this year, for instance, he described how he had recorded five different Russian reconnaissance drones in a single night — one of which was flying directly above his van... Drones have come to define the brutal conflict that has now dragged on for more than two and a half years. And most rely on radio communications — a technology that Flash has obsessed over since childhood. So while Flash is now a civilian, the former officer has still taken it upon himself to inform his country's defense in all matters related to radio...

Flash has also become a source of some controversy among the upper echelons of Ukraine's military, he tells me. The Armed Forces of Ukraine declined multiple requests for comment, but Flash and his colleagues claim that some high-ranking officials perceive him as a security threat, worrying that he shares too much information and doesn't do enough to secure sensitive intel... [But] His work has become greatly important to those fighting on the ground, and he recently received formal recognition from the military for his contributions to the fight, with two medals of commendation — one from the commander of Ukraine's ground forces, the other from the Ministry of Defense...

And given the mounting evidence that both militaries and militant groups in other parts of the world are now adopting drone tactics developed in Ukraine, it's not only his country's fate that Flash may help to determine — but also the ways that armies wage war for years to come.

He's also written guides on building cheap anti-drone equipment...

Boeing Plans to Cut 17,000 Jobs - 10% of Its Workforce (msn.com) 89

"Boeing said Friday it will cull 10 percent of its workforce — roughly 17,000 jobs," reports the Washington Post, "as the aviation giant grapples with mounting losses and manufacturing disruptions amid a machinists strike that has dragged into a fifth week." Executives, managers and production employees will be affected by the cuts, chief executive Kelly Ortberg informed employees Friday in a memo. Boeing will also delay the launch of its 777X plane until 2026 due to ongoing challenges, Ortberg wrote... The layoffs add to the pain at Boeing, where a stalemate between the company's largest employee union dovetails with ongoing legal troubles and safety woes. The strike has halted production of some of the company's best-selling jets, further adding to its financial troubles. In the past five years, Boeing has lost more than $25 billion...

"Our business is in a difficult position, and it is hard to overstate the challenges we face together," Ortberg said in the memo. "The state of our business and our future recovery require tough actions...." Now at risk of a downgrade to its credit rating as its circumstances worsen, Boeing has taken other steps to reduce expenses, including imposing a hiring freeze and eliminating unnecessary travel.

"The strike by Boeing machinists is costing the company roughly $1 billion a month, according to estimates from S&P Global..."

PC Shipments Stuck in Neutral Despite AI Buzz (theregister.com) 81

The PC market is not showing many signs of a rebound, despite the hype around AI PCs, with market watchers split over whether unit shipments are up or down slightly. From a report: Those magical AI PC boxes were supposed to fire up buyer enthusiasm and spur the somewhat listless market for desktop and laptop systems into significant growth territory, but that doesn't appear to be happening. According to the latest figures from Gartner, global PC shipments totaled 62.9 million units during Q3 of this year, representing a 1.3 percent decline compared with the same period last year. However, this does follow three consecutive quarters of modest growth.

"Even with a full line-up of Windows-based AI PCs for both Arm and x86 in the third quarter of 2024, AI PCs did not boost the demand for PCs since buyers have yet to see their clear benefits or business value," commented Gartner Director Analyst Mikako Kitagawa. This is perhaps understandable when AI PCs are largely just a marketing concept, and vendors can't agree on exactly what the the definition of an AI PC should be. Even worse, some buyers of Arm-based Copilot+ machines discovered that their performance isn't actually very good with some applications.

Imgur Is No Longer Classifying Memes With Adult Humor As Mature (theverge.com) 22

Imgur announced changes to its content moderation policies, no longer classifying memes with adult humor as mature. Going forward, only memes with sexualized or lewd content will receive the mature tag. The Verge reports: Imgur is making the changes after it collected feedback about its content moderation over the course of this year, including that its policies, "especially surrounding mature content, feel inconsistently applied, too subjective, or just rather confusing as a whole," according to a post from Imgur product manager Martyn O'Neill. Now, mature content consists "solely of sexualized or 'lewd'" content.

Following the adjustments, O'Neill says that "warnings / post removals" are down nearly 35 percent month over month. Far fewer posts are being marked as mature as well; that stat has declined by almost 50 percent.

Bluesky Is Now Courting Threads Users (thurrott.com) 12

Bluesky, the decentralized social network cofounded by Jack Dorsey, created a Threads account to court users frustrated by Meta's moderation issues. Thurrott reports: This week, the Bluesky team also used Threads to share some tips on how to get started on Bluesky, how to get more engagement, and more. The company also emphasized its decentralized structure and more extensive customization options, with the app recently introducing a new theme font, adjustable font sizing, and the ability to pin posts on top of profiles.

Bluesky also couldn't resist to engage in some strange trolling this week. "We're not like the other girls ... we're not owned by a billionaire," the team wrote on Threads yesterday. Of course, this the post that got the most engagement on the Bluesky Threads account with close to 500 comments as of this writing.

TikTok Execs Know About App's Effect On Teens, Lawsuit Documents Allege (npr.org) 49

An anonymous reader quotes a report from NPR : For the first time, internal TikTok communications have been made public that show a company unconcerned with the harms the app poses for American teenagers. This is despite its own research validating many child safety concerns. The confidential material was part of a more than two-year investigation into TikTok by 14 attorneys general that led to state officials suing the company on Tuesday. The lawsuit alleges that TikTok was designed with the express intention of addicting young people to the app. The states argue the multi-billion-dollar company deceived the public about the risks. In each of the separate lawsuits state regulators filed, dozens of internal communications, documents and research data were redacted -- blacked-out from public view -- since authorities entered into confidentiality agreements with TikTok.

But in one of the lawsuits, filed by the Kentucky Attorney General's Office, the redactions were faulty. This was revealed when Kentucky Public Radio copied-and-pasted excerpts of the redacted material, bringing to light some 30 pages of documents that had been kept secret. A group of more than a dozen states sued TikTok on Tuesday, alleging the app was intentionally designed to addict teens, something authorities say is a violation of state consumer protection laws. After Kentucky Public Radio published excerpts of the redacted material, a state judge sealed the entire complaint following a request from the attorney general's office "to ensure that any settlement documents and related information, confidential commercial and trade secret information, and other protected information was not improperly disseminated," according to an emergency motion to seal the complaint filed on Wednesday by Kentucky officials.

NPR reviewed all the portions of the suit that were redacted, which highlight TikTok executives speaking candidly about a host of dangers for children on the wildly popular video app. The material, mostly summaries of internal studies and communications, show some remedial measures -- like time-management tools -- would have a negligible reduction in screen time. The company went ahead and decided to release and tout the features. Separately, under a new law, TikTok has until January to divest from its Chinese parent company, ByteDance, or face a nationwide ban. TikTok is fighting the looming crackdown. Meanwhile, the new lawsuits from state authorities have cast scrutiny on the app and its ability to counter content that harms minors.

Silicon Valley Is Debating If AI Weapons Should Be Allowed To Decide To Kill (techcrunch.com) 99

An anonymous reader quotes a report from TechCrunch: In late September, Shield AI cofounder Brandon Tseng swore that weapons in the U.S. would never be fully autonomous -- meaning an AI algorithm would make the final decision to kill someone. "Congress doesn't want that," the defense tech founder told TechCrunch. "No one wants that." But Tseng spoke too soon. Five days later, Anduril cofounder Palmer Luckey expressed an openness to autonomous weapons -- or at least a heavy skepticism of arguments against them. The U.S.'s adversaries "use phrases that sound really good in a sound bite: Well, can't you agree that a robot should never be able to decide who lives and dies?" Luckey said during a talk earlier this month at Pepperdine University. "And my point to them is, where's the moral high ground in a landmine that can't tell the difference between a school bus full of kids and a Russian tank?"

When asked for further comment, Shannon Prior, a spokesperson for Anduril said that Luckey didn't mean that robots should be programmed to kill people on their own, just that he was concerned about "bad people using bad AI." In the past, Silicon Valley has erred on the side of caution. Take it from Luckey's cofounder, Trae Stephens. "I think the technologies that we're building are making it possible for humans to make the right decisions about these things," he told Kara Swisher last year. "So that there is an accountable, responsible party in the loop for all decisions that could involve lethality, obviously." The Anduril spokesperson denied any dissonance between Luckey (pictured above) and Stephens' perspectives, and said that Stephens didn't mean that a human should always make the call, but just that someone is accountable.

Last month, Palantir co-founder and Anduril investor Joe Lonsdale also showed a willingness to consider fully autonomous weapons. At an event hosted by the think tank Hudson Institute, Lonsdale expressed frustration that this question is being framed as a yes-or-no at all. He instead presented a hypothetical where China has embraced AI weapons, but the U.S. has to "press the button every time it fires." He encouraged policymakers to embrace a more flexible approach to how much AI is in weapons. "You very quickly realize, well, my assumptions were wrong if I just put a stupid top-down rule, because I'm a staffer who's never played this game before," he said. "I could destroy us in the battle."

When TC asked Lonsdale for further comment, he emphasized that defense tech companies shouldn't be the ones setting the agenda on lethal AI. "The key context to what I was saying is that our companies don't make the policy, and don't want to make the policy: it's the job of elected officials to make the policy," he said. "But they do need to educate themselves on the nuance to do a good job." He also reiterated a willingness to consider more autonomy in weapons. "It's not a binary as you suggest -- 'fully autonomous or not' isn't the correct policy question. There's a sophisticated dial along a few different dimensions for what you might have a soldier do and what you have the weapons system do," he said. "Before policymakers put these rules in place and decide where the dials need to be set in what circumstance, they need to learn the game and learn what the bad guys might be doing, and what's necessary to win with American lives on the line." [...]
"For many in Silicon Valley and D.C., the biggest fear is that China or Russia rolls out fully autonomous weapons first, forcing the U.S.'s hand," reports TechCrunch. "At the Hudson Institute event, Lonsdale said that the tech sector needs to take it upon itself to 'teach the Navy, teach the DoD, teach Congress' about the potential of AI to 'hopefully get us ahead of China.' Lonsdale's and Luckey's affiliated companies are working on getting Congress to listen to them. Anduril and Palantir have cumulatively spent over $4 million in lobbying this year, according to OpenSecrets."

Ukraine Arrests VPN Operator Facilitating Access to Russian Internet (circleid.com) 122

penciling_in writes: Ukrainian authorities have arrested a 28-year-old man in Khmelnytskyi for running an illegal VPN service that allowed users to bypass Ukrainian sanctions and access the Russian internet (Runet). The VPN, active since Russia's invasion, enabled Russian sympathizers and people in occupied territories to reach blocked Russian government sites, social media, and news.

Handling over 100GB of data daily and linking to 48 million Russian IP addresses, the VPN may have been exploited by Russian intelligence. Ukrainian cyber police, in collaboration with the National Security Service, seized servers and equipment in multiple locations. The suspect faces charges under Part 5 of Article 361 of Ukraine's Criminal Code, which could lead to a 15-year prison sentence. Investigations are ongoing into further connections and funding sources. The case highlights the growing role of VPNs in the ongoing cyberwar between Ukraine and Russia.

Former Google Chief Urges AI Investment Over Climate Targets (windowscentral.com) 81

Former Google CEO Eric Schmidt urged prioritizing AI infrastructure over climate goals at a Washington AI summit this week. Schmidt, who led Google until 2011, argued that AI's rapid growth will outpace environmental mitigation efforts. "We're not going to hit the climate goals anyway because we're not organized to do it," Schmidt told attendees, addressing concerns about AI's surging energy demands.

Data centers powering AI are projected to consume 35 gigawatts annually by 2030, up from 17 gigawatts in 2023, according to McKinsey. Schmidt, now heading AI drone company White Stork, suggested AI could ultimately solve climate issues, stating, "I'd rather bet on AI solving the problem than constraining it."

US Military Spaceplane To Perform Orbital Maneuvers (spacenews.com) 18

In a rare disclosure, the U.S. Space Force announced that its secretive X-37B spaceplane will execute a series of maneuvers before returning back to Earth. SpaceNews reports: The reusable spacecraft, which has been in orbit since December 28, 2023, will perform aerobraking maneuvers to alter its trajectory around Earth, the Space Force said Oct. 10. This technique involves making multiple passes through the planet's upper atmosphere, using atmospheric drag to modify the vehicle's orbit while conserving fuel. These maneuvers also are intended to showcase responsible space operations, the Space Force said. The aerobraking enables the spaceplane to change orbits and comply with space debris mitigation rules by safely discarding the service module.

The X-37B, manufactured by Boeing, is jointly operated by the U.S. Space Force and the Air Force Rapid Capabilities Office. Since its launch aboard a SpaceX Falcon Heavy rocket from NASA's Kennedy Space Center in Florida, the spaceplane has been conducting radiation effect experiments and testing space domain awareness technologies in a highly elliptical orbit. [...] After completing its aerobraking maneuvers, the X-37B will resume its testing and experimentation objectives. Once these are accomplished, the vehicle will de-orbit and return to Earth, utilizing its autonomous landing system to touch down horizontally like a conventional aircraft. The Space Force has not disclosed the expected duration of the current mission.

Elon Musk Unveils Tesla Cybercab, Robovan and Updated Optimus Robot 251

At Tesla's "We, Robot" event at Warner Bros. Studios tonight, Elon Musk unveiled the Tesla Cybercab, Robovan, and an updated version of the Optimus robot. Slashdot is at the event capturing photos and getting demos of everything announced. You can follow along on X. Below is a summary of each of the offerings.

Tesla Cybercab: The Tesla Cybercab is a futuristic, fully autonomous robotaxi designed without a steering wheel or pedals, positioned to revolutionize mass transit with extremely low operating costs. It features a sleek design with upward-opening butterfly doors and a compact cabin that seats two passengers. Musk said the Cybercab uses inductive charging instead of a traditional plug-in. "Something we're also doing is and it's really high time we did this is inductive charging. So the robotaxi has no plug it just goes over the inductive charger and charges so yeah, it's kind of how it should be." The vehicle is expected to cost under $30,000. Regulatory approval will be needed before it can go into production, which is projected to begin by 2026 or 2027. Tesla Robovan: The Tesla Robovan is a dustbuster-shaped electric passenger van featuring sliding glass doors, a bright interior, and carriage-style seating for up to 20 passengers. "One of the things we want to do and we've seen this with the CyberTruck is we want to change the look of the roads the future should look like the future," said Musk. Musk also claimed that autonomy will "turn parking lots into parks," as fewer cars will be needed and they won't sit idle for most of the day. Pricing and release details were not disclosed. Tesla Optimus: The updated Tesla Optimus robot is a humanoid designed to handle everyday tasks, such as retrieving packages or serving drinks. Optimus walked on stage and interacted with attendees, though its current capabilities are still limited. Elon Musk envisions the robot as a transformative product, with plans to produce millions of units at a price of around $20,000. "It'll be able to do anything you want. So it can be a teacher, babysit your kids, it can walk your dog, mow your lawn, get the groceries, just be your friend, serve drinks. Whatever you can think of, it will do." Optimus is expected to start performing useful tasks by the end of the year, with broader availability projected by the end of next year. In closing, Musk said: "I think this will be the biggest product ever of any kind. Because I think everyone of the 8 billion people of Earth, I think everyone's going to want their Optimus buddy."

AMD Launches AI Chip To Rival Nvidia's Blackwell (cnbc.com) 30

AMD is launching a new chip to rival Nvidia's upcoming Blackwell chips, which Nvidia called the "world's most powerful chip" for AI when unveiled earlier this year. CNBC reports: The Instinct MI325X, as the chip is called, will start production before the end of 2024, AMD said Thursday during an event announcing the new product. If AMD's AI chips are seen by developers and cloud giants as a close substitute for Nvidia's products, it could put pricing pressure on Nvidia, which has enjoyed roughly 75% gross margins while its GPUs have been in high demand over the past year. In the past few years, Nvidia has dominated the majority of the data center GPU market, but AMD is historically in second place. Now, AMD is aiming to take share from its Silicon Valley rival or at least to capture a big chunk of the market, which it says will be worth $500 billion by 2028.

AMD didn't reveal new major cloud or internet customers for its Instinct GPUs at the event, but the company has previously disclosed that both Meta and Microsoft buy its AI GPUs and that OpenAI uses them for some applications. The company also did not disclose pricing for the Instinct MI325X, which is typically sold as part of a complete server. With the launch of the MI325X, AMD is accelerating its product schedule to release new chips on an annual schedule to better compete with Nvidia and take advantage of the boom in AI chips. The new AI chip is the successor to the MI300X, which started shipping late last year. AMD's 2025 chip will be called MI350, and its 2026 chip will be called MI400, the company said.

Windows 11's New Passkey Design Includes Cloud Syncing, 1Password Integration (theverge.com) 19

Microsoft is enhancing passkey support in Windows 11 with a redesigned Windows Hello experience that allows users to sync passkeys to their Microsoft account or third-party providers like 1Password and Bitwarden. The Verge reports: A new API for third-party password and passkey managers means developers can plug directly into the Windows 11 experience, so you can use the same passkey from your mobile device to authenticate on your PC. Right now it's possible in some apps to do this through QR codes and other ways to authenticate from a mobile device, but Microsoft's full support means the passkeys experience on Windows is about to get a lot better.

Microsoft is also redesigning the Windows Hello prompt, including the ability to setup syncing of passkeys to your Microsoft account or saving them elsewhere. Once you've completed a one-time setup process you can use facial recognition, fingerprint, or PIN to authenticate with a passkey across multiple Windows 11 devices.
Windows Insiders will get access to these new passkey features "in the coming months."

Hacktivists Claim Responsibility For Taking Down the Internet Archive (gizmodo.com) 91

An anonymous reader quotes a report from Gizmodo: The Internet Archive and Wayback Machine went down on Tuesday following a sustained cyber attack. In addition, the Archive's user data has been compromised. If you've ever logged into the site to pore over its ample archives, it's time to change your passwords. [...] A pro-Palestenian hacktivist group called SN_BLACKMETA has taken responsibility for the hack on X and Telegram. "They are under attack because the archive belongs to the USA, and as we all know, this horrendous and hypocritical government supports the genocide that is being carried out by the terrorist state of 'Israel,'" the group said on X when someone asked them why they'd gone after the Archive.

The group elaborated on its reasoning in a now-deleted post on X. Jason Scott, an archivist at the Archive, screenshotted it and shared it. "Everyone calls this organization 'non-profit', but if its roots are truly in the United States, as we believe, then every 'free' service they offer bleeds millions of lives. Foreign nations are not carrying their values beyond their borders. Many petty children are crying in the comments and most of those comments are from a group of Zionist bots and fake accounts," the post said.

SN_BLACKMETA also claimed responsibility for a six-day DDoS attack on the Archive back in May. "Since the attacks began on Sunday, the DDoS intrusion has been launching tens of thousands of fake information requests per second. The source of the attack is unknown," Chris Freeland, Director of Library Services at the Archive said in a post about the attacks back in May. SN_BLACKMETA launched its Telegram channel on November 23 and has claimed responsibility for a number of other attacks including a six-day DDoS run at Arab financial institutions and various attacks on Israeli tech companies in the spring.

EU Delays New Biometric Travel Checks as IT Systems Not Up To Speed (usnews.com) 18

The European Union has delayed the introduction of a new biometric entry-check system for non-EU citizens, which was due to be introduced on Nov. 10, after Germany, France and the Netherlands said border computer systems were not yet ready. From a report: "Nov. 10 is no longer on the table," EU Home Affairs Commissioner Ylva Johansson told reporters. She said there was no new timetable, but that the possibility of a phased introduction was being looked at. The Entry/Exit System (EES) is supposed to create a digital record linking a travel document to biometric readings confirming a person's identity, removing the need to manually stamp passports at the EU's external border. It would require non-EU citizens arriving in the Schengen free-travel area to register their fingerprints, provide a facial scan and answer questions about their stay.

Google Identifies Low Noise 'Phase Transition' In Its Quantum Processor (arstechnica.com) 31

An anonymous reader quotes a report from Ars Technica: Back in 2019, Google made waves by claiming it had achieved what has been called "quantum supremacy" -- the ability of a quantum computer to perform operations that would take a wildly impractical amount of time to simulate on standard computing hardware. That claim proved to be controversial, in that the operations were little more than a benchmark that involved getting the quantum computer to behave like a quantum computer; separately, improved ideas about how to perform the simulation on a supercomputer cut the time required down significantly.

But Google is back with a new exploration of the benchmark, described in a paper published in Nature on Wednesday. It uses the benchmark to identify what it calls a phase transition in the performance of its quantum processor and uses it to identify conditions where the processor can operate with low noise. Taking advantage of that, they again show that, even giving classical hardware every potential advantage, it would take a supercomputer a dozen years to simulate things.

DIY Photographer Builds Full-Frame Camera, Open-Sources the Project (dpreview.com) 27

Boston-based engineer and photographer Wenting Zhang built his own full-frame camera and open-sourced the project on GitLab for anyone else to build upon. The camera, named Sitina S1, features a 10MP CCD sensor, custom electronics, and a 3D-printed body. Digital Photography Review reports: Zhang says he started the project in 2017, and it's not finished yet. "Engineers are usually bad at estimating how long things will take. I am probably particularly bad at that. I expected this project to be challenging, so it would take a bit longer, like probably one year. Turned out my estimation was off," he says. He makes clear to point out that this is a hobby project, purely for fun, and that his camera isn't going to achieve the level of image quality found in commercially available products from established companies. Despite that, his project provides a fascinating look into what's involved in building a camera from the ground up.

Although CMOS has become the dominant sensor technology in consumer cameras, owing to factors like speed, lower power consumption and cost, Zhang's camera is built around a 10MP Kodak KAI-11000CM CCD sensor with a global electronic shutter, which he selected for a rather pragmatic reason: it was easy to source. "Most manufacturers (like Sony) aren't going to just sell a sensor to a random hobbyist, so I have to buy whatever is available on eBay. This 10MP CCD turned out to be available," he explains. The choice of sensor has a useful benefit. As he explains in one of his videos, designing and building a mechanical shutter is complicated and beyond his area of expertise, so his DIY design is based on using an electronic shutter. For similar reasons, he chose to use an LCD screen as a viewfinder rather than a prism-based optical design, resulting in a mirrorless camera.

Zhang wanted his design to be compatible with existing lenses. His mirrorless design, with a short flange distance, provided a great deal of flexibility to adapt different lenses to the camera, and he's currently using E-mount with active electrical contacts. And that's just the start. Zhang also needed to integrate a CCD signal processor with an ADC (analog to digital converter), a CPU, battery, an LCD screen and buttons. He also designed and built his own circuit board with a power-only USB port, flash sync terminal, power button and SD card slot, and create the software and user interface to tie it all together. Finally, everything fits inside a 3D-printed enclosure that, to my eye, looks rather attractive.
