Pine64 Touts Its RISC-V-Based Single-Board Computer and Soldering Irons
Just as a short recap: Star64 comes with a StarFive JH7110 64bit CPU sporting quad SiFive FU740 cores clocked at 1.5GHz. The SOC is equipped with BXE-2-32 from Imagination Technologies, which is said to be a solid mid-range GPU. Star64 will be available in two configurations — with 4Gb and 8GB of RAM, similarly to the Quartz64. Both hardware versions include USB 3.0 and a PCIe slot as well as two native Gigabit Ethernet NICs…. Along the long leading edges you’ll find PCIe on one end and GPIO on the other. At one end of the board you’ll find a digital video output, a double-stacked Gigabit Ethernet port and a 12V barrel plug for power. On the opposite side, you’ll find 3x USB 2.0, 1x USB 3.0, an audio jack as well as a power button. There are also two U.FL ports for antennas — one for bluetooth and the other for WiFi….
The Star64 also has an MiPi display output complete with a touch panel (TP) input, a 12V power port, a CSI camera port and an eMMC slot. A micro SD card slot can be found at the bottom of the PCB. Similarly to the RockPro64 and Quartz64, the 12V port on the Star64 can be used for powering other hardware directly from the board — a popular example is powering one or multiple SSDs connected to a PCIe SATA adapter. I’ll add that, at least in theory, the Star64 would make a great network-attached storage device because of its SoCs low thermals and idle power. I am looking forward to seeing NAS-focused Linux or BSD* OSes available for the board.
Speaking of software, efforts to support the SoC in Linux have already begun. I’ve been told that both Debian and Fedora are already being ported to the StarFive JH7110, which is great news. We are certain that many other OSes will follow swiftly — especially once we start delivering the Star64 to interested developers. On the subject of availability: the Star64 will be available in a few weeks time, and will initially be available to developers. Given the interest in the Star64’s and the SoC powering I hope to see functional distributions available for the board soon after launch.
The announcement also included an update on their PinecilV2 smart mini portable soldering iron (built with a 32-bit RISC-V SoC). “The Pinecil V2 landed earlier this month and sold out almost instantly. The next production run of the ought to be available soon however…”

Need an affordable computer to run basic software? Consider this refurbished MacBook Air.
TL;DR: As of August 24, you can get a Refurbished MacBook Air for just $290.99 instead of $1,399 — that’s a 79% discount.
The newest, flashiest computers have some great bells and whistles, but you probably don’t need the latest hardware if you’re just checking emails or running Google Docs. And while 5TB of hard drive space could be great, you could get more with good cloud storage without worrying about losing everything to a wayward cup of coffee.
It may make more sense to consider a beater computer that can run your basic, everyday programs than an expensive computer that usually runs essential software. This refurbished MacBook Air is on sale for just $290.99, and it could be an excellent machine for simple computing that has to get done daily.
An affordable alternative to a brand-new computer
If you spend a lot of your computer time in Google Suite, Microsoft Office, or other lightweight productivity programs, then you may not need a high-cost, top-spec machine. This refurbished MacBook has an Intel Core i5 processor, a 256GB SSD, and 4GB of RAM. It isn’t the most powerful computer, but it could be an affordable workhorse if your typical workflow doesn’t involve demanding apps like 4K video editing, 3D modeling, or testing games. This one even comes with a wireless mouse.
You could also use this little computer as an excellent streaming machine. Want to enjoy a documentary on a wider screen than your phone’s while still being able to move around the house? Throw it onto your MacBook Air. You could even connect a wireless speaker or headphones via Bluetooth for more immersive sound.
Though this is a refurbished computer, it has a “B” rating, meaning it may only have some light scuffing, dings, or dents on the body of the computer. Of course, those could also be covered up by the snap-on black case that’s included with this bundle.
Delegate some of your computing to an affordable laptop
You may not need a brand new computer for the work you’re doing. Instead, get this refurbished MacBook Air for $290.99 (Reg. $1,399).

Please, Lego, let this engineer bring your computer brick to life
James Brown loves building weird displays. Like animatronic skulls, or mechanical bit-flipping cellular automatons. Or, in this case, an entire computer inside a mock Lego brick.
Not just any brick, either. I’m talking about the classic sloped Lego computers from our childhood spaceships, now brilliantly brought to life. They display fake radar scans, scrolling text, even an interactive homage to the Death Star trench run targeting computer that moves when you touch the exposed Lego studs.
@verge James Brown bought the tiniest, cheapest OLED screens he could find. He wanted to build a keyboard, but his mind’s eye soon saw an even more perfect combination. He tells The Verge he probably won’t sell them — at least not without legal…
Prototype Apple-1 computer used by Steve Jobs auctioned for almost $700,000
An anonymous collector in the San Francisco Bay Area just bought the only known Apple-1 prototype in existence for $677,196 at an auction. While we’ve seen Apple-1 computers sell for similar amounts at auctions before, this one is particularly unique as it’s the prototype Apple co-founder Steve Jobs used as…
NASA astronauts on Artemis could talk to a spaceship computer
Captain Kirk, Spock, and the rest of the Star Trek gang were in constant dialogue with the onboard Enterprise computer, asking it questions about the starship and their alien environments.
With NASA reviving its human space exploration program in a matter of days through Artemis, it seems only natural real astronauts of the 2020s who will crew the forthcoming missions would do the same. After all, boldly going where no one has gone before could be lonely, and having an A.I. sidekick might help on those long voyages.
When Lockheed Martin, the company that built the new Orion spacecraft for NASA, first dreamed up the talking computer, engineers figured they’d just throw an Amazon Echo Dot on the dashboard with a laptop and call it a day. But it wasn’t nearly that simple, said Rob Chambers, Lockheed’s director of commercial civil space strategy.
Beyond technical constraints, they had to overcome the menacing representations of an inflight space computer, in the vein of Stanley Kubrick’s 2001: A Space Odyssey. Unlike the collegial computer in Star Trek, “HAL” starts to glitch, takes control of the spacecraft, and then fights the crew’s attempts to shut it down.
That’s not merely a concern raised through science fiction. This summer A.I. developer Blake Lemoine, formerly of Google, went public with his belief that a chatbot he helped build had become sentient. The story sparked a global conversation about whether some artificial intelligence is — or could be — conscious.

Such claims work to reinforce fears long embedded in popular culture — that one day the advanced technology enabling humans to achieve extraordinary things could be too smart, perhaps leading to machines that are self aware and want to hurt people.
“We don’t want the HAL 9000, ‘I’m sorry, Dave. I can’t open the pod bay doors,'” Chambers told Mashable. “That’s the first thing that everybody said when we first suggested this.”
“We don’t want the HAL 9000, ‘I’m sorry, Dave. I can’t open the pod bay doors.That’s the first thing that everybody said when we first suggested this.”
Rather, Lockheed Martin and its collaborators believe having a voice-activated virtual assistant and video calls in the spacecraft would be more convenient for astronauts, affording them access to information away from the crew console. That flexibility might even keep them safer, engineers say.
An experiment to test the technology will ride along with Artemis on its first spaceflight, which could launch as early as Aug. 29. The project, named Callisto after one of Artemis’ favorite hunting companions in Greek mythology, is programmed to give crew live answers about the spacecraft’s flight status and other data, such as water supply and battery levels. The technology is being paid for by the companies — not NASA.
A custom Alexa system built specifically for the spacecraft will have access to some 120,000 data readouts — more than astronauts have had before, with some bonus information previously only available within Houston’s mission control.

No astronaut will actually be onboard Orion for this first mission — unless the dummy in the cockpit counts. But the inaugural 42-day spaceflight, testing various orbits and atmosphere reentry, will clear the way for NASA to send a crew on subsequent missions. Whether a virtual assistant is integrated into the spacecraft for those expeditions depends on a successful demonstration during Artemis I.
To test their Alexa, mission control will use video-conferencing software provided by Cisco Webex to ask questions and give verbal commands inside the spacecraft. Cisco will run its software on an iPad in the capsule. Cameras mounted all over Orion will monitor how it’s working.

For the most part, the virtual assistant will be answering queries, like “Alexa, how fast is Orion traveling?” and “Alexa, what’s the temperature in the cabin?” The only thing the system can actually control are the lights, said Justin Nikolaus, an Alexa voice designer on the project.
“As far as control of the vehicle, we don’t have access to any critical components or mission critical software onboard,” Nikolaus told Mashable. “We’re safely sandboxed in Orion.”
The space-faring Alexa might not seem so advanced. But engineers had to figure out how to get the device to recognize a voice in a tin can. The acoustics of Orion, with mostly metal surfaces, were unlike anything developers have encountered before. What they learned from the project is now being applied to other challenging sound environments on Earth, like detecting speech in a moving car with the windows rolled down, Nikolaus said.
The most significant change from off-the-shelf Amazon devices is that the system will debut a new technology the company calls “local voice control,” which allows Alexa to work without an internet connection. Back on Earth, Alexa operates on the cloud, which runs on the internet and uses computer servers warehoused in data centers.
In deep space, when Orion is hundreds of thousands of miles away, the time delays to reach the cloud would be, shall we say, astronomical. Looking toward the future, that lag could stretch from seconds to an hour to transmit messages back and forth to a spacecraft on its way to Mars, about 96 million miles from Earth.
That’s why engineers built a spacecraft computer to handle the data processing, Chambers said.
“It’s not canned things. It’s actual real-time processing,” he said. “All that smarts has to be on the spacecraft because we didn’t want to suffer the time lag of going back up to the spacecraft, back down to Earth, back up, and back down again.”

For the questions that Alexa can’t handle offline, Callisto will tap into the Deep Space Network, the radio dish system NASA uses to communicate with its farthest spacecraft, and route the signals to the cloud on Earth. This could allow Callisto to support a wider range of requests, like reading the news or reporting sports scores.
Or ordering more toilet paper and trash bags — seriously.
The designers built in the capability for astronauts to buy things from Amazon. Overnight delivery to the moon wouldn’t be an option, but sending flowers to a spouse on Earth for a special occasion would.
Cisco also will use the Deep Space Network to provide video-conferencing calls. Engineers say astronauts would be able to use this tool for “whiteboarding” meetings with their Houston colleagues. Imagine how handy that would have been for the Apollo 13 crew as NASA tried to talk them through how to make a round air filter fit into a square hole with no visual aids.
Broadcasting pictures in high resolution across the solar system isn’t easy, especially with such limited data capacity. One of the reasons Lockheed Martin chose Cisco as a collaborator was for the company’s expertise in video compression, Chambers said. As video travels through space, the data can get garbled. Cisco worked on error-correction technology to smooth out the transmissions.
“One of my colleagues at Cisco refers to this as trying to do 4K, high bandwidth, gigabit-type ethernet, using a 1980s dial-up modem,” he said. “Obviously, the Deep Space Network is very, very capable, but we’re trying to do modern video-conferencing.”
“One of my colleagues at Cisco refers to this as trying to do 4K, high bandwidth, gigabit-type ethernet, using a 1980s dial-up modem.”
To make the custom virtual assistant, the collaborators spent time interviewing astronauts. One of the things they asked for was a dictation service, Nikolaus said. Often their notepads and pens float away. It’s hard to use a computer in a weightless environment, too.
“If you go to a keyboard and you’re not used to microgravity and you start typing, your force on the keyboard pushes your body away from it,” Nikolaus said.
But: Alexa, can you fly me to the moon?
Yes, if what you want is a little Frank Sinatra crooning through the cabin.
Alexa, can you open or close the pod bay doors?
Fortunately, no. The system can’t do anything to put the astronauts in danger, Chambers said.
“We think about that a lot, not necessarily that they’ll become sentient and, you know, Rise of the Machines, and [become] our software overlords,” he said.
But software is complex. Strange behaviors can occur through unexpected convolutions of activities, he said: “What we do is we architect the system such that it is actually not possible for this device to talk to this other device.”
So if all goes according to plan, perhaps the most havoc the real HAL could cause is to prank an astronaut’s family with an unwanted Amazon Fresh pizza delivery.
