Tesla Semi enters volume production after years of delays

Published

on

The takeaway: Tesla has begun volume production of the Semi, its battery-electric heavy truck, at a new facility next to Gigafactory Nevada. The launch marks a more serious commercial phase for the Semi after years of delays. The company says the first Semis produced at the new factory are now being delivered to customers.

The Sparks, Nevada, plant can eventually produce 50,000 trucks a year, or about 1,000 a week, according to Tesla. Before this milestone, the company delivered a small number of trucks to PepsiCo in 2022, but those vehicles were built on a pilot line.

Tesla used an event at the factory to highlight changes made to the truck’s battery, powertrain, and charging system. It also named customers that include PepsiCo, US Foods, DHL, WattEV, ABF Freight, Einride, IMC Logistics, and OK Produce.

The Semi will be sold in two versions. Tesla lists the Standard Range model at 325 miles of range when hauling a full 82,000-pound gross combination weight trailer. The Long Range model is rated for 500 miles under the same conditions. Tesla executives said the Long Range truck could reach about 600 miles with a lighter load of roughly 60,000 pounds.

Tesla has not released current prices or total reservation figures. When the company introduced the Semi in 2017, it set the starting price at $150,000 for a 300-mile version and $180,000 for a 500-mile version. Electrek reported earlier this year that Tesla was quoting some customers about $290,000 for the 500-mile truck.

The production Semi uses Tesla’s 4680 battery cells rather than the 2170 cells used in earlier test vehicles. Tesla says the truck’s battery pack has 822 kWh of capacity. The company says it has reduced the truck’s energy consumption to about 1,700 watt-hours per mile when fully loaded, down from an original target of 2,000 Wh/mile.

Those efficiency gains are important because they allow Tesla to use a lighter battery pack while maintaining its range target. The company also said it cut nearly 1,000 pounds from the truck during development.

Tesla also reworked the drive system. The earlier design used a carbon-fiber-sleeved rotor. The production version uses a steel-caged rotor and a bar-wound stator that Tesla also uses in the Cybertruck. Tesla says the redesigned drive axle is about 80 kilograms lighter.

The company also simplified the truck’s lubrication system. The hub no longer uses oil, while the motor and gearbox share a single oil supply. Tesla says that oil should last more than 250,000 miles.

The Semi now has redundant electric power steering instead of hydraulic steering. Tesla says the new system gives drivers better response and control. It also allows a tighter wheel cut, which the company says brings the Semi’s turning radius close to that of a Model Y. That could matter in crowded industrial yards, city streets, and loading docks.

Tesla has also carried over elements of the Cybercab’s thermal-management system. The Semi uses an indirect system with pumps, compressors, and heat exchangers that manage temperatures across the cab, battery, and drive unit. Tesla says the design reduces the amount of refrigerant plumbing needed throughout the vehicle and can move heat where it is needed.

Charging remains one of the larger questions around the truck. A Semi’s 822-kWh pack requires far more power to charge than a passenger EV. Tesla is building Megacharger stations that can provide as much as 1.2 megawatts per stall. At the event, Tesla showed a truck charging from 3% to 60% in about 30 minutes.

The company says it plans to have more than 30 Semi charging locations, with over 200 megawatt-capable charging posts, by the end of the year. It also expects fleet operators to install overnight charging equipment at their own facilities.

Tesla is pitching the Semi as a fleet product with remote diagnostics, mobile service, over-the-air updates, and driver profiles that can follow drivers from one truck to another. It says its current Semi fleet has recorded more than 98% uptime.

Some fleet operators have already placed large orders. Einride announced a 500-truck deal in August. IMC Logistics said this week that it plans to buy 50 Semis for California drayage work. A shipper coalition also selected Tesla to provide 2,500 trucks for zero-emission freight operations in California.

Tesla argues that electric trucks can cost less to operate than diesel models because they require less maintenance and are less exposed to swings in fuel prices. “You know, volatility in the oil market and the diesel market goes up and down,” Tesla Vice President of Engineering Lars Moravy told The Verge. “But typically, we’ve seen in the history of the last 20 years, electricity is pretty flat. And wouldn’t it be great to have a flat cost in your shipping rates?”

‘The prophecy is fulfilled’: Popular 2020 XKCD comic predicted ‘HEIF Heist’ OpenAI hack and even mentions ImageMagick in spooky coincidence

Published

on


  • Hacktron chained a libheif heap overflow, reached through ImageMagick on OpenAI’s Discourse forum, leveraging an OpenAI SSO flaw to briefly take over employee ChatGPT and Codex accounts
  • The researchers themselves invoked XKCD #2347, whose 2020 alt text happens to name ImageMagick as the dependency that will one day break
  • ImageMagick served as only the pathway to the actual vulnerable component, libheif, an obscure decoder pulled in indirectly across Slack, Meta, and GitHub Enterprise amongst other mediums

When Hacktron AI recently disclosed its months-long libheif research, the researchers reached for a familiar picture that also, to some degree, hints at what let them break into OpenAI in the first place.

They pointed readers to xkcd #2347, Randall Munroe’s 2020 iconic web cartoon of all modern digital infrastructure balanced on a single load-bearing block that some random person in Nebraska has been thanklessly maintaining.

Why Some Smartphones Have Worse Repairability Than Others

Published

on





Not too long ago, we could easily replace the battery on many smartphones. All one had to do was take off the back cover, take out the existing battery, add the new one, and put the panel back in place. It usually took less than a minute. But those days are long gone, with most smartphones now sealed shut with glue, making simple repairs and part replacements incredibly difficult at home. You need a solid understanding of the hardware side of things and the required tools before you can attempt something like that. Even then, a small mistake can damage other components and render the phone completely unusable.

This doesn’t mean every smartphone on the market is unrepairable. But leading smartphone brands don’t generally fare well. According to the US PIRG “Failing The Fix” 2026 report, Apple ranked last for smartphone repairability with a D- grade, Samsung right above it with a D grade, and Google with a C-. Motorola, on the other hand, bagged the top spot with a B+ grade. If we look at iFixit’s repairability scores, two smartphones, Fairphone 5 and Fairphone 6, earn a perfect 10/10.

That brings us to the more important question: what changed in the past few years that many smartphones now have poor repairability? It all comes down to new design choices manufacturers prioritize and the push to encourage users to upgrade sooner.

Slimmer and waterproof designs are the biggest reasons

In the past few years, smartphone brands have achieved slimmer designs. The iPhone Air is one example, with a thickness of just 5.64 mm. That’s impressive for a smartphone packed with features. But these sleeker, slimmer smartphones can come with a downside: they are not as easy to repair. Smartphones now have components packed more closely together, making at-home repairs difficult, if not outright impossible. Newer designs rely heavily on adhesives to hold everything together, whether it’s the battery, display, or back cover. Even iFixit highlights this use of adhesives as a major drawback on most of the newer smartphones, including those from Apple, Samsung, and Google.

Adhesives do have benefits, especially when it comes to improving smartphones’ structural integrity and making them slimmer and more waterproof. But unlike screws, adhesives also make at-home repairs incredibly challenging. As for doing away with removable batteries and using adhesives to hold them in place, companies generally cite similar reasons, including stronger, slimmer designs and improved water resistance. Apart from that, even the screws used in smartphones aren’t that straightforward. iFixit notes that some modern iPhones have four to five different screwhead types, which complicates repairs.

If you haven’t guessed it already, foldable phones are more difficult to repair because of their complex designs. This added complexity can also increase repair costs. So, you may end up spending more in the long run.

Some phones are still repairable

All that said, it’s not like every smartphone on the market scores poorly on repairability. Some newer brands are making highly repairable phones, with Fairphone and HMD being notable examples. Fairphone, for instance, boasts of streamlined repairs and replacement across its smartphone lineup, with over 40 easily replaceable components. More importantly, these companies incorporate repair-friendly designs and provide clear guides and instructions to allow for common repairs to be performed at home.

Even Apple is moving in a similar direction, although it has links with associations lobbying against Right to Repair. With the launch of Repair Assistant, Apple has made repairs and replacements much easier. For example, professionals, or users themselves, can swap the battery on an iPhone without contacting Apple, as the Repair Assistant handles the calibration. This has, to an extent, addressed the problem of parts pairing. However, you still can’t officially repair or replace every part on every iPhone model. Newer Samsung phones, too, are relatively easier to repair, although it’s still not at the same level as Fairphone.

So, if you are planning to buy a smartphone, you know which brands or models to steer clear of, or at least what you need to check before finalizing one. Better repairability doesn’t just save you money on repairs. It also ensures that your smartphone lasts longer and, at the same time, helps reduce e-waste, a major problem the world is facing right now.

Cities Across US Oppose Trump FCC Plan to Preempt Local Broadband Rules

Published

on

Ars Technica reports:

Cities and counties around the U.S. are angry at the Trump administration over a proposal to override local rules that govern the deployment of wired broadband networks… The Federal Communications Commission [FCC] argues that too many local governments “excessively delay approvals and seek to extract exorbitant sums from providers, resulting in costs that render some deployments infeasible.” The FCC plan is supported by broadband providers, but local governments told the FCC that it would override rules that protect public safety.

Local governments say the plan is illegal and that the FCC should instead focus on how Internet providers thwart competition with permit-hoarding and other tactics that prevent competitors from deploying networks… They object to FCC plans to impose a 120-day deadline for processing permits and to proposed limits on fees and compensation that local governments can require from providers… Another filing submitted by the League of California Cities said the FCC has no authority to adopt the proposal. “Federal preemption of traditional state and local authority over public property, construction, public safety, permitting, and rights-of-way management should rest on clear congressional authorization,” the filing said. “The commission should not infer broad preemptive authority where Congress did not expressly provide it….”

A filing by Minnesota cities said the current FCC is making the same mistake it made during the first Trump administration, when its attempt to preempt state net neutrality laws was blocked in court… If the FCC finalizes its new preemption plan, city and state governments could sue and ask a court to rule that the agency exceeded its authority…

Democratic Commissioner Anna Gomez approved the step of asking the public for input but signaled she would vote against the final proposal. “I am dubious about the commission’s authority under Section 253 to use rulemaking to preempt states and localities when it comes to their management of rights of way and fees charged to providers,” she said.

Cricut’s New DIY Machines Let You Print And Cut Your Own Stickers

Published

on

The Cricut StickerPix Print and Print + Cut could birth a generation of sticker moguls. 

Cricut, maker of a growing lineup of cutting, embossing and heat pressing machines for home crafters, is going all in on stickers. The new Cricut StickerPix Print and StickerPix Print + Cut make it easy to print custom stickers, and, in the case of the Print + Cut, combine the company’s cutting tech with a printer for the first time.

The Cricut StickerPix Print is the smaller of the two machines at 7.8 x 5 x 3.5 inches, and is capable of printing on 4 x 6-inch photo paper or pre-cut sticker sheets from Cricut. The StickerPix Print + Cut is larger at 8 x 11.3 x 4.1 inches and can work with 4 x 7-inch sticker sheets and 4 x 6-inch photo paper. Because the machine can cut, you’re also not limited to the predetermined shapes of Cricut’s pre-cut sticker sheets. 

Both the Print and the Print + Cut use dye-sublimation to print photos and stickers, which means they apply heat to transfer dye directly onto whatever material you’re printing on. They then add a laminate layer that makes your prints water, scratch and fade-resistant. Other Cricut machines require the use of an inkjet printer and special laminate sheets to get similar results, which means if you’re just interested in printing photos and stickers, the Cricut StickerPix could save you a lot of space.

Unlike Cricut’s other machines, though, both the Print and the Print + Cut can only make what are called kiss-cut stickers that come still attached to a single sheet, rather than the die-cut stickers that are separated from their backing paper as they’re cut. Like all of the company’s machines, you’ll also have to use the Cricut Design Space software on your phone or computer to use either StickerPix, which means you’ll likely also be pushed to pay for Cricut Access, a subscription that lets you access more templates and discounts.

The Cricut StickerPix Print and Print + Cut machines are available now, starting at $169 and $299, respectively. Both machines come bundled with sticker sheets, photo paper and an ink cartridge.

Goose by The Robot Works Arrives as a Household Robot Built to Grow

Published

on

The Robot Works AI Goose Robot Household
Rolling down a hallway with a shirt slung over its neck, Goose looks less like a factory demo and more like a small appliance that decided to grow a personality. Prototype 1 from San Francisco’s The Robot Works is a white, low, rounded base with a long articulated neck, camera eyes set in a bonnet so you can see where it is looking, and a bright orange beak that doubles as a gripper. A blue polka-dot wrap gives the machine a costume instead of a chassis. Founders posted the first public clip this week with a simple brief: tidy, play, live.



Richard Wei has spent months sitting down with families to discuss what they really need from a robot in their house, and the team has used that information to create something they would like to have themselves. Humphrey Hu, who formerly worked with Anki on making highly expressive robot faces, will join him on this project. After considering all of the jobs that tend to build up around the house, as well as how a machine might interact with children and grandparents, they decided against a human-shaped body. Instead, the design features a wide stance close to the floor to keep the creature low to the ground, as well as a long neck that allows it to reach for items such as a sock, a wall outlet, a door handle, or a pile of laundry without having to stand on two legs and tower over the space.

They also kept the hardware minimal on purpose, resulting in a robot that rolls, looks around, and then moves on to complete its job. It analyzes its blind spots before moving, and the motors are meant to give way if something like a foot, a chair, or a child gets in the way, and the ability to halt and send it somewhere else was purposefully built in, so it wasn’t an afterthought. A video released shows the robot performing things like placing a man’s foot onto an ottoman, gathering clothes off the hardwood floor, reaching up to a kitchen counter, inserting a plug into a wall outlet, and even pulling open a door when some relatives arrive with children.

The Robot Works AI Goose Robot Household
Some early write-ups also highlighted some low-key jobs for older individuals who may be less mobile, such as fetching something you’ve tagged, bringing a walker over to the bedside when it’s time for bed, lighting the route to the toilet, keeping an eye out for falls, and sending a ping to family members. Some early elevator and door operations still need a human on the other end of the line, but on the positive side, autonomy is real in some areas and borrowed in others. Which is reasonable for the first version of the product.

The Robot Works AI Goose Robot Household
The concept is for the robot’s capabilities to evolve as a library rather than coming with a predefined set of talents when you buy it, and they intend to vet each new software before it is released, allowing you to choose what it can see and do. The company is now selling services such as a full-room tidy, checking in on Grandpa, being a companion during story time, taking a look around the house while you’re away, checking the stove, and bringing a parcel inside. The pitch is that life evolves, thus the machine should be able to continually adding new jobs to its repertoire rather of becoming locked in one specific role. That’s the whole point of “built to grow.” They also claim that any household data will remain under your control, rather than being a default action that occurs automatically when the robot arrives.

The Robot Works AI Goose Robot Household
Unfortunately, orders are currently closed because the initial prototype is still pre-production, with no price or commercial warranty available. Wei says the company is looking for “foster families” that will let Goose learn on real floors, real clutter, and real schedules. You can contact them at therobotworks.ai, while more information will be provided as the device gets closer to launch.

Hongqi N701 Travels With Xi Jinping From Hong Kong to the Trump Summit

Published

on

China Presidential Limo Hongqi N701 Beast
Chinese President Xi Jinping arrived in Washington this week for talks with President Donald Trump in the same custom state limousine that has followed him on foreign trips since 2022. Hongqi N701 is an internal project code more than a dealer name, and FAW Group’s Hongqi division built it for China’s top leadership rather than any public buyer. Hongqi means red flag, a name the brand has carried since 1958, when First Automobile Works first assembled luxury cars for senior officials.



Public sightings of the mysterious sedan began in July 2022, when Xi visited Hong Kong for the 25th handover anniversary. Since then, the long sedan has appeared in Russia, Egypt, and San Francisco last year, New Delhi for the BRICS summit a few weeks ago, and most recently in Washington. These trucks, you know, the ones who drive the leader about, frequently arrive ahead of the big cheese, often with black covers draped around a flatbed so all you see is fabric instead of the spaces between the panels. Surprisingly, manufacturing is carefully controlled; they reportedly only make approximately 50 of them per decade, or five per year, on a budget of around 572 million yuan ($85.2 million).

It’s 5.5 meters long, or around 18 feet, and has a large towering vertical chrome grille that reminds me of the Hongqi H9 sedan. There is also a red flag insignia slapped on the hood. Smaller flag poles sit on the front tire arches, and the side windows extend far back from the B-pillars, giving the second row passengers more freedom to move around, making it feel more like a genuine cabin back there. The back appearance is rather basic, with only some rectangular lights, some chrome on the tailgate, and two large exhaust pipes. Unfortunately, the actual weight, engine, and any armor plating specifications remain top secret. According to insider reports, it weighs more than 3 tons and features a large V8 or 6.0-liter V12 engine with 400 horsepower, as well as 21-inch run-flat wheels and some rather strong bullet-proof glass. It also appears to feature a separate air filtration system and a sealed cabin, as well as an encrypted link back to Beijing, but none of this has been confirmed by FAW.

Joe Biden caught a glimpse of it three years ago in San Francisco. He described it as a real beauty, and Xi was quick to point out that it was manufactured in China, before opening the rear door to allow Biden to look inside. Biden compared it to the American Cadillac, and now Washington can see the similarity up close. The Cadillac One, or the Beast, is built on a heavy truck chassis and is expected to weigh between 7 and 9 tons. The Hongqi N701 has the proportions of a long luxury sedan, but both automobiles are meant to protect a head of state from small arms fire, bomb fragments, and chemical threats while also serving as a mobile office.

Mao Zedong began hammering on about a Chinese state car in the 1950s. The early CA72 and CA770 Hongqis made the rounds of parades and whatnot, but were later supplanted by imported limousines. However, Xi had different plans when he began flying Hongqi L5s to New Zealand in 2014, later upgrading to the N501 and now the N701. Each time one of these sedans travels abroad, it gets to see the open road, but the whole specification sheet remains locked away with the individuals who created it.

At Meta Connect, the company’s smart glasses were everywhere

Published

on

If there was one thing that was obvious this from Meta Connect this year, it’s that the social media giant is all-in on its burgeoning line of smart glasses.

Indeed, the glasses were pretty much everywhere at the annual event, where Meta shows off its newest hardware and AI products. Both Meta staff and the flocks of influencers who frequent the event seemed to arrive with the glasses glued to their faces. Most of the demos the company offered this week also involved the glasses.

I swiftly joined the bespectacled masses and found myself trying on pair after pair of Meta’s high-tech specs.

One of the more notable products I had an opportunity to demo were Meta’s new, still-unreleased, audio-only smart glasses. News of these glasses emerged not long after the company weathered accusations that it was selling “pervert glasses,” with critics alleging that its camera-equipped specs could be used for nefarious surveillance purposes.

Advertisement

The new glasses come equipped with six microphones, but no camera, and they have no native way to record your surroundings, which should go a long way toward easing privacy concerns. They are significantly lighter than any of the other smart glasses I’ve worn, and they were quite comfortable.

The Meta staffer I talked to emphasized the glasses’ entertainment and communication options: you can listen to music easily (they’re more comfortable than earbuds) and take phone calls without reaching for your phone.

The glasses will also integrate with Muse, Meta’s personal agentic system, which can carry out tasks on the user’s behalf. The new integration, which isn’t yet available to the public, lets wearers speak to Muse and give it commands verbally. Meta also plans to personalize the agent, letting users pick from an assortment of cute digital avatars that can represent the agent when it communicates with them.

I was given an opportunity to try this out, which was fun but also somewhat comical. You have to be very direct with the agent, and you can’t talk to anyone else at the same time or it will get confused. Problematically, I kept chatting intermittently with the Meta staffer who’d given me the glasses, and the agent kept thinking I was speaking to it, so it would talk over her.

Advertisement

Still, in the right context, it’s easy to see how this new integration could be incredibly useful. If you don’t mind being seen in public talking to your own sunglasses, you’ll be able to ask Muse to take care of various digital tasks for you, like sending emails or reciting to-do lists, and it will handle them while you’re out grocery shopping or having a beer. You can also ask the glasses anything, and like a mobile version of ChatGPT, they’ll spit out an answer. (I asked the glasses a question about World War II, and they gave me a succinct and historically accurate response.)

Finally, I also got to test-drive a second audio-only pair: Meta’s new glasses for the hearing impaired. Given that hearing loss affects many families (some 50 million Americans are said to have some level of hearing loss), this device, unlike a lot of other modern tech gadgets, serves a clear and practical purpose.

Image Credits:Lucas Ropek

I spoke briefly with a member of Meta’s research team who said the glasses had been in development for some five years, and he pointed out a price difference that could make them appealing: whereas a lot of hearing aids can run as high as $1,600, the glasses will sell for $150.

The experience of wearing these glasses was interesting. Meta had me put earplugs in before trying them on to simulate the hearing loss that the glasses are meant to help users overcome. Once the glasses were on, they seemed to amplify the voice of the person I was talking to. Users can switch the amplification from focused, which zeroes in on the person in front of them, to omnidirectional, which picks up sound from all around them, depending on how they want to experience their surroundings.

Mark Zuckerberg has made it clear that he believes smart glasses are the future, and it’s evident that his company is doing its best to fulfill that mandate. But smart glasses remain a niche that has yet to truly find its footing. What was most obvious at Connect is that Meta has — in an attempt to succeed where others have failed — cast a very wide net, trying to make its glasses stylish, functional, and, most of all, useful.

Is this the future? Unsurprisingly, everyone at Connect seemed to think so. I suppose we’ll have to see if the rest of the world follows suit.

New Mexico Jury Rules Meta Misled State Residents About Data Privacy

Published

on

The company is still paying for the Cambridge Analytica scandal.

A New Mexico jury has found Meta violated the state’s Unfair Practices Act and misled residents about their privacy and how the company handles misinformation, Reuters reports. The trial was the result of a 2021 lawsuit filed by the state in response to Meta’s Cambridge Analytica scandal, in which data harvested from Facebook was used to target political advertising during the 2016 election.

The state’s original lawsuit claimed that Meta misrepresented what it let third-party apps do with its data, maintained privacy settings that were unclear or vague and falsely said it applied policies around hate speech equally to everyone, among other issues. Reuters writes that Meta’s lawyers admitted the company had made mistakes with how it handled misinformation and privacy in the past, but denied it sold users’ data or that it benefited from hate speech.

A judge has yet to rule how much Meta will be fined. Engadget has asked the company to comment on the case and the jury’s decision. We’ll update this article if we hear back.

Cambridge Analytica scraping and using information from 50 million Facebook users largely without their consent is one of several black marks on Meta’s resume, one it conveniently distanced itself from by rebranding to Meta in 2021. The company has reached multiple settlement agreements in response to Cambridge Analytica in the US, UK and Australia. Most recently, it settled with 47 US states over child safety concerns in an $18 billion settlement that included a $459 million payment to specifically resolve existing Cambridge Analytica lawsuits, Reuters writes. New Mexico and Florida declined to participate in that part of the settlement, which allowed this trial to happen and a jury to ultimately side against Meta again.

Tesla’s Semi finally enters production, nine years after it was shown

Published

on

Tesla has begun volume production of the Semi at Gigafactory Nevada with first deliveries this week, nine years after showing the truck, and rates it at 500 miles of range and 1.2 megawatts of charging. It has already installed more than 100 megawatt-capable stalls at 21 European sites, although the truck is not due in Europe until 2027.

Tesla has started volume production of the Semi at Gigafactory Nevada, with the first deliveries this week, InsideEVs reported. The Class 8 truck was first shown in 2017, nine years ago. It charges at up to 1.2 megawatts, which Tesla says adds 60% of range in 30 minutes.

The range comes with conditions.

Tesla rates the Long Range at 500 miles and the Standard Range at 325, both at 1.7 kWh per mile, and publishes the conditions alongside them. They are measured at 82,000 pounds gross, 55 miles an hour, 20 degrees Celsius, on flat ground, with a tandem axle aero kit and a compliant dry van trailer. Drive power is up to 800 kW from three motors.

Europe waits until 2027.

Tesla is installing more than 100 megawatt-capable stalls across 21 European sites in Germany, France, Britain, Sweden and the Benelux countries. The truck itself is not due here until next year. Both truck and charger use the MCS 3.2 connector.

European law asks for less.

Charging points of at least 350 kW must sit every 60 km along the core European network for heavy goods vehicles, as the ICCT has documented. The megawatt layer above that is commercial rather than required. Tesla built it before it had a truck to sell here.

Advertisement

The battery figures are not Tesla’s.

A filing with the California Air Resources Board gives 822 kWh of usable capacity for the Long Range and 548 kWh for the Standard, neither of which Tesla has published. The Semi uses Tesla’s own 4680 cells from Gigafactory Texas. Those cells have underperformed supplier cells in its passenger cars.

The biggest buyer is Swedish.

Einride ordered 500 Semis last month, the largest deployment announced anywhere, to run freight in California, Texas, New Jersey, Illinois and Georgia. A Swedish company is putting American trucks on American roads. Amazon holds warrants over about 12% of it.

Diesel is doing the selling.

Pump prices are averaging over $6.50 a gallon in the United States, a record driven by the wars in Ukraine and Iran. A coalition of shipping companies ordered 2,500 Semis this week, which would roughly double the American electric truck fleet. Tesla wants 50,000 a year once Nevada is at full capacity.

Pi Pico Recreates The Heathkit Pocket Packet

Published

on

Packet radio is a particularly fun part of the ham radio hobby. Once upon a time, you might have squirted data about the airwaves using something like the Heathkit HK-21 Pocket Packet. Heathkit stopped being a going concern some time ago, but [btech] has now recreated the device with modern hardware.

[btech] has called the project the Pocket Pico, and like the hardware that inspired it, it acts as a terminal node controller for amateur packet radio. It literally runs the same firmware as the real HK-21. It achieves this by using the Raspberry Pi Pico to run a Z80 processor emulator that can run the same code, while also using the microcontroller to do the work of modulating and demodulating Bell 202 audio tones at 1200 baud to avoid the need for a dedicated modem chip.

Thanks to running the same firmware as the HK-21, you can use the Pocket Pico with lots of old packet radio software. It’s fully capable of doing APRS as well as AX.25 Level 2, and has a built in Personal Bulletin Board System for other stations to leave messages.

If you’re looking to get into packet radio, you might just find this project to be useful. Alternatively, you might like taking a look at some other projects we’ve featured in this space, like the capable OpenModem project. Video after the break.
