Why Stealing A Car With Flipper Zero Is A Silly Idea

February 15, 2024 by 27 Comments

In another regular installment of politicians making ridiculous statements about technology, Canada’s Minister of Innovation, Science and Industry, [François-Philippe Champagne], suggested banning Flipper Zero and similar devices from sale in the country, while accusing them of being used for ‘stealing cars’ and similar. This didn’t sit right with [Peter Fairlie] who put together a comprehensive overview video of how car thieves really steal cars. Perhaps unsurprisingly, the main method is CAN bus injection, for which a Flipper Zero is actually a terribly clumsy device. Rather you’d use a custom piece of kit that automates the process.

You can also find these devices being sold all over the internet as so-called ‘Emergency Start’ devices for sale all over the internet, all of which use weaknesses in the car’s CAN bus network. The common problem appears to be that with these days even the lights on the car being part of the CAN network, an attacker can gain access for injection purposes. This way no key fob is needed, and the ignition system can be triggered with the usual safeties and lockouts being circumvented.

Ultimately, although the Flipper Zero is a rather cutesy toy, it doesn’t do anything that cannot be done cheaper and more effectively by anyone with a bit of CAN bus knowledge and a disregard for the law.

How Much Longer Will Cars Have Cigarette Lighter Ports?

February 1, 2024 by 101 Comments

Depending on the age of your car, it might contain a round 12 V power outlet in the dash, or possibly in the elbow compartment. And depending on your own age, you might know that as the cigarette lighter port. Whereas this thing used to have a single purpose — lighting cigars and cigarettes via hot coil — there are myriad uses today, from charging a phone to powering a dash camera to running one of those tire-inflating machines in a roadside emergency.

But how did it come to be a power source inside the vehicle? And how long will it stick around? With smoking on the decline for several decades, fewer and fewer people have the need for a cigarette lighter than do, say, a way to charge their phone. How long will the power source survive in this configuration?

Cheap Hack Gets PCI-X Card Working In PCI Slot

February 1, 2024 by 10 Comments

PCI and PCI-X are not directly compatible, and you’d be forgiven for thinking that means you’re out of luck if you need to use a PCI-X card in a machine that only has basic PCI slots. And yet, that needn’t be the case. As [Peter] shows us, you can work around this with a cheap hacky hack. Our favorite kind!

[Peter] had a PCI-X RAID card that he wanted to use on his Socket 7-based computer. The 3ware 9550SX PCI-X card is 3.3 V only, and doesn’t fit in a typical PCI slot. It’s not compatible mechanically or electrically. Enter a PCI-X riser, which gets around the missing notch that would normally not let the card sit in the slot. Other than that, it just took masking off some pins to avoid damage from the 5 V rail. Throughput is good, too, reportedly sitting at roughly 60-70 MB/s.

The hard part is probably finding a PCI-X riser; PCI-Express stuff is far more common. Few of us need to deal with PCI-X anymore, but if you’re working on some ancient industrial hardware or something, this hack might just save your beans from the roast pot one day.

Ground-Effect Vehicle To Carry Passengers Around Hawaii

January 27, 2024 by 29 Comments

Although Hawaii used to have a ferry service to access the various islands in the archipelago, due to environmental and political issues, air travel is now the only way to island-hop. Various companies have tried to fill this transportation gap, but have all been stymied for one reason or another. The latest to attempt to solve this problem is a unique one, however. The Hawaii Seaglider Initiative is currently testing a ground-effect vehicle for inter-island passenger service that hopes to use the unique characteristics of this type of aircraft to reduce costs and limit environmental concerns.

The Seaglider, with backing from the Hawaii state government and various corporate interests like Hawaiian Airlines, is actually an amalgamation of three different types of vehicle. It’s capable of operating like a normal, hulled boat at low speeds but has a hydrofoil for operating at higher speeds. Beyond that, its wings give it enough lift to leave the water but stay in ground-effect flight, flying low to the water to reduce drag and improve lift when compared to an aircraft flying out of the ground effect. The efficiency gains from this type of flight are enough that the Seaglider can use electric motors and batteries to make the trips from island to island.

While the ferry is not yet in service, flight testing of the vehicle is scheduled for this year. Ground-effect vehicles of this type do have a large number of obstacles to overcome, whether they’re huge military vehicles like the Ekranoplanes of the Soviet Union or even small remote-controlled crafts, including difficulty with rough seas and having to operate in a harsh salt water environment.

San Francisco Sues To Keep Autonomous Cars Out Of The City

January 26, 2024 by 32 Comments

Although the arrival of self-driving cars and taxis in particular seems to be eternally ‘just around the corner’ for most of us, in an increasing number of places around the world they’re already operational, with Waymo being quite prevalent in the US. Yet despite approval by the relevant authorities, the city of San Francisco has opted to sue the state commission that approved Google’s Waymo and GM’s Cruise. Their goal? To banish these services from the streets of SF, ideally forever.

Whether they will succeed in this seems highly doubtful. Although Cruise has lost its license to operate in California after a recent fatal accident, Waymo’s track record is actually quite good. Using public information sources, there’s a case to be made that Waymo cars are significantly safer to be in or around than those driven by human operators. When contrasted with Cruise’s troubled performance, it would seem that the problem with self-driving cars isn’t so much the technology as it is the safety culture of the company around it.

Yet despite Waymo’s better-than-humans safety record, it is regarded as a ‘nuisance’, leading some to sabotage the cars. The more reasonable take would seem to be that although technology is not mature yet, it has the overwhelming advantage over human drivers that it never drives distracted or intoxicated, and can be deterministically improved and tweaked across all cars based on experiences.

These considerations have been taken into account by the state commission that has approved Waymo operating in SF, which is why legal experts note that SF case’s chances are very slim based on the available evidence.

The NSA’s Furby Artificial Intelligence Scare: FOIA Documents Provide Insight

January 25, 2024 by 21 Comments

For those of us who were paying a modicum of attention to the part of the news around 1999 which did not involve the imminent demise of humanity due to the Y2K issue, a certain toy called a ‘Furby’ was making the headlines. In addition to driving parents batty, it also gave everyone’s favorite US three-letter agency a scare, with it being accused of being both a spying tool and equipped with an advanced artificial intelligence chip. Courtesy of a recent Freedom of Information Act (FOIA) request we now have the low-down on what had the NSA all atwitter.

In a Twitter thread (Nitter) user [dakotathekat] announced the release, which finally answered many questions about the NSA’s on-premises ban of Furbys (or Furbees if you’re Swedish). The impression one gets is that this ‘Furby ban’ was primarily instated out of an abundance of caution, as unauthorized recording devices of any kind are strictly forbidden on NSA premises. With nobody at the NSA apparently interested in doing a teardown of a Furby to ascertain its internals, and the careful balance between allowing children’s toys on NSA grounds versus the risk of a ‘Furbygate’, a ban seemed the easy way out. Similarly, the FAA saw fit to also make people turn their Furbys off like all other electronic devices.

The original Furby toys did not have anything more complex inside of them than a 6502-derived MCU and a Ti TSP50C04 IC for speech synthesis duties, with the supposed ‘learning’ process using a hardcoded vocabulary that gradually replaced its default gibberish with English or another target language.

Can Car Parts Grow On Trees?

Cars don’t grow on trees, but Ford is designing car parts from olive tree cuttings. [via Electrek]

Ford is no stranger to designing parts from plants for their vehicles. Henry famously liked to beat on the Soy Bean Car with a blunted axe to tout the benefits of bioplastic panels. Researchers at Ford’s Cologne, Germany facility have detailed their work to use waste from olive orchards as part of a new biocomposite from the LIVE COMPOLIVE program.

Fibers from the olive tree cuttings are mixed with recycled plastic and injection molded to form panels. The video below features interior panels that are currently made with traditional plastics that could be swapped over to the new composite. Since these cuttings are a waste product from food production, there isn’t the tension akin to that presented via biofuels vs food. We’re curious what Precious Plastics could do with this, especially if the fibers are able to reinforce the matrix.

If you want to see some other unusual uses for waste wood, why not checkout a “paper” bottle or 3D printing with sawdust?
