San Francisco Sues To Keep Autonomous Cars Out Of The City

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

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?

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?

Turning A 1:150 Scale Model Car Into A Real Driving Car With Lights

For many people having a miniature version of something like a car is already a miracle in itself, but there’s always the possibility to take matters a bit further, as YouTube channels like [diorama111] demonstrate. In this particular case, they took a 1:150 scale model of a Nissan Micra and installed a microcontroller, battery, remote steering and front, rear and indicator lights. Considering the 24.5 x 11.4 x 10.5 mm (LxWxH) size of the scale model, this is no small feat.

The original plastic bottom and wheels are removed, and replaced with a metal frame, as well as steerable front wheels that have a neodymium magnet attached to follow a metal guidance track that can be underneath the road surface. For the brains an ATtiny1616 MCU in QFN format is used to receive commands from the PIC79603 infrared receiver module and drive the motor attached to the rear axle via a DRV8210 motor controller IC. The remaining MCU pins are mostly used for turning the LEDs on the lights and signals on or off.

In the video the miniscule RC car is driven around a course with traffic lights, which gives a good impression of how this could be used in a large scale model of a city, with a hidden rail system to determine car routes. As for keeping the 30 mAh Li-Po battery charged, there’s a charge port on the bottom, but at these low current rates you could have hidden conductive charging points throughout the route as well, assuming you can fit a small enough charging coil in this little space.

Predicting The A-Bomb: The Cartmill Affair

The cover of the infamous issue of Astounding, March 1944

There’s an upcoming movie, Argylle, about an author whose spy novels are a little too accurate, and she becomes a target of a real-life spy game. We haven’t seen the movie, but it made us think of a similar espionage caper from 1944 involving science fiction author Cleve Cartmill. The whole thing played out in the pages of Astounding magazine (now Analog) and involved several other science fiction luminaries ranging from John W. Campbell to Isaac Asimov. It is a great story about how science is — well, science — and no amount of secrecy or legislation can hide it.

In 1943, Cartmill queried Campbell about the possibility of a story that would be known as “Deadline.” It wasn’t his first story, nor would it be his last. But it nearly put him in a Federal prison. Why?  The story dealt with an atomic bomb.

Nothing New

By itself, that’s probably not a big deal. H.G. Wells wrote “The World Set Free” in 1914, where he predicted nuclear weapons. But in 1914, it wasn’t clear how that would work exactly. Wells mentioned “uranium and thorium” and wrote a reasonable account of the destructive power: Continue reading “Predicting The A-Bomb: The Cartmill Affair”

Wiring An SD Card To A Handspring PDA’s 68K Bus With Only Three SOT23s

In 1998 the founders of Palm had a bit of a falling out with the wildly successful PDA company’s new owners. They set up a new company called Handspring, which enabled them to make PDAs again in the way they preferred, This resulted in the Handspring Visor line of PDAs, which featured a big cartridge slot called the Springboard Expansion slot. Much like a Gameboy, you could put in a range of modules, ranging from games to cameras to memory expansion and more. Since these modules connect directly to the internal Motorola 68k-based microprocessor, you could make a module either to comply with this standard or if you’re like [Dmitry], you’d figure out a way to get an SPI device like an SD card to communicate and expand storage.

Editor note: Dmitry’s design isn’t the first SD/MMC interface for the Visor. Portable Innovation Technology’s SD MemPlug Module supported SD/MMC way back in 2002. However – MemPlug was a commercial product, while Dmitry’s work is open source.

A Dashboard Outside The Car

One of the biggest upsides of open communications standards such as CAN or SPI is that a whole world of vehicle hacking becomes available, from simple projects like adding sensors or computers to a car or even building a complete engine control unit from the ground up. The reverse is true as well; sensors and gauges using one of these protocols can be removed from a car and put to work in other projects. That’s the idea that [John] had when he set about using a vehicle’s dashboard as a information cluster for his home.

The core of the build is an Astra GTE dashboard cluster, removed from its host vehicle, and wired to an Arduino-compatible board, in this case an ESP32. The code that [John] wrote bit-bangs an SPI bus and after some probing is able to address all of the instrument gauges on the dashboard. For his own use at home, he’s also configured it to work with Home Assistant, where each of the gauges is configured to represent something his home automation system is monitoring using a bit mask to send data to specific dials.

While this specific gauge cluster has a lot of vehicle-specific instrumentation and needs a legend or good memory to tie into a home automation system without any other modification, plenty of vehicle gauges are more intuitive and as long as they have SPI they’d be perfect targets for builds that use this underlying software. This project takes a similar tack and repurposes a few analog voltmeters for home automation, adding a paper background to the meters to make them easier to read.
