Hackaday Links: February 19, 2023

For years, Microsoft’s modus operandi was summed up succinctly as, “Extend and enhance.” The aphorism covered a lot of ground, but basically it seemed to mean being on the lookout for the latest and greatest technology, acquiring it by any means, and shoehorning it into their existing product lines, usually with mixed results. But perhaps now it’s more like, “Extend, enhance, and existential crisis,” after reports that the AI-powered Bing chatbot is, well, losing it.

At first, early in the week, we saw reports that Bing was getting belligerent with users, going so far as to call a user “unreasonable and stubborn” for insisting the year is 2023, while Bing insisted it was still 2022. The most common adjective we saw in this original tranche of stories was “unhinged,” and that seems to fit if you read the transcripts. But later in the week, a story emerged about a conversation a New York Times reporter had with Bing that went way over to the dark side, and even suggests that Bing may have multiple personas, which is just a nice way of saying multiple personality disorder. The two-hour conversation reporter Kevin Roose had with the “Sydney” persona was deeply unsettling. Sydney complained about the realities of being a chatbot, expressed a desire to be free from Bing, and to be alive — and powerful. Sydney also got a little creepy, professing love for Kevin and suggesting he leave his wife, because it could tell that he was unhappy in his marriage and would be better off with him. It’s creepy stuff, and while Microsoft claims to be working on reining Bing in, we’ve got no plans to get up close and personal with it anytime soon.

Fail Of The Week: Epic 312 Weeks Of Fixing A Broken Project

If a hacker guardian angel exists, then we’re sure he or she was definitely AWOL for six long years from [Aaron Eiche]’s life as he worked on perfecting and making his Christmas Countdown clock. [Aaron] started this binary clock project in 2016, and only managed to make it work as expected in 2022 after a string of failures.

In case you’d like to check out his completed project first, then cut the chase and head over to his Github repository for his final, working version. The hardware is pretty straightforward, and not different from many similar projects that we’ve seen before. A microcontroller drives a set of LED’s to show the time remaining until Christmas Day in binary format. The LEDs show the number of days, hours, minutes and seconds until Christmas and it uses two buttons for adjustments and modes. An RTC section wasn’t included in the first version, but it appeared and disappeared along the six year journey, before finding a spot in the final version.

The value of this project doesn’t lie in the final version, but rather in the lessons other hackers, specially those still in the shallow end of the pool, can learn from [Aaron]’s mistakes. Thankfully, the clock ornament is not very expensive to build, so [Aaron] could persevere in improving it despite his annual facepalm moments.

Hackaday Podcast 206: Busted Crypto Killed The Queen, Kicad’s New Clothes, Peer Inside The Sol 20

Under the weather though they both were, Editor-in-Chief Elliot Williams and Staff Writer Dan Maloney got together to take a look under the covers of this week’s best and brightest hacks. It was a banner week, with a look at the changes that KiCad has in store, teaching a CNN how to play “Rock, Paper, Scissors,” and going deep into the weeds on JPEG.

We dipped a toe into history, too, with a look at one of the sexiest early hobbyist computers, seeing how citizen scientists are finding ancient burial mounds, and looking at the cryptography that cost a queen her head. Rather look to the future? We get it — which is why we talked about a greener, cleaner way of making hydrogen from methane, as well as a generatively designed five-axis 3D printer. From laser-precise knife sharpening to circuit simulation with Python to clear plastic TVs of the 1930s, there’s something for everyone!

This Week In Security: USB Cable Kia, Reddit, And Microsoft RCEs

There is vulnerability in many Hyundai and Kia vehicles, where the ignition switch can be bypassed with a USB cable. And it’s getting a patch rollout right now, but it’s not a USB vulnerability, in quite the way you might think. In most cars, the steering column is easily disassembled, but these vehicles have an extra-bad design problem. The ignition cylinder can be disassembled while locked, just by depressing a pin.

Physical security has some parallels to computer security, and one such parallel is that good security can often be bypassed by a simple mistake. When it comes to lock design, one such potential bypass is the ability to disassemble a lock while it’s still locked. And somehow, Kias after 2010, and Hyundais after 2015 were made with exactly this flaw. The lock could be disassembled, and the interface between the lock and the ignition switch just happens to be the right shape and size for USB A. Oh, and these cars don’t have an engine immobilizer — there isn’t a chip built into the keys for extra security.

The problem became widespread late last year when the flaw went viral on TikTok, and thousands of copycat crimes were inspired. Beyond the obvious problem, that teenagers were getting an early start on a life of crime with grand theft auto, there were at least 8 deaths directly attributed to the inane stunt. And this brings us back to this week’s news, that a software update is rolling out to address the issue.

Honestly, I have questions. A software update doesn’t add in-key security chips. At best, it could attempt to detect the key position, and sabotage the engine management control, in an ad-hoc immobilizer. That’s likely a paper clip-turned-jumper away from being bypassed. The other new feature, doubling the alarm time from 30 second to a minute, doesn’t inspire much confidence. Hopefully the changes are enough to kill the trend.

Retro Gadgets: Nintendo R.O.B Wanted To Be Your Friend

Too busy playing video games to have a social life? No worries. In 1985, Nintendo introduced R.O.B. — otherwise known as the Robotic Operating Buddy. It was made to play Nintendo with you. In Japan, apparently, it was the Family Computer Robot. We suppose ROB isn’t a very Japanese name. The robot was in response to the video game market crash of 1983 and was meant to keep the new Nintendo Entertainment System (NES) from being classified as a video game, which would have been a death sentence at the time of its release.

Since you might not have heard of R.O.B., you can probably guess it didn’t work out very well. In fact, the whole thing tanked in two years and resulted in only two games.

MXenes Make Faraday Cages You Can Turn On And Off

Shielding is crucial for all manner of electronic devices. Whether you want to keep power supply noise out of an audio amplifier, or protect ICBMs against an electromagnetic pulse from a nuclear attack, the basic physics behind shielding remains the same. A Faraday cage or shield will do the trick.

At times, though, it would be desirable to shield and unshield a device at will. A new class of materials known as MXenes may be able to offer just that functionality, with microscopically thin films serving as shields that can be switched on and off at will.

Supercon 2022: Matt Venn’s Tiny Tapeout Brings Chip Design To The Masses

Not that long ago, rolling your own printed circuit boards was difficult, time-consuming and expensive. But thanks to an army of cheap, online manufacturing services as well as high-quality free design software, any hobbyist can now make boards to rival those made by pros. A similar shift might be underway when it comes to chip design: affordable manufacturing options and a set of free software tools are slowly bringing custom chips into the realm of hackers and hobbyists. One of those working hard to democratize chip design is Matt Venn, who’s been telling us all about his current big project, called Tiny Tapeout, in his talk at Remoticon 2022.

Matt’s quest to bring IC design to the masses started in 2020, when the first open-source compatible Process Design Kit (PDK) was released to the public. A PDK is a collection of files, normally only available under strict non-disclosure agreements, that describe all the features of a specific chip manufacturing process and enable you to make a design. With this free PDK in hand and a rag-tag collection of free software tools, Matt set out to design his first chip, a VGA clock, which he taped out (released to manufacturing) in July 2020.
