Hackaday Links: September 10, 2023

Most of us probably have a vision of how “The Robots” will eventually rise up and deal humanity out of the game. We’ve all seen that movie, of course, and know exactly what will happen when SkyNet becomes self-aware. But for those of you thinking we’ll get off relatively easy with a quick nuclear armageddon, we’re sorry to bear the news that AI seems to have other plans for us, at least if this report of dodgy AI-generated mushroom foraging manuals is any indication. It seems that Amazon is filled with publications these days that do a pretty good job of looking like they’re written by human subject matter experts, but are actually written by ChatGPT or similar tools. That may not be such a big deal when the subject matter concerns stamp collecting or needlepoint, but when it concerns differentiating edible fungi from toxic ones, that’s a different matter. The classic example is the Death Cap mushroom (Amanita phalloides) which varies quite a bit in identifying characteristics like color and size, enough so that it’s often tough for expert mycologists to tell it apart from its edible cousins. Trouble is, when half a Death Cap contains enough toxin to kill an adult human, the margin for error is much narrower than what AI is likely to include in a foraging manual. So maybe that’s AI’s grand plan for humanity — just give us all really bad advice and let Darwin take care of the rest.

Smart Pants Sound Alarm When Your Fly Is Undone

It’s always embarrassing to be told your fly is down. Even moreso when you realize it’s been that way since you returned from the bathroom an hour ago. [Guy Dupont] has built a device to solve this awkward issue once and for all. (Nitter)

Pictured: The Hall effect sensor and magnet attached to the zipper.

The pants contain a Hall effect sensor which has been attached inside the fly of the jeans, at the bottom of the zipper. The zipper pull itself was then fitted with a strong magnet, which triggers the sensor when the zipper is in the open position. An ESP32 in the pocket of the jeans is tasked with monitoring the sensor. If it detects that the zipper has been down for too long, it sends a notification to the wearer’s smartphone to zip up. We kind of wish they’d sound an ear-splitting klaxon, but that might draw undesired attention to the wearer.

Zipper position monitoring seems like a nightmare at first, but [Guy]’s hack shows us that it’s actually trivial with this method. The system does, however, add significant complication to what was previously a totally-analog pair of pants. Don’t expect “Big Jeans” to jump on this tech, as maintenance and waterproofing issues would likely make the hardware a pain to deal with in real life.

Plus, just imagine the frustration every morning. “Sorry, mate, not ready to head out yet – I’ve gotta pair my jeans with my smartphone.”

Why Get Dressed When There Are Software Pants?

With so many of us working from home over the last two years, it’s really become apparent that people generally dislike sitting all day with pants on. Until such a utopian time when all clothing is considered unisex, and just as many men as women are kicking it in loose, flowing skirts and dresses, you may want to remember to actually wear something on your lower half, uncomfortable though pants may be. But there is another way — you could build [Everything Is Hacked]’s pants filter and continue to be a chaos agent. Check out the video after the break.

These pants go as wide as you please.

That’s right, whether you forego or just forget to dress yourself below the equator, the pants filter has you covered. It works like you might expect — machine learning tracks body landmarks and posture to figure out where your NSFW region is and keep it under wraps.

By default, it blurs everything below the belt, or you can draw on pants if you’re inclined to be in revealing tighty-whities and prefer more coverage. You can adjust the width of the pants to cover the covid-19 you may have put on since 2020, and even change the pants to match your shirt.

We love that [Everything Is Hacked] had the um, gumption to test the pants filter in public at what appears to be a local taco joint. After the first few rounds of weird looks, he switched to a pants moustache to save face.

Want to add even more fun to those boring video calls? Try connecting up some vintage hardware, or install a pull chain to end those sessions with a gesture that won’t get you fired.

Animatronic Winged Demon Terrorizes Local Garage

WingedDemonVideo005

Halloween is on its way, and if you’re going to do it right, you’re going to overdo it right. A few days ago we showed you [Jake’s] flying Crank Ghost, the idea is simple and creates lovely motion that is sure to scare some small children. But what if you want people leaving your little shop of horrors needing a new pair of pants? Meet the Animatronic Winged Demon by [Woody]. Very little info is given except for the touch screen controller, the central control system, and his unique use of a modular skeleton, but the project is very impressive none the less. If the demon doesn’t scare you, take a look at the miles of wires needed to control it. Check out a video after the break.

Keyboard Pants

kbpants

[Zach] sent us a link to his keyboard pants. Frankly, we were astonished, not only by his craftsmanship, but by the fact that we were working on a pair ourselves. Admittedly his are much better looking and ours will probably never be finished. The inspiration for both his and ours, was this sloppy version. [Zach’s] pair have been cut in half, and he never really found a convenient way to reconnect the two halves, so only the left works. Watch this video to see him playing some Tetris in his awesome shorts.
