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.

So, maybe right now isn’t the best time to get into the high-altitude ballooning hobby? At least in the US, which with the downing of another — whatever? — over Alaska, seems to have taken a “Sidewinders first, threat identification later” approach to anything that floats by. The latest incident involved an aircraft of unknown type, described as “the size of a small car” — there’s that units problem again — that was operating over Prudhoe Bay off the northern coast of Alaska. The reason that was given for this one earning a Sidewinder was that it was operating much lower than the balloon from last week, only about 40,000 feet, which is well within the ceiling of commercial aviation. It was also over sea ice at the time of the shootdown, making the chance of bothering anyone besides a polar bear unlikely. We’re not taking any political position on this whole thing, but there certainly are engineering and technical aspects of these shootdowns that are pretty interesting, as well as the aforementioned potential for liability if your HAB goes astray. Nobody ever really benefits from having an international incident on their resume, after all.

The Sidewinder line was a series of gaming peripherals produced by Microsoft, starting in the 1990s. After some initial stumbles, several cutting edge joysticks were released, at a time when the home computer market was in a state of flux, transitioning from legacy interfaces like serial and parallel to the more modern USB. In this interim period, Sidewinder joysticks used a special method to communicate digitally over the game port interface, which more typically used a kludge to read joysticks in an analog manner. [MaZderMind] managed to reverse engineer this protocol, and implemented the interface on an AVR microcontroller.
The technology is loosely described in US Patent 5628686, which discusses the method used to communicate bidirectionally with the Sidewinder joystick. [MaZderMind] found that the patent documents didn’t correspond exactly with how the Sidewinder Precision Pro communicated, but it was close enough that the operation could be reverse engineered.
The plan is to use the vintage joystick to control a quadcopter, so the interface was implemented on an AVR, and a graphical LCD installed to act as a display for testing the operation. [MaZderMind] also captured data on an oscilloscope to indicate in detail the quirks of the joystick’s operation.
Yes, it’s entirely possible to use a more modern microcontroller with a USB joystick. However, there are few that measure up to the standards of the old Sidewinder hardware, and sometimes the best tool for the job is the one you’ve got with you. A traditional single joystick is a different take on quadcopter control, but there’s other options – gesture control is possible, too.
