  • Magnetic-Suspension Hoverboard is Only 11 Years Late

    Anyone who saw Back to the Future II was disappointed when 2015 rolled around with nary a hoverboard in sight. There have been various attempts to fake it, but none of them quite have the feel of floating about wherever you’d like to go that the movie conveys. The little-known YouTuber [Colin Furze] has a new take on the idea: use magnets. Really big magnets.

    If you’re one of [Colin]’s handful of subscribers, then you probably saw his magnetic-suspension bike. We passed on that one, but we couldn’t resist the urge to cover the hoverboard version, regardless of how popular [Colin] might be on YouTube. It’s actually stupidly simple: the suspension is provided by the repulsive force between alarmingly large neodymium magnets. In this case, two are on the base plate that holds the skateboard ‘trucks’, and two are on the wooden ‘deck’ that [Colin] rides upon.

    Of course magnetic repulsion is a very unstable equilibrium, so [Colin] had to reduce the degrees of freedom. In his first test, that was with a pair of rods and linear bearings. That way the deck could only move in the z-axis, providing the sensation of hovering without allowing the deck to slide off its magnetic perch. Unfortunately those pins transferred too much vibration from the ground into the deck, ruining the illusion of floating on air.

    After realizing that he’d never be able to ollie (jump) this massive beast of a skateboard, [Colin] decides he might as well use a longboard instead. Longboards, as the name implies, are long skateboards, and are for transportation, not tricks. The longboard gets the same massive magnets, but after a couple of iterations to find a smoother solution — including a neat but unsuccessful tensegrity-inspired version — ends up with a pair of loosely-fitted pins once again, though relocated to the rear of the board. From the rider’s perspective, it looks exactly like a hoverboard, since you can’t see underneath from that angle. According to [Colin], it feels like a hoverboard, too.

    The only way to do better would be with eddy currents over copper, or superconductors over a magnetic track, but both of those methods limit you to very specific locations. This might be a bit of a fakeout, but its one with a degree of freedom. One, to be specific. You have to admit, it’s still less of a fake than the handle-less Segway we got in 2015, at least.

  • @geeknik Yup. It was a honeypot. All this time.

    And bombs will drop according to that location data some day.

    Friend of mine came back from the Netherlands after visiting family, & told me about a meeting he sat in on with some of wife's colleagues & their management. Friend was boggling at how colleagues were just taking the •piss• out of mgmt for some stupid decision.

    My immediate thought: "That's socialized healthcare for you."

    ChaosBSD: a FreeBSD fork to serve as a driver testing groundChaosBSD is a fork of FreeBSD. It exists because upstream cannot, and should not, accept broken drivers, half-working hardware, vendor trash, or speculative hacks.We can.↫ ChaosBSD GitHub pageThis is an excellent approach to testing drivers that simply aren't even remotely ready to be included in FreeBSD-prohttps://www.osnews.com/story/144210/chaosbsd-a-freebsd-fork-to-serve-as-a-driver-testing-ground/#FreeBSD

    @EuroBSDCon was a blast as always. The amount of work put in by the organisers is incredible, and both the local crew (Karlo and friends, you've been a great help and I owe you an audio cable!) and the video gang (@mischa@exquisite.social, your camera saved the day .. reluctantly; @dexter and the rest of the @bsdtv gang y'all gonna need better dongles ;) bent over backwards to accommodate my somewhat eccentric needs. If anyone is interested in what I had to say (and hand out) during my talk, the QR code at the end leads to http://anduin.net/l.htm - go grab your copy in any of three formats: Bootable floppy, zipped TheDraw files, or PDF (boo!).I met too many awesome people to count, much less remember the names of everyone, but I truly hope those of you who want to reach out will do so. My DMs are open ;)The social overload from this weekend will quickly turn into the pain of missing the company of this extended family. Can't wait to see you again in Brussels - or at any time before that if you visit Oslo!#EuroBSDCon #EuroBSDCon2025 #EuroBSDCon2026 #RunBSD #NetBSD #OpenBSD #FreeBSD #BSD
