The internet only just got over Lexus’ real working hover board, but as it turns out, a team of researchers from the University of Paris Diderot already built one, over 4 years ago (machine translation)!
Using the same principles as the hover board Lexus build, the researchers built a very expensive neodymium magnet track to test the board on. Only difference here is that they didn’t hide the magnets. The hover board itself was machined out of wood, and houses a large sealed metal tray which contains the superconducting bricks.
Pour in some liquid nitrogen through the funnel, and you’re ready to witness some of the quantum properties of superconductors! The board floats a few centimeters above the magnetic rails, and in their tests was able to lift people over 100 kg in weight (hint for most Americans… there are 2.2 pounds to one kilogram).

To be honest, we were wondering when we would see someone try this…
[Ryan Craven] has successfully built a working hovercraft that looks like a skateboard. It floats on two pockets of air generated by four Black and Decker leaf blowers — and by golly, it certainly looks like it works!
Ever since the HUVr hoax earlier this year, [Ryan] has had the goal to make a real, working hoverboard. Hendo may have beaten him to the punch with their $10,000 eddy current inducing halbach array board, but alas, it only works on copper or aluminum floors. [Ryan’s] can be used anywhere a normal skateboard can be. It’s far from sleek, but it’s only just the prototype — though we’re curious to see how far this could actually go.
Which is precisely why he’s shared it over on Hackaday.io and is hoping to draw some support and ideas from our wonderful community here.
What do you guys think? Is it worth continuing the pursuit of a hovercraft style hoverboard? Can we shrink the technology enough to make it feasible? It’s come a long way from the classic hover craft using a giant shop vac…

Okay now this is seriously awesome. [Rodger Cleye] has made a real working Hoverboard.
You guys might remember the recent [Tony Hawk] and [Christopher Lloyd] viral Hoverboard hoax video… Well, this isn’t that. Nope, not even close. It’s real.
The Hoverboard is a quadrotor on steroids — it features four 1200W brushless motors driving 12″ props, a massive 13.4Ah 5S Li-Po battery, and a [Marty McFly] mannequin wearing the classic red vest. He’s counter-balanced [Marty] and the battery around the rotors which makes for a surprisingly smooth flight. It even has a run-time of over 5 minutes, thanks to a whopping 83% efficiency using the 12″ props.
[Rodger] designed and simulated the entire system in eCalc before construction — He had first attempted a bi-copter design, but opted for the tried and true quad-rotor instead. The frame is made of 1/2″ PVC pipe to conserve the mass budget, but altogether it still weighs an unbelievable 20lbs! How close are we to being able to give toddlers the ability to fly?
Just take a look at the following video — we’re seriously impressed.
