ON THE HENDO HOVERBOARD: How it works and demonstration 

I just appreciate that you cut the audio down when the motor got loud.

_subscribed_ for hopefully many videos in this style. Efficient, educational, interesting, calm. Do more stuff like this.

At 0:07 it sounds like he says "Today we're gonna fuck with the Hendo Hoverboard."

Ha! This is awesome. I guess I'm not the only DIY enthusiast interested in knowing how it works... before finding your video, I did the exact same thing, and made a working hover-display exactly like yours. I read the patents, and made a 3d-printed housing for 40 small neodymium magnets (which I assume is how you made yours), and it worked! I might post a video soon. Also, from being in AP Physics C this year, Phys. B last year, I worked with the equations a bit, and I believe that the Halbach array is weaker... It's the mag-field change from magnet to magnet that induces the currents in the surface, so NS SN is a stronger change than the Halbach, cause it's the individual fields that make it work, not the overall. I doubt they actually use the Halbach anyway. I'm just really happy to see other makers out there with the same interests doing cool stuff! One question, what motor did you use? Mine was a cheap outrunner from amazon, 2200Kv, so it would considerably slow down when near the aluminum because of the Eddy Currents resisting the movement. Maybe it was going too fast... What was the brand, Kv, etc of your motor? Thanks for your time, this is awesome.

Wow. It's really interesting and amazing how we have been wondering for such a long time how it would be possible to hover completely off the ground, and how complex and advanced it would have to be. But, as demonstrated here, it's so simple.

I in fact just read the Wired article you mentioned and they have no idea how that thing works it thank you for making this video.

Excellent explanation of the tech, thanks.

Funny how Henderson never mentions where he got the idea for the lifters in the hoverboard. I wonder why?

OMG It is so simple, and has been staring us in the face for a while. Pretty cool!

Thanks for the video. Can you share where you got the circular disc that holds the magnets? Thanks

Could you post the STL file for the rotor you 3D printed? I would like to try it out for my self

Joshua Higuera Yep. This tech has been known for quite some time, and has been previously referred to as the Lenz effect. It will NOT work on any surface that is ferromagnetic and/or nonconductive.

Where did you get your motor setup and the magnet holder? I have to build a working hover board for a science project for school....

Awesome demo showing us how this cool "tech" works. I think it's a great idea because there are gonna be some very specialized applications that can benefit from powered frictionless levitation, but the main problem is that Lenz's law dissipates most of the rotational energy into heat on the conductive "riding surface" below. Not only that, but you have to have an even number of these "hover engines" rotating in opposing directions, just like a multirotor UAV, and when you place more weight above one of them, it causes the entire system to torque! (Tony Hawk demonstrated this near the end of that video) Software and sensor feedback can probably be used to offset this effect, and that further explains what they're doing inside the White Box Plus model to provide the 3 DOF control. I would wager they're going to rotate the individual hover engines slightly in order to gain rotational and translational driving, by having magnets ride closer to conductive surface along a suitable portion of their rotational path. Going back to the power properties, it's really kind of crappy because just like the multirotor props generate huge drag in the air, the rotating magnets generate huge drag in the eddy currents of the levitating riding surface, and there's no way to recover this energy. Maintaining a hovering can theoretically require no energy input (and indeed every item ever, placed upon a desk or any other place already excels at this), so I guess I could say that we still have our work cut out for us, but really, for a few specialized applications, the energy inefficient way to gain real multidimensional control is very worth it. Oh, also it's preposterous to think of levitating buildings (yes they mention this in the kickstarter video). That is not really very realistic (if just conceivably plausible) as it would require a nuclear power reactor in the building to drive it. I say this because no matter how strong you can make your electromagnets, with superconducting coils, an enormous amount of additional energy is still required as input to torque these magnets in opposing directions. That is, we still have the huge energy being deposited into the eddy current riding surface as unrecoverable heat.

does the magnetic lift increase as the RPM increases or does it have to spin at a minimum RPM and if you go higher then the lift will stay the same?

what is the blue thing holding the magnets and if anybody knows plz trll me where i can get one

What is the blue thing that you used in which the neodymium magnets are attached neodymium magnets??

what kind of motor can I use to match the rpm? does it have a heat sync?

RaptorTech If i do that, at least at low speed, aluminum engine would try to curb drastically, but in this case a repulsion appears, are due to the high speed you use and therefore a very high frequency? How many hertz are required to work?

Wher did you get that motor and where can you get bigger and better ones

where did u get the motor and aluminum?

Thats so cool! i would like to ask thougjh, why neodymiun magnets? can any one answer this, i would just like to know

Nicely explained.

What if you take the halback array and since one side is neutral instead of an electric motor you use slant ways Electromagnet creating an opposing feild inducing the spin just like the oppsing field repelling ferrous conductive metals? also I thought I had seen one of these hendos on concrete I understand their is Rea-bar in concrete, and concrete once in the past was non for draining batteries Am I wrong here is this technology to weak for concrete. Finally can you regulate height with rpm of the magnetic disk?

What kind of motor is it where can u buy it and how much is it

Very very nice demo

Where did you get the disc

Where did you buy the motor?

one question, which motor do you use?

If you juiced up the magnets then inserted strips of aluminum or copper or w/e non-ferrous metal is cheapest into streets/sidewalks/etc, would this work, outside of plating everything in metal, as a viable transportation device? Or does the amount of metal in the surface make a difference as to how hard it pushes back against the board?

What motor are you using

Where can I get a spinning motor like that?

Can someone tell me all of the materials in the video?

Could someone say me what type is that small motor please?? THNX!! :d

Can you give me the 3d design of the blue part

what kind of motor is this? Pls answer me quick!! Pls and thank you!

Simple yet efficient!

What's the word you said after the Hendo has nicer magnets after the demonstration? You said they have something called the ______ that holds heavier weight.

where can i get that kind of motor

Awesome video keep it up!!!!!

But does that magnetic feild work on any type of floor? On wooden? On tiles?PLZ REPLY

Really thanks for this.....!

Good demo, as explained in the patent what you've demonstrated here is a device that I invented back in 2009 as I demonstrated in an explanatory video on my channel. Cheers. -Scott A. Stevenson

Amazing stuff

how fast does it spin

could you do a video of the disc hovering over the metal?

why did you put the magnets in altering patterns ? does it work in S S S S or N N N N ? or do I need S N S N S N S N to generate eddy current ?

whats the name of the "disk" you refer to in this video?

Can you please make a tutorial about this?

How much did the build costs?

how strong are those magnets o.0 induction?

Is it possible to make a machine that would hover more than 3 meters? With a railroad like this of course

Raptor, Nice video but you missed the real advance in the organization of the flux: closed loop arrays that pattern the flux so that it is all useful... Greg

what kind of disc? does it have to be a specific kind of disc? or can you put the magnets in a donut?

Awesome!

question, how does it work on non-metal?

Hi! I hace a dude ... The metal of tour left , what is it ? Aluminium? Thanks!

Does freezing increase the lenz effect.

how did you make that

no wonder why it sounds so FUCKING AWSOME!!

I agree with all of you this has been around for some time. you may also notice that there are other things that may seem far fetched but have also been around. the tech is out there. if you want to build something build it work together, because a lot of you probably have better models and these guys all they do is just capitalize on it with low quality versions, and you guys know there are other higher quality versions being done in garages. Let's synergize

So its basically a maglev board?

Quiero un video en español por favor. ..esto es interesante

On the Avasva you can count on professional help with problems and technical support.

So does the ground that the board goes over have sheets of metal. I dont see what looks like a metal ground when I watch hendo videos. Somebody let me know.

i think most of the ppl who what the hendo video knows how it work but thanks for sharing your info

Also, if you simply get a common magnet n' get it closer to a piece of metal it will either repel or attract it.

Is more force created at higher rpms?

Why you dont take a motor and magnits from HDD? You can get 10000rpm motor and strong inofe magnits...

That's funny I thought of this a couple weeks ago.

I have to ask, so they never did come up with a new idea this was already technology known to man, also this tech can only be used over certain metals not like out on a regular sidewalk? ...

It’s funny how the company just failed and they did that kickstarter for the white box…but no one really tore down the white box to see what they did.

thank

The magnetic hoverboard works very well...just you need roads made out of copper or aluminum instead of asphalt

water is technically a little bit conductive... ^see where im going? is it possible? with infinitely more power of cource?

Uu cool

You must be wrong, I specifically asked them if it was just spinning magnets and they told me no! ME: "So you can guarantee that anyone buying the 'whitebox', when they open it, are not going to find that each of the 4 'engines' consist of an electric motor and a set of rotating magnets then?" HENDO: "Again, this is a misunderstood oversimplification of the concept behind our hover technology. If it was simply magnets and motors, it could have easily been done before. It isn’t. And it hasn’t." Guess they didn't want people to know they were buying $100 of hardware for $800!

but they are not hovering over metal so how do they hover over wood?

Ha. So when I first saw the title "Tony Hawk rides a Hendo hoverboard" I thought it's a prank like the other one. But your video explains that during WWII they could build a flying UFO after all. Curious - if the discs are nested, would the structure still be able to hover? All UFO's from my childhood movies used to show spinning nested discs. I don't understand much of phisics...

so how thin of a layer of metal would be needed on a roadway to be able to hover over it? if it were 1 or 2 atoms thick it would be way cheaper to pave a roadway and maintain it if all vehicles traveling over it were hovering.... that'd be sweet. that is as long as you can figure out how to stop without landing on the road and destroying it.

Why you don't try to use the electromagnetic fields? It would be much better, I think, because you wouldn't need lose energy for mechanical spining. But it's only my opinion of couse.

Now I know how the magnet hover board work so maybe there are magnetic field hover board or sth

Does any aluminum work?

So, you don’t have to fill it with super cold liquids? Haha!

There are 2 problems. The noise and the fact that it is only operating on aluminum. The real challenge is to make one that hovers above concrete, stone or even more complex on an uneven surface like sand, ergo: everywhere.

the hendo hover board is a prototype,therefore not perfect,but it's somewhat functional.

0:07 Today we're gonna fuck about the hendo hoverboard?

the funny thing is when you power up it sounds like the hover boards

it s the same concept of the maglift in shanghai

Basically how UFO are getting around . But a little more advanced.

Instead of using real magnets wouldn't it be easy to use electromagnet and pass alternating current through them?

Awesome demonstration but that noise of the motor killed my ears

This is similair to how a asynchrone electromotor works

Aluminum isn't magnetic... how does this work.

What willl happen to all that heat generated by the eddy current? Massive heat sink? Hmm sounds inefficient to me. Unless somehow turn that back into generating electricity.

They could have just used the induction machine stator, without the need of using rotational parts, nor magnets...

It's true..

This technology isn't surprising. How many aluminum trails, roads or paths is anyone aware of? It would be cool to make a court or rink sized arena of aluminum and make some sort of new sport though!

I dont see how they use this to hover above the ground

It doesn't work for me tho
