Hover board
David Ashton   6/21/2014 4:29:16 AM
@Max....a practical and achievable DIY strategy might be to aim between the two.  Use the leaf blower (or two or even 4 of them) and use a controller to control them (and/or control surfaces or vents) such that you can command motion in any direction like the big one, or maybe have an additional leaf blower or a fan for propulsion like a swamp buggy.

Just make sure not to fill it with eels........ :-)

I think Max should rig up a tow line and let Mum pull him with her Toyota iQ :-)

Now, that would be a thrill ride -- I'll start practicing my screaming immediately (I think my usual scream when I'm riding shotgun with my mom will do nicely as a starting point :-)

Plywood and duct tape

I like the plywood and duct tape construction.  Very practical.  That way, when you (ahem) "land", you'll be able to use the pieces of broken plywood and tape to fashion temporary splints :-)

Skirts

For a practical hovercraft, (using a rather loose definition of "practical"), a flexible skirt is vital. Apart from increasing the ground clearance, and sealing the airflow, lifting panels can be used for control. Depending on the proportions, pressure, &c., control might be possible simply by titling the platform. Leaking air and Isaac Newton do the job.

Hover Board (performance & forward thrust)

I think perl_geek is closest: you need a skirt (like all hovercraft have). But also, I don't think it is cheating to have 4 tiny low-profile wheels spaced 90 degrees apart, to keep the leaning platform from nose-diving and biting into the pavement, thus spilling our Max in a most MAXimum way. By leaning, the leaking air will provide just a bit of thrust, at the expense of altitude on the leading edge (thus the need for the protecting wheel). Want more, just remove the governor (?) if it has one. If it doesn't, then shave the cylinder head to increase the compression; but watch out, it will get very hot, so you will need to adjust the fuel. Oh and by the way, the engine could spit its shaft, so have a metal plate between the engine and you. Just a thought or two.

Hi Max:
I did an article on an "alleged" hovercraft skateboard a few years back. I say alleged because after interviewing some aerospace guys I was skeptical that you could control the device under ground turbulence conditions. We sent a photographer to get a picture of the guy who built it hovering on it (he lived in England, go figure) and when the pictures came back I felt kind of like I worked for the Weekly World News as you could sort of see a faint shadow under the board like he might have been a few inches above the ground, but then again it might have been a smudge on the sidewalk!

Would EETimes be prepared to invest in a high-powered gas leaf blower for me to further my investigations, do you think? I can imaging myself sailing around EELife! 2015 waving a cheery hello (or perhaps a cheery scream) as I shoot by...

Please, take loads of pictures of videos of the "inaugural flight" if you finally do that: this would be worthy enough. LOL

By the way, maybe Adam Carson could help you. After all, he is our official "Aeroengineer" ;-)

@Max....the guy in your video could only hover and be "pushed around" by his friends (the term "Friends" is used somewhat loosely in this context).   But maybe it's like learning to ride a bicycle, or surfing, and just takes practice.

But please take lots of videos for our edification (and amusement :-)

Sorry for the pun...  Well, no I'm not.


I'm (only) guessing, but I think you could steer the board to some extent and cause it to move by managing where you put your center of gravity.

 

That is, if you lean forward (for instance), the skirt to the rear will lift a bit, allowing air to escape in that direction - thus pushing you forward...

 

Or, as others have intoned, add another leaf blower.

 

At my college, there was a regular hovercar racing thing they did with hovercars built there on campus.  They generally used an aft-pointng fan with rudders (much like an air boat).  There was a "scoop" at the lower portion of the fan which channelled air under the body to fill the skirts.  Thus, a single motor/fan ran the whole kit.

Hmmm -- this sort of gives me an idea. Suppose you had a reallyt powerful leaf-blower, so lots of "umph".

Now suppose you had two small flaps mounted on the back of the board -- spring-loaded to keep them closed -- each with a string that you could use to pull them open -- and if you did pull them open they acted like small jets pushing you forward...

When I spotted this post I immediately flashed back to this amazing video that was posted last week:  http://www.electronicproducts.com/Videos/The_surfboard_Hoverboard_you_ve_only_dreamed_about_is_real.aspx#.U67xLfldVtM

Max- I can just see you riding one of these!!

Actually, I'm having a bit of trouble believing that it's possible for anyone to ride one of these.  Think it's real?

Also- here's an interesting clip of a jet-powered hoverboard:

I like seeing the evolution of their concept as the video progresses.

I think it is -- I remember seeing the first version -- this new one seems much more "sprightly" -- I bet it's not anywhere as easy as it looks though :-)
