another one-wheeled skateboard

[ConflictedMike]

I don't understand why we can't think this is lame. If its done as a hobby then cool but if anyone is thinking about making money then shouldn't everyones opinion matter. Lots of people have gone broke by only listening to yes people.

[colemanhammer]

@ConflictedMike = moron

[ConflictedMike]

@colemanhammer Nice comeback. How about an update 3 years on. Are you able to have a conversation about it or are you only able to insult people. I'm genuinely interested in your motivation behind this.

[colemanhammer]

@ConflictedMike Why did I do it? To see if I could. Why did I document it? I suppose partly to prove that I did it (ego) but mostly so that others might be able to take something from what I did and build upon it (as I did from those who came before me). If you want to have a conversation about it, all you have to do is start one.

[bunjit1]

Hey Inventive types, don't worry about the bullshit comments from the herd. Just remember the old "sticks and stones" saying and you'll be right.

People who get on here and rag others are always people who couldn't invent something in a million years or fight their way out of a wet paper bag. They just get comfort in their low self esteem insecure lives by attempting to belittle others. You can actually have a good laugh as the most vehement are always the smallest guys in every respect.

[gpmerlijn]

nollie heel b/s lip ?

[RYDERkN]

Hook that up to a V8 engine

[pWndified]

How are you gonna get up hills Mr. Uni-Board?

[NowWhatVideosCo]

Cool! Now do a 360 flip.

[The303youngblood]

Wow, that thing is so awesome :] i wish i had free time (and knowledge moreso) to make something like that..i bet you must've put quite some time in on that thing. Can't wait to see the day those things flood the market haha..i'm so getting one :) awesome video, great job on the work and time it must've taken, bet your proud.

[DerD4N13L]

How do u want o ollie?

or its just for rollin?

[TheGHOSTo2]

Can I like have that please or borrow I'll make a sick video of me doing tricks. 

[newgrounder2]

CALL IT A UNIBOARD :D since it has one wheel

[silentrage87]

i want to go down a hill on one!

good job man pretty cool

[PeronMiles]

pretty cool

[kriztuhfuh82]

that's pretty smooth!

[WTFKoduBear]

Dude, you need to sell that thing!!

[fuzzybunny1337]

That's pretty cool

[echo680]

cool machine! boffins rock. nice one

[hobbenaro]

never had to put his foot down to push only effort he has to put in is balance and standing, very nice

[CamaroRS1011]

all these 15 yr old punk skateboarders are givin u a rough time about it.lol I think its cool. Will get u rich a hell if u can get it more stable and to go faster.

[serdnaotikol]

have you made it yourself? ... It´s great !

[scolopede]

And here I've been getting around using my own legs! Ha, that's pretty weird!, I think it will "go" somewhere.

[BioLeEK]

WTF dont want to be mean or anything but it was slow and miserable but on the otherhand you must have spent ages making it?!?

[ARVash]

Kid was adorable and seems like the board works great! Nice job :D.

[saartje02]

lmao

[Donniemona]

just go stand by the wall

[mrDegan1]

Theres no joy to riding ittttt

wheres the original skateboard least you dont look like a zombie riding it eh

[sskatethe918]

Once again, another cheap knock off of skateboarding. And how can you call that a skateboard? There isn't a board.

[itsmoretoit]

no he should call it gayboard

[390MUDDIN]

Nice man, keep up the good work!

[I69Longtime]

do a tre flip lol nah but thts cool

[rokerchix]

THATS GOOOOD!

[Hell6hound]

very nice indeed this is the kind of stuff that makes you wonder how people are gona get around in 5 years. get a good power source such as lithineum and have it go maybe a steady 10 to 15 mph and youd be good.

[UWANNAWHATNOW]

yeah you should call it a monoboard

[javivideox]

excellent ment´s brillant

[cheddahmac]

sounds like a milf lol

[drummercikaiii]

kick flip ...

[Slambodia]

that is bad ass

[bv420247]

less time making one-wheeled skateboard and more time making kid less whiney. for the good of mankind, please.

[yankee5456]

no realy a skateboard ... its kinda shit ? it dosn't even have a board so you cant realy call it one-wheeled skateboard! if i was you i would get a life !

[stephenpallotta]

DID you make that if you did u better patten it.

[KSFALLGUY]

i,ll say its cool when i see someone shread it in a pool!

[0GrandTheft0]

now do a kickflip

[omanisquirrel]

AWSOME! you should make a company coz ppl would buy them (including me) nice enginering and good idea, very good vid!

[kiter147]

thats awsome that must have taken some time to make

only if it were faster :)

[jusgast]

This is freaking cool! xD

[fuckaverageusers]

Well.

My guess is he has an accelerometer, a microcontroller and a big motor.

Microcontroller sends power to the engine that drives the wheel, depending on the data received from the accelorometer which detects the level of the board!

[cruisercrusher]

wow that is cool!

[devilmastah]

hey i was thinking about building one for myself, can you tell me the range this thing has ?

[gregrach1]

Good work

[pimpinproductions612]

what exactly is the point of it?

[gallalalla]

how does that go?

[SH4D0WS74LK]

k that is awesome

[edhyd123]

its easier then it looks

[LuViNsP]

VERY NICE!! more like a monoboard, skate is four?

[theshorterstory]

my feet are hot! D:

[steamboatannee]

you could make some money selling those to rich kids

[mikepbullen]

Thats awesome. And if i was that kids mum i'd say "okay sweetie, well if you aren't clever enough to put shoes on you deserve your burned feet" :o) Wicked toy though dude!

[omgwtfbbqgtfo]

don't tell him to grow up man... that's pretty freakin cool. i bet he spent a lot of time engineering this thing. not many people (including you i'm guessing) have the brains to do this sort of thing.

[bactery4000]

i agree but whats the point of it?

[shvabo2000]

grow up dude

[birddoggarton]

Not even gonna comment on you.

Everything hasn't been invented yet.

Guys like this, and me I might add, make the world go around.

Awesome job.

[SkaetrPunk777]

GROW UP?! so he can throw away what he does?! and become miserable and bored like u! u pathetic loser

[super6plx]

ok that's weird. maybe it's just youtube, but who the hell are you talking to? lol

as far as I can see (I went through a few pages of the comments) I can't see one person who told him to grow up

how come every third video I go to has someone who seems like they're talking to nobody?

[ultimatefrisbee92]

Are you going to say that about the Segway too?

[shadyumpa]

i would cover the top of the wheel so that if a shoe lase or long jeans get stuck i dont fall face first on the ground but it pretty cool.

[linkfanatic13579]

how is it moving?

[MarkCoupe08]

Magic

[PMJ0123]

ya but it is lame.

[benitofinito]

I'm going to make a simpler one

[tjrieves]

ok, go ahead

[1giffin]

wow thats cool

[positivman]

did you make it

[123pspower]

pretty cool... you made it yourself? :-o

[joejon17]

Thats pretty cool.

[jdesean23]

i dont get why its called a skateboard when it only has 1 wheel and i know it says that but all skateboards should have 4 wheels

[colemanhammer]

and what would you call it instead???

[d256138f]

@colemanhammer Uniwheelmajiger?

[brianfranch]

you're right... Skate comes from the greek word Skeight (Sk = Half) meanning 4 wheels

[Dmajorproductions]

@jdesean23 i wasnt aware there was a definition of skateboard. a board that skates haha

[kankuro6666]

@jdesean23 you = dumb

[orozco124]

lame

[colemanhammer]

really???

I don't get comments like this. at least once a month, someone has the need to spend the effort to submit a "lame" or "dumb" or some other monosyllabic critique. Is this what we've come to as a society? A bunch of armchair quaterbacks who feel their voice is important enough to be heard but are then too lazy or incapable of offering up more than a single word?

[eatmydirt85]

good reply to that one I think your Idea is great.

[mrabdallahaldashti]

@colemanhammer atta boy. As an educated teenager ( im 16) i can only imagine how much it must suck to have people rip on you, when they could do nothing close to you. this is an engineering marvel, and even though it might not be the most practical thing to get around on in my opinion, it's a cool thing ! :)

[CoolDudeMuscle]

@colemanhammer That's just his opinion. Don't try to act like your better than him or something.

Interesting contraption you got there though!

[TTamRR]

KICKFLIP!!

[mkasabor]

kid in background is

lol

[aekae]

Maybe if you put a dynamo against the rimside and wire it properly, you could charge the batteries while you're rolling along at the same time? Maybe it could make your batteries last longer? Gotta have a strong magnet to power that dynamo coil though, or the output wont amount to much. And gotta have lotsa coils too. I wonder why nobody ever thought of putting dynamos in hybrid cars?

[llowrida]

we have tesla cars

[vamp999]

its from the future! 10/16/2007! awesome!!

[frogeye3000]

great job!

[Lions5303]

lol that looks cool

[istupidduh911]

now thay have to make one that u can do tricks on

[xTorrent]

Nah, this thing would be more for transportation than sport.

[burtonxboarder]

doesn't look much fun at all...

[electricunicycle]

Nice mechanical work! You may want to put a fender on it so your foot doesn't tractor feed between the wheel and frame. From experience with my electric unicycle, I can tell you that your stability issues would greatly improve if you went to a higher wattage motor (min 500W, 750W better). Higer voltages combat back-EMF that reduces torque at higher speeds. Consider 36V, the OSMC will do it. I hope to have my 48V 750W leviskate running soon with video to follow. Congrats!

[colemanhammer]

Thanks for the info. Since this video I went back and found a pid tuning tutorial on the web and went through their process. Ten minutes of that, along with some code modification has made a HUGE improvement. I'm getting some oscillation (overshoot) that's really only noticable at a standstill. I guess I'll have to do some more tuning.

What about battery life at the higher power? My finished weight at this point will be somewhere around 36 pounds. More batteries = more weight...

[electricunicycle]

Because the motor is basically a switching power supply, you will actually see longer run times per charge with higher voltage under the same load conditions (the pwm will run at a lower rate, providing more headroom)

Yes, It weighs more, it depends on your design goals. My goal is for a board that can go up steep driveways (mechanical clearance required!) Also ride on grass and yank my 240lb body around while balancing and go 10+ miles/hour for an hour.

[nahoruk]

How far can it go until you have to change the battery?

[colemanhammer]

don't really know, I'd guess it'll run for a half hour or so.

[bensmither]

That's absolutely brilliant!

[colemanhammer]

Thanks! And thanks again for documenting your work... it made the R&D(Ripoff and Duplicate) process soooo much easier!!!

But seriously, it's been a lot of fun figuring it all out.
