Better PC fan hovercraft

[amaliorad]

thats killer:)

[emomotorgeek]

Should've used some Delta's

[bratonabike]

now make it wireless.

[7260a]

WTF?!?! SHIT NOISE DUDE

[EdwardLaiPY]

u can make a GENX small1

[dontenvy]

haha this looks fun.. very idle but a cool home project lol

[Engageothon]

does anyone know whats the best quite PSU out there?

[XandalorZ]

Install a rotatable fan on the back and add a source for control. Then we shall have hovercraft races. >:D

[ThankGodForCod]

When that thing hits 88 mph, were gonna see some serious shit.

[TheFatal05]

@ThankGodForCod nice back to the future quote ;d

[DigiDavidex]

22Volt?

[cocobirdcoco]

Make it radio controlled and make the rear be able to switch directions, but drive it on a lake

[flexyco]

If you change the polarity, can u use it as a vacuum cleaner?

[AmazingDX]

@flexyco those fans don't allow inverse polarity.

[MrTejeshw]

better use some good brushless motor

[zogworth]

@MrTejeshw

pc fans are brushless.

Also, they are dirt cheap/free, decent motors really arent.

[elmasteryu]

nice!

[Born222kill]

thats no hover. thats a plastic bag !

[bobbilcon]

@Born222kill OH NO! You have seen through my vail of lies!

[MechanicalGeneration]

@bobbilcon I AM UNDONE!

[Born222kill]

@bobbilcon I dare you to do it in water and we'll see if it hovers.

[Fowtowsjop]

@Born222kill Do you even know how a hovercraft works??? it was clearly hovering...

[demonbreed131]

im guessing those are delta fans coz of how loud lol

[bobbilcon]

@demonbreed131 They are actually Vantec tornado fans. Don't know if you can still buy them but they were quite loud. They apparently peek at around 70db, that is if you run them at 12v like in a pc... we did 24 volts for more power out of them.

[MattewJohansen]

its a plastic bag under it -.-

[bobbilcon]

@MattewJohansen Its a thick clear vinyl but worked out great.

[TheRealTKillah]

@MattewJohansen thats how hovercrafts work...

[fss1704]

is most easy to make one hovercraft when u not use batteries.This guy is overvolting these fans,look the variable font on background.It's are running at minimum of eighteen volts,with the two coolers at parallel.It's a joke.

[bobbilcon]

@fss1704 It was actually 24v off of a variable power supply. Later that was attached to a plc to control the entire unit.

[derdernixcheckt]

really good!!!!!!!

[bobbilcon]

@derdernixcheckt Thankyou

[Pyromaceno1]

ha ha funny but cleaver too XD

[BOPReviews]

I remember having a PC fan like this in a very old computer.

When it was on full... Which it was all the time you could hear it from outside the house!

[bobbilcon]

@BOPReviews I would never put one on a pc personally. Its to much like a jetliner beside you.

[patrikk777]

wut its flying :D

[1CARROLLER1]

take off the grills to make it lighter?

[bobbilcon]

@1CARROLLER1 There was a complete idiot in that class. He seemed to enjoy sticking his finger into things, so we decided to keep them on.

[TheNotoriousJesus]

@bobbilcon

roooofffl! best comment ever haha xD rofl...made my day ha xD

[turtlepturtle]

@bobbilcon what type of fan did you use?

[LivingDeadJkr]

@turtlepturtle It's a vantec tornado 80mm. They give a awesome amount of cfm but were some noisy bastards.

[LivingDeadJkr]

@turtlepturtle It's a vantec tornado 80mm. They give a awesome amount of cfm but were some noisy bastards.

[LivingDeadJkr]

@turtlepturtle A vantec tornado fan

[Vocoder07]

hovering that thing over water too???

[bobbilcon]

@Vocoder07 Would of tried if I had more time.

[theron324]

try hooking it up to 12v or 9 v batteries

[bobbilcon]

@theron324 Had it hooked up to a variable power supply so I could control it with a plc.

[20ID]

I'm so doing this with my Tornados.

[thelightguy1]

Haha, those delta fans!!

[mefirez66]

put two on the back for steering

[bobbilcon]

@mefirez66 If you check some of my other videos I have rudders on it.

[ObtrusiveDave]

sick

[alphaguitar2]

floating computers ftw

[theultimatedestroy80]

@alphaguitar2 HAHAHAHAHAHAHAHAHAHAHAHAHAHAHA­HA LOL!!!!!!!!! :DDDD try that with your computer and see how it turns out..... just make sure you have another computer..... the waranty won't save you!!!! :P

[Samo762]

my hovercraft is full of eels! :D nice job

[lewisu2088]

That is awesome! would be awesome to see a case lifted by a bunch of fans :p

[bobbilcon]

@lewisu2088 That would be crazy, Try emailing vantec and see if they like the idea of doing that as a promotion. Could make a awesome video.

[TheUsmanelahi]

not impressive....!!

[The1337muffinman]

lmao

[plavins1]

you should take of those metal covers, it will not be as heavy

[SKMatoBB]

how many rmp has these fans?

[bobbilcon]

4800rpm with 119CFM

[SKMatoBB]

woooooooow

[jukka1996]

@bobbilcon that doesnt matter .. the important thing is how much m³ he can blow through in an hour

[TheGeek1028]

...put 2 on the side for steering o.o

[theonethatgoofs]

go g force lol.

[999grassy]

take the grills off (its added weight)

[bobbilcon]

It kept a low brain cell counted individual from hurting there hand.

[ObtrusiveDave]

@bobbilcon lol

[PJdacoolDJ]

LOL mine looked better than dat but dat works :)

[pinodeltoro]

LAME!!!!!

[JonDeth]

congratulations!

you built a useless piece of crap

[bobbilcon]

Yep but it was fun. And for a school project. Check the rest of the videos for the rebuilt verson. Its pink.

[1CARROLLER1]

well said

[cokernator]

dang, those tornado fans are loud. i actually put one of those on my pc, and I immediately took it off because i couldn't think hear myself thing.

[Millsie18]

Yeah, Thing is pretty hard.

Loud sounds always interrupt me.

[saitek658]

dude ho much volt do you yuse

[bobbilcon]

as shinny as they are they dont quite have the force you want. Given for the size they are really awesome fans for a pc. Quite but i just wish i could attach a switch to the leds to turn them off.

[mewaysagent]

lmao at all the ppl tht did not relize the strings and the noise was about as loud as a vacume cleaner.

[bobbilcon]

yah when i had them going at school the teacher in the next room actaully came in to tell the janator to stop vacuming.

[thehidd3ntruth]

vantec is false advertising saying thiers are stronger and faster cfm and rpm than deltas

[bobbilcon]

I actually had to check this out. Its not false advertisement at all. The deltas do make stronger fans but one of the problems is the wattage is all over the place and not at 1.2

[rb1003]

wtff

[runescapemischo12331]

too loud

[bobbilcon]

thats a the wonders of the tornado.

[rndydy]

I used Delta 120mm fans on mine, work good for that.

[bobbilcon]

I bet. How was the sizing with them? For my size 82mm fans were pretty big on it.

[rndydy]

Im not sure what you mean on sizing? Sorry im only about a year into computers.

[bobbilcon]

like on the hovercraft. With the size of my hovercrafts body they 82mm fans were just big enough.

[rage02k]

I have no clue how your PC fans managed to generate the lift. But my PC fans cannot generate enough amount of lift. Have you tweaked them or something?

[bobbilcon]

They are called Vantec Tornado fans. The strongest fans you can buy. They push 30 cmf of air and run 60-80 db. Powerful little things. They are strong enough to push them selves across a table.

[hypnotekk]

30 cmf?

[bobbilcon]

that is how its spelt

[hypnotekk]

im not asking how it is SPELLED, i am asking what units they are.

[bobbilcon]

ok ok, They are called Vantec Tornado fans. They are the 92mm ones

[hypnotekk]

do you know what a UNIT of measurement is?

m=metre, cm=centimetre,N=Newton etc etc.

what UNIT does cmf represent?

i would have thought a volume flow rate equation would be used, or mass flow rate, but i can't guess what a cmf represents.

so if anyone can read and understands what i am asking, then i would love to know: what does CMF represent?

[IHunger4Battle1]

It's actually CFM. Cubic feet per minute (in this case, CFM of air blown by the fan).

[hypnotekk]

so it IS a volumetric flow rate.

still haven't joined the rest of the world in using SI units then?

thats why that mars rover, beagle 2 crashed you know, cos some yank useds feet instead of metres.

SI unit of vol flow rate=m^3/s

[bobbilcon]

I try my best to use SI units but they refuse to stop teaching impreial in college so im forced to use it. Can you really just blame one side for it? It was orignally being built by the "yanks" then parts were out sourced to brits. Apperentally no one ever said they were doing either,

[theultimatedestroy80]

@bobbilcon well then you have to see my 6,5'' fan!!! i powered it wile it was on my desk so i can test it.....and it went from the one side of the desk to the other side.... i was like WTF???...it's a bad idea to put your finger in it because it will hurt!!!!

[aSASa45454]

actually delta has the strongest fans but those look powerful as well ;)

[kevjones93]

now what you need is two smaller fans on the sides so you can steer

[bobbilcon]

If you look at my videos I have a updated version of this with rudders on the back to steer.

[dentinhodabaixada]

ronaldo

[VKGchaos]

wooooooo

[Ryuuken24]

I got two of these. Jesus crist, they make such noise, its impossible without the fan control. But they can chill like hell. Cpu Athlon X2 6000+, Thermalright TRUE Copper idle 20 C, full load test, Crysis 40 C.

[masterwolf1212]

I am planning to do this, but I was just wondering, what was the skirt at the bottom made out of? (The inflatable thing at the bottom)

This is VERY nice!

[bobbilcon]

The skirts made of thick clear vinal. But any think clothlike material will work

[masterwolf1212]

Thanks so much! I might be making one over the weekend with a 200mm computer fan for the skirt, and a 120 for the back. I will definitely make a vid and send it to you if I make one. I am gonna try and get a very loose wire (bends easily) so when I use it, the hovercraft isnt getting pushed by the wire, and get a very long wire. I also will try and make it so I can go on the water. My plan is to put the fans in the enclosure with a nice sized vent built to give in air, but protect the fans. :D

[blaky8602]

it wont turn right

[bobbilcon]

well it kinda failed at doing more then 1 turn. It could but i would need the area to turn and since its attached to several cables and air hoses it just failed.

[tiagom135]

can get powerfull ones with - noise

[bobbilcon]

i dont understand. Are you saying to get more powerful fans or i have no clue... The fans on there are the most powerful fans you can buy for a pc (92mm)

[tiagom135]

forget u said that they are the moast powerfull

[ciusix1993]

can it go on water?

[bobbilcon]

never tried but it was able to hold its weight well enough on land i figure if i could git its air glowing right it would be fine.

[electrovoxus]

Thanks bobbilcon

[ciusix1993]

5 stars dude, 5 stars...

[bobbilcon]

thank you. its good to know youtube isn't just filled with people slamming every video

[electrovoxus]

Cool! Can you please tell me how you made that?

[bobbilcon]

Make a base. Something that is light and durable. Make sure it will hold all your fans used for list and movement. Batteries if you want to use those too. Find rubber or thick vinal for the skirt. Lay the body on in the middle of the skirt. Cut the skirt so there is 1-3in of material extra on each side. Attach the skirt to the body then. Make sure you have cut a LARGE hole in the bottom of the skirt to allow air to move out of it. This will create the needed pocket of air to float on. enjoy

[Tomasch]

But your stupid machine can't even transport anything. So it's useless and it sucks. Get over it.

[bobbilcon]

It may not be able to transport anything of any real size but its a small size. I don't need to build one that is full size because it was used as a tool for learning. Have you ever had a puzzle. When you completed it what did it give you? Nothing of physical value but the learning experience, That`s what this was for. Just because it dosent transport anything dose not make it worthless.

[Tomasch]

What you build doesn't make sense and nobody needs it. So get a life.

[bobbilcon]

Hovercrafts make plenty of sense. If you need the ability to go over water but there is some small land obstacles in the way are you gonna try to navigate around in a boat or just hop over it in a hover craft. They are still used in this world. It wasn't built for nothing it was built for a project and to test of the posses of engineering. We started off with drawings then went digital. We then started off with models to test to see if it all works and then moved through making these.

[Tomasch]

that's gay, get a life

[bobbilcon]

How can this possibly be "gay"? I build robots using plcs and pneumatic systems and you troll youtube telling people that what they do is gay. there is something very wrong with you.

[hussainmushahid]

2,9 volt batteries will make 18 volts?? Or it will just make its life expectancy longer??

Also at how many volts are you running it??

Are 22volts enough??

[bobbilcon]

its running at 12 volts and yes batteries work but i was using a plc for a project to control it.

[hussainmushahid]

You are using tape to block any release of air from the top of the hovercraft??

[bobbilcon]

tape, staples to hold the skirt and a lil hot glue

[aznturtle1]

all you need is steering and a hamster pilot

[bobbilcon]

agreed about the hamster pilot but if you look at the other videos i have there is a steering device.

[hussainmushahid]

I want to make an hovercraft of my own,have already made alot simple ones but now its time for an advanced one.

I just want to know what is the skirt used for?? Is it covering the whole bottom of the hovercraft?? Should It have no air escaping??

[bobbilcon]

the skirt is used to focus the air under the body of the craft, creating a cushion of air. It dosent cover the entire bottom either. It rolls over for about 1-1/2 inch around the bottom and then the rest is left open. My best suggestion for you would make one that covers the entire thing then slowly cut out a rectangle bigger and bigger till its working well.

[hussainmushahid]

Thanks

[hussainmushahid]

One more question which material is best to make the skirt?? Can I use rubber from those b.p apperatus which I have lying around.

[bobbilcon]

your best bet is something that is flexible and durable. Its its rubber it should be fine it just needs to have a large surface area so it can make the skirt. I used a vinal map bag for mine. Worked out great.

[monQlol69]

does it need holes in the bottom????

[bobbilcon]

you need a way to force air under the body. Easiest way is by having a hole cut for the fan.

[yellowblutac]

A very creative use of pc fans, nice one. To add to some of the comments below, I believe you would be able to make it battery powered if you removed alot of the casing from the fans and replaced it with something like styrofoame. Then if you used rechargable batteris you'd be in business! :)

[bobbilcon]

if you look at my other videos the base is redone with a Styrofoam base. I still didn't use batteries on it because part of the project was to control it with a plc. So it still has to be tethered to it with the wire. I would love to have done it with batteries too. I even had several battery packs from cell phones that would of worked awesome for it.

[ipn92]

OMG ! very creative , nice one

[bobbilcon]

Thank you very much. :D

[DasAntiNaziBroetchen]

lol

[cheetawolf]

now just get it to run on a battery, and that would be SAH-WEET!! :P

[bobbilcon]

Its actually impossable to make it work with what i was using. I would need to tripple the size to support a batter giving out 12v 3A long enugh to make it worth my while. Then i would need to add more fans to keep it going. Not to mention that i have compressed air allowing me to use the rudders on the back. But if i change up its style then yes i could. Pop a 3-5 cellphone batteries and i would be in bussness

[VeryTucker]

or you could get fans with the same velocity with less amps.

[bobbilcon]

i dont even know if thats possable. These fans are the strongest fans I could find. And running of 12 volts for 80cfa is impressive

[VeryTucker]

yes. if you did my idea you would problably need 2 more fans.

[ybnrvdh]

hey if u buy rilly cheap remote control car toy on ebay u can open it en try to make it good so it can turn and shit

i am form holland so i cant make good centences :D

[Dukiiiii]

I'm from holland too, and your English doesn't necessaraly have to be that crappy.

[ybnrvdh]

lol some can speak it better than others ..

so why are u being all smart guy with me?

[Dukiiiii]

It's not really aimed at you, it's that you dont have to be so bad at english when being dutch, because the way you say it, it's like every dutchmen sucks at english, that's all.

[tofu4tortoise]

that...was...AWESOME too bad i cnt make one=(

5/5

[bobbilcon]

its easy. and if you spend a few more $ you can make the rudders actually work.

[traxxas4me]

what did you use for the bag on the bottom?

[bobbilcon]

I used a waterproof map bag.

[masterchief3k]

vantec tornadoes?

[bobbilcon]

fans.

[rkb12222]

is that like the computer fan from hell, its loud did you make it better some how?

[bobbilcon]

Yah. Its ment to run at 15v but i have it turned down to 12.5v. When i turned the power up to 35v (max the power supply would give) the fan would push 70db. Normally the fan runs at 55db so its at 45-50db. You should know even turned down the fan is strong enough to move its self. At 35v its strong enough to rip its self off a table when its duct taped down. Very impressive fans.

[daanie250]

jij bent nerd weetje

[zwitdana]

wow

:O!!

[sbaglieri23]

get a rc car steering axle and connect some metal rudders and have the controls from the rc car steering on to ur remote u use and there u go a steering shaft

[bobbilcon]

we tried ripping apart the steering device from a rc car. It turned out it was just 2 magnets that magnetized to turn it. And when we tried to re assemble it the shell broke so we gave up. But if you look at the latter videos its remade with a pnumatic cylinder to move it.

[Maticus2009]

With Xmods from radio shack you can upgrade the cars for gear turning instead of magnetic.

[bobbilcon]

I never knew that. unfortunately we no longer have radio shacks. I am working on a miniature house that is controlled by computers.

[masterchief1212]

That's pretty fucking cool.

Nice idea, work on the steering next :P

[Fr0z3nFr0g]

wow, shake enough?

[bobbilcon]

nope...

[WeretFilms]

Not really...

[Desolator1]

hmmm I could use one of those, though they are loud

[CamsYT]

Made one with Thermaltake 125mm, they have enough unf for what is needed but the power requirements make it difficult to keep going + weight of the batteries. (4 9v)

[bobbilcon]

if you have a few pictures of it or a video i would be more then happy to take a look and see where you might be able to get some more umf out of it

[mashphat]

you should try getting more up rather than forward, its pretty pointless having forward without steering so its really just adding pointless extra weight.

[bobbilcon]

if you look at the rest of the videos i have i added stering and made it actually float

[rootbrian]

Awesome.

[slaterking1000]

THE FUTURE OF TRANSPORT IS HERE

[Bla918]

They look like PSU's.

[zx169]

Is there a specific weight to power ratio in order for a hover craft to work? And does the engine that blows the air underneath has to be in a certain position?

[bobbilcon]

there probably is a ratio. I really don't know what it is. General rule i learned is build lite and get some strong fans. If you can get a turbine kind of engine to push more air under the craft. Something like a hand dryer from bathrooms. Or get a Aerocool Turbine 120mm pc fan, it should do the job. the engine must blow the air into a even position at the middle of the hole in the skirt. This will create a nice cushing of air for it to float on.

[zx169]

Aight, thanks for the info

[bobbilcon]

no problem
