Simple PC Fan Hovercraft

[SianaGearz]

I'm sorry, but... is it full of eels?

[Wast3m]

well the next step is to make a rectangular frame out of modeling foam and add 2fans. 1 strong and light rc car motor and a high efficiency motor for the propulsion.

[ducksatschool]

i used a 12 volt transformer

it works better and doesn't run out

[dingo27mobile]

Use small duracell 12V battery, or two. Its super lightweight, but its quite expensive.

[0922997]

use 2 12 Volt batteries instead. They're lighter so you can put them to the hovercraft.

*imaganing a car battery* O_O

[elementskaterforlyf3]

imagining the tiny wires getting overloaded and starting a fire. >:D

[lolcat360]

@KirbyNicoDDR *imagining a car cooling fan*

[dale456654]

You can power a computer fan with batteries?

*Throws the 20 metre wire in the bin*

[ellimist45]

Well... I would not suggest it for inside a computer, because you'll be replacing the batteries every day.

[mystikdev]

@ellimist45 A PC power supply runs on 12 Volt DC your house runs of AC so basically the power supply takes your AC converts it to DC and then scales it down to 12 volt DC, batteries are also DC power, so 8 AA batteries(or as in the video 1 9v + 2 AA(1.5V each) = 12V DC

[folken692000]

@dale456654 What makes you think you couldn't? 12V is 12V...

[dale456654]

@folken692000 suppose I got mixed up between AC and DC power.

[GoldFishPro9999]

coo i took a fan off of a dead computer hooked it up to a 9 volt adapter connected wires. then i got a switch on the back of the computer and tied it to the 2 red wires(because i dont have a soldering gun) but its pretty cool and portable

[bryanobi]

and also, how'd u take the rubber off the wires so it only has the metal parts sticking out?

[ellimist45]

Wire stripper.

[224StuartWhite224]

get a knife and only cut the rubber layer and pull it off, or use cutters/wirestrippre

[Lazzlo000]

@bryanobi or a lighter, just burn the insulation off

[eivis13]

@bryanobi or plain tinkering with an exact-o-knife

[bryanobi]

im just wondering... how did u wire it on? cuz i have a school project due tmr, and i really need to make it fast. also.. can u turn it off when u want? or does it have to run until the battery dies out? explain plz and thanks !

[ellimist45]

I used electrical wires.

I didn't bother to put a switch on it, but you can. They sell them at RadioShack.

To turn it off, I just disconnected one end of one of the wires, which opens the circuit.

[bryanobi]

how did u connect the wires to the battery? im new to this (: i got 2 9v's and do u just wrap them around the + and the -?

[ellimist45]

You could do that, but they don't hold well... so after doing that, cover them with electrical tape.

Also, careful the polarity if your fan cannot reverse - you'll burn up the little motor.

[bryanobi]

so there's no way of stopping them without taking one wire off completely?... without a switch i mean... right? (: thanks a bunch so far.. but how am i gunna bring it tmr if they batteries are dead?

[ellimist45]

Just disconnect one end of one of the wires...

The charge in the batteries will not be used unless the circuit is completed.

[KUFULEE]

ya ul burn ur mama u think u know stuf

[chsxtian]

does it work at 8 AAAs? it might get unstable at high speed.

[ellimist45]

Sure, why not?

[cachia02]

are you pulling it around ? lol

[ellimist45]

lol, yes, to indicate that it is floating rather than dragging/sitting.

Are you lacking in perception?

[Speters13]

can i put a skirt on the hovercraft..and not the clothing....lol?? adn if you can then how?

[ellimist45]

Yes.

With scissors.

...

[Skater785]

cause i saw this other vid the same like that and it shows you wat you need and it said tape so im thinking reg tape

[ellimist45]

Well sure, but electrical tape is insulating, so it will prevent short circuits better... in case you have any stray wires.

Try both. And improve on the simplistic design.

[Skater785]

can you use regular strong tape?

[ellimist45]

Probably.

[Skater785]

i got every thing i just need to know how you connect the wires

[ellimist45]

Electrical tape.

I swear.

[Skater785]

sweet how did you connect the batteries to the cp fan wires?

[ellimist45]

Electrical tape.

[gassiej]

can u help me? i have a PC fan and 2 9V batteries on some white foam from a box, but it wont lift, how do i get more power?

[ellimist45]

The white foam is probably too heavy.

I assume the 18 volts is powering the fan, but how much energy is it supposed to take?

Is the white foam in a shape that is both radially symmetrical and has edges close to the ground? It could also be square.

[gassiej]

the foam is so light its floating like a leaf and its symmetrical, i cut out a hole as big as the fan, and i hold the batteries in my hands. Its a rather small fan, its DC 12V 0.14 A i think.

i have another fan with more A's

[ellimist45]

Well, in this video, I have a 9 volt and two AA batteries connected together to et 12 VDC, which is what the fan requires, so your 18 V might be too much.

Lots of questions:

Is the fan at the center of mass of the foam, so does not tip either way and drag?

Also, are there air leaks around the fan?

Does the foam, without the fan powered, lay flat on the floor?

[ronspeck]

If there was a way to propel air in the direction you want... you could make a remote control hover craft I wonder if it'd be possible.

[pacalooka]

sounds like a vibrator

[electricdixie34]

thats magic

[atatyrknumber1]

i got 7 fans from scrap yard :P going to make one :)

[jlmKids]

hey dude heres a good idea... see if u could get more of those fans and find a bigger and stronger base, find a spot for the batteryholder and test her out! i never tryed it but hey its worth it right?

[DxlilxD]

cool

[mastrsushi101]

Is that the one from radioshack? Im making a hovercraft using a 12v battary too.

[FUCKCHRISHANSEN]

what did you make your battery thing out of?

[ellimist45]

1 9-volt

2 AAs

Connected with electrical tape

[FUCKCHRISHANSEN]

thanks man!

[mastrsushi101]

whats electrical tape?

[blaneblane10]

lol tape that electricians use.

[Ornafulsamee1028]

I might soon, but it still needs some improvements before I film it

[Ornafulsamee1028]

I did the same thing, only with a pc BLOWER, which was attatched to a 20 vdc power supply

[ellimist45]

Awesome! You should video record it and put it on YouTube.

[xXazncupcakeXx]

lol, thanks, i meant using then batteries, like holding, it, lol, thanks anyway though, lol wow i sound so dumb to the prior comment, lol w/e i got an A so, lol thanks ^_^

[xXazncupcakeXx]

cool but will it hover without the remote thingy?

[balderdash707]

you mean the battery?

[ellimist45]

That is the battery(ies).

The fan requires 12 volts and cannot have any more or any less.
