On your next instructible please use the "macro" setting on your camera, these pics are really blurry.

PC fans have electronics in them so reversing polarity would be like reversing polarity on LEDs- It won't work. (some times it might turn in the same way no matter what the polarity. this is a protection feature on some fans)

Umm, it doesn't matter which direction the fan is facing because you can just reverse the polarity of the wires.

now days no computer fans reverse polarity

Mar 16, 2010. 9:27 PMMudbud says:

Yeah it does. some fans dont reverse polarity. :)

Feb 2, 2010. 1:53 PMdildo224 says:

Uhm when i reverse it the fan dont work?!?!?!

Nov 24, 2010. 12:15 AMDrasa says:

If you reverse polarity your fan will also go reverse.

no it wont fool

Jan 2, 2011. 8:27 AMDrasa says:

I meant fan, not motor. Sorry.

Jan 2, 2011. 8:26 AMDrasa says:

Hmm, weird because all of my motors go reverse then. Also no need to call me a fool and break the "be nice" policy, I may be wrong.

the fan blades are shaped to spin a certain way

Jan 3, 2010. 4:56 AMgoobyalus says:

Not with a brushless motor.

Jan 13, 2012. 4:15 PMxboxmodmizer says:

but its as clear as water it wont word just turn the whole fan over the computer fans specially brush less only go one way but if you flip it over you'll get the effect you all are looking for

Can this hovercraft lift a little weight? I was thinking you could add the guts of one of those $10 r/c cars on top. You could have the drive motor power another fan and the steering motor move a little cardboard rudder right behind the drive fan. R/C hovercraft!

awesome!!keep making cool stuff!

"mini hovercraft" meh. Fabulous 27 volt battery idea? Priceless! heck, bypass the battery clip costs, and use the clip from one of the soon to be dead 9-volt batteries! Most can be cut with a pair of scissors. Others can simply be scored and snapped.

I wouldn't expect that 12v fan to last long running on 27 volts. Short tests shouldn't burn it out too quickly though.

May 24, 2007. 6:06 PMlearningmaster (author) says:

mine wasint 12v it was a power supply fan

May 24, 2007. 8:12 PM

LasVegas says:

Fans in computer power supplies are 12V fans. Look at the label on the fan.

Dec 20, 2009. 12:39 PMsci4me says:

i used a 12v fan with like 50v and it just barely lifted off da ground, but i didnt have a cup or anything.

May 22, 2007. 11:05 PMBlue_Dream says:

Dude. Tell me you like 13 or something? Or just really board. lol Just kidding' I was wondering when someone would post a hover craft. Did you thing about doing something to reduce the friction between you craft and the surface it glids along? Like maybe using the lid from a pickle jar at the bottom so it would slide easer?

May 24, 2007. 6:05 PMlearningmaster (author) says:

i was rely board and made somthing and it worked and i am 13

Dec 17, 2007. 9:45 AMfordman15243 says:

hey I'm 13 and when I'm bored I can make better stuff than this! (oops no offence I meant to reply to Blue_dream SORRY!!)

May 8, 2009. 7:05 PMharley_rly says:

hey im 14 and do stuff like this when im board(and also when i was 9-13)

Jun 17, 2009. 7:19 AMxSyntaxErrorx says:

LOL, I'm 15 and I does this kind of stuff too when I'm bored...

Jun 22, 2009. 4:04 PMraimen says:

hey I'm sixteen and I make real hovercrafts lmao of course, a leaf blower has a bit more kick than a 12v computer fan xD

May 24, 2007. 6:07 PMBlue_Dream says:

Jun 21, 2009. 6:49 PMThe Red Button says:

Actually, there are already several hover crafts (none like this though) posted on this site.

To take up close photos, press a button on your digital camera that looks like a little flower. Hold a your picture button down half way to focus. Then press it all the way to take the photo. You still need to be about 6-10 inches from the object. if you want the photo object closer, try using your zoom. It won't affect the focus. Good luck and thanks for posting these instructions.
