meh.. if the ice comes from a fridge in the same apartment, then you will be adding heat in your home. Not a big amount, but still this doesn't make much sense

dwtech made it! (author)2015-07-07

This is a picture of one I made, basically like the instructions except the air goes in through the top and is pushed out through holes on the front at the same level as the ice. I aimed it towards my mouse and keyboard and even though the fan is fairly low powered, it already feels nice after 5 minutes. BTW, I made this in around 30 mins with: a salsa container, a cpu fan, an old apple charger cord (usb), and a drill for the holes. I also used some masking tape to hold on the fan b/c I was lazy.

i have designed a similar version inspired by it that uses an arduino chip ATMega8

and controls the fan speed according to the amount of external temp.

it also warns that ice is melting , etc...

it also has a lcd display and humidity centre and is fully automatic and also monitors the battery level and recharges automatically when plugged in the socket..

it runs on 9 v dc...

it is so auto-cool.............................

anshuldakshini (author)HarshV2015-06-09

Dear HarshV... could you please draft your device's tutorial... a step-by-step one.... as i was thinking on the same ground but could'nt succed yet... thanks friend

Sabbadeus (author)2014-07-12

sad to say that it did not work. it did blow cooler air, but so little that the heat you will produce while making this will be greater than the cooling you will get from all the ice your freezer can produce.... I really like the design and idea though. Maybe i didnt have all the right stuff for it.

techno guy (author)2012-07-12

dude, this is so cool, where i live right now is soooo hot; this works so nicely and cost me nothing to make; but the ice goes away so quickly, it doesn't melt, it disintegrates, but the byproduct is freezing cold water that i'm considering to drink, good job on this 'ible

anandal (author)2011-12-08

can anione of u, help me out in designing this setup on basis of technical datas like( container volume, fan power,ice qty., temp. difference etc... ) required for 1 person nd for 15 persons ?

DhanushkaYT (author)2011-08-26

i'd try using a thermoelectric cooler {peltier unit}

nacho.cheese (author)2010-06-03

nice, but maybe I will try that one with a bigger container..maybe it can refresh a bigger room....nice project

Try it with more fans, and a larger container, like a cooler.

If you're doing that, use Ice packs (Such as Nordic Ice) or frozen water/gatorade bottles.

And use some fans to draw air in.

suboxygen (author)2010-07-06

nevermind.. i used whatever worked haha. i made one! sadly, the fan is so weak.. i can feel it drawing cold air out, but its really weak. is there... an easy way to... say, use two USB outlets to combine 10 volts to power the fan more? I made mine out of this big Tin box that a bottle of southern comfort came in.. its really cool. looks nice and its really tall! I love the idea.

suboxygen (author)suboxygen2010-07-08

heres the pics of the version i made. Needs more juice in the fan area though. I used a plastic like CD case, it was bendy plastic to make holes in to hold the ice. It worked fine, drained without leaking. Cool instructable!

Ok, do as I did. I amped it up a little. I don't have pics now, but I will later.

Essentially, have one fan running air intake, and one to blow the air at you. Intake at the top, ice at the bottom, fan blowing air aimed at your face.

It's that simple, and all you have to do is rig it up to a single usb cord.

Bartboy (author)2008-06-29

its portable! you can use in car with an Ipod car charging usb thingy from apple!

extremegtafan (author)Bartboy2008-10-17

Or you could simply roll down the windows.

Bartboy (author)extremegtafan2008-10-17

no it does not help in saskachewan

MCzone (author)Bartboy2011-07-18

how many trees have you found so far?
i lived in edmonton for 6 months, not one tree

extremegtafan (author)Bartboy2008-10-17

Oh. I don't imagine this cooling a whole car, though.

MCzone (author)extremegtafan2011-07-18

2 or 3 mabey, also try running the fans (of the car) with no heat or a/c

Bartboy (author)extremegtafan2009-01-22


diegolay (author)Bartboy2009-01-22

Why not the real air conditioner that comes with the car ventilation system?

cuz its broke

tinkerC (author)diegolay2009-02-22

Because you can use this other places, like an airport, or in a car with a broken AC unit.

robotguy4 (author)2009-06-22

Note to readers:
Make sure that the holes are NOT at the bottom of the tin. If you do this, after the ice melts, the water will flow out of the holes.

Tapeplayer (author)robotguy42010-06-24

ya thanks for ur imput. Ive i almost did that then i was like oh ya.

MCzone (author)Tapeplayer2011-07-18

put a cup under the tin

MCzone (author)2011-07-18

I am going to make one from an altoids case and a cpu dan (usb powered)
thanks for the idea

robotguy4 (author)2009-06-22

Note to readers:
Do not OVERFILL your container with ice. If you do this, after the ice melts, the water will flow out through the holes you drilled.

Nice design, by the way.

MCzone (author)robotguy42011-07-17

try putting a drip catch under the container

gccradioscience (author)2011-06-22

I have not made one yet, but how do I find a container that fits a CD with holes in it. What size do I need? Also how much speed do I need for the fan to put out enough cold air and what size fan would you recommend. Thanks for showing me this project thanks, now I can probably build something better that will keep my netbook much cooler one day.

hdhiman (author)2011-05-14

i recommend adding some salt on the ice

hdhiman (author)2011-05-14

thanks i made mine for my car

psoria martinez (author)2011-04-19

Recomiendo usar un motor de mayor potenciay debajo de la lata de matal colocar algo para que no sobresalga el agua accidentalmente. Un trabajo estupendo! =)

crtn2 (author)2011-04-01

i'm not sure this will work. USB can't provide enough power.

Wally_Z (author)2011-02-01

You could, if you wanted, drill a hole at the bottom of it, and run surgical tubing to a bucket to catch the water runoff.

Gr3at_Whit3_North_Guy (author)2010-10-07

How do you splice the two fan wires to the USB cable. I am trying to make a simple homemade usb powered USB inter cooler

levigray (author)2010-09-19

I have not tried this yet, but like the design. Has anyone tried it yet with crushed dry ice? I know too much of it will cause a lot of CO2 to go into the air, but something this small of scale it might work pretty well. Only reason I mention it is it would eliminate the water drip factor.

jpnagle59 (author)2010-09-09

Danka....good job...

superior eng (author)2010-08-30

thnx man

Marwenovic (author)2010-08-10

Nice project keep gowing i'm waiting for your next project

iain010100 (author)2007-10-24

Air conditioning, just in time for November. :-) I really like the clever use of everyday objects to make that thing. Mounting the fan to a plastic lid is something I would never have thought of. Nice job.

spark light (author)iain0101002010-08-01

it never hurts to not take the risk.

bananafred (author)2009-01-22

Don't use this with dry ice in a car or small enclosed space. It could suffocate you.

xproplayer (author)bananafred2009-01-22

the smoke is just harmless water vapor not deadly at all

bananafred (author)xproplayer2009-01-23

It's carbon dioxide. From "Dry ice is solid carbon dioxide. You can make a dense fog by adding dry ice to hot water or steam. The carbon dioxide is vaporized, making a fog."

awang8 (author)bananafred2009-02-22

Yeah, that's right and if everything around you is CO2 then oops better get an oxygen mask.

tinkerC (author)awang82009-02-22

Then use normal ice. Use a USB Fridge!/ made extreme to freeze the ice.

xproplayer (author)tinkerC2009-02-22

how u make it extreme i want something like that

spark light (author)xproplayer2010-08-01

well, a normal usb will not supply enough power to make that much ice, so just get a regular mini freezer.
