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.

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.............................

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

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 ?

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

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.
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.

its portable! you can use in car with an Ipod car charging usb thingy from apple!
Or you could simply roll down the windows.
no it does not help in saskachewan

how many trees have you found so far?
i lived in edmonton for 6 months, not one tree
Oh. I don't imagine this cooling a whole car, though.
2 or 3 mabey, also try running the fans (of the car) with no heat or a/c
Why not the real air conditioner that comes with the car ventilation system?
cuz its broke
Because you can use this other places, like an airport, or in a car with a broken AC unit.

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.
ya thanks for ur imput. Ive i almost did that then i was like oh ya.
put a cup under the tin

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

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.
try putting a drip catch under the container
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.

i recommend adding some salt on the ice

thanks i made mine for my car
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! =)

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

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.
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

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.

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

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.
it never hurts to not take the risk.

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