/diy/ - Do It Yourself

>>868022
Not the way in your pic. Expensive, and doesn't do much more than make your room humid as shit.
Get a fan or something.

>>868022
AC. The icebox fan only works if your room is isolated from your kitchen.

>>868025
He has a fan, it's on the icebox.

>>868022
A couple of big box fans do nicely.... or an AC unit. These things can be found cheaply at walmart or pawn shops (check both, sometimes pawn shops can actually be higher than walmart for something used)

The key with box fans is to get a draft blowing through your house or apartment. Open two windows or doors leading outside on opposite ends of your place, put one box fan blowing in by one window, and then a box fan at the other end of the house blowing out. It makes a nice cool breeze through the whole house.

I had no AC one whole summer and two fans blowing a cool breeze throughout the house almost felt better than AC, like AC but with fresh air.

>>868022
How close is your car parked?

Insulated Duct from window + ducted fan

Sorted

>>868022

Two 20" box fans should be about $40.

They'll serve you well.

Bonus points if you buy washable filters for them.

>A fan makes a room colder

A fan doesnt do shit retards, it only moves air arround

>>868022

OP if your room is fucking 38 degrees get a fucking AIRCONDITIONING

I mean, if you live where I live, where it is 30 degrees maybe 5 days in a year, i imagine it might not be worth the investment

but if its fucking 38 degrees, what are you waiting for??

>>868130

>>868165
is that thread archived anywhere? I know it was up for like, a year.

>>868022
Whatever you do, do NOT use dry ice with one of those. It may be colder, but will fill the room with CO2 and suffocate you.

ONLY use regular ice.

>>868148
>it only moves air arround

Which makes you cooler. You learned about convection in high school science. It doesn't make the ROOM cooler, but it cools you off.

>>868022
>how to cool down your room

>>868148
It cools the air if the fan speeds up the movement between two temperature differentials.

>>868148
>A fan doesnt do shit retards, it only moves air arround

Evaporative cooling. Aka what your body does naturally.

OP- get a fan. point at self. drink lots of water. You really, honestly, can't do much better then that without an AC unit. Or dumping water on yourself.

>>868179
works great for pest control though

>>868179
We're talking about a house, not an airtight coffin.

>>868022
Eat the ice instead. Does no one else seriously do this? You're not going to get cold, but it'll certainly take the edge off.

>>868212
Underrated idea. The efficiency of the energy transfer from [Your Body] to [The Ice] is a fuckton more efficient when the ice is inside your body. All that stupid fan setup does is waste the cold [physics - heat sinking capacity] of the ice on the air around you.

>>868209
It's airtight enough without all the windows and doors open to suffocate you, and if you've got all the windows and doors open while trying to cool the house, you're a retard who deserves to suffocate.

>>868022

>>868217
No it's not, because most of the cooling comes from the ice evaporating, not melting.

If you eat it, it melts then goes down the shitter, never getting a chance to evaporate.

>>868220
Dry ice is sold in ~10lb bags (4.5 kg). The molar mass of CO2 is 44 grams which means there are roughly 100 moles in a bag. The molar volume of gases at STP is 22.4 liters. 100 moles * 22.4 liters = 2,240 liters or 2.24 cubic meters. That's only 5.6% - 7.5% of a normal bedroom, not to mention CO2 is heavier than air.

>>868250
No wonder my hands never get cold when I hold ice! Thanks anon!

>>868165
is it compatible with imitation crab meat?

>>868283
The OSHA's maximum safe level is 3% (30,000 ppm); lethal concentration (death in 30 minutes) is 10% (100,000 ppm).

>>868294
>Golly gee wilikers, my lungs are on fire and I'm vomiting all over, must be allergies!

But again, in all seriousness:
CO2 is heavier than air
The room is not sealed

>>868283
Meh, you're so smart and good at math, look up water's latent heat of fusion, latent heat of vaporisation and specific heat capacity, and run the numbers yourself.

You'll see you're wrong, and why.

>>868025
>get a fan
>when the air temperature is above body temperature, and wind chill works in reverse

OP here
I live in the philippines and it reaches 30-34*C here in the city. But in my room / the whole second floor I get like 36-38*C of room temp. Ive always opened my windows and used fans but its quite dusty. I can't invest for an AC yet plus electricity heres quite costly. I temporarily stay downstairs since all the cool air stays there but I dont have any space for my things there, it's our kitchen.

>>868433
the whole place just really gets hot in the afternoon because of the roof absorbing all the heat

>>868434
How about an attic fan?

>>868433
Get copper tubing and do the following:

Get a large bowl of ice and water,
put one end of the copper tube into the water,
Mount the copper tube around the backside of your fan,
Put the other end of the copper tube above water level in the bowl and suck on this end until you got a steady stream

>>868540
this shit right here works
10 dollars and works amazing
gonna try with warm water later the winter

>>868604
It'd be a bit more silent and efficient if you mounted the tubing on the back of the fan but the mount itself looks solid.

>>868193
>>868205

exactly
you wont make the room colder which is what OP asked for

>>868022
XD

Use a fan and spray yourself with water

put frozen bottles of water in front of a fan.

this should give you that cooling effect your looking for.

Solar Panel fans. Starts up as the sun arrives. You get the fan part in the shade. The water which is always a heat reducer under air flow - inside something metal, that is not exposed to the outside. Coke cans etc.... But if you can make it thinner so air passes quicker then that's better.

One of the best ways to reduce heat in the home is the "stack effect airflow". Google it, be surprised. A vent in the roof makes all the difference. At least under the eve of the roof at the highest point by the crown.

>>868022
spray the outside walls with water, it will cool the house when it evaporates.

White sheets in front of the windows will reflect the light and heat from the sun but are only useful before it gets hot.

Opening windows at night is also an option depending on how hot it is at night.


The evaporative cooling can also be used to cool yourself, like said before you can just spay yourself and put a fan down. It will keep you cool.

>>868022
Stupid question, would something like this work better if it used dry ice?

>>868285
>imitation crab meat

>>869038
No, that would kill OP
and anyone who tried it
>but it would turn into water
no
Dry Ice is frozen CO2
when that shit melts, it turns into the gas you exhale
you'll asphyxiate to death

>>869046
>that webm
FUCKING WHY

>at least now I can troll /g/

>>869051
dell tech support
anyways got it from a pc gore thread on /g/ as well as pic related

>>868022
Order a $150 windows AC from Amazon.

>>869051
only thing I can think of is that these are computers that had confidential information in it, like those of the guardian which had documents edward snowden leaked. there's a video of a chief editor having to smash his notebook (or the one he's been given, IDK) in front of police officials.

>>869057
Nah, it's so dumpster divers won't get free computers. If they were trying to destroy data by slicing up the motherboard, it's no wonder snowden was able to do that.

>>869105
>>Hey, I know how to stop those pesky dumpster divers!
>What, donate all the good shit to one of those charities?
>>No, we'll cut the motherboard in half!

>>868317
I'll pass. Thermodynamics ain't my thing and figuring body temps sounds like a pain.

>>868283
Correction, I should've used SATP which is 24.8L

>>868022
I made one of those last summer. Works well for a small room, but anything large will need something bigger.

Ice surface area is the key to getting really cool air and water is your enemy. If you can find a way to drain the melted ice you will get a more constant stream of cold air.

>>868022
Also OP you're a pussy,38 c is nothing.

>>869046
Actually I've done this with dry ice and it wouldn't be enough to kill you unless you bought a couple hundred dollars worth of it.

>>868318
That's not how it works, retard.

>>868022

Evaporative neck cooler
Marble slab
Sarongs
Handheld water mister used with regular fan
Succulents or high water content plants plus grass instead of sand surrounding your house

But really, if you have AC to your house, install AC.

>>869057
So, those are Hillary's email servers?

>>868022
Move to a free country where 38 degrees is actually quite chilly

>>868022
Bite the bullet and spend $100 for a window air conditioner and move on with your life.

>>871734
pretty much, or one of those portable ones so you can put it in different rooms

>>868285
did that guy ever reveal what he used all of it for?

>>869114
>donate all the good shit
>good shit
>being dumped

>>869046
wha... what is going on in this webm?

>>872291
Just because something is being replaced does not mean it is worthless. A company might upgrade hundreds of PCs that are only a few years old for endless reasons, PCs that would be useful in schools, libraries or even distributed to homes as part of a program. More often this "ewaste" is wrecked because it requires no thought.

>>872606
Sometimes you're lucky and goodwill gets them, then sells them as barebones for dirt cheap.

>>869044

wow, reality is awesome, I could not have made up that craigslist ad with all the drugs in detroit...

>ideas how to cool down your room

move your room underground.

I live in Arizona- it was 48C a week or so ago.

I always chuckle at these icebox fans. Luckily it's such a dry heat here that evaps work great- evap-cooled box fans were kind of a thing around here a decade or so ago, I remember us having a real clunky one when I was a kid.

Best option is always AC- around here we get a discount on our energy bill if we keep our usage low between 10am and 8pm, so I always stick it to ~27C during that time and just deal with the heat, then drop it down to about 25C when it's the "cheap time" of the day. Any cooler than that and I feel cold.

>>872623
I used to go to a class in highschool that just taught us how to refurbish old computers like this. We'd get one or two fixed a day and send them to non-profit organizations.

>>872601
Destroying computers, obviously.
Honestly, though, you could probably still salvage most of the data off them.
I play it safe and thermite my hard drives when I get a new computer.
