Yeah, you wouldnt get too much traffic or content in a section like that.
It's fine in Cooling/Everything Else

Not for long....hehehehe. I am learning on how to build your own. I just bought a torch, some tubing, and compressor to practice on. I am also studying to get my EPA certification for high pressure gases. I will soon be able to purchase said gases. Once all this is done and I practice a bit, I will post up a nice big article on phase change.

Yeah, that's assuming you don't impload your computer or blow your arms off

I'd kinda like to build my own system...but I get this feeling that it still wouldn't be much cheaper than buying one...

i don't exactly know what a phase change system is composed of, but the materials (excluding said gases) would more than likely be cheaper to get/put together, mainly because of labor and other such expenses that the company incurs as a result of manufacturing...

Only thing I'm not sure of would be the compressor....

Indeed...it would have to be a closed loop compressor...
LOL, yeah the compressors used are usually out of air conditioners or dehumidifiers. Usually around 1/4 to 1/2 horsepower or so. You can usually find used ones for pretty cheap. It's all the tools/gases/labor that become expensive. If you know what you are doing, you can build one for FAR cheaper than a new Prommie.

you might have to take into account buying in bulk from companies, too. but even that still is expensiver (wd?) than buying a prommie.

Dudes... just buy a compressor like they use for nail guns and stuff.... all you'd need to do is put a tip on the end that is tiny and turn it to full blast... I know my compressor can cause frost on a glass and if I leave it in one spot long enough it will start to freeze the water.

That sounds like a thread for the Experimental Cooling Section.

I know as much about phase change as I do women. NOTHING You could make a guild about them and I would read it. Then decided if I wanted one. Women good yet very complex, phase change good yet very complex.
oh.. for those that don;t know what phase change is... try this...
open your mouth and breathe on your hand... like you were going to fog a window... feel how it's warm?
now make a tiny opening in your mouth (smaller than when you whistle) or get the front part of a retractable pen and blow through the big opening. ... the air coming out should be cool.
Now for the basic physics. When you compress a gas (like freon in older refrigerators) you add energy to it. This causes it to get warmer (heat is actually energy) when that is released at high pressure the energy rapidly dissipates. Because of this change in state from high pressure to low... it wants to maintain balance so it sucks any energy it can out of whatever the compressed air touches. This is a phase change...
another test... take a can of compressed air like you use for blowing out your case and turn it upside down... when you blow out the liquified air it VERY rapidly expands... causing frost.
