Nice one, I'm making my own, but i'm not able to get some isopropanol (it is recommended), is there any alternative alcohol to use? I heard ethanol isn't as effective as isopropanol, I guess i need some with low boiling point, do I?

@Ivis92cz ethanol is fine - so is methanol. main thing is to get as high percent as possible - 90% has worked for me but 99% is better. you might be able to get 95% ethanol at a hardware store. good luck with your chamber build!

do i got to have 2 peltier cells or would just one work?

[spambutcher]

@ppsjsh you'll need two peltiers to get cold enough - unless you order a special dual stage - which cost about $60 (this cuts out the extra power supply though)

@Akaochan It´s ok, I bought 95% technical ethanol, however I have no time to try that, maybe next week, but I think it should work; anyway thanks for idea

@Ivis92cz My science teacher said Ever Clear works well too. If you arent 21 you have to get your parents or somebody to buy it for you though.

@spambutcher Thanks for your advice :)
