We Never Know
No Slack
There are all kinds on youtubeI've been thinking of how to make some "usable and cheap enough" device to cool a bedroom at night. I probably have it figured out, but by usable and cheap enough I mean a styrofoam cooler with dry ice and copper tubes (with fans at one end to draw air through the tubes and blow it out) inside with some exhaust tubes leading to a foam board that's got a decent temporary seal around it anf the window.
However, I also feel this is a project where I learn there's actually a lot to it. Like two things I made that also involved making wheels. Turns out theres more to wheels than just sticking them on something you want to move.
