Little project I worked on today. Made an air purifier. Twitter link, since I'm too lazy to reupload. There's a few videos too.
I want to see if it will help with the litter box smell, although adding charcoal inside the litter itself seems to have helped a lot. It was so bad for a while I had to leave the window open which I don't want to do in winter, or when it's freaking hot like today. Will also be handy to have when there's bad air quality due to forest fires etc. I still need to add the front fan grille, and think about some kind of fan controller, and then paint it. I may also just get a 9v adapter for it and call it a day, I can always repurpose the 12v one for something else. Could get fancy with arduino and add full fan speed control but want to keep this simple enough.
