/diy/ - Do It Yourself

1. is this cooling system feasible? will it be worth the money as I want to build it at least a month before I get chinchillas
2. what is the best coolant with regards to cooling capacity and low humidity? how can I put it in and close the system?
3. is there a more efficient/less-cluttered way to make this?
4. how do I make the automated temperature control work? I'm not tech-savvy or good at programming so arduinos and stuff go over my head. can you give a simple way to do it please?
5. what sort of parts will I need and what sort of costs am I looking at?
