Oh man, thank you so much! I appreciate that! Definitely spent some hours pacing around my apartment wondering why I'm completely inept. Those are peristaltic pumps traditionally used for medical dosing.
I actually made a setup for an automated watering system not too long ago and I used submersible aquarium pumps for that. These were definitely easier to work with, cheaper, and much smoother than the peristaltic pumps so check those out. Happy to help you along on that project if you need help!
I bought a couple of these awhile ago for a similar project: https://www.amazon.com/gp/product/B010LY7P3Y/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
You can get them from aliexpress, but there are also a bunch on amazon in the $5-10 price range from various resellers. Mine works great!
I made my own large scale swamp cooler based very loosely on figjams unicooler. I made a box out of 1x2 lumber and lined it with plastic shower surround material then caulked the inside. Cut a hole on one side for the fan and cut a hole on the other side for the pad (air intake)
I used this fan
And this pump
and this pad
I think one place where figjam is just flat out wrong is that he uses too large of a pump. The entire premise of a swamp cooler is that the Ideal Gas Law states that as the phase change occurs and the gas expands, the temperature of the gas is lowered, however for this to happen you want rapid evaporation. If the pad is too wet, it will interfere with evaporation due to cooling the pad itself.
