Like I said, it's pretty basic. Just an old ice chest with an adjustable vent on the side as an intake, and a bathroom fan on the lid for exhaust. The dryer hose is just so I can direct airflow. I fill the chest with frozen water jugs and wet towels.
Low tech, but it can drop things about 10 degrees, occasionally more depending on the humidity.
