The CoolMachine uses a 5 Liter Garden Sprayer to create compression for the misting nozzle. The sprayer will run for about 20 minutes before it needs more pumping. The misting nozzle was obtained by removing the nozzle from one of these very cheap water spray bottles:
The original nozzle on the Garden Sprayer did not work very well because the droplets are to big.

Four computer fans is used for the fan array. These fans were salvaged from old computer power supplies:

The evaporation chamber and excess water collection chamber are 5 Liter water bottles.
Draining the of the excess water collection bottle needs to be done about every 40 minutes.
