Step 1: Parts and Time
Parts - Tools
- Cardboard box of some sort. Just big enough to fit the fans. I chose an Optorite DVD burner drive box I had lying around.
- Fans. I chose 2 blue LED 120mm fans I you can pick up at www.svc.com or www.newegg.com on sale from $10-15.
- Filter. I first tried cutting a whole house filter but it is wavy and has a metal guard so I went back to home depot and found Vent filters for about $8 for a 12 pack of 4 in X 12 in filters.
- Box Cutter or x-acto knife
- Screw Driver and included fan screws
Improvements for my next version.
- Add a switch to turn it on and off.
- Add a Fan speed control.
- Add a LED kill switch or use fans with no LEDS (Hard to fall asleep sometimes but is good for a night light)
- hook to a 12 volt DC to AC power adapter so you don't need to run a wire from the computers power supply.
Step 2: Sizing and cutting
Then I cut out both holes for the fans.
