Every winter its the same thing. Temperatures drop, the air gets dry and noses start running away. One thing that helps is having a good humidifier in your home. But hat about your office at work? Most humidifiers i see are pretty big and would take up too much desk space. Not to mention can be overkill for a small office. I for one sit in a little 10'x10' office. So i need a decent humidifier that is no bigger then an adult shoe box. Having found nothing that size commercially i had to come up with something on my own. Here is what i came up with.
- Empty baby wipes container
- Scrap piece of aluminum (approximately 7.5"x5")
- 20oz Dasani water bottle
- 80mm PC fan with mounting screws
- SPDT switch (any switch will do)
- 9V AC/DC power adapter
- power connector compatible with your AC/DC power adapter
- Humidifier filter
- Small peice of scrap wire ( approximately 6")
- Dremel with fiberglass reinforced cutting wheel.
- Cordless drill
- 1/4" drill bit
- 5/32" drill bit
- jewelers file set
- Tin snips
- Hot glue gun
- Phillips head screw driver
- Soldering iron
- Laying out the Container
- Fitting the top plate
- Adapt the bottle
- Wire the electronics
- Final product
Step 1: Laying out the Container
For the container we will be using an empty baby wipe container. The top of the container is rounded and makes it very difficult to mount anything to it. Rather then remove the top completely we want to hold onto it for easy access to the inside for cleaning and changing of the filter. Using our Dremel with cut off wheel we want to cut out a 6.25"x 4.5" section from the top of the container. Leave about 1/4" of material along the back side of the container. This will put you in line with the back side of the flip up lid's hinge joint.
Next we need to make a couple of 1/4" cuts into the front part of the lid. The area where the flip lid release button use to be. This is where the top plate will be fitted and helps hold it in place.
Along the left side of the container we need to create a vent. This is where the air will be drawn through the filter collecting the moisture. The plan is for the bottle to be on the left side of the container. First you want to measure about 1.5" up from the bottom then start drilling 1/4" holes into the side. The more holes you put in the better airflow you will have across the filter. I did 4 rows of 7 holes.
Don't forget to use your files or even some sand paper to clean up the cut and drilled edges.
