Picture of Make a Small Air Filter/ Fume Extractor
Make a small air filter out of a few fairly common parts for when you are soldering or for if you smoke (filthy habit), also, if you use a lit fan it makes a cool night light for younger children. This is my first Instructable so please, constructive criticism only. I already had this built so the pics are of it already assembled, but I figured it would be nice for the dead computer contest. I don't expect to win but I thought it would be something fun to make.

WARNING- This does deal with some minor electricity, I seriously doubt you could be injured but, regardless, YOU are responsible for YOUR OWN actions.

Step 1: Materials

Picture of Materials

-Old speaker, preferably one with a tweeter
-Computer fan, doesn't need to be lit but I had one and it looks cooler
-Toggle switch (optional)
-Maybe some wire
-Activated carbon (buy at a pet store in the fish section)
-Window screen
-12 Volt DC power pack


-Dremel, X-ACTO knife, or similar cutting tool.
-JB-KWIK Adhesive 
-Heat-shrink tubing
-Sabre Saw (optional)

Step 2: Take Apart the Old Speaker

 Take everything out, save nothing but the housing itself and the wire jacks in the back. The back on mine was held together by some sort of adhesive, this is where you use your dremel or X-ACTO knife.

Step 3: Put In the Fan

Picture of Put In the Fan
 I had an 80mm computer fan that fit perfectly in the large speaker hole. Use your JB-KWIK to mount it in. Make sure the fan is facing to pull air IN to the speaker housing. The hole where the tweeter was is where the clean air will come out.
The only suggestion I can make is to seal the top front hole, and add a hole to the rear.  You should also find a way for attach the activated charcoal filter to the fan, maybe with a 4inch piece of PVC pipe to force the air to actually go through the filter. Unless you're actually forcing the air to go through the filter, it'll take the path of least resistance and go around it.  Otherwise, it's a brilliant idea for dead speakers.
the activated charcoal is something

How loud is that thing?

I like it.

Would something like that be usefull in a kitchen or bathroom odor type situation, or is the airflow of it too small?
It appears that his is attached to his computer so putting it in the bathroom wouldn't be the best of ideas. If you were to put it into a bathroom you would have to find a different power supply as the power supply listed requires a mains adapter.

 It just has its own DC power pack, I just took the picture by my computer.
Yes, I am aware of all that.  I was just curious as to the effectiveness of a unit of that size as a room deodorizer.  :-)

 Mine isn't loud at all and it does work okay in the bathroom, but its air flow is somewhat limited, it isn't intended for large areas by any means.
