The purpose of the pocket-sized fume extractor is to remove all harmful fumes from the air that are created by smoldering solder.  The fume extractor was built using very few parts and simply gets its job done wherever and whenever you need it without requiring an electrical outlet or large amount of space.  

The fume extractor uses a 9v battery to power small 12v fan i purchased from Radioshack and contains only two soldered connections, and so it is an excellent project for anyone who is just learning to solder.  Instead of containing an on/off switch, i built the extractor so that the battery is plugged into its body in order to turn it on while also acting as a stand for the extractor itself. 

How does it work?  The small fan sucks air containing fumes through it, and then blows them through a carbon filter that is glued in place in front of it.  This effectively removes all dangerous chemicals that the fumes contain from the air around you as you solder, thus saving you from a headache as you work. 

Step 1: Gathering the Parts and Tools

For this project you will need the following parts:
-9v Battery (any brand)
-Hard plastic 9v battery clip
-Small hinged acrylic case (mine was bought with shark teeth in it, it's 55mm by 44mm by 20mm) 
-12VDC Micro Fan (http://www.radioshack.com/product/index.jsp?productId=2102824&filterName=Brand&filterValue=RadioShack#tabsetBasic )
-Weller WSA350F Carbon Filters
-Red and black heat shrink tubing (optional; covers your solder connections)

You will also need the following tools/items:
-Soldering iron and Solder
-Super glue
-Fine point Sharpie
-Sandpaper (i used 80 grit)
-Heat gun (if using heat shrink tubing)
<p>Great instructable! I made mine using Lego for the case, hot glued together. Basically 2 Lego frames, front one to hold the fan, back one to hold filter. I didn't have carbon sponge, so I filled the back frame with loose carbon, contained by gluing a fine mesh on both back and front of frame to contain it. This was done prior to joining the fan frame and the filter frame together with hot glue. I wanted to add the battery upright as you did, but it wanted to overbalance :-( Must not have aligned the Lego all that well. I can also use heat gun to soften the glue on the back, remove the mesh and replace the carbon as necessary.</p><p>Works great!</p>
<p>Looks great with the legos.</p>
<p>how to get lots of computer fans for cheap: make friends with people from computer shops and you will get loads of computer fans just for buying him lunch.......</p>
<p>Really nice! You can also name as a smoker. And yeah it's portable..</p>
Nice. It's not the most powerful thing, but it sure is portable :)
Your 'ible looks real nice. Well laid out and easy to follow.<br>I think the only change I would make is cutting the hole slightly smaller on the hinged lid and insure that the fan is glued in place so that it blows through the lid, so that the carbon filter could be wedged between the fan and the lid to keep it in place. This would make it easy to change out as needed, without having to rip it free of the super glue.<br><br>Cheers
I would also put a switch, but I just really like switches, so there's that.
This is great! Of the experince I've had with industrial fume extractors, this operation is reversed. The fan removes the fumes from the air by sucking the fumes into the filter, and the clean air exiting through the fan.
I have one of those cases too! i got shark teeth in it one of the times i went to hawaii.
Catch 22, you need to solder, to protect yourself from solder....
great solution for some, but not for me, I guess you could call be a smoker. I smoke 2 ft. worth of solder fumes every day.
I was just accepting my slow, painful, chemically-induced death, but I might finally build one of these since its so simple. The 9V battery as a base in pure genius, man. Well done.
nice and simple, I like it.
Nice design, I've been thinking about building something like this. You may have inspired me to get off my duff and get to work!
