This is a real simple, but effective, fume / smoke extractor that I've been using for quite some time now. Thought I'd share it.
This makes a great gift for a father who smokes, and if he's a DIY type of guy, just gather the parts download this instructable,and give it to him as a kit.
Step 1: Gather Parts and Tools
1 Empty (Betty Crocker) Frosting container
1 2.5" , 12V Fan (got mine from an old scanner)
1 12v Power adapter
small piece of Kitchen Exhaust filter mesh
Wire cutter / stripper
Step 2: Start ( and Finish) the Build.
1.- Grab the cap and use your scissors to cut a circular hole around the edges of the inside o ring that is in the cap.
2.- Turn the container around, and draw three u / v shaped, equally separated guides to cut out the exhaust holes. (see pictures for clarity). you should end up with a "peace sign" looking back-end.
3.- Use a magic marker to trace around the filter mesh using the front of the container as a guide (see picture)
4.- Insert the cut out circular filter mesh into the inside of the cap(cover).
5.- Place the fan into the container until it hits the bottom, it should be a snug fit.
6.- Put the cap with the filter mesh back on the container.
7.- connect the wires from the fan to the power transformer and insulate with electrical tape.
8.- Plug it in and enjoy a smoke free environment.
Hope yo liked this easy to build smoke extractor.
Step 3: Smoke Extractor in Use and Going Further
Here you can see the extractor used as a "smokeless ash tray". You can also use it as a fume extractor when you are soldering.
Goinig further , you can add a switch between one of the cables to turn it on and off, I have mine connected to a power strip that I turn off when I'm not working.
You can also insert an air freshener, or an active carbon filter inside the container to enhance the operation.
if you can't find a small fan, just find a cylindrical container that fits the fan you have, and adapt!
