I have build this smoke extractor for soldering wires, and rarely circuit boards. Since I sometimes do soldering in the field, I wanted something, light, portable, and inexpensive.

disclaimer. This project utilizes tools that can be dangerous if not used properly. Always be cautions while cutting sheet metal, and working around sharp edges. Never put your hand under any surface you are drilling, or cutting, and always use gloves and safety glasses. I am not responsible for cuts, metal splinters, or drill bits in your eyeballs.


Step 1: Parts Needed

materials needed.

-snack tin, or any metal box
-computer fan
-transformer 6-12VDC, battery, or power supply.
-tin snips
-drill bits
-drill
-marker
-screws
-tape measure
-wire grille, hardware cloth, window screen, or chicken wire

assuming you have these materials laying around, the cost should be $0.

Step 2: To Get Started

Draw in outline on the lid, and drill a hole for your snips. I used the outline already drawn on the lid. After the lid is cut, size your wire grille, and attach with glue. The grill I used is from an old bird cage. On the bottom make an outline for your fan, and 2-4 holes for mounting screws.

tip. when using tin snips, don't cut all the way to the tip.

Step 3: Bottom Filter and Feet

Original I made feet using scrap metal from the lid, but upgraded to some rubber grommets I found. The filter material is polyester snow from our ceramic holiday village.

Step 4: Done

My solder smoke fan is complete. It is very portable, and I am able to fit my battery soldering pen, wire strippers, heat shrink, and solder in the box too. The box is very effective, and can be used laying down as a soldering surface, or standing up.
just one question..... what is cleaning the smoke? All I can see is a fan in a box, in which case, why not just have a fan blowing across your work table as you solder?<br><br>If you had a small charcoal fish filter insert at the bottom, I could see it scrubbing the air, but this wouldn't be very helpful since it's just pushing it around the room, instead of scrubbing the bad fumes out of the air.
In one of the finished pictures had a piece of polyester taped to the bottom. I have long since made a polyester envelope filled with carbon. Thanks for your comment, and one of these days maybe I will post an updated picture
great idea thanks alot :_:
