FlexiFumeFan

Soldering fume extraction using an Ikea LED lamp and a small PC fan


This project is also on Hackster.io

Soldering has some nasty fumes from the flux as it burns off. I built this project before I got my fancy Hakko Smoke Absorber (which is great).

If you have an IKEA LED flexneck lamp and an old small PC case fan (I think the one I used here actually came from a HD enclosure) you can build a DIY fume blower-awayer. Neat!

Also, InstaMorph is amazing and you should just go buy some just to have around the house in case you need it quick. It's like the duct tape of mold-able thermoplastic.

Here is the diagram of the system System diagram

An actual fan! This is what I was using. It actually moves too much air. Sometimes parts get blown around. flexifan actual fan

Assembling the lamp/fan

Tiny soldering job to extend those little wires. flexifan wire extensions Added some heat shrink to the leads... exposed wire is not cool. flexifan heat shrink I used some instamoprh to mount the fan in the opening of the LED light. flexifan instamorph flexifan instamounted flexifan instamounted side
