How 2 build a professional fume extractor
Since breathing solder fumes directly sometimes itches in your nose and is probably not the healthiest thing, I built myself a professional fume extractor.
What you need for this build:
a plastic box
an old PC case fan
a battery pack (12V is perfect, 9V works just fine)
a few screws.
Then you just cut a rectangle (or whatever form you like) into the bottom of that plastic box and assemble. Done. Pic related is my professional fume extractor:
