Raph writes “While reading the make magazine blog, I visited a webpage explaining how someone built a fume extractor: Ultra cheap fume extractor. I immediately decided to build one too. I built mine a little differently. I did not want to have the fan right in front of me. Too noisy. Instead, I installed the fan in a closet and use a long vinly duct that goes to my desk. Now the risk of inhaling the fumes directly is greatly reduced.” Link.
