Soldering creates some nasty fumes that smell bad at best, and cause chronic asthma over time. If you do it often, you can keep yourself safe though with this portable, USB-powered fume extractor.
X2jiggy shares the elegant design on his personal site. The box incorporates a PC fan, carbon filter pad, and a small USB power supply dialled up to 12V with a cheap converter. The fan sucks in the fumes from your soldering station, and ejects them through the carbon pad, trapping toxins on the inside. The project requires a degree of electronics experience and a little bit of woodworking, but the finished product will be a great companion for your future projects.
