If you solder things in your spare time or are a smoker, you know the value of having a good ventilation system. Nobody likes sitting in a room full of deadly fumes, no matter where they came from. If you don't have the scratch for a fancy fan system, why not build your own fume extractor out of an Altoids tin?
Make tells you how to do just that, and it looks simple enough for someone who's just slightly handy to pull off. If you're a complete klutz who's all thumbs, on the other hand, maybe you should just head to Home Depot.
