After making more pcb’s to solder, I finally decided it was time to build a fume extractor. With all the spare parts I have laying around it wouldnt be that hard to contruct. I etched a small pcb for using an LM317 voltage regulator as a ghetto speed control for a 70mm PC cooling fan. The box was constructed out of various scrap pieces around the basement. With everything finished I think a coat of paint will help, and a charcoal filter from the local Salvation Army will complete the project.
