This project was inspired by the Make Weekend Project (Mini Fume Extractor)
The circuit is wired just the same as the "Mini Fume Extractor" Weekend Project.
I just modified the project by taking the "mini" and making it a little larger. I used a bigger enclosure (Radio Shack Project box) instead of a mint tin, a bigger computer biscuit fan, and a push button switch.
