Riley Porter created a large fume extractor that uses fans and carbon filters to clean the air in his workshop.

This past weekend I decided that I would attempt a carbon filtering fume extractor stack (at least what I called it). Basically the fumes from the smoke of many different materials is pretty bad. The idea was to make it so the carbon would filter the smoke and output clean air.

As a bonus, when the air flows from top to bottom it spins a little stepper motor fan, generating a small amount of current which lights up LEDs on a cute little robot design.
