I decided to re-purpose a small AC-powered air cleaner for use as soldering fume extractor.
Just hooking up a hose (so that the unit would sit off to the side or on the floor) would be lame.
So, I thought of a way to tech it out -- automate it!
*EDIT* Ignore most of the following (it'll still use a controller). I explain in the discussion.
My idea is that it would be plugged into a controller, which would have an IR sensor to watch the solder pencil for movement. When it senses movement, it would run the cleaner for ~30 - 90 seconds. Also, any movement during that time should reset the timer; thus, the cleaner will constantly run while the pencil in being used, then shut off a short time after last movement.
