[sudo-discuss] mx brown switches in salvage

[Jake]

we have a duct fan, it's under the laser cutter to the left of its cart 
last i saw it, it's a beige and blue metal box the size of a small TV/VCR 
combo, and it has two 4" duct things on the back.  It would need some 
modification to work with the exhaust duct we have (cardboard and duct 
tape or something from the hardware store or a cut-up plastic bucket)

and then its inlet can be ducted to our acrylic fume hood box thing, or to 
whatever we're trying to ventilate.

also don't forget someone should go on the roof and reposition the top of 
the duct in the skylight thing so it's centered over its hole, so it 
doesn't leak back into the room like it does now.
