A generic "light baffle" box to allow air to circulate, but keep light from shining through. Very much in the testing stage. I'm in the process of building a case for a Linksys Ethernet switch I need in my bedroom, but I don't appreciate the gazillion flashing lights shining out of every side. The hope is that larger versions of these baffles will let enough air in to keep the switch from overheating.
I have constructed my Ethernet switch box, full story at: http://tomhorsley.com/hardware/solidoodle/solidoodle-linksys.html
It seems to work, but the design really needs to be fixed in a few places, so I haven't uploaded it here.
