Any way you can rig up some motion sensor LED's or something? Like only blink when "they" are out and moving? :twisted:
Maybe a small parabolic audio dish...

I will guinea pig it. Worst case I end up with a fillable hole in the bottom. The sensor pretty much sits on the bottom "plate". Not hard to test, fire up the fan then get a stogie going, then put it beside the shield at the top and work down, if the smoke moves into the sensor near the top at all, its working....

I've been wondering about the bottom mount fan blowing downward/out. I can't imagine where it would draw air more than 1 or 2 plates above because the fresh air would be coming in all around the sides. No suction left to reach up to the top so air up there doesn't move (with no breeze or wind). Where a fan up top would draw out rising air so all air moves.

Once I get 12 volt to it for the fan, the lighting possibilities are endless. perhaps leds flashing around this sign.... Andrew
ps: is it possible to resize images to make them smaller with the bb IMG tags?

Your sensor being mounted near or on the bottom is ideal. I shouldn't have ass u me d it was near the top and a 12v fan should have no problem pulling air down across it being that close. It will still be interesting to hear the results of your "stogie" test if you don't mind posting when finished. :grin:
