But, I'm the first....
The first person to post something serious to the thread, anyway.
Here it is.
I need a ducted fan that is preferably 1.5" to 1.75" in outermost diameter. Does anyone have any idea if I can get one this small? 2" would be the absolute maximum. It needs to be able to run on 1-2 cells, smallest possible. I'm looking at a space of about 2 1/4" X 4" to mount it all on. I would prefer that the duct not be more than 2" long. Any ideas?
