Just finished attaching two oscillating fans to the eave of my back patio. I will work on tidying up the wiring tomorrow. I also have a pedestal mount oscillating fan (electrically) tied into the two on the eave. All 3 come on when I flip the switch plugged into the extension cord. These are handy little switches. I have a second one in the garage I use to turn on an overhead shop light.
The increased wind flow in back will help mitigate some of the stifling conditions that always come with the warm season here.
The two smaller fans were only $23 each from Walmart. The larger fan I've had here for a while.
Next item back there is to try and re-direct the exhaust from my AC condenser out from the enclosure. That should be an interesting project....
