I can mount it on a platform that allows me to manually position it but I'm interested in fabbing some sort of mount that will allow it to oscillate through 140* or so.
Any thoughts?
1. Secure the unit to a heavy duty lazy Susan
2. Get some 6-8 mil visqueen, about 6’x8’
3. Duct tape the set of 6’ edges together, forming a tube about 2.5’ in diameter
4. Place one end of the tube over the fan exhaust and secure with duct tape.
5. Build a 77”x14” frame (edit: inside dimension) from 2”x2” and place on the floor.
6. Place the unit about 5’ from the frame along the perpendicular bisector of the frame’s length
7. Duct tape the bottom edge of the free end of the tube onto a Roomba.
8. Place the Roomba in the frame and turn it and the fan on.
The Roomba will travel back and forth within the frame, pulling the end of the tube with it.
Air pressure should force the fan unit to rotate on the lazy Susan, keeping the tube from kinking.
It would work better if you were to make the frame curved with a 5’ radius, but there is only so much a person will do to try to save the $20.15 for the fan in cams2705’s post....
