WR&N IV Animation: Window Fan

This was a fun little project that adds a very subtle touch of animation. It was also quite simple, requiring only a low-RPM motor and some bits of brass and plastic.

I bonded some thin slices of styrene rod directly to the end of the motor shaft to make the fan blades. The fan body was made from strip styrene, and the grille was a tiny bit of etched brass roofwalk.

The completed mechanism looks like this:

And in situ:

The apartment building with the window fan now resides on Rick Spano's Sceniced and Undecided.
