This common table fan is more interesting than you think! I took mine apart and animated how it works - most of the video focuses on the "Four Bar Mechanism" and the gears that allow it to oscillate back and forth.
The Four Bar Mechanism was a little hard to animate. I used an armature with inverse kinematics to get the 2 bars for follow the "crank." Then I created one property called "OscillateFan" and several drivers listening to it. That way I only need to animate 1 property for the fan to work!
I love making these kinds of animations. What other household objects would make a good animation? Suggestions are always welcome😎
