I started a thread offering to make some sound effects, nature sounds such as rain, wind, storms, and some other ambient sounds such as insects, animals, and birds. I have other sound effects that I have recorded, like elevators, doors, and things like that.
I created the sound of a lever for a previous project that never got anywhere. It matched a viewpoint animation of a lever being pulled back and bouncing forward after being turned loose. You can listen here:
