    How would i go bout making a random voltage driver for a DC fan to simulate wind. The simpler the better. I have no experience or any idea where to start with random generator circuits.

    Well what you probably want is more of a random walk type simulation as wind is not pure noise and tends to follow trends (like for example a stock market.) One option if you don't need it to be random is to mix various frequencies together from signal generators. Sufficient difference in frequency between each will create a good illusion.
