A simple white and pink noise generator could be constructed with the help of a single transistor and a Zener diode. The 10 volt Zener serves like the noise source and it furthermore stabilizes the operating level of the transistor. Putting a capacitor C2 at the indicated position will convert the output from 'white' noise to 'pink' noise.
