White and Pink Noise Source

White and Pink Noise Source

Here is a circuit board for this. I made it skinny so I could fit it onto another board I was making that had some room left. When I was building this I noticed that I had to increase the gain of the circuit so I reduced the value of R3 to 500 ohms. I also buffered the outputs as you can see from the board.
Just put pink noise into one side of the buffer and white noise into the other and voila you have 4 noise sources (more than you will probably ever need). The buffer is not shown in the schematic but it is quite simple in that its just four non-inverting unity gain buffers with the non-inverting inputs of two pairs tied together.
