    can anyone help me where to find a circuit diagram for a white noise
    generator that can produce a nice gentle sweeping rain sound for use
    as a sleep aid?

    There was an article in Pop-Tronics many years back. You can try
    googling of "surf synthesizer"" and see if the schematic comes up.

    Such things use a varaible filter applied to white noise. Today they
    can be made in software. I'd almost bet someone out there has made a
    PIC do it.
