In general, the way you produce random noise is you take a noisy signal and subtract the pattern from it; what's left is noise. If you're mistaken about the pattern that is expected from the signal, you can wind up with something that isn't quite random, but anything below the threshold for quantum noise is pretty well guaranteed random. In any case, it doesn't actually take a very good random number generator to be effectively unpredictable without quite extensive surveillance.
