Depending on what you want it for.. use google images to find white noise generator.

I know it's not in the spirit of the question but if you were building some sort of networked device you might be able to get your random numbers from a website like this.. http://www.random.org/

Gambling machines use fluctuating dark currents to generate random seeds for a pseudorandom number generators.

random.org also a source of random numbers.
