This site offers true random numbers to anyone on the internet. A
radio is tuned into a frequency where nobody is broadcasting. The
atmospheric noise picked up by the receiver is fed into a
workstation through the microphone port where it is sampled by a
program as an eight bit mono signal at a frequency of 8KHz. The
upper seven bits of each sample are discarded and the remaining
bits are gathered as a high entropy stream of bits. Skew
correction is performed on the bit stream (in order to insure that
there is an approximately even distribution of 0s and 1s).
