Hello All: There are several electrical noise based random number generators, but most were concieved in a time when there was a lot less EM pollution of the airwaves. There are no "magic/secret" frequencies any more. I got into time-nuttiness from an interest in Radio Astronomy, and all Radio Telescopes must be frequency agile, and all results must be screened for possible man-made interference.
The noise diode and associated circuit might be an elegant solution in a vacuum, but I suspect that keeping electrical interference from biasing the results might complicate the problem quite a lot. Anyway, it's more interesting to watch it at work on your desk than just the glowing LED on an electrical noise source!

Hi Scott: You can use a noise diode followed by a bias removal circuit to get true random numbers in a much simpler way.
