Couldn't you use something like this on a small scale to implement a better random number generator for computers? Looks like all it would take is a tiny speaker, a thin metal plate, and something that reads that metal plate like a QR code. The tone could then be randomized by a psuedo-random number generator, and even though the shapes generated are similar, they are never quite identical. |
