Another idea might be to mute say, the CD drive, then record an audio sample of that device. You should get a very noisy result at about -70dB but many factors will skew the gaussian distribution. Run that through a FFT, flattening and calibrating the frequency distribution, then remove any bias and digitize the output... sounds like a fun project.  :)

You could even read CRCs from randomly selected used Hard Drive sectors too, as a bit steam source.

Oooh! Good one. :)

Can the ECC data be read in windows? Prolly not.

I don't think so...

Left,

I had another piece of genius with easily getting a real world sample to use for random sequences. If you can get your hands on a TV add in card for your computer, either the video or audio output when set to an empty frequency should come pretty close to white noise.

not sure if u know but there is a counter that the processor has that according to intel a 3 ghz processor would wrap this counter once every 190 years. u could use that to produce a varient so that even if it would be predictible it wouldn't be the exact same.
