[sdiy] Random Voltage Generator & ADV/Cookbook

[Marcos San Miguel]

A really stupid way to get a noise source with enough
low frequency to pull this off is a AM handheld radio,
tuned to a magic 'inbetween spot', through the LPF
(Better to s/h and slew limit, but...) Not a 'module'
but hell, it works...nice smooth changes... I had seen
a schematic for a white noise generator based on a
'pinched' geranium diode, that generated some very
wide band i.e. inclusive of lower frequency noise that
would probably work well, not sure, can try and find
it if your'e intersted...
