[sdiy] single 9 volt battery white noise source

[Dave Leith]

Thanks for the help

Reading thru the documentation for the Rainmaker seems that this would
be the best solution. Is the following really the case?

quote" Common designs use invariably Zener diodes or reverse-biased
transistors base-emitter junctions as white noise generators. The main
snag of these circuits is that a supply of at least 12V is required,
therefore a big battery pack or (more commonly) mains supply is used
as power source."
