[sdiy] LFSR digital noise source

[David G Dixon]

I've built quite a few analog white noise sources, and I've never selected
transistors, and they've always worked perfectly.  Not sure why.  Have I
just been lucky, or is it actually pretty idiot-proof?

Hi Colin,

Mostly for repeatability. Analog sources have more variation. And thus 
you will have to select noise transistors/zeners. Not a huge deal for a 
one off noise source.

Best,
