DIY-WB Output Voltage Scaling

[Bruce]

FWIW,
the decison to go analog on the DIY-WB was to keep it doable for everyone.
Digitial should be an outgrowth of it, but that also takes it to the stage
of being for the few rather then the many.
  Heck look at all the comments about soldering, never mind PICs and Stamp
programming.
