Heh heh heh...Frugality inspires Creativity? I know a
few people that should have that on a bumper sticker.
Maybe I'll get one of the ARRL books too... but
designing the PCBs isn't the problem. I'm talking
about the circuit design part itself; for example,
adding some hardware to null the offset of a
wheatstone bridge type strain sensor (part of a
USB-enabled bathroom scale). All I remember about the
Wheatstone bridge was what I read in my Radio Shack
160-in-1 project kit before skipping over it and going
to a circuit that had flashing lights or made noises.
(Hey, I was only 12. :) ) A resistor, pot, and +5v was
what I eventually went with, but at first I had
visions of software compensation or using opamps to
zero it. Oh foolish me!

Will do, thanks for the advice.

> Hence my point about THOUGHT being important.

Yeah, in years past I've jumped into projects without
thinking too much and wound up starting over. That was
before discovering the immense value of designing
something first instead of trying to build and design
at the same time. ;)
