For example, one classic mistake I find in my consulting practice is the use
of too high impedances in low-energy sensing circuits. A little moisture, a
little dirt, and it'll be on the fritz. The right way is to use low
impedances and then pulse-measure. But it seems universities don't teach
that stuff anymore.

They're concentrating on "low power" (what every laptop needs, right?) so the
students naturally gravitate towards high-impedance designs...
