Our little electronics buddies - the R's, the
C's, the L's - where would we be without them? Making batteries
and watching frog legs twitch, that's where! Not much of a radio to be
made from the hindmost appendages of rana
pipiens, that's for sure. So let's take a look at
electronic components in admiration for the thankless job they have of
shuttling electrons around in useful ways. After all we only notice them when
they…what's that smell? I gotta go!
