OK, now that I've figured out what the pendulum base looks like, I can
see the advantage of the rotating base, namely that we eliminate the
need for detecting the end of the range of motion!
Thanks to all who helped in my quest for understanding. Now I have to
figure out if I can build this with touch sensors or if I should use
a rotation sensor...
