The portable clock/alarm clock sparked our interest because
it’s a very typical object in our society that resides in just about every
home. Even with the growing use of smart phones for clocks and alarms, physical
clocks still surround us day to day and we had never given much thought to how
they actually operated. Before we took apart the clock we guessed about a very
simple system inside the clock. It turned out that we were basically right as
only a small number of parts make up the machine. The battery starts the
operation by enabling the on/off switch, which drives the motor to control the
clock hands. The clock hands are also operated by the alarm setting and the
manual hand controls. Although the interior was simple, It’s enlightening to
discover how exactly this basic object functions. Next time though, we may pick
something a little more complex.
