Hi,
Here are a couple of projects that I've recently built. One is
a dc motor direction controller for a sculpture. When the motor
raises a stone to the top, it trips a microswitch, which
reverses the direction of the motor and the stone descends.
When the motor lowers the stone to the bottom, it closes another
microswitch, reverses the direction of the motor again and it
raises the stone. This cycle goes on continuously.
The schematic is at,

The other project was a well pump timer. There are two well
pumps that fill a cistern. The circuit toggles between the two
pumps, which stay on and stay off at adjustable times.

Both projects will be better and simpler if you use microprocessor.

As for the DC motor controller you're wrong. A micro would only give
unnecessary complications. As for the pumps I doubt it. You may go from two
to one electronic component but you'll have to program the latter. Which
requires some skills and equipment. I would use a micro for it but for
flexibility not for component count.
