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.
