The Apple II joystick is just a pair of potentiometers (variable
resistors) each of 150Kohm maximum resistance, arranged with a
mechanical linkage so that the stick turns one for motion in the
X direction and the other for motion in the Y direction.  There are
also one or two momentary-contact pushbuttons.  The connections
that need to be made to the joystick connector or peripheral DIP
socket are described in the Apple II technical reference manual.
You would be better off buying a joystick (both Apple and Kraft
make good ones) unless you just like to work with mechanical widgets.
