Manual Controls

 

Joystick

Pendant controller with vintage analog potentiometer joystick

 

Handwheel

Handwheel prototype. The final version would have two handwheels, for pan and tilt axes.

 

Rotary encoder and quadrature decoder circuit prototypes.

7400-series TTL logic was used to handle the high pulse rates from the 2500pulse/rev encoder in real-time.

The particular circuit shown above provided scaled step and direction signals to drive an appropriate stepper motor driver directly.
