Rotator Interface I have created this page with all information needed to build your own Rotator Interface. On this page you will find the minimal requirements and hardware configuration needed to embed this in your own Rotator interface / situation. The initial design of this Rotator Interface is based on AC Rotator motors, and Analog…
