An interesting rotator interface that interfaces a pc to a rotor or rotator controller, emulating a Yaesu GS-232A/B and Easycom protocols, made with Arduino

This is an attempt to build an Antenna rotator controller using Arduino Mega 2560 with a nice user interface showing the actual position of the antenna.

The Antenna Rotator Controller is unique in that it senses, displays, and controls to the earth's true magnetic field. The compass sensor, mounted in a waterproof enclosure, is attached to the mast and sends its signal to a microcontroller

Rotator controller, azimuth & elevation control of rotators (automatic antenna turning) based on commands from computer. A project by Pavel VACHAL and OK1DX - KF9VM

Inspired by Milan OK7GU, the goal is to build an universal antenna controller - for different types of rotor, different motor, encoder

Aduino-based Amateur Radio Antenna Rotator Controller that can emulate the Yaesu GS-232A or GS-232B interface by K3NG

This Satellite Antenna Elevation System project involves mounting horizontally polarized Yagi antennas on a fiberglass reinforced polymer (FRP) crossboom. A Yaesu G-800DXA azimuth rotator is in place, requiring only an elevation rotation system. Elevation is controlled by a 12VDC linear actuator connected to a U-bolted arm on the crossboom, rotating within a DIY bearing arrangement. Common handyman tools suffice for assembly. The setup includes FRP crossboom, aluminum tubing, PVC couplers, nylon camshaft bushes, and a K3NG-based controller for azimuth and elevation control. Detailed guides and resources are available online.

The Beam project offers various features for controlling antenna rotators, including support for 2 or 4 line LCD displays, software or hardware clocks, open collector drives for azimuth and elevation control, and internal calculations for tracking the sun and moon. It can also track satellites and supports "Flip Mode" for inverted antennas. The 4-line version provides detailed readouts while the 2-line version offers a more compact display. New versions now support PWM and I2C H-bridge modes for adjustable speed control at the end of a move.
