Hey! I have write some comments in your pull request. The next improvements is fine, because the V3 rotator is designed in order to mount dc or stepper motor (with change of the motor mount), we want to reduce the interference of motors and to have feedback from position of antennas.
For now we design the mechanical parts of V3 rotator (last 3 days) and we do not have a clear plan about the electronics.
We buy a dc motor like this DC motor, in order to test it with the V3 rotator. This is not the final choice, we will compare different types of motors (dc or stepper), with different characteristics in order to achieve our specs and a reasonable cost.
The V3 rotator is necessary to have position sensor, that measure every time the position of antennas. A good choice of it, is the AS5048 or AS5040 , which has different interfaces like I2C, SPI, PWM. The resolution of the sensor is 0.05deg or 0.35deg, but in the elevation axis we do not consider how to mount it. Also the price of the this sensor is not to high. An alternative method to measure the angles of two axis is planetsofa position sensor with pot. Has anyone try to use IMU? Do you have other ideas about it?
Additional sensors which checks the conditions inside and/or outside the rotator box is under consideration. The temperature sensor is a good idea, also a humidity sensor is useful, other sensors that you believe is necessary to add?
To reduce the interference of the motors and the electronics the EMI shielding and this look good ideas, other ideas about it?
Stay tuned for updates !!!
