“One of the Youtube viewers made a comment a few weeks ago asking about my rotator project. Their comment inspired me to finish it. This project is a 3D Printed Satellite antenna rotator. Specifically made for Ham radio and the common Arrow antenna (made from arrow shafts). I opted to make it bluetooth. Total game changer! The first version of code running on the Arduino will work with some of the Yaesu GS-232A rotator commands. This means it should work with popular sat tracking programs. Working really well. I have a few more modifications in the works and I want to get some contacts done using the new setup. Once done, and it looks good, I will upload the stl files to Thingiverse and do an assembly video.”
