Thanks for checking out my project . I'm new to SF and there's a lot to do so please be patient. The H1 as I call the first prototype is doing well. I added a target id of 255 to represent the sun and coded an exception for this in the aim routine to enable solar tracking instead of heliostat operation. I'm working on getting some web pages up as soon as possible to help explain the software, hardware, and mechanical aspects of the project.
