I have been working hard on the tracker, I built it together, so no more breadboard floating around. I found some problem with the auto ranging circuit, so it is not working yet. I also had to change the rensistance ranges, so in this state I have 5 ranges, but I would like to upgrade to 8 or more, if it is possible. I have to work on a lot of things still, so it is some photo, where is the project now.
