So I am working on a 3D tracking interface project that I found online at (https://makezine.com/projects/a-touchless-3d-tracking-interface/here).
However, instead of using my hand to track, I want to track an aluminum ball with 2cma 2 cm radius, which is connected to ground. I am also using thin metal aluminum plates instead of the foil. I cannot
I can't get the distance that I need, which is about 35cm35 cm. My question is, how How do I increase the measuring distance of the plate to reach the 35cm at least 35 cm?
Looking forward for all suggestions and help!!!:
