So instead of facing the sun, you will be facing away from it. The screw eye should hence cast a shadow on the cardboard square and all you have to do is aim that shadow on the cross. I attached a pdf with a A4-size quadrant with 15 arc minute intervals. It should fit an A4 and could then be pasted on a piece of plywood. If you prefer larger size I should be able to create everything up to A0 (and create finer scales).
