    Here’s an astrolabe generator written on Python:

    Looking at the source code is a good way to see how the various elements are created.

    The best book I found for the theory of astrolabes and how to build them was "Practical Astronomy" by W. Schroeder, published by Werner Laurie in 1956.

    You need to use the largest piece of paper you can find to draw out the projections so you can make an astrolabe of useful size. The astrolabe I made in the photo below is about five inches across and I needed two A3 pieces of paper taped together to make that.
