Collection of Mathematica notebooks worked out for a variety of papers and books. Utilizes the General Relativity Tensors package from the Black Hole Perturbation Toolkit package. They have NOT been edited fully and as such probably contain quite a few errors. But it's not a bad place to start. https://bhptoolkit.org/
