# List of present and future topics

This is a list of topics that I find interesting and/or important. Most topics are listed in the order that they are easier to learn. Earlier topics are generally part of later topics. I will try to cover most of them. I am also adding the part numbers/descriptions of particular components/tools I have next to the topic.
