There are two categories of courses at Contextual Electronics: Projects and Skills
This is the result of having developed 3 different versions of this course and seeing how each is used regularly. The thing that popped out most frequently was the repetition of certain tasks. Things like soldering and layout and choosing parts. Each project has these similar elements. If each project was taught from first principles, each of these repeated elements would need to be explained each time.
Instead, we realized that these are in fact Skills. The mechanics of various actions that allows a member to build a project. So we split out the skills into various libraries, libraries which are also sorted by the tier of each user. An “apprentice” member does not need to dive in as far as a “Master” member will. For example: the less advanced member will likely only need to learn about hand soldering and hotplate reflow, whereas the advanced member might want to build their own reflow oven.
