Electronics Vocational School - Introduction

Electronics Vocational School is a complete series of courses, using which you can gain all the theoretical and practical knowledge to work as an electronics technician in different fields related to electonics.

It is important to note that these courses will not substitute an electronics engineering course, as advanced topics in electronics like analog and digital signal processing will not be discussed here.

In these courses, you will learn just about enough of everything to be able to work as an electronics technician. Therefore, you will not study advanced subjects like physics of semiconductors. You will study enough mathematics, physics and chemistry to help you understand the material that is presented in electronics related books in this course.

It is also important to note that all the necessary concepts will be discussed in the courses included here. For example, every electronics technician needs to know how to design and draw parts on a computer, order them and have them built or 3D printed. Therefore, we have a complete course on computer drawing that will be presented as a part of these courses.

The courses presented here are designed to be taken in six semesters or in three years' time but it is up to you how fast you would like to go through the courses. You can take as much time as you need to complete the course.

Below, we have broken down all the necessary subjects to three levels. You can think of each level as representing one year or two semesters. It is necessary to finish all the subjects related to each level before moving on to the next level.

What is missing from these courses right now is a couple of courses on computer programming. Over time, we will plan the necessary courses and add them wherever they are required.

Creating this learning track is work in progress. It is going to take us a while to create all the courses related to all the three years. While creating the courses, other useful material might (and most probably will) be added to the learning track. For example, every electronics technician, needs to know some basics about computer hardware, computer networks and some useful operating systems like Linux. Those subjects will be added to the learning track as we go along. The following is just a rough blueprint of the learning track to help us get started and going.

As a final note, the learning track presented below can be used to learn other vocations as well. As an example, once you have learned the material below which is primarily related to electronics, there is not much that you need to learn to apply your existing knowledge to electrotechnic or other related fields like power generation and transmission, etc. All such vocations have many modules in common. For example, mathematics, physics, chemistry, basics of computers, computer programming, computer drawing, environment, business, etc. are all common to all such fields.

As the prerequisite for this learning track, you don't need much but the following:

What is meant by "class 9" above is, in most educational systems, there is a level up to which students study mainly sceince, language and mathematics. Once this level is completed, students will start studying standards physics and chemistry. The level mentioned above, we have called "class 9", irrespective of what it is called in the educational system you happened to attend school in.

Course Reference Book

The Course Reference Book brings together all the important material from throughout the entire course (all the three years). In this book, the material will not be as detailed as where it was originally discussed in the course. Usually, the material is recorded in compact form so that you can come back to the material whenever you need to use it later. This is usually formulas from mathematics, formulas from Electronics, etc. In short, the Course Reference Book is a collection of all the useful material that you need while doing something that you might forget.
