Many of us have no formal background when accepting new hacking attacks, and we have to teach ourselves complex concepts and learn in practice (or more commonly, through failure). To help new hackers get started more easily, [PhilosopherFar3847] Created a fantastic e-introduction resource, Summary of the electronic agenda for electronics.
[PhilosipherFar3847] The purpose of creating Electroagenda is to help hobbyists, students and professionals to better understand electronic products. The electronic abstract is one of the most recent additions to the site. It is divided into 26 sections, each of which breaks down different electrical concepts into easy-to-understand facts, without math or unfamiliar terms. The summary covers a wide range of electronic products, from simple passive components and their uses to the basic operating concepts of microcontrollers.
Although this resource by itself is not enough for a fledgling hacker to start making cool circuits, it does provide a very important skill; knowing how to ask the right questions. This knowledge base provides enough context and keywords to better express challenges and express Google-fu more effectively.
You are the fledgling hacker mentioned earlier, do you want to learn more? Look at these beautiful logic gates, you can plug in each other to build a basic circuit.
