If it wasn’t obvious, I’m also an electronics geek

I’m also a bit of an electronics geek besides being a computer software engineer too.

It’s why I’m always thinking of ways to apply certain technologies to every day problems.

So I found this very interesting open source set of books on various topics in electricity and electronics called “Lessons in Electric Circuits”

I’m reading the book on direct current or DC right now. I’m 25 pages into a 560 page document and so far we’ve covered static electricity, basic nuclear physics, voltage, current, voltage drop, and resistance. I cannot wait to read the other 535 pages!

What is more fascinating about these books is this:

This book is published under the terms and conditions of the Design Science License. These
terms and conditions allow for free copying, distribution, and/or modification of this document
by the general public.
The full Design Science License text is included in the last chapter.
As an open and collaboratively developed text, this book is distributed in the hope that
it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of
License for more details.
Available in its entirety as part of the Open Book Project collection at:

The bold section says it all. “These
terms and conditions allow for free copying, distribution, and/or modification of this document by the general public”

There are a series of SIX books in the series covering AC Circuits, Semiconductors, Digital Circuits, Reference material, and a lab or experiments manual. I have to say, pretty comprehensive stuff. And the book covers are interesting too. For example the straight road for DC, the curving road for AC, and the partially blocked road for semiconductors, and the multi-path for logic circuits.

I’m happy to see publications like the ones above. It encourages people to both learn and to actively contribute. This is where copyright falls flat on its face.

And think about it, electronics is simply the method of using the flow of current to do work of some sort. Whether it’s to light up an LED, or scroll information across an LCD screen, it’s all based on the principles of controlling current.

And I like how the books are organized. The two volumes for DC and AC will give you enough basic knowledge to start building oscillators, then radio receivers and who knows, radio transmitters. Or if you’re so inclined in the 5V world, you can used the Digital guide to understand Boolean logic and how to implement those via electronic circuits.

Enough geeking out for now. But check it out if you’re even remotely interested in how electronics gear works.

  1. I can replace a cord on a lamp or replace a thermostat. Other than that, electricity scares me. The license is similar to Creative Commons. Basically protecting the copyright (insofar as that is possible) while recognizing that anything on the internet is subject to being used by anyone. An evolving concept.
