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:

The bold section says it all. “These

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.
