The other day I needed to build a circuit to bump 3v up to something between 3.5 and 5 for my CHDK Remote Cable hack. I looked up a handful of schematics for circuits that do this… and realized I didn’t really understand what any of them were doing. At least not well enough to appropriate the circuit for my own needs.
I took Electricity and Magnetism second semester of my senior year of high school. Which is to say I don’t remember any of it. So I figured it was time I actually learn the math behind the electrical circuits I’m building instead of sticking things together haphazardly to see if they work. I remember how to use V=IR, but that doesn’t really answer the question “how do I bump 3v up to 3.5v?”
I’m reading “Teach Yourself Electricity and Electronics” , so far I’m just as far as some basic concepts of DC and AC power. Of course I almost never do anything with AC power, but I suppose it’s handy to know.
The book itself is pretty dry. But it’s an electronics book, so I suppose any of them are going to be dry. If there are any other good basic electronics theory I’d love to hear them. On the plus side, this one is great for getting me to sleep.
