Circuitry (Electronics) Help/Books Answered
I am looking to expand my electronics knowledge. I already know the basics (and a bit more), so please no suggestions for the basics. I know enough to build my own basic custom circuits. I am very knowledgeable about the Arduino (I use it practically every-day). I know how to use resistors, capacitors, transistors, most diodes (LED, Photo-resistor, current-blocking, one way, zener, etc.), and much more. I am self-taught, but want to further my education.
I am VERY interested in robotics (I plan to work in aerospace engineering when I'm older), if that helps any. I am in need of good books to read on. I've gone through most of the projects in Forrest M Mim's books that I got in a kit from radioshack. I really would prefer some eBooks, though. Free is good, but I'll pay if it is necessary. Thanks!
