I'm walking a fine line right now because if I deviate too much I'll start getting into more the physical theory rather than the applications (which is what I'm interested in). I want to go deep into circuits because I've learned all this mathematics that relates resistance, inductance, current, capacity, etc. yet I don't understand exactly what it's relating, all I can do is the mathematics.
I'm going to my friend's house today, and he's going to give me a quick breakdown of everything (he's studying to be an electrical engineer). He's got some cool devices he's going to lend me (microcontrollers, LEDs, motors, etc) so I can start tinkering as well.
