There is a book that I would like to read "Electronics for scientists" but it has physics as a prerequisite and I will not be able to take a physics course till next year (I would just take the one at my high school but the teacher is not very good and I would rather start with a calculus based approach). I am 5 chapters into "Fundamentals of Physics Halliday & Resnick", but I will have to read several hundred pages until I arrive at the electricity and magnetism section. Would it be alright if I just skipped to that section? It looks like it would be, but I would rather take your guy's advice. And I will be doing the rest next year anyways. I just need the information on circuits and components for a project I have in mind. Or if you guys know of any good resources on semiconductors, transistors, and sensors. Well the project involves using the CCD or CMOS sensors contained within cellphones. In fact if anyone just know where the is a book about has any suggestion on how the digital camera works in and out software to hardware that would be great. Thanks!!!
