Hi, I have just started playing with electronics, this was because my brother needed a device to do a job and I figured I could do it with a PIC and a few components and modifying an existing device, his only other option was to pay serious money to have a company do the role of the device. Great thing about this is that I'm making some nice money out of it, but I really enjoy messing about with electronics. Now I was wondering what would be the best material to study, I'm currently doing a degree in computer science and don't plan to change, but would like to know if I could get details of material that would be taught for electrical engineering. My knowledge at the moment is very basic, but I am planning to work on some rather complex projects in the future, mainly RF based stuff and data comms. Any book details or advice would be much appreciated.
