I am interested in enrolling in one of the course levels in CE but am undecided as to where I want to start. I am above a beginner level and have made my own projects/ board layouts etc. from a hardware standpoint. I have worked quite a bit with the Arduino platform ans made a few projects with the SMD version of the 328P and dipped my toe into the PIC world as well with a few simple programs in the MX8. I am interested in analog front end design, power supply design both linear and switching and battery powered products, but also interested in furthering my firmware/software side. I am on the fence as to either the Journeyman course or the Apprentice course with the AD2 package. Is there anyone in those levels that has any input on their material or the learning experience?
