From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of Robert A LaBudde 2. Digital electronics is much easier for someone like you to get into, as the states are logic-based, and programming is an extension of logic. I don't think you would have much trouble picking up simple digital circuit analysis. >> This I had no problem with. (-: 3. Parts of electronics that involve electromagnetics (RF, radio, magnetism, etc.) are difficult to understand without special courses and considerable mathematics and experience. >> Aha! No wonder I didn't even get past the drawing board for my cell phone jammer. (-: 6. You should also obtain some test equipment (oscilloscope, multimeter, frequency generator) and do some breadboarding experiments on simple electronic circuits. A good way to start is to measurement the response to different inputs, and try to validate the device specifications. >> This I think is the key. If I can SEE what is happening from one component to another, then I think I will make a huge leap in understanding. I had just acquired a scope when I had to dismantle everything (because of moving and no place to work.) -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
