Hi, Olin > Sorry my answers sounds more like "Zen and the Art of Circuit Design", but > there is no esacping the need for being able to visualize the voltages > (pressures) and currents (flow) and how all the components react to them. > In the end there is a strong component of intuition and "lore" from > experience that I find hard to describe. My son is just 5 years old but I am saving your post just in case he ever decides he want's to learn electronics someday :-)Your description of the process was great ! Thanks... Have you ever thought about really writing something about the process of circuit design ? Using your post as a basis and refining each step might make a great tutorial for people starting at electronics design... Just a crazy thought...
