Eventually, you will have to perform the analysis yourself, simply because nobody else has published it for you to study it. This will require some familiarity with fundamentals, such as circuit theory and analysis, transistor circuits and opamps. Razavi's book "Fundamentals of microelectronics" is a classic textbook for ECE courses worldwide, and you can find the video lectures here <a href="https://www.youtube.com/playlist?list=PL7qUW0KPfsIIOPOKL84wK_Qj9N7gvJX6v" target="_blank">https://www.youtube.com/playlist?list=PL7qUW0KPfsIIOPOKL84wK_Qj9N7gvJX6v</a> . Its purpose is to prepare students for more cutting edge electronics that follow on later courses, so perhaps it is way deeper than you want at times, but it is one of the best resources to give you an intuitive understanding of how semiconductors work and how a design or analysis problem can be approached. </div><div><br></div><div>While many things can be skipped ahead, learning the fundamentals of circuit theory in a structured manner (and also solving some exercises on your own, with a pencil and paper) is essential. What is voltage and current, Kirchoff's laws, nodal and loop analysis, Thevenin and Norton's equivalent circuits, how to handle dependent sources are the main prerequisites for anyone wishing to analyse electronics later on. Regular ECE courses on circuits are very big and boring if you just want to get on with it, so I am reluctant to offer any specific suggestions from resources I've learned off or use to teach students now. From my experience, most textbooks' approach is very similar, so just use one that you feel comfortable reading.</div><div><br></div><div>Complete instruments are rather big projects and might seem overwhelming. You can find various smaller, simpler devices to assemble and learn along the way, for example, the atari punk console, or various overdrive/distortion circuits from the guitar world. </div><div>While not absolutely essential, an oscilloscope will be very handy in your journey. There are various options nowadays - ideally, you'll bite the bullet and spend 300-400$ on a low-end benchtop scope, but if that's beyond your reach, there are cheaper options, such as USB scopes or even the DSO nano, which compares poorly to the other options but can be had for under 100$ and will suffice for your first few steps in this hobby.</div><div><span style="text-align:center">As far as soldering tools go, a semi-professional model like the Hakko fx-888 would last you a lifetime and offer a nice experience, but if the budget is tight you can go for any cheap option and upgrade later. I used a generic 15$ iron for more than 4 years, and have soldered everything with it, including tiny SMD parts.</span></div><div><span style="text-align:center">No matter the course of action you decide to follow, try to stick with it, and when things get hard, take a break and get back at them harder. While this list will always chime in to help you with any questions, you may find it convenient to join some relevant Facebook groups as well, if that's your thing.</span></div><div><span style="text-align:center">Regards,</span></div><div><span style="text-align:center">Spiros</span></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Oct 9, 2020 at 2:56 AM J P <<a href="mailto:griffzero0000@gmail.com" target="_blank">griffzero0000@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hello, <div><br></div><div>I've been wanting to get into building synths and electronic instruments for years, but never knew where to start.
