It's such a wide topic. I keep coming back to it, though I only tinker. I've recently gotten into modular synths, and that's neat becasue there are plenty of kits to build wihtout having to know a lot about hot the stuff works. In the last month I've built a pretty complicated VCO and an Oscilloscope. The stuff is cheap. I've had a pretty good informal education as a nerdy musician and computer guy over the last 2 decades. IMO the good thing is to keep in mind that a) for low voltage stuff you can mess around a lot and not hurt yourself (the devices can be another matter) and b) a lot of this stuff is just within 10% tolerance... like you can do a lot with minimal knowledge. I got a lot out of a series of youtube videos that were tied to a company selling kits of resistors, breadboards, etc: http://www.pyroelectro.com/edu/ http://www.pyroelectro.com/edu/ And then it's like learning to code (if you know how to do that): find a project that seems like you more or less understand the broad strokes and try to implement it.
