Approximately 60-70 circuits fall into this category. You will find:

If you are an absolute beginner, start with Getting Started in Electronics by Forrest Mims. But if you have a breadboard, a soldering iron, and a desire to build something that isn't connected to the cloud—find the Elektor 305 Circuits book. elektor 305 circuits

You might think: Why bother with 30-year-old circuits when we have microcontrollers?

Here is the argument for keeping the Elektor 305 in your digital library:
