Legitimate digital libraries, such as the Internet Archive (archive.org), occasionally host out-of-print electronics books for educational lending.
Download the PDF (legally, if possible), buy a breadboard, some 555 timers, and a handful of BC547 transistors. You will emerge not just as a hobbyist who assembles modules, but as an engineer who builds from the ground up. elektor electronics 304 circuits pdf

A concise explanation of how the circuit works.
Precision timing circuits using the classic 555 timer and CMOS chips.
Modern development boards often abstract the power supply regulation, signal amplification, and filtering into "black boxes." By contrast, 304 Circuits forces the builder to confront these challenges directly. A student building a discrete power supply from the book learns about ripple rejection and heat dissipation in a way that using a pre-built USB module cannot teach. Furthermore, the schematic diagrams in the PDF are high-resolution and clearly drawn, adhering to a standard of graphical clarity that facilitates easy reading and reverse engineering—a quality often lacking in crowded, auto-routed modern PCB layouts.
