Reference Circuits Book, Volume 2: LEDs, Transistors and Oscilators

$41.50

Reference Circuits is a series of hands-on electronics learning tools disguised as books.

Instead of just reading about resistors, voltage, current, and semiconductor devices, you actually see them work through pages of fully functional DC circuits. Each circuit is designed to make core electrical concepts intuitive, visual, and immediately understandable, whether you’re learning electronics for the first time, teaching others, or using it as a bench-side reference. There is no paper in this book; it is built entirely from FR-4 printed circuit board material.

Description

Reference Circuits Volume 2: LEDs, Transistors, and Oscillators

Volume 2 focuses on the real-world behavior of active components: LEDs in practical designs, transistors as switches and amplifiers, and oscillator circuits. Every circuit is paired with clear explanations of what is happening electrically and why it works, turning abstract semiconductor theory into something tangible.

The cover features a gold-plated reference schematic, making the book itself a display-worthy piece as well as a functional learning tool.

Requires USB-C power adapter.

Page-by-Page Breakdown

Page 1 – Common Schematic Symbols
The inside of the front cover is filled with commonly used schematic symbols in gold-plated copper.

Page 2 – Light Emitting Diodes (LEDs)
How LEDs work in a circuit, LED color wavelengths, how to size current-limiting resistors, and how different LED colors correspond to different dominant wavelengths.

Page 3 – Transistor Theory
Fundamentals of transistor silicon structure in Bipolar Junction Transistors, or BJTs and Metal Oxide Field Effect Transistors, or MOSFETs.

Page 4 – Transistor Circuits 

NPN and MOSFET transistors as both switches and amplifiers.

Page 5 – Astable Multivibrator Oscilator Theory
Step-by-step explanation of how astable multivibrator oscillator circuits work.

Page 6 – Astable Multivibrator Circuit
A fully functional astable multivibrator circuit. Swap different capacitors in and out to speed up or slow down oscillation.

Page 7 – All about the 555 Timer IC
History of the 555 timer and a step-by-step breakdown of how it operates internally.

Page 8 – 555 Timer Circuit
A working 555 timer oscillator. Switch capacitors to adjust the oscillation frequency.
