2 Transistor / MOSFET tutorial
A beginner tutorial on using BJTs and MOSFETs as switches, often suggested when a microcontroller pin needs to drive a motor, laser or other larger load.
3 Making logic gates from transistors
Ben Eater builds basic logic gates from transistors, resistors and LEDs on a breadboard; beginners often follow it, then ask how the XOR circuit works.
4 MOSFETs and How to Use Them | AddOhms #11
Short explainer on how MOSFETs work and how to switch loads with them; offered to people moving from a small BJT to a MOSFET for motors.
5 Tutorial 05 for Arduino: Motors and Transistors
Part of Jeremy Blum's Arduino series, driving a DC motor through a transistor; followed by beginners, who often then ask about base resistors and battery choice.
6 #190: Back to Basics: Transistor Current Sources and Mirrors
Alan Wolke explains discrete transistor current sources and mirrors, ending with LED driving and compliance voltage; suggested as an alternative to an LM317 current source.
7 #193: Back to Basics: the differential amplifier, aka long-tailed pair, diff-pair
Alan Wolke gives a gentle introduction to the BJT differential pair and how it forms an op amp input stage; people build and simulate along with it.
8 Homebrew NMOS Transistor Step by Step - So Easy Even Jeri Can Do It
Jeri Ellsworth makes an NMOS transistor at home step by step, the usual link when someone asks whether a transistor can be made by hand.
9 #198: Basics of a Vbe Multiplier: what it is, how it works & where it is used
Explains the Vbe multiplier, or rubber diode, and how it sets bias in class B output stages; the usual link when someone uses plain diodes instead.
10 #105: More Circuit Fun: Simple 3 transistor sawtooth generator / oscillator
Builds a simple three-transistor sawtooth oscillator and shows it running on a scope; people copy the circuit but report it gets finicky at higher frequencies.
11 Soft touch power switch (Push on Hold off)
Explains a push-on, hold-off soft power switch built from transistors with a readable schematic; recommended for battery projects that want one button for power and input.
12 What is a transistor? How does a transistor work? Part 1
Explains how to use a transistor in practice, as a resistor controlled by the base rather than through semiconductor physics; liked by learners put off by textbooks.
13 Controlling a DC Motor with the Raspberry Pi
A beginner tutorial on driving a small DC motor from Raspberry Pi GPIO with a transistor and PWM, suggested as a basics starting point.
14 How TRANSISTORS do MATH
Explains how transistors form logic gates and how those gates add binary numbers, linked when people ask how a computer physically does arithmetic.
