Hand-illustrated electronics that shaped a generation
Basic Semiconductor Circuits
Fundamental transistor and diode circuits with Mims' signature hand-drawn illustrations. Covers NPN/PNP transistors, rectifiers, voltage regulators, and basic amplifier configurations.
Engineer's Notebook II
The foundational handbook covering integrated circuit applications. Features Mims' iconic hand-drawn schematics for op-amps, timers, audio circuits, power supplies, and dozens of practical IC projects.
Op Amp IC Circuits
Comprehensive guide to operational amplifier circuits. Covers inverting/non-inverting amplifiers, comparators, integrators, differentiators, and practical applications.
555 Timer Circuits
Everything about the legendary 555 timer IC. Monostable and astable modes, pulse generators, oscillators, and creative timing applications.
Preserving Electronics Heritage
These references represent the golden age of hands-on electronics education. Forrest M. Mims III, a Texas A&M graduate and one of the most widely read electronics authors in history, taught millions through his hand-drawn Radio Shack notebooks. His work sits alongside Ugly's practical field guides, trusted by electricians everywhere.
What makes these works special is their approach: clear explanations, practical focus, and a personal touch that made complex concepts accessible. Many engineers credit these materials with sparking their interest in electronics — reading them under the covers with a flashlight, building circuits on breadboards, learning schematic symbols for the first time.
