Open Circuits is a photographic exploration of the beautiful design inside everyday electronics. Its stunning cross-section photography unlocks a hidden world full of elegance, subtle complexity, and wonder.

Our phones, computers, and appliances are made of hundreds of internal components, each precisely engineered to perform a certain function, but none intended to actually be seen. Through painstakingly executed, vividly detailed cross-section photography, Open Circuits reveals the surprising—and often accidental—beauty hiding inside the electronic components that drive our everyday devices. 

From resistors to LEDs, USB cables to headphone jacks, stepper motors to nixie tubes, the book’s arresting imagery transforms more than 130 components into delightful works of art. As you visually dissect the components’ insides, you’ll learn about how they work and how they were made. Open Circuits has something for everyone to appreciate, whether you’re a seasoned electrical engineer, an amateur tinkerer, or simply a lover of art and photography.

Eric Schlaepfer runs the popular engineering Twitter account @TubeTimeUS, where he posts cross section photos, discusses retrocomputing and reverse engineering, and investigates engineering accidents. Some of his better-known projects include the MOnSter 6502 (the world’s largest 6502 microprocessor, made out of individual transistors) and the Snark Barker (a retro recreation of the famous Sound Blaster sound card).

Windell H. Oskay is the co-founder of Evil Mad Scientist Laboratories, where he designs robots. A longtime photographer, he holds a B.A. in Physics and Mathematics from Lake Forest College and a Ph.D. in Physics from the University of Texas at Austin. He is the author of The Annotated Build-It-Yourself Science Laboratory.
