Each circuit depicts an original, traced and hand-drawn schematic created by Forrest Mims for his iconic books Getting Started in Electronics, and the Engineers’ Notebook series. Every board includes a description of how it works, in Mims’ handwriting, on the reverse side.
Alongside the schematic is the circuit itself. Paired with the components you need to build up timeless examples such as the Dual-LED Flasher, the Stepped Tone Generator, and the Bargraph Voltage Indicator, each board is carefully designed for easy assembly recreating the wonder of learning how electronics work— whether it’s your first soldering project or your fifty-thousandth.

There are a lot of high-tech drones and RC planes flooding the market lately, and the innovations are coming so fast on each new iteration, most of them forget one crucial thing: Flying these is supposed to be fun. Here’s an alternative that keeps that ethic firmly in mind: The Moskito Smartphone-Controlled Plane. This thing […]
There are few intellectual exercises better than a good game of chess against a capable opponent, which is why a lot of old hands at the gameplay it online. But there’s still nothing like the tactile thrill of moving a knight into checkmate. (Or sweeping the pieces off dramatically when you lose.) That’s why we’re […]
