Open-source CLI tool
A local command-line tool built for engineers and makers. Feed it any electronics file — firmware, schematics, datasheets, PCB exports — and get an instant structured report. No cloud, no account, no data leaving your machine.
Electronics · Explained clearly
Clear explanations, interactive diagrams, and real-world examples — for curious beginners and engineers who want to go deeper.
Six tracks covering electronics from Ohm's law to embedded systems — go at your own pace.
One resistor, one capacitor — and suddenly you can separate low frequencies from high ones. The RC filter is one of the simplest circuits in electronics, and one of the most revealing. We break down its time-domain behavior, its frequency response, and where you'll actually use it.
Read the articleA simple mental model to understand how a transistor amplifies or switches a signal — no intimidating equations required.
Bandwidth limits, rise time, and Fourier series — what your oscilloscope is actually telling you about your signal.
How a switch, an inductor, and a diode collaborate to step down voltage with far less heat than a linear regulator.
Stated by Georg Ohm in 1827, this linear relationship underlies almost every circuit analysis you'll ever do. Understand why →
Interactive utilities to experiment without hardware — and sanity-check your calculations on the fly.
Every Sunday: one diagram, one explanation, one formula. No noise.
