Written by an engineer who was tired of watching students memorize formulas without knowing what silicon actually does.
This site started as a promise: a free, no-login reference platform for students learning the physical layer beneath all the software they use every day. No sign-up walls. No tracking. Nothing hidden behind a subscription.
Ten calculators, six glossary entries, one clear mission — help students think in circuits, not just formulas. Every calculator lets you share your work as a URL and save your recent calculations locally. All in your browser, nothing sent anywhere.
The larger platform will let you upload a schematic, get a plain-English walkthrough of what each component does, and simulate simple circuits interactively. Trained on decades of EE textbooks and datasheets. Beta opens soon. Subscribe on the homepage for early access.
Because fundamentals don't have a price tag. Ohm's Law works the same way everywhere, and every student deserves the same quality reference; regardless of where they study, what they can afford, or which university's name is on their certificate. Knowledge for all.
