Understand circuits. Build things that work.
Articles and courses that explain the reasoning behind a circuit, not just the steps to copy one. Start from a breadboard and Ohm's law — go as far as you like.

A complete ground-up course — from binary arithmetic and Boolean algebra through RTL design, testbenches, advanced Verilog, and five capstone projects.
Build first, theory after
Every guide starts with a working circuit. The theory shows up once you've already seen it do something — that's when it sticks.
Real components, real mistakes
We show the burnt resistor and the reversed LED, not just the finished board. The mistakes are half the lesson.
No prior math required
Ohm's law is three letters and a triangle. We introduce formulas only when a circuit in front of you needs one.
