Jelc.Builder

Jelc.Builder is an electronic circuit generator designed as a companion to the Jelc.Simulator: build the circuit here and open it there to see it work.

HOW IT WORKS
-Type it in words: "a common-emitter amplifier", "a low-pass filter cutting at 1 kHz", or "a voltage divider with a 5 V output".
It understands synonyms, accents, and even typos.

-Manual mode: Build it by hand using your finger. Place parts, drag them, snap them together, and wire them pin-to-pin. Pinch to zoom and undo whenever you want.

-Save & Export: Save the circuit to its own folder (Downloads/Jelc.Builder) with any name and open it instantly in the simulator.

WHAT'S INCLUDED
94 ready-made circuits: Resistive, RC/RL/RLC, passive filters, diodes and rectification, power supplies and regulators, BJT and MOSFET transistors, operational amplifiers, 555 timers, oscillators, digital logic, and power.

-Goal-based design: Ask for "gain 20" or "cut at 1 kHz" and it automatically computes the component values.

-Educational resources: Get a clear explanation, the key formula, and a printable worksheet for each circuit—ready to hand out to a class.
Built-in help: Includes practical examples to learn exactly how to ask for circuits.

GLOBAL & ACCESSIBLE
-100% Offline: No internet connection or accounts required.10 Languages: English, Spanish, Portuguese, German, French, Italian, Polish, Russian, Turkish, and Hindi.

-Ideal for electronics students and teachers who want to go from idea to circuit in seconds.
