About this app

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", "a voltage divider with a 5 V output". It understands synonyms, accents and even typos.
- Or build it by hand: add components, drag them and connect pin to pin. Pinch to zoom.
- Save the circuit to its own folder (Downloads/Jelc.Builder) with any name and open it 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 computes the components.
- Key formulas for each circuit and a printable worksheet.
- Built-in help with examples to learn how to ask.

BILINGUAL AND OFFLINE
- English and Spanish with one tap (language button).
- Works 100% offline. No accounts needed.

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