About this app

Jelc.Builder turns what you type into an electronic circuit. It is the companion of Jelc.Simulator: build the circuit here, open it there and watch it run.

HOW IT WORKS
• Say it in words, in your own language: "a common emitter amplifier", "a low pass filter cutting at 1 kHz", "a divider giving 5 V at the output", "a 30 second timer". It understands synonyms, accents and typos.
• Or build it by hand: pick parts from a palette of 87, drag them and wire them pin to pin. Pinch to zoom.
• Save it under any name you like (Downloads/Jelc.Builder) and open it in the simulator.

WHAT YOU GET
• 129 ready circuits: resistive, RC/RL/RLC, passive filters, diodes and rectification, power supplies and regulators, BJT and MOSFET transistors, op amps, 555 timers, signal generators, oscillators, digital logic, flip-flops, counters and registers, multiplexers, decoders and adders, sensors (LDR and NTC) and power.
• Design by goal: ask for "gain 20", "cut at 1 kHz" or "5 V at the output" and it works out the component values for you.
• Values you can actually buy: it picks the pair from the E24 commercial series and tells you what it really gives, instead of a 1591.55 Ω that no shop sells.
• The formulas behind each circuit, a printable worksheet and a shopping list.
• Built in help with examples, so you learn how to ask.
• A data sheet for every part and every circuit: the symbol with each pin named, and for all 129 models the drawing, how it works, what to measure and what to check if it fails.

For students, teachers and electronics hobbyists who want to go from the idea to the circuit in seconds.

What’s new

Two new windows in Settings:

• Parts: a data sheet for each of the 87 parts, with the symbol shown large, the name of every pin and what it is for.
• Models: a data sheet for the 129 circuits, with the drawing, how it works, what to measure and what to check if it fails. Plus a button to build it.

The palette grows from 76 to 87 parts.

And 14 circuits that did not do what their name promised were fixed.

And the app now tells you when a new version is on Google Play.
