Jelc.Builder

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.
