Fahed Lab — the English gateway
A free education site for electricity, electronics and physics: dozens of interactive simulators and virtual labs that run right in the browser, full courses, and exam solutions. The interface is trilingual — Hebrew, Arabic and English.
🔨 Build-it-yourself labs
Smart circuit builder
Drag components onto a workbench, wire them freely and measure — with an AI circuit generator built in.
Open →Panel and control lab
Build an electrical panel on a DIN rail: breakers, RCD, contactors, a VFD, a PLC and an Arduino — then power it up and troubleshoot.
Open →Transistor exercise generator
Build BJT amplifier stages on a board: DC operating point, load line, small-signal gain and clipping, with a scope.
Open →Op-amp exercise generator
Chain op-amp stages, watch voltages and waveforms at every stage, and generate practice questions with solutions.
Open →Arduino block programming
Drag commands, see real code, and run it on a virtual board with a relay, a motor and a servo — ten guided tasks.
Open →ESP32 block programming
The same block editor on an ESP32: a 12-bit ADC, PWM dimming, and pins that are inputs and outputs — ten tasks.
Open →🎓 Full study tracks
Electrical engineering, control and energy
The complete curriculum from basic circuits to motors, PLC and the final project — a simulator for every topic.
Enter →Electronics and computers
Analog and digital electronics, programming and microcontrollers — every chapter with its matching labs.
Enter →Physics portal
Advanced high-school physics — mechanics, electromagnetism, radiation and matter — with a simulator for every topic.
Enter →📚 More on the site
Digital textbooks
Complete interactive textbooks with live labs inside the chapters — published in Hebrew and Arabic editions.
To the library →National exam solutions
Israeli bagrut exams in electricity and electronics, 2016–2026, each with a full step-by-step solution (Hebrew and Arabic).
Enter →Arduino code lab
Write real code in the browser and run it on a virtual board — LEDs, buttons, a potentiometer, a servo and a speaker.
Open →Inside View: 3D Models
Machines and components you can take apart and run: generator, induction motor, servo motors, distribution transformer, wind turbine, pumped storage, solar panel, contactor, thermal relay, relay and breakers.
