What Our Users Say
"This is the most beautiful app I've ever used. Everything works — the loud bell, the buzzer buzzing, the fan spinning. Love this app."
"We were able to hit the ground running as soon as we started using it. Everything is straightforward and easy to understand. For anybody wishing to use a circuit analysis package, I wouldn't recommend anything other than DCACLab."
"The breadboard feature looks fantastic — it will be a valuable tool for teaching prototyping and circuit design."
Our Journey
About the Founder
Samir Sabri
Founder & Product Engineer
I'm a computer science graduate with a career spanning IT and educational software development. I built DCACLab because I believe the best way to learn electronics is by doing — building circuits, testing ideas, and seeing results in real time.
When I launched DCACLab in 2009, there were very few online circuit simulators available. The goal was simple: make electronics education accessible to anyone with a browser. That goal hasn't changed.
I'm always happy to hear from educators, students, and institutions. If you have suggestions, feedback, or questions, don't hesitate to reach out.
Our Roots
Said Sabri at his workshop, 1966
DCACLab's story started long before the first line of code. My father, Said Sabri, was a professional electrician. Growing up, I built simple lamp circuits at his workbench — and that hands-on experience shaped everything DCACLab would become.
The platform carries that same workshop philosophy: learn by doing, test your ideas, and see the results for yourself.
