About Me

Hi!, This is Samir Sabri, the founder of DCACLab, thanks for your visit.

I've been in the field of educational applications development for over 18 years, holding a bachelor's degree with a major in computer science, I just love to develop simulators and I love computer programming. My father was a professional electrician, I started creating little lamp based circuits at my early years of childhood by the help of my father, from there the journey has begun!

DCACLab is intended to be a place to simulate and study circuits online, using a user friendly interface. If you are a teacher then you will find the virtual lab very useful as it will help you teach your students by using interactivity and real time results, as if they were playing a game! And if you are a student, then you will be able to learn and experiment with circuit while making it via various components and measurement tools.

Hobbyists can test and build a circuit that would take an hour at the real lab, can be done in 5 minutes using the virtual lab, DCACLab was launched at 2009, it was within the first online virtual labs out there.

I am happy to listen to your suggestions, ideas and recommendations.


Happy simulation!🙂
