Free 3D simulators for Technology classes
I’m Jaime, a Technology teacher in a secondary school in Spain. I built these interactive 3D simulators for my own classes, and they are free for anyone: open one in your browser, change the values and see how a mechanism, a circuit or an engine really works. Nothing to install and no sign-up.
Each simulator shows the formulas and the numbers behind what you see, so students can check their own calculations. More simulators, full teaching units and articles are available in Spanish, and I am translating the most useful ones.

Why I made them
Mechanisms, electricity and engines make sense when you can see them move. I could not find simulators that let my students change the data and check the results, so I made my own, with the help of AI for the programming. The teaching design and every formula are mine, and I test them in class with my students. More about me →
