This is lovely and also a great micro:bit resource. The folks over at Kitronik have written a detailed explanation of how to build this great London Eye and turbine station model over on their blog. It uses their All-in-One Robotics Board to drive both the “Eye” and the wind turbine on top of the turbine station. They include all the files to help you laser-cut the models (although I daresay you could do the same out of cardboard manually) and extensive instructions on how it goes together. This was part of their Bett 2019 display and you can read all the details and see the information about their “City” display here.
