Lemur heliostat

In winter there is no sun in our garden. Once in a while the sun is reflected into the garden by a neighbors window. This lasts just for a couple of minutes but I always enjoy this moments of sun. This made me think; what if I put a mirror on my neighbors roof which adjusts to the sun’s position so that it reflects sun into my garden all day long?

During Fab Academy I created such a mirror as a final project.

The heliostat I’ve built isn’t ready to put on the neighbors roof but it’s a fully working small scale prototype. In future I plan to build a version than is bigger and weather proof that can be mounted on a roof.

Do you want to know the details of this build? Check out my final project documentation.
