As a mechanical engineering student, I wanted to make something that has a mechanical aspect for my main project.
Moving light that cast shadow.
But, I didn’t consider the gear ratio which made my project spins so slow and lumen of the light bulb. If I do something differently, I would choose a totally different project because I think it would cost too much to make something that I intended to. My first intention is to light all direction of the cylinder wall and ceiling so it might need to have multiple light sources with mirrors to focus the light beam, but it would look too boxy and won’t light continuous circular light.
In the future, I would be more careful planning on something that I don’t have much knowledge of, such as illumination and electrical.
