Tool/software:
Hi, I am a design student making a product that needs a small and functional projector like this one. However, I can't understand, where the touchpoints are to control focus, orientation, and projection distance. I am now designing a wall lamp for kids to enhance bedtime stories and I wished to use a projector that could project images on the ceiling of a kid's bedroom, however, I don't understand where I could connect rotary switches or so, to adjust angulation, focus, and image dimension. Furthermore, I don't know If I should take into account adding a small ventilation fan in the product to dissipate the heat from this projector.
