I have the "Mpow Projection Alarm Clock" (https://amzn.to/2VtA1Cx) and although in the example image the time projected on the ceiling is gigantic, in reality it's only about 7 inches (18cm). It's still small when I project it on the other side of the room (I have a small room). I want it to be much bigger.. Ideally triple the size.
I tried holding two kinds of magnifying glasses at various distances over the thing where the time is projected out and that doesn't work. The projected time turned into an unreadable circle. I tried a camera lens and perhaps the projection isn't bright enough because nothing was visible - no light was coming through.
