I now found many projects how to make a simple projector using a light and magnifying glass. You can use the image of a phone or tablet too but that is very dim. I think the option to print or draw on transparency and then project it with a light source will be the simplest of you don't have a data projector.
This is a great project that I would like to pursue. What would the next steps be to make it possible to trace the lines of an SVG file? I want to trace the outline of something like this http://theultralinx.com/2015/07/20-awesome-optical-illusions-typography/ with the laser from a certain position and then mark the trace on the walls to paint (fill in) after I am done. The laser don't need to move fast (just as fast as I can follow) but it would need to be quite smooth for curved lines. How would one do that?
Laser Painting With Motion Control and Arduino
This is really awesome and I love the whole projector topic and now also had to go find your country on a map (I am from South Africa and before Nelson Mandela, also no one new where "South" "Africa" was :-)
I want to do this too but I assume you have to spend a lot of time moving your tape around while monitoring the end result on the phone. For a quicker and more precise way, when a projector is not at hand or not practical, isn't there some cool way to build a quick moving pen laser which "paints" the outlines for you to paint on? It would offcourse be much more work than using a projector but it allows for much greater distances to be covered (where a projector light will be too dim).

I am worried about the life expectancy of the panel since I've seen that those sign boards don't last long outside in the sun (it is afterall made as cheap and light as possible and not made to last). Wouldn't the inner bits of plastic break down quickly as well? I suppose the paint coating should help that the UV don't break it down, from outside at least. I have a can of heat resistant black paint in the garage left and was wondering if that would be even better than normal paint?
