Excuse my ignorance. I know nothing about lasers. However, I want a projector that will put simple shapes on a wall. I would like to program this in the most basic form that I can. I'll use a square as an example. I'd like to input onto a spreadsheet or csv the 4 points 0,0 10,0 10,10 0,10.
Where do I find a laser kit so that I can do this?
