i like your idea of the projector. i made i slightly differently but with the same principle. but anyway i was just asking do you think if i get the right sizeed mirror the same principle would work for a laptop or portable dvd player?
It should work just fine, but it might be somewhat darker at the edges due to the fact that the touch has a lager screen. Give it a go and let us know how it works!
That's only for new ones. Sometimes people create an entirely new Instructable for major updates and link back to the old one. I would not recommend deleting an old one because there are probably a bunch people linking to it.
