I almost made a laser projector last year, but I was
having problems
sourcing mirror material at the South Pole. One thought was gutting a
laser printer or a copier (ISTR there's a front-surface mirror in
there somewhere that's as wide as the paper path), but there was
nothing suitable scrapped while I was down there. Now that I'm home,
I'm keeping an eye out for a cheap/free printer to scavenge. I
already have the semiconductor laser, naturally - the grocery store
was selling laser levels for less than the cost of lunch.
Ethan, in a laser printer there is an hexagonal (or n-sides, don't
remember) mirror that you can easily use to scan a horizontal section
