 For one thing, why not build a reader? Ought to be a
fun weekend
project ;) The other question is whether the Scantron units use
optics or electric sensors for checking multiple choice tests. I'm not sure
about this, but electronic makes a LOT more sense.  That's why
whenevery ou fill in one of those bubble sheets, they make sure that you use
a "Number 2 pencil." Because it has carbon in it.  With an optical solution,
anything from crayon to pen to marker should work, if it were black.
    Just my 0.02...
