I personally find it ridiculaor that people are
suggesting that
something like a paper tape reader, for which the mechanical parts
could be made in any model engineer's workshop and the electronics is
a handful of parts should be emulated by a scanner (many moe
photodetectors than necessary and a powerful processor to prewcess
the images from said scanner. Please stop trhwing silicon ant the
problem!
If the person in question doesn't already have either one, I agree.
But if you already have a scanner, known to work, and don't have the
parts you mention, or don't have the "model engineer's workshop"
tools...then I have trouble seeing anything wrong with using the
scanner.
That would, for example, be my own case - I probably could kludge
something together to pull paper tape past phototransistors, but (a) it
would be a kludge, (b) I don't have the phototransistors, and (c) I
don't have (I would have to design and build - not difficult, but it
would have to be done) the electronics to interface the thing to a
computer. I do, however, have a scanner that needs nothing more than
plugging in of wires to work fine.
