Ah. ?Robert envisions a device similar to that dingus we have
at the International Braille and Technology Center which draws
a line on paper and is no longer manufactured (only it would be
numerically-controlled). That device is, indeed, noisy but does
make a decent line.
I like the idea of the paper moving in the X-Y axis; in addition, if
we were to use a spur-wheel, the angle of the wheel with respect to, say,
the Y-axis could be variable. With Robert's suggestion of a vibrating pin,
though, there would of course be no such thing as an angle of attack.
I should think, however, that a spur-wheel would be far easier to maintain
than a vibrating pin drawing assembly.
