Quite the
contrary, I enjoy designing and constructing digital
electronics. I consider it a pleasant use of my time.
I'm going to need an
X/Y driver myself here pretty soon.
I ocne used a soundcard output as an X/Y display driver - stereo
output, with X in one channel and Y in the other.
It worked, but not well; the output turned out to be capacitor-coupled
(as in, the long-term DC value is always zero) and is filtered,
presumably in ways that make sense for audio signals. Still, I managed
to get it to display some simple vector graphics.
One of my "when I win the lottery" projects is to build something
better for that. Not because I have a use for it, but because I think
it'll be fun to build (or try to build, as the case may be). I also
want to take a 3RP1 I have and build an oscilloscope around it, a
related but distinctly different project....
