After playing with the VFD display on my PSIM I decided I did need a
display on my synth. Mounting it as a module is impractical since it
takes width and you really need to be able to see it so I mounted it
in a small portable enclosure. I power it with +5 volts and can
drive it with MIDI or 38,400 serial. Not sure how practical it is
but I thought the programming would be fun. Now I can display
various messages and speech under voltage control!
