>> use a dsPic to generate TV signals for a plasma display? >> That might be a bit too big. But writing via serial to a regular PC with LCD or CRT display might be a reasonable idea. Someone ought to write a "virtual serial LCD" program for a PC, complete with pictures that look just like the real thing. That would give you a LOT of flexibility as to display size and visibility for demos...
