By the way, one method for eliminating the LCD is to use "canned speech" audio as a user interface. For much less cost than an LCD, the system could play pre-recorded phrases stored in flash memory to a cheap amp+audio speaker, i.e. "two minutes. starting now." Or "two minutes. spinning down. complete." Many chips have more than enough CPU power for this now. It's funny to see lab equipment with these huge colorful displays (adding significant cost) when all they really need is a way to indicate a single measurement number or show the user what operational mode the equipment is currently running in.
