While I was playing with colour Nokia LCDs other people were playing with older displays. Roll on the 3310 crowd. This LCD is more suited to smaller projects, its only 84×48 resolution, has no built in backlight and is black and white only.
This means it takes a lot less power to both run it, and display things on it. This guy has taken a 1wire temp probe and 8pin pic to make a very nice standalone temperature monitor with the Nokia LCD.
