"This article show how to use the BLC2021 PC-Bay Insert serial line display from Matrix Orbital under Linux. The BLC2021 is a small dot matrix LCD display which is very easy to use and does not require any additional controller chip or complicated driver."

"With some hobby building skills you can use you can use your old PC to build an MP3 player for your living room or to control the central heating in the house or just use it as an intranet server. The use cases are probably manifold. In all of these cases it would be nice to have the computer inside a small metal box without a big monitor and keyboard around. Instead you would like to have a small LCD display which shows the title of the current song on the MP3 player, the temperature for your heating control system or the status of your server."

"LCDs and computer electronic in general are rather sensitive things. Connecting an LCD display backward to power supplies or to too high voltage can easily destroy the display. We present in this article the BLC2021 serial line PC bay insert because it is very easy to install and comes with all the cables needed to plug it into your computer. All you need to install the BLC2021 is a small screw driver. With the ready made cables and connectors that come with the BLC2021 there is not much that can go wrong."
