Build an LCD Display for your Computer

(page under construction)

A recent project for our Main_Page K-LUG Linux User group was to create ourselves LCD Displays for computers. We created kits containing all necessary parts for < $20. Some used their LCD Display to show the health of their headless servers, some to show off title and artist information from an MP3 player, and others still to simply have fun with animation. Here is a picture of one of the finished products

Intro to the LCD Kit Project

Welcome to the first K-LUG project for attaching interesting hardware to a computer so that you will have something interesting to write some code for. When you first look at attaching an LCD to the parallel port it looks simple – a bunch of connections, a potentiometer, and maybe a resistor for the back light. In fact, it can be messy and discouraging. This kit is designed to make the interface simple. It was designed by Dennis DeLorme and Kevin Neff – if you have questions talk to one of us. When attaching an LCD display, there are several options for the control functions. Rather than invent our own, we used an existing definition originally used by a Winamp add-on. The connections are as follows.
