raspberry pi as a DMX light controller
Having jumped in on the early round of the raspberry pi project, I found it made a nice platform for connecting native c++ code to other devices. In this experiment, I wanted to connect a USB DMX controller that I built a while back to a lighting rig to animation a haunted house project.
To do this, I used the native GUI color wheel widget to a bit of code that sent DMX commands via a USB connection to the controller. In realtime, you can modify the color wheel on the raspberry pi to directly control the light fixtures. This opened the door to experimenting with more complex light sequencing experiment by laying the foundation for control.
