I have started working on my Halloween lighting here at the house. My setup is three OLA (Open Lighting Architecture) nodes and LightFactory
1 universe output as the console. To the left you can see one of my OLA nodes. The node receives Art-Net dmx over ethernet and outputs it to the Enttec Open Dmx controller. which is plugged in to a dimmer pack that controls a Fresnel. the other nodes use Enttec’s usb dmx pro instead.
you can see a youtube video of the system in action here or with out commentary here.
