NPM

Artnet Weblight

Use your Browser as an Artnet lighting device!

It supports dimmer, red, green and blue channels as well as border, blur and images.

Installation: npm install -g artnet-weblight Start: weblight

Start from source with node weblight.js. Webinterface will be available at localhost:3000. It uses standard Artnet port 6454.

Devices

Each virtual device has 10 channels. First device 0 starts at channel 1, second device 1 at channel 11 and so on...

50 devices are possible on one universe (one instance of this application).

Access devices via address:port/device#, e.g. localhost:3000/0.

Images

The images can be placed in /images. Every image has 10 dmx-values where it is visible. The images can/should be numbered XX.filetype (e.g. 1.png) for preserving correct order.

Image 0 is empty. So you can use 25 images. Images are channel 6.

Channels

  1. Dimmer
  2. Red
  3. Green
  4. Blue
  5. Border size
  6. Blur (for Border)
  7. Image overlay

Debugging Artnet

Use http://localhost:3000/0?debug for debugging values.

Frame View

Use http://localhost:3000/frames to see the first four devices on one page with debug info enabled.

Configure Frame view with params count (default 4) and debug (default true). Starting device can be varied by using another frame-id, e.g. /frames/10.

Example: http://localhost:3000/frames/10?count=5&debug=false

Testing

For Testing you can use https://github.com/mtraeger/dmx-webcontrol and configure a (separate) universe like this:

"monitor": {
    "output": {
        "driver": "artnet",
        "device": "localhost"
    },
    "devices": [
        {
            "label": "Monitor 1",
            "type": "artnet-weblight",
            "address": 1
        },
        {
            "label": "Monitor 2",
            "type": "artnet-weblight",
            "address": 11
        },
        {
            "label": "Monitor 3",
            "type": "artnet-weblight",
            "address": 21
        }
    ]
}

Notes

Some sort of color correction can be done by using the dimmer channel to reduce the overall brightness of the rgb channels. Dimming down to e.g. 80% can bring the monitor colors more towards your physical devices.

Todo

  • Config-File
  • circle radius
  • color correction - adopt to physical devices (e.g. by predefined dimmer factor to reduce collor brilliance)
  • show identifier (and debug info) via dmx - maybe on image channel
  • web interface for selecting images / videos + maybe upload
