Chroma lights is a frame work for running annimations for led lights over OSC.

sudo easy_install virtualenv

virtualenv env # or replace 'env' with whatever folder  you want your environment in

source env/bin/activate

pip install -r dependencies.txt

You'll want to activate your virtualenv if it's not already. In your chrome-scripts folder (after having set everything up above before), source env/bin/activate. In order to run the animations locally, we provide a lights emulator written in Processing.

To run the light emulator: $ emulator/lights_emulator

To run an animation: $ ./run.py [animation name]

To contribute add a new folder in the animation directory. This folder should be have a unique name for the animation. The folder must contain the following two files:

main.py:

import sys
sys.path.append("./osc")
from oscapi import ColorsOut
...

manifest.json:

{
	"name":"Random Colors",
	"description":"Random colors on 3 second intervals",
	"creator":"RJ and Reed"
}

Each light recieves an input that is a tuple (r,g,b) where each of r, g, b can be 0-1023.

Construct an array of tuples and send them to the OSC server with

pix = [(1023.0,0.0,0.0)]*24
out = ColorsOut()
out.write(pix)

To add simple effects, such as automatic fade-in and fade-out of pixels, use the animations library in place of ColorsOut

from animations import FadeAnimation
pix = [(1023.0,0.0,0.0)]*24
out = FadeAnimation()
out.FADEINRATE = 2.0 #optional
out.FADEOUTRATE = 8.0 #optional, makes things 'trail off'
out.start()
out.write(pix)

Chroma is bright, and can easily be the predominant lighting in the room. Fast blinking of the lights can be intense, so be considerate.

• Avoid instantaneous changes in both intensity and color
• Use the provided animation framework to transition between colors
