node-pixel

Use node.js on a Rpi to flip some RGB pixels.

Prerequisites

Running Raspberry Pi with running Occidentalis v0.2. Other distros might work as well.

Have an Adafruit RGB Pixels (WS2801) strand connected to your Raspi like shown here. Other stripes may or may not work.

Install node.js. I used a pre-compiled version of v0.8.15.

Checkout node-pixel.

git checkout https://github.com/tinkerlog/node-pixel

You have to rebuild the spi module.

npm rebuild node_modules/spi

Install additional modules.

npm install node-static
npm install socket.io
npm install easing

Start node.js

sudo node index.js

Have fun.
