GeneraBLE

Generative art from ambient BLE advertisement packets. A work in progress started on #IoTDay 2017 based on our earlier work with midiot and with Philips Hue.

For instructions on how to prepare a Raspberry Pi to run GeneraBLE, see our Experience Generative Art tutorial.

System Overview

Web Interface

The web interface provides dynamic audiovisual scenes that run in-browser. Scenes provide generative, ambient content for HD displays, for example Square Shades:

Hue Interface

GeneraBLE can discover Philips Hue bridges over the local network and drive their connected lights with real-time generative content.

OSC Interface

MIDI Interface

The midi package prerequisites must be met before installation.

Raspberry Pi (and other Linux-based systems)

ALSA is likely to be the only missing prerequisite, and can be installed as follows:

sudo apt-get install libasound2-dev

ZynAddSubFX Interface

If ZynAddSubFX is installed (see our Experience Generative Art tutorial), the zyn interface provides a convenient way to change instruments.

Installation

From the command line, browse to the folder which will contain your project and run.

npm install generable

Hello GeneraBLE!

In the folder where you installed generable (see above), create a file called generable.js and paste the following contents:

var generable = require('generable');
var app = new generable( { httpPort: 3000 } );

From the command line, in the folder which contains your project, run the following:

node generable.js

Point your favourite web browser to localhost:3000 and begin configuration.

Configuration

The intent of the GeneraBLE project is for all configuration to be completed through human-friendly web interfaces. The web interfaces currently supported include: Reel (BLE), Hue, MIDI and OSC.

To reset the configuration to default, simply delete the data/generable.db file and restart the program.
