BrainBeats Desktop

This repository contains the desktop client for brainbeats suite. At it's core, it's an electron application for creating audio samples out of brain waves.

Development

Primary Dependencies:

If working with the EEG headset:

OpenBCI GUI

The desktop client was developed primarily on Mac with EEG integration done on Windows. If there are no intentions to use EEG dependent parts of the client, installation guidelines for python dependencies can be skipped.

Ports

During development, the various parts of the application run in the following ports:

React: localhost:3232

Install

Max/Linux base package

Run npm install

Windows base package

Run npm run install_windows

Python dependencies (cross platorm)

Python dependencies can be installed on your system or within an environment (recommended).

Optional: Create and activate environment
- Install virtualenv on your system
  - Mac/Linux: python3 -m pip install --user virtualenv
  - Windows: py -m pip install --user virtualenv
- Create environment
  - Max/Linux: python3 -m venv env
  - Windows: py -m venv env
- Activate environment
  - Mac/Linux: source env/bin/activate
  - Windows: .\env\Scripts\activate
- Check that environment has been activated
  - Mac/Linux: which python should print .../env/bin/python to terminal
  - Windows: where python should print .../env/bin/python.exe to console
Install python dependencies: pip install -r hardware/requirements.txt

Run

Mac/Linux

Run npm start

Windows

Open up two terminals
In one terminal, run npm run start_windows
In the other terminal window, run electron . in this same root directory

Build

Mac/Linux

Building the application transcribes all the components and plugins down to simple html and javascript files to be used for distribution. It also copies over all the hardware and setup files to the production folder. It does not create the distribution binaries for the electron application. To create the binaries, a separate setup such as electron forge, or electron builder should be used.

Run npm run stage_production to build production files
Run npm run start_production to start up electron using built files. Running without staging files will error out.
- If you're planning on using the EEG headset, make sure python dependencies have already been installed.

Windows

First run this command in Powershell, for some reason npm doesnt play nicely with Powershell commands: Remove-Item -Recurse -Force -Path production/; mkdir production/; npm run build_prod_windows; Copy-Item -Recurse -Force -Path hardware/ -Destination production/; Copy-Item -Path production_modules/main.js -Destination production/; Copy-Item -Path shared_variables.json -Destination production/; Copy-Item -Path preload.js -Destination production/
Then run: electron production/main.js
