biofeedback-cube
This project began as an immersive cube of side 4 feet in which one would sit while hooked up to a heartrate monitor. 5 walls of the cubes were to be LED panels while the base was constructed of wood and contained a 12" JBL subwoofer and fullrange speakers. The heartbeat signal would modulate all light and sound reaching the user providing an immersive biofeedback loop.
OSC is used as a communications protocol between subsystems such as the heartrate monitor, TouchOSC, or Ableton Live.
I constructed 3 panels and the initial project has pivoted. Now the main usage is driving one of them which is mounted on a wall in a wood frame, controllable by TouchOSC and Ableton.
development
While the target platform is a Rasbperry Pi to drive the LEDs, a simulator is included to enable developing on a mac.
pip install -e .
cube --simulator
installation
installed on raspbian jesse: https://www.raspberrypi.org/downloads/raspbian/
Dotstar LED interface requires https://github.com/adafruit/Adafruit_DotStar_Pi (now deprecated) It required patching for Python 3 via this thread: adafruit/Adafruit_DotStar_Pi#24 (comment)
Development on Adafruit_DotStar_Pi moved to https://github.com/adafruit/Adafruit_CircuitPython_DotStar Moving to this requires supporting CircuitPython on rpi
Numpy/scikit requirements are supplied by BerryConda 3 Install that, then
conda install conda-build
conda develop .
This should result in a cube command. Install the systemd/cube.service service in /etc/systemd/system, run systemctl enable cube and it should start on boot up.
Set any environment variables in /etc/cube_environment.
