EnfocaBrain is a data collection system for electroencephalography (EEG) power spectrum, NeuroSky eSense (Attention and Meditation) with MindWave Mobile 2 and environmental data with CCS811 sensor.

• Raspberry Pi (e.g. 4 Model B)
• CCS811 Sensor
  • Connect CCS811 Sensor to raspberry
• Neurosky Mindwave Mobile 2
  • PyBluez and python-dotenv (to run Mindwave Script alone)
  • python-mindwave-mobile installed as a module
• ThingsBoard (optional)

Clone the repo.

git clone https://github.com/jmainhard/enfocabrain.git

Make a virtual environment to install Adafruit CircuitPython and read data from Raspberry I2C.

python3 -m venv venv
source venv/bin/activate

Install packages from requirements.

pip install -r requirements.txt

Configure device token on .env. You can copy an example from .env.example

Also you can make sure that I2C is connected using i2cdetect

i2cdetect -y 1

This will display a grid of addresses with the addresses of all connected I2C devices. If your device is connected and powered on, you should see its address in this grid. If you don't see your device's address, this indicates that there is a problem with the connection, power, or address of the device.

To start enfocabrain automatically when the RP is booted write this to /etc/rc.local before exit 0 (replace the path with the actual one where you cloned the repo)

sleep 10
python3 /home/equipo1/enfocabrain/read_mindwave_mobile.py  > /home/equipo1/enfocabrain/mindwave.log 2>&1 &
/home/equipo1/enfocabrain/.venv/bin/python3 /home/equipo1/enfocabrain/main.py > /home/equipo1/enfocabrain/main.log 2>&1 &

Alternatively you can run the python scripts manually.

For reading from the mindwave mobile 2, first turn it on and then run:

python read_mindwave_mobile.py

For reading data from CCS811 start ccs811.py from the previosuly built virtual environment.

(venv) python cccs811.py
