The modified files are the ones provided here.

To use blink.py and poweroff.py, you need to plug a LED to pin 17 and ground on the pi. Otherwise you can remove the lines in run_eeg.sh.

The auto recording and auto shutdown is made through a systemd service:

1. Create a file at /etc/systemd/system/eeg.service containing or copy the one from the repository:

[Unit]
Description=Start recording with Olimex EEG

[Service]
User=pi
WorkingDirectory=/home/pi/eeg
ExecStart=/home/pi/eeg/run_eeg.sh
Restart=never

[Install]
WantedBy=multi-user.target

2. Reboot or run systemctl daemon-reload as root
3. Enable the service to start it on boot using systemctl enable eeg.service as root
