Raspberry Pi Settings

UCL Eduroam on Raspberry Pi

add this to /etc/wpa_supplicant/wpa_supplicant.conf

network = {
ssid="eduroam"
key_mgmt=WPA-EAP IEEE8021X
eap=PEAP
identity="#####@ucl.ac.uk"
anonymous_identity="anonymous@ucl.ac.uk"
password="#######"
priority=22357
proactive_key_caching=1
} 

and change line in /etc/network/interfaces for wlan0 from wpa-conf to wpa-roam.

Terminal Shortcut

This is useful for debugging, as we need to have gui running and pygame normally hides everything.

from here Edit the file (on raspbian jessie) leafpad ~/.config/openbox/lxde-pi-rc.xml .

<keybind key="F4">
    <action name="Execute">
        <execute>lxterminal</execute>
    </action>
</keybind>

Better Python Editor

LCD Screen Setup

I got a waveshare 7" screen from amazon, setup guide here. I dont seem to be able to get touch screen working on it but I dont need it for this. To set it up, add the following to \boot\config.txt. You need an adequate power supply for this, I am using RPi3 official one.

hdmi_mode=1
hdmi_mode=87
hdmi_cvt 1024 600 60 6 0 0 0

Schedule dropbox checking task

The dropbox folder is checked every 10 minutes by adding a chron task via the command crontab -e Add the following line at the bottom of the list, has to be full paths.

*/10 * * * * sudo python /home/pi/RPi_Photobooth/dropboxsync.py -d

startup script

Based on useful script here.

Created launcher script launcher.sh which (after waiting a bit to ensure system ready), starts the photobooth whilst logging to a text file with tee. add following line to /etc/rc.local before the exit 0 line

# Auto photobooth
sudo /home/pi/RPi_photobooth/launcher.sh &
