Dogs of Fate

Press a button, get a dog fortune

There are 7 possible fortunes and 100 possible dogs! I hand-picked 100 dogs from the Dog API and added in a few celebrity dogs too (e.g. friends's dogs, my family dogs, instagram famous dogs). Each dog's vibe matches the fortune.

I have 3 versions of the same script:

• fortune.py - CLI interface
• fortunate-pi.py - Physical button interface connnected to GPIO pins on a Raspberry Pi Zero
• fortunate-gui.py - GUI interface, used on a Rasperry Pi 4 + display

RPI instructions

What to do when starting from a fresh raspberry pi lite install:

On the machine you're sshing from:

• Reset ssh keys so you can ssh in: ssh-keygen -R <HOST>
• Then ssh in

On the raspberry pi:

• sudo apt update
• sudo apt upgrade
• sudo apt install vim git pip
• Set up GitHub ssh keys
• Clone this repo
• cd into fortunate-button
• python -m venv env then install the missing thing
• python -m venv env
• source env/bin/activate
• pip install --upgrade bleak Pillow RPi.GPIO gpiozero (or maybe can use python -m pip install -r requirements.txt?)
• sudo apt-get install libopenjp2-7
• sudo pip3 install Pillow --break-system-packages <- needed for running script with root
• Start script on launch
  • sudo vim /etc/rc.local
  • add:

    sudo bash -c 'source /home/vrk/fortunate-button/env/bin/activate > /home/vrk/blink1.log 2>&1' &
    sudo python3 /home/vrk/fortunate-button/fortune-pi.py &
