Follow score and rank players for your football table games, using a raspberry-pi. Not a new idea, but never found a complete solution.

You'll need:

• Football table
• Raspberry-pi B+ with 2016-02-09-raspbian-jessie-lite clean
• An HDMI screen (to display current game scoreboard)
• Two arcade plunger buttons (to increment score and interact with scoreboard)
• Lot of wires
• Basic shell understanding

And you'll get:

babpi can be run straight from your dev machine with:

npm install
npm run dev

Then just open http://127.0.0.1:3000/ in your favorite browser. You can mock the button interface by pressing a, A, b and B.

Let's start with a fresh raspberry pi:

# Update system
sudo apt-get update
sudo apt-get upgrade

# Install chromium 48
cd
wget http://ports.ubuntu.com/pool/universe/c/chromium-browser/chromium-browser_48.0.2564.82-0ubuntu0.15.04.1.1193_armhf.deb
wget http://ports.ubuntu.com/pool/universe/c/chromium-browser/chromium-browser-l10n_48.0.2564.82-0ubuntu0.15.04.1.1193_all.deb
sudo dpkg -i chromium-browser-l10n_48.0.2564.82-0ubuntu0.15.04.1.1193_all.deb chromium-browser_48.0.2564.82-0ubuntu0.15.04.1.1193_armhf.deb

# Install node
cd
wget http://node-arm.herokuapp.com/node_latest_armhf.deb
sudo dpkg -i node_latest_armhf.deb

# Install babPi (this)
cd
sudo apt-get install git
git clone https://github.com/dav-m85/babpi.git
cd babpi
npm install
npm install onoff
npm run build

# Setup GPIO
cd wiringPi-b0a60c3/
gpio -v
gpio readall
gpio mode 0 up

# Replace /home/pi/.config/lxsession/LXDE/autostart with the following lines
@lxpanel --profile LXDE
@pcmanfm --desktop --profile LXDE
#@xscreensaver -no-splash
@xset s off
@xset -dpms
@xset s noblank
unclutter -idle 0
gpio mode 0 up
node /home/pi/babpi/server.js </dev/null >/home/pi/babpi/server.log 2>&1 &
chromium-browser --kiosk http://192.168.0.107:3000/scoreboard --incognito

There's still a few things I would like to improve:

• Stat endpoint
• Ranking page with TrueSkill algo, could use http://www.moserware.com/2010/03/computing-your-skill.html, and even https://github.com/freethenation/node-trueskill
• Deal with longClick and shortClick on the GPIO
• Autocomplete player in book page
• Competition mode
• Proper build to ease installation
• Propose a wireless version with a low energy transceiver.
• long click cancel point instead of canceling game
• long click on both sides cancel the game
• On win screen, long click replay
