2) Construct the scoreboard


  • Cut out the holes in the scoreboard for the LED displays centered on the 1/4 lines, as depicted.



  • Print out the templates found here, cut out and hot glue them to the scoreboard as depicted above. 
  • Color any exposed board material between the template and displays black. 
  • Construct the 5 ribbon cables (4 10-trace cables, 1 20-trace cable) using 10-pin IDC connectors and ribbon cables and protoshield (protoshield depicted below).

  • Wire the displays as depicted below.  Use hot glue to secure the components.


  • Affix the hooks to the back of the scoreboard, as well as the USB extension cable (depicted above).


3) Program the Scoreboard

  • Download the Arduino IDE and install (http://arduino.cc/en/Main/Software).
  • The github repository for my code can be found here.  Check it out into your Arduino working directory (i.e., git clone https://github.com/ScratchesTheItch/ScoreboardArduinoCode.git).
  • Fire up the Arduino IDE, open the GC_Scoreboard sketch file.
  • Upload the sketch to the Arduino.
  • Once loaded, select the Serial Monitor to test the scoreboard. (i.e., enter test into the Serial Monitor in order to cycle the display its test display).

4) Build the Control Box


  • Wire up the control box, as shown (starting from the upper right hand corner, components are 4G Hotspot, USB battery, WiFi AP, and Raspberry Pi).




  • Connect WiFi AP Raspberry Pi via Cat 5 network cable.
  • Connect 4G Hotspot to the Raspberry Pi via USB.
  • Connect the Scoreboard to the Raspberry Pi via USB.
  • Connect the USB Battery to the Raspberry Pi's Micro-USB power port.

5) Configure the WiFi AP


Using the AP Quick Setup menu:
  • Operation Mode:  Standard AP Mode
  • Wireless Operation Mode:  Access Point (AP)
  • Wireless Network Name:  Scoreboard (or whatever you like -- this is the AP name your scorers will join to get their internet)
  • Wireless Security:  WPA-Personal/WPA2-Personal
  • Wireless Password:  (whatever you like--this is the password your scorer will use to join your AP)

6) Configure the 4G Hotspot


  • Hide the Hotspot Wireless network name (under Jetpack Settings / Wi-Fi, uncheck the "Broadcast Wi-Fi name")


7) Setup the Raspberry Pi

  • Install Raspian onto the Raspberry Pi using NOOBS (http://www.raspberrypi.org/help/noobs-setup/).  Sometime during this step, connect the Raspberry Pi to your home LAN via ethernet.
  • Once the Raspberry Pi reboots, ssh in:
    • ssh pi@raspberrypi
  • Using raspi-config (sudo raspi-config):
    • (1) Expand file system
    • (2) Change password
    • (3) Boot to command line
    • (4) Internationalisation Options
      • (I2)  Change Timezone - Change to your timezone to enable proper functioning of box scores
    • (8) Advanced options
      •  (A2) Hostname - Recommend setting it to ScoreboardControl (NOTE:  Do not set to "Scoreboard"or the web server will not work properly due to DNS confusion)
    • Reboot
  • Once rebooted, ssh back in:
    • ssh pi@Scoreboard
  • Update/upgrade and install packages
    • sudo apt-get update
    • sudo apt-get upgrade
    • sudo apt-get install dnsmasq apache2
  • Install the Device::SerialPort and Compress::Zlib perl modules (The following command should work, if not see http://www.thegeekstuff.com/2008/09/how-to-install-perl-modules-manually-and-using-cpan-command/ for suggestions):
    • sudo cpan -i Device::SerialPort Compress:Zlib
  • Download install tarballs into your home directory 
    • cd
    • wget https://github.com/ScratchesTheItch/ScoreboardRaspberryPiCode_Configs/raw/master/configs/configs.tar.gz
    • wget https://github.com/ScratchesTheItch/ScoreboardRaspberryPiCode_Configs/raw/master/tinyproxy/tinyproxy-1.8.3-gcscoreboard-bin.tar.gz
    • wget https://github.com/ScratchesTheItch/ScoreboardRaspberryPiCode_Configs/raw/master/gc-parser/gc-parser.tar.gz
    • wget https://github.com/ScratchesTheItch/ScoreboardRaspberryPiCode_Configs/raw/master/webserver/webserver.tar.gz
  • Unpack tarball in your root directory 
    • cd /
    • sudo tar -xvzf /home/pi/tinyproxy-1.8.3-gcscoreboard-bin.tar.gz
    • sudo tar -xvzf /home/pi/gc-parser.tar.gz
    • sudo tar -xvzf /home/pi/webserver.tar.gz
    • sudo tar -xvzf /home/pi/configs.tar.gz


8) Start Everything Up

  • Plug scoreboard into control box
  • Power on WiFi AP
  • Power on 4G Hotspot
  • Power on Raspberry Pi (i.e., plug into USB Battery)
Once the scoreboard flashes a second time, it is ready for use.  

9) Score a Game

  • On the iPad, join your scoreboard's wireless network using the SSID and password configured above
  • Start the GameChanger app and score game as normal
  • Confirm scoreboard updates as the game is scored

10)Post Game

  • Disconnect USB battery
  • Power down WiFi AP
  • Power down 4G Hotspot
  • Disconnect scoreboard from control box
  • Pack it all up and go home

11) Between Game Maintenance

Three batteries need to be charged:
  • The WiFi AP
  • 4G Hotspot
  • USB Battery (NOTE:  This usually takes the longest)

By my accounting, this should get you from zero to project complete.  If you go through this guide and encounter any issues, please let me know so that I can correct the guide for others.  Thanks!
