Team TenCupInteractive Beirut Table Keith Arment Brandon Parks Justin Price
Purpose • The TenCup Entertainment Table is an interactive table that enhances the game-play experience of Beirut for both the player and the spectator.
Basic Rules of Beirut • Two teams of two players each starting with ten cups. • Teams alternate shooting two ping pong balls (one for each player) at the other teams cups. • If a ping pong ball is made in the other teams cup that cup is removed. • Teams are allowed to re-rack twice throughout the game (at six, four, three or two cups). • Team that eliminates all ten cups first wins.
Primary Objectives • Scoreboard that keeps track of remaining cups, game duration, and number of racks left. • Sensors that tracks number of cups in play for each team. • Programmable logic that interacts with scoreboards, sensors and other LEDs. • Keep list of upcoming teams waiting to play (Microcontroller) and notify them when they are playing. • Sound interface with LED equalizer and speakers, with ability to add other sound effects.
Table Construction • We will be using items that we could find in our local hardware store to build the table in the ITL • The table top will be built similar to an open box where we can lay all of our circuits in the box and then cover the table with Plexiglass at the end • There will also be a scoreboard at one side of the table
Logic Interface Display and Scoreboard User input/buttons User input/buttons Sensors and Cup Lights Sensors and Cup Lights Programmable Logic Game Start Button
Programmable Logic • State Machine • Use a FPGA device to take input from either side of the table regarding number of cups left as well as user input from buttons (re-rack, re-rack completed, begin game, etc.) • Output from this FPGA will be the items that are needed for the scoreboard as well as the lights under the cups at either side of the table.

User Input/Output Block Diagram User Input (Keyboard) Microcontroller Programmable Logic LED List Display Output to twitter
Microcontroller • This device will be used to receive the majority of the user input • Should display a list of the teams that are to go next as well as be able to progress the list as each game ends • Other applications could be for the controller to make a larger scrolling LED display that could show the names of the current game players as well as the players for the next game.
Twitter • Using a Zigbee to be able to connect the table to twitter • This should make it so that we can send messages out using their social network about the team that is playing next and that the game has ended • Other application could be to keep stats on a computers hard drive away from the table
What We Need BUY • FPGA to program for the score and LEDs involved with game • Analog circuit devices to make the LED equalizer • Microcontroller that can handle all of the user input prior to the game and progress the games along from FPGA, with lists, card input, etc. • LEDs, lots of LEDs MAKE • Make our own sensors using a combination of an inferred emitter and detector • Make a table of wood that is strong and can hold all of our components. Then be able to support Plexiglas on top to keep the circuits away from the elements
Spectator Entertainment • Loudspeaker audio system • In-table graphic spectrum analyzer display connected to the stereo input of the audio system • Push-button accessible mp3 clips to enhance intensity of game-play. • “Trash Talking” audio clips • Ohio Players – “Fire” • “Cheering crowd”
LED Spectrum Analyzer • Takes an input from an iPod or other mp3 device through a standard audio jack and produces a light array via filters at five different frequencies

MP3 CODEC • Utilizes a microcontroller to retrieve MP3 files stored in FLASH memory
Division of Labor • Keith (ECE) - Design and implementation of the FPGA sensors, scoreboard, and buttons. Help with controller and Twitter interface • Justin (EE) - Design and build of the visual equalizer that will display the frequencies of the music in the center of the table • Brandon (EE) – Working with the microcontroller to develop the user input as well as making it able to receive signals from the FPGA to take into account the progress of the games. Communication with Twitter
Possible Additions • Add a scrolling LED that could display the names of the next team • Card reader to make the list • This could either read the persons drivers license for the information or give them a new card
Risks • Not being able to tie our microcontroller to our FPGA effectively this could make it so that it is impossible to tell when the games has ended and move onto the next one • Power could be an issue with the amount of LEDs that we are using. We will have to look to use a power supply that can handle the amount that we will need • Have a hard time being able to interface with Twitter • Over budget
