Project Overview What is "Hackers of Catron"? o An electronic Settlers of Catan® board. Settlers of Catan® is a resource gathering and trading board game in which players compete to build the largest economy. What we will improve upon? o The game is really fun, but it takes too long to set up. This project shortens the setup process. o This design makes resource gathering and spending automatic. o Hackers of Catron simplifies the execution of Catan without adding more complexity.

Design Challenges Sense small game pieces at up to 145 specific locations o Hall Effect sensors spaced properly on large PCB o Magnetic pieces o Multiplexed signals Track and automate trading of resources o Web application to be multiple device friendly o Raspberry Pi to act as low-cost web server Display a randomly-generated game board o Color of RGB LEDs denotes resource type o Seven Segment displays denote rarities Create random numbers o Random numbers generated by the Raspberry Pi and microcontroller system clock
Joshua's Contributions Suggested the original idea Hardware o Built Early Prototypes o Estimated Power Requirements o Created Circuit Schematic Researched Patent Liability Plotted High Level Flowchart Microcontroller Programming o Test Functions o Board Resource Generation o Dice Roll o Piece Placement Legality o Longest Road o Raspberry Pi Communication
Spencer's Contributions Suggested use of Raspberry Pi and Operating System o Tested alternative boards o Tested alternative linux distributions o Set up raspberry pi for use Found and tested functions during microcontroller testing Assisted with flowchart creation and layout Designed and developed original web interface o HTML5 and CSS3 Frontend o Python 2.7 backend converted to Python 3 Developed most of the backend of the version 2 web interface o Ported into skeleton structure o Assisted with front end design and development Created parts of the packaging o 3D Printed hexagons
Ryan's Contributions Prototyping Packaging design considerations Test code written for all interfaces Populating PCB Packaging construction Flowcharts and game logic Microcontroller software o Low-level functions o Check for legal piece placement o Main game loop o Relational Map of all positions on the board o Updating the board state Debugging Micro and Pi communication Project Video
Project Specific Success Criteria An ability to generate a random Catan board and represent the resources and their relative scarcity visually. An ability to detect the placement of pieces on the board and update game status accordingly. An ability to display game status (current scores, resources, etc.) via a web interface. An ability to enforce correct turn based gameplay via the board lighting and web interface. An ability to handle resource trading between players via the web interface.
Summary Hackers of Catron is an electronic version of Settlers of Catan ®. Large PCB emulates physical board o Hall Effect sensors detect pieces o RGB LEDs and seven segment displays show generated game board Communication between Raspberry Pi and Microcontroller o Uses I 2 C for communication o Microcontroller acts as EEPROM Slave to Raspberry Pi Raspberry Pi hosts web server and acts as Wi-Fi Access Point o Web application allows players to see/use hand and score All success criteria met
