  1. SpaldingGymnastics Scoreboard Advisor: Zhao Zhang Team Members: Chris Chambers Christopher Reis Alex Dean Luke Breuer Client: Spalding Advisor: Zhao Zhang Team: May 13-01

  2. Problem statements: • Client needs a more sufficient way to display multiple event scores. • The target consumers are athletic venues who hold gymnastic events. • Adaptable to other indoor events.

  3. Functional Requirements • Able to be read from 100’- 200’ away • Easy transportation (Size matters) • Powered by external 120 VAC source (General wall outlet) • Controlled by computer • Wireless communication from computer to message board (WiFi) • Message board relatively insulated from elements in indoor facilities (Humidity)

  4. Concept sketch Main Ideas • Small enough to transport • Displays four different event names on the left • Scrolls through athlete names and scores for each event on the right

  5. Concept of operation

  6. System Description

  7. User interface HTML Website Reasons: • The IC we are using will include a USB port for a WiFi dongle • Allows score reports to be accessed via handheld device (If you can connect to the internet) • Allows user to use any computer to program the scoreboard

  8. Micro-controller unit Beagle Bone Reasons: • Embedded Linux (Angstrom Distro) • Interfaces with LED Drivers • Acts as Ad-Hoc router/HTML Server • Enables complex code to be abstracted (USB, TCP/IP, etc)

  9. LED circuit matrix Reasons: • Reduction of GPI/O pins • Persistence of vision • Matrix operation • Reduction of power consumption • Reduction of discrete components

  10. PCB Schematic

  11. PCB Layout

  12. Led options • Four options • Three Red options • One RG option • Vary in luminosity from 54-220 milli-candela • 1206 Surface Mount packaging (606 for RG LED)

  13. Power system Buck converter Reasons: • Allows 120 VAC Input • Convert Down to 12 VDC to power LED’s • Use Linear Dropout Regulator to convert to 5 VDC to operate BeagleBone and Driver logic.

  14. Functional Breakdown

  15. Non-functional requirements • Powered by a battery source • Built to withstand outdoor weather conditions • Ability to be mounted on stands • Ability to be integrated with other boards

  16. Work Plan Phase 1 – Small scale testing and proof of concept design – Power consumption analysis Phase 2 – Large scale hardware layout and design – Drafting of external components Phase 3 – Prototyping and assembly of components Phase 4 – Extensive testing and analysis of prototype Phase 5 – Report on final results and correction of errors

  17. Possible Development Issues Problem 1 – Programming in HTML –Setting up router Problem 2 – Code to interface with LED Drivers Problem 3 – Developing the mounting system Problem 4 – Time constraint on adding in non-functional requirements Problem 5 – Network Security

  18. Mitigation plan HTML/Router – Work with advisor (Dr. Zhang) LED Drivers – Prototype early in January Mounting – Develop plan with customer to provide mounting system Time Constraint–Set realistic time goals, invest in early development work

  19. Facility visit • Spalding/AAI Manufacturing Facility (Jefferson, IA) • Point of Contact: Norm Robbins • Onsite visit with client’s team • Tour of assembly lines • Gained familiarity with Spaldings manufacturing capability • Discussion of rotary forming capability

  20. budget AND ORDERING

  21. Overall idea of project Allow athletes and fans to receive live updates of scores either via scoreboard or on the web.

  22. Questions? Luke Breuer Alex Dean Chris Chambers Christopher Reis
