  1. Electronic Dartboard (ED) Azum Z. Ali, Jason Ngo, Matthew O’Connell, Han Truong Faculty Advisor: Prof Massimo (Max) V. Fischetti Thursday, October 13, 2005 PDR PRESENTATION

  2. Introduction • Building an Electronic Dartboard (“ED”) that automatically keeps track of score • Recreational activity for a variety of potential customers • Automation is provided by electronic system • Sensing Array • Intermediate hardware for data transmission • Software for computation and output

  3. ED's Design horse hair/cork reliable scoring sleek design regulation size any standard darts Background • Dartboard on the market • made out of plastic • very unreliable • unattractive • not regulation • use plastic darts

  4. Motivation • Darts are a fun recreational activity • Project deliverable fun and enjoyable • End disputes over scoring, cheating • No longer responsible for scorekeeping, more focus on fun and gameplay • Great to demo for SDP06

  5. Overview • Sectionalized board • Sensing electronics • Data Transmission • Software • Combine into functional design

  6. Long-term goal • MDR • Working reliable sense system • Efficient data transmission • Final Design • All sections working • Accurate scoring

  7. The Present Situation • Researched hardware specs • All sensors are on order (multiple options) • Micro-controllers chosen • Chose serial transmission • Overall plan agreed upon

  8. Development up to present • Members researched different sensors • Spare dartboard for implementation • Extra parts for testing • Sensors agreed to test • Strain gauges, Piezoelectric, Push-Button • Sensor rejected • Laser grid (cost, unfeasible implementation)

  9. Potential Alternatives • Strain gauges • pressure applied resistance goes up • create resistor circuit for voltage differences • Pros • Simple design • Sensitive to pressure • Low cost • Cons • Is it too sensitive?

  10. Potential Alternatives(contd.) • Piezoelectric • Disturbance in Quartz crystals on Piezo material induces a voltage • Pros • Low cost • Piezo material can cover area needed • Good sensitivity • Cons • Could damage Piezo film with darts

  11. Potential Alternatives(contd.) • Pushbutton • Spring is compressed, voltage signal output • Pros • reliable • different sizes, shapes, springs • Low cost • Cons • sensitivity of pressure applied • spring constants

  12. System Block Diagram

  13. Dartboard Electronics • Pressure sensors • A/D Converter • Foot Line Sensor • Power supply

  14. Microprocessor • Receive Data • Store Data • Convert Data • Transmit Data • Serial Connection

  15. Computer Program • Store Data • Compute Data • Display Data • GUI

  16. Proposed MDR Specifications • One or more sensing options working • Operational sensor applied to sections on dartboard • Serial transmission of bits to computer • Computer recognizes values assigned to sections

  17. Conclusion • Automatically keep score • Efficient and Reliable Sensing • Values recognized and Displayed on GUI • Overall fun and hassle-free gameplay!
