Slide 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

Slide 2

Introduction Building an Electronic Dartboard ("ED") that naturally monitors score Recreational movement for an assortment of potential clients Automation is given by electronic framework Sensing Array Intermediate equipment for information transmission Software for calculation and yield

Slide 3

ED's Design horse hair/stopper dependable scoring smooth outline direction estimate any standard darts Background Dartboard available made out of plastic extremely temperamental ugly not control utilize plastic darts

Slide 4

Motivation Darts are a fun recreational action Project deliverable fun and pleasant End arguments about scoring, swindling No more extended in charge of scorekeeping, more concentrate on fun and gameplay Great to demo for SDP06

Slide 5

Overview Sectionalized board Sensing gadgets Data Transmission Software Combine into utilitarian outline

Slide 6

Long-term objective MDR Working solid sense framework Efficient information transmission Final Design All areas working Accurate scoring

Slide 7

The Present Situation Researched equipment specs All sensors are on request (various choices) Micro-controllers picked Chose serial transmission Overall arrangement settled upon

Slide 8

Development up to present Members looked into changed sensors Spare dartboard for execution Extra parts for testing Sensors consented to test Strain gages, Piezoelectric, Push-Button Sensor rejected Laser matrix (cost, unfeasible usage)

Slide 9

Potential Alternatives Strain gages weight connected resistance goes up make resistor circuit for voltage contrasts Pros Simple plan Sensitive to weight Low cost Cons Is it excessively touchy?

Slide 10

Potential Alternatives(contd.) Piezoelectric Disturbance in Quartz precious stones on Piezo material actuates a voltage Pros Low cost Piezo material can cover zone required Good affectability Cons Could harm Piezo film with darts

Slide 11

Potential Alternatives(contd.) Pushbutton Spring is packed, voltage flag yield Pros dependable diverse sizes, shapes, springs Low cost Cons affectability of weight connected spring constants

Slide 12

System Block Diagram

Slide 13

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

Slide 14

Microprocessor Receive Data Store Data Convert Data Transmit Data Serial Connection

Slide 15

Computer Program Store Data Compute Data Display Data GUI

Slide 16

Proposed MDR Specifications at least one detecting choices working Operational sensor connected to segments on dartboard Serial transmission of bits to PC Computer perceives values appointed to areas

Slide 17

Conclusion Automatically keep track of who's winning Efficient and Reliable Sensing Values perceived and Displayed on GUI Overall fun and bother free gameplay!
