PDR PRESENTATION
introduction
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
background
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
motivation
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
overview
Overview
  • Sectionalized board
  • Sensing electronics
  • Data Transmission
  • Software
  • Combine into functional design
long term goal
Long-term goal
  • MDR
    • Working reliable sense system
    • Efficient data transmission
  • Final Design
    • All sections working
    • Accurate scoring
the present situation
The Present Situation
  • Researched hardware specs
  • All sensors are on order (multiple options)
  • Micro-controllers chosen
  • Chose serial transmission
  • Overall plan agreed upon
development up to present
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)
potential alternatives
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?
potential alternatives contd
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
potential alternatives contd11
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
dartboard electronics
Dartboard Electronics
  • Pressure sensors
  • A/D Converter
  • Foot Line Sensor
  • Power supply
microprocessor
Microprocessor
  • Receive Data
  • Store Data
  • Convert Data
  • Transmit Data
  • Serial Connection
computer program
Computer Program
  • Store Data
  • Compute Data
  • Display Data
  • GUI
proposed mdr specifications
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
conclusion
Conclusion
  • Automatically keep score
  • Efficient and Reliable Sensing
  • Values recognized and Displayed on GUI
  • Overall fun and hassle-free gameplay!
