CS-EE Introduction o Our project - Automatic Ordering o Would reduce downtime during game play University of Portland School of Engineering PallinoBocce Ball Handheld Device Sense Process Actuate

CS-EE Background o Why does order matter in Bocce? o What is a Pallino? o Displaying and updating the order, how? University of Portland School of Engineering

CS-EE System Breakdown University of Portland School of Engineering Oscillator Ckt Speaker Amp Pallino Microphone BPF Amp Comparator PIC RF Module Amp Bocce Ball Representation RF Module LCD PIC Handheld

CS-EE Methods University of Portland School of Engineering Acoustic system o Pallino generates and sends 14kHz signal o BBR receives and processes signal o Problems we encountered

CS-EE Methods (Cont.) University of Portland School of Engineering RF system o BBR sends an RF signal using a PIC and the Xbee RF modules o Handheld receives, processes, and displays the signals. Ball1 Ball2 Ball3 Ball2 Ball3 Ball1

CS-EE Methods (Cont.) University of Portland School of Engineering Worked backwards o Handheld – used knowledge from past classes o BBR – research and past group material o Pallino – research

CS-EE Results: Our System University of Portland School of Engineering Ball2 Ball3 Ball1 Field of Play Players

CS-EE Results: Building the System Founder’s Day University of Portland School of Engineering Oscillator Ckt Speaker Amp Pallino Microphone BPF Amp Comparator PIC RF Module Amp Bocce Ball Representation RF Module LCD PIC Handheld

CS-EE Conclusions University of Portland School of Engineering o Achievements o Our system works o Players cannot hear the tone emitted from the Pallino o This project will help reduce down time in the game o Our project helps players determine which ball is closest to the Pallino o Improvements o Make the system smaller o Use low power electronics

CS-EE Demonstration University of Portland School of Engineering We will be showing a full demonstration of our project in a video.
