Klondike Elemntary School

• Spring 2007 Final Presentation

2
Magic Piano

• Albert Kim, Sean Lee, Ken Little, Dan Matson,
  Suenghyun Park

3
Motivation

• This project was inspired by the thought that
  many people have a hard time learning musical
  instruments through standard practice, so a
  visual learning tool would be great way to begin
  learning an instrument like the piano.

4
Goals

• Modify a teaching piano so that it will be
  usable for elementary school children
• Make a child safe case for the keyboard to
  prevent accidents or injury
• Create a piano that helps children visually
  identify notes through color corresponding keys

5
Progress

• Changed all LEDs in the keyboard
• Allowed KES to test the keyboard
• Constructed frame for case
• Began fiberglass and paint prep for case

Status

• Frame is ready for final fiberglass touch-ups and
  paint prep
• Keyboard is ready for use

10
Future Plans

• Finish case with final fiberglass layer
• Paint finished case with automotive paint
• Create software package for easy song conversion
  to be used by the KES instructor

Indiana History Game

• Engineering Projects in Community Service
• Klondike Elementary School Team
• Final Presentation
• Spring 2007

12
Project Objective

• Create an interactive game for 4th Grade students
• Over 200 Questions and answers about Indiana
  History
• Game board is map of Indiana
• Students answer questions correctly in order to
  move around the board
• First team to travel start to finish wins!

13
Project Design Details

• Students will travel around 11 cities in four
  teams (red, blue, green, yellow)
• Colored lights (LEDs) at each location will
  match team colors
• Lighted path from location to location
• Colored buttons for each team
• Questions asked via LCD screen
• Button to advance teams location upon each
  correct answer
• Enough questions to ensure there will not be
  duplication

14
Game Board Design

• Done in CATIA V5 R16
• 1/2 material
• Indiana border
• Background color
• Womens Penitentiary
• CATIA Drawing

15
Game Board Design

• Cities Included
• Evansville (start)
• Terre Haute
• Bloomington
• New Albany/Clarksville
• Anderson
• Muncie
• Fort Wayne
• South Bend
• Gary
• West Lafayette/Lafayette
• Indianapolis (finish)

16
General Design Details

• Game board size 31 x 21X 3
• Picture will accompany each city
• Questions are from current text books
• Questions and answers relate to units of study in
  classroom
• Questions are designed to meet the Indiana
  Educational Standards

17
Prototype of Game Board

• Actual size
• Quick idea and visual

18
Design SpecificationsGraphics

• There will be a small icon at each of the 11
  locations on the board.
• Each graphic will have significance to the
  specific city and will include a small caption
  explaining the graphic.
• This will make the appearance more appealing to
  the younger children and be effective in teaching
  Indiana facts.

19
Graphics
Evansville is a very industrialized city. They
are avid producers in aluminum, plastic, coal,
and oil.
New Albany, located on the Ohio River, was
originally a major steamboat center.
The capital of Indiana, Indianapolis, is home to
the Indy 500 car race.
20
Sample Questions Answers

• What road did the government begin in 1811? -The
  National Road
• What general and his Confederate troops raided
  Indiana in 1863?
• -General John Hunt Morgan
• What year was the population of Indiana
  determined to be enough for statehood? -1815

21
Electrical Design Details

• BASIC Stamp microcontroller as main controller
• Programmable logic devices at each location as
  auxiliary controllers (Programmable Logic
  Devices)
• Software program in each device
• 4 colored buttons for teams
• Power on/off switch (cycling on/off will reset
  circuit)
• Button to show answer to current question
• Button to advance team after correctly answered
  question
• LED for each team color at current location will
  be illuminated at all times
• Multi-color (RGB) LEDs will light up with team
  color in sequence to show movement to new
  location
• Separate circuit boards for different sections

22
Semester Accomplishments

• Finalized concept for game board surface
• Developed 210 questions and answers
• Questions were approved by teacher
• Created CAD drawings of game board
• Finalized electrical circuit components
• Completed software for all PLDs
• Began working on microcontroller software
• Purchased most of the electrical parts
• Prototype game board constructed
• Began prototypes of electrical circuits
• Documented work for future semesters

23
Next Semester Goals

• Develop additional questions
• Begin construction of final game board
• Finish writing software for microcontroller
• Finish building electrical circuits
• Test game prototype
• Construct and deliver final game

24
Weather Tracker

• Ben Yoder (Project Leader)
• Vaibhav Sahgal
• Michael Cyb
• Tarun Chadha

25
Overview Specifications

• The purpose of the Weather Tracker project is to
  collect weather information via sensors and
  display this information on a stand-alone console
  with the use of a microcontroller
• This project will provide students useful
  educational information about the elements of
  weather and how they are measured

26
Final Design Solution

• Using a microcontroller and a set of sensors to
  collect and display data

27
Wireless Sensors--Motes

• Front end of sensory network
• Motes are mesh networked
• Base station mote communicates with another mote
• Above mentioned mote communicates to others
• Can be adapted to measure parameters other than
  temperature

Prototype

• Three wireless motes acquired from Professor
  Evans research group
• Motes contain internal thermocouple
• Base station mote to be connected to MIB 520
  gateway

Reason for choice

• Low power 8-bit microcontroller
• The mica2 51 pin expansion connector supports
  analog inputs, digital I/O, I2C, SPI and UART
  interface
• Transfers data through mote and sensor board
  through a UART interface

Weather Tracker

• As of now, we are able to send and receive one
  sensor value wirelessly
• Next, we are going to build up the sensor network
• Finally, we are going to implement the rest of
  the design
