Spell Bowl Simulator

• Team members
• Nate Hribar
• Neel Agrawal

4
What is Spell Bowl?

• Spelling competition that differs from
  traditional spelling bee
• Students write down their spellings of the words
  in competition after the words are spoken and
  used in context
• Teams are composed of 8-10 students.
• KES competes at grade levels 4-5

5
Our goals

• Create a simulator that will allow the students
  of KES to prepare for upcoming Spell Bowl
  competitions
• Create a simulator that is both simple and
  user-friendly in interface and at the same time
  true to the style of Spell Bowl
• Provide immediate feedback to the students
• Structure the project in such a way that future
  expansion to other areas (such as Math or Science
  Bowl) is facilitated

6
Implementation

• Text and audio files corresponding to each word
  will be stored
• The students will be prompted on a word-per-word
  basis with the audio files, and will then have 20
  seconds to enter their spelling of the word
• Repetitions of the audio will be available
• Program will be compact and either web-based or
  installed locally

7
Planning

• High-level planning of software organization
• Clarify specifications (e.g. web-based code?)
• Implement and test code
• Enter text and audio data for each word

What is Solar Car?

• A remote controlled car attached with solar
  cells.
• To build a remote controlled solar car and to
  teach the basic principles of energy and
  electricity to KES fourth and fifth graders.
• The remote controlled car will be powered by a
  7.2V-battery and solar cells.

Stoplight

• Team Members
• Yu Gene Wong
• Neel Agrawal

16
What It Does

• Basic idea is to control students noise in
  cafeteria.
• Takes noise inputs through a microphone, sends it
  the microprocessor and it determines if its too
  noisy.
• Lights changes based on the noise level.

Whats next!!

• Currently software part of the project is
  completed.
• Need to adjust inputs into the microprocessor.
• Finalized product will be delivered at the end of
  the semester.

19
Win-dicator/Quiz Bowl

• Win-dicator is a Jeopardy style buzz-in game
• Quiz Bowl game is a modification of the
  Win-dicator

20
Win-dicator/Quiz Bowl

• In a transition period involving the completion
  of the final Win-dicator game, and designing the
  new Quiz Bowl game.

21
Win-dicator/Quiz Bowl

• Win-dicator
• The last box is constructed and hard-wired.
• The circuit is nearly completed.
• The final steps are to integrate the circuit into
  the box, and test the final product.

• Quiz Bowl
• Three main project tasks have been identified.
• 1) Alter existing ABEL code to meet
  specifications.
• 2) Research wireless capabilities of hand
  buzzers.
• 3) Implement relay to connect output from PLDs
  to 12 Volt light bulbs.

22
Four Seasons

• Project Overview
• Transmitter/Receiver Circuits
• Controls the activation of the motors, which
  create motion of the Earth.
• Both circuits were soldered and finished last
  semester.
• The circuits need to be tested and mounted under
  the box.
• Voice Description Circuit
• Gives a detailed, pre-recorded voice description
  about each of the four seasons.
• The record/playback circuitry is working. We
  still need to record the actual messages.
• Playback circuit needs to be interfaced with an
  amplifier and speaker. The amplifier has been
  designed, it still needs to be tested. We need
  to purchase a new set of speakers for the final
  project.

23
Four Seasons

• Project Overview
• Physical Construction
• The box is painted. The children of KES painted
  it last semester.
• A new globe was acquired. We still need to mount
  the receiver circuit inside.
• The plexi-glass has been purchased and cut. A
  plan has been developed for how to design the
  cover.
• All circuitry still needs to be mounted under the
  box. Some circuitry still needs to be soldered.
• We need to provide a power source for all
  circuitry. Design of this is still being
  discussed.
• Documents
• The complimenting workbook is currently being
  revised.
• A users manual still needs to be developed.

24
Conclusion

• Its been a fun semester and we did get a lot of
  things done.
• We hope that our partner is as happy working with
  us as we are working with them.
• Thanks to all the seniors that has put their time
  and efforts into finishing the projects.
