Begin at the Beginning…

Theme: Learning Tools

When we first started brainstorming ideas for our project, we knew we wanted to design something that was:InteractiveChallengingAttention grabbingEducationalFun

developing our strategy
Developing our Strategy:
  • Deterministic Design Process
  • Peer Review Evaluation Process (PREP)

(To see more examples of PREP sheets, please access our website: web.mit.edu/aclare/Public/SSP)

results of our brainstorming
Results of Our Brainstorming:
  • A wooden map
  • A computer game
  • 3D Brain/Eye
  • 3D scrabble
  • Geography game
  • Operation type game
  • Music game, games for the blind
  • Building “Blocks” of Life
functional requirements of body game world puzzle
Functional Requirements of Body Game/ World Puzzle
  • Puzzle lights up and plays music upon completion
  • Sound plays when specific pieces/parts touched and plays info about that piece/part
  • Pieces marked with braille for the blind and textures to facilitate puzzle completion
  • Demonstrate interchangeable parts for different subject areas (geography, human physiology, etc.)

final concept
Final Concept:
  • Wooden Box
  • Plastic Puzzle Bases
  • Lights and Sound
  • Information Wand
  • Different Puzzles
  • Clay 3D Puzzle
circuitry design goals
Circuitry Design (goals)
  • Be able to touch specific pieces and plays information about that piece.
  • When the puzzle is completed, some parts of the puzzle light up.
  • When the puzzle is completed, some sound plays (“Congratulations! You completed the puzzle!”)
info circuit
Info Circuit

Problem: How to play seven pieces of info for seven continents?

Solution: Buy seven sound chips to record sound and play back.

bubble switch

sound chip for the info and congratulation sound

another problem
Another problem

Problem: Each chip comes with one battery and one speaker. If we use seven chips, how to just use one battery and one speaker?

Solution: Use our brains!!!

battery and speaker problem first try not working
Battery And Speaker ProblemFirst try--not working

All the chips are in parallel, and in series with the battery and the speaker.

battery and speaker problem second try working but not practical
Battery And Speaker ProblemSecond try--working, but not practical
  • Accomplished the goal of using one battery and one speaker.
  • Requires a four-pin wand and four corresponding pins on each info spot on the map – impractical.

(DC->square wave)

  • Chose R2=39k Ω and C1=10E-6 F to get the right frequency (approximately 0.5Hz)
congratulations circuitry
“Congratulations” Circuitry
  • magnetic switches in series to control the “congratulations” circuitry
  • lights and sound circuitry in parallel to be triggered by the magnetic switches

Our puzzle design (nail design)

ponder puzzle box
Ponder Puzzle box

Design Parameters:

  • Small enough to fit on a normal desk
  • Large enough to accommodate internal circuitry
  • Grooves to accommodate sliding cover, and additional puzzle overlays
  • Sturdy, but not overly heavy.

  • Decided on wood (easy to work with, strong, relatively light)
  • All woodworking was done in the Hobby shop under the guidance of Ken Stone

  • Each board was made separately using a variety of saws and blades
  • The boards were later clamped and glued with the bottom board being screwed on after the circuitry was inserted and tested

Functional Requirements:

  • Fit together well
  • Imbed magnets to complete circuit
  • Holes to insert wand to hear information

  • OMAX Water Jet layout
puzzle2

  • Used the Water Jet to cut the puzzle
  • Polypropylene material
puzzle3
Puzzle
  • Utilized Crayola Model Magic Clay
  • Pliable at first, but air dries hard and lightweight without crumbling
  • Non-toxic: child-safe
  • Fulfills two functional requirements:
    • 3D to show land textures and elevations
    • Conceals magnets
production
Production
  • Under budget
  • Easy to manufacture
  • Simple design
  • Mold for puzzle pieces
  • Custom circuit boards
further development
Further Development
  • Interchangeable puzzles
  • Use same circuitry, fit the same holes and magnets
  • Mini computer to hold information or each puzzle comes with info cartridge
  • Smaller magnets, more lightweight
future puzzles
Future Puzzles
  • Varying difficulty levels: child to adult
  • Individual continents/countries, solar system, human body, rainforest… endless possibilities!
  • More physically detailed for blind, braille
ponder puzzle
Ponder Puzzle!
  • Sight, touch, and hearing stimulated
  • Lightweight clay, 3D pieces
  • Versatility makes it for all ages
  • Toy for home, study tool, pastime, teaching tool in classrooms
  • Technology meets tradition
