Begin at the Beginning…: 

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: Interactive Challenging Attention grabbing Educational Fun

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

The Ranking of the Strategies:: 

The Ranking of the Strategies:

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. power bubble switch speaker mic 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!!! power bubble switch speaker mic

Battery And Speaker ProblemFirst try--not working: 

Battery And Speaker Problem First try--not working All the chips are in parallel, and in series with the battery and the speaker.

Battery And Speaker ProblemSecond try--working, but not practical: 

Battery And Speaker Problem Second 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.

Battery And Speaker ProblemThird try—the way to go!: 

Battery And Speaker Problem Third try—the way to go! Use op-amps as input adders. 741 741 Op-amp Op-amp speaker potentiometer 9V 10kΩ 10kΩ 10kΩ 10kΩ 10kΩ 10kΩ 10kΩ 10kΩ 10kΩ 10kΩ 10kΩ 10kΩ 10kΩ 10kΩ 10kΩ 1k Ω

Flashing Lights: 

Flashing Lights 555 Timer (DC->square wave) Chose R2=39k Ω and C1=10E-6 F to get the right frequency (approximately 0.5Hz)

Flashing Lights Wired Up: 

Flashing Lights Wired Up

“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

Info Switch 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.

Ponder Puzzle box: 

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

Ponder Puzzle box: 

Ponder Puzzle box 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

Puzzle: 

Puzzle Functional Requirements: Fit together well Imbed magnets to complete circuit Holes to insert wand to hear information

Puzzle: 

Puzzle OMAX Water Jet layout

Puzzle: 

Puzzle Used the Water Jet to cut the puzzle Polypropylene material

Puzzle: 

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

Demonstration: 

Demonstration

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
