    Dscf9795

    Title: 2 of the super stars of Sesame Street
    Description: Just simply press Elmo’s nose then flip or shake the stick to make giggling and silly sounds of Elmo and Cookie Monster.

    Dscf9798

    Title: HA HA HA HA
    Description: Apparently this toy attempts to make people laugh. At least I was enjoying playing with it.

    Dscf9805

    Title: SESAME WORKSHOP
    Description: I just tried to record every text it has on its plastic shell. Everything looked good except the material of this sound maker is not recyclable. If they could use Eco-friendly materials, that would be great!

    Dscf9810

    Title: Dissection
    Description: Inside Elmo’s brain is the place of putting batteries. By looking at little holes on Cookie Monster’s head, we can infer that they put a speaker here.

    Dscf9812

    Title: Let’s see what’s in its body
    Description: Every components are placed stably and neatly in the stick-shaped plastic shell. The nose is bound with a mode switch which I’ll show later.

    Title: Stay orderly
    Description: Sensors and switches are covered and fixed with plastic lids. In the right bottom picture, two of wires were soldered to connect the batteries.

    Dscf9822

    Title: Mode switch
    Description: By pressing this tiny button, I could change the mode of music.

    In mode 1 – giggling of Elmo and Cookie Monster
    In mode 2 – silly sounds
    In mode 3 – brisk music

    Dscf9831

    Title: Power switch
    Description: This little switch is used to control the state of power supply.

    0 – cut off the connection with batteries.
    1 – turn on!

    Dscf9838

    Title: Its heart
    Description: The front view of the circuit board. Wires are hidden behind the board.

    Dscf9855

    Title: Turn around
    Description: There are two capacitors on the back and wires are fastened with hot glue.

    Dscf9841

    Title: Time to make some music!
    Description: This is the sensor detecting the toy’s movement and triggering the chip to play music. There are total 2 sensors inside, one is used to trigger Elmo’s giggling while another one is to trigger Cookie Monster’s.

    Dscf9861

    Title: Done!
    Description: These are all the components of the toy include a narrow strip of tape to hold wires.

    After all the work, I put those electronic parts into a sock monkey that I sewed as a prototype of my final project toy. Monkey toy would make sounds when it is shook. And monkey’s nose is the mode switch. Basically, it does the same thing as the elmo music maker but with a soft "container".

    02 Disassemble A Giggle Ball 

    Click on each picture to enlarge it.

    Dscn9985
    Dscn9986Dscn9988
    Dscn9989

    01 PACKAGE DESIGN OF THE GIGGLE BALL
    It is designed for 18-month-old and beyond, so it is a pretty universal and simple toy.

    Dscn9991_2
    Dscn9990_3

    02 TWO SIDES OF THE TOY
    This is called double fun giggle ball. There are two characteristics  which are  Cookie Monster(BLUE) and Elmo(RED) installed with their two different sounds and appears. After you press on their faces, it will shake and giggle with their sounds.

    Dscn9993
    Dscn9992

    03 TAG ON TOY
    Material: Polyester Fibers, Polyurethane Foam
    Made in China, Fisher-Price, Inc., Surface washable only

    Dscn9994Dscn9995

    04 VELCRO AND COTTON THREAD
    It has a easy opened velcro seam. As pictures, inside is a plastic ball sewed to the surface by simple cotton thread.

    Dscn9996Dscn9997

    05 BATTERY NOTE
    So I cut off the thread and pulled the plastic ball out. The ball is heavy and solid with plain white cover, and it said 2 AA battery required on its bottom where batteries placed.

    Dscn0003Dscn0004

    06 COLOR CODED SENSOR
    There are two lines connected to sensors on each side of the fiber cover. One is blue linking to Cookie Monster’s face. Another is red attached to Elmo’s. The right picture shows where the speaker installed.

    Dscn0008Dscn0007

    07 SENSOR = BUTTON
    Going along the line, I found two small press-sensors sewed and covered by cotton and fabric. Then I cut some thread to took them out. They are two cute small buttons.

    Dscn0009Dscn0011

    08 OPEN THE BALL
    To avoid making it giggle while I was disassembling it, I took out two AA batteries. And I unscrewed four screws fixing the cover of the ball and  took it apart. There are two side of the internal. Upper side installed with a speaker, and the lower side installed a motor and a Printed circuit board. All of them are fixed by screws and connected with each other through colorful lines.


    Dscn0012Dscn0013

    09 SPEAKER
    I unscrewed the speaker. It was a thin, round, plastic-like chip.

    Dscn001610 PCB’s back
    There is a written XY and a transistor on the board’s back which faced upward.

    Dscn0018

    11 PCB’s front
    Printed circut and colorful lines connected to different parts.
    Red on the left upper- Elmo’s sensor.
    Blue on the left upper- Cookie Monster’s sensor.
    Yellow- speaker.
    Green and blue on the left bottom- motor
    Red and Black on the right- batteries

    Dscn0019
    Dscn0022

    12 MOTOR
    The motor uses gears to rotate a weighty metal to keep changing the center of gravity. That is why the ball can keep shacking while it is giggling. I have to hold it tight while I was tested it without fixed into the ball, because the rotating force is quite powerful. Besides, there are some grease on the gear though…which made my hand sticky.

    Dscn0024

    13 ALL PARTS
    In this picture, you can see all parts inside the ball, including batteries, fixers, screws, speaker, PCB, motor, buttons, electronic cords, and the hard cover.  I found the structure is not so complex as I thought, especially the motor part.  And I like the way the maker codes the cord by color, which is easy to understand and recognize. This toy is a simple design with a lot of fun with attractive look and feel.

    +  What would you’d like get out of this class, if you have an idea.
    I would like to combine my thesis idea of ‘distance’ with my final project of this class.
    And last semester, I planed to do a distance sensing duck that always keeps certain distance with people. If it makes sense, I would like to make it real.
