Several times since the foundation of the FabLab Yucatán I worked with kids from all the ages teaching electronics, robotics, digital fabrication and most of all implementing the workshops of the FabLat Kids Network, in these I saw a pedagogical base besides covering different themes of the fablab, but my concern was always that for example of 10 children only 5 or 6 correctly captured the workshop and these children have lacked attention and always anticipated the exercise.

_The first idea...

The project is a "dis / order" where through the tools of digital manufacture and parametric design we can obtain 4 different electronic modules that are interlaced to form a total of 16 pieces that react to being united forming a specific circuit, each electronic element (MDF in laser cut, 3D printing PLA, acrylic laser cut, Triplay CNC) and output (LED, vibrator, buzzer, battery), corresponding to the 4 main areas of the brain (motor, Visual, auditory and sensory) depending on the module.

_The project:

What will it do?

Based on digital fabrication, electronics and ADHD educations for kids DIS/ORDER consists of a tool to teach the basic principles of electronica, 3D and IoT design through the creation of a circuit snapping the 4 modules with different textures and colors that when connected react between them that through an interface for controlling the outputs.

Who's done what beforehand?

Project references for the electronics

  • LittleBits
  • LEGO Brick Brites
  • Project references for educational approach

  • Changing Education Paradigms - ADHD, Creativity and the Education System (Sir Ken Robinson)
  • Tangle therapy
  • What materials and components will be required?

    For the physical forms:

  • PLA for 3D printing the 2 side-molds
  • Silicon and resins for the cast
  • For the electronics:

  • Copper PCB for milling
  • 2 ATtiny45 for each module
  • ESP8266 for the WIFI module
  • Coin cell battery 3.3v
  • 1 LED RGB
  • 1 Minispeaker
  • FTDI header
  • 4 4x4 header
  • 10k 1k 499ohms Resistors
  • 1uF 10uF Capacitors
  • 3.3v voltage regulator
  • FTDI cable for programming
  • Where will they come from?

    From the FabInventory and Digikey.

    How much will it cost?

  • Full list of components and prices
  • This list present how much it cost each module with their electronic components and the extra materials present all the others materials (this have asterisk because you can cast more than 4 modules with that amount of material).

    What parts and systems will be made?

    All the partes of each module included the case, the electronics,the code and the web interface.

    What processes will be used?

    Processes :

  • 3D design and 3D printing for the 2 sides molds.
  • Molding and casting for the pieces.
  • Electronics design and production for the each board.
  • Programming, wireless communication and interface for the digital plataform.
  • What tasks need to be completed?

  • Printing the molds
  • Mold and cast the pieces
  • Mill the boards and communicate each module through the spring loaded pins.
  • Program the interface and edit the webpage.
  • What questions need to be answered?

  • How to create the own IP of the wifi module.
  • Mold and cast the pieces
  • Mill the boards
  • Program the interface and edit the webpage.
  • What is the schedule?

    WEEK 01 31MAY-2JUN

  • Finish the boards and communicate all.
  • WEEK 02 5JUN-9JUN

  • 3D print the molds.
  • Cast parts.
  • Programm all electronics and make it works correct.
  • Personalize webpage for interface.
  • WEEK 03 12JUN-14JUN

  • Final presentation video.
  • Details about documentation.
  • How will it be evaluated?

    I think that from the conception of the project and going through each of the assigments, it has taken shape and I have learned how to focus on what I learned to be able to develop it. When I started the FabAcademy I had no idea how the part of the project was going to work electronics and programming, as well as how to create parts and interface.
