  Box Design

  • Objective: Create a physical enclosure to house all electronic and mechanical components.
  • Steps:
    • 3D Design: Use 3D design software (such as TinkerCAD or Fusion 360) to model the box.
    • 3D Printing: If possible, use a 3D printer to create the enclosure or purchase a standard case compatible with the electronic components.
    • Cutouts: Add slots for the microphone, speakers, buttons, LCD screen, and thermal printer.

  Electronic Hardware

  • Objective: Select the necessary electronic components for building the connected box.
  • Required Components:
    • Microcontroller (e.g., Raspberry Pi or Arduino with Wi-Fi module): The brain of the device, responsible for managing inputs and outputs (microphone, speaker, screen, buttons).
    • Push Buttons: To allow the user to validate the excuse or choose between voice playback and printing.
    • LCD Screen: To display the generated excuses. A 16x2 LCD screen or an OLED display is recommended.
    • Thermal Printer: A small thermal printer, like those used for printing receipts, will handle excuse printing.
    • Power Supply: Either a rechargeable battery or an AC adapter.
    • Mounting Plates & Wiring: Wires to connect all components, along with a mounting plate to organize them.

  Hardware Assembly

  • Component Assembly:
    • Fixing Components in the Enclosure: The microphone, speaker, buttons, and screen must be secured in their designated slots within the printed or purchased case.
    • Connecting Components: Use wires to connect each component to the microcontroller. The Wi-Fi module or card must be connected to the internet.
  • Wiring Check: Ensure all electrical connections are correct and that all components function properly.
