Final Project¶

Overview¶

My final project idea is designed to help teach the culture of my home island, Guam, to those who do not know as much about it.

The project consists of a board (roughly 2’ x 1.5’) that has an OLED screen along with a map of Guam. To accompany the board, there will also be a piece similar to a chess pawn.

The island of Guam will have sensors at cultural landmarks, and when the pawn piece is placed on those sensors, there will be a two-way response. The sensor on the board will control the screen and cause it to show an image or images related to the location and providing information. The pawn-like piece will also have a sensor that, when triggered, will output an audio recording to go along with the information on the board.

Bill of Materials¶

List of Tasks to be Completed¶

Electronics:

• Make main board for Xiao RP2040
• Connect and program OLED screen to display certain images
• Design and assemble board for sensors
• Program sensors and test them through acrylic
• Connect the electronics together

Board:

• Make a vector file containing designs for the wooden container
• Cut the file using the large CNC machine and sand pieces
• Cut acrylic shape of Guam
• Mold rubber feet for the board

Assembly:

• Fix screen and acrylic to top wood piece
• Place sides onto container
• Affix RP2040 board and sensor board
• Make hole for power source in one side and assemble all wood pieces

Gantt Chart for Tasks¶

Quick Sketch of Design¶

Marker Design in Fusion 360¶

This is the rough design of the marker that will be placed on the board. It will likely be a hollow piece to store electronic components, and I plan to 3D print this.

Cuttle Board Design¶

I plan to use a ShopBot or some other CNC machine to cut the board using this Cuttle file. I may need to convert the vector design to a path before I can cut it out.

Parametric Sensor Holder Model¶

Note: This design will likely be scrapped.

I designed a button holder that could scale parametrically with the width and height of my desired magnet. Since I plan for it to be rectangular but I am unsure of the exact dimensions that I want, I felt like it would be best to make it rectangular. I also added some notches that could snap into the board once the button is placed inside of its respective slot.
