My Final Project
This is where I will start defining my final project idea and its development process.
Early steps
My little brother loves a TV show where two teams play something similar to charades. Instead of acting and guessing a word, they need to guess the name of a movie or a song. With each turn, a different member throws a big fluffy die, and depending on the number on the top, there are specific rules that need to be followed to act out the phrase.They only have 20 seconds to act and guess.
Last Christmas I wanted to give my brother a die as a present, but there weren’t many options online. So, I came up with the idea to make a die that can detect the die´s position, with a Bluetooth-connected card box that opens to reveal the film/song name according to the number in which the die landed. I can also make a timer with 8-segment displays that can be started with a button and with a small speaker playing an alarm when the time elapses.
Here is the first sketch I made for this project.
The plan is to make a Dice that can identify and communicate via Bluetooth the number on top to a 3D-printed box where the movies and song cards will be contained. Depending on the number on the die, a different compartment will open. The difficulty will vary. Small numbers will reveal cards with short and easy names, while higher numbers will contain larger names or harder words to act.
The “cube” faces will be made of Medium-Density Fiberboard. Inside, it will have an accelerometer to detect the landing face. I´ll be using a XIAOnRF52840 sense with a built-in accelerometer. I am planning to make soft-rounded corners for the cube so it can bounce once it hits the ground. As decoration, I´ll be putting LEDs on the die´s faces to run a sequence for each number.
I decided to design a mechanism to open the different compartments according to each categories. I used Procreate to sketch my initial ideas:
The box will have a Bluetooth module to communicate with the die. I might add a small speaker to play the alarm sound when the time is up. The box will have a charging port and a battery to make it portable.
