Final Project¶

This week I worked on defining my final project idea. for my final project i wanted to do something that can reflect my personality and something that i like. so that is why i worked on Light Fixture because i am a gamer and i play video games almost everyday and every gamer setup must have RBG lights to make his/her setup more cooler. Light Fixture is something that is simple but cool and in my opinion when you walk in any room the first thing that will catch your eye is the RBG light that makes the room more awesome and makes you whish to have something like it so that is way i choose this idea as my project.

Research¶

For research, i searched for multiple design ideas for light fixture and LED panels to get an inspiration for my project structure, i didn’t have an idea for the design at first but after searching and looking through different light fixtures, i got inspired by a different thing entirely which is the Wyndham Hotel. The swirly and tilted design of the hotel was something beautiful which i admired and appreciated.

Fusion Slicer¶

for the design of the structure, it was easy to do because Fusion Slicer pretty much did every thing for me, i just made the shape which like a cylinder and gave it some tilting or swirling and the program did every thing from slicing to assembling instruction.

Assembly¶

making the structure of the project i used 3mm MDF wood which is comprised wood which will provide a strong and solid structure. there are 20 pieces total, 10 vertical and 10 horizontal pieces. plus, Fusion Slicer marked each piece in the assembling instruction as i mentioned above which was very helpful and super easy to assemble. to cut the pieces, i used laser cutter which was the fasted and best way to handle 3mm MDF wood.

here is a video for vertical pieces.

here is a video for horizontal pieces.

as i said the assembly part was very easy, it was like putting Lego part on top of each other. below you will see the assembling steps from each direction.

then i putted inside of the structure a pole which the LED light will wrap around it and gives stability to the lights.

finally, this is a turn around video after assembling.

after finishing the assembly, the color of the structure was not good and had some burned areas due to the laser cutter so i decided to painted all MATT Black which will emphasis more on the colors coming form the LED and makes the structure looks cool in the dark.

LED light , microcontroller and coding¶

the LED lights was provided by FABLAB so i used different codes to test if the lights is working and i learned that there is different modes for the lights to work so i wanted to decide what to use. the colors i used are the main colors Red, Green, Blue and my favorite color purple. also, the lights will be covered by tracing paper that will hide the lights and wiring plus making the lights pleasant to look at.

after testing the light, i wanted to add another feature for the light fixture so while researching in week 5 about the microcontroller i learned that there is a gesture sensor so i upgraded the idea to make it an interactive light fixture which will give the ability to change the lights color with different hand gestures. there are 4 gestures in total(up, down, left and right) each specific direction will give you a different color when you swipe your hand on it.

this is the gesture code.

#include "Adafruit_APDS9960.h"
#include <SPI.h>

#include <Wire.h>
#include <PDM.h>
#include <SoftwareSerial.h>

Adafruit_APDS9960 apds;

// the setup function runs once when you press reset or power the board
void setup() {
  Serial.begin(115200);

  if(!apds.begin()){
    Serial.println("failed to initialize device! Please check your wiring.");
  }
  else Serial.println("Device initialized!");

  //gesture mode will be entered once proximity mode senses something close
  apds.enableProximity(true);
  apds.enableGesture(true);
}

// the loop function runs over and over again forever
void loop() {
  //read a gesture from the device
    uint8_t gesture = apds.readGesture();
    if(gesture == APDS9960_DOWN) Serial.println("v");
    if(gesture == APDS9960_UP) Serial.println("^");
    if(gesture == APDS9960_LEFT) Serial.println("<");
    if(gesture == APDS9960_RIGHT) Serial.println(">");
}

the final step was to program the microcontroller gesture sensor and the LED light together. this is the code.
