Fox Spirit

My costume consists a skirt, a fox mask and a fan with Neo pixel lights.

Progress

The first three pictures are the ideas about the outfit and how the lights are set up. And the two on the bottom are the references.

Diagram

In the end of the process, I attached the Neo pixel to a traditional Chinese fan to show a beauty of Chinese culture.

Materials and Tools Used

Fabric/ Paper/ Arduino software/ Soldering Station/ Silicone wire/ Neo Pixel

Reflection

The whole process is challenging but really fun. I really like that we have this opportunity to make a halloween costume. This is the first time I went to a parade, and it is amazing. I first settled down with the outfit idea, and started to make a circuit, then put the circuit onto the costume. My costume is pretty comfortable to wear, and I realized the more LED you have on your costume, the greater attention you will get from the audience. I am glad that we elaborate LED into our costume.

Code

// A basic everyday NeoPixel strip test program.

// NEOPIXEL BEST PRACTICES for most reliable operation:
// – Add 1000 uF CAPACITOR between NeoPixel strip’s + and – connections.
// – MINIMIZE WIRING LENGTH between microcontroller board and first pixel.
// – NeoPixel strip’s DATA-IN should pass through a 300-500 OHM RESISTOR.
// – AVOID connecting NeoPixels on a LIVE CIRCUIT. If you must, ALWAYS
// connect GROUND (-) first, then +, then data.
// – When using a 3.3V microcontroller with a 5V-powered NeoPixel strip,
// a LOGIC-LEVEL CONVERTER on the data line is STRONGLY RECOMMENDED.
// (Skipping these may work OK on your workbench but can fail in the field)

// Which pin on the Arduino is connected to the NeoPixels?
// On a Trinket or Gemma we suggest changing this to 1:

define LED_PIN 1

// How many NeoPixels are attached to the Arduino?

define LED_COUNT 60

// Declare our NeoPixel strip object:
Adafruit_NeoPixel strip(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);
// Argument 1 = Number of pixels in NeoPixel strip
// Argument 2 = Arduino pin number (most are valid)
// Argument 3 = Pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic ‘v1’ (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
// NEO_RGBW Pixels are wired for RGBW bitstream (NeoPixel RGBW products)
