Zai’s Halloween Linguini Costume

Happy Halloween!

“Ratatouille” is a beloved animated film that many people grew up with, and dressing up as Linguini can be a nostalgic and heartwarming choice for movie fans. I witnessed that in the parade as people jumped in to take pictures!

It also fell into place when Jin came along to be my +1 for this costume duo. The ecstatic smiles and just gleams we received at the parade was not less of a compliment.

My intention with the LEDs was to create a lightbox to highlight ‘Remy’ character. As its Halloween, I also wanted to switch it up and make ‘remy pull the wrong nerve’ (evil)

How I made it

  • Materials: Parchment paper, velcro, acrylic band + sheet (lazercut mouse) , wire
  • Focussing on creating the most optimal lightbox, that could cast the perfect shadow, I began working on creating a study paper hat that would carry the weight of the batteries, past materials


#include <Adafruit_NeoPixel.h>

#define LED_PIN 1 // Define the Gemma’s data pin to which the LED strip is connected.

#define BUTTON_PIN 2 // Define the pin where the button is connected.

#define NUM_LEDS 30 // Change this to the number of LEDs in your strip.

Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUM_LEDS, LED_PIN, NEO_GRB + NEO_KHZ800);

bool buttonPressed = false;

bool isRed = true; // Start with red color

void setup() {

strip.begin();; // Initialize all pixels to ‘off’

pinMode(BUTTON_PIN, INPUT_PULLUP); // Enable the internal pull-up resistor for the button pin


void loop() {

if (digitalRead(BUTTON_PIN) == LOW) {

// Button is pressed

if (!buttonPressed) {

// If the button was just pressed, toggle between red and yellow

buttonPressed = true;

isRed = !isRed;

if (isRed) {


} else {




} else {

buttonPressed = false; // Reset the buttonPressed flag



void setRed() {

for (int i = 0; i < strip.numPixels(); i++) {

strip.setPixelColor(i, strip.Color(255, 0, 0)); // Red



void setYellow() {

for (int i = 0; i < strip.numPixels(); i++) {

strip.setPixelColor(i, strip.Color(200, 100, 50)); // Yellow



Things I would like to do differently

  • Solder better and effectively us the heat-shrinking tube
  • Find a better way to cast a shadow. Maybe?
