Pennywise Pumpkin

This talking Pennywise pumpkin will scare the hell out of you!

For the pumpkin design, I followed the tutorial by PumpkinFreak. His Pennywise pumpkin looks much better than mine, but I’m still very happy with my result.

As a bonus, I’ve added special light & sound effects: The pumpkin contains a speaker and led lights (Adafruit LED sequins). I have a Raspberry Pi that controls the led & speakers, but I kept it outside of the pumpkin, so that it’s not impacted by the humidity.

The pumpkin normally glows with a yellow light, but when Pennywise speaks it turns red: “Hiya Georgie! Do you wanna balloon?”. It certainly scared a number of visitors.

Check the video to see it in action:

Coding

I’ve used microPython for the Raspberry Pi coding

#!/usr/bin/env python3
import pygame
import random
import time
from gpiozero import LED
from aiy.pins import (PIN_A,PIN_B,PIN_C,PIN_D)

#initialize sound
pygame.mixer.pre_init(frequency=44100, size=-16, channels=2, buffer=4096)
pygame.mixer.init()
pygame.mixer.music.set_volume(0.8)

#initialize other things
led_a = LED(PIN_A)
led_b = LED(PIN_B)

#sound list
_sounds = ['Balloon.mp3','Going.mp3','Hiya-Georgie.mp3','Laughing-1.mp3','Laughing-2.mp3','Meet-Pennywise.mp3','Pennywise.mp3']

#play random sound
while True:
    led_a.off()
    led_b.on()
    time.sleep(1)
    next_sound = random.choice(_sounds)
    pygame.mixer.music.load("/home/pi/Documents/Programs/Pennywise/Sounds/"+next_sound)
    pygame.mixer.music.play()
    while pygame.mixer.music.get_busy() == True:
        pass
    time.sleep(1)
    led_b.off()
    led_a.on()
    time.sleep(30)
