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)

Last year, I made a talking witch (also using a Raspberry Pi). And I also have plenty of pumpkins: Baby Yoda, the Balrog, Predator, Gremlins, …
