LAPUTA: CASTLE IN THE SKY LOGO & ROBOT

Rewatching the Miyazaki/Studio Ghibli movies, I was keen to recreate some of the items from Laputa: Castle in the Sky…

Dola / Dōra Pirate Logo

Dola / Dōra Pirate LogoLooks great on a t-shirt…

Laputa Robot

I wanted to recreate the head of the garden robot, and wire it up to respond to messages on my network.

OnShape assets. Head = resin-printed + model paints; neck = laser-cut from 3mm-thick MDF.

Electronics

Laputa Robot circuitBoM: Raspberry Pi Pico W; red LED x 2; 330Ω resistor x 2.

Code

Extend my Raspberry Pi Pico W / Python / MQTT code by adding the following lines (near the top of that code):

import board
import digitalio
import random

led1 = digitalio.DigitalInOut(board.GP16)
led2 = digitalio.DigitalInOut(board.GP19)
led1.direction = digitalio.Direction.OUTPUT
led2.direction = digitalio.Direction.OUTPUT
led1.value = False
led2.value = False

def do_eyes():
	led1.value = False
	led2.value = False

	ss = 1/6 # seconds
	for ii in range(12): # for a total of 2-seconds
		if random.choice([True, False]):
			led1.value = not led1.value
		# end if
		if random.choice([True, False]):
			led2.value = not led2.value
		# end if
		time.sleep(ss)
	# end if

	led1.value = False
	led2.value = False
# end do_eyes()

def message(client, topic, message):
	do_eyes()
# end message()
