Well the kids have lost interest in Raspberry Pi Python programming for now, but look who’s still at it! The jankyiest of Lego stop motions.
Here was the code I tossed together to make the gif above:
#!/usr/bin/env python2
import os
import time
import shutil
import datetime
import tempfile
import pygame.camera
import pygame.image
import RPi.GPIO as GPIO
save_dir = '/usr/share/nginx/www'
GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)
GPIO.cleanup()
GPIO.setup(17, GPIO.IN)
pygame.camera.init()
camera = pygame.camera.Camera('/dev/video0')
def make_picture(filename):
raw_input('Ready for picture? ')
camera.start()
image = camera.get_image()
pygame.image.save(image, filename)
camera.stop()
def make_gif(frames=5):
print 'Making you a gif using %s frames, get ready!' % frames
time.sleep(0.5)
dir = tempfile.mkdtemp()
for i in range(frames):
print 'Taking picture!'
make_picture('%s/%s.jpg' % (dir, i))
time.sleep(3)
print 'Converting images to gif, please wait...'
os.system('convert -delay 20 %s/*.jpg %s/animated.gif' % (dir, dir))
filename = '%s.gif' % datetime.datetime.now().isoformat()
shutil.move('%s/animated.gif' % dir, '%s/%s' % (save_dir, filename))
shutil.rmtree(dir)
print 'Complete!'
while True:
if GPIO.input(17):
make_gif()
GPIO.cleanup()
And a picture of the rig:
