I have two small kids who love coloring and like most kids, they like to color a wide variety of pictures at a breakneck pace. Which means, asking mom and dad or anyone who will listen to print them some coloring pages - all of the time. And depending who they get to do their bidding, the sites chosen to download pages from may not be the most trustworthy....
Now they just ask Alexa who tells the Raspberry PI to send a random coloring page to the printer. They chose to call this skill 'em', I have no idea why.
** All of the install instructions for the Amazon & Pi pieces of the project are in the git repo. **
For the pages, I used python to download a set of safe files and stored them locally on the Pi. I haven't included the python here but can recommend looking into BeautifulSoup if you are interested in this approach. If not you can manually download a bunch of files and drop them in folder within your project directory.
Don't forget to order more ink & paper!
