I decided to update the shopping list code. Instead of downloading the shopping list every so often in a seperate python file I just downloaded it in the same file.
I also added a second button, which prints a random list.
AND I've updated it all to Python3!
Here's the updated code. I've hidden the URL to my website - you don't want my shopping list!
This is what the JSON looks like from the website:
I created a clear acryllic box for the printer and buttons to stay in.
Here are the laser cut files for the printer and 2 mini arcade buttons
The printer now runs on the same power supply and Raspberry Pi as the stair lights.
