Great work on this project!
I’m envious that you have available data on your public transport! Where I live they’re still working on an API that has been advertised as “available soon” for multiple years :(
I have a very similar project with a pi zero and waveshare e-paper display! I’m showing the weather, a countdown to events I’m looking forward to and a virtual pet that changes pose every so often. Here is an older picture of it:
Wow, good tip, I didn’t know of that. Sadly, where I live this is still ‘in preparation’. But I’ll keep looking in case this happens before my cities API! Thank you!
