I was able to accomplish this by following: [https://github.com/llvllch/btcticker](https://github.com/llvllch/btcticker)
[It uses a raspberry pi and a little e-ink display like a kindle.](https://preview.redd.it/299ay2m4frt61.jpg?width=4032&format=pjpg&auto=webp&s=79b3bf7630678cd3bdaf9e383e433b9754c1f727)
It cycles among 4 coins I’m watching, gets it’s price info from Coingecko, and uses very little power due to the nature of the screen technology. I’m able to configure the amount of time it shows each coin, change the update frequency, etc.
I’m pretty happy with it so I wanted to share it with you.
Credit goes to llvllch for the project.
