This is one of those projects every nerd loves to build :D
My first iteration back in lockdown [0] focused mainly on rain (I'm from the UK), but later versions used a colour e-ink, added a camera to change the background with a selfie and added train times from my local station, along with upcoming birthdays. Reminds me I need to try and write an update at some point!
