really nice. thank you for sharing all this. as soon as i find the time i will try it too. i have an unused pi waiting to be connected. btw: which post should I merit...

btw: a first question. i once had a core node running. but the pi was so slow and it wasent able to be up to date with the chain. do you have this problem too?
If you are talking about pi performance(not slow downloading speed) you can run raspberry in cli mode(without GUI). You can find it in raspi-config.
