Minecraft server
now the pi is a pi hole, tor snowflake proxy and uptime kuma server to monitor the real node hardware.
Run Batocera and play games while the node is syncing
Build a self regulating hydroponic garden. Grow some veggies :-)
I’d just run another node with the same wallet
Use it to run a USB-Miner.
