nostr:npub10ae605fgpw08r8d2u7u65wu82n5n02gzv4wef797z5dk7g3w8smq7xnlyc I currently only have one and don't plan on building many more. Still it is open source and I don't want others to have the same disappointing experience as I do :D
The whole board is battery powered, I probably can use the main battery for that task
