Great article, Keith.
I think your link to adafruit is malformed; it appears to be a relative link, missing the https:// protocol, so it comes up as a 404 in GitHub.
Hoping to clarify what seems to be a misunderstanding by nostr:npub1qny3tkh0acurzla8x3zy4nhrjz5zd8l9sy9jys09umwng00manysew95gx about how the Pi Zero hardware shapes the nostr:npub17tyke9lkgxd98ruyeul6wt3pj3s9uxzgp9hxu5tsenjmweue6sqq4y3mgl security model.
(see: nostr:npub10uthwp4ddc9w5adfuv69m8la4enkwma07fymuetmt93htcww6wgs55xdlq #320)
I'm not about drama, certainly not looking to increase it.
Please give this a read and hit me back w/any questions:
