What is Nostr?
I am an engineer that makes open source hardware projects in my spare time. You can find my github with all the projects at:

https://www.github.com/profdc9

Please let me know if you're interested in them, I wish to promote them because I hope the projects will be both practically useful and help engineering education. They use very simple "jellybean" parts mostly so they should be able to be constructed by most hobbyists with access to electronics parts stores.
