With a Raspberry Pi, a camera, and a bit of Python, you can build your own <strong>barcode-powered library catalog<\/strong> \u2014 scan a book, auto-fetch its title and author, log it in a database, and manage everything from a clean web interface.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">It&#8217;s perfect for book lovers, tool hoarders,
