Ever wished you could easily share your collection of PDFs, DIY books, or magazines? Adafruit has a guide to turn a Raspberry Pi Zero into a little digital free library you can take with you anywhere.
This project essentially turns a Raspberry Pi into a Wi-Fi hotspot and small web server that hosts your books or magazines. When you want to share your library collection with someone, just plug the Pi in and they will be able to connect to its Wi-Fi network. Sure, there are tons of simpler ways to do this, like a public Dropbox folder, but this is way more fun.
It's especially clever as a means for self-publishers to share their books for free. It doesn't have to be just for books either, music files, art, games, or whatever else you're making would work just as well. Just make sure you use this for good instead of distributing someone else's stuff.
