BrailleBox is a refreshable braille display using Android Things. Using a news article API, BrailleBox will make a request and read back the current trending news to the user in the form of braille - as a proof of concept, this shows that any form of data could be retrieved and read to the user - allowing content to become more accessible to everyone.
Check out this blog post to read more about the project and learn to build your own.
