We built an Open Source, RFID based, WIFI enabled cassette-style recorder, powered by Elixir and the Nerves Framework. We call it the Looniebox, and it’s a wonderful way to share the old “fumble with scissors in the cassette to fix it” experience with kids. In this talk, we’ll discuss the work that went into creating the Looniebox, the journey learning hardware hacking and the Nerves Framework, and the love and joy we put into building it. And if the kids let me take it away from them, the Looniebox will also be demoed.
