At the end of 2016 I created something I called Plastic Player — an NFC based analogue controller for digital music. It was a way to combine my love of digital music such as Spotify with the physical nature of analog inspired by vinyl records. People seemed to really like it, so much so that I would often get emails asking how can they can buy one? Taking something like this that I make for myself to a viable commercial product is a big ask and fairly complex.
So instead I decided to redesign it and then make it open source so that anyone could read the details, download the code and make their own version of the Plastic Player.
