The display shows a real-time view of the incoming trains for either New York or Boston subway stops. It's powered by five 32x32 dot matrix LED displays daisy-chained and controlled by a Rasbperry Pi. The MTA and MBTA fonts were faithfully re-created pixel-by-pixel from hundreds of reference pictures, along with the specific copy and timing of announcements. The final product is an exact and functional replica of both the MTA's and MBTA's arrival boards. The display can also show currently playing songs and album art from Spotify.
