While it may seem disappointing that this Lego record player doesn’t actually play vinyl records, that’s actually not a bad thing. Its colour-coded record playback mechanism is much more awesome than standard record playing.
These player’s records are created using a program that codifies musical notes into patches of colour distributed in concentric circles. The program prints out a circular page that gets glued to an LP.
When you put it in the player, Lego Mindstorm cameras inside detect the spinning colours, playing back the encoded notes. All while a few Lego minifigs dance to the tune. If that’s not delightfully ingenious, I don’t know what is. [Rebrick]
