If you are a Harry Potter fan, you might remember that one of the movies showed an Isle of Lewis chess set whose pieces moved in response to a player’s voice commands. This feat has been oft replicated by hackers and [amoyag00] has a version that brings together a Raspberry Pi, Arduino, Android, and the Stockfish chess engine in case you want to play by yourself. You can see a video of the game, below.

Interestingly, the system uses Marlin — the 3D printing software — to handle motion using the Arduino. We suppose moving chess pieces over a path isn’t much different than moving a print head. It is certainly a novel use of GCode.

There are a lot of pieces integrated to make this work. There is a Bluetooth connection between the Android and Pi. We saw code in Java, Python, C++, at least. We were sad to read that the team that built it can’t modify it anymore as it was a school project and the parts have been recycled for a new class of students. On the other hand, maybe someone else will make a copy and extend it further.

We are always surprised we haven’t seen more Harry Potter paraphernalia. There was the magic wand at this year’s Superconference.¬†We also liked the Mad Eye Moody. There have been others, of course, but not as many as you’d think given the franchise’s popularity.
