This DIY Chess Board Lets You Play Against a Machine on a Real Board
You can play chess against a machine on almost any computer, but it is nowhere near as much fun as playing with real pieces. If you want to build a robot to play against itself, Maxim is demonstrating a board powered by a Raspberry Pi.
The idea here is pretty simple and works similar to something like a Revelation or Mephisto checkerboard . The computer runs the open source Stockfish chess engine. A magnet is attached to each piece. When you move a piece, the computer responds to tell you where to move your opponent’s piece (sorry, it can’t magically move the piece on its own). While the demo video demonstrates a Raspberry Pi and Arduino combination that is no longer needed, the new version of the Arduino manual is completely absent. Now you just need a Raspberry Pi, a reed switch, a set of LEDs, a small screen, a few smaller components, and your own chessboard.
This is not an easy project anyway, but if you are a chess player who prefers real pieces and opponents with artificial intelligence, it will be worth it. You will find a guide to making it at the link below.
