From the project
A chess board that sees every piece, lights every move, and thinks alongside you
With the power of electro-magnetism this master board is capable of reading every move that the players are making. The powerfull chip with the built in machine gives us the power of a ~2000 ELO player that computes the best moves within 2 seconds and finally the built in RGB LED matrix sends light signals towards the player with the best move suggestions for you to beat every opponent.
