I Made Chess 2.0

The creator of "Real Time Chess" shows how he built a physical electronic chessboard with no concept of turns, where pieces move whenever players can. The video covers the game rules he changed and the hardware and software engineering behind the board.

HN people kept submitting it as a fun hardware build that rethinks a very old game by removing turns.

“My video on it probably does a better job of explaining it than the github so I'd recommend checking that out”
