Chess is a game that originated so long ago, we don’t have concrete information as to its origins. Rules have changed throughout history, and many continue to study and experiment with the game. [Yann Guidon] has a neighbour, [Bob], who is just one such enthusiast, and together, they built a working Trap Chess game.

What is trap chess, you may ask? It’s a variant of chess where pieces randomly fall into traps at the change of turns. This is easy to simulate in a digital game, but that wasn’t enough for [Bob]. Enlisting [Yann] for his electrical skills, the duo built a board with ten trapdoors built in. Whenever the timer is hit, there’s a chance a trapdoor can open, removing a piece from the game.

The build relies on a PIC16F818, an 8-bit microcontroller from Microchip. This helps interface between the timer and servos and generally runs the whole show. The board is built into a table, and we’re impressed by the fit and finish of the final product. From a distance, it’s difficult to notice anything is awry, and it would make a great prank when playing with an unsuspecting mark. Just make sure there’s no money on the table first.
