So one day my neighbour comes and asks for help. Why not ?
Imagine you play chess against your opponent. Sometimes one of your pieces falls into a trap that opens suddenly as you press the button of the timer.
Bob has built two chess boards with traps, operated by individual servomotors. Each chess pieces has a magnet, that is detected by reed sensors. My mission is to create the electronic board to control the whole thing... Uncontrollably.
