Project Status: Prototype Phase / integrated into Bomb Prop

A simpler version of the Bomb Prop. The Simple Bomb Prop has 6 exposed wires that can be cut or disconnected. 2 wires disarm the bomb, 2 wires do nothing at all, and 2 wires "detonate" the bomb. The result for each wire is shuffled when the prop is activated, so the wires are never in the same order. This device has no keypad or LCD. When disarmed, a green LED is lit, when detonated, a siren sounds for 5 seconds, and a red LED is lit. 5 smaller red LEDs indicate the state of the timer. 1 lit = 9 minutes remaining. 2 lit = 7 minutes remaining, 3 lit = 5 minutes remaining, 4 lit = 3 minutes remaining, 5 lit = 2 minutes remaining, 4 lit & 1 blinking = less than 59 seconds remaining, 5 blinking = less than 30 seconds remaining.
