Built a Nerf Russian Roulette game

One chamber fires, the rest don’t, and if you’re the unlucky one the gun rats you out with a loud active buzzer. The core problem was detecting whether a dart actually left the barrel: tried a light sensor/emitter pair across the nozzle first, but alignment was a nightmare and I scrapped it after it kept false-triggering. Ended up wrapping bare wire around the inside of the nozzle and foiling the dart tip, when it passes through, it bridges the circuit and sends a signal. Finding a wire routing that stayed put, didn’t short against itself, but was still close enough to make contact took about two hours of fiddling. Next step is to add a electric shocker, which has more dramatic effect, but I am still figuring out the best way to do that without overcomplicating the handle.
