Battle Stations! Battle Stations! Here's an adaptable noisemaker project to build for gameplay, a unique alarm, or even amateur film.
If you have ever watched a war film involving naval ships from around World War II onwards you have probably heard the sound effect used to send the crew to battle stations. Similar alarms are used when a submarine dives, or in damage control incidents.
It’s a harsh-sounding electromechanical buzzer sound, pulsing on and off. The sound itself varies wildly, both in tone, the length of the pulse of sound, and the gap between them.
Our build is adaptable in that you can set the characteristics yourself and experiment until you’re happy. With this circuit, you can change the sound so much that it will even sound like an aircraft cockpit warning sound, also a common trope in films.
We use a breadboard, two 555 timers, audio module, and a handful of common components.
