Make a Simple Machine Gun Sound Effect Generator Circuit

Posted on Feb 5, 2014

An impressive little machine gun sound effect generator circuit is discussed here. Once built can be integrated with any audio amplifier to experience a roaring bullet studded war like simulation. A small hobby project which can be tried by all electronic enthusiasts will generate interesting machine gun sound effect over the connected loudspeaker

, quite imitating the sound effects of the many action packed computer war games. We all have played TV/computer games at some period of our life and know how exciting it feels to hear the different audio effects accompanied with such games especially the ones which involve heavy arms and actions. Boys truly love playing action games like delta force, hitman and appreciate not only the visuals but also the produced machine gun sound effect. Although our world has gone hi-tech and it requires just a single small chip to generate many intriguing audio sounds but building one such circuit using discrete components can be quite amusing too. Especially the electronic enthusiasts will love making an electronic machine gun sound generator using few CMOS ICs and some other passive components. Here we discuss one simple machine gun sound effect generator circuit using three 74LS04 and just a handful of resistors. The IC 74LS04 is basically a hex NOT gate IC. It consists of six NOT gates or inverters in one package. Each gate has two terminals one input and one output. As the name suggests the logic generated at the output of the gates will be exactly the opposite of the received input level. The pulses produced at the output of each section have their own distinct push pull ratios. These are integrated together and superimposed simulating exact machine gun shots. Looking carefully, the circuit reveals that the six inverters from...

I spent 2-1/2 days building this project and am very disappointed with the output sound. Each of the 9 total oscillators in the three ic's have outputs. I believe there is some errors in the cap or resistance values in this schematic. If someone has built this project and has good results, I would like to hear from you.
