    I am new to this forum and am in desperate need of assistance.
    Google has not been very helpful and since forums are the best place to search for information I figured that you folks would be the ones to ask. I have asked at my local Radio Shack and they have NO idea........

    I am a prop builder and am currently building a replica M7 SOCOM submachine gun from the Halo video game franchise. For those familiar with the Halo story, this is the primary weapon of the ODST's.

    In any event, I would like to add sound to this weapon but I have a limited amount of space in the butt stock to work with.

    My question, given my extremely limited experience, is how to best go about this.

    I want the sound to be controlled by a switch, so every time I press the trigger, the trigger hits the switch and the sound will play. I would rather not use an iPod/mp3 setup due to charging issues, but I can if that process is explained.

    Any ideas that you folks have would be greatly appreciated and welcomed. I have never done anything like this before so please assume (correctly) that I will need things spelled out - lol.

    Thanks!
    ~ Ned

    Thanks for the reply Bob - but I am looking for something a bit more robust than a greeting card soundbox. I would prefer something that I could build and have be proprietary.

    I will look into the soundbox route though!

    How long a sound do you expect to play? A microcontroller with PWM or DAC output and enough code space to store in the sound in the flash memory would be a possibility. You would also need an audio amp. For longer sounds you could also use external ROM.

    I want, everytime I pull the trigger, for the sound the SMG makes to play. I would be using an audio file from the game.

    The area behind the trigger is not hollow so a wire would have to be threaded.
    I attached a picture of the space that I will have to work with. The upper portion will be entirely taken up by the buffer tube when the stock is retracted.

    If need be I can remove the bottom panel of the butt stock and use magnets to secure it in place - allowing access to any board that is in there.
    Thanks!

    That could definitely work!
    Ill check that out. I sent the seller a message asking for volume on that speaker and how long it will run for.
    That is exactly the setup I am looking for - but it has to be loud enough to be heard .
