Hi all,
I hope this is the correct area. I'm not sure as it is a strange request.
I'm building a custom project that is going to be remote running from a laptop. There will be no AC power, only the power of the laptop battery.
I need a loud alarm or siren that I can trigger from the laptop. I am familiar with programming and have already written the software I need. the problem is the built in amp/speakers doesn't get anywhere near loud enough. Can anyone think of something clever I can either plug into the sound out jack or even a usb based device that would be a loud alarm?
I thought of perhaps a speaker powered by a simple 9v battery amp (I think they are called C Moy?) but I wasn't sure how loud that would get. I'd like to be able to hear the alarm from a couple hundred feet away. But that is in a quiet area. I also thought of some sort of horrible loud piezo buzzer, but wasn't sure how to drive that.
Let me know any thoughts suggestions! Thanks all!
