Hello all, I am starting to learn about electronics due to a project of mine. I need to make an alarm that when you pull a wire out or disconnect it then it sounds an alarm, basically like some would call a luggage alarm or a pull pin alarm. I need it to be compact and light but also loud, I need help with a proper schematic if anyone knows of one and the components.
I have been doing some research and I would like it as loud as this or louder if possible:
I don't need the tone change but is the 555IC and NPN transistor the best way to accomplish this or is there another setup that would give me that loud, constant frequency while being in a compact package. Thanks for all the help.
