well i need a device to make an annoing sound, for more things to ue on:
i sellp very well, and even if o modified a clocl to sound 10 times louder ir is not strong enough to wake me up, so i want to make a douns generator with a very announg sound, wich will make noise for 1 minute.
the other thing i need it for is to prevent people and animals to going in a room, to sound when someone comes there.(i got the triggering device) but the first use is more important.
now, what i thought of is a high frequency sound, with great power, but having a strong sound will wake up people from other rooms, so i want something annoing but not so loud.
i wait for your ideas, on this circuit, and also for other ideas to wake up a sleepy persson.
thanks in advance.
