Build An Annoying Beeping Thing
I’m always up for a good practical joke, especially the kind that involves electronics and can drive people mad. Get your soldering guns out kids, this is a good one.
The Annoying Beeping Thing is a simple circuit board that is powered by a single 9-volt battery and outputs a high-pitched whining sound through a tiny speaker or piezo buzzer.
As you can see from the pictures above it’s hidden inside of a transformed but this thing is so tiny that you can practically hide it anywhere. Make sure you don’t let the joke run on too long as it might really get on someone’s nerve who might not think it’s all that funny. Check out the video after the break of it’s construction and to hear it in action.
