8 Eyes

He he he .. this kind of thing was one of my favourite oscillator applications in analogue electronics back in my teens. You'd set up an oscillator that made a beep with an unstable circuit so the frequency changed a little every time, then another slightly random oscillator to trigger it at intervals of about thirty minutes to an hour. There is nothing so annoying as a random beep that you don't what's making it. I've seen people unplug everything electric and change the smoke detector batteries several times trying to get rid of it.

Ahhhhhhhhhhhhhhhhhhhhhhh!!! So many bodies to hide while I figure out what's beeping.
