Today I made a digital zombie circuit. At first I made a flashing LED circuit with a 555 timer, but then I thought about adding a smaller capacitor and switching the LED out with a small 8 ohm speaker. When I turned it on, I heard a buzzing sound. Then, to amplify the sound, I added two transistors to amplify the 555 timer's output. The sound was much louder. I also call it the Ghost Communicator because ghosts sometimes speak through white noise. I call it the Digital Zombie because it sounds like a computer that was turned into a zombie.
