This project is a circuit that makes the annoying sound that an old TV makes when the volume is off. This project is great for annoying someone like a brother or sister, your friends or even your enemy.
Have you ever heard that ringing sound coming from an old TV? Well, that never happens anymore because TVs today use LEDs or other advanced technology. That old high-pitched whine came from the transformer that drove the cathode ray tube.
Even today when I hear that sound it sends a shiver down my spine, but I want to recreate that sound in this circuit.
