Hello engineers, I learned the theory of transistors and that is all fine and dandy but in order to learn how to drive a car, you must drive a car, you cannot learn how to drive from books. So i googled some small transistor beginner projects and I stumbled onto a fun LED flasher. [PLAIN]http://pokit.org/get/4b011e2f5e0a6490eef4bf0e13e8edd3.jpg [Broken] Now, I assembled this and wouldn't you know it flashes ^^. But, yea I am not a kid with legos, I want to understand this circuit. Original site provided a slim explanation. I am getting confused here, why is capacitor's cathode connected to positive voltage supply? Can anybody help me understand what is going on, in detail? I think this will help me understand in general dynamic RC circuits like this. I think this is a good start. I want to see those holes, electrons in action, what charges first, what conducts etc.
