Yeah... send me the circuit to convert a pen drive into a TV too please. I don't need anything special 50 inch HD with LED backlight and 3D compatible will do. Can I run it on watch batteries to keep the size small. Oh, I nearly forgot, just one more requirement, it has to roll up so it fits in my short pocket.
Get real 'lakshmipathi.vemula' read the USB specifications, read the pen drive specifications and find out how it works and you will see why it isn't possible. It isn't considered polite to say 'send the required ckt diagram' either. There are many of us out here who are more than willing to assist you learn or design things but we are not a charity. We are unpaid volunteers, never think we will undertake major design work to satisfy your demands.
