well, i just built only the transmiter and connected it to my motherboard. but there appars no IR icon or such. checked device manager. it says a built-in IR device detected. i also took my digital camera and saw the led through the viewfinder-yes it was blinking occasionally, but without any reason! can u tell me why?
oh, i thought of transmitting files from my pc to my mobile. but nokia pc suite would first detect the phone using a receiver, then transmit files. can u instruct me as to how to make the receiver and combine it with the transmitter? i fear to experiment and damage the motherboard.
i wont use 1N4148, as it would be affected even by visible light. maybe using a voltage regulator with Vishay HS0038, with some capacitors and resistors?
