Is anyone familiar with the electronics of Nikon SLR cameras? I have the following problem: In principle, most of these cameras (at least my F75 and D100) can be remotely controlled by an IR remote control. They have an IR sensor that responds to a IR signal sent from the remote control which has the same effect as pressing the shutter-release button. There is no data transmission other than this one signal, so it shouldn't be complicated. I don't want to use a remote control, but instead want to construct a system that shoots one photo automatically any few hours. First i asked Nikon about the trigger signal, but they just answered, they won't say. Then i tried it with square waves at an IR LED and any frequency, pulse width, duty cycle etc. The camera never responded. Then i wanted to buy a simple remote control (called ML-L3) just getting the answer that it is obsolete. Searching the interet also gave nothing useable. Now my question is: Does anyone know how this remote signal has to be? Or does anyone have the remote control and maybe could try it with a phototransistor connected to an oscilloscope. I'm especially interested to know whether it is just a continuous wave signal with specified frequency etc., or it is something more complicated like a digital serial bit-by-bit coding? Thank you very much!
