Well I have a video of the head flash during the burst but I'm finding it a right pain to translate.
I can do frame by frame but determining if it's on or off is almost guesswork at some points, I thin because underneath the flashes the thing still pulses, so sometimes you aren't sure if it's on or off.
I don't think it will work. It demands sitting in camera debug mode, right? Debug mode to solve the puzzle? I don't think so.
