Project is kinda hidden in the basement at the moment. Had some problems with powering (but probably due to my lack of knowledge) and the IR-controler had some difficulties in bright sunlight (=huge IR source). Since the IR-beam was just a kit, it's kinda hard to put a pot meter in it for sensitivity adjustment.
So that's the status at the moment. For my camera I made remote with laser beam and I think it would be easy to fit it into this project.
