Do you have an idea on how to keep the LDR on the led even though the camera is moving?

Well, I'm from OK, so tape is an obvious choice. :-) You could just use some long wires on the light sensor and tape it, or for a more permanent solution, maybe a clear glue on the face of the cell, then glue around the outside with something black to block light out. Black caulking would work. For the clear glue, use GOOP. It sticks to everything, is clear, and peels right off if you need to clean it off later.

Sorry, the abbreviation for the state of Oklahoma in the US. We're kinda rednecks down here. Well at least some of us are. ;-)

So "Well, I'm from OK, so tape is an obvious choice." is an insider joke, tell me what it is about

Back to topic: I like your ideas. But you are fishing in the dark and that is my fault. So I am going to create some light:

The camera is rotating and is taking photos to be combined in a time-lapse-movie. After that I take it from the retainer to connect it to my pc or to take some photos freehand. Then I want to put it in again.

When the photos are taken there is rapid movement being applied to the camera.

I thought about using a clamp, see picture, but I haven't managed to find out a suitable material yet. The problems arise because of the force being applied to the edges of the material(at the sharp angles of the clamp). I would have to subtly bend it over and over again which will sooner or later weaken the material to a critical degree.

Well, people in the Southern US states have a reputation of "repairing" (rigging) things with tape and wire, instead of really repairing them. :-)

Sounds like a cool project that you are working on. Will the camera rotate completly around? If so, how many rotations?

and when it fails . . . hence the term " it went haywire" . . . Look at how much tape gets used in NASCAR . . . BFH Big Friendly Hammer . . . CMCON = 7 turn off comparators, look at pp 68 of the data sheet try vrcon = 0 shuts vrcon down
