Hello all!
I would like to give you an update on the project. For a little over a year now, the G1X has been recording the sunrise and sunset timelapse. This means that it has now shot up to 540'000 images.
In the last months I was able to record all timelapses without dropouts, because the script is able to detect if the camera crashed and if so, to restart the camera. This has worked quite well.
This means that the camera still moves the lens in and out when rebooted, but I think the 30 reboots in the last 6 months shouldn't be too much wear and tear.
The temperatures inside the camera are manageable and reasonable: In winter, when the sun shines directly on the sensor, the temperatures are lower thanks to cold ambient temperature (max. about 40°C sensor temperature, usually in the range of 15°C to 35°C) than now in summer, when the sun does not shine on the sensor but heats up the roof (about 50°C sensor temperature and 30°C ambient temperature). I thought about sticking a heat sink on the back of the camera. But since the camera heats up only slightly on the outside, that makes little sense from my point of view.
Sound/music was also added to the timelapse. I recorded my brother playing some songs on the Styrian harmonica, a kind of diatonic button accordion that plays an integral part in alpine folk music.
