The first experiment "fish camera" has come to an end -
http://www.looduskalender.ee/en/node/21749 The camera went off already some time during the day.
According to the article, the difference between the water temperature and the air temperature has become to great and there is danger that the camera aquarium may break from the difference.
It was interesting to watch fish under water, what they do, what is going on around and who all is passing in camera view. I personally would have been curious how the bottom looks once ice covers the stream on top.
Thanks to the inventors and clever minds in Estonia! You are always good for a surprise! Good luck for the next experiments!
