After lots of fiddling about I have finally got the Meadowcam working again. I have reprogrammed the controller although I don't think that was the main problem. I think the main problem was that the small cocktail stick being used as a strut to keep the camera turned on was affecting the dial. I have used a beefed up version made from a wooden skewer. Tests using a clock have been successful so far. I will continue to run it for a few more days. Before I take it back to install on the meadow I will make a set of replacement sticks to the same spec as the new one. I will also refrain from using the play function of the camera. I will use the Netbook to check images and avoid moving the strut at all.
