Camera modified Technika 340.
Photo about every 15 minuites run at 8 F.P.S. in Windows movie maker. The video runs from 1st April to 21st April 2011.
Music is by Enya, A day without rain

At the start of the video the flower buds show circumnutation movement rotating about every 5 hours both at night and the day. Some are going clockwise and some anticlockwise. The movement was greatly reduced after the flowers open.

The camera control electronics consist of 1/2 of a 556 timer running at a high frequecy which is then reduced to 15 minuites by a 4020. The other half of the 556 operates the reed relay which fires the shutter. The camera is powered from a 5 volt supply reduced to 2.9 volts via 3 silicon diodes. The camera lens looks though the regulater heat sink to prevent dew on the lens. The rain cover for the camera is a plastic milk carton!
