On Thursday afternoon I started a first test run for a long duration time lapse video. As I was checking the apples I keep for the Blackbirds I noticed a couple going bad. That gave me the idea of cutting a good one one in half and filming it over several days, one shot every 10 minutes.
That is 6 each hour, 144 photos each day. Each day of shooting producing about 5 seconds of video. The camera card should hold 1,150 photos which may well not be enough, about 8 days worth. I may have to reduce the picture quality a little, buy a larger card or lengthen the time lapse.
The first set up:
The 12V battery is on the
left next to the topless grey box containing the Arduino Nano and associated electronics with a 2
digit display to show how many minutes between shots. It is now
programmable from 1 to 60 minutes delay in whole minutes. That switches on three 12V LED lamps for each photo and fires the 350D.
a short test I decided too much daylight was reaching the subject so I
rearranged things with the apple inside an upturned cardboard box
which should help keep the lighting from the three 12V LED lamps more even day and night.
Only time, a long time, will tell how successful it has been. and whether the battery will last long enough. No problem with the camera as that is powered from a mains adaptor. The lamps are the largest drain on the battery but they are only on for 2 seconds for each photo.
This morning I checked the battery and its voltage had dropped a bit below 11V so the light from the LED lamps had lessened. Fortunately I was able to find a 12V 1A power supply to replace the battery.
