Regular visitors may well remember my home brew motion detector which I sometimes use to photograph birds visiting the pond waterfall. This time I set it up to monitor any visitors to the bird bath:
Essentially the set up consists, in the background, a room type passive IR detector which activates a relay which in turn activates a wireless release for the camera. That is powered by a 12V gel cell. In the foreground the Canon 350D with Sigma zoom lens set for auto focus mounted on a tripod. The camera being fired by a wireless receiver. Camera was fixed at 1/500 shutter speed with auto exposure.
This time there were many false triggers (over 60 birdless shots binned), maybe moving tree shadows and also me or Penny walking within range, but I managed a few captures. It is a question of things being set up at the right time as the birds tend to arrive at fairly set times of day. Unfortunately I had to cut the session short when it started to rain heavily.
Is that a growth or a ring on its leg?
I can see I will be having some automated sessions throughout the Summer. I keep searching for a decent quality, cheapish camera which would allow externally triggered video. I don't think the trail types are as good quality as they make out and anyway I want something with a zoomable lens.
