I still don't have my RF link modules. I therefore decided to see if I could build a timelapse camera. I have an old Sony DSC S90 which I was happy to play with.
Sadly the Sony doesn't have any interfaces for electronically triggering the shutter. This meant I had to resort to taping a servo to the camera to press the shutter button. This is what the results look like.
I have only tested this with the batteries out of the camera so far so I don't have a results video yet. I will hopefully make one in the next few days.
The code which drives my servo is available here.
