Minvestigations into modifying the parameters to allow the intervalometer to make an HDR timelapse have so far been fruitless, the only method which seems to work is using the camera's inbuilt bracketing, but for some reason only for very small intervals. Having looked on the chdk forum i tried to use an alternative setup but this just caused the camera to crash. It also required the camera to be in continuous mode which it will not stay in when off. This should not be a problem when it is running properly since i will only set the number of shots to 1 and then have it set to autorun when the power is turned on by the timer. It does mean that i can't test it until i get the circuit back from Neil.
While i was doing what tests i could it became clear that the power consumption of the camera is greater than i thought - two evenings of tinkering have chomped through 8 AA batteries - this makes me nervous about whether the capacity of the battery i have will suffice and if i need to get a larger battery, will it still fit in the container.
