A break in the dismal spring weather yesterday allowed the Reg's Paper Aircraft Released into Space (PARIS) team to run an outdoor test on the main payload Canon PowerShot A560. PARIS: Sponsored by Peer 1 The camera has been given the Canon Hack Development Kit treatment which allows us to run a BASIC script intervalometer, …
The Canon Powershots are notorious for caning the battery and switching off when they've still (theoretically) got a load of charge. I am *amazed* you got 45 minutes out of it.
I did a seven day timelapse with an A560 a while ago, and ended up hooking the thing to a car battery via a cigarette voltage convertor. It worked a treat!
Most likely reason for camera powering off is some memory leak.
Some Canon camera models have very little ram memory and each time scripts run and do memory allocations and de-allocations the memory gets a little bit more fragmented so in the end there's just not enough continuous memory space to allocate for snapping a picture and in the end the firmware just calls it quits.
Just a field report of my own: The modded Canon firmware, while very nice, really chews up your battery. Furthermore, unless you took the time to properly calibrate the modded firmware's battery stats measurements, it might not be reporting the battery correctly anyway.
My testbed is an Ixus 850 - it lasts for about 48 hours for about 1,000 shots on standard firmware, about 3 hours for maybe 100 shots on the modded firmware.
