Auto pictures from camera

The Canon powershot A490 turned up & I managed to get the hack kit onto the SD card.

There is a standard script for automatically taking photos after a set time period, so I tried it looking out of the back window:

(must be pretty near the top of the 'most boring video' stakes!)
There were just under 500 pictures taken over 4 hours, at 1 shot / 30 sec, before the batteries ran out.  This was all with the screen on (I've not managed to get the script to turn it off yet) so should last for a 5 hour balloon flight.
