yet another accurate intervalometer (new version, may need a non-official CHDK build)[]
- Written for/on: Powershot A710
- Also works on: Should work on any VxWorks DIGIC II -cam without modifications, needs to be modified for at least DRYOS-cams. (uses property cases, see the script)
- Required CHDK build: Anything recent with get_exp_count
Script version 20080419
Quite simple bloated & accurate(ish) intervalometer. Sequences (=1 shot and up) are triggered every specified interval (or - if not possible - (almost) as fast as possible) rather than after waiting the specified time. The length of a sequence can be measured by exposures or time. Same goes for the entire intervalometering. Should be quite self-explanatory.
(Naturally this script can be used for bracketing, e.g. HDR stacking. Just set the appropriate bracketing in CHDK menu.)
Hope this is confusing enough...
Feel free to contribute.

yet another accurate intervalometer (old version)[]
- Written for/on: Powershot A710
- Also works on: Should work on A6x0 and S3.
- Required CHDK build: Fingalo's ver 121 and up
Script version 20071231.
(Not extensively) tested OK with (slightly modified) Fingalo's ver 128 (needs get_tick_count and a couple of constructs).
Quite simple & accurate(ish) intervalometer. Shots are triggered every specified interval (or - if not possible - (almost) as fast as possible) rather than after waiting the specified time. Should be quite self-explanatory.
One can either set a number of photos to shoot or a duration (min+sec) which to shoot photos for. Hope this is confusing enough...
