\oh, right... :P I draw in the air with flashlights or throw burning steel wool everywhere. The end of exposure signal is to tell me to stop working.
So all you need is a script to "press the shutter button" (assumes camera setting are preset by you) and then blink the "auto focus" lamp when the shot completes ?   That's about three lines of code -  I can do that tonight and test on my camera first if that's all you need.

That's it! Only I'de like to press the button (or hitting the remote) to start the exposure, instead of having the script do it.

When you put the camera into <ALT> mode, you press the shutter button to start a script.  Which is pretty much what I think you want to do. 

For no extra charge,  I'll post a version that waits for a USB remote as well.

Update :  the reponses to this post were lost when the forum migrated to a different server.  Here's the script we can up with.  Remember to turn off dark frame subtraction to get the LED to light when the actual exposure has ended.  Dark frame info can be edited with PC software after the fact. http://www.mediachance.com/digicam/blackframe.htm

Code: [Select]
--[[
@title Light Painting
@param a LED number
@default a 2
--]]
sleep(1000)
shoot()
repeat sleep(100) until get_shooting() == false
set_led( a, 1, 0)
sleep(5000)

Hi Guys,

First off I want to say Many Thanks to all the workers on this project for all their hard work and dedication. I'm sure it's not at all easy to keep up with all the new models and firmware changes, but please know that your work is much appreciated.

I'm running CHDK 0.9.9-1364 and SX130is Firmware 101C and have just joined the forum. I've read all the SX130 pages (whew!) to catch up with the latest and hopefully not to repeat problem reports.

I want to bring up the fact that Disabling Overrides does not seem to turn off the Quality Override setting, even when the OSD screen item says NO OVERRIDES.

I'd like to be able to quickly turn off Superfine when doing multiple exposure bracketing, because as others have reported Superfine will crash the system with too much data when shooting 3 bracketed shots of a highly detailed scene.

Also, the Battery Temperature is reported incorrectly as a high negative number even at startup (now showing -146 deg F). Same problem if using not Fahrenheit. The other temperatures seem OK.


Any word on these?

Thanks!

@w2ki

As far as I know SX130IS has no battery temperature sensor, so CHDK temperature value for batteries has no sense. It's just a number without any meaning. You can only measure CCD temperature and Optical as well.

I don't know about quality override, wait for somebody could answer this question.

Thanks, Outslider, that certainly explains the crazy reading. I'll stay tuned for an expert opinion about the Quality override issue.

For what it's worth, I just installed build 1352, and what I call the "failure to disable Quality override" problem is still there.

Is this a known problem, and if not, am I correct in reporting it here or should I do something else?

Thanks again.

Sorry, that should read "just installed 1372", not 1352.

Correct - the 'Disable Overrides' option does not affect the 'Quality Override'. Can't tell you why, that's just how the code is written. You can log a 'feature request' for it to be changed and see what the general consensus is (http://chdk.setepontos.com/index.php?board=9.0).

The SX130 code comments indicate that the battery temperature function does not work and crashes the camera. However the comments look to have been copied from another camera so it may just never have been implemented and the code to return -99 used instead.

Attached is a version with that calls the firmware battery temperature function (as found by the new signature finder). Please test this and post back if it displays a reasonable temp value or crashes.

Phil.

Edit: Attachment removed since it crashes the camera.

Thanks for trying, Phil, but it doesn't look good.

The pgm crashes each time right after going into Record mode after loading CHDK in Playback mode and then selecting Battery (or All) in OSD>Show Temperature.

It was worth a try.
