Quote from: Mlapse on 17 / January / 2019, 02:44:14maybe I'm mistaken and it is normal for an aps-c sensor, but the log i posted a while back had tsens of over 50C, the log from a few days back still had 45C. although iso was only 200.The interval was 30 sec, so i can't imagine that is quick enough to heat it up that much.FWIW, I wouldn't be surprised to see >50c in warm ambient conditions with a script like rawopint. (lack of surprise should not be taken as any judgement on whether it's healthy or not )A user reported problems around 80c https://chdk.setepontos.com/index.php?topic=13501.0 with cameras in an enclosure.

How to do shutdown / awake cam with lens kept extended?
Nice, in tourist´s handheld scripts it might be some microtuning to loop something likeCode: [Select]set_iso(temp)todo()shoot()set_iso(1)sleep(...
set_iso(temp)todo()shoot()set_iso(1)sleep(...
--[[--@title dimmer.lua@chdk_version 1.4--]]--function dimmer(tim,dim)dim=dim or 1tim=tim or 0local iso=get_iso_mode() set_iso_mode(dim) press("shoot_half") wait_click(tim) -- or md_detect... release("shoot_half") set_iso_mode(iso)enddimmer()
I don't understand what the iso_mode manipulation is intended to accomplish.

In order to reduce the temperature increase, the reading of the sensor had to be prevented during the breaks.
I agree. I found "amplifier glow" & thought, that iso heats that amplifier, cooking sensor...
I'd expect half press to run hotter than idling in live view, because it draws more power...
the camera normally uses a higher frame rate and likely clocks some things faster.
