Hi Guys !
So I am using a velleman kit in order to transform AC or DC input into 0->12v DC output....!
It's pretty nice, and you can control the output voltage with a screwdriver.
So I put 3.15v, I checked with a multimeter... input is 12vDC from a external harddrive.
It's work pretty nice, battery is at 100%
But the damn camera will turn off during a time lapse.
I tried everything ( turn the camera -> OFF, in CHDK there is also an option, I tried every thing)
By the way, I tried on a 720IS, and a 490... same problems
Also the time is exactly the time you can set in setting -> LCD screen turn off in : 10s; 30s, 1 or 3 min.... there is no 0s !!!
