yes I need 1.5 amps, 1.2 at least as that is what my camera is rated, I want to power it off a 12 volt battery, to eliminate the need for AA batteries and constantly removing the tripod shoe from the camera to get to the batteries, the screw socket is plastic and will end up wearing out, I can commonly use 12 for other stuff as well,
I was also wondering if it was possible to make my own PC power supply, I mean most stuff on mother boards now has it's own regulator anyhow and if the software is correct (speed fan) there are continuous fluctuations of 100 mV or more
