Ricoh GRD AC to DC power supply

Ricoh GRD AC to DC power supply
On my first instructable - http://www.instructables.com/id/Galvanized-Plumming-Parts-Lamp/ i had a link to a youtube video that was a time lapse that formed part of the build guide for the lamps. 

I'd completely forgotten about the funny little attachment I'd built for doing the actual time lapse. I'd been planning a 4x4 trip into central australia and left my run a bit late to buy an AC to DC power supply for my camera. I rang every store in Melbourne but any that could get one would be up to 14 days. So stressing my head off I went and bought waaaay too many AAA rechargeable batteries with the plan of using them in my Ricoh GRD camera, and charging them off an inverter so I could do a time lapse of my entire driving trip through the desert. But in testing I could only get about 1.5hrs per set of batteries. Which meant pulling the camera off the mount in the car and changing the frame too many times for a smooth video.

What to do?????

I know! I'll build one!!!

Step 1AC to DC converter

AC to DC converter
Looking at the bottom of the camera I saw that it needed 3.8V DC. So I went down to the local electronics store and bought myself an adjustable AC to DC converter. I picked a 1500mA one as rechargable batteries have about 900-1300mA and a mate told me it wouldn't be an issue. (I'm not an electrician so don't quote me on the numbers! I asked people who would know and went with what they said).
