Thought I'd better do my own thread on this rather than hijack other peoples.

Been working on a build for the KM 7D, my expendable camera with the IR Mod done. My original plan was to mount a copper slab in behind the sensor with more copper down to a TEC beneath. Fail, not enough room between the steel frame and the rear control\LCD panel.

So decided to come in from the side and under the steel frame instead. Also decided as I wasn't going to attempt sub zero results I'd use aluminium as the finger instead. After copper it is the most conductive element around apparently.

So hacked a huge hole in the steel frame and case and patterned a finger to slide in through that. Good old Duct tape gives some isolation of the components and even secures it within the frame.. Then created a sandwich of the heat sink, TEC, finger and clamp and some Styrofoam insulation. Added a small fan to assist air flow.

I trimmed the rear protruding pins of the sensor from the back of the board to give a bit more space and I'll add the silicon slab as a heat transfer medium, electrical isolation and moisture excluder. It will be ready tomorrow.

Unfortunately this camera does not communicate and I don't know if temp is shown on the EXIF data even but at 5 volts I should be able to knock 10* or better off the internal temp and kill the amp glow in one corner and prove operation.

Pics should give you an idea of the build. The securing bolt goes through an oversized hole in the finger and is shielded inside a plastic tube.

Apologies for the quality of some of the pix
