I had a couple of old car-fridge things lying around from a previous "project" and decide to have a look at them as possible DSLR chillers. They're minus the peltier coolers - which were not much chop anyway and were air-to-plate types anyway - not air-to-air. The skeletons weigh in at about 1100 gms and the one shown is 235x175x235 (LWH).
I have taken off the padded top and exposed the hinged plastic top which 2mm thick. Then I cut a centre hole for the T-Rig connection to the DSLR and also drilled a 9mm hole and tapped a thread into it and a bit of aluminum plate that holds the dessicant plug in place.
The hole in the side where the peltier formerly sat seems a good size for an air-to-air replacement. It's got an existing opening about 80x80mm.
Lessons learned so far:
1. Don't cut the hole for the T-Ring connection dead centre. DSLRs tend to be lopsided and by doing it this way, I was forced to align the camera 90 degrees to the way I had imagined it.
2. Curse that bulbous nose the EOS Flash assembly has because it sticks out in front of the camera by about 5mm and made it necessary to cut a shaped hole in the top plate which I will have to cover over later.
Here's some pics. The original chillers boxes came from Dick Smith and cost about $30 bucks each. They are probably sold under a range of names though and I'm sure you'd be able to locate some easily enough.
