Hi Trev,
I have been experimenting with cooling my camera with a peltier cooler and cpu heatsink for sometime. It`s definitely worth giving it a go I reckon....Either by enclosing and chilling the whole camera (like a cold winters night) or directly to the cmos..
Still contemplating how to modify the camera internally as yet to make it more efficient? but a copper plate on the back of the cmos bridged to the cold finger would be the way to go..
At he moment I just attach via the tripod socket and I get maybe 7-8 degree C drop inside the camera. But do get some condensation on the base and sometimes ice..Cold finger is a 4mm thick piece of Alluminium. Also a lightwieght foam surrounds will be in the making to insulate it more and get the temp down even more.
Attached a pic of what I have been using so far..
I would be interested in info about that kit but Trev! as I am after a way to monitor and control the peltier..
I am aiming at getting the camera a few degrees above 0 on warm nights..
cheers Gary
