I said I'd put up some pics.
Matthew - with the cooler box - once the camera is installed inside, I usually put a couple of ZIP-ties on both tnd to hold the faceplate rigid.
The Digital temp controller has an external temp sensor. I run that inside the box with the other cables and attach the sensor to the back of the camera with a blob of blue-tak.
The TEC draws about 4 amps from memory so it wants a reasonable power supply. I have been in the habit of putting a 5 Amp fuse in the positiv lead to it - just for safety sake.
I think the temp controller is currently set for 6min to 8 max temp. That's a good place to start. There is a fair amount of hysterisis (tendency for the temp to keep getting cooler on the way down and hotter on the way up - by a few degrees but that does settle down somewhat. I was going to add a simple PWM to the power out to the TEC to drop the voltage going to the peltier a bit to see if that had a moderating effect on that hysterisis. Didn't get around to doing that though - that's a project for you if you want one.
