  1. Hi All, I finally had a chance to start my active cooling mod of my astro modded Canon 40D. Initially I started with designing the shape of the cold finger and creating a to scale template on paper... I made two designs, one with bends around the sensor, and one which is mostly flat with minimal bends. I went with the latter since I figured that I will not be able to bend the copper plate with such precision using my available tools... ie two pieces of wood. I cut out the cold finger on the copper plate and after bending the cold finger into shape, I realized that there was a bit of a gap between the copper and the sensor... ...so I cut out a piece of copper 1mm smaller than the sensor on each side and inserted this in between the cold finger and the sensor. Hopefully (with the use of heat transfer paste) creating contact and being more efficient in extracting the sensor generated heat. I used the existing screws to hold the cold finger in place, three screws should be secure enough to hold it in place. Now that the cold finger is in place, it is time to put the camera together. There is not much room inside the camera and so the mod is very tight. The main PCB is a tiny bit offset and inserting the compact flash card is tighter than normal, as is inserting the mini-USB cable. At this time I was expecting the camera not to power on but... ... it's alive... ALIVE!!! I've taken a shot of the light without a lens and the white frame tells me that the sensor still works. There is enough room to use the side connectors as needed. The most important connectors are the USB connector which will be used almost exclusively and the remote trigger connector which I'll use when I'm not using the laptop. Part 2 of the cooled DSLR mod is a success, all that's left now is to bend the outside plate 90 degrees to the front, install the peltier cooler, heat sync and the temperature controller.... Clear skies, Mariusz
