Thumbs up Finally bit the bullet-Cooled modded 40D v1

Hi folks,
Finally, well almost have my newly modded and cooled DSLR up and running!
Tell you what, that was real fiddley stuff! Looking at the tutorials etc on doing these mods you don`t realize how small alot of these connectors are!

One thing I have learned also was DON`T USE SUPERGLUE! Some people mention to use super glue but on drying I found the superglue left hazy rings in the corners of the Baader filter. Had to rush into town and get some Acetone to clean off the superglue, and what a hastle to remove the filter again from the frame. Instead used some black silicone which worked ok but took forever to cure. Next time I will use some 5min epoxy. Getting the filters spotless was also a challange as everytime you got one clean and put it aside to do the other, those dust spots would appear again. Got it almost dust bunny free except a few in the bottom corner which only show up a high F/ numbers.
Next I fixed a copper cold finger to the back of the Cmos and cut a slot in the plastic side cover under the usb connector. Not much room but managed to squeeze it in with a few layers of electrical tape for insulation.
The cooler is a old AMD cooler with a 4amp TEC running of a 12v supply. Still havn`t made the control box to regulate the TEC but have all the components ready to assemble. Not sure how accurate the controller is but was told it was accurate to 1C.
Gave it a quick bench test to see how it all runs at 22-c and after the cooler was running for 15min....See attached pics.
Shall get it finished in the next few weeks hopefully.
Have to work on any dew problems as yet..any thoughts appreciated!
Thanks for the inspiration and help Martin!
Always wanted to try this !`m glad I didn`t kill the sucker!
Shall update when the control box is up and running. Hopefully I can keep the Cmos down to 0c
cheers Gary
