Dry ice cooled DSLR………………….05. 08. 29
I designed dry ice cooling unit & CMOS airtight chanber front of the lens mount.
At the left pictres square hole is the entrance for the dry ice to go in and get out.
I could buy 80 pieces of 28mm×28mm×28mm dry ice for USD $6.5 at dry ice store.
It can be keeped in styropor box for about 2 days and at open space 1 piece go 1/5 of it’s height after 30minutes. by blocking the air it keeped it up twice as long. By putting on insulating cloth it hoped to keep up even more.
Using 15cm FPC cable and connector to connect CMOS to mainboard it is more neatly connected than before.
Luckily I could get 32 pin, 1.0mm pitch, 15cm FPC cable so I was able to do jobs with preexistence CMOS and FPBC.
The boundary sides that cable passes(CMOS chamber > Dryice chamber > camera body)was sealed with silicon calking.
For cable wiring, I fixed camera bosy’s mirror upward, and removed shutter screen and the cable passed through that opened space.
