I am fed up with getting Amp Glow in the corner of my pics when doing Long Exposures, but I know that cooling decreases it.
So I have made a very basic cooling device for my Toucam.
It is a small fan from an old computer attached (temporarily) to the back of the Toucam. I know I can fit Peltier Cooling inside the Camera, but this is a test of a very simple method anyone can do if it works. Plus it's cheap
The 1st Test:
I tested its performance today for creating cold air. The Air temp outside was 8 degrees during testing. I switched on the fan and held it close to my hand. Within 1 minute my hand was starting to sting badly from cold!!!
The 2nd Test:
I strapped the fan to the Toucam and ran it for 3 minutes. Then I removed the fan and felt the Toucam body. It was extremely cold to touch!!!
So far so good.
Now all I need is a clear sky and I can test it on Long Exposures. The temps at night are dropping to around 1 degree here at the moment, soon to be in the minus region, so I am hoping the fan will make the camera go down to somewhere around -5 degrees or lower.
If it all works, I will mount it properly to the camera body instead of by the Rubber Bands I am using now.
I will do a report on its performance when I get some sky.
