Cooled (fan) modified QCAM

Cooling fan for PC(DSF-600); 60mm fan, 3100rpm, 12V, 0.13A, was
attached to back of the camera case. Electricity, both of cooling fan
and QCAM itself designed to be from ADB(Apple Desktop Bus) port.
Noise reduction was terrific as bellow.


A frame of dark movie at the room temperature(+20C)
Christmas lights like noise disappeared, and this condition lasted
during the hole experiment time(20 minutes). Sorry for no astro-image,
it's cloudy tonight.
