I have decided to look inside my Cowon AW1 ( AW2 must be the same )
Also, just in case tried as an assurance I wanted to "re-focus" lens and see how well they are focused. After my "re-fucusing" test I must say that the lens on my AW1 were well focused from factory, but those who might want to perform Cowon AW1 lens focusing, you might find some useful tips ( photos ).


The built and assembly quality is truly at high-end level, no complaints at all. They have used 3-layer PCB structure and fitted all needed hardware into one "capsule"-look body, hence the name of this range: "Auto Capsule"

Cowon AW1 uses Processor (CPU)TMS320DM368 ” from TI ( Texas Instruments )
CMOS Sensor is OV2710 from Omnivision
Battery: 3.7V 0.4W 95mAh

Lens are glued to the lens housing / holder with thick layer of special glue.
Usually ( with other dashcameras, which have only few drops of glue ) I scrape off it with some sharp tools like flat-head mini-screwdriver or needle, but it was very hard to use same technique on AW1, so I had to use hot-air soldering station.

I am using AOYUE 968A.

Attached smallest available nozzle to hot-air gun and tried to melt lens housing glue, but process was inefficient and took a lot of time, so I changed to soldering iron, melted glue and scrape off excess.
After that I have marked focusing "points" on lens and housing and started "re-focusing" test, but as mentioned at the beginning, focus on AW1 was perfectly good from factory. So it was just an assurance test to make sure everything is OK.
