Picked up a Logitech C270HD 740p webcam on ebay for about $23. While waiting for hurricane Irene to arrive, I’ve been prodding about the innards, mostly the CCD element, looking for anything interesting…

Do you know is it possible to remove autofocus module from this cam?

To my knowledge, there isn’t an auto-focus feature on this camera. I have completely removed the lens housing via the screws on the back of the PCB to gain access to the CCD element. By short circuiting these and feeding external signals to the pins, it is possible to create a range of effects. Otherwise, this particular camera produces some very nice abstract color fields all on its own in lower light situations.

Do you have any pictures of the lens housing or can you offer any advice as to how you get into the camera. I’m guessing the front facia pops off?
I have recently purchased on of these with a view to use as a weather camera but it does appear to be fixed focus and only quite close to the camera 2-3 meters max. Beyond that the image does start getting quiet blurred. I would like to experiment with different lenses to see if I can improve it.

It has been a while since I opened this one and don’t have it in front of me. There is one maybe two screws on the back, possibly behind a sticker. If not, then to open, simply use a pen knife to pry open from the edges. The lens housing is attached to the PCB and you should be able to adjust focus there. If you wish to remove the housing and try different lenses, you’ll have to loosen two screws that hold the PCB in place in order to access two more screws responsible for holding the lens assembly in place.

The decorative front plate pops off. There’s a thin slot between the front and the rest of the case on one long side and one plastic tab and slot on the each of the other sides. Behind the decorative plate, three very small screws attach the front to the back of the housing. The lens is adjustable but fixed with a small blob of loctite. If you remove that, you can turn the lens to adjust the focus.
