This is a modification of the c270 webcam. Unscrew the lens, turn it by 180 degree and use the cam to magnify objects. I also replaced the green LED with a 0805 warm white one. The screws used in the housing are 1.4mmx10mm Phillips head. The case offers also the possibility to install it on a M4 thread. Illumination can improved with a bit of tin foil which is glued in the top of the lid.
