Here are some sample images from the video microscope. All of these images are one quarter resolution of the camera for web viewing. The setup I was using:

An Arduino Uno at minimum zoom(18mm):

At maximum zoom (108mm) with the board directly on the work surface(13" working distance):

At maximum zoom (108mm) with the board propped up to 5" away from the camera:

An older 8052 computer board with UV EPROM minimum zoom:

The EPROM at maximum zoom (The distortion in this image is from the window of the EPROM which is not flat)

A line sensor from a scanner:

A board on the work surface with an SO-8(center), a SOT-23(lower right), 0402 passives and smaller parts at maximum zoom:

The system has been very usable this is as a soldering microscope, providing plenty of magnification, and a large work area due to the 13" working distance. While not easy to show here, the update rate of the camera depends on the exposure, but easily supports 30fps with no visible delay.
