I came across this link awhile ago, and now I have the components to
start building it. My idea for the project is to use it in macro
mode for viewing SMD mounting work on a monitor.

The inventor used a regular telephoto lens, but I have a macro
telephoto lens now of the correct lensmount that focuses quote
closely, yet should allow a decent working distance of the front of
the lens and the PC board. I'm using some 1/4" x 3" birch from Home
Depot for the box.
The main issue is the webcam itself. For the prototype, I didn't want
to sink a lot of money into one, so I bought a very basic one. With
the software, it only does 640x480, which is a pretty small window on
my monitor. The unmodified webcam can focus down on an SMD enough to
read the labeling, but only at a very close proximity.
I also bought a lot of high intensity white LEDs and dropping
resistors to make a ring light to use with all my SLR cameras.
Anyone else built anything like this?
Cheers,
Ted
