Dave, you have some impressive equipment in your lab/workshop, especially your overhead video
camera/macro/microscope gear we see lately on Youtube, mainly with your
SMD placement/soldering! 
Of course we can't all afford that gear, but with the proliferation of SMD stuff now, we have visual probs!
As a
stop-gap at least, for the 'masses', I'm playing with a set-up using my Android
SmartPhone as a camera,
to show real-time video full screen & magnified, on my
Laptop screen!! for delicate soldering work etc. I'm using
a phone App called '
DroidCam', and it's corresponding Client software on Windows. It works via local
WIFI, or
USB. The basic App works, but is limited. The 'paid' App is called '
DroidCamX' and is only about
$4.50!!, with many
more features including PC control of Zoom, Brightness, Orientation & photographs. It works great! and includes
working in HD 720p 16:9. I just have to make a frame/holder to position it above my work.

Maybe worth a look at by others...
