You can enlarge your video image with the appropriate software. You
may end up seeing scan lines and have focus problems, but it will be
larger. I have some software that came with a microscope camera that
does this quite well. I don't recall the name right now.
I have fair collection of vision aids. All of them work for specific
functions, but none of them work for every possible situation. Here's
my list:
1. 3.25 diopter reading glasses. I get these at the dollar store for
ummm.... $1/ea. They're junk and are treated accordingly. They're
what I use most when I want to inspect a PCB. I also have some other
power reading glasses for reading.
2. Surgical or dental loupe binoculars:

I have a similar 3.5x-420mm binoculars that fit over my $1 reading
glasses. They're also available in:
2.5x-320mm
3.5x-320mm
2.5x-420mm
3.5x-420mm
and maybe some other sizes. I also have an LED light that clips onto
the glasses (or my hat).
3. USB camera/microscope something like this:
http://www.ebay.com/itm/351620052002
Most of the specs are lies. Mine is 640x480. Here's some sample
pics:
http://802.11junk.com/jeffl/pics/USB%20Camera/640x480/index.html
What's important is the LED ring light, which produces shadow free
illumination. I also have a ring light for my microscope.
4. Trincocular microscope. The 3rd pipe is for the USB camera. Be
sure to get a camera with a 0.5x expander.

Microscope.html
5. Inspection type binocular microscope. This one has about 2"
working distance and should be usable for soldering SMT parts.
However, I'm short on eye pieces, the boom needs work, and the optics
need cleaning. No photos.
6. Assortment of Fresnel and convex magnifier lenses and hand
magnifiers. Also, a few illuminated jewelers loops. I keep these in
the car for service calls, where the larger devices would get in the
way.
7. Various digital cameras with macro lenses or built in macro
features. It's often easier to inspect or enhance a digital photo,
than try to see detail through the lens.
Good luck...
Funny that this subject has come up at the same time that I'm looking for
a
hobbyist-priced stereo microscope for SMD assembly and rework. A good
stereo microscope seems indispensible now that almost everything
electronic is getting so small that only robots are capable of handling
and assembling it.
I've been looking at the AmScope line of stereo microscopes,

I've been looking at the AmScope line of stereo microscopes, which are
available directly form AmScope and Ebay, for similar prices. The ones
I'm interested in are the model SE400X 5X-10X Stereo Boom Arm Microscope
(Ebay item 140927802323) and the 7X-45X Trinocular Articulating Zoom
Microscope +
Ring Light (SKU: SM-6T-FRL on AmScope.com).

I picked up an AM-Scope from Ebay a few years ago and use it all the time.
Works great!! This particular unit has up to 80X with a different insert.
I've only used the higher mag once but it was useful for the task.
These take a little practice, but are best for SMD work.

Check eBay # 400334443106 This is the same size as the crummy fluorescent
ring light we got, it sticks about one whole INCH below the rest of the
microscope, and also is almost 2" wider in diameter than that part of the
scope. Really gets in the way of working on things. So, I do not recommend
this specific light. What you want is one that fits up higher around that
black conical part, just under the white ring with the thumbscrew in the
first picture.
1I have a customer who does SMT repair work and I recently had him help me. I
watched him replace an 8 pin SOT for me. He had a dual lens machine like
something you might see on CSI.

This still fits below the black cone of the microscope objectives,
and is larger in diameter. What I made fit around the upper part of
the black cone, just under the ring that holds the microscope. So,
it is much less in the way of your hands, tools, etc.

I need to purchase a magnifier so that I'll be able to do things like replace eproms and other small SMT's. I'm not looking to do LSI's with 150 pins Etc. Just mostly smaller stuff. For instance I currently have a board that needs an 8 pin Eprom replaced. I thought that I could do it with the magnifiers I have but the stuff is Just too small. I tried using a high res TV camera with a varifocal 3.5 to 8 mm lens but it doesn't make the image large enough. I was wondering what people are using to do this. Thanks, Lenny
