USB microscopes\?

[Allen Rout]

I'm thinking of doing a sharpening demo or class.

It'd be nice to be able to examine things closely and repeatably...
Does anyone know, do we have a computer-attached microscope around
somewhere?

I know this is an area that can get arbitrarily expensive... but I'm
looking for the cheap quick fix first.

I'm full of fantasies: Maybe a beagleboard attach, with a card reader
and a Big Red Button. Swipe the card, and it knows who's looking at
samples. Then hit the button and it mails a frame to you?

I'm getting ahead of myself, got to teach the beagleboards to talk to
the card readers first, but I think that would be a neat application.

We have or used to have one like the following:

Just looked around the space and couldn't locate it, but I bet it's
here somewhere.

Perhaps something like this might work too:

I've been unhappy with the low-end digital microscopes - If you want to get all analog, though, I use this:
 
   http://www.magiscope.com/The-Magiscope.html

as a field microscope - great optics!  Can bring it in...

It's also an indestructable design - originally designed for kids (as they say, of all ages)

Ah, how about a real binocular microscope?  It gives you quite a view.  Both are fun!  What are you sharpening?  If you're talking about knives or woodworking tools I have a LOT of sharpening stuff, in the form of japanese water stones, and accessories.

I am reminded of the Foldscope.
