Default USB camera for powder check

The thing that scares me the most in my reloading endeavors is a squib.
To
visually check every case for the proper amount of powder is inconvenient
and slow. (but better than two in the tube or a hand grenade) I load
/shoot about 1k/month. So, I'm going to mount a small camera that will
display a real-time video that is easy to see from my position operating
the
press. I have a five station progressive press and there are a few
powder-check dies available that work very well, but I don't have a
station
to spare between the powder dump and the bullet seating. I use a
separate
crimp die after the bullet seating. (I did start to design an eight
station
press but how obsessive CAN I get?) Get just ONE squib and you'll never
shoot the same, it'll always be in the back of your mind. Thankfully,
I've
never had a double-charge!

I can mount the camera on the ram so it's focus it constant or I can
mount
it to the press if the camera will auto focus fast enough to be useful.
Ideally, the camera would have it's own LED lighting source.

Any recommendations on a camera or refinement of my idea?

Imagine if the camera took a still at the bottom of the stroke and
instantly
compared the image to a "standard" then sounded an alarm if the image was
too far from the standard and locked the press? Again, a powder-check
die
would do just that but I would not be able to use my bullet feeder or my
separate crimp die.



Have you looked at a USB Microscope?

http://www.google.com/search?q=usb+microscope&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-USfficial&client=firefox-a


I got one, it won't focus any farther than about 2". I need at least 4"-6".
I DO like the scope but It won't do it. Too bad, it has two levels of LED
lighting in a ring config.



Different models have different focal length, but the sellers rarely
post the full specs.

http://www.toysrus.com/product/index.jsp?productId=3565514 has NTSC
output for $19.98. It is a spherical design, and runs on AA batteries
in a separate box. It's a toy, but could have some use around a shop or
production floor.

The only problem I can see is that they recommend that the user be
eight, or older. I suppose you could lie... ;-)
