These are photos taken of a shot shell (pierced primer from too long of a firing pin) with an inexpensive USB powered microscope that I found on Amazon (I think). It is called zOrb by Carson optical and was about $40. It is focus adjustable and will capture stills. Lit by 4 LEDs. 640 x480 resolution. It does just as advertised. It is came with a CD that had the driver. easier than using a loop or hand held glass for close up inspection of all kinds if stuff. Just a heads up…I like it when a product works.
