My Pencil as Seen by a Germ

Disclaimer - No hamsters were harmed in the taking of this photograph.  No duct tape was used (although it came close) and most of all no money was spent.

I threatened to do this a while back.  I was given a webcam a few years back as part of a package to get us experimenting with how to use technology in the classroom.  It was not an expensive webcam.  It was  not a great webcam but I did use it.  Then I got bored of it.  Close to a year ago I threatened to find a way to hook it up to a microscope to take close up macro pictures.  Well I finally did it.  It was really easy.  It was Friday and I had a prep last class.  Could you blame me?

On the Instructables site I found this how-to.  It was as simple as taking out the lens and reversing it.  A microscope was not necessary.  All you need is an external webcam.  While I had to do a little bit of work to get it to work it is completely reversible.  Focus is really touchy and you need a lot of light but I would love to see what could be done with a webcam that has better than 640x480 resolution.  Read the how-to and do it yourself.  Voiding warranties is a huge amount of fun.  Trust me.

Oh yeah - show a science teacher near you.  Mine was as excited as a kid at Christmas.
