I will be posting some projects in the coming months that will be better understood and replicated with a microscope. But, I realized that many people do not have a microscope, or even have access to one. I know, because I have had mine for only two years and have had to improvise in the past. This conversion is the result of that improvisation. The older webcams failed to have a manual focus and literally had to be torn apart to be used as a microscope. But the current webcams, particularly the cheaper ones, are manually focused and work just fine. Please watch the video and I will follow the video with some links, webcam information, and one more image from a screen shot. Enjoy!
The webcam that I used is a Gigaware 2500465, and it is available at Radio Shack and online. But any inexpensive webcam will work if it has a manual focus. One thing to consider is that the lenses on most webcams are plastic, not glass, so there may be some unwanted distortion. But, for the price, it is an acceptable trade-off.
The full conversion is available as an instructable by Zephyris, (Richard Wheeler.net) here. I appreciate his effort to provide good information for us all. It really is fun to look at the smaller side of life and to be surprised by the miniature world around us. Please comment or ask any questions and I will try to answer them for you... Ken.
