These instructions are for a very simple, webcam microscope for scientific and instructional fun and knowledge. This particular set up will not render super high def images or provide electronmicroscopy. This is a proof of concept DIY display we use at maker and science festivals to give youth and adults an idea of how they can make their own webcam microscope at home. Little kids love it, because it's easy to use and see and on a computer monitor; adults like it because it's not intimidating to do. It's also a fun way to repurpose an old microscope and mash it up with some modern tech. And it uses duct tape. What's not to love?
On the old '70s era microscope we have (I had said "50s" before, but stand corrected on the microscope vintage! - it's old!), that's a simple matter of loosening the tiny screw and removing the eyepiece. Put the screw(s) in a ziplock so you don't lose it!
